From 5d9db12a997ea30ae89f001ba447b3fea518f430 Mon Sep 17 00:00:00 2001 From: Aditya Menon Date: Wed, 26 Nov 2025 21:08:08 +0100 Subject: [PATCH] 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
