TEAM UPDATES

(Alphabetical order)

Gaia Architecture Work

• Telemetry library
• Web app bridge (threads.js)

   - Stuck trying to identify why postMessage/BroadcastChannel is slow during startup.
   - Help needed with profiling Gaia apps please! :)
     - Tried B2G/profile.sh with pvt-eng build but fails
     - Trying to build B2G manually with MOZ_PROFILING=1, currently in VM world of pain.

• Service workers

   - Tried different ways to communicate with SW, so far we realised that the best method is using http verbs, since they wake up the sw if it's dead.
   - Make some test to try the different caches system, in this case we tried successfully the custom cache.
   - Working on bugs and improvements on the library.
   - app:// protocol supported now in SW, but we found some bugs.
   - about:sw on settings app

• SMS app conversion: will send a mail later today
• Music app conversion
• Contacts app conversion (prototype)

   - Moving views from Contacts App, now we can switch from one set of views to the other using a common service exposed in Threads.js! [1]. This will be useful when applying CustomCache.
   - This week we will be adding RenderCache (SW) to our prototype [2]
