git‐remote‐ext − Bridge smart transport to external command.



git remote add <nick> "ext::<command>[ <arguments>...]"




This remote helper uses the specified <command> to connect
to a remote Git server.

Data written to stdin of the specified <command> is assumed
to be sent to a git:// server, git−upload−pack,
git−receive−pack or git−upload−archive (depending on
situation), and data read from stdout of <command> is
assumed to be received from the same service.

Command and arguments are separated by an unescaped space.

The following sequences have a special meaning:

     '% '
     Literal space in command or argument.

     %%
     Literal percent sign.

     %s
     Replaced with name (receive−pack, upload−pack, or
     upload−archive) of the service Git wants to invoke.

     %S
     Replaced with long name (git−receive−pack,
     git−upload−pack, or git−upload−archive) of the service
     Git wants to invoke.

     %G (must be the first characters in an argument)
     This argument will not be passed to <command>. Instead,
     it will cause the helper to start by sending git://
     service requests to the remote side with the service
     field set to an appropriate value and the repository
     field set to rest of the argument. Default is not to
     send such a request.

     This is useful if remote side is git:// server accessed
     over some tunnel.

     %V (must be first characters in argument)
     This argument will not be passed to <command>. Instead
     it sets the vhost field in the git:// service request
     (to rest of the argument). Default is not to send vhost
     in such request (if sent).

     GIT_TRANSLOOP_DEBUG
     If set, prints debugging information about various
     reads/writes.



     GIT_EXT_SERVICE
     Set to long name (git−upload−pack, etc...) of service
     helper needs to invoke.

     GIT_EXT_SERVICE_NOPREFIX
     Set to long name (upload−pack, etc...) of service
     helper needs to invoke.



This remote helper is transparently used by Git when you use
commands such as "git fetch <URL>", "git clone <URL>", ,
"git push <URL>" or "git remote add <nick> <URL>", where
<URL> begins with ext::. Examples:

     "ext::ssh −i /home/foo/.ssh/somekey user@host.example
%S foo/repo"
     Like host.example:foo/repo, but use
     /home/foo/.ssh/somekey as keypair and user as user on
     remote side. This avoids needing to edit .ssh/config.

     "ext::socat −t3600 − ABSTRACT−CONNECT:/git−server
%G/somerepo"
     Represents repository with path /somerepo accessible
     over git protocol at abstract namespace address
     /git−server.

     "ext::git−server−alias foo %G/repo"
     Represents a repository with path /repo accessed using
     the helper program "git−server−alias foo". The path to
     the repository and type of request are not passed on
     the command line but as part of the protocol stream, as
     usual with git:// protocol.

     "ext::git−server−alias foo %G/repo %Vfoo"
     Represents a repository with path /repo accessed using
     the helper program "git−server−alias foo". The hostname
     for the remote server passed in the protocol stream
     will be "foo" (this allows multiple virtual Git servers
     to share a link−level address).

     "ext::git−server−alias foo %G/repo% with% spaces %Vfoo"
     Represents a repository with path /repo with spaces
     accessed using the helper program "git−server−alias
     foo". The hostname for the remote server passed in the
     protocol stream will be "foo" (this allows multiple









                             ‐3‐


     virtual Git servers to share a link−level address).

     "ext::git−ssl foo.example /bar"
     Represents a repository accessed using the helper
     program "git−ssl foo.example /bar". The type of request
     can be determined by the helper using environment
     variables (see above).
