Original commit message from CVS:
Fix parsing of negative numbers. Note that parsing of floating point
numbers is broken in exponential form (1.0e6 or 1.0E6).
Original commit message from CVS:
- A regular seek event sets the endoffset to -1 to indicate
that the value should be ignored.
- A segment seek only takes start < stop
Original commit message from CVS:
After the third time of calling GST_PROPS_FLOAT with an integer and
wondering why it didn't work, I add an explicit cast.
Original commit message from CVS:
the big autoplag coverup plus some further cleaning.
Can someone tell me if this change violates some sort of API stability, or
was this meant to be an internal function anyway (and thus should it be
somehow removed from the .h) ?
Original commit message from CVS:
Add -p and -P flags to bison and flex, to prefix yy* symbols with
_gst_parse_yy. This fixes symbol conflict with other libs.
(Should go into 0.4.1.)
Original commit message from CVS:
Fix for compiler warnings on PowerPC. Compiler complains about longjmp()
clobbering local variables, which appear to be bogus.
Original commit message from CVS:
- Added value transform functions for caps and props boxed types
- implement gst_props_new with a GList
- fixed silly typo in _gst_type_*
Original commit message from CVS:
- some cleanups
- revert a patch that needs more thinking..
- move common code and sanity checks in gstscheduler.c instead of the
real schedulers.
- remove sanity checks from the schedulers
Original commit message from CVS:
- Make the return GList of gst_element_get_pad_list as const
- Pad scheduler refactoring
- Remove gst_pad_set/unset_scheduler as it's not needed
- Reimplement gst_pad_get_scheduler using the parent scheduler
- Remove gst_pad_peek as it cannot work reliably
- Remove the pad bufpen, replace with scheduler private gpointer
- Make queue use the new _get_scheduler implementation
- Remove _pad_unset_scheduler from GstScheduler
- Remove LOOP_SEEK mode from aggregator
- Other fixes for API changes.
Original commit message from CVS:
This changes an important part of the plugin API, gst_pad_try_set_caps() no longer returns a boolean, it now returns a GstPadConnectReturn, which makes much more sense than a boolean. All plugins have also been changed, so don't worry ;)
Original commit message from CVS:
big ass set of useless dog fixes [1]
changes to pad code so that NULL names are allowed and useful [1]
some API changes [2]
lots of code cleanup
[1] approved by wtay [3]
[2] approved by wingo
[3] how long can we keep blaming that code guy that's not back from holidays
yet for everything we commit ?
Original commit message from CVS:
fixes bug
http://bugzilla.gnome.org/show_bug.cgi?id=90333
and similar.
I'd like to also do s/guchar/gchar/ in the xml functions, any reason not to ?
please comment ;)
Original commit message from CVS:
Some more event flags
some more padquery types
Better debugging in _pad_get_caps
ref the caps before adding them to a padtemplate
Original commit message from CVS:
- move the state_change signal emit to a better place, before changing
the parent state
- also call the parent state change handler in a bin
Original commit message from CVS:
- some pad.h reorg, better grouping of function
- added methods and default implementations to get supported formats,
seek methods/flags and query types.
- implemented pad activation/disabling
- start negotiation in the READY->PAUSED state
- added GST_PAD_IS_USABLE (better name?) to check if a pad can be used
for data transport (check if connected and peerpad is active)
- added query for segment end
Original commit message from CVS:
- added GstEventMask to specify event masks (next set of commits)
- use flags for seek methods (for use in masks)
- removed #if 0 from gstmemchunk.h
Original commit message from CVS:
- Documentation updates, renamed some _ methods because gtkdoc didn't
want to generate docs for them.
- Add some more events for future use.
Original commit message from CVS:
Make sizeof(GstBuffer) independent of config.h and HAVE_ATOMIC_H. This still
needs a more fundamental solution though.
