Hi, Here is a quick report of what changed recently on buildbots. == pythoninfo == I added a new "python3 -m test.pythoninfo" command which is now run on Travis CI, AppVeyor and buildbots. https://bugs.python.org/issue30871 This command dumps various informations to help debugging test failures on our CIs. For example, you get the Tcl version, information about the threading implementation, etc. Currently, pythoninfo is only run on the master branch, but I plan to run it on Python 3.6 and 2.7 later. The pythoninfo idea comes from https://bugs.python.org/issue29854 when we didn't know the readline version of a buildbot, and I didn't want to put such information in regrtest header, since importing readline has side effects. == Removed buildbots == A few buildbots were removed: * All Python 3.5 buildbots was removed, since the 3.5 branch entered the security only stage: https://mail.python.org/pipermail/python-dev/2017-August/148794.html * FreeBSD 9-STABLE (koobs-freebsd9): FreeBSD 9 is no more supported upstream, use FreeBSD 10 and FreeBSD CURRENT buildbots * OpenIndiana: was offline since the beginning of June. Previous discussions on this list: * September 2016: OpenIndiana and Solaris support https://mail.python.org/pipermail/python-dev/2016-September/146538.html * April 2015: MemoryError and other bugs on AMD64 OpenIndiana 3.x https://mail.python.org/pipermail/python-dev/2015-April/138967.html * September 2014: Sad status of Python 3.x buildbots https://mail.python.org/pipermail/python-dev/2014-September/136175.html * intel-ubuntu-skylake: Florin Papa wrote me that the machine became unavailable in December 2016. * Yosemite ICC buildbot (intel-yosemite-icc): it was maintained by Zachary Ware and R. David Murray. Sadly, David lost the VM image to a disk crash :-( New ICC buildbots may come back later, wait & see ;-) * macOS Snow Leopard (murray-snowleopard): this old machine was stuck at boot for an unknown reason. "It's an old machine, and it is probably time to get rid of it." wrote R. David Murray :-) == Reduced failure rate == As usual, many race conditions were fixed in tests and in the code, to reduce the buildbot failure rate. I may list them in a blog post, later. == What's Next? == * Buildbot should be upgrade to buildbot 0.9: https://github.com/python/buildmaster-config/pull/12 * Zachary Ware plans to rewrite our buildbot configuration during the CPython sprint (Sept 4-9) * test_logging fails randomly on FreeBSD 10 with a warning related to threads (bpo-30830). I was trying to reproduce the bug since 2 months. I just identified to root bug! https://bugs.python.org/issue31233 "socketserver.ThreadingMixIn leaks running threads after server_close()". * The "Docs" buildbot (currently offline) may be dropped as well, https://github.com/python/buildmaster-config/pull/21 See also my previous buildbot report: https://haypo.github.io/python-buildbots-2017q2.html Victor
