SZEDER Gábor· Feb 7, 2019, 18:37 UTC · lore

Commit 2c8921db2b (travis-ci: build with the right compiler, 2019-01-17) started to use MAKEFLAGS to specify which compiler to use to build Git. A bit later, and in a different topic branch commit eaa62291ff (ci: inherit --jobs via MAKEFLAGS in run-build-and-tests, 2019-01-27) started to use MAKEFLAGS as well. Unfortunately, there is a semantic conflict between these two commits: both of them set MAKEFLAGS, and since the line adding CC from 2c8921db2b comes later in 'ci/lib.sh', it overwrites the number of parallel jobs added in eaa62291ff.

Consequently, since both commits have been merged all our CI jobs have been building Git, building its documentation, and applying semantic patches sequentially, making all build jobs a bit slower. Running the test suite is unaffected, because the number of test jobs comes from GIT_PROVE_OPTS.

Append to MAKEFLAGS when setting the compiler to use, to ensure that the number of parallel jobs to use is preserved.

Wouldn't all other hits of "MAKEFLAGS=" in ci/lib.sh also want the same treatment, though? We know that "if travis to this, otherwise if Asure, do that" is the first block to muck with MAKEFLAGS in the script, but a new assignment before that block can be added in the future and cause a similar issue unless we do so.

Of course, at some point we do want to say "we do not want to inherit it from the outside environment", but then such an assignment of empty value should be done at the very beginning with a comment, not with "this happens to be the first one to set, so let's not append but assign to clear any previous value", I would think.

Since this is intended to be run in a CI setting, there is not a whole lot of opportunity to set `MAKEFLAGS` outside of the script. And if there is, that might open a rabbit hole when debugging issues that somehow in the end turn out to come from a hard-coded `MAKEFLAGS` somewhere in the CI system.

So I'd rather clear `MAKEFLAGS` at the beginning (i.e. where you `export MAKEFLAGS`, I'd simply append a `=`).

Ciao, Dscho

I meant to clear it at the beginning, where I "export MAKEFLAGS=". Did your MUA ate the equal sign at the end, mistaking it with part of text/plain; format=flawed or something?

[PATCH] ci: clear and mark MAKEFLAGS exported just once

Clearing it once upfront, and turning all the assignment into appending, would future-proof the code even more, to prevent mistakes the previous one fixed from happening again.

Also, mark the variable exported just once at the beginning. There is no point in marking it exported repeatedly.

Don't be. Mistakes happen and watching stupid mistakes for each other is part of the teamwork I very much appreciate.

Will apply on top of Szeder's fix.  Thanks.
