If set, the [`Elastic::MigrationWorker`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/workers/elastic/migration_worker.rb) -will re-enqueue itself with a delay which is set using the `throttle_delay` option described below. The batching -must be handled within the `migrate` method, this setting controls the re-enqueuing only. - -- `batch_size` - Sets the number of documents modified during a `batched!` migration run. This size should be set to a value which allows the updates -enough time to finish. This can be tuned in combination with the `throttle_delay` option described below. The batching -must be handled within a custom `migrate` method or by using the [`Elastic::MigrationBackfillHelper`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/workers/concerns/elastic/migration_backfill_helper.rb) -`migrate` method which uses this setting. Default value is 1000 documents. - -- `throttle_delay` - Sets the wait time in between batch runs. This time should be set high enough to allow each migration batch -enough time to finish. Additionally, the time should be less than 30 minutes since that is how often the -[`Elastic::MigrationWorker`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/workers/elastic/migration_worker.rb) -cron worker runs. Default value is 5 minutes. - -- `pause_indexing!` - Pause indexing while the migration runs. This setting will record the indexing setting before -the migration runs and set it back to that value when the migration is completed. - -- `space_requirements!` - Verify that enough free space is available in the cluster when the migration runs. This setting - will halt the migration if the storage required is not available when the migration runs. The migration must provide - the space required in bytes by defining a `space_required_bytes` method. - -- `retry_on_failure` - Enable the retry on failure feature. By default, it retries - the migration 30 times. After it runs out of retries, the migration is marked as halted. - To customize the number of retries, pass the `max_attempts` argument: - `retry_on_failure max_attempts: 10` - -```ruby -# frozen_string_literal: true - -class BatchedMigrationName < Elastic::Migration - # Declares a migration should be run in batches - batched! - throttle_delay 10.minutes - pause_indexing! - space_requirements! - retry_on_failure - - # ... -end -``` - -### Multi-version compatibility - -These Advanced Search migrations, like any other GitLab changes, need to support the case where -[multiple versions of the application are running at the same time](multi_version_compatibility.md). - -Depending on the order of deployment, it's possible that the migration -has started or finished and there's still a server running the application code from before the -migration. We need to take this into consideration until we can -[ensure all Advanced Search migrations start after the deployment has finished](https://gitlab.com/gitlab-org/gitlab/-/issues/321619). - -### Reverting a migration - -Because Elasticsearch does not support transactions, we always need to design our -migrations to accommodate a situation where the application -code is reverted after the migration has started or after it is finished. - -For this reason we generally defer destructive actions (for example, deletions after -some data is moved) to a later merge request after the migrations have -completed successfully. To be safe, for self-managed customers we should also -defer it to another release if there is risk of important data loss. - -### Best practices for Advanced Search migrations - -Follow these best practices for best results: - -- When working in batches, keep the batch size under 9,000 documents - and `throttle_delay` for at least 3 minutes. The bulk indexer is set to run - every 1 minute and process a batch of 10,000 documents. These limits - allow the bulk indexer time to process records before another migration - batch is attempted. -- To ensure that document counts are up to date, it is recommended to refresh - the index before checking if a migration is completed. -- Add logging statements to each migration when the migration starts, when a - completion check occurs, and when the migration is completed. These logs - are helpful when debugging issues with migrations. -- Pause indexing if you're using any Elasticsearch Reindex API operations. -- Consider adding a retry limit if there is potential for the migration to fail. - This ensures that migrations can be halted if an issue occurs. - -## Deleting Advanced Search migrations in a major version upgrade - -Since our Advanced Search migrations usually require us to support multiple -code paths for a long period of time, it's important to clean those up when we -safely can. - -We choose to use GitLab major version upgrades as a safe time to remove -backwards compatibility for indices that have not been fully migrated. We -[document this in our upgrade documentation](../update/index.md#upgrading-to-a-new-major-version). -We also choose to replace the migration code with the halted migration -and remove tests so that: - -- We don't need to maintain any code that is called from our Advanced Search - migrations. -- We don't waste CI time running tests for migrations that we don't support - anymore. -- Operators who have not run this migration and who upgrade directly to the - target version will see a message prompting them to reindex from scratch. - -To be extra safe, we will not delete migrations that were created in the last -minor version before the major upgrade. So, if we are upgrading to `%14.0`, -we should not delete migrations that were only added in `%13.12`. This is an -extra safety net as we expect there are migrations that get merged that may -take multiple weeks to finish on GitLab.com. It would be bad if we upgraded -GitLab.com to `%14.0` before the migrations in `%13.12` were finished. Since -our deployments to GitLab.com are automated and we currently don't have -automated checks to prevent this, the extra precaution is warranted. -Additionally, even if we did have automated checks to prevent it, we wouldn't -actually want to hold up GitLab.com deployments on Advanced Search migrations, -as they may still have another week to go, and that's too long to block -deployments. - -### Process for removing migrations - -For every migration that was created 2 minor versions before the major version -being upgraded to, we do the following: - -1. Confirm the migration has actually completed successfully for GitLab.com. -1. Replace the content of the migration with: - - ```ruby - include Elastic::MigrationObsolete - ``` - -1. Delete any spec files to support this migration. -1. Remove any logic handling backwards compatibility for this migration. You - can find this by looking for - `Elastic::DataMigrationService.migration_has_finished?(:migration_name_in_lowercase)`. -1. Create a merge request with these changes. Noting that we should not - accidentally merge this before the major release is started. - ## Performance Monitoring ### Prometheus diff --git a/doc/development/ai_architecture.md b/doc/development/ai_architecture.md new file mode 100644 index 00000000000..e9994c8a6f4 --- /dev/null +++ b/doc/development/ai_architecture.md @@ -0,0 +1,108 @@ +--- +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 +--- + +# AI Architecture (Experiment) + +GitLab has created a common set of tools to support our product groups and their utilization of AI.

