= Release History

== 3.1.0 / 2018-02-03 Charlie Savage

* Add Gemfile. #146. (Dorian Marié)
* Remove duplicate hash key in setup.rb. #147. (Dorian Marié)
* Fix gemspec by requiring Date. #149 (utilum)
* Restore default internal encoding after tests are completed. #123 (Charlie Savage)
* Remove duplicate method definitions. #145. (Charlie Savage)
* Remove SchemaElement#minOccurs and SchemaElement#maxOccurs since they actually did not work (Charlie Savage)

* Add Travis Build support (Charlie Savage)
* Fix Fixnum deprecation (Charlie Savage)
* Cleanup schema code (Charlie Savage)
* Update Visual Studio project to 2017 (Charlie Savage)

== 3.0.0 / 2017-02-07 Charlie Savage

* Revamp how libxml-ruby manages memory.  Instead of trying to return the same ruby object for each xmlnode,
  the bindings now create wrapper ruby objects as needed which are then freed at the end of use.
  This allows most memory management to be handled by libxml itself. Ruby only manages the lifespan of
  documents and parent xml nodes.  When those go out of scope, the underlying libxml objects are also freed.
  This implementation requires almost no overhead, plays nicely with Nokogiri and appears to work much
  better  (Charlie Savage).

* Change XML::Node#eql? API.  Nodes are now considered equal only if they wrap the same underlying
  libxml node.  Previously, they would also be considered equal if they contained the same content
  (Charlie Savage)

* Change XML::Reader.expand API. Previously it would automatically instantiate a reader document so
  the an xpath expression could be used to search the returned node.  Now you should first call
  reader.doc  (Charlie Savage)

* Update Visual Studio project for Visual Studio 15 - requires ruby 2.4+ (Charlie Savage)

* Remove APIs that have been deprecated for several years (Charlie Savage)

== 2.9.0 / 2016-06-13 Charlie Savage

* Revamp libxml-ruby's memory management to not cause crashes when used with Nokogiri (James Laird-Wah)
* Fix garbage collection issue that sometimes caused the library to hang (Charlie Savage)
* Improved multi-threading support (Charlie Savage)
* Fix crash sometimes caused by a xml node being being freed twice (Charlie Savage)
* Fix memory leak when setting the text content of a node (Charlie Savage)
* Set a default task in the Rakefile - use "test" (Robert Haines)
* Add "hanna_gudao" gem and add "rake-compiler" to develpoment dependencies (Robert Haines)
* Use Process.getrlimit instead of `ulimit` in the tests (Robert Haines)
* Build on smartos (Steven Williamson)
* Fix compiler warnings (Charlie Savage)
* Add Xcode project for easier debugging on OSX (Charlie Savage)
* Switch from unit test to minitest (Charlie Savage)

* In XML::Writer prevent writing to io while being GCed (Brett Gibson)

== 2.7.0 / 2013-08-13 Charlie Savage

* Don't call rb_warning in GC mark function (Dirkjan Bussink)
* Set libxml error handler when a libxml-ruby error handler is set (Geoffrey Giesemann)
* Fix tests for nil TypeErrors for ruby 2.0=< (Geoffrey Giesemann)
* Fix segmentation fault for issue #62 (Charlie Savage)
* Add #node_type method to dtd (Charlie Savage)
* Fixing equality check of LibXML::XML::Error against other objects (Michał Szajbe)

  with older versions of libxml.
* Various updates/fixes to new XML::Writer class and update how flushing works (julp)

== 2.5.0 / 2013-01-27 Charlie Savage

* Compatibility with older versions for IO::write (rb_io_bufwrite is specific to ruby >= 1.9.3?)
  and symbols are VALUE not ID (julp).
* Fix version for xmlTextWriterSetQuoteChar, it appeared in libxml2 2.9.0, last version (julp)
* Update use of LIBXML_VERSION (julp).
* Fix misuse of rb_scan_args (julp).
* Update documentation, including DTD docs and added XML Writer (julp).
* Added a new XML::Writer class (julp).
* Improved xml reader api and add namespace support.  Note that passing a numeric value
  to XML::Reader::move_to_attribute has been deprecated. Instead you should now
  use #move_to_attribute_no.  (julp).
* Improve error handling and messages (Jarl Friis)

