As seen on https://gitlab.com/git-vcs/git-ci/branches there are regressions since 2.19.0, e.g. we have hard compile errors on BSD now, and maybe AIX. I haven't dug into it.

I probably won't have the time for this myself before 2.21, but am sending this message in case others are interested. I don't expect these to be serious issues, just portability nits that'll either be fixed before 2.21, or alternatively by people packaging for those platforms. If they don't care enough to pursue it pro-actively I'm not very inclined to spend time on it myself...

Merge, but the useful bit of CI platforms basically devolves into
test_for(SHA1, params), with the hard part driving it so it's done
constantly, N branches are tested with smart notices of "XYZ broken in A
but not B" etc.

My impression is that you're *way* ahead with the Azure stuff for solving those hard parts. Is there any way we could ditch most of this ad-hoc GitLab CI setup I have on the GCC compile farm, and make it be driven by what you have, and at some point it would just do something like:

    ssh <some compile farm host> "compile-and-test.sh SHA1 <params>"

Then we could all display it in the same UI, and get feedback on "pu" topics before they land et.c