For more information about the circuit breaker pattern, see: + +- [What is Circuit breaker](https://martinfowler.com/bliki/CircuitBreaker.html). +- [The Hystrix documentation on CircuitBreaker](https://github.com/Netflix/Hystrix/wiki/How-it-Works#circuit-breaker). + +### Use CircuitBreaker + +To use the CircuitBreaker concern, you need to include it in a class. For example: + +```ruby +class MyService + include Gitlab::Llm::Concerns::CircuitBreaker + + def call_external_service + run_with_circuit do + # Code that interacts with external service goes here + + raise InternalServerError + end + end +end +``` + +The `call_external_service` method is an example method that interacts with an external service. +By wrapping the code that interacts with the external service with `run_with_circuit`, the method is executed within the circuit breaker. +The circuit breaker is created and configured by the `circuit` method, which is called automatically when the `CircuitBreaker` module is included. +The method should raise `InternalServerError` error which will be counted towards the error threshold if raised during the execution of the code block. + +The circuit breaker tracks the number of errors and the rate of requests, +and opens the circuit if it reaches the configured error threshold or volume threshold. +If the circuit is open, subsequent requests fail fast without executing the code block, and the circuit breaker periodically allows a small number of requests through to test the service's availability before closing the circuit again. + +### Configuration + +The circuit breaker is configured with two constants which control the number of errors and requests at which the circuit will open: + +- `ERROR_THRESHOLD` +- `VOLUME_THRESHOLD` + +You can adjust these values as needed for the specific service and usage pattern. +The `InternalServerError` is the exception class counted towards the error threshold if raised during the execution of the code block. +This is the exception class that triggers the circuit breaker when raised by the code that interacts with the external service. + +NOTE: +The `CircuitBreaker` module depends on the `Circuitbox` gem to provide the circuit breaker implementation. By default, the service name is inferred from the class name where the concern module is included. Override the `service_name` method if the name needs to be different. + +### Testing + +To test code that uses the `CircuitBreaker` concern, you can use `RSpec` shared examples and pass the `service` and `subject` variables: + +```ruby +it_behaves_like 'has circuit breaker' do + let(:service) { dummy_class.new } + let(:subject) { service.dummy_method } +end +``` + +## How to implement a new action + +### Register a new method + +Go to the `Llm::ExecuteMethodService` and add a new method with the new service class you will create. + +```ruby +class ExecuteMethodService < BaseService + METHODS = { + # ... + amazing_new_ai_feature: Llm::AmazingNewAiFeatureService + }.freeze +``` + +### Create a Service + +1. Create a new service under `ee/app/services/llm/` and inherit it from the `BaseService`. +1. The `resource` is the object we want to act on. It can be any object that includes the `Ai::Model` concern. For example it could be a `Project`, `MergeRequest`, or `Issue`. + +```ruby +# ee/app/services/llm/amazing_new_ai_feature_service.rb + +module Llm + class AmazingNewAiFeatureService < BaseService + private + + def perform + ::Llm::CompletionWorker.perform_async(user.id, resource.id, resource.class.name, :amazing_new_ai_feature) + success + end + + def valid? + super && Ability.allowed?(user, :amazing_new_ai_feature, resource) + end + end +end +``` + +### Authorization + +We recommend to use [policies](policies.md) to deal with authorization for a feature. Currently we need to make sure to cover the following checks: + +1. General AI feature flag is enabled +1. Feature specific feature flag is enabled +1. The namespace has the required license for the feature +1. User is a member of the group/project +1. Resource is allowed to be sent (see `send_to_ai?` method) +1. `experiment_features_enabled` and `third_party_ai_features_enabled` flags are set on the `Namespace` + +For our example, we need to implement the `allowed?(:amazing_new_ai_feature)` call. As an example, you can look at the [Issue Policy for the summarize comments feature](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/policies/ee/issue_policy.rb). In our example case, we want to implement the feature for Issues as well: + +```ruby +# ee/app/policies/ee/issue_policy.rb + +module EE + module IssuePolicy + extend ActiveSupport::Concern + prepended do + with_scope :subject + condition(:ai_available) do + ::Feature.enabled?(:openai_experimentation) && + @subject.send_to_ai? + end + + with_scope :subject + condition(:amazing_new_ai_feature_enabled) do + ::Feature.enabled?(:amazing_new_ai_feature, subject_container) && + subject_container.licensed_feature_available?(:amazing_new_ai_feature) + end + + rule do + ai_available & amazing_new_ai_feature_enabled & is_project_member + end.enable :amazing_new_ai_feature + end + end +end +``` + +### Implement `send_to_ai?` + +To make sure we only send data that is allowed to be sent, we have the `send_to_ai?` method. It checks if the resource is not confidential and public data. +Some resources already implement `send_to_ai?`. Make sure yours does as well. In our case, `Issue` is already covered with the `Issuable` concern. This is an example how it could look like: + +```ruby +# ee/app/models/concerns/ee + +def send_to_ai? + !try(:confidential) && resource_parent.public? +end +``` + +### Check if feature is allowed for this resource based on namespace settings + +There are two settings allowed on root namespace level that restrict the use of AI features: + +- `experiment_features_enabled` +- `third_party_ai_features_enabled`. + +To check if that feature is allowed for a given namespace, call: + +```ruby +Gitlab::Llm::StageCheck.available?(namespace, :name_of_the_feature) +``` + +Add the name of the feature to the `Gitlab::Llm::StageCheck` class. There are arrays there that differentiate +between experimental and beta features. + +This way we are ready for the following different cases: + +- If the feature is not in any array, the check will return `true`.

It includes sample projects you +can use to test functionality, and it gives you access to administrator functionality. +You can run it on your local machine, or use GitPod to run a remote version. + + + +If you've never used the GDK before, and you think you might contribute +more than once, you should install it. +If you already have a working GDK, you should +[update it to use the community fork](#an-existing-gdk-installation). + +### A new GDK installation + +Set aside about two hours to install the GDK.

