lukaszraczylo cda8b4be47 feat: anonymous usage telemetry via oss-telemetry
Send a single fire-and-forget ping at startup to help track adoption
and version spread. No persistent identifiers are collected.

main() is wrapped via runMain() so deferred Wait drains in-flight pings
before os.Exit.

Opt out via any of:
  DO_NOT_TRACK=1
  OSS_TELEMETRY_DISABLED=1
  KPORTAL_DISABLE_TELEMETRY=1

lukaszraczylo 3f11219dc1 test: drain healthcheck goroutine + lock read in HealthCallback test
CI on Linux flagged a race in TestStartWorker_HealthCallback_StatusChange:
the test read ui.updates while the healthchecker's per-port goroutine
(spawned by Register at checker.go:164) was still running and could
fire UpdateStatus through notifyStatusChange.

The earlier mutex on MockStatusUpdater protected the writes; the read
side was unprotected, and the goroutine had not finished by the time
the test started ranging over the slice on slower runners.

Fix:
  - call healthChecker.Unregister(fwd.ID()) to drain the per-port
    goroutine before reading
  - hold ui.mu around the slice read for belt-and-suspenders happens-
    before, regardless of goroutine timing

Verified locally with go test -race -count=20 on the targeted test
and -count=3 on the full forward package.

lukaszraczylo 0c11838326 refactor(cmd): extract main() into testable run() + per-mode helpers
main() body is now os.Exit(run(ctx, args, stdin, stdout, stderr))
where ctx comes from signal.NotifyContext and IO is io.Reader/Writer
instead of os.Std*. run() parses flags via a fresh flag.NewFlagSet
(no more package-level flag.* globals) and dispatches to:

  runShowVersion(stdout)
  runCheckUpdate(stdout, stderr)
  runConvert(input, output, stdout, stderr)
  runHeadless(ctx, opts)
  runVerboseTable(ctx, opts)
  runInteractive(ctx, opts)

Helpers extracted: parseFlags, resolveConfigPath, initLoggers,
configureStdlibLog, loadOrCreateConfig, buildRuntimeDeps,
makeHTTPLogSubscriber, shutdownManager. Signal-loop and fsnotify
watcher exit cleanly on ctx.Done() (previously chan-based with
unconditional os.Exit).

Behaviour preserved by smoke checks: -version, -update, generate
without --context, generate with bogus context, -check on
missing/valid config, -headless start+SIGINT shutdown.

Coverage: cmd/kportal 17.4% -> 71.3%. New run_test.go exercises
run() and every run* mode. main() and runInteractive remain at 0%
(TTY-required); not feasible without a tea.Program factory
abstraction, which would add complexity for minimal coverage gain.

lukaszraczylo b7b297c576 test: make MockStatusUpdater thread-safe for concurrent callbacks
The mock recorded calls into unprotected slices while being invoked
concurrently from the test goroutine and from the health-checker
callback registered by Manager.startWorker (and the watchdog hung
callback). go test -race -count=20 reliably tripped the race detector
on TestStartWorker_HealthCallback_StatusChange.

Wrap the slice writes in a sync.Mutex. Read-side code in tests reads
only after manager.Stop() drains the background goroutines (Stop's
wg.Wait establishes a happens-before edge), so direct reads remain
race-free.

lukaszraczylo 90ddca6709 test: cover ui handlers/views/commands/table
internal/ui: 27.9% -> 79.8%. Adds three test files (~3300 lines):
  - wizard_handlers_extended_test.go: keyboard branches not previously
    covered (ctrl+c, pgup/pgdn, search filter typing, port-checked
    failure path, alias text edit, focus toggling, error states),
    plus removeForwardsCmd / removeForwardByIDCmd against real Mutator
    + tempdir config (dedup + at-least-one-namespace validation).
  - wizard_views_test.go: every renderXxx path with a populated
    AddWizardState — context/namespace selectors, resource selection,
    port entry, http log list/detail, success, scroll indicators.
  - table_test.go: AddForward / UpdateStatus / SetError / Clear /
    FilterStrings flows.

