The workflow assumed here is: * Once a topic branch forks from "master", "master" is never merged into it again (either directly or indirectly). * Once a topic branch is fully cooked and merged into "master", it is deleted. If you need to build on top of it to correct earlier mistakes, a new topic branch is created by forking at the tip of the "master". This is not strictly necessary, but it makes it easier to keep your history simple. * Whenever you need to test or publish your changes to topic branches, merge them into "next" branch. The script, being an example, hardcodes the publish branch name to be "next", but it is trivial to make it configurable via $GIT_DIR/config mechanism. With this workflow, you would want to know: (1) ... if a topic branch has ever been merged to "next". Young topic branches can have stupid mistakes you would rather clean up before publishing, and things that have not been merged into other branches can be easily rebased without affecting other people. But once it is published, you would not want to rewind it. (2) ... if a topic branch has been fully merged to "master". Then you can delete it. More importantly, you should not build on top of it -- other people may already want to change things related to the topic as patches against your "master", so if you need further changes, it is better to fork the topic (perhaps with the same name) afresh from the tip of "master". Let's look at this example: o---o---o---o---o---o---o---o---o---o "next" / / / / / a---a---b A / / / / / / / / c---c---c---c B / / / / \ / / / / b---b C \ / / / / / \ / ---o---o---o---o---o---o---o---o---o---o---o "master" A, B and C are topic branches. * A has one fix since it was merged up to "next". * B has finished. It has been fully merged up to "master" and "next", and is ready to be deleted. * C has not merged to "next" at all. We would want to allow C to be rebased, refuse A, and encourage B to be deleted. To compute (1): git rev-list ^master ^topic next git rev-list ^master next if these match, topic has not merged in next at all. To compute (2): git rev-list master..topic if this is empty, it is fully merged to "master".

If we exit with a non-zero exit value then the update for that particular ref is denied, but updates for other refs in the same run of receive-pack may still be allowed. We are run after the objects have been uploaded, but before the ref is actually modified. We take advantage of that fact when we look for "new" commits and tags (the new objects won't show up in `rev-list --all`). This script loads and parses the content of the config file "users/$this_user.acl" from the $acl_branch commit of $acl_git ODB. The acl file is a git-config style file, but uses a slightly more restricted syntax as the Perl parser contained within this script is not nearly as permissive as git-config. Example: [user] committer = John Doe committer = John R. Doe [repository "acls"] allow = heads/master allow = CDUR for heads/jd/ allow = C for ^tags/v\\d+$ For all new commit or tag objects the committer (or tagger) line within the object must exactly match one of the user.committer values listed in the acl file ("HEAD:users/$this_user.acl"). For a branch to be modified an allow line within the matching repository section must be matched for both the refname and the opcode. Repository sections are matched on the basename of the repository (after removing the .git suffix). The opcode abbreviations are: C: create new ref D: delete existing ref U: fast-forward existing ref (no commit loss) R: rewind/rebase existing ref (commit loss) if no opcodes are listed before the "for" keyword then "U" (for fast-forward update only) is assumed as this is the most common usage. Refnames are matched by always assuming a prefix of "refs/". This hook forbids pushing or deleting anything not under "refs/". Refnames that start with ^ are Perl regular expressions, and the ^ is kept as part of the regexp. \\ is needed to get just one \, so \\d expands to \d in Perl. The 3rd allow line above is an example. Refnames that don't start with ^ but that end with / are prefix matches (2nd allow line above); all other refnames are strict equality matches (1st allow line). Anything pushed to "heads/" (ok, really "refs/heads/") must be a commit. Tags are not permitted here. Anything pushed to "tags/" (err, really "refs/tags/") must be an annotated tag. Commits, blobs, trees, etc. are not permitted here. Annotated tag signatures aren't checked, nor are they required. The special subrepository of 'info/new-commit-check' can be created and used to allow users to push new commits and tags from another local repository to this one, even if they aren't the committer/tagger of those objects. In a nut shell the info/new-commit-check directory is a Git repository whose objects/info/alternates file lists this repository and all other possible sources, and whose refs subdirectory contains symlinks to this repository's refs subdirectory, and to all other possible sources refs subdirectories.

There # is another script, git-multimail, which is more capable and # configurable and is largely backwards-compatible with this script; # please see "contrib/hooks/multimail/". For instructions on how to # migrate from post-receive-email to git-multimail, please see # "README.migrate-from-post-receive-email" in that directory. # # This hook sends emails listing new revisions to the repository # introduced by the change being reported. The rule is that (for # branch updates) each commit will appear on one email and one email # only. # # This hook is stored in the contrib/hooks directory. Your distribution # will have put this somewhere standard. You should make this script # executable then link to it in the repository you would like to use it in. # For example, on debian the hook is stored in # /usr/share/git-core/contrib/hooks/post-receive-email: # # cd /path/to/your/repository.git # ln -sf /usr/share/git-core/contrib/hooks/post-receive-email hooks/post-receive # # This hook script assumes it is enabled on the central repository of a # project, with all users pushing only to it and not between each other. It # will still work if you don't operate in that style, but it would become # possible for the email to be from someone other than the person doing the # push. # # To help with debugging and use on pre-v1.5.1 git servers, this script will # also obey the interface of hooks/update, taking its arguments on the # command line. Unfortunately, hooks/update is called once for each ref. # To avoid firing one email per ref, this script just prints its output to # the screen when used in this mode. The output can then be redirected if # wanted. # # Config # ------ # hooks.mailinglist # This is the list that all pushes will go to; leave it blank to not send # emails for every ref update. # hooks.announcelist # This is the list that all pushes of annotated tags will go to. Leave it # blank to default to the mailinglist field. The announce emails lists # the short log summary of the changes since the last annotated tag. # hooks.envelopesender # If set then the -f option is passed to sendmail to allow the envelope # sender address to be set # hooks.emailprefix # All emails have their subjects prefixed with this prefix, or "[SCM]" # if emailprefix is unset, to aid filtering # hooks.showrev # The shell command used to format each revision in the email, with # "%s" replaced with the commit id. Defaults to "git rev-list -1 # --pretty %s", displaying the commit id, author, date and log # message. To list full patches separated by a blank line, you # could set this to "git show -C %s; echo". # To list a gitweb/cgit URL *and* a full patch for each change set, use this: # "t=%s; printf 'http://.../?id=%%s' \$t; echo;echo; git show -C \$t; echo" # Be careful if "..." contains things that will be expanded by shell "eval" # or printf. # hooks.emailmaxlines # The maximum number of lines that should be included in the generated # email body.

So, we can't simply say rev-list $oldrev..$newrev. # Instead we find the common base of the two revs and list from # there. # # As above, we need to take into account the presence of X; if # another branch is already in the repository and points at some of # the revisions that we are about to output - we don't want them. # The solution is as before: git rev-parse output filtered. # # Finally, tags: 1 --- 2 --- O --- T --- 3 --- 4 --- N # # Tags pushed into the repository generate nice shortlog emails that # summarise the commits between them and the previous tag. However, # those emails don't include the full commit messages that we output # for a branch update.
