Dominik Schmidtandyxxhero 443cef0dc1 feat: dir= selector for path-based release filtering and traversal skip (#2609)
* feat: add dir= selector for path-based release filtering and traversal skip

Introduce a new selector key `dir=<path>` to the -l/--selector flag with two
effects: it filters releases by the directory of their defining helmfile
relative to the root helmfile (using directory-prefix matching, so
dir=apps/foo matches both apps/foo and apps/foo/sub), and it short-circuits
sub-helmfile traversal when paired with positive dir= constraints, so
non-matching branches in the helmfiles: tree are not parsed, templated, or
fetched.

The motivation is consuming aggregator-style upstreams that the operator
does not control (opendesk being the immediate example), where the user
cannot restructure the helmfile layout but still wants to act on a subset.

The dir label is auto-populated at filter time only; user-facing label
output is unchanged. The label key "dir" is reserved at state load.
Selectors that escape the root via .. or absolute paths, and the bare ".",
are rejected at parse time.

* refactor: use sync.Once for root dir resolution, extract skipForDirFilter

Add a unit test covering the per-entry skip decision: match descends,
sibling skipped, remote never short-circuited.

* feat: warn instead of fail on user-defined dir label

Hard-failing on an existing dir label is a breaking change. Log a
deprecation warning for now and turn it into an error in a later release.

* refactor: apply go fix modernizers to dir selector code

Upstream CI now fails when go fix would rewrite code. Use maps.Copy in
injectLabel and drop the explicit embedded ReleaseSetSpec in test
literals.

* fix: tighten dir selector edge cases found in review

- Always shadow a user-defined dir label at match time, also when the
  release has no auto-populated value (remote or outside-root helmfiles).
  Previously the user value was matched there despite the warning.
- Skip sibling helmfiles entries that are directories, not only files.
- Warn about a dir label declared in a release template, and warn only
  once when it comes from a bases file.
- Share the root-relative path and at-or-below checks between the release
  filter and the traversal skip; a directory whose name merely starts with
  two dots is no longer treated as escaping the root.
- Log when the root directory cannot be resolved.
- Tests: require for setup steps, t.Chdir, shared app fixture.

* docs: sync dir selector CLI help, document anchor and traversal assumption

docs/cli.md still carried the long help text. Also spell out what the dir
value is relative to, that the traversal skip assumes nested helmfiles
stay below their parent's directory, and that user-defined dir labels are
ignored for releases without an auto-populated value as well.

* fix: complete dir selector values relative to the root helmfile

Completion listed directories relative to the working directory, while
dir values are relative to the root helmfile directory. Resolve the root
from -f or HELMFILE_FILE_PATH with the same logic the app uses, and offer
nothing for values the selector would reject (absolute paths, paths that
escape the root) or for a remote root helmfile.

* refactor(state): flatten nested conditionals in label filter parsing and matching

- LabelFilter.Match: extract labelMatches helper; positive/negative loops
  become single-level guards. Also removes the pre-existing empty
  then-branch (if !ok {} else if) in the negative-label loop and the
  redundant len()>0 guards around the loops
- positiveLabelsCompatibleWith: extract positiveLabelPairCompatible so the
  double loop holds one guard instead of a nested if chain
- ParseLabels: extract parseOneLabel (separator detection, dir= value
  validation, split) so the three-level regex/dir/error nesting becomes
  flat; drop the vestigial trailing 'var err error' return

No behavior change; state/app/cmd tests incl. -race and golangci-lint pass.

* feat: support comma escape for values overwrites

Signed-off-by: zhengbayi <zhengbaiyi@sensetime.com>

* fix: harden state-values-set parsing and support \, in state-values-set-string

- Return a descriptive error instead of panicking when a --state-values-set
  assignment is missing '=', has an empty key, or ends with a trailing comma
- Support escaped commas in --state-values-set-string and preserve other
  backslashes (including trailing ones), aligning it with --state-values-set
  and Helm's --set/--set-string; quoted values keep working
- Allow empty values in --state-values-set-string for parity with
  --state-values-set
- Restructure parsing into guard-clause helpers with single-level
  conditionals; parse assignments via strings.Cut
- Extend table-driven tests: error cases, --state-values-set-string
  coverage, combined flags, and unit tests for the split/unescape helpers

yxxhero 16259008d5 feat: opt-in OpenTelemetry tracing and metrics (experimental) (#2769)
* feat(telemetry): add opt-in OpenTelemetry tracing (PR 1: lifecycle + root span)

