Note that giving two different forms of the same flag in the same command invocation is an error. - -#### Values from the Environment - -You can also have the default value set from the environment via `EnvVar`. e.g. - -``` go -app.Flags = []cli.Flag { - cli.StringFlag{ - Name: "lang, l", - Value: "english", - Usage: "language for the greeting", - EnvVar: "APP_LANG", - }, -} -``` - -The `EnvVar` may also be given as a comma-delimited "cascade", where the first environment variable that resolves is used as the default. - -``` go -app.Flags = []cli.Flag { - cli.StringFlag{ - Name: "lang, l", - Value: "english", - Usage: "language for the greeting", - EnvVar: "LEGACY_COMPAT_LANG,APP_LANG,LANG", - }, -} -``` - -### Subcommands - -Subcommands can be defined for a more git-like command line app. -```go -... -app.Commands = []cli.Command{ - { - Name: "add", - ShortName: "a", - Usage: "add a task to the list", - Action: func(c *cli.Context) { - println("added task: ", c.Args().First()) - }, - }, - { - Name: "complete", - ShortName: "c", - Usage: "complete a task on the list", - Action: func(c *cli.Context) { - println("completed task: ", c.Args().First()) - }, - }, - { - Name: "template", - ShortName: "r", - Usage: "options for task templates", - Subcommands: []cli.Command{ - { - Name: "add", - Usage: "add a new template", - Action: func(c *cli.Context) { - println("new task template: ", c.Args().First()) - }, - }, - { - Name: "remove", - Usage: "remove an existing template", - Action: func(c *cli.Context) { - println("removed task template: ", c.Args().First()) - }, - }, - }, - }, -} -... -``` - -### Bash Completion - -You can enable completion commands by setting the `EnableBashCompletion` -flag on the `App` object. By default, this setting will only auto-complete to -show an app's subcommands, but you can write your own completion methods for -the App or its subcommands. -```go -... -var tasks = []string{"cook", "clean", "laundry", "eat", "sleep", "code"} -app := cli.NewApp() -app.EnableBashCompletion = true -app.Commands = []cli.Command{ - { - Name: "complete", - ShortName: "c", - Usage: "complete a task on the list", - Action: func(c *cli.Context) { - println("completed task: ", c.Args().First()) - }, - BashComplete: func(c *cli.Context) { - // This will complete if no args are passed - if len(c.Args()) > 0 { - return - } - for _, t := range tasks { - fmt.Println(t) - } - }, - } -} -... -``` - -#### To Enable - -Source the `autocomplete/bash_autocomplete` file in your `.bashrc` file while -setting the `PROG` variable to the name of your program: - -`PROG=myprogram source /.../cli/autocomplete/bash_autocomplete` - - -## Contribution Guidelines -Feel free to put up a pull request to fix a bug or maybe add a feature. I will give it a code review and make sure that it does not break backwards compatibility. If I or any other collaborators agree that it is in line with the vision of the project, we will work with you to get the code into a mergeable state and merge it into the master branch. - -If you are have contributed something significant to the project, I will most likely add you as a collaborator. As a collaborator you are given the ability to merge others pull requests. It is very important that new code does not break existing code, so be careful about what code you do choose to merge. If you have any questions feel free to link @codegangsta to the issue in question and we can review it together. - -If you feel like you have contributed to the project but have not yet been added as a collaborator, I probably forgot to add you. Hit @codegangsta up over email and we will get it figured out. diff --git a/vendor/github.com/codegangsta/cli/app.go b/vendor/github.com/codegangsta/cli/app.go deleted file mode 100644 index edf02fbc0..000000000 --- a/vendor/github.com/codegangsta/cli/app.go +++ /dev/null @@ -1,275 +0,0 @@ -package cli - -import ( - "fmt" - "io" - "io/ioutil" - "os" - "text/tabwriter" - "text/template" - "time" -) - -// App is the main structure of a cli application.

See the +sections below for further details on formatting and configuration options. + +To dump a variable with full newlines, indentation, type, and pointer +information use Dump, Fdump, or Sdump: + spew.Dump(myVar1, myVar2, ...) + spew.Fdump(someWriter, myVar1, myVar2, ...) + str := spew.Sdump(myVar1, myVar2, ...) + +Alternatively, if you would prefer to use format strings with a compacted inline +printing style, use the convenience wrappers Printf, Fprintf, etc with +%v (most compact), %+v (adds pointer addresses), %#v (adds types), or +%#+v (adds types and pointer addresses): + spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2) + spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) + spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2) + spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) + +Configuration Options + +Configuration of spew is handled by fields in the ConfigState type. For +convenience, all of the top-level functions use a global state available +via the spew.Config global. + +It is also possible to create a ConfigState instance that provides methods +equivalent to the top-level functions. This allows concurrent configuration +options. See the ConfigState documentation for more details. + +The following configuration options are available: + * Indent + String to use for each indentation level for Dump functions. + It is a single space by default. A popular alternative is "\t". + + * MaxDepth + Maximum number of levels to descend into nested data structures. + There is no limit by default. + + * DisableMethods + Disables invocation of error and Stringer interface methods. + Method invocation is enabled by default. + + * DisablePointerMethods + Disables invocation of error and Stringer interface methods on types + which only accept pointer receivers from non-pointer variables. + Pointer method invocation is enabled by default. + + * ContinueOnMethod + Enables recursion into types after invoking error and Stringer interface + methods. Recursion after method invocation is disabled by default. + + * SortKeys + Specifies map keys should be sorted before being printed. Use + this to have a more deterministic, diffable output. Note that + only native types (bool, int, uint, floats, uintptr and string) + and types which implement error or Stringer interfaces are + supported with other types sorted according to the + reflect.Value.String() output which guarantees display + stability. Natural map order is used by default. + + * SpewKeys + Specifies that, as a last resort attempt, map keys should be + spewed to strings and sorted by those strings. This is only + considered if SortKeys is true. + +Dump Usage + +Simply call spew.Dump with a list of variables you want to dump: + + spew.Dump(myVar1, myVar2, ...) + +You may also call spew.Fdump if you would prefer to output to an arbitrary +io.Writer.

BY-SA Compatible License means a license listed at + creativecommons.org/compatiblelicenses, approved by Creative + Commons as essentially the equivalent of this Public License. + + d. Copyright and Similar Rights means copyright and/or similar rights + closely related to copyright including, without limitation, + performance, broadcast, sound recording, and Sui Generis Database + Rights, without regard to how the rights are labeled or + categorized.

Exceptions and Limitations. For the avoidance of doubt, where + Exceptions and Limitations apply to Your use, this Public + License does not apply, and You do not need to comply with + its terms and conditions. + + 3. Term. The term of this Public License is specified in Section + 6(a). + + 4. Media and formats; technical modifications allowed. The + Licensor authorizes You to exercise the Licensed Rights in + all media and formats whether now known or hereafter created, + and to make technical modifications necessary to do so. The + Licensor waives and/or agrees not to assert any right or + authority to forbid You from making technical modifications + necessary to exercise the Licensed Rights, including + technical modifications necessary to circumvent Effective + Technological Measures.

Every + recipient of the Licensed Material automatically + receives an offer from the Licensor to exercise the + Licensed Rights under the terms and conditions of this + Public License. + + b.

No downstream restrictions. You may not offer or impose + any additional or different terms or conditions on, or + apply any Effective Technological Measures to, the + Licensed Material if doing so restricts exercise of the + Licensed Rights by any recipient of the Licensed + Material. + + 6. No endorsement. Nothing in this Public License constitutes or + may be construed as permission to assert or imply that You + are, or that Your use of the Licensed Material is, connected + with, or sponsored, endorsed, or granted official status by, + the Licensor or others designated to receive attribution as + provided in Section 3(a)(1)(A)(i). + + b. Other rights. + + 1. Moral rights, such as the right of integrity, are not + licensed under this Public License, nor are publicity, + privacy, and/or other similar personality rights; however, to + the extent possible, the Licensor waives and/or agrees not to + assert any such rights held by the Licensor to the limited + extent necessary to allow You to exercise the Licensed + Rights, but not otherwise. + + 2. Patent and trademark rights are not licensed under this + Public License. + + 3. To the extent possible, the Licensor waives any right to + collect royalties from You for the exercise of the Licensed + Rights, whether directly or through a collecting society + under any voluntary or waivable statutory or compulsory + licensing scheme.

You may satisfy the conditions in Section 3(a)(1) in any + reasonable manner based on the medium, means, and context in + which You Share the Licensed Material. For example, it may be + reasonable to satisfy the conditions by providing a URI or + hyperlink to a resource that includes the required + information. + + 3. If requested by the Licensor, You must remove any of the + information required by Section 3(a)(1)(A) to the extent + reasonably practicable. + + b. ShareAlike. + + In addition to the conditions in Section 3(a), if You Share + Adapted Material You produce, the following conditions also apply. + + 1. The Adapter's License You apply must be a Creative Commons + license with the same License Elements, this version or + later, or a BY-SA Compatible License. + + 2. You must include the text of, or the URI or hyperlink to, the + Adapter's License You apply. You may satisfy this condition + in any reasonable manner based on the medium, means, and + context in which You Share Adapted Material. + + 3. You may not offer or impose any additional or different terms + or conditions on, or apply any Effective Technological + Measures to, Adapted Material that restrict exercise of the + rights granted under the Adapter's License You apply. + + +Section 4 -- Sui Generis Database Rights. + +Where the Licensed Rights include Sui Generis Database Rights that +apply to Your use of the Licensed Material: + + a. for the avoidance of doubt, Section 2(a)(1) grants You the right + to extract, reuse, reproduce, and Share all or a substantial + portion of the contents of the database; + + b. if You include all or a substantial portion of the database + contents in a database in which You have Sui Generis Database + Rights, then the database in which You have Sui Generis Database + Rights (but not its individual contents) is Adapted Material, + + including for purposes of Section 3(b); and + c. You must comply with the conditions in Section 3(a) if You Share + all or a substantial portion of the contents of the database. + +For the avoidance of doubt, this Section 4 supplements and does not +replace Your obligations under this Public License where the Licensed +Rights include other Copyright and Similar Rights. + + +Section 5 -- Disclaimer of Warranties and Limitation of Liability. + + a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE + EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS + AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF + ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, + IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, + WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR + PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, + ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT + KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT + ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU. + + b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE + TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, + NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, + INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, + COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR + USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN + ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR + DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR + IN PART, THIS LIMITATION MAY NOT APPLY TO YOU. + + c. The disclaimer of warranties and limitation of liability provided + above shall be interpreted in a manner that, to the extent + possible, most closely approximates an absolute disclaimer and + waiver of all liability. + + +Section 6 -- Term and Termination. + + a. This Public License applies for the term of the Copyright and + Similar Rights licensed here. However, if You fail to comply with + this Public License, then Your rights under this Public License + terminate automatically. + + b. Where Your right to use the Licensed Material has terminated under + Section 6(a), it reinstates: + + 1. automatically as of the date the violation is cured, provided + it is cured within 30 days of Your discovery of the + violation; or + + 2. upon express reinstatement by the Licensor. + + For the avoidance of doubt, this Section 6(b) does not affect any + right the Licensor may have to seek remedies for Your violations + of this Public License. + + c. For the avoidance of doubt, the Licensor may also offer the + Licensed Material under separate terms or conditions or stop + distributing the Licensed Material at any time; however, doing so + will not terminate this Public License. + + d. Sections 1, 5, 6, 7, and 8 survive termination of this Public + License. + + +Section 7 -- Other Terms and Conditions. + + a. The Licensor shall not be bound by any additional or different + terms or conditions communicated by You unless expressly agreed. + + b. Any arrangements, understandings, or agreements regarding the + Licensed Material not stated herein are separate from and + independent of the terms and conditions of this Public License. + + +Section 8 -- Interpretation. + + a. For the avoidance of doubt, this Public License does not, and + shall not be interpreted to, reduce, limit, restrict, or impose + conditions on any use of the Licensed Material that could lawfully + be made without permission under this Public License. + + b. To the extent possible, if any provision of this Public License is + deemed unenforceable, it shall be automatically reformed to the + minimum extent necessary to make it enforceable. If the provision + cannot be reformed, it shall be severed from this Public License + without affecting the enforceability of the remaining terms and + conditions. + + c. No term or condition of this Public License will be waived and no + failure to comply consented to unless expressly agreed to by the + Licensor. + + d. Nothing in this Public License constitutes or may be interpreted + as a limitation upon, or waiver of, any privileges and immunities + that apply to the Licensor or You, including from the legal + processes of any jurisdiction or authority. + + +======================================================================= + +Creative Commons is not a party to its public licenses. +Notwithstanding, Creative Commons may elect to apply one of its public +licenses to material it publishes and in those instances will be +considered the "Licensor."

You do that by +adding a single test method in your test file. All your goblin tests will be implemented inside this function. + +```go +package foobar + +import ( + "testing" + .

Goblin will help you to test asynchronous things, like goroutines, etc. You just need to add a ```done``` parameter to the handler function of your ```It```. This handler function should be called when your test passes. + +```go + ... + g.Describe("Numbers", func() { + g.It("Should add two numbers asynchronously", func(done Done) { + go func() { + g.Assert(1+1).Equal(2) + done() + }() + }) + }) + ... +``` + +Goblin will wait for the ```done``` call, a ```Fail``` call or any false assertion. + +How do I use it with Gomega? +---------------------------- + +Gomega is a nice assertion framework. But it doesn't provide a nice way to hook it to testing frameworks. It should just panic instead of requiring a fail function. There is an issue about that [here](https://github.com/onsi/gomega/issues/5). +While this is being discussed and hopefully fixed, the way to use Gomega with Goblin is: + +```go +package foobar + +import ( + "testing" + .

It works in concert with the Go source code generated +for .proto files by the protocol compiler. + +A summary of the properties of the protocol buffer interface +for a protocol buffer variable v: + + - Names are turned from camel_case to CamelCase for export. + - There are no methods on v to set fields; just treat + them as structure fields. + - There are getters that return a field's value if set, + and return the field's default value if unset. + The getters work even if the receiver is a nil message. + - The zero value for a struct is its correct initialization state. + All desired fields must be set before marshaling. + - A Reset() method will restore a protobuf struct to its zero state. + - Non-repeated fields are pointers to the values; nil means unset. + That is, optional or required field int32 f becomes F *int32. + - Repeated fields are slices. + - Helper functions are available to aid the setting of fields. + msg.Foo = proto.String("hello") // set field + - Constants are defined to hold the default values of all fields that + have them. They have the form Default_StructName_FieldName. + Because the getter methods handle defaulted values, + direct use of these constants should be rare. + - Enums are given type names and maps from names to values. + Enum values are prefixed by the enclosing message's name, or by the + enum's type name if it is a top-level enum. Enum types have a String + method, and a Enum method to assist in message construction. + - Nested messages, groups and enums have type names prefixed with the name of + the surrounding message type. + - Extensions are given descriptor names that start with E_, + followed by an underscore-delimited list of the nested messages + that contain it (if any) followed by the CamelCased name of the + extension field itself. HasExtension, ClearExtension, GetExtension + and SetExtension are functions for manipulating extensions. + - Oneof field sets are given a single field in their message, + with distinguished wrapper types for each possible field value. + - Marshal and Unmarshal are functions to encode and decode the wire format. + +When the .proto file specifies `syntax="proto3"`, there are some differences: + + - Non-repeated fields of non-message type are values instead of pointers. + - Getters are only generated for message and oneof fields. + - Enum types do not get an Enum method. + +The simplest way to describe this is to see an example. +Given file test.proto, containing + + package example;

In those jurisdictions in + which the right to collect royalties through any statutory or + compulsory licensing scheme cannot be waived, the Licensor + reserves the exclusive right to collect such royalties for any + exercise by You of the rights granted under this License; + ii. Waivable Compulsory License Schemes. In those jurisdictions in + which the right to collect royalties through any statutory or + compulsory licensing scheme can be waived, the Licensor waives the + exclusive right to collect such royalties for any exercise by You + of the rights granted under this License; and, + iii. Voluntary License Schemes. The Licensor waives the right to + collect royalties, whether individually or, in the event that the + Licensor is a member of a collecting society that administers + voluntary licensing schemes, via that society, from any exercise + by You of the rights granted under this License. + +The above rights may be exercised in all media and formats whether now +known or hereafter devised. The above rights include the right to make +such modifications as are technically necessary to exercise the rights in +other media and formats. Subject to Section 8(f), all rights not expressly +granted by Licensor are hereby reserved. + +4. Restrictions. The license granted in Section 3 above is expressly made +subject to and limited by the following restrictions: + + a. You may Distribute or Publicly Perform the Work only under the terms + of this License. You must include a copy of, or the Uniform Resource + Identifier (URI) for, this License with every copy of the Work You + Distribute or Publicly Perform. You may not offer or impose any terms + on the Work that restrict the terms of this License or the ability of + the recipient of the Work to exercise the rights granted to that + recipient under the terms of the License. You may not sublicense the + Work. You must keep intact all notices that refer to this License and + to the disclaimer of warranties with every copy of the Work You + Distribute or Publicly Perform. When You Distribute or Publicly + Perform the Work, You may not impose any effective technological + measures on the Work that restrict the ability of a recipient of the + Work from You to exercise the rights granted to that recipient under + the terms of the License. This Section 4(a) applies to the Work as + incorporated in a Collection, but this does not require the Collection + apart from the Work itself to be made subject to the terms of this + License. If You create a Collection, upon notice from any Licensor You + must, to the extent practicable, remove from the Collection any credit + as required by Section 4(b), as requested. If You create an + Adaptation, upon notice from any Licensor You must, to the extent + practicable, remove from the Adaptation any credit as required by + Section 4(b), as requested. + b. If You Distribute, or Publicly Perform the Work or any Adaptations or + Collections, You must, unless a request has been made pursuant to + Section 4(a), keep intact all copyright notices for the Work and + provide, reasonable to the medium or means You are utilizing: (i) the + name of the Original Author (or pseudonym, if applicable) if supplied, + and/or if the Original Author and/or Licensor designate another party + or parties (e.g., a sponsor institute, publishing entity, journal) for + attribution ("Attribution Parties") in Licensor's copyright notice, + terms of service or by other reasonable means, the name of such party + or parties; (ii) the title of the Work if supplied; (iii) to the + extent reasonably practicable, the URI, if any, that Licensor + specifies to be associated with the Work, unless such URI does not + refer to the copyright notice or licensing information for the Work; + and (iv) , consistent with Section 3(b), in the case of an Adaptation, + a credit identifying the use of the Work in the Adaptation (e.g., + "French translation of the Work by Original Author," or "Screenplay + based on original Work by Original Author"). The credit required by + this Section 4 (b) may be implemented in any reasonable manner; + provided, however, that in the case of a Adaptation or Collection, at + a minimum such credit will appear, if a credit for all contributing + authors of the Adaptation or Collection appears, then as part of these + credits and in a manner at least as prominent as the credits for the + other contributing authors. For the avoidance of doubt, You may only + use the credit required by this Section for the purpose of attribution + in the manner set out above and, by exercising Your rights under this + License, You may not implicitly or explicitly assert or imply any + connection with, sponsorship or endorsement by the Original Author, + Licensor and/or Attribution Parties, as appropriate, of You or Your + use of the Work, without the separate, express prior written + permission of the Original Author, Licensor and/or Attribution + Parties. + c. Except as otherwise agreed in writing by the Licensor or as may be + otherwise permitted by applicable law, if You Reproduce, Distribute or + Publicly Perform the Work either by itself or as part of any + Adaptations or Collections, You must not distort, mutilate, modify or + take other derogatory action in relation to the Work which would be + prejudicial to the Original Author's honor or reputation. Licensor + agrees that in those jurisdictions (e.g. Japan), in which any exercise + of the right granted in Section 3(b) of this License (the right to + make Adaptations) would be deemed to be a distortion, mutilation, + modification or other derogatory action prejudicial to the Original + Author's honor and reputation, the Licensor will waive or not assert, + as appropriate, this Section, to the fullest extent permitted by the + applicable national law, to enable You to reasonably exercise Your + right under Section 3(b) of this License (right to make Adaptations) + but not otherwise. + +5. Representations, Warranties and Disclaimer + +UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR +OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY +KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, +INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY, +FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF +LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS, +WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION +OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU. + +6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE +LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR +ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES +ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS +BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + +7. Termination + + a. This License and the rights granted hereunder will terminate + automatically upon any breach by You of the terms of this License. + Individuals or entities who have received Adaptations or Collections + from You under this License, however, will not have their licenses + terminated provided such individuals or entities remain in full + compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will + survive any termination of this License. + b. Subject to the above terms and conditions, the license granted here is + perpetual (for the duration of the applicable copyright in the Work). + Notwithstanding the above, Licensor reserves the right to release the + Work under different license terms or to stop distributing the Work at + any time; provided, however that any such election will not serve to + withdraw this License (or any other license that has been, or is + required to be, granted under the terms of this License), and this + License will continue in full force and effect unless terminated as + stated above. + +8. Miscellaneous + + a. Each time You Distribute or Publicly Perform the Work or a Collection, + the Licensor offers to the recipient a license to the Work on the same + terms and conditions as the license granted to You under this License. + b. Each time You Distribute or Publicly Perform an Adaptation, Licensor + offers to the recipient a license to the original Work on the same + terms and conditions as the license granted to You under this License. + c. If any provision of this License is invalid or unenforceable under + applicable law, it shall not affect the validity or enforceability of + the remainder of the terms of this License, and without further action + by the parties to this agreement, such provision shall be reformed to + the minimum extent necessary to make such provision valid and + enforceable. + d. No term or provision of this License shall be deemed waived and no + breach consented to unless such waiver or consent shall be in writing + and signed by the party to be charged with such waiver or consent. + e. This License constitutes the entire agreement between the parties with + respect to the Work licensed here. There are no understandings, + agreements or representations with respect to the Work not specified + here. Licensor shall not be bound by any additional provisions that + may appear in any communication from You. This License may not be + modified without the mutual written agreement of the Licensor and You. + f. The rights granted under, and the subject matter referenced, in this + License were drafted utilizing the terminology of the Berne Convention + for the Protection of Literary and Artistic Works (as amended on + September 28, 1979), the Rome Convention of 1961, the WIPO Copyright + Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996 + and the Universal Copyright Convention (as revised on July 24, 1971). + These rights and subject matter take effect in the relevant + jurisdiction in which the License terms are sought to be enforced + according to the corresponding provisions of the implementation of + those treaty provisions in the applicable national law. If the + standard suite of rights granted under applicable copyright law + includes additional rights not granted under this License, such + additional rights are deemed to be included in the License; this + License is not intended to restrict the license of any rights under + applicable law. + + +Creative Commons Notice + + Creative Commons is not a party to this License, and makes no warranty + whatsoever in connection with the Work. Creative Commons will not be + liable to You or any party on any legal theory for any damages + whatsoever, including without limitation any general, special, + incidental or consequential damages arising in connection to this + license. Notwithstanding the foregoing two (2) sentences, if Creative + Commons has expressly identified itself as the Licensor hereunder, it + shall have all rights and obligations of Licensor. + + Except for the limited purpose of indicating to the public that the + Work is licensed under the CCPL, Creative Commons does not authorize + the use by either party of the trademark "Creative Commons" or any + related trademark or logo of Creative Commons without the prior + written consent of Creative Commons.

    • [[SQLITE_FCNTL_PERSIST_WAL]] -** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the -** persistent [WAL | Write Ahead Log] setting. By default, the auxiliary -** write ahead log and shared memory files used for transaction control -** are automatically deleted when the latest connection to the database -** closes. Setting persistent WAL mode causes those files to persist after -** close.

    • [[SQLITE_FCNTL_OVERWRITE]] -** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening -** a write transaction to indicate that, unless it is rolled back for some -** reason, the entire database file will be overwritten by the current -** transaction. This is used by VACUUM operations. -** -**
    • [[SQLITE_FCNTL_VFSNAME]] -** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of -** all [VFSes] in the VFS stack.

    • [[SQLITE_FCNTL_BUSYHANDLER]] -** ^The [SQLITE_FCNTL_BUSYHANDLER] -** file-control may be invoked by SQLite on the database file handle -** shortly after it is opened in order to provide a custom VFS with access -** to the connections busy-handler callback. The argument is of type (void **) -** - an array of two (void *) values. The first (void *) actually points -** to a function of type (int (*)(void *)). In order to invoke the connections -** busy-handler, this function should be invoked with the second (void *) in -** the array as the only argument. If it returns non-zero, then the operation -** should be retried. If it returns zero, the custom VFS should abandon the -** current operation. -** -**
    • [[SQLITE_FCNTL_TEMPFILENAME]] -** ^Application can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control -** to have SQLite generate a -** temporary filename using the same algorithm that is followed to generate -** temporary filenames for TEMP tables and other internal uses. The -** argument should be a char** which will be filled with the filename -** written into memory obtained from [sqlite3_malloc()]. The caller should -** invoke [sqlite3_free()] on the result to avoid a memory leak. -** -**
    • [[SQLITE_FCNTL_MMAP_SIZE]] -** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the -** maximum number of bytes that will be used for memory-mapped I/O. -** The argument is a pointer to a value of type sqlite3_int64 that -** is an advisory maximum number of bytes in the file to memory map. The -** pointer is overwritten with the old value. The limit is not changed if -** the value originally pointed to is negative, and so the current limit -** can be queried by passing in a pointer to a negative number. This -** file-control is used internally to implement [PRAGMA mmap_size]. -** -**
    • [[SQLITE_FCNTL_TRACE]] -** The [SQLITE_FCNTL_TRACE] file control provides advisory information -** to the VFS about what the higher layers of the SQLite stack are doing. -** This file control is used by some VFS activity tracing [shims]. -** The argument is a zero-terminated string. Higher layers in the -** SQLite stack may generate instances of this file control if -** the [SQLITE_USE_FCNTL_TRACE] compile-time option is enabled. -** -**
    • [[SQLITE_FCNTL_HAS_MOVED]] -** The [SQLITE_FCNTL_HAS_MOVED] file control interprets its argument as a -** pointer to an integer and it writes a boolean into that integer depending -** on whether or not the file has been renamed, moved, or deleted since it -** was first opened. -** -**
    • [[SQLITE_FCNTL_WIN32_SET_HANDLE]] -** The [SQLITE_FCNTL_WIN32_SET_HANDLE] opcode is used for debugging.

For example, if connection X is waiting for -** connection Y's transaction to be concluded, and similarly connection -** Y is waiting on connection X's transaction, then neither connection -** will proceed and the system may remain deadlocked indefinitely. -** -** To avoid this scenario, the sqlite3_unlock_notify() performs deadlock -** detection. ^If a given call to sqlite3_unlock_notify() would put the -** system in a deadlocked state, then SQLITE_LOCKED is returned and no -** unlock-notify callback is registered. The system is said to be in -** a deadlocked state if connection A has registered for an unlock-notify -** callback on the conclusion of connection B's transaction, and connection -** B has itself registered for an unlock-notify callback when connection -** A's transaction is concluded. ^Indirect deadlock is also detected, so -** the system is also considered to be deadlocked if connection B has -** registered for an unlock-notify callback on the conclusion of connection -** C's transaction, where connection C is waiting on connection A. ^Any -** number of levels of indirection are allowed. -** -** The "DROP TABLE" Exception -** -** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost -** always appropriate to call sqlite3_unlock_notify().

So we use only LockFile() and -** UnlockFile(). -** -** LockFile() prevents not just writing but also reading by other processes. -** A SHARED_LOCK is obtained by locking a single randomly-chosen -** byte out of a specific range of bytes. The lock byte is obtained at -** random so two separate readers can probably access the file at the -** same time, unless they are unlucky and choose the same lock byte. -** An EXCLUSIVE_LOCK is obtained by locking all bytes in the range. -** There can only be one writer. A RESERVED_LOCK is obtained by locking -** a single byte of the file that is designated as the reserved lock byte. -** A PENDING_LOCK is obtained by locking a designated byte different from -** the RESERVED_LOCK byte. -** -** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available, -** which means we can use reader/writer locks.

This leaves open the possiblity of having -** clients on win95, winNT, and unix all talking to the same shared file -** and all locking correctly. To do so would require that samba (or whatever -** tool is being used for file sharing) implements locks correctly between -** windows and unix. I'm guessing that isn't likely to happen, but by -** using the same locking range we are at least open to the possibility. -** -** Locking in windows is manditory. For this reason, we cannot store -** actual data in the bytes used for locking. The pager never allocates -** the pages involved in locking therefore. SHARED_SIZE is selected so -** that all locks will fit on a single page even at the minimum page size. -** PENDING_BYTE defines the beginning of the locks.

