2 >
3 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
4 > all previous copies of the IBX source code tree before installing this release.
5 >
6 > The IBX packages used by most users have not changed, with one exception. The
7 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
8 > to use the IBServices unit in your applications, please add the iblegacyServices
9 > to the list of dependencies. To do this, open the Project Inspector and select
10 > Add->New Requirement and select "ibLegacyServices" from the list of available
11 > packages.
12 >
13 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
14 >   the IBServices unit providing what is intended to be a clearer and easier to
15 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
16 >   more information and the guide to "Firebird Service Management Using IBX".
17 >   As indicated above, the legacy services components are still available and
18 >   provided in a separate package. There is no need to update working applications
19 >   using the older versions except for an additional package dependency.
20 >
21 > 2. The IBX packages and source code tree have been re-organised in an attempt to
22 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
23 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
24 >   new set of IBX packages.
25 >
26 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
27 >   updated to use the new Services API components.
28 >
29 > 4. The iblocal package has been updated to use the new Services API components.
30 >
31 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
32 >   TIBXSecurityService. It had been wrongly classified in the previous version
33 >   as a per database configuration item. It is global to a server and hence
34 >   correctly positioned as part of the Security Package. In the DBAdmin example,
35 >   the setting has moved to the mappings page.
36 >
37 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
38 >   are ignored.
39 >
40 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
41 >   closed before the database is dropped. Before and After Disconnect event handlers
42 >   are also fired.
43 >
44 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
45 >   is started and not just the first time.
46 >
47 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
48 >   depenendency with comp type.
49 >
50 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
51 >
52 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
53 >    then this is recognised and not ignored.
54 >
55 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
56 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
57 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
58 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
59 >
60 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
61 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
62 >    counters for the select query. Note: stats accumulate after each fetch from
63 >    the database. To get total query cost after open, call the "Last" method
64 >    and then GetPerfStatistics.
65 >
66 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
67 >
68 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
69 >    in parenthesises.
70 >
71 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
72 >    SQL identifiers are always delimited by double quotes. If false, then they are
73 >    only delimited if the identifier is a reserved word, contains lower case or special
74 >    characters. Set this property to true to retain previous behaviour.
75 >
76 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
77 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
78 >
79 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
80 >       property MasterDetailDelay: integer {defaults to zero}
81 >
82 >    When non-zero and the dataset is a detail table referencing a master table
83 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
84 >    then a synchronisation delay is added (in milliseconds) between the master
85 >    row changing and the detail dataset being re-opened. If the master dataset
86 >    is scrolled before the delay expires then the delay is reset. This can be used
87 >    to avoid performance overheads when scrolling through a large master dataset.
88 >
89 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
90 >    chreads unit must be included in your project. TTimer is not used in order
91 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
92 >
93 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
94 >    with Extract Option eoDatabase.
95 >
96 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
97 >    When a deLayoutChanged event is reported on the ListSource dataset, the
98 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
99 >    relationship with the control's datasource (master).
100 >
101 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
102 >
103 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
104 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
105 >
106 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
107 >    DDL (Firebird 3 and later only).
108 >
109 > 22. TIBLookupComboBox Autocomplete Fixes:
110 >    i. Only appended text is now selected after autocomplete.
111 >    ii. Uppercase keys no longer ignored for autocomplete.
112 >    iii. Retain Prefix case is now honoured correctly.
113 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
114 >        before autocomplete performed. i.e. behaviour now the same as when
115 >        no DataSource assigned.
116 >
117 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
118 >    between SQL statements.
119 >
120 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
121 >    ObjectNames are converted to upper case before matching against metadata object
122 >    names, unless the objectname is delimited by double quotes, in which case, the
123 >    double quotes are removed and the remaining string is used (unmodified) to match
124 >    against the metadata object name.
125 >
126 >    If true then the ObjectName is used as is without modification and matched
127 >    against the metadata object name. No attempt is made to remove double quotes.
128 >
129 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
130 >    with eoTrigger, these extract types can be used to select only Database Triggers,
131 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
132 >
133 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
134 >
135 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
136 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
137 > RELEASE.
138 >
139 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
140 >
141 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
142 >
143 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
144 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
145 >   information). However, this is also a very useful mechanism for returning updated computed by
146 >   column values. Values returned as a result of executing an Insert or Update statement
147 >   replace existing values in the current row for each corresponding column.
148 >
149 >   Previously, if a dataset's select query included read only (computed by) fields then
150 >   an automatic row refresh was performed after an insert or update query had been processed,
151 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
152 >   that an automatic refresh is no longer performed if an insert or update query contains
153 >   a returning clause that updates one or more fields on the current row. A full row
154 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
155 >   field values and the select query contains read only fields. Use of Insert/update
156 >   returning should be significantly more efficient than executing a refresh query.
157 >
158 >   This behaviour change is intended to be backwards compatible and there should be no need to change
159 >   existing programs, other than to improve performance by using the new capability.
160 >
161 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
162 >   they are called when the dataset row is being deleted, there is no value in
163 >   updating the current record from the query result. Instead, a new event handler
164 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
165 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
166 >   by the query. The event handler can then interrogate the query results and
167 >   perform whatever action is necessary. For example to confirm, to the user,
168 >   the deletion of a row with the returned values.
169 >
170 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
171 >   any Computed By or Identity Columns. The IBTables example has been updated to
172 >   illustrate the computation of the employee Full Name on update.
173 >
174 > 5. TIBTable: The GeneratorField property is now published.
175 >
176 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
177 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
178 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
179 >   each Identity column after the insert is executed.
180 >
181 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
182 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
183 >   Insert..Returning clause.
184 >
185 > 8. TIBGenerator: small performance improvement by not preparing query each time
186 >   a new value is generated.
187 >
188 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
189 >
190 > 10. Property editors will now sync table name to a System Table when "Include System
191 >    Tables" is selected and the query is for a System Table.
192 >
193 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
