--- stage: none group: unassigned info: To determine the technical writer assigned to the Stage/Group associated with this page, see https://about.gitlab.com/handbook/product/ux/technical-writing/#assignments --- # Rake tasks for developers Rake tasks are available for developers and others contributing to GitLab. ## Set up database with developer seeds If your database user does not have advanced privileges, you must create the database manually before running this command. ```shell bundle exec rake setup ``` The `setup` task is an alias for `gitlab:setup`. This tasks calls `db:reset` to create the database, and calls `db:seed_fu` to seed the database. `db:setup` calls `db:seed` but this does nothing. ### Environment variables **MASS_INSERT**: Create millions of users (2m), projects (5m) and its relations. It's highly recommended to run the seed with it to catch slow queries while developing. Expect the process to take up to 20 extra minutes. See also [Mass inserting Rails models](mass_insert.md). **LARGE_PROJECTS**: Create large projects (through import) from a predefined set of URLs. ### Seeding issues for all or a given project You can seed issues for all or a given project with the `gitlab:seed:issues` task: ```shell # All projects bin/rake gitlab:seed:issues # A specific project bin/rake "gitlab:seed:issues[group-path/project-path]" ``` By default, this seeds an average of 2 issues per week for the last 5 weeks per project. #### Seeding issues for Insights charts **(ULTIMATE)** You can seed issues specifically for working with the [Insights charts](../user/group/insights/index.md) with the `gitlab:seed:insights:issues` task: ```shell # All projects bin/rake gitlab:seed:insights:issues # A specific project bin/rake "gitlab:seed:insights:issues[group-path/project-path]" ``` By default, this seeds an average of 10 issues per week for the last 52 weeks per project. All issues are also randomly labeled with team, type, severity, and priority. #### Seeding groups with subgroups You can seed groups with subgroups that contain milestones/projects/issues with the `gitlab:seed:group_seed` task: ```shell bin/rake "gitlab:seed:group_seed[subgroup_depth, username]" ``` Group are additionally seeded with epics if GitLab instance has epics feature available. #### Seeding a runner fleet test environment Use the `gitlab:seed:runner_fleet` task to seed a full runner fleet, specifically groups with subgroups and projects that contain runners and pipelines: ```shell bin/rake "gitlab:seed:runner_fleet[username, registration_prefix, runner_count, job_count]" ``` By default, the Rake task uses the `root` username to create 40 runners and 400 jobs. ```mermaid graph TD G1[Top level group 1] --> G11 G2[Top level group 2] --> G21 G11[Group 1.1] --> G111 G11[Group 1.1] --> G112 G111[Group 1.1.1] --> P1111 G112[Group 1.1.2] --> P1121 G21[Group 2.1] --> P211 P1111[Project 1.1.1.1

To import these metrics, you can run: ```shell bundle exec rake 'gitlab:seed:development_metrics[your_project_id]' ``` #### Seed a project with vulnerabilities You can seed a project with [security vulnerabilities](../user/application_security/vulnerabilities/index.md). ```shell # Seed all projects bin/rake 'gitlab:seed:vulnerabilities' # Seed a specific project bin/rake 'gitlab:seed:vulnerabilities[group-path/project-path]' ``` ### Automation If you're very sure that you want to **wipe the current database** and refill seeds, you can set the `FORCE` environment variable to `yes`: ```shell FORCE=yes bundle exec rake setup ``` This skips the action confirmation/safety check, saving 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`: ```shell echo 'yes' | bundle exec rake setup > /dev/null ``` Because 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. ### Extra Project seed options There are a few environment flags you can pass to change how projects are seeded - `SIZE`: defaults to `8`, max: `32`. Amount of projects to create. - `LARGE_PROJECTS`: defaults to false. If set, clones 6 large projects to help with testing. - `FORK`: defaults to false. If set to `true`, forks `torvalds/linux` five times. Can also be set to an existing project `full_path` to fork that instead. ## Run tests To run the test you can use the following commands: - `bin/rake spec` to run the RSpec suite - `bin/rake spec:unit` to run only the unit tests - `bin/rake spec:integration` to run only the integration tests - `bin/rake spec:system` to run only the system tests `bin/rake spec` takes significant time to pass. Instead of running the 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 a merge request, CI runs full test suite for you. Green CI status in the merge request means full test suite is passed. You can't run `rspec .