Implements the first increment of docs/proposals/otel-tracing.md (#2767):

- pkg/telemetry: SDK setup from standard OTEL_* env vars (autoexport for
  exporter selection, env-driven sampler/propagators, OTEL_SDK_DISABLED),
  command-span lifecycle, no-op-by-default accessors
- --otel-tracing flag / HELMFILE_OTEL_TRACING env switch
- root span "helmfile <command>" with file/environment/selectors/exit_code
  attributes; TRACEPARENT-based remote-parent extraction for CI correlation
- shutdown flush on both normal-exit and signal paths (nil-safe, 5s bound)
- app.New derives its context from telemetry.CommandContext()
  (Background-identical when tracing is disabled)
- docs: otel.md user guide, experimental-features entry, design proposal
- tests: hermetic unit tests, app context-contract pinning, flag registration

Telemetry problems never fail a run: exporter misconfiguration and export
errors degrade to disabled with a warning. When disabled, behavior and
performance are identical to before (no-op tracer, no goroutines, no
network).

* feat(telemetry): trace every external process + trace-context bridges (PR 2)

Implements the second increment of docs/proposals/otel-tracing.md (#2767):

- pkg/helmexec/span.go: one span per external process started by helmfile
  (helm invocations, hooks, plugin execs) at the ShellRunner choke point —
  helm.exec (with helm.subcommand) vs os.exec, with redacted exec.args,
  exec.exit_code, and error status on failure
- pkg/helmexec/redact.go: shared argument redaction with two profiles;
  legacy is byte-identical to the historical exit-error behavior (existing
  goldens unchanged), strict (spans) additionally covers --set=k=v and
  credential flags; exit_error.go now uses the shared helper
- orphan-trace bridges with bit-identical cancellation semantics
  (context.WithoutCancel of the command context): both kubedog call sites
  (state.go) and hook execution (event.Bus gains an optional Ctx consumed
  by its default runner; state.go sets it, nil falls back to TODO as before)
- OTLP end-to-end test (in-process httptest receiver, no external
  collector): span export, error status/exit code, redaction, and
  parent-linkage to the command span
- docs/otel.md updated to the now-traced surface

Verified end-to-end with the console exporter: helmfile template on a
local chart yields the command span plus helm.exec spans for helm
version/dependency/template, all nested under it.

* feat(telemetry): state-loading and hook spans (PR 3a)

Implements the third increment of docs/proposals/otel-tracing.md (#2767):

- helmfile.discover_states around findDesiredStateFiles and helmfile.load
  around loadDesiredStateFromYamlWithBaseDir; both cover all callers
  (incl. nested helmfiles) with no signature changes
- helmfile.render / helmfile.parse children per document part, parented
  through a traceCtx field on the unexported desiredStateLoader struct
  (set once at its single construction site)
- helmfile.hook span per hook execution: Trigger's per-hook body extracted
  into runHook (readability win on its own), the hook's subprocess span
  nests under it via a per-hook ctx-swapped ShellRunner clone
  (cancellation unchanged — Bus.Ctx never carries cancellation by contract)
- pkg/telemetry/otlptest: shared in-process OTLP/HTTP receiver harness,
  now used by helmexec, event, and app span tests
- golden span-tree test at the app layer (root -> discover -> load ->
  render/parse, via the exectest fake helm) and a hook-span nesting test
- nil-ctx guard for App literals built directly by tests (App.spanParentCtx)

Verified end-to-end with the console exporter: a template run over a
gotmpl state file with a prepare hook yields the full tree with the hook's
os.exec nested under helmfile.hook.

* feat(telemetry): per-release spans nested under the load span (PR 3b)

Implements the per-release increment of docs/proposals/otel-tracing.md
(#2767) — spans nest command -> load -> release -> helm exec:

