1 + IBX Change Log  version (2.3-3 Build 11493) Fri, 28 Dec 2018 10:04:17 +0000
2 +
3 +
4 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
5 +   and is used to override the default settings in the client side "firebird.conf" This
6 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
7 +   Each line of the string list should be a setting in the same format as "firebird.conf".
8 +   For example "WireCompression = true" in order to request wire compression on the client side.
9 +
10 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
11 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
12 +   also require a compatible setting in the server side "firebird.conf". For example
13 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
14 +   compression to be used.
15 +
16 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
17 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
18 +   ibx/examples/dbinfo for examples of how to display this information.
19 +
20 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
21 +   is a "convenience" property. If set the "WireCompression=true" is added to the
22 +   ConfigOverrides. If unchecked then this setting is removed.
23 +
24 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
25 +   not "INT64".
26 +
27 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
28 +   These are:
29 +    property TimestampFormat: string;
30 +    property DateFormat: string;
31 +    property TimeFormat: string;
32 +
33 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
34 +   DATETIME and TIME. The format strings use the standard FPC date/time format
35 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
36 +
37 +   If any of the above properties are set to an empty string, then the locale default
38 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
39 +   locale default is extended by appending '.zzz' to include milliseconds.
40 +
41 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
42 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
43 +
44 + 5. New published property for TIBCSVDataOut:
45 +     property QuoteStrings: boolean (default true)
46 +
47 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
48 +   used to delimit each and every string in the output.
49 +
50 + 6. New published properties for TIBCSVDataOut:
51 +    property FieldSeparator: string;
52 +    property HeaderSeparator: string;
53 +
54 +   Respectively, these provide the separator character(s) used to separate fields
55 +   in data and header rows. Both default to ','.
56 +
57 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
58 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
59 +    property OnFormatTextString;
60 +
61 +   This event handler can be used to process text strings before they are included
62 +   in the output e.g. to replace unprintable characters with alternative strings.
63 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
64 +
65 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
66 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
67 +   and without raising and exception if it does not.
68 +
69 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
70 +   consistency with SQL queries.
71 +
72 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
73 +    When true, SQL statement parameter names are parsed case sensitive. Note for
74 +    TIBDataSet only applies to Select query.
75 +
76 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
77 +    an IDE exception.
78 +
79 + 12. LocalDBSupport: initial database creation should now work correctly
80 +    when the schema source is an sql file.
81 +
82 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
83 +    when defined, this handler will be called by the internal TIBXScript during
84 +    initial database creation when the schema source is an sql file and may be used
85 +    to provide a visual indication of progress in console mode.
86 +
87 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
88 +    to true while a new local database is being created and its schema populated.
89 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
90 +    when the database is disconnected/connected during the create DB procedure.
91 +
92 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
93 +    are now always ignored and replaced by the user name and password provided as
94 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
95 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
96 +    completely ignored if this property is true.
97 +
98 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
99 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
100 +    ImageIndex and SelectImageIndex values on AddNode.
101 +
102 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
103 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
104 +    the same database connection.
105 +
106 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
107 +    if provided, this should be an conditional SQL expression suitable for
108 +    including in an SQL Select statement "where" clause. If non-empty and the
109 +    "Filtered" property is true then the SQL expression provided as the value of
110 +    the "Filter" property is "ANDed" with any existing condition statement
111 +    in the SQL statement's "Where" clause.
112 +
113 +    If the "Filter" property is set at run time, the "Filtered" property is true
114 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
115 +
116 +    The "Filter" condition may include IBX style parameters. In which case, their
117 +    value must be set by the dataset's "OnBeforeOpen" event handler.
118 +
119 +    This is a public property for TIBDataSet and TIBQuery query and intended for
120 +    use at run time.
121 +
122 +    Note: The property is a published property of TIBTable. The TIBTable functionality
123 +    is unaffected by this change.
124 +
125 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
126 +
127 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
128 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
129 +   mode apps.
130 +
131 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
132 +   statement. This avoids problems if "Execute Block" is used as the Query.
133 +
134 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
135 +   internal SQL tokeniser routines.
136 +
137 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
138 +   as a select statement, with or without CTEs.
139 +
140 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
141 +
142 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
143 +   internal SQL tokeniser routines.
144 +
145 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
146 +    being raised for valid set statements processed by a data formatter.
147 +
148 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
149 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
150 +   the path of the Firebird Library used by the database/services connection.
151 +
152 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
153 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
154 +   services connection.
