1243231 - Implement a taskcluster-based b2g hazard build

Status: RESOLVED FIXED

(Core :: JavaScript: GC, defect)

Description

[Steve Fink [:sfink] [:s:]]

The buildbot builds are all going away (see bug 1236835). The hazard build is orphaned. We need(ed) a new taskcluster-based hazard build. Except that b2g is tier 3 now, so we don't really. But I have this working, it is much simpler, and it will serve as a good base for a taskcluster browser hazard build.

The only issue with this is that it finds a hazard. :( But it's the same paramBuffer false positive that I battle with off and on.

Implement a taskcluster-based b2g hazard build

Terrence - can you review the portions of the shell script (build-mulet-haz-linux.sh, build.b2g, and the mulet-hazards mozconfig) that have to do with running the analysis? They're happily quite dull.

Greg, all of the job setup is for you. There are some strangenesses I inflicted on shared code, I'll comment on those sections.

I suppose I could have split this into two patches with an empty body for build-mulet-haz-linux.sh...

I removed --overwrite because it's deprecated, and I have another patch where I use this to cache tooltool checkouts (not just downloads; that's already cached). It helps with the development debug cycle because the rustc checkout takes quite a while. Probably, though, it'll need to be opt-in since it sticks a file into the checkout.

Anyway, for now this is just a removal of a deprecated option.

Attachment: Enable linux64-mulet-haz on main trees to take over from linux64-b2g-haz,

I split out enabling this on main trees, starting out with just having it on try, until I disabled the original b2g hazard job. That has now been done, though currently it's awaiting the next reconfigure, so it's time to push this portion too.