Test-only fixups noted by agent:
  - getFilteredEntries silently skips StatusCode==0 entries (only
    completed responses are visible). Tests now seed StatusCode=200.
  - handleForwardSaved leaves step=StepConfirmation on save error
    rather than advancing to StepSuccess; assertion corrected.
  - removeForwardsCmd needs >=2 forwards in a context for dedup tests
    so removing one leaves the context non-empty (validator rejects
    empty contexts).

go test -race -count=1 ./... clean across all 14 packages.

lukaszraczylo ed80015e23 test: cover forward manager/worker/watchdog/portchecker
internal/forward: 45.9% -> 70.8%. Adds 14 critical-gap tests:
  - Manager.startWorker registration + duplicate error + healthcheck
    callback paths (status changes via MarkStarting/MarkReconnecting)
    + watchdog hung-callback (backdated heartbeat + checkWorkers).
  - stopWorker delegate + stopWorkerInternal removeFromUI=false.
  - DisableForward / EnableForward all error paths.
  - Reload diff logic: remove-stale, keep-unchanged, port conflict,
    empty new-config, currentConfig update.
  - SetMDNSPublisher trivial setter.
  - Watchdog.RegisterWorkerWithResponder alive/dead/transition cycle
    + pollHeartbeats direct + monitorLoop heartbeat ticker branch.
  - ForwardWorker.sleepWithBackoff (normal/cancelled/verbose) +
    IsAlive doneChan branch + Start terminates on cancel.
  - Manager.Start port-conflict path.
  - getProcessUsingPortUnix empty-bound and active-bound paths.

Remaining gaps (untestable without refactoring):
  - Windows-only branches (build tag prevents execution on macOS/Linux)
  - worker.run / establishForward — need a fake k8s.PortForwarder, but
    the Manager field is *k8s.PortForwarder (concrete), so a mock
    cannot be injected without source-level refactor.

lukaszraczylo fbb13aa32f test: cover converter I/O + httplog round-trip
internal/converter: 57.1% -> 98.4%. Added 18 cases covering
ConvertKFTrayToKPortal (happy path, missing input, malformed JSON,
unwritable output, multi-entry, file mode 0600), GetConversionSummary
(happy path, missing/malformed input, empty array, dedup counters),
and convertToKPortal edge cases (empty input, zero ports, empty
WorkloadType, sort order, alias preservation, tcp/udp/empty protocol
variants).

internal/httplog: 55.7% -> 95.7%. Added 17 tests using httptest for
loggingTransport.RoundTrip (GET/POST, filter-path bypass, header
redaction at the integration layer, backend-down, nil bodies, request
counter monotonicity) and direct unit tests for readBodyLimited
(empty, small, exact-at-limit, truncated, large pool-branch, zero
maxSize).

lukaszraczylo 1b2516ce82 test: cover cmd/kportal helpers + version checker HTTP paths
cmd/kportal: 0% -> 17.4% (testable surface only — main() is a
274-statement monolith with OS signals, bubbletea TUI, kubeconfig
loading, signal-loop goroutines, and config watcher all in one
function. Hitting 70% requires extracting it into run(args,w) int,
which is a non-trivial refactor — out of scope for a coverage pass.)
Tests cover: promptCreateConfig (yes/no/EOF/empty inputs via os.Pipe
stdin redirection), contains, resolveGenerateConfigPath (all 4 system
dirs + abs/rel branches), runGenerate (missing flag, -h, unknown
flag, invalid context, malformed YAML, no-TTY error path).

internal/version: 45.7% -> 97.8%. Added httptest.NewServer + custom
rewriteTransport to redirect GitHub API calls. Covered NewChecker,
fetchLatestRelease (200/403/404/429/500, malformed JSON, empty
tag_name), CheckForUpdate (newer/same/current-newer/error/cancelled),
parseVersion edge cases (empty, single digit, alpha).

lukaszraczylo f4adeedb8f feat: 'kportal generate' subcommand to bulk-add forwards from a cluster
New subcommand that connects to a chosen kube context and walks the
user through three picker steps before writing forwards to the config:

  1. Namespace multi-select (no system-namespace exclusion)
  2. Service multi-select grouped by namespace, with already-configured
     rows greyed out and locked off
  3. Starting-port input with a live preview of consecutive local-port
     assignments, skipping any port already taken by the existing config
     or another row in the batch

Multi-port services emit one forward per port. Non-TCP ports are
skipped with a one-line warning at the end (kportal forward layer is
TCP-only). --dry-run prints the planned forwards without writing.

Subcommand dispatch lives in cmd/kportal/main.go: when os.Args[1] ==
'generate', runGenerate(os.Args[2:]) is invoked before the main
flag.Parse() so the flag.NewFlagSet 'generate' parses its own
'--context', '--config', '--dry-run' flags. Invalid contexts list
the available ones for quick correction.

