Need To Know

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

Notices/Schedule (lmandel)

Next Merge: February 23, 2015		Next Release: February 24, 2015
Trains
Central: 38	Aurora: 37	Beta: 36	Release: 35

• Today is release day! Congratulations on releasing Firefox 35 and Firefox ESR 31.4!
• 36 Beta1 ships Thursday
  • MSE is enabled in beta1. Please test YouTube playback on Windows and file bugs.
• 37 Aurora updates are scheduled to be re-enabled on Friday
• 38 Nightly will be the next ESR. Get your refactorings or other major changes in while 38 is on m-c.

A note on branching:

• FXOS v2.2 update : Please note that has diverged from mainline gecko and is on its own b2g37 branch. mozilla-aurora (gecko 37) will continuously be merged to mozilla-b2g37_v2_2 . So, if you have a gecko bug that you are fixing on aurora and impacts b2g as well, you do not have to worry about requesting approval twice as the sheriff’s will auto-merge it for you.

Next Merge: January 12, 2015		Next Release: January 13, 2015
Trains
Central: 37	Aurora: 36	Beta: 35	Release: 34

• 35.0 Desktop RC builds with QA
• 35.0b10 mobile – need to figure out what’s happening with bug 1073554
• 31.4.esr builds with QA
• Next week we’ll be doing a throttling change where the plan (unless there are known issues in the wild) will be to enable updates at 100% on Friday Jan 16th (4 days earlier than current)

MemShrink (njn)

<Read Only>

DMD is now working reliably on Mac, and also seems to be working on Fennec. Follow the instructions and try it out!

Stability (kairo)

• bug 1088148 is a supposed a11y crash fix that triggered a huge spike in its own crash signature. This is 1/3 of current Nightly crashes!
• bug 1116825 was a significant plugin crash spike, but fix should just have landed.

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.)

Desktop Platform (bsmedberg)

1. What has your team done since last week that might impact others?

• bug 1110215: Disabled Flash protected mode on Beta as an experiment. See bug 1111791 for a report on the results.

Q1 plans: [1]

• Video/Flash fixup
• e10s
• telemetry/FHR unification
• update orphaning
• catastrophic memory usage

Electrolysis (e10s) (blassey)

• Known issues: https://wiki.mozilla.org/Electrolysis#What_to_Expect

• Given ~140 Aurora-blocking bugs and our fix rate, e10s will probably ride to Aurora 40 (and hold there for more testing).
  • Bug burndown chart: https://people.mozilla.org/~cpeterson/burndown/burndown.html?tracking-e10s=m2+,m3+,m4+,m5+,m6+
  • e10s release is TBD later this year, but likely won’t ride to Beta until Beta 42 or later.

• e10s will be disabled (bug 1117867) for this last week of Nightly 37 to shake out any non-e10s bugs.
• e10s will be reenabled (bug 1117934) next week for Nightly 38 testing.

GFX (milan)

<Read Only>

• Most of the team is back online this week. Catching up.
• Items for 37-B2G-Aurora landings are on track.

Layout (jet/dbaron)

<Read Only>

For Q1 priorities, see the “Current Plans” section here:

• https://wiki.mozilla.org/Platform/Roadmap#Layout

Media (mreavy)

<Read Only>

0. What are your team’s plans for Q1 that might impact others?

• Multistream and renegotiation support for WebRTC
• Hello front-end development transitioning from Platform to Firefox

1. What has your team done since last week that might impact others?

• Second phase of Hello/Loop about to hit release/35 (Rooms redesign)

2. What will your team do this week that might impact others?

• Expecting to land major webrtc upstream code update immediately after 37 uplifts
  • Already green on Win/Mac/Linux

Performance (vladan)

1. What has your team done since last week that might impact others?

a) bug 998863: Asynchronous initialization of plugins has landed

• It’s currently preffed *OFF* by default, please help us test it: set dom.ipc.plugins.asyncInit to true
  • There are stability problems with e10s at the moment, Aaron is working on fixing these issues
  • Mark any bug reports as blockers of bug 1116806

b) Many Telemetry measurements are biased by users who submit many short sessions (vs users with fewer, longer sessions). You can remove this bias by doing your analysis “per user” using the new clientID field:

• http://robertovitillo.com/2014/12/19/clientid-in-telemetry-submissions/
• http://nbviewer.ipython.org/gist/vitillo/6105522e83540a9a4d59

