Build Changes (gps)
(Build changes of which engineers should be aware.)
- Add export MOZ_PSEUDO_DERECURSE=1 to your mozconfig for experimental faster building goodness. If you have 64 cores in your machine, the build system will scale up and use them all during C++ compilation. This will eventually be the default building mode. We’re working out bugs. This build mode is susceptible to race conditions. Please use it and report bugs.
- per-directory xpcshell test targets are being removed in bug 901990. Run individual tests via mach xpcshell-test or by using the top-level xpcshell-tests make target along with TEST_PATH.
- Run mach build-docs to produce in-tree documentation on the build system.
Upcoming Outages/Upgrades
(System outages/upgrades and tree closures that impact engineering.)
- IT may need 8?10? hour tree closure this weekend (SCL3 network downgrade). Still being investigated. Details in bug 917349. Watch newsgroups for info. (joduinn).
- Welcome to Balrog! New AUS.

- Daala – coding party next week in MV office (Sun, Sept 29th to Thurs, Oct 3rd) to move the new video codec forward. No DSP knowledge required. If interested, contact Maire (mreavy@mozilla.com). Details are developing here. We will feed you!
- WebRTC is focused on removing any unnecessary in-call audio delay or latency
- We just found bug 919215 which causes audio delay on MacOS when the internal mic and/or speaker are used.
- If you’re interested in helping us test and debug audio latency during a WebRTC call, please reach out to Maire (mreavy@mozilla.com) or Randell (rjesup@mozilla.com).

- bug 867757: You can now insert arbitrary annotations into Gecko Profiler profiles instead of just plain string markers. It can be used to track interesting things such as IO, memory usage or other timing information. Eventually this functionality will be extended to record stacks associated with interesting events that aren’t captured by profiler samples. Cleopatra UI improvements still to come.
Seceng (tanvi)
<Read Only>
- Users can now use the AES-GCM ciphersuites if they enable TLS 1.2. Bug 916226

- Jan will likely finish sync IDB first and then move on to async
- Ehsan looking for UX input on cursors/text selection on Firefox OS on dev-b2g
Quality Programs
(An opportunity to hear about status with the various quality programs that do not have a formal team structure.)
MemShrink (njn)
OrangeFactor (ryanvm)
- Past week’s OrangeFactor: 4.6 (Previous Week: 4.69).
- 24 intermittent failures fixed in the last week – List – Thanks!.
Stability (kairo/bsmedberg)
- Overall numbers look good, with the exception of Android 25.0b1, which is plagued by bug 918645 (fixed in b2).
- To enable tests and fuzzers to find stability and security issues more easily, we need our automated test suites to pass in sanitizers (ASan, etc.) – where are we on those efforts?
Roundtable
(Comments and questions that arise during the course of the meeting or otherwise do not have a section.)