Tests in internal/ui/generate_test.go cover:
  - namespace toggle / toggle-all / filter
  - service multi-select with locked already-configured rows and
    non-TCP filtering
  - port-collision-aware consecutive assignment using a real Mutator
    against a tempdir config
  - reject + recover for starting-port < 1024
  - dry-run does not invoke the mutator
  - end-to-end Update() walk through the three steps
  - parse-starting-port boundary table
  - port-step view rendering
  - ServiceCandidate.Key() determinism

README updated with a 'Generate Forwards from a Cluster' section
describing the flow and the three flags.

lukaszraczylo dbc7830546 fix(ui): edit-mode wizard allows keeping the same local port
Previously, editing a forward and keeping its local port unchanged
failed the wizard's port-availability check: the in-config scan
found the forward's own entry and reported '✗ Port N already
assigned to <self.ID>'. Users had to pick a different port,
edit, then change back.

checkPortCmd now accepts an excludeID. The wizard passes
wizard.originalID when isEditing so the forward being edited is
ignored during the in-config conflict scan. The OS-level port
check is unchanged (still catches actual port collisions).

New regression test: TestCheckPortCmd_ExcludeID_AllowsKeepingOwnPort.

lukaszraczylo bfe541565b feat(ui): toggle httpLog per-forward in add/edit wizard
Adds an HTTP-log enable toggle to the wizard's confirmation step so
users can flip httpLog on a forward without editing YAML by hand.

Behaviour:
- 'h' on the confirmation step toggles HTTPLog when not focused on
  the alias text input. When focus is on alias, 'h' is treated as
  text so users can still type aliases like 'host' or 'http-proxy'.
- The confirmation summary shows '[x] enabled' or '[ ] disabled'.
- New forwards: toggle on -> &HTTPLogSpec{Enabled: true}; off -> nil.
- Edit mode: pre-populates the toggle from the existing forward and
  preserves any advanced HTTPLog fields the user had configured in
  YAML (logFile, includeHeaders, maxBodySize, filterPath) by copying
  the original spec on save. Toggling off discards the advanced
  fields (consistent with 'absent in YAML = disabled').

State changes:
- ForwardStatus gains *config.HTTPLogSpec so the wizard can see the
  full original spec on edit.
- AddWizardState gains httpLog bool + httpLogOriginal *HTTPLogSpec.

Three new tests:
- TestHandleAddWizardKeys_HToggleHTTPLog
- TestHandleAddWizardKeys_HOnAliasFocusIsTextInput
- TestEditPrefill_PreservesHTTPLog

lukaszraczylo c413b808f1 fix(config): allow @ . : / in context names
Real kubeconfig context names commonly contain characters the
validator rejected:
  - 'admin@home', 'user@cluster.example.com' (kubectl rename, EKS
    aws-iam-authenticator)
  - 'cluster.example.com', 'gke_proj_zone_cluster.prod' (FQDN, GKE)
  - 'arn:aws:eks:us-east-1:123:cluster/foo' (EKS ARN)

kubeconfig itself imposes no character restrictions, so requiring
[a-zA-Z0-9_-] only was kportal-specific over-validation that blocked
legitimate users. Widen the allowed set to add '@', '.', ':', '/'.
Names must still start and end with a letter or digit so YAML
specials and leading whitespace remain rejected.

Tests cover the new positive cases and tighten negative coverage
(starts-with-@, ends-with-/, ends-with-dot).

lukaszraczylo 0ccc855123 fix: Manager.Stop() is now idempotent
Previously a second Stop() call would panic from a double-close on
eventBus and re-stop the healthChecker/watchdog whose contexts had
already been cancelled. Wrapping the body in sync.Once makes
sequential and concurrent double-Stop safe.

TestManager_Stop_Idempotent covers both paths.

lukaszraczylo 0a8c872b01 fix(install): pin cosign cert-identity to shared-actions workflow
Releases are signed by the lukaszraczylo/shared-actions reusable
workflow, so the Sigstore certificate subject is the workflow URL
rather than this repo. The previous regex
'https://github.com/lukaszraczylo/kportal/.*' never matched, so any
user with cosign installed would see verification fail and abort
the install.

Pin cert-identity to the exact workflow URL:
  ^https://github\.com/lukaszraczylo/shared-actions/\.github/workflows/go-release\.yaml@refs/heads/main$

Override via COSIGN_CERT_IDENTITY_REGEXP for forks of the release
pipeline. Same fix applied to README's manual verification example.

Verified end-to-end against release v0.2.90:
  cosign verify-blob ... -> Verified OK

lukaszraczylo b4256dbbce fix(install): verify SHA-256 checksums + portable version parsing
P0 #8 — install.sh fetched and installed the binary with no integrity
check whatsoever, despite README claiming cosign verification. A
compromised release or registry MITM resulted in RCE on every
installer.