- helmexec.HelmContext gains an optional Ctx carrying the per-release span
  context; the execer's new execWithContext funnel consumes it via a
  per-call runner clone (runnerWithCtx) so the shared, cached execer is
  never mutated across concurrent workers. The seven Interface methods
  that take a HelmContext (Sync/Diff/ReleaseStatus/List/DecryptSecret/
  Delete/Test) route through it; nil Ctx behaves exactly as before.
  exec() lost its always-nil override parameter on the way (unparam).
- pkg/state/span.go: SetTraceContext + startReleaseSpan/endReleaseSpan
  helpers (release/namespace/chart/labels attributes, sorted for stable
  output); a typed-nil guard (releaseErrAsError) avoids the classic
  nil-pointer-in-interface trap on *ReleaseError.
- release spans in the worker loops: SyncReleases, DiffReleases,
  DeleteReleasesForSync, PrepareCharts, and iterateOnReleases (status/
  delete/test via a new verb parameter); their HelmContext is stamped with
  the release span context where one is built.
- pkg/app sets st.SetTraceContext(loadCtx) right after loading a state
  file, rooting all per-release spans under helmfile.load.
- bridged one more detached tracking call found on the way
  (trackReleaseIfEnabled's context.Background in the sync worker).
- golden test: release span present, nested under load, correct
  attributes; unit test for the runnerWithCtx clone semantics.

Verified with the console exporter: helmfile template yields
release.prepare(demo) under load with full attributes.

* feat(telemetry): nest status/delete/test execs under their release spans

Completes the per-release exec nesting for the iterateOnReleases-based
loops (docs/proposals/otel-tracing.md §4.4 phase 2): the do closures now
receive the release span context and stamp it into their HelmContext, so
helm status/delete/test subprocess spans nest under
helmfile.release.<verb> like sync/diff already did.

- scatterGatherReleases/iterateOnReleases/doWithReleaseSpan: do gains a
  context parameter (the release span context)
- ReleaseStatuses/DeleteReleases/TestReleases closures stamp
  HelmContext.Ctx from it
- integration test with a real execer (version-probe shim binary): the
  release's status subprocess nests under helmfile.release.status, same
  trace, with helm.subcommand=status

This also makes the otel.md claim ("upgrade, diff, delete, status, test
nested under the release span") fully accurate.

* feat(telemetry): OTel metrics — helm exec duration and release results (PR 4)

Implements the metrics increment of docs/proposals/otel-tracing.md
(#2767) on the same provider, switch, and resource as traces:

- pkg/telemetry/metrics.go: helmfile.helm.exec.duration histogram
  (subcommand, success) and helmfile.release.count counter (verb,
  result). Instruments come from the otel global meter, so recording at
  call sites is branch-free no-op when telemetry is disabled.
- Setup builds the resource once and installs both providers; reader
  selection delegates to autoexport (OTEL_METRICS_EXPORTER: otlp |
  console | prometheus | none), the OTLP reader's interval honors
  OTEL_METRIC_EXPORT_INTERVAL (read by the SDK). Shutdown flushes both
  providers (errors.Join). StartCommandSpan now carries the meter
  provider across state transitions (fixes a nil-shutdown panic).
- helmexec: finishExecSpan records exec duration for helm binaries;
  state: endReleaseSpan counts release outcomes for sync/diff/delete/
  status/test/prepare (diff counted as success when no hard error).
- otlptest: recorder routes by OTLP path (/v1/traces vs /v1/metrics)
  and decodes metrics; new FindMetric helper.
- tests: metrics recorded as no-op when disabled, provider enabled with
  the none exporter, degradation on an invalid metrics exporter, and an
  integration assertion (status exec duration datapoint + one successful
  release.count) in the shim-based state test.

Verified with the console exporter: helmfile template emits
helmfile.helm.exec.duration per subcommand (version/dependency/
template) and helmfile.release.count{verb=prepare,result=success}=1.

* fix(telemetry): address review — redaction gaps, kubedog valve, phantom metrics

Addresses all Copilot review comments on #2769:

Security (span payloads):
- exec.args: positional arguments are additionally passed through
  helmexec.RedactedURL, so credentials embedded in chart/repository URLs
  (AddRepo, RegistryLogin, OCI refs) are masked exactly like log output
- release spans sanitize helmfile.chart the same way
- error statuses no longer embed raw errors (which contain rendered
  commands, arguments, and subprocess output): the command span, release
  spans, hook spans, and exec spans now use generic descriptions; the
  concrete exit code remains an attribute, and RecordError on the root
  span is dropped

Correctness:
- kubedog safety valve restored: execWithContext now attaches the
  per-release span into the runner's own context instead of replacing it,
  so trackHandle.Cancel() can interrupt a wedged helm again and app
  cancellation semantics stay exactly as before the PR
- diff release spans/metrics: real failures are recorded (exit code 2
  "changes detected" still counts as success); previously every diff was
  exported as successful
- skipped releases no longer emit phantom spans and inflate
  helmfile.release.count: iterateOnReleases callers pass a skip predicate
  (skipUndesired for status/test; delete deletes undesired releases and
  passes nil)
- Setup shuts down the already-constructed tracer provider (bounded) when
  the metrics provider fails, instead of abandoning its batch goroutine

Tests: URL redaction cases (masked/untouched), spanAttachedContext
preserves the runner cancellation chain while attaching the caller's
span, skipUndesired, and a failing-hook span asserting the generic
message.

