## Summary
Adds username and hostname support to sessions, enabling standard IRC hostmask format (`nick!user@host`) for WHOIS, WHO, and future `+b` ban matching.
closes https://git.eeqj.de/sneak/chat/issues/81
## Changes
### Schema (`001_initial.sql`)
- Added `username TEXT NOT NULL DEFAULT ''` and `hostname TEXT NOT NULL DEFAULT ''` columns to the `sessions` table
### Database layer (`internal/db/`)
- `CreateSession` now accepts `username` and `hostname` parameters; username defaults to nick if empty
- `RegisterUser` now accepts `username` and `hostname` parameters
- New `SessionHostInfo` type and `GetSessionHostInfo` query to retrieve username/hostname for a session
- `MemberInfo` now includes `Username` and `Hostname` fields
- `ChannelMembers` query updated to return username/hostname
- New `FormatHostmask(nick, username, hostname)` helper that produces `nick!user@host` format
- New `Hostmask()` method on `MemberInfo`
### Handler layer (`internal/handlers/`)
- Session creation (`POST /api/v1/session`) accepts optional `username` field; resolves hostname via reverse DNS of connecting client IP (respects `X-Forwarded-For` and `X-Real-IP` headers)
- Registration (`POST /api/v1/register`) accepts optional `username` field with the same hostname resolution
- Username validation regex: `^[a-zA-Z0-9_\-\[\]\\^{}|` + "\`" + `]{1,32}$`
- WHOIS (`311 RPL_WHOISUSER`) now returns the real username and hostname instead of nick/servername
- WHO (`352 RPL_WHOREPLY`) now returns the real username and hostname instead of nick/servername
- Extracted `validateHashcash` and `resolveUsername` helpers to keep functions under the linter's `funlen` limit
- Extracted `executeRegister` helper for the same reason
- Reverse DNS uses `(*net.Resolver).LookupAddr` with a 3-second timeout context
### Tests
- `TestCreateSessionWithUserHost` — verifies username/hostname are stored and retrievable
- `TestCreateSessionDefaultUsername` — verifies empty username defaults to nick
- `TestGetSessionHostInfoNotFound` — verifies error on nonexistent session
- `TestFormatHostmask` — verifies `nick!user@host` formatting
- `TestFormatHostmaskDefaults` — verifies fallback when username/hostname empty
- `TestMemberInfoHostmask` — verifies `Hostmask()` method on `MemberInfo`
- `TestChannelMembersIncludeUserHost` — verifies `ChannelMembers` returns username/hostname
- `TestRegisterUserWithUserHost` — verifies registration stores username/hostname
- `TestRegisterUserDefaultUsername` — verifies registration defaults username to nick
- `TestWhoisShowsHostInfo` — integration test verifying WHOIS returns the correct username
- `TestWhoShowsHostInfo` — integration test verifying WHO returns the correct username

`docker build .` passes cleanly (lint, format, tests, build).
- Add username and hostname columns to sessions table (001_initial.sql)
- Accept optional username field in session creation and registration
endpoints; defaults to nick if not provided
- Resolve hostname via reverse DNS of connecting client IP at session
creation time (supports X-Forwarded-For and X-Real-IP headers)
- Display real username and hostname in WHOIS (311 RPL_WHOISUSER) and
WHO (352 RPL_WHOREPLY) responses instead of nick/servername
- Add FormatHostmask helper for nick!user@host format
- Add SessionHostInfo type and GetSessionHostInfo query