ANSI STD 1003.1 (1996) -** section 6.5.2.2 lines 483 through 490 specify that when a process -** sets or clears a lock, that operation overrides any prior locks set -** by the same process. It does not explicitly say so, but this implies -** that it overrides locks set by the same process using a different -** file descriptor. Consider this test case: -** -** int fd1 = open("./file1", O_RDWR|O_CREAT, 0644); -** int fd2 = open("./file2", O_RDWR|O_CREAT, 0644); -** -** Suppose ./file1 and ./file2 are really the same file (because -** one is a hard or symbolic link to the other) then if you set -** an exclusive lock on fd1, then try to get an exclusive lock -** on fd2, it works. I would have expected the second lock to -** fail since there was already a lock on the file due to fd1. -** But not so. Since both locks came from the same process, the -** second overrides the first, even though they were on different -** file descriptors opened on different file names. -** -** This means that we cannot use POSIX locks to synchronize file access -** among competing threads of the same process. POSIX locks will work fine -** to synchronize access for threads in separate processes, but not -** threads within the same process. -** -** To work around the problem, SQLite has to manage file locks internally -** on its own. Whenever a new database is opened, we have to find the -** specific inode of the database file (the inode is determined by the -** st_dev and st_ino fields of the stat structure that fstat() fills in) -** and check for locks already existing on that inode. When locks are -** created or removed, we have to look at our own internal record of the -** locks to see if another thread has previously set a lock on that same -** inode. -** -** (Aside: The use of inode numbers as unique IDs does not work on VxWorks. -** For VxWorks, we have to use the alternative unique ID system based on -** canonical filename and implemented in the previous division.) -** -** The sqlite3_file structure for POSIX is no longer just an integer file -** descriptor. It is now a structure that holds the integer file -** descriptor and a pointer to a structure that describes the internal -** locks on the corresponding inode. There is one locking structure -** per inode, so if the same inode is opened twice, both unixFile structures -** point to the same locking structure. The locking structure keeps -** a reference count (so we will know when to delete it) and a "cnt" -** field that tells us its internal lock status. cnt==0 means the -** file is unlocked. cnt==-1 means the file has an exclusive lock. -** cnt>0 means there are cnt shared locks on the file. -** -** Any attempt to lock or unlock a file first checks the locking -** structure. The fcntl() system call is only invoked to set a -** POSIX lock if the internal lock structure transitions between -** a locked and an unlocked state. -** -** But wait: there are yet more problems with POSIX advisory locks. -** -** If you close a file descriptor that points to a file that has locks, -** all locks on that file that are owned by the current process are -** released. To work around this problem, each unixInodeInfo object -** maintains a count of the number of pending locks on tha inode. -** When an attempt is made to close an unixFile, if there are -** other unixFile open on the same inode that are holding locks, the call -** to close() the file descriptor is deferred until all of the locks clear. -** The unixInodeInfo structure keeps a list of file descriptors that need to -** be closed and that list is walked (and cleared) when the last lock -** clears. -** -** Yet another problem: LinuxThreads do not play well with posix locks. -** -** Many older versions of linux use the LinuxThreads library which is -** not posix compliant. Under LinuxThreads, a lock created by thread -** A cannot be modified or overridden by a different thread B. -** Only thread A can modify the lock. Locking behavior is correct -** if the appliation uses the newer Native Posix Thread Library (NPTL) -** on linux - with NPTL a lock created by thread A can override locks -** in thread B. But there is no way to know at compile-time which -** threading library is being used.

Proxy locking is a -** meta-layer over top of the primitive locking implemented above. For -** this reason, the division that implements of proxy locking is deferred -** until late in the file (here) after all of the other I/O methods have -** been defined - so that the primitive locking methods are available -** as services to help with the implementation of proxy locking. -** -**** -** -** The default locking schemes in SQLite use byte-range locks on the -** database file to coordinate safe, concurrent access by multiple readers -** and writers [http://sqlite.org/lockingv3.html]. The five file locking -** states (UNLOCKED, PENDING, SHARED, RESERVED, EXCLUSIVE) are implemented -** as POSIX read & write locks over fixed set of locations (via fsctl), -** on AFP and SMB only exclusive byte-range locks are available via fsctl -** with _IOWR('z', 23, struct ByteRangeLockPB2) to track the same 5 states. -** To simulate a F_RDLCK on the shared range, on AFP a randomly selected -** address in the shared range is taken for a SHARED lock, the entire -** shared range is taken for an EXCLUSIVE lock): -** -** PENDING_BYTE 0x40000000 -** RESERVED_BYTE 0x40000001 -** SHARED_RANGE 0x40000002 -> 0x40000200 -** -** This works well on the local file system, but shows a nearly 100x -** slowdown in read performance on AFP because the AFP client disables -** the read cache when byte-range locks are present. Enabling the read -** cache exposes a cache coherency problem that is present on all OS X -** supported network file systems. NFS and AFP both observe the -** close-to-open semantics for ensuring cache coherency -** [http://nfs.sourceforge.net/#faq_a8], which does not effectively -** address the requirements for concurrent database access by multiple -** readers and writers -** [http://www.nabble.com/SQLite-on-NFS-cache-coherency-td15655701.html]. -** -** To address the performance and cache coherency issues, proxy file locking -** changes the way database access is controlled by limiting access to a -** single host at a time and moving file locks off of the database file -** and onto a proxy file on the local file system. -** -** -** Using proxy locks -** ----------------- -** -** C APIs -** -** sqlite3_file_control(db, dbname, SQLITE_SET_LOCKPROXYFILE, -** | ":auto:"); -** sqlite3_file_control(db, dbname, SQLITE_GET_LOCKPROXYFILE, &); -** -** -** SQL pragmas -** -** PRAGMA [database.]lock_proxy_file= | :auto: -** PRAGMA [database.]lock_proxy_file -** -** Specifying ":auto:" means that if there is a conch file with a matching -** host ID in it, the proxy path in the conch file will be used, otherwise -** a proxy path based on the user's temp dir -** (via confstr(_CS_DARWIN_USER_TEMP_DIR,...)) will be used and the -** actual proxy file name is generated from the name and path of the -** database file. For example: -** -** For database path "/Users/me/foo.db" -** The lock path will be "/sqliteplocks/_Users_me_foo.db:auto:") -** -** Once a lock proxy is configured for a database connection, it can not -** be removed, however it may be switched to a different proxy path via -** the above APIs (assuming the conch file is not being held by another -** connection or process). -** -** -** How proxy locking works -** ----------------------- -** -** Proxy file locking relies primarily on two new supporting files: -** -** * conch file to limit access to the database file to a single host -** at a time -** -** * proxy file to act as a proxy for the advisory locks normally -** taken on the database -** -** The conch file - to use a proxy file, sqlite must first "hold the conch" -** by taking an sqlite-style shared lock on the conch file, reading the -** contents and comparing the host's unique host ID (see below) and lock -** proxy path against the values stored in the conch. The conch file is -** stored in the same directory as the database file and the file name -** is patterned after the database file name as ".-conch". -** If the conch file does not exist, or it's contents do not match the -** host ID and/or proxy path, then the lock is escalated to an exclusive -** lock and the conch file contents is updated with the host ID and proxy -** path and the lock is downgraded to a shared lock again. If the conch -** is held by another process (with a shared lock), the exclusive lock -** will fail and SQLITE_BUSY is returned. -** -** The proxy file - a single-byte file used for all advisory file locks -** normally taken on the database file. This allows for safe sharing -** of the database file for multiple readers and writers on the same -** host (the conch ensures that they all use the same local lock file). -** -** Requesting the lock proxy does not immediately take the conch, it is -** only taken when the first request to lock database file is made. -** This matches the semantics of the traditional locking behavior, where -** opening a connection to a database file does not take a lock on it. -** The shared lock and an open file descriptor are maintained until -** the connection to the database is closed. -** -** The proxy file and the lock file are never deleted so they only need -** to be created the first time they are used. -** -** Configuration options -** --------------------- -** -** SQLITE_PREFER_PROXY_LOCKING -** -** Database files accessed on non-local file systems are -** automatically configured for proxy locking, lock files are -** named automatically using the same logic as -** PRAGMA lock_proxy_file=":auto:" -** -** SQLITE_PROXY_DEBUG -** -** Enables the logging of error messages during host id file -** retrieval and creation -** -** LOCKPROXYDIR -** -** Overrides the default directory used for lock proxy files that -** are named automatically via the ":auto:" setting -** -** SQLITE_DEFAULT_PROXYDIR_PERMISSIONS -** -** Permissions to use when creating a directory for storing the -** lock proxy files, only used when LOCKPROXYDIR is not set. -** -** -** As mentioned above, when compiled with SQLITE_PREFER_PROXY_LOCKING, -** setting the environment variable SQLITE_FORCE_PROXY_LOCKING to 1 will -** force proxy locking to be used for every database file opened, and 0 -** will force automatic proxy locking to be disabled for all database -** files (explicity calling the SQLITE_SET_LOCKPROXYFILE pragma or -** sqlite_file_control API is not affected by SQLITE_FORCE_PROXY_LOCKING). -*/ - -/* -** Proxy locking is only available on MacOSX -*/ -#if defined(__APPLE__) && SQLITE_ENABLE_LOCKING_STYLE - -/* -** The proxyLockingContext has the path and file structures for the remote -** and local proxy files in it -*/ -typedef struct proxyLockingContext proxyLockingContext;

Note in particular the content of freelist leaf -** pages can be changed arbitarily without effecting the logical equivalence -** of the database. -** -** (7) At any time, if any subset, including the empty set and the total set, -** of the unsynced changes to a rollback journal are removed and the -** journal is rolled back, the resulting database file will be logical -** equivalent to the database file at the beginning of the transaction. -** -** (8) When a transaction is rolled back, the xTruncate method of the VFS -** is called to restore the database file to the same size it was at -** the beginning of the transaction. (In some VFSes, the xTruncate -** method is a no-op, but that does not change the fact the SQLite will -** invoke it.) -** -** (9) Whenever the database file is modified, at least one bit in the range -** of bytes from 24 through 39 inclusive will be changed prior to releasing -** the EXCLUSIVE lock, thus signaling other connections on the same -** database to flush their caches. -** -** (10) The pattern of bits in bytes 24 through 39 shall not repeat in less -** than one billion transactions. -** -** (11) A database file is well-formed at the beginning and at the conclusion -** of every transaction. -** -** (12) An EXCLUSIVE lock is held on the database file when writing to -** the database file. -** -** (13) A SHARED lock is held on the database file while reading any -** content out of the database file. -** -******************************************************************************/ - -/* -** Macros for troubleshooting.

In WRITER_LOCKED state, all locks -** required to start a write-transaction are held, but no actual -** modifications to the cache or database have taken place. -** -** In rollback mode, a RESERVED or (if the transaction was opened with -** BEGIN EXCLUSIVE) EXCLUSIVE lock is obtained on the database file when -** moving to this state, but the journal file is not written to or opened -** to in this state. If the transaction is committed or rolled back while -** in WRITER_LOCKED state, all that is required is to unlock the database -** file. -** -** IN WAL mode, WalBeginWriteTransaction() is called to lock the log file. -** If the connection is running with locking_mode=exclusive, an attempt -** is made to obtain an EXCLUSIVE lock on the database file. -** -** * A write transaction is active. -** * If the connection is open in rollback-mode, a RESERVED or greater -** lock is held on the database file. -** * If the connection is open in WAL-mode, a WAL write transaction -** is open (i.e. sqlite3WalBeginWriteTransaction() has been successfully -** called). -** * The dbSize, dbOrigSize and dbFileSize variables are all valid. -** * The contents of the pager cache have not been modified. -** * The journal file may or may not be open. -** * Nothing (not even the first header) has been written to the journal. -** -** WRITER_CACHEMOD: -** -** A pager moves from WRITER_LOCKED state to this state when a page is -** first modified by the upper layer. In rollback mode the journal file -** is opened (if it is not already open) and a header written to the -** start of it. The database file on disk has not been modified. -** -** * A write transaction is active. -** * A RESERVED or greater lock is held on the database file. -** * The journal file is open and the first header has been written -** to it, but the header has not been synced to disk. -** * The contents of the page cache have been modified. -** -** WRITER_DBMOD: -** -** The pager transitions from WRITER_CACHEMOD into WRITER_DBMOD state -** when it modifies the contents of the database file. WAL connections -** never enter this state (since they do not modify the database file, -** just the log file). -** -** * A write transaction is active. -** * An EXCLUSIVE or greater lock is held on the database file. -** * The journal file is open and the first header has been written -** and synced to disk. -** * The contents of the page cache have been modified (and possibly -** written to disk). -** -** WRITER_FINISHED: -** -** It is not possible for a WAL connection to enter this state. -** -** A rollback-mode pager changes to WRITER_FINISHED state from WRITER_DBMOD -** state after the entire transaction has been successfully written into the -** database file. In this state the transaction may be committed simply -** by finalizing the journal file. Once in WRITER_FINISHED state, it is -** not possible to modify the database further. At this point, the upper -** layer must either commit or rollback the transaction. -** -** * A write transaction is active. -** * An EXCLUSIVE or greater lock is held on the database file. -** * All writing and syncing of journal and database data has finished. -** If no error occurred, all that remains is to finalize the journal to -** commit the transaction. If an error did occur, the caller will need -** to rollback the transaction. -** -** ERROR: -** -** The ERROR state is entered when an IO or disk-full error (including -** SQLITE_IOERR_NOMEM) occurs at a point in the code that makes it -** difficult to be sure that the in-memory pager state (cache contents, -** db size etc.) are consistent with the contents of the file-system. -** -** Temporary pager files may enter the ERROR state, but in-memory pagers -** cannot. -** -** For example, if an IO error occurs while performing a rollback, -** the contents of the page-cache may be left in an inconsistent state. -** At this point it would be dangerous to change back to READER state -** (as usually happens after a rollback). Any subsequent readers might -** report database corruption (due to the inconsistent cache), and if -** they upgrade to writers, they may inadvertently corrupt the database -** file. To avoid this hazard, the pager switches into the ERROR state -** instead of READER following such an error. -** -** Once it has entered the ERROR state, any attempt to use the pager -** to read or write data returns an error. Eventually, once all -** outstanding transactions have been abandoned, the pager is able to -** transition back to OPEN state, discarding the contents of the -** page-cache and any other in-memory state at the same time. Everything -** is reloaded from disk (and, if necessary, hot-journal rollback peformed) -** when a read-transaction is next opened on the pager (transitioning -** the pager into READER state). At that point the system has recovered -** from the error. -** -** Specifically, the pager jumps into the ERROR state if: -** -** 1. An error occurs while attempting a rollback. This happens in -** function sqlite3PagerRollback(). -** -** 2. An error occurs while attempting to finalize a journal file -** following a commit in function sqlite3PagerCommitPhaseTwo(). -** -** 3. An error occurs while attempting to write to the journal or -** database file in function pagerStress() in order to free up -** memory. -** -** In other cases, the error is returned to the b-tree layer. The b-tree -** layer then attempts a rollback operation. If the error condition -** persists, the pager enters the ERROR state via condition (1) above. -** -** Condition (3) is necessary because it can be triggered by a read-only -** statement executed within a transaction. In this case, if the error -** code were simply returned to the user, the b-tree layer would not -** automatically attempt a rollback, as it assumes that an error in a -** read-only statement cannot leave the pager in an internally inconsistent -** state. -** -** * The Pager.errCode variable is set to something other than SQLITE_OK. -** * There are one or more outstanding references to pages (after the -** last reference is dropped the pager should move back to OPEN state). -** * The pager is not an in-memory pager. -** -** -** Notes: -** -** * A pager is never in WRITER_DBMOD or WRITER_FINISHED state if the -** connection is open in WAL mode. A WAL connection is always in one -** of the first four states. -** -** * Normally, a connection open in exclusive mode is never in PAGER_OPEN -** state. There are two exceptions: immediately after exclusive-mode has -** been turned on (and before any read or write transactions are -** executed), and when the pager is leaving the "error state". -** -** * See also: assert_pager_state(). -*/ -#define PAGER_OPEN 0 -#define PAGER_READER 1 -#define PAGER_WRITER_LOCKED 2 -#define PAGER_WRITER_CACHEMOD 3 -#define PAGER_WRITER_DBMOD 4 -#define PAGER_WRITER_FINISHED 5 -#define PAGER_ERROR 6 - -/* -** The Pager.eLock variable is almost always set to one of the -** following locking-states, according to the lock currently held on -** the database file: NO_LOCK, SHARED_LOCK, RESERVED_LOCK or EXCLUSIVE_LOCK. -** This variable is kept up to date as locks are taken and released by -** the pagerLockDb() and pagerUnlockDb() wrappers. -** -** If the VFS xLock() or xUnlock() returns an error other than SQLITE_BUSY -** (i.e. one of the SQLITE_IOERR subtypes), it is not clear whether or not -** the operation was successful. In these circumstances pagerLockDb() and -** pagerUnlockDb() take a conservative approach - eLock is always updated -** when unlocking the file, and only updated when locking the file if the -** VFS call is successful. This way, the Pager.eLock variable may be set -** to a less exclusive (lower) value than the lock that is actually held -** at the system level, but it is never set to a more exclusive value. -** -** This is usually safe. If an xUnlock fails or appears to fail, there may -** be a few redundant xLock() calls or a lock may be held for longer than -** required, but nothing really goes wrong. -** -** The exception is when the database file is unlocked as the pager moves -** from ERROR to OPEN state. At this point there may be a hot-journal file -** in the file-system that needs to be rolled back (as part of a OPEN->SHARED -** transition, by the same pager or any other). If the call to xUnlock() -** fails at this point and the pager is left holding an EXCLUSIVE lock, this -** can confuse the call to xCheckReservedLock() call made later as part -** of hot-journal detection. -** -** xCheckReservedLock() is defined as returning true "if there is a RESERVED -** lock held by this process or any others". So xCheckReservedLock may -** return true because the caller itself is holding an EXCLUSIVE lock (but -** doesn't know it because of a previous error in xUnlock). If this happens -** a hot-journal may be mistaken for a journal being created by an active -** transaction in another process, causing SQLite to read from the database -** without rolling it back. -** -** To work around this, if a call to xUnlock() fails when unlocking the -** database in the ERROR state, Pager.eLock is set to UNKNOWN_LOCK. It -** is only changed back to a real locking state after a successful call -** to xLock(EXCLUSIVE). Also, the code to do the OPEN->SHARED state transition -** omits the check for a hot-journal if Pager.eLock is set to UNKNOWN_LOCK -** lock.

Since such -** databases always have Pager.exclusiveMode==1, this tricks the pager -** logic into thinking that it already has all the locks it will ever -** need (and no reason to release them). -** -** In some (obscure) circumstances, this variable may also be set to -** UNKNOWN_LOCK. See the comment above the #define of UNKNOWN_LOCK for -** details. -** -** changeCountDone -** -** This boolean variable is used to make sure that the change-counter -** (the 4-byte header field at byte offset 24 of the database file) is -** not updated more often than necessary. -** -** It is set to true when the change-counter field is updated, which -** can only happen if an exclusive lock is held on the database file. -** It is cleared (set to false) whenever an exclusive lock is -** relinquished on the database file. Each time a transaction is committed, -** The changeCountDone flag is inspected. If it is true, the work of -** updating the change-counter is omitted for the current transaction. -** -** This mechanism means that when running in exclusive mode, a connection -** need only update the change-counter once, for the first transaction -** committed. -** -** setMaster -** -** When PagerCommitPhaseOne() is called to commit a transaction, it may -** (or may not) specify a master-journal name to be written into the -** journal file before it is synced to disk. -** -** Whether or not a journal file contains a master-journal pointer affects -** the way in which the journal file is finalized after the transaction is -** committed or rolled back when running in "journal_mode=PERSIST" mode. -** If a journal file does not contain a master-journal pointer, it is -** finalized by overwriting the first journal header with zeroes. If -** it does contain a master-journal pointer the journal file is finalized -** by truncating it to zero bytes, just as if the connection were -** running in "journal_mode=truncate" mode. -** -** Journal files that contain master journal pointers cannot be finalized -** simply by overwriting the first journal-header with zeroes, as the -** master journal pointer could interfere with hot-journal rollback of any -** subsequently interrupted transaction that reuses the journal file. -** -** The flag is cleared as soon as the journal file is finalized (either -** by PagerCommitPhaseTwo or PagerRollback). If an IO error prevents the -** journal file from being successfully finalized, the setMaster flag -** is cleared anyway (and the pager will move to ERROR state). -** -** doNotSpill -** -** This variables control the behavior of cache-spills (calls made by -** the pcache module to the pagerStress() routine to write cached data -** to the file-system in order to free up memory). -** -** When bits SPILLFLAG_OFF or SPILLFLAG_ROLLBACK of doNotSpill are set, -** writing to the database from pagerStress() is disabled altogether. -** The SPILLFLAG_ROLLBACK case is done in a very obscure case that -** comes up during savepoint rollback that requires the pcache module -** to allocate a new page to prevent the journal file from being written -** while it is being traversed by code in pager_playback(). The SPILLFLAG_OFF -** case is a user preference. -** -** If the SPILLFLAG_NOSYNC bit is set, writing to the database from pagerStress() -** is permitted, but syncing the journal file is not. This flag is set -** by sqlite3PagerWrite() when the file-system sector-size is larger than -** the database page-size in order to prevent a journal sync from happening -** in between the journalling of two pages on the same sector. -** -** subjInMemory -** -** This is a boolean variable. If true, then any required sub-journal -** is opened as an in-memory journal file. If false, then in-memory -** sub-journals are only used for in-memory pager files. -** -** This variable is updated by the upper layer each time a new -** write-transaction is opened. -** -** dbSize, dbOrigSize, dbFileSize -** -** Variable dbSize is set to the number of pages in the database file. -** It is valid in PAGER_READER and higher states (all states except for -** OPEN and ERROR). -** -** dbSize is set based on the size of the database file, which may be -** larger than the size of the database (the value stored at offset -** 28 of the database header by the btree). If the size of the file -** is not an integer multiple of the page-size, the value stored in -** dbSize is rounded down (i.e. a 5KB file with 2K page-size has dbSize==2). -** Except, any file that is greater than 0 bytes in size is considered -** to have at least one page. (i.e. a 1KB file with 2K page-size leads -** to dbSize==1). -** -** During a write-transaction, if pages with page-numbers greater than -** dbSize are modified in the cache, dbSize is updated accordingly. -** Similarly, if the database is truncated using PagerTruncateImage(), -** dbSize is updated. -** -** Variables dbOrigSize and dbFileSize are valid in states -** PAGER_WRITER_LOCKED and higher. dbOrigSize is a copy of the dbSize -** variable at the start of the transaction. It is used during rollback, -** and to determine whether or not pages need to be journalled before -** being modified. -** -** Throughout a write-transaction, dbFileSize contains the size of -** the file on disk in pages. It is set to a copy of dbSize when the -** write-transaction is first opened, and updated when VFS calls are made -** to write or truncate the database file on disk. -** -** The only reason the dbFileSize variable is required is to suppress -** unnecessary calls to xTruncate() after committing a transaction. If, -** when a transaction is committed, the dbFileSize variable indicates -** that the database file is larger than the database image (Pager.dbSize), -** pager_truncate() is called. The pager_truncate() call uses xFilesize() -** to measure the database file on disk, and then truncates it if required. -** dbFileSize is not used when rolling back a transaction. In this case -** pager_truncate() is called unconditionally (which means there may be -** a call to xFilesize() that is not strictly required).

All changes to the database are recorded by writing -** frames into the WAL. Transactions commit when a frame is written that -** contains a commit marker. A single WAL can and usually does record -** multiple transactions. Periodically, the content of the WAL is -** transferred back into the database file in an operation called a -** "checkpoint". -** -** A single WAL file can be used multiple times. In other words, the -** WAL can fill up with frames and then be checkpointed and then new -** frames can overwrite the old ones. A WAL always grows from beginning -** toward the end. Checksums and counters attached to each frame are -** used to determine which frames within the WAL are valid and which -** are leftovers from prior checkpoints. -** -** The WAL header is 32 bytes in size and consists of the following eight -** big-endian 32-bit unsigned integer values: -** -** 0: Magic number. 0x377f0682 or 0x377f0683 -** 4: File format version. Currently 3007000 -** 8: Database page size. Example: 1024 -** 12: Checkpoint sequence number -** 16: Salt-1, random integer incremented with each checkpoint -** 20: Salt-2, a different random integer changing with each ckpt -** 24: Checksum-1 (first part of checksum for first 24 bytes of header). -** 28: Checksum-2 (second part of checksum for first 24 bytes of header). -** -** Immediately following the wal-header are zero or more frames. Each -** frame consists of a 24-byte frame-header followed by a bytes -** of page data. The frame-header is six big-endian 32-bit unsigned -** integer values, as follows: -** -** 0: Page number. -** 4: For commit records, the size of the database image in pages -** after the commit. For all other records, zero. -** 8: Salt-1 (copied from the header) -** 12: Salt-2 (copied from the header) -** 16: Checksum-1. -** 20: Checksum-2. -** -** A frame is considered valid if and only if the following conditions are -** true: -** -** (1) The salt-1 and salt-2 values in the frame-header match -** salt values in the wal-header -** -** (2) The checksum values in the final 8 bytes of the frame-header -** exactly match the checksum computed consecutively on the -** WAL header and the first 8 bytes and the content of all frames -** up to and including the current frame. -** -** The checksum is computed using 32-bit big-endian integers if the -** magic number in the first 4 bytes of the WAL is 0x377f0683 and it -** is computed using little-endian if the magic number is 0x377f0682. -** The checksum values are always stored in the frame header in a -** big-endian format regardless of which byte order is used to compute -** the checksum. The checksum is computed by interpreting the input as -** an even number of unsigned 32-bit integers: x[0] through x[N]. The -** algorithm used for the checksum is as follows: -** -** for i from 0 to n-1 step 2: -** s0 += x[i] + s1; -** s1 += x[i+1] + s0; -** endfor -** -** Note that s0 and s1 are both weighted checksums using fibonacci weights -** in reverse order (the largest fibonacci weight occurs on the first element -** of the sequence being summed.) The s1 value spans all 32-bit -** terms of the sequence whereas s0 omits the final term. -** -** On a checkpoint, the WAL is first VFS.xSync-ed, then valid content of the -** WAL is transferred into the database, then the database is VFS.xSync-ed. -** The VFS.xSync operations serve as write barriers - all writes launched -** before the xSync must complete before any write that launches after the -** xSync begins. -** -** After each checkpoint, the salt-1 value is incremented and the salt-2 -** value is randomized. This prevents old and new frames in the WAL from -** being considered valid at the same time and being checkpointing together -** following a crash. -** -** READER ALGORITHM -** -** To read a page from the database (call it page number P), a reader -** first checks the WAL to see if it contains page P. If so, then the -** last valid instance of page P that is a followed by a commit frame -** or is a commit frame itself becomes the value read. If the WAL -** contains no copies of page P that are valid and which are a commit -** frame or are followed by a commit frame, then page P is read from -** the database file. -** -** To start a read transaction, the reader records the index of the last -** valid frame in the WAL. The reader uses this recorded "mxFrame" value -** for all subsequent read operations. New transactions can be appended -** to the WAL, but as long as the reader uses its original mxFrame value -** and ignores the newly appended content, it will see a consistent snapshot -** of the database from a single point in time. This technique allows -** multiple concurrent readers to view different versions of the database -** content simultaneously. -** -** The reader algorithm in the previous paragraphs works correctly, but -** because frames for page P can appear anywhere within the WAL, the -** reader has to scan the entire WAL looking for page P frames. If the -** WAL is large (multiple megabytes is typical) that scan can be slow, -** and read performance suffers. To overcome this problem, a separate -** data structure called the wal-index is maintained to expedite the -** search for frames of a particular page. -** -** WAL-INDEX FORMAT -** -** Conceptually, the wal-index is shared memory, though VFS implementations -** might choose to implement the wal-index using a mmapped file. Because -** the wal-index is shared memory, SQLite does not support journal_mode=WAL -** on a network filesystem. All users of the database must be able to -** share memory. -** -** The wal-index is transient. After a crash, the wal-index can (and should -** be) reconstructed from the original WAL file. In fact, the VFS is required -** to either truncate or zero the header of the wal-index when the last -** connection to it closes. Because the wal-index is transient, it can -** use an architecture-specific format; it does not have to be cross-platform. -** Hence, unlike the database and WAL file formats which store all values -** as big endian, the wal-index can store multi-byte values in the native -** byte order of the host computer. -** -** The purpose of the wal-index is to answer this question quickly: Given -** a page number P and a maximum frame index M, return the index of the -** last frame in the wal before frame M for page P in the WAL, or return -** NULL if there are no frames for page P in the WAL prior to M. -** -** The wal-index consists of a header region, followed by an one or -** more index blocks. -** -** The wal-index header contains the total number of frames within the WAL -** in the mxFrame field. -** -** Each index block except for the first contains information on -** HASHTABLE_NPAGE frames. The first index block contains information on -** HASHTABLE_NPAGE_ONE frames. The values of HASHTABLE_NPAGE_ONE and -** HASHTABLE_NPAGE are selected so that together the wal-index header and -** first index block are the same size as all other index blocks in the -** wal-index. -** -** Each index block contains two sections, a page-mapping that contains the -** database page number associated with each wal frame, and a hash-table -** that allows readers to query an index block for a specific page number. -** The page-mapping is an array of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE -** for the first index block) 32-bit page numbers. The first entry in the -** first index-block contains the database page number corresponding to the -** first frame in the WAL file. The first entry in the second index block -** in the WAL file corresponds to the (HASHTABLE_NPAGE_ONE+1)th frame in -** the log, and so on. -** -** The last index block in a wal-index usually contains less than the full -** complement of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE) page-numbers, -** depending on the contents of the WAL file. This does not change the -** allocated size of the page-mapping array - the page-mapping array merely -** contains unused entries. -** -** Even without using the hash table, the last frame for page P -** can be found by scanning the page-mapping sections of each index block -** starting with the last index block and moving toward the first, and -** within each index block, starting at the end and moving toward the -** beginning. The first entry that equals P corresponds to the frame -** holding the content for that page. -** -** The hash table consists of HASHTABLE_NSLOT 16-bit unsigned integers. -** HASHTABLE_NSLOT = 2*HASHTABLE_NPAGE, and there is one entry in the -** hash table for each page number in the mapping section, so the hash -** table is never more than half full. The expected number of collisions -** prior to finding a match is 1. Each entry of the hash table is an -** 1-based index of an entry in the mapping section of the same -** index block. Let K be the 1-based index of the largest entry in -** the mapping section. (For index blocks other than the last, K will -** always be exactly HASHTABLE_NPAGE (4096) and for the last index block -** K will be (mxFrame%HASHTABLE_NPAGE).) Unused slots of the hash table -** contain a value of 0. -** -** To look for page P in the hash table, first compute a hash iKey on -** P as follows: -** -** iKey = (P * 383) % HASHTABLE_NSLOT -** -** Then start scanning entries of the hash table, starting with iKey -** (wrapping around to the beginning when the end of the hash table is -** reached) until an unused hash slot is found. Let the first unused slot -** be at index iUnused. (iUnused might be less than iKey if there was -** wrap-around.) Because the hash table is never more than half full, -** the search is guaranteed to eventually hit an unused entry. Let -** iMax be the value between iKey and iUnused, closest to iUnused, -** where aHash[iMax]==P.

