Hi, all.
We have a repo on a corporate server. The sysadmin changed access
rights of files on our repo by accedant.
Some directories have 2750 acces rights before, but he changed as
chmod -R 2770 *
Now when you make git status, every file that is tracked by git is said as
changed but not updated
So is there a way to get this back to normal ?
TIA

If so, then here's what I would do: 1. First make a copy of your repo and test these steps on the copy: e.g. bare repo: cp -rvp repo.git repocopy.git non-bare-repo: cp -rvp worktree worktreecopy 2. Then cd to the parent of the objects dir in you git repo: e.g. bare repo: cd repocopy.git non-bare repo: cd worktreecopy/.git 3. Then change the permissions of your objects dir: chmod -R 2750 objects 4. Validate the results. Your permissions should match again. 5. If it worked, then do it on the real repo. v/r, Neal ^ permalink raw reply [flat|nested] 6+ messages in thread

Please let me know if you know of an easier/better way to do this. Change Permissions on an Existing Git Repo: Check System for Users who may be using the Repo: # w (see who's logged in) # ps -A |grep git-menu-scriptname (where scriptname is some unique string in the name of the main script your users use to access that repo, if applicable) # skill -KILL pts/99 (where 99 = the pts/# from w command, log the user off) Change Shared=group to Shared=0644 (change group read+write to group read only): Create Template for permissions: login as fsngit0 $ cd /path/to/template $ cat config [core] sharedRepository = 0644 Clone repo to set permissions via git: $ cd /path/to/repo-parent-dir $ git clone --bare --template=/path/to/template file:///path/to/REPO.git REPOMOD.git Compare old and new versions: $ diff -r REPO.git REPOMOD.git Only in REPO.git: branches (empty, keep the old version) diff -r REPO.git/config REPOMOD.git/config (merge the old and new together) 1a2 > sharedrepository = 0644 6,7c7 < denyDeletes = true < denyNonFastForwards = true --- > denyNonFastforwards = true Only in REPO.git: description (keep the old version) Only in REPO.git: gitk.cache (gitk will recreate this) Only in REPO.git: hooks (contains sample scripts only or whatever scripts your using, keep the old version) Only in REPO.git: info (keep the old version: contains attributes, exclude, or whatever you've setup) Only in REPO.git/objects: aa (keep new version, loose object have been packed) Only in REPO.git/objects/pack: pack-A5735e9b894dce1498ec1c776dcabc97fd8ceAfc.idx diff -r REPO.git/packed-refs REPOMOD.git/packed-refs (keep the new version because fresh clone has been optimized) 2c2 < Xa8b7b8c8fd3920b89770f2e8356f4ecb71a58cX refs/heads/master --- > Ya69744e46276a37932d5f0755a53f76cdf83e0dY refs/heads/master Only in REPO.git/refs/heads: master (old version not needed because fresh clone has been optimized) Copy over REPO.git files that the clone didn't replicate, but that you need in order to retain all settings: $ cp -rv /path/to/REPO.git/info . repeat as needed... change permissions to g-w or whatever your core.sharedRepository new value is supposed to be: $ chmod -R g-w info repeat as needed...
