fix: nested helmfile values should replace arrays, not merge element-by-element (#2458)
PR #2367 introduced CLIOverrides to give --state-values-set element-by-element array merge semantics. However, nested helmfile values (helmfiles[].values:) were also routed into CLIOverrides, causing their arrays to merge instead of replace. This broke the pre-v1.3.0 behavior where passing an array via helmfiles[].values: would fully replace the child's default array. Add OverrideValuesAreCLI flag to SubhelmfileEnvironmentSpec so the loader can distinguish CLI flags from nested helmfile values. CLI values continue using CLIOverrides (element-by-element merge); nested helmfile values now use Values (Sparse merge strategy → full array replacement).

fix: helmDefaults.skipRefresh ignored in runHelmDepBuilds (#2415)
fix: helmDefaults.skipRefresh ignored in runHelmDepBuilds (#2269) `runHelmDepBuilds()` only checked the CLI flag (`opts.SkipRefresh`) when deciding whether to run `helm repo update` before building dependencies. This meant that setting `helmDefaults.skipRefresh: true` in helmfile.yaml had no effect on the repo update call inside dep builds. Add `!st.HelmDefaults.SkipRefresh` to the guard condition so that `helmDefaults.skipRefresh: true` is respected alongside the CLI flag. Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> |

fix: eliminate os.Chdir in sequential helmfiles to fix relative path resolution (#2410)
* fix: eliminate os.Chdir in sequential helmfiles to fix relative path resolution The sequential code path used within() → os.Chdir() to change the process-wide working directory when processing helmfile.d files. This broke relative environment variable paths (e.g. KUBECONFIG=kubeconfig.yaml) because they resolved from the wrong directory after chdir. Replace the chdir-based approach with the same baseDir parameter pattern used by the parallel code path, passing explicit directory context through loadDesiredStateFromYamlWithBaseDir() instead of mutating global process state. Closes #2409 Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: restore within() for single-file sequential to preserve chart path format The previous approach used baseDir for all sequential processing, which changed chart path format in output (e.g. from "../../../../charts/raw" to "test/integration/charts/raw"). This broke integration tests that compare chart paths in expected output. Now the sequential branch uses two strategies: - Single file: use os.Chdir via within() to preserve backward-compatible relative chart paths in output - Multiple files with --sequential-helmfiles: use baseDir parameter to avoid os.Chdir, fixing relative env var paths like KUBECONFIG (#2409) Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: revert e2e snapshot outputs to match within() behavior The previous commit restored within() for single-file sequential processing, which produces relative chart paths (e.g. ../../charts/raw) and filename-only FilePath. Revert the e2e snapshot expected outputs to match main branch since single-file behavior is now identical. Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: restructure integration test for multi-file sequential processing - Point -f at helmfile.d/ directly (not parent dir) so findDesiredStateFiles discovers the yaml files - Add second helmfile to trigger baseDir path (len > 1) - Inline environment config to avoid base file relative path issues - Verify both releases appear in output instead of comparing with parallel (which may differ in ordering) Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: reduce cognitive complexity and improve accuracy of sequential helmfiles Replace inline visitSubHelmfiles closure with calls to the existing processNestedHelmfiles() method, matching the parallel path. This eliminates duplicated nested logic and reduces gocognit complexity below the CI threshold of 110. Also fixes help text and docs to accurately describe that single-file processing still uses within(), and adds kubeContext verification to the integration test. Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * test: validate kubeContext resolution in sequential helmfiles integration test Restructure the integration test to replicate the exact user scenario from issue #2409: - Multiple files in helmfile.d/ using bases: with relative paths (../bases/) for environments and defaults - Environment values set kubeContext via .Environment.Values - helmDefaults.kubeContext rendered from gotmpl - Local chart references (../../../../charts/raw) from helmfile.d/ - Run diff against the minikube cluster to exercise kubeContext resolution, which would fail with "context does not exist" if os.Chdir() broke relative path resolution - Also verify template output for both releases and relative values file (values/common.yaml) resolution Fix normalizeChart() in util.go to be idempotent — skip re-prefixing when the chart path already starts with basePath. This prevents double-prefixing of local chart paths (e.g. helmfile.d/test/.../raw) when normalizeChart is called multiple times (once during chart preparation and again during diff/sync).

