Rake tasks for developers

Setup db with developer seeds

Note that if your db user does not have advanced privileges you must create the db manually before running this command.

bundle exec rake setup

The setup task is an alias for gitlab:setup. This tasks calls db:reset to create the database, calls add_limits_mysql that adds limits to the database schema in case of a MySQL database and finally it calls db:seed_fu to seed the database. Note: db:setup calls db:seed but this does nothing.

Automation

If you're very sure that you want to wipe the current database and refill seeds, you could:

echo 'yes' | bundle exec rake setup

To save you from answering yes manually.

Discard stdout

Since the script would print a lot of information, it could be slowing down your terminal, and it would generate more than 20G logs if you just redirect it to a file. If we don't care about the output, we could just redirect it to /dev/null:

echo 'yes' | bundle exec rake setup > /dev/null

Note that since you can't see the questions from stdout, you might just want to echo 'yes' to keep it running. It would still print the errors on stderr so no worries about missing errors.

Notes for MySQL

Since the seeds would contain various UTF-8 characters, such as emojis or so, we'll need to make sure that we're using utf8mb4 for all the encoding settings and utf8mb4_unicode_ci for collation. Please check MySQL utf8mb4 support

Make sure that config/database.yml has encoding: utf8mb4, too.

Next, we'll need to update the schema to make the indices fit:

sed -i 's/limit: 255/limit: 191/g' db/schema.rb

Then run the setup script:

bundle exec rake setup

To make sure that indices still fit. You could find great details in: How to support full Unicode in MySQL databases

Run tests

In order to run the test you can use the following commands:

  • rake spec to run the rspec suite
  • rake karma to run the karma test suite
  • rake gitlab:test to run all the tests

Note: rake spec takes significant time to pass. Instead of running full test suite locally you can save a lot of time by running a single test or directory related to your changes. After you submit merge request CI will run full test suite for you. Green CI status in the merge request means full test suite is passed.

Note: You can't run rspec . since this will try to run all the _spec.rb files it can find, also the ones in /tmp

To run a single test file you can use:

  • bin/rspec spec/controllers/commit_controller_spec.rb for a rspec test

To run several tests inside one directory:

  • bin/rspec spec/requests/api/ for the rspec tests if you want to test API only

Speed-up tests, rake tasks, and migrations

Spring is a Rails application preloader. It speeds up development by keeping your application running in the background so you don't need to boot it every time you run a test, rake task or migration.

If you want to use it, you'll need to export the ENABLE_SPRING environment variable to 1:

export ENABLE_SPRING=1

Alternatively you can use the following on each spec run,

bundle exec spring rspec some_spec.rb

Compile Frontend Assets

You shouldn't ever need to compile frontend assets manually in development, but if you ever need to test how the assets get compiled in a production environment you can do so with the following command:

RAILS_ENV=production NODE_ENV=production bundle exec rake gitlab:assets:compile

This will compile and minify all JavaScript and CSS assets and copy them along with all other frontend assets (images, fonts, etc) into /public/assets where they can be easily inspected.

Generate API documentation for project services (e.g. Slack)

bundle exec rake services:doc

Updating Emoji Aliases

To update the Emoji aliases file (used for Emoji autocomplete) you must run the following:

bundle exec rake gemojione:aliases

Updating Emoji Digests

To update the Emoji digests file (used for Emoji autocomplete) you must run the following:

bundle exec rake gemojione:digests

This will update the file fixtures/emojis/digests.json based on the currently available Emoji.

Emoji Sprites

Generating a sprite file containing all the Emoji can be done by running:

bundle exec rake gemojione:sprite

If new emoji are added, the spritesheet may change size. To compensate for such changes, first generate the emoji.png spritesheet with the above Rake task, then check the dimensions of the new spritesheet and update the SPRITESHEET_WIDTH and SPRITESHEET_HEIGHT constants accordingly.

Updating project templates

Starting a project from a template needs this project to be exported. On a up to date master branch with run:

gdk run
# In a new terminal window
bundle exec rake gitlab:update_project_templates
git checkout -b update-project-templates
git add vendor/project_templates
git commit
git push -u origin update-project-templates

Now create a merge request and merge that to master.

Generate route lists

To see the full list of API routes, you can run:

bundle exec rake grape:path_helpers

For the Rails controllers, run:

bundle exec rake routes

Since these take some time to create, it's often helpful to save the output to a file for quick reference.