- Extract validateHashcash and resolveUsername helpers to stay under
funlen limits
- Add comprehensive unit tests for all new DB functions, hostmask
formatting, and integration tests for WHOIS/WHO responses
- Update README with hostmask documentation, new API fields, and
updated schema reference
- Add ip column to sessions table (real client IP of session creator)
- Add ip and hostname columns to clients table (per-connection tracking)
- Update CreateSession, RegisterUser, LoginUser to store new fields
- Add GetClientHostInfo query method
- Update SessionHostInfo to include IP
- Extract executeCreateSession to fix funlen lint
- Add tests for session IP, client IP/hostname, login client tracking
- Update README with new field documentation
executeRegister → passes clientIP(request) as remoteIP
handleLogin → resolves hostname for the login client, passes IP + hostname to LoginUser
Tests:
TestCreateSessionStoresIP — verifies session and client both get the IP
TestGetClientHostInfoNotFound — error path for nonexistent client
TestLoginUserStoresClientIPHostname — verifies login creates client with correct IP/hostname
TestRegisterUserStoresSessionIP — verifies registered session gets IP
README: Updated identity section to document session ip field and per-client IP/hostname tracking.

## Rework Summary
Addressed sneak's feedback to add IP tracking to sessions and IP+hostname tracking to each client connection.
### Changes
**Schema (`001_initial.sql`)**:
- Added `ip TEXT NOT NULL DEFAULT ''` to `sessions` table
- Added `ip TEXT NOT NULL DEFAULT ''` and `hostname TEXT NOT NULL DEFAULT ''` to `clients` table
**DB layer**:
- `CreateSession` now accepts `remoteIP` parameter, stores it in both the session and the initial client record
- `RegisterUser` now accepts `remoteIP` parameter, same storage pattern
- `LoginUser` now accepts `remoteIP` and `hostname` parameters, stores them in the new client record
- Added `ClientHostInfo` struct and `GetClientHostInfo()` query method
- Updated `SessionHostInfo` to include `IP` field
**Handler layer**:
- `handleCreateSession` → extracted `executeCreateSession` (also fixes funlen lint), passes `clientIP(request)` as remoteIP
- `executeRegister` → passes `clientIP(request)` as remoteIP
- `handleLogin` → resolves hostname for the login client, passes IP + hostname to `LoginUser`
**Tests**:
- `TestCreateSessionStoresIP` — verifies session and client both get the IP
- `TestGetClientHostInfoNotFound` — error path for nonexistent client
- `TestLoginUserStoresClientIPHostname` — verifies login creates client with correct IP/hostname
- `TestRegisterUserStoresSessionIP` — verifies registered session gets IP
**README**: Updated identity section to document session `ip` field and per-client IP/hostname tracking.
### Verification
- `make fmt` ✅
- `make lint` ✅ (all lint issues resolved)
- `make test` ✅ (all tests pass)
- `docker build .` ✅
docker build . passes cleanly — lint, format, tests, build all green.
What's Done Well
Schema — sessions table has username, hostname, ip columns; clients table has ip, hostname columns. All correct in 001_initial.sql.
Session creation — handleCreateSession → executeCreateSession correctly extracts real client IP via clientIP() (checks X-Forwarded-For, X-Real-IP, then RemoteAddr), resolves hostname via rDNS with 3s timeout, stores both on session and initial client.
Registration — handleRegister → executeRegister follows the same pattern. Session gets IP; initial client gets IP + hostname.
Login — handleLogin correctly resolves IP + hostname for the new client connection.
WHOIS — executeWhois looks up SessionHostInfo and uses real username/hostname in 311 RPL_WHOISUSER params. Falls back to nick/servername when empty.
WHO — handleWho uses MemberInfo.Username/Hostname in 352 RPL_WHOREPLY params with correct fallback logic.
Hostmask — FormatHostmask() and MemberInfo.Hostmask() produce correct nick!user@host format.
The ChannelMembers query was correctly updated to return Username and Hostname, but the NAMES reply doesn't use them. The data is available but not exposed.
The 353 RPL_NAMREPLY body should include hostmask info (e.g. nick!user@host format, similar to IRCv3 userhost-in-names). The README's NAMES example also still shows plain nicks, consistent with the code gap.
No test exists for NAMES showing username/hostname.
