* Check a cable connection's session while it's open
Signing out or changing the password ends sessions and then disconnects
their connections. A connection that found its session just before isn't
subscribed to its disconnects yet, so it missed that and stayed open.
Each connection now looks its session up every minute while it's open, and
closes once the session is gone, asking the browser to reconnect so one
holding a current session comes back. That also covers any other way a
connection misses the disconnect, such as a subscription that takes long to
register, and a lookup that fails is simply tried again.
* Check the session on the server's heartbeat rather than a timer of its own
A connection's own timer could outlive it: closing can run before opening finishes, or a channel's teardown can fail before the connection's. The heartbeat only reaches connections that are open, so nothing is left to stop.
* Skip the session check on a rejected connection
A rejected connection stays registered until its socket closes, and has no session to check, so its heartbeat mustn't fail and stop the heartbeat reaching the connections after it.

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.
