Public bug reported: The latest uploads of upstart are failing to build on s390x, with lost fds causing the testsuite to fail to return (which should eventually lead to a timeout, but hasn't as of this writing):
https://launchpad.net/ubuntu/+source/upstart/1.13.2-0ubuntu22/+build/9658082 https://launchpad.net/ubuntu/+source/upstart/1.13.2-0ubuntu23/+build/9668581 upstart also fails to build on devac02, with the following test failures: not ok 12 - ensure log written when directory created accessible with uid 0 wrong value for output, got unexpected (nil) at tests/test_log.c:827 (test_log_new). /bin/bash: line 5: 31104 Aborted (core dumped) ${dir}$tst FAIL: test_log [...] not ok 19 - with deletion of top-level directory wrong value for source->watch, expected (nil) got 0x2aa43d27cb0 at tests/test_conf.c:1006 (test_source_reload_job_dir). Aborted (core dumped) FAIL: test_conf_preload.sh The second of these failures definitely looks like a lost inotify event. So I looked at libnih, and libnih's testsuite hangs indefinitely on devac02, after: PASS: test_file 78 - with simple directory loop This is the last test in test_file; the next test that it hangs on is test_watch. Running this test directly shows that it hangs after: ok 17 - nih_watch_reader strace shows the test_watch waiting indefinitely on a select, waiting to read the inotify fd. All of this is on systems running linux 4.4.0-21. The upstart testsuite was passing as recently as 4.4.0-18. https://launchpad.net/ubuntu/+source/upstart/1.13.2-0ubuntu21/+build/9278268 I don't know what in the kernel could have changed to break this, but that seems the most likely explanation. There was also a new glibc version since the last successful upstart build, 2.23-0ubuntu3, which includes an s390x-specific change, but that seems quite unlikely to impact inotify. ** Affects: upstart (Ubuntu) Importance: Undecided Assignee: Dimitri John Ledkov (xnox) Status: New ** Changed in: upstart (Ubuntu) Assignee: (unassigned) => Dimitri John Ledkov (xnox) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to upstart in Ubuntu. https://bugs.launchpad.net/bugs/1576914 Title: upstart,libnih ftbfs on s390x with linux 4.4.0-21.37 Status in upstart package in Ubuntu: New Bug description: The latest uploads of upstart are failing to build on s390x, with lost fds causing the testsuite to fail to return (which should eventually lead to a timeout, but hasn't as of this writing): https://launchpad.net/ubuntu/+source/upstart/1.13.2-0ubuntu22/+build/9658082 https://launchpad.net/ubuntu/+source/upstart/1.13.2-0ubuntu23/+build/9668581 upstart also fails to build on devac02, with the following test failures: not ok 12 - ensure log written when directory created accessible with uid 0 wrong value for output, got unexpected (nil) at tests/test_log.c:827 (test_log_new). /bin/bash: line 5: 31104 Aborted (core dumped) ${dir}$tst FAIL: test_log [...] not ok 19 - with deletion of top-level directory wrong value for source->watch, expected (nil) got 0x2aa43d27cb0 at tests/test_conf.c:1006 (test_source_reload_job_dir).