Otherwise the iMax-th mapping entry of the -** current index block corresponds to the last entry that references -** page P. -** -** A hash search begins with the last index block and moves toward the -** first index block, looking for entries corresponding to page P. On -** average, only two or three slots in each index block need to be -** examined in order to either find the last entry for page P, or to -** establish that no such entry exists in the block. Each index block -** holds over 4000 entries. So two or three index blocks are sufficient -** to cover a typical 10 megabyte WAL file, assuming 1K pages. 8 or 10 -** comparisons (on average) suffice to either locate a frame in the -** WAL or to establish that the frame does not exist in the WAL. This -** is much faster than scanning the entire 10MB WAL. -** -** Note that entries are added in order of increasing K. Hence, one -** reader might be using some value K0 and a second reader that started -** at a later time (after additional transactions were added to the WAL -** and to the wal-index) might be using a different value K1, where K1>K0. -** Both readers can use the same hash table and mapping section to get -** the correct result. There may be entries in the hash table with -** K>K0 but to the first reader, those entries will appear to be unused -** slots in the hash table and so the first reader will get an answer as -** if no values greater than K0 had ever been inserted into the hash table -** in the first place - which is what reader one wants. Meanwhile, the -** second reader using K1 will see additional values that were inserted -** later, which is exactly what reader two wants. -** -** When a rollback occurs, the value of K is decreased.

Knuth, THE ART OF COMPUTER PROGRAMMING, Volume 3: -** "Sorting And Searching", pages 473-480. Addison-Wesley -** Publishing Company, Reading, Massachusetts. -** -** The basic idea is that each page of the file contains N database -** entries and N+1 pointers to subpages. -** -** ---------------------------------------------------------------- -** | Ptr(0) | Key(0) | Ptr(1) | Key(1) | ... | Key(N-1) | Ptr(N) | -** ---------------------------------------------------------------- -** -** All of the keys on the page that Ptr(0) points to have values less -** than Key(0). All of the keys on page Ptr(1) and its subpages have -** values greater than Key(0) and less than Key(1). All of the keys -** on Ptr(N) and its subpages have values greater than Key(N-1). And -** so forth. -** -** Finding a particular key requires reading O(log(M)) pages from the -** disk where M is the number of entries in the tree. -** -** In this implementation, a single file can hold one or more separate -** BTrees. Each BTree is identified by the index of its root page. The -** key and data for any entry are combined to form the "payload". A -** fixed amount of payload can be carried directly on the database -** page. If the payload is larger than the preset amount then surplus -** bytes are stored on overflow pages. The payload for an entry -** and the preceding pointer are combined to form a "Cell". Each -** page has a small header which contains the Ptr(N) pointer and other -** information such as the size of key and data. -** -** FORMAT DETAILS -** -** The file is divided into pages. The first page is called page 1, -** the second is page 2, and so forth. A page number of zero indicates -** "no such page". The page size can be any power of 2 between 512 and 65536. -** Each page can be either a btree page, a freelist page, an overflow -** page, or a pointer-map page. -** -** The first page is always a btree page. The first 100 bytes of the first -** page contain a special header (the "file header") that describes the file. -** The format of the file header is as follows: -** -** OFFSET SIZE DESCRIPTION -** 0 16 Header string: "SQLite format 3\000" -** 16 2 Page size in bytes. (1 means 65536) -** 18 1 File format write version -** 19 1 File format read version -** 20 1 Bytes of unused space at the end of each page -** 21 1 Max embedded payload fraction (must be 64) -** 22 1 Min embedded payload fraction (must be 32) -** 23 1 Min leaf payload fraction (must be 32) -** 24 4 File change counter -** 28 4 Reserved for future use -** 32 4 First freelist page -** 36 4 Number of freelist pages in the file -** 40 60 15 4-byte meta values passed to higher layers -** -** 40 4 Schema cookie -** 44 4 File format of schema layer -** 48 4 Size of page cache -** 52 4 Largest root-page (auto/incr_vacuum) -** 56 4 1=UTF-8 2=UTF16le 3=UTF16be -** 60 4 User version -** 64 4 Incremental vacuum mode -** 68 4 Application-ID -** 72 20 unused -** 92 4 The version-valid-for number -** 96 4 SQLITE_VERSION_NUMBER -** -** All of the integer values are big-endian (most significant byte first). -** -** The file change counter is incremented when the database is changed -** This counter allows other processes to know when the file has changed -** and thus when they need to flush their cache. -** -** The max embedded payload fraction is the amount of the total usable -** space in a page that can be consumed by a single cell for standard -** B-tree (non-LEAFDATA) tables. A value of 255 means 100%. The default -** is to limit the maximum cell size so that at least 4 cells will fit -** on one page. Thus the default max embedded payload fraction is 64. -** -** If the payload for a cell is larger than the max payload, then extra -** payload is spilled to overflow pages. Once an overflow page is allocated, -** as many bytes as possible are moved into the overflow pages without letting -** the cell size drop below the min embedded payload fraction. -** -** The min leaf payload fraction is like the min embedded payload fraction -** except that it applies to leaf nodes in a LEAFDATA tree. The maximum -** payload fraction for a LEAFDATA tree is always 100% (or 255) and it -** not specified in the header. -** -** Each btree pages is divided into three sections: The header, the -** cell pointer array, and the cell content area. Page 1 also has a 100-byte -** file header that occurs before the page header. -** -** |----------------| -** | file header | 100 bytes. Page 1 only. -** |----------------| -** | page header | 8 bytes for leaves. 12 bytes for interior nodes -** |----------------| -** | cell pointer | | 2 bytes per cell. Sorted order. -** | array | | Grows downward -** | | v -** |----------------| -** | unallocated | -** | space | -** |----------------| ^ Grows upwards -** | cell content | | Arbitrary order interspersed with freeblocks. -** | area | | and free space fragments. -** |----------------| -** -** The page headers looks like this: -** -** OFFSET SIZE DESCRIPTION -** 0 1 Flags. 1: intkey, 2: zerodata, 4: leafdata, 8: leaf -** 1 2 byte offset to the first freeblock -** 3 2 number of cells on this page -** 5 2 first byte of the cell content area -** 7 1 number of fragmented free bytes -** 8 4 Right child (the Ptr(N) value). Omitted on leaves. -** -** The flags define the format of this btree page. The leaf flag means that -** this page has no children. The zerodata flag means that this page carries -** only keys and no data. The intkey flag means that the key is a integer -** which is stored in the key size entry of the cell header rather than in -** the payload area. -** -** The cell pointer array begins on the first byte after the page header. -** The cell pointer array contains zero or more 2-byte numbers which are -** offsets from the beginning of the page to the cell content in the cell -** content area. The cell pointers occur in sorted order. The system strives -** to keep free space after the last cell pointer so that new cells can -** be easily added without having to defragment the page. -** -** Cell content is stored at the very end of the page and grows toward the -** beginning of the page. -** -** Unused space within the cell content area is collected into a linked list of -** freeblocks. Each freeblock is at least 4 bytes in size. The byte offset -** to the first freeblock is given in the header. Freeblocks occur in -** increasing order. Because a freeblock must be at least 4 bytes in size, -** any group of 3 or fewer unused bytes in the cell content area cannot -** exist on the freeblock chain. A group of 3 or fewer free bytes is called -** a fragment. The total number of bytes in all fragments is recorded. -** in the page header at offset 7. -** -** SIZE DESCRIPTION -** 2 Byte offset of the next freeblock -** 2 Bytes in this freeblock -** -** Cells are of variable length. Cells are stored in the cell content area at -** the end of the page. Pointers to the cells are in the cell pointer array -** that immediately follows the page header. Cells is not necessarily -** contiguous or in order, but cell pointers are contiguous and in order. -** -** Cell content makes use of variable length integers. A variable -** length integer is 1 to 9 bytes where the lower 7 bits of each -** byte are used. The integer consists of all bytes that have bit 8 set and -** the first byte with bit 8 clear. The most significant byte of the integer -** appears first. A variable-length integer may not be more than 9 bytes long. -** As a special case, all 8 bytes of the 9th byte are used as data. This -** allows a 64-bit integer to be encoded in 9 bytes. -** -** 0x00 becomes 0x00000000 -** 0x7f becomes 0x0000007f -** 0x81 0x00 becomes 0x00000080 -** 0x82 0x00 becomes 0x00000100 -** 0x80 0x7f becomes 0x0000007f -** 0x8a 0x91 0xd1 0xac 0x78 becomes 0x12345678 -** 0x81 0x81 0x81 0x81 0x01 becomes 0x10204081 -** -** Variable length integers are used for rowids and to hold the number of -** bytes of key and data in a btree cell. -** -** The content of a cell looks like this: -** -** SIZE DESCRIPTION -** 4 Page number of the left child.

The size of each PMA is roughly -** the same as the cache-size allowed for temporary databases. In order -** to allow the caller to extract keys from the sorter in sorted order, -** all PMAs currently stored on disk must be merged together. This comment -** describes the data structure used to do so. The structure supports -** merging any number of arrays in a single pass with no redundant comparison -** operations. -** -** The aIter[] array contains an iterator for each of the PMAs being merged. -** An aIter[] iterator either points to a valid key or else is at EOF. For -** the purposes of the paragraphs below, we assume that the array is actually -** N elements in size, where N is the smallest power of 2 greater to or equal -** to the number of iterators being merged. The extra aIter[] elements are -** treated as if they are empty (always at EOF). -** -** The aTree[] array is also N elements in size. The value of N is stored in -** the VdbeSorter.nTree variable. -** -** The final (N/2) elements of aTree[] contain the results of comparing -** pairs of iterator keys together. Element i contains the result of -** comparing aIter[2*i-N] and aIter[2*i-N+1]. Whichever key is smaller, the -** aTree element is set to the index of it. -** -** For the purposes of this comparison, EOF is considered greater than any -** other key value. If the keys are equal (only possible with two EOF -** values), it doesn't matter which index is stored. -** -** The (N/4) elements of aTree[] that precede the final (N/2) described -** above contains the index of the smallest of each block of 4 iterators. -** And so on. So that aTree[1] contains the index of the iterator that -** currently points to the smallest key value. aTree[0] is unused. -** -** Example: -** -** aIter[0] -> Banana -** aIter[1] -> Feijoa -** aIter[2] -> Elderberry -** aIter[3] -> Currant -** aIter[4] -> Grapefruit -** aIter[5] -> Apple -** aIter[6] -> Durian -** aIter[7] -> EOF -** -** aTree[] = { X, 5 0, 5 0, 3, 5, 6 } -** -** The current element is "Apple" (the value of the key indicated by -** iterator 5). When the Next() operation is invoked, iterator 5 will -** be advanced to the next key in its segment. Say the next key is -** "Eggplant": -** -** aIter[5] -> Eggplant -** -** The contents of aTree[] are updated first by comparing the new iterator -** 5 key to the current key of iterator 4 (still "Grapefruit"). The iterator -** 5 value is still smaller, so aTree[6] is set to 5. And so on up the tree. -** The value of iterator 6 - "Durian" - is now smaller than that of iterator -** 5, so aTree[3] is set to 6.

These statistics are made available to the query planner -** to help it make better decisions about how to perform queries. -** -** The following system tables are or have been supported: -** -** CREATE TABLE sqlite_stat1(tbl, idx, stat); -** CREATE TABLE sqlite_stat2(tbl, idx, sampleno, sample); -** CREATE TABLE sqlite_stat3(tbl, idx, nEq, nLt, nDLt, sample); -** CREATE TABLE sqlite_stat4(tbl, idx, nEq, nLt, nDLt, sample); -** -** Additional tables might be added in future releases of SQLite. -** The sqlite_stat2 table is not created or used unless the SQLite version -** is between 3.6.18 and 3.7.8, inclusive, and unless SQLite is compiled -** with SQLITE_ENABLE_STAT2. The sqlite_stat2 table is deprecated. -** The sqlite_stat2 table is superseded by sqlite_stat3, which is only -** created and used by SQLite versions 3.7.9 and later and with -** SQLITE_ENABLE_STAT3 defined. The functionality of sqlite_stat3 -** is a superset of sqlite_stat2. The sqlite_stat4 is an enhanced -** version of sqlite_stat3 and is only available when compiled with -** SQLITE_ENABLE_STAT4 and in SQLite versions 3.8.1 and later. It is -** not possible to enable both STAT3 and STAT4 at the same time. If they -** are both enabled, then STAT4 takes precedence. -** -** For most applications, sqlite_stat1 provides all the statisics required -** for the query planner to make good choices. -** -** Format of sqlite_stat1: -** -** There is normally one row per index, with the index identified by the -** name in the idx column. The tbl column is the name of the table to -** which the index belongs. In each such row, the stat column will be -** a string consisting of a list of integers. The first integer in this -** list is the number of rows in the index. (This is the same as the -** number of rows in the table, except for partial indices.) The second -** integer is the average number of rows in the index that have the same -** value in the first column of the index. The third integer is the average -** number of rows in the index that have the same value for the first two -** columns. The N-th integer (for N>1) is the average number of rows in -** the index which have the same value for the first N-1 columns. For -** a K-column index, there will be K+1 integers in the stat column. If -** the index is unique, then the last integer will be 1. -** -** The list of integers in the stat column can optionally be followed -** by the keyword "unordered". The "unordered" keyword, if it is present, -** must be separated from the last integer by a single space. If the -** "unordered" keyword is present, then the query planner assumes that -** the index is unordered and will not use the index for a range query. -** -** If the sqlite_stat1.idx column is NULL, then the sqlite_stat1.stat -** column contains a single integer which is the (estimated) number of -** rows in the table identified by sqlite_stat1.tbl. -** -** Format of sqlite_stat2: -** -** The sqlite_stat2 is only created and is only used if SQLite is compiled -** with SQLITE_ENABLE_STAT2 and if the SQLite version number is between -** 3.6.18 and 3.7.8. The "stat2" table contains additional information -** about the distribution of keys within an index. The index is identified by -** the "idx" column and the "tbl" column is the name of the table to which -** the index belongs. There are usually 10 rows in the sqlite_stat2 -** table for each index. -** -** The sqlite_stat2 entries for an index that have sampleno between 0 and 9 -** inclusive are samples of the left-most key value in the index taken at -** evenly spaced points along the index. Let the number of samples be S -** (10 in the standard build) and let C be the number of rows in the index. -** Then the sampled rows are given by: -** -** rownumber = (i*C*2 + C)/(S*2) -** -** For i between 0 and S-1. Conceptually, the index space is divided into -** S uniform buckets and the samples are the middle row from each bucket. -** -** The format for sqlite_stat2 is recorded here for legacy reference. This -** version of SQLite does not support sqlite_stat2. It neither reads nor -** writes the sqlite_stat2 table. This version of SQLite only supports -** sqlite_stat3. -** -** Format for sqlite_stat3: -** -** The sqlite_stat3 format is a subset of sqlite_stat4. Hence, the -** sqlite_stat4 format will be described first. Further information -** about sqlite_stat3 follows the sqlite_stat4 description. -** -** Format for sqlite_stat4: -** -** As with sqlite_stat2, the sqlite_stat4 table contains histogram data -** to aid the query planner in choosing good indices based on the values -** that indexed columns are compared against in the WHERE clauses of -** queries. -** -** The sqlite_stat4 table contains multiple entries for each index. -** The idx column names the index and the tbl column is the table of the -** index. If the idx and tbl columns are the same, then the sample is -** of the INTEGER PRIMARY KEY. The sample column is a blob which is the -** binary encoding of a key from the index. The nEq column is a -** list of integers. The first integer is the approximate number -** of entries in the index whose left-most column exactly matches -** the left-most column of the sample. The second integer in nEq -** is the approximate number of entries in the index where the -** first two columns match the first two columns of the sample. -** And so forth. nLt is another list of integers that show the approximate -** number of entries that are strictly less than the sample. The first -** integer in nLt contains the number of entries in the index where the -** left-most column is less than the left-most column of the sample. -** The K-th integer in the nLt entry is the number of index entries -** where the first K columns are less than the first K columns of the -** sample. The nDLt column is like nLt except that it contains the -** number of distinct entries in the index that are less than the -** sample. -** -** There can be an arbitrary number of sqlite_stat4 entries per index. -** The ANALYZE command will typically generate sqlite_stat4 tables -** that contain between 10 and 40 samples which are distributed across -** the key space, though not uniformly, and which include samples with -** large nEq values. -** -** Format for sqlite_stat3 redux: -** -** The sqlite_stat3 table is like sqlite_stat4 except that it only -** looks at the left-most column of the index. The sqlite_stat3.sample -** column contains the actual value of the left-most column instead -** of a blob encoding of the complete index key as is found in -** sqlite_stat4.sample. The nEq, nLt, and nDLt entries of sqlite_stat3 -** all contain just a single integer which is the same as the first -** integer in the equivalent columns in sqlite_stat4. -*/ -#ifndef SQLITE_OMIT_ANALYZE - -#if defined(SQLITE_ENABLE_STAT4) -# define IsStat4 1 -# define IsStat3 0 -#elif defined(SQLITE_ENABLE_STAT3) -# define IsStat4 0 -# define IsStat3 1 -#else -# define IsStat4 0 -# define IsStat3 0 -# undef SQLITE_STAT4_SAMPLES -# define SQLITE_STAT4_SAMPLES 1 -#endif -#define IsStat34 (IsStat3+IsStat4) /* 1 for STAT3 or STAT4. 0 otherwise */ - -/* -** This routine generates code that opens the sqlite_statN tables. -** The sqlite_stat1 table is always relevant. sqlite_stat2 is now -** obsolete. sqlite_stat3 and sqlite_stat4 are only opened when -** appropriate compile-time options are provided. -** -** If the sqlite_statN tables do not previously exist, it is created. -** -** Argument zWhere may be a pointer to a buffer containing a table name, -** or it may be a NULL pointer.

Thus a three-way join is an O(N^3) operation. But if -** the tables have indices and there are terms in the WHERE clause that -** refer to those indices, a complete table scan can be avoided and the -** code will run much faster.

The -** structures are like b+trees in layout, but are constructed from the -** bottom up in optimal fashion and are not updatable. Since trees -** are built from the bottom up, things will be described from the -** bottom up. -** -** -**** Varints **** -** The basic unit of encoding is a variable-length integer called a -** varint. We encode variable-length integers in little-endian order -** using seven bits * per byte as follows: -** -** KEY: -** A = 0xxxxxxx 7 bits of data and one flag bit -** B = 1xxxxxxx 7 bits of data and one flag bit -** -** 7 bits - A -** 14 bits - BA -** 21 bits - BBA -** and so on. -** -** This is similar in concept to how sqlite encodes "varints" but -** the encoding is not the same. SQLite varints are big-endian -** are are limited to 9 bytes in length whereas FTS3 varints are -** little-endian and can be up to 10 bytes in length (in theory). -** -** Example encodings: -** -** 1: 0x01 -** 127: 0x7f -** 128: 0x81 0x00 -** -** -**** Document lists **** -** A doclist (document list) holds a docid-sorted list of hits for a -** given term. Doclists hold docids and associated token positions. -** A docid is the unique integer identifier for a single document. -** A position is the index of a word within the document. The first -** word of the document has a position of 0. -** -** FTS3 used to optionally store character offsets using a compile-time -** option. But that functionality is no longer supported. -** -** A doclist is stored like this: -** -** array { -** varint docid; (delta from previous doclist) -** array { (position list for column 0) -** varint position; (2 more than the delta from previous position) -** } -** array { -** varint POS_COLUMN; (marks start of position list for new column) -** varint column; (index of new column) -** array { -** varint position; (2 more than the delta from previous position) -** } -** } -** varint POS_END; (marks end of positions for this document. -** } -** -** Here, array { X } means zero or more occurrences of X, adjacent in -** memory. A "position" is an index of a token in the token stream -** generated by the tokenizer. Note that POS_END and POS_COLUMN occur -** in the same logical place as the position element, and act as sentinals -** ending a position list array. POS_END is 0. POS_COLUMN is 1. -** The positions numbers are not stored literally but rather as two more -** than the difference from the prior position, or the just the position plus -** 2 for the first position. Example: -** -** label: A B C D E F G H I J K -** value: 123 5 9 1 1 14 35 0 234 72 0 -** -** The 123 value is the first docid. For column zero in this document -** there are two matches at positions 3 and 10 (5-2 and 9-2+3). The 1 -** at D signals the start of a new column; the 1 at E indicates that the -** new column is column number 1. There are two positions at 12 and 45 -** (14-2 and 35-2+12). The 0 at H indicate the end-of-document. The -** 234 at I is the delta to next docid (357). It has one position 70 -** (72-2) and then terminates with the 0 at K. -** -** A "position-list" is the list of positions for multiple columns for -** a single docid. A "column-list" is the set of positions for a single -** column. Hence, a position-list consists of one or more column-lists, -** a document record consists of a docid followed by a position-list and -** a doclist consists of one or more document records. -** -** A bare doclist omits the position information, becoming an -** array of varint-encoded docids. -** -**** Segment leaf nodes **** -** Segment leaf nodes store terms and doclists, ordered by term. Leaf -** nodes are written using LeafWriter, and read using LeafReader (to -** iterate through a single leaf node's data) and LeavesReader (to -** iterate through a segment's entire leaf layer). Leaf nodes have -** the format: -** -** varint iHeight; (height from leaf level, always 0) -** varint nTerm; (length of first term) -** char pTerm[nTerm]; (content of first term) -** varint nDoclist; (length of term's associated doclist) -** char pDoclist[nDoclist]; (content of doclist) -** array { -** (further terms are delta-encoded) -** varint nPrefix; (length of prefix shared with previous term) -** varint nSuffix; (length of unshared suffix) -** char pTermSuffix[nSuffix];(unshared suffix of next term) -** varint nDoclist; (length of term's associated doclist) -** char pDoclist[nDoclist]; (content of doclist) -** } -** -** Here, array { X } means zero or more occurrences of X, adjacent in -** memory. -** -** Leaf nodes are broken into blocks which are stored contiguously in -** the %_segments table in sorted order. This means that when the end -** of a node is reached, the next term is in the node with the next -** greater node id. -** -** New data is spilled to a new leaf node when the current node -** exceeds LEAF_MAX bytes (default 2048). New data which itself is -** larger than STANDALONE_MIN (default 1024) is placed in a standalone -** node (a leaf node with a single term and doclist). The goal of -** these settings is to pack together groups of small doclists while -** making it efficient to directly access large doclists. The -** assumption is that large doclists represent terms which are more -** likely to be query targets. -** -** TODO(shess) It may be useful for blocking decisions to be more -** dynamic. For instance, it may make more sense to have a 2.5k leaf -** node rather than splitting into 2k and .5k nodes. My intuition is -** that this might extend through 2x or 4x the pagesize. -** -** -**** Segment interior nodes **** -** Segment interior nodes store blockids for subtree nodes and terms -** to describe what data is stored by the each subtree. Interior -** nodes are written using InteriorWriter, and read using -** InteriorReader. InteriorWriters are created as needed when -** SegmentWriter creates new leaf nodes, or when an interior node -** itself grows too big and must be split. The format of interior -** nodes: -** -** varint iHeight; (height from leaf level, always >0) -** varint iBlockid; (block id of node's leftmost subtree) -** optional { -** varint nTerm; (length of first term) -** char pTerm[nTerm]; (content of first term) -** array { -** (further terms are delta-encoded) -** varint nPrefix; (length of shared prefix with previous term) -** varint nSuffix; (length of unshared suffix) -** char pTermSuffix[nSuffix]; (unshared suffix of next term) -** } -** } -** -** Here, optional { X } means an optional element, while array { X } -** means zero or more occurrences of X, adjacent in memory. -** -** An interior node encodes n terms separating n+1 subtrees. The -** subtree blocks are contiguous, so only the first subtree's blockid -** is encoded. The subtree at iBlockid will contain all terms less -** than the first term encoded (or all terms if no term is encoded). -** Otherwise, for terms greater than or equal to pTerm[i] but less -** than pTerm[i+1], the subtree for that term will be rooted at -** iBlockid+i. Interior nodes only store enough term data to -** distinguish adjacent children (if the rightmost term of the left -** child is "something", and the leftmost term of the right child is -** "wicked", only "w" is stored). -** -** New data is spilled to a new interior node at the same height when -** the current node exceeds INTERIOR_MAX bytes (default 2048). -** INTERIOR_MIN_TERMS (default 7) keeps large terms from monopolizing -** interior nodes and making the tree too skinny. The interior nodes -** at a given height are naturally tracked by interior nodes at -** height+1, and so on. -** -** -**** Segment directory **** -** The segment directory in table %_segdir stores meta-information for -** merging and deleting segments, and also the root node of the -** segment's tree. -** -** The root node is the top node of the segment's tree after encoding -** the entire segment, restricted to ROOT_MAX bytes (default 1024). -** This could be either a leaf node or an interior node. If the top -** node requires more than ROOT_MAX bytes, it is flushed to %_segments -** and a new root interior node is generated (which should always fit -** within ROOT_MAX because it only needs space for 2 varints, the -** height and the blockid of the previous root). -** -** The meta-information in the segment directory is: -** level - segment level (see below) -** idx - index within level -** - (level,idx uniquely identify a segment) -** start_block - first leaf node -** leaves_end_block - last leaf node -** end_block - last block (including interior nodes) -** root - contents of root node -** -** If the root node is a leaf node, then start_block, -** leaves_end_block, and end_block are all 0. -** -** -**** Segment merging **** -** To amortize update costs, segments are grouped into levels and -** merged in batches. Each increase in level represents exponentially -** more documents. -** -** New documents (actually, document updates) are tokenized and -** written individually (using LeafWriter) to a level 0 segment, with -** incrementing idx. When idx reaches MERGE_COUNT (default 16), all -** level 0 segments are merged into a single level 1 segment. Level 1 -** is populated like level 0, and eventually MERGE_COUNT level 1 -** segments are merged to a single level 2 segment (representing -** MERGE_COUNT^2 updates), and so on. -** -** A segment merge traverses all segments at a given level in -** parallel, performing a straightforward sorted merge. Since segment -** leaf nodes are written in to the %_segments table in order, this -** merge traverses the underlying sqlite disk structures efficiently. -** After the merge, all segment blocks from the merged level are -** deleted. -** -** MERGE_COUNT controls how often we merge segments. 16 seems to be -** somewhat of a sweet spot for insertion performance. 32 and 64 show -** very similar performance numbers to 16 on insertion, though they're -** a tiny bit slower (perhaps due to more overhead in merge-time -** sorting). 8 is about 20% slower than 16, 4 about 50% slower than -** 16, 2 about 66% slower than 16. -** -** At query time, high MERGE_COUNT increases the number of segments -** which need to be scanned and merged. For instance, with 100k docs -** inserted: -** -** MERGE_COUNT segments -** 16 25 -** 8 12 -** 4 10 -** 2 6 -** -** This appears to have only a moderate impact on queries for very -** frequent terms (which are somewhat dominated by segment merge -** costs), and infrequent and non-existent terms still seem to be fast -** even with many segments. -** -** TODO(shess) That said, it would be nice to have a better query-side -** argument for MERGE_COUNT of 16. Also, it is possible/likely that -** optimizations to things like doclist merging will swing the sweet -** spot around. -** -** -** -**** Handling of deletions and updates **** -** Since we're using a segmented structure, with no docid-oriented -** index into the term index, we clearly cannot simply update the term -** index when a document is deleted or updated. For deletions, we -** write an empty doclist (varint(docid) varint(POS_END)), for updates -** we simply write the new doclist. Segment merges overwrite older -** data for a particular docid with newer data, so deletes or updates -** will eventually overtake the earlier data and knock it out. The -** query logic likewise merges doclists so that newer data knocks out -** older data. -*/ - -/************** Include fts3Int.h in the middle of fts3.c ********************/ -/************** Begin file fts3Int.h *****************************************/ -/* -** 2009 Nov 12 -** -** The author disclaims copyright to this source code.

