1 tony 319 IBX Change Log version (2.4-0 Build 12517) Fri, 19 Feb 2021 13:27:20 +0000
2 tony 315
3     1. Firebird 4 support added.
4    
5     2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
6     extended precision NUMERIC fields are supported.
7    
8     3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
9    
10     4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
11     and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
12    
13     5. IBExtract now supports FB4 enhancements:
14     - new data types as above
15     - Identity column extensions
16     - Default user role
17     - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
18     - Internal Functions
19    
20     6. IBExtract: new event: OnExtractLines.
21    
22     7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
23    
24     8. IBXServices: Server version no. parsing now allows any letter before major version number
25     and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
26    
27     9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
28     format for rendering a time zone.
29    
30     10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
31     to convert TIME WITH TIME ZONE data type values to and from GMT.
32    
33     11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
34     IIBGUIInterface and IIBTimerInf respectively.
35    
36     12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
37     now accessible as properties of TIBDatabase and TIBTransaction respectively.
38    
39     13. String Fields: when a fixed character with (CHAR) field is returned, it is now
40     truncated to its fixed character width rather than being right padded with
41     white space to the maximum data size.
42    
43     14. TIBTable.Empty table. In additional to deleting all records in the underlying
44     table, the internal buffers are now also flushed ensuring that the TIBTable is
45     also empty.
46    
47     15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
48    
49     16. TIBXControlService descendents: DatabaseName may now be set using a database
50     connect string. The database name is extracted from the connect string.
51    
52     17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
53    
54     18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
55    
56     19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
57     not being present as required.
58    
59     20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
60     version that can be customised to work with other database drivers.
61    
62 tony 319 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
63     unnecessary CR at end of line on Unix platforms.
64    
65     22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
66     seconds in order to reduce risk of message loss.
67    
68     23. ISQLMonitor: read and write count statistics now available via:
69     property TIBSQLMonitor.ReadCount;
70     IIBSQLMonitorHook.GetWriteCount: integer;
71    
72     24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
73    
74 tony 312 IBX Change Log version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
75 tony 308
76     1. TIBStringField: when a string value is read from a dataset buffer, if the
77     number of UTF8 characters exceeds the string size then string is truncated
78     to the maximum string size. This is usually a problem with fixed width columns
79     right padded with white space.
80    
81     2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
82     If SQLFiltered is set then when a dataset is opened, each line in the
83     SQLFilterParams property is assumed to be a SQL condition clause and
84     ANDed into the Where clause of the SQL Select statement provided as a
85     dataset property. Each such SQL condition thus acts as an additional filter
86 tony 315 on the dataset.
87 tony 308
88     3. The Filtered property inherited from TDataset is no longer used for SQL (server
89     side filters).
90    
91 tony 311 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
92     text matches complete entry.
93    
94     5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
95     dataset are active (avoids risk of access violation if master is inactive)
96    
97     6. TIBEvents: Registered property can now be set at design time even if database not open
98    
99     7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
100     This should prevent "spillover" of events between sessions.
101    
102     8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
103     This should ensure that the internal buffer is set up correctly and avoids
104     a duplicate initial row.
105    
106     9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
107     That is, the DataSize should be the field size * character set width. The
108     value returned by DataSize is now the same as the Dataset buffer size reserved
109     for the field.
110    
111 tony 312 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
112 tony 311
113     11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
114     and vice-versa. This may result in an exception being raised (correctly) for
115     older programs when using dataset fields added to a form and the database has been
116     upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
117     In such cases, the field needs to be deleted in the IDE fields editor and then
118     added back in.
119    
120 tony 312 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
121 tony 315 false if query contains only white space and not just empty.
122 tony 312
123 tony 311 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
124     should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
125     is cancelled.
126    
127 tony 315 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
128     called on a null field.
129    
130     14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
131     results in an empty dataTC86 Client side Filtered Dataset 1 X
132     set.
133    
134     15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
135     a cached update is applied and an exception is raised.
136    
137     16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
138    
139     17. Console Mode Local Database support: backup/restore should now work correctly.
140    
141     18. Local Database Support: if an upgrade fails, a downgrade is now performed if
142     possible and an exception raised.
143    
144     19. MinimumVersionNo added to Local Database Support. Database will not open if
145     below this version no. and upgrade not possible.
146    
147 tony 307 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
148 tony 306
149 tony 307 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
150     not SQL Identifiers are now supported.
151 tony 306
152 tony 307 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
153     passed to the Firebird engine for execution.
154 tony 306
155 tony 307 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
156     is made to scroll back.
157 tony 306
158 tony 307 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
159 tony 306
160 tony 307 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
161     only enclosed in double quotes in SQL dialect 3 and when it needs to be.
162 tony 306
163 tony 307 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
164     validated. If no match is found in the list of field names and the database has
165     been opened in SQL Dialect 3, then the ListField Name is converted to upper case
166     if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
167 tony 306
168 tony 307 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
169     with fpc 3.2.
170 tony 306
171 tony 307 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
172 tony 287
173    
174 tony 307 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
175     and is used to override the default settings in the client side "firebird.conf" This
176     includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
177     Each line of the string list should be a setting in the same format as "firebird.conf".
178     For example "WireCompression = true" in order to request wire compression on the client side.
179 tony 287
180 tony 307 Note: explicit settings in the client side "firebird.conf" appear to take precedence
181     over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
182     also require a compatible setting in the server side "firebird.conf". For example
183     "WireCompression = true" must also be set in the server's "firebird.conf" for wire
184     compression to be used.
