Each time such an extension occurs, the iVersion field // is incremented. The iVersion value started out as 1 in // SQLite [version 3.5.0] on [dateof:3.5.0], then increased to 2 // with SQLite [version 3.7.0] on [dateof:3.7.0], and then increased // to 3 with SQLite [version 3.7.6] on [dateof:3.7.6]. Additional fields // may be appended to the sqlite3_vfs object and the iVersion value // may increase again in future versions of SQLite. // Note that due to an oversight, the structure // of the sqlite3_vfs object changed in the transition from // SQLite [version 3.5.9] to [version 3.6.0] on [dateof:3.6.0] // and yet the iVersion field was not increased. // // 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. The [sqlite3_vfs_register()] // and [sqlite3_vfs_unregister()] interfaces manage this list // in a thread-safe way. The [sqlite3_vfs_find()] interface // searches the list. Neither the application code nor the VFS // implementation should use the pNext pointer. // // The pNext field is the only field in the sqlite3_vfs // structure that SQLite will ever modify. SQLite will only access // or modify this field while holding a particular static mutex. // The application should never modify anything within the sqlite3_vfs // object once the object has been registered. // // The zName field holds the name of the VFS module. The name must // be unique across all VFS modules. // // [[sqlite3_vfs.xOpen]] // ^SQLite guarantees that the zFilename parameter to xOpen // is either a NULL pointer or string obtained // from xFullPathname() with an optional suffix added. // ^If a suffix is added to the zFilename parameter, it will // consist of a single "-" character followed by no more than // 11 alphanumeric and/or "-" characters. // ^SQLite further guarantees that // the string will be valid and unchanged until xClose() is // called. Because of the previous sentence, // the [sqlite3_file] can safely store a pointer to the // filename if it needs to remember the filename for some reason. // If the zFilename parameter to xOpen is a NULL pointer then xOpen // must invent its own temporary name for the file. ^Whenever the // xFilename parameter is NULL it will also be the case that the // flags parameter will include [SQLITE_OPEN_DELETEONCLOSE]. // // The flags argument to xOpen() includes all bits set in // the flags argument to [sqlite3_open_v2()]. Or if [sqlite3_open()] // or [sqlite3_open16()] is used, then flags includes at least // [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE]. // If xOpen() opens a file read-only then it sets *pOutFlags to // include [SQLITE_OPEN_READONLY]. Other bits in *pOutFlags may be set. // // ^(SQLite will also add one of the following flags to the xOpen() // call, depending on the object being opened: // // )^ // // The file I/O implementation can use the object type flags to // change the way it deals with files. For example, an application // that does not care about crash recovery or rollback might make // the open of a journal file a no-op. Writes to this journal would // also be no-ops, and any attempt to read the journal would return // SQLITE_IOERR. Or the implementation might recognize that a database // file will be doing page-aligned sector reads and writes in a random // order and set up its I/O subsystem accordingly. // // SQLite might also add one of the following flags to the xOpen method: // // // // 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 xOpen method does not have to // allocate the structure; it should just fill it in. Note that // the xOpen method must set the sqlite3_file.pMethods to either // a valid [sqlite3_io_methods] object or to NULL. xOpen must do // this even if the open fails. SQLite expects that the sqlite3_file.pMethods // element will be valid after xOpen returns regardless of the success // or failure of the xOpen call. // // [[sqlite3_vfs.xAccess]] // ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS] // to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to // test whether a file is readable and writable, or [SQLITE_ACCESS_READ] // to test whether a file is at least readable. The SQLITE_ACCESS_READ // flag is never actually used and is not implemented in the built-in // VFSes of SQLite. The file is named by the second argument and can be a // directory. The xAccess method returns [SQLITE_OK] on success or some // non-zero error code if there is an I/O error or if the name of // the file given in the second argument is illegal. If SQLITE_OK // is returned, then non-zero or zero is written into *pResOut to indicate // whether or not the file is accessible. // // ^SQLite will always allocate at least mxPathname+1 bytes for the // output buffer xFullPathname. The exact size of the output buffer // is also passed as a parameter to both methods. If the output buffer // is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is // handled as a fatal error by SQLite, vfs implementations should endeavor // to prevent this by setting mxPathname to a sufficiently large value. // // The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64() // interfaces are not strictly a part of the filesystem, but they are // included in the VFS structure for completeness. // The xRandomness() function attempts to return nBytes bytes // of good-quality randomness into zOut. 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. These optional interfaces are provided // by some VFSes to facilitate testing of the VFS code. By overriding // system calls with functions under its control, a test program can // simulate faults and error conditions that would otherwise be difficult // or impossible to induce. The set of system calls that can be overridden // varies from one VFS to another, and from one version of the same VFS to the // next. Applications that use these interfaces must be prepared for any // or all of these interfaces to be NULL or for their behavior to change // from one release to the next.

