Move the locking methods from GstMemory to GstMiniObject.
Add a miniobject flag to enable LOCKABLE objects. LOCKABLE objects can
use the lock/unlock API to control the access to the object.
Add a minobject flag that allows you to lock an object in readonly mode.
Modify the _is_writable() method to check the shared counter for LOCKABLE
objects. This allows us to control writability separately from the refcount for
LOCKABLE objects.
So mini objects don't have to poke into the GstMiniObject part
of the structure. Saves lines of code, and seems slightly cleaner.
We don't have proper OO hierarchies or methods here after all.
The size field is used by subclasses to store the total allocated size of the
memory for this miniobject. Because miniobject doesn't really do anything with
this field we can move it to the subclasses.
Rename _do_simplify() to _simplify(). The name was introduced as a replacement
method for a deprecated method but we can now rename it again.
Fix some docs.
Make gst_caps_do_simplify() take ownership of the input caps and produce a
simplified output caps. This removes the requirement of having writable input
caps and the method can make the caps writable only when needed.
Rework some caps operations so they don't rely on writable caps but instead take
ownership of the input caps and do _make_writable() only when needed.
Remove some const from caps functions, it does not make much sense for
refcounted objects and does not allow us to return a refcount to the const input
caps.
Rework the base classes fixate vmethods to not operate on the caps in-place.
All this saves us around 30% of caps and structure copy and new operations.
Remove trace, we use debug log for that
Make alloc trace simpler, removing some methods.
Activate alloc trace with a GST_TRACE=3 environment variable.
Dump leaked objects atexit.
Provide an offset in the object where the GType can be found so that more
verbose info can be given for objects.
Remove -T option from gst-launch because tracing is now triggered with the
environment variable.
Which we had to add because GLib didn't have it
back in the day. Port everything to plain old
G_TYPE_DATE, which is also a boxed type. Ideally
we'd just use GDateTime for everything, but it
doesn't support not setting some of the fields
unfortuntely (which would be very useful for
tag handling in general, if we could express
2012-01 for example).
https://bugzilla.gnome.org/show_bug.cgi?id=666351
Add a singleton for ANY and EMPTY caps and make the GST_CAPS_ANY and
GST_CAPS_NONE point to them. This makes the API more consistent now
that the macro does not magically create a ref. It also solves some leaks in
places where the macro was used to register a padtemplate.
The second caps ownership is transfered, no need to require it to
be writable from the caller function. Instead, _append and _merge
make it writable on their own.
Discovered because of an assertion on encoding-profile.c in
_get_input_caps using _merge but not passing writable caps.
This was leaking the PtrArray from caps->priv, as set up by the other call to
gst_caps_init. Also, the thread safety issue presented in the comment above was
not taken care of anymore. We now zero the refcount again when publishing the
structure.
Fixes#661629.
