Track mib compilation artifacts #2709
Conversation
Turns out this didn't work! Now it does. The check of edge acted as a workaround that prevented clearing more files than necessary, but when multiple output artifacts existed, it over-deleted them, apparently. So now this is properly checked as a bit of logic and all tests keep passing.
This allows incremental builds with these files.

Specifically here, the artifact file was possibly deleted more than required when the previous implementation didn't match on the extension (we pass in [".beam"] for ArtifactExt, or for the MIB compiler, [".hrl", ".bin"]), but the .erl compiler used the on-disk build artifacts to re-fetch the compile opts as a fallback and likely hid the bug.
This might represent a perf gain?

@max-au this is code you had initially written, I don't know if you still care about that aspect of the workflow or if you've moved elsewhere tooling wise yet.

We didn't have any *.mib files or anything similar, so I guess I could never notice it. Change itself looks fine here, although it appears to be fragile enough to at least attempt a test...

Yeah the test is implicitly covered by the MIB test. Without that change, the compiler permanently kept deleting build artifacts' from the DAG and recompiling them, which failed the test case. I'll look at making a more explicit one though.

That was a good call, turns out there were dangling artifact vertices in the DAG as well (the files were deleted and the edge removed when the source went away, but not the artifact vertex). The new regression test covers that as well.

ugh, will fix the sorting issue with the windows paths by doing crappy naming schemes. |
This discovered a bug where dangling artifact files could be left in the DAG and bloat it over time. This was unlikely to be a real problem, but it's nice to be clean.

This has two parts:
