Deleting the memberships with delete_all skips Membership's after_destroy_commit, which resets a member's connections when one membership is revoked. Until the job ran, a member who had the room open kept its streams, and a message that still landed in the room (a request already past the membership check, a bot's reply) reached them. The request now reads the members' ids in the transaction that deletes their memberships, and the job resets their connections before it destroys the messages. It costs a Redis round trip per member, about 1.5 s for 10,000, so it's done in the job rather than in the request. User#grant_membership_to_open_rooms read the open rooms and inserted in a separate statement, so a user created while a room was being closed could read it as open and be granted it after the close. It's now a single insert ... select, which SQLite runs under the write lock, skipping duplicates as insert_all did.

Campfire
Campfire is a web-based chat application. It supports many of the features you'd expect, including:
- Multiple rooms, with access controls
- Direct messages
- File attachments with previews
- Search
- Notifications (via Web Push)
- @mentions
- API, with support for bot integrations
Running your own Campfire instance
Campfire's Docker image contains everything needed for a fully-functional,
single-machine deployment. This includes the web app, background jobs, caching,
file serving, and SSL. You can use our pre-built image at
ghcr.io/basecamp/once-campfire:latest, or build your own from this repo.
Deploying with ONCE
The easiest way to self-host Campfire is with ONCE. It will guide you through the initial set up and then keep your instance up to date automatically.
If you don't already have once installed, run this on the machine you want to run Campfire on:
curl https://get.once.com | sh
once will launch as soon as the install is finished.
Choose Campfire from the list of applications, follow the instructions, and ONCE will take care of the rest.
If you prefer the command line to the dashboard, you can deploy directly:
once deploy ghcr.io/basecamp/once-campfire --host chat.example.com
Deploying with Docker
If you'd rather run the Docker image yourself, you can read more about that in the self-hosting guide.
Tip
When you start Campfire for the first time, you'll be guided through a wizard to create an admin account. The email address that you enter for the admin account will be visible on the sign-in page, it's there so that people have someone to contact if they need help with their account. If that bothers you, put in any email address you want and create yourself a new admin account.
