It would also be nice if the checkins list only got spammed for actual
compile or test failures. I'm not all that interested in getting an
email just because a box got rebooted or lost its net connection for a
In terms of checking the buildbot status page itself, it would be a lot
more convenient if the "current/last build" field on the buildbot slave
details page was a hyperlink to that build's results page rather than a
mere number as it is now.

I haven't noticed that so much as the fact that a few of the buildbots
have been pretty much permanently red for quite some time. Some examples:
Checking the build results for this machine usually shows quite a few
different errors, although the latest addition to the collection is a
segfault in test_ctypes. Do we really support tru64 well enough to have
it as a build slave?
ppc debian unstable:
test_xmlrpc failing with connection reset by peer errors. I think
I've seen that on other platforms as well, but this one seems to do it
nearly constantly. (I don't know enough about the structure of that test
to know if a GHOP student could figure out the problem without access to
a machine where the test fails consistently - might be worth a try though)
test_urllib2net FTP tests are failing, apparently complaining that
SocketType expects two arguments rather than three. Probably a hard one
to figure out without access to a machine where the test is actually
failing (even my description of the problem involves some guesswork
based on reading the code near where the failure occurs).
I think a few of the others (such as hppa Ubuntu) also have issues.
It's gotten to the point where I only pay any real attention to about
half the trunk buildbots (looking at the status summary page, I would
probably investigate further if sparc solaris, g4 osx 10, XP-3, XP-4 or
x86 FreeBSD turned red after one of my checkins) and pretty much ignore
Would it be possible to distinguish the reliable buildbots from the
problematic ones in the build master? If such a distinction can be made,
it might then be possible to arrange for email to be sent to the checkin
list only if one of the reliable buildbots fail.
