Bug stats in the Mozilla world
After reading Kairo’s article about bugs triaged in Seamonkey these last few weeks, I wanted to do a quick comparison between main products released by Mozilla: Firefox, Thunderbird, Seamonkey, Camino, Bugzilla, Calendar, and I also included Core and Toolkit. The comparison is interesting, as you can see below (click the image to make it larger… and readable).
As you can see, the two popular products of Mozilla, Firefox and Thunderbird, have many unconfirmed bugs. There are as many unconfirmed bugs as fixed bugs. This surprised me a bit when you know that with such a wide userbase and the QA team, bugs should become confirmed pretty quickly… or quickly be triaged as invalid or wontfix. Maybe are these products so popular that bugs are being filed much faster than they are resolved? I don’t know (someone more involved in these two products would know more).
The other six "products" (products as defined in Bugzilla) have a pretty similar behavior: only a few unconfirmed bugs, and two to three times more fixed bugs than open bugs (bugs marked as ASSIGNED and REOPENED have not been included as they are negligible compared to bugs marked as NEW). Does it mean triaging is more efficient and bugs fixed more quickly in these products, or does it mean these products are less popular, giving more time to developer teams to triage and fix bugs?
Anyway, my goal is not to say who is good and who isn’t in triaging and fixing bugs quickly. I just thought this graph was interesting. You are free to interpret it as you want.
