From 49fe0b8fccf1a76d6e86bee6d787acf41437cac0 Mon Sep 17 00:00:00 2001 From: maxcleme Date: Tue, 3 Mar 2026 18:14:01 +0100 Subject: [PATCH] fix: allow multiple invocations with caching enabled This fix addresses the issue where calling setup-go multiple times with caching enabled in the same workflow would fail because the second invocation attempted to save to the same cache key. Changes: - Add tracking of processed cache keys using state variables to prevent duplicate cache save attempts - Add helper functions in constants.ts for state management: - getAlreadyCachedKey()/setAlreadyCachedKey(): Track keys already in cache - getPrimaryCacheKey()/setPrimaryCacheKey(): Track the primary key for each invocation - getCachedGoModPath()/setCachedGoModPath(): Track which go.mod was cached - Modify cache-restore.ts to store state about the cache operation - Modify cache-save.ts to check if cache was already saved for this go.mod path before attempting to save again - Add comprehensive tests for the multiple invocation scenario This enables workflows that need to setup Go with different configurations (e.g., different working directories) multiple times without cache conflicts.
