3 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
4 >    not SQL Identifiers are now supported.
5 >
6 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
7 >    passed to the Firebird engine for execution.
8 >
9 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
10 >    is made to scroll back.
11 >
12 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
13 >
14 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
15 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
16 >
17 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
18 >   validated. If no match is found in the list of field names and the database has
19 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
20 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
21 >
22 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
23 >   with fpc 3.2.

26 >
27 >
28 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
29 >   and is used to override the default settings in the client side "firebird.conf" This
30 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
31 >   Each line of the string list should be a setting in the same format as "firebird.conf".
32 >   For example "WireCompression = true" in order to request wire compression on the client side.
33 >
34 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
35 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
36 >   also require a compatible setting in the server side "firebird.conf". For example
37 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
38 >   compression to be used.
39 >
40 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
41 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
42 >   ibx/examples/dbinfo for examples of how to display this information.
43 >
44 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
45 >   is a "convenience" property. If set the "WireCompression=true" is added to the
46 >   ConfigOverrides. If unchecked then this setting is removed.
47 >
48 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
49 >   not "INT64".
50 >
51 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
52 >   These are:
53 >    property TimestampFormat: string;
54 >    property DateFormat: string;
55 >    property TimeFormat: string;
56 >
57 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
58 >   DATETIME and TIME. The format strings use the standard FPC date/time format
59 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
60 >
61 >   If any of the above properties are set to an empty string, then the locale default
62 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
63 >   locale default is extended by appending '.zzz' to include milliseconds.
64 >
65 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
66 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
67 >
68 > 5. New published property for TIBCSVDataOut:
69 >     property QuoteStrings: boolean (default true)
70 >
71 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
72 >   used to delimit each and every string in the output.
73 >
74 > 6. New published properties for TIBCSVDataOut:
75 >    property FieldSeparator: string;
76 >    property HeaderSeparator: string;
77 >
78 >   Respectively, these provide the separator character(s) used to separate fields
79 >   in data and header rows. Both default to ','.
80 >
81 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
82 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
83 >    property OnFormatTextString;
84 >
85 >   This event handler can be used to process text strings before they are included
86 >   in the output e.g. to replace unprintable characters with alternative strings.
87 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
88 >
89 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
90 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
91 >   and without raising and exception if it does not.
92 >
93 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
94 >   consistency with SQL queries.
95 >
96 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
97 >    When true, SQL statement parameter names are parsed case sensitive. Note for
98 >    TIBDataSet only applies to Select query.
99 >
100 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
101 >    an IDE exception.
102 >
103 > 12. LocalDBSupport: initial database creation should now work correctly
104 >    when the schema source is an sql file.
105 >
106 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
107 >    when defined, this handler will be called by the internal TIBXScript during
108 >    initial database creation when the schema source is an sql file and may be used
109 >    to provide a visual indication of progress in console mode.
110 >
111 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
112 >    to true while a new local database is being created and its schema populated.
113 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
114 >    when the database is disconnected/connected during the create DB procedure.
115 >
116 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
117 >    are now always ignored and replaced by the user name and password provided as
118 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
119 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
120 >    completely ignored if this property is true.
121 >
122 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
123 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
124 >    ImageIndex and SelectImageIndex values on AddNode.
125 >
126 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
127 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
128 >    the same database connection.
129 >
130 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
131 >    if provided, this should be an conditional SQL expression suitable for
132 >    including in an SQL Select statement "where" clause. If non-empty and the
133 >    "Filtered" property is true then the SQL expression provided as the value of
134 >    the "Filter" property is "ANDed" with any existing condition statement
135 >    in the SQL statement's "Where" clause.
136 >
137 >    If the "Filter" property is set at run time, the "Filtered" property is true
138 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
139 >
140 >    The "Filter" condition may include IBX style parameters. In which case, their
141 >    value must be set by the dataset's "OnBeforeOpen" event handler.
142 >
143 >    This is a public property for TIBDataSet and TIBQuery query and intended for
144 >    use at run time.
145 >
146 >    Note: The property is a published property of TIBTable. The TIBTable functionality
147 >    is unaffected by this change.
148 >
149 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
150 >
151 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
152 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
153 >   mode apps.
154 >
155 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
156 >   statement. This avoids problems if "Execute Block" is used as the Query.
157 >
158 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
159 >   internal SQL tokeniser routines.
160 >
161 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
162 >   as a select statement, with or without CTEs.
163 >
164 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
165 >
166 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
167 >   internal SQL tokeniser routines.
168 >
169 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
170 >    being raised for valid set statements processed by a data formatter.
171 >
172 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
173 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
174 >   the path of the Firebird Library used by the database/services connection.
175 >
176 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
177 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
178 >   services connection.
179 >
180 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
181 >   or param name is not a valid SQL identifier.
182 >
183 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
184 >    view of whether the text box should be editable when no DataSource is specified.
185 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
186 >    ReadOnly is false, the text box is editable when no DataSource is specified.
187 >
188 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
189 >    the FBLIB environment variable. If you do not want to permit this then you
190 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
191 >    this setting.
192 >
193 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
194 >
195 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
196 >   Utf8EscapeControlChars
197 >
198 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
199 >
200 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
201 > all previous copies of the IBX source code tree before installing this release.
202 >
203 > The IBX packages used by most users have not changed, with one exception. The
204 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
205 > to use the IBServices unit in your applications, please add the iblegacyServices
206 > to the list of dependencies. To do this, open the Project Inspector and select
207 > Add->New Requirement and select "ibLegacyServices" from the list of available
208 > packages.
209 >
210 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
211 >   the IBServices unit providing what is intended to be a clearer and easier to
212 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
213 >   more information and the guide to "Firebird Service Management Using IBX".
214 >   As indicated above, the legacy services components are still available and
215 >   provided in a separate package. There is no need to update working applications
216 >   using the older versions except for an additional package dependency.
217 >
218 > 2. The IBX packages and source code tree have been re-organised in an attempt to
