	  Fixed bug #74631.

2005-04-13  Atsushi Enomoto  <atsushi@ximian.com>

	* DataTable.cs : Use GetRowType() for the base of the returning array 
	  type of Select(). Fix by Gerhard Rittweger.
	* CustomDataClassGenerator.cs : Fixed slightly harmless wrong code.

2005-04-13  Atsushi Enomoto  <atsushi@ximian.com>

	* CustomDataClassGenerator.cs : custom relation was not added to
	  Relations property. The second entry of bug #69276 was fixed.
	  Patch by Daniel Rodriguez.

2005-04-07  Lluis Sanchez Gual <lluis@novell.com>

	* DataRowCollection.cs: Fix the signature of the Add method
	for NET_2_0.

2005-03-16  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRow.cs : on importing row, it was copying data from incorrect
	  DataRow. This fixes bug #73288.

2005-03-07  Jackson Harper  <jackson@ximian.com>

	* DataViewManagerListItemTypeDescriptor.cs: Implement missing
	features. These are needed for System.Windows.Forms databinding.

2005-02-25  Atsushi Enomoto  <atsushi@ximian.com>

	* DataColumn.cs : setting negative value on MaxLength of SimpleContent
	  column is still valid.

2005-02-15  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlSchemaWriter.cs : new file for outputting XmlSchema.
	* DataSet.cs : removed rewritten code in XmlSchemaWriter.
	* XmlConstants.cs : added UseCurrentCulture constant.
	* DataTable.cs :
	  Use new Xml Schema writer.
	  Use XmlSchemaDataImporter as we use in DataSet.

2005-02-10  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs, DataRowView.cs : Fixed bug #72421. CreateChildView()
	  should target only child rows.

2005-02-03  Atsushi Enomoto  <atsushi@ximian.com>

	* DataViewManager.cs: misuse of ReadStartElement(string).
	* DataRowView.cs : removed some MonoTODO.

2005-02-02  Sureshkumar T  <tsureshkumar@novell.com>
	    Ankit Jain     <radical@corewars.org>

	* DataColumn.cs: throw exception if the column is part of a
	relationship, when chaning the data type. Added methods
	"GetParentRelation ()" and "GetChildRelation ()" get the relation
	which contains the current column
	* DataRelation.cs: Added method "Contains (DataColumn)" to check
	whether the relation contains the given column.

	fixes nunit failure: DataRelationTest.InvalidConstraintException2.

2005-02-02  Sureshkumar T  <tsureshkumar@novell.com>

	* DataColumnCollection.cs: implemented todo item "check for
	constraints" when removing columns from table.
	* DataRowCollection.cs: Clear (): don't have to throw child key
	constraint exception when the child table does not have any
	rows. safe to remove parent rows.
	* UniqueConstraint.cs: added method "Contains (DataColumn)" to
	check whether a column is part of UniqueConstraint.
	* ForeignKeyConstraint.cs: added method "Contains (DataColumn,
	lookInParent)" to check whether a column is part of foreignkey.

	fixes nunit failure: DataTableTest.ClearTest ()

2005-02-02  Sureshkumar T  <tsureshkumar@novell.com>

	* ForeignKeyConstraint.cs: validating columns: move checking
	"tables are of same dataset" before "checking column types".

	fixes nunit failure: ForeignKeyConstraint.CtorExceptions.
	
2005-02-02  Atsushi Enomoto  <atsushi@ximian.com>

	* DataViewManager.cs : let's just use StringWriter instead of 
	  XmlTextWriter (to avoid empty tag string mismatch annoyance.)
	* DataView.cs : implemented BeginInit() and EndInit(). Don't update
	  rows during init phase until EndInit() is invoked. During init phase,
	  just hold properties such as Sort that affects on rows.

2005-02-02  Atsushi Enomoto  <atsushi@ximian.com>

	* DataTableCollection.cs : (RemoveAt) just use IndexOutOfRangeException.

2005-02-02  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs : DataRowView.EndEdit() raises ItemMoved event.
	  set_Table clears Sort and RowFilter.

2005-02-02  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs :
	  - Clear() should clear AddNew cache.
	  - Open() invokes Reset().
	  - ConstraintCollectionChanged() itself does not invoke OnListChanged().
	  - Reset() does not Open, Close and Update Index.
	  - UpdateIndex() can be invoked even if it has no table.
	  - Reset event is invoked always after actual query to table.
	  - set_Table should raise PropertyDescriptorChanged event.

2005-02-02  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs : ColumnCollectionChanged() is the event invoker (i.e.
	  when overriden, no column change events are fired).

2005-02-02  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs : CancelEditRowView() and DeleteRowView() was incorrectly
	  checking target tables. They also should raise events if required.

2005-02-02  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs : simplify code with UnsortedList.

2005-02-01  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs : Mostly reimplemented.
	  - UpdateIndex() is invoked only when it is required (results in 
	    significant performance improvement).
	  - Use SortedList and wrapper OptionalSortedList which switches
	    between SortedList (with Sort) and UnsortedList (without Sort).
	  - DataView itself now contains two collections for rowviews:
	    Table rows based pool and AddNew() based cache. Consider those
	    two collections in every members.
	  - Reset() does not clear rows. Just invokes UpdateIndex().
	  - Hook RowDeleting, ColumnChanging and ColumnChanged events in table
	    which is required to handle state changes.
	  - Reimplemented Find() and FindRows() because of internal changes.

2005-02-01  Atsushi Enomoto  <atsushi@ximian.com>

	* DataTable.cs : Fixed row comparer. Even if every of the sort target
	  columns are identical for two rows, they should not be regarded as
	  the same unless they are Object.ReferenceEquals.

2005-02-01  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRowCollection.cs : on adding a row, should raise
	  ChangingDataRow() as well as ChangedDataRow().

2005-01-31  Sureshkumar T  <tsureshkumar@novell.com>

	* DataRow.cs: SetParentRow (): use relation.ParentColumns &
	relation.ChildColumns instead of relation.ChildKeyConstraint.*
	because createConstrains flag may be false when creating data
	relations. Hack along with Ankit Jain.
	