* fix: lint — restore nolint placement and avoid nil context literal

- the skipUndesired insertion had displaced the // nolint: unparam
  directive off iterateOnReleases (helm param is intentionally unused
  there); also fixes a skipDesired/skipUndesired comment typo
- use a typed nil in TestSpanAttachedContext (staticcheck SA1012)

* fix(telemetry): address review round 2 — remote-ref redaction, wrapper helm binaries, hook release attribution

Addresses all 6 new review comments on #2769:

Security (remote references):
- new helmexec.RedactedRef sanitizes go-getter style references for
  telemetry: forced-form prefixes (git::, s3::) preserved, whole URL
  userinfo masked (usernames carry tokens too), credential-bearing query
  parameters masked using pkg/remote's heuristic (token/password/secret/
  key/signature). Applied to helmfile.file (command span), helmfile.path
  (discover_states), helmfile.chart (release spans), and exec.args —
  log-time RedactedURL is untouched so log output is unchanged

Correctness:
- wrapper helm binaries (--helm-binary custom names) are now classified
  as helm operations by an explicit context marker stamped in the execer
  funnel, instead of the executable-basename heuristic; the same
  classification gates helmfile.helm.exec.duration, so the metric no
  longer misses wrapper invocations (classifyExec)
- release-scoped hooks (presync/postsync/preuninstall/postuninstall/
  cleanup in the sync/delete/diff workers) now attach their helmfile.hook
  spans to the active helmfile.release.* span via a variadic parent on
  the trigger functions; global hooks keep the command context and all
  29 existing call sites compile unchanged; hook cancellation stays
  detached (WithoutCancel) as before
- signal-terminated runs (Shutdown with exitCode 130/143 and nil error)
  now mark the command span with error status, consistent with their
  nonzero exit code

Tests: RedactedRef table (forced forms, userinfo, s3/token query params,
untouched cases), classifyExec marker case, hookTraceContext parent
attribution + non-cancellability + fallback.

* fix(telemetry): address review round 3 — redaction corner cases, value runners

Addresses 5 of the 6 new review comments on #2769 (the sixth — an
unused strings import in exit_error.go — is a false positive: Indent
still uses strings.Split/Builder and the package compiles):

- RedactArgs read the previous token from the progressively redacted
  output, so {--set, --set-string, secret} leaked the secret
  (the masked value hid the following flag). Read the previous token
  from the original input, restoring the legacy contract for adjacent
  secret flags
- RedactedRef fails closed for malformed references: URL-like refs with
  invalid percent escapes export a fully redacted value, and an
  unparseable query is dropped entirely instead of exported verbatim
- ShellRunner has value receivers, so a ShellRunner VALUE satisfies the
  Runner API; the helm marker stamping and the per-release span
  attachment now handle both value and pointer forms (matching
  WithContext), so value-runner callers keep release nesting and the
  helm.exec classification/metric

Regression tests: adjacent secret flags (legacy + strict), malformed
URL-like ref, malformed query, value-runner marker + span attachment.

* fix(telemetry): stamp the helm marker on the stdin funnel too

execStdIn (registry login, repo add) called the runner directly, so
wrapper --helm-binary names were misclassified as os.exec and omitted
from helmfile.helm.exec.duration on that path. The marking now goes
through a shared markHelmRunner helper (value and pointer ShellRunner
forms) used by both execution funnels.

* fix(telemetry): redact helm's --kube-token in strict profile

Helm's global --kube-token carries a bearer token; both the
two-argument and inline forms are now masked in span exec.args
(legacy exit-error output is untouched, matching its historical
behavior).

* fix(telemetry): OTel metrics best-practice alignment

- helmfile.helm.exec.duration now declares explicit bucket boundaries
  tuned for seconds-scale helm invocations (5ms…600s); the SDK defaults
  are millisecond-oriented and lumped every sub-5s invocation — the
  common case — into the first bucket, defeating the histogram
- instruments are re-created under the installed provider with the
  instrumentation scope version stamped (Setup-time, race-free)
- helmfile.release.count declares the {release} curly-annotation unit
  per the metrics naming conventions

Tested end-to-end via the OTLP integration test: exported bounds are
the tuned set, units are asserted, and the scope carries the version.

