Fixes #216

Summary of Changes

In src/services/github.js, openDB() opens an IDBDatabase connection handle for cached API queries (cacheGet, cacheSet, cacheClear), but the database handle was not being closed after transaction completion.

This PR adds explicit db.close() calls within tx.oncomplete, tx.onerror, and tx.onabort callbacks across all cache service methods.

Verification

  • Tested IndexedDB cache operations for GitHub API requests.
  • Verified that database connection handles are properly closed when transactions finalize, preventing memory leaks and handle accumulation in browser DevTools.

Summary by CodeRabbit

  • Bug Fixes
    • Improved cache read reliability by handling transaction completion, errors, and interruptions consistently.
    • Ensured expired or unavailable cached data returns an empty result instead of stale or incomplete data.
    • Improved cache update and clearing operations when transactions are interrupted.
    • Ensured database connections are closed after cache operations complete.

…ub.js

Closes AOSSIE-Org#216

Ensures that IndexedDB database connection handles opened by openDB() in cacheGet, cacheSet, and cacheClear are explicitly closed on transaction completion, error, or abort. This prevents active database handle accumulation and memory leaks during large organization queries.

Walkthrough

IndexedDB cache operations now use transaction lifecycle handlers. cacheGet resolves cached values only after successful completion and closes the database in all paths. cacheSet and cacheClear also close connections and handle transaction aborts.

Changes

IndexedDB cache lifecycle

Layer / File(s) Summary
Transaction completion and cleanup
src/services/github.js
cacheGet resolves after transaction completion and returns null for expired, failed, or aborted transactions. cacheSet and cacheClear close the database on completion, error, and abort, and resolve false on abort.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 939fb

The change improves IndexedDB connection cleanup, but a failed cache clear can still be shown as successful in settings because the result is not checked. This is a bounded correctness issue that should remain under owner awareness or be fixed before merging.

A rabbit checks the cache at dawn
Old connections now are gone
Reads wait for transactions bright
Writes close handles left and right
Abort paths finish clean and light

@Dotify71 Quick review complete. I found no blocking issues.

The three cache helpers now close the IndexedDB connection for transaction completion, error, and abort paths. cacheGet also waits for transaction completion before it returns the cached value.

One non-blocking gap remains: the repository has no IndexedDB cache tests. A future test should verify db.close() for successful, error, and abort transaction paths.

⚠️ Action not completed
