1 tony 315 IBX Change Log version (2.4-0 Build 12473) Wed, 17 Feb 2021 10:49:57 +0000
2    
3     1. Firebird 4 support added.
4    
5     2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
6     extended precision NUMERIC fields are supported.
7    
8     3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
9    
10     4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
11     and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
12    
13     5. IBExtract now supports FB4 enhancements:
14     - new data types as above
15     - Identity column extensions
16     - Default user role
17     - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
18     - Internal Functions
19    
20     6. IBExtract: new event: OnExtractLines.
21    
22     7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
23    
24     8. IBXServices: Server version no. parsing now allows any letter before major version number
25     and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
26    
27     9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
28     format for rendering a time zone.
29    
30     10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
31     to convert TIME WITH TIME ZONE data type values to and from GMT.
32    
33     11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
34     IIBGUIInterface and IIBTimerInf respectively.
35    
36     12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
37     now accessible as properties of TIBDatabase and TIBTransaction respectively.
38    
39     13. String Fields: when a fixed character with (CHAR) field is returned, it is now
40     truncated to its fixed character width rather than being right padded with
41     white space to the maximum data size.
42    
43     14. TIBTable.Empty table. In additional to deleting all records in the underlying
44     table, the internal buffers are now also flushed ensuring that the TIBTable is
45     also empty.
46    
47     15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
48    
49     16. TIBXControlService descendents: DatabaseName may now be set using a database
50     connect string. The database name is extracted from the connect string.
51    
52     17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
53    
54     18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
55    
56     19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
57     not being present as required.
58    
59     20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
60     version that can be customised to work with other database drivers.
61    
62 tony 312 IBX Change Log version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
63 tony 308
64     1. TIBStringField: when a string value is read from a dataset buffer, if the
65     number of UTF8 characters exceeds the string size then string is truncated
66     to the maximum string size. This is usually a problem with fixed width columns
67     right padded with white space.
68    
69     2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
70     If SQLFiltered is set then when a dataset is opened, each line in the
71     SQLFilterParams property is assumed to be a SQL condition clause and
72     ANDed into the Where clause of the SQL Select statement provided as a
73     dataset property. Each such SQL condition thus acts as an additional filter
74 tony 315 on the dataset.
75 tony 308
76     3. The Filtered property inherited from TDataset is no longer used for SQL (server
77     side filters).
78    
79 tony 311 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
80     text matches complete entry.
81    
82     5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
83     dataset are active (avoids risk of access violation if master is inactive)
84    
85     6. TIBEvents: Registered property can now be set at design time even if database not open
86    
87     7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
88     This should prevent "spillover" of events between sessions.
89    
90     8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
91     This should ensure that the internal buffer is set up correctly and avoids
92     a duplicate initial row.
93    
94     9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
95     That is, the DataSize should be the field size * character set width. The
96     value returned by DataSize is now the same as the Dataset buffer size reserved
97     for the field.
98    
99 tony 312 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
100 tony 311
101     11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
102     and vice-versa. This may result in an exception being raised (correctly) for
103     older programs when using dataset fields added to a form and the database has been
104     upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
105     In such cases, the field needs to be deleted in the IDE fields editor and then
106     added back in.
107    
108 tony 312 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
109 tony 315 false if query contains only white space and not just empty.
110 tony 312
111 tony 311 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
112     should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
113     is cancelled.
114    
115 tony 315 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
116     called on a null field.
117    
118     14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
119     results in an empty dataTC86 Client side Filtered Dataset 1 X
120     set.
121    
122     15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
123     a cached update is applied and an exception is raised.
124    
125     16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
126    
127     17. Console Mode Local Database support: backup/restore should now work correctly.
128    
129     18. Local Database Support: if an upgrade fails, a downgrade is now performed if
130     possible and an exception raised.
131    
132     19. MinimumVersionNo added to Local Database Support. Database will not open if
133     below this version no. and upgrade not possible.
134    
135 tony 307 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
136 tony 306
137 tony 307 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
138     not SQL Identifiers are now supported.
139 tony 306
140 tony 307 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
141     passed to the Firebird engine for execution.
142 tony 306
143 tony 307 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
144     is made to scroll back.
145 tony 306
146 tony 307 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
147 tony 306
148 tony 307 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
149     only enclosed in double quotes in SQL dialect 3 and when it needs to be.
150 tony 306
151 tony 307 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
152     validated. If no match is found in the list of field names and the database has
153     been opened in SQL Dialect 3, then the ListField Name is converted to upper case
154     if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
155 tony 306
156 tony 307 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
157     with fpc 3.2.
158 tony 306
159 tony 307 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
160 tony 287
161    
162 tony 307 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
163     and is used to override the default settings in the client side "firebird.conf" This
164     includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
165     Each line of the string list should be a setting in the same format as "firebird.conf".
166     For example "WireCompression = true" in order to request wire compression on the client side.
167 tony 287
168 tony 307 Note: explicit settings in the client side "firebird.conf" appear to take precedence
169     over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
170     also require a compatible setting in the server side "firebird.conf". For example
171     "WireCompression = true" must also be set in the server's "firebird.conf" for wire
172     compression to be used.
173 tony 291
174 tony 307 Whether or not WireCompression or WireCrypt are in use can be checked using the information
175     returned with the Client/Server protocol version. See ibx/examples/dbadmin and
176     ibx/examples/dbinfo for examples of how to display this information.
177 tony 291
178 tony 307 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
179     is a "convenience" property. If set the "WireCompression=true" is added to the
180     ConfigOverrides. If unchecked then this setting is removed.
181 tony 291
182 tony 307 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
183     not "INT64".
