thinker
- I have found content of script tags would be run before following content of the document arrive. It means CSS and other resources would not be handled for blocking by a long run script in a script tag. Interruptible script runner maybe helpful.
This Week Priorities
kanru
- Structured Clone (reduce OOM)
- Crash components
- MOZ_MUST_USE
- JS stack in crash report
thinker
- Network, focus on load resource earlier
- Improve task tracer (scriptable interface)
- idea: randomly insert guard pages
cervantes
- Study heap memory in minidump, experiment with previous crashes
- idea: guard pages for jemalloc arena
- e10s media crash, possibley gmp related
wcpan
- More MOZ_MUST_USE
- Fix Coverity discovered bugs
ting
- Fragmentation. Experiment on previous crash to see the virtual memory layout
- RelaseData() crash
gweng
- JavaScript GC slowness on GDoc
- Wait bailout result from QA
Incoming
- Sep: Many team members plan to take PTOs for the Mid-Autumn Festival.
