git-daemon - A really simple server for git repositories.
A really simple TCP git daemon that normally listens on port "DEFAULT_GIT_PORT" aka 9418. It waits for a connection, and will just execute "git-upload-pack" when it gets one.
It's careful in that there's a magic request-line that gives the command and what directory to upload, and it verifies that the directory is ok.
It verifies that the directory has the magic file "git-daemon-export-ok", and it will refuse to export any git directory that hasn't explicitly been marked for export this way (unless the --export-all parameter is specified). If you pass some directory paths as git-daemon arguments, you can further restrict the offers to a whitelist comprising of those.
This is ideally suited for read-only updates, ie pulling from git repositories.
Match paths exactly (i.e. don't allow "/foo/repo" when the real path is "/foo/repo.git" or "/foo/repo/.git") and don't do user-relative paths. git-daemon will refuse to start when this option is enabled and no whitelist is specified.
Remap all the path requests as relative to the given path. This is sort of "GIT root" - if you run git-daemon with --base-path=/srv/git on example.com, then if you later try to pull git://example.com/hello.git, git-daemon will interpret the path as /srv/git/hello.git.
Allow pulling from all directories that look like GIT repositories (have the objects and refs subdirectories), even if they do not have the git-daemon-export-ok file.
Have the server run as an inetd service. Implies --syslog.
Listen on an alternative port.
Timeout between the moment the connection is established and the client request is received (typically a rather low value, since that should be basically immediate).
Timeout for specific client sub-requests. This includes the time it takes for the server to process the sub-request and time spent waiting for next client's request.
Log to syslog instead of stderr. Note that this option does not imply --verbose, thus by default only error conditions will be logged.
Allow ~user notation to be used in requests. When specified with no parameter, requests to git://host/~alice/foo is taken as a request to access foo repository in the home directory of user alice. If --user-path=path is specified, the same request is taken as a request to access path/foo repository in the home directory of user alice.
Log details about the incoming connections and requested files.
A directory to add to the whitelist of allowed directories. Unless --strict-paths is specified this will also include subdirectories of each named directory.