184 tony 291
185 tony 307 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
186     These are:
187     property TimestampFormat: string;
188     property DateFormat: string;
189     property TimeFormat: string;
190 tony 291
191 tony 307 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
192     DATETIME and TIME. The format strings use the standard FPC date/time format
193     characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
194 tony 266
195 tony 307 If any of the above properties are set to an empty string, then the locale default
196     is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
197     locale default is extended by appending '.zzz' to include milliseconds.
198 tony 272
199 tony 307 TIBCSVDataOut by default sets these properties to the empty string, while the other
200     two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
201 tony 266
202 tony 307 5. New published property for TIBCSVDataOut:
203     property QuoteStrings: boolean (default true)
204 tony 266
205 tony 307 If false then strings are unquoted, otherwise, the QuoteChar property value is
206     used to delimit each and every string in the output.
207 tony 263
208 tony 307 6. New published properties for TIBCSVDataOut:
209     property FieldSeparator: string;
210     property HeaderSeparator: string;
211 tony 267
212 tony 307 Respectively, these provide the separator character(s) used to separate fields
213     in data and header rows. Both default to ','.
214 tony 270
215 tony 307 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
216     TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
217     property OnFormatTextString;
218 tony 270
219 tony 307 This event handler can be used to process text strings before they are included
220     in the output e.g. to replace unprintable characters with alternative strings.
221     This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
222 tony 270
223 tony 307 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
224     Uses "FindParam" if in order to find out if a parameter with a given name exists
225     and without raising and exception if it does not.
226 tony 270
227 tony 307 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
228     consistency with SQL queries.
229 tony 270
230 tony 307 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
231     When true, SQL statement parameter names are parsed case sensitive. Note for
232     TIBDataSet only applies to Select query.
233 tony 270
234 tony 307 11. IBEvents: removing a TIBEvent component from a form should no longer result in
235     an IDE exception.
236 tony 270
237 tony 307 12. LocalDBSupport: initial database creation should now work correctly
238     when the schema source is an sql file.
239 tony 270
240 tony 307 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
241     when defined, this handler will be called by the internal TIBXScript during
242     initial database creation when the schema source is an sql file and may be used
243     to provide a visual indication of progress in console mode.
244 tony 270
245 tony 307 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
246     to true while a new local database is being created and its schema populated.
247     Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
248     when the database is disconnected/connected during the create DB procedure.
249 tony 270
250 tony 307 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
251     are now always ignored and replaced by the user name and password provided as
252     the login parameters for the TIBDatabase referenced from the TIBXScript. The
253     IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
254     completely ignored if this property is true.
255 tony 270
256 tony 307 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
257     to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
258     ImageIndex and SelectImageIndex values on AddNode.
259 tony 270
260 tony 307 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
261     read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
262     the same database connection.
263 tony 270
264 tony 307 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
265     if provided, this should be an conditional SQL expression suitable for
266     including in an SQL Select statement "where" clause. If non-empty and the
267     "Filtered" property is true then the SQL expression provided as the value of
268     the "Filter" property is "ANDed" with any existing condition statement
269     in the SQL statement's "Where" clause.
270 tony 270
271 tony 307 If the "Filter" property is set at run time, the "Filtered" property is true
272     and the dataset is already open, then the dataset is closed and re-opened automatically.
273 tony 271
274 tony 307 The "Filter" condition may include IBX style parameters. In which case, their
275     value must be set by the dataset's "OnBeforeOpen" event handler.
276 tony 272
277 tony 307 This is a public property for TIBDataSet and TIBQuery query and intended for
278     use at run time.
279 tony 272
280 tony 307 Note: The property is a published property of TIBTable. The TIBTable functionality
281     is unaffected by this change.
282 tony 272
283 tony 307 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
284 tony 272
285 tony 307 1. Remove need to check for IsMultiThread by providing access to GUI timers via
286     IBGUIInterface. Note: master/detail delay timer does not apply to console
287     mode apps.
288 tony 272
289 tony 307 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
290     statement. This avoids problems if "Execute Block" is used as the Query.
291 tony 272
292 tony 307 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
293     internal SQL tokeniser routines.
294 tony 272
295 tony 307 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
296     as a select statement, with or without CTEs.
297 tony 272
298 tony 307 5. IBSQLParser: parser now recognises the "ROWS" clause.
299 tony 272
300 tony 307 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
301     internal SQL tokeniser routines.
302 tony 272
303 tony 307 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
304     being raised for valid set statements processed by a data formatter.
305 tony 272
306 tony 307 8. New published property for TIBDatabase and TIBXServicesConnection. This is
307     FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
308     the path of the Firebird Library used by the database/services connection.
309 tony 267
310 tony 307 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
311     is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
312     services connection.
313 tony 263
314 tony 307 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
315     or param name is not a valid SQL identifier.
316 tony 263
317 tony 307 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
318     view of whether the text box should be editable when no DataSource is specified.
319     TIBLookupComboEditBox has been updated to workaround this problem. As long as
320     ReadOnly is false, the text box is editable when no DataSource is specified.
321 tony 263
322 tony 307 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
323     the FBLIB environment variable. If you do not want to permit this then you
324     must modify the Register procedure in the design/IBDBReg.pas unit to remove
325     this setting.
326 tony 263
327 tony 307 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
328 tony 263
329 tony 307 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
330     Utf8EscapeControlChars
331 tony 263
332 tony 307 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
333 tony 263
334 tony 307 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
335     all previous copies of the IBX source code tree before installing this release.
