2 >
3 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
4 >    number of UTF8 characters exceeds the string size then string is truncated
5 >    to the maximum string size. This is  usually a problem with fixed width columns
6 >    right padded with white space.
7 >
8 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
9 >    If SQLFiltered is set then when a dataset is opened, each line in the
10 >    SQLFilterParams property is assumed to be a SQL condition clause and
11 >    ANDed into the Where clause of the SQL Select statement provided as a
12 >    dataset property. Each such SQL condition thus acts as an additional filter
13 >    on the dataset. (Not yet tested)
14 >
15 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
16 >    side filters).
17 >
18 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
19 >   text matches complete entry.
20 >
21 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
22 >   dataset are active (avoids risk of access violation if master is inactive)
23 >
24 > 6. TIBEvents: Registered property can now be set at design time even if database not open
25 >
26 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
27 >   This should prevent "spillover" of events between sessions.
28 >
29 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
30 >   This should ensure that the internal buffer is set up correctly and avoids
31 >   a duplicate initial row.
32 >
33 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
34 >   That is, the DataSize should be the field size * character set width. The
35 >   value returned by DataSize is now the same as the Dataset buffer size reserved
36 >   for the field.
37 >
38 > 10. IBExtact: Tidyup of SQL generation. Avoid unnecessary double quotes.
39 >
40 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
41 >    and vice-versa. This may result in an exception being raised (correctly) for
42 >    older programs when using dataset fields added to a form and the database has been
43 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
44 >    In such cases, the field needs to be deleted in the IDE fields editor and then
45 >    added back in.
46 >
47 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
48 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
49 >    is cancelled.
50 >
51 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
52 >
53 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
54 >    not SQL Identifiers are now supported.
55 >
56 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
57 >    passed to the Firebird engine for execution.
58 >
59 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
60 >    is made to scroll back.
61 >
62 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
63 >
64 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
65 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
66 >
67 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
68 >   validated. If no match is found in the list of field names and the database has
69 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
70 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
71 >
72 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
73 >   with fpc 3.2.
74 >
75 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
76 >
77 >
78 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
79 >   and is used to override the default settings in the client side "firebird.conf" This
80 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
81 >   Each line of the string list should be a setting in the same format as "firebird.conf".
82 >   For example "WireCompression = true" in order to request wire compression on the client side.
83 >
84 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
85 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
86 >   also require a compatible setting in the server side "firebird.conf". For example
87 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
88 >   compression to be used.
89 >
90 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
91 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
92 >   ibx/examples/dbinfo for examples of how to display this information.
93 >
94 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
95 >   is a "convenience" property. If set the "WireCompression=true" is added to the
96 >   ConfigOverrides. If unchecked then this setting is removed.
97 >
98 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
99 >   not "INT64".
100 >
101 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
102 >   These are:
103 >    property TimestampFormat: string;
104 >    property DateFormat: string;
105 >    property TimeFormat: string;
106 >
107 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
108 >   DATETIME and TIME. The format strings use the standard FPC date/time format
109 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
110 >
111 >   If any of the above properties are set to an empty string, then the locale default
112 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
113 >   locale default is extended by appending '.zzz' to include milliseconds.
114 >
115 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
116 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
117 >
118 > 5. New published property for TIBCSVDataOut:
119 >     property QuoteStrings: boolean (default true)
120 >
121 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
122 >   used to delimit each and every string in the output.
123 >
124 > 6. New published properties for TIBCSVDataOut:
125 >    property FieldSeparator: string;
126 >    property HeaderSeparator: string;
127 >
128 >   Respectively, these provide the separator character(s) used to separate fields
129 >   in data and header rows. Both default to ','.
130 >
131 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
132 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
133 >    property OnFormatTextString;
134 >
135 >   This event handler can be used to process text strings before they are included
136 >   in the output e.g. to replace unprintable characters with alternative strings.
137 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
138 >
139 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
140 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
141 >   and without raising and exception if it does not.
142 >
143 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
144 >   consistency with SQL queries.
145 >
146 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
147 >    When true, SQL statement parameter names are parsed case sensitive. Note for
148 >    TIBDataSet only applies to Select query.
149 >
150 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
151 >    an IDE exception.
152 >
153 > 12. LocalDBSupport: initial database creation should now work correctly
154 >    when the schema source is an sql file.
155 >
156 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
157 >    when defined, this handler will be called by the internal TIBXScript during
158 >    initial database creation when the schema source is an sql file and may be used
159 >    to provide a visual indication of progress in console mode.
160 >
161 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
162 >    to true while a new local database is being created and its schema populated.
163 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
164 >    when the database is disconnected/connected during the create DB procedure.
165 >
166 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
167 >    are now always ignored and replaced by the user name and password provided as
168 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
169 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
170 >    completely ignored if this property is true.
