Other gstreamer repositories have their own valgrind suppression file
directly in the repository.
Add a suppression file to the core gstreamer repository too, this makes
it easier to use it with gst-build which does not check out the common
module.
This is also a little step towards the removal of the common submodule.
NOTE: the added file is the latest version from the "common" repository
but it has been renamed from gst.supp to gstreamer.supp for symmetry
with the suppression files in the other repositories.
Since elements_fdsrc.test_num_buffers uses blocking pipe on Windows,
the test will never be finished. But emulating non-blocking fd without
win32 APIs on Windows is a little tricky.
For metas where order might be significant if multiple metas are
attached to the same buffer, so store a sequence number with the
meta when adding it to the buffer. This allows users of the meta
to make sure metas are processed in the right order.
We need a 64-bit integer for the sequence number here in the API,
a 32-bit one might overflow too easily with high packet/buffer
rates. We could do it rtp-seqnum style of course, but that's a
bit of a pain.
We could also make it so that gst_buffer_add_meta() just keeps metas in
order or rely on the order we add the metas in, but that seems too
fragile overall, when buffers (incl. metas) get merged or split.
Also add a compare function for easier sorting.
We store the seqnum in the MetaItem struct here and not in the
GstMeta struct since there's no padding in the GstMeta struct.
We could add a private struct to GstMeta before the start of
GstMeta, but that's what MetaItem effectively is implementation-
wise. We can still change this later if we want, since it's all
private.
Fixes#262
gstharness.c: Use G_GSIZE_FORMAT instead of hard-coding %zu
error: unknown conversion type character 'z' in format [-Werror=format]
gst-inspect.c: GPid is void* on non-UNIX, and we only use it on UNIX
error: initialization makes pointer from integer without a cast [-Werror]
gstmeta.c: Use and then discard value
error: value computed is not used [-Werror=unused-value]
With this, gstreamer builds with -Werror on MinGW
While extremelly rare, time and gst_date_time_new_* will have
diff values and potentially trigger an assertion. Thus move
the calls as closely together as possible to mitigate this.
We have to ensure that all background threads from thread pools are shut
down, or otherwise they might not have had a chance yet to drop their
last reference to the pipeline and then the assertion for a reference
count of 1 on the pipeline fails.
Otherwise it can easily happen that the pad is destroyed before the
thread disappears, as happened sometimes in the test_pad_probe_block_add_remove
test where joining of the thread was done *after* the pad was unreffed
and destroyed.

Existing test for iterating/removing buffer meta data was insufficient
to detect linked list corruption when removing multiple items, and could
also suffer from such corruption in attempting to count remaining items.
Modified the one test and added several others to exercise multiple
scenarios.
Validates fix for issue #332.
We won't be able to do ASSERT_CRITICAL, but the main body of the tests
are still valid, and given we ship GStreamer with this configuration, it
is important to be able to run some tests against it.
Allows determining from downstream what the expected bitrate of a stream
may be which is useful in queue2 for setting time based limits when
upstream does not provide timing information.

A pointer to a hook in this list can easily not be unique, given both
the slice-allocator reusing memory, and the OS re-using freed blocks
in malloc.
By doing many repeated add and remove of probes, this becomes very easily
reproduced.
Instead use hook_id, which *is* unique for a added GHook.
If a segment has stop == -1, then gst_segment_to_running_time()
would refuse to calculate a running time for negative rates,
but gst_segment_do_seek() allows this scenario and uses a
valid duration for calculations.
Make the 2 functions consistent by using any configured duration
to calculate a running time too in that case.

Using a rate of 1.1 in the test is causing the test to
fail on 32-bit because ceil(1.1 * 10) can round to 12.
Instead use a rate 2.0 that can be expressed as floating
point number and doesn't trigger the problem.

Fixes for gst_segment_position_from_running_time_full() when
converting running_times that precede the segment start (or
stop in a negative rate segment)
The return value was incorrectly negated in those cases.
Add some more unit test checks for those cases, and especially
for segments with offsets.
Otherwise it's not guaranteed that buffers are actually on disk after
pushing them, and reading the file via g_file_get_contents() might not
include them yet.
This reverts commit 11e0f451eb.
When pushing a sticky event out of a pad with a pad probe or pad offset,
those should not be applied to the event that is actually stored in the
event but only in the event sent downstream. The pad probe and pad
offsets are conceptually *after* the pad, added by external code and
should not affect any internal state of pads/elements.
Also storing the modified event has the side-effect that a re-sent event
would arrive with any previous modifications done by the same pad probe
again inside that pad probe, and it would have to check if its
modifications are already applied or not.
For sink pads and generally for events arriving in a pad, some further
changes are still needed and those are tracked in
https://bugzilla.gnome.org/show_bug.cgi?id=765049
In addition, the commit also had a refcounting problem with events,
causing already destroyed events to be stored inside pads.
Previously gst_buffer_list_foreach() could modify (drop or replace)
buffers in non-writable lists, which could cause all kinds of problems
if other code also has a reference to the list and assumes that it stays
the same.

gst_buffer_list_new_sized(0) will cause an underflow in a calculation
which then makes it try to allocate huge amounts of memory, which
may lead to aborts.

