Method DropReferencesTo

src/SHAHashSet.cpp:1021–1046

void CAICHHashSet::DropReferencesTo(const CKnownFile* file)
{
	// Pointer-value strip of any in-flight AICH recovery request that
	// names `file`. Called from MuleNotify::KnownFileBeingDestroyed
	// (GuiEvents.cpp) before the CKnownFile / CPartFile is freed by
	// CPartFile::Delete() or CKnownFileList::PruneDuplicates. Without
	// this, the pending request would deref the dangling partfile
	// when the recovery data eventually arrives (RequestAICHRecovery's
	// existing IsPartFile() guard at line ~990 catches some cases
	// but a freed-then-reused pointer can spoof that check and
	// route recovery to the wrong file).
	//
	// CPartFile inherits from CKnownFile (single inheritance, same
	// address), so the cast in the comparison is no-deref. Same-
	// thread call (main thread) so no synchronisation needed on
	// the static list beyond the normal amule single-threaded GUI
	// contract.