== 2.4.0 / 2012-12-14 Charlie Savage

* Support libxml 2.9.0 (Daniel Veillard)

* Extensive new interfaces for xml schema functionality including suppor for
  schemal elements, types, facets and attributes (Anton Sozontov)

== 2.3.3 / 2012-07-01 Charlie Savage

* Add LibXML::XML::Error.get_handler (Carsten Zimmermann)
* Fix variable name in example (Marcus)

== 2.3.2 / 2012-03-20 Charlie Savage

* Define various canonicalize constants to support libxml2 versions
  older than 1.1.25 (thanks Apple!)

== 2.3.1 / 2012-03-20 Charlie Savage

* Yanked - didn't fix the OSX canonicalize issue

== 2.3.0 / 2012-03-18 Charlie Savage

* Add ability to insert new PI-nodes into the xmltree (Axel Struebing).

* Added full pass-through access to libxml2 xmlC14NDocDumpMemory method via
  LibXML::XML::Document#canonicalize method with optional arguments.

* Added full test data for C14N based off of W3C spec. 
  (http://www.w3.org/TR/xml-c14n#Examples)

* Update sax handler to support encodings on Ruby 1.9 and higher.

== 2.2.2 / 2011-08-29 Charlie Savage

* ++API CHANGE+++

Reader#relax_ng_validate now takes a RelaxNG object.  This is
what the documentation has always said it takes, but it previously
took a string.  In addition, it now returns true or false instead of 0 or -1.

Reader#schema_validate now takes a Schema object.  This is
what the documentation has always said it takes, but it previously
took a string.  In addition, it now returns true or false instead of 0 or -1.

Fixes GitHub issue #30.

* Added Parser::Context#close and HTMLParser::Context#close methods that
  allow the underlying io stream (file, string, etc) to be closed.  Once a
  parser is done parsing its data, it now calls one of these methods.
  This means that if you parse thousands of files at the same time,
  without running Ruby's garbage colllector, you won't get a too
  many files open error.  Fixes GitHub issue #29.

* Fixed bug where Node#inner_xml caused an error when it had no child nodes.
  Fixes GitHub issues #31

* Don't require 'rake' in the gemspec to avoid annoying Bundler bugs

== 2.2.1 / 2011-08-13 Charlie Savage

* Packaging fix - include the custom .def file in the gem.

== 2.2.0 / 2011-08-09 Charlie Savage

* Update encoding support for Ruby 1.9 so that libxml-ruby returns
  strings encoded in UTF-8.  This change was required since libxml internally
  stores strings in UTF-8.  The exceptions to this rule are the #to_s methods
  which return UTF-8 by default but can return other encodings if requested.

== 2.1.2 / 2011-08-03 Charlie Savage

* Fix segmentation fault that could occur when an XPathContext was marked
  before it was fully initialized (Charlie Savage).

* Add mark method to document to mark all nodes currently being accessed
  by ruby.  This make Ruby Enterprise Edition happy (Charlie Savage).

== 2.1.1 / 2011-07-31 Charlie Savage

* Switch to using def files to control library exports (Charlie Savage).

== 2.1.0 / 2011-07-31 Charlie Savage

* Ruby 1.9.3 compatability (Charlie Savage).

* Added XPath expression <-> Ruby value conversion methods (Jens Wille).

* Extracted rxml_xpath_to_value from rxml_xpath_context_find (Jens Wille).

* Adapted rxml_xpath_from_value from Gregoire Lejeune's ruby-xslt
  library, see https://github.com/glejeune/ruby-xslt (Jens Wille).

* Allow calling #find on nodes returned from Reader (Charlie Savage).

* Change document handling in XPath::Context to address segmentation fault on
  Ruby Enterprise Edition (Charlie Savage).

* Update gemspec file to work directly with bundler thereby allowing git
  repository to be used as gem (Charlie Savage).

* Support gem buld (Charlie Savage).

* Simplify memory management of attributes namespaces to fix
  segmentation faults that occurred when using Ruby 1.9.3 (Charlie Savage).


