Yeah, I saw that, and I think I know what's causing the problem. First I
create a bare mirror of AOSP with "repo init --mirror" and "repo sync", then
for all my different source trees I use "repo init --reference" to share
objects with the mirror using alternates files. Running "repo sync" on the
bare mirror works fine. The problem occurs when I run "repo sync" in one of
my source trees. Commits and refs have been deleted from the mirror, but the
refs are not deleted from the repos that point to the mirror. So it all
makes sense now. Still, I wish there were a simple command I could run to
remove the dangling refs.
Yep, that all makes sense.
As I said before, I don't think auto-deleting corrupted refs is great in
general, just because it can make a bad situation worse. But if you want
the foot-gun, here's a more complete script that you could run. It
_just_ looks in refs/remotes/, which is perhaps a bit safer.
git for-each-ref --format='%(refname)' refs/remotes/ |
git cat-file --batch-check='%(objectname)' |
perl -alne 'print "delete $F[0]" if $F[1] eq "missing"' |
tee /dev/stderr |
git update-ref --stdin

Thanks. Here's what I have been using:
git fsck |& grep "invalid sha1 pointer" | (
while read err ref rest
do
ref=${ref%:}
echo got $ref, removing .git/$ref
rm .git/$ref
done
)