Signed-off-by: yxxhero <aiopsclub@163.com>

* feat(telemetry): per-release duration metrics behind an opt-in switch

New helmfile.release.duration histogram (seconds, same tuned buckets)
with bounded dimensions by default (verb, result). Setting
HELMFILE_OTEL_METRICS_PER_RELEASE=true adds helmfile.release and
helmfile.namespace, answering "which release is slow" from dashboards:

- well-suited to bounded CI runs; long-lived centralized collection
  needs a backend capacity/TTL story (documented in docs/otel.md)
- per-release timing remains available in traces without the flag
- env read per call (release operations are low-frequency, and tests
  toggle it)

endReleaseSpan now takes the release and the operation start time; the
five worker-loop call sites pass them (doWithReleaseSpan, SyncReleases,
DeleteReleasesForSync, PrepareCharts, DiffReleases).

Verified end-to-end with the console exporter (default dims vs
per-release) and OTLP integration tests pinning both modes.

* refactor(telemetry): maintainability pass over the runner/metric plumbing

- StartCommandSpan copies the tracingState struct instead of enumerating
  fields by hand — that pattern dropped the meter provider once already
- the two value/pointer ShellRunner switches (helm marker, span
  attachment) are unified into one withRunnerCtx helper; the duplication
  caused two review rounds of value-form misses
- classifyExec derives the helm classification from the span name
  (helmExecSpanName constant) instead of returning a third parallel bool
- metrics: shared outcomeAttrs for the verb/result dimensions, and the
  bucket slice renamed to durationBuckets with a comment covering both
  histograms that use it

* refactor(telemetry): consolidate test env lists, trace bridges, and hook prep; sync the design doc

Maintainability:
- HermeticEnvVars is now exported from pkg/telemetry (the owner of the
  env surface) and used by both telemetry tests and otlptest — the two
  copies had already drifted once (HELMFILE_OTEL_METRICS_PER_RELEASE
  needed updating in both)
- kubedogTraceContext and hookTraceContext were the same concept written
  twice; unified into traceOnlyContext(parent...) in span.go

Readability:
- runHook's nested kubectl rewrite extracted into prepareKubectlHook
  with guard-clause structure

Accuracy (docs ↔ code, drifted over five review rounds):
- §4.4 now describes the implemented mechanism: the release span is
  INJECTED into the runner's own context (preserving the kubedog safety
  valve) rather than the runner context being replaced, and helm
  classification is marker-based for wrapper binaries
- §5 exec span rows list the actual attributes incl. URL/query masking
- §6 strict profile documents RedactedRef, --kube-token, and the
  adjacent-token guarantee

- skipUndesired moved next to doWithReleaseSpan in span.go, its only
  conceptual home (span/metric suppression, not run plumbing)
- accuracy: the package doc, --otel-tracing flag help,
  experimental-features entry, and CHANGELOG now all say tracing AND
  metrics and list the third instrument (helmfile.release.duration with
  the HELMFILE_OTEL_METRICS_PER_RELEASE opt-in) — these had drifted
  when the metric was added; the PR description's metric table is
  updated to match as well

* refactor(telemetry): flatten Setup, name the prefix bound, dedupe test fake; fix instrument-count drift

Readability/maintainability:
- Setup drops from 56 to 39 lines: provider construction (including the
  shutdown-tracer-on-meter-failure recovery) moves to newProviders in
  exporter.go next to the constructors it composes
- refredact's magic 16 becomes maxForcedFormPrefix with a comment
- span_test's hand-rolled fakeRunner removed in favor of the existing
  mockRunner (same package)

Accuracy:
- "Two instruments" wording survived in docs/otel.md and the design
  proposal §7 after helmfile.release.duration was added; both now say
  three and mention the per-release opt-in

No behavior change; full -race suite green (except the pre-existing

- the span plumbing helpers (markHelmExec, withRunnerCtx,
  markHelmRunner, spanAttachedContext) move from exec.go to span.go,
  next to the marker type and classifiers they serve — exec.go keeps
  only the funnel call sites
- otlptest.SpanNames was never used outside the package; unexported
- isHelmBinary's comment now states it is the FALLBACK classifier
  (funnel invocations are marker-classified), replacing the outdated
  "cosmetic distinction" framing from before the marker existed
- docs/otel.md: release-scoped hooks nest under their release span
  (added in review round 2, never documented)

