I should - probably disable popen2 support... it uses fork(), and fork() doesn't mix - with threads on BeOS. In *THEORY* you could use it in a single-threaded - program, but I haven't tried. - - If test_popen2 does hang, you can find the semaphore it's hung on via the - "ps" command. Look for python and you'll find something like this: - -./python -tt ../src/Lib/test/regrtest.py (team 26922) (uid 0) (gid 0) - 39472 python sem 10 3785 1500 piperd(360526) -./python -tt ../src/Lib/test/regrtest.py (team 26923) (uid 0) (gid 0) - 39477 python sem 10 25 4 python lock (1)(360022) - ^^^^^^ - That last number is the semaphore the fork()'d python is stuck on - (see how it's helpfully called "python lock (1)"? :-). You can unblock - that semaphore to let the tests continue using the "release" command - with that semaphore number. Be _very_ careful with "release" though, - releasing the wrong semaphore can be hazardous. - - Expect the following errors: - - test * skipped -- an optional feature could not be imported (you'll see - quite a few of these, based on what optional modules - you've included) - - test test_fork1 skipped -- can't mix os.fork with threads on BeOS + The BeOS is Not UNIX category: + - test_select crashed -- select.error : (-2147459072, 'Bad file descriptor') + - test_socket crashed -- exceptions.AttributeError : SOCK_RAW + - test_fcntl crashed -- exceptions.IOError: [Errno -2147483643] Invalid argument - test test_select crashed -- select.error : (-2147459072, 'Bad file - descriptor') + This one is funny!