2005-01-31  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs :some interface implementations.

2005-01-28  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs : Add to table only when the row is not in the table.

2005-01-28  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs : implemented FindRows() (btw we should not use
	  DataTable since there are detached rows by AddNew().)

2005-01-28  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs :
	  Code cleanup: privatify some members, remove unused methods.
	  Some event-based invocation methods should not raise NotImplemented.

2005-01-28  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : ReadXml() became closer to MS behavior, being hacky.

2005-01-28  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlSchemaDataImporter.cs : empty element is not regarded as a column.

2005-01-28  Atsushi Enomoto  <atsushi@ximian.com>

	* UniqueConstraint.cs : mostly reverted the previous patch + check
	  IsPrimaryKey before validation.

2005-01-28  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs : Fixed duplicate insertion to Hashtable.
	* UniqueConstraint.cs : Unique constrained pair of columns could be
	  nullable.

2005-01-27  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs :
	  Don't do anything for Sort/ApplyDefaultSort/RowFilter/RowStateFilter
	  when the same value is being set.
	  Examined UpdateIndex() and marked FIXME where MS does not invoke it.
	  Removed unused OnColumnChanged().
	  Now store rowViewPool and reuse DataRowView objects.
	  Optimized UpdateIndex() - avoid ArrayList. Avoid Haashtable.Rehash().

2005-01-27  Atsushi Enomoto  <atsushi@ximian.com>

	* DataViewSettings.cs : no MonoTODO anymore.
	* DataViewManager.cs : pass itself to new DataView() (new ctor).
	* DataRowView.cs : GetHashCode() returns its Row's hash.
	* DataTablePropertyDescriptor.cs : use new ctor().
	* DataView.cs : added new ctor()s that accept DataViewManager.

2005-01-27  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs, DataRowView.cs : AddNew() should not add the row to table
	  (it is still detached). So handle those rows differntly.
	  CancelEdit(), EndEdit() and Delete() propagates those events to
	  DataView (and handle row collection).
	  Eliminate "throw new Exception()".
	  Don't catch all the exception thrown in ListChanged event.
	* DataTable.cs : made RowSorter as internal and use it in DataView.
	  no need to pass DataRow[] to .ctor().

2005-01-27  Atsushi Enomoto  <atsushi@ximian.com>

	* DataTable.cs : don't create DefaultView unless it is required. It
	  significantly improves performance. (i.e. DataView perf. is sick ;-)

2005-01-27  Atsushi Enomoto  <atsushi@ximian.com>

	* DataViewSetting.cs,
	  DataViewSettingCollection.cs,
	  DataViewManager.cs : implemented basic members.

2005-01-26  Atsushi Enomoto  <atsushi@ximian.com>

	* Node.cs, DataColumnPropertyDescriptor.cs, DataTable.cs :
	  Eliminate "throw new Exception".

2005-01-25  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRow.cs : (set_Item) RowNotInTableExeption check should be done
	  regardless of index existence.

2005-01-25  Atsushi Enomoto  <atsushi@ximian.com>

	* DataTable.cs : use new IExpression.EvalBoolean() to avoid extraneous
	  boxing.

2005-01-25  Sureshkumar T  <tsureshkumar@novell.com>

	* DataTable.cs: ImportRow :Do not add to rows collection if the
	import row is in detached state.

2005-01-25  Sureshkumar T  <tsureshkumar@novell.com>

	* DataRow.cs: CopyValuesToRow : set the column value with the
	default version of the given row.
	* DataTable.cs: ImportRow: Copy values before adding row.
	* DataSet.cs: AddChangedRow: Add the row to the table after
	copying values.
	
	Fixes bug #67317. Patch by Ankit Jain.

2005-01-25  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRowView.cs : Fixed IsEdit to reflect correct status of DataRow.
	* DataRow.cs : Expose editing status internally.

2005-01-25  Atsushi Enomoto  <atsushi@ximian.com>

	* DataView.cs : missing attributes.

2005-01-24  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRowView.cs : implemented CreateChildView().

2005-01-24  Atsushi Enomoto  <atsushi@ximian.com>

	* DataTable.cs, DataView.cs :
	  Optimized DataView to compile only once RowFilter and Sort when 
	  those properties are set. To make it possible, extracted 
	  SortableColumn out of DataTable and added internal DataTable.Select()
	  that accepts precompiled IExpression and SortableColumns[].

2005-01-24  Atsushi Enomoto  <atsushi@ximian.com>

	* DataColumn.cs : set_MaxLength is not allowed when it is mapped to
	  SimpleContent. (However, it is weird but it never fails when we set
	  ColumnMapping = MappingType.SimpleContent when we fhave MaxLength.)

2005-01-21  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRow.cs : more Current -> Default fixes. Check if it should throw
	  VersionNotFoundException. Patch by Ankit Jain.

2005-01-21  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRow.cs : Default selects the right version for the current
	  state of the row. Current is not always available. Also change
	  that for GetParentRow(). Patch by Ankit Jain.

2005-01-21  Atsushi Enomoto  <atsushi@ximian.com>

	* DataTable.cs : CopyColumn() should copy AutoIncrement after
	  DefaultValue, or it will raise an error in some cases.

2005-01-20  Atsushi Enomoto  <atsushi@ximian.com>

	* ConstraintCollection.cs : Add() should throw ArgumentException when
	  the argument constraint fails validation.
	  DataTable.cs : set_PrimaryKey should throw ArgumentException when
	  the argument contains constraints which fail validation.

2005-01-19  Sureshkumar T  <tsureshkumar@novell.com>

	* DataRelationCollection.cs: 

	Method Remove : Donot throw exception if DataRelation argument is
	null in DataRelationCollection.Remove method.

	Method RemoveAt : Exception should be IndexOutOfRangeException if
	row index is not in list range.

	Fixes nunit failures DataRelationCollection.Remove and
	DataRelationCollection.RemoveAt.

2005-01-19  Sureshkumar T  <tsureshkumar@novell.com>	

	* ConstraintCollection.cs: Donot throw exception if constraints
	are null in AddRange method. Check for null before using the
	argument.

	fixes bug #69381.

