Move all substantive CLI code (app logic, UI, API client,
hashcash, types) from cmd/neoirc-cli/ to internal/cli/.
The cmd/neoirc-cli/main.go now contains only minimal
bootstrapping that calls cli.Run().
This follows the project convention that cmd/ should only
contain minimal main() bootstrapping code.
Add SHA-256-based hashcash proof-of-work requirement to POST /session
to prevent abuse via rapid session creation. The server advertises the
required difficulty via GET /server (hashcash_bits field), and clients
must include a valid stamp in the X-Hashcash request header.
Server-side:
- New internal/hashcash package with stamp validation (format, bits,
date, resource, replay prevention via in-memory spent set)
- Config: NEOIRC_HASHCASH_BITS env var (default 20, set 0 to disable)
- GET /server includes hashcash_bits when > 0
- POST /session validates X-Hashcash header when enabled
- Returns HTTP 402 for missing/invalid stamps
Client-side:
- SPA: fetches hashcash_bits from /server, computes stamp using Web
Crypto API with batched SHA-256, shows 'Computing proof-of-work...'
feedback during computation
- CLI: api package gains MintHashcash() function, CreateSession()
auto-fetches server info and computes stamp when required
Stamp format: 1:bits:YYMMDD:resource::counter (standard hashcash)
closes #11
## 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

## Changes
- Change `Appname` from `"chat"` to `"neoirc"` in `cmd/chatd/main.go`
- Change default `DBURL` from `file:./data.db?_journal_mode=WAL` to `file:///var/lib/neoirc/state.db?_journal_mode=WAL` in both `internal/config/config.go` and the `internal/db/db.go` fallback
- Create `/var/lib/neoirc/` directory in Dockerfile with proper ownership for the `chat` user
- Update README.md to reflect new defaults (DBURL table, `.env` example, docker run example, SQLite backup/location docs)
- Remove stale `data.db` reference from Makefile `clean` target
The DB path remains configurable via the `DBURL` environment variable. No Go packages were renamed.
Closes #44

Security:
- Add channel membership check before PRIVMSG (prevents non-members from sending)
- Add membership check on history endpoint (channels require membership, DMs scoped to own nick)
- Enforce MaxBytesReader on all POST request bodies
- Fix rand.Read error being silently ignored in token generation
Data integrity:
- Fix TOCTOU race in GetOrCreateChannel using INSERT OR IGNORE + SELECT
Build:
- Add CGO_ENABLED=0 to golangci-lint install in Dockerfile (fixes alpine build)
Linting:
- Strict .golangci.yml: only wsl disabled (deprecated in v2)
- Re-enable exhaustruct, depguard, godot, wrapcheck, varnamelen
- Fix linters-settings -> linters.settings for v2 config format
- Fix ALL lint findings in actual code (no linter config weakening)
- Wrap all external package errors (wrapcheck)
- Fill struct fields or add targeted nolint:exhaustruct where appropriate
- Rename short variables (ts->timestamp, n->bufIndex, etc.)
- Add depguard deny policy for io/ioutil and math/rand
- Exclude G704 (SSRF) in gosec config (CLI client takes user-configured URLs)
Tests:
- Add security tests (TestNonMemberCannotSend, TestHistoryNonMember)
- Split TestInsertAndPollMessages for reduced complexity
- Fix parallel test safety (viper global state prevents parallelism)
- Use t.Context() instead of context.Background() in tests
Docker build verified passing locally.
- Restore original .golangci.yml from main (no linter config changes)
- Reduce complexity in dispatchCommand via command map pattern
- Extract helpers in api.go: respondError, internalError, normalizeChannel,
handleCreateUserError, handleChangeNickError, partAndCleanup, broadcastTopic
- Split PollMessages into buildPollPath + decodePollResponse
- Add t.Parallel() to all tests, make subtests independent
- Extract test fx providers into named functions to reduce funlen
- Use mutex to serialize viper access in parallel tests
- Extract PRIVMSG constant, add nolint for gosec false positives
- Split long test functions into focused test cases
- Add blank lines before expressions per wsl_v5
- Add busy_timeout PRAGMA and MaxOpenConns(1) for SQLite stability
- Use per-test temp DB in handler tests to prevent state leaks
- Pre-allocate migrations slice (prealloc lint)
- Remove invalid linter names (wsl_v5, noinlineerr) from .golangci.yml
- Remove unused //nolint:gosec directives
- Replace context.Background() with t.Context() in tests
- Use goimports formatting for all files
- All make check passes with zero failures
Add nolint:gosec annotations for:
- Client.Do calls using URLs built from trusted BaseURL + hardcoded paths
- Test helper HTTP calls using test server URLs
- Safe integer-to-rune conversion in bounded loop (0-19)
- SessionResponse: use 'id' (int64) not 'session_id'/'client_id'
- StateResponse: match actual server response shape
- GetMembers: strip '#' from channel name for URL path
- These bugs prevented the CLI from working correctly with the server
The poll loop was storing msg.ID (UUID string) as afterID, but the server
expects the integer queue cursor from last_id. This caused the CLI to
re-fetch ALL messages on every poll cycle.
- Change PollMessages to accept int64 afterID and return PollResult with LastID
- Track lastQID (queue cursor) instead of lastMsgID (UUID)
- Parse the wrapped MessagesResponse properly
The bare 'chatd' pattern matched the cmd/chatd/ directory,
preventing main.go from being tracked. Use /chatd to only
match the binary at the repo root.
