Yes, when possible. Or at least just bundle related commits together. My
goal is still to have some automatic feedback on test results back to
list (or maintainer) for each run, but at this time the result still
needs too much manual investigation to make sure it’s not a false alarm
if things break.
This could be tricky. We have to couple the pushing of commits to the
running of the CI tool on those commits. Hmm. So the commiter would need
to:
1. Push the next minimum set of commits that are needed to build (ideally
that'd be 1 commit)
2. Check the CI tool and wait till it has run
3. Go to 1
?
This is the CI at https://ci1.netdef.org/browse/QUAGGA-QMASTER right?
Better would be to remember the last head the CI ran on, then after more
commits are pulled in, go through each commit and do the CI on each? E.g.
if abc123 was the last commit ID, then get the list of more recent commits,
checkout and run the CI in that with something like:
for COMMIT in $(git rev-list abc123..); do
git checkout $COMMIT && runci() || exit ...
done
Unfortunately not without rewriting the whole CI system (as fas as I know).
Atlassian Bamboo (which I use)
and Jenkins work in a way that they get triggered by git server telling them
that new commits are available
or by polling a git server for changes.
And they don't support doing something akin to 'git bisect' to find the
commit? Surely others must have run into this?
Hmm, seems so:
https://issues.jenkins-ci.org/browse/JENKINS-12972
https://jira.atlassian.com/browse/SRCTREE-1125
Also, your suggestion would break builds in the rare case where multiple
commits need to be tested together to build a working system (not sure
if and how often this might happen).
Yeah, ideally every commit should be 'golden' and produce a buildable and
workign tree. The ideal and reality have a tendency to disagree every now
and then though, despite best efforts. ;)