    • [[SQLITE_FCNTL_SIZE_HINT]] -** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS -** layer a hint of how large the database file will grow to be during the -** current transaction. This hint is not guaranteed to be accurate but it -** is often close. The underlying VFS might choose to preallocate database -** file space based on this hint in order to help writes to the database -** file run faster. -** -**
    • [[SQLITE_FCNTL_CHUNK_SIZE]] -** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS -** extends and truncates the database file in chunks of a size specified -** by the user. The fourth argument to [sqlite3_file_control()] should -** point to an integer (type int) containing the new chunk-size to use -** for the nominated database. Allocating database file space in large -** chunks (say 1MB at a time), may reduce file-system fragmentation and -** improve performance on some systems. -** -**
    • [[SQLITE_FCNTL_FILE_POINTER]] -** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer -** to the [sqlite3_file] object associated with a particular database -** connection. See the [sqlite3_file_control()] documentation for -** additional information. -** -**
    • [[SQLITE_FCNTL_SYNC_OMITTED]] -** No longer in use. -** -**
    • [[SQLITE_FCNTL_SYNC]] -** The [SQLITE_FCNTL_SYNC] opcode is generated internally by SQLite and -** sent to the VFS immediately before the xSync method is invoked on a -** database file descriptor. Or, if the xSync method is not invoked -** because the user has configured SQLite with -** [PRAGMA synchronous | PRAGMA synchronous=OFF] it is invoked in place -** of the xSync method. In most cases, the pointer argument passed with -** this file-control is NULL. However, if the database file is being synced -** as part of a multi-database commit, the argument points to a nul-terminated -** string containing the transactions master-journal file name. VFSes that -** do not need this signal should silently ignore this opcode. Applications -** should not call [sqlite3_file_control()] with this opcode as doing so may -** disrupt the operation of the specialized VFSes that do require it. -** -**
    • [[SQLITE_FCNTL_COMMIT_PHASETWO]] -** The [SQLITE_FCNTL_COMMIT_PHASETWO] opcode is generated internally by SQLite -** and sent to the VFS after a transaction has been committed immediately -** but before the database is unlocked. VFSes that do not need this signal -** should silently ignore this opcode. Applications should not call -** [sqlite3_file_control()] with this opcode as doing so may disrupt the -** operation of the specialized VFSes that do require it. -** -**
    • [[SQLITE_FCNTL_WIN32_AV_RETRY]] -** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic -** retry counts and intervals for certain disk I/O operations for the -** windows [VFS] in order to provide robustness in the presence of -** anti-virus programs. By default, the windows VFS will retry file read, -** file write, and file delete operations up to 10 times, with a delay -** of 25 milliseconds before the first retry and with the delay increasing -** by an additional 25 milliseconds with each subsequent retry. This -** opcode allows these two values (10 retries and 25 milliseconds of delay) -** to be adjusted. The values are changed for all database connections -** within the same process. The argument is a pointer to an array of two -** integers where the first integer i the new retry count and the second -** integer is the delay. If either integer is negative, then the setting -** is not changed but instead the prior value of that setting is written -** into the array entry, allowing the current retry settings to be -** interrogated. The zDbName parameter is ignored. -** -**
    • [[SQLITE_FCNTL_PERSIST_WAL]] -** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the -** persistent [WAL | Write Ahead Log] setting. By default, the auxiliary -** write ahead log and shared memory files used for transaction control -** are automatically deleted when the latest connection to the database -** closes. Setting persistent WAL mode causes those files to persist after -** close. Persisting the files is useful when other processes that do not -** have write permission on the directory containing the database file want -** to read the database file, as the WAL and shared memory files must exist -** in order for the database to be readable. The fourth parameter to -** [sqlite3_file_control()] for this opcode should be a pointer to an integer. -** That integer is 0 to disable persistent WAL mode or 1 to enable persistent -** WAL mode. If the integer is -1, then it is overwritten with the current -** WAL persistence setting. -** -**
    • [[SQLITE_FCNTL_POWERSAFE_OVERWRITE]] -** ^The [SQLITE_FCNTL_POWERSAFE_OVERWRITE] opcode is used to set or query the -** persistent "powersafe-overwrite" or "PSOW" setting. The PSOW setting -** determines the [SQLITE_IOCAP_POWERSAFE_OVERWRITE] bit of the -** xDeviceCharacteristics methods. The fourth parameter to -** [sqlite3_file_control()] for this opcode should be a pointer to an integer. -** That integer is 0 to disable zero-damage mode or 1 to enable zero-damage -** mode. If the integer is -1, then it is overwritten with the current -** zero-damage mode setting. -** -**
    • [[SQLITE_FCNTL_OVERWRITE]] -** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening -** a write transaction to indicate that, unless it is rolled back for some -** reason, the entire database file will be overwritten by the current -** transaction. This is used by VACUUM operations. -** -**
    • [[SQLITE_FCNTL_VFSNAME]] -** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of -** all [VFSes] in the VFS stack. The names are of all VFS shims and the -** final bottom-level VFS are written into memory obtained from -** [sqlite3_malloc()] and the result is stored in the char* variable -** that the fourth parameter of [sqlite3_file_control()] points to. -** The caller is responsible for freeing the memory when done. As with -** all file-control actions, there is no guarantee that this will actually -** do anything. Callers should initialize the char* variable to a NULL -** pointer in case this file-control is not implemented. This file-control -** is intended for diagnostic use only. -** -**
    • [[SQLITE_FCNTL_PRAGMA]] -** ^Whenever a [PRAGMA] statement is parsed, an [SQLITE_FCNTL_PRAGMA] -** file control is sent to the open [sqlite3_file] object corresponding -** to the database file to which the pragma statement refers. ^The argument -** to the [SQLITE_FCNTL_PRAGMA] file control is an array of -** pointers to strings (char**) in which the second element of the array -** is the name of the pragma and the third element is the argument to the -** pragma or NULL if the pragma has no argument. ^The handler for an -** [SQLITE_FCNTL_PRAGMA] file control can optionally make the first element -** of the char** argument point to a string obtained from [sqlite3_mprintf()] -** or the equivalent and that string will become the result of the pragma or -** the error message if the pragma fails. ^If the -** [SQLITE_FCNTL_PRAGMA] file control returns [SQLITE_NOTFOUND], then normal -** [PRAGMA] processing continues. ^If the [SQLITE_FCNTL_PRAGMA] -** file control returns [SQLITE_OK], then the parser assumes that the -** VFS has handled the PRAGMA itself and the parser generates a no-op -** prepared statement. ^If the [SQLITE_FCNTL_PRAGMA] file control returns -** any result code other than [SQLITE_OK] or [SQLITE_NOTFOUND], that means -** that the VFS encountered an error while handling the [PRAGMA] and the -** compilation of the PRAGMA fails with an error. ^The [SQLITE_FCNTL_PRAGMA] -** file control occurs at the beginning of pragma statement analysis and so -** it is able to override built-in [PRAGMA] statements. -** -**
    • [[SQLITE_FCNTL_BUSYHANDLER]] -** ^The [SQLITE_FCNTL_BUSYHANDLER] -** file-control may be invoked by SQLite on the database file handle -** shortly after it is opened in order to provide a custom VFS with access -** to the connections busy-handler callback. The argument is of type (void **) -** - an array of two (void *) values. The first (void *) actually points -** to a function of type (int (*)(void *)). In order to invoke the connections -** busy-handler, this function should be invoked with the second (void *) in -** the array as the only argument. If it returns non-zero, then the operation -** should be retried. If it returns zero, the custom VFS should abandon the -** current operation. -** -**
    • [[SQLITE_FCNTL_TEMPFILENAME]] -** ^Application can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control -** to have SQLite generate a -** temporary filename using the same algorithm that is followed to generate -** temporary filenames for TEMP tables and other internal uses. The -** argument should be a char** which will be filled with the filename -** written into memory obtained from [sqlite3_malloc()]. The caller should -** invoke [sqlite3_free()] on the result to avoid a memory leak. -** -**
    • [[SQLITE_FCNTL_MMAP_SIZE]] -** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the -** maximum number of bytes that will be used for memory-mapped I/O. -** The argument is a pointer to a value of type sqlite3_int64 that -** is an advisory maximum number of bytes in the file to memory map. The -** pointer is overwritten with the old value. The limit is not changed if -** the value originally pointed to is negative, and so the current limit -** can be queried by passing in a pointer to a negative number. This -** file-control is used internally to implement [PRAGMA mmap_size]. -** -**
    • [[SQLITE_FCNTL_TRACE]] -** The [SQLITE_FCNTL_TRACE] file control provides advisory information -** to the VFS about what the higher layers of the SQLite stack are doing. -** This file control is used by some VFS activity tracing [shims]. -** The argument is a zero-terminated string. Higher layers in the -** SQLite stack may generate instances of this file control if -** the [SQLITE_USE_FCNTL_TRACE] compile-time option is enabled. -** -**
    • [[SQLITE_FCNTL_HAS_MOVED]] -** The [SQLITE_FCNTL_HAS_MOVED] file control interprets its argument as a -** pointer to an integer and it writes a boolean into that integer depending -** on whether or not the file has been renamed, moved, or deleted since it -** was first opened. -** -**
    • [[SQLITE_FCNTL_WIN32_SET_HANDLE]] -** The [SQLITE_FCNTL_WIN32_SET_HANDLE] opcode is used for debugging. This -** opcode causes the xFileControl method to swap the file handle with the one -** pointed to by the pArg argument. This capability is used during testing -** and only needs to be supported when SQLITE_TEST is defined. -** -**

The SQLITE_OPEN_EXCLUSIVE flag, when paired with the -** SQLITE_OPEN_CREATE, is used to indicate that file should always -** be created, and that it is an error if it already exists. -** It is not used to indicate the file should be opened -** for exclusive access. -** -** ^At least szOsFile bytes of memory are allocated by SQLite -** to hold the [sqlite3_file] structure passed as the third -** argument to xOpen.

See "[URI filenames]" for additional -** information. -** -** URI filenames are parsed according to RFC 3986. ^If the URI contains an -** authority, then it must be either an empty string or the string -** "localhost". ^If the authority is not an empty string or "localhost", an -** error is returned to the caller. ^The fragment component of a URI, if -** present, is ignored. -** -** ^SQLite uses the path component of the URI as the name of the disk file -** which contains the database. ^If the path begins with a '/' character, -** then it is interpreted as an absolute path. ^If the path does not begin -** with a '/' (meaning that the authority section is omitted from the URI) -** then the path is interpreted as a relative path. -** ^On windows, the first component of an absolute path -** is a drive specification (e.g. "C:"). -** -** [[core URI query parameters]] -** The query component of a URI may contain parameters that are interpreted -** either by SQLite itself, or by a [VFS | custom VFS implementation]. -** SQLite interprets the following three query parameters: -** -**
      -**
    • vfs: ^The "vfs" parameter may be used to specify the name of -** a VFS object that provides the operating system interface that should -** be used to access the database file on disk. ^If this option is set to -** an empty string the default VFS object is used. ^Specifying an unknown -** VFS is an error. ^If sqlite3_open_v2() is used and the vfs option is -** present, then the VFS specified by the option takes precedence over -** the value passed as the fourth parameter to sqlite3_open_v2(). -** -**
    • mode: ^(The mode parameter may be set to either "ro", "rw", -** "rwc", or "memory". Attempting to set it to any other value is -** an error)^. -** ^If "ro" is specified, then the database is opened for read-only -** access, just as if the [SQLITE_OPEN_READONLY] flag had been set in the -** third argument to sqlite3_open_v2(). ^If the mode option is set to -** "rw", then the database is opened for read-write (but not create) -** access, as if SQLITE_OPEN_READWRITE (but not SQLITE_OPEN_CREATE) had -** been set. ^Value "rwc" is equivalent to setting both -** SQLITE_OPEN_READWRITE and SQLITE_OPEN_CREATE. ^If the mode option is -** set to "memory" then a pure [in-memory database] that never reads -** or writes from disk is used. ^It is an error to specify a value for -** the mode parameter that is less restrictive than that specified by -** the flags passed in the third parameter to sqlite3_open_v2(). -** -**
    • cache: ^The cache parameter may be set to either "shared" or -** "private". ^Setting it to "shared" is equivalent to setting the -** SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to -** sqlite3_open_v2(). ^Setting the cache parameter to "private" is -** equivalent to setting the SQLITE_OPEN_PRIVATECACHE bit. -** ^If sqlite3_open_v2() is used and the "cache" parameter is present in -** a URI filename, its value overrides any behavior requested by setting -** SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag. -** -**
    • psow: ^The psow parameter may be "true" (or "on" or "yes" or -** "1") or "false" (or "off" or "no" or "0") to indicate that the -** [powersafe overwrite] property does or does not apply to the -** storage media on which the database file resides. ^The psow query -** parameter only works for the built-in unix and Windows VFSes. -** -**
    • nolock: ^The nolock parameter is a boolean query parameter -** which if set disables file locking in rollback journal modes. This -** is useful for accessing a database on a filesystem that does not -** support locking. Caution: Database corruption might result if two -** or more processes write to the same database and any one of those -** processes uses nolock=1. -** -**
    • immutable: ^The immutable parameter is a boolean query -** parameter that indicates that the database file is stored on -** read-only media. ^When immutable is set, SQLite assumes that the -** database file cannot be changed, even by a process with higher -** privilege, and so the database is opened read-only and all locking -** and change detection is disabled. Caution: Setting the immutable -** property on a database file that does in fact change can result -** in incorrect query results and/or [SQLITE_CORRUPT] errors. -** See also: [SQLITE_IOCAP_IMMUTABLE]. -** -**
    -** -** ^Specifying an unknown parameter in the query component of a URI is not an -** error. Future versions of SQLite might understand additional query -** parameters. See "[query parameters with special meaning to SQLite]" for -** additional information. -** -** [[URI filename examples]]

The first argument passed to -** an unlock-notify callback is a pointer to an array of void* pointers, -** and the second is the number of entries in the array. -** -** When a blocking connections transaction is concluded, there may be -** more than one blocked connection that has registered for an unlock-notify -** callback. ^If two or more such blocked connections have specified the -** same callback function, then instead of invoking the callback function -** multiple times, it is invoked once with the set of void* context pointers -** specified by the blocked connections bundled together into an array. -** This gives the application an opportunity to prioritize any actions -** related to the set of unblocked database connections. -** -** Deadlock Detection -** -** Assuming that after registering for an unlock-notify callback a -** database waits for the callback to be issued before taking any further -** action (a reasonable assumption), then using this API may cause the -** application to deadlock. For example, if connection X is waiting for -** connection Y's transaction to be concluded, and similarly connection -** Y is waiting on connection X's transaction, then neither connection -** will proceed and the system may remain deadlocked indefinitely. -** -** To avoid this scenario, the sqlite3_unlock_notify() performs deadlock -** detection. ^If a given call to sqlite3_unlock_notify() would put the -** system in a deadlocked state, then SQLITE_LOCKED is returned and no -** unlock-notify callback is registered. The system is said to be in -** a deadlocked state if connection A has registered for an unlock-notify -** callback on the conclusion of connection B's transaction, and connection -** B has itself registered for an unlock-notify callback when connection -** A's transaction is concluded. ^Indirect deadlock is also detected, so -** the system is also considered to be deadlocked if connection B has -** registered for an unlock-notify callback on the conclusion of connection -** C's transaction, where connection C is waiting on connection A. ^Any -** number of levels of indirection are allowed. -** -** The "DROP TABLE" Exception -** -** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost -** always appropriate to call sqlite3_unlock_notify().

Application of Additional Terms - - You may choose to offer, and to charge a fee for, warranty, support, - indemnity or liability obligations to one or more recipients of Covered - Software. However, You may do so only on Your own behalf, and not on behalf - of any Contributor. You must make it absolutely clear that any such - warranty, support, indemnity, or liability obligation is offered by You - alone, and You hereby agree to indemnify every Contributor for any - liability incurred by such Contributor as a result of warranty, support, - indemnity or liability terms You offer. You may include additional - disclaimers of warranty and limitations of liability specific to any - jurisdiction. - -4. Inability to Comply Due to Statute or Regulation - - If it is impossible for You to comply with any of the terms of this License - with respect to some or all of the Covered Software due to statute, judicial - order, or regulation then You must: (a) comply with the terms of this License - to the maximum extent possible; and (b) describe the limitations and the code - they affect.

This limitation of liability - shall not apply to liability for death or personal injury resulting from such - party’s negligence to the extent applicable law prohibits such limitation. - Some jurisdictions do not allow the exclusion or limitation of incidental or - consequential damages, so this exclusion and limitation may not apply to You. - -8. Litigation - - Any litigation relating to this License may be brought only in the courts of - a jurisdiction where the defendant maintains its principal place of business - and such litigation shall be governed by laws of that jurisdiction, without - reference to its conflict-of-law provisions.

Its main purpose is to facilitate dealing -with JWE/JWS messages when testing or debugging. - -## Usage - -The utility includes the subcommands `encrypt`, `decrypt`, `sign`, `verify` and -`expand`. Examples for each command can be found below. - -Algorithms are selected via the `--alg` and `--enc` flags, which influence the -`alg` and `enc` headers in respectively. For JWE, `--alg` specifies the key -managment algorithm (e.g. `RSA-OAEP`) and `--enc` specifies the content -encryption (e.g. `A128GCM`). For JWS, `--alg` specifies the signature algorithm -(e.g. `PS256`). - -Input and output files can be specified via the `--in` and `--out` flags. -Either flag can be omitted, in which case `jose-util` uses stdin/stdout for -input/output respectively. By default each command will output a compact -message, but it's possible to get the full serialization by supplying the -`--full` flag. - -Keys are specified via the `--key` flag. Supported key types are naked RSA/EC -keys and X.509 certificates with embedded RSA/EC keys. Keys must be in PEM -or DER formats. - -## Examples - -### Encrypt - -Takes a plaintext as input, encrypts, and prints the encrypted message. - - jose-util encrypt -k public-key.pem --alg RSA-OAEP --enc A128GCM - -### Decrypt - -Takes an encrypted message (JWE) as input, decrypts, and prints the plaintext. - - jose-util decrypt -k private-key.pem - -### Sign - -Takes a payload as input, signs it, and prints the signed message with the embedded payload. - - jose-util sign -k private-key.pem --alg PS256 - -### Verify - -Reads a signed message (JWS), verifies it, and extracts the payload. - - jose-util verify -k public-key.pem - -### Expand - -Expands a compact message to the full serialization format. -

-Package validator implements value validations for structs and individual fields based on tags. - -It has the following **unique** features: - -- Cross Field and Cross Struct validations. -- Slice, Array and Map diving, which allows any or all levels of a multidimensional field to be validated. -- Handles type interface by determining it's underlying type prior to validation. - -Installation ------------- - -Use go get. - - go get gopkg.in/bluesuncorp/validator.v5 - -or to update - - go get -u gopkg.in/bluesuncorp/validator.v5 - -Then import the validator package into your own code. - - import "gopkg.in/bluesuncorp/validator.v5" - -Usage and documentation ------- - -Please see http://godoc.org/gopkg.in/bluesuncorp/validator.v5 for detailed usage docs. - -##### Example: -```go -package main -

fmt.Println(err.Value) // output: 135 - - // or if you prefer you can use the Flatten function - // NOTE: I find this usefull when using a more hard static approach of checking field errors. - // The above, is best for passing to some generic code to say parse the errors. i.e. I pass errs - // to a routine which loops through the errors, creates and translates the error message into the - // users locale and returns a map of map[string]string // field and error which I then use - // within the HTML rendering. - - flat := errs.Flatten() - fmt.Println(flat) // output: map[Age:Field validation for "Age" failed on the "lte" tag Addresses[0].Address.City:Field validation for "City" failed on the "required" tag] - err = flat["Addresses[0].Address.City"] - fmt.Println(err.Field) // output: City - fmt.Println(err.Tag) // output: required - fmt.Println(err.Kind) // output: string - fmt.Println(err.Type) // output: string - fmt.Println(err.Param) // output: - fmt.Println(err.Value) // output: - - // from here you can create your own error messages in whatever language you wish - return - } - - // save user to database -} -``` -

This can also be combined with 'and' for example - ( Usage: omitempty,rgb|rgba) - - structonly - When a field that is a nest struct in encountered and contains this flag - any validation on the nested struct such as "required" will be run, but - none of the nested struct fields will be validated. This is usefull if - inside of you program you know the struct will be valid, but need to - verify it has been assigned. - - exists - Is a special tag without a validation function attached. It is used when a field - is a Pointer, Interface or Invalid and you wish to validate that it exists. - Example: want to ensure a bool exists if you define the bool as a pointer and - use exists it will ensure there is a value; couldn't use required as it would - fail when the bool was false. exists will fail is the value is a Pointer, Interface - or Invalid and is nil. (Usage: exists) - - omitempty - Allows conditional validation, for example if a field is not set with - a value (Determined by the required validator) then other validation - such as min or max won't run, but if a value is set validation will run. - (Usage: omitempty) - - dive - This tells the validator to dive into a slice, array or map and validate that - level of the slice, array or map with the validation tags that follow. - Multidimensional nesting is also supported, each level you wish to dive will - require another dive tag. (Usage: dive) - Example: [][]string with validation tag "gt=0,dive,len=1,dive,required" - gt=0 will be applied to [] - len=1 will be applied to []string - required will be applied to string - Example2: [][]string with validation tag "gt=0,dive,dive,required" - gt=0 will be applied to [] - []string will be spared validation - required will be applied to string - NOTE: in Example2 if the required validation failed, but all others passed - the hierarchy of FieldError's in the middle with have their IsPlaceHolder field - set to true. If a FieldError has IsSliceOrMap=true or IsMap=true then the - FieldError is a Slice or Map field and if IsPlaceHolder=true then contains errors - within its SliceOrArrayErrs or MapErrs fields. - - required - This validates that the value is not the data types default zero value. - For numbers ensures value is not zero. For strings ensures value is - not "". For slices, maps, pointers, interfaces, channels and functions - ensures the value is not nil. - (Usage: required) - - len - For numbers, max will ensure that the value is - equal to the parameter given. For strings, it checks that - the string length is exactly that number of characters. For slices, - arrays, and maps, validates the number of items. (Usage: len=10) - - max - For numbers, max will ensure that the value is - less than or equal to the parameter given.

For strings, it checks that - the string length is at least that number of characters. For slices, - arrays, and maps, validates the number of items. (Usage: min=10) - - eq - For strings & numbers, eq will ensure that the value is - equal to the parameter given. For slices, arrays, and maps, - validates the number of items.

validator implements value validations for structs and individual fields based on tags. + +It has the following **unique** features: + +- Cross Field and Cross Struct validations by using validation tags or custom validators. +- Slice, Array and Map diving, which allows any or all levels of a multidimensional field to be validated. +- Handles type interface by determining it's underlying type prior to validation. +- Handles custom field types such as sql driver Valuer see [Valuer](https://golang.org/src/database/sql/driver/types.go?s=1210:1293#L29) +- Alias validation tags, which allows for mapping of several validations to a single tag for easier defining of validations on structs +- Extraction of custom defined Field Name e.g. can specify to extract the JSON name while validating and have it available in the resulting FieldError + +Installation +------------ + +Use go get. + + go get gopkg.in/go-playground/validator.v8 + +or to update + + go get -u gopkg.in/go-playground/validator.v8 + +Then import the validator package into your own code. + + import "gopkg.in/go-playground/validator.v8" + +Error Return Value +------- + +Validation functions return type error + +They return type error to avoid the issue discussed in the following, where err is always != nil: + +* http://stackoverflow.com/a/29138676/3158232 +* https://github.com/go-playground/validator/issues/134 + +validator only returns nil or ValidationErrors as type error; so in you code all you need to do +is check if the error returned is not nil, and if it's not type cast it to type ValidationErrors +like so: + +```go +err := validate.Struct(mystruct) +validationErrors := err.(validator.ValidationErrors) + ``` + +Usage and documentation +------ +

Cross-Field and Cross-Struct validation for nested structs +and has the ability to dive into arrays and maps of any type. + +Why not a better error message? +Because this library intends for you to handle your own error messages. + +Why should I handle my own errors? +Many reasons.

Example: + + // Structure + func customFunc(v *Validate, topStruct reflect.Value, currentStructOrField reflect.Value, field reflect.Value, fieldType reflect.Type, fieldKind reflect.Kind, param string) bool { + + if whatever { + return false + } + + return true + } + + validate.RegisterValidation("custom tag name", customFunc) + // NOTES: using the same tag name as an existing function + // will overwrite the existing one + +Cross-Field Validation + +Cross-Field Validation can be done via the following tags: + - eqfield + - nefield + - gtfield + - gtefield + - ltfield + - ltefield + - eqcsfield + - necsfield + - gtcsfield + - ftecsfield + - ltcsfield + - ltecsfield + +If, however, some custom cross-field validation is required, it can be done +using a custom validation. + +Why not just have cross-fields validation tags (i.e. only eqcsfield and not +eqfield)? + +The reason is efficiency. If you want to check a field within the same struct +"eqfield" only has to find the field on the same struct (1 level). But, if we +used "eqcsfield" it could be multiple levels down. Example: + + type Inner struct { + StartDate time.Time + } + + type Outer struct { + InnerStructField *Inner + CreatedAt time.Time `validate:"ltecsfield=InnerStructField.StartDate"` + } + + now := time.Now() + + inner := &Inner{ + StartDate: now, + } + + outer := &Outer{ + InnerStructField: inner, + CreatedAt: now, + } + + errs := validate.Struct(outer) + + // NOTE: when calling validate.Struct(val) topStruct will be the top level struct passed + // into the function + // when calling validate.FieldWithValue(val, field, tag) val will be + // whatever you pass, struct, field... + // when calling validate.Field(field, tag) val will be nil + +Multiple Validators + +Multiple validators on a field will process in the order defined.

