GIT-UPLOAD-PACK(1)                Git Manual                GIT-UPLOAD-PACK(1)

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[1] documentation and "HTTP
           Transport" in the Git Wire Protocol, Version 2[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.
