3 * DataSet.cs : clear UnhandledAttributes ArrayList before generating
4 next element column schema. This fixes bug #68256.
6 2004-10-12 Atsushi Enomoto <atsushi@ximian.com>
8 * DataSet.cs : now xs:schema contains xmlns="".
11 2004-10-12 Atsushi Enomoto <atsushi@ximian.com>
13 * DataSet.cs : DBNull attribute column should not be written as
14 empty attribute. This fixes bug #68007.
16 2004-10-12 Atsushi Enomoto <atsushi@ximian.com>
18 * DataSet.cs, XmlConstant.cs, XmlSchemaDataImporter.cs:
19 DataColumn.ReadOnly was not handled. This fixes bug #68005.
20 Attribute defaultValue was not handled too.
22 2004-10-08 Atsushi Enomoto <atsushi@ximian.com>
24 * DataSet.cs : Yesterday's fix was different and broke the build :(
26 2004-10-07 Atsushi Enomoto <atsushi@ximian.com>
29 - When AllowDBNull is false on attribute DataColumn, its schema
30 should contain use="required". This fixes bug #66792.
31 - If MaxLength is set on attribute DataColumn, the mapped schema
32 type should contain maxLength facet. This fixes bug #66793.
34 2004-10-04 Atsushi Enomoto <atsushi@ximian.com>
36 * DataSet.cs : For a row, when a relation is not nested, then it is
37 still output target since it won't be written as a child of its
38 parent. It fixes bug #66379.
40 2004-10-03 Atsushi Enomoto <atsushi@ximian.com>
42 * DataSet.cs : Attribute constraint field XPath must be written as
43 @blah. This fixes bug #66366.
45 2004-09-28 Umadevi S <sumadevi@novell.com>
46 * DataRow.cs - checked for Enforceconstraints, while using indices to search for related rows
48 2004-09-24 Sureshkumar T <tsureshkumar@novell.com>
50 * DataSet.cs : Don't check constraints for dataset clear
51 * DataRowCollection.cs : check for EnforceConstraints flag
52 before checking foriegn key constraints in Clear method
53 * DataTable.cs : Redundant checking removed in Clear method as it is
54 checked in DataRowCollection.Clear method.
56 2004-09-21 Sureshkumar T <tsureshkumar@novell.com>
58 * DataRow.cs: Added a new original row cache, if the current row happens
59 to be the original row. fixed bug #63097
61 2004-08-06 Atsushi Enomoto <atsushi@ximian.com>
63 * DataSet.cs : DataSet's ExtendedProperties were not XmlConverted.
65 2004-08-05 Atsushi Enomoto <atsushi@ximian.com>
67 * XmlConstants.cs : Added constants for "msprop" support.
68 * DataSet.cs : ExtendedProperties should be written in the schema.
69 This fixes bug #61233.
71 2004-07-27 Atsushi Enomoto <atsushi@ximian.com>
73 * DataSet.cs : on serialization to XmlWriter, XmlConvert should be
74 used. There were also some culture dependency problems to write int.
76 2004-06-27 Atsushi Enomoto <atsushi@ximian.com>
78 * XmlDataInferenceLoader.cs : It was not always filling relation
79 child table information correctly. This fixes bug #60742.
81 2004-06-23 Umadevi S <sumadevi@novell.com>
82 * UniqueConstraint.cs :changed a ifdef true to ifdef NET_1_1
84 2004-06-22 Atsushi Enomoto <atsushi@ximian.com>
86 * DataSet.cs : Fixed ReadXml(). When ReadMode is ReadSchema and the
87 schema is inside the document element (as created in XmlWriteMode
88 .WriteSchema), it should read schema from that non-document element.
89 This fixes one case reported in bug #60470.
91 2004-06-20 Atsushi Enomoto <atsushi@ximian.com>
93 * XmlDataInferenceLoader.cs : Kindly reject xml schema document as a
94 inference target. For bug #60470. (MS does not support schema
95 document inference and results in unconsistent dataset structure.)
97 2004-06-20 Atsushi Enomoto <atsushi@ximian.com>
99 * DataTableCollection.cs : reset the table's DataSet to null when
100 removing a table from this collection.
101 * DataTable.cs : When Namespace is not specified explicitly, its
102 Namespace property reflects DataSet's Namespace if exist.
103 This fixes bug #60469.
105 2004-06-18 Gert Driesen <drieseng@users.sourceforge.net>
107 * DBConcurrentcyException.cs: CRLF to LF
108 * DataViewSetting.cs: CRLF to LF
110 2004-06-18 Gert Driesen <drieseng@users.sourceforge.net>
112 * DataViewSetting.cs: renamed fields to match MS.NET
114 2004-06-18 Gert Driesen <drieseng@users.sourceforge.net>
116 * DBConcurrencyException.cs: fixed serialization compatibility with
119 2004-06-17 Boris Kirzner <borisk@mainsoft.com>
121 * ChangeLog : Fix for misspelled words.
123 2004-06-17 Boris Kirzner <borisk@mainsoft.com>
125 * DataRowCollection.cs : Removed onColumnRemoved since it is not in use.
127 2004-06-17 Boris Kirzner <borisk@mainsoft.com>
130 - Table stores default values for columns in special default values row.
