[fuse-emulator-devel] Remote debugger interface

[Philip K. <ph...@sh...>]

Hi all.

While living in the land of very limited connectivity last week (programming
without Stack Overflow is hard :-( ), I put together the first cut of a remote
interface for Fuse's debugger. With this you can simply telnet to Fuse and
run commands exactly as you would in the debugger itself. For example,
something like

$ telnet localhost 29552
Connected to localhost.
Escape character is '^]'.
break 0x1234 if z80:bc > 0x5678

would be exactly the same as typing "break 0x1234 if z80:bc > 0x5678" into
the debugger.

Sample code for this is in branches/feature-100-remote debugger.

There are a number of minor issues with this code right now, most obviously
the fact that the debugger's parser doesn't like the \r\n sequences which
get sent over telnet. We can fix that fairly easily though.

The bigger issue is security. Some sort of password-based authentication
would remove the ability for anyone with network access to your machine to
hijack your Spectrum session, but that would still leave things open to
replay attacks. Do we need to go that far (I think we probably do) and
if so, is there a solution which doesn't involve implementing TLS?

Any other thoughts of course also welcome. For avoidance of doubt, I don't
see this feature making our "August" release.

Cheers,

Phil
