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

NAME         top

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

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

       --[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 git-http-backend(1) to serve up
           $GIT_URL/info/refs?service=git-upload-pack requests. See
           "Smart Clients" in gitprotocol-http(5) and "HTTP Transport" in
           the gitprotocol-v2(5) documentation. Also understood by
           git-receive-pack(1).

       <directory>
           The repository to sync from.

ENVIRONMENT         top

       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.

SECURITY         top

       Most Git commands should not be run in an untrusted .git directory
       (see the section SECURITY in 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' ...