336 tony 263
337 tony 307 The IBX packages used by most users have not changed, with one exception. The
338     IBServices unit has been moved to the package iblegacyServices.lpk. To continue
339     to use the IBServices unit in your applications, please add the iblegacyServices
340     to the list of dependencies. To do this, open the Project Inspector and select
341     Add->New Requirement and select "ibLegacyServices" from the list of available
342     packages.
343 tony 263
344 tony 307 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
345     the IBServices unit providing what is intended to be a clearer and easier to
346     use set of IB Services components. See Chapter 10 of the IBX User Guide for
347     more information and the guide to "Firebird Service Management Using IBX".
348     As indicated above, the legacy services components are still available and
349     provided in a separate package. There is no need to update working applications
350     using the older versions except for an additional package dependency.
351 tony 263
352 tony 307 2. The IBX packages and source code tree have been re-organised in an attempt to
353     finally get rid of the "duplicate ppu" warnings. This re-organisation should
354     not affect existing users. Section 2.3 of the IBX User Guide describes the
355     new set of IBX packages.
356 tony 263
357 tony 307 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
358     updated to use the new Services API components.
359 tony 263
360 tony 307 4. The iblocal package has been updated to use the new Services API components.
361 tony 241
362 tony 307 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
363     TIBXSecurityService. It had been wrongly classified in the previous version
364     as a per database configuration item. It is global to a server and hence
365     correctly positioned as part of the Security Package. In the DBAdmin example,
366     the setting has moved to the mappings page.
367 tony 241
368 tony 307 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
369     are ignored.
370 tony 101
371 tony 307 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
372     closed before the database is dropped. Before and After Disconnect event handlers
373     are also fired.
374 tony 209
375 tony 307 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
376     is started and not just the first time.
377 tony 209
378 tony 307 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
379     depenendency with comp type.
380 tony 209
381 tony 307 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
382 tony 209
383 tony 307 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
384     then this is recognised and not ignored.
385 tony 209
386 tony 307 12. TIBDataSet, TIBQuery, TIBTable: additions:
387     function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
388     function GetPerfStatistics(var stats: TPerfCounters): boolean;
389     property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
390 tony 209
391 tony 307 GetRowsAffected returns the affected row counts from the last insert/update/delete
392     if EnableStatistics = true then GetPerfStatistics returns the current stats
393     counters for the select query. Note: stats accumulate after each fetch from
394     the database. To get total query cost after open, call the "Last" method
395     and then GetPerfStatistics.
396 tony 209
397 tony 307 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
398 tony 209
399 tony 307 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
400     in parenthesises.
401 tony 209
402 tony 307 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
403     SQL identifiers are always delimited by double quotes. If false, then they are
404     only delimited if the identifier is a reserved word, contains lower case or special
405     characters. Set this property to true to retain previous behaviour.
406 tony 209
407 tony 307 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
408     are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
409 tony 209
410 tony 307 16. TIBDataSet, TIBQuery, TIBTable: addition:
411     property MasterDetailDelay: integer {defaults to zero}
412 tony 209
413 tony 307 When non-zero and the dataset is a detail table referencing a master table
414     through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
415     then a synchronisation delay is added (in milliseconds) between the master
416     row changing and the detail dataset being re-opened. If the master dataset
417     is scrolled before the delay expires then the delay is reset. This can be used
418     to avoid performance overheads when scrolling through a large master dataset.
419 tony 209
420 tony 307 Note: uses fptimer and hence requires a thread manager. Under Linux the
421     chreads unit must be included in your project. TTimer is not used in order
422     to avoid an LCL dependency. Requires FPC 3.0.2 or later.
423 tony 209
424 tony 307 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
425     with Extract Option eoDatabase.
426 tony 209
427 tony 307 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
428     When a deLayoutChanged event is reported on the ListSource dataset, the
429     combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
430     relationship with the control's datasource (master).
431 tony 209
432 tony 307 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
433 tony 209
434 tony 307 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
435     stubs. Pedantic fix really, as procedures output in dependency order anyway.
436 tony 209
437 tony 307 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
438     DDL (Firebird 3 and later only).
439 tony 209
440 tony 307 22. TIBLookupComboBox Autocomplete Fixes:
441     i. Only appended text is now selected after autocomplete.
442     ii. Uppercase keys no longer ignored for autocomplete.
443     iii. Retain Prefix case is now honoured correctly.
444     iv. When a DataSource is assigned, typing after autocomplete now extends prefix
445     before autocomplete performed. i.e. behaviour now the same as when
446     no DataSource assigned.
447 tony 209
448 tony 307 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
449     between SQL statements.
450 tony 209
451 tony 307 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
452     ObjectNames are converted to upper case before matching against metadata object
453     names, unless the objectname is delimited by double quotes, in which case, the
454     double quotes are removed and the remaining string is used (unmodified) to match
455     against the metadata object name.
456 tony 209
457 tony 307 If true then the ObjectName is used as is without modification and matched
458     against the metadata object name. No attempt is made to remove double quotes.
459 tony 209
460 tony 307 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
461     with eoTrigger, these extract types can be used to select only Database Triggers,
462     or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
463 tony 209
464 tony 307 26. TIBXScript: If an exception occurs during the processing of a statement, the
465     statement separate character is now reset to the default (';').
466 tony 221
467 tony 307 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
468 tony 221
469 tony 307 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
470     a commit or reconnect statement and instead activated only when next SQL statement
471     is executed.
472 tony 221
473 tony 307 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
474 tony 225
475 tony 307 30. TIBXScript: case insensitive regex now used when matching statements instead of
476     converting statement to upper case.