Ensure you're on + [one of the supported platforms](https://gitlab.com/gitlab-org/gitlab-development-kit/-/tree/main/#supported-platforms) + (macOS, Ubuntu, etc.). +1. Choose the directory where you want to install the GDK. + In this location, a repository called `gitlab-development-kit` will be created, + and the application will be installed. +1. From the command line, go to that directory. + In this example, we will use the `development` directory. + + ```shell + cd development + ``` + +1. Run the one-line installation command: + + ```shell + curl "https://gitlab.com/gitlab-org/gitlab-development-kit/-/raw/main/support/install" | bash + ``` + +1. For the message `Where would you like to install the GDK? [./gitlab-development-kit]`, + press Enter to accept the default location. + +1. For the message `Which GitLab repo URL would you like to clone?`, enter the GitLab community fork: + + ```shell + https://gitlab.com/gitlab-community/gitlab.git + ``` + +While the installation is running, copy any messages that are displayed. +If you have any problems with the installation, you can use this output as +part of troubleshooting. + +When the installation is complete: + +1. Go to the directory where the GDK was installed: + + ```shell + cd gitlab-development-kit + ``` + +1. Start the GDK: + + ```shell + gdk start + ``` + +1. Connect to the GDK by using the URL provided. It should be something like <http://127.0.0.1:3000>. +1. Use the username `root` and the password `5iveL!fe`. You will be prompted + to reset your password the first time you sign in. + +If you have any problems, try going to the `gitlab-development-kit/gitlab` +directory and running these commands: + +```shell +yarn install && bundle install +bundle exec rails db:migrate RAILS_ENV=development +``` + +From the `gitlab-development-kit` folder, you can also try running `gdk doctor`. + +For more advanced troubleshooting, see +[the troubleshooting docs](https://gitlab.com/gitlab-org/gitlab-development-kit/-/tree/main/doc/troubleshooting). + +### An existing GDK installation + +If you have an existing GDK installation, you should update it so it's +using the community fork. + +1. Delete the existing `gitlab-development-kit/gitlab` directory. +1. Clone the community fork into that location: + + ```shell + cd gitlab-development-kit + git clone https://gitlab.com/gitlab-community/gitlab.git + ``` + +To confirm it was successful: + +1. Ensure the `gitlab-development-kit/gitlab` directory exists. +1. Go to the top `gitlab-development-kit` directory and run `gdk stop` and `gdk start`. + +If you get errors, run `gdk doctor` to troubleshoot. For more advanced troubleshooting, see +[the troubleshooting docs](https://gitlab.com/gitlab-org/gitlab-development-kit/-/tree/main/doc/troubleshooting). + +## Step 2: Change the code + +Now for the fun part. Let's edit some code. + +In this example, I found some UI text I'd like to change. +In the upper-right corner in GitLab, I selected my avatar and then **Preferences**. +I want to change this text: + + + +Other settings on the page start with the word `Customize` and skip the `This setting allows you to` part. +I'll update this phrase to match the others. + +1. Search the `gitlab-development-kit/gitlab` directory for the string `This setting allows you to customize`. + + The results show one `.haml` file, two `.md` files, one `.pot` file, and + several `.po` files. + +1. Open the `.haml` file. This file is where the UI text resides. +1. Update the string. In this case, I'll remove the words before `customize` + and start the word `customize` with a capital `C`. +1. Save the file. + +You can check that you were successful: + +- In the `gitlab-development-kit/gitlab` directory, type `git status` + to show the file you modified: + + ```shell + modified: app/views/profiles/preferences/show.html.haml + ``` + +- Refresh the web browser where you're viewing the GDK. + The changes should be displayed. Take a screenshot. + +  + +### Update the translation files + +English UI strings are localized into many languages. +These strings are saved in a `.pot` file, which you must update +any time you update UI text. + +To generate the localization file: + +1. Ensure you are in the `gitlab-development-kit/gitlab` directory. +1. Run the following command: + + ```shell + bin/rake gettext:compile + ``` + + After several minutes, a `.pot` file is generated in the `/locale` directory. + +Now, in the `gitlab-development-kit/gitlab` directory, if you type `git status` +you should have both files listed: + +```shell + modified: app/views/profiles/preferences/show.html.haml + modified: locale/gitlab.pot +``` + +For more information about localization, see [internationalization](../i18n/externalization.md). + +### Update the documentation + +Documentation for GitLab is published on <https://docs.gitlab.com>. +When you add or update a feature, you must update the docs as well. + +1. To find the documentation for a feature, the easiest thing is to search the + docs site. In this case, the setting is described on this documentation page: + + ```plaintext + https://docs.gitlab.com/ee/user/profile/preferences.html + ``` + +1. The URL shows you the location of the file in the `/doc` directory. + In this case, the location is: + + ```plaintext + doc/user/profile/preferences.md + ``` + +1. Go to this location in your local `gitlab` repository and update the `.md` file + and any related images. + +Now when you run `git status`, you should have something like: + +```plaintext + modified: app/views/profiles/preferences/show.html.haml + modified: doc/user/profile/img/profile-preferences-syntax-themes.png + modified: doc/user/profile/preferences.md + modified: locale/gitlab.pot +``` + +To view these changes in action, you can +[check out a merge request where these changes have already been made](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/116472). + +## Step 3: Push your changes to the community fork + +Now you're going to push your changes to the community fork. This is the next step +in getting your changes put into the main GitLab repository. + +1. Ensure you are in the `gitlab-development-kit/gitlab` directory. +1. Create a branch. You don't want to work in the `master` branch. + Instead, you want to create a branch for your work. In this example, + we're going to call the branch `ui-updates`. + + ```shell + git checkout -b ui-updates + ``` + +1. Add the files to the staging area. + + ```shell + git add . + ``` + +1. Provide a commit message. GitLab has somewhat strict + [commit message guidelines](merge_request_workflow.md#commit-messages-guidelines). + To be safe, a general rule is to use three to five words, start with a capital letter, + and do **not** end with a period. + + ```shell + git commit -m "Updating UI text + + Standardizing the text on this page so + that each area uses consistent language. + + Changelog: changed" + ``` + + The `Changelog: changed` is because we're changing an existing feature. If we were adding a feature, we'd + use `Changelog: added`. For details, see [changelog entries](../changelog.md). + +1. Push the changes to the community fork. At the same time, set the fork as your upstream, + so that it will be in sync for any future contributions. + + ```shell + git push --set-upstream origin ui-updates + ``` + +## Step 4: Create a merge request + +Now you're ready to push changes from the community fork to the main GitLab repository! + +1. Go to [the community fork on GitLab.com](https://gitlab.com/gitlab-community/gitlab). + You should see a message like this one: + +  + + Select **Create merge request**. + If you don't see this message, on the left sidebar, select **Merge requests > New merge request**. + +1. Take a look at the branch names. You should be merging from your branch + in the community fork to the `master` branch in the GitLab repository. + +  + +1. Fill out the information and then select **Save changes**. + Don't worry if your merge request is not complete. If you don't want anyone + from GitLab to review it, you can select the **Mark as draft** checkbox. + If you're not happy with the merge request after you create it, you can + close it, no harm done. + +1. Select the **Changes** tab. It should look something like this: + +  + + The red text shows the code before you made changes. The green shows what + the code looks like now. + +1. If you're happy with this merge request and want to start the review process, type + `@gitlab-bot ready` in a comment and then select **Comment**. + +  + +Someone from GitLab will look at your request and let you know what the next steps are. + +Now, any time you want to make a contribution to GitLab, you can just +go to the `gitlab-development-kit` folder and run `gdk update`.

A few corners we could cut: + +- The feature is available for GitLab Premium and GitLab Ultimate customers. + We don't have to sync all the data, but instead sync only the `merge_requests` records + which are part of licensed groups. +- Data changes (often) happen via the `MergeRequest` services, where bumping the + `updated_at` timestamp column is mostly consistent. Some sort of incremental + synchronization process could be implemented. +- We only need to query the merged merge requests. After the merge, the record rarely changes. + +### Database table structure + +The database table structure uses de-normalization to make all required columns +available in one database table.

