      Added & use Gitlab::Routing for URL helpers · e9f14a22e0b2
      Yorick Peterse authored
      Rails' "url_helpers" method creates an anonymous Module (which a bunch
      of methods) on every call. By caching the output of this method in a
      dedicated method we can shave off about 10 seconds of loading time for
      an issue with around 200 comments.

      Greatly improve external_issue_tracker performance · b231f73002ef
      Yorick Peterse authored
      This greatly improves the performance of Project#external_issue_tracker
      by moving most of the fields queried in Ruby to the database and letting
      the database handle all logic. Prior to this change the process of
      finding an external issue tracker was along the lines of the following:
      
      1. Load all project services into memory.
      2. Reduce the list to only services where "issue_tracker?" returns true
      3. Reduce the list from step 2 to service where "default?" returns false
      4. Find the first service where "activated?" returns true
      
      This has to two big problems:
      
      1. Loading all services into memory only to reduce the list down to a
         single item later on is a waste of memory (and slow timing wise).
      2. Calling Array#select followed by Array#reject followed by Array#find
         allocates extra objects when this really isn't needed.
      
      To work around this the following service fields have been moved to the
      database (instead of being hardcoded):
      
      * category
      * default
      
      This in turn means we can get the external issue tracker using the
      following query:
      
          SELECT *
          FROM services
          WHERE active IS TRUE
          AND default IS FALSE
          AND category = 'issue_tracker'
          AND project_id = XXX
          LIMIT 1
      
      This coupled with memoizing the result (just as before this commit)
      greatly reduces the time it takes for Project#external_issue_tracker to
      complete. The exact reduction depends on one's environment, but locally
      the execution time is reduced from roughly 230 ms to only 2 ms (= a
      reduction of almost 180x).
      
      Fixes gitlab-org/gitlab-ce#10771