== 2.0.8 / 2011-06-23 Charlie Savage

* Add in 2 new HTML Parser constants - NODEFDTD and NOIMPLIED.

* Fix compile issue on Ruby 1.9.3

== 2.0.6 / 2011-05-23 Charlie Savage

* Fix segfault that sometimes occurred when looking up encodings on 1.9.
  In some cases the Ruby encoding infrastructure was not properly
  initialized (nkriege).

== 2.0.5 / 2011-05-05 Charlie Savage

* Document#validate_dtd would sometimes cause segmentation faults due to
  an improperly initialized data structure (Charlie Savage)

== 2.0.4 / 2011-05-02 Charlie Savage

* Fix compile issues on platforms using older versions of libxml2.  
  The problem as using a C14N constants that was added to libxml2
  in July 2009 (Charlie Savage).

== 2.0.3 / 2011-05-01 Charlie Savage

* The biggest change in this release is supporting the use of libxml-ruby in
  native background Ruby threads.  Previously, the use of libxml-ruby in
  background threads in Ruby 1.9.x and higher would often cause
  segmentation faults.  This has now been fixed (Charlie Savage).

* Update Reader#expand so that returned node correctly remembers its
  encoding in Ruby 1.9.x (zerebubuth).

* Add check to verify a node has not been deleted.  This can happen when
  a ruby variable holds a reference to a child node that gets freed
  when its parent gets freed.  Previously when this happened a
  segmentation fault would occur, now an exception is raised (Charlie Savage, fixes
  RubyForge #26839.

* Do not unlink nodes before internal validations have run - avoids
  segmentation faults caused by freeing a node twice (Charlie Savage).

* Add support for Document#canonicalization (Victor Lin).

* Updated documentation in README (Anurag Priyam):
1. rake doc does not work; use rake rdoc.
2. gem mislav-hanna does not exist; use hanna.
3. rake rdoc 'depends' on hanna; no need of RDOCOPTS
4. Point to the github issue tracker instead of Ruby Forge
5. Point to the github (gh-pages) site for docs

* Add tc_error to test suite (Charlie Savage).

* Add sax test (Stanislav O.Pogrebnyak).

== 2.0.2 / 2011-04-17 Charlie Savage

* Added binaries for windows (Charlie Savage).

* Update Ruby 1.9 encoding handling to support libxml versions older than
  version 2.6.26 which was released on June 6, 2006 (Charlie Savage).

* Add publish_with_docs rake task - combines publishing the
  website and docs (Anurag Priyam).

* Correctly copy the documentation directory (Anurag Priyam)

* Use relative link for rdoc so the links are correct on
  both rubyforge and github (Anurag Priyam).

* Update Rakefile to use Hanna RDco template (Charlie Savage).

* Update dates on license file (Charlie Savage).

* Add api to allow setting of attribute namespaces.  Fixes issue #10 (Charlie Savage).

* Remove old hack to call the on_error method.  This hack isn't needed anymore
  since a better workaround was put in place in the parser context. Fixes
  This fixes issue #12  (Charlie Savage).

* Remove references to passing blocks to validation functions.  The blocks are no
  longer called since the bindings use libxml's structured error handling.  See
  issue #6 (Charlie Savage).

* Fix up comment in Document and Node.  See issue #8 (Charlie Savage).

* Update website text (Charlie Savage).

== 2.0.0 / 2011-04-16 Charlie Savage

* Ruby 1.9.2 support.  The biggest addition is encoding support.
  Strings returned by the libxml bindings are now set to the encoding
  of the underlying xml document (Charlie Savage).

* Rubinius compatability. Removed unnecessary use of RHASH_TBL (Aman Gupta)

* Added .gemspec file (Dudley Flanders).

* Updated Windows checks to take into account mingw32 (Yaohan Chen).

* Fix memory leak in Reader#Expand (Szymon Nowak).

* Fix memory leaks in Reader#read_string, Reader#read_inner_xml
  and Reader#read_outer_xml (Sean Geoghegan).

* Node#space_preserve= was backwards (Dudley Flanders)

* Fixed typo in readme, added rdoc extension (Loren Sands-Ramshaw).