171 >
172 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
173 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
174 >    ImageIndex and SelectImageIndex values on AddNode.
175 >
176 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
177 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
178 >    the same database connection.
179 >
180 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
181 >    if provided, this should be an conditional SQL expression suitable for
182 >    including in an SQL Select statement "where" clause. If non-empty and the
183 >    "Filtered" property is true then the SQL expression provided as the value of
184 >    the "Filter" property is "ANDed" with any existing condition statement
185 >    in the SQL statement's "Where" clause.
186 >
187 >    If the "Filter" property is set at run time, the "Filtered" property is true
188 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
189 >
190 >    The "Filter" condition may include IBX style parameters. In which case, their
191 >    value must be set by the dataset's "OnBeforeOpen" event handler.
192 >
193 >    This is a public property for TIBDataSet and TIBQuery query and intended for
194 >    use at run time.
195 >
196 >    Note: The property is a published property of TIBTable. The TIBTable functionality
197 >    is unaffected by this change.
198 >
199 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
200 >
201 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
202 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
203 >   mode apps.
204 >
205 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
206 >   statement. This avoids problems if "Execute Block" is used as the Query.
207 >
208 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
209 >   internal SQL tokeniser routines.
210 >
211 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
212 >   as a select statement, with or without CTEs.
213 >
214 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
215 >
216 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
217 >   internal SQL tokeniser routines.
218 >
219 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
220 >    being raised for valid set statements processed by a data formatter.
221 >
222 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
223 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
224 >   the path of the Firebird Library used by the database/services connection.
225 >
226 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
227 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
228 >   services connection.
229 >
230 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
231 >   or param name is not a valid SQL identifier.
232 >
233 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
234 >    view of whether the text box should be editable when no DataSource is specified.
235 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
236 >    ReadOnly is false, the text box is editable when no DataSource is specified.
237 >
238 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
239 >    the FBLIB environment variable. If you do not want to permit this then you
240 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
241 >    this setting.
242 >
243 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
244 >
245 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
246 >   Utf8EscapeControlChars
247 >
248 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
249 >
250 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
251 > all previous copies of the IBX source code tree before installing this release.
252 >
253 > The IBX packages used by most users have not changed, with one exception. The
254 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
255 > to use the IBServices unit in your applications, please add the iblegacyServices
256 > to the list of dependencies. To do this, open the Project Inspector and select
257 > Add->New Requirement and select "ibLegacyServices" from the list of available
258 > packages.
259 >
260 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
261 >   the IBServices unit providing what is intended to be a clearer and easier to
262 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
263 >   more information and the guide to "Firebird Service Management Using IBX".
264 >   As indicated above, the legacy services components are still available and
265 >   provided in a separate package. There is no need to update working applications
266 >   using the older versions except for an additional package dependency.
267 >
268 > 2. The IBX packages and source code tree have been re-organised in an attempt to
269 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
270 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
271 >   new set of IBX packages.
272 >
273 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
274 >   updated to use the new Services API components.
275 >
276 > 4. The iblocal package has been updated to use the new Services API components.
277 >
278 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
279 >   TIBXSecurityService. It had been wrongly classified in the previous version
280 >   as a per database configuration item. It is global to a server and hence
281 >   correctly positioned as part of the Security Package. In the DBAdmin example,
282 >   the setting has moved to the mappings page.
283 >
284 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
285 >   are ignored.
286 >
287 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
288 >   closed before the database is dropped. Before and After Disconnect event handlers
289 >   are also fired.
290 >
291 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
292 >   is started and not just the first time.
293 >
294 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
295 >   depenendency with comp type.
296 >
297 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
298 >
299 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
300 >    then this is recognised and not ignored.
301 >
302 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
303 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
304 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
305 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
306 >
307 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
308 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
309 >    counters for the select query. Note: stats accumulate after each fetch from
310 >    the database. To get total query cost after open, call the "Last" method
311 >    and then GetPerfStatistics.
312 >
313 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
314 >
315 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
316 >    in parenthesises.
317 >
318 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
319 >    SQL identifiers are always delimited by double quotes. If false, then they are
320 >    only delimited if the identifier is a reserved word, contains lower case or special
321 >    characters. Set this property to true to retain previous behaviour.
322 >
323 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
324 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
325 >
326 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
327 >       property MasterDetailDelay: integer {defaults to zero}
328 >
329 >    When non-zero and the dataset is a detail table referencing a master table
330 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
331 >    then a synchronisation delay is added (in milliseconds) between the master
332 >    row changing and the detail dataset being re-opened. If the master dataset
333 >    is scrolled before the delay expires then the delay is reset. This can be used
334 >    to avoid performance overheads when scrolling through a large master dataset.