2. What will your team do this week that might impact others?

• bug 1021842: A-Team and Perf team are working on making the Talos regression detection formula more accurate
• We’re going to try to have devs make a decision (wontfix, will fix before branch date, etc) on each Talos regression within 2 weeks of the regression bug being filed

irc #planning Log From This Meeting

10:52 AM <KaiRo> lmandel: looks like I found the issue behind the gfx issues on beta, see https://bugzilla.mozilla.org/show_bug.cgi?id=1097321#c26
10:53 AM <KaiRo> and lsblakk ^^^
10:55 AM <lmandel> KaiRo: Good sleuthing.
10:56 AM <KaiRo> lmandel: luckily I just stumbled over bugmail of SoftVision verifying that bug that seems to have caused the issue ;-)
10:57 AM <KaiRo> and that got me thinking "hey, we did just land unblocking something that includes Intel stuff? wait a minute..." ;-)
11:00 AM <KaiRo> lsblakk: actually, 1) sheriffs/RyanVM can do a straight backout right away if we are sure enough, that doesn't even need Jeff, and 2) I'm actually reluctant to sign off 35.0b4 with this huge startup crash issue continued
11:00 AM <•lsblakk> ah, didn't see that it was a startup crash anywhere until now
11:00 AM <•lsblakk> in that case, i'm happy to take a backout and do a build 2
11:03 AM <overholt> cpeterson, did milan_ and I get disconnected?
11:03 AM <KaiRo> lsblakk: yes, took me a bit to realize as well, I'm definitely in favor of a build2 there.
11:04 AM <cpeterson> overholt: i don't see you guys on screen
11:04 AM <overholt> cpeterson, thanks. looks like a Vidyo crash. we're back.
11:04 AM <Pike> not just that the calendars are all upset, my head thinks it's wednesday, too
11:07 AM <RyanVM|sheriffduty> KaiRo: lsblakk: backing out now
11:07 AM <KaiRo> RyanVM|sheriffduty: thanks
11:10 AM <RyanVM|sheriffduty> jduell: CC me to that bug when you file it?
11:10 AM — RyanVM|sheriffduty wonders if that's the same underlying issue we have with other emulator test stability issues
11:11 AM <jduell> RyanVM|sheriffduty: will do
11:11 AM <RyanVM|sheriffduty> thanks
11:11 AM <jesup> jduell: sorry, we don't detect it directly: #if defined(MOZ_WIDGET_GONK) && defined(DEBUG) // B2G emulator debug is very, very slow and has problems dealing with realtime audio inputs
11:11 AM <jduell> jesup: ah. Ok, thanks
11:13 AM <jduell> jesup: hmm, this looks interesting... http://mxr.mozilla.org/mozilla-central/source/gfx/thebes/gfxAndroidPlatform.cpp#117

Electrolysis (e10s) (blassey)

• Please help test e10s in Nightly!
  • Known issues: https://wiki.mozilla.org/Electrolysis#What_to_Expect

GFX (milan)

• B2G: the follow up to 2.1 (“2.X”) looks to be based on Gecko 37…
  • Graphics plans are unchanged from 2.2 to 2.X
  • Graphics plans were based on Gecko 38
  • So… will likely keep the 38 time frame and uplift to B2G 37 branch past the trunk. Will figure it out by mid January when this becomes relevant.

JS (naveed)

• Work Week
  • Shumway load time is highest priority
  • 2015 Planning (more on this to come)

Layout (jet/dbaron)

<Read Only>

• Landed bug 1089417 – restyling fixes for CSS media queries

Media (mreavy)

<Read Only>

• 1. What has your team done since last week that might impact others?
  • Hello is in Release/34! Early reviews are generally good (and recognize the differences for privacy compared to say Skype).
  • Landed sdparta! bug 1091242 – (rewrite of the majority of webrtc signaling, other than the parsing).
    • Known regression bug 1109130 breaks < MSVC 2013 compiles; fix shortly
  • Lots of great discussions at #mozlandia
  • FoxEye presentation (echoes of roc’s older MediaStream Processing proposal)
  • Work moving forward towards multiple streams of a type and renegotiation
• 2. What will your team do this week that might impact others?
  • Starting work towards a webrtc.org update
  • More sdparta work

Performance (vladan)