If you wish to +have a comma included within the parameter (i.e. excludesall=,) you will need to +use the UTF-8 hex representation 0x2C, which is replaced in the code as a comma, +so the above will become excludesall=0x2C. + + type Test struct { + Field `validate:"excludesall=,"` // BAD! Do not include a comma. + Field `validate:"excludesall=0x2C"` // GOOD! Use the UTF-8 hex representation. + } + +Pipe ("|") is the default separator of validation tags. If you wish to +have a pipe included within the parameter i.e. excludesall=| you will need to +use the UTF-8 hex representation 0x7C, which is replaced in the code as a pipe, +so the above will become excludesall=0x7C + + type Test struct { + Field `validate:"excludesall=|"` // BAD! Do not include a a pipe! + Field `validate:"excludesall=0x7C"` // GOOD! Use the UTF-8 hex representation. + } + + +Baked In Validators and Tags + +Here is a list of the current built in validators: + + +Skip Field + +Tells the validation to skip this struct field; this is particularily +handy in ignoring embedded structs from being validated. (Usage: -) + Usage: - + + +Or Operator + +This is the 'or' operator allowing multiple validators to be used and +accepted. (Usage: rbg|rgba) <-- this would allow either rgb or rgba +colors to be accepted. This can also be combined with 'and' for example +( Usage: omitempty,rgb|rgba) + + Usage: | + +StructOnly + +When a field that is a nested struct is encountered, and contains this flag +any validation on the nested struct will be run, but none of the nested +struct fields will be validated. This is usefull if inside of you program +you know the struct will be valid, but need to verify it has been assigned. +NOTE: only "required" and "omitempty" can be used on a struct itself. + + Usage: structonly + +NoStructLevel + +Same as structonly tag except that any struct level validations will not run. + + Usage: nostructlevel + +Exists + +Is a special tag without a validation function attached. It is used when a field +is a Pointer, Interface or Invalid and you wish to validate that it exists. +Example: want to ensure a bool exists if you define the bool as a pointer and +use exists it will ensure there is a value; couldn't use required as it would +fail when the bool was false. exists will fail is the value is a Pointer, Interface +or Invalid and is nil. + + Usage: exists + +Omit Empty + +Allows conditional validation, for example if a field is not set with +a value (Determined by the "required" validator) then other validation +such as min or max won't run, but if a value is set validation will run. + + Usage: omitempty + +Dive + +This tells the validator to dive into a slice, array or map and validate that +level of the slice, array or map with the validation tags that follow. +Multidimensional nesting is also supported, each level you wish to dive will +require another dive tag. + + Usage: dive + +Example #1 + + [][]string with validation tag "gt=0,dive,len=1,dive,required" + // gt=0 will be applied to [] + // len=1 will be applied to []string + // required will be applied to string + +Example #2 + + [][]string with validation tag "gt=0,dive,dive,required" + // gt=0 will be applied to [] + // []string will be spared validation + // required will be applied to string + +Required + +This validates that the value is not the data types default zero value. +For numbers ensures value is not zero. For strings ensures value is +not "". For slices, maps, pointers, interfaces, channels and functions +ensures the value is not nil. + + Usage: required + +Length + +For numbers, max will ensure that the value is +equal to the parameter given. For strings, it checks that +the string length is exactly that number of characters. For slices, +arrays, and maps, validates the number of items. + + Usage: len=10 + +Maximum + +For numbers, max will ensure that the value is +less than or equal to the parameter given. For strings, it checks +that the string length is at most that number of characters. For +slices, arrays, and maps, validates the number of items. + + Usage: max=10 + +Mininum + +For numbers, min will ensure that the value is +greater or equal to the parameter given. For strings, it checks that +the string length is at least that number of characters. For slices, +arrays, and maps, validates the number of items. + + Usage: min=10 + +Equals + +For strings & numbers, eq will ensure that the value is +equal to the parameter given. For slices, arrays, and maps, +validates the number of items. + + Usage: eq=10 + +Not Equal + +For strings & numbers, eq will ensure that the value is not +equal to the parameter given. For slices, arrays, and maps, +validates the number of items. + + Usage: eq=10 + +Greater Than + +For numbers, this will ensure that the value is greater than the +parameter given. For strings, it checks that the string length +is greater than that number of characters. For slices, arrays +and maps it validates the number of items. + +Example #1 + + Usage: gt=10 + +Example #2 (time.Time) + +For time.Time ensures the time value is greater than time.Now.UTC(). + + Usage: gt + +Greater Than or Equal + +Same as 'min' above. Kept both to make terminology with 'len' easier. + + +Example #1 + + Usage: gte=10 + +Example #2 (time.Time) + +For time.Time ensures the time value is greater than or equal to time.Now.UTC(). + + Usage: gte + +Less Than + +For numbers, this will ensure that the value is less than the parameter given. +For strings, it checks that the string length is less than that number of +characters. For slices, arrays, and maps it validates the number of items. + +Example #1 + + Usage: lt=10 + +Example #2 (time.Time) +For time.Time ensures the time value is less than time.Now.UTC(). + + Usage: lt + +Less Than or Equal + +Same as 'max' above.

Everything after the +dive tag is not reported as the alias tag. Also, the "ActualTag" in the before +case will be the actual tag within the alias that failed. + +Here is a list of the current built in alias tags: + + "iscolor" + alias is "hexcolor|rgb|rgba|hsl|hsla" (Usage: iscolor) + +Validator notes: + + regex + a regex validator won't be added because commas and = signs can be part + of a regex which conflict with the validation definitions. Although + workarounds can be made, they take away from using pure regex's. + Furthermore it's quick and dirty but the regex's become harder to + maintain and are not reusable, so it's as much a programming philosiphy + as anything. + + In place of this new validator functions should be created; a regex can + be used within the validator function and even be precompiled for better + efficiency within regexes.go. + + And the best reason, you can submit a pull request and we can keep on + adding to the validation library of this package! + +Panics + +This package panics when bad input is provided, this is by design, bad code like +that should not make it to production. + + type Test struct { + TestField string `validate:"nonexistantfunction=1"` + } + + t := &Test{ +

Please see the LICENSE file for details. - - -Example -------- - -```Go -package main - -import ( - "fmt" - "log" - - "gopkg.in/yaml.v1" -) - -var data = ` -a: Easy! -b: - c: 2 - d: [3, 4] -` - -type T struct { - A string - B struct{C int; D []int ",flow"} -} - -func main() { - t := T{} - - err := yaml.Unmarshal([]byte(data), &t) - if err != nil { - log.Fatalf("error: %v", err) - } - fmt.Printf("--- t:\n%v\n\n", t) - - d, err := yaml.Marshal(&t) - if err != nil { - log.Fatalf("error: %v", err) - } - fmt.Printf("--- t dump:\n%s\n\n", string(d)) - - m := make(map[interface{}]interface{}) - - err = yaml.Unmarshal([]byte(data), &m) - if err != nil { - log.Fatalf("error: %v", err) - } - fmt.Printf("--- m:\n%v\n\n", m) - - d, err = yaml.Marshal(&m) - if err != nil { - log.Fatalf("error: %v", err) - } - fmt.Printf("--- m dump:\n%s\n\n", string(d)) -} -``` - -This example will generate the following output: - -``` ---- t: -{Easy! {2 [3 4]}} - ---- t dump: -a: Easy! -b: - c: 2 - d: [3, 4] - - ---- m: -map[a:Easy! b:map[c:2 d:[3 4]]] - ---- m dump: -a: Easy! -b: - c: 2 - d: - - 3 - - 4 -``` - diff --git a/vendor/gopkg.in/yaml.v1/apic.go b/vendor/gopkg.in/yaml.v1/apic.go deleted file mode 100644 index 95ec014e8..000000000 --- a/vendor/gopkg.in/yaml.v1/apic.go +++ /dev/null @@ -1,742 +0,0 @@ -package yaml -

We start with the list -// of all the tokens produced by the Scanner together with short descriptions. -// -// Now, tokens: -// -// STREAM-START(encoding) # The stream start. -// STREAM-END # The stream end. -// VERSION-DIRECTIVE(major,minor) # The '%YAML' directive. -// TAG-DIRECTIVE(handle,prefix) # The '%TAG' directive. -// DOCUMENT-START # '---' -// DOCUMENT-END # '...' -// BLOCK-SEQUENCE-START # Indentation increase denoting a block -// BLOCK-MAPPING-START # sequence or a block mapping. -// BLOCK-END # Indentation decrease. -// FLOW-SEQUENCE-START # '[' -// FLOW-SEQUENCE-END # ']' -// BLOCK-SEQUENCE-START # '{' -// BLOCK-SEQUENCE-END # '}' -// BLOCK-ENTRY # '-' -// FLOW-ENTRY # ',' -// KEY # '?' or nothing (simple keys). -// VALUE # ':' -// ALIAS(anchor) # '*anchor' -// ANCHOR(anchor) # '&anchor' -// TAG(handle,suffix) # '!handle!suffix' -// SCALAR(value,style) # A scalar. -// -// The following two tokens are "virtual" tokens denoting the beginning and the -// end of the stream: -// -// STREAM-START(encoding) -// STREAM-END -// -// We pass the information about the input stream encoding with the -// STREAM-START token. -// -// The next two tokens are responsible for tags: -// -// VERSION-DIRECTIVE(major,minor) -// TAG-DIRECTIVE(handle,prefix) -// -// Example: -// -// %YAML 1.1 -// %TAG ! !foo -// %TAG !yaml! tag:yaml.org,2002: -// --- -// -// The correspoding sequence of tokens: -// -// STREAM-START(utf-8) -// VERSION-DIRECTIVE(1,1) -// TAG-DIRECTIVE("!","!foo") -// TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:") -// DOCUMENT-START -// STREAM-END -// -// Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole -// line. -// -// The document start and end indicators are represented by: -// -// DOCUMENT-START -// DOCUMENT-END -// -// Note that if a YAML stream contains an implicit document (without '---' -// and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be -// produced. -// -// In the following examples, we present whole documents together with the -// produced tokens. -// -// 1. An implicit document: -// -// 'a scalar' -// -// Tokens: -// -// STREAM-START(utf-8) -// SCALAR("a scalar",single-quoted) -// STREAM-END -// -// 2. An explicit document: -// -// --- -// 'a scalar' -// ... -// -// Tokens: -// -// STREAM-START(utf-8) -// DOCUMENT-START -// SCALAR("a scalar",single-quoted) -// DOCUMENT-END -// STREAM-END -// -// 3. Several documents in a stream: -// -// 'a scalar' -// --- -// 'another scalar' -// --- -// 'yet another scalar' -// -// Tokens: -// -// STREAM-START(utf-8) -// SCALAR("a scalar",single-quoted) -// DOCUMENT-START -// SCALAR("another scalar",single-quoted) -// DOCUMENT-START -// SCALAR("yet another scalar",single-quoted) -// STREAM-END -// -// We have already introduced the SCALAR token above. The following tokens are -// used to describe aliases, anchors, tag, and scalars: -// -// ALIAS(anchor) -// ANCHOR(anchor) -// TAG(handle,suffix) -// SCALAR(value,style) -// -// The following series of examples illustrate the usage of these tokens: -// -// 1. A recursive sequence: -// -// &A [ *A ] -// -// Tokens: -// -// STREAM-START(utf-8) -// ANCHOR("A") -// FLOW-SEQUENCE-START -// ALIAS("A") -// FLOW-SEQUENCE-END -// STREAM-END -// -// 2. A tagged scalar: -// -// !!float "3.14" # A good approximation. -// -// Tokens: -// -// STREAM-START(utf-8) -// TAG("!!","float") -// SCALAR("3.14",double-quoted) -// STREAM-END -// -// 3. Various scalar styles: -// -// --- # Implicit empty plain scalars do not produce tokens. -// --- a plain scalar -// --- 'a single-quoted scalar' -// --- "a double-quoted scalar" -// --- |- -// a literal scalar -// --- >- -// a folded -// scalar -// -// Tokens: -// -// STREAM-START(utf-8) -// DOCUMENT-START -// DOCUMENT-START -// SCALAR("a plain scalar",plain) -// DOCUMENT-START -// SCALAR("a single-quoted scalar",single-quoted) -// DOCUMENT-START -// SCALAR("a double-quoted scalar",double-quoted) -// DOCUMENT-START -// SCALAR("a literal scalar",literal) -// DOCUMENT-START -// SCALAR("a folded scalar",folded) -// STREAM-END -// -// Now it's time to review collection-related tokens. We will start with -// flow collections: -// -// FLOW-SEQUENCE-START -// FLOW-SEQUENCE-END -// FLOW-MAPPING-START -// FLOW-MAPPING-END -// FLOW-ENTRY -// KEY -// VALUE -// -// The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and -// FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}' -// correspondingly. FLOW-ENTRY represent the ',' indicator. Finally the -// indicators '?' and ':', which are used for denoting mapping keys and values, -// are represented by the KEY and VALUE tokens. -// -// The following examples show flow collections: -// -// 1. A flow sequence: -// -// [item 1, item 2, item 3] -// -// Tokens: -// -// STREAM-START(utf-8) -// FLOW-SEQUENCE-START -// SCALAR("item 1",plain) -// FLOW-ENTRY -// SCALAR("item 2",plain) -// FLOW-ENTRY -// SCALAR("item 3",plain) -// FLOW-SEQUENCE-END -// STREAM-END -// -// 2. A flow mapping: -// -// { -// a simple key: a value, # Note that the KEY token is produced. -// ? a complex key: another value, -// } -// -// Tokens: -// -// STREAM-START(utf-8) -// FLOW-MAPPING-START -// KEY -// SCALAR("a simple key",plain) -// VALUE -// SCALAR("a value",plain) -// FLOW-ENTRY -// KEY -// SCALAR("a complex key",plain) -// VALUE -// SCALAR("another value",plain) -// FLOW-ENTRY -// FLOW-MAPPING-END -// STREAM-END -// -// A simple key is a key which is not denoted by the '?' indicator. Note that -// the Scanner still produce the KEY token whenever it encounters a simple key. -// -// For scanning block collections, the following tokens are used (note that we -// repeat KEY and VALUE here): -// -// BLOCK-SEQUENCE-START -// BLOCK-MAPPING-START -// BLOCK-END -// BLOCK-ENTRY -// KEY -// VALUE -// -// The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation -// increase that precedes a block collection (cf. the INDENT token in Python). -// The token BLOCK-END denote indentation decrease that ends a block collection -// (cf. the DEDENT token in Python). However YAML has some syntax pecularities -// that makes detections of these tokens more complex. -// -// The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators -// '-', '?', and ':' correspondingly. -// -// The following examples show how the tokens BLOCK-SEQUENCE-START, -// BLOCK-MAPPING-START, and BLOCK-END are emitted by the Scanner: -// -// 1. Block sequences: -// -// - item 1 -// - item 2 -// - -// - item 3.1 -// - item 3.2 -// - -// key 1: value 1 -// key 2: value 2 -// -// Tokens: -// -// STREAM-START(utf-8) -// BLOCK-SEQUENCE-START -// BLOCK-ENTRY -// SCALAR("item 1",plain) -// BLOCK-ENTRY -// SCALAR("item 2",plain) -// BLOCK-ENTRY -// BLOCK-SEQUENCE-START -// BLOCK-ENTRY -// SCALAR("item 3.1",plain) -// BLOCK-ENTRY -// SCALAR("item 3.2",plain) -// BLOCK-END -// BLOCK-ENTRY -// BLOCK-MAPPING-START -// KEY -// SCALAR("key 1",plain) -// VALUE -// SCALAR("value 1",plain) -// KEY -// SCALAR("key 2",plain) -// VALUE -// SCALAR("value 2",plain) -// BLOCK-END -// BLOCK-END -// STREAM-END -// -// 2. Block mappings: -// -// a simple key: a value # The KEY token is produced here. -// ? a complex key -// : another value -// a mapping: -// key 1: value 1 -// key 2: value 2 -// a sequence: -// - item 1 -// - item 2 -// -// Tokens: -// -// STREAM-START(utf-8) -// BLOCK-MAPPING-START -// KEY -// SCALAR("a simple key",plain) -// VALUE -// SCALAR("a value",plain) -// KEY -// SCALAR("a complex key",plain) -// VALUE -// SCALAR("another value",plain) -// KEY -// SCALAR("a mapping",plain) -// BLOCK-MAPPING-START -// KEY -// SCALAR("key 1",plain) -// VALUE -// SCALAR("value 1",plain) -// KEY -// SCALAR("key 2",plain) -// VALUE -// SCALAR("value 2",plain) -// BLOCK-END -// KEY -// SCALAR("a sequence",plain) -// VALUE -// BLOCK-SEQUENCE-START -// BLOCK-ENTRY -// SCALAR("item 1",plain) -// BLOCK-ENTRY -// SCALAR("item 2",plain) -// BLOCK-END -// BLOCK-END -// STREAM-END -// -// YAML does not always require to start a new block collection from a new -// line. If the current line contains only '-', '?', and ':' indicators, a new -// block collection may start at the current line. The following examples -// illustrate this case: -// -// 1. Collections in a sequence: -// -// - - item 1 -// - item 2 -// - key 1: value 1 -// key 2: value 2 -// - ? complex key -// : complex value -// -// Tokens: -// -// STREAM-START(utf-8) -// BLOCK-SEQUENCE-START -// BLOCK-ENTRY -// BLOCK-SEQUENCE-START -// BLOCK-ENTRY -// SCALAR("item 1",plain) -// BLOCK-ENTRY -// SCALAR("item 2",plain) -// BLOCK-END -// BLOCK-ENTRY -// BLOCK-MAPPING-START -// KEY -// SCALAR("key 1",plain) -// VALUE -// SCALAR("value 1",plain) -// KEY -// SCALAR("key 2",plain) -// VALUE -// SCALAR("value 2",plain) -// BLOCK-END -// BLOCK-ENTRY -// BLOCK-MAPPING-START -// KEY -// SCALAR("complex key") -// VALUE -// SCALAR("complex value") -// BLOCK-END -// BLOCK-END -// STREAM-END -// -// 2.

This hint is not guaranteed to be accurate but it +** is often close. The underlying VFS might choose to preallocate database +** file space based on this hint in order to help writes to the database +** file run faster. +** +**
    • [[SQLITE_FCNTL_CHUNK_SIZE]] +** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS +** extends and truncates the database file in chunks of a size specified +** by the user. The fourth argument to [sqlite3_file_control()] should +** point to an integer (type int) containing the new chunk-size to use +** for the nominated database. Allocating database file space in large +** chunks (say 1MB at a time), may reduce file-system fragmentation and +** improve performance on some systems. +** +**
    • [[SQLITE_FCNTL_FILE_POINTER]] +** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer +** to the [sqlite3_file] object associated with a particular database +** connection. See also [SQLITE_FCNTL_JOURNAL_POINTER]. +** +**
    • [[SQLITE_FCNTL_JOURNAL_POINTER]] +** The [SQLITE_FCNTL_JOURNAL_POINTER] opcode is used to obtain a pointer +** to the [sqlite3_file] object associated with the journal file (either +** the [rollback journal] or the [write-ahead log]) for a particular database +** connection. See also [SQLITE_FCNTL_FILE_POINTER]. +** +**
    • [[SQLITE_FCNTL_SYNC_OMITTED]] +** No longer in use. +** +**
    • [[SQLITE_FCNTL_SYNC]] +** The [SQLITE_FCNTL_SYNC] opcode is generated internally by SQLite and +** sent to the VFS immediately before the xSync method is invoked on a +** database file descriptor. Or, if the xSync method is not invoked +** because the user has configured SQLite with +** [PRAGMA synchronous | PRAGMA synchronous=OFF] it is invoked in place +** of the xSync method. In most cases, the pointer argument passed with +** this file-control is NULL. However, if the database file is being synced +** as part of a multi-database commit, the argument points to a nul-terminated +** string containing the transactions master-journal file name. VFSes that +** do not need this signal should silently ignore this opcode. Applications +** should not call [sqlite3_file_control()] with this opcode as doing so may +** disrupt the operation of the specialized VFSes that do require it. +** +**
    • [[SQLITE_FCNTL_COMMIT_PHASETWO]] +** The [SQLITE_FCNTL_COMMIT_PHASETWO] opcode is generated internally by SQLite +** and sent to the VFS after a transaction has been committed immediately +** but before the database is unlocked. VFSes that do not need this signal +** should silently ignore this opcode. Applications should not call +** [sqlite3_file_control()] with this opcode as doing so may disrupt the +** operation of the specialized VFSes that do require it. +** +**
    • [[SQLITE_FCNTL_WIN32_AV_RETRY]] +** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic +** retry counts and intervals for certain disk I/O operations for the +** windows [VFS] in order to provide robustness in the presence of +** anti-virus programs. By default, the windows VFS will retry file read, +** file write, and file delete operations up to 10 times, with a delay +** of 25 milliseconds before the first retry and with the delay increasing +** by an additional 25 milliseconds with each subsequent retry. This +** opcode allows these two values (10 retries and 25 milliseconds of delay) +** to be adjusted. The values are changed for all database connections +** within the same process. The argument is a pointer to an array of two +** integers where the first integer i the new retry count and the second +** integer is the delay. If either integer is negative, then the setting +** is not changed but instead the prior value of that setting is written +** into the array entry, allowing the current retry settings to be +** interrogated. The zDbName parameter is ignored. +** +**
    • [[SQLITE_FCNTL_PERSIST_WAL]] +** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the +** persistent [WAL | Write Ahead Log] setting. By default, the auxiliary +** write ahead log and shared memory files used for transaction control +** are automatically deleted when the latest connection to the database +** closes. Setting persistent WAL mode causes those files to persist after +** close. Persisting the files is useful when other processes that do not +** have write permission on the directory containing the database file want +** to read the database file, as the WAL and shared memory files must exist +** in order for the database to be readable. The fourth parameter to +** [sqlite3_file_control()] for this opcode should be a pointer to an integer. +** That integer is 0 to disable persistent WAL mode or 1 to enable persistent +** WAL mode. If the integer is -1, then it is overwritten with the current +** WAL persistence setting. +** +**
    • [[SQLITE_FCNTL_POWERSAFE_OVERWRITE]] +** ^The [SQLITE_FCNTL_POWERSAFE_OVERWRITE] opcode is used to set or query the +** persistent "powersafe-overwrite" or "PSOW" setting. The PSOW setting +** determines the [SQLITE_IOCAP_POWERSAFE_OVERWRITE] bit of the +** xDeviceCharacteristics methods. The fourth parameter to +** [sqlite3_file_control()] for this opcode should be a pointer to an integer. +** That integer is 0 to disable zero-damage mode or 1 to enable zero-damage +** mode. If the integer is -1, then it is overwritten with the current +** zero-damage mode setting. +** +**
    • [[SQLITE_FCNTL_OVERWRITE]] +** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening +** a write transaction to indicate that, unless it is rolled back for some +** reason, the entire database file will be overwritten by the current +** transaction. This is used by VACUUM operations. +** +**
    • [[SQLITE_FCNTL_VFSNAME]] +** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of +** all [VFSes] in the VFS stack. The names are of all VFS shims and the +** final bottom-level VFS are written into memory obtained from +** [sqlite3_malloc()] and the result is stored in the char* variable +** that the fourth parameter of [sqlite3_file_control()] points to. +** The caller is responsible for freeing the memory when done. As with +** all file-control actions, there is no guarantee that this will actually +** do anything. Callers should initialize the char* variable to a NULL +** pointer in case this file-control is not implemented. This file-control +** is intended for diagnostic use only. +** +**
    • [[SQLITE_FCNTL_VFS_POINTER]] +** ^The [SQLITE_FCNTL_VFS_POINTER] opcode finds a pointer to the top-level +** [VFSes] currently in use. ^(The argument X in +** sqlite3_file_control(db,SQLITE_FCNTL_VFS_POINTER,X) must be +** of type "[sqlite3_vfs] **". This opcodes will set *X +** to a pointer to the top-level VFS.)^ +** ^When there are multiple VFS shims in the stack, this opcode finds the +** upper-most shim only. +** +**
    • [[SQLITE_FCNTL_PRAGMA]] +** ^Whenever a [PRAGMA] statement is parsed, an [SQLITE_FCNTL_PRAGMA] +** file control is sent to the open [sqlite3_file] object corresponding +** to the database file to which the pragma statement refers. ^The argument +** to the [SQLITE_FCNTL_PRAGMA] file control is an array of +** pointers to strings (char**) in which the second element of the array +** is the name of the pragma and the third element is the argument to the +** pragma or NULL if the pragma has no argument. ^The handler for an +** [SQLITE_FCNTL_PRAGMA] file control can optionally make the first element +** of the char** argument point to a string obtained from [sqlite3_mprintf()] +** or the equivalent and that string will become the result of the pragma or +** the error message if the pragma fails. ^If the +** [SQLITE_FCNTL_PRAGMA] file control returns [SQLITE_NOTFOUND], then normal +** [PRAGMA] processing continues. ^If the [SQLITE_FCNTL_PRAGMA] +** file control returns [SQLITE_OK], then the parser assumes that the +** VFS has handled the PRAGMA itself and the parser generates a no-op +** prepared statement if result string is NULL, or that returns a copy +** of the result string if the string is non-NULL. +** ^If the [SQLITE_FCNTL_PRAGMA] file control returns +** any result code other than [SQLITE_OK] or [SQLITE_NOTFOUND], that means +** that the VFS encountered an error while handling the [PRAGMA] and the +** compilation of the PRAGMA fails with an error. ^The [SQLITE_FCNTL_PRAGMA] +** file control occurs at the beginning of pragma statement analysis and so +** it is able to override built-in [PRAGMA] statements. +** +**
    • [[SQLITE_FCNTL_BUSYHANDLER]] +** ^The [SQLITE_FCNTL_BUSYHANDLER] +** file-control may be invoked by SQLite on the database file handle +** shortly after it is opened in order to provide a custom VFS with access +** to the connections busy-handler callback. The argument is of type (void **) +** - an array of two (void *) values. The first (void *) actually points +** to a function of type (int (*)(void *)). In order to invoke the connections +** busy-handler, this function should be invoked with the second (void *) in +** the array as the only argument. If it returns non-zero, then the operation +** should be retried. If it returns zero, the custom VFS should abandon the +** current operation. +** +**
    • [[SQLITE_FCNTL_TEMPFILENAME]] +** ^Application can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control +** to have SQLite generate a +** temporary filename using the same algorithm that is followed to generate +** temporary filenames for TEMP tables and other internal uses. The +** argument should be a char** which will be filled with the filename +** written into memory obtained from [sqlite3_malloc()]. The caller should +** invoke [sqlite3_free()] on the result to avoid a memory leak. +** +**
    • [[SQLITE_FCNTL_MMAP_SIZE]] +** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the +** maximum number of bytes that will be used for memory-mapped I/O. +** The argument is a pointer to a value of type sqlite3_int64 that +** is an advisory maximum number of bytes in the file to memory map. The +** pointer is overwritten with the old value. The limit is not changed if +** the value originally pointed to is negative, and so the current limit +** can be queried by passing in a pointer to a negative number. This +** file-control is used internally to implement [PRAGMA mmap_size]. +** +**
    • [[SQLITE_FCNTL_TRACE]] +** The [SQLITE_FCNTL_TRACE] file control provides advisory information +** to the VFS about what the higher layers of the SQLite stack are doing. +** This file control is used by some VFS activity tracing [shims]. +** The argument is a zero-terminated string. Higher layers in the +** SQLite stack may generate instances of this file control if +** the [SQLITE_USE_FCNTL_TRACE] compile-time option is enabled. +** +**
    • [[SQLITE_FCNTL_HAS_MOVED]] +** The [SQLITE_FCNTL_HAS_MOVED] file control interprets its argument as a +** pointer to an integer and it writes a boolean into that integer depending +** on whether or not the file has been renamed, moved, or deleted since it +** was first opened. +** +**
    • [[SQLITE_FCNTL_WIN32_SET_HANDLE]] +** The [SQLITE_FCNTL_WIN32_SET_HANDLE] opcode is used for debugging. This +** opcode causes the xFileControl method to swap the file handle with the one +** pointed to by the pArg argument. This capability is used during testing +** and only needs to be supported when SQLITE_TEST is defined. +** +**
    • [[SQLITE_FCNTL_WAL_BLOCK]] +** The [SQLITE_FCNTL_WAL_BLOCK] is a signal to the VFS layer that it might +** be advantageous to block on the next WAL lock if the lock is not immediately +** available. The WAL subsystem issues this signal during rare +** circumstances in order to fix a problem with priority inversion. +** Applications should not use this file-control. +** +**
    • [[SQLITE_FCNTL_ZIPVFS]] +** The [SQLITE_FCNTL_ZIPVFS] opcode is implemented by zipvfs only. All other +** VFS should return SQLITE_NOTFOUND for this opcode. +** +**
    • [[SQLITE_FCNTL_RBU]] +** The [SQLITE_FCNTL_RBU] opcode is implemented by the special VFS used by +** the RBU extension only. All other VFS should return SQLITE_NOTFOUND for +** this opcode. +**

Additional fields may be appended to this +** object when the iVersion value is increased. Note that the structure +** of the sqlite3_vfs object changes in the transaction between +** SQLite version 3.5.9 and 3.6.0 and yet the iVersion field was not +** modified. +** +** The szOsFile field is the size of the subclassed [sqlite3_file] +** structure used by this VFS. mxPathname is the maximum length of +** a pathname in this VFS. +** +** Registered sqlite3_vfs objects are kept on a linked list formed by +** the pNext pointer.

    • [SQLITE_OPEN_DELETEONCLOSE] +**
    • [SQLITE_OPEN_EXCLUSIVE] +**
    +** +** The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be +** deleted when it is closed. ^The [SQLITE_OPEN_DELETEONCLOSE] +** will be set for TEMP databases and their journals, transient +** databases, and subjournals. +** +** ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction +** with the [SQLITE_OPEN_CREATE] flag, which are both directly +** analogous to the O_EXCL and O_CREAT flags of the POSIX open() +** API. The SQLITE_OPEN_EXCLUSIVE flag, when paired with the +** SQLITE_OPEN_CREATE, is used to indicate that file should always +** be created, and that it is an error if it already exists. +** It is not used to indicate the file should be opened +** for exclusive access. +** +** ^At least szOsFile bytes of memory are allocated by SQLite +** to hold the [sqlite3_file] structure passed as the third +** argument to xOpen.

The return value is +** the actual number of bytes of randomness obtained. +** The xSleep() method causes the calling thread to sleep for at +** least the number of microseconds given. ^The xCurrentTime() +** method returns a Julian Day Number for the current date and time as +** a floating point value. +** ^The xCurrentTimeInt64() method returns, as an integer, the Julian +** Day Number multiplied by 86400000 (the number of milliseconds in +** a 24-hour day). +** ^SQLite will use the xCurrentTimeInt64() method to get the current +** date and time if that method is available (if iVersion is 2 or +** greater and the function pointer is not NULL) and will fall back +** to xCurrentTime() if xCurrentTimeInt64() is unavailable. +** +** ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces +** are not used by the SQLite core.

