Comment(by drkirkby):
Has there been any more thoughts on this?
I had a doctest failure today on my !OpenSolaris machine ''hawk'', which
is almost certainly a result of this bug. This is using sage-4.6.rc0.
{{{
The following tests failed:
sage -t -long local/lib/python2.6/site-
packages/sagenb-0.8.2-py2.6.egg/sagenb/notebook/misc.py # 0 doctests
failed
sage -t -long devel/sage/sage/plot/plot.py # 5 doctests failed
}}}
The likely reason for the first of these failures can be seen if we look
further up the log.
{{{
sage -t -long local/lib/python2.6/site-
packages/sagenb-0.8.2-py2.6.egg/sagenb/misc/misc.py
[2.9 s]
sage -t -long local/lib/python2.6/site-
packages/sagenb-0.8.2-py2.6.egg/sagenb/notebook/misc.py
python: can't open file '/export/home/drkirkby/.sage//tmp/misc.py': [Errno
2] No such file or directory
[0.2 s]
}}}
The log clearly shows a file {{{misc.py}}} being tested, followed by a
second test with a different file also called {{{misc.py}}}. That file is
then not found. It seems almost inevitable one test deleted the file
needed by another test as they were both called {{{misc.py}}} and both
tested around the same time.
Note this is the same machine on which the buildbot passed all doctests.
http://build.sagemath.org/sage/builders/hawk%20full/builds/8/steps/shell_6/logs/stdio
so it seems to be an intermittent problem. (I've also had all tests pass
on this).
These doctests issues are really annoying, as one never knows if its a
real Sage bug, or a doctest bug.
