2 >
3 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
4 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
5 > RELEASE.
6 >
7 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
8 >
9 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
10 >
11 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
12 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
13 >   information). However, this is also a very useful mechanism for returning updated computed by
14 >   column values. Values returned as a result of executing an Insert or Update statement
15 >   replace existing values in the current row for each corresponding column.
16 >
17 >   Previously, if a dataset's select query included read only (computed by) fields then
18 >   an automatic row refresh was performed after an insert or update query had been processed,
19 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
20 >   that an automatic refresh is no longer performed if an insert or update query contains
21 >   a returning clause that updates one or more fields on the current row. A full row
22 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
23 >   field values and the select query contains read only fields. Use of Insert/update
24 >   returning should be significantly more efficient than executing a refresh query.
25 >
26 >   This behaviour change is intended to be backwards compatible and there should be no need to change
27 >   existing programs, other than to improve performance by using the new capability.
28 >
29 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
30 >   they are called when the dataset row is being deleted, there is no value in
31 >   updating the current record from the query result. Instead, a new event handler
32 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
33 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
34 >   by the query. The event handler can then interrogate the query results and
35 >   perform whatever action is necessary. For example to confirm, to the user,
36 >   the deletion of a row with the returned values.
37 >
38 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
39 >   any Computed By or Identity Columns. The IBTables example has been updated to
40 >   illustrate the computation of the employee Full Name on update.
41 >
42 > 5. TIBTable: The GeneratorField property is now published.
43 >
44 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
45 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
46 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
47 >   each Identity column after the insert is executed.
48 >
49 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
50 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
51 >   Insert..Returning clause.
52 >
53 > 8. TIBGenerator: small performance improvement by not preparing query each time
54 >   a new value is generated.
55 >
56 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
57 >
58 > 10. Property editors will now sync table name to a System Table when "Include System
59 >    Tables" is selected and the query is for a System Table.
60 >
61 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
62 >    values are no longer converted to milliseconds from TDateTime and then back again
63 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
64 >
65 > 12. Property Editors handling of Stored Procedures.
66 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
67 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
68 >      query).
69 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
70 >
71 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
72 >    can be used to select a package. If non-empty, the stored procedure name is
73 >    expected to be a stored procedure defined in the specified package and the
74 >    generated SQL will be as required for a stored procedure located in a package.
75 >
76 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
77 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
78 >    which a stored procedure can be selected. With no package name selected, non-package
79 >    stored procedures are listed.
80 >
81 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
82 >    for password on reconnect.
83 >
84 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
85 >    and character set name.
86 >
87 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
88 >    DB info lookups"
89 >
90 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
91 >
92 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
93 >
94 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
95 >    parameters. This stops an exception being raised when the field cannot be
96 >    located in the record buffer.
97 >
98 > 21. Property Editors now automatically include System Tables when opened and when the query table
99 >    is a System Table.
100 >
101 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
102 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
103 >
104 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
105 >    add the SPB item isc_spb_expected_db. This names a database using
106 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
107 >    database. examples/services re-written to illustrate use of "expected_db".
108 >
109 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
110 >    This avoids truncated backups when the server returns a timeout (busy) response.
111 >
112 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
113 >
114 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
115 >    databasenames. These are respectively expanded to the local system's temp directory
116 >    (including trailing delimiter) or to a prescribed data directory (including
117 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
118 >    in the user's home directory. The hidden directory name is either the string returned
119 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
120 >    Under Windows, the directory is the same as the Data Directory as decribed
121 >    above but instead prefixed by the User's application data path. These may be
122 >    used to improve application portability for Personal Databases.
123 >
124 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
125 >    this has not worked for a long time and is not useful either. FieldDefs should be
126 >    managed using the Fields Editor as with any other dataset. To access the fields
127 >    editor for a TIBTable component, double click on the component. The fields editor
128 >    is then displayed.
129 >
130 > 28. TIBDatabaseInfo: new properties/function
131 >     * DateDBCreated (returns date/time database created)
132 >     * TransactionCount (returns no. of active transactions)
133 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
134 >     * PagesFree (Firebird 3 or later)
135 >     * PagesUsed (Firebird 3 or later)
136 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
137 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
138 >
139 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
140 >
141 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
142 >
143 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
144 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
145 >
146 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
147 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
148 >    firing during backup and restore.
149 >
150 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
151 >    for verbose output using the new property "StatisticsRequested".
152 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
153 >
154 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
155 >
156 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
157 >    palette. This uses the online validation feature added in Firebird 2.5. The
158 >    services's properties enable inclusion/exclusion of tables and indexes using
159 >    regular expressions. See.