155 +
156 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
157 +   or param name is not a valid SQL identifier.
158 +
159 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
160 +    view of whether the text box should be editable when no DataSource is specified.
161 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
162 +    ReadOnly is false, the text box is editable when no DataSource is specified.
163 +
164 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
165 +    the FBLIB environment variable. If you do not want to permit this then you
166 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
167 +    this setting.
168 +
169 + IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
170 +
171 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
172 +   Utf8EscapeControlChars
173 +
174 + IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
175 +
176 + IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
177 + all previous copies of the IBX source code tree before installing this release.
178 +
179 + The IBX packages used by most users have not changed, with one exception. The
180 + IBServices unit has been moved to the package iblegacyServices.lpk. To continue
181 + to use the IBServices unit in your applications, please add the iblegacyServices
182 + to the list of dependencies. To do this, open the Project Inspector and select
183 + Add->New Requirement and select "ibLegacyServices" from the list of available
184 + packages.
185 +
186 + 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
187 +   the IBServices unit providing what is intended to be a clearer and easier to
188 +   use set of IB Services components. See Chapter 10 of the IBX User Guide for
189 +   more information and the guide to "Firebird Service Management Using IBX".
190 +   As indicated above, the legacy services components are still available and
191 +   provided in a separate package. There is no need to update working applications
192 +   using the older versions except for an additional package dependency.
193 +
194 + 2. The IBX packages and source code tree have been re-organised in an attempt to
195 +   finally get rid of the "duplicate ppu" warnings. This re-organisation should
196 +   not affect existing users. Section 2.3 of the IBX User Guide describes the
197 +   new set of IBX packages.
198 +
199 + 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
200 +   updated to use the new Services API components.
201 +
202 + 4. The iblocal package has been updated to use the new Services API components.
203 +
204 + 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
205 +   TIBXSecurityService. It had been wrongly classified in the previous version
206 +   as a per database configuration item. It is global to a server and hence
207 +   correctly positioned as part of the Security Package. In the DBAdmin example,
208 +   the setting has moved to the mappings page.
209 +
210 + 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
211 +   are ignored.
212 +
213 + 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
214 +   closed before the database is dropped. Before and After Disconnect event handlers
215 +   are also fired.
216 +
217 + 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
218 +   is started and not just the first time.
219 +
220 + 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
221 +   depenendency with comp type.
222 +
223 + 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
224 +
225 + 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
226 +    then this is recognised and not ignored.
227 +
228 + 12. TIBDataSet, TIBQuery, TIBTable: additions:
229 +    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
230 +    function GetPerfStatistics(var stats: TPerfCounters): boolean;
231 +    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
232 +
233 +    GetRowsAffected returns the affected row counts from the last insert/update/delete
234 +    if EnableStatistics = true then GetPerfStatistics returns the current stats
235 +    counters for the select query. Note: stats accumulate after each fetch from
236 +    the database. To get total query cost after open, call the "Last" method
237 +    and then GetPerfStatistics.
238 +
239 +    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
240 +
241 + 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
242 +    in parenthesises.
243 +
244 + 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
245 +    SQL identifiers are always delimited by double quotes. If false, then they are
246 +    only delimited if the identifier is a reserved word, contains lower case or special
247 +    characters. Set this property to true to retain previous behaviour.
248 +
249 + 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
250 +    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
251 +
252 + 16. TIBDataSet, TIBQuery, TIBTable: addition:
253 +       property MasterDetailDelay: integer {defaults to zero}
254 +
255 +    When non-zero and the dataset is a detail table referencing a master table
256 +    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
257 +    then a synchronisation delay is added (in milliseconds) between the master
258 +    row changing and the detail dataset being re-opened. If the master dataset
259 +    is scrolled before the delay expires then the delay is reset. This can be used
260 +    to avoid performance overheads when scrolling through a large master dataset.
261 +
262 +    Note: uses fptimer and hence requires a thread manager. Under Linux the
263 +    chreads unit must be included in your project. TTimer is not used in order
264 +    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
265 +
266 + 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
267 +    with Extract Option eoDatabase.
268 +
269 + 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
270 +    When a deLayoutChanged event is reported on the ListSource dataset, the
271 +    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
272 +    relationship with the control's datasource (master).
273 +
274 + 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
275 +
276 + 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
277 +    stubs. Pedantic fix really, as procedures output in dependency order anyway.
278 +
279 + 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
280 +    DDL (Firebird 3 and later only).
281 +
282 + 22. TIBLookupComboBox Autocomplete Fixes:
283 +    i. Only appended text is now selected after autocomplete.
