This started failing once again on koobs-freebsd-current:
======================================================================
ERROR: test_chown (test.test_os.ChownFileTests)
----------------------------------------------------------------------
Traceback (most recent call last):
File
"/usr/home/buildbot/python/3.x.koobs-freebsd-current/build/Lib/test/test_os.py",
line 1168, in test_chown
os.chown(support.TESTFN, uid, gid_1)
PermissionError: [Errno 1] Operation not permitted: '@test_15221_tmp'
Looking into this a bit further:
buildbot defaults (via twisted) to a umask of 077 for the build worker build/
directory, resulting in build directories with permissions as follows:
drwx------ 3 buildbot buildbot 4 May 17 12:36
2.7.koobs-freebsd-current
drwx------ 3 buildbot buildbot 4 Aug 21 11:28
2.7.koobs-freebsd-current.nondebug
Looking inside these directories to where TESTFN's (I think) are written, we
find:
[root@CURRENT-amd64:/usr/home/buildbot/python/2.7.koobs-freebsd-current/build/build]
ls -la
total 18
drwx------ 8 buildbot buildbot 8 Sep 27 17:03 .
drwx------ 19 buildbot buildbot 45 Sep 27 16:59 ..
drwx------ 2 buildbot buildbot 68 Sep 27 16:59
lib.freebsd-12.0-CURRENT-amd64-2.7-pydebug
drwx------ 2 buildbot buildbot 6 Sep 27 16:59 scripts-2.7
drwx------ 4 buildbot buildbot 4 Sep 27 16:59
temp.freebsd-12.0-CURRENT-amd64-2.7-pydebug
drwx------ 2 buildbot buildbot 2 Sep 27 16:59 test_python_45339
drwx------ 2 buildbot buildbot 2 Sep 27 17:03 test_python_46278
drwx------ 2 buildbot buildbot 2 Sep 27 17:03 test_python_47336
Does this explain the "Operation not permitted" error above?
If so, the question is, why/how is this test being run if it requires an
environment within which two groups can read and/or write files?
Again looking at group membership for the buildbot user on the worker host in
question (koobs-freebsd-current), the user only has a single group:
# groups buildbot
buildbot