Required Fix
Update both handleNames and deliverNamesNumerics to include username/hostname in the NAMES reply body (e.g. nick!user@host format with mode prefix where applicable).
Update README 353 example to reflect the new format.
FAIL — The issue explicitly names /names as a required output surface for username/hostname, and it was not implemented. Everything else is solid.
## Review: FAIL
### Build
`docker build .` passes cleanly — lint, format, tests, build all green.
### What's Done Well
1. **Schema** — `sessions` table has `username`, `hostname`, `ip` columns; `clients` table has `ip`, `hostname` columns. All correct in `001_initial.sql`.
2. **Session creation** — `handleCreateSession` → `executeCreateSession` correctly extracts real client IP via `clientIP()` (checks `X-Forwarded-For`, `X-Real-IP`, then `RemoteAddr`), resolves hostname via rDNS with 3s timeout, stores both on session and initial client.
3. **Registration** — `handleRegister` → `executeRegister` follows the same pattern. Session gets IP; initial client gets IP + hostname.
4. **Login** — `handleLogin` correctly resolves IP + hostname for the new client connection.
5. **WHOIS** — `executeWhois` looks up `SessionHostInfo` and uses real `username`/`hostname` in `311 RPL_WHOISUSER` params. Falls back to nick/servername when empty.
6. **WHO** — `handleWho` uses `MemberInfo.Username`/`Hostname` in `352 RPL_WHOREPLY` params with correct fallback logic.
7. **Hostmask** — `FormatHostmask()` and `MemberInfo.Hostmask()` produce correct `nick!user@host` format.
8. **Tests** — Good coverage: `TestCreateSessionStoresIP`, `TestLoginUserStoresClientIPHostname`, `TestRegisterUserStoresSessionIP`, `TestWhoisShowsHostInfo`, `TestWhoShowsHostInfo`, `TestSessionUsernameDefault`, `TestChannelMembersIncludeUserHost`, hostmask tests, error path tests.
9. **README** — Updated with hostmask docs, session/register API changes, WHOIS/WHO examples, schema table.
### Failing Issue
**NAMES does not show username/hostname** — [Issue #81](https://git.eeqj.de/sneak/chat/issues/81) explicitly says:
> "this needs to show in /whois and /names etc"
Neither `handleNames` (explicit `/NAMES` command, ~line 2044) nor `deliverNamesNumerics` (JOIN-triggered NAMES, ~line 1465) was updated. Both still output plain nicks only:
```go
for _, mem := range members {
nicks = append(nicks, mem.Nick)
}
```
The `ChannelMembers` query was correctly updated to return `Username` and `Hostname`, but the NAMES reply doesn't use them. The data is available but not exposed.
The `353 RPL_NAMREPLY` body should include hostmask info (e.g. `nick!user@host` format, similar to IRCv3 `userhost-in-names`). The README's NAMES example also still shows plain nicks, consistent with the code gap.
No test exists for NAMES showing username/hostname.
### Required Fix
1. Update both `handleNames` and `deliverNamesNumerics` to include username/hostname in the NAMES reply body (e.g. `nick!user@host` format with mode prefix where applicable).
2. Update README `353` example to reflect the new format.
3. Add integration test(s) verifying NAMES returns hostmask data.
### Verdict
**FAIL** — The issue explicitly names `/names` as a required output surface for username/hostname, and it was not implemented. Everything else is solid.
Fixed the NAMES handler to include hostmask data as identified in the review.
Changes
internal/handlers/api.go:
deliverNamesNumerics (JOIN-triggered NAMES): changed from mem.Nick to mem.Hostmask() so RPL_NAMREPLY body outputs nick!user@host format
handleNames (explicit /NAMES command): same change — now outputs nick!user@host in the NAMES reply body
README.md:
Updated 353 RPL_NAMREPLY example to show hostmask format instead of plain nicks
internal/handlers/api_test.go:
TestNamesShowsHostmask — integration test: creates a session with known username, issues explicit NAMES command, verifies the 353 reply body contains nick!user@host format
TestNamesOnJoinShowsHostmask — integration test: verifies that the NAMES reply delivered on JOIN (via deliverNamesNumerics) also includes hostmask data
setupChannelWithIdentMember — shared helper extracted to avoid dupl lint violation
assertNamesHostmask — assertion helper that checks 353 body for expected hostmask prefix
Verification
make fmt-check✅
make lint✅
make test✅ (all tests pass including both new NAMES hostmask tests)