131 It is allocated once (in NewRow).
132 - DataTable.Copy rewrited. It works with uninitialized rows for better perfomance.
133 - OnRemoveColumn has nothing to perform by now.
135 2004-06-17 Boris Kirzner <borisk@mainsoft.com>
138 - Changed access of original, current and proposed indexes to internal.
139 - ColumnErrors reviewed : now column errors stored in ArrayList and allocated on demand only.
140 - Added new DataRow constructor that creates uninitialized DataRow (used in DataTable.Copy).
141 - Use DataContainer.CopyValue and default values row for faster set of default values in row.
142 - SetColumnValue become CheckValue. Now it does not changes the value, but only checks for its correctness.
143 Care about Null and DBNull values is now in DataContainer.
144 - Use DataColumn.AutoIncrementValue and GetInt64 for faster set of autoincrement value.
145 - Use Datacontainer.CopyValue and default values row to speed up CheckChildRows.
146 - Fix in CopyState : clone column errors.
147 - Removed CollectionChanged and onColumnRemoved since we are not using both of them anymore.
149 2004-06-17 Boris Kirzner <borisk@mainsoft.com>
151 * DataColumnCollection.cs :
152 - Fix : Add() now delegates to Add(DataColumn).
153 - autoIncrement list holds DataColumn objects, and not just column names.
155 2004-06-17 Boris Kirzner <borisk@mainsoft.com>
158 - AutoIncrementValue fixes. Now AutoIncrement uses DataContainer.GetInt64 to avoid boxing.
159 - DefaultValue fixes. Default value from now on is also stored in special record in
160 DataTable, so we're able to set default value for the column faster (typed).
163 2004-06-15 Atsushi Enomoto <atsushi@ximian.com>
165 * DataSet.cs : children of non-root rows were not properly written.
168 2004-06-10 Umadevi S <sumadevi@novell.com>
169 * DataRelation.cs - Constructor
170 - The datatypes of the parentcolumn(s) and the childcolumn(s) should match
172 2004-06-06 Atsushi Enomoto <atsushi@ximian.com>
174 * XmlSchemaDataImporter.cs : We should fill Namespace for DataTable.
176 2004-06-04 Gert Driesen <drieseng@users.sourceforge.net>
178 * Constraint.cs: marked methods internal to fix public API
179 * ConstraintCollection.cs: to fix public API, use
180 DataTable.fInitInProgress to check whether initialization
181 of DataTable is in progress
182 * DataColumn.cs: added stubs for missing methods
183 * DataRowBuilder.cs: marked Table property internal to
185 * DataSet.cs: removed extra empty destructor, marked
186 OnMergeFailed internal to fix public API
187 * DataTable.cs: use fInitInProgress field to hold init
188 status, to match MS.NET
189 * DataView.cs: added missing attributes on IsOpen
191 2004-06-03 Atsushi Enomoto <atsushi@ximian.com>
193 * DataSet.cs : Use NameTable.Get() before calling LookupNamespace()
194 in XmlNamespaceManager.
196 2004-06-03 Atsushi Enomoto <atsushi@ximian.com>
198 * DataSet.cs : complex table content child was not properly added
199 when it is the only one child in the parent table. Fixed bug #53959.
201 2004-06-02 Gert Driesen <drieseng@users.sourceforge.net>
202 * DataTableTypeConverter.cs: added
203 * DataView.cs: added missing attribute on Table property
204 * DataViewManager.cs: moved attribute to correct property
205 * UniqueConstraint.cs: removed extra ReadOnly attribute from
206 IsPrimaryKey property
208 2004-06-01 Atsushi Enomoto <atsushi@ximian.com>
210 * DataRow.cs : ColumnsChanged event is not required in .ctor().
212 2004-06-01 Atsushi Enomoto <atsushi@ximian.com>
214 * XmlDataReader.cs : type change is required before setting value
217 2004-05-31 Atsushi Enomoto <atsushi@ximian.com>
219 * DataSet.cs : Loop-break of the last fix was incorrect.
221 2004-05-31 Atsushi Enomoto <atsushi@ximian.com>
223 * DataSet.cs : When a row has no parent row but the table has parent
224 relation(s), that row had been always ignored.
226 2004-05-31 Atsushi Enomoto <atsushi@ximian.com>
228 * XmlDataInferenceLoader.cs : Fixed GetMappedTable() that incorrectly
229 rejected same-named tables in different hierarchy. Thanks to Boris.
231 2004-05-31 Atsushi Enomoto <atsushi@ximian.com>
233 * XmlDiffLoader.cs : Added some Skip() that is required not to go to
234 infinite loop. Thanks to Boris for this fix.
236 2004-05-31 Atsushi Enomoto <atsushi@ximian.com>
238 * XmlDataInferenceLoader.cs : XmlSchema elements should not be infered.
239 Thanks to Boris for this fix.
241 2004-05-30 Atsushi Enomoto <atsushi@ximian.com>
243 * DataTable.cs : serialization .ctor() should use XmlReadMode.DiffGram
244 for ReadXml(). Thanks to Boris.
246 2004-05-27 Boris Kirzner <borisk@mainsoft.com>
248 - CheckReadOnlyStatus : use typed (and faster comparing).