477 tony 225
478 tony 307 31. TIBExtract: metadata comments now supported. New published property
479     IncludeMetaDataComments (default true). If true then metadata comments included
480     in extracted DDL. New Extract Object member eoComments. This may be used with
481     ExtractObject method to list all metadata comments.
482 tony 225
483 tony 307 32. TIBExtract: ListObjectNames method added.
484 tony 225
485 tony 307 33. Updated Database component editor to support additional connection string
486     types.
487 tony 226
488 tony 307 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
489 tony 227
490 tony 307 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
491     AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
492     RELEASE.
493 tony 229
494 tony 307 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
495 tony 229
496 tony 307 1. IBExtract: Identity columns - add additional check for null column for generator name.
497 tony 229
498 tony 307 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
499     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
500     information). However, this is also a very useful mechanism for returning updated computed by
501     column values. Values returned as a result of executing an Insert or Update statement
502     replace existing values in the current row for each corresponding column.
503 tony 229
504 tony 307 Previously, if a dataset's select query included read only (computed by) fields then
505     an automatic row refresh was performed after an insert or update query had been processed,
506     irrespective of the setting of the "ForcedUpdates" property. This has changed such
507     that an automatic refresh is no longer performed if an insert or update query contains
508     a returning clause that updates one or more fields on the current row. A full row
509     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
510     field values and the select query contains read only fields. Use of Insert/update
511     returning should be significantly more efficient than executing a refresh query.
512 tony 229
513 tony 307 This behaviour change is intended to be backwards compatible and there should be no need to change
514     existing programs, other than to improve performance by using the new capability.
515 tony 229
516 tony 307 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
517     they are called when the dataset row is being deleted, there is no value in
518     updating the current record from the query result. Instead, a new event handler
519     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
520     an OnDeleteReturning event handler is provided then it is called with the IResults returned
521     by the query. The event handler can then interrogate the query results and
522     perform whatever action is necessary. For example to confirm, to the user,
523     the deletion of a row with the returned values.
524 tony 231
525 tony 307 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
526     any Computed By or Identity Columns. The IBTables example has been updated to
527     illustrate the computation of the employee Full Name on update.
528 tony 209
529 tony 307 5. TIBTable: The GeneratorField property is now published.
530 tony 151
531 tony 307 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
532     When InsertSQL is generated, the Identity columns are not included in the list of values to
533     be inserted. A RETURNING clause is added to the insert statement to return the value of
534     each Identity column after the insert is executed.
535 tony 151
536 tony 307 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
537     Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
538     Insert..Returning clause.
539 tony 101
540 tony 307 8. TIBGenerator: small performance improvement by not preparing query each time
541     a new value is generated.
542 tony 101
543 tony 307 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
544    
545     10. Property editors will now sync table name to a System Table when "Include System
546     Tables" is selected and the query is for a System Table.
547    
548     11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
549     values are no longer converted to milliseconds from TDateTime and then back again
550     to TDateTime (the conversion to milliseconds is the default TDataset approach).
551    
552     12. Property Editors handling of Stored Procedures.
553     * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
554     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
555     query).
556     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
557    
558     13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
559     can be used to select a package. If non-empty, the stored procedure name is
560     expected to be a stored procedure defined in the specified package and the
561     generated SQL will be as required for a stored procedure located in a package.
562    
563     14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
564     a "Package Name" drop down box to allow selection of a Firebird 3 Package from
565     which a stored procedure can be selected. With no package name selected, non-package
566     stored procedures are listed.
567    
568     15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
569     for password on reconnect.
570    
571     16. TIBDatabase: use IAttachment for connection default character set id, code page
572     and character set name.
573    
574     17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
575     DB info lookups"
576    
577     18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
578    
579     19. Add a property Editor for TIBUpdate.RefreshSQL.
580    
581     20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
582     parameters. This stops an exception being raised when the field cannot be
583     located in the record buffer.
584    
585     21. Property Editors now automatically include System Tables when opened and when the query table
586     is a System Table.
587    
588     22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
589     This avoids errors due to a stale SQRB or SRB being used for the next query.
590    
591     23. IBServices: Service attach parameters now include "expected_db". This is used to
592     add the SPB item isc_spb_expected_db. This names a database using
593     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
594     database. examples/services re-written to illustrate use of "expected_db".
595    
596     24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
597     This avoids truncated backups when the server returns a timeout (busy) response.
598    
599     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
600    
601     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
602     databasenames. These are respectively expanded to the local system's temp directory
603     (including trailing delimiter) or to a prescribed data directory (including
604     trailing delimiter). Under Unix systems the data directory is a hidden directory
605     in the user's home directory. The hidden directory name is either the string returned
606     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
607     Under Windows, the directory is the same as the Data Directory as decribed
608     above but instead prefixed by the User's application data path. These may be
609     used to improve application portability for Personal Databases.
610    
611     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
612     this has not worked for a long time and is not useful either. FieldDefs should be
613     managed using the Fields Editor as with any other dataset. To access the fields
614     editor for a TIBTable component, double click on the component. The fields editor
615     is then displayed.
616    
617     28. TIBDatabaseInfo: new properties/function
618     * DateDBCreated (returns date/time database created)
619     * TransactionCount (returns no. of active transactions)
620     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
621     * PagesFree (Firebird 3 or later)
622     * PagesUsed (Firebird 3 or later)
623     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
624     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
625    
626     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
627    
628     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
629    
630     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
631     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
632    
633     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
634     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
635     firing during backup and restore.
