[Buildbot-devel] Adding a Changelist to Buildbot Notification emails

I am not sure whether there is a built-in functionality for that. I kind of
hope not, since i took the time to write my own custom bit of code for it.
I wrote a script to compile and print a list of changes from a range of
revision numbers, then wrapped that in another bit which pickled out a
mapping of build numbers to builders. Then in the MailNotifier code, if a
build was successful I added a hook to call in, get the diff of svn numbers,
and return the list of change notes which are then pasted into the email.
My clever engineers have now started adding the bugzilla url for addressed
issues directly to their svn change-notes, so that bug links appear in the
Note that (at least with 0.7.9) to get this to work I also had to enable the
successful build case. In the existing code base it recognized failing
builds and all builds, but would assert out on the successful builds only
Regarding the properties you are asking about, you should be able to get
them out of the builder's properties, which is available from the
MailNotifier if you are overriding code there. The only one I am not sure
about is the person who ordered the build. If you are ordering the builds
through IRC it should be fairly easy to get the handle of whoever sent the
build request to the Bot, though of course that's not really any guarantee
unless you enforce a strict nickserv policy. If you are ordering builds
through the web interface I am less familiar with that.
For your other idea, running the build through a scheduler, it seems like
the easiest, shortcut way to manually force a scheduler to fire off at will
would be to add a dummy file to the tree (say "buildMe.txt.") and just check
it in when you want your builder to fire off. I'd personally prefer using
the IRC interface, but I don't see why that wouldn't work. I am not sure
how to retrievethe "last successful" build in this case.
It seems though that if you already have the code to generate the changelist
given 2 svn revisions as bounds, you've got a lot of the work for the
solution I used already done. If, at the simplest, you create a dict of
builder names -> last succesful build numbers which gets pickled in/out on
requests/changes, and leverage that with your changelist generating code,
you should be able to make a couple simple changes to MailNotifier to get
the behavior you want.
Let me know if any of that doesn't make sense...it's 630 in the morning, so
it's completely possible that I am writing sanskrit without realizing it.