Several columns of the merge request record may change, +so keeping the table up-to-date is important. + +The database table is ordered by the `project_id, merged_at, id` columns. This ordering +optimizes the table data for our use case: querying the `merged_at` column in a project. + +## Rewrite the count query + +First, let's generate some data for the table. + +```sql +INSERT INTO merge_requests (id, project_id, author_id, milestone_id, label_ids, merged_at, created_at) +SELECT id, project_id, author_id, milestone_id, label_ids, merged_at, created_at +FROM generateRandom('id UInt64, project_id UInt8, author_id UInt8, milestone_id UInt8, label_ids Array(UInt8), merged_at DateTime64(6, \'UTC\'), created_at DateTime64(6, \'UTC\')') +LIMIT 1000000; +``` + +NOTE: +Some integer data types were cast as `UInt8` so it is highly probable that they +have same values across different rows. + +The original count query only aggregated data for one month. With ClickHouse, we can +attempt aggregating the data for the whole year. + +PostgreSQL-based count query: + +```sql +SELECT COUNT(*) +FROM "merge_requests" +INNER JOIN "merge_request_metrics" ON "merge_request_metrics"."merge_request_id" = "merge_requests"."id" +WHERE (NOT EXISTS + (SELECT 1 + FROM "banned_users" + WHERE (merge_requests.author_id = banned_users.user_id))) + AND "merge_request_metrics"."target_project_id" = 278964 + AND "merge_request_metrics"."merged_at" >= '2022-12-01 00:00:00' + AND "merge_request_metrics"."merged_at" <= '2023-01-01 00:00:00' +``` + +ClickHouse query: + +```sql +SELECT + toYear(merged_at) AS year, + toMonth(merged_at) AS month, + COUNT(*) +FROM merge_requests +WHERE + project_id = 200 + AND merged_at BETWEEN '2022-01-01 00:00:00' + AND '2023-01-01 00:00:00' +GROUP BY year, month +``` + +The query processed a significantly lower number of rows compared to the generated data. +The `ORDER BY` clause (primary key) is helping the query execution: + +```plaintext +11 rows in set.

You can add more filters. +For example, filtering for a label and a milestone: + +```sql +SELECT + toYear(merged_at) AS year, + toMonth(merged_at) AS month, + COUNT(*) +FROM merge_requests +WHERE + project_id = 200 + AND milestone_id = 15 + AND has(label_ids, 118) + AND -- array includes 118 + merged_at BETWEEN '2022-01-01 00:00:00' + AND '2023-01-01 00:00:00' +GROUP BY year, month +``` + +Optimizing a particular filter is usually done with a database index. This particular +query reads 8000 rows: + +```plaintext +1 row in set. Elapsed: 0.016 sec. +Processed 8.19 thousand rows, 589.99 KB (505.38 thousand rows/s., 36.40 MB/s.) +``` + +Adding an index on `milestone_id`: + +```sql +ALTER TABLE merge_requests +ADD + INDEX milestone_id_index milestone_id TYPE minmax GRANULARITY 10; +ALTER TABLE + merge_requests MATERIALIZE INDEX milestone_id_index; +``` + +On the generated data, adding the index didn't improve the performance. + +### Banned users filter + +A recently added feature in GitLab filters out merge requests where the author is +banned by the admins. The banned users are tracked on the instance level in the +`banned_users` database table. + +#### Idea 1: Enumerate the banned user IDs + +This would require no structural changes to the ClickHouse database schema. +We could query the banned users in the project and filter the values out in query time. + +Get the banned users (in PostgreSQL): + +```sql +SELECT user_id FROM banned_users +``` + +In ClickHouse + +```sql +SELECT + toYear(merged_at) AS year, + toMonth(merged_at) AS month, + COUNT(*) +FROM merge_requests +WHERE + author_id NOT IN (1, 2, 3, 4) AND -- banned users + project_id = 200 + AND milestone_id = 15 + AND has(label_ids, 118) AND -- array includes 118 + merged_at BETWEEN '2022-01-01 00:00:00' + AND '2023-01-01 00:00:00' +GROUP BY year, month +``` + +The problem with this approach is that the number of banned users could increase significantly which would make the query bigger and slower. + +#### Idea 2: replicate the `banned_users` table + +Assuming that the `banned_users table` doesn't grow to millions of rows, we could +attempt to periodically sync the whole table to ClickHouse. With this approach, +a mostly consistent `banned_users` table could be used in the ClickHouse database query: + +```sql +SELECT + toYear(merged_at) AS year, + toMonth(merged_at) AS month, + COUNT(*) +FROM merge_requests +WHERE + author_id NOT IN (SELECT user_id FROM banned_users) AND + project_id = 200 AND + milestone_id = 15 AND + has(label_ids, 118) AND -- array includes 118 + merged_at BETWEEN '2022-01-01 00:00:00' AND '2023-01-01 00:00:00' +GROUP BY year, month +``` + +Alternatively, the `banned_users` table could be stored as a +[dictionary](https://clickhouse.com/docs/en/sql-reference/dictionaries/external-dictionaries/external-dicts) +to further improve the query performance. + +#### Idea 3: Alter the feature + +For analytical calculations, it might be acceptable to drop this particular filter. +This approach assumes that including the merge requests of banned users doesn't skew the statistics significantly. diff --git a/doc/development/database/clickhouse/tiered_storage.md b/doc/development/database/clickhouse/tiered_storage.md new file mode 100644 index 00000000000..d9026f47e28 --- /dev/null +++ b/doc/development/database/clickhouse/tiered_storage.md @@ -0,0 +1,138 @@ +--- +stage: Data Stores +group: Database +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 +--- + +# Tiered Storages in ClickHouse + +NOTE: +The MergeTree table engine in ClickHouse supports tiered storage. +See the documentation for [Using Multiple Block Devices for Data Storage](https://clickhouse.com/docs/en/engines/table-engines/mergetree-family/mergetree#table_engine-mergetree-multiple-volumes) +for details on setup and further explanation. + +Quoting from the [MergeTree documentation](https://clickhouse.com/docs/en/engines/table-engines/mergetree-family/mergetree#table_engine-mergetree-multiple-volumes): + +<!-- vale gitlab.Simplicity = NO --> + +> MergeTree family table engines can store data on multiple block devices.

If you are only interested in some of the props, you can use [`toMatchObject`](https://jestjs.io/docs/expect#tomatchobjectobject).