636    
637     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
638     for verbose output using the new property "StatisticsRequested".
639     see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
640    
641     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
642    
643     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
644     palette. This uses the online validation feature added in Firebird 2.5. The
645     services's properties enable inclusion/exclusion of tables and indexes using
646     regular expressions. See.
647     https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
648    
649     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
650     option on a database.
651    
652     37. TIBCustomService: Assign method implemented to allow copying of service login
653     context between service API components. "Detach" method now only detaches
654     service when last reference to the service interface detaches. Tidy up of
655     code for SetActive and Attach methods including password hiding.
656    
657     38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
658     and used to determine the auth method and protocol used for the connection.
659    
660     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
661     a Create Database Statement generated by IBX.
662    
663     40. All IBServices now have an additional published property "PortNo". This may
664     be set to a non-standard port number when necessary. If zero then the default
665     port number is used.
666    
667     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
668     and not just the mouse.
669    
670     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
671    
672     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
673     image index and selected image index for each node to be set from a database field.
674    
675     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
676     then database schema includes grants to all users. If not present then the
677     only user grants included are those to User PUBLIC.
678    
679     45. TIBTreeView: performance improvement. When expanding include both expanded node
680     and child nodes in dataset.
681    
682    
683     IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
684    
685     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
686     changes.
687    
688     2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
689     Bug could result in truncated multi-byte character set values.
690    
691     3. Changes consequential on moving fbintf character set utility functions from
692     IFirebirdAPI to IAttachment.
693    
694     4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
695    
696     5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
697     results in autocomplete ignoring prefix text.
698    
699     6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
700     entering a new name into the text box.
701    
702     7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
703     Firebird rather than recomputing it.
704    
705     8. Property Editor positioning tidy up: All IBX Property editors should now be
706     screen centre. Previously some were "poDesigned" which may be inappropriate
707     for multi monitor desktops.
708    
709     10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
710    
711     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
712     a transaction and always reset the object.
713    
714     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
715    
716     13. TIBXScript: Allow for override of database filename in Create Database statements.
717    
718     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
719     to a gbak format archive.
720    
721     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
722    
723     16. IBLocaldb: Drop database if error creating an empty database.
724    
725     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
726     unless selected node not in current dataset.
727    
728     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
729     to TIBCustomService, and IBlocalDB code tidy up.
730    
731     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
732     behaviour due to uninitialised variable.
733    
734     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
735     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
736    
737     21. IBSQL: When Database changed ensure that all resources are freed.
738    
739     22. IBCustomDataset: When database changed ensure that queries an unprepared.
740    
741     23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
742     * Line Wrap on SQL Token boundaries (on user command)
743     * auto-complete table names in drop down list of table names
744     * Double click on tablename or field name adds to SQL text
745    
746     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
747    
748     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
749     TVariantArray. Seems to avoid memory corruption in Windows (probably a
750     workaround for a problem in fpc 3.0.4 win64).
751    
752     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
753    
754     27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
755    
756     IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
757    
758     1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
759     include remote system name.
760    
761     2. TIBExtract: No longer include comment header and COMMIT statement for empty
762     tables when data included in output.
763    
764     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
765     and timing information to be written to stdout. This may be used to locate
766     performance bottlenecks.
767    
768     4. SQLParser: only call "OnChanging" event handler when value is different.
769    
770     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
771    
772     6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
773     that BindFields is called when the query is next activated. Avoids FieldName
774     not found error.
775    
776     7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
777     purpose and allows the programmer to define any action they want for Update, Insert
778     or Delete. This may be complex SQL (similar to a Trigger), application specific
779     filtering of updates, or use of statements such as Grant or Revoke instead of
780     normal DML. See User Manual for more information.
781    
782     IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
783    
784     1. TIBEvents: Fix uninitialised variable that could result in lost events.
785    
786     2. TIBExtract: Added support for FB3 "USAGE" privilege.
787    
788     3. TIBExtract: data formatted as Charset set "octets" is now output using
789     hexadecimal notation.
790    
791     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
792     using a simple XML format.
793    
794     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
795     grants to these objects.
796    
797     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
798     dependency problems restoring complex databases.
799    
800     7. TIBXScript: This component has been restructured to allow for the processing of
801     embedded XML in INSERT statements and to support interactive sources in addition
802     to non-interactive data sources such as files.
803    
804     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
805    
806     9. TIBXScript: ISQL compatiable Set statements are now supported:
807     SET SQL DIALECT
808     SET TERM
809     SET AUTODDL
810     SET BAIL
811     SET ECHO
812     SET COUNT
813     SET STATS
814     SET NAMES <character set>
815    
816     10. IBVersion unit added to hold current IBX Version Number information.
817    
818     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
819     and domain definitions.
820    
821     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
822     fully supported.
823    
824     13. TIBExtract: when a database dump includes data, the generator values are now also set.
825    
826     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
827    
828     IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
829    
830     See also doc/IBX4LazarusGuide.pdf for important information on
831     upgrading to IBX2.
832    
833     1. Size property of TIBStringField is now the width in characters of the field
834     and not the byte length. This applies only to multi-byte character sets such
835     as UTF8. The original approach aligned with TStringField. However, the TStringField
836     code is not recognised as a bug and hence this change to align the behaviour.
837     The TStringField change is expected in fpc 3.2.0.
838    
839     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
840     true (default) then Size property value saved in the lfm is ignored. Size is
841     always set from the dynamic information read from the database. It is unclear
842     why anyone would want to override this and set Size to false.
843    
844     3. ibxscript: should now handle correctly a Case..End statement within a procedure
845     block.
