1 + IBX Change Log  version                   (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
2 +
3 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
4 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
5 +   mode apps.
6 +
7 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
8 +   statement. This avoids problems if "Execute Block" is used as the Query.
9 +
10 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
11 +   internal SQL tokeniser routines.
12 +
13 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
14 +   as a select statement, with or without CTEs.
15 +
16 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
17 +
18 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
19 +   internal SQL tokeniser routines.
20 +
21 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
22 +    being raised for valid set statements processed by a data formatter.
23 +
24 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
25 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
26 +   the path of the Firebird Library used by the database/services connection.
27 +
28 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
29 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
30 +   services connection.
31 +
32 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
33 +   or param name is not a valid SQL identifier.
34 +
35 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
36 +    view of whether the text box should be editable when no DataSource is specified.
37 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
38 +    ReadOnly is false, the text box is editable when no DataSource is specified.
39 +
40 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
41 +    the FBLIB environment variable. If you do not want to permit this then you
42 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
43 +    this setting.
44 +
45 + IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
46 +
47 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
48 +   Utf8EscapeControlChars
49 +
50 + IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
51 +
52 + IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
53 + all previous copies of the IBX source code tree before installing this release.
54 +
55 + The IBX packages used by most users have not changed, with one exception. The
56 + IBServices unit has been moved to the package iblegacyServices.lpk. To continue
57 + to use the IBServices unit in your applications, please add the iblegacyServices
58 + to the list of dependencies. To do this, open the Project Inspector and select
59 + Add->New Requirement and select "ibLegacyServices" from the list of available
60 + packages.
61 +
62 + 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
63 +   the IBServices unit providing what is intended to be a clearer and easier to
64 +   use set of IB Services components. See Chapter 10 of the IBX User Guide for
65 +   more information and the guide to "Firebird Service Management Using IBX".
66 +   As indicated above, the legacy services components are still available and
67 +   provided in a separate package. There is no need to update working applications
68 +   using the older versions except for an additional package dependency.
69 +
70 + 2. The IBX packages and source code tree have been re-organised in an attempt to
71 +   finally get rid of the "duplicate ppu" warnings. This re-organisation should
72 +   not affect existing users. Section 2.3 of the IBX User Guide describes the
73 +   new set of IBX packages.
74 +
75 + 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
76 +   updated to use the new Services API components.
77 +
78 + 4. The iblocal package has been updated to use the new Services API components.
79 +
80 + 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
81 +   TIBXSecurityService. It had been wrongly classified in the previous version
82 +   as a per database configuration item. It is global to a server and hence
83 +   correctly positioned as part of the Security Package. In the DBAdmin example,
84 +   the setting has moved to the mappings page.
85 +
86 + 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
87 +   are ignored.
88 +
89 + 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
90 +   closed before the database is dropped. Before and After Disconnect event handlers
91 +   are also fired.
92 +
93 + 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
94 +   is started and not just the first time.
95 +
96 + 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
97 +   depenendency with comp type.
98 +
99 + 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
100 +
101 + 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
102 +    then this is recognised and not ignored.
103 +
104 + 12. TIBDataSet, TIBQuery, TIBTable: additions:
105 +    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
106 +    function GetPerfStatistics(var stats: TPerfCounters): boolean;
107 +    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
108 +
109 +    GetRowsAffected returns the affected row counts from the last insert/update/delete
110 +    if EnableStatistics = true then GetPerfStatistics returns the current stats
111 +    counters for the select query. Note: stats accumulate after each fetch from
112 +    the database. To get total query cost after open, call the "Last" method
113 +    and then GetPerfStatistics.
114 +
115 +    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
116 +
117 + 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
118 +    in parenthesises.
119 +
120 + 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
121 +    SQL identifiers are always delimited by double quotes. If false, then they are
122 +    only delimited if the identifier is a reserved word, contains lower case or special
123 +    characters. Set this property to true to retain previous behaviour.
