Status: RESOLVED FIXED

(Core Graveyard :: Talkback Client, defect)

Description

[chris hofmann]

make sure we have run though the top 20 crashers and have bugs on file...  jay
can use help where people want to pitch in.   until we get reports published it
going to be a bit quirky, but we can publish reports and comments here until the
scripts and tie-ins to bugzilla  I'll attach something here soon.

helpers,  be sure to check for existing bugs and just add the topcrash keyword
to those, before opening new bugs with the topcrash keyword...

thanks

Comment 9

[chris hofmann]

for that last one we should also pull together deCOMtamination folks and see if
there are more areas to check and more bugs to file to be more defensive in
deCOMtamination changes...

oops, didn't mean to do that

Attachment: Topcrash Table for M17 beta and rc1 as of 4/28

I've been tracking topcrashers on a spreadsheet as I look at Talkback data for
the latest milestones.	This table shows the ranking by date and includes any
bug info that I have found for that crash.

If people find it useful, I can update the attachment once a week.

Comment 19

[Asa Dotzler [:asa]]

all dependencies are resolved. Do we need to add more dependencies or resolve
this bug?

Comment 20

[Jay Patel [:jay]]

I think we started adding dependencies early, but since the topcrash rankings
change often, I haven't added any new bugs.  

Instead, I have been updating the attachments with the latest topcrash table so
we can keep track of topcrash fixes with the 1.7 branch.  We can leave it open
so people can look at the table if they want to see what bugs need to be looked
at, which ones have been fixed and catch possible regressions.
