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 have 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).
        
        
2004-06-15  Atsushi Enomoto  <atsushi@ximian.com>

        * 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>

        * XmlDataInferenceLoader.cs : Namespace are not imported to the table
          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>

        * XmlSchemaDataImporter.cs : Removed unused code and extra MonoTODO.
          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.
        * XmlDataInferenceLoader.cs : Design change to support ignored
          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

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

        * DataColumnCollection.cs - Added ResDescriptionAttribute
        * DataRelation.cs - Added TypeConverterAttribute
        * DataRelationCollection.cs - Added DefaultPropertyAttribute
        * DataRowView.cs - Added GetHashCode method with a TODO tag
        * DataSet.cs - Added DesignerAttribute
        * DataView.cs - Added DesignerAttribute
        * DataViewManager.cs - Added DesignerAttribute
        * DataViewSetting.cs - Added TypeConverterAttribute
        
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.
        

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

        * 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.

2004-04-07  Marek Safar  <marek.safar@seznam.cz>

2004-03-31  Juraj Skripsky <juraj@hotfeet.ch>

        * DataColumn.cs : Setting Caption to null sets it to the empty string
        (ms.net behaviour, testcase is in DataColumnTest).
        
        * DataRow.cs : Evaluate DataColumn.Expression when such a column's
        value is requested.

2004-03-30 Lluis Sanchez Gual <lluis@ximian.com>

        * DataColumn.cs: In Expression setter, set the expression member even if 
          it is an empty string.
        * DataSet.cs: Support serialization of byte[] columns.
        * XmlDataLoader.cs: Support deserialization  of Guid columns.

2004-03-25 Lluis Sanchez Gual <lluis@ximian.com>

        * DataSet.cs: In WriteXml (string filename, XmlWriteMode mode), close the
          stream after writing the dataset. This fixes bug #52581.
          Also added several writer.Close into finally blocks, so writers are properly
          closed in case of an exception.

2004-03-12  Andreas Nahr <ClassDevelopment@A-SoftTech.com>

        * Constraint.cs: DO NOT USE the consts scheme if types can be referenced directly!

2004-02-04 Eran Domb <erand@mainsoft.com>

        * DataRowCollection.cs (InsertAt): Add a check for null row. Replace check of IndexOf with RowId for
        better performance.
        * DataSet.cs (GetTableSchema) : Add supprot for simple content columns. Change the condition for a case
        when all column are attributes (elements count is 0), we still want to add the relations. No relations
        can be on simple contents.
        (AddUniqueConstraints) Check that the column of the constraint are not hidden.
        (AddForeignKeys) Check that the relation has constraints attach to it.
        * XmlConstants.cs : Added constant.

2004-02-04 Eran Domb <erand@mainsoft.com>
        
        * DataSet.cs : GetSchemaSerializable() return null and not BuildSchema().

2004-02-04 Lluis Sanchez Gual <lluis@ximian.com>

        * DataRow.cs: Added SetOriginalValue(), which is used to set the original
          value of a column.
        * DataRowCollection.cs: In InsertAt(), perform the correct checks and
          attach the row.

          also be added to the dataset.
          In WriteTable(), do not write unchanged rows when writing the original
          version of the table.
          Added WriteIndividualTableContent(), for writing the contents of a single
          table.
          Changed BuildSchema and related methods, so it can generate a schema for
          any set of tables, not just the tables of the dataset (needed 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,
          instead of loading the full dataset in an XmlDocument. It is faster and
          saves memory. Also fixed several problems when generating the changes.
        * XmlSchemaMapper.cs: Support reading schemas for single tables (used by
          table serialization).

        * XmlDataLoader.cs (AddRowToTable) : Give thre new relation correct name.
        Do not set the child column to be AutoIncrement.
        Create the new column for the relation as MappingType.Hidden so they will not be serialized
        when writing the dataset to xml.

2004-01-20 Atsushi Enomoto <atsushi@ximian.com>

        * Added missing TypedDataSetGenerator.cs.

        IndexOf (string name) methods, and item[string name] indexer
        now behave more like .NET with respect to case-sensitivity.
        That is if there is an exactly matching item then this one is used.
        If there is only one item differing in case then it used.
