    • Improve performance of the cycle analytics page. · ba25e2f1
      Timothy Andrew authored
      1. These changes bring down page load time for 100 issues from more than
         a minute to about 1.5 seconds.
      
      2. This entire commit is composed of these types of performance
         enhancements:
      
           - Cache relevant data in `IssueMetrics` wherever possible.
           - Cache relevant data in `MergeRequestMetrics` wherever possible.
           - Preload metrics
      
      3. Given these improvements, we now only need to make 4 SQL calls:
      
          - Load all issues
          - Load all merge requests
          - Load all metrics for the issues
          - Load all metrics for the merge requests
      
      4. A list of all the data points that are now being pre-calculated:
      
          a. The first time an issue is mentioned in a commit
      
            - In `GitPushService`, find all issues mentioned by the given commit
              using `ReferenceExtractor`. Set the `first_mentioned_in_commit_at`
              flag for each of them.
      
            - There seems to be a (pre-existing) bug here - files (and
              therefore commits) created using the Web CI don't have
              cross-references created, and issues are not closed even when
              the commit title is "Fixes #xx".
      
          b. The first time a merge request is deployed to production
      
            When a `Deployment` is created, find all merge requests that
            were merged in before the deployment, and set the
            `first_deployed_to_production_at` flag for each of them.
      
          c. The start / end time for a merge request pipeline
      
            Hook into the `Pipeline` state machine. When the `status` moves to
            `running`, find the merge requests whose tip commit matches the
            pipeline, and record the `latest_build_started_at` time for each
            of them. When the `status` moves to `success`, record the
            `latest_build_finished_at` time.
      
          d. The merge requests that close an issue
      
            - This was a big cause of the performance problems we were having
              with Cycle Analytics. We need to use `ReferenceExtractor` to make
              this calculation, which is slow when we have to run it on a large
              number of merge requests.
      
            - When a merge request is created, updated, or refreshed, find the
              issues it closes, and create an instance of
              `MergeRequestsClosingIssues`, which acts as a join model between
              merge requests and issues.
      
            - If a `MergeRequestsClosingIssues` instance links a merge request
              and an issue, that issue closes that merge request.
      
      5. The `Queries` module was changed into a class, so we can cache the
         results of `issues` and `merge_requests_closing_issues` across
         various cycle analytics stages.
      
      6. The code added in this commit is untested. Tests will be added in the
         next commit.

    • Enable RuboCop for migrations · 98bb435f
      Sean McGivern authored
      Migrations shouldn't fail RuboCop checks - especially lint checks, such
      as the nested method check. To avoid changing code in existing
      migrations, add the magic comment to the top of each of them to skip
      that file.
