*(catlee) Proposed tree closure for Tuesday March 5th 16:00 - 24:00 PT for bugzilla downtime | |||
*(gps) Proposed tree closure for (soon) for moz.build landing {{bug|784841}}. | |||
* FF20b1 for desktop released Friday, FF20b1 for mobile released yesterday with important update fixes | |||
* FF21.0a2 unthrottled last Friday | |||
* ESR10->17 updates unthrottled yesterday | |||
* A FF19.0.1 re-spin to resolve critical issues is NOT expected for mobile | |||
* A FF19.0.1 desktop re-spin is expected today for {{bug|830531}} | |||
** Once spun up, we'll need positive verification that the re-spin prevents the issue | |||
** If there are no other drivers (PDF.js stuck!), we can unthrottle FF19.0 for non-Win8 as soon as possible (moving forward with this now) | |||
* FF20b2 expected to go to build today, released before the end of the week | |||

;Stability Wins<br> | |||
* The team worked hard to pull together patches to address the DB locking crashes for Firefox 20 beta 1 which shipped yesterday: | |||
** {{Bug|843029}} - Add more retries to ensureDatabaseIsNotLocked | |||
** {{Bug|843361}} - Dump list of open files if we fail to unlock the DB | |||
** {{Bug|732902}} - java.lang.IllegalStateException: at android.widget.ListView.layoutChildren(ListView.java) with Adapter | |||
** {{Bug|836924}} - java.lang.NullPointerException: at org.mozilla.gecko.Tabs.getContentResolver(Tabs.java:212) | |||
* Awesome find/fix hit trunk for: {{Bug|839882}} | |||
;Memory, Responsiveness, and Usability | |||
* Nice responsiveness improvement hit central yesterday with the landing of {{Bug|843888}} - LayerView has 1 overdraw | |||
* We are very stoked \o/ on the landing of {{Bug|716859}} and the patch for {{Bug|829747}}. The build we are showing at MWC contains both these patches | |||

* Feb 21 [[Performance/Snappy/2013-02-21|Minutes]] | |||
;Startup & Shutdown | |||
* {{bug|810454}}: Read-ahead entire sqlite cookie DB on DB connection open | |||
** Experiments show 50% faster DB open time for a larger cookie DB (1.5MB) | |||
** 87% regression for smaller cookies DB (512KB), but small in absolute terms. See bug for data & details. | |||
** Plan to do a Telemetry trial to verify benefit in the field | |||
** Pre-loading LocalStorage DB {{bug|842777}} and Flash shared library {{bug|836488}} | |||
;Tab Strip | |||
* {{bug|828097}}: We now have Telemetry for Tab animation smoothness | |||
** Tab animation intervals are good when opening a blank page, not very good when newtab preview is enabled (regardless of browser.newtab.preload), especially on slow systems. | |||
** Telemetry: http://goo.gl/LHjTZ | |||
* {{bug|838758}}: Gradient cache keys were too precise. Avi landed a patch to key the gradient cache on gradient stops instead. | |||
** This patch eliminates big memory spikes on some systems (HD4000) - {{bug|837542}} | |||
** D2D speedup 20-25% for tab animation. | |||
* {{bug|837885}}: We're working with fx-team (MattN, mconley) on Australis performance | |||
** Benchmarks: http://goo.gl/TOXLe | |||
** Now at about 15-20% regression from default theme on slow systems | |||
* Timer interval irregularities hurt animation smoothness: | |||
** {{bug|842967}} - timer may retarget the same timestamp | |||
** {{bug|590422}} - remove timer compensation/smoother | |||
;Content | |||
* {{bug|842852}}: Improve LocalStorage performance by check-pointing the WAL log more frequently + preventing latch-up of reader and writer threads. | |||
;Hangs | |||
* {{bug|825588}}: Paolo landed the skeleton for a new downloads API. Iterating on features and will eventually port over callers | |||
* {{bug|789348}}, {{bug|820834}}: Marco working on removing uses of LocalStorage from about:home | |||
;Add-ons | |||
* {{bug|810149}}: Addon Manager recursively scans unpacked addon directories for changes on startup. We would like to only check extension install manifests | |||
** However, we're seeing very high number of Telemetry reports of unpacked addons getting updated without any changes to their install.rdf. | |||
** If you see "addonManager: {"modifiedExceptInstallRdf": n > 0, ...}" in your about:telemetry's "Simple Measurements" section after starting Firefox, please contact Irving or Vladan. | |||
;Tools | |||
* We'll soon begin receiving reports of any Firefox late-writes (part of making shutdown faster) | |||
;Other | |||
* {{bug|840651}}: Telemetry ping storm from a few machines, idle-dily firing too much? | |||

If you are interested in attending MemShrink meetings, please feel free to do so. The next one is Tuesday, March 5th at 2pm PST (watch for Jet's announcement email to dev-planning). The MemShrink regulars have some expertise when it comes to the DOM, JS engine, cycle collector, B2G and Fennec, but participation and engagement from people who know about things such as gfx, images, layout, jetpack, and front-end would be extremely welcome. Feel free to contact nnethercote if you want more information. | If you are interested in attending MemShrink meetings, please feel free to do so.