fix: helmBinary setting ignored in multi-document YAML files (#2414)
* fix: helmBinary setting ignored in multi-document YAML files The helmBinary setting in helmfile.yaml was being ignored when using multi-document YAML files (files with --- separators). Root Cause: When processing multi-document YAML files, the load() function splits the file into parts and processes each part separately. Each part was calling applyDefaultsAndOverrides() which would set an empty helmBinary to the default 'helm'. When merging parts, the default value from a later part would override the correct value from an earlier part. Fix: - Added a new applyDefaults parameter to ParseAndLoad() to control when defaults are applied - Modified rawLoad() to pass applyDefaults=false when processing individual parts - Added a call to ApplyDefaultsAndOverrides() after all parts are merged to apply defaults once on the final merged state - Exported ApplyDefaultsAndOverrides() method for use by the app package Fixes: #2319 Signed-off-by: yxxhero <aiopsclub@163.com> * fix: update comment per PR review Change 're-apply' to 'apply' since defaults are never applied during part processing (applyDefaults=false is passed), so this is the first and only time defaults are applied to the merged state. Signed-off-by: yxxhero <aiopsclub@163.com> * fix: clarify applyDefaults logic in test LoadFile callbacks Add explicit applyDefaults variable with comment explaining why it equals evaluateBases: base files shouldn't apply defaults, only the main file should after all parts/bases are merged.

fix: array merge regression - layer arrays now replace defaults (#2367)
* fix: array merge regression - layer arrays now replace defaults (#2353) PR #2288 introduced element-by-element array merging to fix #2281, but this caused a regression where layer/environment arrays were merged instead of replacing base arrays entirely. This fix uses automatic sparse array detection: - Arrays with nil values (from --state-values-set) merge element-by-element - Arrays without nils (from layer YAML) replace entirely This follows Helm's documented behavior where arrays replace rather than merge. Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: use separate CLIOverrides field for element-by-element array merging The previous approach using ArrayMergeStrategySparse detection didn't work for --state-values-set array[0]=value because setting index 0 produces no nils in the array. This fix adds a CLIOverrides field to Environment that keeps CLI values separate from layer values. CLI overrides are merged last using ArrayMergeStrategyMerge (always element-by-element), while layer values use the default strategy (arrays replace). This ensures: - --state-values-set array[0]=x only changes index 0, preserving other elements - Layer/environment file arrays still replace base arrays entirely - Issue #2281 fix is preserved (--state-values-set array[1].field=x works) Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: correct comment about array merge strategy in test Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: propagate Defaults in multi-part helmfiles and fix merge order - Add Defaults field merging from ctxEnv to preserve base values across helmfile parts separated by --- - Fix merge order: current part values now correctly override previous parts (was reversed, causing older values to win) - Update 147 snapshot test files for new Environment log format with CLIOverrides field This completes the fix for issue #2353 by ensuring: 1. Layer arrays replace entirely (not element-by-element merge) 2. CLI --state-values-set sparse arrays still merge element-by-element 3. Multi-part helmfiles properly inherit and override values Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: address Copilot review comments - Initialize EmptyEnvironment with empty maps to match New() constructor - Update test comment to accurately describe ArrayMergeStrategySparse Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: ensure templates access merged values via .Environment.Values This commit fixes a regression in the CLIOverrides integration where templates accessing .Environment.Values couldn't see CLI override values. Changes: - Remove CLIOverrides-into-Values merge from Merge() to keep proper layering order (Defaults → Values → CLIOverrides) in GetMergedValues() - Update NewEnvironmentTemplateData to set envCopy.Values to the merged values, ensuring templates see the same values via both .Values and .Environment.Values This ensures: - Issue #2353: Layer arrays still replace entirely (Sparse strategy) - Issue #2281: CLI sparse arrays still merge element-by-element - Templates can access CLI overrides via .Environment.Values Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * docs: improve mergeSlices documentation per Copilot review Address Copilot review comments on PR #2367: - Document empty array edge case: explicitly setting [] clears base array - Document recursive strategy propagation for nested map merging - Add comprehensive behavior description for all array merge strategies Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: use merged values when rendering environment value files Environment value files (*.yaml.gotmpl) can reference CLI values via .Values. Previously, only env.Values was passed to template rendering, which didn't include CLIOverrides.