194 >    values are no longer converted to milliseconds from TDateTime and then back again
195 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
196 >
197 > 12. Property Editors handling of Stored Procedures.
198 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
199 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
200 >      query).
201 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
202 >
203 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
204 >    can be used to select a package. If non-empty, the stored procedure name is
205 >    expected to be a stored procedure defined in the specified package and the
206 >    generated SQL will be as required for a stored procedure located in a package.
207 >
208 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
209 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
210 >    which a stored procedure can be selected. With no package name selected, non-package
211 >    stored procedures are listed.
212 >
213 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
214 >    for password on reconnect.
215 >
216 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
217 >    and character set name.
218 >
219 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
220 >    DB info lookups"
221 >
222 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
223 >
224 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
225 >
226 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
227 >    parameters. This stops an exception being raised when the field cannot be
228 >    located in the record buffer.
229 >
230 > 21. Property Editors now automatically include System Tables when opened and when the query table
231 >    is a System Table.
232 >
233 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
234 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
235 >
236 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
237 >    add the SPB item isc_spb_expected_db. This names a database using
238 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
239 >    database. examples/services re-written to illustrate use of "expected_db".
240 >
241 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
242 >    This avoids truncated backups when the server returns a timeout (busy) response.
243 >
244 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
245 >
246 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
247 >    databasenames. These are respectively expanded to the local system's temp directory
248 >    (including trailing delimiter) or to a prescribed data directory (including
249 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
250 >    in the user's home directory. The hidden directory name is either the string returned
251 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
252 >    Under Windows, the directory is the same as the Data Directory as decribed
253 >    above but instead prefixed by the User's application data path. These may be
254 >    used to improve application portability for Personal Databases.
255 >
256 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
257 >    this has not worked for a long time and is not useful either. FieldDefs should be
258 >    managed using the Fields Editor as with any other dataset. To access the fields
259 >    editor for a TIBTable component, double click on the component. The fields editor
260 >    is then displayed.
261 >
262 > 28. TIBDatabaseInfo: new properties/function
263 >     * DateDBCreated (returns date/time database created)
264 >     * TransactionCount (returns no. of active transactions)
265 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
266 >     * PagesFree (Firebird 3 or later)
267 >     * PagesUsed (Firebird 3 or later)
268 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
269 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
270 >
271 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
272 >
273 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
274 >
275 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
276 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
277 >
278 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
279 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
280 >    firing during backup and restore.
281 >
282 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
283 >    for verbose output using the new property "StatisticsRequested".
284 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
285 >
286 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
287 >
288 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
289 >    palette. This uses the online validation feature added in Firebird 2.5. The
290 >    services's properties enable inclusion/exclusion of tables and indexes using
291 >    regular expressions. See.
292 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
293 >
294 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
295 >    option on a database.
296 >
297 > 37. TIBCustomService: Assign method implemented to allow copying of service login
298 >    context between service API components. "Detach" method now only detaches
299 >    service when last reference to the service interface detaches. Tidy up of
300 >    code for SetActive and Attach methods including password hiding.
301 >
302 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
303 >    and used to determine the auth method and protocol used for the connection.
304 >
305 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
306 >    a Create Database Statement generated by IBX.
307 >
308 > 40. All IBServices now have an additional published property "PortNo". This may
309 >    be set to a non-standard port number when necessary. If zero then the default
310 >    port number is used.
311 >
312 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
313 >    and not just the mouse.
314 >
315 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
316 >
317 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
318 >    image index and selected image index for each node to be set from a database field.
319 >
320 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
321 >    then database schema includes grants to all users. If not present then the
322 >    only user grants included are those to User PUBLIC.
323 >
324 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
325 >    and child nodes in dataset.
326 >
327 >
328 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
329 >
330 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
331 >   changes.
332 >
333 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
334 >   Bug could result in truncated multi-byte character set values.
335 >
336 > 3. Changes consequential on moving fbintf character set utility functions from
337 >   IFirebirdAPI to IAttachment.
338 >
339 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
340 >
341 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
342 >   results in autocomplete ignoring prefix text.
343 >
344 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
345 >   entering a new name into the text box.
346 >
347 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
348 >   Firebird rather than recomputing it.
349 >
350 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
351 >   screen centre. Previously some were "poDesigned" which may be inappropriate
352 >   for multi monitor desktops.
353 >
354 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
355 >
356 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
357 >    a transaction and always reset the object.
358 >
359 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
360 >
361 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
362 >
363 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
364 >    to a gbak format archive.
365 >
366 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
367 >
368 > 16. IBLocaldb: Drop database if error creating an empty database.
369 >
370 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
371 >    unless selected node not in current dataset.
372 >
373 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
374 >    to TIBCustomService, and IBlocalDB code tidy up.
375 >
376 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
377 >    behaviour due to uninitialised variable.
378 >
379 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
380 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
381 >
382 > 21. IBSQL: When Database changed ensure that all resources are freed.
383 >
384 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
385 >
386 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
387 >    * Line Wrap on SQL Token boundaries (on user command)
388 >    * auto-complete table names in drop down list of table names
389 >    * Double click on tablename or field name adds to SQL text
390 >
391 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
392 >
393 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
394 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
395 >    workaround for a problem in fpc 3.0.4 win64).
396 >
397 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
398 >
399 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
400 >
401 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
402 >
403 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
404 >   include remote system name.
405 >
406 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
407 >   tables when data included in output.
408 >
409 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
410 >   and timing information to be written to stdout. This may be used to locate
411 >   performance bottlenecks.
412 >
413 > 4. SQLParser: only call "OnChanging" event handler when value is different.
414 >

