Project Updates

Australis

• Notable bugs fixed within the past week:
  • bug 881905 – Can’t drag Facebook button to main customization palette
  • bug 881905 – Make Downloads Panel anchor to the chevron if it is overflowed
  • bug 885086 – Overflow panel looks kinda wild when wide items get in there

  • bug 919541 – Consider not animating the opacity for Australis tabs
    • [from mconley] This seemed to cut our total regression by over 37.9% on XP. We started with a total TART regression in the neighbourhood of 6.35%, and ended up with a total TART regression of 3.94%
    • Check out our perf regression now
  • bug 885579 – Narrow widgets dropped on a wide widget should place the narrow widget above the wide widget

• Landing blockers (outside of perf tracking):
  • bug 874674 – Clean up menu panel icons for Linux GTK theme
  • bug 875479 – Australis toolbar buttons for Linux
  • bug 916953 – Bookmarks button in overflow panel looks broken

• Net bug changes
  • P1: -4 (was 10, now 6)
  • P2: -2 (was 17, now 15)

• Performance
  • Vladan is investigating whether our ts_paint regression even exists anymore, or if we’re just seeing measurement noise.
  • avih is trying to get us more accurate TART measurements for OS X
  • mconley is trying to find out why the URL bar merge slowed us down, and trying various experiments to speed us back up.
  • Current investigations:
    • bug 917795 – Find out why UX branch got better on TART between 1cbed63f3eea and 401c71c3732d
    • bug 916859 – Find out why UX branch regressed on TART at merge changeset c375e7bc34b3

Friends of the Firefox team

Give a shoutout/thanks to people for helping fix and test bugs.

• Luís Miguel (aka Quicksaver) for reviewing, testing and providing feedback on all the findbar bugs that we’ve been working on the past couple of months!

Project Updates

Australis

• We’ve backfilled the TART performance data for Windows XP going back to about mid-April, and dumped it into Datazilla (thanks jmaher!).
  • The graphs paint a pretty interesting tale. Green is m-c, purple is UX. Each graph that you’re looking at is one of the subtests for TART. These graphs just came in, so we’re still verifying their accuracy.
• We’ve identified a m-c merge changeset that caused a regression across the board for UX, but didn’t seem to affect m-c. See bug 916859. Now the challenge is to determine *which* changeset in that merge caused the problem. Mike is going to chat with graphics and layout to see if they can point out any obvious culprits to try backing out. Failing that, manual bisection – which is going to be a real trick, since we’ll need to merge from UX every time.

• Development finished
• Landing features for the first Aurora build

Next:

• Notifications + Larry Menu cross-over
  • Boriss and Larissa reviewed notifications spec and redesigned Larry Menu overlap, and how some notifications can be hidden in the permissions area of the proposed Larry Menu
  • next iteration of the notifications spec coming, sorry it’s taking so long!

• Larissa has moved teams to the Strategy and Insights team (aww and yay)
  • but don’t worry, she’ll still be coming to these meetings and will continue to work on Firefox features!

• Talkilla
  • What the hell is this? We’re working on interesting applications of WebRTC in Firefox. In particular, two use cases:
    • Accountless, anonymous, peer-to-peer communication (video, chat, audio), possibly expanding into screen-sharing later.
    • With-accounts, allowing users to bring in contacts, mobile phones, etc
  • Out-of-date wiki – https://wiki.mozilla.org/Talkilla – will be fixed soon

Project Updates

Australis

• TART performance
  • We’re bisecting UX like crazy. It’s a little tricky because there seems to be some noise in the measurements as we go, and we’re a little wary that the total regression is the sum of many small ones…but there is at least one changeset range where there’s been a pretty substantial regression, and we’re peeling into that.
  • MattN has noted that, at least locally, SVG clip-paths are pretty expensive on his XP machine, and removing them saw a 12% performance improvement compared to having the clip-paths. We’re going to pursue Graphics on the possibility of caching clip-paths in bug 914617.
  • Vladan has found a solution to our XP pseudostack problem – one simply needs to copy a more recent version of dbghelp.dll (he tested with DLL version 6.12.2.633) into the firefox directory. Once we’ve confirmed on a few other machines, we’ll update MDN (and possibly pursue getting that DLL put on all of the talos slaves)
• General
  • We fixed a bunch of P1 bugs and elevated some other bugs to P1. Net bug reduction!
  • We struggled with broken tests/builds for half the week, hence a somewhat shabby list – now fixed though, and full steam ahead!