* feat: allow helmfile to continue on failed releases

Co-authored-by: Peter Honeder <peter.honeder@unwired.at>
Signed-off-by: Niklas Ott <niklas.ott@unwired.at>

* fix: skip failed-prep releases, complete flag wiring, add tests and docs (#64)

Review follow-ups for --allow-failed-releases (#2616):

- Track per-release chart preparation failures in PrepareCharts (returned
  as a map keyed by release) and remove those releases from the state in
  Run.WithPreparedCharts when --allow-failed-releases is set, so a failed
  release is never executed against its original, un-prepared chart
  reference (which could either fail again with a duplicate error or, for
  charts requiring chartify, bypass patches/dependency modifications and
  produce an unintended result). All failures are still reported at the
  end via the aggregated MultiError.
- Complete the release identity on error results from
  prepareChartForRelease so failures are attributed to the correct
  release.
- With --allow-failed-releases, continue building dependencies of the
  remaining charts when 'helm dep build' fails for one release, and skip
  the affected releases during execution.
- Wire --allow-failed-releases into 'helmfile unittest' and 'helmfile

yxxhero 7bebfab71a feat: add --repo-retries for helm repo and registry login commands (#2683)
* feat: add --repo-retries for retrying helm repo and registry login commands

Add a configurable retry mechanism for chart repository operations to
handle unstable networks (corporate proxies, slow internal registries).

Closes #1894

- New --repo-retries N flag and HELMFILE_REPO_RETRIES env var (default 0
  = opt-in, backward compatible)
- Retry applies to helm repo add, helm repo update (incl. ACR), and
  helm registry login with exponential backoff (1s, 2s, 4s, ..., capped 30s)
- Single retryRepoOp helper; per-attempt args/buffer are local to avoid
  state leaking across retries
- Tests cover succeed-after-retry, exhausted-retries, disabled-by-default,
  and regression guards for password-buffer and args-accumulation

Signed-off-by: yxxhero <aiopsclub@163.com>

* fix: address PR review (overflow guard, cancellable sleep, flag-override, docs)

Address Copilot review feedback on #2683:

- Cap backoff shift exponent at 5 to prevent time.Duration overflow on
  large --repo-retries values
- Make retry sleep context-aware (sleepCtx) so Ctrl+C aborts the retry
  loop promptly via the ShellRunner context
- Log a concise exit status instead of the verbose ExitError dump, and
  clarify the retry-counter wording ('retry N/M')
- Use -1 sentinel as the CLI default so --repo-retries=0 can explicitly
  disable retries even when HELMFILE_REPO_RETRIES is set
- Align help text and docs: retry applies 'on failure' (not just
  transient errors), document the 0-disables behavior
- Add tests for overflow guard, cancellable sleep, and flag-zero-disables

* fix: abort retries on canceled context, hide sentinel default, align comment

Address follow-up Copilot review on #2683:

- Fix tight-loop bug: sleepCtx now returns whether it completed vs was
  interrupted by context cancellation, and retryRepoOp aborts the retry
  loop on interruption so Ctrl+C no longer spins into rapid helm calls
- Hide the -1 sentinel from --help by overriding the displayed default
  to 0 (pflag DefValue), matching the documented default while keeping
  the flag-override semantics
- Correct HelmExecOptions.RepoRetry comment: 'on failure' not 'transient
  network errors', matching the actual retry behavior
- Add Test_Retry_AbortsOnCanceledContext covering the no-tight-loop path

* fix: copy args per retry in RegistryLogin, make cancel test deterministic

Address follow-up Copilot review on #2683:

- RegistryLogin: pass a per-attempt copy of args to execStdIn so its
  internal append (for helm.extra) can't alias the shared slice across
  retries
- Test_Retry_AbortsOnCanceledContext: cancel the context deterministically
  inside the op closure after the first attempt, replacing the flaky
  time.Sleep(20ms) goroutine

yxxhero e3f757d5ed feat: add --template-args flag to template/apply/sync for helm lookup() support (#2666)
* feat: add --template-args to enable helm lookup() during template/apply/sync (#1833)

Add a --template-args flag to the template, apply, and sync subcommands so
extra args (most notably --dry-run=server) can be passed to the helm template
invocation, enabling Helm's lookup() function to resolve live cluster values.

