Bug 183641 – Resource Load Statistics: Add clearing of storage access to WebResourceLoadStatisticsStore::clearInMemory()

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[John Wilander]

WebResourceLoadStatisticsStore::clearInMemory() should clear out all storage access entries in the network process. Right now, we have layout test failures because of one test providing access to another.

To fix your crash, you may want to try:
if (canSendMessage())
    send(Messages::NetworkProcess::RemoveAllStorageAccess(sessionID), 0);

Thanks, Chris! I will try this. If it works I should add that check to all the other message sends I have in this proxy.

if (canSendMessage()) sadly did not fix the issue.

It's marked as [ Pass ] in one more place. :(

I think chances are that networkProcess() returns null here. Try adding a null check for processPool->networkProcess().