Original commit message from CVS:
- Removed bufferpool code and move that to gstbuffer.c
- implemented refcounting on GstData
- implemented new buffer code based on Company's work in the EVENTS2 branch
- added boxed types for GstData/GstEvent/GstBuffer/GstBufferPool
- added refcounting to bufferpools and events
- use lockfree allocation for buffers
- simplified the clock, use lockfree allocation
- use GQueue in GstQueue for faster access to the tail element
- update core plugins to the new event API
Original commit message from CVS:
- Added a bunch of fast atomic operations on x86 with C fallbacks
- Added the code for refcounting in GstData
- Added a gstmemchunk allocator using atomic operations
Original commit message from CVS:
- Removed unused locking from the cothreads
- use G_*_DECLS in .h files
- remove gstlog.h include from gstobject.h, add to .c files
- removed unused refcounting code from gstobject
- small fixes in #includes
- Added Scheduling policy and priority properties to gstthread so that
SCHED_FIFO and SCHED_RR threads can be constructed.
Original commit message from CVS:
if you can't write to the registry (ie it is root-owned and you are user) and it
is out of date, just ignore it; plugin state will get written to the user reg
Original commit message from CVS:
more protective programming
cothread 0 cleans up higher cothreads if they're still around
use a magic number to protect against mem corruption in the struct
flames welcome
Original commit message from CVS:
ok, my latest added error checking and stuff
this reverts uraeus's patch but should tell us what goes wrong with munmap
Original commit message from CVS:
Fixes suggested by thomasvs to get rhythmbox working with basic threads
- int res;
+ int res = 0;
- res = munmap ((void *) thread, COTHREAD_STACKSIZE);
+/* res = munmap ((void *) thread, COTHREAD_STACKSIZE); */
Original commit message from CVS:
some debug info
remove the preventive munmap
reinstate the other munmap for cothread stocks which really should be there IMO
Original commit message from CVS:
ok, this seems to be the right fix for the basic scheduler.
I'd appreciate it if :
a) someone looks over these minimal changes and tells me if they're done
in the right way (especially the alignment argument ;))
b) others run lots of pipes with basic and tell me if they still have
issues
If all goes well I want to revert to the basic scheduler and do a release
Original commit message from CVS:
Don't seek past the end of the file
Fix a bug where the mapend was incorrectly calculated when we read past
the end of the file.
Original commit message from CVS:
Added a runtime option to use a dummy threading implementation that uses
NOPs for all synchronisation and threading operations.
Original commit message from CVS:
remove the "iterate_started" signal and replace it with pre_iterate and post_iterate callbacks.
Apps can now put a lock around an iterate so they can do stuff on the bin from another thread. much nicer than the signal approach.
Original commit message from CVS:
Whan the buffer is filled, the buffer is kept and added to the queue
when there is room again. Don't do this after a flush.
Original commit message from CVS:
put upstream events in an async queue and resend them at the start of the chain. not working as expected yet but a start
Original commit message from CVS:
Add an event function so that seek events are not forwarded when we
have a cache, seeking in the cache still needs to be implemented though..
Original commit message from CVS:
a couple of fixes here:
- forward eos events to all src pads, even if spider didn't connect them. this ensures that the pipeline will stay in a consistant state even when not all pads are sent data
- don't check for nonnull spider until it is actually needed. it really is null when it has been disposed and this method is called.
Original commit message from CVS:
added a "iterate_started" signal which fires before the iterate of a bin. useful for non-threadsafe operations like seek in threaded pipelines
Original commit message from CVS:
add an optional timeout for when queue blocks. when timeout is reached a GST_EVENT_FILLER is sent downstream
This is needed for gst-player since videosink has to be in the same thread as the ui, and spider blocks when there is no video (thus freezing the ui).
Original commit message from CVS:
only use ranked element factories for autoplugging. This is the only commit that needs to be backed out to reinstate previous behaviour.
Before your spider will work again, you will have to update/rebuild plugins and run gst-register.
Original commit message from CVS:
Created an overridable method for seeking on an element, along with a default
implementation.
make queue flush on discont (not entirely correct)
removed the new_media from the discont event.
Original commit message from CVS:
* fixups in the prop view/controller
* compilation fixes in the player
* add gst-editor to gst-all
* fixes to adder to comply with new osssink sync issues
* alsa fixes, although still 100% cpu is used, yum
* reenable locking of threaded elements, seems to work fine here
* fix a makefile in examples/plugins
Original commit message from CVS:
- The clock_wait now returns the difference between requested time and
unlock time.
- Misc defines like GST_SECOND in gstclock.h
- remove pre/post in gstelement.c until fixed.
