This is how to run the test (by scottmc on the dev list):

If you build Haiku with python added as an optional package you can
run this test:
cd /boot/common/lib/python2.6/test
its called test_posix.py, so just run "python test_posix.py"

comment:2 Changed 6 years ago by mmadia

  • Component changed from - General to System/POSIX

comment:3 Changed 6 years ago by axeld

  • Resolution set to fixed
  • Status changed from new to closed
  • Version changed from R1/pre-alpha1 to R1/Development

Fixed in hrev34276.

comment:4 Changed 6 years ago by scottmc

  • Resolution fixed deleted
  • Status changed from closed to reopened

Tested with hrev34277 and the python test_posix.py still fails the getcwd test. I'm not sure if it was the same error message or not. This was with a python built prior to hrev34276. I'll post the output if that'd be helpful, or you can run it with the command list above.

You cannot have tested with hrev34277, as the kernel will never return "No buffer space available" anymore. Please confirm.

comment:7 Changed 6 years ago by axeld

BTW I did run the python test before closing this ticket, and it does not fail anymore here.

  • Resolution set to fixed
  • Status changed from reopened to closed

Oh. I had tested with the new python build but that was "just" before I had applied the hrev34277 commit. So that explains why the results were different. Here's the new test results to show that yes the getcwd is fixed:

Sorry for the noise. I'll rerun the test in verbose mode to update the status on the two remaining failures in the pytohn posix test, but this ticket is indeed fixed.

comment:9 Changed 6 years ago by axeld

No problem. I recently removed O_EXLOCK, and O_SHLOCK, since we probably won't ever support them anyway, so that might need another Python update, too.

Note: See TracTickets for help on using tickets.
