1 + IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
2 +
3 + 1. -c command line option added to fbsql example program. Used to set connection
4 +   character set.
5 +
6 + IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
7 +
8 + 1. Firebird 4 support added.
9 +
10 + 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
11 +   extended precision NUMERIC fields are supported.
12 +
13 + 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
14 +
15 + 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
16 +   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
17 +
18 + 5. IBExtract now supports FB4 enhancements:
19 +   - new data types as above
20 +   - Identity column extensions
21 +   - Default user role
22 +   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
23 +   - Internal Functions
24 +
25 + 6. IBExtract: new event: OnExtractLines.
26 +
27 + 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
28 +
29 + 8. IBXServices: Server version no. parsing now allows any letter before major version number
30 +   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
31 +
32 + 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
33 +   format for rendering a time zone.
34 +
35 + 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
36 +     to convert TIME WITH TIME ZONE data type values to and from GMT.
37 +
38 + 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
39 +    IIBGUIInterface and IIBTimerInf respectively.
40 +
41 + 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
42 +    now accessible as properties of TIBDatabase and TIBTransaction respectively.
43 +
44 + 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
45 +    truncated to its fixed character width rather than being right padded with
46 +    white space to the maximum data size.
47 +
48 + 14. TIBTable.Empty table. In additional to deleting all records in the underlying
49 +    table, the internal buffers are now also flushed ensuring that the TIBTable is
50 +    also empty.
51 +
52 + 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
53 +
54 + 16. TIBXControlService descendents: DatabaseName may now be set using a database
55 +    connect string. The database name is extracted from the connect string.
56 +
57 + 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
58 +
59 + 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
60 +
61 + 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
62 +    not being present as required.
63 +
64 + 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
65 +    version that can be customised to work with other database drivers.
66 +
67 + 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
68 +    unnecessary CR at end of line on Unix platforms.
69 +
70 + 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
71 +    seconds in order to reduce risk of message loss.
72 +
73 + 23. ISQLMonitor: read and write count statistics now available via:
74 +      property TIBSQLMonitor.ReadCount;
75 +      IIBSQLMonitorHook.GetWriteCount: integer;
76 +
77 + 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
78 +
79 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
80 +
81 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
82 +    number of UTF8 characters exceeds the string size then string is truncated
83 +    to the maximum string size. This is  usually a problem with fixed width columns
84 +    right padded with white space.
85 +
86 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
87 +    If SQLFiltered is set then when a dataset is opened, each line in the
88 +    SQLFilterParams property is assumed to be a SQL condition clause and
89 +    ANDed into the Where clause of the SQL Select statement provided as a
90 +    dataset property. Each such SQL condition thus acts as an additional filter
91 +    on the dataset.
92 +
93 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
94 +    side filters).
95 +
96 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
97 +   text matches complete entry.
98 +
99 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
100 +   dataset are active (avoids risk of access violation if master is inactive)
101 +
102 + 6. TIBEvents: Registered property can now be set at design time even if database not open
103 +
104 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
105 +   This should prevent "spillover" of events between sessions.
106 +
107 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
108 +   This should ensure that the internal buffer is set up correctly and avoids
109 +   a duplicate initial row.
110 +
111 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
112 +   That is, the DataSize should be the field size * character set width. The
113 +   value returned by DataSize is now the same as the Dataset buffer size reserved
114 +   for the field.
115 +
116 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
117 +
118 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
119 +    and vice-versa. This may result in an exception being raised (correctly) for
120 +    older programs when using dataset fields added to a form and the database has been
121 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
122 +    In such cases, the field needs to be deleted in the IDE fields editor and then
123 +    added back in.
124 +
125 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
126 +    false if query contains only white space and not just empty.
127 +
128 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
129 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
130 +    is cancelled.
131 +
132 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
133 +    called on a null field.
134 +
135 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
136 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
137 + set.
138 +
139 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
140 +    a cached update is applied and an exception is raised.
141 +
142 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
143 +
144 + 17. Console Mode Local Database support: backup/restore should now work correctly.
145 +
146 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
147 +    possible and an exception raised.
148 +
149 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
150 +    below this version no. and upgrade not possible.
151 +
152 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
153 +
154 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
155 +    not SQL Identifiers are now supported.
156 +
157 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
158 +    passed to the Firebird engine for execution.
159 +
160 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
161 +    is made to scroll back.
162 +
163 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
164 +
165 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
166 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
167 +
168 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
169 +   validated. If no match is found in the list of field names and the database has
170 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
171 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
172 +
173 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
174 +   with fpc 3.2.
