I have been asked to add a hook script to some SVN repositories. The repositories run under Apache with the mod_dav_svn
module.
Do I need to restart Apache in order that the hook is picked up or will it Just Work from the moment the file is there and executable?
No. SVN-hooks aren't Apache side of game, it's pure Subversion toys, thus - create and use immediately on svn-events
I believe it should happen immediately. No apache restart required.