- added release_locks to gstelement so that the element can unlock itself
- added some more predefined events.
- added folowing functions to gstpad:
- convert function: get the relation between formats on this pad
- query function: get stats about the pad (position/total/latency)
- internal connect function: find out how this pad connects to other
pad internally to the element.
- generic pad_dispatcher.
- removed the last bits of pullregion
- use release_locks on the queue.
- added some events to queue
- make gstthread use the new release_locks function
- make the scheduler use the new clock_wait functions
- added events to fakesink
- added query functions to filesrc
- swap type and offset in the bytestream seek API to match fseek
- added some event handling in bytestream.
Original commit message from CVS:
* implemented threadsafe property set/get system as discussed in
docs/random/wingo/threadsafe-properties
* some cleanups
* this change will cause binary incompatibilities, better rebuild them plugins
now, off to drink :-)
Original commit message from CVS:
* add gerror to gstplugin.c -- not fully propagated to periphery apis
* fix recursive dir creation in the xml registry
* comment identity props
* fix dependency resolution in lib loading
Original commit message from CVS:
* fix refcounting tests so that they compile and run, but they fail currently:
gst leaks obscene amounts of memory ;)
* fix plugin loading test so that it only refers to plugins within the gstreamer/
tree
* store gst plugin paths in the registry
* is GST_REGISTRY is set, only use the user registry with the PLUGIN_PATH explictly
specified by the user
* all tests should pass now except refcounting
Original commit message from CVS:
* added a get_perms_func to gstxmlregistry that will set _WRITABLE and _READABLE
as appropriate
* added an object property for location so that we can do some cleanup and initialization
Original commit message from CVS:
* GST_PLUGIN_PATH gets split into the user registry
* some debugging output in registry rebuilding
* don't go into =build, =inst, etc
* i really don't know what the current idiom is for the plugin test suites, disabling for now
still pending issues: what to do when other plugin paths are passed on the command
line for existing registries. if the existing registries were built against those
paths, the time checks work, but if not they will need to be rebuilt. i have a feeling
they should be rebuilt in any case, but it's a tricky issue.
Original commit message from CVS:
Check to see if the registry is out of date, and if so try to rebuild it.
WIERD THING: trying to run gst-register using system() fails. Apparently child processes
can't link to libs parent processes use? It's wierd, and it could be a libtool issue.
That's probably just as well, it would be better just to use -register's code from within
core and not rely on another binary.
Original commit message from CVS:
Totally rewritten registry handling.
- move the registry save/load code into a gstregistry subclass, this
will make it possible to use other registries (flat file, web based,
RDBMS type, etc..)
- a simple GMarkup xml registry is implemented
- use standard statically linked plugins for core elements.
- GstPlugin has a very well defined set of functions now
A little bytestream hack..
Added more info to -inspect.
Some more debugging info for clocking.
Small cleanups
I use ./gst-register --gst-plugin-path=/opt/src/sourceforge/gst-plugins/gst-libs:/opt/src/sourceforge/gst-plugins/
to register core and gst-plugins now.
Original commit message from CVS:
merged schedulers
- new file cothreads_compat.h to provide linking to desired cothreads package
- changes in basic and fast scheduler to use cothreads_compat.h
- updated Makefile to build the basic and the fast scheduler from both packages
- removed gststandardscheduler.c - it is not needed anymore
Available schedulers are now 'basic', 'standard', 'fastbasic' and 'faststandard' where the basic ones are built with old cothreads and the standard ones with the new cothreads.
Original commit message from CVS:
* gst_scheduler_factory_make () can accept NULL as the first arg now
* _create () sets the element sched and refcounts the scheduler
* corresponding touchups to gstpipeline and gstthread
Original commit message from CVS:
Header file fix (these ## are needed for multi-arguments) and a fix for gst_props_get() if safe = FALSE (we still need three arguments per fetch)
Original commit message from CVS:
let's not clobber our local variables -- i think this is a good short-term
fix until i get to hacking on the standard scheduler again.
