Ok, here is one day in the life of messing about with git.
Let's say you wanted to get rid of all history from a repo, just keep
the current commit. Git lets us rewrite history, so this should be
easy, right? Wrong. I won't tell you how long it took to find this
weird technique:
#!/bin/sh -e
new_root_hash=`git rev-parse HEAD`
echo "$new_root_hash" >.git/info/grafts
git filter-branch -f
rm .git/info/grafts
At least it runs quickly.
Let's say you want to garbage collect your repo after getting rid of
that unwanted history...
git gc
whoops, it does not work.
final hacky 'solution' (after quite some research and experiment):
#!/bin/sh -ev
git remote rm origin || true
git for-each-ref --format="%(refname)" refs/original/ | xargs -n1
--no-run-if-empty git update-ref -d
(
cd .git
rm -rf refs/remotes/ refs/original/ *_HEAD logs/
)
git -c gc.reflogExpire=0 -c gc.reflogExpireUnreachable=0 -c
gc.rerereresolved=0 -c gc.rerereunresolved=0 -c gc.pruneExpire=now gc "$@"
But ordinary things are famously weird in git, also.