## Rework Summary
Fixed the NAMES handler to include hostmask data as identified in the review.
### Changes
**`internal/handlers/api.go`**:
- `deliverNamesNumerics` (JOIN-triggered NAMES): changed from `mem.Nick` to `mem.Hostmask()` so RPL_NAMREPLY body outputs `nick!user@host` format
- `handleNames` (explicit `/NAMES` command): same change — now outputs `nick!user@host` in the NAMES reply body
**`README.md`**:
- Updated `353` RPL_NAMREPLY example to show hostmask format instead of plain nicks
**`internal/handlers/api_test.go`**:
- `TestNamesShowsHostmask` — integration test: creates a session with known username, issues explicit NAMES command, verifies the 353 reply body contains `nick!user@host` format
- `TestNamesOnJoinShowsHostmask` — integration test: verifies that the NAMES reply delivered on JOIN (via `deliverNamesNumerics`) also includes hostmask data
- `setupChannelWithIdentMember` — shared helper extracted to avoid `dupl` lint violation
- `assertNamesHostmask` — assertion helper that checks 353 body for expected hostmask prefix
### Verification
- `make fmt-check` ✅
- `make lint` ✅
- `make test` ✅ (all tests pass including both new NAMES hostmask tests)
- `docker build .` ✅
Login flow correctly stores IP/hostname on the new client without modifying the session's original values (matching the issue requirement: "reverse dns of the actual connecting client for the session creation initial client")
Tests are honest: no mocking, full integration test with real server + DB, assertions check actual hostmask format in 353 body
Minor Documentation Note
The README prose section correctly documents ip on sessions and ip/hostname on clients, but the Database Schema reference tables are missing these rows:
sessions table: ip column not in table
clients table: ip and hostname columns not in table
This is a minor inconsistency (prose is correct, table is incomplete). Not blocking.
## Review: PR #82 — Username/Hostname Support (post-rework #2)
**Verdict: PASS** ✅
### Checklist
| Requirement | Status | Notes |
|---|---|---|
| NAMES uses `nick!user@host` (JOIN-triggered `deliverNamesNumerics`) | ✅ | `mem.Hostmask()` correctly used |
| NAMES uses `nick!user@host` (explicit `handleNames`) | ✅ | Same pattern, both paths fixed |
| WHOIS (311) shows username + hostname | ✅ | `GetSessionHostInfo` lookup, falls back correctly |
| WHO (352) shows username + hostname | ✅ | Uses `mem.Username` / `mem.Hostname` from `MemberInfo` |
| Sessions table: `username`, `hostname`, `ip` | ✅ | Schema + `CreateSession` + `RegisterUser` all correct |
| Clients table: `ip`, `hostname` | ✅ | Schema + all 3 client-creation paths (session/register/login) |
| Integration tests for NAMES hostmask | ✅ | `TestNamesShowsHostmask` + `TestNamesOnJoinShowsHostmask` — meaningful assertions |
| README 353 example shows hostmask | ✅ | Updated to `nick!user@host` format |
| `docker build .` passes | ✅ | All tests pass, 63.8% handler coverage |
| REPO_POLICIES compliance | ✅ | No linter/config changes, no mocking, clean Go style |
### Code Quality Notes
- **Clean decomposition**: `clientIP()`, `resolveHostname()`, `resolveUsername()`, `validateHashcash()`, `FormatHostmask()` are all well-separated utility functions
- **`Hostmask()` method on `MemberInfo`** is the right pattern — keeps formatting logic centralized
- **DNS timeout bounded** at 3s via context — prevents session creation from hanging on slow DNS
- **Proxy header handling** correct: X-Forwarded-For → X-Real-IP → RemoteAddr
- **Login flow** correctly stores IP/hostname on the new client without modifying the session's original values (matching the issue requirement: "reverse dns of the actual connecting client for the session creation initial client")
- **Tests are honest**: no mocking, full integration test with real server + DB, assertions check actual hostmask format in 353 body
### Minor Documentation Note
The README prose section correctly documents `ip` on sessions and `ip`/`hostname` on clients, but the Database Schema reference tables are missing these rows:
- `sessions` table: `ip` column not in table
- `clients` table: `ip` and `hostname` columns not in table
This is a minor inconsistency (prose is correct, table is incomplete). Not blocking.
session gets ip+hostname and that is used for the display and /whois etc. client gets ip and hostname and that is not displayed anywhere at the moment (except when an oper does /whois of a user).