If these issues are not done in the current release, they will + strongly be considered for the next release. +- `~"Next Patch Release"`: Issues to put in the next patch release. Work on these + first, and follow the [patch release runbook](https://gitlab.com/gitlab-org/release/docs/-/blob/master/general/patch/engineers.md) to backport the bug fix to the current version. + +Each issue scheduled for the current milestone should be labeled `~"Deliverable"~` +or `~"Stretch"`. Any open issue for a previous milestone should be labeled +`~"Next Patch Release"`, or otherwise rescheduled to a different milestone. + +## Priority labels + +We have the following priority labels: + +- `~"priority::1"` +- `~"priority::2"` +- `~"priority::3"` +- `~"priority::4"` + +Please refer to the issue triage [priority label](https://about.gitlab.com/handbook/engineering/quality/issue-triage/#priority) section in our handbook to see how it's used. + +## Severity labels + +We have the following severity labels: + +- `~"severity::1"` +- `~"severity::2"` +- `~"severity::3"` +- `~"severity::4"` + +Please refer to the issue triage [severity label](https://about.gitlab.com/handbook/engineering/quality/issue-triage/#severity) section in our handbook to see how it's used. + +## Label for community contributors + +There are many issues that have a clear solution with uncontroversial benefit to GitLab users. +However, GitLab might not have the capacity for all these proposals in the current roadmap. +These issues are labeled `~"Seeking community contributions"` because we welcome merge requests to resolve them. + +Community contributors can submit merge requests for any issue they want, but +the `~"Seeking community contributions"` label has a special meaning. It points to +changes that: + +1. We already agreed on, +1. Are well-defined, +1. Are likely to get accepted by a maintainer. + +We want to avoid a situation when a contributor picks an +~"Seeking community contributions" issue and then their merge request gets closed, +because we realize that it does not fit our vision, or we want to solve it in a +different way. + +We manually add the `~"Seeking community contributions"` label to issues +that fit the criteria described above. +We do not automatically add this label, because it requires human evaluation. + +We recommend people that have never contributed to any open source project to +look for issues labeled `~"Seeking community contributions"` with a +[weight of 1](https://gitlab.com/groups/gitlab-org/-/issues?sort=created_date&state=opened&label_name[]=Seeking+community+contributions&assignee_id=None&weight=1) or the `~"quick win"` +[label](https://gitlab.com/gitlab-org/gitlab/-/issues?scope=all&state=opened&label_name[]=quick%20win&assignee_id=None) +attached to it. +More experienced contributors are very welcome to tackle +[any of them](https://gitlab.com/groups/gitlab-org/-/issues?sort=created_date&state=opened&label_name[]=Seeking+community+contributions&assignee_id=None). + +For more complex features that have a weight of 2 or more and clear scope, we recommend looking at issues +with the [label `~"Community Challenge"`](https://gitlab.com/gitlab-org/gitlab/-/issues?sort=created_date&state=opened&label_name[]=Seeking+community+contributions&label_name[]=Community+challenge). +If your MR for the `~"Community Challenge"` issue gets merged, you will also have a chance to win a custom +GitLab merchandise. + +If you've decided that you would like to work on an issue, please @-mention +the [appropriate product manager](https://about.gitlab.com/handbook/product/#who-to-talk-to-for-what) +as soon as possible. The product manager will then pull in appropriate GitLab team +members to further discuss scope, design, and technical considerations. This will +ensure that your contribution is aligned with the GitLab product and minimize +any rework and delay in getting it merged into main. + +GitLab team members who apply the `~"Seeking community contributions"` label to an issue +should update the issue description with a responsible product manager, inviting +any potential community contributor to @-mention per above. + +## Stewardship label + +For issues related to the open source stewardship of GitLab, +there is the `~"stewardship"` label. + +This label is to be used for issues in which the stewardship of GitLab +is a topic of discussion. For instance if GitLab Inc. is planning to add +features from GitLab EE to GitLab CE, related issues would be labeled with +`~"stewardship"`. + +A recent example of this was the issue for +[bringing the time tracking API to GitLab CE](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/25517#note_20019084). + +## Technical and UX debt + +In order to track things that can be improved in the GitLab codebase, +we use the `~"technical debt"` label in the [GitLab issue tracker](https://gitlab.com/gitlab-org/gitlab/-/issues). +We use the `~"UX debt"` label when we choose to deviate from the MVC, in a way that harms the user experience. + +These labels should be added to issues that describe things that can be improved, +shortcuts that have been taken, features that need additional attention, and all +other things that have been left behind due to high velocity of development. +For example, code that needs refactoring should use the `~"technical debt"` label, +something that didn't ship according to our Design System guidelines should +use the `~"UX debt"` label. + +Everyone can create an issue, though you may need to ask for adding a specific +label, if you do not have permissions to do it by yourself. Additional labels +can be combined with these labels, to make it easier to schedule +the improvements for a release. + +Issues tagged with these labels have the same priority like issues +that describe a new feature to be introduced in GitLab, and should be scheduled +for a release by the appropriate person. + +Make sure to mention the merge request that the `~"technical debt"` issue or +`~"UX debt"` issue is associated with in the description of the issue. diff --git a/doc/development/lfs.md b/doc/development/lfs.md index ec91f9f3c8b..bb327bf5d04 100644 --- a/doc/development/lfs.md +++ b/doc/development/lfs.md @@ -3,15 +3,147 @@ stage: Create group: Source Code 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 --- - -# Git LFS developer information +# Git LFS development guidelines This page contains developer-centric information for GitLab team members.