Original commit message from CVS:
* a hack to work around intltool's brokenness
* a current check for mpeg2dec
* details->klass reorganizations
* an element browser that uses details->klass
* separated cdxa parse out from the avi directory
Original commit message from CVS:
- make all _get_list functions return a const reference to original lists and no copy
- redo code accordingly
- fix compile issue in dparam stuff
Original commit message from CVS:
Added --gst-fatal-warnings, the same as --g-fatal-warnings
It's named differently to avoid conflicting with --g-fatal-warnings, which is parsed
by gtk (which we don't depend on)
Original commit message from CVS:
registry handling changes
read up on it in docs/random/thomasvs/registry if interested
net effect should be transparent; ie. it will keep on working, but will
be more flexible than before. Testing with garnome seems to work now.
Should probably be rewritten completely, together with plugin loading, but
only after we spec it out ;) It's a bit messy.
Original commit message from CVS:
commit to make gstreamer follow the gtk function/macro naming conventions:
GstPadTemplate <-> gst_pad_template <-> GST_PAD_TEMPLATE
and the same for *factory and typefind.
Original commit message from CVS:
* new parser that uses flex and bison
- doesn't do dynamic pipelines yet...
* added GErrors to the gst_parse_launch[v] api
* added --gst-mask-help command line option
* fixed -o option for gst-launch
* GstElement api change:
- gst_element_get_pad
- gst_element_get_request_pad, gst_element_get_static_pad
- gst_element_get_compatible_pad
- gst_element_get_compatible_static_pad, gst_element_get_compatible_request_pad
- gst_element_[dis]connect -> gst_element_[dis]connect_pads
- gst_element_[dis]connect_elements -> gst_element_[dis]connect
* manual update
* example, tool, and doc updates for the api changes
- no more plugin docs in the core docs, plugins require a more
extensive doc system
Original commit message from CVS:
patch from jim thornton <jthornton@parc.com>:
Buffer flag symbols are enum values, so |'ing together doesn't do the right
thing, must use GST_BUFFER_FLAG_SET macro
Original commit message from CVS:
* form a semantic representation of the pipeline in preparation for
actual instantiation.
the parser is shaping up quite nicely; it should, in theory, be able to create
all types of pipelines that gstreamer supports
Original commit message from CVS:
add (incomplete) flex/bison-based parser to cvs
the tokenizer is functional, but the grammar definition is bad. this
probably breaks distcheck somehow, but hey.
Original commit message from CVS:
* add notify back to filesrc, it's needed for MVC applications
* remove notify printouts from gst-launch
* cleanup in gst-plugins configure.ac
* some jack updates
* remove SELF_ITERATING flag in favor of SEF_SCHEDULABLE (not a clear name,
but it's what we have for the moment)
* improve parsing of request pad names, no more sscanf
* fixes to the fastscheduler Makefile.am
Original commit message from CVS:
- Remove the propsprivate header file
- Added new API for properties.
- Moved the clock distribution to the scheduler.
- Removed the lock from GstCaps
- Added boxed types for Caps/Props
- Simplified the clock, new systemclock implementation
- Removed deprecated element_info/send_event functions
- First step at exposing more info in the pad_connect functions
- Queue cleanup
- Make the scheduler aware of other schedulers inside it
- Added the _SELF_SCHEDULABLE flag to gstthread
- Removed _get_widget from _utils, changed to new props API
- Make fakesink sync on timestamps when requested
- Removed the offset notify from filesrc
- Added a fast scheduler
- some scheduler cleanups.
Original commit message from CVS:
apply patch from jim thornton <jthornton@parc.com>:
"bugfix for intersecting int list with int range: the proper intersection
should be those ints in the list that lie within the range (rather than an
empty intersection)."
the reverse of this case doesn't exist, because if the entry1 is a list,
the members are broken out and tested seperately, therefore the intersection
would be int <-> int range, which does work.
Original commit message from CVS:
* added plugin_desc structures to libs, which makes their locations cached in the registry. this
speeds plugin loading considerably, especially on uninstalled versions.
* put the lib path before all others, for speed reasons.
* some fixes to adder's caps.
* added linefeeds (\n) to GST_DEBUG strings to match GST_INFO behavior. this is more sane. all
code will need to be converted. i think some perl can do this.
Original commit message from CVS:
s/POINTER/OBJECT/ in g_signal_new for NEW_PAD and PAD_REMOVED.