fix: pass --kube-context to helm template when using jsonPatches (#2363)
fix: pass --kube-context to helm template when using jsonPatches (#2309) When using jsonPatches or strategicMergePatches in helmfile, the `helm template` command was not receiving the `--kube-context` flag. This caused issues when `--dry-run=server` was used (introduced in PR #2271 to support lookup() functions), because helm would connect to the wrong cluster context. Root Cause: 1. `flagsForTemplate()` did not call `appendConnectionFlags()`, unlike `flagsForUpgrade()` and `flagsForDiff()` which both include this call. 2. `processChartification()` did not include `--kube-context` when setting `chartifyOpts.TemplateArgs` for internal helm template calls. Fix: 1. Added `appendConnectionFlags()` call to `flagsForTemplate()` to ensure kube-context and other connection flags are passed to helm template. 2. Added `getKubeContext()` helper function that resolves kube-context with proper priority: release > environment > helmDefaults. 3. Modified `processChartification()` to include `--kube-context` in chartifyOpts.TemplateArgs when chartify needs to run helm template. 4. Added compatibility check for `--validate` flag to avoid Helm 4 mutual exclusion error between --validate and --dry-run (Issue #2355).

Add --sequential-helmfiles flag for optional sequential processing (#2350)
* Initial plan * Fix helmfile.d parallel processing to respect alphabetical order Changed multiple helmfile.d file processing from parallel to sequential to match the documented behavior. Files are now processed in alphabetical order as stated in the documentation, ensuring predictable deployment order. This fixes issues where deployments would break because parallel processing did not respect the intended ordering (e.g., databases before applications). - Modified visitStatesWithContext to process files sequentially - Removed unused processStateFileParallel function - Updated test snapshots to reflect deterministic ordering Co-authored-by: yxxhero <11087727+yxxhero@users.noreply.github.com> * Add --sequential-helmfiles flag for opt-in sequential processing Based on feedback, added a flag to control processing mode instead of forcing sequential behavior. Parallel processing is now the default for performance, with an opt-in --sequential-helmfiles flag for when order matters. Changes: - Added SequentialHelmfiles field to GlobalOptions and App - Added --sequential-helmfiles CLI flag - Modified visitStatesWithContext to check flag and choose parallel vs sequential - Updated documentation to clarify parallel is default, sequential is opt-in - Restored original parallel processing as default behavior This gives users control over the behavior based on their needs.

fix: resolve issues #2295, #2296, and #2297 (#2298)
* fix: resolve issues #2295, #2296, #2297 and OCI registry login This PR fixes four related bugs affecting chart preparation, caching, and OCI registry authentication. Issue #2295: OCI chart cache conflicts with parallel helmfile processes - Added filesystem-level locking using flock for cross-process sync - Implements double-check locking pattern for efficiency - Retry logic with 5-minute timeout and 3 retries - Refactored into reusable acquireChartLock() helper function - Added refresh marker coordination for cross-process cache management Issue #2296: helmDefaults.skipDeps and helmDefaults.skipRefresh ignored - Check both CLI options AND helmDefaults when deciding to skip repo sync Issue #2297: Local chart + transformers causes panic - Normalize local chart paths to absolute before calling chartify OCI Registry Login URL Fix: - Added extractRegistryHost() to extract just the registry host from URLs - Fixed SyncRepos to use extracted host for OCI registry login - e.g., "account.dkr.ecr.region.amazonaws.com/charts" -> "account.dkr.ecr.region.amazonaws.com" Test Plan: - Unit tests for issues #2295, #2296, #2297 - Unit tests for OCI registry login (extractRegistryHost, SyncRepos_OCI) - Integration tests for issues #2295 and #2297 - All existing unit tests pass (including TestLint) Fixes #2295 Fixes #2296 Fixes #2297 Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: replace 60s timeout with reader-writer locks for OCI chart caching Address PR review feedback from @champtar about the OCI chart caching mechanism. The previous implementation used a 60-second timeout which was arbitrary and caused race conditions when helm deployments took longer (e.g., deployments triggering scaling up/down). Changes: - Replace 60s refresh marker timeout with proper reader-writer locks - Use shared locks (RLock) when using cached charts (allows concurrent reads) - Use exclusive locks (Lock) when refreshing/downloading charts - Hold locks during entire helm operation lifecycle (not just during download) - Add getNamedRWMutex() for in-process RW coordination - Update PrepareCharts() to return locks map for lifecycle management - Add chartLockReleaser in run.go to release locks after helm callback - Remove unused mutexMap and getNamedMutex (replaced by RW versions) - Add comprehensive tests for shared/exclusive lock behavior This eliminates the race condition where one process could delete a cached chart while another process's helm command was still using it. Fixes review comment on PR #2298 Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: prevent deadlock when multiple releases share the same chart When multiple releases use the same OCI chart (e.g., same chart different values), workers in PrepareCharts would deadlock: 1. Worker 1 acquires lock for chart/path, downloads, adds to cache 2. Worker 2 finds chart in cache, tries to acquire lock on same path 3. Worker 2 blocks waiting for Worker 1's lock 4. Collector waits for Worker 2's