249 - EndEdit : bug fix - do not dispose record if it holds original version.
250 - SetValuesFromDataRecord : Take care about autoincrement columns.
253 2004-05-27 Atsushi Enomoto <atsushi@ximian.com>
255 * MergeManager.cs : don't output debug message to Console.
257 2004-05-27 Atsushi Enomoto <atsushi@ximian.com>
259 * XmlDataInferenceLoader.cs : Namespace are not imported to the table
260 structure. Thanks to Boris Kirzner for the fix.
262 2004-05-27 Umadevi S <sumadevi@novell.com>
263 * DataRelationCollection.cs - fixed nunit test errors
265 2004-05-27 Umadevi S <sumadevi@novell.com>
266 * DataTableCollection.cs - fixed nunit test errors
268 2004-05-21 Atsushi Enomoto <atsushi@ximian.com>
270 * DataColumnCollection.cs : NullReferenceException was thrown when
271 the table was not found.
272 * DataRowCollection.cs :
273 Find() just returns null for null value under MS.NET 1.1.
274 RemoveAt() should also avoid to call AcceptChanges() like Remove().
275 * UniqueConstraint.cs : in AssertConstraint() throw ConstraintException
276 directly under MS.NET (for nunit test).
278 2004-05-21 Atsushi Enomoto <atsushi@ximian.com>
280 * XmlSchemaDataImporter.cs : Setting startindex in LastIndexOf()
281 caused problem on qualified name to get schema Field name.
283 2004-05-21 Atsushi Enomoto <atsushi@ximian.com>
285 * XmlDataReader.cs : Now data reader is namespace aware in all places.
286 When table's namespace is different, it entered to infinite loop.
288 2004-05-19 Boris Kirzner <borisk@mainsoft.com>
289 * MergeManager.cs : AdjustSchema now updates by reference new created table,
290 so in Merge you do not need to lookup for it (were unable to do this for unnamed tables).
293 2004-05-19 Boris Kirzner <borisk@mainsoft.com>
295 * DataColumn.cs : In set_Item[int] - if autoincrement, adjust next autoincrement value.
296 * DataColumnCollection.cs : fixed parantethes.
298 - AcceptChanges : do nothing if row state is unchanged.
299 - GetChildRows, GetParentRows : bug fix (use correct index).
300 * DataRowCollection.cs : bug fix (compare all row's values).
301 * DataTable.cs : bug fix (use correct row version).
303 2004-05-20 Atsushi Enomoto <atsushi@ximian.com>
305 * XmlSchemaDataImporter.cs : xs:positiveInteger is mapped to ulong.
306 When content type is Mixed, text column is not required (it is
307 required only when the complex type has no particle).
308 "Repeated element" column is also created (considering maxOccurs=0
309 and complex content extension).
311 2004-05-20 Atsushi Enomoto <atsushi@ximian.com>
313 * XmlSchemaDataImporter.cs : XmlSchemaGroupBase was not handled
316 2004-05-20 Atsushi Enomoto <atsushi@ximian.com>
318 * XmlSchemaDataImporter.cs : Removed unused code and extra MonoTODO.
319 Fixed relation inference to consider attribute XPath.
321 2004-05-19 Atsushi Enomoto <atsushi@ximian.com>
323 * DataColumn.cs : Fixed set_Item[int]. Convert.ToInt64(DBNull.Value)
326 2004-05-19 Boris Kirzner <borisk@mainsoft.com>
328 * DataColumn.cs - removed default member attribute.
330 2004-05-19 Boris Kirzner <borisk@mainsoft.com>
333 DataColumnChangeEventArgs.cs,
334 DataColumnCollection.cs,
336 DataRowCollection.cs,
338 Index.cs : Data storage in the row is redesigned. Now data is stored in
339 typed containers inside DataColumn. Row holds its versions as indexes inside
340 each of data container, accessed through the row that holds it.
342 2004-05-19 Boris Kirzner <borisk@mainsoft.com>
344 * UniqueConstraint.cs - added comment.
346 2004-05-19 Atsushi Enomoto <atsushi@ximian.com>
348 * XmlDataInferenceLoader.cs : Don't add already-existing DataTable to
351 2004-05-17 Atsushi Enomoto <atsushi@ximian.com>
354 XmlDataInferenceLoader.cs,
356 XmlSchemaDataImporter.cs : XmlDecode every local name to read and
357 XmlEncode every local name to write. This should fix bug #58268.
359 2004-05-17 Atsushi Enomoto <atsushi@ximian.com>
361 * DataSet.cs : Implemented ignored namespaces in InferXmlSchema().
362 Supported repeated elements. Removed MonoTODOs.
363 * XmlDataInferenceLoader.cs : Design change to support ignored
364 namespace and repeated elements.
365 * XmlSchemaDataImporter.cs : Added mapping support classes.
367 2004-05-15 Atsushi Enomoto <atsushi@ximian.com>
369 * CustomDataClassGenerator.cs :
370 Added property parent "[foo]Row" and children "Get[foo]Row" support
371 for custom DataRow classes.
