Ruby mogilefs-client 3.10.0
A bunch of minor tweaks to reduce garbage and exceptions.
In addition to the existing :timeout and :fail_timeout options,
there is a new :connect_timeout directive for all connection
classes which only controls the time spent waiting for a TCP
connection. This defaults to the same value as the existing
:timeout option (3 seconds); but users are advised to lower
it to match ideal network conditions.
For users of Ruby 2.3+, this release takes advantage of
exception-less Socket#connect_nonblock using "exception: false".
Users of Ruby 2.1+ will also benefit from "exception: false"
usage for read_nonblock and write_nonblock calls.
kgio is no longer be useful with this release with Ruby 2.3+
This release also fixes a Ruby 1.8.7 compatibility bug for
non-kgio users. However, this may be the last 1.8.7-compatible
release. Fwiw, I wanted to remove Ruby 1.8 support around 5
years ago but several users were against it. Maybe nobody will
complain, this time...