846    
847     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
848     exist when an attempt is made to connect to it (run time only) then an attempt
849     is made to create the database.
850    
851     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
852     has been successfully created as a result of a call to CreateDatabase or when
853     creating a database after it was found not to exist.
854    
855     6. DBControlGrid: a race condition could result in the wrong row image being
856     written to the cache. This has been avoided by a trip round the message
857     loop before rendering the row image.
858    
859     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
860     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
861     known to risk corrupt rendering of row images when the control is first
862     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
863     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
864    
865     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
866     a TDateEdit control located on an editor panel.
867    
868     9. TIBExtract: brought up-to-date plus many bug fixes.
869    
870     10. DBControlGrid: Removed memory leak when updating rows.
871    
872     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
873    
874     IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
875    
876     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
877     when target codepage is CP_NONE. This is a workaround for
878     http://bugs.freepascal.org/view.php?id=30622.
879    
880     2. DBLog option removed from TIBStatisticalService - not supported by server
881     since Firebird 1.5.
882    
883     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
884     similar.
885    
886     4. IBCodePage: updated mapping between codepages and character id.
887    
888     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
889     Firebird. Character sets with a char width of two are not UTF16.
890    
891     6. Strings received from the database are now always transliterated into UTF8
892     regardless of the database character set or connection character set. This
893     is for compatibility with the LCL.
894    
895     IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
896    
897     1. IBBlob: Defer reading of blob until read method called. This avoids having to
898     read in an entire blob just to get the size of the blob. General performance
899     improvement when opening datasets containing blobs.
900    
901     2. Clearing a Blob now sets the corresponding field's modified flag.
902    
903     3. IBLookupCombo: When not performing auto-complete, original query sort order
904     is now used.
905    
906     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
907     determined.
908    
909     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
910    
911     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
912     lazarus 1.6.0
913    
914     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
915     compilation error.
916    
917     IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
918    
919     1. No character set specified for connection: when a text blob is retrieved, the
920     character set is determined by looking up the native character set using then
921     Firebird API. Otherwise a text mode blob is assumed to have the same character
922     set as the connection.
923    
924     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
925     for Login Dialog returing a change to the database path.
926    
927     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
928     to be changed from that given in the TIBDatabase/TIBServer component and for the
929     entered value to be saved on a project specific basis (design time only).
930    
931     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
932     column fieldname. If they are the same then it is acts as a look up for the KeyValue
933     Otherwise, it sets the column text to the selected ListField Value.
934    
935     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
936     column width.
937    
938     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
939     and a case insensitive search is requested.
940    
941     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
942     or column ListSource.
943    
944     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
945     unprepare) when closing and the text has not changed.
946    
947     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
948     Less likely to cause a cursor re-use error on Windows.
949    
950     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
951     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
952    
953     11. TIBTreeView: Guard against nil destination on record changed
954    
955     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
956     string type with the code page set to reflect the returned field encoding after
957     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
958     earlier versions.
959    
960     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
961     will now result in transliteration to the code page specified for the Firebird driver
962     if the assigned string has a different code page. FPC 3.0.0 onwards only.
963    
964     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
965     is ignored and the lc_ctype value, when the database is opened, is set to align with
966     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
967     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
968     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
969     the GETACP is used to determine the Windows code page.
970    
971     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
972     name used as the lc_ctype when the database was opened. Only valid while the
973     Database is connected.
974    
975     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
976     id that corresponds to the DefaultCharSetName.
977    
978     IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
979    
980     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
981     path is given and database attach fails due to access permission issues on the
982     temp directory or security database, then the attach is retried with "localhost:"
983     prefixing the databasename. This should avoid problems when the database has to
984     be accessed by a local (e.g. classic) server and libfbembed is used.
985    
986     2. Windows: revised search order for Firebird DLL:
987     i. The Firebird Embedded Server in the application Directory.
988     ii. If the FIREBIRD environment variable is set then the directory this
989     points to is searched for the FB Client DLL and then then underlying
990     "bin" directory.
991     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
992     is used to locate the Firebird installation directory and the underlying
993     "bin" directory is searched for the FB Client DLL.
994     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
995     are searched for the FB Client DLL.
996     v. The PATH Environment variable is used to search for the FB Client DLL.
997     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
998    
999     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1000     See doc/readme.scriptengine and example applications.
1001    
1002     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1003     simplify the use of the embedded firebird server on both Linux and Windows platforms.
1004     See dpc/readme.localdatabase and example applications.
1005    
1006     5. IBDynamicGrid: Reordering on column header click should now also work for
1007     dynamic columns.
1008    
1009     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1010     between incrementing/decrementing the lock count and signalling the event.
1011    
1012     IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1013    
1014     1.3.2 was never formally released and only made available as beta copies.
1015    
1016     1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1017    
1018     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1019    
1020     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1021    
1022     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1023     i.e. when it is a calculated field
1024    
1025     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1026     This problem was due to a race condition between recalculating row heights and
1027     determining which row was selected by the mouse click. The row height calculation
1028     is now deferred by an extra trip round the message loop allowing the row to
1029     be always calculated on the current grid layout rather than risking it being
1030     calculated on the grid layout after the expanded row has been shrunk.
1031    
1032     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1033     Windows.
1034    
1035     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1036     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1037     to be determined at runtime. See doc/readme.charactersets.html.
1038    
1039     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1040     TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1041    
1042     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1043     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1044     1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1045    
1046     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1047     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1048     implies no truncation.
1049    
1050     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1051    
1052     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1053     (avoids "Not in Edit Mode" error).
