问题
I was happily using Git - made some commits a couple of nights ago, which are reflected in the remote repo. Last night I opened up Smartgit Hg and it tells me there are missing trees. I ran git fsck --full and got the rather large output below.
I'm a Git amateur. I use a GUI to do what I need to do. I've tried reading through this (https://git.wiki.kernel.org/index.php/GitFaq#How_to_fix_a_broken_repository.3F) but it isn't making an awful lot of sense and following it blindly doesn't seem to be working.
I did a git ls-tree c957fc03bb53181547142045917211fbc380a8df and it shows me a list of files. I had 3 with a 100644 at the beginning, so I moved in to that directory, ran git hash-object -w filename and it output the same hash as the ls-tree showed me.
The wiki page says now I'm all done. Except git fsck --full still shows the same message for that tree. I get the feeling that I'm probably running these commands on the wrong thing.
I've tried reading other git posts on here, but they don't make sense to me. I won't lie.
git fsck --full

回答1:
Try cloning the remote repository into a new folder.
Does it also have these errors? If not, simply use this clone and delete the corrupted one.
Any modified files that have not yet been committed can simple be copied to the new folder. Important: Don't copy the .git folder.
回答2:
For me, a simple git gc did the job... This gave me a couple of rm: cannot unlink ... Permission denied messages. But in the end, it seemed to have worked for my case.
Bug probably depends on how exactly the repo is corrupted.
