When +`git-init-db` is run, a handful example hooks are copied in the +`hooks` directory of the new repository, but by default they are +all disabled. To enable a hook, make it executable with `chmod ++x`. + +This document describes the currently defined hooks. + +applypatch-msg +-------------- + +This hook is invoked by `git-applypatch` script, which is +typically invoked by `git-applymbox`. It takes a single +parameter, the name of the file that holds the proposed commit +log message. Exiting with non-zero status causes the +'git-applypatch' to abort before applying the patch. + +The hook is allowed to edit the message file in place, and can +be used to normalize the message into some project standard +format (if the project has one). It can also be used to refuse +the commit after inspecting the message file. + +The default applypatch-msg hook, when enabled, runs the +commit-msg hook, if the latter is enabled. + +pre-applypatch +-------------- + +This hook is invoked by `git-applypatch` script, which is +typically invoked by `git-applymbox`. It takes no parameter, +and is invoked after the patch is applied, but before a commit +is made. Exiting with non-zero status causes the working tree +after application of the patch not committed. + +It can be used to inspect the current working tree and refuse to +make a commit if it does not pass certain test. + +The default pre-applypatch hook, when enabled, runs the +pre-commit hook, if the latter is enabled. + +post-applypatch +--------------- + +This hook is invoked by `git-applypatch` script, which is +typically invoked by `git-applymbox`. It takes no parameter, +and is invoked after the patch is applied and a commit is made. + +This hook is meant primarily for notification, and cannot affect +the outcome of `git-applypatch`. + +pre-commit +---------- + +This hook is invoked by `git-commit-script`, and can be bypassed +with `--no-verify` option. It takes no parameter, and is +invoked before obtaining the proposed commit log message and +making a commit. Exiting with non-zero status from this script +causes the `git-commit-script` to abort. + +The default pre-commit hook, when enabled, catches introduction +of lines with trailing whitespaces and aborts the commit when +a such line is found. + +commit-msg +---------- + +This hook is invoked by `git-commit-script`, and can be bypassed +with `--no-verify` option. It takes a single parameter, the +name of the file that holds the proposed commit log message. +Exiting with non-zero status causes the `git-commit-script` to +abort. + +The hook is allowed to edit the message file in place, and can +be used to normalize the message into some project standard +format (if the project has one). It can also be used to refuse +the commit after inspecting the message file. + +The default commit-msg hook, when enabled, detects duplicate +Signed-off-by: lines, and aborts the commit when one is found. + +post-commit +----------- + +This hook is invoked by `git-commit-script`. It takes no +parameter, and is invoked after a commit is made. + +This hook is meant primarily for notification, and cannot affect +the outcome of `git-commit-script`. + +The default post-commit hook, when enabled, demonstrates how to +send out a commit notification e-mail. + +update +------ + +This hook is invoked by `git-receive-pack`, which is invoked +when a `git push` is done against the repository. It takes +three parameters, name of the ref being updated, old object name +stored in the ref, and the new objectname to be stored in the +ref. Exiting with non-zero status from this hook prevents +`git-receive-pack` from updating the ref. + +This can be used to prevent 'forced' update on certain refs by +making sure that the object name is a commit object that is a +descendant of the commit object named by the old object name. +Another use suggested on the mailing list is to use this hook to +implement access control which is finer grained than the one +based on filesystem group. + +post-update +----------- + +This hook is invoked by `git-receive-pack`, which is invoked +when a `git push` is done against the repository. It takes +variable number of parameters; each of which is the name of ref +that was actually updated. + +This hook is meant primarily for notification, and cannot affect +the outcome of `git-receive-pack`. + +The default post-update hook, when enabled, runs +`git-update-server-info` to keep the information used by dumb +transport up-to-date. -- 2.47.1
