NAME
     git-receive-pack - Receive what is pushed into the
     repository

SYNOPSIS
     git-receive-pack <directory>


DESCRIPTION
     Invoked by git send-pack and updates the repository with the
     information fed from the remote end.

     This command is usually not invoked directly by the end
     user. The UI for the protocol is on the git send-pack side,
     and the program pair is meant to be used to push updates to
     remote repository. For pull operations, see git-fetch-
     pack(1).

     The command allows for creation and fast-forwarding of sha1
     refs (heads/tags) on the remote end (strictly speaking, it
     is the local end git-receive-pack runs, but to the user who
     is sitting at the send-pack end, it is updating the remote.
     Confused?)

     There are other real-world examples of using update and
     post-update hooks found in the Documentation/howto
     directory.

     git-receive-pack honours the receive.denyNonFastForwards
     config option, which tells it if updates to a ref should be
     denied if they are not fast-forwards.

OPTIONS
     <directory>
         The repository to sync into.

PRE-RECEIVE HOOK
     Before any ref is updated, if $GIT_DIR/hooks/pre-receive
     file exists and is executable, it will be invoked once with
     no parameters. The standard input of the hook will be one
     line per ref to be updated:

         sha1-old SP sha1-new SP refname LF

     The refname value is relative to $GIT_DIR; e.g. for the
     master head this is "refs/heads/master". The two sha1 values
     before each refname are the object names for the refname
     before and after the update. Refs to be created will have
     sha1-old equal to 0{40}, while refs to be deleted will have
     sha1-new equal to 0{40}, otherwise sha1-old and sha1-new
     should be valid objects in the repository.

     This hook is called before any refname is updated and before
     any fast-forward checks are performed.

     If the pre-receive hook exits with a non-zero exit status no
     updates will be performed, and the update, post-receive and
     post-update hooks will not be invoked either. This can be
     useful to quickly bail out if the update is not to be
     supported.

UPDATE HOOK
     Before each ref is updated, if $GIT_DIR/hooks/update file
     exists and is executable, it is invoked once per ref, with
     three parameters:

         $GIT_DIR/hooks/update refname sha1-old sha1-new

     The refname parameter is relative to $GIT_DIR; e.g. for the
     master head this is "refs/heads/master". The two sha1
     arguments are the object names for the refname before and
     after the update. Note that the hook is called before the
     refname is updated, so either sha1-old is 0{40} (meaning
     there is no such ref yet), or it should match what is
     recorded in refname.

     The hook should exit with non-zero status if it wants to
     disallow updating the named ref. Otherwise it should exit
     with zero.

     Successful execution (a zero exit status) of this hook does
     not ensure the ref will actually be updated, it is only a
     prerequisite. As such it is not a good idea to send notices
     (e.g. email) from this hook. Consider using the post-receive
     hook instead.

POST-RECEIVE HOOK
     After all refs were updated (or attempted to be updated), if
     any ref update was successful, and if
     $GIT_DIR/hooks/post-receive file exists and is executable,
     it will be invoked once with no parameters. The standard
     input of the hook will be one line for each successfully
     updated ref:

         sha1-old SP sha1-new SP refname LF

     The refname value is relative to $GIT_DIR; e.g. for the
     master head this is "refs/heads/master". The two sha1 values
     before each refname are the object names for the refname
     before and after the update. Refs that were created will
     have sha1-old equal to 0{40}, while refs that were deleted
     will have sha1-new equal to 0{40}, otherwise sha1-old and
     sha1-new should be valid objects in the repository.

     Using this hook, it is easy to generate mails describing the
     updates to the repository. This example script sends one
     mail message per ref listing the commits pushed to the
     repository:

         #!/bin/sh
         # mail out commit update information.
         while read oval nval ref
         do
                 if expr "$oval" : '0*$' >/dev/null
                 then
                         echo "Created a new ref, with the following commits:"
                         git rev-list --pretty "$nval"
                 else
                         echo "New commits:"
                         git rev-list --pretty "$nval" "^$oval"
                 fi |
                 mail -s "Changes to ref $ref" commit-list@mydomain
         done
         exit 0

     The exit code from this hook invocation is ignored, however
     a non-zero exit code will generate an error message.

     Note that it is possible for refname to not have sha1-new
     when this hook runs. This can easily occur if another user
     modifies the ref after it was updated by git-receive-pack,
     but before the hook was able to evaluate it. It is
     recommended that hooks rely on sha1-new rather than the
     current value of refname.

POST-UPDATE HOOK
     After all other processing, if at least one ref was updated,
     and if $GIT_DIR/hooks/post-update file exists and is
     executable, then post-update will be called with the list of
     refs that have been updated. This can be used to implement
     any repository wide cleanup tasks.

     The exit code from this hook invocation is ignored; the only
     thing left for git-receive-pack to do at that point is to
     exit itself anyway.

     This hook can be used, for example, to run git
     update-server-info if the repository is packed and is served
     via a dumb transport.

         #!/bin/sh
         exec git update-server-info
