- hosted (v4/tools/hosted.c): a line longer than the buffer is read to its
end and refused as too long. Before, fgets handed it over in 1025-byte
pieces and the last piece ran as a line of its own.
- bare metal (kernel/src/v4/sk_v4.c): the line editor takes 1024
characters, as the boot does, and a line typed past that is refused as
too long instead of being cut at 255 and run. V4_BOOT_LINE_TOO_LONG is
now reported at the prompt and while a line waits.
- engine (v4/src/exec.c): a store the node itself refuses (to "any port",
"which port", How or Have) left the opcode running on: !+ advanced A,
against node.h's FAULTS, and !p advanced P past the handler, into the
next fault kind's entry. A refused store now does nothing more; a store
that raises an error (D-18) still counts as made, but P stays the
handler's.
- test_port.c: both cases; they fail on the old exec.c (A 1017, P 901).
Engine-level tests (all v4/tests/test_*.c but test_host_*) pass at 32 and
64 bits; test_port also under ASan/UBSan. Not yet run: make -C v4 test,
test-32, hosted-check, and the three QEMU acceptance boots.