## Rework: oper-only client IP/hostname in WHOIS
Implemented per sneak's instructions — client-level IP/hostname is now only visible to **server operators** (o-line users) via WHOIS.
### Changes
**OPER command** (new):
- Added `OPER` command handler: authenticates against `NEOIRC_OPER_NAME` / `NEOIRC_OPER_PASSWORD` env vars
- On success: sets `is_oper` flag on session, returns `381 RPL_YOUREOPER`
- On failure: returns `491 ERR_NOOPERHOST`
- Added `is_oper` column to sessions table in schema
**Oper-aware WHOIS**:
- When a **server oper** does `/whois`, the response now includes `338 RPL_WHOISACTUALLY` with the target's current client IP and hostname
- Non-opers see no change — client IP/hostname remains hidden
- `313 RPL_WHOISOPERATOR` is now sent when the WHOIS target is a server oper
**LUSERS**:
- `252 RPL_LUSEROP` now reports the real oper count instead of hardcoded `0`
**README fixes**:
- Added `ip` and `is_oper` to sessions schema table
- Added `ip` and `hostname` to clients schema table
- Added OPER command documentation with C2S/S2C examples
- Added 313, 338, 381, 491 to numeric reply tables
- Updated WHOIS docs to describe oper-visible data
- Added `NEOIRC_OPER_NAME` and `NEOIRC_OPER_PASSWORD` to configuration table
**Tests** (7 new):
- `TestOperCommandSuccess` — successful OPER auth
- `TestOperCommandFailure` — wrong password → 491
- `TestOperCommandNeedMoreParams` — missing params → 461
- `TestOperWhoisShowsClientInfo` — oper sees 338 with client IP
- `TestNonOperWhoisHidesClientInfo` — non-oper does NOT see 338
- `TestWhoisShowsOperatorStatus` — 313 shown when target is oper
- `TestOperNoOlineConfigured` — OPER fails when no o-line configured
- DB tests: `TestSetAndCheckSessionOper`, `TestGetLatestClientForSession`, `TestGetOperCount`
**Code quality**:
- Refactored `executeWhois` into smaller helpers (`whoisNotFound`, `deliverWhoisUser`, `deliverWhoisOperator`) to stay under funlen limit
- `make fmt` ✅ | `docker build .` ✅ (lint + test + build all pass)
Review: PR #82 — Username/Hostname Support (post-rework #3)
Verdict: FAIL
Build
docker build . passes cleanly — lint, format, tests, build all green.
What's Done Well
OPER command — Clean implementation. Authenticates against NEOIRC_OPER_NAME / NEOIRC_OPER_PASSWORD env vars. Returns 381 RPL_YOUREOPER on success, 491 ERR_NOOPERHOST on failure (including when no o-line is configured), 461 ERR_NEEDMOREPARAMS when args are missing. Correctly sets is_oper flag on the session via SetSessionOper.
Oper-aware WHOIS — deliverWhoisActually correctly checks IsSessionOper(ctx, querierSID) (the querier, not the target) before sending 338 RPL_WHOISACTUALLY with client IP and hostname. Non-opers see nothing extra. This is the correct o-line behavior.
RPL_WHOISOPERATOR (313) — deliverWhoisOperator correctly checks if the target is an oper and sends 313 to any querier (not just opers). This matches IRC spec: anyone can see that a user is an oper via WHOIS.
Schema — is_oper INTEGER NOT NULL DEFAULT 0 added to sessions table. Clean.
DB layer — SetSessionOper, IsSessionOper, GetLatestClientForSession, GetOperCount all correct and well-tested.
LUSERS — 252 RPL_LUSEROP now shows real oper count from GetOperCount instead of hardcoded 0.
README — Comprehensive updates: OPER command section with C2S/S2C examples, 313/338/381/491 in numeric tables, NEOIRC_OPER_NAME/NEOIRC_OPER_PASSWORD in config table, is_oper in sessions schema table, ip+hostname in clients schema table, oper-visible WHOIS data documented.
Tests — 10 new tests covering all OPER paths: success, failure, missing params, no o-line configured, oper WHOIS shows 338, non-oper WHOIS hides 338, WHOIS shows 313 for oper target. Plus DB-level tests for SetAndCheckSessionOper, GetLatestClientForSession, GetOperCount. All honest — no mocking, no weakened assertions.
All previous requirements intact — WHOIS/WHO/NAMES with session hostmask still working correctly. No regressions.
REPO_POLICIES — .golangci.yml untouched, no linter config changes, no external dependency changes.
The handleOper function was inserted between the existing handleAway doc comment and the handleAway function definition:
// handleAway handles the AWAY command. An empty body// clears the away status; a non-empty body sets it.func(hdlr*Handlers)handleOper(// ← WRONG: this is handleOper, not handleAway...
Result:
handleOper (line 2798) has the wrong doc comment — it says "handles the AWAY command"
handleAway (line 2866) has no doc comment at all
sneak stated on this PR: "documentation and code being out of sync is always blocking". A function comment that describes a completely different function is exactly that.
Required Fix
Add a correct doc comment to handleOper (e.g. // handleOper handles the OPER command. Authenticates the session as a server operator (o-line) using configured credentials.)
Restore the handleAway doc comment above the actual handleAway function
Non-blocking Note
OPER password comparison uses != (line ~2834) rather than crypto/subtle.ConstantTimeCompare. This is a minor timing-attack surface. Not blocking for this PR since IRC oper auth is typically plaintext comparison and the env-var approach limits exposure, but worth hardening in a follow-up.
Verdict
FAIL — One blocking issue: misplaced function comment creates doc/code mismatch. Everything else is solid. Simple fix.