185 tony 291
186 tony 307 Whether or not WireCompression or WireCrypt are in use can be checked using the information
187     returned with the Client/Server protocol version. See ibx/examples/dbadmin and
188     ibx/examples/dbinfo for examples of how to display this information.
189 tony 291
190 tony 307 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
191     is a "convenience" property. If set the "WireCompression=true" is added to the
192     ConfigOverrides. If unchecked then this setting is removed.
193 tony 291
194 tony 307 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
195     not "INT64".
196 tony 291
197 tony 307 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
198     These are:
199     property TimestampFormat: string;
200     property DateFormat: string;
201     property TimeFormat: string;
202 tony 291
203 tony 307 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
204     DATETIME and TIME. The format strings use the standard FPC date/time format
205     characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
206 tony 266
207 tony 307 If any of the above properties are set to an empty string, then the locale default
208     is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
209     locale default is extended by appending '.zzz' to include milliseconds.
210 tony 272
211 tony 307 TIBCSVDataOut by default sets these properties to the empty string, while the other
212     two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
213 tony 266
214 tony 307 5. New published property for TIBCSVDataOut:
215     property QuoteStrings: boolean (default true)
216 tony 266
217 tony 307 If false then strings are unquoted, otherwise, the QuoteChar property value is
218     used to delimit each and every string in the output.
219 tony 263
220 tony 307 6. New published properties for TIBCSVDataOut:
221     property FieldSeparator: string;
222     property HeaderSeparator: string;
223 tony 267
224 tony 307 Respectively, these provide the separator character(s) used to separate fields
225     in data and header rows. Both default to ','.
226 tony 270
227 tony 307 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
228     TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
229     property OnFormatTextString;
230 tony 270
231 tony 307 This event handler can be used to process text strings before they are included
232     in the output e.g. to replace unprintable characters with alternative strings.
233     This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
234 tony 270
235 tony 307 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
236     Uses "FindParam" if in order to find out if a parameter with a given name exists
237     and without raising and exception if it does not.
238 tony 270
239 tony 307 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
240     consistency with SQL queries.
241 tony 270
242 tony 307 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
243     When true, SQL statement parameter names are parsed case sensitive. Note for
244     TIBDataSet only applies to Select query.
245 tony 270
246 tony 307 11. IBEvents: removing a TIBEvent component from a form should no longer result in
247     an IDE exception.
248 tony 270
249 tony 307 12. LocalDBSupport: initial database creation should now work correctly
250     when the schema source is an sql file.
251 tony 270
252 tony 307 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
253     when defined, this handler will be called by the internal TIBXScript during
254     initial database creation when the schema source is an sql file and may be used
255     to provide a visual indication of progress in console mode.
256 tony 270
257 tony 307 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
258     to true while a new local database is being created and its schema populated.
259     Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
260     when the database is disconnected/connected during the create DB procedure.
261 tony 270
262 tony 307 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
263     are now always ignored and replaced by the user name and password provided as
264     the login parameters for the TIBDatabase referenced from the TIBXScript. The
265     IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
266     completely ignored if this property is true.
267 tony 270
268 tony 307 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
269     to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
270     ImageIndex and SelectImageIndex values on AddNode.
271 tony 270
272 tony 307 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
273     read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
274     the same database connection.
275 tony 270
276 tony 307 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
277     if provided, this should be an conditional SQL expression suitable for
278     including in an SQL Select statement "where" clause. If non-empty and the
279     "Filtered" property is true then the SQL expression provided as the value of
280     the "Filter" property is "ANDed" with any existing condition statement
281     in the SQL statement's "Where" clause.
282 tony 270
283 tony 307 If the "Filter" property is set at run time, the "Filtered" property is true
284     and the dataset is already open, then the dataset is closed and re-opened automatically.
285 tony 271
286 tony 307 The "Filter" condition may include IBX style parameters. In which case, their
287     value must be set by the dataset's "OnBeforeOpen" event handler.
288 tony 272
289 tony 307 This is a public property for TIBDataSet and TIBQuery query and intended for
290     use at run time.
291 tony 272
292 tony 307 Note: The property is a published property of TIBTable. The TIBTable functionality
293     is unaffected by this change.
294 tony 272
295 tony 307 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
296 tony 272
297 tony 307 1. Remove need to check for IsMultiThread by providing access to GUI timers via
298     IBGUIInterface. Note: master/detail delay timer does not apply to console
299     mode apps.
300 tony 272
301 tony 307 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
302     statement. This avoids problems if "Execute Block" is used as the Query.
303 tony 272
304 tony 307 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
305     internal SQL tokeniser routines.
306 tony 272
307 tony 307 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
308     as a select statement, with or without CTEs.
309 tony 272
310 tony 307 5. IBSQLParser: parser now recognises the "ROWS" clause.
311 tony 272
312 tony 307 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
313     internal SQL tokeniser routines.
314 tony 272
315 tony 307 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
316     being raised for valid set statements processed by a data formatter.
317 tony 272
318 tony 307 8. New published property for TIBDatabase and TIBXServicesConnection. This is
319     FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
320     the path of the Firebird Library used by the database/services connection.
321 tony 267
322 tony 307 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
323     is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
324     services connection.
325 tony 263
326 tony 307 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
327     or param name is not a valid SQL identifier.
328 tony 263
329 tony 307 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
330     view of whether the text box should be editable when no DataSource is specified.
331     TIBLookupComboEditBox has been updated to workaround this problem. As long as
332     ReadOnly is false, the text box is editable when no DataSource is specified.
333 tony 263
334 tony 307 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
335     the FBLIB environment variable. If you do not want to permit this then you
336     must modify the Register procedure in the design/IBDBReg.pas unit to remove
337     this setting.
