You raise some very good points here.  Until the Semantic Web becomes a
reality, however, and we all start writing all our documents in perfectly
cross-linked XML, I'm afraid the best we can do is identify reasonable
tools and practices to help us live with our ever-growing tangled web of

As Dmitri suggested later on, automating the cross-linkage of bug reports
and changesets should be straightforward and is something we should look

Linking Sun bugs back to Bugzilla bugs can also be automated, by scanning
Bugzilla bugs for sunbug= properties and planting corresponding reverse
links in the Sun bug database.

Linking code reviews on to, and from, the bug
databases should be possible with a bit of work.  If people consistently
name their top-level review directories with bug numbers then it's easy;
if not then we'll have to come up with some other way to convey that

The harder problem is e-mail.  We can encourage people to use Bugzilla
comments, but the e-mail habit runs strong and deep -- especially within
Sun -- so that's likely to prove an uphill battle.  Fortunately Google
is pretty good at looking for contiguous strings of digits; I'm afraid
that's the best solution that I know of in the near term.

In the longer term it'd be nice to have a tool like Review Board set up
for code reviews, but that's not something we'll have time for in the
next few months.

FYI I've created a few (Bugzilla!) bugs to capture the linkage ideas
that could be implemented near-term [1].
