31383e4413 gstpad: Avoid stream-dead-lock on deactivation
The following case can happen when two thread try to activate and
deactivate a pad at the same time:
T1: starts to deactivate, calls pre_activate(), sets in_activation
    to TRUE and carries on
T2: starts to activate, calls pre_activate(), in_activation is TRUE
    so it waits on the GCond
T1: calls post_activate(), tries to acquire the streaming lock ..
    but can't because T2 is currently holding it

With this patch, the deadlock will no longer happen but does not
solve the problem that:
T2: will resume activation of the pad, set the pad mode to the target
   one (PUSH or PULL) and eventually the streaming lock gets released.
T1: is able to finish calling post_activate() ... but ... the pad
   wasn't deactivated (T2 was the last one to "activate" the pad.

this seems to give much better granularity on Windows
systems, where before this change there would often be
10-20 lines of debug log with the same timestamp up front.

5feff26624 plugin: plugin_load() must return a ref even if it was loaded already
Fix refcounting issue when plugin was loaded already.
gst_plugin_load() is supposed to return a ref, so it
must always return a ref.

This also fixes the gstplugin unit test on windows where
fork is not available and where test_load_coreelements()
would unref a plugin ref it didn't get and then mess up
the internal registry plugin list state for the next test,
in case where the test registry does not exist yet.

67e9d13950 info: fix performance issue with registering categories after gst_init()
When registering a new debug category after gst_init(), simply check
the existing patterns against that new category.

No need to iterate over all categories and recheck them all against
the existing patterns.

Also, no need to re-parse the existing pattern string set via GST_DEBUG
and add the same set of match patterns all over again to the existing
list of match patterns every time we register a new debug category.

Combined with iterating all debug categories on a change this would
make adding debug categories after gst_init() very very very slow.

512cec3dea pad: gst_pad_activate_mode() always succeed if same mode
Checking that the pad is in the correct mode before the parent is
checked makes the call always succeed if the mode is ok.

This fixes a race with ghostpad where gst_pad_activate_mode() could
trigger a g_critical() if the ghostpad is unparented while the
proxypad is deactivating, for instance if the ghostpad is released.
More specifically, gst_ghost_pad_internal_activate_push_default()'s
call to gst_pad_activate_mode() would fail if ghostpad doesn't have a
parent. With this patch it will return true of mode is already
correct.

d915dd4b20 gstpad: Make pad (de)activation atomic
The following could happen previously:
* T1: calls gst_pad_set_active()
* T2: currently (de)activating it
* T1: gst_pad_set_active() returns, caller assumes that the pad has
  completed the requested (de)activation ... whereas it is not
  the case since the actual (de)activation in T2 might still be
  going on.

To ensure atomicity of pad (de)activation, we use a internal
variable (and cond) to ensure only one thread at a time goes through
the actual (de)activation block

d106390adc element: add gst_element_foreach_*pad()
Add convenience API that iterates over all pads, sink pads or
source pads and makes sure that the foreach function is called
exactly once for each pad.

This is a KISS implementation. It doesn't use GstIterator and
doesn't try to do clever things like resync if pads are added
or removed while the function is executing. We can still do that
in future if we think it's needed, but in practice it will
likely make absolutely no difference whatsoever, since these
things will have to be handled properly elsewhere by the element
anyway if they're important.

After all, it's always possible that a pad is added or removed
just after the iterator finishes iterating, but before the
function returns.

This is also a replacement for gst_aggregator_iterate_sink_pads().

properly return elements from sink to sources.

If we have some elements that are not linked, we *still* want to
ensure that we return:
* In priority any sinks
* Last of all any sources
* And in between any element which is neither source nor sink

For this to work, when looking for the next candidate element,
not only check the degree order, but if there are two candidates
with the same degree order, prefer the non-source one.

Amongst other things, this fixes the case where we activating a
bin containing unlinked sources and other elements. Without this
we could end up activating sources (which might start adding pads
to be linked) before other (to which those new source element pads
might be linked) are not activated

When a plugin declares a dependency using this flag, all the

We try to determine the path of the executable portably,

exposed in gst_private.h, _gst_executable_path

e7ede5a487 plugin: Unify static and dynamic plugin interface
This patch changes the entry point of each plugin in order to unify the
interface for static and dynamic plugin. What we do is replace the
current static plugin interface and extend the dymamic one. The plugin
entry was a C structure, name "gst_plugin_desc". With this patch, the
interface is now:

  GstPpluginDesc *gst_plugin_<name>_get_desc(void);

The reason we change the C structure into function, is that it is
potentially more common to have function pointers, avoiding possible
binding language limitation. Additionally to that. This change prevents
the symbols from clashing between plugins, allowing to build once the
plugin (assuming you have -fPIC).

