Is MSVS 2015 the only supported compiler for Python 3.5 on Windows? What's the other buildbot using MSVS 2015?
For a while I think the only buildbot was my 8.1 slave, but I believe at this point Jeremy may also have it on his 7 slave. The latest on my 7 slave is still 2010 (which is still working, sans recent test failures).
I'll answer my own question here. According to PCbuild/readme.txt:
This script will use the env.bat script to detect one of Visual Studio 2015, 2013, 2012, or 2010, any of which may be used to build Python, though only Visual Studio 2015 is officially supported.
I'll admit I'm puzzled by the wisdom of using unsupported compilers on buildbots. I guess it's a historical thing. But I gently suggest that we should either upgrade those buildbots to a supported compiler or remove them entirely. Definitely we should remove unsupported the two unsupported platforms from the buildbots--that's just crazy.
To be fair, VS 2015 hasn't been officially released yet. It only recently (as in a few weeks ago) reached RC stage. Given the size of installing it, and earlier uncertainty about upgrading during the pre-release cycle, plus some early issues with the build process, for my part I've opted to hold off with my older slaves until it hits release status, using only the 8.1 slave until then. (Arguably the current RC is supposed to be at most a minor update away from full release, so we're probably close)
Along the way it was concluded that XP just wasn't worth making work for the 3.5+ development, but the slave was still valuable for the 2.7 branch, so would be left around for now for that purpose. It is a bit misleading to still be trying to build the 3.x branch on it but I suspect eliminating the branch from that slave is just an oversight, or nobody with the proper access has had time yet.
