7 git-receive-pack - Receive what is pushed into it
12 'git-receive-pack' <directory>
16 Invoked by 'git-send-pack' and updates the repository with the
17 information fed from the remote end.
19 This command is usually not invoked directly by the end user.
20 The UI for the protocol is on the 'git-send-pack' side, and the
21 program pair is meant to be used to push updates to remote
22 repository. For pull operations, see 'git-fetch-pack' and
25 The command allows for creation and fast forwarding of sha1 refs
26 (heads/tags) on the remote end (strictly speaking, it is the
27 local end receive-pack runs, but to the user who is sitting at
28 the send-pack end, it is updating the remote. Confused?)
30 Before each ref is updated, if $GIT_DIR/hooks/update file exists
31 and executable, it is called with three parameters:
33 $GIT_DIR/hooks/update refname sha1-old sha1-new
35 The refname parameter is relative to $GIT_DIR; e.g. for the
36 master head this is "refs/heads/master". Two sha1 are the
37 object names for the refname before and after the update. Note
38 that the hook is called before the refname is updated, so either
39 sha1-old is 0{40} (meaning there is no such ref yet), or it
40 should match what is recorded in refname.
42 The hook should exit with non-zero status if it wants to
43 disallow updating the named ref. Otherwise it should exit with
46 Using this hook, it is easy to generate mails on updates to
47 the local repository. This example script sends a mail with
48 the commits pushed to the repository:
51 # mail out commit update information.
52 if expr "$2" : '0*$' >/dev/null
54 echo "Created a new ref, with the following commits:"
55 git-rev-list --pretty "$2"
58 git-rev-list --pretty "$3" "^$2"
60 mail -s "Changes to ref $1" commit-list@mydomain
63 Another hook $GIT_DIR/hooks/post-update, if exists and
64 executable, is called with the list of refs that have been
65 updated. This can be used to implement repository wide cleanup
66 task if needed. The exit code from this hook invocation is
67 ignored; the only thing left for git-receive-pack to do at that
68 point is to exit itself anyway. This hook can be used, for
69 example, to run "git-update-server-info" if the repository is
70 packed and is served via a dumb transport.
