* fix: skip cache refresh for shared cache paths to prevent race conditions When multiple helmfile processes run in parallel (e.g., as ArgoCD plugin), they share the same OCI chart cache in ~/.cache/helmfile. One process could delete and re-download (refresh) a cached chart while another process was still using it, causing "path not found" errors. This fix: - Adds isSharedCachePath() helper to detect shared cache paths - Skips chart deletion/refresh for paths in the shared cache directory - Users can force refresh by running `helmfile cache cleanup` first Fixes #2387 Signed-off-by: yxxhero <aiopsclub@163.com> * docs: document OCI chart caching behavior and multi-process safety Add documentation for: - OCI chart cache location and behavior - How to force cache refresh with `helmfile cache cleanup` - Multi-process safety when using shared cache - Cache management commands (info, cleanup) Signed-off-by: yxxhero <aiopsclub@163.com> * fix: address review comments for shared cache handling - Return error instead of chartActionDownload for corrupted shared cache - Change refresh skip log from Debugf to Infof for user visibility - Add t.Helper() to createTestLogger test helper Signed-off-by: yxxhero <aiopsclub@163.com> * fix: handle symlinks and add debug logging in isSharedCachePath - Use filepath.EvalSymlinks to resolve symlinks before path comparison - Add debug logging when filepath.Abs fails - Add test case for symlink to shared cache directory Signed-off-by: yxxhero <aiopsclub@163.com> * fix: address copilot review comments - Include underlying error in corrupted cache error message - Add cleanup for test directories created in shared cache - Clarify --skip-refresh flag documentation Signed-off-by: yxxhero <aiopsclub@163.com> * fix: handle edge case when chartPath equals sharedCacheDir - isSharedCachePath now returns true for exact match with cache dir - Add test case for exact match with shared cache directory Signed-off-by: yxxhero <aiopsclub@163.com> * test: add integration test for acquireChartLock shared cache behavior Add TestAcquireChartLockSharedCacheSkipRefresh to verify that acquireChartLock returns chartActionUseCached instead of chartActionRefresh when the chart exists in the shared cache, even when refresh is requested. This tests the core fix for the race condition issue #2387. Signed-off-by: yxxhero <aiopsclub@163.com> --------- Signed-off-by: yxxhero <aiopsclub@163.com> |
