@mstorsjo Could you take a look here? I've tried a bunch of stuff, but couldn't really get things to run properly. |
Sure, I can try to set this up. I have tested running libcxx tests on Windows GitHub Actions runners before, and got it working before (for a subset of configs, not using the libcxx |
I got it working for all of our Windows CI configs. See the two topmost commits at https://github.com/mstorsjo/llvm-project/commits/libcxx-gh-win-runners. The one setting up the actions stuff is quite straightforward. The other one fixes a seriously annoying issue in how CMake picks python, please read the commit message thoroughly. Also, running the libcxx tests on Github runners used to be quite annoying as they used to be quite limited (2 cores, 8 GB memory only), so earlier, I've had to set |

When we're ready to merge this, we should add needs: [ stage1, stage2, stage3 ] to only trigger the Windows CI if the other stages are happy.
There was a problem hiding this comment.
I'd rather only wait for stage1, since the GitHub-provided agents are quite slow. I think it's quite unlikely that we'll actually hit resource limits, since we have up to 60 concurrent agents available, i.e. more than 7 libc++ patches uploaded in an hour that don't fail on stage1. We can still put that higher later if we do hit limitations at some point.

Can you limit the total number of jobs to 40? We need to have some spare capacity for running some of the other jobs, like the PR labeler, code_formatter, etc. We may be able to bump it higher in the future, but I think 40 is a good start. |
I thought this was possible, but I haven't found a way to actually limit the number of jobs. I f you know how to implement this then that is great, but otherwise do you have an estimate of the number of concurrent machines you will need to handle the peak load? |
Hm, yeah. I thought it could be done with |

FYI - ideally we wouldn't need to have things like this in the main CMakeLists.txt.
Ideally we'd set it in the CI environment, as we happen to need it there due to how the Github runners are set up. It is possible to pass this on the CMake command line, I think, like -DPython3_FIND_REGISTRY=LAST, but the run-buildbot script doesn't support passing extra command line parameters to cmake.
On the other hand - this doesn't really hurt either; the cmake default behaviour is really really surprising here, and this makes it less surprising. It makes things a little inconsistent to keep setting this in the runtimes/CMakeLists.txt only - I wonder if we could set it e.g. cmake/Modules/CMakePolicy.cmake as a sort of project-wide default policy?
Anyway, just venting my thoughts on the matter - no urgent action needed.
