I was having the following issue while doing a “git push”:
$ git push Counting objects: 50, done. Compressing objects: 100% (33/33), done. Writing objects: 100% (36/36), 4.42 KiB, done. Total 36 (delta 13), reused 0 (delta 0) error: unable to write sha1 filename ./objects/fc/0bf175cf9bf2ecdf15eee84adad32230107aa7: Permission denied fatal: failed to write object error: unpack failed: unpacker exited with error code To firstname.lastname@example.org:/home/git/name-of-repo ! [remote rejected] master -> master (n/a (unpacker error)) error: failed to push some refs to 'email@example.com:/home/git/name-of-repo'
The issue turned out to be that because I’m using ssh + git to push the files, the files in the .git/objects directories are created with the user+group of the user on the host. So, the first user to create the file makes them with their own userid & groupid, and are set with default permissions as u=rxw,g=rx,o=rx, and thus, when the second user comes it to add a new file to that pre-existing subdirectory, they don’t have permissions.
I tried to solve this issue by creating “group git” and adding all users who are using the repository in /home/git/name-of-repo, but it still turns out that new files are created with userid:groupid as user:user not user:git.
How do you get around this issue? How do I make it so that new directories created by git during the push process are given the correct permissions (u=rxw,g=rxw,o=) and assigned to group git instead of the user group?
This issue is easy enough to fix manually, by doing something along the lines of:
$ ssh firstname.lastname@example.org (myhost.com)$ cd /home/git/name-of-repo/.git/objects (myhost.com)$ find . type d | xargs chgrp git (myhost.com)$ find . type d | xargs chmod g=rxw
But, I’m going to have to continue to do this as new directories in the “objects” area are going to continue to be created with the wrong permissions.
GIT HAS THE WORST ERROR MESSAGES IN ANY PIECE OF USER-FACING SOFTWARE I’VE EVER SEEN.
There, I said it. Peace out.
Just read about the git config setting “core.sharedRepository” which will automatically give group rwx permissions to newly created files in the repository. So, I ran:
$ git config --add core.sharedRepository group
