8970bda4ba gst/gstquery.h
Original commit message from CVS:
2005-05-06  Andy Wingo  <wingo@pobox.com>

* gst/gstquery.h
* gst/gstquery.c (_gst_query_initialize): Extend GstQuery from
GstData, init a memchunk.
(standard_definitions): Add a few query types, deprecate a few.
(gst_query_get_type): New proc.
(_gst_query_copy, _gst_query_free, gst_query_new): GstData
implementation.
(gst_query_new_application, gst_query_get_structure): New public
procs.

* docs/design/draft-query.txt: Removed LINKS from the query types,
because all the rest can be dispatched to other pads -- seemed
ugly to have a query that couldn't be dispatched. internal_links
is fine as a pad method.

* gst/gstpad.h: Add query2 as a pad method, add the new functions
in gstpad.c, but maintain binary compatibility for the moment.
Will fix before 0.9 is out.

* gst/gstqueryutils.c:
* gst/gstqueryutils.h: New files, implement 3 methods for each
query type: parse_query, parse_response, and set. Probably need an
allocator as well.

* gst/gst.h: Add gstquery.h and gstqueryutils.h to the list.

* gst/elements/gstfilesink.c (gst_filesink_query2):
* gst/base/gstbasesrc.c (gst_basesrc_query2): Replace old query,
query_types, and formats methods.

* gst/gstpad.c (gst_pad_query2, gst_pad_query2_default)
(gst_pad_set_query2_function): New functions.
(gst_real_pad_init): Set query2_default as the default query2
function. Basically just dispatches to internally linked pads.

Needs review!

* gst/gstdata_private.h (_GST_DATA_INIT): Set data->refcount to 1
without using the atomic operations. Only one thread can possibly
be accessing the data at this point. Changed so as to avoid
gst_atomic operations.

65dd8e9726 gst/gstpad.c: Remove handling of filtered caps. Fix/merge functions that handle filtered links.
Original commit message from CVS:
* gst/gstpad.c: Remove handling of filtered caps.  Fix/merge
functions that handle filtered links.
* gst/gstpad.h: Remove 'appfilter' field and prototypes of
removed functions.
* gst/gstutils.c: Fix/remove utility functions that handle
filtered caps.
* gst/gstutils.h:
* gst/gstvalue.c: Add serialization/deserialization of caps
* gst/parse/grammar.y: Ignore filtered caps when linking.  This
requires fixing so that the filter caps notation creates
a capsfilter element and sets the filter_caps property.  I
think everyone probably wants to keep the shorthand notation.
* docs/gst/tmpl/gstelement.sgml: updates for API changes.
* docs/gst/tmpl/gstpad.sgml:
* gst/elements/gstelements.c: Register capsfilter element.
* gst/Makefile.am: fix spacing

* testsuite/threads/threadi.c: (cb_timeout), (cb_quit), (cb_eos),
(cb_state), (cb_play), (main):
Fix non-recursive state changes to *really* change the state
of the object, and not just call parent_class->state_change.
Fix a lot of lockups caused by this. Fixes #132775. Add test
for the problem. Also enable test to show #142588 (fixed).
* gst/gstthread.c: (gst_thread_change_state),
(gst_thread_child_state_change):
Don't exit the thread if we go to NULL and are inside thread
context. Instead, return control to the main thread context
and exit from there.
* gst/gstelement.c: (gst_element_disable_threadsafe_properties):
Don't unset virtual functions, since those may still be used.
That's not necessarily correct, but suffices for now.

(gst_test_sink_chain), (gst_test_sink_loop), (gst_test_sink_init),
(cb_error), (main):
Add tests to show #150546. Pass, but should fail (currently
disabled from the testsuite).
* gst/gstscheduler.c: (gst_scheduler_dispose):
Dereference child schedulers on dispose (#94464).
* testsuite/bytestream/filepadsink.c: (gst_fp_sink_init):
Fix typo.
* testsuite/threads/thread.c: (main):