When successful, the same TCP connection can then be used by both client +and server to send and receive data in either direction. + +Because the WebSocket protocol does not prescribe how the transmitted data is encoded or structured, +we need libraries like Action Cable that take care of these concerns. Action Cable: + +- Handles the initial connection upgrade from HTTP to the WebSocket protocol. Subsequent requests using + the `ws://` scheme are then handled by the Action Cable server and not Action Pack. +- Defines how data transmitted over the WebSocket is encoded. Action Cable specifies this to be JSON. This allows the + application to provide data as a Ruby Hash and Action Cable (de)serializes it from and to JSON. +- Provides callback hooks to handle clients connecting or disconnecting and client authentication. +- Provides `ActionCable::Channel` as a developer abstraction to implement publish/subscribe and remote procedure calls. + +Action Cable supports different implementations to track which client is subscribed to which +`ActionCable::Channel`. At GitLab we use the Redis adapter, which uses +[Redis PubSub](https://redis.io/docs/manual/pubsub/) channels as a distributed message bus. +Shared storage is necessary because different clients might connect to the same Action Cable channel +from different Puma instances. + +NOTE: +Do not confuse Action Cable channels with Redis PubSub channels. An Action Cable `Channel` object is a +programming abstraction to classify and handle the various kinds of data going over the WebSocket connection. +In Action Cable, the underlying PubSub channel is referred to as a broadcasting instead and the association +between a client and a broadcasting is called a subscription. In particular, there can be many broadcastings +(PubSub channels) and subscriptions for each Action Cable `Channel`. + +Because Action Cable allows us to express different kinds of behavior through its `Channel` API, and because +updates to any `Channel` can use the same WebSocket connection, we only require a single WebSocket connection +to be established for each GitLab page to enhance a view component on that page with real-time behavior. + +To implement real-time updates on a GitLab page, we do not write individual `Channel` implementations. +Instead, we provide the `GraphqlChannel` to which all pages that require push-based updates on GitLab +subscribe. + +### GraphQL subscriptions: Backend + +GitLab supports [GraphQL](https://graphql.org) for clients to request structured data from the server +using GraphQL queries. Refer to the [GitLab GraphQL overview](../api/graphql/index.md) to learn about why we adopted GraphQL. +GraphQL support in the GitLab backend is provided by the [`graphql-ruby`](https://graphql-ruby.org) gem. + +Ordinarily, GraphQL queries are client-initiated HTTP POST requests that follow the standard request-response cycle. +For real-time functionality, we use GraphQL subscriptions instead, which are an implementation of the publish/subscribe pattern. +In this approach the client first sends a subscription request to the `GraphqlChannel` with the: + +- Name of the subscription `field` (the event name). +- GraphQL query to run when this event triggers. + +This information is used by the server to create a `topic` that represents this event stream. The topic is a unique name +derived from the subscription arguments and event name and is used to identify all subscribers +that need to be informed if the event triggers. More than one client can subscribe to the +same topic. For example, `issuableAssigneesUpdated:issuableId:<hashed_id>` might serve as the topic +that clients subscribe to if they wish to be updated whenever the assignees for the issue with the +given ID change. + +The backend is responsible for triggering a subscription, typically in response to a domain +event such as "issue added to epic" or "user assigned to issue". At GitLab, this could be a service object +or an ActiveRecord model object. +A trigger is executed by calling into [`GitlabSchema.subscriptions.trigger`](https://gitlab.com/gitlab-org/gitlab/-/blob/5e3c334116178eec5f50fc5fee2ec0b3841a2504/app/graphql/graphql_triggers.rb) with the respective event name and arguments, +from which `graphql-ruby` derives the topic. It then finds all subscribers for this topic, executes the query for +each subscriber, and pushes the result back to all topic subscribers. + +Because we use Action Cable as the underlying transport for GraphQL subscriptions, topics are implemented +as Action Cable broadcastings, which as mentioned above represent Redis PubSub channels. +This means that for each subscriber, two PubSub channels are used: + +- One `graphql-event:<namespace>:<topic>` channel per each topic. This channel is used to track which client is subscribed + to which event and is shared among all potential clients. The use of a `namespace` is optional and it can be blank. +- One `graphql-subscription:<subscription-id>` channel per each client. This channel is used to transmit the query result + back to the respective client and hence cannot be shared between different clients. + +The next section describes how the GitLab frontend uses GraphQL subscriptions to implement real-time updates. + +### GraphQL subscriptions: Frontend + +Because the GitLab frontend executes JavaScript, not Ruby, we need a different GraphQL implementation +to send GraphQL queries, mutations, and subscriptions from the client to the server. +We use [Apollo](https://www.apollographql.com) to do this. + +Apollo is a comprehensive implementation of GraphQL in JavaScript and is split into `apollo-server` and `apollo-client` +as well as additional utility modules. Because we run a Ruby backend, we use `apollo-client` instead of `apollo-server`. + +It simplifies: + +- Networking, connection management and request routing. +- Client-side state management and response caching. +- Integrating GraphQL with view components using a bridge module. + +NOTE: +When reading the Apollo Client documentation, it assumes that React.js is used for view rendering. We do not use React.js +at GitLab. We use Vue.js, which integrates with Apollo using the [Vue.js adapter](https://apollo.vuejs.org/). + +Apollo provides functions and hooks with which you define how: + +- Views send queries, mutations or subscriptions. +- Responses should be dealt with. +- Response data is cached. + +The entry point is `ApolloClient`, which is a GraphQL client object that: + +- Is shared between all view components on a single page. +- All view components use internally to communicate with the server. + +To decide how different types of requests should be routed, Apollo uses the `ApolloLink` abstraction. Specifically, +it splits real-time server subscriptions from other GraphQL requests using the `ActionCableLink`. This: + +- Establishes the WebSocket connection to Action Cable. +- Maps server pushes to an `Observable` event stream in the client that views can subscribe to in order to update themselves. + +For more information about Apollo and Vue.js, see the [GitLab GraphQL development guide](fe_guide/graphql.md). diff --git a/doc/development/redis.md b/doc/development/redis.md index 68cab9ac38d..5073d9350e8 100644 --- a/doc/development/redis.md +++ b/doc/development/redis.md @@ -4,7 +4,7 @@ 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 --- -# Redis guidelines +# Redis development guidelines ## Redis instances @@ -56,7 +56,7 @@ the entry, instead of relying on the key changing. ### Multi-key commands -We don't use Redis Cluster, but support for it is tracked in [this issue](https://gitlab.com/gitlab-org/gitlab/-/issues/118820). +GitLab supports Redis Cluster only for the Redis [rate-limiting](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/redis/rate_limiting.rb) type, introduced in [epic 823](https://gitlab.com/groups/gitlab-com/gl-infra/-/epics/823).

If set, [`Elastic::MigrationWorker`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/workers/elastic/migration_worker.rb) + re-enqueues itself with a delay which is set using the `throttle_delay` option described below. The batching + must be handled in the `migrate` method. This setting controls the re-enqueuing only. + +- `batch_size` - Sets the number of documents modified during a `batched!` migration run. This size should be set to a value which allows the updates + enough time to finish. This can be tuned in combination with the `throttle_delay` option described below. The batching + must be handled in a custom `migrate` method or by using the [`Elastic::MigrationBackfillHelper`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/workers/concerns/elastic/migration_backfill_helper.rb) + `migrate` method which uses this setting. Default value is 1000 documents. + +- `throttle_delay` - Sets the wait time in between batch runs. This time should be set high enough to allow each migration batch + enough time to finish. Additionally, the time should be less than 5 minutes because that is how often the + [`Elastic::MigrationWorker`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/workers/elastic/migration_worker.rb) + cron worker runs. The default value is 3 minutes. + +- `pause_indexing!` - Pause indexing while the migration runs.