338 tony 263
339 tony 307 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
340 tony 263
341 tony 307 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
342     Utf8EscapeControlChars
343 tony 263
344 tony 307 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
345 tony 263
346 tony 307 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
347     all previous copies of the IBX source code tree before installing this release.
348 tony 263
349 tony 307 The IBX packages used by most users have not changed, with one exception. The
350     IBServices unit has been moved to the package iblegacyServices.lpk. To continue
351     to use the IBServices unit in your applications, please add the iblegacyServices
352     to the list of dependencies. To do this, open the Project Inspector and select
353     Add->New Requirement and select "ibLegacyServices" from the list of available
354     packages.
355 tony 263
356 tony 307 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
357     the IBServices unit providing what is intended to be a clearer and easier to
358     use set of IB Services components. See Chapter 10 of the IBX User Guide for
359     more information and the guide to "Firebird Service Management Using IBX".
360     As indicated above, the legacy services components are still available and
361     provided in a separate package. There is no need to update working applications
362     using the older versions except for an additional package dependency.
363 tony 263
364 tony 307 2. The IBX packages and source code tree have been re-organised in an attempt to
365     finally get rid of the "duplicate ppu" warnings. This re-organisation should
366     not affect existing users. Section 2.3 of the IBX User Guide describes the
367     new set of IBX packages.
368 tony 263
369 tony 307 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
370     updated to use the new Services API components.
371 tony 263
372 tony 307 4. The iblocal package has been updated to use the new Services API components.
373 tony 241
374 tony 307 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
375     TIBXSecurityService. It had been wrongly classified in the previous version
376     as a per database configuration item. It is global to a server and hence
377     correctly positioned as part of the Security Package. In the DBAdmin example,
378     the setting has moved to the mappings page.
379 tony 241
380 tony 307 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
381     are ignored.
382 tony 101
383 tony 307 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
384     closed before the database is dropped. Before and After Disconnect event handlers
385     are also fired.
386 tony 209
387 tony 307 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
388     is started and not just the first time.
389 tony 209
390 tony 307 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
391     depenendency with comp type.
392 tony 209
393 tony 307 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
394 tony 209
395 tony 307 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
396     then this is recognised and not ignored.
397 tony 209
398 tony 307 12. TIBDataSet, TIBQuery, TIBTable: additions:
399     function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
400     function GetPerfStatistics(var stats: TPerfCounters): boolean;
401     property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
402 tony 209
403 tony 307 GetRowsAffected returns the affected row counts from the last insert/update/delete
404     if EnableStatistics = true then GetPerfStatistics returns the current stats
405     counters for the select query. Note: stats accumulate after each fetch from
406     the database. To get total query cost after open, call the "Last" method
407     and then GetPerfStatistics.
408 tony 209
409 tony 307 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
410 tony 209
411 tony 307 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
412     in parenthesises.
413 tony 209
414 tony 307 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
415     SQL identifiers are always delimited by double quotes. If false, then they are
416     only delimited if the identifier is a reserved word, contains lower case or special
417     characters. Set this property to true to retain previous behaviour.
418 tony 209
419 tony 307 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
420     are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
421 tony 209
422 tony 307 16. TIBDataSet, TIBQuery, TIBTable: addition:
423     property MasterDetailDelay: integer {defaults to zero}
424 tony 209
425 tony 307 When non-zero and the dataset is a detail table referencing a master table
426     through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
427     then a synchronisation delay is added (in milliseconds) between the master
428     row changing and the detail dataset being re-opened. If the master dataset
429     is scrolled before the delay expires then the delay is reset. This can be used
430     to avoid performance overheads when scrolling through a large master dataset.
431 tony 209
432 tony 307 Note: uses fptimer and hence requires a thread manager. Under Linux the
433     chreads unit must be included in your project. TTimer is not used in order
434     to avoid an LCL dependency. Requires FPC 3.0.2 or later.
435 tony 209
436 tony 307 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
437     with Extract Option eoDatabase.
438 tony 209
439 tony 307 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
440     When a deLayoutChanged event is reported on the ListSource dataset, the
441     combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
442     relationship with the control's datasource (master).
443 tony 209
444 tony 307 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
445 tony 209
446 tony 307 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
447     stubs. Pedantic fix really, as procedures output in dependency order anyway.
448 tony 209
449 tony 307 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
450     DDL (Firebird 3 and later only).
451 tony 209
452 tony 307 22. TIBLookupComboBox Autocomplete Fixes:
453     i. Only appended text is now selected after autocomplete.
454     ii. Uppercase keys no longer ignored for autocomplete.
455     iii. Retain Prefix case is now honoured correctly.
456     iv. When a DataSource is assigned, typing after autocomplete now extends prefix
457     before autocomplete performed. i.e. behaviour now the same as when
458     no DataSource assigned.
459 tony 209
460 tony 307 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
461     between SQL statements.
462 tony 209
463 tony 307 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
464     ObjectNames are converted to upper case before matching against metadata object
465     names, unless the objectname is delimited by double quotes, in which case, the
466     double quotes are removed and the remaining string is used (unmodified) to match
467     against the metadata object name.
468 tony 209
469 tony 307 If true then the ObjectName is used as is without modification and matched
470     against the metadata object name. No attempt is made to remove double quotes.
471 tony 209
472 tony 307 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
473     with eoTrigger, these extract types can be used to select only Database Triggers,
474     or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
475 tony 209
476 tony 307 26. TIBXScript: If an exception occurs during the processing of a statement, the
477     statement separate character is now reset to the default (';').