175 +
176 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
177 +
178 +
179 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
180 +   and is used to override the default settings in the client side "firebird.conf" This
181 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
182 +   Each line of the string list should be a setting in the same format as "firebird.conf".
183 +   For example "WireCompression = true" in order to request wire compression on the client side.
184 +
185 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
186 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
187 +   also require a compatible setting in the server side "firebird.conf". For example
188 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
189 +   compression to be used.
190 +
191 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
192 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
193 +   ibx/examples/dbinfo for examples of how to display this information.
194 +
195 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
196 +   is a "convenience" property. If set the "WireCompression=true" is added to the
197 +   ConfigOverrides. If unchecked then this setting is removed.
198 +
199 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
200 +   not "INT64".
201 +
202 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
203 +   These are:
204 +    property TimestampFormat: string;
205 +    property DateFormat: string;
206 +    property TimeFormat: string;
207 +
208 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
209 +   DATETIME and TIME. The format strings use the standard FPC date/time format
210 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
211 +
212 +   If any of the above properties are set to an empty string, then the locale default
213 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
214 +   locale default is extended by appending '.zzz' to include milliseconds.
215 +
216 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
217 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
218 +
219 + 5. New published property for TIBCSVDataOut:
220 +     property QuoteStrings: boolean (default true)
221 +
222 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
223 +   used to delimit each and every string in the output.
224 +
225 + 6. New published properties for TIBCSVDataOut:
226 +    property FieldSeparator: string;
227 +    property HeaderSeparator: string;
228 +
229 +   Respectively, these provide the separator character(s) used to separate fields
230 +   in data and header rows. Both default to ','.
231 +
232 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
233 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
234 +    property OnFormatTextString;
235 +
236 +   This event handler can be used to process text strings before they are included
237 +   in the output e.g. to replace unprintable characters with alternative strings.
238 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
239 +
240 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
241 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
242 +   and without raising and exception if it does not.
243 +
244 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
245 +   consistency with SQL queries.
246 +
247 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
248 +    When true, SQL statement parameter names are parsed case sensitive. Note for
249 +    TIBDataSet only applies to Select query.
250 +
251 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
252 +    an IDE exception.
253 +
254 + 12. LocalDBSupport: initial database creation should now work correctly
255 +    when the schema source is an sql file.
256 +
257 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
258 +    when defined, this handler will be called by the internal TIBXScript during
259 +    initial database creation when the schema source is an sql file and may be used
260 +    to provide a visual indication of progress in console mode.
261 +
262 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
263 +    to true while a new local database is being created and its schema populated.
264 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
265 +    when the database is disconnected/connected during the create DB procedure.
266 +
267 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
268 +    are now always ignored and replaced by the user name and password provided as
269 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
270 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
271 +    completely ignored if this property is true.
272 +
273 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
274 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
275 +    ImageIndex and SelectImageIndex values on AddNode.
276 +
277 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
278 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
279 +    the same database connection.
280 +
281 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
282 +    if provided, this should be an conditional SQL expression suitable for
283 +    including in an SQL Select statement "where" clause. If non-empty and the
284 +    "Filtered" property is true then the SQL expression provided as the value of
285 +    the "Filter" property is "ANDed" with any existing condition statement
286 +    in the SQL statement's "Where" clause.
287 +
288 +    If the "Filter" property is set at run time, the "Filtered" property is true
289 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
290 +
291 +    The "Filter" condition may include IBX style parameters. In which case, their
292 +    value must be set by the dataset's "OnBeforeOpen" event handler.
293 +
294 +    This is a public property for TIBDataSet and TIBQuery query and intended for
295 +    use at run time.
296 +
297 +    Note: The property is a published property of TIBTable. The TIBTable functionality
298 +    is unaffected by this change.
299 +
300 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
301 +
302 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
303 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
304 +   mode apps.
305 +
306 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
307 +   statement. This avoids problems if "Execute Block" is used as the Query.
308 +
309 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
310 +   internal SQL tokeniser routines.
311 +
312 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
313 +   as a select statement, with or without CTEs.
314 +
315 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
316 +
317 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
318 +   internal SQL tokeniser routines.
319 +
320 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
321 +    being raised for valid set statements processed by a data formatter.
322 +
323 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
324 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
325 +   the path of the Firebird Library used by the database/services connection.
326 +
327 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
328 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
329 +   services connection.
330 +
331 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
332 +   or param name is not a valid SQL identifier.
333 +
334 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
335 +    view of whether the text box should be editable when no DataSource is specified.
336 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
337 +    ReadOnly is false, the text box is editable when no DataSource is specified.