428 >
429 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
430 >
431 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
432 >
433 > 3. TIBExtract: data formatted as Charset set "octets" is now output using
434 >   hexadecimal notation.
435 >
436 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
437 >   using a simple XML format.
438 >
439 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
440 >   grants to these objects.
441 >
442 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
443 >   dependency problems restoring complex databases.
444 >
445 > 7. TIBXScript: This component has been restructured to allow for the processing of
446 >   embedded XML in INSERT statements and to support interactive sources in addition
447 >   to non-interactive data sources such as files.
448 >
449 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
450 >
451 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
452 >   SET SQL DIALECT
453 >   SET TERM
454 >   SET AUTODDL
455 >   SET BAIL
456 >   SET ECHO
457 >   SET COUNT
458 >   SET STATS
459 >   SET NAMES <character set>
460 >
461 > 10. IBVersion unit added to hold current IBX Version Number information.
462 >
463 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
464 >    and domain definitions.
465 >
466 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
467 >    fully supported.
468 >
469 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
470 >
471 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.

474 >
475 > See also doc/IBX4LazarusGuide.pdf for important information on
476 > upgrading to IBX2.
477 >
478 > 1. Size property of TIBStringField is now the width in characters of the field
479 >   and not the byte length. This applies only to multi-byte character sets such
480 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
481 >   code is not recognised as a bug and hence this change to align the behaviour.
482 >   The TStringField change is expected in fpc 3.2.0.
483 >
484 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
485 >   true (default) then Size property value saved in the lfm is ignored. Size is
486 >   always set from the dynamic information read from the database. It is unclear
487 >   why anyone would want to override this and set Size to false.
488 >
489 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
490 >   block.
491 >
492 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
493 >   exist when an attempt is made to connect to it (run time only) then an attempt
494 >   is made to create the database.
495 >
496 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
497 >   has been successfully created as a result of a call to CreateDatabase or when
498 >   creating a database after it was found not to exist.
499 >
500 > 6.  DBControlGrid: a race condition could result in the wrong row image being
501 >    written to the cache. This has been avoided by a trip round the message
502 >    loop before rendering the row image.
503 >
504 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
505 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
506 >    known to risk corrupt rendering of row images when the control is first
507 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
508 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
509 >
510 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
511 >    a TDateEdit control located on an editor panel.
512 >
513 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
514 >
515 > 10. DBControlGrid: Removed memory leak when updating rows.
516 >
517 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

