+ PCM: Expired reports get sent at the same time after a session restart
+ https://bugs.webkit.org/show_bug.cgi?id=221555
+ <rdar://problem/73724816>
+
+ Reviewed by John Wilander.
+
+ Since PCM data is now persisted, we need to address the case of a
+ session-restart after 24-48+ hours. We should not send all overdue
+ attributions in the same burst in case multiple have the same destination
+ and could identify a user cross-site.
+
+ This patch kicks off the timer to fire pending attributions on session-start
+ and sends one report at a time. If more than one overdue report exists
+ at any time, we schedule the timer for a random interval between 15 and
+ 30 minutes.
+
+ In theory this could result in some attributions never being sent if a
+ user keeps quitting and restarting a session. In practice this is
+ probably unlikely. Protecting the user's privacy is a hard requirement,
+ so we think possible starvation of some reports is the right tradeoff.

+ (WebKit::WebResourceLoadStatisticsStore::clearSentAttribution):
+ (WebKit::WebResourceLoadStatisticsStore::clearSentAttributions): Deleted.
+ * NetworkProcess/Classifier/WebResourceLoadStatisticsStore.h:
+ Remove unused SQLite query. Update the query to sort attributed PCM
+ by earliestTimeToSend, which seems important now that we send only
+ one overdue report at a time. Change the clearSentAttributions
+ function to take only a single attribution.
+
+ * NetworkProcess/NetworkSession.cpp:
+ (WebKit::NetworkSession::NetworkSession):
+ Convert m_privateClickMeasurement to a unique_ptr so we can wait to
+ create it after WebResourceLoadStatisticsStore is created. This ensures
+ that the call to create the SQLite database will run on a
+ background thread before we try to collect overdue PCM attributions.