* Switched to Rake Compiler (Charlie Savage).

* Use xmlMalloc() memory for ctxt->sax structure.  Sometimes the ctxt->sax pointer
  may not be zeroed in rxml_sax_parser_parse(), for example when exception is raised
  in one of callbacks.  This lets xmlFreeParserCtxt() clean this up (Alexey I. Froloff).

* Added a rake task to publish the website to github. Moved the jekyll website to
  web directory (Anurag Priyam).

* Modernize project metadata and layout (7rans)


== 1.1.3 / 2009-03-18 Charlie Savage

* Improve performance 10 to 20% by turning on libxml2's dictionary
  feature that allows parsers to reuse previously parsed strings.

* Fix XML::Node#remove! to work correctly with libxml's dictionary feature.

* Correctly set up parser context options.

* Simplify DOM modification code (Node#next=, Node#prev=, Node#sibling=) and
  update documentation.

* Deprecated Node#add_child and Node#child=, use Node#<< instead

* Fix documentation for Node#<<

* Added Document#import to enable moving nodes from one document
  to another document.


== 1.1.2 / 2009-03-12 Charlie Savage

* Added XML::Node#inner_xml helper method.

* Fix segmentation that could occur when calling the mark function on a
  previously freed node.

== 1.1.1 / 2009-03-10 Charlie Savage

* Fix - Only include extra html parser context methods for versions of libxml
  older than 2.6.27.

== 1.1.0 / 2009-03-09 Charlie Savage

* Fix bug caused by the mark function being called on partially initialized
  attributes.

* Revert back to libxml2's internal memory manager.

== 1.0.0 / 2009-03-05 Charlie Savage

* OS X (Charlie Savage).  Update bindings to support the default installed
  version of libxml2 (2.6.16) on OS X 10.5 and the latest version available
  via MacPorts.

== 0.9.9 / 2009-03-05 Charlie Savage

* Ruby 1.9.1 support (Charlie Savage). libxml-ruby now compiles and runs on either
  1.8.6 and 1.9.1.  With 1.8.6 all tests should pass while on 1.9.1 all but
  for encoding tests pass.  The port to Ruby 1.9.1 revealed two memory
  allocation bugs (one with dtds, one with nodes) which are now fixed.

* Better OS X support (Joe Khoobyar).  The default version of libxml2
  on OS X 10.5 is fairly old, resulting in this link error:

    NSLinkModule() error
    dyld: Symbol not found: _htmlNewParserCtxt

  This can be fixed by using MacPorts to get a newer version of libxml2.
  To make use of MacPorts, the build script has been updated to use xml2-config.
  This can be fine-tuned using the new --with-xml2-config / --without-xml2-config
  options to extconf.rb (default is  --without-xml2-config to match existing behavior).

* Greatly reduced memory usage (Joe Khoobyar).
  See http://rubyforge.org/pipermail/libxml-devel/2009-February/001375.html.

* Add Document#xhtml? and document#node_type methods (Joe Khoobyar)

* Add XPath::Object#last (Joe Khoobyar)

* Provide finer control over CDATA nodes on a parser by parser basis  (Joe Khoobyar).

* Bug fix - Namespaces were incorrectly merged with attributes in the new sax2
  handler (Charlie Savage).

* Bug fix - Support iterating over nodes and attributes even with blocks
  that call remove! (Charlie Savage)

* Bug fix - If reader.node is NULL, return nil instead of crashing (Charlie Savage)

* Bug fix - Dtd's owned by documents were freed twice in some circumstances (Joe Khoobyar).

* Bug fix - Fix output escaping on attributes nodes (Joe Khoobyar).

* Bug fix - Make sure IO objects are not garbage collected when used
  as parser sources (Charlie Savage).

== 0.9.8 / 2009-1-24 Charlie Savage

* Refactored XML::Parser, XML::HTMLParser, XML::SaxParser and
  XML::Reader to have consistent APIs.  All the parsers
  now take a context object in their constructors, allowing fine
  grained control over the parsers for advanced use cases.  These
  API changes are backwards compatible except
  for XML::Reader, which now takes an optional hash table as a
  second parameter in its various constructors versus an optional
  boolean value.

