I pushed my supposed fix yesterday morning, as I emailed out the "Fixed, hopefully" note.
Of course, I now see that it wasn't a full fix.
This is all most assuredly my fault. However, I also feel that elements of the infrastructure failed me somewhat, making this error easier for me to commit:
- Travis has not picked up on these errors.
- Harbormaster has seemed unreliable, finding spurious compile-time errors sometimes, and sometimes just failing to test code that it sees. For example, when I pushed Diff 1901 to D546, Harbormaster never even attempted. Also, when I pushed my "fix", commit 3ec9391711, Harbormaster also skipped, as viewable here: https://phabricator.haskell.org/diffusion/GHC/
So, after pushing yesterday morning, I didn't get any email from Harbormaster saying that it failed, so I thought my fix was indeed a fix. Because my local build was a devel2 build (and that I had only about 20 minutes to work), I was unable to test locally -- all I could tell is that my fix lowered the numbers (as verified by ghcspeed).
Having a weekend full of plans, there wasn't really any opportunity for me to do the work necessary to figure out what's going on. It will be first on my docket tomorrow.
I suppose one lesson here is that I shouldn't push anything at all non-trivial on a Friday afternoon. But I also hope we can either improve the infrastructure (of course, it's *much* better than it was months ago!) or have realistic expectations of what we can expect from the infrastructure (e.g., trust Harbormaster/Travis when seeking feedback, but always validate locally before actually pushing to master).