2004-01-19  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataInferenceLoader.cs,
	  XmlDataReader.cs : Check if the XmlReader (node) represents DataSet
	  or a table, reusing code block in XmlDataInferenceLoader.
	  This fixes bug #60118.

2004-01-19  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDiffLoader.cs : Ankit Jain <radical@imt.ac.in> has a conflicting
	  patches and some good catches. Some attributes should be skipped,
	  and loaded value must be typed.

2004-01-19  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlConstants.cs,
	  XmlDataInferenceLoader.cs, 
	  XmlDataReader.cs : use common const for http://www.w3.org/2000/xmlns/.
	* XmlDiffLoader.cs : It was not handling attributes. Fixed bug #70961.

2005-01-18  Sureshkumar T  <tsureshkumar@novell.com>

	Fix for bug #66838. This patch is submitted by "Ankit Jain"
	<radical@corewars.org> and refactored.

	* DataRow.cs: Allows to set a parent row even if the row is in
	detached state.

	* DataRelation.cs: method "UpdateConstraints" is added to check
	and create missing keys when adding a relation. This is refactored
	approach from DataRelationCollection.Add method.

	* DataRelationCollection.cs: AddCore methods of all relation types
	are synchronized. A Check for existing constraints is
	done. Relation is added to the list only if all checks are passed.

2004-01-18  Atsushi Enomoto  <atsushi@ximian.com>

	* DataColumnCollection.cs : Clear() throws ArgumentException that
	  wraps thrown innerException.
	* XmlSchemaDataImporter.cs : removed FIXMEs.

2004-01-12  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : When serializing DataTable, BuildSchema() is passed
	  null relation collections.
	  Quick fix for XmlSerializer deserialization. It does not require
	  XML Schema included.

2004-01-11  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs,
	  CustomDataClassGenerator.cs :
	  In DataSet class, IXmlSerializable.GetSchema() returns null.
	  In strongly-typed class, it returns schema.

2004-01-07  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataInferenceLoader.cs : test driver class should be excluded.

2004-12-01  Miguel de Icaza  <miguel@ximian.com>

	* DataView.cs: Patch from Marc Haisenko that ensures that rowCache
	is never null.

2004-11-10  Atsushi Enomoto  <atsushi@ximian.com>

	* CustomDataClassGenerator.cs : generated foreign key constraint
	  construction code was creating empty child columns and thus it
	  was invalid. This fixes bug #69276 (patch by Martin Voelkle).

2004-11-02  Atsushi Enomoto  <atsushi@ximian.com>

	* CustomDataClassGenerator.cs : custom DataTable ctor should call
	  InitializeFields(), and those DataColumns created by that method
	  should take data type. This should fix bug #68972.

2004-10-15  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : Also clear UnhandledAttributes ArrayList before 
	  generating next attribute column schema. This fixes bug #68432.

2004-10-14 Umadevi S <sumadevi@novell.com>
        * DataTable.cs : Corrected the Clone method to use  Activator.CreateInstance so that the
        correct subclass is returned. This fixes bug #67631
                                                                                        
2004-10-14 Umadevi S <sumadevi@novell.com>
	* DataSet.cs : Corrected the Clone method to use  Activator.CreateInstance so that the 	
	correct subclass is returned. This fixes bug #67627

2004-10-13  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : clear UnhandledAttributes ArrayList before generating
	  next element column schema. This fixes bug #68256.

2004-10-12  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : now xs:schema contains xmlns="".
	  This fixes bug #68008.

2004-10-12  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : DBNull attribute column should not be written as
	  empty attribute. This fixes bug #68007.

2004-10-12  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs, XmlConstant.cs, XmlSchemaDataImporter.cs:
	  DataColumn.ReadOnly was not handled. This fixes bug #68005.
	  Attribute defaultValue was not handled too.

2004-10-07  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs :
	  - When AllowDBNull is false on attribute DataColumn, its schema
	    should contain use="required". This fixes bug #66792.
	  - If MaxLength is set on attribute DataColumn, the mapped schema
	    type should contain maxLength facet. This fixes bug #66793.

2004-10-04  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : For a row, when a relation is not nested, then it is
	  still output target since it won't be written as a child of its
	  parent. It fixes bug #66379.

2004-10-03  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : Attribute constraint field XPath must be written as
	  @blah. This fixes bug #66366.

2004-09-28 Umadevi S <sumadevi@novell.com>
	* DataRow.cs - checked for Enforceconstraints, while using indices to search for related rows

2004-09-24  Sureshkumar T  <tsureshkumar@novell.com>

	* DataSet.cs : Don't check constraints for dataset clear
	* DataRowCollection.cs : check for EnforceConstraints flag 
	before checking foriegn key constraints in Clear method
	* DataTable.cs : Redundant checking removed in Clear method as it is
	checked in DataRowCollection.Clear method. 


2004-09-19  Sureshkumar T <tsureshkumar@novell.com>
	* DataRow.cs : while deserialization of dataset, adding a current row precedes the original row.
		       hence, adding a row cache is necessary if the original row happens to be current.
		       fixed bug #63097

2004-08-23  Martin Baulig  <martin@ximian.com>

	* XmlDataInferenceLoader.cs (Driver): Make this class internal,
	not public.

2004-08-18 Umadevi S <sumadevi@novell.com>
	* DataView.cs - Completed most of the event handling. 
	Thanks to Punit Todi <punit_todi@da-iict.org> for implementing most of it.
	Thanks to Boris Kirzner <borisk@mainsoft.com> for commenting and suggesting changes to the implementation.
	* DataTable.cs - Changed Access modifiers of class/methods since it was used by DataView.

2004-08-06  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : DataSet's ExtendedProperties were not XmlConverted.

2004-08-05  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlConstants.cs : Added constants for "msprop" support.
	* DataSet.cs : ExtendedProperties should be written in the schema.
	  This fixes bug #61233.

2004-07-27  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : on serialization to XmlWriter, XmlConvert should be
	  used. There were also some culture dependency problems to write int.

2004-06-27  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataInferenceLoader.cs : It was not always filling relation
	  child table information correctly. This fixes bug #60742.