1. What has your team done since last week that might impact others?

• bug 1107779, bug 1107782: Avi found that the “activeTicks” FHR measurement significantly over-reports Firefox usage time, because Firefox fires “user-interaction-active” notifications while the mouse cursor is positioned over the browser even when the user is away from the computer
  • Should we just land the fix, or is it important to maintain continuity with the current measurement (for monitoring for relative changes)?
  • The above bugs are unrelated to the big drop in activeTicks reported in bug 1096498
• Talos numbers for most E10s tests are available
  • we’re still converting some tests, e.g. tresize
  • there are serious regressions from E10S, e.g. WebGL is 4x worse on Windows
  • Joel Maher said he’ll write a blog post summarizing Talos regressions/improvements from E10S
• Spark is the new, much faster way of analyzing large amounts of Telemetry data:
  • http://robertovitillo.com/2014/11/29/a-telemetry-api-for-spark/
  • https://www.slideshare.net/RobertoAgostinoVitil/spark-meets-telemetry

2. What will your team do this week that might impact others?

• bug 998863: Almost ready to land asynchronous initialization of out-of-process plugins

3. Is anything slowing your team down or getting in their way?

• bug 998863: Need one more review for asynchronous initialization of out-of-process plugins

Shumway (tschneidereit)

• As part of the FlashKill initiative, the Shumway team’s Q1 goal is to whitelist Shumway for Facebook’s Flash Video Player:
  • https://wiki.mozilla.org/Shumway/Roadmap#FB1_Milestone
  • Facebook test videos: https://www.facebook.com/gopro/videos
• Working with JS team on JS startup performance and Media team on video buffering.

Roundtable

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

Touch input standardization update (mbrubeck)

• W3C Pointer Events going to Proposed Rec. Shipping in IE, portions shipping in Chrome, partially implemented in Gecko.

1. What has your team done since last week that might impact others?

• bug 1101193 – e10s has temporarily been disabled for this week, the last week of Nightly 36, to shake out any non-e10s regressions before the Nightly/Aurora 36 merge date.
• bug 972507 – BugzillaJS add-on now works with e10s
• bug 1058251 – “File > Save Page As” works with e10s
• bug 1008435 – Gecko Profiler now works with e10s

2. What will your team do this week that might impact others?

• e10s will be reenabled by default next week for Nightly 37.

Firefox Mobile (snorp/blassey/mfinkle)

• MP3 audio playback on Android L

Layout (jet/dbaron)

<Read Only>

1. What has your team done since last week that might impact others?

• Landed display:contents
• Bug 1074528 – Implement parsing/computing of inset()

2. What will your team do this week that might impact others?

• Portland!

Media (mreavy)

<Read Only>

• Fixes to Block & Cancel done and uplifted

• Rooms on Aurora should be enabled tonight

Necko (dougt/jduell)

• Looking into the HTTPS/TLS feature set of our new search partners: short answer is they’re behind Google on some issues.
• figured out why our patch fails on B2G emulator

Performance (vladan)

1. What has your team done since last week that might impact others?

• Firefox responsiveness metric:
  • We landed a Telemetry probe that measures delay in ms between the target and the actual handling time of the frame at refresh driver
    • http://mzl.la/1zRFtOP
• Looked at BHR data to determine how common are plugin hangs:
  • Preliminary data from one day on Nightly (not reliable!): https://etherpad.mozilla.org/tKgLhkkTVe
  • More reliable data from Aurora: http://robertovitillo.com/2014/11/25/clustering-firefox-hangs/
  • These numbers help set expectations for benefits of aklotz’s async plugin init patch & Shumway work

2. What will your team do this week that might impact others?

• Portland: Roberto will hold a tutorial on analyzing Telemetry data using Spark, a much faster way to do custom analyses of large amounts of Telemetry data
  • Date & location will be posted on m.d.platform
• bug 1076775: Working on removing jank from the new “Forget History button” feature

Roundtable

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

Need To Know

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

Notices/Schedule (lmandel)

Next Merge: November 28, 2014		Next Release: December 1, 2014
Trains
Central: 36	Aurora: 35	Beta: 34	Release: 33

• As announced on dev-planning, Firefox 34 will take an extra week before release
  • CHANGE IN RELEASE DATE: Dec 1/2, 2014
  • CHANGE IN MERGE DATE: Fri, Nov 28, 2014
  • No change to Firefox 35 release date

• Desktop 34 beta10 ships today
• Mobile 34 beta10 ships tomorrow
• FINAL BETA: Desktop/Mobile 34 beta11 gtb on Thursday

• Some release related work week sessions (e-mail lsblakk for details):
  • Detecting issues earlier in the cycle
  • Mitigation strategies for issues in field that don’t require a point release (think blocklist)
  • Release process/schedule discussion

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.)