478 tony 221
479 tony 307 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
480 tony 221
481 tony 307 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
482     a commit or reconnect statement and instead activated only when next SQL statement
483     is executed.
484 tony 221
485 tony 307 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
486 tony 225
487 tony 307 30. TIBXScript: case insensitive regex now used when matching statements instead of
488     converting statement to upper case.
489 tony 225
490 tony 307 31. TIBExtract: metadata comments now supported. New published property
491     IncludeMetaDataComments (default true). If true then metadata comments included
492     in extracted DDL. New Extract Object member eoComments. This may be used with
493     ExtractObject method to list all metadata comments.
494 tony 225
495 tony 307 32. TIBExtract: ListObjectNames method added.
496 tony 225
497 tony 307 33. Updated Database component editor to support additional connection string
498     types.
499 tony 226
500 tony 307 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
501 tony 227
502 tony 307 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
503     AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
504     RELEASE.
505 tony 229
506 tony 307 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
507 tony 229
508 tony 307 1. IBExtract: Identity columns - add additional check for null column for generator name.
509 tony 229
510 tony 307 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
511     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
512     information). However, this is also a very useful mechanism for returning updated computed by
513     column values. Values returned as a result of executing an Insert or Update statement
514     replace existing values in the current row for each corresponding column.
515 tony 229
516 tony 307 Previously, if a dataset's select query included read only (computed by) fields then
517     an automatic row refresh was performed after an insert or update query had been processed,
518     irrespective of the setting of the "ForcedUpdates" property. This has changed such
519     that an automatic refresh is no longer performed if an insert or update query contains
520     a returning clause that updates one or more fields on the current row. A full row
521     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
522     field values and the select query contains read only fields. Use of Insert/update
523     returning should be significantly more efficient than executing a refresh query.
524 tony 229
525 tony 307 This behaviour change is intended to be backwards compatible and there should be no need to change
526     existing programs, other than to improve performance by using the new capability.
527 tony 229
528 tony 307 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
529     they are called when the dataset row is being deleted, there is no value in
530     updating the current record from the query result. Instead, a new event handler
531     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
532     an OnDeleteReturning event handler is provided then it is called with the IResults returned
533     by the query. The event handler can then interrogate the query results and
534     perform whatever action is necessary. For example to confirm, to the user,
535     the deletion of a row with the returned values.
536 tony 231
537 tony 307 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
538     any Computed By or Identity Columns. The IBTables example has been updated to
539     illustrate the computation of the employee Full Name on update.
540 tony 209
541 tony 307 5. TIBTable: The GeneratorField property is now published.
542 tony 151
543 tony 307 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
544     When InsertSQL is generated, the Identity columns are not included in the list of values to
545     be inserted. A RETURNING clause is added to the insert statement to return the value of
546     each Identity column after the insert is executed.
547 tony 151
548 tony 307 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
549     Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
550     Insert..Returning clause.
551 tony 101
552 tony 307 8. TIBGenerator: small performance improvement by not preparing query each time
553     a new value is generated.
554 tony 101
555 tony 307 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
556    
557     10. Property editors will now sync table name to a System Table when "Include System
558     Tables" is selected and the query is for a System Table.
559    
560     11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
561     values are no longer converted to milliseconds from TDateTime and then back again
562     to TDateTime (the conversion to milliseconds is the default TDataset approach).
563    
564     12. Property Editors handling of Stored Procedures.
565     * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
566     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
567     query).
568     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
569    
570     13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
571     can be used to select a package. If non-empty, the stored procedure name is
572     expected to be a stored procedure defined in the specified package and the
573     generated SQL will be as required for a stored procedure located in a package.
574    
575     14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
576     a "Package Name" drop down box to allow selection of a Firebird 3 Package from
577     which a stored procedure can be selected. With no package name selected, non-package
578     stored procedures are listed.
579    
580     15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
581     for password on reconnect.
582    
583     16. TIBDatabase: use IAttachment for connection default character set id, code page
584     and character set name.
585    
586     17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
587     DB info lookups"
588    
589     18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
590    
591     19. Add a property Editor for TIBUpdate.RefreshSQL.
592    
593     20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
594     parameters. This stops an exception being raised when the field cannot be
595     located in the record buffer.
596    
597     21. Property Editors now automatically include System Tables when opened and when the query table
598     is a System Table.
599    
600     22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
601     This avoids errors due to a stale SQRB or SRB being used for the next query.
602    
603     23. IBServices: Service attach parameters now include "expected_db". This is used to
604     add the SPB item isc_spb_expected_db. This names a database using
605     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
606     database. examples/services re-written to illustrate use of "expected_db".
607    
608     24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
609     This avoids truncated backups when the server returns a timeout (busy) response.
610    
611     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
612    
613     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
614     databasenames. These are respectively expanded to the local system's temp directory
615     (including trailing delimiter) or to a prescribed data directory (including
616     trailing delimiter). Under Unix systems the data directory is a hidden directory
617     in the user's home directory. The hidden directory name is either the string returned
618     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
619     Under Windows, the directory is the same as the Data Directory as decribed
620     above but instead prefixed by the User's application data path. These may be
621     used to improve application portability for Personal Databases.
622    
623     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
624     this has not worked for a long time and is not useful either. FieldDefs should be
625     managed using the Fields Editor as with any other dataset. To access the fields
626     editor for a TIBTable component, double click on the component. The fields editor
627     is then displayed.
628    
629     28. TIBDatabaseInfo: new properties/function
630     * DateDBCreated (returns date/time database created)
631     * TransactionCount (returns no. of active transactions)
632     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
633     * PagesFree (Firebird 3 or later)
634     * PagesUsed (Firebird 3 or later)
635     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
636     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
637    
638     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
639    
640     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
641    
642     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
643     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
644    
645     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
646     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
647     firing during backup and restore.
