Neal Norwitz 9602cc2aa4 Prevent spurious leaks when running regrtest.py -R. There may be more
issues that crop up from time to time, but this change seems to have been
pretty stable (no spurious warnings) for about a week.

Other modules which use threads may require similar use of
threading_setup/threading_cleanup from test_support.

Tim Peters d8a9d2a0e9 SF bug 613233: test_threadedtempfile hangs
A possibility to deadlock (on the hidden import lock) was created here
in 2.3, seemingly when tempfile.py started to call functions in
random.py.  The cure is "the usual":  don't spawn threads as a side
effect of importing, when the spawned threads themselves do imports
(directly or indirectly), and the code that spawned the threads is
waiting for the threads to finish (they can't finish, because they're
waiting for the import lock the spawner still holds).  Worming around
this is why the "test_main" mechanism was introduced in regrest, so
it's a straightforward fix.

NOT a bugfix candidate; the problem was introduced in 2.3.

Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Now Tim and Jack can have at it. :)

Guido van Rossum 9df3eabd6e Add "import thread" at the top of the module; this prevents us from
failing later when Python is compiled without threading but a failing
'threading' module can be imported due to an earlier (caught) attempt.

Tim Peters 73cbc5e616 Fix stupidity. 2001-01-13 03:45:59 +00:00
Tim Peters 9fadfb0d1d Guido found a brand new race in tempfile on Linux, due to Linux changing
pid across threads (but in that case, it's still the same process, and so
still sharing the "template" cache in tempfile.py).  Repaired that, and
added a new std test.
On Linux, someone please run that standalone with more files and/or more
threads; e.g.,

    python lib/test/test_threadedtempfile.py -f 1000 -t 10

to run with 10 threads each creating (and deleting) 1000 temp files.