284 +    ii. Uppercase keys no longer ignored for autocomplete.
285 +    iii. Retain Prefix case is now honoured correctly.
286 +    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
287 +        before autocomplete performed. i.e. behaviour now the same as when
288 +        no DataSource assigned.
289 +
290 + 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
291 +    between SQL statements.
292 +
293 + 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
294 +    ObjectNames are converted to upper case before matching against metadata object
295 +    names, unless the objectname is delimited by double quotes, in which case, the
296 +    double quotes are removed and the remaining string is used (unmodified) to match
297 +    against the metadata object name.
298 +
299 +    If true then the ObjectName is used as is without modification and matched
300 +    against the metadata object name. No attempt is made to remove double quotes.
301 +
302 + 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
303 +    with eoTrigger, these extract types can be used to select only Database Triggers,
304 +    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
305 +
306 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
307 +    statement separate character is now reset to the default (';').
308 +
309 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
310 +
311 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
312 +    a commit or reconnect statement and instead activated only when next SQL statement
313 +    is executed.
314 +
315 + 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
316 +
317 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
318 +    converting statement to upper case.
319 +
320 + 31. TIBExtract: metadata comments now supported. New published property
321 +    IncludeMetaDataComments (default true). If true then metadata comments included
322 +    in extracted DDL. New Extract Object member eoComments. This may be used with
323 +    ExtractObject method to list all metadata comments.
324 +
325 + 32. TIBExtract: ListObjectNames method added.
326 +
327 + 33. Updated Database component editor to support additional connection string
328 +    types.
329 +
330 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
331 +
332 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
333 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
334 + RELEASE.
335 +
336 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
337 +
338 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
339 +
340 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
341 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
342 +   information). However, this is also a very useful mechanism for returning updated computed by
343 +   column values. Values returned as a result of executing an Insert or Update statement
344 +   replace existing values in the current row for each corresponding column.
345 +
346 +   Previously, if a dataset's select query included read only (computed by) fields then
347 +   an automatic row refresh was performed after an insert or update query had been processed,
348 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
349 +   that an automatic refresh is no longer performed if an insert or update query contains
350 +   a returning clause that updates one or more fields on the current row. A full row
351 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
352 +   field values and the select query contains read only fields. Use of Insert/update
353 +   returning should be significantly more efficient than executing a refresh query.
354 +
355 +   This behaviour change is intended to be backwards compatible and there should be no need to change
356 +   existing programs, other than to improve performance by using the new capability.
357 +
358 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
359 +   they are called when the dataset row is being deleted, there is no value in
360 +   updating the current record from the query result. Instead, a new event handler
361 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
362 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
363 +   by the query. The event handler can then interrogate the query results and
364 +   perform whatever action is necessary. For example to confirm, to the user,
365 +   the deletion of a row with the returned values.
366 +
367 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
368 +   any Computed By or Identity Columns. The IBTables example has been updated to
369 +   illustrate the computation of the employee Full Name on update.
370 +
371 + 5. TIBTable: The GeneratorField property is now published.
372 +
373 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
374 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
375 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
376 +   each Identity column after the insert is executed.
377 +
378 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
379 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
380 +   Insert..Returning clause.
381 +
382 + 8. TIBGenerator: small performance improvement by not preparing query each time
383 +   a new value is generated.
384 +
385 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
386 +
387 + 10. Property editors will now sync table name to a System Table when "Include System
388 +    Tables" is selected and the query is for a System Table.
389 +
390 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
391 +    values are no longer converted to milliseconds from TDateTime and then back again
392 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
393 +
394 + 12. Property Editors handling of Stored Procedures.
395 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
396 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
397 +      query).
398 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
399 +
400 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
401 +    can be used to select a package. If non-empty, the stored procedure name is
402 +    expected to be a stored procedure defined in the specified package and the
403 +    generated SQL will be as required for a stored procedure located in a package.
404 +
405 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
406 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
407 +    which a stored procedure can be selected. With no package name selected, non-package
408 +    stored procedures are listed.
409 +
410 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
411 +    for password on reconnect.
412 +
413 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
414 +    and character set name.
415 +
416 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
417 +    DB info lookups"
418 +
419 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
420 +
421 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
422 +
423 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
424 +    parameters. This stops an exception being raised when the field cannot be
425 +    located in the record buffer.
426 +
427 + 21. Property Editors now automatically include System Tables when opened and when the query table
428 +    is a System Table.