338 +
339 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
340 +    the FBLIB environment variable. If you do not want to permit this then you
341 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
342 +    this setting.
343 +
344 + IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
345 +
346 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
347 +   Utf8EscapeControlChars
348 +
349 + IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
350 +
351 + IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
352 + all previous copies of the IBX source code tree before installing this release.
353 +
354 + The IBX packages used by most users have not changed, with one exception. The
355 + IBServices unit has been moved to the package iblegacyServices.lpk. To continue
356 + to use the IBServices unit in your applications, please add the iblegacyServices
357 + to the list of dependencies. To do this, open the Project Inspector and select
358 + Add->New Requirement and select "ibLegacyServices" from the list of available
359 + packages.
360 +
361 + 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
362 +   the IBServices unit providing what is intended to be a clearer and easier to
363 +   use set of IB Services components. See Chapter 10 of the IBX User Guide for
364 +   more information and the guide to "Firebird Service Management Using IBX".
365 +   As indicated above, the legacy services components are still available and
366 +   provided in a separate package. There is no need to update working applications
367 +   using the older versions except for an additional package dependency.
368 +
369 + 2. The IBX packages and source code tree have been re-organised in an attempt to
370 +   finally get rid of the "duplicate ppu" warnings. This re-organisation should
371 +   not affect existing users. Section 2.3 of the IBX User Guide describes the
372 +   new set of IBX packages.
373 +
374 + 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
375 +   updated to use the new Services API components.
376 +
377 + 4. The iblocal package has been updated to use the new Services API components.
378 +
379 + 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
380 +   TIBXSecurityService. It had been wrongly classified in the previous version
381 +   as a per database configuration item. It is global to a server and hence
382 +   correctly positioned as part of the Security Package. In the DBAdmin example,
383 +   the setting has moved to the mappings page.
384 +
385 + 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
386 +   are ignored.
387 +
388 + 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
389 +   closed before the database is dropped. Before and After Disconnect event handlers
390 +   are also fired.
391 +
392 + 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
393 +   is started and not just the first time.
394 +
395 + 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
396 +   depenendency with comp type.
397 +
398 + 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
399 +
400 + 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
401 +    then this is recognised and not ignored.
402 +
403 + 12. TIBDataSet, TIBQuery, TIBTable: additions:
404 +    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
405 +    function GetPerfStatistics(var stats: TPerfCounters): boolean;
406 +    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
407 +
408 +    GetRowsAffected returns the affected row counts from the last insert/update/delete
409 +    if EnableStatistics = true then GetPerfStatistics returns the current stats
410 +    counters for the select query. Note: stats accumulate after each fetch from
411 +    the database. To get total query cost after open, call the "Last" method
412 +    and then GetPerfStatistics.
413 +
414 +    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
415 +
416 + 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
417 +    in parenthesises.
418 +
419 + 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
420 +    SQL identifiers are always delimited by double quotes. If false, then they are
421 +    only delimited if the identifier is a reserved word, contains lower case or special
422 +    characters. Set this property to true to retain previous behaviour.
423 +
424 + 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
425 +    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
426 +
427 + 16. TIBDataSet, TIBQuery, TIBTable: addition:
428 +       property MasterDetailDelay: integer {defaults to zero}
429 +
430 +    When non-zero and the dataset is a detail table referencing a master table
431 +    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
432 +    then a synchronisation delay is added (in milliseconds) between the master
433 +    row changing and the detail dataset being re-opened. If the master dataset
434 +    is scrolled before the delay expires then the delay is reset. This can be used
435 +    to avoid performance overheads when scrolling through a large master dataset.
436 +
437 +    Note: uses fptimer and hence requires a thread manager. Under Linux the
438 +    chreads unit must be included in your project. TTimer is not used in order
439 +    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
440 +
441 + 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
442 +    with Extract Option eoDatabase.
443 +
444 + 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
445 +    When a deLayoutChanged event is reported on the ListSource dataset, the
446 +    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
447 +    relationship with the control's datasource (master).
448 +
449 + 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
450 +
451 + 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
452 +    stubs. Pedantic fix really, as procedures output in dependency order anyway.
453 +
454 + 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
455 +    DDL (Firebird 3 and later only).
456 +
457 + 22. TIBLookupComboBox Autocomplete Fixes:
458 +    i. Only appended text is now selected after autocomplete.
459 +    ii. Uppercase keys no longer ignored for autocomplete.
460 +    iii. Retain Prefix case is now honoured correctly.
461 +    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
462 +        before autocomplete performed. i.e. behaviour now the same as when
463 +        no DataSource assigned.
