When the lua buffers are used, a variable number of stack slots may be used. Thus we cannot assume that we know where the top of the stack is. It was not an issue for lua < 5.4.3 (at least for small buffers). But 'socket:receive()' now fails with lua 5.4.3 because a light userdata is systematically pushed on the top of the stack when a buffer is initialized. To fix the bug, in hlua_socket_receive(), we save the index of the top of the stack before creating the buffer. This way, we can check the number of arguments, regardless anything was pushed on the stack or not. Note that the other buffer usages seem to be safe. This patch should solve the issue #1240. It should be backport to all stable branches. |
