void StoreEntry::abandon ( const char *  context)

One of the three methods to get rid of an unlocked StoreEntry object. May destroy this object if it is unlocked; does nothing otherwise. Unlike release(), may not trigger eviction of underlying store entries, but, unlike destroyStoreEntry(), does honor an earlier release request.

StoreEntry * StoreEntry::adjustVary ( )

Updates mem_obj->request->vary_headers to reflect the current Vary. The vary_headers field is used to calculate the Vary marker key. Releases the old Vary marker with an outdated key (if any).

XXX: This method either should not exist or should not be virtual. Kids should not be forced to re-implement vappendf() logic. That logic should be implemented once, using other [Packable] APIs.

bool StoreEntry::shareableWhenPrivate

Nobody can find/lock KEY_PRIVATE entries, but some transactions (e.g., collapsed requests) find/lock a public entry before it becomes private. May such transactions start using the now-private entry they previously locked? This member should not affect transactions that already started reading from the entry.
