git-upload-pack(1)
==================

NAME
----
git-upload-pack - Send objects packed back to git-fetch-pack


SYNOPSIS
--------
[verse]
'git-upload-pack' [--[no-]strict] [--timeout=<n>] [--stateless-rpc]
		  [--advertise-refs] <directory>

DESCRIPTION
-----------
Invoked by 'git fetch-pack', learns what
objects the other side is missing, and sends them after packing.

This command is usually not invoked directly by the end user.
The UI for the protocol is on the 'git fetch-pack' side, and the
program pair is meant to be used to pull updates from a remote
repository.  For push operations, see 'git send-pack'.

OPTIONS
-------

--[no-]strict::
	Do not try <directory>/.git/ if <directory> is no Git directory.

--timeout=<n>::
	Interrupt transfer after <n> seconds of inactivity.

--stateless-rpc::
	Perform only a single read-write cycle with stdin and stdout.
	This fits with the HTTP POST request processing model where
	a program may read the request, write a response, and must exit.

--http-backend-info-refs::
	Used by linkgit:git-http-backend[1] to serve up
	`$GIT_URL/info/refs?service=git-upload-pack` requests. See
	"Smart Clients" in link:technical/http-protocol.html[the HTTP
	transfer protocols] documentation and "HTTP Transport" in
	link:technical/protocol-v2.html[the Git Wire Protocol, Version
	2] documentation. Also understood by
	linkgit:git-receive-pack[1].

<directory>::
	The repository to sync from.

ENVIRONMENT
-----------

`GIT_PROTOCOL`::
	Internal variable used for handshaking the wire protocol. Server
	admins may need to configure some transports to allow this
	variable to be passed. See the discussion in linkgit:git[1].

`GIT_NO_LAZY_FETCH`::
	When cloning or fetching from a partial repository (i.e., one
	itself cloned with `--filter`), the server-side `upload-pack`
	may need to fetch extra objects from its upstream in order to
	complete the request. By default, `upload-pack` will refuse to
	perform such a lazy fetch, because `git fetch` may run arbitrary
	commands specified in configuration and hooks of the source
	repository (and `upload-pack` tries to be safe to run even in
	untrusted `.git` directories).
+
This is implemented by having `upload-pack` internally set the
`GIT_NO_LAZY_FETCH` variable to `1`. If you want to override it
(because you are fetching from a partial clone, and you are sure
you trust it), you can explicitly set `GIT_NO_LAZY_FETCH` to
`0`.
