While commit date is monotonically increasing, it has the problem that at
certain dates there are very few commits, at others many. When doing
bisection by hand, one does the revision computation (min+max)/2 in head
(it doesn't have to be precise of course, just roughly, and isn't perfect
either, because in svn all of trunk and branches contribute to the revision
numbers), with dates it would be division into further uneven chunks.
Could we tag the branchpoints, say when we branch off gcc 10, we tag the
branchpoint as tags/r11 and then we could use r11-123 as 123th commit on the
trunk since the branchpoint, and let bugzilla and web redirection handle
those rNN-NNNN style identifiers?
git describe --all --match 'r[0-9]*' ... | sed ...
to map hashes etc. to these rNN-NNNN identifiers and something to map them
back to hashes say for git web?