372 Fixed DataColumn property accessibility (public --> internal).
374 2004-05-14 Atsushi Enomoto <atsushi@ximian.com>
376 * CustomDataClassGenerator.cs :
377 - Put classes inside custom DataSet class.
378 - Added automatic DataRelation creation support.
379 - Added Constraints creation support. That is done separate from
380 relations, since they might be independently created.
381 - Added non-MS public DataRelation fields.
382 - Removed extraneous "DataRelation type generation" code.
383 - Fixed custom_dataset.Initialize() not to create "c" field that
384 was created more than once.
385 - Implemented AddxxxRow() that takes parameters for every column.
387 2004-05-14 Atsushi Enomoto <atsushi@ximian.com>
389 * XmlSchemaDataImporter.cs : When primary key is used more than once,
390 DataRelation borked because of empty parent column name.
392 2004-05-14 Atsushi Enomoto <atsushi@ximian.com>
394 * XmlSchemaDataImporter.cs : When Creating constraints with related
395 to DataRelation creation, also set PrimaryKey to the parent table.
397 2004-05-14 Atsushi Enomoto <atsushi@ximian.com>
399 * XmlSchemaDataImporter.cs :
400 Design change to add indirect table and relation structures.
401 Support for "relation" annotation for local element.
402 Support for repeatable simple element column (maxOccurs > 1).
403 Fixed handling of Nested property on DataRelation (for globally
404 annotated relation, Nested is false).
406 2004-05-13 Atsushi Enomoto <atsushi@ximian.com>
408 * DataRow.cs : Added DataElement property to avoid storing every row-
409 element mapping. It stored even for nodes that should be removed.
411 2004-05-13 Umadevi S <sumadevi@novell.com>
413 * RelationshipConverter.cs - Stubbed this class
414 * DataRelation.cs - added TypeConveterAttribute

429 * DataRow.cs : Added XmlDataElement initialization code.
431 2004-05-11 Atsushi Enomoto <atsushi@ximian.com>
433 * XmlDataInferenceLoader.cs :
434 It now requires XmlDocument as input. Improved identification of
435 DataSet element. Removed extra lines.
436 Moved boresome design notes to bottom of the source and
437 added standalone runnable driver (not included on build).
439 Update with related to the change above.
440 WriteXml() should call Flush() after writing. This fixes bug #58327.
441 * XmlSchemaDataImporter.cs :
442 Improved indentification of DataSet element.
444 2004-05-11 Gert Driesen (drieseng@users.sourceforge.net)
445 * DataTable: marked initStatus enum internal
447 2004-05-09 Gert Driesen (drieseng@users.sourceforge.net)

454 * DataColumn.cs: removed extra TypeConvertorAttribute
455 * ConstrainCollection.cs: marked PostEndInit method internal
457 2004-05-07 Atsushi Enomoto <atsushi@ximian.com>
460 In WriteXmlSchema(), when complex type contains simple type content
461 attributes must not added to XmlSchemaComplexType directly. It
462 causes schema compilation error.
463 DataRelation should not be output when related columns are hidden.
465 2004-05-07 Atsushi Enomoto <atsushi@ximian.com>
467 * XmlDataInferenceReader.cs : Added. It does InferXmlSchema() (it is
468 also expected to do ReadXml(), but I will remove that feature and
469 support column reordering).
470 * XmlSchemaDataImporter.cs : Always initialize dataset name.
471 Always set Nested and primary key for parent table.
472 * XmlDataReader.cs : Now it is used.
473 Top level element might not match to dataset name nor any table
474 name, but still possible to read content tables.
475 Handle empty element correctly in some places.
476 Handle Fragment mode (read up XmlReader to the end).
477 * DataSet.cs : Modified InferXmlSchema() and ReadXml() to use
478 XmlDataInferenceLoader and XmlDataReader.
480 2004-05-06 Atsushi Enomoto <atsushi@ximian.com>
483 Eliminated CRLF injection.
484 More clear message in Clear().
485 Updates reflecting XmlSchemaDataImporter change.
486 Added duplicate check for XmlSerializerNamespaces in BuildSchema().
487 Don't use xmlns attribute for UnhandledAttributes (its not mandatory
488 but that depends on different behavior from ms.net).
489 Set locale also for DataTable.
490 Add xs:element only when target namespace matches to the
491 element's namespace. Otherwise, add xs:import for external namespace.
492 Put xs:sequence for dataset element's particle _only when_ actual
495 2004-05-06 Atsushi Enomoto <atsushi@ximian.com>
497 * XmlDataReader.cs : Added. This class will work better when our
498 schema inference and schema read engine gets improved. (It contains
499 standalone testable Driver class.)
501 2004-05-06 Atsushi Enomoto <atsushi@ximian.com>
503 * ForeignKeyConstraint.cs : Check step change. Existence then column
504 validity. just for tests.
505 * XmlSchemaDataImporter.cs : code simplification. reduced extraneous
508 2004-05-05 Atsushi Enomoto <atsushi@ximian.com>
510 * DataSet.cs : Ignore empty content only when output type is diffgram.