464 +
465 + 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
466 +    between SQL statements.
467 +
468 + 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
469 +    ObjectNames are converted to upper case before matching against metadata object
470 +    names, unless the objectname is delimited by double quotes, in which case, the
471 +    double quotes are removed and the remaining string is used (unmodified) to match
472 +    against the metadata object name.
473 +
474 +    If true then the ObjectName is used as is without modification and matched
475 +    against the metadata object name. No attempt is made to remove double quotes.
476 +
477 + 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
478 +    with eoTrigger, these extract types can be used to select only Database Triggers,
479 +    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
480 +
481 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
482 +    statement separate character is now reset to the default (';').
483 +
484 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
485 +
486 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
487 +    a commit or reconnect statement and instead activated only when next SQL statement
488 +    is executed.
489 +
490 + 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
491 +
492 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
493 +    converting statement to upper case.
494 +
495 + 31. TIBExtract: metadata comments now supported. New published property
496 +    IncludeMetaDataComments (default true). If true then metadata comments included
497 +    in extracted DDL. New Extract Object member eoComments. This may be used with
498 +    ExtractObject method to list all metadata comments.
499 +
500 + 32. TIBExtract: ListObjectNames method added.
501 +
502 + 33. Updated Database component editor to support additional connection string
503 +    types.
504 +
505 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
506 +
507 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
508 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
509 + RELEASE.
510 +
511 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
512 +
513 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
514 +
515 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
516 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
517 +   information). However, this is also a very useful mechanism for returning updated computed by
518 +   column values. Values returned as a result of executing an Insert or Update statement
519 +   replace existing values in the current row for each corresponding column.
520 +
521 +   Previously, if a dataset's select query included read only (computed by) fields then
522 +   an automatic row refresh was performed after an insert or update query had been processed,
523 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
524 +   that an automatic refresh is no longer performed if an insert or update query contains
525 +   a returning clause that updates one or more fields on the current row. A full row
526 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
527 +   field values and the select query contains read only fields. Use of Insert/update
528 +   returning should be significantly more efficient than executing a refresh query.
529 +
530 +   This behaviour change is intended to be backwards compatible and there should be no need to change
531 +   existing programs, other than to improve performance by using the new capability.
532 +
533 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
534 +   they are called when the dataset row is being deleted, there is no value in
535 +   updating the current record from the query result. Instead, a new event handler
536 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
537 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
538 +   by the query. The event handler can then interrogate the query results and
539 +   perform whatever action is necessary. For example to confirm, to the user,
540 +   the deletion of a row with the returned values.
541 +
542 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
543 +   any Computed By or Identity Columns. The IBTables example has been updated to
544 +   illustrate the computation of the employee Full Name on update.
545 +
546 + 5. TIBTable: The GeneratorField property is now published.
547 +
548 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
549 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
550 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
551 +   each Identity column after the insert is executed.
552 +
553 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
554 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
555 +   Insert..Returning clause.
556 +
557 + 8. TIBGenerator: small performance improvement by not preparing query each time
558 +   a new value is generated.
559 +
560 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
561 +
562 + 10. Property editors will now sync table name to a System Table when "Include System
563 +    Tables" is selected and the query is for a System Table.
564 +
565 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
566 +    values are no longer converted to milliseconds from TDateTime and then back again
567 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
568 +
569 + 12. Property Editors handling of Stored Procedures.
570 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
571 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
572 +      query).
573 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
574 +
575 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
576 +    can be used to select a package. If non-empty, the stored procedure name is
577 +    expected to be a stored procedure defined in the specified package and the
578 +    generated SQL will be as required for a stored procedure located in a package.
579 +
580 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
581 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
582 +    which a stored procedure can be selected. With no package name selected, non-package
583 +    stored procedures are listed.
584 +
585 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
586 +    for password on reconnect.
587 +
588 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
589 +    and character set name.
590 +
591 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
592 +    DB info lookups"
593 +
594 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
595 +
596 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
597 +
598 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
599 +    parameters. This stops an exception being raised when the field cannot be
600 +    located in the record buffer.
601 +
602 + 21. Property Editors now automatically include System Tables when opened and when the query table
603 +    is a System Table.
604 +
605 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
606 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
607 +
608 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
609 +    add the SPB item isc_spb_expected_db. This names a database using
610 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
611 +    database. examples/services re-written to illustrate use of "expected_db".
612 +
613 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
614 +    This avoids truncated backups when the server returns a timeout (busy) response.
