crash picture going into 3.0b1
Wayne Mery
before shipping 3.0b1. We are behind in addressing top crashers for
3.0b1 because prior to this week it was impossible to rank trunk crashes
- due to lack of build symbols and crash server issues**.
For reasons stated below**, we must use custom reports to get a combined
picture of 3.0a3 and trunk:
-
http://crash-stats.mozilla.com/?do_query=1&product=Thunderbird&version=Thunderbird%3A3.0a3&version=Thunderbird%3A3.0b1pre&query_search=stack&query_type=contains&query=&date=&range_value=5&range_unit=days
omitting eudora crashers. and sqlite3_sql, which is Gloda and therefore
probably not applicable to b1 yields ...
Combined Ranking
1. imgRequest::NotifyProxyListener - Bug 457496
2. @0x14c0 (#1 on trunk)
3. nsTreeSelection::GetSingle - bug 456871
4. nsCOMPtr_base::assign_with_AddRef - Bug 445372
5. nsINode::GetCurrentDoc
6. nsImapMailFolder::NormalEndHeaderParseStream
7. nsProxyObjectCallInfo::RefCountInInterfacePointers - Bug 466318
(#2 on trunk)
8. nsCOMPtr_base::~nsCOMPtr_base - Bug 445372?
9. nsMailDatabase::UpdateFolderFlag - bug 450479 FIXED
Action list
1. 457496 hopefully will land Monday, with dmose or someone pushing.
2. @0x14c0 might mostly be
nsProxyObjectCallInfo::RefCountInInterfacePointers. Bug 466318 needs
work to get fixed by Monday.
3. bug 456871 - needs a dev?
4. Bug 445372 - needs analysis
5. nsINode::GetCurrentDoc - needs a bug
6. nsImapMailFolder::NormalEndHeaderParseStream - needs a bug
7. (see #2)
8. unclear if this is really Bug 445372, or something newer
In future few days the figures on crash stats should become more
representative, and getting Mac symbols and work on the crash server may
also help the rankings may change**. But I think the above is a good
hit list for triagers and developers to start focusing on - perhaps
nsProxyObjectCallInfo::RefCountInInterfacePointers in particular.
** Some problems remain but the situation is getting much better due to
work by gozer and many others. Windows symbols returned with
2008-11-20's build (ref bug 464247) after being gone for several weeks,
so we now have almost 6 days of good crash information. Mac symbols are
still lacking due to bug 445090/bug 466385. Canned topcrash queries
from the "top crash" button are currently not "accurate" due to Bug
461977 Duplicate Signatures in top crashers db; number crashes not
aggregated. Not also the Penelope group, whose crashers obviously
appear in the queries, are also working to get symbols so that those
crashes can be properly ranked and identified.

only seen in 3.0a3 crashes, so perhaps fixed by Bug 447835 - Crash [@
nsINode::GetCurrentDoc] while trying to print/print preview with iframe
that has documentElement removed
Mark Banner
I now have a fix posted for these (they are the same issue).
