Well! I am ashamed to say I had never encountered the
mkfifo command. My only contact with "named pipes"
[snip interesting pipes discussion]
My only contact with named pipes was in the abomination that was
WebSphere 3.5.1 (you had choices of Java, Corba or "Named Pipes" as a
config option, forget what it was about, but pipes was the recommeded
setting, even on Nt 4)
Doesn't Oracle also have something similar for it's network config? I'm
sure I've seen pipes listed as an option instead of TCP when configuring
oracleNet, if they mean unix pipes that's fairly cool.
and everything works as expected on Unix. This also
works on cygwin EXCEPT that the <delete> does not fail
in Ant yet still fails to delete the pipe. But since
fifos would be implemented in god-only-knows-what-way
that is unsurprising. Cool.
Nice
As with most bits of unix (i.e. symlinks), it is a shame that the Nt
implementation isnt as seamless as the unix one. it means we can't
easily work with it to provide a portable pipe mechanism that the OS
handles. But if you can stick to unix, pipes make a good IPC
mechanism. And like I said, if you have a proper clustering OS, those
pipes work across machines in the cluster.
Would a minimal Java+JNI interface be a useful thing to have? Would
anyone use it? A portable library would be good for this kind of thing,
indeed a cross-platform mechanism for symlinks would be good too, or
wouldn't it?