124 +
125 + 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
126 +    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
127 +
128 + 16. TIBDataSet, TIBQuery, TIBTable: addition:
129 +       property MasterDetailDelay: integer {defaults to zero}
130 +
131 +    When non-zero and the dataset is a detail table referencing a master table
132 +    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
133 +    then a synchronisation delay is added (in milliseconds) between the master
134 +    row changing and the detail dataset being re-opened. If the master dataset
135 +    is scrolled before the delay expires then the delay is reset. This can be used
136 +    to avoid performance overheads when scrolling through a large master dataset.
137 +
138 +    Note: uses fptimer and hence requires a thread manager. Under Linux the
139 +    chreads unit must be included in your project. TTimer is not used in order
140 +    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
141 +
142 + 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
143 +    with Extract Option eoDatabase.
144 +
145 + 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
146 +    When a deLayoutChanged event is reported on the ListSource dataset, the
147 +    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
148 +    relationship with the control's datasource (master).
149 +
150 + 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
151 +
152 + 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
153 +    stubs. Pedantic fix really, as procedures output in dependency order anyway.
154 +
155 + 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
156 +    DDL (Firebird 3 and later only).
157 +
158 + 22. TIBLookupComboBox Autocomplete Fixes:
159 +    i. Only appended text is now selected after autocomplete.
160 +    ii. Uppercase keys no longer ignored for autocomplete.
161 +    iii. Retain Prefix case is now honoured correctly.
162 +    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
163 +        before autocomplete performed. i.e. behaviour now the same as when
164 +        no DataSource assigned.
165 +
166 + 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
167 +    between SQL statements.
168 +
169 + 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
170 +    ObjectNames are converted to upper case before matching against metadata object
171 +    names, unless the objectname is delimited by double quotes, in which case, the
172 +    double quotes are removed and the remaining string is used (unmodified) to match
173 +    against the metadata object name.
174 +
175 +    If true then the ObjectName is used as is without modification and matched
176 +    against the metadata object name. No attempt is made to remove double quotes.
177 +
178 + 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
179 +    with eoTrigger, these extract types can be used to select only Database Triggers,
180 +    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
181 +
182 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
183 +    statement separate character is now reset to the default (';').
184 +
185 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
186 +
187 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
188 +    a commit or reconnect statement and instead activated only when next SQL statement
189 +    is executed.
190 +
191 + 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
192 +
193 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
194 +    converting statement to upper case.
195 +
196 + 31. TIBExtract: metadata comments now supported. New published property
197 +    IncludeMetaDataComments (default true). If true then metadata comments included
198 +    in extracted DDL. New Extract Object member eoComments. This may be used with
199 +    ExtractObject method to list all metadata comments.
200 +
201 + 32. TIBExtract: ListObjectNames method added.
202 +
203 + 33. Updated Database component editor to support additional connection string
204 +    types.
205 +
206 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
207 +
208 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
209 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
210 + RELEASE.
211 +
212 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
213 +
214 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
215 +
216 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
217 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
218 +   information). However, this is also a very useful mechanism for returning updated computed by
219 +   column values. Values returned as a result of executing an Insert or Update statement
220 +   replace existing values in the current row for each corresponding column.
221 +
222 +   Previously, if a dataset's select query included read only (computed by) fields then
223 +   an automatic row refresh was performed after an insert or update query had been processed,
224 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
225 +   that an automatic refresh is no longer performed if an insert or update query contains
226 +   a returning clause that updates one or more fields on the current row. A full row
227 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
228 +   field values and the select query contains read only fields. Use of Insert/update
229 +   returning should be significantly more efficient than executing a refresh query.
230 +
231 +   This behaviour change is intended to be backwards compatible and there should be no need to change
232 +   existing programs, other than to improve performance by using the new capability.
