Subject: mpd: 0.23.9-1+b3 fails to start with 'io_uring_get_sqe() failed'

Date: Fri, 11 Nov 2022 19:59:17 +0100

Package: mpd
Version: 0.23.9-1+b3
Severity: important
X-Debbugs-Cc: dkk089@gmail.com

MPD stopped being able to run after upgrading to 0.23.9-1+b3. The relevant journal messages are :

mpd[8301]: terminate called after throwing an instance of 'std::runtime_error'
mpd[8301]:   what():  io_uring_get_sqe() failed

Downgrading to 0.23.9-1+b2 or setting "auto_update" to "no" fixes this problem.

This upstream commit looks like an ABI breakage:

 https://github.com/axboe/liburing/commit/f5cd4eb2b50840510a4c6bbe5ba34a5a2058a2ae

The bug report should be moved to liburing.

b2 was built with liburing 2.2, but b3 was built with liburing 2.3.  See build logs:

 https://buildd.debian.org/status/fetch.php?pkg=mpd&arch=amd64&ver=0.23.9-1%2Bb2&stamp=1666619004&raw=1
 https://buildd.debian.org/status/fetch.php?pkg=mpd&arch=amd64&ver=0.23.9-1%2Bb3&stamp=1668073210&raw=1

This could be a liburing ABI breakage?

Thanks for the quick reply, Max.

I can confirm that installing liburing2=2.3-1 causes mpd=0.23.9-1+b3
to run flawlessly.

Will file a new bug against liburing.

which is now fixed, but mpd will need a rebuild to pick up the tightened
dependency. I'll look into uploading 0.23.10 over the next few days.