512 2004-05-05 Atsushi Enomoto <atsushi@ximian.com>
514 * CustomDataClassGenerator.cs : Modified that DataSet contains each
515 DataTable field so that each table property can access them directly.
516 (plus, modified standalone code driver code: shouldn't affect)
518 2004-05-05 Boris Kirzner <borisk@mainsoft.com>
520 * DataView.cs , DataRowView.cs : Added implementation to basic methods and properties.
522 2004-05-05 Atsushi Enomoto <atsushi@ximian.com>
524 * XmlSchemaDataImporter.cs :
525 SimpleContent column support.
526 Annotated relation support.
527 Top-level element is counted only when its type is complex.
528 xs:anyType is no longer treated as complex type.
529 dataset existence is mandatory now.
530 Improved DataType and DefaultValue support.
531 Attribute namespace is properly handled now.
532 Prohibited attribute is now treated as hidden column.
533 Reject list or union simple type.
535 Still incomplete 1) to read relationship in some cases, 2) to
536 determine whether an element is dataset or table, 3) thus to
537 exclude extraneous column, 4) to remove extraneous *_Id column.
539 2004-05-05 Atsushi Enomoto <atsushi@ximian.com>
542 We had better reuse DataSet's ReadXmlSchema() and ReadXml() in
543 serialization .ctor() (thus schema read/inference should be easier).
544 DataRowSorter should consider Table's Locale.
546 2004-05-05 Atsushi Enomoto <atsushi@ximian.com>
548 * DataColumnCollection.cs : We already had AutoIncrementValue(), so
549 use it instead of duplicating logic.
551 2004-05-05 Atsushi Enomoto <atsushi@ximian.com>
553 * ConstraintCollection.cs :
554 Use Table.CaseSensitive and Table.Locale to compare strings.
555 Duplicate constraint name exception does not occur under .NET 1.1.
557 2004-05-04 Lluis Sanchez Gual <lluis@ximian.com>
559 * XmlSchemaDataImporter.cs: Added little type check.
561 2004-05-04 Lluis Sanchez Gual <lluis@ximian.com>
563 * DataSet.cs: Implemented support for runtime serialization. Fixed support
564 for xml serialization.
565 * XmlDiffLoader.cs: Skip diffgram element when it is empty.
567 2004-04-30 Umadevi S <sumadevi@novell.com>
568 * DataColumnCollection.cs : Fixed nunit test errors, removed TODOs
569 * DataTableCollection.cs : Tested and removed TODO
570 * TypedDataSetGeneratorException.cs : Fixed a couple of TODOs
572 2004-04-29 Atsushi Enomoto <atsushi@ximian.com>
574 * DataRow.cs : My previous patch unintentionally reverted Boris patch.
576 2004-04-29 Boris Kirzner <borisk@mainsoft.com>
578 * UniqueConstraint.cs : Constraint columns becaomes unique after adding constraint ifand only if
579 constraint is defined on single column.
581 2004-04-29 Atsushi Enomoto <atsushi@ximian.com>
583 * DataRowCollection.cs : .NET 1.1 throws InvalidConstaintException,
584 not ArgumentException (maybe changed after 1.1).
586 2004-04-29 Atsushi Enomoto <atsushi@ximian.com>
588 * DataRow.cs : When Column was added and it was AutoIncrement column,
589 it extended the item object array incorrectly.
590 (Plus tiny comment and incorrect indentation fix.)
592 2004-04-29 Boris Kirzner <borisk@mainsoft.com>
594 * MergeManager.cs : added ( incomplete yet ) support for merging DataSet schema.
596 2004-04-29 Boris Kirzner <borisk@mainsoft.com>
598 * DataRow.cs : Bug fix in CopyValuesToRow().
600 2004-04-29 Boris Kirzner <borisk@mainsoft.com>
602 * UniqueConstraint.cs : There is no reason to mark constraint's columns as unique, because
603 each of the columns should not be unique, but only all the constraint's columns together.
605 2004-04-28 Boris Kirzner <borisk@mainsoft.com>
608 - Added using of list of autoIncrement columns
609 - SetColumnValue receives also DataColumn to avoid duplicate lookup in DatacolumnCollection
610 - Fix in CheckNullConstraints
611 - Fix in this[] and HasVersion() : when evaluating an expression deleted rows values can be accessed.
612 - Fix in SetColumnValue() , added CanAccess() method to avoid case of accessing internal array values berore it actually allocated.
613 - Added onColumnRemoved() method to threat column removal accurately.
615 * DataRowCollection.cs :
616 - Added using of DataRow._nullConstraintViolation (for perfomance fix in EndLoadData())
617 - Added method onColumnRemoved() - calls each row's onColumnRemoved() (to ensure column removal is treated accurately)
620 - Call DataRowCollection.onColumnRemoved() in OnRemoveColumn() (to ensure column removal is treated accurately)
622 * DataColumnCollection.cs :
624 - collection holds a list of its autoIncrement columns (avoids unnesessary lookup through whole collection)
625 - collection holds mapping from column names to DataColumn objects (avoids lookup through whole collection).
626 - automatic creation of column names rewrited (bug fixes + perfomance improvement)
629 - Uses autoincrement list of a table
631 2004-04-27 Atsushi Enomoto <atsushi@ximian.com>
633 * XmlDataLoader.cs : Even when it should ignore schema, it was
635 * XmlSchemaDataImporter.cs : DataRelation creation support.
