I started looking at the rsync client - getting past the compiler and build system dependencies is a major chore. There are funny things like "typedef int int" in there that Watcom doesn't like; unraveling the macro pre-processor expansions to find the culprits takes time. I suspect that the change to use mTCP instead of Watcom will be far easier, but it takes a while to get to that point. Depending on the rest of the client, the speed difference may not be that great - that remains to be seen. (If it is mostly tied up in disk I/O or something cpu intensive then the TCP part might not make that much of a difference.) An rsync server? I need help ... there is not enough time in the world. (To that end I've been updating the Wiki documentation at the Google project hosting site - I've added a lot of design documentation lately.) On a slightly related topic, I've been thinking about what to do on the smaller machines to increase the amount of working storage. With a strict programming API I can use temp files as backing storage, kind of like implementing bank switched memory but backed by hard disk storage instead. Pretty slow, but better than not having any extra memory storage. One thing that frustrates me is that there is no way to make a 'bad' pointer on an 8088. Sure, the pointer can point to garbage, but there is no way to create a pointer that forces an interrupt. That would help things tremendously, especially when it comes to the part about testing and making the code robust. (It can be done with some extra hardware, but I don't think I'm that crazy yet.) Why the interested in memory allocation? I suspect that things like rsync are going to be limited by memory ... Also slightly related - Pasquale Villani.
