status of trunk

Posted by Will Kahn-Greene

Over the last week I’ve been coming up to speed on the architectural changes that occurred when Ben landed the new widget code. I’ve also been hooking up menu items to their respective behavior and fixing bugs on the Linux and Windows platforms. In many cases, I’ve been re-implementing the behavior using the new messaging system which has required me to read through the “old” code and figure out what the behavior used to be. Progress was slow at the beginning, but is picking up now.

You can see checkins progress in the Trac timeline.

There’s still a lot of work to do to get things working again, but things are progressing.

So, why all the trouble? Why not just leave it as is? Off the top of my head:

  1. Miro’s UI is no longer rendered using HTML templates. w00t!
  2. It looks like overall memory usage is lower by around 20%.
  3. Memory usage of Miro when displaying feeds with lots of items scales much better.
  4. Miro’s faster at displaying feeds with lots of items (where “lots” is defined as > 50).
  5. Miro on Windows is no longer a XULRunner application; instead we’re embedding XULRunner for web-browsing. XULRunner is a great platform, but this change makes Miro a Python application on OSX, Linux and Windows and we can unify our toolset. That’s a huge win for us and reduces the amount of work it takes to maintain all three platforms.

Regarding the performance gains, I’m seeing those on Windows and Linux, but I definitely haven’t spent a lot of time doing rigorous measurements. Treat them as if they were wild unsubstantiated rumor. I haven’t used Miro on Mac OSX enough to notice anything there, yet.

Getting there…!

    So I guess the better question to ask, is when will the trunk be deemed fixed in relation to the previous post when the trunk was broken? I anxiously await to test, but have been waiting for updates.

    I’ll try to do weekly updates until we get to something stable-ish. Beyond that expect me and other devs to be pretty quiet. We’re busy trying to get things done quickly.

    In terms of estimates, it’ll be done when it’s done. Any answer more complex/accurate than that requires someone to spend time to do it.

    In regards to testing nightlies and such, you should talk to Janet as she heads up QA.