Very important for python bindings to know it's getting an GObject
vs a boxed anonymous pointer.
Original commit message from CVS:
* removal of //-style comments
* don't link plugins to core libs -- the versioning is done internally to the plugins with the plugin_info struct,
and symbol resolution is lazy, so we can always know if a plugin can be loaded by the plugin_info data. in theory.
Original commit message from CVS:
s/@GST_PLUGIN_LDFLAGS@/$(GST_PLUGIN_LDFLAGS)/
@-substitued variables variables are defined as make variables automagically,
and this gives the user the freedom to say make GST_PLUGIN_LDFLAGS=-myflag
Original commit message from CVS:
* s/gst_element_install_std_props/gst_element_class_install_std_props/ -- it just makes more sense that way
* added jack element, doesn't quite work right yet but i didn't want to lose the work -- it does build, register,
and attempt to run though
* imposed some restrictions on the naming of request pads to better allow for reverse parsing
* added '%s' to reverse parsing
* added new bin flag to indicate that it is self-iterating, and some lame code in gst-launch to test it out
* fixen on launch-gui
* added pkg-config stuff for the editor's libs
Original commit message from CVS:
added gst_util_set_value_from_string.
this could probably be refactored with gst_util_set_object_arg at a later date.
Original commit message from CVS:
* document gst_caps_debug
* change gst_caps_debug to accept a label argument, assists greatly
in debugging capsnego
* better names from gst_object_name_default
* some more debugging in gstpad.c
* require caps to match padtemplates on both side of a connection
* gstspider uses default naming so that names are globally unique
* moved filesrc offset arg to the top -- show up first in a prop list.
in the future we should have flags on props indicating which ones
it might be interesting for the end-user to change.
* initialize cothreads in the more standard way, and provide some more debugging
Original commit message from CVS:
make sure cothread->priv is NULL when uninited because we now check it
(added debugging line to gst_bin_remove while debugging)
Original commit message from CVS:
updated popt stuff:
- added 'gst_init_with_popt_table' to gst.h
- added a --silent option to launch to suppress g_object_notify events
Original commit message from CVS:
Store the element in the cothread private field.
If we remove the current entry in the cothread chain, make sure another
cothread is marked as COTHREAD_STOPPING.
Original commit message from CVS:
* add two apis:
* gst_element_connect_elements_many (elem1, elem2, ...)
- calls gst_element_connect_elements() in order
- should be called gst_element_connect_many, but we need to rename gst_element_connect_elements first
- simplifies common-case code
* gst_bin_add_many (bin, elem1, ...)
- calls gst_bin_add on all of the elems
- again, simplifying common code
Original commit message from CVS:
* warning fixes
* gst_object_set_name (name, NULL) uniquifies the name globally
- needs robusticizing
* gst_elementfactory_make can now take NULL as a second argument
Original commit message from CVS:
* a warning fix
* a potential commenting error fix
* more debug output when trying to set caps so I can actually tell from it
what's going on
Original commit message from CVS:
Fixed some warnings
Always recalculate caps intersection in perform_negotiate 'cause they
might have changed. (needs better solution probably)
Original commit message from CVS:
* changes to spider:
* add padtemplates so the connect functions can connect two request-pad
elements
* add a hack in gstelement.c. please look at this, Company, and see how
we can get around this
* add backwards caps-propagation support in identity, int2float, float2int,
adder, speed, volume
Original commit message from CVS:
* many fixes related to dynamic pipelines.
* addition of gst_element_disconnect_elements(), as per connect_elements()
* don't have a cow if typefind changes state in its signal handlers
* support of request pad -> request pad in connect_elements()
* some fixes in int2float that will eventually need to be ported to float2int and
adder
the gstelement api is getting bloated, expect a rewrite within the next month.
Original commit message from CVS:
appending caps to themself is not fatal, is it?
If it is, revert the patch, but please allow gst_caps_append (NULL, NULL);
Original commit message from CVS:
allow gst_init(NULL, NULL) to work
this fix was prompted by testsuite/test_gst_init.c, which thomasvs was running
on the autobuilder. they are good after all :)
Original commit message from CVS:
workaround for old popt versions, maybe this is the best way anyway (not alowing
for command line args that are not parsed with popt)
Original commit message from CVS:
to set default categories for an app, call set_categories before the gst_init
restores gst-register to its previous verbosity (but --gst-mask=0 works)
Original commit message from CVS:
first pass at integrating popt into gstreamer
note: you will need popt 1.6.3 or greater (configure checks for this) -- debian
people will either need to patch popt 1.6.2 or install 1.6.3 by hand.
