Moving Python.org to Buildbot 9 + Python 3
by Craig Rodrigues 13 Oct '17

In the past two years, I've put a lot of effort into porting the following to Python 3: Twisted: https://www.slideshare.net/CraigRodrigues1/the-onward- journey-porting-twisted-to-python-3 Buildbot: https://github.com/buildbot/buildbot/pulls?utf8=%E2%9C%93& q=is%3Aclosed%20is%3Apr%20author%3Arodrigc%20 I would like to help Python.org move to Buildbot 9 + Python 3 for the following reasons: (1) Python.org currently uses Buildbot 0.8.14. This branch of buildbot is not under active development and is not being ported to Python 3. (2) The current version of Buildbot (0.9.11) is on the main branch which is actively maintained. This branch has been ported to Python 3. (3) Buildbot 0.8.14 is not actively being maintained. (4) Buildbot 0.9.x is actively receiving updates for new features such as Docker support, and support for Hyper.sh. A while back, I worked with Zachary Ware, who set up a proof of concept of running Buildbot 9 on Python.org. Zachary set this up: https://buildbot.python.org/test/ That is an instance running Buildbot 9, using Python 3.4.3 and Twisted 17.5.0. This is only a proof of concept, and is not actively being used or worked on. What are the next steps to completely convert Python.org to use Buildbot 9? Who can help with this? -- Craig

Linux buildbots with the vm_socket.h kernel header?
by Nick Coghlan 08 Sep '17

Hi folks, https://bugs.python.org/issue27584 is an RFE to add AF_VSOCK support to the socket module at least when the appropriate Linux system headers are available. https://github.com/python/cpython/pull/2489 aims to implement that RFE, but the config check is failing in pre-merge CI - the required kernel header isn't being found. We think that's just because Ubuntu 14.04 is too old to have the required header, and even though recent versions of RHEL/CentOS at least nominally have the kernel module available, we're not sure the required header is actually going to be present there either (it definitely isn't there in the CentOS 7.3.1611 docker image, and RHEL 7.4 is currently still in beta, so even if it does include the necessary header, we definitely aren't running it on any of our current buildbots) So my question is: are any of our current buildbots running sufficiently recent Linux distros that they actually have this header? If not, it would probably make sense to wait for at least one of them to be updated before we accept the change. Cheers, Nick. -- Nick Coghlan | ncoghlan(a)gmail.com | Brisbane, Australia

OpenSSL versions on builders
by Zachary Ware 04 Sep '17

Hi folks, Since OpenSSL 1.0.1 was EOL'd at the end of 2016, we're looking into whether we can drop support for OpenSSL 1.0.1 and earlier in Python 3.7. However, it looks like many of our builders are still using as far back as 1.0.1e. If you would, please check to make sure your builders are using the latest OpenSSL available from your distributor and let us know if it is not at least 1.0.2 so we can gauge how to proceed. Thanks, -- Zach
