The operations a helper supports are declared to git in the response
to the `capabilities` command (see COMMANDS, below).
-'option'::
- For specifying settings like `verbosity` (how much output to
- write to stderr) and `depth` (how much history is wanted in the
- case of a shallow clone) that affect how other commands are
- carried out.
-
-'connect'::
- For fetching and pushing using git's native packfile protocol
- that requires a bidirectional, full-duplex connection.
-
-'push'::
- For listing remote refs and pushing specified objects from the
- local object store to remote refs.
-
-'fetch'::
- For listing remote refs and fetching the associated history to
- the local object store.
-
-'export'::
- For listing remote refs and pushing specified objects from a
- fast-import stream to remote refs.
-
-'import'::
- For listing remote refs and fetching the associated history as
- a fast-import stream.
-
-'refspec' <refspec>::
- This modifies the 'import' capability, allowing the produced
- fast-import stream to modify refs in a private namespace
- instead of writing to refs/heads or refs/remotes directly.
- It is recommended that all importers providing the 'import'
- capability use this.
-+
-A helper advertising the capability
-`refspec refs/heads/*:refs/svn/origin/branches/*`
-is saying that, when it is asked to `import refs/heads/topic`, the
-stream it outputs will update the `refs/svn/origin/branches/topic`
-ref.
-+
-This capability can be advertised multiple times. The first
-applicable refspec takes precedence. The left-hand of refspecs
-advertised with this capability must cover all refs reported by
-the list command. If no 'refspec' capability is advertised,
-there is an implied `refspec *:*`.
-
-'bidi-import'::
- The fast-import commands 'cat-blob' and 'ls' can be used by remote-helpers
- to retrieve information about blobs and trees that already exist in
- fast-import's memory. This requires a channel from fast-import to the
- remote-helper.
- If it is advertised in addition to "import", git establishes a pipe from
- fast-import to the remote-helper's stdin.
- It follows that git and fast-import are both connected to the
- remote-helper's stdin. Because git can send multiple commands to
- the remote-helper it is required that helpers that use 'bidi-import'
- buffer all 'import' commands of a batch before sending data to fast-import.
- This is to prevent mixing commands and fast-import responses on the
- helper's stdin.
-
-'export-marks' <file>::
- This modifies the 'export' capability, instructing git to dump the
- internal marks table to <file> when complete. For details,
- read up on '--export-marks=<file>' in linkgit:git-fast-export[1].
-
-'import-marks' <file>::
- This modifies the 'export' capability, instructing git to load the
- marks specified in <file> before processing any input. For details,
- read up on '--import-marks=<file>' in linkgit:git-fast-export[1].
+In the following, we list all defined capabilities and for
+each we list which commands a helper with that capability
+must provide.
Capabilities for Pushing
-~~~~~~~~~~~~~~~~~~~~~~~~
+^^^^^^^^^^^^^^^^^^^^^^^^
'connect'::
Can attempt to connect to 'git receive-pack' (for pushing),
- 'git upload-pack', etc for communication using the
- packfile protocol.
+ 'git upload-pack', etc for communication using
+ git's native packfile protocol. This
+ requires a bidirectional, full-duplex connection.
+
Supported commands: 'connect'.
Capabilities for Fetching
-~~~~~~~~~~~~~~~~~~~~~~~~~
+^^^^^^^^^^^^^^^^^^^^^^^^^
'connect'::
Can try to connect to 'git upload-pack' (for fetching),
'git receive-pack', etc for communication using the
- packfile protocol.
+ git's native packfile protocol. This
+ requires a bidirectional, full-duplex connection.
+
Supported commands: 'connect'.
When choosing between 'fetch' and 'import', git prefers 'fetch'.
Other frontends may have some other order of preference.
+Miscellaneous capabilities
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+'option'::
+ For specifying settings like `verbosity` (how much output to
+ write to stderr) and `depth` (how much history is wanted in the