Original commit message from CVS:
revert part of wingo's patch
wingo, I'm not doing this to piss you off ;)
but with your change we get the reverse issue : stuff in libs/gst needs
gstmarshal.[ch], which are only generated if we go in gst before libs.
So unless we just throw the egg at the chicken we'll have to settle for a
hack.
Alternatively, we could take the egg out of the chicken and put it in
a separate tarball which would then be installed ;)
Original commit message from CVS:
fix funny build issue by not linking plugin libraries to gstreamer core. this is
because they are plugins, not shared libraries per se, and will only be loaded by
the core itself. this change allows the core elements (schedulers, autopluggers, etc)
to use the core loadable libraries (bytestream, getbits, etc) as well as "ext" libs
like the new cothreads package.
Original commit message from CVS:
I don't think we wanted to change the include dir to gstreamer as well.
If we did, then we need major code cleanups all over so let's hold off for
a second.
Original commit message from CVS:
this is a really evil hack.
I would like for someone to help wingo and me fixing it properly ;)
and for that I could use a little basic education on some of the LD FLAGS
we need all over because trying to fix it properly got me confused.
Original commit message from CVS:
major rewrite of the spider.
Now uses GstSpiderConnection to track current connections and remember the way they're plugged.
Advantages of this approach:
- function prototypes are now much cleaner.
- Allow event propagation (EOS) to elements that are not connected but plugged.
- Allow deconstruction of plugged pipes. (not implemented)
Disadvantage:
- I screwed up naming (always get src and sink the wrong way). It's very inconsistent in the gstspider.[ch] files
- a little more time and memory are needed to manage the structs
Original commit message from CVS:
* removed cothread-specific code from gstinfo.c because the new cothreads has no cothread_self()
* added a new scheduler, untested but it does compile :-)
* cothreads links to the scheduler, not core now
* no installation of cothreads headers
Original commit message from CVS:
This patch (nearly) completes the removal of vertical events from the
core.
What it does:
- removal of the EVENT signal of GstElement (to be replaced by
g_object_notify)
- changing of the ERROR signal to allow recursive notification (like
deep_notify)
- implementing recursive notification with error events.
- removal of some functions in gstbin.c that are not used anymore.
- The function gst_element_info and gst_element_send_event now do
nothing but printing a warning, that these functions are gone. This is
done to allow plugins to catch up.
- Some bugfixes in XML saving are included, they simply were in the
file.
Original commit message from CVS:
initial checkin for the deep_notify signal which replaces INFO events in the long run.
PLEASE do not use gst_element_[info,message,error] anymore. Use g_object_notify instead.
Thank you.
Original commit message from CVS:
this fix makes sure that we actually request a pad from the template with
an unused name
this isn't optimal but gets the job done
should we move this code fragment to it's own helper function to use
everywhere stuff is requested according to a template ?
Original commit message from CVS:
- use autoplugging instead of predefined way on sometimes pads
- exchange plugtype with factories in the spider
- revamp the spider, now messier than before...
- bugfixing
- style corrections
Original commit message from CVS:
Added a first stab at a better clocking system.
It still needs more infrastructure for async notification and custom clock
implementors.
This thing can still deadlock the pipeline.
Original commit message from CVS:
some compile fixes, api changes, and i added the ability to create new chunks on the
stack, which can extend the main thread's stack up to 8M under linuxthreads. thanks
to billh for the {set,get}rlimit tip.
on the other hand, there's a nasty bug in cothreads when they are run without gthreads
that i'm still tracking down. that's the last bug though, at this point.
the commit is to syn the repository with my working copy before moving cothreads to a
separate module.
Original commit message from CVS:
Change soversion back to 0:0:0 and add use of -release flag for libtool.