429 +
430 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
431 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
432 +
433 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
434 +    add the SPB item isc_spb_expected_db. This names a database using
435 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
436 +    database. examples/services re-written to illustrate use of "expected_db".
437 +
438 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
439 +    This avoids truncated backups when the server returns a timeout (busy) response.
440 +
441 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
442 +
443 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
444 +    databasenames. These are respectively expanded to the local system's temp directory
445 +    (including trailing delimiter) or to a prescribed data directory (including
446 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
447 +    in the user's home directory. The hidden directory name is either the string returned
448 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
449 +    Under Windows, the directory is the same as the Data Directory as decribed
450 +    above but instead prefixed by the User's application data path. These may be
451 +    used to improve application portability for Personal Databases.
452 +
453 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
454 +    this has not worked for a long time and is not useful either. FieldDefs should be
455 +    managed using the Fields Editor as with any other dataset. To access the fields
456 +    editor for a TIBTable component, double click on the component. The fields editor
457 +    is then displayed.
458 +
459 + 28. TIBDatabaseInfo: new properties/function
460 +     * DateDBCreated (returns date/time database created)
461 +     * TransactionCount (returns no. of active transactions)
462 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
463 +     * PagesFree (Firebird 3 or later)
464 +     * PagesUsed (Firebird 3 or later)
465 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
466 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
467 +
468 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
469 +
470 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
471 +
472 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
473 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
474 +
475 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
476 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
477 +    firing during backup and restore.
478 +
479 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
480 +    for verbose output using the new property "StatisticsRequested".
481 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
482 +
483 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
484 +
485 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
486 +    palette. This uses the online validation feature added in Firebird 2.5. The
487 +    services's properties enable inclusion/exclusion of tables and indexes using
488 +    regular expressions. See.
489 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
490 +
491 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
492 +    option on a database.
493 +
494 + 37. TIBCustomService: Assign method implemented to allow copying of service login
495 +    context between service API components. "Detach" method now only detaches
496 +    service when last reference to the service interface detaches. Tidy up of
497 +    code for SetActive and Attach methods including password hiding.
498 +
499 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
500 +    and used to determine the auth method and protocol used for the connection.
501 +
502 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
503 +    a Create Database Statement generated by IBX.
504 +
505 + 40. All IBServices now have an additional published property "PortNo". This may
506 +    be set to a non-standard port number when necessary. If zero then the default
507 +    port number is used.
508 +
509 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
510 +    and not just the mouse.
511 +
512 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
513 +
514 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
515 +    image index and selected image index for each node to be set from a database field.
516 +
517 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
518 +    then database schema includes grants to all users. If not present then the
519 +    only user grants included are those to User PUBLIC.
520 +
521 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
522 +    and child nodes in dataset.
523 +
524 +
525 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
526 +
527 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
528 +   changes.
529 +
530 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
531 +   Bug could result in truncated multi-byte character set values.
532 +
533 + 3. Changes consequential on moving fbintf character set utility functions from
534 +   IFirebirdAPI to IAttachment.
535 +
536 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
537 +
538 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
539 +   results in autocomplete ignoring prefix text.
540 +
541 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
542 +   entering a new name into the text box.
543 +
544 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
545 +   Firebird rather than recomputing it.
546 +
547 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
548 +   screen centre. Previously some were "poDesigned" which may be inappropriate
549 +   for multi monitor desktops.
550 +
551 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
552 +
553 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
554 +    a transaction and always reset the object.
555 +
556 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
557 +
558 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
559 +
560 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
561 +    to a gbak format archive.
562 +
563 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
564 +
565 + 16. IBLocaldb: Drop database if error creating an empty database.
566 +
567 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
568 +    unless selected node not in current dataset.
569 +
570 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
571 +    to TIBCustomService, and IBlocalDB code tidy up.
572 +
573 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
574 +    behaviour due to uninitialised variable.
575 +
576 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
577 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
578 +
579 + 21. IBSQL: When Database changed ensure that all resources are freed.
580 +
581 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
582 +
583 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
584 +    * Line Wrap on SQL Token boundaries (on user command)
585 +    * auto-complete table names in drop down list of table names
586 +    * Double click on tablename or field name adds to SQL text
587 +
588 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
589 +
590 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
591 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
592 +    workaround for a problem in fpc 3.0.4 win64).
593 +
594 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
595 +
596 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
597 +
598 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
599 +
600 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
601 +   include remote system name.
602 +
603 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
604 +   tables when data included in output.
