Bug 213678 – [GLIB] WebCryptoAPI tests failing after WPT update in r263598

• Component: New Bugs
• Status: NEW

[Diego Pino]

The following tests are failing:

  * imported/w3c/web-platform-tests/WebCryptoAPI/derive_bits_keys/hkdf.https.worker.html [ Failure ]
  * imported/w3c/web-platform-tests/WebCryptoAPI/derive_bits_keys/pbkdf2.https.any.html [ Failure ]
  * imported/w3c/web-platform-tests/WebCryptoAPI/derive_bits_keys/pbkdf2.https.any.worker.html [ Failure ]

The last two tests were added in the update. These tests have many passes but they fail on certain hashes schemes under certain sizes. Excerpt:

So to not hide these failures I prefer not to emit a baseline for those tests.

With regard to imported/w3c/web-platform-tests/WebCryptoAPI/derive_bits_keys/hkdf.https.worker.html, it had an own GLIB baseline with results better than the general baseline, but now is the opposite. It seems the test is not running properly:

The following tests started to timeout in r266118:

imported/w3c/web-platform-tests/WebCryptoAPI/derive_bits_keys/pbkdf2.https.any.html [ Timeout ]
imported/w3c/web-platform-tests/WebCryptoAPI/derive_bits_keys/pbkdf2.https.any.worker.html [ Timeout ]

In GTK both tests are consistently timing out. In WPE both tests are flaky (sometimes fail, sometimes timeout).