219 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
220 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
221 >   new set of IBX packages.
222 >
223 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
224 >   updated to use the new Services API components.
225 >
226 > 4. The iblocal package has been updated to use the new Services API components.
227 >
228 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
229 >   TIBXSecurityService. It had been wrongly classified in the previous version
230 >   as a per database configuration item. It is global to a server and hence
231 >   correctly positioned as part of the Security Package. In the DBAdmin example,
232 >   the setting has moved to the mappings page.
233 >
234 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
235 >   are ignored.
236 >
237 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
238 >   closed before the database is dropped. Before and After Disconnect event handlers
239 >   are also fired.
240 >
241 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
242 >   is started and not just the first time.
243 >
244 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
245 >   depenendency with comp type.
246 >
247 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
248 >
249 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
250 >    then this is recognised and not ignored.
251 >
252 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
253 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
254 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
255 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
256 >
257 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
258 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
259 >    counters for the select query. Note: stats accumulate after each fetch from
260 >    the database. To get total query cost after open, call the "Last" method
261 >    and then GetPerfStatistics.
262 >
263 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
264 >
265 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
266 >    in parenthesises.
267 >
268 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
269 >    SQL identifiers are always delimited by double quotes. If false, then they are
270 >    only delimited if the identifier is a reserved word, contains lower case or special
271 >    characters. Set this property to true to retain previous behaviour.
272 >
273 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
274 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
275 >
276 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
277 >       property MasterDetailDelay: integer {defaults to zero}
278 >
279 >    When non-zero and the dataset is a detail table referencing a master table
280 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
281 >    then a synchronisation delay is added (in milliseconds) between the master
282 >    row changing and the detail dataset being re-opened. If the master dataset
283 >    is scrolled before the delay expires then the delay is reset. This can be used
284 >    to avoid performance overheads when scrolling through a large master dataset.
285 >
286 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
287 >    chreads unit must be included in your project. TTimer is not used in order
288 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
289 >
290 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
291 >    with Extract Option eoDatabase.
292 >
293 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
294 >    When a deLayoutChanged event is reported on the ListSource dataset, the
295 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
296 >    relationship with the control's datasource (master).
297 >
298 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
299 >
300 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
301 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
302 >
303 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
304 >    DDL (Firebird 3 and later only).
305 >
306 > 22. TIBLookupComboBox Autocomplete Fixes:
307 >    i. Only appended text is now selected after autocomplete.
308 >    ii. Uppercase keys no longer ignored for autocomplete.
309 >    iii. Retain Prefix case is now honoured correctly.
310 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
311 >        before autocomplete performed. i.e. behaviour now the same as when
312 >        no DataSource assigned.
313 >
314 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
315 >    between SQL statements.
316 >
317 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
318 >    ObjectNames are converted to upper case before matching against metadata object
319 >    names, unless the objectname is delimited by double quotes, in which case, the
320 >    double quotes are removed and the remaining string is used (unmodified) to match
321 >    against the metadata object name.
322 >
323 >    If true then the ObjectName is used as is without modification and matched
324 >    against the metadata object name. No attempt is made to remove double quotes.
325 >
326 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
327 >    with eoTrigger, these extract types can be used to select only Database Triggers,
328 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
329 >
330 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
331 >    statement separate character is now reset to the default (';').
332 >
333 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
334 >
335 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
336 >    a commit or reconnect statement and instead activated only when next SQL statement
337 >    is executed.
338 >
339 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
340 >
341 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
342 >    converting statement to upper case.
343 >
344 > 31. TIBExtract: metadata comments now supported. New published property
345 >    IncludeMetaDataComments (default true). If true then metadata comments included
346 >    in extracted DDL. New Extract Object member eoComments. This may be used with
347 >    ExtractObject method to list all metadata comments.
348 >
349 > 32. TIBExtract: ListObjectNames method added.
350 >
351 > 33. Updated Database component editor to support additional connection string
352 >    types.
353 >
354 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
355 >
356 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
357 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
358 > RELEASE.
359 >
360 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
361 >
362 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
363 >
364 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
365 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
366 >   information). However, this is also a very useful mechanism for returning updated computed by
367 >   column values. Values returned as a result of executing an Insert or Update statement
368 >   replace existing values in the current row for each corresponding column.
369 >
370 >   Previously, if a dataset's select query included read only (computed by) fields then
371 >   an automatic row refresh was performed after an insert or update query had been processed,
372 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
373 >   that an automatic refresh is no longer performed if an insert or update query contains
374 >   a returning clause that updates one or more fields on the current row. A full row
375 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
376 >   field values and the select query contains read only fields. Use of Insert/update
377 >   returning should be significantly more efficient than executing a refresh query.
378 >
379 >   This behaviour change is intended to be backwards compatible and there should be no need to change
380 >   existing programs, other than to improve performance by using the new capability.
381 >
382 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
383 >   they are called when the dataset row is being deleted, there is no value in
384 >   updating the current record from the query result. Instead, a new event handler
385 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
386 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
387 >   by the query. The event handler can then interrogate the query results and
388 >   perform whatever action is necessary. For example to confirm, to the user,
389 >   the deletion of a row with the returned values.
390 >
391 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
392 >   any Computed By or Identity Columns. The IBTables example has been updated to
393 >   illustrate the computation of the employee Full Name on update.
394 >
395 > 5. TIBTable: The GeneratorField property is now published.
396 >
397 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
398 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
399 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
400 >   each Identity column after the insert is executed.
401 >
402 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
403 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
404 >   Insert..Returning clause.
405 >
406 > 8. TIBGenerator: small performance improvement by not preparing query each time
407 >   a new value is generated.
408 >
409 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
410 >
411 > 10. Property editors will now sync table name to a System Table when "Include System
412 >    Tables" is selected and the query is for a System Table.
413 >
414 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
415 >    values are no longer converted to milliseconds from TDateTime and then back again
416 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
417 >
418 > 12. Property Editors handling of Stored Procedures.
419 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
420 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select