520 >
521 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
522 >   when target codepage is CP_NONE. This is a workaround for
523 >   http://bugs.freepascal.org/view.php?id=30622.
524 >
525 > 2. DBLog option removed from TIBStatisticalService - not supported by server
526 >   since Firebird 1.5.
527 >
528 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
529 >   similar.
530 >
531 > 4. IBCodePage: updated mapping between codepages and character id.
532 >
533 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
534 >   Firebird. Character sets with a char width of two are not UTF16.
535 >
536 > 6. Strings received from the database are now always transliterated into UTF8
537 >   regardless of the database character set or connection character set. This
538 >   is for compatibility with the LCL.
539 >
540 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
541 >
542 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
543 >   read in an entire blob just to get the size of the blob. General performance
544 >   improvement when opening datasets containing blobs.
545 >
546 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
547 >
548 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
549 >   is now used.
550 >
551 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
552 >   determined.
553 >
554 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
555 >
556 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
557 >   lazarus 1.6.0
558 >
559 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
560 >   compilation error.

563 >
564 > 1. No character set specified for connection: when a text blob is retrieved, the
565 >  character set is determined by looking up the native character set using then
566 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
567 >  set as the connection.
568 >
569 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
570 >   for Login Dialog returing a change to the database path.
571 >
572 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
573 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
574 >   entered value to be saved on a project specific basis (design time only).
575 >
576 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
577 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
578 >   Otherwise, it sets the column text to the selected ListField Value.
579 >
580 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
581 >   column width.
582 >
583 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
584 >   and a case insensitive search is requested.
585 >
586 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
587 >   or column ListSource.
588 >
589 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
590 >   unprepare) when closing and the text has not changed.
591 >
592 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
593 >   Less likely to cause a cursor re-use error on Windows.
594 >
595 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
596 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
597 >
598 > 11. TIBTreeView: Guard against nil destination on record changed
599 >
600 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
601 >    string type with the code page set to reflect the returned field encoding after
602 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
603 >    earlier versions.
604 >
605 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
606 >    will now result in transliteration to the code page specified for the Firebird driver
607 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
608 >
609 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
610 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
611 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
612 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
613 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
614 >    the GETACP is used to determine the Windows code page.
615 >
616 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
617 >    name used as the lc_ctype when the database was opened. Only valid while the
618 >    Database is connected.
619 >
620 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
621 >    id that corresponds to the DefaultCharSetName.