636 Improved "DataSet" element handing. When attributes are on the
637 element, it is not a "DataSet" element.
638 Fixed parent key column name.
639 Unique name creation is not required. Just raise an error.
640 Fill facet also for attribute types.
642 2004-04-27 Atsushi Enomoto <atsushi@ximian.com>
644 * DataRow.cs : Null check for CheckReadOnlyStatus() and
645 CheckNullConstraints(), with some coding guideline fixes.
646 Type check should be done by Type instance comparison.
648 2004-04-27 Atsushi Enomoto <atsushi@ximian.com>
650 * DataColumnCollection.cs : When add a column to the collection, fill
651 auto-increment column.
653 2004-04-26 Boris Kirzner <borisk@mainsoft.com>
655 * DataColumn.cs : Small perfomance fix (avoid unnesessary string concatenation).
657 2004-04-26 Atsushi Enomoto <atsushi@ximian.com>
659 * CustomDataClassGenerator.cs : Added.
660 * TypedDataSetGenerator.cs : Implemented Generate().
661 Changed GenerateIdName() to call CustomDataClassGenerator.MakeSafeName
662 * XmlSchemaDataImporter.cs : Table Locale should be supplied.
664 2004-04-25 Boris Kirzner <borisk@mainsoft.com>
666 * DataTable.cs : Small perfomance fix (avoid unnesessary string concatenation).
668 2004-04-25 Boris Kirzner <borisk@mainsoft.com>
670 * Constraint.cs : Small perfomance fix (avoid unnesessary string concatenation).
672 2004-04-23 Umadevi S (sumadevi@novell.com)
673 * DataRow.cs: Checked BeginEdit,EndEdit,CancelEdit and Delete methods
674 - Added error handling to the above methods
676 2004-04-22 Atsushi Enomoto <atsushi@ximian.com>
678 * DataSet.cs : Data should be read when mode is IgnoreSchema (well,
679 the support is incomplete yet).
681 Reverted ReadModeSchema() argument change. XmlReadMode would be
682 useful to handle IgnoreSchema.
683 Don't overwrite DataSetName when mode is not such kind.
684 Set Prefix and Namespace as well as DataSetName.
685 AllowDBNull looks set false by default for element column.
686 Set unique constraint as primary key when infering the table schema.
688 2004-04-21 Atsushi Enomoto <atsushi@ximian.com>
691 Never set null string for Prefix and Namespace.
692 In InferXmlSchema() when null XmlReader is passed, just do nothing.
693 In WriteXmlSchema(string), earlier try block.
694 In BuildSchema(), try to add serialization namespaces for each
695 namespaces in DataSet/DataTable/DataColumn.
696 Removed namespace argument from WriteColumnAsElement() and don't
697 overwrite when namespace is "". This fixes bug #57330.
698 * DataColumn.cs : For Namespace and Prefix, never set null.
700 2004-04-21 Boris Kirzner <borisk@mainsoft.com>
702 * XmlSchemaMapper.cs : Check for not null unique constraint in ReadXmlSchemaKeyref()
703 before creating and adding foreign key constraint and relation.
705 2004-04-21 Boris Kirzner <borisk@mainsoft.com>
707 * MergeManager.cs : In AdjustSchema() source table clone should be added
708 and not the table itself.
710 2004-04-21 Boris Kirzner <borisk@mainsoft.com>
713 - CaseSensitive : Additional fix (removed unnesessary assignment).
714 - CopyProperties : Do not try to copy ExtendedProperties if the collection is empty.
716 2004-04-21 Boris Kirzner <borisk@mainsoft.com>
718 * DataTable.cs : Ensure that DataSet property is not null before using it in Clear().
720 2004-04-20 Boris Kirzner <borisk@mainsoft.com>
723 - EndLoadData() : perfomance fix in case of null constraint violation
724 during data load (also in DataRow.cs).
725 - CaseSensitive : If DataTable belongs to DataSet it should always use
726 DataSet.CaseSensitive untill explicitly changed.
727 - CopyProperties() : do not try to copy ExtendedProperties if the collection is empty.
730 - Pefromance fix in case of null constraint violation
731 during data load (also in DataTable.cs).
732 - CollectionChanged() : use correct column number after new DataColumn was added
733 (differs in case some DataColumn was previosly removed).
734 - EndEdit() - throw away proposed values only after CheckChildRows() complete.
736 2004-04-20 Boris Kirzner <borisk@mainsoft.com>
738 * DataColumnCollection.cs : Since unique constraint is added now
739 in DataColumn.SetTable() the additional creation of constraint in
740 DataColumnCollection.Add() is redundant and causes exception - fixed.
742 2004-04-19 Atsushi Enomoto <atsushi@ximian.com>
744 * XmlDataLoader.cs : Added "never add data rows" mode.
745 Removed unused code. However, it is temporary fixes to unify
746 ReadXml() and InferXmlSchema().
747 * DataSet.cs : Implemented InferXmlSchema(), though it is incomplete.
749 I'll create another XmlDataLoader since there are many problems
750 such that 1) it is too waste to read the entire xml into an
751 XmlDocument, 2) it does not handle attributes correctly, and 3) it
752 must handle "ignored namespaces".