+**
    +** +** Because the %q format string is used, the '\'' character in zText +** is escaped and the SQL generated is as follows: +** +** 
    +**  INSERT INTO table1 VALUES('It''s a happy day!')
+**
    +** +** This is correct. Had we used %s instead of %q, the generated SQL +** would have looked like this: +** +**

+**
    +** +** This second example is an SQL syntax error. As a general rule you should +** always use %q instead of %s when inserting text into a string literal. +** +** ^(The %Q option works like %q except it also adds single quotes around +** the outside of the total string.

+**  sqlite3_exec(db, zSQL, 0, 0, 0);

      +**
    • vfs: ^The "vfs" parameter may be used to specify the name of +** a VFS object that provides the operating system interface that should +** be used to access the database file on disk. ^If this option is set to +** an empty string the default VFS object is used. ^Specifying an unknown +** VFS is an error. ^If sqlite3_open_v2() is used and the vfs option is +** present, then the VFS specified by the option takes precedence over +** the value passed as the fourth parameter to sqlite3_open_v2(). +** +**

    • cache: ^The cache parameter may be set to either "shared" or +** "private". ^Setting it to "shared" is equivalent to setting the +** SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to +** sqlite3_open_v2(). ^Setting the cache parameter to "private" is +** equivalent to setting the SQLITE_OPEN_PRIVATECACHE bit. +** ^If sqlite3_open_v2() is used and the "cache" parameter is present in +** a URI filename, its value overrides any behavior requested by setting +** SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag. +** +**
    • psow: ^The psow parameter indicates whether or not the +** [powersafe overwrite] property does or does not apply to the +** storage media on which the database file resides. +** +**
    • nolock: ^The nolock parameter is a boolean query parameter +** which if set disables file locking in rollback journal modes. This +** is useful for accessing a database on a filesystem that does not +** support locking. Caution: Database corruption might result if two +** or more processes write to the same database and any one of those +** processes uses nolock=1. +** +**
    • immutable: ^The immutable parameter is a boolean query +** parameter that indicates that the database file is stored on +** read-only media. ^When immutable is set, SQLite assumes that the +** database file cannot be changed, even by a process with higher +** privilege, and so the database is opened read-only and all locking +** and change detection is disabled.

If an application invokes +** any sqlite3_xxx API functions from within an unlock-notify callback, a +** crash or deadlock may be the result. +** +** ^Unless deadlock is detected (see below), sqlite3_unlock_notify() always +** returns SQLITE_OK. +** +** Callback Invocation Details +** +** When an unlock-notify callback is registered, the application provides a +** single void* pointer that is passed to the callback when it is invoked. +** However, the signature of the callback function allows SQLite to pass +** it an array of void* context pointers. The first argument passed to +** an unlock-notify callback is a pointer to an array of void* pointers, +** and the second is the number of entries in the array. +** +** When a blocking connections transaction is concluded, there may be +** more than one blocked connection that has registered for an unlock-notify +** callback. ^If two or more such blocked connections have specified the +** same callback function, then instead of invoking the callback function +** multiple times, it is invoked once with the set of void* context pointers +** specified by the blocked connections bundled together into an array. +** This gives the application an opportunity to prioritize any actions +** related to the set of unblocked database connections. +** +** Deadlock Detection +** +** Assuming that after registering for an unlock-notify callback a +** database waits for the callback to be issued before taking any further +** action (a reasonable assumption), then using this API may cause the +** application to deadlock. For example, if connection X is waiting for +** connection Y's transaction to be concluded, and similarly connection +** Y is waiting on connection X's transaction, then neither connection +** will proceed and the system may remain deadlocked indefinitely. +** +** To avoid this scenario, the sqlite3_unlock_notify() performs deadlock +** detection. ^If a given call to sqlite3_unlock_notify() would put the +** system in a deadlocked state, then SQLITE_LOCKED is returned and no +** unlock-notify callback is registered. The system is said to be in +** a deadlocked state if connection A has registered for an unlock-notify +** callback on the conclusion of connection B's transaction, and connection +** B has itself registered for an unlock-notify callback when connection +** A's transaction is concluded. ^Indirect deadlock is also detected, so +** the system is also considered to be deadlocked if connection B has +** registered for an unlock-notify callback on the conclusion of connection +** C's transaction, where connection C is waiting on connection A. ^Any +** number of levels of indirection are allowed. +** +** The "DROP TABLE" Exception +** +** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost +** always appropriate to call sqlite3_unlock_notify().

When executing a "DROP TABLE" or "DROP INDEX" statement, +** SQLite checks if there are any currently executing SELECT statements +** that belong to the same connection. If there are, SQLITE_LOCKED is +** returned. In this case there is no "blocking connection", so invoking +** sqlite3_unlock_notify() results in the unlock-notify callback being +** invoked immediately. If the application then re-attempts the "DROP TABLE" +** or "DROP INDEX" query, an infinite loop might be the result. +** +** One way around this problem is to check the extended error code returned +** by an sqlite3_step() call. ^(If there is a blocking connection, then the +** extended error code is set to SQLITE_LOCKED_SHAREDCACHE.

A tokenizer +** is registered by providing fts5 with a populated instance of the +** following structure. All structure methods must be defined, setting +** any member of the fts5_tokenizer struct to NULL leads to undefined +** behaviour. The structure methods are expected to function as follows: +** +** xCreate: +** This function is used to allocate and inititalize a tokenizer instance. +** A tokenizer instance is required to actually tokenize text. +** +** The first argument passed to this function is a copy of the (void*) +** pointer provided by the application when the fts5_tokenizer object +** was registered with FTS5 (the third argument to xCreateTokenizer()). +** The second and third arguments are an array of nul-terminated strings +** containing the tokenizer arguments, if any, specified following the +** tokenizer name as part of the CREATE VIRTUAL TABLE statement used +** to create the FTS5 table. +** +** The final argument is an output variable. If successful, (*ppOut) +** should be set to point to the new tokenizer handle and SQLITE_OK +** returned. If an error occurs, some value other than SQLITE_OK should +** be returned. In this case, fts5 assumes that the final value of *ppOut +** is undefined. +** +** xDelete: +** This function is invoked to delete a tokenizer handle previously +** allocated using xCreate(). Fts5 guarantees that this function will +** be invoked exactly once for each successful call to xCreate(). +** +** xTokenize: +** This function is expected to tokenize the nText byte string indicated +** by argument pText. pText may or may not be nul-terminated. The first +** argument passed to this function is a pointer to an Fts5Tokenizer object +** returned by an earlier call to xCreate(). +** +** The second argument indicates the reason that FTS5 is requesting +** tokenization of the supplied text. This is always one of the following +** four values: +** +**
    • FTS5_TOKENIZE_DOCUMENT - A document is being inserted into +** or removed from the FTS table. The tokenizer is being invoked to +** determine the set of tokens to add to (or delete from) the +** FTS index. +** +**
    • FTS5_TOKENIZE_QUERY - A MATCH query is being executed +** against the FTS index. The tokenizer is being called to tokenize +** a bareword or quoted string specified as part of the query. +** +**
    • (FTS5_TOKENIZE_QUERY | FTS5_TOKENIZE_PREFIX) - Same as +** FTS5_TOKENIZE_QUERY, except that the bareword or quoted string is +** followed by a "*" character, indicating that the last token +** returned by the tokenizer will be treated as a token prefix. +** +**
    • FTS5_TOKENIZE_AUX - The tokenizer is being invoked to +** satisfy an fts5_api.xTokenize() request made by an auxiliary +** function. Or an fts5_api.xColumnSize() request made by the same +** on a columnsize=0 database. +**
    +** +** For each token in the input string, the supplied callback xToken() must +** be invoked. The first argument to it should be a copy of the pointer +** passed as the second argument to xTokenize(). The third and fourth +** arguments are a pointer to a buffer containing the token text, and the +** size of the token in bytes. The 4th and 5th arguments are the byte offsets +** of the first byte of and first byte immediately following the text from +** which the token is derived within the input. +** +** The second argument passed to the xToken() callback ("tflags") should +** normally be set to 0. The exception is if the tokenizer supports +** synonyms. In this case see the discussion below for details. +** +** FTS5 assumes the xToken() callback is invoked for each token in the +** order that they occur within the input text. +** +** If an xToken() callback returns any value other than SQLITE_OK, then +** the tokenization should be abandoned and the xTokenize() method should +** immediately return a copy of the xToken() return value. Or, if the +** input buffer is exhausted, xTokenize() should return SQLITE_OK. Finally, +** if an error occurs with the xTokenize() implementation itself, it +** may abandon the tokenization and return any error code other than +** SQLITE_OK or SQLITE_DONE. +** +** SYNONYM SUPPORT +** +** Custom tokenizers may also support synonyms. Consider a case in which a +** user wishes to query for a phrase such as "first place". Using the +** built-in tokenizers, the FTS5 query 'first + place' will match instances +** of "first place" within the document set, but not alternative forms +** such as "1st place". In some applications, it would be better to match +** all instances of "first place" or "1st place" regardless of which form +** the user specified in the MATCH query text. +** +** There are several ways to approach this in FTS5: +** +**
    1. By mapping all synonyms to a single token. In this case, the +** In the above example, this means that the tokenizer returns the +** same token for inputs "first" and "1st". Say that token is in +** fact "first", so that when the user inserts the document "I won +** 1st place" entries are added to the index for tokens "i", "won", +** "first" and "place". If the user then queries for '1st + place', +** the tokenizer substitutes "first" for "1st" and the query works +** as expected. +** +**
    2. By adding multiple synonyms for a single term to the FTS index. +** In this case, when tokenizing query text, the tokenizer may +** provide multiple synonyms for a single term within the document. +** FTS5 then queries the index for each synonym individually. For +** example, faced with the query: +** +** +** ... MATCH 'first place' +** +** the tokenizer offers both "1st" and "first" as synonyms for the +** first token in the MATCH query and FTS5 effectively runs a query +** similar to: +** +** +** ... MATCH '(first OR 1st) place' +** +** except that, for the purposes of auxiliary functions, the query +** still appears to contain just two phrases - "(first OR 1st)" +** being treated as a single phrase. +** +**
    3. By adding multiple synonyms for a single term to the FTS index. +** Using this method, when tokenizing document text, the tokenizer +** provides multiple synonyms for each token. So that when a +** document such as "I won first place" is tokenized, entries are +** added to the FTS index for "i", "won", "first", "1st" and +** "place". +** +** This way, even if the tokenizer does not provide synonyms +** when tokenizing query text (it should not - to do would be +** inefficient), it doesn't matter if the user queries for +** 'first + place' or '1st + place', as there are entires in the +** FTS index corresponding to both forms of the first token. +**
    +** +** Whether it is parsing document or query text, any call to xToken that +** specifies a tflags argument with the FTS5_TOKEN_COLOCATED bit +** is considered to supply a synonym for the previous token. For example, +** when parsing the document "I won first place", a tokenizer that supports +** synonyms would call xToken() 5 times, as follows: +** +** +** xToken(pCtx, 0, "i", 1, 0, 1); +** xToken(pCtx, 0, "won", 3, 2, 5); +** xToken(pCtx, 0, "first", 5, 6, 11); +** xToken(pCtx, FTS5_TOKEN_COLOCATED, "1st", 3, 6, 11); +** xToken(pCtx, 0, "place", 5, 12, 17); +** +** +** It is an error to specify the FTS5_TOKEN_COLOCATED flag the first time +** xToken() is called. Multiple synonyms may be specified for a single token +** by making multiple calls to xToken(FTS5_TOKEN_COLOCATED) in sequence. +** There is no limit to the number of synonyms that may be provided for a +** single token. +** +** In many cases, method (1) above is the best approach. It does not add +** extra data to the FTS index or require FTS5 to query for multiple terms, +** so it is efficient in terms of disk space and query speed. However, it +** does not support prefix queries very well. If, as suggested above, the +** token "first" is subsituted for "1st" by the tokenizer, then the query: +** +** +** ... MATCH '1s*' +** +** will not match documents that contain the token "1st" (as the tokenizer +** will probably not map "1s" to any prefix of "first"). +** +** For full prefix support, method (3) may be preferred. In this case, +** because the index contains entries for both "first" and "1st", prefix +** queries such as 'fi*' or '1s*' will match correctly. However, because +** extra entries are added to the FTS index, this method uses more space +** within the database. +** +** Method (2) offers a midpoint between (1) and (3).

The lock byte is obtained at +** random so two separate readers can probably access the file at the +** same time, unless they are unlucky and choose the same lock byte. +** An EXCLUSIVE_LOCK is obtained by locking all bytes in the range. +** There can only be one writer. A RESERVED_LOCK is obtained by locking +** a single byte of the file that is designated as the reserved lock byte. +** A PENDING_LOCK is obtained by locking a designated byte different from +** the RESERVED_LOCK byte. +** +** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available, +** which means we can use reader/writer locks.

If two adjacent free blocks are the halves of a larger block, +** then the two blocks are coalesced into the single larger block. +** +** 3.

Since both locks came from the same process, the +** second overrides the first, even though they were on different +** file descriptors opened on different file names. +** +** This means that we cannot use POSIX locks to synchronize file access +** among competing threads of the same process. POSIX locks will work fine +** to synchronize access for threads in separate processes, but not +** threads within the same process. +** +** To work around the problem, SQLite has to manage file locks internally +** on its own. Whenever a new database is opened, we have to find the +** specific inode of the database file (the inode is determined by the +** st_dev and st_ino fields of the stat structure that fstat() fills in) +** and check for locks already existing on that inode. When locks are +** created or removed, we have to look at our own internal record of the +** locks to see if another thread has previously set a lock on that same +** inode. +** +** (Aside: The use of inode numbers as unique IDs does not work on VxWorks. +** For VxWorks, we have to use the alternative unique ID system based on +** canonical filename and implemented in the previous division.) +** +** The sqlite3_file structure for POSIX is no longer just an integer file +** descriptor. It is now a structure that holds the integer file +** descriptor and a pointer to a structure that describes the internal +** locks on the corresponding inode. There is one locking structure +** per inode, so if the same inode is opened twice, both unixFile structures +** point to the same locking structure. The locking structure keeps +** a reference count (so we will know when to delete it) and a "cnt" +** field that tells us its internal lock status. cnt==0 means the +** file is unlocked. cnt==-1 means the file has an exclusive lock. +** cnt>0 means there are cnt shared locks on the file. +** +** Any attempt to lock or unlock a file first checks the locking +** structure. The fcntl() system call is only invoked to set a +** POSIX lock if the internal lock structure transitions between +** a locked and an unlocked state. +** +** But wait: there are yet more problems with POSIX advisory locks. +** +** If you close a file descriptor that points to a file that has locks, +** all locks on that file that are owned by the current process are +** released. To work around this problem, each unixInodeInfo object +** maintains a count of the number of pending locks on tha inode. +** When an attempt is made to close an unixFile, if there are +** other unixFile open on the same inode that are holding locks, the call +** to close() the file descriptor is deferred until all of the locks clear. +** The unixInodeInfo structure keeps a list of file descriptors that need to +** be closed and that list is walked (and cleared) when the last lock +** clears. +** +** Yet another problem: LinuxThreads do not play well with posix locks. +** +** Many older versions of linux use the LinuxThreads library which is +** not posix compliant. Under LinuxThreads, a lock created by thread +** A cannot be modified or overridden by a different thread B. +** Only thread A can modify the lock. Locking behavior is correct +** if the appliation uses the newer Native Posix Thread Library (NPTL) +** on linux - with NPTL a lock created by thread A can override locks +** in thread B. But there is no way to know at compile-time which +** threading library is being used. So there is no way to know at +** compile-time whether or not thread A can override locks on thread B. +** One has to do a run-time check to discover the behavior of the +** current process. +** +** SQLite used to support LinuxThreads. But support for LinuxThreads +** was dropped beginning with version 3.7.0. SQLite will still work with +** LinuxThreads provided that (1) there is no more than one connection +** per database file in the same process and (2) database connections +** do not move across threads. +*/ + +/* +** An instance of the following structure serves as the key used +** to locate a particular unixInodeInfo object. +*/ +struct unixFileId { + dev_t dev; /* Device number */ +#if OS_VXWORKS + struct vxworksFileId *pId; /* Unique file ID for vxworks. */ +#else + ino_t ino; /* Inode number */ +#endif +}; + +/* +** An instance of the following structure is allocated for each open +** inode.

The conch file is +** stored in the same directory as the database file and the file name +** is patterned after the database file name as ".-conch". +** If the conch file does not exist, or its contents do not match the +** host ID and/or proxy path, then the lock is escalated to an exclusive +** lock and the conch file contents is updated with the host ID and proxy +** path and the lock is downgraded to a shared lock again. If the conch +** is held by another process (with a shared lock), the exclusive lock +** will fail and SQLITE_BUSY is returned. +** +** The proxy file - a single-byte file used for all advisory file locks +** normally taken on the database file. This allows for safe sharing +** of the database file for multiple readers and writers on the same +** host (the conch ensures that they all use the same local lock file). +** +** Requesting the lock proxy does not immediately take the conch, it is +** only taken when the first request to lock database file is made. +** This matches the semantics of the traditional locking behavior, where +** opening a connection to a database file does not take a lock on it. +** The shared lock and an open file descriptor are maintained until +** the connection to the database is closed. +** +** The proxy file and the lock file are never deleted so they only need +** to be created the first time they are used. +** +** Configuration options +** --------------------- +** +** SQLITE_PREFER_PROXY_LOCKING +** +** Database files accessed on non-local file systems are +** automatically configured for proxy locking, lock files are +** named automatically using the same logic as +** PRAGMA lock_proxy_file=":auto:" +** +** SQLITE_PROXY_DEBUG +** +** Enables the logging of error messages during host id file +** retrieval and creation +** +** LOCKPROXYDIR +** +** Overrides the default directory used for lock proxy files that +** are named automatically via the ":auto:" setting +** +** SQLITE_DEFAULT_PROXYDIR_PERMISSIONS +** +** Permissions to use when creating a directory for storing the +** lock proxy files, only used when LOCKPROXYDIR is not set. +** +** +** As mentioned above, when compiled with SQLITE_PREFER_PROXY_LOCKING, +** setting the environment variable SQLITE_FORCE_PROXY_LOCKING to 1 will +** force proxy locking to be used for every database file opened, and 0 +** will force automatic proxy locking to be disabled for all database +** files (explicitly calling the SQLITE_FCNTL_SET_LOCKPROXYFILE pragma or +** sqlite_file_control API is not affected by SQLITE_FORCE_PROXY_LOCKING). +*/ + +/* +** Proxy locking is only available on MacOSX +*/ +#if defined(__APPLE__) && SQLITE_ENABLE_LOCKING_STYLE + +/* +** The proxyLockingContext has the path and file structures for the remote +** and local proxy files in it +*/ +typedef struct proxyLockingContext proxyLockingContext;

It also contains part of the implementation +** of the SQLITE_CONFIG_PAGECACHE and sqlite3_release_memory() features. +** If the default page cache implementation is overridden, then neither of +** these two features are available. +** +** A Page cache line looks like this: +** +** ------------------------------------------------------------- +** | database page content | PgHdr1 | MemPage | PgHdr | +** ------------------------------------------------------------- +** +** The database page content is up front (so that buffer overreads tend to +** flow harmlessly into the PgHdr1, MemPage, and PgHdr extensions). MemPage +** is the extension added by the btree.c module containing information such +** as the database page number and how that database page is used. PgHdr +** is added by the pcache.c layer and contains information used to keep track +** of which pages are "dirty". PgHdr1 is an extension added by this +** module (pcache1.c). The PgHdr1 header is a subclass of sqlite3_pcache_page. +** PgHdr1 contains information needed to look up a page by its page number. +** The superclass sqlite3_pcache_page.pBuf points to the start of the +** database page content and sqlite3_pcache_page.pExtra points to PgHdr. +** +** The size of the extension (MemPage+PgHdr+PgHdr1) can be determined at +** runtime using sqlite3_config(SQLITE_CONFIG_PCACHE_HDRSZ, &size). The +** sizes of the extensions sum to 272 bytes on x64 for 3.8.10, but this +** size can vary according to architecture, compile-time options, and +** SQLite library version number. +** +** If SQLITE_PCACHE_SEPARATE_HEADER is defined, then the extension is obtained +** using a separate memory allocation from the database page content. This +** seeks to overcome the "clownshoe" problem (also called "internal +** fragmentation" in academic literature) of allocating a few bytes more +** than a power of two with the memory allocator rounding up to the next +** power of two, and leaving the rounded-up space unused. +** +** This module tracks pointers to PgHdr1 objects. Only pcache.c communicates +** with this module. Information is passed back and forth as PgHdr1 pointers. +** +** The pcache.c and pager.c modules deal pointers to PgHdr objects. +** The btree.c module deals with pointers to MemPage objects. +** +** SOURCE OF PAGE CACHE MEMORY: +** +** Memory for a page might come from any of three sources: +** +** (1) The general-purpose memory allocator - sqlite3Malloc() +** (2) Global page-cache memory provided using sqlite3_config() with +** SQLITE_CONFIG_PAGECACHE. +** (3) PCache-local bulk allocation. +** +** The third case is a chunk of heap memory (defaulting to 100 pages worth) +** that is allocated when the page cache is created. The size of the local +** bulk allocation can be adjusted using +** +** sqlite3_config(SQLITE_CONFIG_PAGECACHE, (void*)0, 0, N). +** +** If N is positive, then N pages worth of memory are allocated using a single +** sqlite3Malloc() call and that memory is used for the first N pages allocated. +** Or if N is negative, then -1024*N bytes of memory are allocated and used +** for as many pages as can be accomodated. +** +** Only one of (2) or (3) can be used. Once the memory available to (2) or +** (3) is exhausted, subsequent allocations fail over to the general-purpose +** memory allocator (1). +** +** Earlier versions of SQLite used only methods (1) and (2). But experiments +** show that method (3) with N==100 provides about a 5% performance boost for +** common workloads. +*/ +/* #include "sqliteInt.h" */ + +typedef struct PCache1 PCache1; +typedef struct PgHdr1 PgHdr1; +typedef struct PgFreeslot PgFreeslot; +typedef struct PGroup PGroup; + +/* +** Each cache entry is represented by an instance of the following +** structure.

Rowids +** are inserted into the RowSet in an arbitrary order. Inserts +** can be intermixed with tests to see if a given rowid has been +** previously inserted into the RowSet. +** +** After all inserts are finished, it is possible to extract the +** elements of the RowSet in sorted order. Once this extraction +** process has started, no new elements may be inserted. +** +** Hence, the primitive operations for a RowSet are: +** +** CREATE +** INSERT +** TEST +** SMALLEST +** DESTROY +** +** The CREATE and DESTROY primitives are the constructor and destructor, +** obviously. The INSERT primitive adds a new element to the RowSet. +** TEST checks to see if an element is already in the RowSet. SMALLEST +** extracts the least value from the RowSet. +** +** The INSERT primitive might allocate additional memory. Memory is +** allocated in chunks so most INSERTs do no allocation. There is an +** upper bound on the size of allocated memory. No memory is freed +** until DESTROY. +** +** The TEST primitive includes a "batch" number. The TEST primitive +** will only see elements that were inserted before the last change +** in the batch number. In other words, if an INSERT occurs between +** two TESTs where the TESTs have the same batch nubmer, then the +** value added by the INSERT will not be visible to the second TEST. +** The initial batch number is zero, so if the very first TEST contains +** a non-zero batch number, it will see all prior INSERTs. +** +** No INSERTs may occurs after a SMALLEST. An assertion will fail if +** that is attempted. +** +** The cost of an INSERT is roughly constant. (Sometimes new memory +** has to be allocated on an INSERT.) The cost of a TEST with a new +** batch number is O(NlogN) where N is the number of elements in the RowSet. +** The cost of a TEST using the same batch number is O(logN). The cost +** of the first SMALLEST is O(NlogN). Second and subsequent SMALLEST +** primitives are constant time. The cost of DESTROY is O(N). +** +** There is an added cost of O(N) when switching between TEST and +** SMALLEST primitives. +*/ +/* #include "sqliteInt.h" */ + + +/* +** Target size for allocation chunks. +*/ +#define ROWSET_ALLOCATION_SIZE 1024 + +/* +** The number of rowset entries per allocation chunk. +*/ +#define ROWSET_ENTRY_PER_CHUNK \ + ((ROWSET_ALLOCATION_SIZE-8)/sizeof(struct RowSetEntry)) + +/* +** Each entry in a RowSet is an instance of the following object. +** +** This same object is reused to store a linked list of trees of RowSetEntry +** objects.

The database file on disk has not been modified. +** +** * A write transaction is active. +** * A RESERVED or greater lock is held on the database file. +** * The journal file is open and the first header has been written +** to it, but the header has not been synced to disk. +** * The contents of the page cache have been modified. +** +** WRITER_DBMOD: +** +** The pager transitions from WRITER_CACHEMOD into WRITER_DBMOD state +** when it modifies the contents of the database file. WAL connections +** never enter this state (since they do not modify the database file, +** just the log file). +** +** * A write transaction is active. +** * An EXCLUSIVE or greater lock is held on the database file. +** * The journal file is open and the first header has been written +** and synced to disk. +** * The contents of the page cache have been modified (and possibly +** written to disk). +** +** WRITER_FINISHED: +** +** It is not possible for a WAL connection to enter this state. +** +** A rollback-mode pager changes to WRITER_FINISHED state from WRITER_DBMOD +** state after the entire transaction has been successfully written into the +** database file. In this state the transaction may be committed simply +** by finalizing the journal file. Once in WRITER_FINISHED state, it is +** not possible to modify the database further. At this point, the upper +** layer must either commit or rollback the transaction. +** +** * A write transaction is active. +** * An EXCLUSIVE or greater lock is held on the database file. +** * All writing and syncing of journal and database data has finished. +** If no error occurred, all that remains is to finalize the journal to +** commit the transaction. If an error did occur, the caller will need +** to rollback the transaction. +** +** ERROR: +** +** The ERROR state is entered when an IO or disk-full error (including +** SQLITE_IOERR_NOMEM) occurs at a point in the code that makes it +** difficult to be sure that the in-memory pager state (cache contents, +** db size etc.) are consistent with the contents of the file-system. +** +** Temporary pager files may enter the ERROR state, but in-memory pagers +** cannot. +** +** For example, if an IO error occurs while performing a rollback, +** the contents of the page-cache may be left in an inconsistent state. +** At this point it would be dangerous to change back to READER state +** (as usually happens after a rollback). Any subsequent readers might +** report database corruption (due to the inconsistent cache), and if +** they upgrade to writers, they may inadvertently corrupt the database +** file. To avoid this hazard, the pager switches into the ERROR state +** instead of READER following such an error. +** +** Once it has entered the ERROR state, any attempt to use the pager +** to read or write data returns an error. Eventually, once all +** outstanding transactions have been abandoned, the pager is able to +** transition back to OPEN state, discarding the contents of the +** page-cache and any other in-memory state at the same time. Everything +** is reloaded from disk (and, if necessary, hot-journal rollback peformed) +** when a read-transaction is next opened on the pager (transitioning +** the pager into READER state). At that point the system has recovered +** from the error. +** +** Specifically, the pager jumps into the ERROR state if: +** +** 1. An error occurs while attempting a rollback. This happens in +** function sqlite3PagerRollback(). +** +** 2. An error occurs while attempting to finalize a journal file +** following a commit in function sqlite3PagerCommitPhaseTwo(). +** +** 3. An error occurs while attempting to write to the journal or +** database file in function pagerStress() in order to free up +** memory. +** +** In other cases, the error is returned to the b-tree layer. The b-tree +** layer then attempts a rollback operation. If the error condition +** persists, the pager enters the ERROR state via condition (1) above. +** +** Condition (3) is necessary because it can be triggered by a read-only +** statement executed within a transaction. In this case, if the error +** code were simply returned to the user, the b-tree layer would not +** automatically attempt a rollback, as it assumes that an error in a +** read-only statement cannot leave the pager in an internally inconsistent +** state. +** +** * The Pager.errCode variable is set to something other than SQLITE_OK. +** * There are one or more outstanding references to pages (after the +** last reference is dropped the pager should move back to OPEN state). +** * The pager is not an in-memory pager. +** +** +** Notes: +** +** * A pager is never in WRITER_DBMOD or WRITER_FINISHED state if the +** connection is open in WAL mode. A WAL connection is always in one +** of the first four states. +** +** * Normally, a connection open in exclusive mode is never in PAGER_OPEN +** state.

In these circumstances pagerLockDb() and +** pagerUnlockDb() take a conservative approach - eLock is always updated +** when unlocking the file, and only updated when locking the file if the +** VFS call is successful. This way, the Pager.eLock variable may be set +** to a less exclusive (lower) value than the lock that is actually held +** at the system level, but it is never set to a more exclusive value. +** +** This is usually safe.