CritSmash (dbolter)

• We’re doing well on criticals, not great otherwise.

MemShrink (njn)

<Read Only>

areweslimyet.com (AWSY) is broken due to e10s landing. Bug 1100253 is tracking this. There’s a big warning at the top of AWSY so that people don’t freak out too much.

Stability (kairo)

• Overall numbers look good again except for Nightly (and Android Aurora, which is coming back down after a MediaCodec fix).
  • Nightly issues are mostly e10s and GFX.
  • While there’s some things we probably want to investigate, no firefighting needs on any channels above Nightly atm!
• Long-term crash rate graphs are now available for Nightly and Aurora in addition to Beta and Release

• Help needed: bug 1093683 (Yosemite crash when saving files) is rising across channels, needs investigation, if on Apple side, we may need to communicate with them.

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.)

A*Team (jgriffin)

<Read Only>

–run-by-dir for mochitest-browser-chrome has landed! See bug 1057512. Three tests are currently disabled as a result, we’re working on finding owners and fixing them:

• bug 1096285
• bug 1097056
• bug 1100301

Accessibility (dbolter)

<Read Only>

• Eitan implemented bug 1069598 gesture quicknav (for Gaia)
• Trevor is ready for engineering help with our e10s a11y solution (will reach out)
• W3C land: possibility of element.getComputedRole is being discussed. Essentially this opens the door to accessibility-like DOM API. A downside is it will be a little too easy to instantiate our a11y engine (increases exploit attack surface), upsides include a11y innovation as well as a11y acid tests.

Electrolysis (e10s) (blassey)

• e10s is still enabled by default for Nightly users (except IME or a11y)
• bug 1089008 – Windows without gfx hardware acceleration will no longer automatically disable e10s
• bug 1066685 – Jetpack page-mod add-ons are now e10s compatible. This is big news for add-on compatibility.
• bug 980161 – Tracking Protection is now e10s compatible.
• bug 980161 – Shumway is now e10s compatible.
• bug 1047248 – Firebug version 3 (alpha) is now e10s compatible.
• bug 669200, bug 961361, bug 1098055 – Many plugin fixes for e10s compatibility.
• Screenshot of Gecko Profiler for e10s:
  • https://www.dropbox.com/s/uxsdu5f1sor5kd0/Screenshot%202014-11-17%2015.59.30.png?dl=0

• We may disable e10s on Nightly a few days before the Aurora merge date.

Firefox Mobile (snorp/blassey/mfinkle)

• Possible uplift of fixes (bug 1086693) and enabling MediaCodec backend on 34 now that we have some more time

GFX (milan)

• Desktop QA is maintaining a “Top 5” graphics bugs in Trello that we’re using to prioritize bug fixing. Very convenient.
• (Still ) chasing some blacklisting opportunities, mostly on AMD now.

Layout (jet/dbaron)

<Read Only>

• CSS properties “object-fit” & “object-position” have landed (impl: bug 624647, pref-enabled: bug 1099450)
• Should be enabled in tomorrow’s nightly, depending on inbound merge timing.

Media (mreavy)

<Read Only>

• Hello problems over the weekend caused by a Push server update
  • Push team figuring out what went wrong and why an update they didn’t intend got included
  • Seems stable now.
• Fighting a 20fps max issue in B2G 2.1 (regression likely due to bug 848954)
• Looking to update media/webrtc/trunk either late in 36 or early 37 (more likely) with code shared with Chrome 40
• Major rewrite of webrtc signaling about to land
  • Moving towards renegotiation and multiple streams
  • bwc++!

• Mac Support for MP4/h264/AAC switched off in beta and will not release in 34, expected to ship in 35. (bug 1068455‏ and bug 1070703)

Necko (dougt/jduell)

<Read Only>

• No update this week.