754 2004-04-19 Atsushi Enomoto <atsushi@ximian.com>
756 * Added XmlSchemaDataImporter.cs (new schema reader).
757 * DataSet.cs : Use XmlSchemaDataImporter (right now for DataSet only)
759 Let schema reading work to ReadXmlSchema().
760 Don't return ReadSchema when argument read mode was DiffGram.
762 2004-04-15 Umadevi S (sumadevi@novell.com)
763 * Updated Clone/Copy methods in DataSet along with Testcase
764 * ForeignKeyConstraint.cs - special ctor implemented
765 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).
766 * Changes in ConstraintCollection.cs for the above
767 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.
770 2004-04-15 Atsushi Enomoto <atsushi@ximian.com>
772 * XmlSchemaMapper.cs : set parent key and foreign key info to
773 DataRelation when reading refkey constraints.
774 Supply constraint name for fkey.
776 2004-04-15 Atsushi Enomoto <atsushi@ximian.com>
778 * XmlDataLoader.cs : Don't overwrite existing DataSetName. When read
779 mode is Auto, just ignore the schema if there is already schema info.
780 * DataSet.cs : Similarly ignore schema info for XmlReadMode = Auto.
782 2004-04-14 Atsushi Enomoto <atsushi@ximian.com>
785 - In MS output, XML declaration looks to have standalone decl (yes).
786 - ReadXml(reader) just calls to ReadXml(reader, XmlReadMode.Auto)
787 - ReadXml(reader, mode)
788 1) return originally specified mode, instead of (always) Auto.
789 2) Check empty reader.
790 3) Check diffgram schema and content separately.
791 4) When diffgram exists, remaining (the same-level) contents
793 5) Similar fact should be applied, but somewhat different.
794 InferSchema and IgnoreSchema just skips, Fragment reads both
795 schema and content, others just reads schema.
796 - Removed unused code.
798 - Read() should skip in some ReadMode.
799 - Don't compare schema element name as case-insensitive (well,
800 should schemas be checked here?)
801 - Avoided BuildDocument() not to create confusing DataSet
803 - Don't add any tables when reader has single element.
805 When target table was not found, MS.NET doesn't raise an error.
806 * XmlSchemaMapper.cs :
807 When XmlSchema.Read() left xml reader at </xs:schema>, read once.
809 2004-04-13 Atsushi Enomoto <atsushi@ximian.com>
812 - InferXmlSchema(): Throw explicit NotImplementedException now.
813 - Don't put XML declaration everywhere. Write just for filename arg.
814 - xmlns="" should not be written. Maybe WebService problem is
815 because default namespace is overwritten. This patch will keep
816 the WS problem away and actually fixes some unit tests (i.e. use
817 explicit String.Empty for null namespace in WriteStartElement()).
818 - MoveToContent() should always be called, not only when
819 LocalName="xml". It will ignore prolog (DTD, PI, comment etc.).
820 - Even XmlReadMode is DiffGram, reader might not be "diffgram"
821 element. As to MSDN, diffgram does not contain schema.
823 2004-04-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
825 * DataTable.cs: made _initStatus private so that System.Data is CLS
828 2004-04-13 Umadevi S <sumadevi@novell.com>
829 * UniqueConstraint.cs:
830 * ConstraintCollection.cs:
832 - Implemented a Constructor for UniqueConstraint.cs
833 - Used EndInit on DataTable to call a delegate which adds the
834 constraints passed to the most recent call of AddRange().Used
835 AddRange() on ConstraintCollection to check whether
836 DataTable.BeginInit has occurred. If yes, save the argument
837 constraint collection passed, then return. If no, Check whether the
838 constraints are of type UniqueConstraint and initialized with the
839 special constructor If yes Initialized the table property of this
840 UniqueConstraint object with table assosciated with the current
841 instance of ConstraintCollection class.
843 2004-04-07 Marek Safar <marek.safar@seznam.cz>

860 * DataTable.cs: Add rows to the row list if there is no filter.
862 2004-03-31 Juraj Skripsky <juraj@hotfeet.ch>
864 * DataColumn.cs : Setting Caption to null sets it to the empty string
865 (ms.net behaviour, testcase is in DataColumnTest).
867 * DataRow.cs : Evaluate DataColumn.Expression when such a column's
870 2004-03-30 Lluis Sanchez Gual <lluis@ximian.com>
872 * DataColumn.cs: In Expression setter, set the expression member even if
873 it is an empty string.
874 * DataSet.cs: Support serialization of byte[] columns.
875 * XmlDataLoader.cs: Support deserialization of Guid columns.
876 Set MappingType.Attribute to columns infered from attributes.
878 2004-03-29 Juraj Skripsky <juraj@hotfeet.ch>
880 * ExpressionElements.cs : remove
881 * DataColumn.cs, DataRelationCollection.cs, DataTable.cs :
882 Integration of new Mono.Data.SqlExpressions classes used in
883 DataTable.{Select, Compute}.
884 Fixes bug #55503 and lots of failures in DataTableTest.cs.
886 2004-03-28 Juraj Skripsky <juraj@hotfeet.ch>
888 * Index.cs: Simple fix in ComparePartialRowNonUnique.