1054    
1055     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1056    
1057     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1058     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1059    
1060     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1061    
1062     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1063    
1064     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1065    
1066     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1067    
1068     IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1069    
1070     1. OnCloseUp Event Handler added to TDBLookupProperties
1071    
1072     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1073     problem with row size when exception is called.
1074    
1075     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1076    
1077     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1078     in a TCustomComboBox and ignores return key if in a TCustomMemo
1079    
1080     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1081     keyed in i.e. when autocomplete not performed
1082    
1083     6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
1084     console mode applications with all LCL required functions (builtin dialogs and
1085     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
1086     not included in your project, IBX should compile and link with a console mode program.
1087     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1088     console mode application or the IDE will automatically assume that your
1089     application is GUI based. Instead, you should include the ibexpressconsolemode package.
1090    
1091     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1092     to use the built in dialogs and cursor management. IBDialogs is
1093     included by default if "ibexpress" is in your project source's "uses" clause.
1094     This should be the case for all projects created through the IDE. This is why
1095     you do not want to add the ibexpress package to console mode applications. The
1096     ibexpressconsolemode package has been created to allow console mode programs
1097     to avoid adding LCL dependencies when using IBX, while still having the
1098     unit search paths set up correctly.
1099    
1100     Existing users should check to ensure that the "ibexpress" unit is included in
1101     each project's source file (*.lpr).
1102    
1103     You may find that in order for the IDE to recognise that ibexpressconsolemode
1104     exists, you have to first open the package in the IDE and then close it. This
1105     adds it to the most recently accessed packages list. To make it permanently
1106     available, add the package name to lazarus' staticpackages.inc file.
1107    
1108     Thanks to Julio Jiménez for suggesting support of console mode.
1109    
1110     7. SQL Parser can now accept quoted strings that include new lines
1111    
1112     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1113     of text on start of edit. This is particularly useful when tabbing to a
1114     column and then inserting text.
1115    
1116     9. New Examples provided for IB Services and ISQLMonitor.
1117    
1118     10. Fix error when writing to blob streams that recorded only the last buffer
1119     write in the blob stream. In most cases, this did not cause a problem as the
1120     IB Blob Stream is written in a single write. However, with the TDBImage, write
1121     of a graphic type prefix was lost which caused a problem when the image could
1122     not be automatically recognised.
1123    
1124     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1125     already open" errors due to random numbers used for the cursor name being identical.
1126    
1127     12. IBTable: corrected error that could result in an "Index out of bounds" error
1128     when opening the table and the Primary Key is the last or only column in the
1129     table. Thanks to Rick Hoover for the fix.
1130    
1131     13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1132     of "UTF-8", and update list of available database character sets. Existing
1133     users should check the current lc_ctype setting in their applications.
1134    
1135     IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1136    
1137     1. Firebird Services: avoid List Index error when opening a service with an
1138     empty Params property.
1139    
1140     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1141     Link now set up in Loaded method - avoids occasional failure to apply
1142     SQL markup on initial open.
1143    
1144     3. "Employees" example performance improvements when scrolling.
1145    
1146     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1147     TFrame. Force recaching of selected frame to avoid GTK race (results in a
1148     random image cached).
1149    
1150     5. DBControlGrid: Should now react to changes in panel height at run time.
1151    
1152     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1153     even when further rows exist.
1154    
1155     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1156     always be derived from panel height and setting this property can cause confusion.
1157     Note for existing projects: to avoid a missing property error at run time,
1158     each form using the DBControlGrid must be opened, updated and saved in the IDE
1159     in order to remove the property value from the lfm.
1160    
1161    
1162     IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1163    
1164     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1165     call Prepare before setting parameter values.
1166    
1167     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1168    
1169     3. Code tidyup and more robust handling of dsql information result vector.
1170    
1171     4. Support for centralised handling of transaction status changes. TIBTransaction
1172     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1173     and "AfterExecQuery". The first three are called after the same event is called
1174     for an IBCustomDataSet descendent using the Transaction. The fourth is called
1175     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1176     enable monitoring of transaction status changes for a given transaction to be
1177     handled in a single place. For example, when a change to the dataset occurs
1178     an indicator can be set that shows the user that in order to save changes,
1179     the transaction should be committed. Rather than doing this per dataset, this
1180     can now be done per transaction.
1181    
1182     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1183     the dataset is scrolled. However, any changes to the current row are, by default,
1184     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1185     have a new property "DataSetCloseAction" that adds automatic posting of changes
1186     on dataset close. If this property is set to dcDiscardChanges (default) then the
1187     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1188     then IBX will attempt to post any unsaved changes before the dataset is closed
1189     (and after the BeforeClose event handler is called). The exception is when the
1190     dataset is being closed as a result of a transaction rollback. In this case,
1191     no action is taken and any unsaved changes are discarded. This avoids both
1192     unnecessary overhead and the risk that a validation error may occur in the Post
1193     raising an exception and thereby preventing a rollback.
1194    
1195     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1196     In earlier versions, the Display Width was set to the maximum byte width rather than the character
1197     width. Display Widths are now corrected by dividing by the max byte width per character.
1198     For UTF8 character sets, the byte width is four and hence the Display Width will be
1199     the byte width divided by 4. The byte width of each character set is determined
1200     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1201     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1202    
1203     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1204    
1205     8. IBLookupComboEditBox: List should now always be restored to full list when the
1206     control loses focus. Default Key press default interval reduced to 200ms.
1207    
1208     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1209     when dataset rows are less than visible rows.
