Modify the key temporarily to force the creation of a fresh cache.
Do not guess what is inside your system's storage backend. Use administrative tools to audit your current cache footprint.
An action cache operates as a key-value store optimized for ephemeral build environments. The primary goal is to preserve expensive dependencies, compiled binaries, or workspace states between distinct execution runs. debug-action-cache
: Use developer command-line interfaces to query cache layers programmatically. For instance, you can leverage the GitHub CLI to view or purge entries directly from your terminal:
Understanding , restore keys , and cache scope is critical. Modify the key temporarily to force the creation
This is one of the most frustrating cache issues. You can see a cache exists, but the action stubbornly refuses to restore it. The debug logs will show a message similar to: [debug]No matching cache found for cache key '...', version '...' and scope '...' .
For developers who prefer the terminal or need to automate cache eviction across dozens of repositories, the GitHub CLI provides a swift solution. To list all caches in a repository: gh cache list --repo username/repo-name Use code with caution. To delete a specific corrupted cache key: An action cache operates as a key-value store
# List all active caches for the current repository gh cache list # Delete an explicit, problematic cache entry by its ID gh cache delete Use code with caution. 3. Perform Live Runner Interrogation
The debug-action-cache is not just a tool but a necessity for high-velocity engineering teams. Moving from an opaque caching model to a transparent, debuggable one ensures that build speed does not come at the cost of build reliability. To help me refine this draft, could you let me know:
: GitHub Actions enforces a strict 10 GB storage limit per repository . If your total cache size exceeds this threshold, GitHub will aggressively evict older caches using a Least Recently Used (LRU) algorithm. This can create unpredictable cache misses across concurrent pull requests.
Ensure that your path configuration uses universal glob patterns or platform-specific variables (like $ env.HOME ) to prevent the runner from caching empty directories.
