==================

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 not a 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 linkgit:gitprotocol-http[5] and "HTTP
|
|
Transport" in the linkgit:gitprotocol-v2[5]
|
|
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`.
|
|
|
|
SECURITY
|
|
--------
|
|
|
|
Most Git commands should not be run in an untrusted `.git` directory
|
|
(see the section `SECURITY` in linkgit:git[1]). `upload-pack` tries to
|
|
avoid any dangerous configuration options or hooks from the repository
|
|
it's serving, making it safe to clone an untrusted directory and run
|
|
commands on the resulting clone.
|
|
|
|
For an extra level of safety, you may be able to run `upload-pack` as an
|
|
alternate user. The details will be platform dependent, but on many
|
|
systems you can run:
|
|
|
|
git clone --no-local --upload-pack='sudo -u nobody git-upload-pack' ...