335 >
336 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
337 >    chreads unit must be included in your project. TTimer is not used in order
338 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
339 >
340 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
341 >    with Extract Option eoDatabase.
342 >
343 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
344 >    When a deLayoutChanged event is reported on the ListSource dataset, the
345 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
346 >    relationship with the control's datasource (master).
347 >
348 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
349 >
350 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
351 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
352 >
353 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
354 >    DDL (Firebird 3 and later only).
355 >
356 > 22. TIBLookupComboBox Autocomplete Fixes:
357 >    i. Only appended text is now selected after autocomplete.
358 >    ii. Uppercase keys no longer ignored for autocomplete.
359 >    iii. Retain Prefix case is now honoured correctly.
360 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
361 >        before autocomplete performed. i.e. behaviour now the same as when
362 >        no DataSource assigned.
363 >
364 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
365 >    between SQL statements.
366 >
367 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
368 >    ObjectNames are converted to upper case before matching against metadata object
369 >    names, unless the objectname is delimited by double quotes, in which case, the
370 >    double quotes are removed and the remaining string is used (unmodified) to match
371 >    against the metadata object name.
372 >
373 >    If true then the ObjectName is used as is without modification and matched
374 >    against the metadata object name. No attempt is made to remove double quotes.
375 >
376 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
377 >    with eoTrigger, these extract types can be used to select only Database Triggers,
378 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
379 >
380 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
381 >    statement separate character is now reset to the default (';').
382 >
383 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
384 >
385 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
386 >    a commit or reconnect statement and instead activated only when next SQL statement
387 >    is executed.
388 >
389 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
390 >
391 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
392 >    converting statement to upper case.
393 >
394 > 31. TIBExtract: metadata comments now supported. New published property
395 >    IncludeMetaDataComments (default true). If true then metadata comments included
396 >    in extracted DDL. New Extract Object member eoComments. This may be used with
397 >    ExtractObject method to list all metadata comments.
398 >
399 > 32. TIBExtract: ListObjectNames method added.
400 >
401 > 33. Updated Database component editor to support additional connection string
402 >    types.
403 >
404 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
405 >
406 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
407 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
408 > RELEASE.
409 >
410 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
411 >
412 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
413 >
414 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
415 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
416 >   information). However, this is also a very useful mechanism for returning updated computed by
417 >   column values. Values returned as a result of executing an Insert or Update statement
418 >   replace existing values in the current row for each corresponding column.
419 >
420 >   Previously, if a dataset's select query included read only (computed by) fields then
421 >   an automatic row refresh was performed after an insert or update query had been processed,
422 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
423 >   that an automatic refresh is no longer performed if an insert or update query contains
424 >   a returning clause that updates one or more fields on the current row. A full row
425 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
426 >   field values and the select query contains read only fields. Use of Insert/update
427 >   returning should be significantly more efficient than executing a refresh query.
428 >
429 >   This behaviour change is intended to be backwards compatible and there should be no need to change
430 >   existing programs, other than to improve performance by using the new capability.
431 >
432 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
433 >   they are called when the dataset row is being deleted, there is no value in
434 >   updating the current record from the query result. Instead, a new event handler
435 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
436 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
437 >   by the query. The event handler can then interrogate the query results and
438 >   perform whatever action is necessary. For example to confirm, to the user,
439 >   the deletion of a row with the returned values.
440 >
441 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
442 >   any Computed By or Identity Columns. The IBTables example has been updated to
443 >   illustrate the computation of the employee Full Name on update.
444 >
445 > 5. TIBTable: The GeneratorField property is now published.
446 >
447 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
448 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
449 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
450 >   each Identity column after the insert is executed.
451 >
452 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
453 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
454 >   Insert..Returning clause.
455 >
456 > 8. TIBGenerator: small performance improvement by not preparing query each time
457 >   a new value is generated.
458 >
459 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
460 >
461 > 10. Property editors will now sync table name to a System Table when "Include System
462 >    Tables" is selected and the query is for a System Table.
463 >
464 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
465 >    values are no longer converted to milliseconds from TDateTime and then back again
466 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
467 >
468 > 12. Property Editors handling of Stored Procedures.
469 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
470 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
471 >      query).
472 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
473 >
474 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
475 >    can be used to select a package. If non-empty, the stored procedure name is
476 >    expected to be a stored procedure defined in the specified package and the
477 >    generated SQL will be as required for a stored procedure located in a package.
478 >
479 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
480 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
481 >    which a stored procedure can be selected. With no package name selected, non-package
482 >    stored procedures are listed.
483 >
484 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
485 >    for password on reconnect.
486 >
487 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
488 >    and character set name.
489 >
490 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
491 >    DB info lookups"
492 >
493 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
494 >
495 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
496 >
497 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
498 >    parameters. This stops an exception being raised when the field cannot be
499 >    located in the record buffer.