If we assume that writing a // single disk sector is atomic, then this mode provides // assurance that the journal will not be corrupted to the // point of causing damage to the database during rollback. // // EXTRA This is like FULL except that is also syncs the directory // that contains the rollback journal after the rollback // journal is unlinked. // // The above is for a rollback-journal mode. For WAL mode, OFF continues // to mean that no syncs ever occur. NORMAL means that the WAL is synced // prior to the start of checkpoint and that the database file is synced // at the conclusion of the checkpoint if the entire content of the WAL // was written back into the database. But no sync operations occur for // an ordinary commit in NORMAL mode with WAL.

structure that contains // information needed to terminate the loop. Later, the calling routine // should invoke sqlite3WhereEnd() with the return value of this function // in order to complete the WHERE clause processing. // // If an error occurs, this routine returns NULL. // // The basic idea is to do a nested loop, one loop for each table in // the FROM clause of a select. (INSERT and UPDATE statements are the // same as a SELECT with only a single table in the FROM clause.) For // example, if the SQL is this: // // SELECT * FROM t1, t2, t3 WHERE ...; // // Then the code generated is conceptually like the following: // // foreach row1 in t1 do \ Code generated // foreach row2 in t2 do |-- by sqlite3WhereBegin() // foreach row3 in t3 do / // ... // end \ Code generated // end |-- by sqlite3WhereEnd() // end / // // Note that the loops might not be nested in the order in which they // appear in the FROM clause if a different order is better able to make // use of indices. 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. After each "foreach", // terms of the WHERE clause that use only terms in that loop and outer // loops are evaluated and if false a jump is made around all subsequent // inner loops (or around the "..." if the test occurs within the inner- // most loop) // // # OUTER JOINS // // An outer join of tables t1 and t2 is conceptally coded as follows: // // foreach row1 in t1 do // flag = 0 // foreach row2 in t2 do // start: // ... // flag = 1 // end // if flag==0 then // move the row2 cursor to a null row // goto start // fi // end // // # ORDER BY CLAUSE PROCESSING // // pOrderBy is a pointer to the ORDER BY clause (or the GROUP BY clause // if the WHERE_GROUPBY flag is set in wctrlFlags) of a SELECT statement // if there is one. If there is no ORDER BY clause or if this routine // is called from an UPDATE or DELETE statement, then pOrderBy is NULL. // // The iIdxCur parameter is the cursor number of an index. If // WHERE_OR_SUBCLAUSE is set, iIdxCur is the cursor number of an index // to use for OR clause processing. The WHERE clause should use this // specific cursor.