233 +
234 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
235 +   they are called when the dataset row is being deleted, there is no value in
236 +   updating the current record from the query result. Instead, a new event handler
237 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
238 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
239 +   by the query. The event handler can then interrogate the query results and
240 +   perform whatever action is necessary. For example to confirm, to the user,
241 +   the deletion of a row with the returned values.
242 +
243 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
244 +   any Computed By or Identity Columns. The IBTables example has been updated to
245 +   illustrate the computation of the employee Full Name on update.
246 +
247 + 5. TIBTable: The GeneratorField property is now published.
248 +
249 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
250 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
251 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
252 +   each Identity column after the insert is executed.
253 +
254 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
255 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
256 +   Insert..Returning clause.
257 +
258 + 8. TIBGenerator: small performance improvement by not preparing query each time
259 +   a new value is generated.
260 +
261 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
262 +
263 + 10. Property editors will now sync table name to a System Table when "Include System
264 +    Tables" is selected and the query is for a System Table.
265 +
266 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
267 +    values are no longer converted to milliseconds from TDateTime and then back again
268 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
269 +
270 + 12. Property Editors handling of Stored Procedures.
271 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
272 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
273 +      query).
274 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
275 +
276 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
277 +    can be used to select a package. If non-empty, the stored procedure name is
278 +    expected to be a stored procedure defined in the specified package and the
279 +    generated SQL will be as required for a stored procedure located in a package.
280 +
281 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
282 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
283 +    which a stored procedure can be selected. With no package name selected, non-package
284 +    stored procedures are listed.
285 +
286 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
287 +    for password on reconnect.
288 +
289 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
290 +    and character set name.
291 +
292 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
293 +    DB info lookups"
294 +
295 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
296 +
297 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
298 +
299 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
300 +    parameters. This stops an exception being raised when the field cannot be
301 +    located in the record buffer.
302 +
303 + 21. Property Editors now automatically include System Tables when opened and when the query table
304 +    is a System Table.
305 +
306 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
307 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
308 +
309 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
310 +    add the SPB item isc_spb_expected_db. This names a database using
311 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
312 +    database. examples/services re-written to illustrate use of "expected_db".
313 +
314 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
315 +    This avoids truncated backups when the server returns a timeout (busy) response.
316 +
317 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
318 +
319 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
320 +    databasenames. These are respectively expanded to the local system's temp directory
321 +    (including trailing delimiter) or to a prescribed data directory (including
322 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
323 +    in the user's home directory. The hidden directory name is either the string returned
324 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
325 +    Under Windows, the directory is the same as the Data Directory as decribed
326 +    above but instead prefixed by the User's application data path. These may be
327 +    used to improve application portability for Personal Databases.
328 +
329 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
330 +    this has not worked for a long time and is not useful either. FieldDefs should be
331 +    managed using the Fields Editor as with any other dataset. To access the fields
332 +    editor for a TIBTable component, double click on the component. The fields editor
333 +    is then displayed.
334 +
335 + 28. TIBDatabaseInfo: new properties/function
336 +     * DateDBCreated (returns date/time database created)
337 +     * TransactionCount (returns no. of active transactions)
338 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
339 +     * PagesFree (Firebird 3 or later)
340 +     * PagesUsed (Firebird 3 or later)
341 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
342 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
343 +
344 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
345 +
346 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
347 +
348 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
349 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
350 +
351 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
352 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
353 +    firing during backup and restore.
354 +
355 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
356 +    for verbose output using the new property "StatisticsRequested".
357 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
358 +
359 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
360 +
361 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
362 +    palette. This uses the online validation feature added in Firebird 2.5. The
363 +    services's properties enable inclusion/exclusion of tables and indexes using
364 +    regular expressions. See.
365 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
366 +
367 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
368 +    option on a database.
369 +
370 + 37. TIBCustomService: Assign method implemented to allow copying of service login
371 +    context between service API components. "Detach" method now only detaches
372 +    service when last reference to the service interface detaches. Tidy up of
373 +    code for SetActive and Attach methods including password hiding.