Now:
  - downloads checksums.txt alongside the archive (required; abort on
    missing)
  - computes local SHA-256 with shasum -a 256 (works on macOS+Linux,
    not GNU-only sha256sum)
  - aborts on mismatch with a clear error
  - if cosign is in PATH AND the sigstore bundle is present (the latter
    already published by goreleaser), verifies cert-identity. Skipped
    silently when cosign is absent so the install path still works for
    users without cosign installed.
  - SKIP_COSIGN=1 lets users opt out of cosign verification only
    (checksum verification is always enforced).
  - DRY_RUN=1 verifies + downloads but does not install, for testing.

Also replaced GNU-only `grep -oP` (silently fails on macOS BSD grep)
with portable awk for parsing kportal --version.

NOTE: the cosign cert-identity regex matches lukaszraczylo/kportal/.*
but actual releases are signed from the shared-actions reusable
workflow. Users with cosign installed will currently see a verification
failure on real releases. Either widen the regex to lukaszraczylo/.*
or change the signing identity scheme — flagging for follow-up.

README install section updated to mention the new verification.
2026-05-06 10:45:45 +01:00
lukaszraczylo 95bda3ee3b fix: redact sensitive headers in httplog + restore headless logging
P0 #1 — HTTP traffic logger captured Authorization, Cookie, Set-Cookie,
X-Api-Key, X-Auth-Token, X-Csrf-Token, Proxy-Authorization, X-Access-Token
verbatim into log entries (file 0600 + UI subscribers). Bearer tokens
and session cookies were ending up on disk whenever httpLog.includeHeaders
was enabled.

flattenHeaders now redacts:
  - the explicit list above (case-insensitive via http.CanonicalHeaderKey)
  - any header name containing 'token', 'secret', 'password', 'apikey'
Header names remain visible; values become [REDACTED].
Redaction is unconditional and on-by-default — no opt-out flag. Users
who want raw headers can use tcpdump.

P0 #6 — Headless mode without -v silently routed both structured and
stdlib logs to io.Discard. A daemon under launchd/systemd had no way to
report errors. Headless now defaults log destination to os.Stderr; -v
controls only the level (debug vs info). TUI-quiet path is preserved.

Tests in internal/httplog/redact_test.go cover all explicit names,
substring patterns, and case variants.

lukaszraczylo 4fe3f6b21f fix(ui): Esc cancels delete confirmation instead of confirming it
In the remove-wizard's confirming state, pressing Esc was reflexively
calling removeForwardsCmd — i.e. confirming deletion. The on-screen
help text said 'Esc: Cancel'. Reflexive Esc-to-cancel destroyed data.

Esc now sets confirming=false and resets the cursor; deletion
requires Enter on Yes. Non-confirming Esc behavior (exit wizard with
ClearScreen) is unchanged.

Three regression tests added in handlers_test.go.
2026-05-06 10:45:27 +01:00
lukaszraczylo 7a33e01863 fix: 4 P0 concurrency races in forward + k8s
P0 #2 — currentConfig data race
  Manager.currentConfig was written without locking in Start/Reload but
  read from the health-checker callback goroutine. All accesses now go
  through workersMu (read or write as appropriate).

P0 #3 — Reload kills health checker permanently
  Reload's zero-forward branch called m.Stop() which tore down the
  health checker, watchdog, and event bus. After that, EnableForward
  silently registered callbacks against dead components. Now the branch
  stops only the running workers; the supervisory infrastructure stays
  alive across config changes.

P0 #4 — rest.Config write-write race
  executePortForward was mutating .Dial on the cached *rest.Config
  shared by all forwards in the same kube context. Cloning the config
  with rest.CopyConfig before mutation isolates per-forward dialers.

P0 #5 — ForwardWorker.Stop() double-close panic
  close(w.stopChan) is now wrapped in sync.Once, so concurrent Stop
  calls (Manager.Stop racing stopWorkerInternal) are safe.

New tests in internal/forward/concurrency_test.go exercise each fix
under -race: 16 concurrent worker Stops, repeated sequential Stops,
empty-Reload preserves infra pointers, and concurrent currentConfig
read/write.

lukaszraczylo 614b6e6396 test: relax TestDiscovery_GetCurrentContext for empty kubeconfig
CI runners have no kubeconfig, so clientcmd's loader returns an empty
config (no error) and CurrentContext == "". The previous assertion
'NotEmpty(context)' on the success branch was incorrect — an empty
current-context is valid for an empty kubeconfig.

Mirrors the looser pattern in TestDiscovery_ListContexts.

