A stateless service for tabletop games over IRC. ROLL/CALC evaluate a dice
+ math expression (ROLL rounds to a whole number, CALC keeps decimals);
EXROLL/EXCALC also show each die. Supports NdM / dM / d% dice, + - * / ^ %,
parentheses, implicit multiplication, unary minus, pi/e, a set of functions
(sqrt, floor, sin, min, …), and N~expr to repeat a roll.
Modernises the C++ original: it ships its own Mersenne-Twister RNG in C
and parses via shunting-yard with a variadic-argument hack; this is a
typed AST from a small recursive-descent parser plus the rand crate —
shorter, and the dice/sides/total caps make abuse (999999d6) a clean error
instead of a hang. Opt-in (add "diceserv" to [modules].services).
The first operator module. AKILL manages network bans as a typed,
event-sourced list with lazy expiry, mirroring the patterns the other
modules use:
- AKILL ADD [+expiry] <user@host> <reason> stores the ban and drives an
ircd G-line (applied to matching users already online and to future
connections); AKILL DEL <mask|number> lifts it; AKILL LIST [pattern]
shows the live list, numbered. Admin-only.
- Bans are Global events, so every node holds the list and re-asserts each
one at burst with its remaining duration. Expired bans are hidden lazily
and dropped at compaction.
- Masks are normalised to user@host (a nick! prefix is stripped, both
sides lowercased) and an all-wildcard mask is refused.
Email (send_email) is already reachable from the api via ServiceCtx, and
adds AddLine/DelLine to the action vocabulary for any future X-line kinds.
New HostServ pseudo-service assigns and applies vhosts. A vhost is a typed
Option<Vhost>{host,setter,ts} on the account (VhostSet/VhostDeleted events),
applied to the displayed host on identify and re-applied by ON; OFF restores
the normal host for the session. Operators SET/DEL (applied at once to
online sessions) and LIST; hosts are validated as dot-separated labels.
New SetHost NetAction -> InspIRCd ENCAP <target-sid> CHGHOST <uid> <host>.
[jsonrpc].tls = { cert, key } makes the endpoint terminate TLS itself,
which also enables HTTP/2 (ALPN), so traffic is encrypted right up to
fedserv — for when it runs on a different host from the site, or the
browser's TLS should reach it directly. Absent = plain HTTP for a
reverse-proxy front. Reuses the same cert/key shape as [grpc]; a crypto
provider is pinned before building the config (the tree carries more than
one). Verified the TLS config builds against a real cert without a
provider panic.
Plain HTTP + JSON-RPC 2.0 (axum, already in the tree) so a site backend
can pull stats without gRPC stubs. Methods: stats.get (counters + gauges)
and stats.channel { channel } (lines + top talkers). Optional [jsonrpc]
config, off unless set.
Security: bearer-token authenticated with a constant-time compare, refuses
to start with an empty token, read-only (only stats.* methods — no way to
mutate state), method-allowlisted, a 64 KiB body limit, and meant to bind
to localhost beside the backend.
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.
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.
Finish MemoServ on the typed, event-logged memo model: Db memo_send/list/read/
del/unread_memos + Store facade, and a new fedserv-memoserv crate (a default
service). Beyond the basics: SEND caps a mailbox (30) so nobody's flooded, READ
takes <num>|NEW|ALL, DEL takes <num>|ALL, LIST previews and flags unread, and
NickServ notifies you of waiting memos on login. Memos persist and federate
(Global scope) like other account data. Also lands NetAction::QuitUser (BotServ
plumbing). Data + delivery/login-notify tests.
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.
A [modules] block selects which services start (default: NickServ + ChanServ);
main.rs constructs each compiled-in module only when named, so a node can run a
subset and optional modules ship dormant. Add fedserv-example, a minimal
read-only Service that depends on fedserv-api alone -- the template a new
pseudo-client is copied from, enabled by adding "example" to the config.
MODULES.md documents writing and registering a service or protocol module.
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.
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.
Snapshot (full read) + Subscribe (live stream) over the same committed-entry
channel gossip uses. Identity and metadata only — password hashes, SCRAM
verifiers, cert fingerprints, and the finer channel-ops-list events never
cross this API. Bearer-token authenticated, optional server TLS. Verified
end-to-end against a live test-net registration, not just unit tests.
Adds a config-driven mailer: a SendEmail action the link layer pipes to
a configured command (sendmail -t, msmtp, ...) off-thread. NickServ
RESETPASS <account> emails a short-lived code to the address on file;
RESETPASS <account> <code> <newpassword> completes the reset. Codes are
node-local; the password change itself federates.
Optional [gossip.tls] wraps the peer link in TLS: each node presents a
certificate and requires the peer to present one signed by the configured
CA. scripts/gen-certs.sh builds a CA and node certs.
fedserv now handles the SASL exchange an ircd relays over ENCAP (modes H/S/C/D):
on PLAIN it answers the empty challenge, decodes the client payload, and verifies
the credentials against the account store, replying D S or D F. Wiring the
account login on success and advertising the mechanism list to the ircd are the
remaining integration steps.
Accounts are an append-only JSONL event log (state is the fold of the log) with
argon2id-hashed passwords. NickServ gains REGISTER <password> [email] and
IDENTIFY <password>; the engine tracks UID->nick from the burst so a command
resolves to the sender's current nick. Classic and ircd-agnostic — the cap-based
account-registration forward is the next step.
Protocol-agnostic core: a Protocol trait maps raw server-to-server lines to a
normalized event/action model, so the engine never touches a raw line and a new
ircd is one new module. Adds event-log state (state is a fold over the log) and
a service framework. First protocol impl links to an InspIRCd (insp4) uplink —
completes the CAPAB/SERVER handshake, bursts, and introduces NickServ.