374 +
375 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
376 +    and used to determine the auth method and protocol used for the connection.
377 +
378 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
379 +    a Create Database Statement generated by IBX.
380 +
381 + 40. All IBServices now have an additional published property "PortNo". This may
382 +    be set to a non-standard port number when necessary. If zero then the default
383 +    port number is used.
384 +
385 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
386 +    and not just the mouse.
387 +
388 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
389 +
390 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
391 +    image index and selected image index for each node to be set from a database field.
392 +
393 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
394 +    then database schema includes grants to all users. If not present then the
395 +    only user grants included are those to User PUBLIC.
396 +
397 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
398 +    and child nodes in dataset.
399 +
400 +
401 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
402 +
403 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
404 +   changes.
405 +
406 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
407 +   Bug could result in truncated multi-byte character set values.
408 +
409 + 3. Changes consequential on moving fbintf character set utility functions from
410 +   IFirebirdAPI to IAttachment.
411 +
412 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
413 +
414 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
415 +   results in autocomplete ignoring prefix text.
416 +
417 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
418 +   entering a new name into the text box.
419 +
420 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
421 +   Firebird rather than recomputing it.
422 +
423 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
424 +   screen centre. Previously some were "poDesigned" which may be inappropriate
425 +   for multi monitor desktops.
426 +
427 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
428 +
429 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
430 +    a transaction and always reset the object.
431 +
432 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
433 +
434 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
435 +
436 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
437 +    to a gbak format archive.
438 +
439 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
440 +
441 + 16. IBLocaldb: Drop database if error creating an empty database.
442 +
443 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
444 +    unless selected node not in current dataset.
445 +
446 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
447 +    to TIBCustomService, and IBlocalDB code tidy up.
448 +
449 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
450 +    behaviour due to uninitialised variable.
451 +
452 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
453 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
454 +
455 + 21. IBSQL: When Database changed ensure that all resources are freed.
456 +
457 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
458 +
459 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
460 +    * Line Wrap on SQL Token boundaries (on user command)
461 +    * auto-complete table names in drop down list of table names
462 +    * Double click on tablename or field name adds to SQL text
463 +
464 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
465 +
466 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
467 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
468 +    workaround for a problem in fpc 3.0.4 win64).
469 +
470 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
471 +
472 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
473 +
474 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
475 +
476 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
477 +   include remote system name.
478 +
479 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
480 +   tables when data included in output.
481 +
482 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
483 +   and timing information to be written to stdout. This may be used to locate
484 +   performance bottlenecks.
485 +
486 + 4. SQLParser: only call "OnChanging" event handler when value is different.
487 +
488 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
489 +
490 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
491 +   that BindFields is called when the query is next activated. Avoids FieldName
492 +   not found error.
493 +
494 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
495 +   purpose and allows the programmer to define any action they want for Update, Insert
496 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
497 +   filtering of updates, or use of statements such as Grant or Revoke instead of
498 +   normal DML. See User Manual for more information.
499 +
500 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
501 +
502 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
503 +
504 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
505 +
506 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
507 +   hexadecimal notation.
508 +
509 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
510 +   using a simple XML format.
511 +
512 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
513 +   grants to these objects.
514 +
515 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
516 +   dependency problems restoring complex databases.
517 +
518 + 7. TIBXScript: This component has been restructured to allow for the processing of
519 +   embedded XML in INSERT statements and to support interactive sources in addition
520 +   to non-interactive data sources such as files.
521 +
522 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
523 +
524 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
525 +   SET SQL DIALECT
526 +   SET TERM
527 +   SET AUTODDL
528 +   SET BAIL
529 +   SET ECHO
530 +   SET COUNT
531 +   SET STATS
532 +   SET NAMES <character set>
533 +
534 + 10. IBVersion unit added to hold current IBX Version Number information.
535 +
536 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
537 +    and domain definitions.
538 +
539 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
540 +    fully supported.