* Updated all APIs to use the encoding constants defined
  in XML::Encoding versus string values.  This API change
  is not backwards compatible.

* Added support for attribute declarations in DTD's via the new
  XML::AttrDecl class (Len Lattanzi)

* Support libxml's content escaping capabilities for text nodes by
  wrapping libxml's "xmlStringText" and "xmlStringTextNoenc"
  (Joe Khoobyar).

* Updated XML::Reader#read API to return true if a node was read,
  false if node was not read and raises an exception on an error.
  Previously #read returned 1 if a node was read, 0 if a node was
  not read and -1 for an error.  This change is not backwards
  compatible, but provides a more natural interface for Ruby by
  allowing code like this:

  while reader.read
    # do stuff
  end

* Changed XML::Error exception objects to return copies of nodes that
  cause parse errors instead of the original node.  This prevents
  segmentation faults when the error is reraised.

* Added XML::Reader#node method.

* Fixed compile errors on OS X which uses an older version of libxml.

* Fixed memory leak when performing XPath searches.

* Fixed rdocs.

* Don't override libxml's default settings for entity substitution and
  loading external DTDs.  This may break some code - you may need to
  add in a call to XML.default_substitute_entities = true or
  XML.default_load_external_dtd = true.


== 0.9.7 / 2008-12-08 Charlie Savage

* Added SAX2 support.  SAX handlers now define two new callbacks,
  on_start_element_ns and on_end_element_ns methods.  These
  new callbacks support namespaces, making them superior to the older
  callbacks on_start_element and on_end_element methods.  The old callbacks
  are still supported, but may be deprecated in the future depending
  on community feedback.

* Added SAX support for libxml's structured error handling.
  That menas sax handlers now define a new callback, on_error,
  which takes one parameter, an instance of XML::Error.  The older
  on_parser_error, on_parser_warning and on_parser_fatal_error
  callbacks are no longer suported so you must port your code.
  Note that the older callbacks took one string parameter, instead of
  an XML::Error object.

* Experimental work-around for libxml error handling bug - see
  http://mail.gnome.org/archives/xml/2008-December/msg00014.html
  for more information.

* Fix compilation bugs on Solaris.

* Fix Rdoc compilation bug.


== 0.9.6 / 2008-12-08 Charlie Savage

* Refactored namespace handling.  The existing, and inconsistent,
  namespace methods defined on XML::Node have been deprecated.  
  They have been replaced by a the new XML::Namespaces class.
  Use this class to inspect a node's namespace, its default
  namespace, its namespace definitions and which namespaces
  are in scope.  It can be accessed via the the
  XML::Node#namespaces method.

* Rationalized XML::Document#save, XML::Document#to_s and
  XML::Node#to_s to take an optional hash table of parameters 
  that control how output is generated. Supported parameters
  include setting indentation on or off, the indentation level
  and the output encoding.  This is an API change and may break
  existing calls to XML::Document#save.  However, the previous
  API was broken - setting the encoding resulted in an error so
  its unlikely anyone is using it.

* Rationalized XML::Document#debug, XML::Node#debug, XML::XPath::XPathObject#Debug.

* Deprecated a number of duplicate dump* and debug_* methods in
  XML::Document and XML::Node.

* Additional Ruby 1.9.1 compatability fixes.

* Cleaned up header file guards.

== 0.9.5 / 2008-11-29 Charlie Savage

* Ruby 1.9.1 preview release compatability (Felipe Contreras)

* Update Node#remove! to return the removed node and to set
  its document to nil.  This allows the node to be either
  moved to another document, another part of the same document
  or to be freed on the next garbage collection once its
  references have gone out of scope.

* Fix bug where XPathExpression#compile mistakenly overwrote
  RegExp#compile.

* Update Node to use standard ruby allocators and initializers.

* Update HTML parser to be more forgiving of invalid documents.

* Update include paths for Darwin Ports on OS X.

* Updated C code base to use BSD/Allman style


== 0.9.4 / 2008-11-24 Charlie Savage

* Update HTML parser so that it can read files, strings and io
  streams.

* Update HTML parser to support user specified encodings.

