ergochat/ergo v0.1.0

Initial Release

on GitHub

Somewhat of an initial release! This version still has lots of bugs and lots of functionality to rewrite, but there's a lot of useful changes from upstream.

Change notes:

Security

• PROXY command is now restricted appropriately.
• Nicknames, usernames and channel names that break the protocol are no longer allowed.
• Default channel modes set to restrict new channels more appropriately by default.

Added

• YAML config file format.
• buntdb key-value store for persistent data.
• Native SSL/TLS support (thanks to @Edmand).
• Ability to generate testing certificates from the command line.
• Support for looking up usernames with ident on client connection.
• RPL_ISUPPORT numeric as advertised by most other IRCds today.
• Ability to parse complex mode change syntax commonly used these days (i.e. +h-ov dan dan dan).
• User mode for clients connected via TLS (+Z).
• Ability to register and login to accounts (with passphrase or certfp).
• Support for IRCv3 capabilities account-tag, away-notify, extended-join, sasl, server-time, and userhost-in-names.

Changed

• Channel creator (O) privilege changed to founder/admin/halfops (qah) privileges.
• Private (+p) channel mode changed to secret (+s), to match what's used by servers today.
• Default channel modes changed to (+nt), matching most other IRCds.
• CLI commands and arguments made more consistent with typical software.
• Usernames set by the USER command now start with "~" (to work with new ident support).
• Renamed ONICK command to SANICK to be more consistent with other IRCds.
• Made maximum nickname and channel name lengths configurable.
• Made maximum WHOWAS entries configurable.

Removed

• Removed gitconfig configuration format [replaced with YAML].
• Removed sqlite database [replaced with buntdb key-value store].
• Removed THEATER command (it broke and I'm not that interested in putting the work in to get it working again with the aim of this project. PRs accepted).

Fixed

• Fixed clients no longer being able to send commands after a single command errored out.
• CAP: Registration is now properly suspended during CAP negotiation.
• CAP: Remove CAP CLEAR (recommended in IRCv3 3.2), and allow capability negotiation after registration.
• MODE: Fixed <modestring> evaluation (we were parsing all ungrabbed parameters as a modestring, when it is actually only the first param).
• MODE: New-style mode change syntax (with both adding and removing modes in a single MODE command) is now parsed properly.
• MOTD: Now store MOTD in-memory rather than on-disk, and don't limit it to 80 characters per line (not required with today's servers or clients).
• NICK: Restrict nicknames that break the protocol.
• USER: Restrict usernames that break the protocol.
• PROXY: Restrict to specified hostnames only.
• WHOIS: Include the required <nick> param on RPL_ENDOFWHOIS.
• WHOIS: Hide hidden channels in WHOIS responses.