1210    
1211     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1212     does not exist or DataSet is empty. More responsive on dataset open. New event
1213     OnRestorePosition. Column sort disabled if no header row.
1214    
1215     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1216     while dataset state is dsInsert. Avoids posting errors.
1217    
1218     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1219     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1220    
1221     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1222    
1223     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1224     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1225     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1226     always "posts" the current record regardless or whether or not it may be more appropriate
1227     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1228     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1229     as the first action of the "Post" method and allows the handler to convert the Post
1230     into a Cancel if that is the appropriate action on moving to a different row. This is
1231     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1232     raised here, but it may still be more appropriate to validate a post and signal
1233     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1234    
1235     15. On Unix derived systems, the Firebird library name can now be given as a colon
1236     separated list. Each library name on the list is tried in turn, in left to right
1237     order with the first found being used as the firebird library. By default, on Linux,
1238     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1239     overidden by the FBLIB environment variable or the OnGetLibraryName function.
1240    
1241     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1242     then it will still attempt to access the database via the Firebird Server and will
1243     require a username and password. If only the pathname is given, then the username
1244     and password should be omitted and the unix file permissions are used to grant
1245     access.
1246    
1247     IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1248    
1249     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1250     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1251     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1252     corresponds to a row of the linked DataSource. Any data aware control on the
1253     replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1254    
1255     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1256     When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1257     takes place during database access. This may be useful when there are performance issues with
1258     the change of cursor. Setting the property to false suppresses the change of cursor.
1259    
1260     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1261     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1262     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1263     making all changes permanent immediately rather than when the transaction is explicitly
1264     committed.
1265    
1266     4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1267     using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1268    
1269     IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1270    
1271     Development version only.
1272    
1273     IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1274    
1275     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1276     This is typically used during an "OnBeforeOpen" event handler to manipulate the
1277     "Where" and "Having" clauses to implement user specified filters of arbitrary
1278     complexity.
1279    
1280     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1281     three new data aware controls dependent on IBX and which make use of the SQL Parser.
1282     These are:
1283    
1284     - TIBLookupComboEditBox
1285     - TIBDynamicGrid
1286     - TIBTreeview
1287    
1288     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1289     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1290     to revise the available list and restrict it to items that are prefixed by the
1291     typed text (either case sensitive or case insensitive). Autoinsert allows a
1292     newly typed entry to be added to the list dataset and included in the available
1293     list items.
1294    
1295     TIBDynamicGrid is a TDBGrid descendent that provides for:
1296     - automatic resizing of selected columns to fill the available row length
1297     - automatic positioning and sizing of a "totals" control, typically at the
1298     column footer, on a per column basis.
1299     - DataSet resorting on header row click, sorting the dataset by the selected column.
1300     A second click on the same header cell reversed the sort order.
1301     - Support for a "Panel Editor". That is on clicking the indicator column, the row
1302     is automatically expanded and a panel superimposed on it. The panel can have any
1303     number of child controls, typically data aware controls with the same datasource
1304     as the grid allowing for editing of additional fields and more complex editors.
1305     - Reselection of the same row following resorting.
1306     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1307     Its properties are specified on a per column basis and allows for one or more
1308     columns to have their values selected from a list provided by a dataset.
1309     Autocomplete and autoinsert are also available. The existing picklist editor
1310     is unaffected by the extension.
1311    
1312     TIBTreeView is a data aware TCustomTreeView.
1313    
1314     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1315     zero scale will no longer return an error. An Int64 will be returned instead.
1316    
1317     4. TIBTransaction now has events for Before and After Transaction End and a new function
1318     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1319    
1320     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1321     repeated multiple times.
1322    
1323     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1324     check used to get in the way of using Stored Procedures, and "Update or Insert"
1325     statements.
1326    
1327     7. Insert, Modify and Delete property Editors now support Query Generation from
1328     Stored Procedures.
1329    
1330     8. Three new examples illustrate the use of the new IB Controls
1331    
1332    
1333     IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1334    
1335     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1336     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1337     Gabor Boros for reporting this problem and for testing the improvements).
1338    
1339     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1340     See readme.field+param.names in the doc folder.
1341    
1342     3. IBX SQL Editors will now automatically add double quotes around column names when the database
1343     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1344    
1345     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1346    
1347     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1348     actions.
1349    
1350     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1351     thanks to Yuriy Kopnin for pointing this out).
1352    
1353     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1354    
1355     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1356     for both fields and parameter setting.
1357    
1358     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1359     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1360    
1361     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1362     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1363    
1364     11. TIBTable now has a property editor for "MasterFields"
1365    
1366     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1367     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1368    
1369     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1370     of settings is unrecognised. Selecting this radio button has no effect on the settings.
1371

1374    
1375     1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1376    
1377     IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1378    
1379     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1380     it is null. This allows for alternative user defined setting of the generator
1381    
1382     Many thanks to Julio Jiménez for this fix
1383    
1384     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1385     and suggests that the user may have forgotten to install it.
1386    
1387     IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1388    
1389     1. Conditional compilation used to limit registration of TIntegerField to
1390     Lazarus versions less than 1.1
1391    
1392     2. When a database connection is created, character set is now by default set
1393     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1394     1250 to 1254.
1395    
1396    
1397     IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1398    
1399     1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1400    
1401    
1402     IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1403    
1404     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1405     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1406    
1407     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1408     package is changed to do this (which it should do).
1409    
1410     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1411    
1412     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1413    
1414     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1415    
1416     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1417    
1418     4. Property editors should now correctly resize.
1419    
1420     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1421     (restored original functionality)
1422    
1423     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1424     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
