Hello folks, CentOS Stream 9 buildbots have been added to the fleet for the x86_64, ppc64le and aarch64 architectures. Hope they serve the CI well :) https://github.com/python/buildmaster-config/commit/8fbb7492d4509df074750bc… -- Regards, Charalampos Stratakis Senior Software Engineer Python Maintenance Team, Red Hat

Adding Emscripten/NodeJS buildbot
by Ethan Smith 18 Jan '22

Hi! I'm reposting this because it seems to have been eaten by the moderation filter because I subscribed incorrectly and Mailman thought I wasn't a member of the list (sorry mailing list admins!). I am working with a small group of people to port CPython to Emscripten (and maybe eventually WASI). I currently have a repo here where we run a build against CPython main branch nightly https://github.com/ethanhs/python-wasm, but I think it is time to set up a buildbot for Emscripten. I am able to run the CPython test suite under nodejs with the proper environment set up, however several tests do fail due to issues with musl or in Emscripten (or in Python too, of course). https://gist.github.com/tiran/8d6b1e038206c2431daceec0768156d4 I have set up a VM on a server I run with 4 cores and 4GB of memory (the docs note the large memory tests require more than 512MB, but don't say how much the large memory tests take). Just to make sure I understand the process, since Emscripten is unlike the other builders in that it uses a custom toolchain, it looks like I will need to modify the buildbot code to add an EmscriptenBuild? How does development on the buildmaster work? Is there any way to easily test it locally? Also any suggestions on how to handle cross compiling in the configuration? We need a second build for freezing modules. Thanks for any guidance you can provide! Best, Ethan Smith

How does that work? Do I work on the code after getting a password and buildername? Also any suggestions on how to handle cross compiling in the configuration?
