Description Richard W.M. Jones 2020-01-30 09:05:58 UTC

Description of problem:

+ createrepo repo
GLib: Critical: g_async_queue_lock: assertion 'queue' failed
GLib: Critical: g_async_queue_push_unlocked: assertion 'queue' failed
GLib: Critical: _g_async_queue_get_mutex: assertion 'queue' failed
/var/tmp/rpm-tmp.pJW7CO: line 45: 249304 Segmentation fault      (core dumped) createrepo repo

Version-Release number of selected component (if applicable):

createrepo_c 0.15.5-1.fc32

How reproducible:

Happened at least once.

Steps to Reproduce:
1. Run createrepo.

Comment 1 Richard W.M. Jones 2020-01-30 09:10:17 UTC

Actually this bug seems to be in glib2, not in createrepo itself.

glib2 2.63.3-1.fc32 => WORKS
glib2 2.63.4-1.fc32 => BUGGY

A trivial reproducer is:

$ mkdir /var/tmp/test
$ cd /var/tmp/test
$ koji download-build libnbd-1.3.1-4.fc32 --arch=x86_64
$ createrepo .
Directory walk started
Directory walk done - 6 packages
Temporary output repo path: ./.repodata/
Preparing sqlite DBs
Pool started (with 5 workers)
Pool finished
GLib: Critical: g_async_queue_lock: assertion 'queue' failed
GLib: Critical: g_async_queue_push_unlocked: assertion 'queue' failed
GLib: Critical: _g_async_queue_get_mutex: assertion 'queue' failed
Segmentation fault (core dumped)

I can't get a stack trace because this causes all sorts of other programs to
segfault too ...

Comment 2 Richard W.M. Jones 2020-01-30 09:11:49 UTC

Seems likely to be a duplicate of bug 1795052.
