- There were 1,221 code changes to our mercurial-based repos. Over the month, these triggered:
- 13,653 build/unittest jobs, or ~18 jobs per hour.
- 6,484 talos jobs, or ~8.7 talos jobs per hour.
- The try server data before 19th Aug was lost, because the try server hg repo had to be reset. Even without 19 days of TryServer data, we are almost the same as last month, and last month was a record month. This was definitely a busy month.
- The mozilla-1.9.2 project branch was added during August and is now being tracked.
- Its interesting that more checkins are happening during the PST day; its the first time I’ve seen such a night-and-day difference in traffic (pun intended). I don’t know how much the developer work week held in Mountain View skewed the numbers, but its worth noting.
- We are still not tracking any l10n repacks, nightly builds, release builds or any “idle-timer” builds.
Here’s how the math works out:
The builds/unittest/talos jobs triggered by each individual push are:
- mozilla-central: 13 jobs per push (L/M/W opt, L/M/W leaktest, L/M/W unittest, linux64 opt, linux-arm, WinCE, WinMo) and 6 talos jobs
- mozilla-1.9.1: 12 jobs per push (L/M/W opt, L/M/W leaktest, L/M/W unittest, linux64 opt, linux-arm, WinMo) and 5 talos jobs
- mozilla-1.9.2: 13 jobs per push (L/M/W opt, L/M/W leaktest, L/M/W unittest, linux64 opt, linux-arm, WinCE, WinMo) and 5 talos jobs
- electrolysis: 12 jobs per push (L/M/W opt, L/M/W leaktest, L/M/W unittest, linux64 opt, linux-arm, WinMo) and no talos.
- mobile-browser: 5 jobs per push (WinMO m-c, linux-arm m-c, Fennec linux desktop, linux-arm tracemonkey, WinMo electrolysis) and 2 talos jobs.
- places: 12 jobs per push (L/M/W opt, L/M/W leaktest, L/M/W unittest, linux64 opt, linux-arm) and 6 talos jobs.
- tracemonkey: 10 jobs per push (L/M/W opt, L/M/W leaktest, L/M/W unittest, linux-arm) and 6 talos jobs.
- try: 9 jobs per push (L/M/W opt, L/M/W unittest, linux-arm, WinCE, WinMo) and 6 talos jobs.
UPDATE:fixed math for #build/unittest jobs, after nthomas pointed out that WinCE was missing.Thanks Nick!! joduinn 02oct209
Mozilla released Firefox3.5.3 on Wednesday 09-sep-2009, at 16:11PST. From â€œDev says goâ€ to â€œrelease is now available to publicâ€ was approx 16 days (16d 18h 35m) wall-clock time, of which Release Engineering took ~1.5 days (1d 13h 11m).
21:37 23aug: Dev says â€œgoâ€ for FF3.5.3
08:45 24aug: FF3.5.3 builds started
11:50 24aug: FF3.5.3 linux, mac builds handed to QA
13:38 24aug: FF3.5.3 signed-win32 builds handed to QA
05:41 25aug: FF3.5.3 update snippets available on test update channel
13:14 01sep: Dev & QA says “go” for Beta
13:23 01sep: FF3.5.3 update snippets available on live Beta channel
01:53 09sep: Dev & QA says “go” for Release; Build already completed final signing, bouncer entries
05:34 09sep: mirror replication started
06:42 09sep: mirror absorption good enough for testing

14:58 09sep: update snippets available on live update channel
16:11 09sep: release announced
1) A significant amount of RelEng time was spent idle after the “go” was issued, just waiting. Specifically if “Dev says go” late night PDT, then nothing happens until the RelEng person wakes up in his timezone. If we exclude these long waiting times, the time for Build&Release drops to under a day (0d 22h 45m). I believe that is our fastest yet.
2) Our blow-by-blow scribbles are public, so the curious can read about it, warts and all, here. Those Build Notes also link to our tracking bug#511469.
