[tcljava-dev] Sockets in Jacl...

[Neil M. <NM...@uk...>]

OK - I have hacked away at the weekend, and have come up with an
implementation of sockets in Jacl. Both client and server sockets work
(although I haven't run the socket tests on them yet). The error
messages aren't what Tcl gives yet, and there are some limitations:
* There is no fileevent command, so you can't handle more than one
connection at a time on a server socket (at least, I couldn't figure out
how).
* The -async flag to client sockets is not implemented.
* fconfigure doesn't do anything in current CVS jacl (apart from parse
its arguments). I haven't updated it to add the socket-specific options.
* Jacl seems to behave wrongly in terms of events. In the shell,
TCL.ALL_EVENTS flag is passed when doing Notifier.doOneEvent(), which
causes me to process socket connection events, even though these
shouldn't be processed unless an event loop has been entered (with
[vwait]). This is different behaviour to tclsh.

Anyway, I'm gonna clean up the code, and then create a patch for anyone
who wants a try. And if someone who has developer access to the TclJava
project wants to add this, they're more than welcome (might need a bit
of polishing first, though).
PS - I've only tested so far on 1.2.6, so some of these issues may have
gone away in CVS latest.