In the case where the user sets a new padprobeinfo->data in a probe
where the data is a sticky event, the new sticky event should be automatically
sticked on the probed pad.

Remove unneeded reapplication of patterns. Besides being
superfluous (gst_debug_reset_threshold already applies
patterns) it was also wrong and didn't stop checking patterns
after the first match (broken in 67e9d139).
Also fix up unit test which checked for the wrong order.

The queue gets filled by the tail, so a query will always be the tail
object, not the head object. Also add a _peek_tail_struct() method to the
GstQueueArray to enable looking at the tail.
With unit test to prevent future regression.

Position queries with GST_FORMAT_TIME are supposed to return stream
time.
gst_base_sink_get_position() estimates the current stream time on its
own instead of using gst_segment_to_stream_time(), but the algorithm
used was not taking segment.offset into account, resulting in invalid
values when this field was set to a non-zero value.
https://bugzilla.gnome.org/show_bug.cgi?id=792434
Occasionally this test would fail, especially if the system is under load,
because the position query would pick up the last position from the
last buffer timestamp which has a lower timestamp than what we're
looking for. The sleep is long enough, however. It's unclear to me why
exactly this happens but there seems to be some kind of scheduling
issue going on as the streaming thread floods the sink with buffers.
Let's throttle the fakesrc to 100 buffers per second and make the sink
sync to the clock to restore some sanity. It should be totally sufficient
to test what we want to test, and seems to make things reliable here.
Set up all ten pipelines and preroll them first, and only set
them to playing to run wild after they're all set up. If we set
them to PLAYING directly and let those threads run wild, then
it might take ages (many seconds) for the other pipelines to
even get up and running, especially on machines with only one
or two cores, and operating systems that suck at scheduling.
Now the fakesink test takes 19 secs instead of 71 secs on a
single-cpu windows machine.
Scale the number of threads used in the stress tests according to
the number of cores/cpus. We want some contention, but we also
don't want too much contention, as some operating systems are
better at handling 100 threads running wild on a single core
than others.
Add header with structure sizes for 64-bit windows as well.
They're almost the same as on Linux, but it looks like things
like padding unions get aligned slightly differently so there
are a handful of differences:
sizeof(GstGhostPad) is 528, expected 536
sizeof(GstPad) is 512, expected 520
sizeof(GstPadProbeInfo) is 64, expected 72
sizeof(GstProxyPad) is 520, expected 528
The test checks that categories not covered by the pattern in the
GST_DEBUG string have debug level GST_LEVEL_DEFAULT set, but previous
tests mess with the default threshold, which made this test fail on
Windows or when run with CK_FORK=no. Fix this by resetting everything
at the beginning, and then also do a sanity check afterwards.
Add a gst_base_src_submit_buffer_list() function that allows subclasses
to produce a bufferlist containing multiple buffers in the ::create()
function. The buffers in the buffer list will then also be pushed out
in one go as a GstBufferList. This can reduce push overhead
significantly for sources with packetised inputs (such as udpsrc)
in high-throughput scenarios.
The _submit_buffer_list() approach was chosen because it is fairly
straight-forward, backwards-compatible, bindings-friendly (as opposed
to e.g. making the create function return a mini object instead),
and it allows the subclass maximum control: the subclass can decide
dynamically at runtime whether to return a list or a single buffer
(which would be messier if we added a create_list virtual method).

Convenience function to just grab all pending data
from the harness, e.g. if we just want to check if
it matches what we expect and we don't care about
the chunking or buffer metadata.

Remove gst_init() from a few tests. Use _OBJECT variants in logging. Remove
arbitrary extra blank lines. Make push_event() more like push_buffer() - set
the event to NULL and add cleanup to _chain_data_clear().
Using two (or more) probes on the same pad where one of the probe
returns HANDLED or DROP is tricky since the other probes might
not be called.
Instead use regular probes and a proper pad (the sinkpad already existed,
it only required to be activated and have a dummy chain function for
the events/buffers to be received/handled properly)
Failure by this commit 2dfa548f36, which is
to append hooks instead of prepend.
Because of this change, aggretated_cb is not called and leads to failure.

When this is TRUE, we really have to produce output. This happens
in live mixing mode when we have to output something for the current
time, no matter if we have enough input or not.
When registering categories after gst_init() we would re-check *all*
categories against the existing GST_DEBUG patterns again, whereas
it's enough to just check the new category. Moreover, we would parse
the GST_DEBUG pattern string again and re-add that to the existing
pattern list for every newly-registered debug category, and then
check that against all categories of course. This made registering
categories after gst_init() very very slow.