2004-06-23 Umadevi S <sumadevi@novell.com>
	* UniqueConstraint.cs :changed a ifdef true to ifdef NET_1_1

2004-06-22  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : Fixed ReadXml(). When ReadMode is ReadSchema and the
	  schema is inside the document element (as created in XmlWriteMode
	  .WriteSchema), it should read schema from that non-document element.
	  This fixes one case reported in bug #60470.

2004-06-20  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataInferenceLoader.cs : Kindly reject xml schema document as a
	  inference target. For bug #60470. (MS does not support schema
	  document inference and results in unconsistent dataset structure.)

2004-06-20  Atsushi Enomoto  <atsushi@ximian.com>

	* DataTableCollection.cs : reset the table's DataSet to null when
	  removing a table from this collection.
	* DataTable.cs : When Namespace is not specified explicitly, its
	  Namespace property reflects DataSet's Namespace if exist.
	  This fixes bug #60469.

2004-06-18  Gert Driesen <drieseng@users.sourceforge.net>

	* DBConcurrentcyException.cs: CRLF to LF
	* DataViewSetting.cs: CRLF to LF

2004-06-18  Gert Driesen <drieseng@users.sourceforge.net>

        * DataViewSetting.cs: renamed fields to match MS.NET

2004-06-18  Gert Driesen <drieseng@users.sourceforge.net>

        * DBConcurrencyException.cs: fixed serialization compatibility with
        MS.NET

2004-06-17  Boris Kirzner  <borisk@mainsoft.com>

	* ChangeLog : Fix for misspelled words.

2004-06-17  Boris Kirzner  <borisk@mainsoft.com>

	* DataRowCollection.cs : Removed onColumnRemoved since it is not in use.
	
2004-06-17  Boris Kirzner  <borisk@mainsoft.com>

	* DataTable.cs :
	  - Table stores default values for columns in special default values row. 
	  It is allocated once (in NewRow).
	  - DataTable.Copy rewrited. It works with uninitialized rows for better perfomance.
	  - OnRemoveColumn has nothing to perform by now.

2004-06-17  Boris Kirzner  <borisk@mainsoft.com>

	* DataRow.cs : 
	  - Changed access of original, current and proposed indexes to internal.
	  - ColumnErrors reviewed : now column errors stored in ArrayList and allocated on demand only.
	  - Added new DataRow constructor that creates uninitialized DataRow (used in DataTable.Copy).
	  - Use DataContainer.CopyValue and default values row for faster set of default values in row.
	  - SetColumnValue become CheckValue. Now it does not changes the value, but only checks for its correctness.
	  Care about Null and DBNull values is now in DataContainer.
	  - Use DataColumn.AutoIncrementValue and GetInt64 for faster set of autoincrement value.
	  - Use Datacontainer.CopyValue and default values row to speed up CheckChildRows.
	  - Fix in CopyState : clone column errors.
	  - Removed CollectionChanged and onColumnRemoved since we are not using both of them anymore.

2004-06-17  Boris Kirzner  <borisk@mainsoft.com>

	* DataColumnCollection.cs : 
	  - Fix : Add()	now delegates to Add(DataColumn).
	  - autoIncrement list holds DataColumn objects, and not just column names.

2004-06-17  Boris Kirzner  <borisk@mainsoft.com>

	* DataColumn.cs : 
	  - AutoIncrementValue fixes. Now AutoIncrement uses DataContainer.GetInt64 to avoid boxing.
	  - DefaultValue fixes. Default value from now on is also stored in special record in 
	  DataTable, so we're able to set default value for the column faster (typed).

	* DataSet.cs : children of non-root rows were not properly written.
	  Fixed bug #53959.

2004-06-10 Umadevi S <sumadevi@novell.com>
	* DataRelation.cs - Constructor
	- The datatypes of the parentcolumn(s) and the childcolumn(s) should match

2004-06-06  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlSchemaDataImporter.cs : We should fill Namespace for DataTable.

2004-06-04  Gert Driesen <drieseng@users.sourceforge.net>

	* Constraint.cs: marked methods internal to fix public API
	* ConstraintCollection.cs: to fix public API, use 
	DataTable.fInitInProgress to check whether initialization 
	of DataTable is in progress
	* DataColumn.cs: added stubs for missing methods
	* DataRowBuilder.cs: marked Table property internal to
	fix public API
	* DataSet.cs: removed extra empty destructor, marked 
	OnMergeFailed internal to fix public API
	* DataTable.cs: use fInitInProgress field to hold init
	status, to match MS.NET
	* DataView.cs: added missing attributes on IsOpen

2004-06-03  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : Use NameTable.Get() before calling LookupNamespace()
	  in XmlNamespaceManager.

2004-06-03  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : complex table content child was not properly added
	  when it is the only one child in the parent table. Fixed bug #53959.

2004-06-02  Gert Driesen <drieseng@users.sourceforge.net>
       * DataTableTypeConverter.cs: added
       * DataView.cs: added missing attribute on Table property
       * DataViewManager.cs: moved attribute to correct property
       * UniqueConstraint.cs: removed extra ReadOnly attribute from
        IsPrimaryKey property

2004-06-01  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRow.cs : ColumnsChanged event is not required in .ctor().

2004-06-01  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataReader.cs : type change is required before setting value
	  string to row item.

2004-05-31  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : Loop-break of the last fix was incorrect.

2004-05-31  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : When a row has no parent row but the table has parent
	  relation(s), that row had been always ignored.

2004-05-31  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataInferenceLoader.cs : Fixed GetMappedTable() that incorrectly
	  rejected same-named tables in different hierarchy. Thanks to Boris.

2004-05-31  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDiffLoader.cs : Added some Skip() that is required not to go to
	  infinite loop. Thanks to Boris for this fix.

2004-05-31  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataInferenceLoader.cs : XmlSchema elements should not be infered.
	  Thanks to Boris for this fix.

2004-05-30  Atsushi Enomoto  <atsushi@ximian.com>

	* DataTable.cs : serialization .ctor() should use XmlReadMode.DiffGram
	  for ReadXml(). Thanks to Boris.

