Yeah, that's exactly what happened! :/ > So I guess this change could be quite useful, but it really needs some > documentation and tests to support it - git-p4 is already complicated > enough! Great, thanks for positive feedback. Let me start working on these. Luckily, the actual git-p4 changes are fairly straightforward. > Your example script should probably use the same magic that the git-p4 > script uses to pick the path to Python. Oh, you mean "#!/usr/bin/env python"? Sure! Actually, I also have a smarter "example script", which reconstructs `p4 describe` output from `p4 files` and `p4 change` without manual intervention. It's still short enough to be posted inside commit message, but would it make sense to put it under contrib/ and reference from the docs? > And perhaps come up with a nicer name than "damaged" - as you say, it > could also be used for other purposes. Does anything from the list below sound reasonable? 1. git-p4.loadChangelistInfo 2. git-p4.changelistInfoOverride 3. git-p4.cachedChangelistInfo >> For simplicity, it's one pickled file per changelist. (talking to myself) I realized `p4 -G describe` produces a marshalled output, not pickled one. Don't know why I decided to use pickle instead of marshal back when I wrote it. I'll switch to marshal for serialization/deserialization in the next reroll. It'll be easier for testing as well, since `p4 -G describe` output could be fed directly to damagedChangelists machinery without the need to convert it from marshal to pickle. Thank you, Andrey