500 >
501 > 21. Property Editors now automatically include System Tables when opened and when the query table
502 >    is a System Table.
503 >
504 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
505 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
506 >
507 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
508 >    add the SPB item isc_spb_expected_db. This names a database using
509 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
510 >    database. examples/services re-written to illustrate use of "expected_db".
511 >
512 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
513 >    This avoids truncated backups when the server returns a timeout (busy) response.
514 >
515 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
516 >
517 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
518 >    databasenames. These are respectively expanded to the local system's temp directory
519 >    (including trailing delimiter) or to a prescribed data directory (including
520 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
521 >    in the user's home directory. The hidden directory name is either the string returned
522 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
523 >    Under Windows, the directory is the same as the Data Directory as decribed
524 >    above but instead prefixed by the User's application data path. These may be
525 >    used to improve application portability for Personal Databases.
526 >
527 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
528 >    this has not worked for a long time and is not useful either. FieldDefs should be
529 >    managed using the Fields Editor as with any other dataset. To access the fields
530 >    editor for a TIBTable component, double click on the component. The fields editor
531 >    is then displayed.
532 >
533 > 28. TIBDatabaseInfo: new properties/function
534 >     * DateDBCreated (returns date/time database created)
535 >     * TransactionCount (returns no. of active transactions)
536 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
537 >     * PagesFree (Firebird 3 or later)
538 >     * PagesUsed (Firebird 3 or later)
539 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
540 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
541 >
542 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
543 >
544 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
545 >
546 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
547 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
548 >
549 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
550 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
551 >    firing during backup and restore.
552 >
553 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
554 >    for verbose output using the new property "StatisticsRequested".
555 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
556 >
557 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
558 >
559 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
560 >    palette. This uses the online validation feature added in Firebird 2.5. The
561 >    services's properties enable inclusion/exclusion of tables and indexes using
562 >    regular expressions. See.
563 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
564 >
565 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
566 >    option on a database.
567 >
568 > 37. TIBCustomService: Assign method implemented to allow copying of service login
569 >    context between service API components. "Detach" method now only detaches
570 >    service when last reference to the service interface detaches. Tidy up of
571 >    code for SetActive and Attach methods including password hiding.
572 >
573 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
574 >    and used to determine the auth method and protocol used for the connection.
575 >
576 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
577 >    a Create Database Statement generated by IBX.
578 >
579 > 40. All IBServices now have an additional published property "PortNo". This may
580 >    be set to a non-standard port number when necessary. If zero then the default
581 >    port number is used.
582 >
583 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
584 >    and not just the mouse.
585 >
586 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
587 >
588 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
589 >    image index and selected image index for each node to be set from a database field.
590 >
591 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
592 >    then database schema includes grants to all users. If not present then the
593 >    only user grants included are those to User PUBLIC.
594 >
595 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
596 >    and child nodes in dataset.

599 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
600  
601   1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
602     changes.
# Line 17 | Line 615 | IBX Change Log  version
615   6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
616     entering a new name into the text box.
617  
618 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
619 +   Firebird rather than recomputing it.
620 +
621 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
622 +   screen centre. Previously some were "poDesigned" which may be inappropriate
623 +   for multi monitor desktops.
624 +
625 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
626 +
627 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
628 +    a transaction and always reset the object.
629 +
630 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
631 +
632 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
633 +
634 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
635 +    to a gbak format archive.
636 +
637 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
638 +
639 + 16. IBLocaldb: Drop database if error creating an empty database.
640 +
641 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
642 +    unless selected node not in current dataset.
643 +
644 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
645 +    to TIBCustomService, and IBlocalDB code tidy up.
646 +
647 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
648 +    behaviour due to uninitialised variable.
649 +
650 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
651 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
652 +
653 + 21. IBSQL: When Database changed ensure that all resources are freed.
654 +
655 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
656 +
657 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
658 +    * Line Wrap on SQL Token boundaries (on user command)
659 +    * auto-complete table names in drop down list of table names
660 +    * Double click on tablename or field name adds to SQL text
661 +
662 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
663 +
664 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
665 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
666 +    workaround for a problem in fpc 3.0.4 win64).
667 +
668 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
669 +
670 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
671 +
672   IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
673  
674   1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
# Line 37 | Line 689 | IBX Change Log  version
689     that BindFields is called when the query is next activated. Avoids FieldName
690     not found error.
691  
692 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
693 +   purpose and allows the programmer to define any action they want for Update, Insert
694 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
695 +   filtering of updates, or use of statements such as Grant or Revoke instead of
696 +   normal DML. See User Manual for more information.
697 +
698   IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
699  
700   1. TIBEvents: Fix uninitialised variable that could result in lost events.