This setting + halts the migration if the storage required is not available when the migration runs. The migration must provide + the space required in bytes by defining a `space_required_bytes` method. + +- `retry_on_failure` - Enable the retry on failure feature. By default, it retries + the migration 30 times. After it runs out of retries, the migration is marked as halted. + To customize the number of retries, pass the `max_attempts` argument: + `retry_on_failure max_attempts: 10` + +```ruby +# frozen_string_literal: true + +class BatchedMigrationName < Elastic::Migration + # Declares a migration should be run in batches + batched! + throttle_delay 10.minutes + pause_indexing! + space_requirements! + retry_on_failure + + # ... +end +``` + +### Multi-version compatibility + +These advanced search migrations, like any other GitLab changes, need to support the case where +[multiple versions of the application are running at the same time](../multi_version_compatibility.md). + +Depending on the order of deployment, it's possible that the migration +has started or finished and there's still a server running the application code from before the +migration. We need to take this into consideration until we can +[ensure all advanced search migrations start after the deployment has finished](https://gitlab.com/gitlab-org/gitlab/-/issues/321619). + +### Reverting a migration + +Because Elasticsearch does not support transactions, we always need to design our +migrations to accommodate a situation where the application +code is reverted after the migration has started or after it is finished. + +For this reason we generally defer destructive actions (for example, deletions after +some data is moved) to a later merge request after the migrations have +completed successfully. To be safe, for self-managed customers we should also +defer it to another release if there is risk of important data loss. + +### Best practices for advanced search migrations + +Follow these best practices for best results: + +- Order all migrations for each document type so that any migrations that use + [`Elastic::MigrationUpdateMappingsHelper`](#elasticmigrationupdatemappingshelper) + are executed before migrations that use the + [`Elastic::MigrationBackfillHelper`](#elasticmigrationbackfillhelper). This avoids + reindexing the same documents multiple times if all of the migrations are unapplied + and reduces the backfill time. +- When working in batches, keep the batch size under 9,000 documents. + The bulk indexer is set to run every minute and process a batch + of 10,000 documents. This way, the bulk indexer has time to + process records before another migration batch is attempted. +- To ensure that document counts are up to date, you should refresh + the index before checking if a migration is completed. +- Add logging statements to each migration when the migration starts, when a + completion check occurs, and when the migration is completed. These logs + are helpful when debugging issues with migrations. +- Pause indexing if you're using any Elasticsearch Reindex API operations. +- Consider adding a retry limit if there is potential for the migration to fail. + This ensures that migrations can be halted if an issue occurs. + +## Deleting advanced search migrations in a major version upgrade + +Because our advanced search migrations usually require us to support multiple +code paths for a long period of time, it's important to clean those up when we +safely can. + +We choose to use GitLab major version upgrades as a safe time to remove +backwards compatibility for indices that have not been fully migrated. We +[document this in our upgrade documentation](../../update/index.md#upgrading-to-a-new-major-version). +We also choose to replace the migration code with the halted migration +and remove tests so that: + +- We don't need to maintain any code that is called from our advanced search + migrations. +- We don't waste CI time running tests for migrations that we don't support + anymore. +- Operators who have not run this migration and who upgrade directly to the + target version see a message prompting them to reindex from scratch. + +To be extra safe, we do not delete migrations that were created in the last +minor version before the major upgrade. So, if we are upgrading to `%14.0`, +we should not delete migrations that were only added in `%13.12`. This +extra safety net allows for migrations that might +take multiple weeks to finish on GitLab.com. It would be bad if we upgraded +GitLab.com to `%14.0` before the migrations in `%13.12` were finished. Because +our deployments to GitLab.com are automated and we don't have +automated checks to prevent this, the extra precaution is warranted. +Additionally, even if we did have automated checks to prevent it, we wouldn't +actually want to hold up GitLab.com deployments on advanced search migrations, +as they may still have another week to go, and that's too long to block +deployments. + +### Process for removing migrations + +For every migration that was created 2 minor versions before the major version +being upgraded to, we do the following: + +1. Confirm the migration has actually completed successfully for GitLab.com. +1. Replace the content of the migration with: + + ```ruby + include Elastic::MigrationObsolete + ``` + +1. Delete any spec files to support this migration. +1. Remove any logic handling backwards compatibility for this migration.

This provides better readability and more resilient testing. If you look at the examples below, notice how the assertions on the snapshots do not tell you what you are expecting to see.

However, there are some cases where it might be tempting to use snapshots when the value returned has a lot of inconsistent spacing due to formatting or HTML nesting. + +In these instances, it is better to assert each string individually and make multiple assertions than to use a snapshot to ignore the spaces. This is because any change to the DOM layout will fail the snapshot test even if the text is still perfectly formatted. + +```vue +<template> + <gl-sprintf :message="my-message"> + <template #code="{ content }"> + <code>{{ content }}</code> + </template> + </gl-sprintf> + <p> My second message </p> +</template> +``` + +Bad: + +```javascript +it('renders the text as I expect', () => { + expect(wrapper.text()).toMatchSnapshot() +}) +``` + +Good: + +```javascript +it('renders the code snippet', () => { + expect(findCodeTag().text()).toContain("myFunction()") +}) + +it('renders the paragraph text', () => { + expect(findOtherText().text()).toBe("My second message") +}) +``` + +#### Example #3 - Complex HTML + +When we have very complex HTML, we should focus on asserting specific sensitive and meaningful points rather than capturing it as a whole. The value in a snapshot test is to **warn developers** that they might have accidentally change an HTML structure that they did not intend to change. If the output of the change is hard to read, which is often the case with complex HTML output, then **is the signal itself that something changed** sufficient? And if it is, can it be accomplished without snapshots? + +A good example of a complex HTML output is `GlTable`. Snapshot testing might feel like a good option since you can capture rows and columns structure, but we should instead try to assert text we expect or count the number of rows and columns manually. + +```vue +<template> + <gl-table ...all-them-props /> +</template> +``` + +Bad: + +```javascript +it('renders GlTable as I expect', () => { + expect(findGlTable().element).toMatchSnapshot() +}) +``` + +Good: + +```javascript +it('renders the right number of rows', () => { + expect(findGlTable().findAllRows()).toHaveLength(expectedLength) +}) + +it('renders the special icon that only appears on a full moon', () => { + expect(findGlTable().findMoonIcon().exists()).toBe(true) +}) + +it('renders the correct email format', () => { + expect(findGlTable().text()).toContain('my_strange_email@shaddyprovide.com') +}) +``` + +Although more verbose, this now means that our tests are not going to break if `GlTable` changes its internal implementation, we communicate to other developers (or ourselves in 6 months) what is important to preserve when refactoring or adding to our table. + ### How to take a snapshot ```javascript @@ -1211,43 +1434,6 @@ it('renders the component correctly', () => { The above test will create two snapshots.

