Adds topic tracking: a TopicChange event (parsed from InspIRCd FTOPIC, our own
changes filtered by SID like FMODE) and a stored topic on the channel, folded
through the event log. TOPICLOCK reverts a topic change by a user without
op-level access back to the stored topic; KEEPTOPIC remembers the topic and
restores it when a registered channel is recreated. Both via the typed
ChanSettings path; shown in INFO. Parse + engine tests cover both.
When SECUREOPS is on, a user who gains channel-operator status without op-level
access is immediately deopped. Enforced in the engine's ChannelOp hook (manual
FMODE +o) and the Join hook (FJOIN prefix ops), sourced from ChanServ. Same
typed-settings path; shown in INFO; engine test covers on and off.
PEACE stops a channel op from using ChanServ KICK/BAN/DEOP/DEVOICE against
someone whose access rank (founder>op>voice) is equal to or above their own.
Adds a typed access_rank on ChannelView and a peace_blocks guard in those
commands. Same typed-settings path as SIGNKICK/PRIVATE; shown in INFO.
Introduce a typed ChanSettings struct + ChanSetting enum for ChanServ's on/off
options instead of a bag of string flags, so a new option is one field and the
compiler proves every site handles it. First two, both functional: SIGNKICK
attributes ChanServ kicks with who requested them; PRIVATE hides the channel
from LIST. Folded through the event log like the other channel state (node-local,
no gossip), shown in INFO. One ChannelSettingsSet event, one Store method.
Three brute-force / weak-secret gaps closed:
- REGISTER and SET PASSWORD now enforce a length range and reject a password
equal to the nick (Anope's minpasslen/not-nick rules), with tests.
- IDENTIFY is throttled per account: a few free tries then an exponential
backoff that clears on success, so a password can't be ground down. SASL had
a limiter; interactive login had none.
- Emailed confirm/reset codes go from 6 digits to 8 base32 chars (~40 bits) and
are burned after a few wrong guesses, closing a reset-code takeover window.
Throttle and code state are node-local and in-memory (not in the event log).
Adds the account auto-join list (AJOIN ADD/DEL/LIST): NickServ SVSJOINs you
into your listed channels each time you identify. The list is a typed
Vec<AjoinEntry> on the account, folded through the event log like the cert and
akick lists (persists and replays; no separate store), reached by modules
through the Store trait. New ForceJoin action serialises to InspIRCd SVSJOIN.
Shown in INFO. Operates on the caller's own account; the oper form for other
users waits on a privilege system.
nickserv, chanserv and the InspIRCd protocol move out of the binary into their
own workspace crates (fedserv-nickserv, fedserv-chanserv, fedserv-inspircd),
each depending only on fedserv-api. human_time and the branded account emails
move into the SDK crate so a module needs nothing from core; the engine keeps
its own inherent methods and builds emails via fedserv-api too. The bin now
constructs each module from its crate instead of an in-tree #[path] include.
Proves the SDK is self-sufficient: a third-party module is the same shape.
Services no longer receive the concrete account store. on_command now takes
&mut dyn Store + &dyn NetView (both defined in fedserv-api); the engine's Db
and Network implement them. Reads hand back plain views (AccountView,
ChannelView, ...) carrying only non-secret fields, so the event log, gossip,
and credential material (password hash, SCRAM verifiers) are unreachable from
a module. All command modules ported; behaviour unchanged.
Move NetEvent/NetAction/RegReply/Protocol and Sender/ServiceCtx into a
dependency-free fedserv-api crate that a module builds against. Core keeps
referring to them through re-export shims at crate::proto and
crate::engine::service, so no consumer changes. Groundwork for external
service and protocol modules.
