so i messed this up once and was gonna re-do it all but then i decided “… you know what this would be interesting to film”

for those of you who don’t know: Git does not distinguish between negative-0 and positive-0 offsets. but to pay homage to RFC 2822’s convention to use +0000 to represent a real timezone while -0000 to represent the lack of time zone i decided to re-write all commits i made on the VPS with -0000.

so to fix that minor slip-up i had to modify the rebase instruction format to do a crude find-and-replace of +0000 (i have never been anywhere near that European zone so any appearance of it must indicate a lack of timezone) in the commit object, then re-write it. but i should not touch the other branch that comes from upstream, since those are made by people much less pedantic than me and, in fact, use +0000 a lot. so git rebase wouldn’t cut it… and here we are.

(well, technically after that one big merge and the commits are all mine, i could technically do a git rebase -i <base> --rebase-merges of everything from there… but c’mon where’s the fun in that. besides, not every branch has to be rebased - just the direct descendants of the affected commit! :)

oh, and the rebase instruction is this by the way. don’t use it if you have +0000 in your commit message or your author/committer name, by the way – it’s not smart enough to distinguish those cases…

[rebase]
    instructionFormat = %s%nexec GIT_AUTHOR_DATE=\"%aI\" GIT_AUTHOR_NAME=\"%aN\" GIT_AUTHOR_EMAIL=\"%aE\" GIT_COMMITTER_DATE=\"%cI\" GIT_COMMITTER_NAME=\"%cN\" GIT_COMMITTER_EMAIL=\"%cE\" git commit --amend --reset-author --no-edit --cleanup=verbatim%nexec git update-ref HEAD $(git cat-file commit HEAD | sed s/+0000/-0000/ | git hash-object -t commit -w --stdin)%n