648    
649     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
650     for verbose output using the new property "StatisticsRequested".
651     see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
652    
653     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
654    
655     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
656     palette. This uses the online validation feature added in Firebird 2.5. The
657     services's properties enable inclusion/exclusion of tables and indexes using
658     regular expressions. See.
659     https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
660    
661     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
662     option on a database.
663    
664     37. TIBCustomService: Assign method implemented to allow copying of service login
665     context between service API components. "Detach" method now only detaches
666     service when last reference to the service interface detaches. Tidy up of
667     code for SetActive and Attach methods including password hiding.
668    
669     38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
670     and used to determine the auth method and protocol used for the connection.
671    
672     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
673     a Create Database Statement generated by IBX.
674    
675     40. All IBServices now have an additional published property "PortNo". This may
676     be set to a non-standard port number when necessary. If zero then the default
677     port number is used.
678    
679     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
680     and not just the mouse.
681    
682     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
683    
684     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
685     image index and selected image index for each node to be set from a database field.
686    
687     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
688     then database schema includes grants to all users. If not present then the
689     only user grants included are those to User PUBLIC.
690    
691     45. TIBTreeView: performance improvement. When expanding include both expanded node
692     and child nodes in dataset.
693    
694    
695     IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
696    
697     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
698     changes.
699    
700     2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
701     Bug could result in truncated multi-byte character set values.
702    
703     3. Changes consequential on moving fbintf character set utility functions from
704     IFirebirdAPI to IAttachment.
705    
706     4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
707    
708     5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
709     results in autocomplete ignoring prefix text.
710    
711     6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
712     entering a new name into the text box.
713    
714     7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
715     Firebird rather than recomputing it.
716    
717     8. Property Editor positioning tidy up: All IBX Property editors should now be
718     screen centre. Previously some were "poDesigned" which may be inappropriate
719     for multi monitor desktops.
720    
721     10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
722    
723     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
724     a transaction and always reset the object.
725    
726     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
727    
728     13. TIBXScript: Allow for override of database filename in Create Database statements.
729    
730     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
731     to a gbak format archive.
732    
733     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
734    
735     16. IBLocaldb: Drop database if error creating an empty database.
736    
737     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
738     unless selected node not in current dataset.
739    
740     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
741     to TIBCustomService, and IBlocalDB code tidy up.
742    
743     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
744     behaviour due to uninitialised variable.
745    
746     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
747     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
748    
749     21. IBSQL: When Database changed ensure that all resources are freed.
750    
751     22. IBCustomDataset: When database changed ensure that queries an unprepared.
752    
753     23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
754     * Line Wrap on SQL Token boundaries (on user command)
755     * auto-complete table names in drop down list of table names
756     * Double click on tablename or field name adds to SQL text
757    
758     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
759    
760     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
761     TVariantArray. Seems to avoid memory corruption in Windows (probably a
762     workaround for a problem in fpc 3.0.4 win64).
763    
764     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
765    
766     27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
767    
768     IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
769    
770     1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
771     include remote system name.
772    
773     2. TIBExtract: No longer include comment header and COMMIT statement for empty
774     tables when data included in output.
775    
776     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
777     and timing information to be written to stdout. This may be used to locate
778     performance bottlenecks.
779    
780     4. SQLParser: only call "OnChanging" event handler when value is different.
781    
782     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
783    
784     6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
785     that BindFields is called when the query is next activated. Avoids FieldName
786     not found error.
787    
788     7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
789     purpose and allows the programmer to define any action they want for Update, Insert
790     or Delete. This may be complex SQL (similar to a Trigger), application specific
791     filtering of updates, or use of statements such as Grant or Revoke instead of
792     normal DML. See User Manual for more information.
793    
794     IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
795    
796     1. TIBEvents: Fix uninitialised variable that could result in lost events.
797    
798     2. TIBExtract: Added support for FB3 "USAGE" privilege.
799    
800     3. TIBExtract: data formatted as Charset set "octets" is now output using
801     hexadecimal notation.
802    
803     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
804     using a simple XML format.
805    
806     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
807     grants to these objects.
808    
809     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
810     dependency problems restoring complex databases.
811    
812     7. TIBXScript: This component has been restructured to allow for the processing of
813     embedded XML in INSERT statements and to support interactive sources in addition
814     to non-interactive data sources such as files.
815    
816     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
817    
818     9. TIBXScript: ISQL compatiable Set statements are now supported:
819     SET SQL DIALECT
820     SET TERM
821     SET AUTODDL
822     SET BAIL
823     SET ECHO
824     SET COUNT
825     SET STATS
826     SET NAMES <character set>
827    
828     10. IBVersion unit added to hold current IBX Version Number information.
829    
830     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
831     and domain definitions.
832    
833     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
834     fully supported.
835    
836     13. TIBExtract: when a database dump includes data, the generator values are now also set.
837    
838     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
839    
840     IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
841    
842     See also doc/IBX4LazarusGuide.pdf for important information on
843     upgrading to IBX2.
844    
845     1. Size property of TIBStringField is now the width in characters of the field
846     and not the byte length. This applies only to multi-byte character sets such
847     as UTF8. The original approach aligned with TStringField. However, the TStringField
848     code is not recognised as a bug and hence this change to align the behaviour.
849     The TStringField change is expected in fpc 3.2.0.
850    
851     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
852     true (default) then Size property value saved in the lfm is ignored. Size is
853     always set from the dynamic information read from the database. It is unclear
854     why anyone would want to override this and set Size to false.