result 5. Worker 1's lock held until PrepareCharts finishes -> deadlock The fix: when using the in-memory chart cache (which means another worker in the same process already downloaded the chart), don't acquire another lock. This is safe because: - The in-memory cache is only used within a single helmfile process - The tempDir cleanup is deferred until after helm callback completes - Cross-process coordination is still handled by file locks during downloads This fixes the "signal: killed" test failures in CI for: - oci_chart_pull_direct - oci_chart_pull_once - oci_chart_pull_once2 Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: resolve deadlock by releasing OCI chart locks immediately after download This commit simplifies the OCI chart locking mechanism to fix deadlock issues that occurred when multiple releases shared the same chart. Problem: When multiple releases used the same OCI chart, workers in PrepareCharts would deadlock because: 1. Worker 1 acquires lock for chart/path, downloads chart 2. Worker 2 tries to acquire lock on same path, blocks waiting 3. PrepareCharts waits for all workers to complete 4. Worker 1's lock held until PrepareCharts finishes -> deadlock Solution: Release locks immediately after chart download completes. This is safe because: - The tempDir cleanup is deferred until after helm operations complete in withPreparedCharts(), so charts won't be deleted mid-use - The in-memory chart cache prevents redundant downloads within a process - Cross-process coordination via file locks still works during download Changes: - Remove chartLock field from chartPrepareResult struct - Release locks immediately in getOCIChart() and forcedDownloadChart() - Simplify PrepareCharts() by removing lock collection and release logic - Update function signatures to return only (path, error) This also fixes the "signal: killed" test failures in CI for: - oci_chart_pull_direct - oci_chart_pull_once - oci_chart_pull_once2 Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: add double-check locking for in-memory chart cache When multiple workers concurrently process releases using the same chart, they all check the in-memory cache before acquiring locks. If none have populated the cache yet, all workers miss and try to download. Previously, even after acquiring the exclusive lock, the code would re-download the chart when needsRefresh=true (the default). This caused multiple "Pulling" messages in tests like oci_chart_pull_once. The fix adds a second in-memory cache check AFTER acquiring the lock. This implements proper double-check locking: 1. Check cache (outside lock) → miss 2. Acquire lock 3. Check cache again (inside lock) → hit if another worker populated it 4. If still miss, download and add to cache This ensures only one worker downloads the chart, while others use the cached version populated by the first worker. Changes: - Add in-memory cache double-check in getOCIChart() after acquiring lock - Add in-memory cache double-check in forcedDownloadChart() after acquiring lock This fixes the oci_chart_pull_once and oci_chart_pull_direct test failures where charts were being pulled multiple times instead of once. Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: use callback to prevent redundant chart downloads within a process When multiple workers concurrently process releases using the same chart, they need to coordinate to avoid redundant downloads. The previous fix set SkipRefresh=true for OCI charts, which prevented legitimate refresh scenarios (e.g., floating tags). This commit implements a better solution using a callback mechanism: 1. acquireChartLock() now accepts an optional skipRefreshCheck callback 2. Before deleting a cached chart for refresh, the callback is invoked 3. If the callback returns true (in-memory cache has the chart), skip refresh 4. This allows deduplication within a process while respecting cross-run refresh The flow is now: - Worker 1 downloads chart, adds to in-memory cache, releases lock - Worker 2 acquires lock, sees needsRefresh=true, but callback sees in-memory cache is populated → uses cached instead of deleting This correctly handles: - Within-process deduplication: only one download per chart - Cross-run refresh: respects --skip-refresh flag for floating tags - Immutable versions: cached and reused as expected Changes: - Add skipRefreshCheck callback parameter to acquireChartLock() - Update getOCIChart() to pass in-memory cache check callback - Update forcedDownloadChart() to pass in-memory cache check callback - Remove SkipRefresh=true workaround for OCI charts Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: address Copilot review comments on PR #2298 This commit addresses the automated review comments from GitHub Copilot: 1. pkg/state/state.go: Add nil check for logger in Release() method to prevent potential nil pointer dereference when logger is nil. 2. pkg/state/state.go: Fix misleading comment about "external callers" to accurately reflect that Logger() is used by the app package. 3. pkg/state/issue_2296_test.go: Add comment noting that boolPtr helper is already defined in skip_test.go (shared across test files). 4. test/integration/test-cases/oci-parallel-pull.sh: Replace hardcoded /tmp paths with a dedicated temp directory for test outputs. Add cleanup for the output directory in the cleanup function. 5. test/integration/test-cases/issue-2297-local-chart-transformers.sh: Add cleanup trap to remove temp directory on exit, preventing leftover files from accumulating. 6. Remove dead code: The chartLocks map in PrepareCharts was always empty since locks are released immediately after download. Removed the unused return value and corresponding handling in run.go to improve code clarity and maintainability.

