Ruby-oci8 2.1.8 is released. This is the Oracle module using OCI8 API.

  http://rubyforge.org/projects/ruby-oci8/

New Features

···

------------

### Send and receive timeouts

New methods {OCI8#send_timeout}, {OCI8#send_timeout=},
{OCI8#recv_timeout} and {OCI8#recv_timeout=}
were added. They are available on Oracle 11.1 or upper.

Use them at your own risk because they use undocumented OCI handle attributes.

### Cancel read system calls not to prevent ruby process termination

When network quality is poor and incoming packets are lost irregularly,
the ruby process termination may be blocked until TCP keepalive time (2 hours).

By setting [OCI8.properties[:cancel_read_at_exit]](OCI8.html#properties-class_method)
true, read system calls, which may wait incoming packets, are cancelled at exit.
See: [github issue #56](https://github.com/kubo/ruby-oci8/issues/56)

This feature is disabled by default because it uses [unusual
technique](https://github.com/kubo/plthook)
which hooks read system calls issued by Oracle client library and it
works only on
Linux, Windows and OSX.

### RGenGC

Object allocation code is rewritten to use
[RGenGC](http://www.infoq.com/news/2013/12/ruby21).

Fixed Issues
------------

- Raises an exception when a closed OCI8 object is used.
    Using a closed cursor causes various problems such as segmentation
    fault, nil comparison error and so on.
    See: [github issue #61](https://github.com/kubo/ruby-oci8/issues/61)
    and [github issue #62](https://github.com/kubo/ruby-oci8/issues/62)

    (reported by Mike Bourgeous)

- Fix "RuntimeError:executing in another thread"
    when a closed connection is used. This bug was introduced by
    the previously listed issue.
    See: [github issue #64](https://github.com/kubo/ruby-oci8/issues/64)

    (reported by Yasuo Honda)

- Fix SEGV when a temporary LOB is freed by GC while reading another
    lob and the ruby version is 2.0.0 or upper.

- Skip rollback on logoff when no transactions are in progress.

- Fix a broken link in README.md.
    See: [github issue #67](https://github.com/kubo/ruby-oci8/issues/67)

    (reported by Zloy)

- Don't use SYM2ID on ruby 2.2.0 or later not to make symbols unGCable
    by [Symbol GC](http://www.infoq.com/news/2014/12/ruby-2.2.0-released).

Hi! Happy Wednesday~!
Github: https://github.com/gogotanaka/RubypeHP: http://gogotanaka.github.io/rubype.github.io/Rubygems: https://rubygems.org/gems/rubype
This gem brings you advantage of type without changing existing code's behavior. (super clean!!! wow)
All you need to do is to install gem and require 'rubype' (too easy!!! wow)
Good point:$ Meaningful error$ Executable documentation$ Don't need to check type of method's arguments and return.$ Type info itself is object, you can check it and even change it during run time.
Bad point:$ Checking type run every time method call... it might be overhead, but it's not big deal. $ There is no static analysis.

Thanks!