* Additional C code cleanup.

== 0.9.3 / 2008-11-22 Charlie Savage

* Fixed segmentation fault caused by documents being freed
  before xpath results that referenced the document (take 2).

* Allowed sax parser to use io stream

* Combined encoding and input classes

* Cleaned up C code - removed remaining legacy structures,
  added static to most methods, changed C namespace from ruby_xml
  to rxml

== 0.9.2 / 2008-11-19 Charlie Savage

* Add support for compiled XPath expressions (donated by Pavel Valodzka)

* Fixes for compiling on OS X 10.5.4 and 10.5.5

== 0.9.1 / 2008-11-18 Charlie Savage

* Expose LibXML's encoding support via a new Encoding object.

* Revamp error handling to be much easier to use.  Errors are now
  wrapped by the new XML::Error class and are thrown as exceptions
  when it is appropriate.

* Fixed segmentation fault caused by documents being freed
  before xpath results that referenced the document.

* Add Node#register_default_namespace to simplify default namespace handling.

* Significantly improve documentation

* A number of bug fixes and patches.

== 0.9.0 / 2008-11-18 Charlie Savage

* Version 0.9.0 was removed due to packaging errors.


== 0.8.3 / 2008-07-21 Charlie Savage

* Missed several files in last release

== 0.8.2 / 2008-07-21 Charlie Savage

* To use LibXML you can either require 'xml' or require 'libxml'. 
  The differences is that require 'xml' mixes the LibXML module into
  the global namespace, thereby allowing you to write code such
  as document = XML::Document.new.  Note that this is different 
  from 0.8.0 and 0.8.1 and may require updating your code.

* Support RelaxNG validation (thanks to Morus Walter)

* Support passing IO objects to XmlReaders (thanks to Tom Hughes)

* Fix segmentation fault caused by adding an attribute to a CDATA node

* Moved node checking functions from C to Ruby

* Improved Windows support - libxml-ruby should now work out of the box.

* Improved Windows support - turned on libxml's zlib and iconv support.


== 0.8.1 / 2008-07-09 Charlie Savage

* Reimplmented Node#each_attr for backwards compatability

* Moved node type test to Ruby.


== 0.8.0 / 2008-07-09 Charlie Savage

* Fixed bug in returning attributes from XPath results

* Fixed DOM traversal methods

* Changed Node#children to return an array of nodes

* Fixed bug in returning attributes from XPath results

* Refactored XPath support, providing more user hooks in the XPath::Context class

* Added Node#properties for backwards compatibility

* Updated setup.rb

* Added more tests

* Updated rdocs and README file

* Moved libxml into LibXML namespace


== 0.7.0 / 2008-07-09 Charlie Savage

* Added new attributes class to provide a more natural way of working with attributes

* Fixed XML::Attr to better support namespaces

* Added documentation on how to use namespaces with XPath

* Removed allocation of extraneous structures used to wrap nodes, namespaces and attributes

* Cleaned up tests and added new test suite

* Updated rdocs and README file

* Cleaned out most of the bug list


== 0.6.0 / 2008-07-01 Charlie Savage

* Fixed memory allocation errors in Windows.  On Windows, it is essential that the same library that allocates memory must free it. Thus ALLOC calls must be matched to ruby_xfree calls, which they were not.  In addition, in one case Ruby was allocating memory to be freed by libxml.  On Windows, that's a segmentation fault.  On Linux it might fly, but still seems like a bad idea.

* Fixed segmentation fault in xml reader expand (same xml tree freed twice)

* Applied a number of patches from Tom Bagby, including fixes for xpath segmentation faults and fixes for various memory leaks

* Cleaned up a number of compiler warnings

* Renamed libxml_so.so to libxml_ruby.so (same for xslt).  That wasn't actually my original intention, but um, it kind of sort of happened.  It should not be noticeable from an end-user perspective.

* Added rake files for building with MingW

* Added rake files for packing gems.  Note that I did this outside the existing rake tasks because I didn't see how they were actually building the gems.

* Cleaned up the tests and added a few more based on bug reports from the Tracker and mailing list.

* Cleaned out the patch queue and went through about 1/2 the bug list
