I'm working on Erlang bindings for FUSE. (http://code.google.com/p/ fuserl/) The ultimate goal is to make a distributed filesystem by leveraging Mnesia.
My first version of the fuse bindings used threads but the Erlang aesthetic is extreme concurrency so I thought reimplementing with poll was desirable. It works under Linux but fails under Mac. If you implement this, I could definitely test it. Production here is Linux but I have a Mac desktop so I like to have things work on it. I would love to see you work on this, but I can just spawn one extra thread (on the mac only), read the raw request off the kernel file descriptor and then socketpair-it over to the other thread and then just plug into my poll based architecture over there. Not super efficient but oh well. -- p On Jan 23, 8:20 pm, Amit Singh <[EMAIL PROTECTED]> wrote: > Tell me something: > > Why do you need this?
