Bug 195117 – Move NetworkProcess/Classifier/ResourceLoadStatisticsStoreCocoa.mm functionality into UIProcess/WebsiteData/Cocoa/WebsiteDataStoreCocoa.mm

• Component: New Bugs
• Status: RESOLVED FIXED

[Aaron]

Debugging a custom domain for ITP2 does not work for me at all on Safari Technology Preview: Release 76 (Safari 12.2, WebKit 14608.1.6.2). I followed the instructions here https://webkit.org/blog/8387/itp-debug-mode-in-safari-technology-preview-62/ and have tried deleting my history and cache and nothing.

When enabling debug mode, all i get in the terminal is

which doesn't include my custom domain.

Hi Aaron! Thanks for reporting. I will have a look.

Thanks John, In the meantime I managed to find an older version of Safari tech preview and got this to work

>> log stream -info | grep ResourceLoadStatisticsDebug

2019-02-28 21:45:27.346931-0500 0x385a2    Info        0x0                  26919  0    Safari Technology Preview: (WebKit) [com.apple.WebKit:ResourceLoadStatisticsDebug] Did set test-domain.org as prevalent resource for the purposes of ITP Debug Mode.

I think this is because WebKit/UIProcess/Cocoa/ResourceLoadStatisticsMemoryStoreCocoa.mm has not been moved to the network process. It could also make its calls over IPC.

WebKit/UIProcess/Cocoa/ResourceLoadStatisticsMemoryStoreCocoa.mm reads user defaults to allow developers to set a custom domain as permanently classified under ITP Debug Mode. This was broken by the recent move of ITP from the UI process to the network process.