422 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
423 >
424 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
425 >    can be used to select a package. If non-empty, the stored procedure name is
426 >    expected to be a stored procedure defined in the specified package and the

428 >
429 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
430 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
431 >    which a stored procedure can be selected. With no package name selected, non-package

434 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
435 >    for password on reconnect.
436 >
437 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
438 >    and character set name.
439 >
440 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
441 >    DB info lookups"
442 >
443 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
444 >
445 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
446 >
447 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
448 >    parameters. This stops an exception being raised when the field cannot be

453 >
454 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
455 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
456 >
457 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
458 >    add the SPB item isc_spb_expected_db. This names a database using
459 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
460 >    database. examples/services re-written to illustrate use of "expected_db".
461 >
462 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
463 >    This avoids truncated backups when the server returns a timeout (busy) response.
464 >
465 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
466 >
467 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
468 >    databasenames. These are respectively expanded to the local system's temp directory
469 >    (including trailing delimiter) or to a prescribed data directory (including
470 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
471 >    in the user's home directory. The hidden directory name is either the string returned
472 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
473 >    Under Windows, the directory is the same as the Data Directory as decribed
474 >    above but instead prefixed by the User's application data path. These may be
475 >    used to improve application portability for Personal Databases.
476 >
477 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
478 >    this has not worked for a long time and is not useful either. FieldDefs should be
479 >    managed using the Fields Editor as with any other dataset. To access the fields
480 >    editor for a TIBTable component, double click on the component. The fields editor
481 >    is then displayed.
482 >
483 > 28. TIBDatabaseInfo: new properties/function
484 >     * DateDBCreated (returns date/time database created)
485 >     * TransactionCount (returns no. of active transactions)
486 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
487 >     * PagesFree (Firebird 3 or later)
488 >     * PagesUsed (Firebird 3 or later)
489 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
490 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
491 >
492 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
493 >
494 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
495 >
496 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
497 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
498 >
499 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
500 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
501 >    firing during backup and restore.
502 >
503 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
504 >    for verbose output using the new property "StatisticsRequested".

