1 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
2 +
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.
24 +
25 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
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
421 +      query).
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
427 +    generated SQL will be as required for a stored procedure located in a package.
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
432 +    stored procedures are listed.
433 +
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
449 +    located in the record buffer.
450 +
451 + 21. Property Editors now automatically include System Tables when opened and when the query table
452 +    is a System Table.
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".
505 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
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.
513 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
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.
547 +
548 +
549 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
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 +
622 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
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.
