Bug ID: 2108537
Summary: perl-Directory-Queue-2.1-3.fc37 fails tests on pp64le
in mock because number of links to a directory is
always 1
Product: Fedora
Version: rawhide
Hardware: ppc64le
URL: https://koschei.fedoraproject.org/package/perl-Directo
ry-Queue?collection=f37

Target Milestone: ---
Classification: Fedora
perl-Directory-Queue-2.1-3.fc37 fails in Fedora 37 on ppc64le like this:
t/1main.t ...... ok
# Failed test 'count 1'
# at t/1normal.t line 55.
# got: '-1'
# expected: '1'
# Failed test 'count 2'
# at t/1normal.t line 59.
# got: '-1'
# expected: '2'
# Failed test 'count 1'
# at t/1normal.t line 74.
# got: '-1'
# expected: '1'
# Failed test 'count 0'
# at t/1normal.t line 83.
# got: '-1'
# expected: '0'
invalid maxelts: -1
# Looks like your test exited with 255 just after 31.
t/1normal.t ....
Dubious, test returned 255 (wstat 65280, 0xff00)
Failed 22/49 subtests
A difference between passing and failing build root is at
<https://koschei.fedoraproject.org/build/13217496>.
This failure happens on pcc64le in mock. It does not happen outside mock or on
F35 x86_64 in mock with F37 user space.
I located the problem to Directory::Queue::Normal->count() which always return
-1. That's because _subdirs_stat() returns "$stat[ST_NLINK] - 2" where
$stat[ST_NLINK] is 1. It looks like something has changed in kernel, glibc, or
mock and as a result i-nodes of directories inside mock /tmp/ (as well as root)
filesystem are not "properly" counted:
# ls -la /tmp/a/
total 0
drwxr-xr-x. 1 root root 2 Jul 19 04:53 .
drwxrwxrwt. 1 root root 14 Jul 19 04:53 ..
drwxr-xr-x. 1 root root 0 Jul 19 04:53 b
# stat /tmp/a
File: /tmp/a
Size: 2 Blocks: 0 IO Block: 65536 directory
Device: 0,32 Inode: 164461 Links: 1
Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root)

Modify: 2022-07-19 04:53:53.840139244 -0400
Change: 2022-07-19 04:53:53.840139244 -0400
Birth: 2022-07-19 04:53:44.220450066 -0400
The number of links is expected to be 3 instead of 1. The number does not
changes when creating additional subdirectories in /tmp/a.