3) The FF3.5.3 release was done at the same time as the FF3.0.14 release, without causing any delays to either release, and both still being super-fast release(s). Nice to see! 🙂
Mozilla released Firefox3.5rc3 on Tuesday 30-jun-2008, at 08:00PST. This was the formal Firefox 3.5.0 release. From â€œDev says goâ€ to â€œrelease is now available to publicâ€ was approx 6 days (6d 16h 05m) wall-clock time, of which Build&Release took just over 2 days (2d 8h 45m).

1) Firefox3.5 was the first time we did a major update at the same time as the release. This caused additional RelEng and QA work and is included in the times above.
2) Our blow-by-blow scribbles are public, so the curious can read about it, warts and all, here. Those Build Notes also link to our tracking bug#499687.
3)The extra long wait before the end of the release, was to wait for feedback of possible issues from beta users of 3.5rc3, as well as technical and media preparations specific to this large scale release event.
Mozilla released Firefox3.0rc2 on Wednesday 04-jun-2008, at 16:25PST. From â€œDev says goâ€ to â€œrelease is now available to publicâ€ was just under 7days (6d 22h 25m) wall-clock time, of which Build&Release took almost 2.5 days (2d 11h 06m).

16:25 04jun: release announced
1) Firefox3.0rc2 was the last full-build-across-all-platforms release we did in the run up to the release of FF3.0.0. The formal FF3.0 release was rc3. However, as rc3 required a rebuild of mac only, with no new linux/win32 builds, it didnt make any sense to measure wallclock times on just that!
2) Our blow-by-blow scribbles are public, so the curious can read about it, warts and all, here. Those Build Notes also link to our tracking bug#426307.
3) I couldn’t find the times at which the mac-only respin was declared, or at which the mac-only respin builds started, so I calculated the times as worst-case for RelEng. If anyone has those times, could you please let me know?
4) There were some complications during this release caused by problems with netapp hardware failures while doing the release. For the curious, the details are in bug#435134. This required RelEng and IT to do some nice cross-group coordinated juggling, to avoid delaying the release.
All the activity around netbooks which I saw while I was in Japan earlier this year made me curious. While they might be good for casual/student use, would they be sufficient for someone who works at his computer most of the day? Even though I’ve been a very happy with my 17inch MacBookPro for the last few years, I decided to keep an eye on these new netbooks, and be willing to experiment if something suitable came along.
The big thing for me was finding something with a usable keyboard. One good contender was the HP2140; I really liked the keyboard, and the very solid case, but the awkward touchpad/buttons and slightly-too-small-display kept me away. Then I saw the 11.5inch Acer Aspire One which had:
- fullsize keyboard, I liked it even more then the HP2140 keyboard
- 11.5″ screen (1366×768)
- 2GB ram
- 250GB disk
- 6cell battery
- 1.3GHz Intel Atom cpu
- model# AO751H-1893. (Interesting note is that the Acer Aspire One is actually a series of different netbooks. They all look the same when shopping online, so model#s are important. The first part of the model# is about the screen / physical size, so AO751H-xxxx is for the 11.5″ display, AOD150-xxxx is for the 10″ display and AOA150-xxxx is for the 8.9″ display. The last 4 digits of the model# is about the RAM/disk/O.S. and 3-6cell battery configuration.)
I’m still getting used to the Acer, installing software etc, but here’s some first impressions:
- keyboard: this is great, I liked it even more then the HP2140 keyboard. Somehow Acer managed to get a full sized keyboard onto what was basically a very small, light, device. I’ve used it now for a few multi-screen-long emails/blogs, and still really like it.
- screen: while this is obviously smaller then my 17″ MBP, it is big enough that I find it surprisingly workable enough without too much scrolling around.
- size&weight: I know the Acer Aspire One is smaller and lighter than the 17″ Mac Book Pro. However, as a fanatical one-carry-on-bag-only traveler, I was amazed at how much extra room it left when packing my travel bag. Carrying between meetings is now so trivial that I worry about putting it down someplace and forgetting where I left it!
- 6 cell battery equals *long* life. A typical day of a few hours usage between meetings throughout the day, means that the same one charge lasts across two days. Lets see how much that degrades as the battery gets older, but the difference from my MBP is life-changing. I used to carry an extra battery, and continuously seek out power outlets in meeting rooms and airports. Now, I just use one battery, can sometimes forget to bring the charger with me to the office and its ok.
- Vista came pre-installed so I reimaged with Windows7 Release Candidate, which works better then Vista afaict, except for an annoying need for manual refresh of desktop when resuming from suspend/hibernate. I’ll try Windows7 for a while, and see how it goes, before I seriously consider installing linux.
- slow CPU, little RAM; I’ve had to change my normal habits of running with 200+ tabs/windows and lots of concurrently running applications. Now, I make sure to focus on one thing at a time, and close all tabs/windows/applications as soon as I’m done. I’ve also noticed that with the MBP I’d typically wait to use it once I had a desk to work at, but with this netbook, I’m far more likely to whip out this Acer and do a quick item on-the-spot, regardless of location. It feels far less intrusive to use when others are around. Whether this is a good/bad thing is still unclear, but it is a change in my behavior triggered by the design of this new machine, so I wanted to point it out.
- thin case: this makes me wonder how rugged it is, and how long this machine would survive the abuse of being tossed into my bag, cycling to work, long distance travel, etc. So far so good, but the MacBookPro, and even the HP2140 feel a lot more solid.
- screen: A nit. The glossy screen has reflective surface, so backlighting can be annoying. In use so far, its been easy to reposition to avoid this, but I’d definitely prefer a matte screen to reduce this.
- keyboard: A nit. For dim lighting situations, I miss the keyboard backlighting on the MBP.
lack of bluetooth seems silly, especially as some of the bluetooth specific control keys are present. Seems to be an available option in some locales, but why not everywhere? update: I’ve since discovered a little switch on front left underside which toggle bluetooth on/off. This is in addition to the keyboard fn-F3 setting. Not the most intuitive design, but it does work. joduinn 22oct2009
I’m using this Acer to write this blog post, and while traveling this week, and so far I really like it. Lets see how it goes over the coming weeks!
As an aside, I found it interesting how few applications I had to install on this new machine. The complete list of what I installed is:
- putty (for ssh)
- OpenOffice (havent used this yet, but seemed useful)
- (The only thing I miss is “Things”, which is a Mac-only to-do list application)
Its early days still, so if I find myself installing other applications over time, I’ll update this list. However, so far its a very short list, and mostly geared around accessing information/programs/data on other remote machines. After all the talk about “cloud computing”, “hosted services” and “moving to the web”, I was actually kinda surprised to see how close to reality this seems to be… with the obvious endorsement of the whole netbook concept.
I’m curious – what other applications (apart from the ones listed above) do other people in Mozilla use?
(For the curious, here’s a flickr stream of photos from this year.)
Between 27July and 27August, we shipped the following releases:
- Funnelcake 9
- Firefox 3.6a1
- Firefox 3.0.13 (with refreshed MU for manual CheckForUpdate)
- Firefox 3.5.2
- enabled FF 3.0.13->3.5.2 Major Update for idle-background notification
- Martin 1.0
- Thunderbird 188.8.131.52
- Fennec 1.0b3
…and in progress this week are:
- Firefox 3.0.14 (with refreshed MU for manual CheckForUpdate)
- Firefox 3.5.3
- Fennec 1.0a3
That is quite an impressive list of releases from Mozilla in such a short time, and great to see how all the different groups worked together to make it all happen. However, when you put those releases in context of everything else that happened in RelEng this month: setting up new branches for place, electrolysis, mozilla-192… and recovering from a colo outage in record time… and enabling l10n nightly updates… and solving an imaging problem and then spinning up a bunch of mobile devices… all while some folks were on vacation… *and* while doing all those releases! Wow.
I am immensely proud of how the RelEng group handled the last month – its been quite a rush, and throughout it all, everything was handled calmly, smoothly and professionally.
