      Cache the number of forks of a project · 970143440d40
      Yorick Peterse authored
      The number of forks of a project doesn't change very frequently and
      running a COUNT(*) every time this information is requested can be quite
      expensive. We also end up running such a COUNT(*) query at least twice
      on the homepage of a project.
      By caching this data and refreshing it when necessary we can reduce
      project homepage loading times by around 60 milliseconds (based on the
      timings of https://gitlab.com/gitlab-org/gitlab-ce).

      Use CTEs for nested groups and authorizations · f63dad32f25f
      Yorick Peterse authored
      This commit introduces the usage of Common Table Expressions (CTEs) to
      efficiently retrieve nested group hierarchies, without having to rely on
      the "routes" table (which is an _incredibly_ inefficient way of getting
      the data). This requires a patch to ActiveRecord (found in the added
      initializer) to work properly as ActiveRecord doesn't support WITH
      statements properly out of the box.
      Unfortunately MySQL provides no efficient way of getting nested groups.
      For example, the old routes setup could easily take 5-10 seconds
      depending on the amount of "routes" in a database. Providing vastly
      different logic for both MySQL and PostgreSQL will negatively impact the
      development process. Because of this the various nested groups related
      methods return empty relations when used in combination with MySQL.
      For project authorizations the logic is split up into two classes:
      * Gitlab::ProjectAuthorizations::WithNestedGroups
      * Gitlab::ProjectAuthorizations::WithoutNestedGroups
      Both classes get the fresh project authorizations (= as they should be
      in the "project_authorizations" table), including nested groups if
      PostgreSQL is used. The logic of these two classes is quite different
      apart from their public interface. This complicates development a bit,
      but unfortunately there is no way around this.
      This commit also introduces Gitlab::GroupHierarchy. This class can be
      used to get the ancestors and descendants of a base relation, or both by
      using a UNION. This in turn is used by methods such as:
      * Namespace#ancestors
      * Namespace#descendants
      * User#all_expanded_groups
      Again this class relies on CTEs and thus only works on PostgreSQL. The
      Namespace methods will return an empty relation when MySQL is used,
      while User#all_expanded_groups will return only the groups a user is a
      direct member of.
      Performance wise the impact is quite large. For example, on GitLab.com
      Namespace#descendants used to take around 580 ms to retrieve data for a
      particular user. Using CTEs we are able to reduce this down to roughly 1
      millisecond, returning the exact same data.
      == On The Fly Refreshing
      Refreshing of authorizations on the fly (= when
      users.authorized_projects_populated was not set) is removed with this
      commit. This simplifies the code, and ensures any queries used for
      authorizations are not mutated because they are executed in a Rails
      scope (e.g. Project.visible_to_user).
      This commit includes a migration to schedule refreshing authorizations
      for all users, ensuring all of them have their authorizations in place.
      Said migration schedules users in batches of 5000, with 5 minutes
      between every batch to smear the load around a bit.
      == Spec Changes
      This commit also introduces some changes to various specs. For example,
      some specs for ProjectTeam assumed that creating a personal project
      would _not_ lead to the owner having access, which is incorrect. Because
      we also no longer refresh authorizations on the fly for new users some
      code had to be added to the "empty_project" factory. This chunk of code
      ensures that the owner's permissions are refreshed after creating the
      project, something that is normally done in Projects::CreateService.

      Implement `json_response` as a `let` variable · 183e356e40a1
      Rémy Coutable authored
      This is not a good idea to memoize `json_response` using an instance
      variable because `rspec-retry` doesn't clear instance variables on
      retries, only `let` variables.
      This will avoid issues where retries would fail on a different line that
      the original failure, blurrying what's the real failure.
      Also, automatically add api: true to specs under
      /spec/requests/(ci/)?api/, and include JsonHelpers in controller, request
      and API specs.

      Fix all tests · 93f518a5f81c
      Toon Claes authored
      This commit was about 6 commits before squashing, with the main goal to
      make all tests green. Now, after pushing this commit we'll see what the
      CI has to say about that.
