The unversioned tool wrappers are confusing and annoying for packagers,
users and developers alike. A gst-launch pipeline that works in 0.10
will likely not work in 0.11 (e.g. because elements or properties get
renamed, or syntax changes). The unversioned tools also yield useless
results when used with gdb or valgrind. Packagers need to co-ordinate
the packaging of all major versions to make sure there are no conflicts
when both try to install the same files. When two major versions are
in use (e.g. 0.10 and 0.11/1.0), it may be unclear (when looking at
things on IRC/pastebin/mailing list etc.) which version is actually
being used when there are unversioned wrappers. For all these reasons,
it seems best to just remove them for now.
Remove SIGUSR* handling from gst-launch, since it might interfere
with other things (e.g. libleaks), and should be done differently
anyway (either via support for simple timed-commands scripting or
remote control via DBus or so).
People should just query the registry themselves or write a small
python script if they need this functionality (which is likely
less work than parsing the XML that this script outputs, and I'm
not aware of anything using the xml2text xsl either).
See #651514 for details. It's apparently impossible to write code
that avoids both type punning warnings with old g_atomic headers and
assertions in the new. Thus, macros and a version check.
The most common case is to not specify any flags when doing the allocation. Make
the allocation from a pool with a maximum amount of buffers block by default for
this reason.
Optimize linking by only releasing the pad locks when there are link functions
installed on the pads.
Add some G_LIKELY here and there.
Move error paths out of the main code flow.
Keep track of installed number of probes to shortcut emission.
Allow NULL callbacks, this is useful for blocking probes.
Improve probe selection based on the mask, an empty mask for the data or the
scheduling flags equals that all probes match.
Add some more debug info.
Don't check the flushing flag in the probe callback handler, this needs to be
done before calling the handler.
Fix blocking probes.
Fix unit tests