160 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
161 >
162 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
163 >    option on a database.
164 >
165 > 37. TIBCustomService: Assign method implemented to allow copying of service login
166 >    context between service API components. "Detach" method now only detaches
167 >    service when last reference to the service interface detaches. Tidy up of
168 >    code for SetActive and Attach methods including password hiding.
169 >
170 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
171 >    and used to determine the auth method and protocol used for the connection.
172 >
173 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
174 >    a Create Database Statement generated by IBX.
175 >
176 > 40. All IBServices now have an additional published property "PortNo". This may
177 >    be set to a non-standard port number when necessary. If zero then the default
178 >    port number is used.
179 >
180 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
181 >    and not just the mouse.
182 >
183 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
184 >
185 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
186 >    image index and selected image index for each node to be set from a database field.
187 >
188 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
189 >    then database schema includes grants to all users. If not present then the
190 >    only user grants included are those to User PUBLIC.
191 >
192 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
193 >    and child nodes in dataset.
194 >
195 >
196 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
197 >
198 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
199 >   changes.
200 >
201 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
202 >   Bug could result in truncated multi-byte character set values.
203 >
204 > 3. Changes consequential on moving fbintf character set utility functions from
205 >   IFirebirdAPI to IAttachment.
206 >
207 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
208 >
209 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
210 >   results in autocomplete ignoring prefix text.
211 >
212 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
213 >   entering a new name into the text box.
214 >
215 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
216 >   Firebird rather than recomputing it.
217 >
218 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
219 >   screen centre. Previously some were "poDesigned" which may be inappropriate
220 >   for multi monitor desktops.
221 >
222 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
223 >
224 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
225 >    a transaction and always reset the object.
226 >
227 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
228 >
229 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
230 >
231 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
232 >    to a gbak format archive.
233 >
234 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
235 >
236 > 16. IBLocaldb: Drop database if error creating an empty database.
237 >
238 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
239 >    unless selected node not in current dataset.
240 >
241 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
242 >    to TIBCustomService, and IBlocalDB code tidy up.
243 >
244 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
245 >    behaviour due to uninitialised variable.
246 >
247 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
248 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
249 >
250 > 21. IBSQL: When Database changed ensure that all resources are freed.
251 >
252 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
253 >
254 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
255 >    * Line Wrap on SQL Token boundaries (on user command)
256 >    * auto-complete table names in drop down list of table names
257 >    * Double click on tablename or field name adds to SQL text
258 >
259 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
260 >
261 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
262 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
263 >    workaround for a problem in fpc 3.0.4 win64).
264 >
265 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
266 >
267 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
268 >
269 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
270 >
271 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
272 >   include remote system name.
273 >
274 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
275 >   tables when data included in output.
276 >
277 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
278 >   and timing information to be written to stdout. This may be used to locate
279 >   performance bottlenecks.
280 >
281 > 4. SQLParser: only call "OnChanging" event handler when value is different.
282 >
283 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
284 >
285 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
286 >   that BindFields is called when the query is next activated. Avoids FieldName
287 >   not found error.
288 >
289 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
290 >   purpose and allows the programmer to define any action they want for Update, Insert
291 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
292 >   filtering of updates, or use of statements such as Grant or Revoke instead of
293 >   normal DML. See User Manual for more information.
294 >
295 > IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
296 >
297 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
298 >
299 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
300 >
301 > 3. TIBExtract: data formatted as Charset set "octets" is now output using
302 >   hexadecimal notation.
303 >
304 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
305 >   using a simple XML format.
306 >
307 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
308 >   grants to these objects.
309 >
310 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
311 >   dependency problems restoring complex databases.
312 >
313 > 7. TIBXScript: This component has been restructured to allow for the processing of
314 >   embedded XML in INSERT statements and to support interactive sources in addition
315 >   to non-interactive data sources such as files.
316 >
317 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
318 >
319 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
320 >   SET SQL DIALECT
321 >   SET TERM
322 >   SET AUTODDL
323 >   SET BAIL
324 >   SET ECHO
325 >   SET COUNT
326 >   SET STATS
327 >   SET NAMES <character set>
328 >
329 > 10. IBVersion unit added to hold current IBX Version Number information.
330 >
331 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
332 >    and domain definitions.
333 >
334 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
335 >    fully supported.
336 >
337 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
338 >
339 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
340 >
341 > IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
342 >
343 > See also doc/IBX4LazarusGuide.pdf for important information on
344 > upgrading to IBX2.