2004-05-27  Boris Kirzner  <borisk@mainsoft.com>
	* DataRow.cs : 
		- CheckReadOnlyStatus : use typed (and faster comparing).
		- EndEdit : bug fix - do not dispose record if it holds original version.
		- SetValuesFromDataRecord : Take care about autoincrement columns.
		

2004-05-27  Atsushi Enomoto  <atsushi@ximian.com>

	* MergeManager.cs : don't output debug message to Console.

2004-05-27  Atsushi Enomoto  <atsushi@ximian.com>

	  structure. Thanks to Boris Kirzner for the fix.

2004-05-27  Umadevi S <sumadevi@novell.com>
         * DataRelationCollection.cs - fixed nunit test errors

2004-05-27  Umadevi S <sumadevi@novell.com>
	 * DataTableCollection.cs - fixed nunit test errors

2004-05-21  Atsushi Enomoto  <atsushi@ximian.com>

	* DataColumnCollection.cs : NullReferenceException was thrown when
	  the table was not found.
	* DataRowCollection.cs :
	  Find() just returns null for null value under MS.NET 1.1.
	  RemoveAt() should also avoid to call AcceptChanges() like Remove().
	* UniqueConstraint.cs : in AssertConstraint() throw ConstraintException
	  directly under MS.NET (for nunit test).

2004-05-21  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlSchemaDataImporter.cs : Setting startindex in LastIndexOf() 
	  caused problem on qualified name to get schema Field name.

2004-05-21  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataReader.cs : Now data reader is namespace aware in all places.
	  When table's namespace is different, it entered to infinite loop.

2004-05-19  Boris Kirzner  <borisk@mainsoft.com>
	* MergeManager.cs : AdjustSchema now updates by reference new created table,
	so in Merge you do not need to lookup for it (were unable to do this for unnamed tables).
	Code styling.
	
2004-05-19  Boris Kirzner  <borisk@mainsoft.com>

	* DataColumn.cs : In set_Item[int] - if autoincrement, adjust next autoincrement value.
	* DataColumnCollection.cs : fixed parantethes.
	* DataRow.cs : 
		- AcceptChanges : do nothing if row state is unchanged.
		- GetChildRows, GetParentRows  : bug fix (use correct index).
	* DataRowCollection.cs : bug fix (compare all row's values).
	* DataTable.cs : bug fix (use correct row version).
	
2004-05-20  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlSchemaDataImporter.cs : xs:positiveInteger is mapped to ulong.
	  When content type is Mixed, text column is not required (it is
	  required only when the complex type has no particle). 
	  "Repeated element" column is also created (considering maxOccurs=0 
	  and complex content extension).

2004-05-20  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlSchemaDataImporter.cs : XmlSchemaGroupBase was not handled 
	  properly.

2004-05-20  Atsushi Enomoto  <atsushi@ximian.com>

	  Fixed relation inference to consider attribute XPath.

2004-05-19  Atsushi Enomoto  <atsushi@ximian.com>

	* DataColumn.cs : Fixed set_Item[int]. Convert.ToInt64(DBNull.Value)
	  always fails.

2004-05-19  Boris Kirzner  <borisk@mainsoft.com>

	* DataColumn.cs - removed default member attribute.

2004-05-19  Boris Kirzner  <borisk@mainsoft.com>

	* DataColumn.cs,
	  DataColumnChangeEventArgs.cs,
	  DataColumnCollection.cs,
	  DataRow.cs,
	  DataRowCollection.cs,
	  DataTable.cs,
	  Index.cs : Data storage in the row is redesigned. Now data is stored in 
	  typed containers inside DataColumn. Row holds its versions as indexes inside
	  each of data container, accessed through the row that holds it.

2004-05-19  Boris Kirzner  <borisk@mainsoft.com>

	* UniqueConstraint.cs - added comment.
	
2004-05-19  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataInferenceLoader.cs : Don't add already-existing DataTable to
	  DataSet.

2004-05-17  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs,
	  XmlDataInferenceLoader.cs,
	  XmlDataReader.cs,
	  XmlSchemaDataImporter.cs : XmlDecode every local name to read and
	  XmlEncode every local name to write. This should fix bug #58268.

2004-05-17  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : Implemented ignored namespaces in InferXmlSchema().
	  Supported repeated elements. Removed MonoTODOs.

	  namespace and repeated elements.
	* XmlSchemaDataImporter.cs : Added mapping support classes.

2004-05-15  Atsushi Enomoto  <atsushi@ximian.com>

	* CustomDataClassGenerator.cs :
	  Added property parent "[foo]Row" and children "Get[foo]Row" support
	  for custom DataRow classes.
	  Fixed DataColumn property accessibility (public --> internal).

2004-05-14  Atsushi Enomoto  <atsushi@ximian.com>

	* CustomDataClassGenerator.cs :
	  - Put classes inside custom DataSet class.
	  - Added automatic DataRelation creation support.
	  - Added Constraints creation support. That is done separate from
	    relations, since they might be independently created.
	  - Added non-MS public DataRelation fields.
	  - Removed extraneous "DataRelation type generation" code.
	  - Fixed custom_dataset.Initialize() not to create "c" field that
	    was created more than once.
	  - Implemented AddxxxRow() that takes parameters for every column.

2004-05-14  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlSchemaDataImporter.cs : When primary key is used more than once,
	  DataRelation borked because of empty parent column name.

2004-05-14  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlSchemaDataImporter.cs : When Creating constraints with related
	  to DataRelation creation, also set PrimaryKey to the parent table.

2004-05-14  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlSchemaDataImporter.cs : 
	  Design change to add indirect table and relation structures.
	  Support for "relation" annotation for local element.
	  Support for repeatable simple element column (maxOccurs > 1).
	  Fixed handling of Nested property on DataRelation (for globally
	  annotated relation, Nested is false).

2004-05-13  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRow.cs : Added DataElement property to avoid storing every row-
	  element mapping. It stored even for nodes that should be removed.

2004-05-13  Umadevi S <sumadevi@novell.com>

	* RelationshipConverter.cs - Stubbed this class
	* DataRelation.cs - added TypeConveterAttribute

2004-05-12  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRow.cs : Added XmlDataElement initialization code.

