Merge branch 'main' into feature/irc-numerics-batch2

fix: IRC SPA cleanup — /motd, /query, Firefox / key, default MOTD (#58 )
## Summary Fixes IRC client SPA issues reported in [issue #57](#57). ## Changes ### Server-side - **Default MOTD**: Added figlet-style ASCII art MOTD for "neoirc" as the default when no MOTD is configured via environment/config - **MOTD command handler**: Added `MOTD` case to `dispatchCommand` so clients can re-request the MOTD at any time (proper IRC behavior) ### SPA (web client) - **`/motd` command**: Sends MOTD request to server, displays 375/372/376 numerics in server window - **`/query nick [message]`**: Opens a DM tab with the specified user, optionally sends a message - **`/clear`**: Clears messages in the current tab - **Firefox `/` key fix**: Added global `keydown` listener that captures `/` when input is not focused, preventing Firefox quick search and redirecting focus to the input element. Also auto-focuses input on SPA init. - **MOTD on resumed sessions**: When restoring from a saved token, the MOTD is re-requested so it always appears in the server window - **Updated `/help`**: Shows all new commands with descriptions - **Login screen MOTD styling**: Improved for ASCII art display (monospace, proper line height) ## Testing - `docker build .` passes (includes `make check` with tests, lint, fmt-check) - All existing tests pass with no modifications closes #57  Co-authored-by: user <user@Mac.lan guest wan> Reviewed-on: #58 Co-authored-by: clawbot <clawbot@noreply.example.org> Co-committed-by: clawbot <clawbot@noreply.example.org>

-returns standard HTTP error responses (4xx/5xx with JSON error bodies) instead
-of numeric replies for error conditions. Numeric replies in the message queue
-will be added post-MVP.

clawbot	47fb089969	fix: IRC SPA cleanup — /motd, /query, Firefox / key, default MOTD (#58 ) All checks were successful check / check (push) Successful in 1m0s Details ## Summary Fixes IRC client SPA issues reported in [issue #57](#57). ## Changes ### Server-side - Default MOTD: Added figlet-style ASCII art MOTD for "neoirc" as the default when no MOTD is configured via environment/config - MOTD command handler: Added `MOTD` case to `dispatchCommand` so clients can re-request the MOTD at any time (proper IRC behavior) ### SPA (web client) - `/motd` command: Sends MOTD request to server, displays 375/372/376 numerics in server window - `/query nick [message]`: Opens a DM tab with the specified user, optionally sends a message - `/clear`: Clears messages in the current tab - Firefox `/` key fix: Added global `keydown` listener that captures `/` when input is not focused, preventing Firefox quick search and redirecting focus to the input element. Also auto-focuses input on SPA init. - MOTD on resumed sessions: When restoring from a saved token, the MOTD is re-requested so it always appears in the server window - Updated `/help`: Shows all new commands with descriptions - Login screen MOTD styling: Improved for ASCII art display (monospace, proper line height) ## Testing - `docker build .` passes (includes `make check` with tests, lint, fmt-check) - All existing tests pass with no modifications closes #57 <!-- session: agent:sdlc-manager:subagent:7c880fec-f818-49ff-a548-2d3c26758bb6 --> Co-authored-by: user <user@Mac.lan guest wan> Reviewed-on: #58 Co-authored-by: clawbot <clawbot@noreply.example.org> Co-committed-by: clawbot <clawbot@noreply.example.org>	2026-03-09 23:00:34 +01:00
clawbot	df82c6b302	feat: implement IRC numerics batch 2 — connection registration, channel ops, user queries All checks were successful check / check (push) Successful in 2m50s Details Add comprehensive IRC numeric reply support: Connection registration (001-005): - 002 RPL_YOURHOST, 003 RPL_CREATED, 004 RPL_MYINFO, 005 RPL_ISUPPORT - All sent automatically during session creation after RPL_WELCOME Server statistics (251-255): - RPL_LUSERCLIENT, RPL_LUSEROP, RPL_LUSERCHANNELS, RPL_LUSERME - Sent during connection registration and via LUSERS command Channel operations: - MODE command: query channel modes (324 RPL_CHANNELMODEIS, 329 RPL_CREATIONTIME) - MODE command: query user modes (221 RPL_UMODEIS) - NAMES command: query channel member list (353/366) - LIST command: list all channels (322 RPL_LIST, 323 end of list) User queries: - WHOIS command: 311/312/318/319 numerics - WHO command: 352 RPL_WHOREPLY, 315 RPL_ENDOFWHO Database additions: - GetChannelCount, ListAllChannelsWithCounts - GetChannelCreatedAt, GetSessionCreatedAt Also adds StartTime to Globals for RPL_CREATED and updates README with comprehensive documentation of all new commands and numerics. closes #52	2026-03-09 14:53:49 -07:00
clawbot	f8f0b6afbb	refactor: replace HTTP error codes with IRC numeric replies (#56 ) All checks were successful check / check (push) Successful in 58s Details ## Summary Refactors all IRC command handlers to respond with proper IRC numeric replies via the message queue instead of HTTP status codes. HTTP error codes are now reserved exclusively for transport-level concerns: - 401 — missing/invalid auth token - 400 — malformed JSON, empty command - 500 — server errors ## IRC Numerics Implemented ### Success replies (delivered via message queue on success): - 001 RPL_WELCOME — sent on session creation and login - 331 RPL_NOTOPIC — channel has no topic (on JOIN) - 332 RPL_TOPIC — channel topic (on JOIN, TOPIC set) - 353 RPL_NAMREPLY — channel member list (on JOIN) - 366 RPL_ENDOFNAMES — end of NAMES list (on JOIN) - 375/372/376 — MOTD (already existed) ### Error replies (delivered via message queue instead of HTTP 4xx): - 401 ERR_NOSUCHNICK — DM target not found (was HTTP 404) - 403 ERR_NOSUCHCHANNEL — channel not found / invalid name (was HTTP 404) - 421 ERR_UNKNOWNCOMMAND — unrecognized command (was HTTP 400) - 432 ERR_ERRONEUSNICKNAME — invalid nick format (was HTTP 400) - 433 ERR_NICKNAMEINUSE — nick taken (was HTTP 409) - 442 ERR_NOTONCHANNEL — not a member of channel (was HTTP 403) - 461 ERR_NEEDMOREPARAMS — missing required fields (was HTTP 400) ## Database Changes - Added `params` column to messages table for IRC-style parameters - Added `Params` field to `IRCMessage` struct - Updated `InsertMessage` to accept params ## Test Updates - All existing tests updated to expect HTTP 200 + IRC numerics - New tests: `TestWelcomeNumeric`, `TestJoinNumerics` ## Client Impact - CLI and SPA already handle unknown numerics via default event handlers - PRIVMSG/NOTICE success changed from HTTP 201 to HTTP 200 closes #54 Co-authored-by: clawbot <clawbot@noreply.git.eeqj.de> Co-authored-by: Jeffrey Paul <sneak@noreply.example.org> Reviewed-on: #56 Co-authored-by: clawbot <clawbot@noreply.example.org> Co-committed-by: clawbot <clawbot@noreply.example.org>	2026-03-09 22:21:30 +01:00
