REIX Tony added the comment: Yes. I'm on my own for AIX debugging. I'm afraid too. ;) OK. What I need is build more skills about how to get into deep details when things run badly. Lot of fun. ;) Thx -- ___ Python tracker

R. David Murray added the comment: You are on your own for AIX debugging, I'm afraid. You can try the #python-dev channel on freenode for questions about how things work in general. If you find real problems with the python code you can open new issues (we have accepted patches for AIX when

REIX Tony added the comment: Hum I'm now building Python 2.7.10 RPMs on AIX. The .spec file works fine. However, when adding make test in the .spec file, I've got the tests blocked in test_io. The same with 2.7.6 . Going into the directory and trying "make quicktest", it is now blocked afte

REIX Tony added the comment: Thnaks for the information. I'm surprised that: $ make test > Go.res3 2>&1 & makes issues that do not appear with: $ nohup make test > Go.res3 2>&1 & Anyway, we know the root cause now, and there is a work-around. So, closing the defect is OK for me. About the co

R. David Murray added the comment: We certainly don't regularly test running them that way :) It might be interesting to make it possible, if it doesn't require too many changes to the tests. Excessive swapping seems like an odd symptom; I'm sure the explanation will be interesting if someone

Stefan Krah added the comment: > $ make test > Go.res3 2>&1 & The test suite does seem to behave poorly when run in the background: I'm getting constant swapping, excessive kworker activity, and indeed, one hang. With nohup prepended at least the tests have finished now. I'm not sure if the te

R. David Murray added the comment: Since Ubuntu is one of the platforms that gets thoroughly tested and neither the buildbots nor other users have reported issues, your best source for help on this is probably either the python-list mailing list, or an Ubuntu forum. FYI the 3.4 buildbots are c

[issue24741] Hangs and errors while testing on Ubuntu/Intel

New submission from REIX Tony: I'm now porting Python (2.7.10 and 3.4.3) on AIX. Before that, I wanted to build and test on reference machines in order to see what is expected during building and testing. However, on Ubuntu/i586 and Ubuntu/x86_64, I face hangs and errors during test phase on
