This new +importer performs its work in parallel using Sidekiq, greatly reducing the time +necessary to import GitHub projects into a GitLab instance. + +The GitHub importer offers two different types of importers: a sequential +importer and a parallel importer. The Rake task `import:github` uses the +sequential importer, while everything else uses the parallel importer. The +difference between these two importers is quite simple: the sequential importer +does all work in a single thread, making it more useful for debugging purposes +or Rake tasks. The parallel importer on the other hand uses Sidekiq. + +## Requirements + +* GitLab CE 10.2.0 or newer. +* Sidekiq workers that process the `github_importer` and + `github_importer_advance_stage` queues (this is enabled by default). +* Octokit (used for interacting with the GitHub API) + +## Code structure + +The importer's codebase is broken up into the following directories: + +* `lib/gitlab/github_import`: this directory contains most of the code such as + the classes used for importing resources. +* `app/workers/gitlab/github_import`: this directory contains the Sidekiq + workers. +* `app/workers/concerns/gitlab/github_import`: this directory contains a few + modules reused by the various Sidekiq workers. + +## Architecture overview + +When a GitHub project is imported we schedule and execute a job for the +`RepositoryImportworker` worker as all other importers. However, unlike other +importers we don't immediately perform the work necessary. Instead work is +divided into separate stages, with each stage consisting out of a set of Sidekiq +jobs that are executed. Between every stage a job is scheduled that periodically +checks if all work of the current stage is completed, advancing the import +process to the next stage when this is the case. The worker handling this is +called `Gitlab::GithubImport::AdvanceStageWorker`. + +## Stages + +### 1. RepositoryImportWorker + +This worker will kick off the import process by simply scheduling a job for the +next worker. + +### 2. Stage::ImportRepositoryWorker + +This worker will import the repository and wiki, scheduling the next stage when +done. + +### 3. Stage::ImportBaseDataWorker + +This worker will import base data such as labels, milestones, and releases. This +work is done in a single thread since it can be performed fast enough that we +don't need to perform this work in parallel. + +### 4. Stage::ImportPullRequestsWorker + +This worker will import all pull requests. For every pull request a job for the +`Gitlab::GithubImport::ImportPullRequestWorker` worker is scheduled. + +### 5. Stage::ImportIssuesAndDiffNotesWorker + +This worker will import all issues and pull request comments. For every issue we +schedule a job for the `Gitlab::GithubImport::ImportIssueWorker` worker. For +pull request comments we instead schedule jobs for the +`Gitlab::GithubImport::DiffNoteImporter` worker. + +This worker processes both issues and diff notes in parallel so we don't need to +schedule a separate stage and wait for the previous one to complete. + +Issues are imported separately from pull requests because only the "issues" API +includes labels for both issue and pull requests. Importing issues and setting +label links in the same worker removes the need for performing a separate crawl +through the API data, reducing the number of API calls necessary to import a +project. + +### 6. Stage::ImportNotesWorker + +This worker imports regular comments for both issues and pull requests. For +every comment we schedule a job for the +`Gitlab::GithubImport::ImportNoteWorker` worker. + +Regular comments have to be imported at the end since the GitHub API used +returns comments for both issues and pull requests. This means we have to wait +for all issues and pull requests to be imported before we can import regular +comments. + +### 7. Stage::FinishImportWorker + +This worker will wrap up the import process by performing some housekeeping +(such as flushing any caches) and by marking the import as completed. + +## Advancing stages + +Advancing stages is done in one of two ways: + +1. Scheduling the worker for the next stage directly. +2. Scheduling a job for `Gitlab::GithubImport::AdvanceStageWorker` which will + advance the stage when all work of the current stage has been completed. + +The first approach should only be used by workers that perform all their work in +a single thread, while `AdvanceStageWorker` should be used for everything else. + +The way `AdvanceStageWorker` works is fairly simple. When scheduling a job it +will be given a project ID, a list of Redis keys, and the name of the next +stage. The Redis keys (produced by `Gitlab::JobWaiter`) are used to check if the +currently running stage has been completed or not. If the stage has not yet been +completed `AdvanceStageWorker` will reschedule itself. Once a stage finishes +`AdvanceStageworker` will refresh the import JID (more on this below) and +schedule the worker of the next stage. + +To reduce the number of `AdvanceStageWorker` jobs scheduled this worker will +briefly wait for jobs to complete before deciding what the next action should +be. For small projects this may slow down the import process a bit, but it will +also reduce pressure on the system as a whole. + +## Refreshing import JIDs + +GitLab includes a worker called `StuckImportJobsWorker` that will periodically +run and mark project imports as failed if they have been running for more than +15 hours. For GitHub projects this poses a bit of a problem: importing large +projects could take several hours depending on how often we hit the GitHub rate +limit (more on this below), but we don't want `StuckImportJobsWorker` to mark +our import as failed because of this. + +To prevent this from happening we periodically refresh the expiration time of +the import process. This works by storing the JID of the import job in the +database, then refreshing this JID's TTL at various stages throughout the import +process. This is done by calling `Project#refresh_import_jid_expiration`. By +refreshing this TTL we can ensure our import does not get marked as failed so +long we're still performing work. + +## GitHub rate limit + +GitHub has a rate limit of 5 000 API calls per hour. The number of requests +necessary to import a project is largely dominated by the number of unique users +involved in a project (e.g. issue authors). Other data such as issue pages +and comments typically only requires a few dozen requests to import. This is +because we need the Email address of users in order to map them to GitLab users. + +We handle this by doing the following: + +1. Once we hit the rate limit all jobs will automatically reschedule themselves + in such a way that they are not executed until the rate limit has been reset. +2. We cache the mapping of GitHub users to GitLab users in Redis. + +More information on user caching can be found below. + +## Caching user lookups + +When mapping GitHub users to GitLab users we need to (in the worst case) +perform: + +1. One API call to get the user's Email address. +2. Two database queries to see if a corresponding GitLab user exists. One query + will try to find the user based on the GitHub user ID, while the second query + is used to find the user using their GitHub Email address. + +Because this process is quite expensive we cache the result of these lookups in +Redis. For every user looked up we store three keys: + +1. A Redis key mapping GitHub usernames to their Email addresses. +2. A Redis key mapping a GitHub Email addresses to a GitLab user ID. +3. A Redis key mapping a GitHub user ID to GitLab user ID. + +There are two types of lookups we cache: + +1. A positive lookup, meaning we found a GitLab user ID. +2. A negative lookup, meaning we didn't find a GitLab user ID. Caching this + prevents us from performing the same work for users that we know don't exist + in our GitLab database. + +The expiration time of these keys is 24 hours. When retrieving the cache of a +positive lookups we refresh the TTL automatically. The TTL of false lookups is +never refreshed. + +Because of this caching layer it's possible newly registered GitLab accounts +won't be linked to their corresponding GitHub accounts. This however will sort +itself out once the cached keys expire. + +The user cache lookup is shared across projects. This means that the more +projects get imported the fewer GitHub API calls will be needed. + +The code for this resides in: + +* `lib/gitlab/github_import/user_finder.rb` +* `lib/gitlab/github_import/caching.rb` + +## Mapping labels and milestones + +To reduce pressure on the database we do not query it when setting labels and +milestones on issues and merge requests. Instead we cache this data when we +import labels and milestones, then we reuse this cache when assigning them to +issues/merge requests.
