Need To Know

(Release and system issues that may impact engineering this week.)

Notices/Schedule (lsblakk/sylvestre)

Next Merge: July 8, 2024 Next Release: July 9, 2024
Trains
Central: 129 Aurora: 54 Beta: 128 Release: 127


Build Changes (gps)

(Build changes of which engineers should be aware.)

RelEng (catlee)

(Repo, test, and other information for engineers from the release engineering team.)

Upcoming Outages/Upgrades

(System outages/upgrades and tree closures that impact engineering.)

Quality Programs

(An opportunity to hear about status with the various quality programs that do not have a formal team structure.)

OrangeFactor (ryanvm)

CritSmash (dbolter)

MemShrink (njn)

  • Jan de Mooij enabled optimized Latin1 strings in the JS engine. This saves over 4 MiB when starting Firefox and loading Gmail using a Latin1 locale. (And it's still a win on non-Latin1 locales and pages because they still use lots of Latin1 strings, identifiers, etc, and Firefox's own JS code is still written mostly in Latin1.) This also speeds up some string-intensive operations such as some regexp operations.
  • (BTW, this change is also a textbook example of how to break up a large change into lots of small, manageable pieces, which leads to faster reviews, clearer progress, and easier bisection of introduced defects. See the tracking bug for details.)
  • Lots of B2G 2.0 memory usage regressions have been getting fixed recently (e.g. here and here) involving too many people to list individually. Lots of great work between the MemShrink team and the Systems Front End team.

Stability (kairo/bsmedberg)

Team Stand-ups

(In <2 mins, what did your team accomplish last week, on what is your team working on this week, and on what, if anything, is your team blocked? No questions during the stand-ups. All questions should be asked during the roundtable.)
