Description

If the client needs to abort mid-transfer, there is no way to tell the server. The client just disconnects, leaving the server to potentially hang on a read or write.

Location

src/shared/protocol.h (NEED STATUS enum)
src/shared/protocol.c
src/server/server.c

Suggested Fix

Add STATUS_CANCEL message. Client sends it before disconnecting. Server receives it and aborts the transfer gracefully (closes files, sends STATUS_OK, exits).

Severity

high