On the plugin loader side, we symply derive the shared object basename
to extract the plugin name. If this symbol is not found, we fallback to
gst_plugin_desc for backward compatibility.

This has one side effect, which is that the shared objects now need to
be named after their plugin name. This is generally the case with few
exceptions. The benifit of this limitation is that you can control the
gst_plugin_<name>_desc clash at file level.

It is possible to use gst_deinit() without registering the base

gst_deinit() will lead to a segmentation fault, since there is a
dereference to a pointer that is null.

This patch validates if the type is non-null before dereferencing
it.

function guard, but there's a pending patch to remove that
and it's hardly going to be a performance issue in practice,
even less so on a system that's compiled without run-time checks.

Alternative would be to move to the new g_object_new_properties()
with a fallback define for older glib versions, but it makes the
code look more unwieldy and doesn't seem worth it.

Fixes deprecation warnings when building against newer GLib versions.

efbacf1931 streamcollection: fix racy user-after-free
The issue happens when the structure is printed by the logging
subsystem: the object is included in the log, and this will cause the
full object printout to be done there. However, after dispose, the queue
was already cleared, so the access to it (to print the object) would
assert, as the queue was already freed. The patch changes it so that the
queue is merely empty, and only freed in _finalize.

The GST_TYPE macro points to global variables initialized by the

allows the user to decide to retrieve a backtrace
without those infos instead which is much faster.

6dcf8263e8 message: Ensure that the "debug" field of error/warning/info messages is valid UTF-8
The caller might pass arbitrary data here that caused the error, and
trying to set invalid UTF-8 in a GstStructure causes it to be not set at
all. Later when trying to parse it, the field will not exist and the
return value will point to invalid memory. Prevent this by storing NULL
instead.

Also print a g_warning(), the caller should never ever do this to begin
with.

e1dc60524e dynamic types: Implement dynamic types in the registry
Implement GstDynamicTypeFactory as a new registry feature.

GstDynamicTypeFactory provides a way of registering a GType
into the registry, such that it will be registered as a dynamic
type when the registry is loaded, and then automatically loaded
if the type is needed during caps parsing.

This allows using non-core types in pad templates, by loading a
registry feature to create the GType on the fly.

However, when we're built with MinGW and someone wants to link to us

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Mathieu Duponchelle <mathieu.duponchelle@opencreed.com>

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

cd06aea103 poll: Fix various race conditions with read_control() and write_control()
This addresses slightly different race conditions on Linux and Windows, and
fixes gst_poll_read_control() when control_pending == 0.

On Linux, the socketpair() used for control should not be made O_NONBLOCK.
If there's any propagation delay between set->control_write_fd.fd and
set->control_read_fd.fd, even the mutex now held will not be sufficient to
prevent a race condition.  There's no benefit to using O_NONBLOCK, here.
Only liabilities.

For Windows, it's necessary to fix the race condition between testing
set->control_pending and performing WAKE_EVENT()/RELEASE_EVENT().  This is
accomplished by acquiring and holding set->lock, for both of these operations.
We could optimize the Linux version by making this Windows-specific.

For consistency with the Linux implementation, Windows' RELEASE_EVENT()
has also been made to block, although it should never happen.

Also, changed release_wakeup() to return TRUE and decrement control_pending
only when > 0.  Furthermore, RELEASE_EVENT() is called only when
control_pending == 1.

Finally, changed control_pending to use normal, non-atomic arithmetic
operations, since it's now protected by set->lock.

Note: even though the underlying signaling mechanisms are blocking,
release_wakeup() is effectively non-blocking, as it will only attempt to read
from control_read_fd.fd after a byte has been written to control_write_fd.fd
or WaitForSingleObject() after it's been signaled.

__declspec(dllexport/import) are supported by GCC and are needed for

built with __declspec(dllexport) which happens when anything using
GST_EXPORT is built with MSVC.

See: https://msdn.microsoft.com/en-us/library/619w14ds.aspx

Essentially, if you built gstreamer with MSVC and then tried to use
constants from it (such as GST_TYPE_CAPS) in a plugin, GCC would
retrieve the address of the value instead of the value itself.

Calling those functions directly from the streaming thread will cause
deadlocks in many situations, as they might involve waiting for the
streaming thread to shut down from this very streaming thread.

