Debug-action-cache ⭐ Must See

GitHub does not allow you to manually edit a cache file, but you can delete it to force a clean slate. The most efficient way to purge a corrupted cache is through the GitHub CLI ( gh ). To list all current caches: gh cache list --repo owner/repository Use code with caution. To delete a specific problematic cache key: gh cache delete --repo owner/repository Use code with caution.

are too broad, you might be pulling in a cache from a completely different branch. 4. Advanced Troubleshooting Techniques HTTP Header Inspection:

Your local build works perfectly, but the CI fails with "File not found" or "Version mismatch" even though the package.json requirements.txt looks correct. The Culprit:

: The official fix was implemented in v4.1.0 . The action now correctly sets cache-hit to false even when the cache is not found. The simplest fix is to upgrade to the latest version of the action:

Always provide a list of ordered restore-keys . If an exact match fails, the runner can gracefully downgrade to a slightly older cache rather than starting from absolute zero. debug-action-cache

Why would you need to debug? Here are the top five disasters debug-action-cache helps you solve:

What (Node/NPM, Python, Docker, Go) are you currently trying to cache?

(Replace cache_id with the ID string retrieved from the list command above). 4. Best Practices for Bulletproof Action Caching

Bazel is renowned for its speed, largely due to its advanced caching mechanisms, particularly the . By caching the output of every build step (action) based on its inputs, Bazel avoids redundant work, providing near-instant builds for minor changes. However, when Bazel decides an action is "dirty" and must be re-executed, it results in a cache miss, slowing down your pipeline. GitHub does not allow you to manually edit

The debug-action-cache finds applications in various aspects of software development:

For further reading on diagnosing cache hits for remote execution, you can visit the Bazel Remote Execution Caching Debug page.

actions/cache in GitHub Actions involves enabling debug logging to inspect key generation, understanding that caches are immutable and branch-scoped, and addressing storage limits. Key troubleshooting steps include verifying To delete a specific problematic cache key: gh

There is no single "debug-action-cache" button, but you can implement the following strategies to investigate issues.

You expect: Restored from cache → fast builds But reality: Cache not found, or cache saved every time

Two different machines run the "same" code but produce different outputs, or a build passes locally but fails remotely.