2004-05-11  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataInferenceLoader.cs :
	  It now requires XmlDocument as input.  Improved identification of
	  DataSet element.  Removed extra lines.
	  Moved boresome design notes to bottom of the source and
	  added standalone runnable driver (not included on build).
	* DataSet.cs :
	  Update with related to the change above.
	  WriteXml() should call Flush() after writing. This fixes bug #58327.
	* XmlSchemaDataImporter.cs :
	  Improved indentification of DataSet element.

2004-05-11  Gert Driesen (drieseng@users.sourceforge.net)
	* DataTable: marked initStatus enum internal

2004-05-09  Gert Driesen (drieseng@users.sourceforge.net)
	* DataTable.cs: removed TypeConverterAttribute, marked RowsExist
	methods internal
	* DataRowView.cs: removed extra Error property
	* DataRow.cs: reduced accessibility of CollectionChanged method 
	to private
	* DataColumnPropertyDescriptor.cs: made class internal
	* DataColumn.cs: removed extra TypeConvertorAttribute
	* ConstrainCollection.cs: marked PostEndInit method internal

2004-05-07  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : 
	  In WriteXmlSchema(), when complex type contains simple type content
	  attributes must not added to XmlSchemaComplexType directly. It
	  causes schema compilation error.
	  DataRelation should not be output when related columns are hidden.

2004-05-07  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataInferenceReader.cs : Added. It does InferXmlSchema() (it is
	  also expected to do ReadXml(), but I will remove that feature and
	  support column reordering).
	* XmlSchemaDataImporter.cs : Always initialize dataset name.
	  Always set Nested and primary key for parent table.
	* XmlDataReader.cs : Now it is used.
	  Top level element might not match to dataset name nor any table 
	  name, but still possible to read content tables.
	  Handle empty element correctly in some places.
	  Handle Fragment mode (read up XmlReader to the end).
	* DataSet.cs : Modified InferXmlSchema() and ReadXml() to use
	  XmlDataInferenceLoader and XmlDataReader.

2004-05-06  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs :
	  Eliminated CRLF injection.
	  More clear message in Clear().
	  Updates reflecting XmlSchemaDataImporter change.
	  Added duplicate check for XmlSerializerNamespaces in BuildSchema().
	  Don't use xmlns attribute for UnhandledAttributes (its not mandatory
	  but that depends on different behavior from ms.net).
	  Set locale also for DataTable.
	  Add xs:element only when target namespace matches to the
	  element's namespace. Otherwise, add xs:import for external namespace.
	  Put xs:sequence for dataset element's particle _only when_ actual
	  contents exist.

2004-05-06  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataReader.cs : Added. This class will work better when our
	  schema inference and schema read engine gets improved. (It contains
	  standalone testable Driver class.)

2004-05-06  Atsushi Enomoto  <atsushi@ximian.com>

	* ForeignKeyConstraint.cs : Check step change. Existence then column
	  validity. just for tests.
	* XmlSchemaDataImporter.cs : code simplification. reduced extraneous
	  fields.

2004-05-05  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : Ignore empty content only when output type is diffgram.

2004-05-05  Atsushi Enomoto  <atsushi@ximian.com>

	* CustomDataClassGenerator.cs : Modified that DataSet contains each
	  DataTable field so that each table property can access them directly.
	  (plus, modified standalone code driver code: shouldn't affect)

2004-05-05  Boris Kirzner  <borisk@mainsoft.com>

	* DataView.cs , DataRowView.cs : Added implementation to basic methods and properties.
	  
2004-05-05  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlSchemaDataImporter.cs : 
	  SimpleContent column support.
	  Annotated relation support.
	  Top-level element is counted only when its type is complex.
	  xs:anyType is no longer treated as complex type.
	  dataset existence is mandatory now. 
	  Improved DataType and DefaultValue support.
	  Attribute namespace is properly handled now.
	  Prohibited attribute is now treated as hidden column.
	  Reject list or union simple type.

	  Still incomplete 1) to read relationship in some cases, 2) to 
	  determine whether an element is dataset or table, 3) thus to
	  exclude extraneous column, 4) to remove extraneous *_Id column.

2004-05-05  Atsushi Enomoto  <atsushi@ximian.com>

	* DataTable.cs :
	  We had better reuse DataSet's ReadXmlSchema() and ReadXml() in
	  serialization .ctor() (thus schema read/inference should be easier).
	  DataRowSorter should consider Table's Locale.

2004-05-05  Atsushi Enomoto  <atsushi@ximian.com>

	* DataColumnCollection.cs : We already had AutoIncrementValue(), so
	  use it instead of duplicating logic.

2004-05-05  Atsushi Enomoto  <atsushi@ximian.com>

	* ConstraintCollection.cs :
	  Use Table.CaseSensitive and Table.Locale to compare strings.
	  Duplicate constraint name exception does not occur under .NET 1.1.

2004-05-04  Lluis Sanchez Gual  <lluis@ximian.com>

	* XmlSchemaDataImporter.cs: Added little type check.

2004-05-04  Lluis Sanchez Gual  <lluis@ximian.com>

	* DataSet.cs: Implemented support for runtime serialization. Fixed support
	  for xml serialization.
	* XmlDiffLoader.cs: Skip diffgram element when it is empty.

2004-04-30  Umadevi S  <sumadevi@novell.com>
	* DataColumnCollection.cs : Fixed nunit test errors, removed TODOs
	* DataTableCollection.cs  : Tested and removed TODO
	* TypedDataSetGeneratorException.cs : Fixed a couple of TODOs	

2004-04-29  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRow.cs : My previous patch unintentionally reverted Boris patch.

2004-04-29  Boris Kirzner <borisk@mainsoft.com>

	* UniqueConstraint.cs : Constraint columns becaomes unique after adding constraint ifand only if 
	constraint is defined on single column.

2004-04-29  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRowCollection.cs : .NET 1.1 throws InvalidConstaintException,
	  not ArgumentException (maybe changed after 1.1).

