[New-bugs-announce] [issue28950] -j0 fails the check -j are not allowed together with -T/-l

[Xiang Zhang]

New submission from Xiang Zhang:

For python test command line arguments, -j is not allowed together with -T/-l (don't know why):

[cpython]$ ./python -m test -j4 -T
usage: python -m test [options] [test_name1 [test_name2 ...]]
python path/to/Lib/test/regrtest.py [options] [test_name1 [test_name2 ...]]
regrtest.py: error: -T and -j don't go together!
Pass -h or --help for complete help.
[cpython]$ ./python -m test -j4 -l
usage: python -m test [options] [test_name1 [test_name2 ...]]
python path/to/Lib/test/regrtest.py [options] [test_name1 [test_name2 ...]]
regrtest.py: error: -l and -j don't go together!
Pass -h or --help for complete help.

But -j0 which also spawns multiple progresses fails the check.
