Australis Weekly Update

We currently have 3 landing blockers. This update will be a bit longer than normal, because I just wanted to provide a bit more detail on things this time around. * bug 889758 (tpaint regression) * bug 880611 (ts_paint regression) We retitled these two bugs for clarity, and because they actually overlap. Briefly, ts_paint measures how long it takes for the browser to start and launch its first window, whereas tpaint only measures opening a new window (once the browser is already running). Improvements to tpaint should also improve ts_paint, whereas the reverse is not always true. Current focus is on tpaint. We've made some improvements, but progress continues to be slow. Main areas we're looking at include: - Use of chromemargin (for tabs-in-titlebar) on XP. Looking like a platform issue, bug 894099 - Something in the the various patches for bug 770135, jared is working on narrowing this down further. - We have a collection of other small items identified from profiling. * bug 819963 (mochitest-bc needs to be split) This is new, but has a simple workaround. The mochitest-bc test suite has a defined 120-minute runtime limit, which mozilla-central is already close to exceeding. New tests on UX manage to push it over the threshold. The long-term fix is to split these tests up (as we already do with mochitest-1 thru mochitest-5), but in the short-term we can increase the 120 minute timeout. (Note that this bug was filed 6 months ago against mozilla-central, taking 90 minutes for a run.) Justin