2004-04-29  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRow.cs : When Column was added and it was AutoIncrement column,
	  it extended the item object array incorrectly.
	  (Plus tiny comment and incorrect indentation fix.)

2004-04-29  Boris Kirzner <borisk@mainsoft.com>

	* MergeManager.cs : added ( incomplete yet ) support for merging DataSet schema.

2004-04-29  Boris Kirzner <borisk@mainsoft.com>

	* DataRow.cs : Bug fix in CopyValuesToRow().
	
2004-04-29  Boris Kirzner <borisk@mainsoft.com>

	* UniqueConstraint.cs : There is no reason to mark constraint's columns as unique, because
	  each of the columns should not be unique, but only all the constraint's columns together.
	
2004-04-28  Boris Kirzner <borisk@mainsoft.com>
	* DataRow.cs :
	  - Perfomance fixes: 
		- Added using of list of autoIncrement columns
		- SetColumnValue receives also DataColumn to avoid duplicate lookup in DatacolumnCollection
	  - Fix in CheckNullConstraints
	  - Fix in this[] and HasVersion() : when evaluating an expression deleted rows values can be accessed.
	  - Fix in SetColumnValue() , added CanAccess() method to avoid case of accessing internal array values berore it actually allocated.
	  - Added onColumnRemoved() method to threat column removal accurately.
	
	* DataRowCollection.cs :
	  - Added using of DataRow._nullConstraintViolation (for perfomance fix in EndLoadData())
	  - Added method onColumnRemoved() - calls each row's onColumnRemoved() (to ensure column removal is treated accurately)
	
	* DataTable.cs :
	  - Call DataRowCollection.onColumnRemoved() in OnRemoveColumn() (to ensure column removal is treated accurately)
	
	* DataColumnCollection.cs :
	  - Perfomance fixes :
		- collection holds a list of its autoIncrement columns (avoids unnesessary lookup through whole collection)
		- collection holds mapping from column names to DataColumn objects (avoids lookup through whole collection).
		- automatic creation of column names rewrited (bug fixes + perfomance improvement)
	
	* DataColumn.cs :
	  - Uses autoincrement list of a table

2004-04-27  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataLoader.cs : Even when it should ignore schema, it was 
	  infering schema.
	* XmlSchemaDataImporter.cs : DataRelation creation support.
	  Improved "DataSet" element handing. When attributes are on the
	  element, it is not a "DataSet" element.
	  Fixed parent key column name.
	  Unique name creation is not required. Just raise an error.
	  Fill facet also for attribute types.

2004-04-27  Atsushi Enomoto  <atsushi@ximian.com>

	* DataRow.cs : Null check for CheckReadOnlyStatus() and
	  CheckNullConstraints(), with some coding guideline fixes.
	  Type check should be done by Type instance comparison.

2004-04-27  Atsushi Enomoto  <atsushi@ximian.com>

	* DataColumnCollection.cs : When add a column to the collection, fill
	  auto-increment column.

2004-04-26  Boris Kirzner <borisk@mainsoft.com>

	* DataColumn.cs : Small perfomance fix (avoid unnesessary string concatenation).
	
2004-04-26  Atsushi Enomoto  <atsushi@ximian.com>

	* CustomDataClassGenerator.cs : Added.
	* TypedDataSetGenerator.cs : Implemented Generate().
	  Changed GenerateIdName() to call CustomDataClassGenerator.MakeSafeName
	* XmlSchemaDataImporter.cs : Table Locale should be supplied.

2004-04-25  Boris Kirzner <borisk@mainsoft.com>

	* DataTable.cs : Small perfomance fix (avoid unnesessary string concatenation).
	
2004-04-25  Boris Kirzner <borisk@mainsoft.com>

	* Constraint.cs : Small perfomance fix (avoid unnesessary string concatenation).

2004-04-23 Umadevi S (sumadevi@novell.com)
	*  DataRow.cs: Checked BeginEdit,EndEdit,CancelEdit and Delete methods
	   - Added error handling to the above methods

2004-04-22  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : Data should be read when mode is IgnoreSchema (well,
	  the support is incomplete yet).
	* XmlDataLoader.cs : 
	  Reverted ReadModeSchema() argument change. XmlReadMode would be 
	  useful to handle IgnoreSchema.
	  Don't overwrite DataSetName when mode is not such kind.
	  Set Prefix and Namespace as well as DataSetName.
	  AllowDBNull looks set false by default for element column.
	  Set unique constraint as primary key when infering the table schema.

2004-04-21  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs : 
	  Never set null string for Prefix and Namespace.
	  In InferXmlSchema() when null XmlReader is passed, just do nothing.
	  In WriteXmlSchema(string), earlier try block.
	  In BuildSchema(), try to add serialization namespaces for each
	  namespaces in DataSet/DataTable/DataColumn.
	  Removed namespace argument from WriteColumnAsElement() and don't
	  overwrite when namespace is "". This fixes bug #57330.
	* DataColumn.cs : For Namespace and Prefix, never set null.

2004-04-21  Boris Kirzner <borisk@mainsoft.com>

	* XmlSchemaMapper.cs : Check for not null unique constraint in ReadXmlSchemaKeyref()
	  before creating and adding foreign key constraint and relation. 

2004-04-21  Boris Kirzner <borisk@mainsoft.com>

	* MergeManager.cs : In AdjustSchema() source table clone should be added
	  and not the table itself. 

2004-04-21  Boris Kirzner <borisk@mainsoft.com>

	* DataSet.cs : 
	  - CaseSensitive : Additional fix (removed unnesessary assignment).
	  - CopyProperties : Do not try to copy ExtendedProperties if the collection is empty.

2004-04-21  Boris Kirzner <borisk@mainsoft.com>

	* DataTable.cs : Ensure that DataSet property is not null before using it in Clear().
	  
2004-04-20  Boris Kirzner <borisk@mainsoft.com>

	* DataTable.cs : 
	  - EndLoadData() : perfomance fix in case of null constraint violation
	    during data load (also in DataRow.cs).
	  - CaseSensitive : If DataTable belongs to DataSet it should always use
	    DataSet.CaseSensitive untill explicitly changed.
	  - CopyProperties() : do not try to copy ExtendedProperties if the collection is empty.
	  