855    
856     3. ibxscript: should now handle correctly a Case..End statement within a procedure
857     block.
858    
859     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
860     exist when an attempt is made to connect to it (run time only) then an attempt
861     is made to create the database.
862    
863     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
864     has been successfully created as a result of a call to CreateDatabase or when
865     creating a database after it was found not to exist.
866    
867     6. DBControlGrid: a race condition could result in the wrong row image being
868     written to the cache. This has been avoided by a trip round the message
869     loop before rendering the row image.
870    
871     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
872     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
873     known to risk corrupt rendering of row images when the control is first
874     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
875     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
876    
877     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
878     a TDateEdit control located on an editor panel.
879    
880     9. TIBExtract: brought up-to-date plus many bug fixes.
881    
882     10. DBControlGrid: Removed memory leak when updating rows.
883    
884     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
885    
886     IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
887    
888     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
889     when target codepage is CP_NONE. This is a workaround for
890     http://bugs.freepascal.org/view.php?id=30622.
891    
892     2. DBLog option removed from TIBStatisticalService - not supported by server
893     since Firebird 1.5.
894    
895     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
896     similar.
897    
898     4. IBCodePage: updated mapping between codepages and character id.
899    
900     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
901     Firebird. Character sets with a char width of two are not UTF16.
902    
903     6. Strings received from the database are now always transliterated into UTF8
904     regardless of the database character set or connection character set. This
905     is for compatibility with the LCL.
906    
907     IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
908    
909     1. IBBlob: Defer reading of blob until read method called. This avoids having to
910     read in an entire blob just to get the size of the blob. General performance
911     improvement when opening datasets containing blobs.
912    
913     2. Clearing a Blob now sets the corresponding field's modified flag.
914    
915     3. IBLookupCombo: When not performing auto-complete, original query sort order
916     is now used.
917    
918     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
919     determined.
920    
921     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
922    
923     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
924     lazarus 1.6.0
925    
926     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
927     compilation error.
928    
929     IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
930    
931     1. No character set specified for connection: when a text blob is retrieved, the
932     character set is determined by looking up the native character set using then
933     Firebird API. Otherwise a text mode blob is assumed to have the same character
934     set as the connection.
935    
936     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
937     for Login Dialog returing a change to the database path.
938    
939     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
940     to be changed from that given in the TIBDatabase/TIBServer component and for the
941     entered value to be saved on a project specific basis (design time only).
942    
943     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
944     column fieldname. If they are the same then it is acts as a look up for the KeyValue
945     Otherwise, it sets the column text to the selected ListField Value.
946    
947     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
948     column width.
949    
950     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
951     and a case insensitive search is requested.
952    
953     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
954     or column ListSource.
955    
956     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
957     unprepare) when closing and the text has not changed.
958    
959     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
960     Less likely to cause a cursor re-use error on Windows.
961    
962     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
963     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
964    
965     11. TIBTreeView: Guard against nil destination on record changed
966    
967     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
968     string type with the code page set to reflect the returned field encoding after
969     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
970     earlier versions.
971    
972     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
973     will now result in transliteration to the code page specified for the Firebird driver
974     if the assigned string has a different code page. FPC 3.0.0 onwards only.
975    
976     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
977     is ignored and the lc_ctype value, when the database is opened, is set to align with
978     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
979     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
980     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
981     the GETACP is used to determine the Windows code page.
982    
983     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
984     name used as the lc_ctype when the database was opened. Only valid while the
985     Database is connected.
986    
987     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
988     id that corresponds to the DefaultCharSetName.
989    
990     IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
991    
992     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
993     path is given and database attach fails due to access permission issues on the
994     temp directory or security database, then the attach is retried with "localhost:"
995     prefixing the databasename. This should avoid problems when the database has to
996     be accessed by a local (e.g. classic) server and libfbembed is used.
997    
998     2. Windows: revised search order for Firebird DLL:
999     i. The Firebird Embedded Server in the application Directory.
1000     ii. If the FIREBIRD environment variable is set then the directory this
1001     points to is searched for the FB Client DLL and then then underlying
1002     "bin" directory.
1003     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1004     is used to locate the Firebird installation directory and the underlying
1005     "bin" directory is searched for the FB Client DLL.
1006     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1007     are searched for the FB Client DLL.
1008     v. The PATH Environment variable is used to search for the FB Client DLL.
1009     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
1010    
1011     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1012     See doc/readme.scriptengine and example applications.
1013    
1014     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1015     simplify the use of the embedded firebird server on both Linux and Windows platforms.
1016     See dpc/readme.localdatabase and example applications.
1017    
1018     5. IBDynamicGrid: Reordering on column header click should now also work for
1019     dynamic columns.
1020    
1021     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1022     between incrementing/decrementing the lock count and signalling the event.
1023    
1024     IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1025    
1026     1.3.2 was never formally released and only made available as beta copies.
1027    
1028     1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1029    
1030     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1031    
1032     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1033    
1034     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1035     i.e. when it is a calculated field
1036    
1037     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1038     This problem was due to a race condition between recalculating row heights and
1039     determining which row was selected by the mouse click. The row height calculation
1040     is now deferred by an extra trip round the message loop allowing the row to
1041     be always calculated on the current grid layout rather than risking it being
1042     calculated on the grid layout after the expanded row has been shrunk.
1043    
1044     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1045     Windows.
1046    
1047     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1048     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1049     to be determined at runtime. See doc/readme.charactersets.html.
1050    
1051     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1052     TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1053    
1054     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1055     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1056     1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1057    
1058     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1059     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1060     implies no truncation.