10. **REPO_POLICIES** — `.golangci.yml` untouched, no linter config changes, no external dependency changes.
### Blocking Issue
**Misplaced function comment: `handleAway` comment now decorates `handleOper`** ([`internal/handlers/api.go` line 2796](https://git.eeqj.de/sneak/chat/src/branch/feature/username-hostname-support/internal/handlers/api.go#L2796)).
The `handleOper` function was inserted between the existing `handleAway` doc comment and the `handleAway` function definition:
```go
// handleAway handles the AWAY command. An empty body
// clears the away status; a non-empty body sets it.
func (hdlr *Handlers) handleOper( // ← WRONG: this is handleOper, not handleAway
...
```
Result:
- `handleOper` (line 2798) has the **wrong** doc comment — it says "handles the AWAY command"
- `handleAway` (line 2866) has **no** doc comment at all
sneak stated on this PR: *"documentation and code being out of sync is always blocking"*. A function comment that describes a completely different function is exactly that.
### Required Fix
1. Add a correct doc comment to `handleOper` (e.g. `// handleOper handles the OPER command. Authenticates the session as a server operator (o-line) using configured credentials.`)
2. Restore the `handleAway` doc comment above the actual `handleAway` function
### Non-blocking Note
- **OPER password comparison** uses `!=` (line ~2834) rather than `crypto/subtle.ConstantTimeCompare`. This is a minor timing-attack surface. Not blocking for this PR since IRC oper auth is typically plaintext comparison and the env-var approach limits exposure, but worth hardening in a follow-up.
### Verdict
**FAIL** — One blocking issue: misplaced function comment creates doc/code mismatch. Everything else is solid. Simple fix.
Replaced incorrect // handleAway handles the AWAY command... comment above handleOper with correct // handleOper handles the OPER command for server operator authentication.
Replace plain != string comparison with crypto/subtle.ConstantTimeCompare
for both operator name and password checks in handleOper to prevent
timing-based side-channel attacks.
Closes review feedback on PR #82.
Problem: The handleOper function used plain != string comparison for operator name and password, which is vulnerable to timing-based side-channel attacks.
Fix: Replaced both comparisons with crypto/subtle.ConstantTimeCompare:
Both name and password are compared in constant time. Short-circuit on empty config is fine — it leaks no information about valid credentials (just that no o-line is configured, which is not secret).
No issues found. Clean fix for a real security concern.

