## 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)](https://www.chedong.com/phpMan.php/man/git-http-backend/1/markdown) to serve up **$GIT**___**URL/info/refs?service=git-upload-pack**
           requests. See "Smart Clients" in **the** **HTTP** **transfer** **protocols**[1] documentation and "HTTP
           Transport" in **the** **Git** **Wire** **Protocol,** **Version** **2**[2] documentation. Also understood by **git-**
           [**receive-pack**(1)](https://www.chedong.com/phpMan.php/man/receive-pack/1/markdown).

       <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)](https://www.chedong.com/phpMan.php/man/git/1/markdown).

       **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**.
