[Python-Dev] Whole bunch of test failures on OSX (original) (raw)

[Neal Norwitz, on -R testing]

... For the latest results, see: http://docs.python.org/dev/results/make-test-refleak.out

Several tests fail consistently with -R. These are the most recent from the link above: testdecimal testdifflib testlogging testoptparse testwarnings. It would be great if someone would figure out why these tests fail when running under -R and fix them.

Like anyone wants to spend their life guessing what reload() actually does <0.6 wink>.

Figuring out why that happens is pretty much a nightmare. "Fixing it" requires changes to both regrtest and test_warnings:

The change to regrtest may fix other -R cases (for example, it appears to repair test_decimal), but may introduce new failures too. If you try it and find it's a net win ;-), feel free to check it in.