If it is true, the work of +** updating the change-counter is omitted for the current transaction. +** +** This mechanism means that when running in exclusive mode, a connection +** need only update the change-counter once, for the first transaction +** committed. +** +** setMaster +** +** When PagerCommitPhaseOne() is called to commit a transaction, it may +** (or may not) specify a master-journal name to be written into the +** journal file before it is synced to disk. +** +** Whether or not a journal file contains a master-journal pointer affects +** the way in which the journal file is finalized after the transaction is +** committed or rolled back when running in "journal_mode=PERSIST" mode. +** If a journal file does not contain a master-journal pointer, it is +** finalized by overwriting the first journal header with zeroes. If +** it does contain a master-journal pointer the journal file is finalized +** by truncating it to zero bytes, just as if the connection were +** running in "journal_mode=truncate" mode. +** +** Journal files that contain master journal pointers cannot be finalized +** simply by overwriting the first journal-header with zeroes, as the +** master journal pointer could interfere with hot-journal rollback of any +** subsequently interrupted transaction that reuses the journal file. +** +** The flag is cleared as soon as the journal file is finalized (either +** by PagerCommitPhaseTwo or PagerRollback). If an IO error prevents the +** journal file from being successfully finalized, the setMaster flag +** is cleared anyway (and the pager will move to ERROR state). +** +** doNotSpill +** +** This variables control the behavior of cache-spills (calls made by +** the pcache module to the pagerStress() routine to write cached data +** to the file-system in order to free up memory). +** +** When bits SPILLFLAG_OFF or SPILLFLAG_ROLLBACK of doNotSpill are set, +** writing to the database from pagerStress() is disabled altogether. +** The SPILLFLAG_ROLLBACK case is done in a very obscure case that +** comes up during savepoint rollback that requires the pcache module +** to allocate a new page to prevent the journal file from being written +** while it is being traversed by code in pager_playback(). The SPILLFLAG_OFF +** case is a user preference. +** +** If the SPILLFLAG_NOSYNC bit is set, writing to the database from +** pagerStress() is permitted, but syncing the journal file is not. +** This flag is set by sqlite3PagerWrite() when the file-system sector-size +** is larger than the database page-size in order to prevent a journal sync +** from happening in between the journalling of two pages on the same sector. +** +** subjInMemory +** +** This is a boolean variable. If true, then any required sub-journal +** is opened as an in-memory journal file. If false, then in-memory +** sub-journals are only used for in-memory pager files. +** +** This variable is updated by the upper layer each time a new +** write-transaction is opened. +** +** dbSize, dbOrigSize, dbFileSize +** +** Variable dbSize is set to the number of pages in the database file. +** It is valid in PAGER_READER and higher states (all states except for +** OPEN and ERROR). +** +** dbSize is set based on the size of the database file, which may be +** larger than the size of the database (the value stored at offset +** 28 of the database header by the btree). If the size of the file +** is not an integer multiple of the page-size, the value stored in +** dbSize is rounded down (i.e. a 5KB file with 2K page-size has dbSize==2). +** Except, any file that is greater than 0 bytes in size is considered +** to have at least one page. (i.e. a 1KB file with 2K page-size leads +** to dbSize==1). +** +** During a write-transaction, if pages with page-numbers greater than +** dbSize are modified in the cache, dbSize is updated accordingly. +** Similarly, if the database is truncated using PagerTruncateImage(), +** dbSize is updated. +** +** Variables dbOrigSize and dbFileSize are valid in states +** PAGER_WRITER_LOCKED and higher. dbOrigSize is a copy of the dbSize +** variable at the start of the transaction. It is used during rollback, +** and to determine whether or not pages need to be journalled before +** being modified. +** +** Throughout a write-transaction, dbFileSize contains the size of +** the file on disk in pages. It is set to a copy of dbSize when the +** write-transaction is first opened, and updated when VFS calls are made +** to write or truncate the database file on disk. +** +** The only reason the dbFileSize variable is required is to suppress +** unnecessary calls to xTruncate() after committing a transaction. If, +** when a transaction is committed, the dbFileSize variable indicates +** that the database file is larger than the database image (Pager.dbSize), +** pager_truncate() is called. The pager_truncate() call uses xFilesize() +** to measure the database file on disk, and then truncates it if required. +** dbFileSize is not used when rolling back a transaction. In this case +** pager_truncate() is called unconditionally (which means there may be +** a call to xFilesize() that is not strictly required).

All changes to the database are recorded by writing +** frames into the WAL. Transactions commit when a frame is written that +** contains a commit marker. A single WAL can and usually does record +** multiple transactions. Periodically, the content of the WAL is +** transferred back into the database file in an operation called a +** "checkpoint". +** +** A single WAL file can be used multiple times. In other words, the +** WAL can fill up with frames and then be checkpointed and then new +** frames can overwrite the old ones. A WAL always grows from beginning +** toward the end. Checksums and counters attached to each frame are +** used to determine which frames within the WAL are valid and which +** are leftovers from prior checkpoints. +** +** The WAL header is 32 bytes in size and consists of the following eight +** big-endian 32-bit unsigned integer values: +** +** 0: Magic number. 0x377f0682 or 0x377f0683 +** 4: File format version. Currently 3007000 +** 8: Database page size. Example: 1024 +** 12: Checkpoint sequence number +** 16: Salt-1, random integer incremented with each checkpoint +** 20: Salt-2, a different random integer changing with each ckpt +** 24: Checksum-1 (first part of checksum for first 24 bytes of header). +** 28: Checksum-2 (second part of checksum for first 24 bytes of header). +** +** Immediately following the wal-header are zero or more frames. Each +** frame consists of a 24-byte frame-header followed by a bytes +** of page data. The frame-header is six big-endian 32-bit unsigned +** integer values, as follows: +** +** 0: Page number. +** 4: For commit records, the size of the database image in pages +** after the commit. For all other records, zero. +** 8: Salt-1 (copied from the header) +** 12: Salt-2 (copied from the header) +** 16: Checksum-1. +** 20: Checksum-2. +** +** A frame is considered valid if and only if the following conditions are +** true: +** +** (1) The salt-1 and salt-2 values in the frame-header match +** salt values in the wal-header +** +** (2) The checksum values in the final 8 bytes of the frame-header +** exactly match the checksum computed consecutively on the +** WAL header and the first 8 bytes and the content of all frames +** up to and including the current frame. +** +** The checksum is computed using 32-bit big-endian integers if the +** magic number in the first 4 bytes of the WAL is 0x377f0683 and it +** is computed using little-endian if the magic number is 0x377f0682. +** The checksum values are always stored in the frame header in a +** big-endian format regardless of which byte order is used to compute +** the checksum. The checksum is computed by interpreting the input as +** an even number of unsigned 32-bit integers: x[0] through x[N]. The +** algorithm used for the checksum is as follows: +** +** for i from 0 to n-1 step 2: +** s0 += x[i] + s1; +** s1 += x[i+1] + s0; +** endfor +** +** Note that s0 and s1 are both weighted checksums using fibonacci weights +** in reverse order (the largest fibonacci weight occurs on the first element +** of the sequence being summed.) The s1 value spans all 32-bit +** terms of the sequence whereas s0 omits the final term. +** +** On a checkpoint, the WAL is first VFS.xSync-ed, then valid content of the +** WAL is transferred into the database, then the database is VFS.xSync-ed. +** The VFS.xSync operations serve as write barriers - all writes launched +** before the xSync must complete before any write that launches after the +** xSync begins. +** +** After each checkpoint, the salt-1 value is incremented and the salt-2 +** value is randomized. This prevents old and new frames in the WAL from +** being considered valid at the same time and being checkpointing together +** following a crash. +** +** READER ALGORITHM +** +** To read a page from the database (call it page number P), a reader +** first checks the WAL to see if it contains page P. If so, then the +** last valid instance of page P that is a followed by a commit frame +** or is a commit frame itself becomes the value read. If the WAL +** contains no copies of page P that are valid and which are a commit +** frame or are followed by a commit frame, then page P is read from +** the database file. +** +** To start a read transaction, the reader records the index of the last +** valid frame in the WAL. The reader uses this recorded "mxFrame" value +** for all subsequent read operations. New transactions can be appended +** to the WAL, but as long as the reader uses its original mxFrame value +** and ignores the newly appended content, it will see a consistent snapshot +** of the database from a single point in time. This technique allows +** multiple concurrent readers to view different versions of the database +** content simultaneously. +** +** The reader algorithm in the previous paragraphs works correctly, but +** because frames for page P can appear anywhere within the WAL, the +** reader has to scan the entire WAL looking for page P frames. If the +** WAL is large (multiple megabytes is typical) that scan can be slow, +** and read performance suffers. To overcome this problem, a separate +** data structure called the wal-index is maintained to expedite the +** search for frames of a particular page. +** +** WAL-INDEX FORMAT +** +** Conceptually, the wal-index is shared memory, though VFS implementations +** might choose to implement the wal-index using a mmapped file. Because +** the wal-index is shared memory, SQLite does not support journal_mode=WAL +** on a network filesystem. All users of the database must be able to +** share memory. +** +** The wal-index is transient. After a crash, the wal-index can (and should +** be) reconstructed from the original WAL file. In fact, the VFS is required +** to either truncate or zero the header of the wal-index when the last +** connection to it closes. Because the wal-index is transient, it can +** use an architecture-specific format; it does not have to be cross-platform. +** Hence, unlike the database and WAL file formats which store all values +** as big endian, the wal-index can store multi-byte values in the native +** byte order of the host computer. +** +** The purpose of the wal-index is to answer this question quickly: Given +** a page number P and a maximum frame index M, return the index of the +** last frame in the wal before frame M for page P in the WAL, or return +** NULL if there are no frames for page P in the WAL prior to M. +** +** The wal-index consists of a header region, followed by an one or +** more index blocks. +** +** The wal-index header contains the total number of frames within the WAL +** in the mxFrame field. +** +** Each index block except for the first contains information on +** HASHTABLE_NPAGE frames. The first index block contains information on +** HASHTABLE_NPAGE_ONE frames. The values of HASHTABLE_NPAGE_ONE and +** HASHTABLE_NPAGE are selected so that together the wal-index header and +** first index block are the same size as all other index blocks in the +** wal-index. +** +** Each index block contains two sections, a page-mapping that contains the +** database page number associated with each wal frame, and a hash-table +** that allows readers to query an index block for a specific page number. +** The page-mapping is an array of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE +** for the first index block) 32-bit page numbers. The first entry in the +** first index-block contains the database page number corresponding to the +** first frame in the WAL file. The first entry in the second index block +** in the WAL file corresponds to the (HASHTABLE_NPAGE_ONE+1)th frame in +** the log, and so on. +** +** The last index block in a wal-index usually contains less than the full +** complement of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE) page-numbers, +** depending on the contents of the WAL file. This does not change the +** allocated size of the page-mapping array - the page-mapping array merely +** contains unused entries. +** +** Even without using the hash table, the last frame for page P +** can be found by scanning the page-mapping sections of each index block +** starting with the last index block and moving toward the first, and +** within each index block, starting at the end and moving toward the +** beginning. The first entry that equals P corresponds to the frame +** holding the content for that page. +** +** The hash table consists of HASHTABLE_NSLOT 16-bit unsigned integers. +** HASHTABLE_NSLOT = 2*HASHTABLE_NPAGE, and there is one entry in the +** hash table for each page number in the mapping section, so the hash +** table is never more than half full. The expected number of collisions +** prior to finding a match is 1. Each entry of the hash table is an +** 1-based index of an entry in the mapping section of the same +** index block. Let K be the 1-based index of the largest entry in +** the mapping section. (For index blocks other than the last, K will +** always be exactly HASHTABLE_NPAGE (4096) and for the last index block +** K will be (mxFrame%HASHTABLE_NPAGE).) Unused slots of the hash table +** contain a value of 0. +** +** To look for page P in the hash table, first compute a hash iKey on +** P as follows: +** +** iKey = (P * 383) % HASHTABLE_NSLOT +** +** Then start scanning entries of the hash table, starting with iKey +** (wrapping around to the beginning when the end of the hash table is +** reached) until an unused hash slot is found. Let the first unused slot +** be at index iUnused. (iUnused might be less than iKey if there was +** wrap-around.) Because the hash table is never more than half full, +** the search is guaranteed to eventually hit an unused entry. Let +** iMax be the value between iKey and iUnused, closest to iUnused, +** where aHash[iMax]==P. If there is no iMax entry (if there exists +** no hash slot such that aHash[i]==p) then page P is not in the +** current index block. Otherwise the iMax-th mapping entry of the +** current index block corresponds to the last entry that references +** page P. +** +** A hash search begins with the last index block and moves toward the +** first index block, looking for entries corresponding to page P. On +** average, only two or three slots in each index block need to be +** examined in order to either find the last entry for page P, or to +** establish that no such entry exists in the block. Each index block +** holds over 4000 entries. So two or three index blocks are sufficient +** to cover a typical 10 megabyte WAL file, assuming 1K pages. 8 or 10 +** comparisons (on average) suffice to either locate a frame in the +** WAL or to establish that the frame does not exist in the WAL. This +** is much faster than scanning the entire 10MB WAL. +** +** Note that entries are added in order of increasing K. Hence, one +** reader might be using some value K0 and a second reader that started +** at a later time (after additional transactions were added to the WAL +** and to the wal-index) might be using a different value K1, where K1>K0. +** Both readers can use the same hash table and mapping section to get +** the correct result. There may be entries in the hash table with +** K>K0 but to the first reader, those entries will appear to be unused +** slots in the hash table and so the first reader will get an answer as +** if no values greater than K0 had ever been inserted into the hash table +** in the first place - which is what reader one wants. Meanwhile, the +** second reader using K1 will see additional values that were inserted +** later, which is exactly what reader two wants. +** +** When a rollback occurs, the value of K is decreased. Hash table entries +** that correspond to frames greater than the new K value are removed +** from the hash table at this point. +*/ +#ifndef SQLITE_OMIT_WAL + +/* #include "wal.h" */ + +/* +** Trace output macros +*/ +#if defined(SQLITE_TEST) && defined(SQLITE_DEBUG) +SQLITE_PRIVATE int sqlite3WalTrace = 0; +# define WALTRACE(X) if(sqlite3WalTrace) sqlite3DebugPrintf X +#else +# define WALTRACE(X) +#endif + +/* +** The maximum (and only) versions of the wal and wal-index formats +** that may be interpreted by this version of SQLite. +** +** If a client begins recovering a WAL file and finds that (a) the checksum +** values in the wal-header are correct and (b) the version field is not +** WAL_MAX_VERSION, recovery fails and SQLite returns SQLITE_CANTOPEN. +** +** Similarly, if a client successfully reads a wal-index header (i.e. the +** checksum test is successful) and finds that the version field is not +** WALINDEX_MAX_VERSION, then no read-transaction is opened and SQLite +** returns SQLITE_CANTOPEN. +*/ +#define WAL_MAX_VERSION 3007000 +#define WALINDEX_MAX_VERSION 3007000 + +/* +** Indices of various locking bytes.

Knuth, THE ART OF COMPUTER PROGRAMMING, Volume 3: +** "Sorting And Searching", pages 473-480. Addison-Wesley +** Publishing Company, Reading, Massachusetts. +** +** The basic idea is that each page of the file contains N database +** entries and N+1 pointers to subpages. +** +** ---------------------------------------------------------------- +** | Ptr(0) | Key(0) | Ptr(1) | Key(1) | ... | Key(N-1) | Ptr(N) | +** ---------------------------------------------------------------- +** +** All of the keys on the page that Ptr(0) points to have values less +** than Key(0). All of the keys on page Ptr(1) and its subpages have +** values greater than Key(0) and less than Key(1). All of the keys +** on Ptr(N) and its subpages have values greater than Key(N-1). And +** so forth. +** +** Finding a particular key requires reading O(log(M)) pages from the +** disk where M is the number of entries in the tree. +** +** In this implementation, a single file can hold one or more separate +** BTrees. Each BTree is identified by the index of its root page. The +** key and data for any entry are combined to form the "payload". A +** fixed amount of payload can be carried directly on the database +** page. If the payload is larger than the preset amount then surplus +** bytes are stored on overflow pages. The payload for an entry +** and the preceding pointer are combined to form a "Cell". Each +** page has a small header which contains the Ptr(N) pointer and other +** information such as the size of key and data. +** +** FORMAT DETAILS +** +** The file is divided into pages. The first page is called page 1, +** the second is page 2, and so forth. A page number of zero indicates +** "no such page". The page size can be any power of 2 between 512 and 65536. +** Each page can be either a btree page, a freelist page, an overflow +** page, or a pointer-map page. +** +** The first page is always a btree page. The first 100 bytes of the first +** page contain a special header (the "file header") that describes the file. +** The format of the file header is as follows: +** +** OFFSET SIZE DESCRIPTION +** 0 16 Header string: "SQLite format 3\000" +** 16 2 Page size in bytes. (1 means 65536) +** 18 1 File format write version +** 19 1 File format read version +** 20 1 Bytes of unused space at the end of each page +** 21 1 Max embedded payload fraction (must be 64) +** 22 1 Min embedded payload fraction (must be 32) +** 23 1 Min leaf payload fraction (must be 32) +** 24 4 File change counter +** 28 4 Reserved for future use +** 32 4 First freelist page +** 36 4 Number of freelist pages in the file +** 40 60 15 4-byte meta values passed to higher layers +** +** 40 4 Schema cookie +** 44 4 File format of schema layer +** 48 4 Size of page cache +** 52 4 Largest root-page (auto/incr_vacuum) +** 56 4 1=UTF-8 2=UTF16le 3=UTF16be +** 60 4 User version +** 64 4 Incremental vacuum mode +** 68 4 Application-ID +** 72 20 unused +** 92 4 The version-valid-for number +** 96 4 SQLITE_VERSION_NUMBER +** +** All of the integer values are big-endian (most significant byte first). +** +** The file change counter is incremented when the database is changed +** This counter allows other processes to know when the file has changed +** and thus when they need to flush their cache. +** +** The max embedded payload fraction is the amount of the total usable +** space in a page that can be consumed by a single cell for standard +** B-tree (non-LEAFDATA) tables. A value of 255 means 100%. The default +** is to limit the maximum cell size so that at least 4 cells will fit +** on one page. Thus the default max embedded payload fraction is 64. +** +** If the payload for a cell is larger than the max payload, then extra +** payload is spilled to overflow pages. Once an overflow page is allocated, +** as many bytes as possible are moved into the overflow pages without letting +** the cell size drop below the min embedded payload fraction. +** +** The min leaf payload fraction is like the min embedded payload fraction +** except that it applies to leaf nodes in a LEAFDATA tree. The maximum +** payload fraction for a LEAFDATA tree is always 100% (or 255) and it +** not specified in the header. +** +** Each btree pages is divided into three sections: The header, the +** cell pointer array, and the cell content area. Page 1 also has a 100-byte +** file header that occurs before the page header. +** +** |----------------| +** | file header | 100 bytes. Page 1 only. +** |----------------| +** | page header | 8 bytes for leaves. 12 bytes for interior nodes +** |----------------| +** | cell pointer | | 2 bytes per cell. Sorted order. +** | array | | Grows downward +** | | v +** |----------------| +** | unallocated | +** | space | +** |----------------| ^ Grows upwards +** | cell content | | Arbitrary order interspersed with freeblocks. +** | area | | and free space fragments. +** |----------------| +** +** The page headers looks like this: +** +** OFFSET SIZE DESCRIPTION +** 0 1 Flags. 1: intkey, 2: zerodata, 4: leafdata, 8: leaf +** 1 2 byte offset to the first freeblock +** 3 2 number of cells on this page +** 5 2 first byte of the cell content area +** 7 1 number of fragmented free bytes +** 8 4 Right child (the Ptr(N) value). Omitted on leaves. +** +** The flags define the format of this btree page. The leaf flag means that +** this page has no children. The zerodata flag means that this page carries +** only keys and no data. The intkey flag means that the key is an integer +** which is stored in the key size entry of the cell header rather than in +** the payload area. +** +** The cell pointer array begins on the first byte after the page header. +** The cell pointer array contains zero or more 2-byte numbers which are +** offsets from the beginning of the page to the cell content in the cell +** content area. The cell pointers occur in sorted order. The system strives +** to keep free space after the last cell pointer so that new cells can +** be easily added without having to defragment the page. +** +** Cell content is stored at the very end of the page and grows toward the +** beginning of the page. +** +** Unused space within the cell content area is collected into a linked list of +** freeblocks. Each freeblock is at least 4 bytes in size. The byte offset +** to the first freeblock is given in the header. Freeblocks occur in +** increasing order. Because a freeblock must be at least 4 bytes in size, +** any group of 3 or fewer unused bytes in the cell content area cannot +** exist on the freeblock chain. A group of 3 or fewer free bytes is called +** a fragment. The total number of bytes in all fragments is recorded. +** in the page header at offset 7. +** +** SIZE DESCRIPTION +** 2 Byte offset of the next freeblock +** 2 Bytes in this freeblock +** +** Cells are of variable length. Cells are stored in the cell content area at +** the end of the page. Pointers to the cells are in the cell pointer array +** that immediately follows the page header. Cells is not necessarily +** contiguous or in order, but cell pointers are contiguous and in order. +** +** Cell content makes use of variable length integers. A variable +** length integer is 1 to 9 bytes where the lower 7 bits of each +** byte are used. The integer consists of all bytes that have bit 8 set and +** the first byte with bit 8 clear. The most significant byte of the integer +** appears first. A variable-length integer may not be more than 9 bytes long. +** As a special case, all 8 bytes of the 9th byte are used as data. This +** allows a 64-bit integer to be encoded in 9 bytes. +** +** 0x00 becomes 0x00000000 +** 0x7f becomes 0x0000007f +** 0x81 0x00 becomes 0x00000080 +** 0x82 0x00 becomes 0x00000100 +** 0x80 0x7f becomes 0x0000007f +** 0x8a 0x91 0xd1 0xac 0x78 becomes 0x12345678 +** 0x81 0x81 0x81 0x81 0x01 becomes 0x10204081 +** +** Variable length integers are used for rowids and to hold the number of +** bytes of key and data in a btree cell. +** +** The content of a cell looks like this: +** +** SIZE DESCRIPTION +** 4 Page number of the left child.

The row is a binary blob in the +** OP_MakeRecord format that contains both +** the ORDER BY key columns and result columns +** in the case of a SELECT w/ ORDER BY, or +** the complete record for an index entry +** in the case of a CREATE INDEX. +** +** sqlite3VdbeSorterRewind() Sort all content previously added. +** Position the read cursor on the +** first sorted element. +** +** sqlite3VdbeSorterNext() Advance the read cursor to the next sorted +** element. +** +** sqlite3VdbeSorterRowkey() Return the complete binary blob for the +** row currently under the read cursor. +** +** sqlite3VdbeSorterCompare() Compare the binary blob for the row +** currently under the read cursor against +** another binary blob X and report if +** X is strictly less than the read cursor. +** Used to enforce uniqueness in a +** CREATE UNIQUE INDEX statement. +** +** sqlite3VdbeSorterClose() Close the VdbeSorter object and reclaim +** all resources. +** +** sqlite3VdbeSorterReset() Refurbish the VdbeSorter for reuse. This +** is like Close() followed by Init() only +** much faster. +** +** The interfaces above must be called in a particular order. Write() can +** only occur in between Init()/Reset() and Rewind(). Next(), Rowkey(), and +** Compare() can only occur in between Rewind() and Close()/Reset(). i.e. +** +** Init() +** for each record: Write() +** Rewind() +** Rowkey()/Compare() +** Next() +** Close() +** +** Algorithm: +** +** Records passed to the sorter via calls to Write() are initially held +** unsorted in main memory. Assuming the amount of memory used never exceeds +** a threshold, when Rewind() is called the set of records is sorted using +** an in-memory merge sort. In this case, no temporary files are required +** and subsequent calls to Rowkey(), Next() and Compare() read records +** directly from main memory. +** +** If the amount of space used to store records in main memory exceeds the +** threshold, then the set of records currently in memory are sorted and +** written to a temporary file in "Packed Memory Array" (PMA) format. +** A PMA created at this point is known as a "level-0 PMA". Higher levels +** of PMAs may be created by merging existing PMAs together - for example +** merging two or more level-0 PMAs together creates a level-1 PMA. +** +** The threshold for the amount of main memory to use before flushing +** records to a PMA is roughly the same as the limit configured for the +** page-cache of the main database. Specifically, the threshold is set to +** the value returned by "PRAGMA main.page_size" multipled by +** that returned by "PRAGMA main.cache_size", in bytes. +** +** If the sorter is running in single-threaded mode, then all PMAs generated +** are appended to a single temporary file. Or, if the sorter is running in +** multi-threaded mode then up to (N+1) temporary files may be opened, where +** N is the configured number of worker threads. In this case, instead of +** sorting the records and writing the PMA to a temporary file itself, the +** calling thread usually launches a worker thread to do so. Except, if +** there are already N worker threads running, the main thread does the work +** itself. +** +** The sorter is running in multi-threaded mode if (a) the library was built +** with pre-processor symbol SQLITE_MAX_WORKER_THREADS set to a value greater +** than zero, and (b) worker threads have been enabled at runtime by calling +** "PRAGMA threads=N" with some value of N greater than 0. +** +** When Rewind() is called, any data remaining in memory is flushed to a +** final PMA. So at this point the data is stored in some number of sorted +** PMAs within temporary files on disk. +** +** If there are fewer than SORTER_MAX_MERGE_COUNT PMAs in total and the +** sorter is running in single-threaded mode, then these PMAs are merged +** incrementally as keys are retreived from the sorter by the VDBE. The +** MergeEngine object, described in further detail below, performs this +** merge. +** +** Or, if running in multi-threaded mode, then a background thread is +** launched to merge the existing PMAs. Once the background thread has +** merged T bytes of data into a single sorted PMA, the main thread +** begins reading keys from that PMA while the background thread proceeds +** with merging the next T bytes of data. And so on. +** +** Parameter T is set to half the value of the memory threshold used +** by Write() above to determine when to create a new PMA. +** +** If there are more than SORTER_MAX_MERGE_COUNT PMAs in total when +** Rewind() is called, then a hierarchy of incremental-merges is used. +** First, T bytes of data from the first SORTER_MAX_MERGE_COUNT PMAs on +** disk are merged together. Then T bytes of data from the second set, and +** so on, such that no operation ever merges more than SORTER_MAX_MERGE_COUNT +** PMAs at a time. This done is to improve locality. +** +** If running in multi-threaded mode and there are more than +** SORTER_MAX_MERGE_COUNT PMAs on disk when Rewind() is called, then more +** than one background thread may be created. Specifically, there may be +** one background thread for each temporary file on disk, and one background +** thread to merge the output of each of the others to a single PMA for +** the main thread to read from. +*/ +/* #include "sqliteInt.h" */ +/* #include "vdbeInt.h" */ + +/* +** If SQLITE_DEBUG_SORTER_THREADS is defined, this module outputs various +** messages to stderr that may be helpful in understanding the performance +** characteristics of the sorter in multi-threaded mode. +*/ +#if 0 +# define SQLITE_DEBUG_SORTER_THREADS 1 +#endif + +/* +** Hard-coded maximum amount of data to accumulate in memory before flushing +** to a level 0 PMA.

