Currently processing multiple pull requests in a batch is just a matter
of a script doing rebases in a loop against a special branch that starts
out at master HEAD, testing the final result of that and then merging
the final special branch.
Ideally the same process could be used, just with merge commits in the
loop instead of rebases. Is that another way of saying what you
described above? Or is there a problem with the final merge of the
Yes we could write something to mirror the old way and use merge commits and PR linking
and so on. My suspicion is that the staging process would be faster because you just click
the green button on "clean" changes. The test process could kick off
automatically and email later, or to prevent duplicate runs we could just have an extra
launch step (click the run button on brontes once you are done merging).
It's pretty important that this be efficient. The large majority
get merged in sizable batches, because the heavy costs are the test
execution time and the context switch on the part of the merger.
I agree thats the goal.
