[New-bugs-announce] [issue23925] test_cmd_line failing on PYTHONSTARTUP

[Jamiel Almeida]

New submission from Jamiel Almeida:

Running the test test_cmd_line with my current PYTHONSTARTUP set to the attached file breaks the test.

$ ./python.exe -m test test_cmd_line

Changing line 280 on Lib/test/test_cmd_line.py to include either -I or -E makes the error be different but still breaks the test.

adding a line with `del env['PYTHONSTARTUP']` before the subprocess works around the issue.

This leads me to believe that -E and -I aren't fully ignoring the environment variable.

Running with:
$ PYTHONSTARTUP= ./python.exe -m test test_cmd_line

Also works around the issue.

Ran the following to build python and run tests

$ hg clone https://hg.python.org/cpython
$ cd cpython
$ ./configure --with-pydebug && make -j4
$ ./python -m test -j4
