Bugs fixed:
* test cases were not loading the just built extension
New features:
* Ruby 1.9.3 compatibility
* Rake task for running tests
Minor changes:
* Warns to set the Informix environment variables when installing the gem
* gemspec file added
Caveats:
* It's no longer compatible with Ruby 1.8
* test cases require test-unit
0.7.3 2010-02-02
------------------
Bugs fixed:
* CursorBase#drop was raising an ArgumentError exception on Ruby 1.8.7
Caveats:
* Database#each and Database#each_hash removed. Use Database#foreach and
Database#foreach_hash instead.
0.7.2 2008-11-21
------------------
Bugs fixed:
* rb_cArray symbol was duplicated
Caveats:
* Database#each and Database#each_hash renamed to Database#foreach and
Database#foreach_hash respectively.
0.7.1 04/02/2008
------------------
Bugs fixed:
* The name of Informix resources were not unique. This problem was
introduced in 0.7.0. It doesn't affect previous versions.
* The documentation insisted that Database#execute is an alias for
Database#immediate.
* Cursor for Database#columns was prepared and declared every time it was
called.
0.7.0 03/31/2008
------------------
New features:
* Experimental support for the INTERVAL data type:
- year_to_month, day_to_fraction, from_months and from_seconds class
methods for creating an Interval object
- +@ and -@ unary operators
- +, * and / operations available with Integer, Rational, Date, Time
and DateTime objects
- methods for returning the respective fields of an Interval object
individually (years, months, days, hours, minutes and seconds)
- to_a method for returning the fields of an Interval object as an array
- methods for converting the Interval object to the given unit, where
apply (to_years, to_months, to_days, to_hours, to_minutes and
to_seconds)
- to_s method for displaying an Interval object as an string according
to ANSI SQL standards
- includes Comparable
* Database#version returns a struct with version information of the database
server.
* Database#each and Database#each_hash shortcut methods for declaring and
opening a cursor in a single step.
Contributed by Reid Morrison <reidmo at gmail>
* Database#execute is not an alias for Database#immediate any more.
It has become a shortcut for preparing and executing a statement in a
single step.
* SequentialCursor includes Enumerable
* Ruby 1.9 compatible
* More and better documentation
Bugs fixed:
* The documentation for class Error was not being recognized by rdoc
Remarks:
* Database.new deprecated in favor of Database.open
* Database#do was removed
* A lot of C code has been reimplemented in Ruby
* Modules and classes have been reorganized
* Database#execute still behaves the same, except that it can also accept
input parameters and return at most one record. Database#immediate is
more efficient though.
0.6.2 10/20/2007
------------------
Bugs fixed:
* Microsoft's cl compiler was failing due to a variable declaration
where it is not allowed.
Noticed by Joe Lanotte <joe.lanotte at comcast dot net>
0.6.1 10/13/2007
------------------
Bugs fixed:
* Database#columns was returning an empty array from within the
Informix ActiveRecord adapter
(ActiveRecord::ConnectionAdapters::InformixAdapter#columns) if
called for different tables. This bug was raising the following
error in Ruby on Rails:
undefined method columname=
Noticed by Andrés Rafael <aandresrafael at gmail dot com>
0.6.0 08/28/2007
------------------
New features:
* Test suite
* Error, Warning, and AssertionFailure classes replace RuntimeError when
raising exceptions.
Error class methods:
- message
- sql_code
- add_info
- []
- each
- to_s
- size, length
message and sql_code reference the first error message. Following
errors can be accessed through Error#[] as ExcInfo objects.
ExcInfo is a Struct with the following members:
- sql_code
- sql_state
- class_origin_val
- subclass_origin_val
- message
- server_name
- connection_name
See test/testcase.rb for a simple example of exception handling.
* Informix.version returns the version of this extension
* Database#do aliased as Database#execute
* More documentation
Remarks:
* Database#do is deprecated and will be removed in next versions. Use
Database#execute or Database#immediate instead.
* In case of Informix errors, RuntimeError objects are no longer raised.
Error, Warning and AssertionFailure objects are raised instead.
Acknowledgments:
I want to thank Edwin Fine <emofine at finecomputerconsultants dot com>
who contributed all the functionality of this release.
0.5.1 08/10/2007
------------------
Bugs fixed:
* When a DATETIME HOUR TO SECOND column had a value with leading zeroes
it was incorrectly interpreted.
Reported by Daniel Bush <dlb.id.au at gmail>
0.5.0 12/27/2006
------------------
New features:
* Easier to install
* BigDecimal accepted for input parameters
* BigDecimal used for instantiating DECIMAL and MONEY values
* Cursor, Statement, Slob and Database accept an optional block that
automatically frees resources after execution.
Based on ideas and pseudo-code by
Edwin Fine <emofine at finecomputerconsultants dot com> and me.
* Database#slob shortcut for creating Slob objects.
* Slob::Stat class implemented. Returned by Slob#stat, represents the
SLOB status. Methods: atime, ctime, mtime, refcnt and size. Includes
Comparable.
* Slob new methods: <<, rewind, stat, pos, pos=, lock, unlock,
estbytes, extsz, flags, maxbytes, sbspace,
extsz=, flags=,
atime, ctime, mtime, refcnt and size
* Thread safe
Remarks:
* DECIMAL and MONEY columns are no longer returned as Float. BigDecimal
is used instead.
Bugs fixed:
* If there was an error reading (ifx_lo_read) an SLOB, memory
allocated for the read buffer was not freed. Noticed by
Edwin Fine <emofine at finecomputerconsultants dot com>
* maxbytes option was ignored when creating an Slob object
* Documentation for Slob mentioned an RDRW constant, but it actually
is RDWR.
Special thanks to Guy Bowerman, Jonathan Leffler and Logan Capaldo for their
feedback and help.
