Built a `git-recover-repository` command today. So far it only does the
|
|
detection and deletion of corrupt objects, and retrieves them from remotes
|
|
when possible. No handling yet of missing objects that cannot be recovered
|
|
from remotes.
|
|
|
|
Here's a couple of sample runs where I do bad things to the git
|
|
repository and it fixes them:
|
|
|
|
<pre>
|
|
joey@darkstar:~/tmp/git-annex>chmod 644 .git/objects/pack/*
|
|
joey@darkstar:~/tmp/git-annex>echo > .git/objects/pack/pack-a1a770c1569ac6e2746f85573adc59477b96ebc5.pack
|
|
joey@darkstar:~/tmp/git-annex>~/src/git-annex/git-recover-repository
|
|
Running git fsck ...
|
|
git fsck found a problem but no specific broken objects. Perhaps a corrupt pack file? Unpacking all pack files.
|
|
fatal: early EOF
|
|
Unpacking objects: 100% (148/148), done.
|
|
Unpacking objects: 100% (354/354), done.

|
Re-running git fsck to see if it finds more problems.

Successfully recovered repository!

You should run "git fsck" to make sure, but it looks like
|
|
everything was recovered ok.

</pre>

Works great! I need to move this and `git-union-merge` out of the git-annex
|
|
source tree sometime.