This means that any program linking against libgst will automatically have
the specific release of libgst encoded into it. This enforces the fact
that (for the moment), the API/ABI is changing rapidly enough that you
can't link against 0.3.2 originally and have it still work with 0.3.3. It
might be possible, but highly unlikely.
When we get closer to a stable API/ABI, in the 0.5.0 timeframe most likely,
we will start using soversions as recommended in the libtool docs. Then
we have to pay more attention to forward and backwards compatiblity, or
rather, we have to *start* paying attention <g>
Original commit message from CVS:
fixed a number of bugs, added support for cothread-private data and
functions of the form void (*func) (int argc, void **argv)
the test app demonstrates the thread-safety of the cothreads lib
this is shaping up to be pretty solid.
Original commit message from CVS:
* a first pass at cleaning up the configure stuff
* new cothread library started, some experimental stack allocation code is in place
Original commit message from CVS:
should fix an error in a no-glib2 error message, an error in libxml stuff
(newer versions of libxml1 can be included as libxml/parser.h), and silencing
a warning in the cothreads stuff
Original commit message from CVS:
new, shiny hack uses mutexes to determine the current pthread_descr
without resorting to internal header files. muahaha ;)
this is only for linuxthreads, of course.
Original commit message from CVS:
added a test for pth and pthreads. in summary, it doesn't work because
in __pthread_find_self() some funny stack pointer math is done that
will result in no matches for __pthread_find_self(). this is dereferenced in
__errno_location, causing a segfault on context switch because of the errno-swapping
on the part of pth. it's a mess and i don't know how to get around it. i'll
have to look into what ngpt does for looking up errno, as it has kernel threads as
well as user threads.
Original commit message from CVS:
The core code from pth has been taken out and included in gstreamer.
This code is documented, more or less, in http://www-124.ibm.com/pthreads/docs/rse-pmt.ps.
This code is designed to replace cothreads.[ch], eventually.
Original commit message from CVS:
Delay pad negotiation until the element is in READY or higher. this will
gice the element a chance to open its devices before we start calling the
connect functions.
Make sure we use the real pad in the negotiation.
Some other small cleanups.
Original commit message from CVS:
miscellaneous fixes, added gst_pad_unset_sched() api.
although I unref the old pipeline and the cothread context gets freed in dynamic-pipeline.c,
I still get segfaults.
Original commit message from CVS:
* cleaning up duplicated code in gstbin.c
* added some sanity checks in gstpad.c
* added checks for failed connections in gstparse.c
* better docs in gstxml.c
Original commit message from CVS:
Previously filesrc would segfault when fed with the name of a directory.
Added check to ensure that the given file is a regular file.
Original commit message from CVS:
* fix doc build for glib2
* remove template files from cvs, they are generated with gtkdoc-mktmpl
* new, cleaner interface to the parser facilities
* cleanups in gstparse.c
Original commit message from CVS:
Landed the new improved capsnegotiation system.
The main idea is to keep track of the possible data types that can
pass through a connection. plugins can at any time inspect, adjust and
refine these caps. plugins also get notified when something changes to
the types so that they can reconfigure themselves.
Look at the updated plugins and the soon to be finished doc.
Original commit message from CVS:
* s/filter/plugin/
* add $(GST_LIBS) to all plugins
* move Makefile.am things around to a mostly standard layout
* remove HTTP flags/libs from elements since http element moved
Original commit message from CVS:
summary: fix xml in gstreamer
1) make clear distinction between loading xml that actually creates objects and loading xml that just
synchronizes properties with objects. moved most of gst_element_restore_thyself functionality to
gst_xml_make_element. this new function name can change if it sucks.
2) many various fixes. createxml and runxml work now.
3) doc updates.
4) GstSignalObject is stil broken. i have no idea what it's supposed to do.
Original commit message from CVS:
added function gst_xml_write_file() which writes a nicely formatted and indented
xml representation of an element to a file. you can use stdout or stderr, for
example.
Original commit message from CVS:
fixes for make distcheck
does GST_ELEMENT_IS_COTHREAD_STOPPING still exist ?
and if so, how should it be found by the bytestream test ?
Original commit message from CVS:
fixes to make distcheck work
changed registry out of date to warning to allow tests to continue regardless (any better suggestions much appreciated)
Original commit message from CVS:
Some small cleanups.
added a drop_probaility arg to identity, so it occasionally can drop buffers
to simulate network packet loss
Original commit message from CVS:
- Removed deprecated buffer flags.
