Bug 170763 – Resource Load Statistics: Check both origins and cookieHostNames for domain matches in data removal

• Component: WebKit2
• Status: RESOLVED FIXED

[John Wilander]

WebsiteDataRecords either have origins, cookieHostNames, or both depending on their WebsiteDataTypes. We need to check both for a match during data record removal.

Crash is unrelated to this patch.
This is a new regression tracked in bug 170754

I think this looks good, but we need a WK2 reviewer.

> Source/WebKit2/UIProcess/WebsiteData/WebsiteDataRecord.cpp:120
> +bool WebsiteDataRecord::validForTopPrivatelyControlledDomain(const String& topPrivatelyControlledDomain)

It seems like this could be 'const'.

> Source/WebKit2/UIProcess/WebsiteData/WebsiteDataStore.cpp:501
> +    fetchData(dataTypes, fetchOptions, [topPrivatelyControlledDomains, completionHandler, this](auto existingDataRecords) {

Since ebsiteDataStore::fetchData does a WTFMove on the records it passes to this completion handler, it seems like "auto existingDataRecords" should really be "auto&& existingDataRecords".

> Source/WebKit2/UIProcess/WebsiteData/WebsiteDataStore.cpp:507
> +                    matchingDataRecords.append(dataRecord);

Maybe this could be WTFMove'd into matchindDataRecords? Might need to make "auto& dataRecord" -> "auto&& dataRecord"? Not sure if that works.

> Source/WebKit2/UIProcess/WebsiteData/WebsiteDataStore.cpp:508
> +                    domainsWithMatchingDataRecords.append(topPrivatelyControlledDomain);

Maybe this could be WTFMove'd, too?

Thanks, Brent! I could fix all the things you mentioned except for the last WTFMove of topPrivatelyControlledDomain. I suspect the compiler gets upset because I'm moving an element in the set I'm iterating over but if you can spot a mistake I've made I'm happy to try again I had to introduce move semantics for that vector all the way from the call in WebResourceLoadStatisticsStore::removeDataRecords().

Can this be const auto&?

Maybe matchesTopPrivatelyControlledDomain would be a better name than validForTopPrivatelyControlledDomain.
