Hi all,
I have a corrupted git repo.I've worked through the process
<https://git.wiki.kernel.org/index.php/GitFaq#How_to_fix_a_broken_repository.3F>
but still have some problem.
1- at the beginning, with "git fsck --full", it showed:
Checking object directories: 100% (256/256), done.
dangling blob 13dcdade560f11e8bc2d865a0d4a1a1133e5b132

dangling blob f61e50d30fa95683067aa2a50380e3dd7033e6dd

missing blob e187557d07857b974ea51e3ea962ac120cfc9488
2- since I don't have a "broken link" message,I use $ git commit -m "fixing
git repo",it said:

3- and then I use $ git hash-object -w project5/css/style.css, it said:
git hash-object -w project5/css/style.css

the result is not the missing blob

4- so I use $ git log --raw --all --full-history -- project5/css/style.css,
it said:

The above show you that the previous version of the blob was 595691a.
But in the output you showed there was no line with something like:
> :100644 100644 e187557... <newversion>... M project5/css/style.css
So we know the previous version but not the subsequent version of that file.
Could you check again that there is no subsequent version with something like:
git log --raw --all --full-history -- project5/css/style.css | grep e187557
?

You can use "git cat-file blob 595691a" to look at the previous version.

If "git hash-object -w <recreated-file>" results in
e187557d07857b974ea51e3ea962ac120cfc9488
then it means that the missing blob was successfully rewritten into
your git repo, so everything should be fine after that.
To make sure you can run "git fsck" again.
Note that you are trying to recreate the missing blob, but in my
opinion before trying to do that you should probably try to find the
missing blob in another repo. The log above showed that the missing
blob was created on the 15th of December (Sun Dec 15 23:40:39 2013
+0800). Haven't you pushed your repo somewhere since that day? If you
did push, it's probably easier to get the missing blob from where you
pushed.
Regards,
Christian.
