Likely this regression was introduced in r243339 (Cache API and IDB space usages should be initialized on first quota check https://bugs.webkit.org/show_bug.cgi?id=195707). It has been failing since then onwards. --- /WebKit/WebKitBuild/Release/layout-test-results/http/tests/IndexedDB/storage-limit-1.https-expected.txt +++ /WebKit/WebKitBuild/Release/layout-test-results/http/tests/IndexedDB/storage-limit-1.https-actual.txt @@ -12,10 +12,9 @@ db = event.target.result store = db.transaction('store', 'readwrite').objectStore('store') request = store.add(new Uint8Array(300 * 1024), 'key') -PASS 'error' in request is true -PASS request.error.code is DOMException.QUOTA_EXCEEDED_ERR -PASS request.error.name is "QuotaExceededError" +FAIL Add operation should fail because storage limit is reached, but succeeded.

This has started to pass reliably since some revision between r243889 and r243922. Closing bug and updating expectations.
