NAME¶
git-remote-ext - Bridge smart transport to external command.
SYNOPSIS¶
git remote add <nick> "ext::<command>[ <arguments>...]"
DESCRIPTION¶
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).
ENVIRONMENT VARIABLES¶
GIT_TRANSLOOP_DEBUG
If set, prints debugging information about various
reads/writes.
ENVIRONMENT VARIABLES PASSED TO COMMAND¶
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.
EXAMPLES¶
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 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).
