nanomsg support

[romix]

Richard,

You've experimented with ZeroMQ already. May be nanomsg could be used instead of ZeroMQ?

nanomsg claims to be nextgen ZeroMQ, fully POSIX API compliant, faster, written in C, MIT-licensed. And there are a few Lua bindings available.

Hell, I clearly haven't been paying attention. Yeah. This is exactly
what I need. Small, clean, fast and written by the same guy.

ZeroMQ is already out of Shine anyway (the bindings are in a separate
github repo now). Nanomsg will solve my threading library (I can ditch
that stoopid Pipe implementation now).

Thanks for this.

[romix]

You're welcome! :-)

Initial support for nanomsg is in and integrated into the event loop. So nanomsg sockets can be mixed with regular sockets, and fibers as well as threads and nothing should block.

Cool! Thanks!

But it does not build for me:

../boot/bin/shnc  -n "sys.thread"    sys/thread.shn   shine/build/sys_thread.o
../boot/bin/shnc  -n "sys.nanomsg"   sys/nanomsg.shn   shine/build/sys_nanomsg.o

Try now?

[romix]

Yep. Works :-)

[richardhundt]

forgot to push earlier :(

notice that it does require to be compiled with -fPIC, or shine doesn't build

I had to patch lib/Makefile

${DEPDIR}/nanomsg/Makefile:
  cd ${DEPDIR}/nanomsg && ./autogen.sh && CFLAGS='$(CFLAGS) -fPIC ' ./configure --prefix=${BUILD} --with-pic

to fix that.

I've bumped nanomsg submodule in master and it doesn't seem to be a problem on my ubuntu VM. Could you check if this patch is still needed?

[dvv]

will do. is there any nanomsg sample btw?

[dvv]

CFLAGS='$(CFLAGS) -fPIC ' 

is needed, seems.