Roundtable

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

11:05 sydpolk: thx!
11:05 KaiRo: cpeterson: I guess you didn't reload, otherwise I would have done a very brief stability update
11:06 cpeterson: KaiRo: OK, we can jump back to you
11:06 KaiRo: cpeterson: ok, thanks
11:12 ctalbert: snorp: yay for that network link fix \o/
11:12 snorp: ctalbert: yeah seriously
11:12 snorp: ctalbert: bagder had a hell of a time landing it
11:13 KaiRo: milan_: other than getting more people to test Aurora, I don't know too much of what we could do better
11:14 lizzard: kaiRo: yeah, i think people with older computers may not be rushing to run Nightly
11:14 milan_: KaiRo: yeah, that's what I'm afraid of
11:14 milan_: we have webgl performance work coming up, and XP is a fairly large target, so it'll get interesting trying to do it without completely messing them up :)
11:15 KaiRo: milan_: of course, the amount of crashes that have been reported as OOM|small but weren't really OOM has not helped, but we finally should have fixed the largest issue with that
11:16 RyanVM|sheriffduty: snorp: I try ;)
11:16 snorp: RyanVM|sheriffduty: it found actual bugs!
11:16 snorp: testing works yay!
11:16 RyanVM|sheriffduty: our tests work! \m/
11:18 KaiRo: milan_: FWIW, you probably heard that we had reftests failing with OMTC off, I asked User Advocacy and it looks like they can confirm that users have been reporting more rendering issues last week as well, so that matches as well :)

Notices/Schedule (lmandel)

Next Merge: October 13, 2014		Next Release: October 14, 2014
Trains
Central: 35	Aurora: 34	Beta: 33	Release: 32

• Desktop 32.0.2 shipped last Thursday, included a fix for a start-up crash. Crash rates on release are now back to pre 29 levels. (That’s good.)
• 33 beta6 shipped today (desktop and mobile)
• only 3 betas left! We need your fixes. See the 33 tracked bugs list

OrangeFactor (ryanvm)

• Past week’s OrangeFactor: 4.17 (last week: 3.66).
• Android and B2G continue to dominate the top of the list. bug 906716 (B2G emulator “timed out after 1000 seconds of no output”) is #1 by a 2:1 margin.
• 17 intermittent failures fixed in the last week – List (16 the week prior) – Thanks!.
  • Thanks to Rail Aliiev for fixing bug 1047760, a long-running issue that affected all builds running on AWS.

MemShrink (njn)

• No update.

Stability (kairo)

<Read Only>

• Release crash rates have improved significantly since we released 32, almost back to levels we had before shipping 29
• Beta crash rates are still ~25% worse than they were right before we shipped 32, we’ll try to turn off OMTC and see if that makes up for the difference and which crash signatures this affects. In 34, we’ll have better tooling to analyze the crashes around OOM, which are a large chunk of those (somewhat expected as OMTC needs more memory).
• Desktop Nightly shows a number of e10s crashes. Please let us know if you see crashes of the whole browser at startup, as those are must-fix before enabling it.
• Android Beta needs someone in GFX to look into getting a patch for bug 1067018.
• Android Nightly needs someone to fix ImageLib bug 1069369, which accounts for >50% of our crashes there.

Media (mreavy)

<Read Only>

• Loop had a server failure over the weekend (database full). Making sure that doesn’t happen again
• Continuing to clean up OpenH264 and Screensharing issues for launch in 33
  • Set initial default allowed_domains for screensharing; created a process for adding people

• Alt-svc support almost done (bug 1003448)
• Network change detection very close–hoping it will land any day now 🙂 (bug 939318)
• Network predictor also getting close but probably won’t be done by end of Q3

Performance (vladan)

Fixes:

• bug 1038342: Firefox will now trigger a crash if shutdown hangs for more than a minute
  • “Are we shutting down yet” dashboard with signatures of shutdown hangs: http://yoric.github.io/are-we-shutting-down-yet-/
• bug 937306: Properly fixed our WaitMessage use on Windows. This should address user reports of pages not loading unless the user is moving the mouse. Needed for OMTC to be enabled on Windows for Firefox 33.
• bug 768802: Some good news: Flash 15 fixed a long-standing Flash bug that caused it to steal browser focus whenever the plugin process was launch or relaunched. This bug has plagued users for over 2 years, ever since Flash protected-mode was released.
• bug 918317: A C++ version of AsyncShutdown is now available
• bug 998863: Patch for fixing #1 cause of Firefox multi-second hangs (initialization of out-of-process plugins) will land soon. Please keep an eye out for plugin-related crashes over the next month. Contact aklotz or vladan if you spot any

Telemetry:

• bug 1045108: Unclaimed Telemetry probes will expire in Firefox 40! Please correct the expiration version yourself or comment in bug 1045108, or contact rvitillo or vladan. The unclaimed probes will stop collecting data!
• bug 1067372: We’re adding new meta fields to Histograms.json for better automated regression detection

Misc:

• Debugging Talos regressions has been tricky since GraphServer doesn’t show sub-test scores, DataZilla is broken (some requests time out persistently), and TreeHerder isn’t ready. As a stop-gap measure, Kyle Lahnakoski has exposed the detailed Talos data on his own machine bug 1063324:

Ongoing perf work:

• The performance of the new tab animation and the newtab page have regressed considerably since Australis first landed. Fx-team and Perf team will be meeting to work on this in MV on September 29th. See bug 1059558 etc.
• Work on improving performance of the Places system together with the fx-team bug 834545, bug 1043863, etc

irc #planning Log From This Meeting

11:02 cpeterson: https://wiki.mozilla.org/Platform/2014-09-16
11:05 bsmedberg: blassey: jimm: I'll be following up with you later about the e10s crashes
11:05 blassey: ok
11:06 lmandel: bsmedberg: I see readonly update about v2 sigs. Do you want to tell people what that means?
11:06 cpeterson: e10s content crashes are up about 100x since the e10s opt-in prompt
11:06 bsmedberg: lmandel: not really, do you think I need to?
11:06 lmandel: bsmedberg: Only if you think people will be impacted in their work.
11:07 lmandel: bsmedberg: We should probably call out when this is done so that people know.
11:07 KaiRo: hmm, do I only voip badly in those larger meetings? I didn't hear complaints in the smaller ones I'm usually in
11:07 bsmedberg: I think rstrong will be sending an email around to dev.platform when the current oranges/issues are solved before we actually flip things over
11:07 lmandel: KaiRo: You were fine in the channel meeting.
11:07 lmandel: bsmedberg: k
11:08 KaiRo: lmandel: ok, maybe the added traffic of more people on the meeting tips it over or so
11:09 KaiRo: btw, "Firefox is not starting now" seems to be a quite common issue with e10s
11:09 armenzg_mtg: cpeterson, I will mention it here
11:09 armenzg_mtg: I tried e10s on Linux Desktop nightly recently and it was a pretty awful experience
11:10 armenzg_mtg: enabling it by default even for one day will be pretty terrible for nightly testers
11:10 KaiRo: snorp: did you get a crash reporter at all for that non-starting thing with e10s?
11:10 snorp: KaiRo: yeah, standby, will paste
11:11 snorp: https://crash-stats.mozilla.com/report/index/c5ef1fca-fde0-44c8-95ef-680052140916
11:11 KaiRo: snorp: ok, good to know, startup crashes sound like the first thing we need to fix
11:11 snorp: yes.
11:11 armenzg_mtg: cpeterson, what is the preferred way to give feedback about e10s?
11:11 KaiRo: xpc::AddonWindowOrNull
11:11 KaiRo: sounds like fun with add-ons
11:12 cpeterson: armenzg_mtg: you can mention e10s problems in #e10s or just file a bug. Be sure to include the word "e10s" in your bug summary so our e10s triage queries will find it!
11:13 dveditz: armenzg: there's a link to file bugs at https://wiki.mozilla.org/Electrolysis#Contributing
11:13 armenzg: cpeterson, dveditz thank you gentlemen - I will dog food again
11:13 dveditz: also descriptions of known issues and links to known bugs for dupe finding
11:13 dveditz: on that page
11:13 dveditz: I mean a link to a query
11:14 KaiRo: snorp: can you file this one? sounds like this specific signature only exists today
11:14 snorp: KaiRo: https://bugzilla.mozilla.org/show_bug.cgi?id=1068163
11:14 cpeterson: armenzg: TBH, if you had e10s crash problems, you might want to wait a day before dogfooding again for some recent fixes to make their way to mozilla-central and then Nightly builds.
11:15 KaiRo: snorp: awesome, thanks. the signature seems to be all only today's build. fun.
11:15 snorp: KaiRo: yay
11:15 armenzg: cpeterson, I'm good with crashes - IIRC I was having responsiveness issues
11:15 cpeterson: armenzg: oh, that problem has not been fixed yet <:)
11:15 snorp: heh
11:15 snorp: cpeterson: what causes it
11:16 snorp: shouldn't it be *more* responsive
11:16 armenzg: cpeterson, k thanks
11:16 armenzg: snorp, in some cases :P
11:16 cpeterson: snorp: I don't know the cause, but there is likely some IPC bottleneck between parent and content process.
11:17 cpeterson: snorp: the browser should be more responsive (because its UI thread is not blocked on content as much), but all tabs run in the same process that can block each other.
