mono/mcs/class/System.XML/System.Xml.XPath/ChangeLog

2004-11-24  Atsushi Enomoto  <[email protected]>

	* XPathEditableNavigator.cs, XPathChangeNavigator.cs,
	  IXPathEditable.cs : more removal of oldies.

2004-11-24  Atsushi Enomoto  <[email protected]>

	* NodeChangedEventArgs.cs, NodeChangedEventHandler.cs : removed oldies.

2004-11-08  Atsushi Enomoto  <[email protected]>

	* Tokenizer.cs : just use raw string instead of char[].
	* XPathNavigator.cs : reuse NameTable when creating XmlTextReader.

2004-11-07  Atsushi Enomoto  <[email protected]>

	* Iterator.cs :
	  - Made copy constructor certainly different from other constructors.
	  - Position is never computed in each derived type. All MoveNext() are
	    now MoveNextCore().
	  - Most of the protected members could just be private.

2004-11-05  Atsushi Enomoto  <[email protected]>

	* Expression.cs, XPathNavigator.cs : hold raw expression field for
	  get_Expression. It is preparation for expression optimization.

2004-11-05  Atsushi Enomoto  <[email protected]>

	* Iterator.cs : SimpleIterator._current could be cloned only when
	  it is required.

2004-11-05  Atsushi Enomoto  <[email protected]>

	* Iterator.cs : Some removal of Clone() were harmless.

2004-10-22  Atsushi Enomoto  <[email protected]>

	* XPathDocument.cs : now all the new stuff that used to be in 2.0 are
	  reverted.
	* XPathEditableNavigator.cs : It will be removed. Right now modified
	  a bit to pass build.
	* XPathNavigator.cs : Added members that are merged from
	  XPathEditableNavigator. Updated members name.

2004-10-14  Atsushi Enomoto  <[email protected]>

	* Iterator.cs :
	  - Added WrapperIterator to return BaseIterator in such case that 
	    variable reference is resolved to XPathNodeIterator. This fixes
	    bug #68267.
	  - Path ".." is reverse axis (actually no effect).
	  - Fixed DescendantIterator.Clone() that missed "_finished" field.
	* Expression.cs :
	  In ExprVariable.Evaluate(), use WrapperIterator() for custom
	  XPathNodeIterator.

2004-10-09  Atsushi Enomoto  <[email protected]>

	* XPathAtomicValue.cs : Init(string, XmlSchemaType) is private.

2004-10-05  Atsushi Enomoto  <[email protected]>

	* XPathAtomicValue.cs : missing Init() definition for float and string;
	  latter one resulted in infinite loop in Init(object,XmlSchemaType).

2004-10-04  Atsushi Enomoto  <[email protected]>

	* XPathNavigator.cs : TypedValue could be implemented.
	* XPathEditableNavigator.cs : removed some MonoTODO since now there 
	  are implementations.

2004-09-13  Atsushi Enomoto  <[email protected]>

	* XPathAtomicValue.cs : All .ctor() are separeted from Init().
	  In .ctor(object, XmlSchemaType):
	  - For lists that contains just one item, Init() recursively.
	  - For XPathAtomicValue, Init() recursively for its content fields.
	  For Value and TypedValue, consider typecode from XmlSchemaType.

2004-09-06  Atsushi Enomoto  <[email protected]>

	* XPathEditableNavigator.cs :
	  AppendChild(xmlReader) ignored nodes after than first one, and
	  resulted in infinite loop.
	  Added get_OuterXml overrides. set_OuterXml should not move to
	  parent before deleting current.

2004-08-25  Atsushi Enomoto  <[email protected]>

	* XPathAtomicValue.cs : Value was not returning expected value when
	  it is created as new XPathAtomicValue (object, XmlSchemaType).
	  Compute stringValue and reuse.
	* XPathNavigator.cs : Temporarily stubbed as to ignore SchemaInfo
	  (for checking XQuery implementation).

2004-08-25  Atsushi Enomoto  <[email protected]>

	* XPathAtomicValue.cs : Handle .ctor() with object parameter more
	  precisely (still not enough, for list argument).
	  Removed commended blocks.