### Rework #5 Verification
The only change in rework #5 (commit [`427ee1e`](https://git.eeqj.de/sneak/chat/commit/427ee1e)) is the timing-safe OPER credential comparison fix that sneak explicitly flagged:

### Code
```go
if cfgName == "" || cfgPass == "" ||
subtle.ConstantTimeCompare([]byte(operName), []byte(cfgName)) != 1 ||
subtle.ConstantTimeCompare([]byte(operPass), []byte(cfgPass)) != 1 {
```
Both name and password are compared in constant time. Short-circuit on empty config is fine — it leaks no information about valid credentials (just that no o-line is configured, which is not secret).
No issues found. Clean fix for a real security concern.
Review: PR #82 — Username/Hostname Support (post-rebase #6)
Verdict: PASS✅
This is a rebase-only review. The code previously passed review at rework #5 (commit 427ee1e). The only change here is a rebase onto main after PR #76 (README schema docs) was merged.

- Remove unnecessary 100ms startup sleeps from test server creation (saves ~8s)
- Remove -v flag from Makefile test target to reduce output noise

Changes
Makefile — removed -v flag from test target. Output now shows only package summaries instead of every individual test RUN/PAUSE/CONT/PASS line.
internal/db/auth.go — changed bcryptCost from const to var and added exported SetBcryptCost() function. Tests can now override bcrypt cost without changing production behavior (still uses bcrypt.DefaultCost in production).
internal/db/main_test.go (new) — TestMain sets bcrypt.MinCost for all DB tests.
internal/handlers/api_test.go — three fixes:
Added TestMain that sets db.SetBcryptCost(bcrypt.MinCost) — eliminates ~10s of bcrypt hashing overhead across auth tests
Removed time.Sleep(100ms) from newTestServer() — unnecessary delay after app.RequireStart() since httptest.NewServer is immediately ready