The only // exceptional case is: // // ROWS BETWEEN FOLLOWING AND UNBOUNDED FOLLOWING // // ... loop started by sqlite3WhereBegin() ... // if( new partition ){ // Gosub flush // } // Insert new row into eph table. // if( first row of partition ){ // Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent) // regStart = // }else{ // AGGSTEP // } // } // flush: // AGGSTEP // while( 1 ){ // if( (regStart--)<=0 ){ // AGGINVERSE // if( eof ) break // } // RETURN_ROW // } // while( !eof csrCurrent ){ // RETURN_ROW // } // // Also requiring special handling are the cases: // // ROWS BETWEEN PRECEDING AND PRECEDING // ROWS BETWEEN FOLLOWING AND FOLLOWING // // when (expr1 < expr2). This is detected at runtime, not by this function. // To handle this case, the pseudo-code programs depicted above are modified // slightly to be: // // ... loop started by sqlite3WhereBegin() ... // if( new partition ){ // Gosub flush // } // Insert new row into eph table. // if( first row of partition ){ // Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent) // regEnd = // regStart = // if( regEnd < regStart ){ // RETURN_ROW // delete eph table contents // continue // } // ... // // The new "continue" statement in the above jumps to the next iteration // of the outer loop - the one started by sqlite3WhereBegin(). // // The various GROUPS cases are implemented using the same patterns as // ROWS. The VM code is modified slightly so that: // // 1. The else branch in the main loop is only taken if the row just // added to the ephemeral table is the start of a new group. In // other words, it becomes: // // ... loop started by sqlite3WhereBegin() ... // if( new partition ){ // Gosub flush // } // Insert new row into eph table. // if( first row of partition ){ // Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent) // regEnd = // regStart = // }else if( new group ){ // ... // } // } // // 2. Instead of processing a single row, each RETURN_ROW, AGGSTEP or // AGGINVERSE step processes the current row of the relevant cursor and // all subsequent rows belonging to the same group. // // RANGE window frames are a little different again. As for GROUPS, the // main loop runs once per group only. And RETURN_ROW, AGGSTEP and AGGINVERSE // deal in groups instead of rows. As for ROWS and GROUPS, there are three // basic cases: // // RANGE BETWEEN PRECEDING AND FOLLOWING // // ... loop started by sqlite3WhereBegin() ... // if( new partition ){ // Gosub flush // } // Insert new row into eph table. // if( first row of partition ){ // Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent) // regEnd = // regStart = // }else{ // AGGSTEP // while( (csrCurrent.key + regEnd) < csrEnd.key ){ // RETURN_ROW // while( csrStart.key + regStart) < csrCurrent.key ){ // AGGINVERSE // } // } // } // } // flush: // AGGSTEP // while( 1 ){ // RETURN ROW // if( csrCurrent is EOF ) break; // while( csrStart.key + regStart) < csrCurrent.key ){ // AGGINVERSE // } // } // } // // In the above notation, "csr.key" means the current value of the ORDER BY // expression (there is only ever 1 for a RANGE that uses an FOLLOWING // or PRECEDING AND PRECEDING // // ... loop started by sqlite3WhereBegin() ... // if( new partition ){ // Gosub flush // } // Insert new row into eph table. // if( first row of partition ){ // Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent) // regEnd = // regStart = // }else{ // while( (csrEnd.key + regEnd) <= csrCurrent.key ){ // AGGSTEP // } // while( (csrStart.key + regStart) < csrCurrent.key ){ // AGGINVERSE // } // RETURN_ROW // } // } // flush: // while( (csrEnd.key + regEnd) <= csrCurrent.key ){ // AGGSTEP // } // while( (csrStart.key + regStart) < csrCurrent.key ){ // AGGINVERSE // } // RETURN_ROW // // RANGE BETWEEN FOLLOWING AND FOLLOWING // // ... loop started by sqlite3WhereBegin() ... // if( new partition ){ // Gosub flush // } // Insert new row into eph table. // if( first row of partition ){ // Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent) // regEnd = // regStart = // }else{ // AGGSTEP // while( (csrCurrent.key + regEnd) < csrEnd.key ){ // while( (csrCurrent.key + regStart) > csrStart.key ){ // AGGINVERSE // } // RETURN_ROW // } // } // } // flush: // AGGSTEP // while( 1 ){ // while( (csrCurrent.key + regStart) > csrStart.key ){ // AGGINVERSE // if( eof ) break "while( 1 )" loop. // } // RETURN_ROW // } // while( !eof csrCurrent ){ // RETURN_ROW // } // // The text above leaves out many details.