2004-08-24  Atsushi Enomoto  <[email protected]>

	* XPathAtomicValue.cs : DateTime should be convertible to string.
	  Use schemaType's TypeCode for .ctor() that takes object.
	* XPathNavigator.cs : copied get_InnerXml from XPathEditableNavigator.
	* XPathEditableNavigator.cs : set_InnerXml should be different (new)
	  property from get_InnerXml. Removed get_InnerXml and get_OuterXml 
	  overrides.

2004-08-23  Atsushi Enomoto  <[email protected]>

	* XPathAtomicValue.cs, XPathNavigator.cs : Eliminate MS.Internal.Xml.*.

2004-08-03  Atsushi Enomoto  <[email protected]>

	* XPathEditableNavigator.cs : implemented some editor support methods.

2004-08-02  Atsushi Enomoto  <[email protected]>

	* XPathDocument.cs :
	  - For .NET 2.0, added a switch to support new XPathDocument2. 
	    If switch is off, then it uses DTM.
	  - Implemented remaining 2.0 bits (except for Obsolete ones).

	To use them in XPathDocument, set environment MONO_XPATH_DOCUMENT_2=yes
	(It is still too unstable to pass all nunit tests and standalone XSLT
	tests).

2004-07-29  Atsushi Enomoto  <[email protected]>

	* XPathNavigator.cs : Implemented ReadSubtree().

2004-07-28  Atsushi Enomoto  <[email protected]>

	* XPathDocument.cs : for .ctor() and .ctor(XmlNameTable), now it 
	  creates Mono.Xml.XPath.XPathEditableDocument and thus supports
	  IXPathEditable.CreateEditor().

2004-07-28  Atsushi Enomoto  <[email protected]>

	* XPathEditableNavigator.cs : Implemented InsertAfter() and 
	  PrependChild(); they are virtual, not abstract.
	* XPathNavigator.cs :
	  Implemented many 2.0 virtual properties and methods that were 
	  abstract in 1.x.
	  Implemented some Select() methods that uses IXmlNamespaceResolver.
	  Implemented most of ValueAsXxx() using XQueryConvert.
	  IsNode is always true. Implemented OuterXml and WriteSubtree() (but
	  actually they don't work because it depends on ReadSubtree()).

2004-07-26  Atsushi Enomoto  <[email protected]>

	* XPathDocument.cs : added missing && not-likely-to-be-removed members.
	* XPathEditableNavigator.cs : added BuildSubTree().
	* XPathException.cs : added missing methods. Hide Message in NET_2_0.

2004-07-23  Atsushi Enomoto  <[email protected]>

	* XPathNodeIterator.cs : implemented 2.0 GetEnumerator().

2004-07-21  Atsushi Enomoto  <[email protected]>

	* XPathExpression.cs, Expression.cs :
	  Added SetContext(IXmlNamespaceResolver).
	* NodeChangedEventArgs.cs : Added missing [MonoTODO].
	* XPathAtomicValue.cs : Halfly implemented.
	* XPathDocument.cs : Added 2.0 members.
	* XPathDocumentNodeChangedAction.cs : updated member names.
	* XPathEditableNavigator.cs : Added missing 2.0 members and MonoTODO.
	* XPathNavigator.cs : Added missing 2.0 members.
	  Fixed some members as virtual->override.

2004-07-13  Atsushi Enomoto  <[email protected]>

	* XmlNodeChageType.cs, XmlChangeFilters.cs : fixed enum values.
	* XPathResultType.cs : marked [MonoFIX] on .Navigator.

2004-07-11  Atsushi Enomoto  <[email protected]>

	* Expression.cs, Iterator.cs, XPathNavigator.cs :
	  Use IXmlNamespaceResolver for net 2.0. Removed unused code.
	* XPathEditableNavigator.cs : fixed namespace.
	* XPathNavigator.cs :
	  Fixed inheritance. Added missing MonoTODO.
	  Removed old .net 1.2 code. 

2004-06-18  Atsushi Enomoto  <[email protected]>

	* DefaultContext.cs : Globalization.
	* Iterator.cs : In SlashIterator.MoveNext() position might keep 0
	  in case of empty list. Thus extraneous iteration might happened.
	  Removed unused (and clone unsafe) EnumeratorIterator.

2004-06-06  Atsushi Enomoto  <[email protected]>

	* XPathDocument.s : The previous patch is still incomplete to close.

2004-06-05  Atsushi Enomoto  <[email protected]>

	* XPathDocument.cs : close self-opened XmlTextReader in .ctor().

