10 releases in 9 days

Between Wed (8th) and Fri (17th), RelEng did ten complete releases. In a few cases, at the last minute the release was not shipped to end users because of another release starting immediately, but all the work had been done already.

While doing all these releases, RelEng also set several new speed records – Firefox releases in 8-9 hours, Fennec releases in ~5 1/2 hours. Nice work. Calmly done. Great to watch in action.

  1. Nice job of releng on those for sure, you guys are doing awesome work!

    That said, for betas, that’s not the height of it, that’s just the beginning… 😉

  2. This is impressive work! Keep it up.

    I would love to see posts about infrastructure and release process changes/scripts you had to make to speed up releases, what you learnt during the 4 to 5 switch and how that will affect further releases.

  3. @Nikhil if you look at https://bugzilla.mozilla.org/show_bug.cgi?id=hg-automation you can see a bunch of bugs that got resolved since the beginning of the year.

    The improvements weren’t specific to the Firefox 4 to Firefox 5 switch but the many many quarters of improvements.

    The latest improvements that helped us the most were email notification at different stages during the release and auto-signing.

    It was awesome to go home knowing that the automation will keep everyone in the loop and that if everything went well required no human interaction after triggering the release 🙂