624 >
625 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
626 >   path is given and database attach fails due to access permission issues on the
627 >   temp directory or security database, then the attach is retried with "localhost:"
628 >   prefixing the databasename. This should avoid problems when the database has to
629 >   be accessed by a local (e.g. classic) server and libfbembed is used.
630 >
631 > 2. Windows: revised search order for Firebird DLL:
632 >     i.   The Firebird Embedded Server in the application Directory.
633 >     ii.  If the FIREBIRD environment variable is set then the directory this
634 >          points to is searched for the FB Client DLL and then then underlying
635 >          "bin" directory.
636 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
637 >          is used to locate the Firebird installation directory and the underlying
638 >          "bin" directory is searched for the FB Client DLL.
639 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
640 >          are searched for the FB Client DLL.
641 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
642 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
643 >
644 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
645 >   See doc/readme.scriptengine and example applications.
646 >
647 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
648 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
649 >   See dpc/readme.localdatabase and example applications.
650 >
651 > 5. IBDynamicGrid: Reordering on column header click should now also work for
652 >   dynamic columns.
653 >
654 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
655 >   between incrementing/decrementing the lock count and signalling the event.

658 >
659 > 1.3.2 was never formally released and only made available as beta copies.
660 >
661 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
662 >
663 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
664 >
665 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
666 >
667 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
668 >   i.e. when it is a calculated field
669 >
670 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
671 >   This problem was due to a race condition between recalculating row heights and
672 >   determining which row was selected by the mouse click. The row height calculation
673 >   is now deferred by an extra trip round the message loop allowing the row to
674 >   be always calculated on the current grid layout rather than risking it being
675 >   calculated on the grid layout after the expanded row has been shrunk.
676 >
677 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
678 >   Windows.
679 >
680 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
681 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
682 >   to be determined at runtime. See doc/readme.charactersets.html.
683 >
684 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
685 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
686 >
687 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
688 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
689 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
690 >
691 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
692 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
693 >   implies no truncation.
694 >
695 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
696 >
697 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
698 >   (avoids "Not in Edit Mode" error).
699 >
700 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
701 >
702 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
703 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
704 >
705 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
706 >
707 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
708 >
709 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
710 >
711 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
712 >
713 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
714 >
715 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
716 >
717 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
718 >     problem with row size when exception is called.
719 >
720 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
721 >
722 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
723 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
724 >
725 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
726 >     keyed in i.e. when autocomplete not performed
727 >
728 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
729 >     console mode applications with all LCL required functions (builtin dialogs and
730 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
731 >     not included in your project, IBX should compile and link with a console mode program.
732 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
733 >     console mode application or the IDE will automatically assume that your
734 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
735 >
736 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
737 >     to use the built in dialogs and cursor management. IBDialogs is
738 >     included by default if "ibexpress" is in your project source's "uses" clause.
739 >     This should be the case for all projects created through the IDE. This is why
740 >     you do not want to add the ibexpress package to console mode applications. The
741 >     ibexpressconsolemode package has been created to allow console mode programs
742 >     to avoid adding LCL dependencies when using IBX, while still having the
743 >     unit search paths set up correctly.
744 >
745 >     Existing users should check to ensure that the "ibexpress" unit is included in
746 >     each project's source file (*.lpr).
747 >
748 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
749 >     exists, you have to first open the package in the IDE and then close it. This
750 >     adds it to the most recently accessed packages list. To make it permanently
751 >     available, add the package name to lazarus' staticpackages.inc file.
752 >
753 >         Thanks to Julio Jiménez for suggesting support of console mode.
754 >
755 > 7.   SQL Parser can now accept quoted strings that include new lines
756 >
757 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
758 >     of text on start of edit. This is particularly useful when tabbing to a
759 >     column and then inserting text.
760 >
761 > 9.   New Examples provided for IB Services and ISQLMonitor.
762 >
763 > 10. Fix error when writing to blob streams that recorded only the last buffer
764 >    write in the blob stream. In most cases, this did not cause a problem as the
765 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
766 >    of a graphic type prefix was lost which caused a problem when the image could
767 >        not be automatically recognised.
768 >
769 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
770 >    already open" errors due to random numbers used for the cursor name being identical.
771 >
772 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
773 >    when opening the table and the Primary Key is the last or only column in the
774 >    table. Thanks to Rick Hoover for the fix.
775 >
776 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
777 >    of "UTF-8", and update list of available database character sets. Existing
778 >    users should check the current lc_ctype setting in their applications.

