Ocamldebug for non-UNIX

Ocamldebug for non-UNIX

[Shmulik Regev]

Is some work being done on a debugger for the Mac/Windows OCaml versions ?

Thanks,

None that I know of.  The debugger from the Unix version relies
heavily on two Unix-specific features: Unix-domain sockets and the
fork() system call (used as a cheap and surprisingly efficient
checkpointing mechanism for the replay facility).  Under Windows at
least, a replacement for Unix-domain sockets could be found, but I
wasn't able to find an adequate checkpointing mechanism.

I was wondering the same a while ago. Xavier Leroy told me the problem is
that the debugger uses processes and sockets extensively in a way that are
incompatible with the Windows implementation of sockets.

I tried to compile the debugger under windows, which works. Unfortunately,
the code tries to do a select on a number of handles (sockets and file
descriptors) and then the windows/unix interface fails, since Windows
apparently has no select implementation to wait on file handles and sockets.

It looks like what we need is a wrapper for file handles that makes them
appear as sockets.

There may be other issues too, but that's as far as I investigated.
