Subject: [PATCH] Adding hooks.directory config option; wiring into run_hook
The new hooks.directory config option allows each git repository to
specify the location of the hooks for that repository. The default
remains $GIT_DIR/hooks. The ability to change the hooks directory is
necessary when stuck in an environment with enhanced security and
trusted path execution policies. These systems require that any file
that can be executed exhibit at least the following characteristics:
* The executable, it's directory, and each directory above it are
not writable.
Since the hooks directory is within a directory that by it's very nature
requires write permissions, hooks are a non-starter in git's current
state. This patch aims to allow a (most likely bare) repo to have it's
hooks directory customized to a location that meets the above
requirements.
I'm not terribly good at C++, so please let me know if I need to fix
anything. I saw that there were a bunch of scripts that have
GIT_DIR/hooks hard-coded in them. Since I'm not familiar with those
scripts, I will leave them alone for now. Maybe someone that is familiar
with the scripts can integrate the new configuration option into them?