781 >
782 > 1.  Firebird Services: avoid List Index error when opening a service with an
783 >    empty Params property.
784 >
785 > 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
786 >    Link now set up in Loaded method - avoids occasional failure to apply
787 >    SQL markup on initial open.
788 >
789 > 3.  "Employees" example performance improvements when scrolling.
790 >
791 > 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
792 >    TFrame. Force recaching of selected frame to avoid GTK race (results in a
793 >    random image cached).
794 >
795 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
796 >
797 > 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
798 >    even when further rows exist.
799 >
800 > 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
801 >    always be derived from panel height and setting this property can cause confusion.
802 >    Note for existing projects: to avoid a missing property error at run time,
803 >    each form using the DBControlGrid must be opened, updated and saved in the IDE
804 >    in order to remove the property value from the lfm.

807 > IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
808 >
809 > 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
810 >    call Prepare before setting parameter values.
811 >
812 > 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
813 >
814 > 3.  Code tidyup and more robust handling of dsql information result vector.
815 >
816 > 4.  Support for centralised handling of transaction status changes. TIBTransaction
817 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
818 >    and "AfterExecQuery". The first three are called after the same event is called
819 >    for an IBCustomDataSet descendent using the Transaction. The fourth is called
820 >    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
821 >    enable monitoring of transaction status changes for a given transaction to be
822 >    handled in a single place. For example, when a change to the dataset occurs
823 >    an indicator can be set that shows the user that in order to save changes,
824 >    the transaction should be committed.  Rather than doing this per dataset, this
825 >    can now be done per transaction.
826 >
827 > 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
828 >    the dataset is scrolled. However, any changes to the current row are, by default,
829 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
830 >    have a new property "DataSetCloseAction" that adds automatic posting of changes

848 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.

850 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
851 >    control loses focus. Default Key press default interval reduced to 200ms.
852 >
853 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
854 >    when dataset rows are less than visible rows.
855 >
856 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
857 >    does not exist or DataSet is empty. More responsive on dataset open. New event
858 >    OnRestorePosition. Column sort disabled if no header row.
859 >
860 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
861 >    while dataset state is dsInsert. Avoids posting errors.

863 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
864 >    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
865 >
866 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
867 >
868 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
869 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
870 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
871 >    always "posts" the current record regardless or whether or not it may be more appropriate
872 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
873 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
874 >    as the first action of the "Post" method and allows the handler to convert the Post
875 >    into a Cancel if that is the appropriate action on moving to a different row. This is
876 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
877 >    raised here, but it may still be more appropriate to validate a post and signal
878 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
879 >
880 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
881 >    separated list. Each library name on the list is tried in turn, in left to right
882 >    order with the first found being used as the firebird library. By default, on Linux,
883 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
884 >    overidden by the FBLIB environment variable or the OnGetLibraryName function.
885 >
886 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
887 >    then it will still attempt to access the database via the Firebird Server and will
888 >    require a username and password. If only the pathname is given, then the username
889 >    and password should be omitted and the unix file permissions are used to grant
890 >    access.

894 > 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
895 >    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
896 >    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
897 >    corresponds to a row of the linked DataSource. Any data aware control on the
898 >    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
899 >
900 > 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
901 >   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
902 >   takes place during database access. This may be useful when there are performance issues with
903 >   the change of cursor. Setting the property to false suppresses the change of cursor.
904 >
905 > 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
906 >   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
907 >   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
908 >   making all changes permanent immediately rather than when the transaction is explicitly
909 >   committed.
910 >
911 > 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
912 >   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

920   1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
921     This is typically used during an "OnBeforeOpen" event handler to manipulate the
# Line 16 | Line 933 | IBX Change Log  version
933     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
934     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
935     to revise the available list and restrict it to items that are prefixed by the
936 <   typed text (either case sensitive or case insenstive). Autoinsert allows a
936 >   typed text (either case sensitive or case insensitive). Autoinsert allows a
937     newly typed entry to be added to the list dataset and included in the available
938     list items.