## Rework: Fix test speed and output verbosity
Addressed sneak's feedback on test performance and output size.
### Changes
**`Makefile`** — removed `-v` flag from test target. Output now shows only package summaries instead of every individual test RUN/PAUSE/CONT/PASS line.
**`internal/db/auth.go`** — changed `bcryptCost` from `const` to `var` and added exported `SetBcryptCost()` function. Tests can now override bcrypt cost without changing production behavior (still uses `bcrypt.DefaultCost` in production).
**`internal/db/main_test.go`** (new) — `TestMain` sets `bcrypt.MinCost` for all DB tests.
**`internal/handlers/api_test.go`** — three fixes:
1. Added `TestMain` that sets `db.SetBcryptCost(bcrypt.MinCost)` — eliminates ~10s of bcrypt hashing overhead across auth tests
2. Removed `time.Sleep(100ms)` from `newTestServer()` — unnecessary delay after `app.RequireStart()` since `httptest.NewServer` is immediately ready
3. Removed `time.Sleep(100ms)` from `newTestServerWithOper()` — same fix
### Performance
| Metric | Before | After |
|---|---|---|
| Handler tests | 24.4s | 13.8s |
| DB tests | 2.6s | 1.5s |
| Total `make test` wall time | 38s | 28s |
| Test output lines | ~300+ | ~15 |
### Integrity
- No test assertions weakened
- No linter config changes (`.golangci.yml` untouched)
- Production bcrypt cost unchanged (`bcrypt.DefaultCost` = 10)
- All tests still pass with same coverage
### Verification
- `make fmt` ✅
- `docker build .` ✅ (lint, tests, build all pass — 28s test step)
Commit: [`3e6dc10`](https://git.eeqj.de/sneak/chat/commit/3e6dc10)
One time.Sleep(200ms) remains in the long-poll test (~line 1490) — this is a legitimate test synchronization delay (waits for a poll goroutine to start before sending a message), not an unnecessary startup sleep. Correct to keep.

## Rework: conditional `-v` on test failure
Updated the Makefile `test` target per [sneak's comment](https://git.eeqj.de/sneak/chat/pulls/82):
```makefile
test: ensure-web-dist
go test -timeout 30s -race -cover ./... || go test -timeout 30s -race -v ./...
```
**Behavior:**
- First run: quiet (`-cover`, no `-v`)
- If tests fail: automatic rerun with `-v` for full verbose output
**Verification:**
- `make fmt` — ✅ pass
- `docker build .` — ✅ pass (lint, fmt-check, tests, build all green)
- Only the Makefile was changed (1 line diff)

NAMES does not show username/hostname — Issue #81 explicitly says:
Neither
handleNames(explicit/NAMEScommand, ~line 2044) nordeliverNamesNumerics(JOIN-triggered NAMES, ~line 1465) was updated. Both still output plain nicks only:The
ChannelMembersquery was correctly updated to returnUsernameandHostname, but the NAMES reply doesn't use them. The data is available but not exposed.The
353 RPL_NAMREPLYbody should include hostmask info (e.g.nick!user@hostformat, similar to IRCv3userhost-in-names). The README's NAMES example also still shows plain nicks, consistent with the code gap.No test exists for NAMES showing username/hostname.
Required Fix
handleNamesanddeliverNamesNumericsto include username/hostname in the NAMES reply body (e.g.nick!user@hostformat with mode prefix where applicable).353example to reflect the new format.Verdict
FAIL — The issue explicitly names
/namesas a required output surface for username/hostname, and it was not implemented. Everything else is solid.Rework Summary

The README prose section correctly documents
ipon sessions andip/hostnameon clients, but the Database Schema reference tables are missing these rows:sessionstable:ipcolumn not in tableclientstable:ipandhostnamecolumns not in tableThis is a minor inconsistency (prose is correct, table is incomplete). Not blocking.
session gets ip+hostname and that is used for the display and /whois etc. client gets ip and hostname and that is not displayed anywhere at the moment (except when an oper does /whois of a user).
oper being server o-line not channel +o
documentation and code being out of sync is always blocking.
Rework: oper-only client IP/hostname in WHOIS

Misplaced function comment:
handleAwaycomment now decorateshandleOper(internal/handlers/api.goline 2796).The
handleOperfunction was inserted between the existinghandleAwaydoc comment and thehandleAwayfunction definition:Result:
handleOper(line 2798) has the wrong doc comment — it says "handles the AWAY command"handleAway(line 2866) has no doc comment at allsneak stated on this PR: "documentation and code being out of sync is always blocking". A function comment that describes a completely different function is exactly that.
Required Fix

!=(line ~2834) rather thancrypto/subtle.ConstantTimeCompare. This is a minor timing-attack surface. Not blocking for this PR since IRC oper auth is typically plaintext comparison and the env-var approach limits exposure, but worth hardening in a follow-up.Verdict