- template: --template-args reaches both chartify's pre-render helm template
  and the final helm template output (flagsForTemplate).
- apply/sync: --template-args reaches chartify's pre-render helm template.
  apply/sync already inject --dry-run=server automatically for cluster
  operations; the flag is an explicit opt-in for the template subcommand or
  for passing additional flags.
- When --dry-run is present in template args, kube-context/kubeconfig are also
  injected into chartify so lookup() can actually reach the cluster.
- Resolves the long-stale PR #1833 rebased onto current main, which already
  contains the cluster-connectivity infrastructure (issues #2271, #2309,
  #2355, #2444).
- Includes integration test (lookup.sh) covering both chartify and
  non-chartify scenarios.

* test: make lookup template nil-safe to fix integration CI

The lookup() function returns an empty map when the chart is rendered
without a cluster connection (notably the helm-diff phase of `helmfile
apply`). The original fixture chained `index` over the lookup result,
panicking with "index of untyped nil" during apply's diff rendering.

Guard every index with `default dict` so the template falls back to
"overwritten" when lookup is empty, while still resolving to the live
value ("init") when cluster access is available (--dry-run=server via
--template-args, or a real helm upgrade).

Signed-off-by: yxxhero <aiopsclub@163.com>

* feat: enable lookup() during apply/diff via --template-args in helm-diff

Thread --template-args into the helm-diff rendering path so that
`helmfile apply`/`diff --template-args="--dry-run=server"` resolves
Helm's lookup() function during the diff phase too. helm-diff supports
`--dry-run=server`, which explicitly "enables the cluster access ...
and the lookup template function".

Previously --template-args only reached chartify's pre-render (which is a
no-op for plain charts due to chartify's early-return when there is no
forceNamespace/patches/injections) and the final `helm template` of the
`template` subcommand. As a result `helmfile apply` on a lookup chart
rendered client-side during the diff phase.

Changes:
- pkg/state: add TemplateArgs to DiffOpts; append it in appendExtraDiffFlags
  (reaches every helm-diff invocation: apply, standalone diff, interactive
  sync), mirroring the existing flagsForTemplate handling.
- pkg/config + cmd: add --template-args to the diff/doctor commands and to
  DiffConfigProvider, so lookup works for `helmfile diff` as well.
- pkg/app: populate DiffOpts.TemplateArgs from apply/diff/sync-interactive.
- docs/cli.md: correct the previous overpromising wording and document diff
  support plus the nil-safe lookup guidance.
- tests: unit-test the TemplateArgs handling in appendExtraDiffFlags and
  flagsForTemplate; integration lookup.sh now exercises apply with
  --template-args="--dry-run=server".

* refactor: de-duplicate chartify template-args logic, add helmDefaults.templateArgs

Address review feedback on #2666:

1. Eliminate stale duplicated test helpers (issue_2444_test.go, issue_2355_test.go).
   Both files intentionally copied the processChartification flag-building logic
   with explicit SYNC WARNING comments, then drifted out of sync when #2666
   refactored the production code (needsKubeConnection gate, user-args merge).
   Extract the real logic into pure, unit-tested helpers
   (buildChartifyTemplateArgs, commandRequiresCluster) and delete the copies.

2. Add unit coverage for the new chartify merge path: template +
   --template-args=--dry-run=server now triggers kubeconfig/kube-context
   injection (TestTemplateArgsDryRunTriggersKubeInjection,
   TestTemplateArgsMergedBeforeInjection) — previously only covered by the
   cluster-dependent integration test.

3. Add a negative integration case (lookup.sh assert_template_fallback)
   verifying lookup() falls back to the default value WITHOUT --template-args,
   guarding against a regression that silently always connects to the cluster.

4. Add helmDefaults.templateArgs for parity with diffArgs/syncArgs, so users
   can enable lookup() support permanently instead of passing the flag on every
   invocation. CLI --template-args overrides (does not merge with) the default.
   Resolved via effectiveTemplateArgs, wired into the chartify, flagsForTemplate,
   and appendExtraDiffFlags paths.

5. Minor: capitalize --template-args help text to match surrounding flags;
   document helmDefaults.templateArgs precedence in docs/cli.md.

  buildChartifyTemplateArgs), closing the last unit-level coverage gap for
  helmDefaults.templateArgs reaching the chartify path.

yxxhero 9b943adc9e feat: add helmfile doctor command for AI-assisted diff analysis (#2660)
* feat: add `helmfile doctor` command for AI-assisted diff analysis

`helmfile doctor` runs `helmfile diff` and asks an OpenAI-compatible LLM to
summarize the changes and flag risks (data loss, security exposure, breaking
changes, downtime, performance, best-practice issues).

