Comment(by leif):
At this point just a comment on the naming / mangling:
* To me, it doesn't make any sense to create "hidden" files, so I would
omit the leading period.
* We should perhaps apply some character substitutions to
`socket.gethostname()` as well, like `sage.misc.misc` does (see quote
above).
* Thinking more about it, I would replace slashs (`os.path.sep`) by
periods (and not double-underscores or, as currently, dashs), since that
way the temporary filenames resemble (at least partially) fully qualified
Python module names.
(As discussed, I'd also change the ''default'' for `SAGE_TESTDIR`, e.g. to
`tempfile.gettempdir()`.)
We could make sure once that the temporary directory
(`${SAGE_TESTDIR}/${hostname}-${pid}/`) is writable by the user. I think
we should also clean it up in case it already exists, as anything left
there is potentially very old and unrelated to the current test run. We
''might'' also adjust the permissions of the directory.
Looking only at your (John's) patch, is `temp_py_file` defined anywhere?
(I only see it gets added to `tmpfiles`.)
P.S.: Why not base the patch on Mitesh's? (Which AFAIR only needed two
changes.)
