We should probably do a numeric comparison here, which may involve a smarter split than just splitting by '.' We should also probably consider going orange or something if the bump fails.

Manually bumped: https://hg.mozilla.org/releases/mozilla-beta/rev/a6edfa473c7dde50edc14a85374eb400e5ada494 Updating ship-it...

`map(int, re.split('\.|b', VERSION))` appears to do what we want. One caveat: it strips out the 'b' in a beta version. So 54.0b1 > 54.0, which is wrong. We need to detect alpha/beta versions and act appropriately. >>> import re >>> a = "54.0b9" >>> b = "54.0b10" >>> re.split('\.|b', a) ['54', '0', '9'] >>> re.split('\.|b', a) > re.split('\.|b', b) # this is a list of *strings* True >>> map(int, re.split('\.|b', a)) # list of ints, as we want [54, 0, 9] >>> map(int, re.split('\.|b', b)) [54, 0, 10] >>> map(int, re.split('\.|b', a)) > map(int, re.split('\.|b', b)) False

>>> from distutils.version import StrictVersion >>> StrictVersion(a) > StrictVersion(b) False >>> StrictVersion(a) < StrictVersion(b) True This is probably what we want.

For the record, ship-it had to use a custom child class of LooseVersion[1]. ESR was causing issues back then. [1] https://github.com/mozilla-releng/ship-it/pull/160/files#diff-f83f8d03a433676118af15e7221a5f2d

https://hg.mozilla.org/integration/mozilla-inbound/rev/043a52623b594840fe9a4059256a746cd5c98549 bug 1366916 - fix version bumping from b9 -> b10. r=mtabara

Landed on inbound, which means this should be fixed for 55.0b9->55.0b10. I don't *think* we'll hit an issue going from 54.0b10->54.0b11, so we should be good.