- removed gst_element_signal_eos, replaced with gst_element_set_eos
to set the object to PAUSED, signal an eos event etc..
- small updates to documentation
- repair some plugins
Original commit message from CVS:
- Added a function to get the currently executing cothread
- Removed some useless includes
- _interrupt now returns a boolean so the behaviour after the interrupt
can be controlled by the scheduler.
- Added a better way to set/get the default scheduler.
- make thread and pipeline get the default scheduler.
Original commit message from CVS:
* save the plugin paths in the registry
* load them back
* don't look in PLUGIN_DIR ($prefix/lib/gst usually) when PLUGIN_BUILD_DIR
Original commit message from CVS:
Tee Fixes.
added cothread_stop (not used)
improved the pad event dispatcher.
added an event_received signal on the pad.
do less state changes in the autoplugger.
small scheduler fix.
Original commit message from CVS:
Better, cleaner state management of the scheduler by adding scheduler state
flags.
typefind has to interrupt instead of yield.
Fix a leak in the queue when it's dropping buffers.
Original commit message from CVS:
This is an attempt at not segfaulting on errors but reporting some
usefull info instead.
- bin changes so errors can propagate.
- changed the _FAST macros to _CAST because that is what they do.
- removed all references to cothreads out of the core, they are
really a scheduler issue, handler with a sched_private gpointer.
- added a live buffer count, for debugging buffer leaks.
- added error checking in gst_scheduler_state_transition this solves the
"out of cothreads" problem.
- GST_ELEMENT_NO_ENTRY == GST_ELEMENT_INFINITE_LOOP
- added 2 private element flasg for use by the scheduler
(_COTHREAD_STOPPING) is now
- added scheduler entry points:
- _yield : to create possible scheduling points.
- _interrupt: to stop execution of an element.
- _error: to signal en error condition to the scheduler.
- improved error messages for pads.
- signal gst_element_error where appropriate.
- added the a new bin to the parent before entering it so one can reference
its children.
- queue memleak fixes on dispose.
- added possible deadlock detection in queue (turned off be default)
- GstBasicScheduler is a real class of its own now, hiding its internal
variables.
- GST_ELEMENT_IS_COTHREAD_STOPPING is gone. either call explicit _yield
operations, or make a sane loop.
- Better state change handling in filesrc. Better error reporting/recovery
too.
- updated core plugins.
- detect non decoupled elements on scheduler boundries and error.
Original commit message from CVS:
- Reclaim cothread state even if the cothread was never activated after
the free.
- fix the bin state change when there are no more children.
- use a real method to signal the parent bin of a state change.
- move the state change policy in the scheduler.
- remove the unused and ridiculous state change event
- don't free the cothread state when the element is disabled. only free it
when the element is removed from the scheduler.
Original commit message from CVS:
cothread cleanup.
- removed some old code.
- ran the thing through indent
- rename cothread_init/free to cothread_context_init/free
- implement cothread_free/destroy to clear the cothread_state slot
- make cothread_init reuse empty slots.
minor cleanups in error reporting (gstpad, gstelement)
code cleanup in gstthread
make unexpected state changes in gstthread less fatal
free the cothread_state in the scheduler.
This one passes all the current cvs testcases including dynamic-pipeline.
Original commit message from CVS:
Some more work on cleanup.
- added two functions in the scheduler _setup and _reset to initialize
the context. In the case of the cothread context we have to map the
cothread stack space onto the threads stack.
- setup/reset the scheduler context in the threads context.
- fix the ghostpad cleanup.
- slightly changed the scheduler code to cleanly remove connections.
Original commit message from CVS:
- Elements can now send events to their parent.
- remove the g_signals from the core for parent<->child communication
- the application can easily get element info by listening for an event
signal from the toplevel bin.
- added gst_element_info()/_error().
- fakesrc and fakesink use the info event instead of g_print.
- GST_TYPE_* causes segfaults with elect fence, rever to G_TYPE_POINTER
until we know what's wrong.
- various leaks fixed wrt element destroy.
- The object that created the event is now stored as GST_EVENT_SRC