506 >
507 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
508 >
509 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
510 >    palette. This uses the online validation feature added in Firebird 2.5. The
511 >    services's properties enable inclusion/exclusion of tables and indexes using
512 >    regular expressions. See.

514 >
515 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
516 >    option on a database.
517 >
518 > 37. TIBCustomService: Assign method implemented to allow copying of service login
519 >    context between service API components. "Detach" method now only detaches
520 >    service when last reference to the service interface detaches. Tidy up of
521 >    code for SetActive and Attach methods including password hiding.
522 >
523 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
524 >    and used to determine the auth method and protocol used for the connection.
525 >
526 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
527 >    a Create Database Statement generated by IBX.
528 >
529 > 40. All IBServices now have an additional published property "PortNo". This may
530 >    be set to a non-standard port number when necessary. If zero then the default
531 >    port number is used.
532 >
533 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
534 >    and not just the mouse.
535 >
536 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
537 >
538 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
539 >    image index and selected image index for each node to be set from a database field.
540 >
541 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
542 >    then database schema includes grants to all users. If not present then the
543 >    only user grants included are those to User PUBLIC.
544 >
545 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
546 >    and child nodes in dataset.

550 >
551 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
552 >   changes.
553 >
554 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
555 >   Bug could result in truncated multi-byte character set values.
556 >
557 > 3. Changes consequential on moving fbintf character set utility functions from
558 >   IFirebirdAPI to IAttachment.
559 >
560 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
561 >
562 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
563 >   results in autocomplete ignoring prefix text.
564 >
565 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
566 >   entering a new name into the text box.
567 >
568 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
569 >   Firebird rather than recomputing it.
570 >
571 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
572 >   screen centre. Previously some were "poDesigned" which may be inappropriate
573 >   for multi monitor desktops.
574 >
575 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
576 >
577 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
578 >    a transaction and always reset the object.
579 >
580 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
581 >
582 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
583 >
584 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
585 >    to a gbak format archive.
586 >
587 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
588 >
589 > 16. IBLocaldb: Drop database if error creating an empty database.
590 >
591 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
592 >    unless selected node not in current dataset.
593 >
594 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
595 >    to TIBCustomService, and IBlocalDB code tidy up.
596 >
597 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
598 >    behaviour due to uninitialised variable.
599 >
600 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
601 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
602 >
603 > 21. IBSQL: When Database changed ensure that all resources are freed.
604 >
605 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
606 >
607 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
608 >    * Line Wrap on SQL Token boundaries (on user command)
609 >    * auto-complete table names in drop down list of table names
610 >    * Double click on tablename or field name adds to SQL text
611 >
612 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
613 >
614 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
615 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
616 >    workaround for a problem in fpc 3.0.4 win64).
617 >
618 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
619 >
620 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
621 >

623 >
624 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
625 >   include remote system name.
626 >
627 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
628 >   tables when data included in output.
629 >
630 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
631 >   and timing information to be written to stdout. This may be used to locate
632 >   performance bottlenecks.
633 >
634 > 4. SQLParser: only call "OnChanging" event handler when value is different.
635 >
636 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
637 >
638 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
639 >   that BindFields is called when the query is next activated. Avoids FieldName
640 >   not found error.
641 >
642 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
643 >   purpose and allows the programmer to define any action they want for Update, Insert
644 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
645 >   filtering of updates, or use of statements such as Grant or Revoke instead of
646 >   normal DML. See User Manual for more information.

651 >
652 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
653 >
654 > 3. TIBExtract: data formatted as Charset set "octets" is now output using

659 >
660 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
661 >   grants to these objects.
662 >
663 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
664 >   dependency problems restoring complex databases.
665 >
666 > 7. TIBXScript: This component has been restructured to allow for the processing of
667 >   embedded XML in INSERT statements and to support interactive sources in addition
668 >   to non-interactive data sources such as files.
669 >
670 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
671 >
672 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
673 >   SET SQL DIALECT
674 >   SET TERM
675 >   SET AUTODDL
676 >   SET BAIL
677 >   SET ECHO
678 >   SET COUNT

680 >   SET NAMES <character set>
681 >
682 > 10. IBVersion unit added to hold current IBX Version Number information.
683 >
684 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
685 >    and domain definitions.
686 >
687 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
688 >    fully supported.
689 >
690 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
691 >
692 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.

