USERHOST, VERSION, ADMIN, INFO, TIME, KILL and WALLOPS work on the
HTTP API and on the IRC listener. The USERHOST reply, the VERSION and
INFO text, KILL and WALLOPS are each one service function that both
transports call. User mode +w selects who receives WALLOPS. MODE on
your own nick queries or changes your user modes through one parser
on both transports: the whole mode string is checked before anything
is stored, and both flags are stored in one transaction. KILL closes
the victim's IRC connection after sending it KILL and ERROR. The
sessions table gains is_wallops in 001_initial.sql, as the pre-1.0
rule in REPO_POLICIES.md asks.
Model: opus-5-5
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.
