Asher fc7700a62f fix: improve reliability of app statuses (#18622)
We were discarding all "working" updates from the screen watcher because
we cannot tell the difference between the agent or user changing the
screen, but it makes sense to accept it as the very first update,
because the agent could be working but neglected to report that fact, so
you would never get an initial "working" update (it would just
eventually go straight to "idle").

Also messages can start at zero, so I made a fix for that as well,
although the first message will be from the LLM and we ignore
those anyway, so this probably has no actual effect, but seems more
technically correct.

And it seems I forgot to actually update the last message ID, which 
also does not actually matter for user messages (since I think the
SSE endpoint will not re-emit a user message it has already emitted),
but seems more technically correct to check.

Lastly, if we have the screen watcher, ignore the agent's self-reported
state and always use "working" since it is unreliable.  The idle state will
eventually be caught by the watcher.

Coder enables organizations to set up development environments in their public or private cloud infrastructure. Cloud development environments are defined with Terraform, connected through a secure high-speed Wireguard® tunnel, and automatically shut down when not used to save on costs. Coder gives engineering teams the flexibility to use the cloud for workloads most beneficial to them.

  • Define cloud development environments in Terraform
    • EC2 VMs, Kubernetes Pods, Docker Containers, etc.
  • Automatically shutdown idle resources to save on costs
  • Onboard developers in seconds instead of days

Quickstart

The most convenient way to try Coder is to install it on your local machine and experiment with provisioning cloud development environments using Docker (works on Linux, macOS, and Windows).

# First, install Coder
curl -L https://coder.com/install.sh | sh

# Start the Coder server (caches data in ~/.cache/coder)
coder server

# Navigate to http://localhost:3000 to create your initial user,
# create a Docker template and provision a workspace

Install

The easiest way to install Coder is to use our install script for Linux and macOS. For Windows, use the latest ..._installer.exe file from GitHub Releases.

curl -L https://coder.com/install.sh | sh

You can run the install script with --dry-run to see the commands that will be used to install without executing them. Run the install script with --help for additional flags.

See install for additional methods.

Once installed, you can start a production deployment with a single command:

# Automatically sets up an external access URL on *.try.coder.app
coder server

# Requires a PostgreSQL instance (version 13 or higher) and external access URL
coder server --postgres-url <url> --access-url <url>

Use coder --help to get a list of flags and environment variables. Use our install guides for a complete walkthrough.