These statistics are made available to the query planner +** to help it make better decisions about how to perform queries. +** +** The following system tables are or have been supported: +** +** CREATE TABLE sqlite_stat1(tbl, idx, stat); +** CREATE TABLE sqlite_stat2(tbl, idx, sampleno, sample); +** CREATE TABLE sqlite_stat3(tbl, idx, nEq, nLt, nDLt, sample); +** CREATE TABLE sqlite_stat4(tbl, idx, nEq, nLt, nDLt, sample); +** +** Additional tables might be added in future releases of SQLite. +** The sqlite_stat2 table is not created or used unless the SQLite version +** is between 3.6.18 and 3.7.8, inclusive, and unless SQLite is compiled +** with SQLITE_ENABLE_STAT2. The sqlite_stat2 table is deprecated. +** The sqlite_stat2 table is superseded by sqlite_stat3, which is only +** created and used by SQLite versions 3.7.9 and later and with +** SQLITE_ENABLE_STAT3 defined. The functionality of sqlite_stat3 +** is a superset of sqlite_stat2. The sqlite_stat4 is an enhanced +** version of sqlite_stat3 and is only available when compiled with +** SQLITE_ENABLE_STAT4 and in SQLite versions 3.8.1 and later. It is +** not possible to enable both STAT3 and STAT4 at the same time. If they +** are both enabled, then STAT4 takes precedence. +** +** For most applications, sqlite_stat1 provides all the statistics required +** for the query planner to make good choices. +** +** Format of sqlite_stat1: +** +** There is normally one row per index, with the index identified by the +** name in the idx column. The tbl column is the name of the table to +** which the index belongs. In each such row, the stat column will be +** a string consisting of a list of integers. The first integer in this +** list is the number of rows in the index. (This is the same as the +** number of rows in the table, except for partial indices.) The second +** integer is the average number of rows in the index that have the same +** value in the first column of the index. The third integer is the average +** number of rows in the index that have the same value for the first two +** columns. The N-th integer (for N>1) is the average number of rows in +** the index which have the same value for the first N-1 columns. For +** a K-column index, there will be K+1 integers in the stat column. If +** the index is unique, then the last integer will be 1. +** +** The list of integers in the stat column can optionally be followed +** by the keyword "unordered". The "unordered" keyword, if it is present, +** must be separated from the last integer by a single space. If the +** "unordered" keyword is present, then the query planner assumes that +** the index is unordered and will not use the index for a range query. +** +** If the sqlite_stat1.idx column is NULL, then the sqlite_stat1.stat +** column contains a single integer which is the (estimated) number of +** rows in the table identified by sqlite_stat1.tbl. +** +** Format of sqlite_stat2: +** +** The sqlite_stat2 is only created and is only used if SQLite is compiled +** with SQLITE_ENABLE_STAT2 and if the SQLite version number is between +** 3.6.18 and 3.7.8. The "stat2" table contains additional information +** about the distribution of keys within an index. The index is identified by +** the "idx" column and the "tbl" column is the name of the table to which +** the index belongs. There are usually 10 rows in the sqlite_stat2 +** table for each index. +** +** The sqlite_stat2 entries for an index that have sampleno between 0 and 9 +** inclusive are samples of the left-most key value in the index taken at +** evenly spaced points along the index. Let the number of samples be S +** (10 in the standard build) and let C be the number of rows in the index. +** Then the sampled rows are given by: +** +** rownumber = (i*C*2 + C)/(S*2) +** +** For i between 0 and S-1. Conceptually, the index space is divided into +** S uniform buckets and the samples are the middle row from each bucket. +** +** The format for sqlite_stat2 is recorded here for legacy reference. This +** version of SQLite does not support sqlite_stat2. It neither reads nor +** writes the sqlite_stat2 table. This version of SQLite only supports +** sqlite_stat3. +** +** Format for sqlite_stat3: +** +** The sqlite_stat3 format is a subset of sqlite_stat4. Hence, the +** sqlite_stat4 format will be described first. Further information +** about sqlite_stat3 follows the sqlite_stat4 description. +** +** Format for sqlite_stat4: +** +** As with sqlite_stat2, the sqlite_stat4 table contains histogram data +** to aid the query planner in choosing good indices based on the values +** that indexed columns are compared against in the WHERE clauses of +** queries. +** +** The sqlite_stat4 table contains multiple entries for each index. +** The idx column names the index and the tbl column is the table of the +** index. If the idx and tbl columns are the same, then the sample is +** of the INTEGER PRIMARY KEY. The sample column is a blob which is the +** binary encoding of a key from the index. The nEq column is a +** list of integers. The first integer is the approximate number +** of entries in the index whose left-most column exactly matches +** the left-most column of the sample. The second integer in nEq +** is the approximate number of entries in the index where the +** first two columns match the first two columns of the sample. +** And so forth. nLt is another list of integers that show the approximate +** number of entries that are strictly less than the sample. The first +** integer in nLt contains the number of entries in the index where the +** left-most column is less than the left-most column of the sample. +** The K-th integer in the nLt entry is the number of index entries +** where the first K columns are less than the first K columns of the +** sample. The nDLt column is like nLt except that it contains the +** number of distinct entries in the index that are less than the +** sample. +** +** There can be an arbitrary number of sqlite_stat4 entries per index. +** The ANALYZE command will typically generate sqlite_stat4 tables +** that contain between 10 and 40 samples which are distributed across +** the key space, though not uniformly, and which include samples with +** large nEq values. +** +** Format for sqlite_stat3 redux: +** +** The sqlite_stat3 table is like sqlite_stat4 except that it only +** looks at the left-most column of the index.

TODO: For subqueries without +** A FROM clause, consider adding a FROM close with the special +** table sqlite_once that consists of a single row containing a +** single NULL. +** +** (8) The subquery does not use LIMIT or the outer query is not a join. +** +** (9) The subquery does not use LIMIT or the outer query does not use +** aggregates. +** +** (**) Restriction (10) was removed from the code on 2005-02-05 but we +** accidently carried the comment forward until 2014-09-15.

Subsumed into restriction (3). Was previously +** a separate restriction deriving from ticket #350. +** +** (13) The subquery and outer query do not both use LIMIT. +** +** (14) The subquery does not use OFFSET. +** +** (15) The outer query is not part of a compound select or the +** subquery does not have a LIMIT clause. +** (See ticket #2339 and ticket [02a8e81d44]). +** +** (16) The outer query is not an aggregate or the subquery does +** not contain ORDER BY. (Ticket #2942) This used to not matter +** until we introduced the group_concat() function. +** +** (17) The sub-query is not a compound select, or it is a UNION ALL +** compound clause made up entirely of non-aggregate queries, and +** the parent query: +** +** * is not itself part of a compound select, +** * is not an aggregate or DISTINCT query, and +** * is not a join +** +** The parent and sub-query may contain WHERE clauses. Subject to +** rules (11), (13) and (14), they may also contain ORDER BY, +** LIMIT and OFFSET clauses. The subquery cannot use any compound +** operator other than UNION ALL because all the other compound +** operators have an implied DISTINCT which is disallowed by +** restriction (4). +** +** Also, each component of the sub-query must return the same number +** of result columns. This is actually a requirement for any compound +** SELECT statement, but all the code here does is make sure that no +** such (illegal) sub-query is flattened. The caller will detect the +** syntax error and return a detailed message. +** +** (18) If the sub-query is a compound select, then all terms of the +** ORDER by clause of the parent must be simple references to +** columns of the sub-query. +** +** (19) The subquery does not use LIMIT or the outer query does not +** have a WHERE clause. +** +** (20) If the sub-query is a compound select, then it must not use +** an ORDER BY clause. Ticket #3773. We could relax this constraint +** somewhat by saying that the terms of the ORDER BY clause must +** appear as unmodified result columns in the outer query. But we +** have other optimizations in mind to deal with that case. +** +** (21) The subquery does not use LIMIT or the outer query is not +** DISTINCT.

Note also that when the IN operator appears in +** the WHERE clause, it might result in additional nested loops for +** scanning through all values on the right-hand side of the IN. +** +** There are Btree cursors associated with each table. t1 uses cursor +** number pTabList->a[0].iCursor. t2 uses the cursor pTabList->a[1].iCursor. +** And so forth. This routine generates code to open those VDBE cursors +** and sqlite3WhereEnd() generates the code to close them. +** +** The code that sqlite3WhereBegin() generates leaves the cursors named +** in pTabList pointing at their appropriate entries. The [...] code +** can use OP_Column and OP_Rowid opcodes on these cursors to extract +** data from the various tables of the loop. +** +** If the WHERE clause is empty, the foreach loops must each scan their +** entire tables. Thus a three-way join is an O(N^3) operation. But if +** the tables have indices and there are terms in the WHERE clause that +** refer to those indices, a complete table scan can be avoided and the +** code will run much faster. Most of the work of this routine is checking +** to see if there are indices that can be used to speed up the loop. +** +** Terms of the WHERE clause are also used to limit which rows actually +** make it to the "..." in the middle of the loop.

Larger types otherwise. +** YYNOCODE is a number of type YYCODETYPE that is not used for +** any terminal or nonterminal symbol. +** YYFALLBACK If defined, this indicates that one or more tokens +** (also known as: "terminal symbols") have fall-back +** values which should be used if the original symbol +** would not parse. This permits keywords to sometimes +** be used as identifiers, for example. +** YYACTIONTYPE is the data type used for "action codes" - numbers +** that indicate what to do in response to the next +** token. +** sqlite3ParserTOKENTYPE is the data type used for minor type for terminal +** symbols. Background: A "minor type" is a semantic +** value associated with a terminal or non-terminal +** symbols. For example, for an "ID" terminal symbol, +** the minor type might be the name of the identifier. +** Each non-terminal can have a different minor type. +** Terminal symbols all have the same minor type, though. +** This macros defines the minor type for terminal +** symbols. +** YYMINORTYPE is the data type used for all minor types. +** This is typically a union of many types, one of +** which is sqlite3ParserTOKENTYPE.

SQLite varints are big-endian +** are are limited to 9 bytes in length whereas FTS3 varints are +** little-endian and can be up to 10 bytes in length (in theory). +** +** Example encodings: +** +** 1: 0x01 +** 127: 0x7f +** 128: 0x81 0x00 +** +** +**** Document lists **** +** A doclist (document list) holds a docid-sorted list of hits for a +** given term. Doclists hold docids and associated token positions. +** A docid is the unique integer identifier for a single document. +** A position is the index of a word within the document. The first +** word of the document has a position of 0. +** +** FTS3 used to optionally store character offsets using a compile-time +** option. But that functionality is no longer supported. +** +** A doclist is stored like this: +** +** array { +** varint docid; (delta from previous doclist) +** array { (position list for column 0) +** varint position; (2 more than the delta from previous position) +** } +** array { +** varint POS_COLUMN; (marks start of position list for new column) +** varint column; (index of new column) +** array { +** varint position; (2 more than the delta from previous position) +** } +** } +** varint POS_END; (marks end of positions for this document. +** } +** +** Here, array { X } means zero or more occurrences of X, adjacent in +** memory. A "position" is an index of a token in the token stream +** generated by the tokenizer. Note that POS_END and POS_COLUMN occur +** in the same logical place as the position element, and act as sentinals +** ending a position list array. POS_END is 0. POS_COLUMN is 1. +** The positions numbers are not stored literally but rather as two more +** than the difference from the prior position, or the just the position plus +** 2 for the first position. Example: +** +** label: A B C D E F G H I J K +** value: 123 5 9 1 1 14 35 0 234 72 0 +** +** The 123 value is the first docid. For column zero in this document +** there are two matches at positions 3 and 10 (5-2 and 9-2+3). The 1 +** at D signals the start of a new column; the 1 at E indicates that the +** new column is column number 1. There are two positions at 12 and 45 +** (14-2 and 35-2+12). The 0 at H indicate the end-of-document. The +** 234 at I is the delta to next docid (357). It has one position 70 +** (72-2) and then terminates with the 0 at K. +** +** A "position-list" is the list of positions for multiple columns for +** a single docid. A "column-list" is the set of positions for a single +** column. Hence, a position-list consists of one or more column-lists, +** a document record consists of a docid followed by a position-list and +** a doclist consists of one or more document records. +** +** A bare doclist omits the position information, becoming an +** array of varint-encoded docids. +** +**** Segment leaf nodes **** +** Segment leaf nodes store terms and doclists, ordered by term. Leaf +** nodes are written using LeafWriter, and read using LeafReader (to +** iterate through a single leaf node's data) and LeavesReader (to +** iterate through a segment's entire leaf layer). Leaf nodes have +** the format: +** +** varint iHeight; (height from leaf level, always 0) +** varint nTerm; (length of first term) +** char pTerm[nTerm]; (content of first term) +** varint nDoclist; (length of term's associated doclist) +** char pDoclist[nDoclist]; (content of doclist) +** array { +** (further terms are delta-encoded) +** varint nPrefix; (length of prefix shared with previous term) +** varint nSuffix; (length of unshared suffix) +** char pTermSuffix[nSuffix];(unshared suffix of next term) +** varint nDoclist; (length of term's associated doclist) +** char pDoclist[nDoclist]; (content of doclist) +** } +** +** Here, array { X } means zero or more occurrences of X, adjacent in +** memory. +** +** Leaf nodes are broken into blocks which are stored contiguously in +** the %_segments table in sorted order. This means that when the end +** of a node is reached, the next term is in the node with the next +** greater node id. +** +** New data is spilled to a new leaf node when the current node +** exceeds LEAF_MAX bytes (default 2048). New data which itself is +** larger than STANDALONE_MIN (default 1024) is placed in a standalone +** node (a leaf node with a single term and doclist). The goal of +** these settings is to pack together groups of small doclists while +** making it efficient to directly access large doclists. The +** assumption is that large doclists represent terms which are more +** likely to be query targets. +** +** TODO(shess) It may be useful for blocking decisions to be more +** dynamic. For instance, it may make more sense to have a 2.5k leaf +** node rather than splitting into 2k and .5k nodes. My intuition is +** that this might extend through 2x or 4x the pagesize. +** +** +**** Segment interior nodes **** +** Segment interior nodes store blockids for subtree nodes and terms +** to describe what data is stored by the each subtree. Interior +** nodes are written using InteriorWriter, and read using +** InteriorReader. InteriorWriters are created as needed when +** SegmentWriter creates new leaf nodes, or when an interior node +** itself grows too big and must be split. The format of interior +** nodes: +** +** varint iHeight; (height from leaf level, always >0) +** varint iBlockid; (block id of node's leftmost subtree) +** optional { +** varint nTerm; (length of first term) +** char pTerm[nTerm]; (content of first term) +** array { +** (further terms are delta-encoded) +** varint nPrefix; (length of shared prefix with previous term) +** varint nSuffix; (length of unshared suffix) +** char pTermSuffix[nSuffix]; (unshared suffix of next term) +** } +** } +** +** Here, optional { X } means an optional element, while array { X } +** means zero or more occurrences of X, adjacent in memory. +** +** An interior node encodes n terms separating n+1 subtrees. The +** subtree blocks are contiguous, so only the first subtree's blockid +** is encoded. The subtree at iBlockid will contain all terms less +** than the first term encoded (or all terms if no term is encoded). +** Otherwise, for terms greater than or equal to pTerm[i] but less +** than pTerm[i+1], the subtree for that term will be rooted at +** iBlockid+i. Interior nodes only store enough term data to +** distinguish adjacent children (if the rightmost term of the left +** child is "something", and the leftmost term of the right child is +** "wicked", only "w" is stored). +** +** New data is spilled to a new interior node at the same height when +** the current node exceeds INTERIOR_MAX bytes (default 2048). +** INTERIOR_MIN_TERMS (default 7) keeps large terms from monopolizing +** interior nodes and making the tree too skinny. The interior nodes +** at a given height are naturally tracked by interior nodes at +** height+1, and so on. +** +** +**** Segment directory **** +** The segment directory in table %_segdir stores meta-information for +** merging and deleting segments, and also the root node of the +** segment's tree. +** +** The root node is the top node of the segment's tree after encoding +** the entire segment, restricted to ROOT_MAX bytes (default 1024). +** This could be either a leaf node or an interior node. If the top +** node requires more than ROOT_MAX bytes, it is flushed to %_segments +** and a new root interior node is generated (which should always fit +** within ROOT_MAX because it only needs space for 2 varints, the +** height and the blockid of the previous root). +** +** The meta-information in the segment directory is: +** level - segment level (see below) +** idx - index within level +** - (level,idx uniquely identify a segment) +** start_block - first leaf node +** leaves_end_block - last leaf node +** end_block - last block (including interior nodes) +** root - contents of root node +** +** If the root node is a leaf node, then start_block, +** leaves_end_block, and end_block are all 0. +** +** +**** Segment merging **** +** To amortize update costs, segments are grouped into levels and +** merged in batches. Each increase in level represents exponentially +** more documents. +** +** New documents (actually, document updates) are tokenized and +** written individually (using LeafWriter) to a level 0 segment, with +** incrementing idx. When idx reaches MERGE_COUNT (default 16), all +** level 0 segments are merged into a single level 1 segment. Level 1 +** is populated like level 0, and eventually MERGE_COUNT level 1 +** segments are merged to a single level 2 segment (representing +** MERGE_COUNT^2 updates), and so on. +** +** A segment merge traverses all segments at a given level in +** parallel, performing a straightforward sorted merge. Since segment +** leaf nodes are written in to the %_segments table in order, this +** merge traverses the underlying sqlite disk structures efficiently. +** After the merge, all segment blocks from the merged level are +** deleted. +** +** MERGE_COUNT controls how often we merge segments. 16 seems to be +** somewhat of a sweet spot for insertion performance. 32 and 64 show +** very similar performance numbers to 16 on insertion, though they're +** a tiny bit slower (perhaps due to more overhead in merge-time +** sorting). 8 is about 20% slower than 16, 4 about 50% slower than +** 16, 2 about 66% slower than 16. +** +** At query time, high MERGE_COUNT increases the number of segments +** which need to be scanned and merged. For instance, with 100k docs +** inserted: +** +** MERGE_COUNT segments +** 16 25 +** 8 12 +** 4 10 +** 2 6 +** +** This appears to have only a moderate impact on queries for very +** frequent terms (which are somewhat dominated by segment merge +** costs), and infrequent and non-existent terms still seem to be fast +** even with many segments. +** +** TODO(shess) That said, it would be nice to have a better query-side +** argument for MERGE_COUNT of 16. Also, it is possible/likely that +** optimizations to things like doclist merging will swing the sweet +** spot around. +** +** +** +**** Handling of deletions and updates **** +** Since we're using a segmented structure, with no docid-oriented +** index into the term index, we clearly cannot simply update the term +** index when a document is deleted or updated. For deletions, we +** write an empty doclist (varint(docid) varint(POS_END)), for updates +** we simply write the new doclist. Segment merges overwrite older +** data for a particular docid with newer data, so deletes or updates +** will eventually overtake the earlier data and knock it out. The +** query logic likewise merges doclists so that newer data knocks out +** older data. +*/ + +/************** Include fts3Int.h in the middle of fts3.c ********************/ +/************** Begin file fts3Int.h *****************************************/ +/* +** 2009 Nov 12 +** +** The author disclaims copyright to this source code.

The tables it expects to find are described in +** sqlite3rbu.h. Essentially, for each table xyz in the target database +** that the user wishes to write to, a corresponding data_xyz table is +** created in the RBU database and populated with one row for each row to +** update, insert or delete from the target table. +** +** The update proceeds in three stages: +** +** 1) The database is updated. The modified database pages are written +** to a *-oal file. A *-oal file is just like a *-wal file, except +** that it is named "-oal" instead of "-wal". +** Because regular SQLite clients do not look for file named +** "-oal", they go on using the original database in +** rollback mode while the *-oal file is being generated. +** +** During this stage RBU does not update the database by writing +** directly to the target tables. Instead it creates "imposter" +** tables using the SQLITE_TESTCTRL_IMPOSTER interface that it uses +** to update each b-tree individually. All updates required by each +** b-tree are completed before moving on to the next, and all +** updates are done in sorted key order. +** +** 2) The "-oal" file is moved to the equivalent "-wal" +** location using a call to rename(2). Before doing this the RBU +** module takes an EXCLUSIVE lock on the database file, ensuring +** that there are no other active readers. +** +** Once the EXCLUSIVE lock is released, any other database readers +** detect the new *-wal file and read the database in wal mode. At +** this point they see the new version of the database - including +** the updates made as part of the RBU update. +** +** 3) The new *-wal file is checkpointed. This proceeds in the same way +** as a regular database checkpoint, except that a single frame is +** checkpointed each time sqlite3rbu_step() is called. If the RBU +** handle is closed before the entire *-wal file is checkpointed, +** the checkpoint progress is saved in the RBU database and the +** checkpoint can be resumed by another RBU client at some point in +** the future. +** +** POTENTIAL PROBLEMS +** +** The rename() call might not be portable. And RBU is not currently +** syncing the directory after renaming the file. +** +** When state is saved, any commit to the *-oal file and the commit to +** the RBU update database are not atomic. So if the power fails at the +** wrong moment they might get out of sync. As the main database will be +** committed before the RBU update database this will likely either just +** pass unnoticed, or result in SQLITE_CONSTRAINT errors (due to UNIQUE +** constraint violations). +** +** If some client does modify the target database mid RBU update, or some +** other error occurs, the RBU extension will keep throwing errors. It's +** not really clear how to get out of this state. The system could just +** by delete the RBU update database and *-oal file and have the device +** download the update again and start over. +** +** At present, for an UPDATE, both the new.* and old.* records are +** collected in the rbu_xyz table. And for both UPDATEs and DELETEs all +** fields are collected. This means we're probably writing a lot more +** data to disk when saving the state of an ongoing update to the RBU +** update database than is strictly necessary. +** +*/ + +/* #include */ +/* #include */ +/* #include */ + +/* #include "sqlite3.h" */ + +#if !defined(SQLITE_CORE) || defined(SQLITE_ENABLE_RBU) +/************** Include sqlite3rbu.h in the middle of sqlite3rbu.c ***********/ +/************** Begin file sqlite3rbu.h **************************************/ +/* +** 2014 August 30 +** +** The author disclaims copyright to this source code.

If the +** working set of leaves is larger than the available cache memory, then a +** single leaf that is modified more than once as part of the transaction +** may be loaded from or written to the persistent media multiple times. +** Additionally, because the index updates are likely to be applied in +** random order, access to pages within the database is also likely to be in +** random order, which is itself quite inefficient. +** +** One way to improve the situation is to sort the operations on each index +** by index key before applying them to the b-tree. This leads to an IO +** pattern that resembles a single linear scan through the index b-tree, +** and all but guarantees each modified leaf page is loaded and stored +** exactly once. SQLite uses this trick to improve the performance of +** CREATE INDEX commands. This extension allows it to be used to improve +** the performance of large transactions on existing databases. +** +** Additionally, this extension allows the work involved in writing the +** large transaction to be broken down into sub-transactions performed +** sequentially by separate processes. This is useful if the system cannot +** guarantee that a single update process will run for long enough to apply +** the entire update, for example because the update is being applied on a +** mobile device that is frequently rebooted. Even after the writer process +** has committed one or more sub-transactions, other database clients continue +** to read from the original database snapshot. In other words, partially +** applied transactions are not visible to other clients. +** +** "RBU" stands for "Resumable Bulk Update". As in a large database update +** transmitted via a wireless network to a mobile device. A transaction +** applied using this extension is hence refered to as an "RBU update". +** +** +** LIMITATIONS +** +** An "RBU update" transaction is subject to the following limitations: +** +** * The transaction must consist of INSERT, UPDATE and DELETE operations +** only. +** +** * INSERT statements may not use any default values. +** +** * UPDATE and DELETE statements must identify their target rows by +** non-NULL PRIMARY KEY values. Rows with NULL values stored in PRIMARY +** KEY fields may not be updated or deleted. If the table being written +** has no PRIMARY KEY, affected rows must be identified by rowid. +** +** * UPDATE statements may not modify PRIMARY KEY columns. +** +** * No triggers will be fired. +** +** * No foreign key violations are detected or reported. +** +** * CHECK constraints are not enforced. +** +** * No constraint handling mode except for "OR ROLLBACK" is supported. +** +** +** PREPARATION +** +** An "RBU update" is stored as a separate SQLite database. A database +** containing an RBU update is an "RBU database". For each table in the +** target database to be updated, the RBU database should contain a table +** named "data_" containing the same set of columns as the +** target table, and one more - "rbu_control". The data_% table should +** have no PRIMARY KEY or UNIQUE constraints, but each column should have +** the same type as the corresponding column in the target database. +** The "rbu_control" column should have no type at all. For example, if +** the target database contains: +** +** CREATE TABLE t1(a INTEGER PRIMARY KEY, b TEXT, c UNIQUE); +** +** Then the RBU database should contain: +** +** CREATE TABLE data_t1(a INTEGER, b TEXT, c, rbu_control); +** +** The order of the columns in the data_% table does not matter. +** +** Instead of a regular table, the RBU database may also contain virtual +** tables or view named using the data_ naming scheme. +** +** Instead of the plain data_ naming scheme, RBU database tables +** may also be named data_, where is any sequence +** of zero or more numeric characters (0-9). This can be significant because +** tables within the RBU database are always processed in order sorted by +** name. By judicious selection of the the portion of the names +** of the RBU tables the user can therefore control the order in which they +** are processed. This can be useful, for example, to ensure that "external +** content" FTS4 tables are updated before their underlying content tables. +** +** If the target database table is a virtual table or a table that has no +** PRIMARY KEY declaration, the data_% table must also contain a column +** named "rbu_rowid". This column is mapped to the tables implicit primary +** key column - "rowid". Virtual tables for which the "rowid" column does +** not function like a primary key value cannot be updated using RBU. For +** example, if the target db contains either of the following: +** +** CREATE VIRTUAL TABLE x1 USING fts3(a, b); +** CREATE TABLE x1(a, b) +** +** then the RBU database should contain: +** +** CREATE TABLE data_x1(a, b, rbu_rowid, rbu_control); +** +** All non-hidden columns (i.e. all columns matched by "SELECT *") of the +** target table must be present in the input table. For virtual tables, +** hidden columns are optional - they are updated by RBU if present in +** the input table, or not otherwise. For example, to write to an fts4 +** table with a hidden languageid column such as: +** +** CREATE VIRTUAL TABLE ft1 USING fts4(a, b, languageid='langid'); +** +** Either of the following input table schemas may be used: +** +** CREATE TABLE data_ft1(a, b, langid, rbu_rowid, rbu_control); +** CREATE TABLE data_ft1(a, b, rbu_rowid, rbu_control); +** +** For each row to INSERT into the target database as part of the RBU +** update, the corresponding data_% table should contain a single record +** with the "rbu_control" column set to contain integer value 0. The +** other columns should be set to the values that make up the new record +** to insert. +** +** If the target database table has an INTEGER PRIMARY KEY, it is not +** possible to insert a NULL value into the IPK column. Attempting to +** do so results in an SQLITE_MISMATCH error. +** +** For each row to DELETE from the target database as part of the RBU +** update, the corresponding data_% table should contain a single record +** with the "rbu_control" column set to contain integer value 1. The +** real primary key values of the row to delete should be stored in the +** corresponding columns of the data_% table. The values stored in the +** other columns are not used. +** +** For each row to UPDATE from the target database as part of the RBU +** update, the corresponding data_% table should contain a single record +** with the "rbu_control" column set to contain a value of type text. +** The real primary key values identifying the row to update should be +** stored in the corresponding columns of the data_% table row, as should +** the new values of all columns being update. The text value in the +** "rbu_control" column must contain the same number of characters as +** there are columns in the target database table, and must consist entirely +** of 'x' and '.' characters (or in some special cases 'd' - see below). For +** each column that is being updated, the corresponding character is set to +** 'x'. For those that remain as they are, the corresponding character of the +** rbu_control value should be set to '.'. For example, given the tables +** above, the update statement: +** +** UPDATE t1 SET c = 'usa' WHERE a = 4; +** +** is represented by the data_t1 row created by: +** +** INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..x'); +** +** Instead of an 'x' character, characters of the rbu_control value specified +** for UPDATEs may also be set to 'd'. In this case, instead of updating the +** target table with the value stored in the corresponding data_% column, the +** user-defined SQL function "rbu_delta()" is invoked and the result stored in +** the target table column. rbu_delta() is invoked with two arguments - the +** original value currently stored in the target table column and the +** value specified in the data_xxx table. +** +** For example, this row: +** +** INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..d'); +** +** is similar to an UPDATE statement such as: +** +** UPDATE t1 SET c = rbu_delta(c, 'usa') WHERE a = 4; +** +** Finally, if an 'f' character appears in place of a 'd' or 's' in an +** ota_control string, the contents of the data_xxx table column is assumed +** to be a "fossil delta" - a patch to be applied to a blob value in the +** format used by the fossil source-code management system. In this case +** the existing value within the target database table must be of type BLOB. +** It is replaced by the result of applying the specified fossil delta to +** itself. +** +** If the target database table is a virtual table or a table with no PRIMARY +** KEY, the rbu_control value should not include a character corresponding +** to the rbu_rowid value. For example, this: +** +** INSERT INTO data_ft1(a, b, rbu_rowid, rbu_control) +** VALUES(NULL, 'usa', 12, '.x'); +** +** causes a result similar to: +** +** UPDATE ft1 SET b = 'usa' WHERE rowid = 12; +** +** The data_xxx tables themselves should have no PRIMARY KEY declarations. +** However, RBU is more efficient if reading the rows in from each data_xxx +** table in "rowid" order is roughly the same as reading them sorted by +** the PRIMARY KEY of the corresponding target database table. In other +** words, rows should be sorted using the destination table PRIMARY KEY +** fields before they are inserted into the data_xxx tables. +** +** USAGE +** +** The API declared below allows an application to apply an RBU update +** stored on disk to an existing target database. Essentially, the +** application: +** +** 1) Opens an RBU handle using the sqlite3rbu_open() function. +** +** 2) Registers any required virtual table modules with the database +** handle returned by sqlite3rbu_db(). Also, if required, register +** the rbu_delta() implementation. +** +** 3) Calls the sqlite3rbu_step() function one or more times on +** the new handle. Each call to sqlite3rbu_step() performs a single +** b-tree operation, so thousands of calls may be required to apply +** a complete update. +** +** 4) Calls sqlite3rbu_close() to close the RBU update handle. If +** sqlite3rbu_step() has been called enough times to completely +** apply the update to the target database, then the RBU database +** is marked as fully applied. Otherwise, the state of the RBU +** update application is saved in the RBU database for later +** resumption. +** +** See comments below for more detail on APIs. +** +** If an update is only partially applied to the target database by the +** time sqlite3rbu_close() is called, various state information is saved +** within the RBU database.