Some features, such as epics, are -only available at the group level. Some features, such as issues, are only available -at the project level. Other features, such as milestones, are available to both groups -and projects. - -We receive many requests to add features either to the group or project level. -Moving features around to different levels is problematic on multiple levels: - -- It requires engineering time to move the features. -- It requires UX overhead to maintain mental models of feature availability. -- It creates redundant code. - -When features are copied from one level (project, group, or instance) to another, -the copies often have small, nuanced differences between them. These nuances cause -extra engineering time when fixes are needed, because the fix must be copied to -several locations. These nuances also create different user experiences when the -feature is used in different places. - -A solution for this problem is to consolidate groups and projects into a single -entity, `namespace`. The work on this solution is split into several phases and -is tracked in [epic 6473](https://gitlab.com/groups/gitlab-org/-/epics/6473). - -### Phase 1 - -- [Phase 1 epic](https://gitlab.com/groups/gitlab-org/-/epics/6697). -- **Goals**: - 1. Ensure every project receives a corresponding record in the `namespaces` - table with `type='Project'`. - 1. For user namespaces, the type changes from `NULL` to `User`. - -We should make sure that projects, and the project namespace, are equivalent: - -- **Create project:** use Rails callbacks to ensure a new project namespace is - created for each project. Project namespace records should contain `created_at` and - `updated_at` attributes equal to the project's `created_at`/`updated_at` attributes. -- **Update project:** use the `after_save` callback in Rails to ensure some - attributes are kept in sync between project and project namespaces. - Read [`project#after_save`](https://gitlab.com/gitlab-org/gitlab/blob/6d26634e864d7b748dda0e283eb2477362263bc3/app/models/project.rb#L101-L101) - for more information. -- **Delete project:** use FKs cascade delete or Rails callbacks to ensure when a `Project` - or its `ProjectNamespace` is removed, its corresponding `ProjectNamespace` or `Project` - is also removed. -- **Transfer project to a different group:** make sure that when a project is transferred, - its corresponding project namespace is transferred to the same group. -- **Transfer group:** make sure when transferring a group that all of its sub-projects, - either direct or through descendant groups, have their corresponding project - namespaces transferred correctly as well. -- **Export or import project** - - **Export project** continues to export only the project, and not its project namespace, - in this phase. The project namespace does not contain any specific information - to export at this point. Eventually we want the project namespace to be exported as well. - - **Import project** creates a new project, so the project namespace is created through - Rails `after_save` callback on the project model. -- **Export or import group:** when importing or exporting a `Group`, projects are not - included in the operation. If that feature is changed to include `Project` when its group is - imported or exported, the logic must include their corresponding project namespaces - in the import or export. - -After ensuring these points, run a database migration to create a `ProjectNamespace` -record for every `Project`. Project namespace records created during the migration -should have `created_at` and `updated_at` attributes set to the migration runtime. -The project namespaces' `created_at` and `updated_at` attributes would not match -their corresponding project's `created_at` and `updated_at` attributes. We want -the different dates to help audit any of the created project namespaces, in case we need it. -After this work completes, we must migrate data as described in -[Backfill `ProjectNamespace` for every Project](https://gitlab.com/gitlab-org/gitlab/-/issues/337100). - -### Phase 2 - -- [Phase 2 epic](https://gitlab.com/groups/gitlab-org/-/epics/6768). -- **Goal**: Link `ProjectNamespace` to other entities on the database level. - -In this phase: - -- Communicate the changes company-wide at the engineering level. We want to make - engineers aware of the upcoming changes, even though teams are not expected to - collaborate actively until phase 3. -- Raise awareness to avoid regressions, and conflicting or duplicate work that - can be dealt with before phase 3. - -### Phase 3 - -- [Phase 3 epic](https://gitlab.com/groups/gitlab-org/-/epics/6585). -- **Goal**: Achieve feature parity between the namespace types. -Problems to solve as part of this phase: - -- Routes handling through `ProjectNamespace` rather than `Project`. -- Memberships handling. -- Policies handling. -- Import and export. -- Other interactions between project namespace and project models. - -Phase 3 is when the active migration of features from `Project` to `ProjectNamespace`, -or directly to `Namespace`, happens. - -### How to plan features that interact with Group and ProjectNamespace - -As of now, every Project in the system has a record in the `namespaces` table. This makes it possible to -use common interface to create features that are shared between Groups and Projects. Shared behavior can be added using -a concerns mechanism. Because the `Namespace` model is responsible for `UserNamespace` methods as well, it is discouraged -to use the `Namespace` model for shared behavior for Projects and Groups. - -#### Resource-based features - -To migrate resource-based features, existing functionality will need to be supported. This can be achieved in two Phases. - -**Phase 1 - Setup** - -- Link into the namespaces table - - Add a column to the table - - For example, in issues a `project id` points to the projects table. We need to establish a link to the `namespaces` table. - - Modify code so that any new record already has the correct data in it - - Backfill - -**Phase 2 - Prerequisite work** - -- Investigate the permission model as well as any performance concerns related to that. - - Permissions need to be checked and kept in place. -- Investigate what other models need to support namespaces for functionality dependent on features you migrate in Phase 1. -- Adjust CRUD services and APIs (REST and GraphQL) to point to the new column you added in Phase 1. -- Consider performance when fetching resources. - -Introducing new functionality is very much dependent on every single team and feature. - -#### Settings-related features - -Right now, cascading settings are available for `NamespaceSettings`. By creating `ProjectNamespace`, -we can use this framework to make sure that some settings are applicable on the project level as well. - -When working on settings, we need to make sure that: - -- They are not used in `join` queries or modify those queries. -- Updating settings is taken into consideration. -- If we want to move from project to project namespace, we follow a similar database process to the one described in [Phase 1](#phase-1). - -## Related topics - -- [Consolidating groups and projects](../../architecture/blueprints/consolidating_groups_and_projects/index.md) - architecture documentation -- [Organization user documentation](../../user/workspace/index.md) +<!-- This redirect file can be deleted after <2023-06-13>. --> +<!-- Redirects that point to other docs in the same project expire in three months. --> +<!-- Redirects that point to docs in a different project or site (link is not relative and starts with `https:`) expire in one year. --> +<!-- Before deletion, see: https://docs.gitlab.com/ee/development/documentation/redirects.html --> |