Key design decisions:
- When no LLM is configured, doctor is equivalent to `helmfile diff` with
  one exception: --show-secrets is always forced off (secrets never reach
  stdout, even without an LLM).
- Secrets are ALWAYS redacted via two layers: (1) ShowSecrets() forced to
  false so helm-diff emits <REDACTED> placeholders; (2) a defense-in-depth
  text redactor strips residual secret-looking content (Secret YAML blocks,
  sensitive key/value lines, base64 blobs, JWT tokens) before LLM transmission.
- LLM configuration precedence: env (HELMFILE_LLM_*) < helmfile.yaml (llm:)
  < CLI flags (--llm-*).
- Supports any OpenAI-compatible backend (OpenAI, Azure, One-API, LiteLLM,
  Ollama, etc.) with automatic response_format fallback for backends that
  don't support JSON mode.
- Prompt injection defense: release names and environment values are
  JSON-encoded before insertion into the LLM prompt.
- Exit codes: 0 (success/low-risk), 2 (high-risk gate, bypass with --force),
  1 (other errors). Helm-diff's 'detected changes' exit-2 is swallowed.

New packages:
- pkg/agent/llm: OpenAI-compatible client with JSON response parsing, mock
  client for testing, prompt builder with injection defense.
- pkg/agent/doctor: secret redactor (state machine + regex), report renderer
  (markdown + JSON), config resolver (env < yaml < flag merge).

Testing: 70+ unit tests covering redaction patterns, prompt injection,
response_format fallback, JSON parsing, yaml roundtrip, concurrency safety,
panic recovery, and error propagation. go test -race passes.

Documentation: full doctor section in docs/cli.md, llm: block reference in

* docs: fix doctor equivalence wording per PR review

Per review feedback (PR #2660): the docs claimed doctor is 'equivalent to
helmfile diff — same flags, same output, same exit codes' in the unconfigured
path, but this over-promises because:

  1. doctor --output is the report format (not helm-diff's output format)
  2. helm-diff's --output is exposed as --diff-output in doctor
  3. --show-secrets is silently ignored

Updated all three locations (cli.md, cmd/doctor.go Long + godoc, pkg/app/doctor.go
godoc) to say 'falls back to helmfile diff with --show-secrets forced off' and
explicitly note the --output / --diff-output flag difference.

Dominik Schmidt 33eadc993e feat: support HELMFILE_* env vars for more global flags (#2606)
* feat: support more HELMFILE_* env vars as flag fallbacks

Adds env-var fallbacks for global flags, mirroring the existing
HELMFILE_ENVIRONMENT / HELMFILE_KUBE_CONTEXT pattern:

* --helm-binary       -> HELMFILE_HELM_BINARY
* --kustomize-binary  -> HELMFILE_KUSTOMIZE_BINARY
* --log-level         -> HELMFILE_LOG_LEVEL
* --debug             -> HELMFILE_DEBUG       (expecting "true" lower case)
* --quiet             -> HELMFILE_QUIET       (expecting "true" lower case)
* --no-color          -> HELMFILE_NO_COLOR    (expecting "true" lower case),
                         additionally honors NO_COLOR per no-color.org
                         (any non-empty value disables color)

Flag values still take precedence; env vars are consulted only when the
flag is unset. The string-flag default values ("helm", "kustomize",
"info") move into the accessor methods so the env-var fallback can
actually trigger when no flag is passed.

* fix: make Color/NoColor/env interaction consistent

Two issues with the env-aware NoColor() introduced together with
HELMFILE_NO_COLOR / NO_COLOR support:

1. Color() consulted the raw GlobalOptions.NoColor field instead of
   NoColor(), so in a TTY with only the env set, Color() fell through
   to terminal autodetect and ValidateConfig() spuriously errored with
   "--color and --no-color cannot be specified at the same time".

2. NoColor() returned true via env even when --color was explicitly
   passed, so `helmfile --color` with NO_COLOR (or HELMFILE_NO_COLOR=true)
   in the environment hit the same ValidateConfig() error. A flag should
   always win over an env var.

Fix both by routing Color() through NoColor() and giving NoColor() an
explicit --color short-circuit. Regression tests added for both paths.
