This allows the macosx versions to properly error out when fds are closed.
This is only a temporary fix until the pluginloader is switched to not
use GstPoll but GIOChannels.
In the plugin loader subprocess, move stdin and stdout to new fd's
so that plugins printing things during plugin init or (*gasp*)
possibly reading from stdin don't interfere with the data sent to
and from the parent.
When the plugin-scanner load fails (because the helper can't be
spawned), make sure to load the plugin that failed in-process, so
that all plugins do get loaded.
Fix an off-by-one error in the size guard for unpack_element, and
improve various debug statements in the failure paths.
Also, swap some g_new0 to g_malloc0 for the fun of it.
In most places in core and baseclasses we just need the caps to do caps-
intersections. In that case ref'ed caps are enough (no need to copy).
This patch also switches the code to use the new functions.
API: gst_pad_get_caps_refed(), gst_pad_peer_get_caps_refed()
Everyone running an uninstalled git setup is going to wonder about
this failure next time they update, so let's mention the solution
in the error message.
Reflow the code to move error handling to the end of the functions. Initialize
gvalue like we do in the setter. Add a unit-test module with two simple tests
the catche this bug.
We don't need the hold the proxy mutex locked for getting the internal pad and
for linking the new target pad when we retarget. So take the lock a little later
and release it earlier.
Fixes#596366
Guard against a hostile child process that sends bogus data
due to memory corruption by adding a magic number to each packet,
and limit the maximum size of any message to 32MB
When trying to find a function plugin-scanner, include a check on the
version of the binary registry chunks it sends, to make sure it's
what we understand.
Add a simple version check when starting the plugin-scanner so we can
verify we're talking to one that talks the same language.
First try a plugin-scanner in the installed path, then try one via the
GST_PLUGIN_SCANNER env var if that doesn't work.
Update the uninstalled script.
Install the plugin-scanner to the libexec dir
When updating the registry, we don't need to re-read the registry cache
and waste time replacing all our existing, hopefully identical, plugins
and features that we're about to re-scan anyway.
phase 2 - make the plugin loader receive the list of plugins to load and
send back the results asynchronously, so we don't context switch back
and forth so much.
The structure_change message was originally emitted on source pads and
then recently changed to be sink pads. This causes a failure in the
gst-python testsuite. Disable the restriction so that the published
behaviour is still allowed.
Also parse the nano of the version and assume that X.Y.Z-1.1 >= X.Y.Z
With this change we can also check development versions against the version of
the upcomming release.
