* Don't delete the user's favorites unless private favorites are enabled. The general rule is that public account activity is kept and private account activity is deleted. * Delete the user's API keys, forum topics visits, private favgroups, downvotes, and upvotes (if privacy is enabled). * Reset all of the user's account settings to default. This means custom CSS is deleted, where it wasn't before. * Delete everything but the user's name and password asynchronously. * Don't log the current user out if it's the owner deleting another user's account. * Fix #5067 (Mod actions sometimes not created for user deletions) by wrapping the deletion process in a transaction.
Jobs
This directory contains background jobs used by Danbooru. Jobs are used to handle slow-running tasks that need to run in the background, such as processing uploads or bulk update requests. They're also used for asynchronous tasks, such as sending emails, that may temporarily fail but can be automatically retried later.
Jobs use the Rails Active Job framework. Active Job is a common framework that allows jobs to be run on different job runner backends.
In the production environment, jobs are run using the Good Job backend. Jobs
are stored in the database in the good_jobs table. Worker processes spawned
by bin/good_job poll the table for new jobs to work.
In the development environment, jobs are run with an in-process thread pool. This will run jobs in the background, but will drop jobs when the server is restarted.
There is a very minimal admin dashboard for jobs at https://danbooru.donmai.us/jobs.
Danbooru also has periodic maintenance tasks that run in the background as cron jobs. These are different from the jobs in this directory. See app/logical/danbooru_maintenance.rb.
Usage
Start a pool of job workers:
RAILS_ENV=production bin/good_job start --max-threads=4
Examples
Spawn a job to be worked in the background. It will be worked as soon as a worker is available:
DeleteFavoritesJob.perform_later(user)