2004-06-03  Atsushi Enomoto  <[email protected]>

	* Expression.cs : LookupNamespace() only allows already-atomized names.
	* XPathEditableNavigator.cs : removed incorrect set_OuterXml() and 
	  set_InnerXml().

2004-05-22  Atsushi Enomoto  <[email protected]>

	* DefaultContext.cs : Add XPathNavigator input support for ToBoolean()
	  and ToNavigator().
	* Expression.cs : In Equality comparison, evaluate XPathNavigator in
	  the same as well as NodeSet. This fixes bug #59134.

2004-05-22  Atsushi Enomoto  <[email protected]>

	* XPathAtomicValue.cs : missed NET_2_0.

2004-05-22  Atsushi Enomoto  <[email protected]>

	* IXPathChangeNavigable.cs,
	  IXPathEditable.cs,
	  NodeChangedEventArgs.cs,
	  NodeChangedEventHandler.cs,
	  XPathAtomicValue.cs,
	  XPathChangeNavigator.cs,
	  XPathDocumentNodeChangedAction.cs,
	  XPathEditableNavigator.cs,
	  XPathItem.cs,
	  XmlChangeFilters.cs,
	  XmlNodeChangeType.cs : added NET_2_0 classes.
	* XPathDocument.cs,
	  XPathNavigator.cs : updated NET_2_0 members.

2004-05-20  Atsushi Enomoto  <[email protected]>

	* Expression.cs : We should not catch all kind of exception. Just
	  throwing any kind of exception would be preferable.
	  Added support for XPathNavigator values.

2004-05-13  Atsushi Enomoto  <[email protected]>

	* DefaultContext.cs : Removed MonoTODO. done.
	* Expression.cs : handle XPathResultType.Navigator in some places and
	  removed MonoTODO. Mark MonoTODO with explicit comments (though they
	  are mostly pointing out possibilities of optimization).
	  Removed extra check that depended on the old bugs.
	* XPathResultType.cs : Fixed .Navigator that had the same value as
	  .String.

2004-05-12  Atsushi Enomoto  <[email protected]>

	* Parser.jay : made class internal.

2004-03-16  Atsushi Enomoto  <[email protected]>

	* XPathNavigator.cs, Iterator.cs : Considered detached nodes, the 
	  result of MoveToParent() should be checked.

2004-02-17  Atsushi Enomoto  <[email protected]>

	* XPathNavigator.cs : Only child and attribute axes are allowed for
	  Matches().
	* Expression.cs : Added IsPositional property.
	* DefaultContext.cs : Added some overrides.

2004-02-16  Atsushi Enomoto  <[email protected]>

	* XPathNavigator.cs : no, its still not ok. comment out now.

2004-02-16  Atsushi Enomoto  <[email protected]>

	* Expression.cs : Added EvaluatedNodeType and NeedAbsoluteMatching
	  to reduce extraneous Matches() trial.
	* Iterator.cs : Removed unused MergedIterator.
	* XPathNavigator.cs : Optimized Matches() not to evaluate ancestors
	  unnecessarily. (Test with NeedAbsoluteMatching).

2004-02-10  Atsushi Enomoto  <[email protected]>

	* Iterator.cs : Added overriden Count properties for some iterators
	  (this fixes the half of #50678).
	  Added ListIterator class (which can reduce GetEnumerator()). 
	  In some places we can omit clone for Current property, so added 
	  some check logic (It has no effect as yet).
	* Expression.cs, DefaultContext.cs :
	  use ListIterator instead of EnumeratorIterator.

2004-02-08  Atsushi Enomoto  <[email protected]>

	* DefaultContext.cs, Expression.cs, Iterator.cs :
	  tiny foreach elimination.

2004-02-05  Atsushi Enomoto  <[email protected]>

	* DefaultContext.cs : trivial processing order fix.

2004-01-27  Atsushi Enomoto  <[email protected]>

	* DefaultContext.cs : Avoid exception if possible.
	* Iterator.cs : Fixed PrecedingSiblingIterator.MoveNext(). When the
	  nav was positioned at the first, it incorrectly points itself.
	  Don't add names to name table while it is useless and expensive.

2004-01-08  Nick Drochak <[email protected]>

	* Iterator.cs: Removed unused variable.
	
