A sudden lack of permission

A sudden lack of permission

[Ivan Uemlianin]

  Dear All

I have been using git quite happily for a good while, pushing to my 
remote.  Suddenly this afternoon the remote told me I didn't have 
permission:

     $ git push
     ivan@remote.org's password:
     Counting objects: 19, done.
     Delta compression using up to 2 threads.
     Compressing objects: 100% (11/11), done.
     Writing objects: 100% (11/11), 1.04 KiB, done.
     Total 11 (delta 8), reused 0 (delta 0)
     error: insufficient permission for adding an object to repository 
database ./objects

     fatal: failed to write object
     error: unpack failed: unpack-objects abnormal exit
     To ivan@remote.org:/var/www/git/my_repos.git
      ! [remote rejected] master -> master (n/a (unpacker error))
     error: failed to push some refs to 
'ivan@remote.org:/var/www/git/my_repos.git'

I had sufficient permission even this morning!

Please could someone tell me what might have happened and, more 
importantly, how I can start pushing to the remote again?  The project 
in my_repos is large, so I'd rather not start a new repos from scratch.

With thanks and best wishes

Ivan

Presumably the permissions on the server changed for some reason. Can
you ssh to the remote host and confirm that user "ivan" has permissions
to write to the repo's objects dir? If not, then you will have to figure
out what happened, but it is likely outside the scope of git (e.g., an
overly inclusive chmod by some cron job or admin on the box).

If you do have permissions, then we will have to dig deeper into why git
would fail, but the permissions would appear fine.

  Dear Peff

Thanks for your help.

Yes, I can ssh onto the server, cd to /var/www/git/my_repos.git and add, 
edit files, etc.

There is another person on the box doing sysadmin.  I'll ask.

Is there any reason the repos could have just broken somehow?  A corrupt 
push?

Best wishes

Ivan

Did you check specifically the /var/www/git/my_repos.git/objects
directory?

I can't imagine a corrupt push would do it. Git shouldn't be changing
the permissions on the objects directory at all.

I can add files to the objects directory, but files in subdirectories 
(eg ff/, info/, pack/) are read only.

I have tried pushing to other reposes on the same server and some I can 
push to some I can't.  Ones I /can/ push to, their objects/ff/ etc 
directories are read only.

I'm using git a lot, but as (a) it generally just works and (b) I'm 
doing very basic things (pull, push, add, commit, status), I know very 
little about what is really going on.

Best wishes

Ivan
