Hello list, I don't know if this is the right place to report a bug, but I'll just try and see what comes back. I am trying to build a Wiki [1] using PHP, a hacked version of Markdown, and git for content tracking. I use the git core plumbing to do the history work. The PHP script created directories under .git/objects
Ouch... You're not really supposed to do that. The proper thing to do is to do things in the working tree and commit them to git later.
which were only writable by www-data. There were other directories which were owned by user mk and group www-data, and they were group writable. So, I had write access to only a part of the .git directory.
Unless you're using the git tools (or things hooking in to the git core C functions somehow), don't touch the .git directory.
(this merits an exclamation marks, so brace yourselves) !
When I tried to commit, I got a message saying "Unable to write sha1 filename".
What file were you trying to write?
The result was, that only part of the commit was recorded and that I experienced repository corruption. refs/heads/master pointed to a non-existant object.
Did you use git tools to update .git/refs/heads/master ?
The expected behavior would have been an error message telling me I had insufficient write privileges and surely no repository corruption.
Didn't you get the strerror(3) message from that? If so, I'd consider it a bug.
