git-http-backend

I tried to set up a git server with git-http-backend and everything works pretty much as I want but there is one little thing.

The config

<VirtualHost *:80>
ServerName git.server.com
SetEnv GIT_PROJECT_ROOT /srv/git
SetEnv GIT_HTTP_EXPORT_ALL
SetEnv REMOTE_USER=$REDIRECT_REMOTE_USER
ScriptAlias /git /usr/lib/git-core/git-http-backend/

<Directory "/usr/lib/git-core*">
   Options ExecCGI Indexes
   Order allow,deny
   Allow from all
</Directory>

<LocationMatch "^/git/repos/git-receive-pack$">
  AuthType Digest
  AuthName "Git Repositories"
  AuthUserFile /srv/git/.git-auth-file
  AuthGroupFile /srv/git/.git-group-file
  Require valid-user
</LocationMatch>
</VirtualHost>

This allows everybody to read the repos but only valid users to write. The thing that bugs me is that the url is http://git.server.com/git/repos. I would like to get rid of the git in the URL like http://git.server.com/repos. When I change the config to

<VirtualHost *:80>
ServerName git.server.com
SetEnv GIT_PROJECT_ROOT /srv/git
SetEnv GIT_HTTP_EXPORT_ALL
SetEnv REMOTE_USER=$REDIRECT_REMOTE_USER
ScriptAlias / /usr/lib/git-core/git-http-backend/

<Directory "/usr/lib/git-core*">
   Options ExecCGI Indexes
   Order allow,deny
   Allow from all
</Directory>

<LocationMatch "^/repos/git-receive-pack$">
  AuthType Digest
  AuthName "Git Repositories"
  AuthUserFile /srv/git/.git-auth-file
  AuthGroupFile /srv/git/.git-group-file
  Require valid-user
</LocationMatch>
</VirtualHost>

The authentication fails. I can still read the repos but git push fails. I couldn't figure out why this happens.

Can someone help me understand why the latter fails? I assume it must be that the ScriptAlias kicks in during the authentication.

EDIT 1 The logging of apache didn't give me much information. Just that the authentication fail for some reason.

The access_log says:

MYIP - - [29/Aug/2011:19:03:18 +0200] "GET /repos/info/refs?service=git-receive-pack HTTP/1.1" 200 153
MYIP - - [29/Aug/2011:19:03:18 +0200] "POST /repos/git-receive-pack HTTP/1.1" 404 - 

and the error_log says:

[Mon Aug 29 19:03:18 2011] [error] [client MYIP] Request not supported:   '/srv/git/error/HTTP_UNAUTHORIZED.html.var'

I don't have a 100% sure fire answer, but check out my question about GIT here, Setting up Git Server on Windows With git-http-backend.exe.

My locationMatch is slightly different, but not by much:

<LocationMatch "^/repositories/.*/git-upload-pack$">
    Options +ExecCGI
    AuthType Basic
    AuthName intranet
    AuthUserFile "C:/GIT/Apache/config/users"
    AuthGroupFile "C:/GIT/Apache/config/groups"
    Require group committers
</LocationMatch>

The url I would use would be myserver.com/repositories/mytest.git

Hope this helps.


Try changing

ScriptAlias / /usr/lib/git-core/git-http-backend/

to a more intelligent match that only directs git requests to git-http-backend:

ScriptAliasMatch \
    "(?x)^/(.*/(HEAD | \
                    info/refs | \
                    objects/(info/[^/]+ | \
                             [0-9a-f]{2}/[0-9a-f]{38} | \
                             pack/pack-[0-9a-f]{40}\.(pack|idx)) | \
                             git-(upload|receive)-pack))$" \
     /usr/lib/git-core/git-http-backend/