345 >
346 > 1. Size property of TIBStringField is now the width in characters of the field
347 >   and not the byte length. This applies only to multi-byte character sets such
348 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
349 >   code is not recognised as a bug and hence this change to align the behaviour.
350 >   The TStringField change is expected in fpc 3.2.0.
351 >
352 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
353 >   true (default) then Size property value saved in the lfm is ignored. Size is
354 >   always set from the dynamic information read from the database. It is unclear
355 >   why anyone would want to override this and set Size to false.
356 >
357 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
358 >   block.
359 >
360 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
361 >   exist when an attempt is made to connect to it (run time only) then an attempt
362 >   is made to create the database.
363 >
364 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
365 >   has been successfully created as a result of a call to CreateDatabase or when
366 >   creating a database after it was found not to exist.
367 >
368 > 6.  DBControlGrid: a race condition could result in the wrong row image being
369 >    written to the cache. This has been avoided by a trip round the message
370 >    loop before rendering the row image.
371 >
372 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
373 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
374 >    known to risk corrupt rendering of row images when the control is first
375 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
376 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
377 >
378 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
379 >    a TDateEdit control located on an editor panel.
380 >
381 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
382 >
383 > 10. DBControlGrid: Removed memory leak when updating rows.
384 >
385 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
386 >
387 > IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
388 >
389 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
390 >   when target codepage is CP_NONE. This is a workaround for
391 >   http://bugs.freepascal.org/view.php?id=30622.
392 >
393 > 2. DBLog option removed from TIBStatisticalService - not supported by server
394 >   since Firebird 1.5.
395 >
396 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
397 >   similar.
398 >
399 > 4. IBCodePage: updated mapping between codepages and character id.
400 >
401 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
402 >   Firebird. Character sets with a char width of two are not UTF16.
403 >
404 > 6. Strings received from the database are now always transliterated into UTF8
405 >   regardless of the database character set or connection character set. This
406 >   is for compatibility with the LCL.
407 >
408 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
409 >
410 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
411 >   read in an entire blob just to get the size of the blob. General performance
412 >   improvement when opening datasets containing blobs.
413 >
414 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
415 >
416 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
417 >   is now used.
418 >
419 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
420 >   determined.
421 >
422 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
423 >
424 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post

430 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
431 >
432 > 1. No character set specified for connection: when a text blob is retrieved, the
433 >  character set is determined by looking up the native character set using then
434 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
435 >  set as the connection.
436 >
437 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
438 >   for Login Dialog returing a change to the database path.
439 >
440 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
441 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
442 >   entered value to be saved on a project specific basis (design time only).
443 >
444 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
445 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
446 >   Otherwise, it sets the column text to the selected ListField Value.
447 >
448 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
449 >   column width.
450 >
451 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
452 >   and a case insensitive search is requested.
453 >
454 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
455 >   or column ListSource.
456 >
457 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
458 >   unprepare) when closing and the text has not changed.
459 >
460 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
461 >   Less likely to cause a cursor re-use error on Windows.
462 >
463 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
464 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
465 >
466 > 11. TIBTreeView: Guard against nil destination on record changed
467 >
468 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
469 >    string type with the code page set to reflect the returned field encoding after
470 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
471 >    earlier versions.
472 >
473 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
474 >    will now result in transliteration to the code page specified for the Firebird driver
475 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
476 >
477 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
478 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
479 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
480 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
481 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
482 >    the GETACP is used to determine the Windows code page.
483 >
484 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
485 >    name used as the lc_ctype when the database was opened. Only valid while the
486 >    Database is connected.
487 >
488 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
489 >    id that corresponds to the DefaultCharSetName.

492 >
493 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
494 >   path is given and database attach fails due to access permission issues on the
495 >   temp directory or security database, then the attach is retried with "localhost:"
496 >   prefixing the databasename. This should avoid problems when the database has to
497 >   be accessed by a local (e.g. classic) server and libfbembed is used.
498 >
499 > 2. Windows: revised search order for Firebird DLL:
500 >     i.   The Firebird Embedded Server in the application Directory.
501 >     ii.  If the FIREBIRD environment variable is set then the directory this
502 >          points to is searched for the FB Client DLL and then then underlying
503 >          "bin" directory.
504 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
505 >          is used to locate the Firebird installation directory and the underlying
506 >          "bin" directory is searched for the FB Client DLL.
507 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
508 >          are searched for the FB Client DLL.
509 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
510 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
511 >
512 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
513 >   See doc/readme.scriptengine and example applications.
514 >
515 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
516 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
517 >   See dpc/readme.localdatabase and example applications.