` since this tries to run all the `_spec.rb` files it can find, also the ones in `/tmp` You can pass RSpec command line options to the `spec:unit`, `spec:integration`, and `spec:system` tasks. For example, `bin/rake "spec:unit[--tag ~geo --dry-run]"`. For an RSpec test, to run a single test file you can run: ```shell bin/rspec spec/controllers/commit_controller_spec.rb ``` To run several tests inside one directory: - `bin/rspec spec/requests/api/` for the RSpec tests if you want to test API only ### Run RSpec tests which failed in Merge Request pipeline on your machine If your Merge Request pipeline failed with RSpec test failures, you can run all the failed tests on your machine with the following Rake task: ```shell bin/rake spec:merge_request_rspec_failure ``` There are a few caveats for this Rake task: - You need to be on the same branch on your machine as the source branch of the Merge Request. - The pipeline must have been completed. - You may need to wait for the test report to be parsed and retry again. This Rake task depends on the [unit test reports](../ci/testing/unit_test_reports.md) feature, which only gets parsed when it is requested for the first time. ### Speed up tests, Rake tasks, and migrations [Spring](https://github.com/rails/spring) is a Rails application pre-loader. 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 must export the `ENABLE_SPRING` environment variable to `1`: ```shell export ENABLE_SPRING=1 ``` Alternatively you can use the following on each spec run, ```shell bundle exec spring rspec some_spec.rb ``` ## RuboCop tasks ## Generate initial RuboCop TODO list One way to generate the initial list is to run the Rake task `rubocop:todo:generate`: ```shell bundle exec rake rubocop:todo:generate ``` To generate TODO list for specific RuboCop rules, pass them comma-seperated as argument to the Rake task: ```shell bundle exec rake 'rubocop:todo:generate[Gitlab/NamespacedClass,Lint/Syntax]' bundle exec rake rubocop:todo:generate\[Gitlab/NamespacedClass,Lint/Syntax\] ``` Some shells require brackets to be escaped or quoted. See [Resolving RuboCop exceptions](../development/rubocop_development_guide.md#resolving-rubocop-exceptions) on how to proceed from here. ### Run RuboCop in graceful mode You can run RuboCop in "graceful mode". This means all enabled cop rules are silenced which have "grace period" activated (via `Details: grace period`). Run: ```shell bundle exec rake 'rubocop:check:graceful' bundle exec rake 'rubocop:check:graceful[Gitlab/NamespacedClass]' ``` ## 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: ```shell RAILS_ENV=production NODE_ENV=production bundle exec rake gitlab:assets:compile ``` This compiles and minifies 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. ## Emoji tasks To update the Emoji aliases file (used for Emoji autocomplete), run the following: ```shell bundle exec rake tanuki_emoji:aliases ``` To update the Emoji digests file (used for Emoji autocomplete), run the following: ```shell bundle exec rake tanuki_emoji:digests ``` This updates the file `fixtures/emojis/digests.json` based on the currently available Emoji. To generate a sprite file containing all the Emoji, run: ```shell bundle exec rake tanuki_emoji:sprite ``` If new emoji are added, the sprite sheet may change size. To compensate for such changes, first generate the `emoji.png` sprite sheet with the above Rake task, then check the dimensions of the new sprite sheet and update the `SPRITESHEET_WIDTH` and `SPRITESHEET_HEIGHT` constants accordingly. ## Update project templates Starting a project from a template needs this project to be exported. On a up to date main branch run: ```shell gdk start 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 main. To update just a single template instead of all of them, specify the template name between square brackets. For example, for the `cluster_management` template, run: ```shell bundle exec rake gitlab:update_project_templates\[cluster_management\] ``` ## Generate route lists To see the full list of API routes, you can run: ```shell bundle exec rake grape:path_helpers ``` The generated list includes a full list of API endpoints and functional RESTful API verbs. For the Rails controllers, run: ```shell bundle exec rails routes ``` Since these take some time to create, it's often helpful to save the output to a file for quick reference. ## Show obsolete `ignored_columns` To see a list of all obsolete `ignored_columns` run: ```shell bundle exec rake db:obsolete_ignored_columns ``` Feel free to remove their definitions from their `ignored_columns` definitions. ## Validate GraphQL queries To check the validity