mod_graceful_shutdown

This module is an experiment about a more graceful shutdown process.

Graceful shutdown has now been implemented in Prosody trunk and will be part 0.12. See issue #1225 for details.

Why

When shutting down, a number of sessions, connections and other things are teared down. Due to all these things happening very quickly, sometimes e.g. client unavailable notifications don’t make it to all remote contacts because the server-to-server connections are teared down just after.

How

This module works by breaking the shutdown process into separate steps with a brief pause between them.

It goes something like this

  1. Stop accepting new client connections.
  2. Close all client connections.
  3. Fire event for everything else.
  4. Tell net.server to quit the main loop.
  5. ???
  6. Still here? Kill itself.

Installation

With the plugin installer in Prosody 0.12 you can use:

sudo prosodyctl install --server=https://modules.prosody.im/rocks/ mod_graceful_shutdown

For earlier versions see the documentation for installing 3rd party modules
