mod_firewall: Update user marks to store instantly via map store The original approach was to keep marks in memory only, and persist them at shutdown. That saves I/O, at the cost of potentially losing marks on an unclean shutdown. This change persists marks instantly, which may have some performance overhead but should be more "correct". It also splits the marking/unmarking into an event which may be watched or even fired by other modules.

summary: 'Require MUC occupant nicknames to match a specific pattern'
---

Introduction
============

This checks the nickname of a joining user against a configurable
[Lua pattern](https://www.lua.org/manual/5.2/manual.html#6.4.1), and prevents
them from joining if it does not match.

Configuration
=============

There is a single configuration option, `muc_restrict_nick_pattern` and the
default is `"^%w+$"` - i.e. allow only alphanumeric characters in nicknames.

Compatibility
=============

Requires Prosody 0.11 or higher.
