Check for metadata writability when setting caps on buffer or when copying
metadata flags. Only enable these extra assertions in git versions.
This should help us find bad elements.
Original commit message from CVS:
* gst/gstbuffer.c: (gst_buffer_finalize):
Avoid costly typechecking for trivially correct pointers.
* gst/gstpoll.c: (gst_poll_wait):
Add some G_LIKELY here and there.
* libs/gst/base/gstadapter.c: (gst_adapter_push):

2008-10-06 Andy Wingo <wingo@pobox.com>
* gst/gstbuffer.h (GST_BUFFER_FREE_FUNC): New API, a free function
that will be called on the malloc_data to free it. Basically a way
to avoid subclassing when all you need is a different free
function, i.e. free() instead of g_free().
* gst/gstbuffer.c (gst_buffer_finalize): Free malloc_data via
calling the free function.
(gst_buffer_init): Initialize the free function to g_free.
Original commit message from CVS:
* gst/gstbuffer.c:
Update some comments.
* tools/gst-inspect.c: (print_element_properties_info):
Improve printing of flags.
Original commit message from CVS:
* gst/gstbuffer.c: (gst_buffer_finalize):
Make it once again possible to free GstBuffers in the default
build.
The poisoning scribbles on parts of the miniobject we need in
order to free it.
Fixes#480341
Original commit message from CVS:
* gst/gstbuffer.c: (gst_buffer_finalize):
Implement poisoning for GstBuffer if --enable-poisoning is specified.
When finalizing a buffer the complete struct is filled with 0xff,
thus making a use of the buffer after the final unref impossible.

Original commit message from CVS:
* gst/gstbuffer.c: (gst_buffer_make_metadata_writable),
(gst_buffer_create_sub):
Copy duration/offset_end/caps when creating a subbuffer of the
complete parent.
Make the subbuffer read-only when we make the metadata writable for
now. Fixes#351768.
* tests/check/gst/gstbuffer.c: (GST_START_TEST):
Added check for metadata copy when creating subbuffers.

* gst/gsttask.c: (gst_task_join):
Small doc updates.
* gst/gstpad.c: (gst_pad_activate_pull), (gst_pad_activate_push),
(gst_pad_stop_task):
When pad (de)activation failed for some reason, restore the old
activation mode and set the pad to flushing instead of assuming the
pad is deactivated.
If the _task_join() failed, reinstall the task on the pad so that it can
be stopped later and return an error.
Original commit message from CVS:
* gst/gstbuffer.c: (gst_buffer_get_type), (gst_buffer_new),
(gst_subbuffer_get_type), (gst_buffer_create_sub):
Avoid function call for known types by keeping the buffer and
subbuffer GType global.
* plugins/elements/gstfilesrc.c: (gst_file_src_create_read):
Random silly optimisations in read() path.
Original commit message from CVS:
* gst/gstbuffer.c: (_gst_buffer_copy), (gst_buffer_create_sub):
* tests/check/gst/gstbuffer.c: (GST_START_TEST),
(gst_buffer_suite):
No point in checking if the size of the subbuffer > 0, the
code handles it correclty as demonstrated by unit test.
Also add a unit test for the zero sized _new_and_alloc and
_copy. Fixes#346663.

(gst_buffer_is_span_fast), (gst_buffer_span):
Init _type for consistency.
Use _FLAGS macro to avoid type check.
Avoid unneeded type checks in subbufer code.
Original commit message from CVS:
* gst/gstbuffer.c: (_gst_buffer_initialize):
Register subbufer along with the buffer type so that
it does not accidentally gets registered from N
different streaming threads in a non threadsafe way.
Original commit message from CVS:
* gst/gstbuffer.c: (gst_buffer_make_metadata_writable):
gst_buffer_make_metadata_writable() should maintain the
buffer flags (those that make sense at least) (see #340859).

Original commit message from CVS:
* gst/gstbuffer.c: (gst_buffer_span):
gst_buffer_span should copy the timestamp of the first buffer
if they were both originally overlapping subbuffers of the
same parent, using the same logic as the 'slow copy' case.

Update docs, source pads should call the peer linkfunction
so they can atomically perform the pad link.
Original commit message from CVS:
* gst/gstbuffer.c: (gst_subbuffer_init):
Set READONLY flag on subbuffers, so that gst_buffer_make_writable()
works correctly in all circumstances (we could have just copied
the parent buffer's readonly flag, but conceptually it seems
cleaner to mark all subbuffers as read-only). (based on patch
by Alessandro Decina, #314710).

(test_make_writable), (test_subbuffer_make_writable),