2003-12-18 Atsushi Enomoto  <[email protected]>

	* Parser.jay : now it supresses error output from jay.
	* DefaultContext.cs : (XPathFunctionSubstring) exclude -Infinity.
	* Tokenizer.cs : better error message.
	* XPathDocument.cs : Use XmlValidatingReader to support id() function.
	  (just found MS.NET actually supports it)

2003-12-16 Atsushi Enomoto  <[email protected]>

	* Iterator.cs : On its iteration, moving Current must not affect to
	  MoveNext(). To assure this, Current must be a clone of navigator.
	  Removed unused code.

2003-12-07 Atsushi Enomoto  <[email protected]>

	* Tokenizer.cs : Removed some TODOs. (trivial ;-)
	* Iterator.cs : ParensIterator can inherit from BaseIterator.
	  SlashIterator copy .ctor() always failed to clone. This fixes Count.

2003-12-03 Atsushi Enomoto  <[email protected]>

	* Expression.cs : XPathSorters.Compare() should compare document
	  position. See last sentence of XSLT 1.0 secion 10.

2003-12-03 Atsushi Enomoto  <[email protected]>

	* DefaultContext.cs : Overrode all functions' ToString().
	  XPathFunctions.ToNumber() trims whitespaces at both side.
	  Fixed NullReferenceException in normalize-space().
	* Iterator.cs : Fixed AncestorOrSelfIterator.MoveNext() didn't handle
	  attribute or namespace node correctly.
	  SlashIterator.Clone() didn't clone "next node iterator" correctly.
	  EnumeratorIterator.ctor() should raise an error (not at Clone())
	  when the target IEnumerator is not ICloneable.

2003-11-28  Atsushi Enomoto  <[email protected]>

	* Expression.cs : namespace axis now traversed in reverse order, so it
	  requires sorting.
	* Iterator.cs : UnionIterator.Clone() was incomplete. 
	  NamespaceItarator() should be reverse order (special handling
	  because of XPathNavigator specification).

2003-11-24  Atsushi Enomoto  <[email protected]>

	* Iterator.cs : PrecedingIterator.MoveNext() now breaks up at Root.
	* XPathNavigator.cs : ComparePosition() didn't handle attributes 
	  correctly.

2003-11-24  Atsushi Enomoto  <[email protected]>

	* Parser.jay, Expression.cs, Iterator.cs :
	  Added ExprParens and ParensIterator classes which is used to handle
	  precedence of parenthesized expressions.
	  (e.g. consider "(preceding::*)[3]" and "preceding::[3]" )

	* Expression.cs, Iterator.cs :
	  Added RequireSorting property for each Expr and BaseIterator classes.
	  SlashIterator.MoveNext() now considers correct sorting. But
	  considering performance, it separates two logics, sorted and sortless
	  depending on RequireSorting of left iterator and right expression.

	* Iterator.cs :
	  SimpleIterator.ctor() should consider when nav is null.
	  FollowingIterator.MoveNext() and PrecedingIterator.MoveNext() should
	  not return any nodes.
	  AncestorIterator and AncestorOrSelfIterator copy ctr() should clone
	  positions.
	  AncestorIterator.MoveNext() should skip Root if context node is
	  Root itself.
	  FollowingIterator.MoveNext() should not handle children of context
	  itself.
	  PrecedingIterator.MoveNext() should skip its ancestors.
	  AxisIterator.ReverseAxis should be dependent on its containing iter.
	  UnionIterator.MoveNext() should consider comparison of nodes in 
	  different document. The behavior is implementation dependent.
	  (see XSLT spec 12.1)

2003-11-19  Atsushi Enomoto  <[email protected]>

	* Added XPathComparer.cs
	* DefaultContext.cs : Fixed XPathFunctionId.Evaluate() to iterate base 
	  iterator correctly, and sort results.

2003-11-19  Atsushi Enomoto  <[email protected]>

	* DefaultContext.cs : Imcomplete fix ;-)

2003-11-19  Atsushi Enomoto  <[email protected]>

	* DefaultContext.cs : XPathFunctions.ToNumber() should catch overflow.
	  XPathFunctionId.cs : Exposed Id expression.
	* Expression.cs : Added ExprLiteral.Value, and class ExprParens (it
	  will be used to solve evaluation precedence problem).

2003-11-09  Atsushi Enomoto  <[email protected]>

	* Iterator.cs : Fixed SlashIterator that might return nodes 1)in
	  inconsistent order, and 2)may return duplicate result nodes.