## [Unreleased]
## [Unreleased] - 2026-05-06
### Added
- `kportal generate --context=NAME [--config=PATH] [--dry-run]` subcommand for interactive bulk-add of forwards from a cluster. Walks namespace multi-select, service multi-select, and starting-port input; assigns consecutive local ports; emits one forward per port for multi-port services. Non-TCP ports are skipped and already-configured services are greyed out.
- HTTP log toggle in the add/edit wizard. Pressing `h` on the confirmation step toggles `httpLog: true/false` for the forward being added or edited. Advanced `httpLog` configuration set in YAML (`logFile`, `includeHeaders`, `maxBodySize`, `filterPath`) is preserved across edits.
- HTTP log header redaction. When `httpLog.includeHeaders: true`, sensitive headers (`Authorization`, `Cookie`, `Set-Cookie`, `X-Api-Key`, `X-Auth-Token`, `X-Csrf-Token`, `Proxy-Authorization`, `X-Access-Token`, plus any header whose name contains `token`/`secret`/`password`/`apikey`) have their values replaced with `[REDACTED]`. The header name is preserved. Always on, no opt-out.
- `install.sh` SHA-256 checksum verification. Every install verifies the downloaded archive against the release's `checksums.txt`. If `cosign` is on `PATH`, the checksums file's keyless cosign signature is also verified against the shared-actions reusable workflow identity. Set `DRY_RUN=1` to preview, `SKIP_COSIGN=1` to bypass cosign.
### Changed
- Headless mode (`kportal -headless`) now sends both structured and stdlib logs to stderr by default instead of `io.Discard`. `-v` still controls level (debug vs info), not destination.
- Context-name validator now permits common kubeconfig identifiers containing `@`, `.`, `:`, or `/` (e.g. `admin@home`, `user@cluster.example.com`, GKE dotted names, EKS ARNs).
- Edit-mode wizard now allows keeping the same local port. The port-availability check no longer rejects a forward's own port when editing it.
### Fixed
- `Esc` in the delete-confirmation dialog now cancels instead of confirming deletion (previously a data-loss bug).
- `Manager.Stop()` is now idempotent. Sequential or concurrent double-Stop no longer panics.
- Cosign cert-identity is now pinned to the actual signing workflow (`lukaszraczylo/shared-actions/.github/workflows/go-release.yaml@refs/heads/main`); previously cosign verification always failed.
- Internal concurrency races in the forward manager (`currentConfig` access under lock, `rest.Config` copied before mutation, `ForwardWorker.Stop` wrapped in `sync.Once`, `Reload` no longer kills the health checker). No user-visible flag, but resolves panics some users hit.

### Generate Forwards from a Cluster
The `generate` subcommand discovers services in a Kubernetes context and lets you
interactively pick which ones to forward. Selected entries are appended to the
config file with consecutive local ports starting from a value you choose.
```bash
kportal generate --context=my-cluster
kportal generate --context=my-cluster --config=/path/to/.kportal.yaml
kportal generate --context=my-cluster --dry-run
```
| Flag | Description |
|------|-------------|
| `--context` | (required) Kubernetes context to scan |
| `--config` | Path to kportal config file (default: `.kportal.yaml`) |
| `--dry-run` | Print the planned forwards but do not modify the config |
The interactive flow has three steps:
1. **Namespaces** — multi-select with `space`, toggle-all with `a`, filter with `/`.
2. **Services** — same controls; rows already present in the config are locked off, and non-TCP ports are skipped (UDP is not supported by kportal's forward layer).
3. **Port assignment** — choose a starting local port (default `10000`, must be ≥ `1024`). Local ports are assigned consecutively in stable order, skipping any already in use.
Press `enter` on the final step to save (or to print and exit when `--dry-run` is set), `b` to go back, or `esc` to cancel.

- **Errors** - Show only 4xx and 5xx responses
**Toggling per-forward logging:**
In the add/edit wizard, press `h` on the confirmation step to toggle `httpLog` on or
off for the current forward. The wizard preserves any advanced `httpLog` keys
(`logFile`, `includeHeaders`, `maxBodySize`, `filterPath`) you set in YAML.
**Header redaction:**
When `httpLog.includeHeaders: true` is set, sensitive header values are
automatically replaced with `[REDACTED]`. The header name is preserved so you can
see that an `Authorization` header was present without exposing its value. Redacted
headers include `Authorization`, `Cookie`, `Set-Cookie`, `X-Api-Key`,
`X-Auth-Token`, `X-Csrf-Token`, `Proxy-Authorization`, `X-Access-Token`, and any
header whose name contains `token`, `secret`, `password`, or `apikey`. This is
always on and cannot be disabled.
