Subject: [ANN] kgio library / RubyGem
Date: Mon, 27 Sep 2010 20:03:02 -0700 [thread overview]
Message-ID: <20100928030302.GA3452@dcvr.yhbt.net> (raw)
Hello all,
I've released kgio, a kinder, gentler I/O library for Ruby. Some of its
features are useful for Unicorn, and all of it is useful for Rainbows!
I intend to make kgio a requirement for both Unicorn and
Rainbows!/Zbatery. I'm comfortable with the code, but extra testers and
extra eyes to review it would be helpful (it's nearly all C).
There were several factors leading the creation of this library:
1. The performance loss from Ruby 1.9.2 due to extending exceptions
with IO::Wait{Read,Writ}able is annoying. While it's partly
fixed[1] and fixable[2] for 1.9.3, it could be a while before
1.9.3 is available. Unicorn currently does non-blocking accept
very aggressively.
2. (Rainbows! only) Slicing partially written strings for
non-blocking I/O in gets painful with Ruby 1.9, it's much easier
(at least for me) to do this in C and kgio_trywrite allows
exactly that, returning the unwritten portion of a string.
3. (Rainbows! only) It offers hooks for using alternative
methods to switch execution contexts (experience taken from
building the FiberSpawn/FiberPool modules).
4. (philosophical) I've never considered EAGAIN/EINPROGRESS
"exceptional" conditions when explicitly doing non-blocking
I/O, and thus unworthy of raising exceptions.
kgio currently passes all tests on on Linux 2.6 (1.9.{1,2},
1.8.{6,7}, rbx 1.1) and FreeBSD 7.0 (1.8.7).