With this change is is then possible to match up GST_REFCOUNTING log messages
for object allocation/disposal/finalization. This can help with diagnosing
"memory leaks" in applications that have not correctly disposed of all the
GStreamer objects it creates.

368ee8a336 pad: rework probe's hook_marshall function
PUSH and PULL mode have opposite scenarios for IDLE and BLOCK
probes.

For PUSH it will BLOCK with some data type and IDLE won't have a type.
For PULL it will BLOCK before getting some data and will be IDLE when
some data is obtained.

The check in hook_marshall was specific for PUSH mode and would cause
PULL probes to fail to be called. Adding different checks for the mode
to fix this issue.

f02d09c362 registry: allow plugin and feature filter funcs to call registry API
Don't keep the registry locked whilst iterating over the plugins

make a copy of the feature/plugin list and then filter it without
holding the registry lock. This is still considerably faster than
the alternative which would be to use a GstIterator.

where the deactivation will assert (g_critical) if the parent is lost at

d7c8ce0947 preset: Use GST_PRESET_PATH as an extension of the system path, not a replacement of the user path
First load all system presets, then all from the environment variable, then
from the app directory, then from the user directory. Any one in the chain
with the highest version completely replaces all previous ones, later ones
with lower versions are merged in without replacing existing presets.

This is basically the same behaviour as before, just that GST_PRESET_PATH is
inserted as another source of directories between the system and app presets.

It was added in ca08af1f17, but was
accidentially overriding the user preset path there. Which caused inconsistent
behaviour as new presets were still stored in the system path, just not loaded
from there. Meaning you could store a new preset (in the user path), just for
GstPreset to not find it anymore later (because it only looked in the
GST_PRESET_PATH instead of the user path).

ab55ad7eaa ghostpad: Do nothing in _internal_activate_push_default
When calling gst_pad_activate_mode() on a ghostpad
gst_ghost_pad_activate_push_default() will be called. This will call
gst_pad_activate_mode() on the proxypad (which is internal of the
ghostpad), calling gst_ghost_pad_internal_activate_push_default(), which
again will call gst_pad_activate_mode() on the original ghostpad.

By simply returning TRUE in
gst_ghost_pad_internal_activate_push_default() the redundant call to
gst_pad_activate_mode() (for the same pad) is avoided.

Exposes the internal __gst_vasprintf as gst_info_vasprintf which has a fallback
to g_vasprintf if the debug system is disabled.

API: gst_info_vasprintf
API: gst_info_strdup_vprintf
API: gst_info_strdup_printf

46a851b279 parse-launch: warn when still waiting to plug sub-pipelines after no-more-pads
The parse-launch API automagically handles dynamic pads and performs delayed
linking as needed, without any feedback about whether the linking succeeded or
not however. If a delayed dynamic link can't be completed for whatever reason,
parse-launch will simply wait in case a suitable pad appears later. This may
never happen though, in which case the pipeline may just hang forever.

Try to improve this by connecting to the "no-more-pads" signal of any element
with dynamic pads and posting a warning message for the related outstanding
dynamic links when "no-more-pads" is emitted.

b427997119 element: Don't hold state lock all the time while sending an event
This lock seems to exist only to prevent elements from changing states while
events are being processed. However events are going to be processed
nonetheless in those elements if sent directly via pads, so protection must
already be implemented inside the elements for event handling if it is needed.

As such having the lock here is not very useful and is actually causing
various deadlocks in different situations as described in

446b3e6ddc plugin: Don't do lossy shift on hash
In plugin is responsible for calculating a hash of the dependencies
in order to determine if the cache should be invalidated or not.
Currently, the hash combining method removes a bit of the original
have before combining with an addition. As we use 32bits for our hash
and shift 1 bit for each file and directory, that resulting hash only
account for the last 32 files. And is more affected by the last file.

Rotating technique (shifting, and adding back the ending bit), can be
use to make the addition non-commutative. In a way that different order
gives different hashes. In this case, I don't preserve this behaviour
because the order in which the files are provided by the OS is
irrelevant.

In most cases, the XOR operation is used to combine hashes. In this
code we use the addition. I decided to preserve the addition because
we make use of non-random hash ((guint) -1) in the algorithm for
matching files that are not really part of the hash (symlinks, special
files). Doing successive XOR on this value, will simply switch from
full ones, to full zero. The XOR used with whitelist has been preserved
as it's based on a fairly randomized hash (g_str_hash).