Downloads API

• Significant reduction in the Slow SQL queries since landed in Nightly
• Plan to remove the preference that disables the new code in Firefox for Desktop
• Active outreach to extension developers this week before the Aurora migration
• Planned API changes, and final review before the Aurora migration
• Feedback on known temporary regressions and also on positive additions
• Tremendous progress this week on 10 of 12 bugs tracking release

  The 2 remaining bugs are the DownloadTaskbar front-end and one minor regression to investigate

• Conversation with Sam Foster of the Metro Firefox team to evaluate switching to the new API
• Upcoming firefox-dev post

Thumbnailing

Foreground thumbnailing

• addressed by patch in bug 906615 (below): bug 809051 – Limit how often we thumbnail the page using the foreground service

Background thumbnailing

• landed: bug 875986 – BackgroundPageThumbs should be able to capture private thumbnails while private browsing is active
• landed: bug 909218 – Allow a docShell to have default load flags that will be applied to every request made from it.
• landed: bug 912763 – Disable background thumbnails on Beta
• landed: bug 910563 – gracefully handle remote process crashing
• landed: bug 906713 – Intermittent browser_thumbnails_background.js | Thumb browser should exist immediately after capture.
• landed: bug 903299 – Modal dialog / prompt failures when running browser_thumbnails_background.js
• should be fixed by bug 875986‘s landing: bug 899064 – Profiler won’t turn on because it thinks I’m in private browsing mode [due to background thumbnails]
• new patch for review: bug 906615 – Background thumbnail service shouldn’t overwrite existing thumbnails, or at least foreground thumbnails should be preferred
• waiting on review: bug 910036 – about:newtab shouldn’t load thumbnails in background when hidden by preloader
• patch for review: bug 913171 – Intermittent browser_thumbnails_background.js | Captured URL should be currently expected URL

SessionStore

(Steven and I are unfortunately unable to attend the meeting today. Feel free to read this out loud or just read it on your own 🙂

• SessionStore is affected by a possible data loss due to ChromeWorkers being aborted on shutdown, patches under way to fix this (bug 913899).
• The recent session cookie refactorings introduced a regression for huge sessions with lots of (nested) history entries, patches waiting for review (bug 912717).
• Telemetry for TabStateCache landed (bug 896545) and shows that our cache hit rates are great.
• We’re working on tests for the TabStateCache (bug 911115).
• Global Value API has been backed out to fix regressions before landing again (bug 899213).
• With nsIAppStartup.willRestart and .wasRestarted in the making (bug 911146) we will be able to get rid of some more ugly code (bug 914062).
• Missing tests are the last thing blocking us from landing the first async data collection patches (bug 894595).

Places API asyncification

• Raymond has posted most of the patches needed for the bookmarks backups improvements. Mak going to review them by the end of the week, then will go through the goal target and file any missing bugs to complete the project.
• Mano is working towards a solution to a problem with guids and the new async transactions, as well as on a regression fix due to recent related changes. Patches are in the bugs and Mak going to review them.
• Mak currently working on regression fixes for issues introduced by automatic batches in Places views.

Social API

• pref on blocked by e10s issues
• looking at austrails
• spending week tracking down any issues that should be tweaked before uplift
• next week in SF

e10s

• bug 899348 Tab crashed page
• bug 913155 Submit crash report from tab crashed
• Many bug fixes work

UX Updates

lco

• I’m back! I missed you guys 🙂
• Thailand was *awesome*. Updates soon about what we found.
  • One teaser: Searching for information was the most important use for the browser. People equated a “fast and easy” browser as one that got them to a search box the fastest; Users said that Chrome was the browser of choice because they didn’t have to go to “google.com” to perform a search. On Android, many people used the Google search widget to access the Internet, not the browser.

• Focusing on tab animation tests now. The TART test is now feeding numbers into Datazilla, and we’ve got an idea of the target we’re trying to hit here.
• While one or two of us get our heads wrapped around tab animation performance, some devs are shifting from performance back to behavioural bug fixing. Please watch for regressions on UX, and file bugs!
• Notable bugs fixed within the last week:
  • bug 880388 – Show an accurate preview of the size of a widget when dragging a widget over a target in customization mode
  • bug 896887 – Hide the menu bar by default on Linux
  • bug 865916 – Create a Character Encoding widget and subview

General Topics

• People:TRIBE
• Removal of “Enable JavaScript” and “Load images automatically” in Firefox 23
  • For me, this has rendered this version of Firefox unusable, and my only alternative was to uninstall it and reinstall 22. I hope that these option checkboxes will be restored in Firefox 24.