518 >
519 > 5. IBDynamicGrid: Reordering on column header click should now also work for
520 >   dynamic columns.
521 >
522 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
523 >   between incrementing/decrementing the lock count and signalling the event.
524 >
525 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
526 >
527 > 1.3.2 was never formally released and only made available as beta copies.
528 >
529 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
530 >
531 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
532 >
533 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
534 >
535 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
536 >   i.e. when it is a calculated field
537 >
538 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
539 >   This problem was due to a race condition between recalculating row heights and
540 >   determining which row was selected by the mouse click. The row height calculation
541 >   is now deferred by an extra trip round the message loop allowing the row to
542 >   be always calculated on the current grid layout rather than risking it being
543 >   calculated on the grid layout after the expanded row has been shrunk.
544 >
545 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
546 >   Windows.
547 >
548 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
549 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
550 >   to be determined at runtime. See doc/readme.charactersets.html.
551 >
552 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
553 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
554 >
555 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
556 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
557 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
558 >
559 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
560 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
561 >   implies no truncation.
562 >
563 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
564 >
565 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
566 >   (avoids "Not in Edit Mode" error).
567 >
568 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
569 >
570 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
571 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
572 >
573 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
574 >
575 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
576 >
577 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
578 >
579 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
580 >
581 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
582 >
583 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
584 >
585 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
586 >     problem with row size when exception is called.
587 >
588 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
589 >
590 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
591 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
592 >
593 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
594 >     keyed in i.e. when autocomplete not performed
595 >
596 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
597 >     console mode applications with all LCL required functions (builtin dialogs and
598 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
599 >     not included in your project, IBX should compile and link with a console mode program.
600 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
601 >     console mode application or the IDE will automatically assume that your
602 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
603 >
604 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
605 >     to use the built in dialogs and cursor management. IBDialogs is
606 >     included by default if "ibexpress" is in your project source's "uses" clause.
607 >     This should be the case for all projects created through the IDE. This is why
608 >     you do not want to add the ibexpress package to console mode applications. The
609 >     ibexpressconsolemode package has been created to allow console mode programs
610 >     to avoid adding LCL dependencies when using IBX, while still having the
611 >     unit search paths set up correctly.
612 >
613 >     Existing users should check to ensure that the "ibexpress" unit is included in
614 >     each project's source file (*.lpr).
615 >
616 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
617 >     exists, you have to first open the package in the IDE and then close it. This
618 >     adds it to the most recently accessed packages list. To make it permanently
619 >     available, add the package name to lazarus' staticpackages.inc file.
620 >
621 >         Thanks to Julio Jiménez for suggesting support of console mode.
622 >
623 > 7.   SQL Parser can now accept quoted strings that include new lines
624 >
625 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
626 >     of text on start of edit. This is particularly useful when tabbing to a
627 >     column and then inserting text.
628 >
629 > 9.   New Examples provided for IB Services and ISQLMonitor.
630 >
631 > 10. Fix error when writing to blob streams that recorded only the last buffer
632 >    write in the blob stream. In most cases, this did not cause a problem as the
633 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
634 >    of a graphic type prefix was lost which caused a problem when the image could
635 >        not be automatically recognised.
636 >
637 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
638 >    already open" errors due to random numbers used for the cursor name being identical.
639 >
640 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
641 >    when opening the table and the Primary Key is the last or only column in the
642 >    table. Thanks to Rick Hoover for the fix.
643 >
644 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
645 >    of "UTF-8", and update list of available database character sets. Existing
646 >    users should check the current lc_ctype setting in their applications.
647 >
648 > IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
649 >
650 > 1.  Firebird Services: avoid List Index error when opening a service with an
651 >    empty Params property.
652 >
653 > 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
654 >    Link now set up in Loaded method - avoids occasional failure to apply
655 >    SQL markup on initial open.
656 >
657 > 3.  "Employees" example performance improvements when scrolling.
658 >
659 > 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
660 >    TFrame. Force recaching of selected frame to avoid GTK race (results in a
661 >    random image cached).
662 >
663 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
664 >
665 > 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
666 >    even when further rows exist.
667 >
668 > 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
669 >    always be derived from panel height and setting this property can cause confusion.
670 >    Note for existing projects: to avoid a missing property error at run time,
671 >    each form using the DBControlGrid must be opened, updated and saved in the IDE
672 >    in order to remove the property value from the lfm.
673 >
674 >
675 > IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
676 >
677 > 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
678 >    call Prepare before setting parameter values.
