io_splice 3.0.0 - kinder, gentler Linux zero-copy
This release adds the IO.trysplice and IO.trytee interfaces to avoid expensive EAGAIN exceptions for non-blocking I/O. There is no IO.tryvmsplice method as we still haven't figured out a good use for IO.vmsplice in Ruby, and non-blocking I/O with iovecs is just painful! If you want more zero-copy fun without needing mmap(2), check out the "sendfile" RubyGem and IO.copy_stream (1.9). As of Linux 2.6.33+, sendfile(2) can copy mmap-able files to +any+ descriptor, not just sockets. Please email us at ruby.io.splice@librelist.com if you can think of a good use for IO.vmsplice or IO.trysplice in Ruby.
