* gst/elements/gstidentity.c: (gst_identity_class_init): GstBuffer is
a boxed type, marshal the signal with VOID__BOXED, not VOID__POINTER
Original commit message from CVS:
* gst/schedulers/gstoptimalscheduler.c: (add_to_group),
(gst_opt_scheduler_iterate):
Aplied patch #154061. Running a pipeline in which an element
calls GST_ELEMENT_ERROR in the chain function, the opt
scheduler doesn't unref the chain so it never gets freed.
Original commit message from CVS:
* gst/gststructure.c: (gst_structure_get_abbrs),
(gst_structure_from_abbr), (gst_structure_to_abbr):
Remove that ugly if-then thing in the code that converts
between strings and types.
Original commit message from CVS:
* gst/gstscheduler.c: (gst_scheduler_add_element),

Original commit message from CVS:
* gst/parse/parse.l:
* testsuite/parse/parse1.c: (main):
Since parse can do 'element name=a:b' make 'a:b.' work as
well.
Added testcase to verify fix.
Original commit message from CVS:

Set element to EOS before sending EOS event
Original commit message from CVS:
* gst/elements/gsttypefindelement.c:
(gst_type_find_element_handle_event):
Handle EOS events when doing the transition from
typefind to data passing. This should fix the
infinite loops in short files.
Original commit message from CVS:
* gst/gstthread.c: (gst_thread_change_state),
(gst_thread_child_state_change):
Make sure no iteration happens while performing
the state change as it could mess up the internal
consistency of the thread state.
Original commit message from CVS:
* gst/gstthread.c: (gst_thread_dispose), (gst_thread_sync),
(gst_thread_change_state), (gst_thread_child_state_change):
Do not try to grab the iterate lock in the state change method
when we are in the same thread as the iterate or else we
could deadlock. Some other cleanups.
Original commit message from CVS:
* gst/elements/gsttypefindelement.c: (stop_typefinding):
Push the buffer store instead of clearing it in case that
the stream is not seekable.
Original commit message from CVS:
* gst/gstthread.c: (gst_thread_init), (gst_thread_change_state),
(gst_thread_main_loop):
Lock the iteration and the state change so that automatic
negotiation and fixation does not happen at the same time
as the in stream negotiation.
Original commit message from CVS:
* gst/gstelement.c: (gst_element_change_state):
Well, actually, I was about to remove this insane assert when
I noticed Wim already did that. A warning is nice so we can
fix actual ugs (using --g-fatal-warnings and backtraces), so
I added that instead.

* gst/registries/gstxmlregistry.c (gst_xml_registry_open_func):
Don't use O_EXCL to open temporary registry. It will prevent

set the factory in the class struct, so gst_element_get_factory
actually works
* gst/parse/grammar.y:
set element to playing when it gets unlocked as we can't rely on the
bin state - all elements in the bin state might still be locked in
NULL)

(gst_bin_child_state_change_func), (set_kid_state_func),
(gst_bin_set_state), (gst_bin_change_state_norecurse):
make state changes work correctly and reentrant (so removing
elements from bins during state changes of bins doesn't cause
segfaults or even wrong states)
add debugging category and debugging output to print children states
* gst/gstbin.c: (gst_bin_dispose):
add some assertion checks
* gst/gstbin.h:
* gst/gstbin.c: (gst_bin_sync_children_state):
deprecate this function - it just does gst_bin_set_state (bin,
GST_STATE (bin))
* testsuite/threads/queue.c: (main):
don't use gst_bin_sync_children_state anymore
* testsuite/states/Makefile.am:

some adjustments to change states correctly, too
* gst/gstthread.c: (gst_thread_change_state):
don't enable/disable "threadsafe" properties, they're unused and
cause random segfaults

the queue check randomly passes now, ignore it
Original commit message from CVS:
* gst/schedulers/entryscheduler.c:
(gst_entry_scheduler_loop_wrapper),
(gst_entry_scheduler_chain_wrapper),
(gst_entry_scheduler_get_wrapper):
reset the state when the cothread starts, so we don't get assertion
failures on restarting of cothreads
Original commit message from CVS:
put symbols in the sections.txt into the right sections (so that we dont get wrong undocumented symbols)
added TITLE tags where they were missing
fixed section names so that gtk-doc introspection works
fixed typos in api docs and docbook docs
added some thoughts about new interfaces (to personal notes)
Original commit message from CVS:
* gst/gstelement.c: (gst_element_link_pads_filtered):
use correct sinkpad, if only sinkpad is specified, but not srcpad
(fixes#147889)
* gst/gstelement.c: (gst_element_set_state_func),
(gst_element_change_state): ref/unref the element, signal handlers
could get rid of the element otherwise

