It took half a year (including a long pause), and the Firefox triage is finally over. The last part, reviewing 120 bug reports took about a month. Starting with 324 bugs, the triage ended with 10 open bugs which I left for the maintainer to handle himself.
Although I didn’t keep record about the exact numbers about how many bugs were found to be fixed, it seems that ~250 bugs were closed (fixed, not relevant any more, whatever…). This leaves ~70 bugs to be valid (all reassigned to Iceweasel and got the right version info).
As I see it, the biggest problem of the large package maintainers have is to figure out if the bug is Debian specific or upstream only. The latter should be reported upstream by the users (when possible) to lower the pressure on the maintainers.
I my recent triages I saw a lot of upstream only bugs reported only in Debian, since the maintainers can’t be just “bugs forwarders”. It might work well in small packages, but this doesn’t scale up. So when possible, please try and report bugs upstream…
Anyway, I’ll probably initiate another triage for Iceweasel when version 3.0 will enter testing (probably post Lenny).