🐛 Fix four critical issues: environment merging, kubeVersion detection, lookup() with kustomize, and Helm 4 color flags (#2276)
* fix: deep merge environments from multiple bases (#2273) Problem: When using multiple base helmfiles, environment values were being completely replaced instead of deep-merged due to mergo.WithOverride introduced in PR #2228. Solution: - Created mergeEnvironments() function for proper deep merging - Manually merge environment Values and Secrets slices before struct merge - Preserves all environment values from both base and current helmfile Testing: - Added TestEnvironmentMergingWithBases with two scenarios: 1. Multiple bases with overlapping environment values 2. Environment values with array merging Fixes #2273 Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: auto-detect Kubernetes version for helm-diff (#2275) Problem: When helmfile runs helm-diff without specifying kubeVersion, helm-diff falls back to v1.20.0. This causes chart compatibility checks to fail for charts requiring newer Kubernetes versions (e.g., kubeVersion: ">=1.25.0"). Root Cause: - flagsForDiff() was not passing kubeVersion to helm-diff plugin - Without --kube-version flag, helm-diff uses default v1.20.0 Solution: - Created pkg/cluster package with DetectServerVersion() function - Auto-detect cluster version using k8s.io/client-go discovery API - Pass detected version to helm-diff via --kube-version flag - Priority: helmfile.yaml kubeVersion > auto-detected version - Works with both Helm 3 and Helm 4 Implementation: - pkg/cluster/version.go: Cluster version detection - pkg/app/app.go: detectKubeVersion() helper used in diff() and apply() - pkg/state/state.go: Added DetectedKubeVersion field to DiffOpts - Integrated into flagsForDiff() with proper precedence Testing: - Unit tests for cluster version detection - Unit tests for kubeVersion precedence logic - Integration test with chart requiring Kubernetes >=1.25.0 - Tests verify upgrade scenario (critical failure case from issue) - Validated with both Helm 3 and Helm 4 Fixes #2275 Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: enable lookup() function with strategicMergePatches (#2271) Problem: When using strategicMergePatches (kustomize), Helm's lookup() function stops working. Charts like Grafana use lookup() to preserve existing resource values (e.g., PVC volumeName), which get lost when using patches. Root Cause: - Chartify runs "helm template" to render charts before applying patches - By default, "helm template" runs client-side without cluster access - The lookup() function requires cluster connectivity to query resources - Without cluster access, lookup() returns empty values Solution: - Pass --dry-run=server to helm template when using kustomize patches - This enables cluster connectivity for lookup() while keeping client-side rendering - Only applied to commands requiring cluster access (diff, apply, sync, etc.) - Offline commands (template, lint, build) remain cluster-independent Implementation: - Modified processChartification() to accept helmfileCommand parameter - Added switch-based logic to determine cluster requirement per command - Conditionally set chartifyOpts.TemplateArgs = "--dry-run=server" - Safe default: unknown commands assume cluster access Command Behavior: - helmfile diff/apply/sync: Uses --dry-run=server, lookup() works - helmfile template/lint/build: No cluster requirement, works offline - Charts without lookup(): Unaffected - Charts with lookup() + cluster: Lookup values preserved correctly Testing: - Integration test with ConfigMap using lookup() to preserve values - Verifies lookup works with strategicMergePatches - Tests both with and without cluster access - Validates offline template command still works Fixes #2271 Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: remove unnecessary error return from mergeEnvironments The mergeEnvironments function always returns nil, making the error return value unnecessary. This fixes the unparam linter warning. - Changed function signature to not return error - Updated call site to not handle error - All tests still pass Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: handle nil Environments map in mergeEnvironments Fixes panic when base helmfile has nil Environments map. Initialize the destination map if nil before merging to prevent "assignment to entry in nil map" panic. - Added nil check in mergeEnvironments to return early - Initialize layers[0].Environments before merge if nil - Fixes TestVisitDesiredStatesWithReleasesFiltered_Issue1008_MissingNonDefaultEnvInBase The panic occurred when a base helmfile didn't define any environments but a subsequent layer did. Now we properly initialize an empty map to merge into. Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * test: disable kubeVersion auto-detection in unit tests Add DisableKubeVersionAutoDetection field to App struct to prevent unit tests from connecting to real Kubernetes clusters during testing. The kubeVersion auto-detection feature (issue #2275) was causing unit tests to fail because: 1. Tests use mock helm implementations without real cluster access 2. Auto-detection was connecting to local minikube cluster (v1.34.0) 3. Test expectations didn't include --kube-version flag in diff keys Solution: - Add DisableKubeVersionAutoDetection bool field to App struct - Check this flag in detectKubeVersion() before attempting detection - Set flag to true in all pkg/app/*_test.go files This ensures unit tests remain isolated and don't depend on external cluster state while preserving auto-detection for production use. Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * chore: upgrade helm-diff plugin to v3.14.1 Update helm-diff plugin from v3.14.0 to v3.14.1 across all environments: - Dockerfiles (main, debian-stable-slim, ubuntu) - CI workflow matrix configurations - Integration test default version This ensures consistency across development, testing, and production environments. Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * test: fix table formatting and improve E2E test infrastructure This commit addresses multiple test failures and improves the testing infrastructure for better reliability and maintainability. Table Formatting Fixes: - Added trimTrailingWhitespace() helper function to remove trailing whitespace from table output in both FormatAsTable() and printDAG() - Fixes TestList and TestDAG failures caused by tabwriter padding empty columns with trailing spaces - Updated golden file for table output test to match new behavior E2E Test Infrastructure Improvements: - Implemented dynamic port allocation for Docker registry tests to prevent port conflicts (replaced hardcoded port 5000/5001) - Added getFreePort() function using kernel-allocated unused ports - Added waitForRegistry() function with proper health check polling of Docker Registry /v2/ endpoint (replaces sleep hack) - Added prepareInputFile() function to handle port substitution and path resolution when copying helmfile configs to temp directories - Extracted setupLocalDockerRegistry() helper to reduce cognitive complexity from 111 to ≤110 (gocognit threshold) - Added port normalization in test output to replace dynamic ports with $REGISTRY_PORT placeholder for deterministic comparisons Test Configuration Updates: - Updated OCI chart tests to use dynamic port allocation via $REGISTRY_PORT placeholder in helmfile configs - Converted relative chart paths to absolute paths when input files are copied to temp directories (fixes path resolution issues) - Left postrenderer paths as relative since they're resolved from working directory (works for both Helm 3 and Helm 4) Golden File Updates: - Updated all OCI-related test expected outputs to use $REGISTRY_PORT placeholder instead of hardcoded ports - Removed trailing whitespace from issue_493 test expected output - Updated postrenderer test outputs to reflect chart path normalization Test Cleanup: - Removed unused fakeInit struct and CheckHelmPlugins() call from snapshot tests (not needed for template/fetch/list commands) - Removed unused imports (app, helmexec packages) Technical Details: - Port allocation uses net.Listen with port 0 for kernel assignment - Registry health check polls with 500ms intervals and 30s timeout - Chart paths: ../../charts/* → absolute paths (input file moves to temp) - Postrenderer paths: remain relative (resolved from working directory) - OCI cache paths normalized: oci__localhost_PORT → oci__localhost_$REGISTRY_PORT All originally failing tests now pass: - TestList ✓ - TestDAG ✓ - TestHelmfileTemplateWithBuildCommand (all OCI tests) ✓ - TestFormatAsTable ✓ Fixes three test failures reported in issue. Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix(test): convert postrenderer paths to absolute for Helm 3 Helm 3 resolves postrenderer script paths relative to the helmfile location. When the input file is copied to a temp directory for port substitution, relative postrenderer paths break. Solution: - Added postrenderersDir parameter to prepareInputFile() - Convert ../../postrenderers/* to absolute paths for Helm 3 only - Use existing isHelm4() function to detect Helm version - Helm 4 extracts plugin names from paths, so works with relative This fixes the postrenderer test failure in CI where Helm 3 could not find the postrenderer script at the relative path.

Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: prevent helm-diff from normalizing server-side defaults Problem: The suppress-output-line-regex integration test was failing because helm-diff was reporting "has changed, but diff is empty after suppression" for Service resources when it should have shown ipFamilyPolicy and ipFamilies fields being removed. Root Cause: When auto-detected kubeVersion (e.g., 1.34.0) is passed to helm-diff via --kube-version flag, helm-diff normalizes server-side defaults. This makes fields like ipFamilyPolicy and ipFamilies appear unchanged, even though they don't exist in the chart template and will be removed by the upgrade. After applying suppressOutputLineRegex patterns, only label changes remained (helm.sh/chart and app.kubernetes.io/version). These were correctly suppressed, leaving an empty diff - hence the "diff is empty after suppression" message. Solution: Added a new configuration option 'disableAutoDetectedKubeVersionForDiff' to allow disabling auto-detected kubeVersion being passed to helm-diff. This prevents helm-diff from normalizing server-side defaults when needed. Default behavior: Pass auto-detected kubeVersion (fixes issue #2275, existing behavior) Opt-out behavior: Set flag to true to only use explicit kubeVersion from helmfile.yaml helmDefaults: disableAutoDetectedKubeVersionForDiff: true # false by default releases: - name: myrelease disableAutoDetectedKubeVersionForDiff: true # override per-release Implementation: - Added DisableAutoDetectedKubeVersionForDiff field to HelmSpec and ReleaseSpec - Updated flagsForDiff() to check this flag before passing kubeVersion - Default (false): pass auto-detected kubeVersion (fixes issue #2275) - Opt-out (true): only pass explicit kubeVersion from helmfile.yaml - Updated suppress-output-line-regex test to disable auto-detected kubeVersion This approach: - Maintains backward compatibility (default passes auto-detected kubeVersion) - Fixes issue #2275 for charts requiring newer Kubernetes versions - Allows users to opt-out when server-side normalization causes issues - Fixes suppress-output-line-regex test regression Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * test: update hash values in TestGenerateID after adding DisableAutoDetectedKubeVersionForDiff field The hash values in TestGenerateID needed to be updated because adding the DisableAutoDetectedKubeVersionForDiff field to ReleaseSpec changed the structure's hash representation. This is expected behavior as generateValuesID() hashes the entire ReleaseSpec structure. Updated all expected hash values to match the new values: - baseline: foo-values-66f7fd6f7b - different bytes content: foo-values-6664979cd7 - different map content: foo-values-78897dfd49 - different chart: foo-values-64b7846cb7 - different name: bar-values-576cb7ddc7 - specific ns: myns-foo-values-6c567f54c Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: address PR review comments and resolve issue #2280 This commit addresses all review comments from GitHub Copilot and resolves issue #2280 regarding --color flag conflict with Helm 4. Changes: 1. Fixed documentation in pkg/cluster/version.go - Updated function comment to reflect error return behavior - Corrected version format example and comment 2. Added complete command categorization in pkg/state/state.go - Added all helmfile commands to cluster access switch statement - Properly categorized 15+ commands based on cluster requirements - Added clarifying comments for command groups 3. Resolved issue #2280: --color flag conflict with Helm 4 - In Helm 4, --color expects a value (never/auto/always) - Converts --color to --color=always for Helm 4 - Converts --no-color to --color=never for Helm 4 - Prevents Helm from consuming next argument as color value - Added comprehensive unit tests - Added integration test (Helm 4 only) Issue #2280 Details: When running helmfile diff with --color and --context flags on Helm 4, the --color flag would consume --context as its value, resulting in: "invalid color mode '--context': must be one of: never, auto, always" The fix detects Helm 4 and converts boolean color flags to the format Helm 4 expects, preventing the argument consumption issue. Fixes #2280 Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: correct kubeVersion precedence comment in test The comment incorrectly stated that state.KubeVersion takes precedence over paramKubeVersion, but the actual implementation (getKubeVersion in state.go:3354-3364) shows the correct order is: 1. paramKubeVersion (auto-detected from cluster) 2. release.KubeVersion (per-release override) 3. state.KubeVersion (helmfile.yaml global setting) Updated the comment to match the implementation and the test cases. Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * fix: resolve Helm 4 --color flag conflict (issue #2280) This commit resolves issue #2280 where the --color flag causes Helm 4 to consume the next argument, resulting in errors like: "invalid color mode '--context': must be one of: never, auto, always" Root Cause: In Helm 4, the --color flag is parsed by the Helm binary before being passed to plugins like helm-diff. This causes Helm to interpret the next argument (e.g., --context) as the value for --color. Solution: Remove --color and --no-color flags from helm-diff commands when using Helm 4, and instead use the HELM_DIFF_COLOR environment variable. The helm-diff plugin supports HELM_DIFF_COLOR=[true|false] as an alternative to the --color/--no-color flags. Changes: 1. Added filterColorFlagsForHelm4() function in pkg/helmexec/exec.go - Removes --color and --no-color flags from flags slice - Sets HELM_DIFF_COLOR=true for --color - Sets HELM_DIFF_COLOR=false for --no-color 2. Modified DiffRelease() to call filterColorFlagsForHelm4() on Helm 4 3. Added comprehensive unit tests in pkg/helmexec/exec_test.go - Test_DiffRelease_ColorFlagHelm4: Verifies flags are filtered - Test_FilterColorFlagsForHelm4: Tests all flag combinations 4. Added integration test in test/integration/test-cases/issue-2280.sh - Tests the exact scenario from issue #2280 - Verifies --color and --context flags work together - Helm 4 only test (skipped on Helm 3) Fixes #2280 Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * refactor: apply Copilot code review nitpicks This commit addresses minor code quality improvements suggested by GitHub Copilot's automated review.

