1git-receive-pack(1) 2=================== 3v0.1, July 2005 4 5NAME 6---- 7git-receive-pack - Receive what is pushed into it 8 9 10SYNOPSIS 11-------- 12'git-receive-pack' <directory> 13 14DESCRIPTION 15----------- 16Invoked by 'git-send-pack' and updates the repository with the 17information fed from the remote end. 18 19This command is usually not invoked directly by the end user. 20The UI for the protocol is on the 'git-send-pack' side, and the 21program pair is meant to be used to push updates to remote 22repository. For pull operations, see 'git-fetch-pack' and 23'git-clone-pack'. 24 25The command allows for creation and fast forwarding of sha1 refs 26(heads/tags) on the remote end (strictly speaking, it is the 27local end receive-pack runs, but to the user who is sitting at 28the send-pack end, it is updating the remote. Confused?) 29 30Before each ref is updated, if $GIT_DIR/hooks/update file exists 31and executable, it is called with three parameters: 32 33 $GIT_DIR/hooks/update refname sha1-old sha1-new 34 35The refname parameter is relative to $GIT_DIR; e.g. for the 36master head this is "refs/heads/master". Two sha1 are the 37object names for the refname before and after the update. Note 38that the hook is called before the refname is updated, so either 39sha1-old is 0{40} (meaning there is no such ref yet), or it 40should match what is recorded in refname. 41 42The hook should exit with non-zero status if it wants to 43disallow updating the named ref. Otherwise it should exit with 44zero. 45 46Using this hook, it is easy to generate mails on updates to 47the local repository. This example script sends a mail with 48the commits pushed to the repository: 49 50 #!/bin/sh 51 # mail out commit update information. 52 if expr "$2" : '0*$' >/dev/null 53 then 54 echo "Created a new ref, with the following commits:" 55 git-rev-list --pretty "$2" 56 else 57 echo "New commits:" 58 git-rev-list --pretty "$3" "^$2" 59 fi | 60 mail -s "Changes to ref $1" commit-list@mydomain 61 exit 0 62 63Another hook $GIT_DIR/hooks/post-update, if exists and 64executable, is called with the list of refs that have been 65updated. This can be used to implement repository wide cleanup 66task if needed. The exit code from this hook invocation is 67ignored; the only thing left for git-receive-pack to do at that 68point is to exit itself anyway. This hook can be used, for 69example, to run "git-update-server-info" if the repository is 70packed and is served via a dumb transport. 71 72 #!/bin/sh 73 exec git-update-server-info 74 75OPTIONS 76------- 77<directory>:: 78 The repository to sync into. 79 80 81SEE ALSO 82-------- 83link:git-send-pack.html[git-send-pack] 84 85 86Author 87------ 88Written by Linus Torvalds <torvalds@osdl.org> 89 90Documentation 91-------------- 92Documentation by Junio C Hamano. 93 94GIT 95--- 96Part of the link:git.html[git] suite
