Weekly bug summary report added

[Daniel Berlin]

I ported GNOME Bugzilla's weekly bug summary report to GCC Bugzilla, in 
hopes it would be useful (I needed a 10 minute break from writing a 
paper).

Gnome uses a somewhat old version of bugzilla, 2.10, so it really was a 
port

http://gcc.gnu.org/bugzilla/weekly-bug-summary.cgi

It's also now linked from the reports page.

For those who've never seen it, it looks something like this, except 
prettier (all the numbers are hyperlinked to the list of bugs in 
question, it's colorized, etc):

GCC Bugzilla Weekly Summary
	  	

Some weekly bug summary info for gcc.gnu.org.
Total Reports: 1529 (63 reports opened and 66 reports closed in the 
last 7 days. Including enhancement requests)
Top 15 GCC modules with the most reports:

(the second column excludes enhancement requests, the other columns 
cover all reports)
Product	Currently OPEN Bugs	Opened in last 7 days	Closed in last 7 
days	Change
gcc 	1421 	+63 	-66 	-3

Top 15 people who resolved the most bugs in the last 7 days:
Position	Bugzilla User	Number of Bugs Resolved

2 	hubicka gcc gnu org 	9
3 	ehrhardt mathematik uni-ulm de 	4
4 	ebotcazou gcc gnu org 	3
5 	paolo gcc gnu org 	3
6 	neil gcc gnu org 	3

12 	billingd gcc gnu org 	2
13 	mmitchel gcc gnu org 	1
14 	aph gcc gnu org 	1
15 	zlomek gcc gnu org 	1

It's actually pretty customizable, it just doesn't expose it in a nice 
interface (for instance, the number of days, n top people, products to 
scan, keywords to restrict to, etc, is passable as a form variable).

I can also add a bit of code so it can tell you the weekly bug summary 
for a given target milestone if that would be useful for release 
tracking.