Friends of the Firefox team

Give a shoutout/thanks to people for helping fix and test bugs.

• brinks7 who (although ~2.5 years ago) provided a great STR that helped _a lot_ with finally fixing bug 637020. [ttaubert]
• onemen.one for providing lots of helpful comments on recent SessionStore improvements and regressions. [ttaubert]

Project Updates

Australis

• Still fighting performance regressions. Not much to say beyond that. Pushing as hard as we can.
• Trying to get more help from the Graphics and Layout teams.

Downloads API

• It is a matter of days before switching the browser.download.useJSTransfer preference
• Will wait before posting the bi-weekly update to firefox-dev

Thumbnailing

• Lots of open bugs, many due to IPC. Exposed lots of problems in the browser’s e10s implementation, such as it is so far.
• See dependency tree.
• Apparently background thumbnails break AdBlockPlus and possibly other add-ons, for some definition of “break.” See bug 904341.

SessionStore

• Lots of smaller code cleanups that help us understand more details and maintain SessionStore.
• Work on reducing SessionStore impact when creating tabs to restore a session (bug 900803 and bug 901137) in progress.
• We are working on introducing an API to store data per session bug 899213, just like Scratchpad does.
• Fixed a very long-standing data loss issue bug 637020 that could make us lose whole windows when crashing at or shortly after startup.
• Getting closer to move first parts of the data collection to content scripts, bug 894595, bug 903388, and bug 904003.

Social API

• met with potential new providers
• w3c social standards workshop wrapped up
• refocus on getting to review stage for better multi provider support

e10s

• Landed:
  • bug 516753 context area menu (using CPOWs)
  • bug 897062 middle click support (for links/scroll)
  • bug 902695 openURIInFrame (support for opening in new window)
  • bug 870625 Make add-on installation work
• bug 899222 About:home backed out
• Three bugs of interest
  • bug 897060 – Dropdown menus (<select>)
  • bug 899648 – alert()/prompt()
  • bug 896787 – URL bar gets cleared after opening a tab

UX Updates

lco

• Design Patterns proposal for Notifications + application to Mixed Content / CtP (hooray, not too much backlash!)
  • http://people.mozilla.com/~lco/Permissions%20UI/130806%20design%20patterns-permissions%20UI.pdf
  • Darrin is working on some animation prototypes so that we can test our discoverability assumptions
  • Once we’ve gotten some degree of confidence in the patterns, I’ll file bugs for Mixed Content and CtP
  • what’s the next step in moving this forward?

• Encouraging more design contributors
  • what would be useful for engineers?
• Browser hanging up
  • Working on it
  • I am not saying I usually have 23 tabs open (right now there are only 21), but this time the hang up was because the popup box saying do you want to shut down the plug in was hidden (shouldn’t that be top level, and what happens if two windows want to be top level?). I have to say that I yearn for the old days when I could just use the lean and mean Opera that never hung up ever. This was probably over 5 years ago now. And I know it is almost useless for me to even be complaining about hang ups when I am using Windows (7?), instead of just switching to Linux…

• Now working on switching the transactions to use GUIDs so that we don’t need to break the API once again later.
• Bug 894331 and Bug 890203 are major blockers for landing this feature, and in fact, for most further work on asyncifiying places client code.
• Raymond figured the random orange in bug 818593 – Add file size to bookmarks restore UI, pending review mak

Project Updates

Australis

• Still making progress on perf bugs
• MattN and jaws are primarily focused on investigating and fixing the perf bugs, while Gijs, mconley, Unfocused, and mikedeboer are primarily focused on fixing P1 and P2 Australis bugs.

Thumbnailing

• Remaining blocker: bug 870100, actually using the background service in about:newtab. The patches there are r+’ed but cause lots of orange, so Mark filed bug 892875 to disable the service during non-thumbnail tests, but Dão and Gavin have raised questions about doing that. Discussion in progress.
• Other remaining blockers are ready to land: telemetry (bug 870104) and fixing a private browsing bug that caused an intermittent orange (bug 891169 and bug 893404 together).

SessionStore

• f+ for cutting saveState() into chunks
• fixed sessionstore regression (Fx 25)
• introduced dedicated sessionstore I/O worker
• work on converting sessionstore to Promise.jsm is continuing

Places API asyncification

• Mak fixed regression due to getPlacesInfo API code
• lots of brainstorming ongoing
• Mano working on design of a new async transactions manager
• Mak will investigate smart batches in Places views, needed for async transactions manager
