The Need To Know
(Release and system issues that may impact engineering this week.)
- Metro has been pulled from shipping in FF28 bug 981166
- QA is doing extra testing around this for the 28.0RC shipping tomorrow
- FF Desktop 28.0rc shipping tomorrow (Wed)
- FF 28.0b10 Mobile shipping later today
- Merge Day is next Monday
- Pwn2Own starts tomorrow, we are prepared for possibility of respinning FF28 over the weekend if some exploit is discovered (and fixed)
- Very unlikely to do a 27.0.2 as we are shipping 28 on Tuesday and should conserve resources as well as user update fatigue
|Next Merge: July 27, 2020||Next Release: July 28, 2020|
|Central: 80||Aurora: 54||Beta: 79||Release: 78.0|
|Unresolved Aurora 54 Trackers (non-security, not tracked for Beta)||Unresolved Beta 79 Trackers (non-security)|
Build Changes (gps)
(Build changes of which engineers should be aware.)
(Repo, test, and other information for engineers from the release engineering team.)
(System outages/upgrades and tree closures that impact engineering.)
- (On-going) Bugzilla issues of late:
- Max attachment ID was hit yesterday due in part by an accidental large increment of the autoinc value and by not monitoring the situation. Caused intermittent problems for several hours as we switched the column to unsigned bigint on all slaves and a few db inconsistencies that were manually fixed. Back to normal now; other columns updated at the same time, and bug filed for nagios monitoring.
- Slave replication lag; IT identified main culprit as being use of MyISAM, which locks tables on full-text searches (and there are some very, very big searches going on). Switching to InnoDB soon; more solutions, like moving long queries and polling to a separate slave, are being pursued.
(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.)

irc #planning Log From This Meeting
10:42 cpeterson: RyanVM: what makes 976479 a hot bug? It doesn't look like it has a lot of reported failures, if I am reading the bug correctly. 10:45 philor: cpeterson: freshly introduced so it doesn't have a high total, yet, but has a high rate, crashes so we have to retrigger the run, happens in pretty much any test so we have to manually star most of them 10:50 philor: cpeterson: yeah, combination of that and the way there's nothing we can do about it, since we can't just stop running mochitest-2 and mochitest-3 and browser-chrome on OS X, so it's going to have to become owned by and fixed by someone ... 11:03 cpeterson: https://wiki.mozilla.org/Platform/2014-03-11 11:03 dholbert: FWIW: there's a Mountain View office-moving brown-bag happening right now, if mountain view attendance is a bit low 11:03 jesup: khuey or jduell perhaps 11:04 khuey: hmm? 11:04 davidb: the OMGCHANGE should ramp up 11:05 davidb: (re australis moving to beta) 11:05 Noah_: Callek_disconnected: hmm, I'm not sure if you're online or not - was wondering if you ever got a answer to your old sync question? 11:07 khuey: jesup: what's up? 11:08 jesup: orange factor IPC issues on mac - they're looking for an owner (or someone to find an owner) 11:08 jesup: you were mentioned verbally by someone 11:08 dveditz_: "ran out of numbers" -- the db was obviously not made by mathematicians 11:09 khuey: lol do not want 11:09 jesup: khuey: the downside of not being there to object ;-) 11:09 philor: you thought just palming it off on smaug in the bug would be enough? 11:09 khuey: yes 11:09 mcote: dveditz_: :)
