Bug 618494 – media-libs/gstreamer-1.14.1: app-emulation/spice configure blocks while "checking for the appsrc GStreamer element..." when old media-libs/gst-plugins-bad-1.12.4 is installed

• Status: CONFIRMED
• Product: Gentoo Linux

[Description Mirko Guenther 2017-05-15 06:16:28 UTC]

when try to emerge 'app-emulation/spice-0.13.3-r1' the configure script blocks on 'checking for the appsrc GStreamer element...'
It's only happens the running the emerge process.

'ebuild app-emulation/spice-0.13.3-r1 configure' with my standard user or running the configure script as root in '/var/tmp/portage/app-emulation/spice-0.13.3-r1/work' works fine.

running 'ebuild app-emulation/spice-0.13.3-r1 configure' as user portage blocks.

*When export DISPLAY=:0 the configure script works*

[Comment 3 Matthias Maier 2017-07-12 03:31:45 UTC]

Was $DISPLAY set to an invalid value?

I cannot reproduce when compiling in a stage-3 (without unset DISPLAY variable).

Same here in an "emerge --emptytree" on amd64 while at

It turns out that it is gst-plugin-scanner waiting for some mutex, and that '/usr/bin/gst-inspect-1.0 appsrc' does run the 'gst-plugin-scanner' only if "~/.cache/gstreamer-1.0/registry.x86_64.bin" is missing - as it is the case for 'portage' user.

When I remove my own ~/.cache/gstreamer-1.0/, gst-inspect-1.0 does hang as well.

I'm going to kill that now to finish my "emerge --emptytree @world" - let's see if I can reproduce once rebooted.

Note that media-libs/gst-plugins-bad-1.12.4 update to 1.14.1 is still pending, scheduled after app-emulation/spice in 'emerge --resume'.

Now since media-libs/gst-plugins-bad-1.14.1 is updated things do work again.

I'd wonder if there's a way in RDEPEND, to get media-libs/gst-plugins-bad updated along media-libs/gstreamer before packages (not depending on media-libs/gst-plugins-bad) subsequently are merged during a larger world update.

Are you sure this isn't just coincidence, with the freezing being random and it just didn't happen randomly after you got -bad upgraded, but could happen again after a couple tries?

Doesn't seem so.
I've reproduced the hang by replaying the gstreamer upgrade path (from 1.12.4 to 1.14.1) seen during my world upgrade:

$ emerge -C gstreamer gst-plugins-bad gst-plugins-base gst-plugins-good gst-plugins-gtk
$ emerge -1 '~gstreamer-1.12.4' '~gst-plugins-bad-1.12.4' '~gst-plugins-base-1.12.4' '~gst-plugins-good-1.12.4'

$ rm -rf ~/.cache/gstreamer-1.0 ; gst-inspect-1.0 appsrc
PASS

Here, app-emulation/spice would be merged before gst-plugins-good, but in my world-emptytree update the order was:

Ok, one by one using --nodeps: some need FEATURES=-protect-owned, as emerge won't know about subsequent unmerge of old gst-plugins-bad:

$ FEATURES=-protect-owned emerge -1 --nodeps gstreamer
$ rm -rf ~/.cache/gstreamer-1.0 ; gst-inspect-1.0 appsrc
GOOD

$ FEATURES=-protect-owned emerge -1 gst-plugins-base --nodeps
$ rm -rf ~/.cache/gstreamer-1.0 ; gst-inspect-1.0 appsrc
GOOD

$ emerge -1 gst-plugins-good
$ rm -rf ~/.cache/gstreamer-1.0 ; gst-inspect-1.0 appsrc
HANG

$ FEATURES=-protect-owned emerge -1 gst-plugins-gtk --nodeps
$ rm -rf ~/.cache/gstreamer-1.0 ; gst-inspect-1.0 appsrc
