Introduce time-based website data eviction
https://bugs.webkit.org/show_bug.cgi?id=313865
rdar://175894273
Reviewed by Ben Nham.
For users with ITP disabled, website data can accumulate indefinitely. Add a
time-based eviction mechanism that deletes
data for origins not accessed within a configurable threshold (default 180
days). Eviction currently runs once at
session initialization, skipping active and persisted origins. The eviction
currently only include types written by
Storage APIs (so not including cookies and credentials). The feature is
currently gated on timeBasedEvictionEnabled,
which is off by default.
This patch includes a drive-by fix that we don't update modification timestamp
of origins with LocalStorage operations
since they don't go through normal quota check (LocalStorage has its own quota).
Tests: TimeBasedEviction.Basic
TimeBasedEviction.IndexedDBReadUpdatesTimestamp
TimeBasedEviction.LocalStorageReadUpdatesTimestamp
TimeBasedEviction.CacheStorageReadUpdatesTimestamp
TimeBasedEviction.FileSystemAPIReadUpdatesTimestamp
