[issue30314] Buildbots: 15 min is too low for test_tools on x86 Tiger 3.6 buildbot

[STINNER Victor]

STINNER Victor added the comment:

The timeout of buildbot has been adjusted (my PR 
https://github.com/python/buildmaster-config/pull/8 has been merged).

The cpu resource has been disabled on Travis CI to make it faster.

This issue can now been fixed.

I merged my PR and applied the new buildbot configuration. I will try to check 
if the config was applied correctly.

Serhiy: "test_tools is so slow because it proceeds *all* Python files. This 
controlled by the "cpu" resource (only 10 random files are chosen if it is 
disabled)."

I created the bpo-30417 to track this idea.

Maybe disable the "cpu" resource on slow buildbots?

[issue30314] Buildbots: 15 min is too low for test_tools on x86 Tiger 3.6 buildbot

[STINNER Victor]

New submission from STINNER Victor:

We should give more than 15 min to the "x86 Tiger 3.6" buildbot, since 
test_tools was killed by the timeout. On the previous build, test_tools took 
min 25 sec.

The global 15 min timeout was designed to detect deadlocks issues, but here 
it's just that the buildbot is sometimes too slow.

Maybe we should increase the timeout to 30 min on all buildbots, but also 
increase the timeout of the "tests" step to long than 1 hour? Otherwise, the 
test can be killed by buildbot without logging the Python traceback.

Maybe we can configured buildbot to first send a signal (SIGUSR1? SIGINT?) 
before killing the process to dump a traceback, but that's something different.
