Such a push by default is refused if the working +tree and the index of the remote repository has any difference from +the currently checked out commit; when both the working tree and the +index match the current commit, they are updated to match the newly +pushed tip of the branch. This hook is to be used to override the +default behaviour. + +The hook receives the commit with which the tip of the current +branch is going to be updated. It can exit with a non-zero status +to refuse the push (when it does so, it must not modify the index or +the working tree). Or it can make any necessary changes to the +working tree and to the index to bring them to the desired state +when the tip of the current branch is updated to the new commit, and +exit with a zero status. + +For example, the hook can simply run `git read-tree -u -m HEAD "$1"` +in order to emulate 'git fetch' that is run in the reverse direction +with `git push`, as the two-tree form of `read-tree -u -m` is +essentially the same as `git checkout` that switches branches while +keeping the local changes in the working tree that do not interfere +with the difference between the branches. + + pre-auto-gc ~~~~~~~~~~~ |