1061    
1062     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1063    
1064     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1065     (avoids "Not in Edit Mode" error).
1066    
1067     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1068    
1069     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1070     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1071    
1072     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1073    
1074     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1075    
1076     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1077    
1078     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1079    
1080     IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1081    
1082     1. OnCloseUp Event Handler added to TDBLookupProperties
1083    
1084     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1085     problem with row size when exception is called.
1086    
1087     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1088    
1089     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1090     in a TCustomComboBox and ignores return key if in a TCustomMemo
1091    
1092     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1093     keyed in i.e. when autocomplete not performed
1094    
1095     6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
1096     console mode applications with all LCL required functions (builtin dialogs and
1097     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
1098     not included in your project, IBX should compile and link with a console mode program.
1099     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1100     console mode application or the IDE will automatically assume that your
1101     application is GUI based. Instead, you should include the ibexpressconsolemode package.
1102    
1103     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1104     to use the built in dialogs and cursor management. IBDialogs is
1105     included by default if "ibexpress" is in your project source's "uses" clause.
1106     This should be the case for all projects created through the IDE. This is why
1107     you do not want to add the ibexpress package to console mode applications. The
1108     ibexpressconsolemode package has been created to allow console mode programs
1109     to avoid adding LCL dependencies when using IBX, while still having the
1110     unit search paths set up correctly.
1111    
1112     Existing users should check to ensure that the "ibexpress" unit is included in
1113     each project's source file (*.lpr).
1114    
1115     You may find that in order for the IDE to recognise that ibexpressconsolemode
1116     exists, you have to first open the package in the IDE and then close it. This
1117     adds it to the most recently accessed packages list. To make it permanently
1118     available, add the package name to lazarus' staticpackages.inc file.
1119    
1120     Thanks to Julio Jiménez for suggesting support of console mode.
1121    
1122     7. SQL Parser can now accept quoted strings that include new lines
1123    
1124     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1125     of text on start of edit. This is particularly useful when tabbing to a
1126     column and then inserting text.
1127    
1128     9. New Examples provided for IB Services and ISQLMonitor.
1129    
1130     10. Fix error when writing to blob streams that recorded only the last buffer
1131     write in the blob stream. In most cases, this did not cause a problem as the
1132     IB Blob Stream is written in a single write. However, with the TDBImage, write
1133     of a graphic type prefix was lost which caused a problem when the image could
1134     not be automatically recognised.
1135    
1136     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1137     already open" errors due to random numbers used for the cursor name being identical.
1138    
1139     12. IBTable: corrected error that could result in an "Index out of bounds" error
1140     when opening the table and the Primary Key is the last or only column in the
1141     table. Thanks to Rick Hoover for the fix.
1142    
1143     13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1144     of "UTF-8", and update list of available database character sets. Existing
1145     users should check the current lc_ctype setting in their applications.
1146    
1147     IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1148    
1149     1. Firebird Services: avoid List Index error when opening a service with an
1150     empty Params property.
1151    
1152     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1153     Link now set up in Loaded method - avoids occasional failure to apply
1154     SQL markup on initial open.
1155    
1156     3. "Employees" example performance improvements when scrolling.
1157    
1158     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1159     TFrame. Force recaching of selected frame to avoid GTK race (results in a
1160     random image cached).
1161    
1162     5. DBControlGrid: Should now react to changes in panel height at run time.
1163    
1164     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1165     even when further rows exist.
1166    
1167     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1168     always be derived from panel height and setting this property can cause confusion.
1169     Note for existing projects: to avoid a missing property error at run time,
1170     each form using the DBControlGrid must be opened, updated and saved in the IDE
1171     in order to remove the property value from the lfm.
1172    
1173    
1174     IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1175    
1176     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1177     call Prepare before setting parameter values.
1178    
1179     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1180    
1181     3. Code tidyup and more robust handling of dsql information result vector.
1182    
1183     4. Support for centralised handling of transaction status changes. TIBTransaction
1184     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1185     and "AfterExecQuery". The first three are called after the same event is called
1186     for an IBCustomDataSet descendent using the Transaction. The fourth is called
1187     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1188     enable monitoring of transaction status changes for a given transaction to be
1189     handled in a single place. For example, when a change to the dataset occurs
1190     an indicator can be set that shows the user that in order to save changes,
1191     the transaction should be committed. Rather than doing this per dataset, this
1192     can now be done per transaction.
1193    
1194     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1195     the dataset is scrolled. However, any changes to the current row are, by default,
1196     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1197     have a new property "DataSetCloseAction" that adds automatic posting of changes
1198     on dataset close. If this property is set to dcDiscardChanges (default) then the
1199     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1200     then IBX will attempt to post any unsaved changes before the dataset is closed
1201     (and after the BeforeClose event handler is called). The exception is when the
1202     dataset is being closed as a result of a transaction rollback. In this case,
1203     no action is taken and any unsaved changes are discarded. This avoids both
1204     unnecessary overhead and the risk that a validation error may occur in the Post
1205     raising an exception and thereby preventing a rollback.
1206    
1207     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1208     In earlier versions, the Display Width was set to the maximum byte width rather than the character
1209     width. Display Widths are now corrected by dividing by the max byte width per character.
1210     For UTF8 character sets, the byte width is four and hence the Display Width will be
1211     the byte width divided by 4. The byte width of each character set is determined
1212     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1213     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1214    
1215     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1216    
1217     8. IBLookupComboEditBox: List should now always be restored to full list when the
1218     control loses focus. Default Key press default interval reduced to 200ms.
1219    
1220     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1221     when dataset rows are less than visible rows.
