Stats now have their own service. StatServ answers /msg StatServ <#channel>
(per-channel activity — lines + top talkers, founder-or-admin) and
/msg StatServ SERVER (the shared cross-service counter registry + gauges,
operators only). The shared counter map moved from the engine onto the
network view so both StatServ (via NetView::stat_counters) and the gRPC
Stats API read one source. BotServ's BOTSTATS command is removed; the
per-channel activity is still recorded in the dispatch loop.
BOTSTATS <#channel> reports the lines the bot has seen this session and
the top talkers. Tracked live in the network view (bounded per-nick map),
recorded for bot-assigned channels only, and also fed to the shared stats
registry as botserv.messages.
TRIGGER <#channel> ADD <regex>|<response> | DEL <num> | LIST | CLEAR: when
a channel line matches <regex>, the assigned bot says <response> ($nick
becomes the speaker's nick). Only the first matching trigger fires, and a
line the bot just kicked for gets no response.
Same engine machinery as badwords: patterns compile into one RegexSet per
channel (linear-time, ReDoS-safe), cached and rebuilt only on a revision
change. Patterns validated + size-limited at add time.
Copies a channel's kickers, badword list, greet and nobot settings onto
another channel (founder-or-admin on both). Cheap because the config is a
typed KickerSettings + Vec<String>, not a bag of stringly extensibles.
BADWORDS <#channel> ADD|DEL|LIST|CLEAR manages a channel's badword
patterns, each a regular expression, so a channel matches whatever it
wants — an improvement over Anope's fixed ANY/SINGLE/START/END. Enable
with KICK <#channel> BADWORDS ON.
Uses the regex crate: it's finite-automata based with linear-time
matching, so untrusted user patterns can't cause catastrophic
backtracking (ReDoS). A channel's patterns compile into one RegexSet
(single-pass match against all of them), cached in the engine and rebuilt
only when the list's revision changes — so the hot path is one is_match
call, no per-message compilation or allocation. Patterns are validated
(and size-limited) at add time; matching is case-insensitive by default.
The assigned bot now enforces kickers on channel lines: KICK <#channel>
CAPS ON [min [percent]], and BOLDS/COLORS/UNDERLINES/REVERSES/ITALICS
for control-code formatting. DONTKICKOPS exempts channel operators. A
tripping line is kicked by the bot itself.
Kicker config is a typed KickerSettings struct on the channel (event-
sourced like ChanSettings) with a violation() check; the engine runs it
on every channel PRIVMSG. Factored the founder-or-admin gate into a
shared require_channel_admin helper (assign/set/kick).
Members set a personal greet with NickServ SET GREET; a channel founder
enables display with BotServ SET <#channel> GREET ON. On join, if greets
are enabled and the member has channel access and a non-empty greet, the
assigned bot shows [account] greet in the channel.
Per-account greet is a typed field on Account (AccountGreetSet event, rides
the account snapshot); the per-channel toggle is a new ChanSetting::BotGreet
bool. Greet is public in NickServ INFO.
The channel's assigned bot can now speak: SAY <#channel> <text> and ACT
<#channel> <text> (CTCP ACTION), gated on channel-operator access. Bots
are tracked in the network view so uid_by_nick resolves them, and the
message is sourced from the bot's own uid via a new ServiceCtx::privmsg.
INFO <bot> describes a bot and lists the channels it serves; INFO
<#channel> shows which bot is assigned to a channel. Own file, wired
into the dispatcher.
Match the NickServ/ChanServ layout: lib.rs keeps only the service struct
and the on_command dispatcher, and each command moves to its own file
bridged with #[path]. No behaviour change.
BotServ: bot.rs, assign.rs.
MemoServ: send.rs, list.rs, read.rs, del.rs.
A channel gains a typed assigned_bot (event-logged, snapshotted). ASSIGN
<#channel> <bot> / UNASSIGN <#channel> is founder-gated (or admin oper). The
engine reconcile now also diffs channel assignments against tracked bot
memberships: a live bot IJOINs its assigned channels and PARTs unassigned ones
(new ServiceJoin/ServicePart actions), at burst and after commands; a deleted
bot's memberships are dropped. Engine test for join-on-assign / part-on-unassign.
Adds BotServ as a new module crate (fedserv-botserv) and a persisted bot
registry: a typed Bot{nick,user,host,gecos} threaded through the event log
(new bots map folded in apply, snapshotted, Local scope). BOT ADD/DEL/LIST
gated on the typed Priv::Admin. BotServ is a default service (uid suffix
AAAAAD). Next slices: introduce bots on the network, ASSIGN to channels, and
in-channel fantasy commands. Data + oper-gated engine tests.