679 >
680 > 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
681 >
682 > 3.  Code tidyup and more robust handling of dsql information result vector.
683 >
684 > 4.  Support for centralised handling of transaction status changes. TIBTransaction
685 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
686 >    and "AfterExecQuery". The first three are called after the same event is called
687 >    for an IBCustomDataSet descendent using the Transaction. The fourth is called
688 >    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
689 >    enable monitoring of transaction status changes for a given transaction to be
690 >    handled in a single place. For example, when a change to the dataset occurs
691 >    an indicator can be set that shows the user that in order to save changes,
692 >    the transaction should be committed.  Rather than doing this per dataset, this
693 >    can now be done per transaction.
694 >
695 > 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
696 >    the dataset is scrolled. However, any changes to the current row are, by default,
697 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
698 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
699 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
700 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
701 >    then IBX will attempt to post any unsaved changes before the dataset is closed
702 >    (and after the BeforeClose event handler is called). The exception is when the
703 >    dataset is being closed as a result of a transaction rollback. In this case,
704 >    no action is taken and any unsaved  changes are discarded. This avoids both
705 >    unnecessary overhead and the risk that a validation error may occur in the Post
706 >    raising an exception and thereby preventing a rollback.
707 >
708 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
709 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
710 >    width. Display Widths are now corrected by dividing by the max byte width per character.
711 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
712 >    the byte width divided by 4. The byte width of each character set is determined
713 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
714 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
715 >
716 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
717 >
718 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
719 >    control loses focus. Default Key press default interval reduced to 200ms.
720 >
721 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
722 >    when dataset rows are less than visible rows.
723 >
724 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
725 >    does not exist or DataSet is empty. More responsive on dataset open. New event
726 >    OnRestorePosition. Column sort disabled if no header row.
727 >
728 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
729 >    while dataset state is dsInsert. Avoids posting errors.
730 >
731 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
732 >    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
733 >
734 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
735 >
736 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
737 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
738 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
739 >    always "posts" the current record regardless or whether or not it may be more appropriate
740 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
741 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
742 >    as the first action of the "Post" method and allows the handler to convert the Post
743 >    into a Cancel if that is the appropriate action on moving to a different row. This is
744 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
745 >    raised here, but it may still be more appropriate to validate a post and signal
746 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
747 >
748 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
749 >    separated list. Each library name on the list is tried in turn, in left to right
750 >    order with the first found being used as the firebird library. By default, on Linux,
751 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
752 >    overidden by the FBLIB environment variable or the OnGetLibraryName function.
753 >
754 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
755 >    then it will still attempt to access the database via the Firebird Server and will
756 >    require a username and password. If only the pathname is given, then the username
757 >    and password should be omitted and the unix file permissions are used to grant
758 >    access.

760 > IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
761 >
762 > 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
763 >    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
764 >    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
765 >    corresponds to a row of the linked DataSource. Any data aware control on the
766 >    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
767 >
768 > 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
769 >   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
770 >   takes place during database access. This may be useful when there are performance issues with
771 >   the change of cursor. Setting the property to false suppresses the change of cursor.
772 >
773 > 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
774 >   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
775 >   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
776 >   making all changes permanent immediately rather than when the transaction is explicitly
777 >   committed.
778 >
779 > 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
780 >   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

787 >
788 > 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
789 >   This is typically used during an "OnBeforeOpen" event handler to manipulate the
790 >   "Where" and "Having" clauses to implement user specified filters of arbitrary
791 >   complexity.
792 >
793 > 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
794 >   three new data aware controls dependent on IBX and which make use of the SQL Parser.
795 >   These are:
796 >
797 >   - TIBLookupComboEditBox
798 >   - TIBDynamicGrid
799 >   - TIBTreeview
800 >
801 >   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
802 >   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
803 >   to revise the available list and restrict it to items that are prefixed by the
804 >   typed text (either case sensitive or case insensitive). Autoinsert allows a
805 >   newly typed entry to be added to the list dataset and included in the available
806 >   list items.
807 >
808 >   TIBDynamicGrid is a TDBGrid descendent that provides for:
809 >   - automatic resizing of selected columns to fill the available row length
810 >   - automatic positioning and sizing of a "totals" control, typically at the
811 >     column footer, on a per column basis.
812 >   - DataSet resorting on header row click, sorting the dataset by the selected column.
813 >     A second click on the same header cell reversed the sort order.
814 >   - Support for a "Panel Editor". That is on clicking the indicator column, the row
815 >     is automatically expanded and a panel superimposed on it. The panel can have any
816 >     number of child controls, typically data aware controls with the same datasource
