• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Kate Cheney]

We should add a way to determine if a load is carrying user-identifiable data.

Looks good but let's work some more on naming and flip the currently used setting.

> Source/WebCore/ChangeLog:3
> +        PCM: Indicate if load data is user identifiable

Maybe add "network load"

> Source/WebKit/ChangeLog:3
> +        PCM: Indicate if load data is user identifiable

Ditto.

> Source/WebKit/NetworkProcess/NetworkDataTask.cpp:57
> +    return NetworkDataTaskCocoa::create(session, client, parameters.request, parameters.webFrameID, parameters.webPageID, parameters.storedCredentialsPolicy, parameters.contentSniffingPolicy, parameters.contentEncodingSniffingPolicy, parameters.shouldClearReferrerOnHTTPSToHTTPRedirect, parameters.shouldPreconnectOnly, parameters.isMainFrameNavigation, parameters.isMainResourceNavigationForAnyFrame, parameters.networkActivityTracker, parameters.isNavigatingToAppBoundDomain, parameters.shouldRelaxThirdPartyCookieBlocking, parameters.carriesUserIdentifiableData);

Hmm. It's unfortunate that we lose scoping here. If something said PCM, it would be much easier to understand what this parameter is for. I was hoping PrivateClickMeasurement::CarriesUserIdentifiableData would do it but it doesn't help on the call site. Ideas? Maybe carriesUserIdentifiableClickData or carriesUserIdentifiablePCMData?

> Source/WebKit/NetworkProcess/PrivateClickMeasurementManager.cpp:166
> +    loadParameters.carriesUserIdentifiableData = WebCore::PrivateClickMeasurement::CarriesUserIdentifiableData::Yes;

It's the opposite. :) This load does not carry user identifying data.

I'll make these changes, thanks John!

Will fix.

>> Source/WebKit/NetworkProcess/NetworkDataTask.cpp:57
>> +    return NetworkDataTaskCocoa::create(session, client, parameters.request, parameters.webFrameID, parameters.webPageID, parameters.storedCredentialsPolicy, parameters.contentSniffingPolicy, parameters.contentEncodingSniffingPolicy, parameters.shouldClearReferrerOnHTTPSToHTTPRedirect, parameters.shouldPreconnectOnly, parameters.isMainFrameNavigation, parameters.isMainResourceNavigationForAnyFrame, parameters.networkActivityTracker, parameters.isNavigatingToAppBoundDomain, parameters.shouldRelaxThirdPartyCookieBlocking, parameters.carriesUserIdentifiableData);

Yes I suppose this is still vague. I'm leaning toward carriesUserIdentifiablePCMData because I could see 'clickData' being confused with things unrelated to PCM.

Oops, I was thinking backwards after our conversation on naming -- good catch.

Good choice.

LGTM. I don't know why cq has a minus.
