Re: no correlation between the number of bugs

Of course because some number of those are internal IT and desktop support related bugs that have little to do "bugginess" of the products.

[Note: edited by Gerv to change tables (which MT doesn't allow) into bulleted lists (which it does)]

Some stats for those interested:

All bugs, by Status:

So that makes 62,809 (~16%) bugs still open and 331,300 closed. (It doesn't add up to 400,000 because some bugs numbers are no longer in the database for whatever reason). Of those open, 75% (40,710) have been confirmed at one point and 7.5% are listed as ASSIGNED.

Explicit enhancement requests make up 35,284 bug reports (open or closed). There are "only" 37,306 confirmed non-enhancement bug reports, and many of those will end up as DUPLICATE, WFM, WONTFIX, etc. (Moreover, many bug reports are really feature implementations, code refactorings, or other forms of enhancement, so the number of actual bugs should be much lower still).

Closed bugs, by Resolution:

So ~33% were marked FIXED (although not all have patches attached, as bugs fixed by other bugs are alternatively marked either WFM or FIXED).

All bugs, by Product:

That's a whopping 43% in Core, 20% in the Suite, 15% in Firefox, 4.6% in Thunderbird, 3.1% in Bugzilla, and 14% for all other products put together. Of course you have to remember that most other products have Core as their backend, and all these numbers will change after the Bugzilla reorganization.

Open bugs, by Product:

That's 42% in Core, 16% in Firefox, 12% in Suite, 9.0% in Thunderbird, 5.4% in Tech Evangelism, 4.0% in Bugzilla, 1.8% in Calendar, and 10% for all other products.

The components with most open bugs are, by far, the "General" ones:

For the last one year period, b.m.o has been growing steadily at the following rates in each category, in bug reports per day:

That's an average of +111 bug reports per day, with 96.5 (87% of that) bugs being closed per day, for a net growth of open bug reports of 14.7 per day.

The growth rates by resolution:

41 fixes a day sounds pretty good to me.

14 new bugs per day!

no wonder these products have a bad rep

Congrats ed on completely missing the point. Did the whole point about how many different products are being tracked and the variation in what a given "bug" coule be (a dupe, an enhancement request, a spinoff, etc.) go completely over your head? Quite frankly, given the magnitude of how much Mozilla's Bugzilla is tracking and the reasons various bugs are filed, I think an average of only 14 new submissions per day is quite impressive actually. Your post smacks of complete ignorance about how things work for projects of this sizes and bug trackers as large and complex as Bugzilla are.