541 +
542 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
543 +
544 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
545 +
546 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
547 +
548 + See also doc/IBX4LazarusGuide.pdf for important information on
549 + upgrading to IBX2.
550 +
551 + 1. Size property of TIBStringField is now the width in characters of the field
552 +   and not the byte length. This applies only to multi-byte character sets such
553 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
554 +   code is not recognised as a bug and hence this change to align the behaviour.
555 +   The TStringField change is expected in fpc 3.2.0.
556 +
557 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
558 +   true (default) then Size property value saved in the lfm is ignored. Size is
559 +   always set from the dynamic information read from the database. It is unclear
560 +   why anyone would want to override this and set Size to false.
561 +
562 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
563 +   block.
564 +
565 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
566 +   exist when an attempt is made to connect to it (run time only) then an attempt
567 +   is made to create the database.
568 +
569 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
570 +   has been successfully created as a result of a call to CreateDatabase or when
571 +   creating a database after it was found not to exist.
572 +
573 + 6.  DBControlGrid: a race condition could result in the wrong row image being
574 +    written to the cache. This has been avoided by a trip round the message
575 +    loop before rendering the row image.
576 +
577 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
578 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
579 +    known to risk corrupt rendering of row images when the control is first
580 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
581 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
582 +
583 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
584 +    a TDateEdit control located on an editor panel.
585 +
586 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
587 +
588 + 10. DBControlGrid: Removed memory leak when updating rows.
589 +
590 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
591 +
592 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
593 +
594 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
595 +   when target codepage is CP_NONE. This is a workaround for
596 +   http://bugs.freepascal.org/view.php?id=30622.
597 +
598 + 2. DBLog option removed from TIBStatisticalService - not supported by server
599 +   since Firebird 1.5.
600 +
601 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
602 +   similar.
603 +
604 + 4. IBCodePage: updated mapping between codepages and character id.
605 +
606 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
607 +   Firebird. Character sets with a char width of two are not UTF16.
608 +
609 + 6. Strings received from the database are now always transliterated into UTF8
610 +   regardless of the database character set or connection character set. This
611 +   is for compatibility with the LCL.
612 +
613 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
614 +
615 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
616 +   read in an entire blob just to get the size of the blob. General performance
617 +   improvement when opening datasets containing blobs.
618 +
619 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
620 +
621 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
622 +   is now used.
623 +
624 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
625 +   determined.
626 +
627 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
628 +
629 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
630 +   lazarus 1.6.0
631 +
632 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
633 +   compilation error.
634 +
635 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
636 +
637 + 1. No character set specified for connection: when a text blob is retrieved, the
638 +  character set is determined by looking up the native character set using then
639 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
640 +  set as the connection.
641 +
642 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
643 +   for Login Dialog returing a change to the database path.
644 +
645 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
646 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
647 +   entered value to be saved on a project specific basis (design time only).
648 +
649 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
650 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
651 +   Otherwise, it sets the column text to the selected ListField Value.
652 +
653 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
654 +   column width.
655 +
656 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
657 +   and a case insensitive search is requested.
658 +
659 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
660 +   or column ListSource.
661 +
662 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
663 +   unprepare) when closing and the text has not changed.
664 +
665 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
666 +   Less likely to cause a cursor re-use error on Windows.
667 +
668 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
669 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
670 +
671 + 11. TIBTreeView: Guard against nil destination on record changed
672 +
673 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
674 +    string type with the code page set to reflect the returned field encoding after
675 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
676 +    earlier versions.
677 +
678 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
679 +    will now result in transliteration to the code page specified for the Firebird driver
680 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
681 +
682 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
683 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
684 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
685 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
686 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
687 +    the GETACP is used to determine the Windows code page.
688 +
689 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
690 +    name used as the lc_ctype when the database was opened. Only valid while the
691 +    Database is connected.
692 +
693 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
694 +    id that corresponds to the DefaultCharSetName.