889 This fixes bugs #56129 and #56014.
891 2004-03-25 Lluis Sanchez Gual <lluis@ximian.com>
893 * DataSet.cs: In WriteXml (string filename, XmlWriteMode mode), close the
894 stream after writing the dataset. This fixes bug #52581.
895 Also added several writer.Close into finally blocks, so writers are properly
896 closed in case of an exception.
898 2004-03-12 Andreas Nahr <ClassDevelopment@A-SoftTech.com>
900 * Constraint.cs: DO NOT USE the consts scheme if types can be referenced directly!

941 * DataRowCollection.cs (InsertAt): Add a check for null row. Replace check of IndexOf with RowId for
943 * DataSet.cs (GetTableSchema) : Add supprot for simple content columns. Change the condition for a case
944 when all column are attributes (elements count is 0), we still want to add the relations. No relations
945 can be on simple contents.
946 (AddUniqueConstraints) Check that the column of the constraint are not hidden.
947 (AddForeignKeys) Check that the relation has constraints attach to it.
948 * XmlConstants.cs : Added constant.
950 2004-02-04 Eran Domb <erand@mainsoft.com>
952 * DataSet.cs : GetSchemaSerializable() return null and not BuildSchema().

955 2004-02-04 Lluis Sanchez Gual <lluis@ximian.com>
957 * DataRow.cs: Added SetOriginalValue(), which is used to set the original
959 * DataRowCollection.cs: In InsertAt(), perform the correct checks and
961 * DataSet.cs: Fixed method GetChanges(): Parent rows of modified rows must
962 also be added to the dataset.
963 In WriteTable(), do not write unchanged rows when writing the original
964 version of the table.
965 Added WriteIndividualTableContent(), for writing the contents of a single
967 Changed BuildSchema and related methods, so it can generate a schema for
968 any set of tables, not just the tables of the dataset (needed for
969 single datatable serialization).
970 * DataTable.cs: Implemented serialization constructor and GetObjectData method.
971 Also implemented some ReadXmlSchema methods.
972 * XmlDiffLoader.cs: Read and process the xml document directly from XmlReader,
973 instead of loading the full dataset in an XmlDocument. It is faster and
974 saves memory. Also fixed several problems when generating the changes.
975 * XmlSchemaMapper.cs: Support reading schemas for single tables (used by
976 table serialization).
978 2004-02-02 Eran Domb <erand@mainsoft.com>
980 * DataSet.cs : Add indentation to the xml serialization only if we create the XmlWriter.

1000 (ReadXmlSchemaUnique) : Improve parsing of XPath. Set the constraint as a PK if needed,
1001 and add the constraint to the table.
1002 (ReadXmlSchemaKeyref) : Improve parsing of XPath. Create the FK constraint and add it to
1004 * DataSet.cs : Improving writing of unique constraints, and foriegn key constraint. Givving them the correct names.
1005 Writing more information to the schema for interoperability with ms.net.
1006 Improve diffgarm writing mode.
1009 2004-01-21 Atsushi Enomoto <atsushi@ximian.com>
1011 * TypedDataSetGenerator.cs : Implemented GenerateIdName().
1013 2004-01-21 Eran Domb <erand@mainsoft.com>
1015 * XmlDataLoader.cs (AddRowToTable) : Give thre new relation correct name.
1016 Do not set the child column to be AutoIncrement.
1017 Create the new column for the relation as MappingType.Hidden so they will not be serialized
1018 when writing the dataset to xml.
1020 2004-01-20 Atsushi Enomoto <atsushi@ximian.com>
1022 * Added missing TypedDataSetGenerator.cs.
1024 2004-01-08 Eran Domb <erand@mainsoft.com>
1026 * XmlSchemaMapper.cs : Fix a bug. Check if table already in DataSet before adding it.
1027 * DataSet.cs (ReadXml) : Fix bugs. Read correctly the xml file with XmlReadMode of DiffGram,
1028 InferSchema, ReadSchema and IgnoreSchema.
1029 * XmlDataLoader.cs : All modes use the same logic.
1030 * XmlDiffLoader.cs : Adding BuildXmlDocument method to the class.

1061 2003-12-17 Atsushi Enomoto <atsushi@ximian.com>
1063 * DataSet.cs, XmlDataLoader.cs : Table name should be encoded before
1064 they take shape of xml. This fixed bug #52240
1066 2003-12-16 Tim Coleman <tim@timcoleman.com>

1108 * DataRowCollection.cs (Remove) : Check if row state is Detached to avoid exception.
1110 * DataSet.cs (IXmlSerializable.ReadXml) : Do not call MoveToContent and ReadEndElement - the XmlSerializationReader does it.
1112 * DataTable.cs (PrimaryKey) : Fix bugs.
1113 (Compute) : First call Select. Then create ExpressionAggregate to aggregate the Select result.
1115 * DataTableCollection.cs (Add) : Fix a bug.

1728 2002-11-29 Ville Palo <vi64pa@koti.soon.fi>
1730 * DataSystem.Data.DataTableCollection.cs:
1731 Removed HashTable. There could be situations where DataTable
1732 is added to collection before it hava TableName. So using
1733 HashTable is impossible.