of one or more of our front-end GraphQL queries, run: ```shell # Validate all queries bundle exec rake gitlab:graphql:validate # Validate one query bundle exec rake gitlab:graphql:validate[path/to/query.graphql] # Validate a directory bundle exec rake gitlab:graphql:validate[path/to/queries] ``` This prints out a report with an entry for each query, explaining why each query is invalid if it fails to pass validation. We strip out `@client` fields during validation so it is important to mark client fields with the `@client` directive to avoid false positives. ## Analyze GraphQL queries Analogous to `ANALYZE` in SQL, we can run `gitlab:graphql:analyze` to estimate the of the cost of running a query. Usage: ```shell # Analyze all queries bundle exec rake gitlab:graphql:analyze # Analyze one query bundle exec rake gitlab:graphql:analyze[path/to/query.graphql] # Analyze a directory bundle exec rake gitlab:graphql:analyze[path/to/queries] ``` This prints out a report for each query, including the complexity of the query if it is valid. The complexity depends on the arguments in some cases, so the reported complexity is a best-effort assessment of the upper bound. ## Update GraphQL documentation and schema definitions To generate GraphQL documentation based on the GitLab schema, run: ```shell bundle exec rake gitlab:graphql:compile_docs ``` In its current state, the Rake task: - Generates output for GraphQL objects. - Places the output at `doc/api/graphql/reference/index.md`. This uses some features from `graphql-docs` gem like its schema parser and helper methods. The docs generator code comes from our side giving us more flexibility, like using Haml templates and generating Markdown files. To edit the content, you may need to edit the following: - The template. You can edit the template at `tooling/graphql/docs/templates/default.md.haml`. The actual renderer is at `Tooling::Graphql::Docs::Renderer`. - The applicable `description` field in the code, which [Updates machine-readable schema files](#update-machine-readable-schema-files), which is then used by the `rake` task described earlier. `@parsed_schema` is an instance variable that the `graphql-docs` gem expects to have available. `Gitlab::Graphql::Docs::Helper` defines the `object` method we currently use. This is also where you should implement any new methods for new types you'd like to display. ### Update machine-readable schema files To generate GraphQL schema files based on the GitLab schema, run: ```shell bundle exec rake gitlab:graphql:schema:dump ``` This uses GraphQL Ruby's built-in Rake tasks to generate files in both [IDL](https://www.prisma.io/blog/graphql-sdl-schema-definition-language-6755bcb9ce51) and JSON formats. ### Update documentation and schema definitions The following command combines the intent of [Update GraphQL documentation and schema definitions](#update-graphql-documentation-and-schema-definitions) and [Update machine-readable schema files](#update-machine-readable-schema-files): ```shell bundle exec rake gitlab:graphql:update_all ``` ## Update OpenAPI client for Error Tracking feature NOTE: This Rake task needs `docker` to be installed. To update generated code for OpenAPI client located in `vendor/gems/error_tracking_open_api` run the following commands: ```shell # Run rake task bundle exec rake gems:error_tracking_open_api:generate # Review and test the changes # Commit the changes git commit -m 'Update ErrorTrackingOpenAPI from OpenAPI definition' vendor/gems/error_tracking_open_api ``` ## Update banned SSH keys You can add [banned SSH keys](../security/ssh_keys_restrictions.md#block-banned-or-compromised-keys) from any Git repository by using the `gitlab:security:update_banned_ssh_keys` Rake task: 1. Find a public remote Git repository containing SSH public keys. The public key files must have the `.pub` file extension. 1. Make sure that `/tmp/` directory has enough space to store the remote Git repository. 1. To add the SSH keys to your banned-key list, run this command, replacing `GIT_URL` and `OUTPUT_FILE` with appropriate values: ```shell # @param git_url - Remote Git URL. # @param output_file - Update keys to an output file. Default is config/security/banned_ssh_keys.yml. bundle exec rake "gitlab:security:update_banned_ssh_keys[GIT_URL, OUTPUT_FILE]" ``` This task clones the remote repository, recursively walks the file system looking for files ending in `.pub`, parses those files as SSH public keys, and then adds the public key fingerprints to `output_file`. The contents of `config/security/banned_ssh_keys.yml` is read by GitLab and kept in memory. It is not recommended to increase the size of this file beyond 1 megabyte in size.
