[configuration] 1.0-RC1 Released!
FYI,
Finally, 7 months and 3 weeks after configuration was first promoted from
the Sandbox, we finally have a 1.0 Release Candidate 1. Please bear with me
if I made any significant mistakes during this process as it was my first
time attempting to release anything. I want to thank all the people who've
contributed to Configuration since it's move out of the Sandbox, and to all
the other developers who contributed to Configuration when it was part of
JServ and Turbine.
A couple of notes:
1) The jar is available online through ibiblio:
http://www.ibiblio.org/maven/commons-configuration/jars/
2) The source was tagged as CONFIGURATION_1_0_RC1. This tag had been
applied at somepoint to some older chunks of Configuration, probably in an
earlier abortive attempt. I moved the tag.
3) I'm headed out of town on vacation and won't be back till Sept 4th. If
no major issues have been discovered, and no one has released it, I'll
attempt to do it them. However, if someone wants to step up to the plate to
do a vote and release after giving rc1 a week to simmer, I'd be eternally
grateful.
4) The site docs are updated. However, after doing the update, I realized
that the JavaDocs aren't being generated, so the docs are older. There
haven't been any API changes to Configuration, so it shouldn't be the end of
the world, but if someone wants to look at why the JavaDocs won't generate,
that would be great.
5) Documentation is somewhat lacking.. It would be nice to do another turn
of the crank. Or, maybe get an article written! I'd be glad to
help/coauthor with anyone.
Cheers,
Eric Pugh
The change log is rather long, so reading it online might be better, but
here goes:
New Features:
o HierarchicalConfigurationXMLReader stores comments as text nodes Issue:
30597. Thanks to Oliver Heger.
o project.xml contains bad dependencies Issue: 30648. Thanks to Ricardo
Gladwell.
o clearXmlProperty doesn't remove list properties completely Issue: 30234 .
Thanks to Brent Worden.
o new ConfigurationDynaBean Issue: 30545. Thanks to Ricardo Gladwell.
o new ConfigurationMap and ConfigurationSet Issue: 29611. Thanks to Ricardo
Gladwell.
o Added save methods in XMLConfiguration similar to PropertiesConfiguration
to save the configuration to another file (bug 29721).
o Added a save() method to PropertiesConfiguration and save(Writer out),
save(OutputStream out), save(OutputStream out, String encoding) to
BasePropertiesConfiguration.
o Direct support of XML via DOM. New classes DOMConfiguration and
HierarchicalDOMConfiguration.
o Changed CompositeConfiguration to extend from AbstractConfiuration. This
means that the behavior of CompositeConfiguration is much similar to
others
like PropertiesConfiguration in handling of missing keys, interpolation,
etc.. Previously CompositeConfiguration had quite a few differences.
o The Configuration interface now supports BigDecimal and BigInteger
numbers.
o ConfigurationException is now thrown by public methods instead of
Exception
or IOException or whatnot.
o For configuration based on properties files, allow characters like \n etc
to be escaped and unescaped.
o New DatabaseConfiguration that uses a database to store the properties. It
supports 2 table structures : one table per configuration (2 colums
key/value) one table for multiple configurations (2 columns key/value + 1
column for the name of the configuration)
o ConfigurationFactory now supports the hierarchicalDom4j element in
configuration definition file
o ConfigurationFactory now supports two types of properties files,
additional
and override. Additional properties add each other together. Override
override each other. This allows you to have a single property that is
either aggregated from a number of sources, or have a property that is
overridden according to a specific order of sources.
o Added AbstractConfiguration to make it easier to create subclasses by only
having to implement the methods required.
Fixed bugs:
o Problem adding property XMLConfiguration Issue: 30598. Thanks to Ricardo
Gladwell.
o DatabaseConfiguration doesn't support List properties. Issue: 29734.
o Fixed several bugs related to XMLConfiguration: 30074 - Can't add a new
property as an attribute in XMLConfiguration 30205 - XMLConfiguration
doesn't support attribute names with a dot 30209 - XMLConfiguration
doesn't
ignore comments 30212 - XMLConfiguration.save() doesn't escape reserved
characters
o List values are now properly stored as comma separated values in the
Properties object returned by ConfigurationConverter.getProperties() (Bug
29607)
o Tokens like ${ref} in a PropertyConfiguration are now properly saved (Bug
29366).
o The getList() method of a CompositeConfiguration now returns the list
composed of the elements in the first matching configuration and the
additional elements found in the in memory configuration (Bug 28660).
o SubsetConfiguration returns a List on getList(). AbstractConfiguration
wouldn't properly deal with a List, only with a Container for getList()!
Thanks to jschaible for the unit test.
o Reapply the ConfigurationXMLDocument that went missing during migration
out
of sandbox.
o ClassPropertiesConfiguration Additions Use the classloader of class that
is
provided by the constructor. Add a constructor that indicates whether to
use relative or absolute. Change getPropertyStream to utilize the relative
or absolute flag. Add a test case that checks that absolute paths work.
o JNDIConfiguration.getKeys() Addition The JNDIConfiguration.getKeys()
method
was returning an unsupported operation error. However, this is an
important
method to have supported.
o CompositeConfiguration.getKeys() Fix The CompositeConfiguration.getKeys()
method was returning an unordered list of configuration values. However,
many apps expect the order that keys are returned to be the order they are
added into the properties file.
Changes:
o Removed the DOM4J implementations in favor of the DOM ones.
DOMConfiguration has been renamed to XMLConfiguration, and
HierarchicalDOMConfiguration to HierarchicalXMLConfiguration. The elements
parsed by the ConfigurationFactory have been changed accordingly.
o Introduced a ConversionException thrown when the value of a property is
not
compatible the type requested. It replaces the ClassCastException and the
NumberFormatException thrown previously.
o Update build to not include test configuration files in resulting jar.
o Refactored JNDIConfiguration to use AbstractConfiguration.
o Fixed bug 27427 by refactoring out the subset logic into a
SubsetConfiguration.
o Apply ASL 2.0 license. Thanks to Jeff Painter for scripting the
conversion!
o Removed "defaults" from BaseConfiguration. Defaults are now done via using
a CompositeConfiguration, either directly or via a ConfigurationFactory.
if
you want to save changes made to a Configuration, then you use a
CompositeConfiguration and get back the inMemoryConfiguration that has the
delta of changes. Added a bit of documentation on this.
o Bugzilla 16504 Enhancement: Configuration Comparator
o Bugzilla 26694 (BaseConfiguration: containsKey ignores default
properties).
I have changed it so that now the defaults are paid attention to.
o Change all Vector objects to List objects.
o AbstractConfiguration addProperty now delegates to an abstract
addPropertyDirect implemented by BaseConfiguration.
o Changed getString() method to throw a NoSuchElementException instead of ""
if the configuration property doesn't exist.
Removed features:
o ConfigurationXMLDocument removed until post 1.0.
