I’ve just finished my first week at Mozilla. So far it’s been a blast. They’ve put us up in a really nice temporary living apartment complex (pictures and yes that is a 40 person hot tub), the other interns are all really nice, and well, it’s California.
This week we had a poker game / movie night. I was in on poker and turned $10 into $30, which should keep from an ATM a little bit longer. They’ve also been feeding us lunch this week; there’s a stock of good snacks & cereal, so I don’t have to eat breakfast before work (although I have been).
Anyway, on to Firefox.
So I am on the Firefox team for the summer. My initial goals include working on profiling startup and improving shutdown. Neither of these are one day tasks, not even 1 week. In fact, both seem pretty lofty and fun to work on.
The improving shutdown part is where I’ve been focusing first - it’s something that has bothered me personally. The behavior is both inconsistent and can be pretty annoying. For example, if you close the last window vs. doing File|Exit (and have “Clear Privacy on Exit”) checked, you will have different outcomes when you try to restore your session. Not only that, but there are several different dialogs that can pop up. Then take into account leaving the Downloads window up when you close the last window — your session restore is screwed (at least last I remember). That is not the expected behavior.
So all this week I’ve been digging through the Firefox source code with MXR. I haven’t written a single line, just reading & taking notes. It’s not simple. Shutdown (or “Exit” or “Quit”) goes through a number of steps and then broadcasts a
quit-application-requested message. Other objects observe specific messages, so all the ones that observe
quit-application-requested are then triggered. Some of these in turn trigger dialogs, set preferences, close windows, and so on. Assuming all goes well there,
quit-application-granted and subsequently
That said, it’s been a fun (albeit exasperating at times) week and I’m looking forward to the rest of the summer.
