+ # Htgroup accesses apache-compatible group files. Htgroup can be used to
+ # provide group-based authentication for users. Currently Htgroup is not
+ # directly integrated with any authenticators in WEBrick. For security,
+ # the path for a digest password database should be stored outside of the
+ # paths available to the HTTP server.
+ #
+ # Example:
+ #
+ # htgroup = WEBrick::HTTPAuth::Htgroup.new 'my_group_file'
+ # htgroup.add 'superheroes', %w[spiderman batman]
+ #
+ # htgroup.members('superheroes').include? 'magneto' # => false
+
+ class Htgroup

+ # Open a group database at +path+
+

+ @path = path
+ @mtime = Time.at(0)
+ @group = Hash.new
+ open(@path,"a").close unless File::exist?(@path)
+ reload
+ end
+
+ ##
+ # Reload groups from the database
+
+ def reload
+ if (mtime = File::mtime(@path)) > @mtime
+ @group.clear
+ open(@path){|io|
+ while line = io.gets
+ line.chomp!
+ group, members = line.split(/:\s*/)
+ @group[group] = members.split(/\s+/)
+ end
+ }
+ @mtime = mtime

+ # Flush the group database. If +output+ is given the database will be
+ # written there instead of to the original path.
