Description Carlos Garcia Campos 2020-07-16 03:31:15 PDT
The memory store behaves differently than the database one, it only includes prevalent resources in the list, while the database store includes all resources when cooking blocking policy is All.

I'm pretty sure this change is correct.

Let's give John a day or two to do the final review, though, since it's his code.

Great catch! I am the engineer who added the ITP data summary, this change looks good. It would be nice to also update the ITP data summary test case in this patch before landing, looks like it is missing the piece of code which turns off database mode.

You can turn it off by adding:

 static bool doneFlag = false;
    [dataStore _setUseITPDatabase:false completionHandler: ^(void) {
        doneFlag = true;


right after calling 

[dataStore _setResourceLoadStatisticsEnabled:YES] 

in the GetResourceLoadStatisticsDataSummary test in TestWebKitAPI/Tests/WebKitCocoa/ResourceLoadStatistics.mm. The test should fail before your change, and pass after.