These are non-functional improvements that enhance code quality, performance, security, and test reliability. Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * docs: improve code comments based on Copilot feedback This commit addresses documentation nitpicks from GitHub Copilot's automated review to improve code clarity and maintainability. Changes: 1. pkg/app/app.go - Clarify detectKubeVersion() return conditions - Updated comment to explicitly list all three cases when empty string is returned: kubeVersion already set, auto-detection disabled, or detection fails - Improves function documentation clarity 2. test/e2e/template/helmfile/snapshot_test.go - Added reference to retry logic in getFreePort() comment - Points callers to setupLocalDockerRegistry() for proper race condition handling example - Better guidance for future code maintainers 3. pkg/state/state.go - Explain patches check rationale - Added comment explaining why --dry-run=server is only enabled when patches are used - Clarifies that this is a conservative approach to minimize unnecessary cluster connections - Documents primary use case (Grafana chart with PVC preservation) All changes are documentation-only with no functional impact. All tests passing. Signed-off-by: Aditya Menon <amenon@canarytechnologies.com> * refactor: enable lookup() for all cluster commands and add defensive check This commit addresses two Copilot review suggestions to improve code robustness and functionality. Changes: 1. pkg/state/state.go - Remove patches requirement for lookup() - Previously only enabled --dry-run=server when patches were present - Now enables it for ALL cluster-requiring commands - Rationale: lookup() function can be used without patches - Improves compatibility with charts using lookup() standalone - Trade-off: Slightly more cluster connections vs broader support 2. pkg/helmexec/exec.go - Add defensive check for HELM_DIFF_COLOR - Only set environment variable if not already present - Makes code more defensive for future implementation changes - Note: Changes behavior from "last wins" to "first wins" - In practice, env map is freshly created so check is precautionary 3. pkg/helmexec/exec_test.go - Update test expectations - Changed test case to reflect "first wins" behavior - Updated test name and comment for clarity Breaking behavior change: - When both --color and --no-color are present, the FIRST flag now wins instead of the LAST flag - This deviates from standard CLI conventions where later flags override earlier ones - However, this is unlikely to affect real usage as users rarely specify conflicting flags All tests passing.

perf(app): Parallelize helmfile.d rendering and eliminate chdir race conditions (#2261)
* perf(app): parallelize helmfile.d rendering and eliminate chdir race conditions This change significantly improves performance when processing multiple helmfile.d state files by implementing parallel processing and eliminating thread-unsafe chdir usage. Changes: - Implement parallel processing for multiple helmfile.d files using goroutines - Replace process-wide chdir with baseDir parameter pattern to eliminate race conditions - Add thread-safe repository synchronization with mutex-protected map - Track matching releases across parallel goroutines using channels - Extract helper functions (processStateFileParallel, processNestedHelmfiles) to reduce cognitive complexity - Change Context to use pointer receiver to prevent mutex copy issues - Ensure deterministic output order by sorting releases before output - Make test infrastructure thread-safe with mutex-protected state Performance improvements: - Each helmfile.d file is processed in its own goroutine (load + template + converge) - Repository deduplication prevents duplicate additions during parallel execution - No mutex contention on file I/O operations (only on repo sync) Technical details: - Added baseDir field to desiredStateLoader for path resolution without chdir - Created loadDesiredStateFromYamlWithBaseDir method for parallel-safe loading - Use matchChan to collect release matching results from parallel goroutines - Context.SyncReposOnce now uses mutex to prevent TOCTOU race conditions - Run struct uses *Context pointer to share state across goroutines - TestFs and test loggers made thread-safe with sync.Mutex - Added SyncWriter utility for concurrent test output Helm dependency command fixes: - Filter unsupported flags from helm dependency commands (build, update) - Use reflection on helm's action.Dependency and cli.EnvSettings structs to dynamically determine supported flags - Prevents template-specific flags like --dry-run from being passed to dependency commands - Maintains support for global flags (--debug, --kube-*, etc.) and dependency-specific flags (--verify, --keyring, etc.) - Caches supported flags map for performance This implementation maintains backward compatibility for single-file processing while enabling significant parallelization for multi-file scenarios.
