Bug 189642 – [WebAuthN] Move time out control from WebProcess to UIProcess

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Jiewen Tan]

Move time out control from WebProcess to UIProcess. Otherwise, we will have a duplicate time out controller in AuthenticatorManager.

[Radar WebKit Bug Importer]

<rdar://problem/44476765>

[Jiewen Tan]

When we finished this task, we could add tests that:
1) In makeCredential, we could have a test that have exclude credentials that have the same credential id as existing one but not transport.
2) No authenticators can be discovered.

[Jiewen Tan]

3) Also, we could then add a test configuration to the discovery process to hide local authenticators.

4) Re-enable time out tests in:
public-key-credential-create-failure.https.html,
public-key-credential-get-failure.https.html.

Web IDL is using "unsigned long" so the correct C++ type is "unsigned".

unsigned timeOutInMsValue = std::min(maxTimeOutValue, timeOutInMs.value_or(maxTimeOutValue));

What guarantees there is always one timer needed at a time in the UIProcess? What prevents the AuthenticaticatorManager to process several requests in parallel?

Fixed.

Sure.

In both AuthenticatorManager::makeCredential and AuthenticatorManager::getAssertion which are the only entrances that take requests will immediately invoke the request callback if there is an existing one as we enforce one request at a time.
