Bug 600576 – app-arch/libarchive-3.2.2 fails tests on alpha and amd64 (possible Portage bug)

• Status: RESOLVED DUPLICATE of bug 598806
• Product: Gentoo Linux

[Description Tobias Klausmann (RETIRED) 2016-11-23 13:10:07 UTC]

3.2.1-r5 passes tests just fine, 3.2.2 fails as detailed below.

I am not sure this is libarchive's fault, really; hence, the Portage people are on CC. It looks like whatever is cleaning up the temp dir is constructing paths that are too long for Python's unlink() to handle, but that is mostly conjecture on my part.

[Comment 1 Jason Zaman 2016-11-23 16:35:37 UTC]

I have the same on stable amd64. The stacktrace is the same for me so not posting it.

The build.log ends with:
============================================================================

So the actual tests do pass, the problem is somewhere in portage after the tests and before the next phase. rm -rf /var/tmp/portage/* worked fine somehow.

When following the 0072_xxx... down far enough, i got back to where i started:
lrwxrwxrwx. 1 portage portage 113 Nov 24 00:16 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx -> /var/tmp/portage/app-arch/libarchive-3.2.2/temp/libarchive_test.2016-11-24T00.15.02-000/test_write_disk_secure744/

The full path is:

0072_xxx is the one portage chokes on, but the other numbered dirs also have a ton of xxxxxxxxxx dirs in them.

[Comment 2 Zac Medico 2016-11-23 21:25:14 UTC]

It seems that portage can be fixed to handle this by making the apply_recursive_permissions function use os.fwalk and similar functions that use file descriptors instead of paths. I've tested with python-3.5.2, and os.fwalk successfully traversed all of /var/tmp/portage/app-arch/libarchive-3.2.2/temp. It worked with a string argument, but failed with a bytes argument as reported in http://bugs.python.org/issue28682:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python3.5/os.py", line 519, in fwalk
    yield from _fwalk(topfd, top, topdown, onerror, follow_symlinks)
  File "/usr/lib64/python3.5/os.py", line 562, in _fwalk
    dirpath = path.join(toppath, name)
  File "/usr/lib64/python3.5/posixpath.py", line 89, in join
    genericpath._check_arg_types('join', a, *p)
  File "/usr/lib64/python3.5/genericpath.py", line 145, in _check_arg_types
    raise TypeError("Can't mix strings and bytes in path components") from None
TypeError: Can't mix strings and bytes in path components

If we can't use a byte's argument, then we're screwed if any of the paths aren't encoded with UTF-8.

[Comment 3 Zac Medico 2016-11-23 21:35:59 UTC]

I've filed bug 600626 to track the portage issue.

[Comment 4 Zac Medico 2016-11-23 21:54:37 UTC]

As a workaround, the ebuild could do something like this near the end of src_test:

    rm -rf "${T}"/libarchive_test*

It doesn't work for me. It fails with a number of "Directory not empty" errors, but it succeeds if I re-run the command afterwards.

It works if use FEATURES="-sandbox -usersandbox", so apparently there's interference from sandbox.

[Comment 7 Zac Medico 2016-11-23 23:19:46 UTC]

The tests actually cleanup "${T}"/libarchive_test* themselves when sandbox is disabled. So we can consider the root cause to be interference from sandbox (neglecting the fact that it's totally insane to create paths this long).

[Comment 8 SpanKY 2016-11-25 05:25:22 UTC]

most likely would be covered by bug 553092
