This index is added on `(target_project_id, iid)` and has a `WHERE state
= 'opened'` condition. Using this index we can drastically improve the
performance of the query used to count the total number of merge
requests in a group. Without this index the query would eventually
perform the following:
-> Index Scan using index_merge_requests_on_target_project_id_and_iid on merge_requests (cost=0.43..4.89 rows=7 width=4) (actual time=0.058..0.353 rows=6 loops=228)
Index Cond: (target_project_id = projects.id)
Filter: ((state)::text = 'opened'::text)
Rows Removed by Filter: 141
Buffers: shared hit=34351 dirtied=1
Out of the ~180 milliseconds the entire query would take, around 170
milliseconds was spent in just this segment. With the index in place,
the above segment is turned into the following:
-> Index Only Scan using yorick_test on merge_requests (cost=0.42..0.55 rows=7 width=4) (actual time=0.004..0.010 rows=6 loops=228)
Index Cond: (target_project_id = projects.id)
Heap Fetches: 419
Buffers: shared hit=1381
The index also reduces the total query time to roughly 10 milliseconds.

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 getting started 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/OpenSUSE
- Ruby (MRI) 2.3
- Git 2.8.4+
- Redis 2.8+
- PostgreSQL (preferred) or MySQL
For more information please see the architecture documentation.
UX design
Please adhere to the UX Guide when creating designs and implementing code.
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.
