Details
I am mentoring a bug that involves replacing an MFBT header with a standard header across the Gecko codebase (bug 1434710). The Try server is showing me that SpiderMonkey builds are failing with an error that was not present in a local Gecko build. The errors shown in the Treeherder failure summary are: TEST-UNEXPECTED-FAIL | check_spidermonkey_style.py | actual output does not match expected output; diff is above. TEST-UNEXPECTED-FAIL | check_spidermonkey_style.py | Hint: If the problem is that you renamed a header, and many #includes are no longer in alphabetical order, commit your work and then try `check_spidermonkey_style.py --fixup`. You need to commit first because --fixup modifies your files in place. I tried running `check_spidermonkey_style.py --fixup` as suggested. The first thing I noticed is that there is no check_spidermonkey_style.py file in the root of the m-c source tree. It's located in the 'config' subdirectory. So next I tried running `config/check_spidermonkey_style.py --fixup`. I got: -bash: config/check_spidermonkey_style.py: Permission denied It seems the file is not marked as executable, as is therefore intended to be run via 'python'. Third attempt: $ python ./config/check_spidermonkey_style.py --fixup Traceback (most recent call last): File "./config/check_spidermonkey_style.py", line 45, in <module> from mozversioncontrol import get_repository_from_env ImportError: No module named mozversioncontrol I don't know what's causing this error or how to fix it, or even where to look to find that out. I think we could make the experience better for a developer faced an error like this.

Correction: it's not only SpiderMonkey builds that are failing with this error, but also regular Linux builds. Which makes me wonder why I am not getting the error in my local Linux build.

The style checker doesn't run in local builds because it "takes too long". Or at least, when I added it to the regular build process awhile back people complained about it taking too long and it got undone. I continue to think this is Dumb. The messages here could be better, for sure. I'll leave this open/alone for that and comment on the original bug about how to fix, without having to block on this getting better.

(Note, I've already figured out how to fix the error in the original bug. While I haven't been able to get check_spidermonkey_style.py to run, I looked at the full error in the automation run's raw log, and made the change manually. It was just a header order issue.)

The expected way to run the style checker is to run make check-style inside an objdir, either of JS shell or all of Mozilla, I think. This too could be better explained in the error messages.

It also doesn't accept the --fixup option, so I still don't know how to invoke the checker with the --fixup option. In any case, it would be nice if there was a mach wrapper for this.

IIRC it runs the style checker pretty early on so you don't have to wait too long (after jsapi-tests but before the much slower jit-tests and jstests).