1222    
1223     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1224     does not exist or DataSet is empty. More responsive on dataset open. New event
1225     OnRestorePosition. Column sort disabled if no header row.
1226    
1227     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1228     while dataset state is dsInsert. Avoids posting errors.
1229    
1230     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1231     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1232    
1233     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1234    
1235     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1236     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1237     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1238     always "posts" the current record regardless or whether or not it may be more appropriate
1239     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1240     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1241     as the first action of the "Post" method and allows the handler to convert the Post
1242     into a Cancel if that is the appropriate action on moving to a different row. This is
1243     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1244     raised here, but it may still be more appropriate to validate a post and signal
1245     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1246    
1247     15. On Unix derived systems, the Firebird library name can now be given as a colon
1248     separated list. Each library name on the list is tried in turn, in left to right
1249     order with the first found being used as the firebird library. By default, on Linux,
1250     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1251     overidden by the FBLIB environment variable or the OnGetLibraryName function.
1252    
1253     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1254     then it will still attempt to access the database via the Firebird Server and will
1255     require a username and password. If only the pathname is given, then the username
1256     and password should be omitted and the unix file permissions are used to grant
1257     access.
1258    
1259     IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1260    
1261     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1262     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1263     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1264     corresponds to a row of the linked DataSource. Any data aware control on the
1265     replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1266    
1267     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1268     When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1269     takes place during database access. This may be useful when there are performance issues with
1270     the change of cursor. Setting the property to false suppresses the change of cursor.
1271    
1272     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1273     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1274     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1275     making all changes permanent immediately rather than when the transaction is explicitly
1276     committed.
1277    
1278     4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1279     using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1280    
1281     IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1282    
1283     Development version only.
1284    
1285     IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1286    
1287     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1288     This is typically used during an "OnBeforeOpen" event handler to manipulate the
1289     "Where" and "Having" clauses to implement user specified filters of arbitrary
1290     complexity.
1291    
1292     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1293     three new data aware controls dependent on IBX and which make use of the SQL Parser.
1294     These are:
1295    
1296     - TIBLookupComboEditBox
1297     - TIBDynamicGrid
1298     - TIBTreeview
1299    
1300     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1301     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1302     to revise the available list and restrict it to items that are prefixed by the
1303     typed text (either case sensitive or case insensitive). Autoinsert allows a
1304     newly typed entry to be added to the list dataset and included in the available
1305     list items.
1306    
1307     TIBDynamicGrid is a TDBGrid descendent that provides for:
1308     - automatic resizing of selected columns to fill the available row length
1309     - automatic positioning and sizing of a "totals" control, typically at the
1310     column footer, on a per column basis.
1311     - DataSet resorting on header row click, sorting the dataset by the selected column.
1312     A second click on the same header cell reversed the sort order.
1313     - Support for a "Panel Editor". That is on clicking the indicator column, the row
1314     is automatically expanded and a panel superimposed on it. The panel can have any
1315     number of child controls, typically data aware controls with the same datasource
1316     as the grid allowing for editing of additional fields and more complex editors.
1317     - Reselection of the same row following resorting.
1318     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1319     Its properties are specified on a per column basis and allows for one or more
1320     columns to have their values selected from a list provided by a dataset.
1321     Autocomplete and autoinsert are also available. The existing picklist editor
1322     is unaffected by the extension.
1323    
1324     TIBTreeView is a data aware TCustomTreeView.
1325    
1326     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1327     zero scale will no longer return an error. An Int64 will be returned instead.
1328    
1329     4. TIBTransaction now has events for Before and After Transaction End and a new function
1330     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1331    
1332     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1333     repeated multiple times.
1334    
1335     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1336     check used to get in the way of using Stored Procedures, and "Update or Insert"
1337     statements.
1338    
1339     7. Insert, Modify and Delete property Editors now support Query Generation from
1340     Stored Procedures.
1341    
1342     8. Three new examples illustrate the use of the new IB Controls
1343    
1344    
1345     IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1346    
1347     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1348     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1349     Gabor Boros for reporting this problem and for testing the improvements).
1350    
1351     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1352     See readme.field+param.names in the doc folder.
1353    
1354     3. IBX SQL Editors will now automatically add double quotes around column names when the database
1355     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1356    
1357     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1358    
1359     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1360     actions.
1361    
1362     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1363     thanks to Yuriy Kopnin for pointing this out).
1364    
1365     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1366    
1367     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1368     for both fields and parameter setting.
1369    
1370     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1371     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1372    
1373     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1374     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1375    
1376     11. TIBTable now has a property editor for "MasterFields"
1377    
1378     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1379     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1380    
1381     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1382     of settings is unrecognised. Selecting this radio button has no effect on the settings.
1383

1385     IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1386    
1387     1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1388    
1389     IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1390    
1391     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1392     it is null. This allows for alternative user defined setting of the generator
1393    
1394     Many thanks to Julio Jiménez for this fix
1395    
1396     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1397     and suggests that the user may have forgotten to install it.
1398    
1399     IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1400    
1401     1. Conditional compilation used to limit registration of TIntegerField to
1402     Lazarus versions less than 1.1
1403    
1404     2. When a database connection is created, character set is now by default set
1405     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1406     1250 to 1254.
1407    
1408    
1409     IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1410    
1411     1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1412    
1413    
1414     IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1415    
1416     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1417     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1418    
1419     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1420     package is changed to do this (which it should do).
1421    
1422     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1423    
1424     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1425    
1426     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1427    
1428     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1429    
1430     4. Property editors should now correctly resize.
1431    
1432     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1433     (restored original functionality)
1434    
1435     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1436     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
