# Line 1 | Line 1
1 + IBX Change Log  version (2.3-5 Build 12341) Mon, 24 Aug 2020 10:23:35 +0100
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.
597 +
598 +
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.
603 +
604 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
605 +   Bug could result in truncated multi-byte character set values.
606 +
607 + 3. Changes consequential on moving fbintf character set utility functions from
608 +   IFirebirdAPI to IAttachment.
609 +
610 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
611 +
612 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
613 +   results in autocomplete ignoring prefix text.
614 +
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
675 +   include remote system name.
676 +
677 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
678 +   tables when data included in output.
679 +
680 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
681 +   and timing information to be written to stdout. This may be used to locate
682 +   performance bottlenecks.
683 +
684 + 4. SQLParser: only call "OnChanging" event handler when value is different.
685 +
686 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
687 +
688 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
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.
701 +
702 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
703 +
704 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
705 +   hexadecimal notation.
706 +
707 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
708 +   using a simple XML format.
709 +
710 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
711 +   grants to these objects.
712 +
713 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
714 +   dependency problems restoring complex databases.
715 +
716 + 7. TIBXScript: This component has been restructured to allow for the processing of
717 +   embedded XML in INSERT statements and to support interactive sources in addition
718 +   to non-interactive data sources such as files.
719 +
720 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
721 +
722 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
723 +   SET SQL DIALECT
724 +   SET TERM
725 +   SET AUTODDL
726 +   SET BAIL
727 +   SET ECHO
728 +   SET COUNT
729 +   SET STATS
730 +   SET NAMES <character set>
731 +
732 + 10. IBVersion unit added to hold current IBX Version Number information.
733 +
734 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
735 +    and domain definitions.
736 +
737 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
738 +    fully supported.
739 +
740 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
741 +
742 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
743 +
744 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
745 +
746 + See also doc/IBX4LazarusGuide.pdf for important information on
747 + upgrading to IBX2.
748 +
749 + 1. Size property of TIBStringField is now the width in characters of the field
750 +   and not the byte length. This applies only to multi-byte character sets such
751 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
752 +   code is not recognised as a bug and hence this change to align the behaviour.
753 +   The TStringField change is expected in fpc 3.2.0.
754 +
755 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
756 +   true (default) then Size property value saved in the lfm is ignored. Size is
757 +   always set from the dynamic information read from the database. It is unclear
758 +   why anyone would want to override this and set Size to false.
759 +
760 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
761 +   block.
762 +
763 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
764 +   exist when an attempt is made to connect to it (run time only) then an attempt
765 +   is made to create the database.
766 +
767 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
768 +   has been successfully created as a result of a call to CreateDatabase or when
769 +   creating a database after it was found not to exist.
770 +
771 + 6.  DBControlGrid: a race condition could result in the wrong row image being
772 +    written to the cache. This has been avoided by a trip round the message
773 +    loop before rendering the row image.
774 +
775 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
776 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
777 +    known to risk corrupt rendering of row images when the control is first
778 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
779 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
780 +
781 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
782 +    a TDateEdit control located on an editor panel.
783 +
784 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
785 +
786 + 10. DBControlGrid: Removed memory leak when updating rows.
787 +
788 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
