Hot Bugs

(Important bugs for which we need to find owners or additional help. If known, please include suggested team or knowledge needed to advance the bug.)

Orange Factor
  • bug 906378 – Intermittent layout/style/test/test_transitions_per_property.html | application timed out after 330 seconds with no output
    • #1 orange, currently unowned
    • bug 859807 also tracks a similar timeout – (milan: dholbert is looking at this one, it may be just adjusting the timeout)

Roundtable

(Comments and questions that arise during the course of the meeting or otherwise do not have a section.)

  • (Read only) Mozilla provides a platform where (currently employees only) can host web sites and services, kinda like EC2. More info at https://mana.mozilla.org/wiki/display/websites/paas.allizom.org. Consider using it for hosting your next Mozilla-related side project because transitioning from this service to IT-managed service is relatively pain free.

<Read only beyond this point>

Quality Programs

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

MemShrink (njn)

  • Justin Lebar is leaving Mozilla.
    • Looking back, nobody has contributed more to MemShrink over the past two years.
    • Looking forward, Justin has been in charge of MemShrink on B2G (e.g. see the etherpad he was maintaining) and knows more about B2G memory consumption than anyone else. With plenty of memory-related problems remaining on B2G, this is a hole that desperately needs filling.
    • We have transition plans: khuey is going take over.

OrangeFactor (ryanvm)

  • Past week’s OrangeFactor: 5.34 (Previous Week: 6.99).
  • bug 686828 and “code -20” failures are top remaining issues on Fx24.
    • Bug 686828 needs an owner (see above).
    • smichaud has a libevent patch in bug 884471 that works around code -20 failures. Landed on inbound today hoping for eventual uplift to Aurora/Beta.
  • *32* intermittent failures fixed in the last week – List – Thanks!.

Stability (kairo/bsmedberg)

  • cross-team workweek was last week: still digesting action items and such, but:
    • Kicking off a “stability support” project to auto-fix stability issues if possible and help users recover if not.
    • Status of “the AMD crasher”: David Major has been thrown into the lion’s den, and can reproduce this intermittently on a QA computer, but no definitive answers yet.
    • bsmedberg is working on doing better crash and hang collection from B2G builds
    • If you haven’t seen the crash-stats API, check it out, see the brownbag video, or ask questions on tools.socorro.
    • gps is working on improving the quality of the crash data sent to FHR
  • gfritzsche is finishing up a patch in bug 853864 which will log and profile IPC messages, and is then going to work on making Java out-of-process again.
  • The AMD crasher hit FF 23 without any forewarning, so the current system of building two release candidates is being abandoned. We are seriously looking into sending the release candidate to the beta population (need to figure out some MAR signing details and test).

Roundtable

(Comments and questions that arise during the course of the meeting or otherwise do not have a section.)

e10s Update (billm/dvander)

<Read only beyond this point>

Friends of the Tree

There were lots of great changes by volunteers in Core and Toolkit during the past week. Thanks to all of these contributors for their passion and hard work!

Build Changes (gps)

(Build changes of which engineers should be aware.)

  • bug 904979 creates a divergence between default build options for local and official/release builds with the goal of making local builds faster at the expense of not being exactly like release builds.
  • Many users are experiencing issues loading mozconfigs or mozinfo.json, especially with mach mochitest commands. If you encounter an error, please file it under Core :: Build Config as a P1 and assign to gps@mozilla.com.
  • glandium and gps have been making many changes to make rules and tier traversal. Be on the lookout for oddities/regressions and report them immediately.
  • |mach build| records resource usage of builds bug 883209 – will roll out to automation once it has proved itself. bug 907297 is open for people to improve the HTML display.

Upcoming Outages/Upgrades

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

Key Issues

(Non team specific issues that impact engineering.)

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.)

Accessibility (dbolter)

  • Pico TTS landed in gonk about a week ago and the service to connect gonk to web speech API is coming soon.

Add-on SDK (dtownsend)

<Read Only>

The team did awesome work last week fixing a whole mess of intermittent test failures.

App Tools (dtownsend)

No update

Firefox Desktop (gavin/dolske)

  • Australis update: the team is making good progress on performance.

    • Markus Stange wrote what should be a useful tool: reflow/restyle/painting profiler: bug 902857
    • Perf team (avih, vladan) have been helping out, chasing down TART issues and doing some profiling

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

MemShrink (njn)

The stealthy introduction of e10s (via the thumbnails child process) exposed a bug in multi-process memory reporting, which has now been fixed. Nonetheless, the existing way of handling multiple processes is hacky and gross and needs to be improved.

OrangeFactor (ryanvm)

  • Past week’s OrangeFactor: 6.99 (Previous Week: 5.95). Talos issues and infra problems main cause of spike. Infra issues are ongoing.
  • Ongoing efforts to reduce intermittent failure rate on mozilla-beta (Fx24) in preparation for being the next ESR branch.
    • Please respond to needinfo requests to keep these bugs moving.
  • 25 intermittent failures fixed in the last week – List – Thanks!.
    • Shout out to the Jetpack team for cleaning up many flaky tests in the Addon SDK.

Stability (kairo/bsmedberg)

  • In Which Web browser crashes the most?, ZDNet says “The best browser, in terms of the fewest number of defects, is Firefox 22…” \o/
  • General crash data looks good.
  • 23.0.1 fixes two high-volume third-party crashes that we saw in 23.0 (one with an add-on called “RelevantKnowledge”, one with some Radeon cards/drivers).

Notices/Schedule (akeybl/lsblakk/bajaj)

  • 24.0b2 with QA, desktop will ship this afternoon

The Need To Know

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

Notices/Schedule (akeybl/lsblakk/bajaj)

  • Firefox multiple Betas in one week carries on, FF23.0b4 (Desktop) will ship this afternoon
  • Firefox 22 Post-Mortem was held this morning
    • There is no sign of a need for a .1 for this release
46 bugs (37 bugs last week) 48 bugs (93 bugs last week)
Unresolved Aurora 24 Trackers (non-security, not tracked for Beta) Unresolved Beta 23 Trackers (non-security)

Build Changes (gps)

(Build changes of which engineers should be aware.)

Upcoming Outages/Upgrades

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

6.5 hour tree closure planned for Saturday, July 13 from 1200 PDT to 1830 PDT. Master tracker is bug 889996.

Summary of work that will be done and the impact:

  • Failover of the new Bugzilla environment will be tested between data centers.
    • Impact: Bugzilla (bugs.mozilla.org) may experience brief interruptions in service during the window
  • Buildbot database failover will be tested.
    • Impact: trees will be closed, so no negative impact
  • http://build.mozilla.org will move to new releng web cluster
    • Impact: may experience a brief interruption in service to build.mozilla.org though none is expected; in addition the trees will be closed so there should be no impact to builds during this time
  • Database servers across the infrastructure will have their masters changed in preparation for upgrades
    • Impact: These failovers happen in a couple of seconds, some apps may fail queries during this time causing an HTTP 500 error or needing a client refresh
  • Backend load balancers in SCL3 will be upgraded from 1g to 10g network connectivity
    • Impact: some backend databases may experience a few seconds of service interruption, most of these services only impact developer/releng resources that will already be unavailable during the tree closure
  • RelEng firewalls changed to “deny all” for unknown internet traffic (has been allowed & logged).
    • Impact: No current tests will be affected (already whitelisted). New tests will be denied access to internet resources, developers will need to coordinate with sheriffs & releng prior to landing.
