This allows a helper to say that, when it handles "import refs/heads/topic", the script it outputs will actually write to refs/svn/origin/branches/topic; therefore, transport-helper should read it from the latter location after git-fast-import completes.

NAME
|
|
----
|
|
git-remote-helpers - Helper programs for interoperation with remote git
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git remote-<transport>' <remote>
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
These programs are normally not used directly by end users, but are
|
|
invoked by various git programs that interact with remote repositories
|
|
when the repository they would operate on will be accessed using
|
|
transport code not linked into the main git binary. Various particular
|
|
helper programs will behave as documented here.
|
|
|
|
COMMANDS
|
|
--------
|
|
|
|
Commands are given by the caller on the helper's standard input, one per line.
|
|
|
|
'capabilities'::
|
|
Lists the capabilities of the helper, one per line, ending
|
|
with a blank line.
|
|
|
|
'list'::
|
|
Lists the refs, one per line, in the format "<value> <name>
|
|
[<attr> ...]". The value may be a hex sha1 hash, "@<dest>" for
|
|
a symref, or "?" to indicate that the helper could not get the
|
|
value of the ref. A space-separated list of attributes follows
|
|
the name; unrecognized attributes are ignored. After the
|
|
complete list, outputs a blank line.
|
|
|
|
'fetch' <sha1> <name>::
|
|
Fetches the given object, writing the necessary objects to the
|
|
database. Outputs a blank line when the fetch is
|
|
complete. Only objects which were reported in the ref list
|
|
with a sha1 may be fetched this way.
|
|
+
|
|
Supported if the helper has the "fetch" capability.
|
|
|
|
'import' <name>::
|
|
Produces a fast-import stream which imports the current value
|
|
of the named ref. It may additionally import other refs as
|
|
needed to construct the history efficiently. The script writes
|
|
to a helper-specific private namespace. The value of the named
|
|
ref should be written to a location in this namespace derived
|
|
by applying the refspecs from the "refspec" capability to the
|
|
name of the ref.
|
|
+
|
|
Supported if the helper has the "import" capability.
|
|
|
|
If a fatal error occurs, the program writes the error message to
|
|
stderr and exits. The caller should expect that a suitable error
|
|
message has been printed if the child closes the connection without
|
|
completing a valid response for the current command.
|
|
|
|
Additional commands may be supported, as may be determined from
|
|
capabilities reported by the helper.
|
|
|
|
CAPABILITIES
|
|
------------
|
|
|
|
'fetch'::
|
|
This helper supports the 'fetch' command.
|
|
|
|
'import'::
|
|
This helper supports the 'import' command.
|
|
|
|
'refspec' 'spec'::
|
|
When using the import command, expect the source ref to have
|
|
been written to the destination ref. The earliest applicable
|
|
refspec takes precedence. For example
|
|
"refs/heads/*:refs/svn/origin/branches/*" means that, after an
|
|
"import refs/heads/name", the script has written to
|
|
refs/svn/origin/branches/name. If this capability is used at
|
|
all, it must cover all refs reported by the list command; if
|
|
it is not used, it is effectively "*:*"
|
|
|
|
REF LIST ATTRIBUTES

None are defined yet, but the caller must accept any which are supplied.
