There's a better fix available upstream, can we use that? bazelbuild/bazel#20587

Yes, saw that and I'll update the PR.

[avdv]

PTAL, I have incorporated the patch from bazelbuild/bazel#20612 and added a regression test adapted from #262152

[uri-canva]

Looks like it's broken on darwin, not sure if it's preexisting or caused by the PR:

It's the execlog parser though, not bazel itself, so maybe we can just stop building it.

👍 I added a commit which skips this step on darwin.

[uri-canva]

Doesn't seem to have worked, though I don't know why.

[uri-canva]

Oh no I see, the build of the parser is skipped, but then the install fails since it can't find the parser.

[uri-canva]

Back to you, sorry.

[avdv]

Back to you, sorry.

My bad. Seems like I fixed it this time, builds and tests are green on x86_64-darwin.

[avdv]

@uri-canva could you have a look again, please?

[avdv]

closing, superseded by #283480

[uri-canva]

Apologies I'm not very active these days, will look at #283480.