615 +
616 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
617 +
618 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
619 +    databasenames. These are respectively expanded to the local system's temp directory
620 +    (including trailing delimiter) or to a prescribed data directory (including
621 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
622 +    in the user's home directory. The hidden directory name is either the string returned
623 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
624 +    Under Windows, the directory is the same as the Data Directory as decribed
625 +    above but instead prefixed by the User's application data path. These may be
626 +    used to improve application portability for Personal Databases.
627 +
628 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
629 +    this has not worked for a long time and is not useful either. FieldDefs should be
630 +    managed using the Fields Editor as with any other dataset. To access the fields
631 +    editor for a TIBTable component, double click on the component. The fields editor
632 +    is then displayed.
633 +
634 + 28. TIBDatabaseInfo: new properties/function
635 +     * DateDBCreated (returns date/time database created)
636 +     * TransactionCount (returns no. of active transactions)
637 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
638 +     * PagesFree (Firebird 3 or later)
639 +     * PagesUsed (Firebird 3 or later)
640 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
641 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
642 +
643 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
644 +
645 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
646 +
647 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
648 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
649 +
650 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
651 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
652 +    firing during backup and restore.
653 +
654 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
655 +    for verbose output using the new property "StatisticsRequested".
656 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
657 +
658 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
659 +
660 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
661 +    palette. This uses the online validation feature added in Firebird 2.5. The
662 +    services's properties enable inclusion/exclusion of tables and indexes using
663 +    regular expressions. See.
664 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
665 +
666 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
667 +    option on a database.
668 +
669 + 37. TIBCustomService: Assign method implemented to allow copying of service login
670 +    context between service API components. "Detach" method now only detaches
671 +    service when last reference to the service interface detaches. Tidy up of
672 +    code for SetActive and Attach methods including password hiding.
673 +
674 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
675 +    and used to determine the auth method and protocol used for the connection.
676 +
677 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
678 +    a Create Database Statement generated by IBX.
679 +
680 + 40. All IBServices now have an additional published property "PortNo". This may
681 +    be set to a non-standard port number when necessary. If zero then the default
682 +    port number is used.
683 +
684 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
685 +    and not just the mouse.
686 +
687 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
688 +
689 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
690 +    image index and selected image index for each node to be set from a database field.
691 +
692 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
693 +    then database schema includes grants to all users. If not present then the
694 +    only user grants included are those to User PUBLIC.
695 +
696 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
697 +    and child nodes in dataset.
698 +
699 +
700 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
701 +
702 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
703 +   changes.
704 +
705 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
706 +   Bug could result in truncated multi-byte character set values.
707 +
708 + 3. Changes consequential on moving fbintf character set utility functions from
709 +   IFirebirdAPI to IAttachment.
710 +
711 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
712 +
713 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
714 +   results in autocomplete ignoring prefix text.
715 +
716 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
717 +   entering a new name into the text box.
718 +
719 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
720 +   Firebird rather than recomputing it.
721 +
722 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
723 +   screen centre. Previously some were "poDesigned" which may be inappropriate
724 +   for multi monitor desktops.
725 +
726 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
727 +
728 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
729 +    a transaction and always reset the object.
730 +
731 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
732 +
733 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
734 +
735 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
736 +    to a gbak format archive.
737 +
738 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
739 +
740 + 16. IBLocaldb: Drop database if error creating an empty database.
741 +
742 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
743 +    unless selected node not in current dataset.
744 +
745 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
746 +    to TIBCustomService, and IBlocalDB code tidy up.
747 +
748 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
749 +    behaviour due to uninitialised variable.
750 +
751 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
752 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
753 +
754 + 21. IBSQL: When Database changed ensure that all resources are freed.
755 +
756 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
757 +
758 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
759 +    * Line Wrap on SQL Token boundaries (on user command)
760 +    * auto-complete table names in drop down list of table names
761 +    * Double click on tablename or field name adds to SQL text
762 +
763 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
764 +
765 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
766 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
767 +    workaround for a problem in fpc 3.0.4 win64).
768 +
769 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
770 +
771 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
772 +
773 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
774 +
775 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
776 +   include remote system name.
777 +
778 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
779 +   tables when data included in output.
780 +
781 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
782 +   and timing information to be written to stdout. This may be used to locate
783 +   performance bottlenecks.
784 +
785 + 4. SQLParser: only call "OnChanging" event handler when value is different.
786 +
787 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
788 +
789 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
790 +   that BindFields is called when the query is next activated. Avoids FieldName
791 +   not found error.
792 +
793 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
794 +   purpose and allows the programmer to define any action they want for Update, Insert
795 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
796 +   filtering of updates, or use of statements such as Grant or Revoke instead of
797 +   normal DML. See User Manual for more information.