695 >
696 > See also doc/IBX4LazarusGuide.pdf for important information on
697 > upgrading to IBX2.
698 >
699 > 1. Size property of TIBStringField is now the width in characters of the field
700 >   and not the byte length. This applies only to multi-byte character sets such
701 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
702 >   code is not recognised as a bug and hence this change to align the behaviour.
703 >   The TStringField change is expected in fpc 3.2.0.
704 >
705 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
706 >   true (default) then Size property value saved in the lfm is ignored. Size is
707 >   always set from the dynamic information read from the database. It is unclear
708 >   why anyone would want to override this and set Size to false.
709 >
710 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
711 >   block.
712 >
713 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
714 >   exist when an attempt is made to connect to it (run time only) then an attempt
715 >   is made to create the database.
716 >
717 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
718 >   has been successfully created as a result of a call to CreateDatabase or when
719 >   creating a database after it was found not to exist.
720 >
721 > 6.  DBControlGrid: a race condition could result in the wrong row image being
722 >    written to the cache. This has been avoided by a trip round the message
723 >    loop before rendering the row image.
724 >
725 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
726 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
727 >    known to risk corrupt rendering of row images when the control is first
728 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
729 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
730 >
731 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
732 >    a TDateEdit control located on an editor panel.
733 >
734 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
735 >
736 > 10. DBControlGrid: Removed memory leak when updating rows.
737 >
738 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

742 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
743 >   when target codepage is CP_NONE. This is a workaround for
744 >   http://bugs.freepascal.org/view.php?id=30622.
745 >
746 > 2. DBLog option removed from TIBStatisticalService - not supported by server
747 >   since Firebird 1.5.
748 >
749 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
750 >   similar.
751 >
752 > 4. IBCodePage: updated mapping between codepages and character id.
753 >
754 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
755 >   Firebird. Character sets with a char width of two are not UTF16.
756 >
757 > 6. Strings received from the database are now always transliterated into UTF8

762 >
763 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
764 >   read in an entire blob just to get the size of the blob. General performance
765 >   improvement when opening datasets containing blobs.
766 >
767 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
768 >
769 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
770 >   is now used.
771 >
772 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
773 >   determined.
774 >
775 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
776 >
777 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post

784 >
785 > 1. No character set specified for connection: when a text blob is retrieved, the
786 >  character set is determined by looking up the native character set using then
787 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
788 >  set as the connection.
789 >
790 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
791 >   for Login Dialog returing a change to the database path.
792 >
793 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
794 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
795 >   entered value to be saved on a project specific basis (design time only).
796 >
797 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
798 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
799 >   Otherwise, it sets the column text to the selected ListField Value.
800 >
801 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
802 >   column width.
803 >
804 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
805 >   and a case insensitive search is requested.
806 >
807 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
808 >   or column ListSource.
809 >
810 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
811 >   unprepare) when closing and the text has not changed.
812 >
813 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
814 >   Less likely to cause a cursor re-use error on Windows.
815 >
816 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
817 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
818 >
819 > 11. TIBTreeView: Guard against nil destination on record changed
820 >

822 >    string type with the code page set to reflect the returned field encoding after
823 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
824 >    earlier versions.
825 >
826 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString

829 >
830 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
831 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
832 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure

956  
957       IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
958       to use the built in dialogs and cursor management. IBDialogs is
959 <     included by default if "ibexpress" is in your project source "uses" clause.
959 >     included by default if "ibexpress" is in your project source's "uses" clause.
960       This should be the case for all projects created through the IDE. This is why
961       you do not want to add the ibexpress package to console mode applications. The
962       ibexpressconsolemode package has been created to allow console mode programs
963       to avoid adding LCL dependencies when using IBX, while still having the
964       unit search paths set up correctly.
965  
966 +     Existing users should check to ensure that the "ibexpress" unit is included in
967 +     each project's source file (*.lpr).
968 +
969       You may find that in order for the IDE to recognise that ibexpressconsolemode
970       exists, you have to first open the package in the IDE and then close it. This
971       adds it to the most recently accessed packages list. To make it permanently
972       available, add the package name to lazarus' staticpackages.inc file.
973  
974 <     Under Windows, the TISQLMonitor OnSQL Event Handler may require a new call to
39 <         Application.ProcessMessages in order to display an event journal correctly. See
40 <         example. This was previously called by TISQLMonitor itself but removed to avoid
