OrangeFactor (ryanvm)

<Read Only>

• Past week's OrangeFactor: 4.15 (last week: 4.51).
• bug 906716 - Intermittent B2G emulator "timed out after 1000 seconds of no output" remains #1 by a wide margin.
• All Marionette tests are now hidden on the B2G emulator for an ongoing extremely high failure rate. Unhiding is tracked in bug 1081529.
• 22 intermittent failures fixed in the last week - &resolution=FIXED&o1=greaterthan&v1=2014-10-07&f1=cf_last_resolved&query_format=advanced&list_id=11367820 List - Thanks!.

CritSmash (dbolter)

• small uptick in risk factor.
• please remember to factor in security fix time for Q4 and 2015 planning.

MemShrink (njn)

• Jan de Mooij optimized the JS engine's shape representation, which gave a 7 MiB win on JS memory usage on AWSY.

GFX (milan)

JS (naveed)

<Read Only>

• Q4 Goals

Layout (jet/dbaron)

<Read Only>

• Q4 Goals Posted!

Media (jesup)

• Media Playback Q4 Goals Posted!
• Loop is in Beta now!
  • We've implemented throttling of visibility as this is a "beta" feature with a soft rollout for 34
    • This means that in Beta the Loop icon will be in the "Customize" menu, AND due to throttling you may not see it there initially unless you set "loop.throttled = false" in about:config
• Forwarding of video to PeerConnection is about to land in Nightly and will likely uplift to Aurora (most is there already).

Necko (dougt/jduell)

• Network-changed events for Linux/B2G has landed on inbound (bug 1008091): helps with lame-network wedges.
• Landed "set network offline on a per app basis" (bug 786419)
• Opportunistic Encryption (OE) for HTTP/2 (i.e. if server opts-in we'll upgrade http to use TLS w/o certs) has landed (bug 1003448). Akamai will be our first main use case.
• Almost done mopping up cache2 fallout bugs (bug 1074832)
• Looks like we can reduce memory usage and technical debt by merging parts of imglib cache with cache2 (honza, :seth)
• Resource timing has stuck in the tree, but e10s support bounced (bug 1064706)
• We'll be participating next year in an EU-funded academic/industry research project (NEAT) to explore ways to improve application protocols (something better than TCP) practically on the internet.

irc #planning Log From This Meeting

11:04 dholbert: cpeterson, I suspect more folks are watching on AirMo [I am, at least :)]
11:04 cpeterson: dholbert: what's on AirMo now?
11:04 jesup: Platform meeting does force people to actually *write* those notes....
11:04 dholbert: cpeterson, the eng meeting
11:06 cpeterson: jesup: *if* they update the wiki notes :)
11:06 cpeterson: dholbert: which eng meeting?
11:07 dholbert: cpeterson, lol :) the one right now, I think. snorp just finished talking about roku stuff
11:08 cpeterson: dholbert: oh yeah..
11:10 jesup: lmandel: 	mreavy	we will ramp up over a week or two depending on how the servers look, and how usage looks
11:11 lmandel: jesup: Thanks. Found about about this from pjarret. This was a surprise for me and for QE.
11:12 jesup: IIRC product (and maybe services) wanted that, though I wasn't directly involved.  Services may have been concerned about getting swamped all at once.
11:14 lmandel: jesup: Yup. I just didn't realize we were doing this on beta. I thought it was only release.
11:16 cpeterson: lmandel: fyi, tracking protection is still broken with e10s: bug 1055186
