# git-upload-pack(1) Manual Page

## NAME

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

## SYNOPSIS

    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 git-http-backend(1) to serve up `$GIT_URL/info/refs?service=git-upload-pack` requests. See "Smart Clients" in the HTTP transfer protocols documentation and "HTTP Transport" in the Git Wire Protocol, Version 2 documentation. Also understood by 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 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`.