	* DataRow.cs :
	  - Pefromance fix in case of null constraint violation
	    during data load (also in DataTable.cs).
	  - CollectionChanged() : use correct column number after new DataColumn was added
	    (differs in case some DataColumn was previosly removed).
	  - EndEdit() - throw away  proposed values only after CheckChildRows() complete.

2004-04-20  Boris Kirzner <borisk@mainsoft.com>

	* DataColumnCollection.cs : Since unique constraint is added now
	  in DataColumn.SetTable() the additional creation of constraint in 
	  DataColumnCollection.Add() is redundant and causes exception - fixed.
	  
2004-04-19  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataLoader.cs : Added "never add data rows" mode.
	  Removed unused code. However, it is temporary fixes to unify
	  ReadXml() and InferXmlSchema().
	* DataSet.cs : Implemented InferXmlSchema(), though it is incomplete.

	  I'll create another XmlDataLoader since there are many problems
	  such that 1) it is too waste to read the entire xml into an
	  XmlDocument, 2) it does not handle attributes correctly, and 3) it
	  must handle "ignored namespaces".

2004-04-19  Atsushi Enomoto  <atsushi@ximian.com>

	* Added XmlSchemaDataImporter.cs (new schema reader).
	* DataSet.cs : Use XmlSchemaDataImporter (right now for DataSet only)
	  for ReadXmlSchema().
	  Let schema reading work to ReadXmlSchema().
	  Don't return ReadSchema when argument read mode was DiffGram.

2004-04-15 Umadevi S (sumadevi@novell.com)
	*  Updated Clone/Copy methods in DataSet along with Testcase
	*  ForeignKeyConstraint.cs - special ctor implemented 
	    Logic : ParentTable in the ctor - Since only name is given (not the DataTable object), we cannot associate any DataTable or DataSet right now.  So, only possible way is to do it when AddRange() is called. The ParentTable is searched in the DataSet  to which the calling DataTable belongs. And make the calling DataTable as ChildTable. In the PostAddRange() method check is addedd to perform the assignment of parent and child data columns once the information becomes available (When AddRange is called).
	* Changes in  ConstraintCollection.cs for the above
        Add (Constraint) - A check is performed to see if the constraint is ForeignKeyConstraint and whether data columns  are validated.  If no, whether it is called with AddRange(), If no, an Exception is thrown. AddRange() - PostAddRange() is called on the ForeignKeyConstraint object with the "table" as argument. Thanks to Deepak for the patch.

	* XmlSchemaMapper.cs : set parent key and foreign key info to 
	  DataRelation when reading refkey constraints.
	  Supply constraint name for fkey.

2004-04-15  Atsushi Enomoto  <atsushi@ximian.com>

	* XmlDataLoader.cs : Don't overwrite existing DataSetName. When read
	  mode is Auto, just ignore the schema if there is already schema info.
	* DataSet.cs : Similarly ignore schema info for XmlReadMode = Auto.

2004-04-14  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs :
	  - In MS output, XML declaration looks to have standalone decl (yes).
	  - ReadXml(reader) just calls to ReadXml(reader, XmlReadMode.Auto)
	  - ReadXml(reader, mode)
	    1) return originally specified mode, instead of (always) Auto. 
	    2) Check empty reader.
	    3) Check diffgram schema and content separately.
	    4) When diffgram exists, remaining (the same-level) contents 
	       won't be consumed. 
	    5) Similar fact should be applied, but somewhat different. 
	       InferSchema and IgnoreSchema just skips, Fragment reads both
	       schema and content, others just reads schema.
	  - Removed unused code.
	* XmlDataLoader.cs :
	  - Read() should skip in some ReadMode.
	  - Don't compare schema element name as case-insensitive (well,
	    should schemas be checked here?)
	  - Avoided BuildDocument() not to create confusing DataSet
	    document element.
	  - Don't add any tables when reader has single element.
	* XmlDiffLoader.cs :
	  When target table was not found, MS.NET doesn't raise an error.
	* XmlSchemaMapper.cs :
	  When XmlSchema.Read() left xml reader at </xs:schema>, read once.

2004-04-13  Atsushi Enomoto  <atsushi@ximian.com>

	* DataSet.cs :
	  - InferXmlSchema(): Throw explicit NotImplementedException now.
	  - Don't put XML declaration everywhere. Write just for filename arg.
	  - xmlns="" should not be written. Maybe WebService problem is 
	    because default namespace is overwritten. This patch will keep
	    the WS problem away and actually fixes some unit tests (i.e. use
	    explicit String.Empty for null namespace in WriteStartElement()).
	  - MoveToContent() should always be called, not only when 
	    LocalName="xml". It will ignore prolog (DTD, PI, comment etc.).
	  - Even XmlReadMode is DiffGram, reader might not be "diffgram"
	    element. As to MSDN, diffgram does not contain schema.

2004-04-13  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* DataTable.cs: made _initStatus private so that System.Data is CLS
	compliant.

2004-04-13 Umadevi S   <sumadevi@novell.com>
	*  UniqueConstraint.cs:
	*  ConstraintCollection.cs:
	*  DataTable.cs:
	- Implemented a Constructor for UniqueConstraint.cs
	- Used  EndInit on DataTable  to call a delegate which adds the
	  constraints passed to the most recent call of AddRange().Used
	  AddRange() on ConstraintCollection to check whether
	  DataTable.BeginInit has occurred.  If yes, save the argument
	  constraint collection passed, then return.  If no, Check whether the
	  constraints are of type UniqueConstraint and initialized with the
	  special constructor  If yes Initialized the table property of this
	  UniqueConstraint object with table assosciated with the current
	  instance of ConstraintCollection class.

	  Added WriteIndividualTableContent(), for writing the contents of a single
	  table.
	  Changed BuildSchema and related methods, so it can generate a schema for

	  single datatable serialization).
	* DataTable.cs: Implemented serialization constructor and GetObjectData method.
	  Also implemented some ReadXmlSchema methods.
	* XmlDiffLoader.cs: Read and process the xml document directly from XmlReader,
