On Sat, 23 May 2026 at 13:46:03 +0000, Santiago Vila reported:
assert xattr.getxattr(b'input/file', b'security.capability') ==
capabilities
E AssertionError: assert b'' == b'\x01\x00\x0...0\x00\x00\x00'
(this happened twice in Santiago's log, once in
ArchiverTestCase::test_extract_capabilities and once in
RemoteArchiverTestCase::test_extract_capabilities)
This test failure is now a blocker for the Python 3.14 transition,
because borgbackup is one of the packages needing rebuilding for that
transition. Builds on the official Debian buildds exhibited the same
test failure, for example in
<https://buildd.debian.org/status/fetch.php?pkg=borgbackup&arch=arm64&ver=1.4.4-3%2Bb1&stamp=1782584582&raw=0>
and
<https://buildd.debian.org/status/fetch.php?pkg=borgbackup&arch=s390x&ver=1.4.4-3%2Bb1&stamp=1782588098&raw=0>.
I can reproduce these two test failures on a real machine running
unstable (building on either a btrfs or tmpfs filesystem), and on a
qemu virtual machine running Debian 13 (on ext4, I think).
If I avoid running tests under fakeroot (patch below) then that avoids
this particular test failure.
I can also reproduce most (all? I haven't checked yet) of the other test
failures seen in the buildd logs above, but it seems likely that their
root cause is different, so I'll report them separately if not already
in-scope for #1140857. Avoiding fakeroot *doesn't* address those.
