ci: replace macOS 10.15 with macOS 11 in CI pipelines

striezel commented 2 years ago

Description

GitHub started the deprecation process for macOS 10.15 runners on 2022-05-31, and macOS 10.15 will be completely unsupported by 2022-08-30 (if things proceed as planned). That is, in less than a month macOS builds would fail permanently, so the corresponding jobs are moved to macOS 11.

References

This issue already hit us during the build for PR #716, because at that time there was a scheduled brownout for macOS 10.15 builds to raise awareness of the upcoming removal. It certainly worked. :D

See https://github.com/actions/runner-images/issues/5583 for more information on the removal of the macOS 10.15 images.

Tasklist

[ ] Ensure all CI builds pass
[ ] Review and approve

On second thought, it might also be worth to consider the removal of Azure builds altogether. As things are now, AzP are used for builds with GCC 6 and GCC 8 on Linux and with Xcode 13(?) on macOS 11. However, GCC 6 and 8 are also covered by the GitHub Actions workflow, and macOS builds with Xcode are covered by GHA, too. So there seems to be no benefit to keeping the AzP stuff, as far as toolset coverage is concerned. Or am I missing something? So I could update this PR to remove the Azure stuff, if that is acceptable. Any thoughts on that?

Just updated this PR to only replace the macOS image on GHA. New macOS passed on GHA, but it failed on Azure.

So I will probably add another PR that will remove Azure builds.

Even the old macOS version failed on Azure: https://dev.azure.com/boostorg/gil/_build/results?buildId=2042&view=logs&jobId=428b2f5c-d4ea-5628-f40b-db0b1f2cd10b&j=428b2f5c-d4ea-5628-f40b-db0b1f2cd10b&t=a1e26ec1-1cd6-52b3-5716-ab36bddef14c

macOS 11 failed with a similar error, too: https://dev.azure.com/boostorg/gil/_build/results?buildId=2041&view=logs&j=dbffb207-18be-561b-b0ae-80a806713608&t=c389dadf-49bf-5055-b7a5-f2217ec3ecf5

Yes, I think it's desirable to clean this up. Originally (or AFAIR), the AzP builds were added to build using our contributor-oriented CMake configuration.

However, as we have planned to clean the CI up, indeed, we should strive for usable bare minimum first.

Alright. I just pushed another commit that removes the Azure builds.