2003-11-06 Ben Maurer  <[email protected]>

	* Iterator.cs: (AxisIterator.ComparablePosition): Remove. Let
	it inherit from the base class. This made b[2] evaluated on 
	<a /><b /><c /><a /><b /><c /> return the first b node because
	in the ChildIterator it was the second node and seemed to satsify
	the predicate.

2003-11-04  Atsushi Enomoto  <[email protected]>

	* Iterator.cs : Added bool ReverseAxis property to identify whether
	  the iterator is in reverse order or not.  Added ComparablePosition
	  for correct position comparison for PredicateIterator and reverse-
	  order-axes.  Modified AncestorIterator, AncestorOrSelfIterator,
	  PrecedingIterator and PrecedingSiblingIterator to make MoveNext()
	  return their nodes in document order. This fixes bugzilla #39079.

2003-10-15  Atsushi Enomoto  <[email protected]>

	* Iterator.cs : DescendantIterator and FollowingIterator also should
	  not MoveNext() after they reached to the end.

2003-10-13  Atsushi Enomoto  <[email protected]>

	* Iterator.cs : Fixed UnionIterator who ignores document order.
	  Fixed SlashIterator whose MoveNext() should finish at its end.

2003-09-27 Ben Maurer  <[email protected]>

	* Iterator.cs, Expression.cs, XPathNavigator.cs: In AxisIterator
	use NameTable so we dont call strcmp.

2003-09-27 Ben Maurer  <[email protected]>

	* DefaultContext.cs (translate): translate ("abc", "c", "") = "ab"
	not "abc".
	* Iterator.cs, Expression.cs: All axes are
	SimpleIterators. SimpleIterators are gaurenteed to give the same
	XPathNavigator in Current. Make AxisIterator take a
	SimpleIterator, not any old BaseIterator. Will allow us to make
	NameTable optimizations and avoid quite a few strcmp's.

2003-09-24 Ben Maurer  <[email protected]>

	* Expression.cs: make // work right, must use another slash itr.

2003-09-21 Ben Maurer  <[email protected]>

	* Expression.cs: cant use $$ before assigned.

2003-09-21 Ben Maurer  <[email protected]>

	* Expression.cs, Parser.jay, XPathNavigator.cs: api beautification.

2003-09-20 Ben Maurer  <[email protected]>

	* Expression.cs: num != double.NaN does not work.

2003-09-19 Ben Maurer  <[email protected]>

	* Expression.cs: in NodeTypeTest dont throw an exception if it is
	an unknown node type (allows for better Pattern debugging).

2003-09-17 Ben Maurer  <[email protected]>

	* DefaultContext.cs: implement sum () and translate ().

2003-09-13 Ben Maurer  <[email protected]>

	* XPathNavigator.cs: Make methods where you pass in the context,
	so that we dont have to clone expressions so much.

2003-09-06 Ben Maurer  <[email protected]>

	* DefaultContext.cs, Expresssion.cs, Parser.jay: Rewrite so that
	system functions are actually expressions. Will allow for some
	nice optimizations.

2003-08-25 Ben Maurer  <[email protected]>

	* XPathNavigator.cs: "Smart" behavior in Matches. Nice 8x speed
	improvement in the method (5ms/call -> .7 ms / call) measured by
	monodoc's rendering of N:System.
	* Expression.cs: Utility methods to support above.

2003-08-13 Piers Haken	<[email protected]>
	
	* Iterator.cs:
		fix MergedIterator.Clone(), now clones other's iterators
		fix DescendantIterator.Clone(), now copies depth

	(Message): Added.

2003-07-29 Piers Haken	<[email protected]>

2002-04-12  Duncan Mak  <[email protected]>

	* XmlCaseOrder.cs: Moved to here from System.Xml.

2002-03-26  Jason Diamond  <[email protected]>

	* XPathScanner.cs: Now handles name tests with wildacards. Abbreviated 
	steps. Both absolution and relative abbreviated location paths.

2002-03-25  Jason Diamond  <[email protected]>

	* XPathScanner.cs: Added new file. This class is supposed to be internal
	but that would make it impossible to test.

2002-03-08  Duncan Mak  <[email protected]>

	* XPathNamespaceScope.cs:
	* XPathNodeType.cs:
	* XPathResultType.cs:
	* XmlDataType.cs:
