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. |

Requirements
Please see the requirements documentation for system requirements and more information about the supported operating systems.
Installation
The recommended way to install GitLab is with the Omnibus packages on our package server. Compared to an installation from source, this is faster and less error prone. Just select your operating system, download the respective package (Debian or RPM) and install it using the system's package manager.
There are various other options to install GitLab, please refer to the installation page on the GitLab website for more information.
You can access a new installation with the login root
and password 5iveL!fe
, after login you are required to set a unique password.
Install a development environment
To work on GitLab itself, we recommend setting up your development environment with the GitLab Development Kit. If you do not use the GitLab Development Kit you need to install and setup all the dependencies yourself, this is a lot of work and error prone. One small thing you also have to do when installing it yourself is to copy the example development unicorn configuration file:
cp config/unicorn.rb.example.development config/unicorn.rb
Instructions on how to start GitLab and how to run the tests can be found in the development section of the GitLab Development Kit.
Software stack
GitLab is a Ruby on Rails application that runs on the following software:
- Ubuntu/Debian/CentOS/RHEL
- Ruby (MRI) 2.3
- Git 2.7.4+
- Redis 2.8+
- MySQL or PostgreSQL
For more information please see the architecture documentation.
Third-party applications
There are a lot of third-party applications integrating with GitLab. These include GUI Git clients, mobile applications and API wrappers for various languages.
GitLab release cycle
For more information about the release process see the release documentation.
Upgrading
For upgrading information please see our update page.
Documentation
All documentation can be found on doc.gitlab.com/ce/.