(group_dec_link), (gst_opt_scheduler_pad_link),
(group_inc_links_for_element), (group_migrate_connected):
Call group_inc_link with the proper src->sink ordering --
break this, and we break sort_chain. patch from wingo for bug
147713.
Partially revert patch 1.89. When adding a loop based element to
the scheduler, the links to other groups are automatically followed
and incremented. This should not happen because the bin will call
pad_link explicitly for those connection, resulting in them counted
twice. Results in assertion failure on pipeline cleanup.
Original commit message from CVS:
* gst/gstvalue.c: (gst_greatest_common_divisor):
use ints and return ints, fractions only use ints, too, so this
avoids accidently casting multiplications to unsigned
(gst_value_lcopy_fraction): it's ints, not uint32
(gst_value_set_fraction): disallow minint, multiplying and negation
are broken with it
(gst_value_fraction_multiply): fix to make large numbers work and get
rid of the assumption that the multiplication of two ints fits an
int64 - dunno if that's true for all systems
* testsuite/caps/Makefile.am:

strings.

GError's are boxed, not objects
* gst/gstmarshal.list:

Original commit message from CVS:
2004-07-14 Andy Wingo <wingo@pobox.com>
* gst/gsttag.c: Add a tag merge func for pointers. The header was
there all along, but the function wasn't. (guile-gstreamer's build
system uses the address of the function -- I wasn't actually
trying to use this.)
2004-07-13 Andy Wingo <wingo@pobox.com>
* gst/gstpad.c (gst_pad_try_set_caps): Naive link functions (such
as gst_pad_proxy_pad_link) just link to every other pad when they
are called. In the case where the graph has cycles, this will mean
that a call to try_set_caps will recurse. Allow this recursion
and return OK, while we wait for the first try_set_caps to give a
proper return value.
(gst_pad_link_call_link_functions): Since this function is the
only one to set the NEGOTIATING flag on a pad, if the flag is set
it means that the link functions have indirectly recursed. If this
happens, error out to avoid infinite recursion and an eventual
SEGV.
(gst_real_pad_class_init): Remove a crufty GtkObject comment.
(gst_pad_proxy_getcaps): Intersect the result with the template
caps to ensure that the return value is valid.
2004-07-11 Andy Wingo <wingo@pobox.com>
* gst/gstdata.c (gst_data_is_writable): s/>=/>/. If there is only
one refcount, the calling function is the owner of the buffer.
Original commit message from CVS:

is already migrated.
Original commit message from CVS:
* gst/schedulers/gstoptimalscheduler.c: (group_dec_link),
(gst_opt_scheduler_pad_link), (group_migrate_connected):

end up in a group. This fixes the testsuite again.

correctly. Fixes#144510.

Original commit message from CVS:

Original commit message from CVS:
* gst/gstelement.c: (gst_element_class_init),
(gst_element_set_state), (gst_element_set_state_func):

struct that was already added in 0.7 for this.
* gst/gstbin.c: (gst_bin_foreach), (set_kid_state_func),
(gst_bin_change_state):
make gst_bin_foreach works similar to other foreach functions, plug
memleaks in it. Make functions using it work with the new approach.
Document gst_bin_foreach, so it can be exported if we want to
* gst/gstbin.c: (gst_bin_class_init), (gst_bin_set_state):

* gst/gstbin.c (gst_bin_add_func): If we're adding an element
whose state is higher than the bin state, raise the bin state to
ensure that bin state := highest child state.
Original commit message from CVS:
2004-07-11 Andy Wingo <wingo@pobox.com>
* gst/gstbin.c (gst_bin_foreach): New static function. Calls a
procedure on the children of a bin. Assumes that the procedure can
change the set of children.
(set_kid_state_func): New static function.
(gst_bin_change_state): Use gst_bin_foreach to call
set_kid_state_func. Fixes a bug: if a child had a state-change
handler that removes it from the bin, there would be a segfault.
Hopefully it should also work in the case where the state-change
handler on one child adds or removes other children. In any case,
fixes should go to gst_bin_foreach.

* gst/gstbin.c: (gst_bin_remove), (gst_bin_dispose):
* gst/gstthread.c: (gst_thread_dispose), (gst_thread_catch),
(gst_thread_main_loop):
Since remove is virtual in GstBin we must not assume the
elements GList to have anothing usefull.
Add some more logging to GstThread and be a bit more paranoid
when resetting the scheduler.
Set the state of the bin to NULL before removing the children.

* gst/gstpad.c: (gst_pad_check_schedulers),
(gst_pad_can_link_filtered), (gst_pad_link_filtered),
(gst_pad_link_prepare):
check that pads that get linked belong to the same manager. The old
code allowed linking elements before putting them into bins, so it
worked to link them and then put them in different threads, which
lead to weird behaviour.
Since this effectively disallows linking elements before putting
them in a bin, some applications might not work after this and error
out. If these applications are too critical, we might need to revert
that patch. Please test this before the next release...
