libreircd - simple IRCd

Age	Commit message (Collapse)	Author
13 days	Allow lf as well as crlf	Nakidai
	For configuration it's important to allow IRC messages to end with \n. This also fixes a TODO from a previous commit and allows to connect to ircd using netcat
13 days	Add WHOIS and config parsing	Nakidai
	Now users can query each other Plus, server info and creation date can be changed without recompiling using configuration file in IRC message format which is loaded on startup TODO: since readcfg uses IRC logic, handle() now should be able to deal with commands ending with simply \n
2026-02-01	Fixes	Nakidai
	- Now code depends on config.h in Makefile - By default the smallest timeout is chosen for poll() - Somewhy there was sizeof(PEER_QUIT_MAX)...
2026-02-01	Added copyright notice to the config.h	Nakidai
	Well, example config values don't need licesing that much, but as every other file has that notice I think this one should have it as well
2026-02-01	Enhance registration messages	Nakidai
	Now ircd responds with all replies up to 4 Plus memchr was wrong, yep
2026-02-01	Update README	Nakidai
	It wasn't very accurate for this time
2026-02-01	Add validation	Nakidai
	Now there can't be single \r or \n in the message, erroneous nicks and channel names are rejected, and usernames are stripped on '@'
2026-02-01	Fix all the warnings	Nakidai
	The one in user.c is the funniest one
2026-02-01	Refactor QUIT message sending	Nakidai
	After seeing same announcing code second time I decided it should be done before an actual quit in loop.c. Plus, channel exiting is now done in user_remove().
2026-02-01	Add exiting from a channel in user_remove	Nakidai
	I think it should guarantee that nothing will break, including chanels
2026-02-01	Add ping system	Nakidai
	Now users will be kicked for inactivity o.o
2026-02-01	Remove magic numbers from ircd.h	Nakidai
	Also make a new file config.h for storing that stuff
2026-01-30	Add PING command v0.1.0	Nakidai
	Then I should make some logic for pinging others...
2026-01-30	Add support for NOTICE	Nakidai
	Well, it's the same as PRIVMSG but different name
2026-01-30	Invert the logic in nick()	Nakidai
	Well... yes
2026-01-30	Simplify join command	Nakidai Perumenei
	- Instead of checking users in the channel check user's channels - Ensure thing looks really dumb here, so remove it
2026-01-30	Add nickname change announcement	Nakidai Perumenei

2026-01-30	Add self announcing	Nakidai Perumenei
	If user hasn't joined any channels, announcement still should be delivered to them
2026-01-30	Move announcing code to writef.c	Nakidai Perumenei
	Well, I guess that code is needed more then once, so it'll be good to move it to some function
2026-01-30	Fix channel remove	Nakidai Perumenei
	Channels are removed just like users, hence they have the same problem as users had before: when channel is removed, links to it must be updated. For users that was fixed[1], for users this commit provides the fix. [1] Commit where user quit was fixed - 63c0a8860459c0c9bf3b66d4d4ec631ece4bf56e
2026-01-30	Add nickname checking	Nakidai Perumenei
	Yay, adding some validation to the data ^^
2026-01-30	Speed up user removing	Nakidai
	Now it's O(n) instead of O(n^2)
2026-01-29	Simplify client's buffer overflow	Nakidai
	So I decided to kill a link when there's no IRC message within 512 bytes, because doing so removes code and IMO makes it more clear If peer->recvd == sizeof(peer->buf), then buffer size passed into next read(peer->fd) will be 0, therefore its return value will be 0. Though, this means that link is almost dropped if it sent exactly 512 bytes not containing an \r\n: they can get information, but on next send ircd will close the connection. But this state is unachievable with an IRC client: it either sends a message <= 512 bytes containing an \r\n, or, if one or more bytes longer, well that's already > 512 bytes hence link is still ready to be read and will be kicked after the next poll()
2026-01-12	Implement 443	Nakidai

2026-01-10	Check whether user was registered or not in user_reg()	Nakidai
	So, it fixes a situation when an already registered user wants to change their nick and ircd welcomes they
2026-01-10	Add basic user mode handling	Nakidai
	So, now there're all modes listed in RFC 2812. The only what they do now, though, is a +r restricting user from changing their nick
2026-01-10	Make all files dependent on ircd.h	Nakidai
	There were bugs when struct layout was changed, and this was right because needed files were not rebuilt. This is fixed now
2026-01-10	Simplify pledge	Nakidai
	In the past there was a configpath parameter, and unveil was allowing to read at this path. But now accessing filesystem is redundant completely
2026-01-07	Add comments for some macros	Nakidai

2026-01-07	Use function with switch() in reply.c	Nakidai
	Overall, this solution looks better. Also, now macro is better
2026-01-07	Move quit announcement code to quit()	Nakidai
	Well, it's more appropriate for that function to handle this rather than for ircd(). Now code looks simpler, ircd() is not that complex, and support for optional quit message is present
2026-01-07	Fix user quit	Nakidai
	When user A leaves, last user in the peer list B is copied into the space left by leaving A. But, besides that it also important to not forget that there can be channels containing B: they store a link to every user belonging. So, it's important to adjust all links to B iterating every channel B belongs to.
2026-01-06	Replace for (;;) with goto	Nakidai
	It reduces indentation, which was quite pointless in that loop
2026-01-06	Use strtoul instead of strtod	Nakidai
	I really thought strtod was converting to integers...
2026-01-06	Add basic channels	Nakidai
	Though they don't have modes, and JOIN/PART must be able to parse comma separated list of channels
2026-01-04	Add code	Nakidai