605 +
606 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
607 +   and timing information to be written to stdout. This may be used to locate
608 +   performance bottlenecks.
609 +
610 + 4. SQLParser: only call "OnChanging" event handler when value is different.
611 +
612 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
613 +
614 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
615 +   that BindFields is called when the query is next activated. Avoids FieldName
616 +   not found error.
617 +
618 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
619 +   purpose and allows the programmer to define any action they want for Update, Insert
620 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
621 +   filtering of updates, or use of statements such as Grant or Revoke instead of
622 +   normal DML. See User Manual for more information.
623 +
624 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
625 +
626 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
627 +
628 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
629 +
630 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
631 +   hexadecimal notation.
632 +
633 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
634 +   using a simple XML format.
635 +
636 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
637 +   grants to these objects.
638 +
639 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
640 +   dependency problems restoring complex databases.
641 +
642 + 7. TIBXScript: This component has been restructured to allow for the processing of
643 +   embedded XML in INSERT statements and to support interactive sources in addition
644 +   to non-interactive data sources such as files.
645 +
646 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
647 +
648 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
649 +   SET SQL DIALECT
650 +   SET TERM
651 +   SET AUTODDL
652 +   SET BAIL
653 +   SET ECHO
654 +   SET COUNT
655 +   SET STATS
656 +   SET NAMES <character set>
657 +
658 + 10. IBVersion unit added to hold current IBX Version Number information.
659 +
660 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
661 +    and domain definitions.
662 +
663 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
664 +    fully supported.
665 +
666 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
667 +
668 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
669 +
670 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
671 +
672 + See also doc/IBX4LazarusGuide.pdf for important information on
673 + upgrading to IBX2.
674 +
675 + 1. Size property of TIBStringField is now the width in characters of the field
676 +   and not the byte length. This applies only to multi-byte character sets such
677 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
678 +   code is not recognised as a bug and hence this change to align the behaviour.
679 +   The TStringField change is expected in fpc 3.2.0.
680 +
681 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
682 +   true (default) then Size property value saved in the lfm is ignored. Size is
683 +   always set from the dynamic information read from the database. It is unclear
684 +   why anyone would want to override this and set Size to false.
685 +
686 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
687 +   block.
688 +
689 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
690 +   exist when an attempt is made to connect to it (run time only) then an attempt
691 +   is made to create the database.
692 +
693 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
694 +   has been successfully created as a result of a call to CreateDatabase or when
695 +   creating a database after it was found not to exist.
696 +
697 + 6.  DBControlGrid: a race condition could result in the wrong row image being
698 +    written to the cache. This has been avoided by a trip round the message
699 +    loop before rendering the row image.
700 +
701 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
702 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
703 +    known to risk corrupt rendering of row images when the control is first
704 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
705 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
706 +
707 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
708 +    a TDateEdit control located on an editor panel.
709 +
710 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
711 +
712 + 10. DBControlGrid: Removed memory leak when updating rows.
713 +
714 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
715 +
716 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
717 +
718 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
719 +   when target codepage is CP_NONE. This is a workaround for
720 +   http://bugs.freepascal.org/view.php?id=30622.
721 +
722 + 2. DBLog option removed from TIBStatisticalService - not supported by server
723 +   since Firebird 1.5.
724 +
725 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
726 +   similar.
727 +
728 + 4. IBCodePage: updated mapping between codepages and character id.
729 +
730 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
731 +   Firebird. Character sets with a char width of two are not UTF16.
732 +
733 + 6. Strings received from the database are now always transliterated into UTF8
734 +   regardless of the database character set or connection character set. This
735 +   is for compatibility with the LCL.
736 +
737 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
738 +
739 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
740 +   read in an entire blob just to get the size of the blob. General performance
741 +   improvement when opening datasets containing blobs.
742 +
743 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
744 +
745 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
746 +   is now used.
747 +
748 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
749 +   determined.
750 +
751 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
752 +
753 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
754 +   lazarus 1.6.0
755 +
756 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
757 +   compilation error.
758 +
759 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
760 +
761 + 1. No character set specified for connection: when a text blob is retrieved, the
762 +  character set is determined by looking up the native character set using then
763 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
764 +  set as the connection.
765 +
766 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
767 +   for Login Dialog returing a change to the database path.
768 +
769 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
770 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
771 +   entered value to be saved on a project specific basis (design time only).
772 +
773 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
774 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
775 +   Otherwise, it sets the column text to the selected ListField Value.
776 +
777 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
778 +   column width.
779 +
780 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
781 +   and a case insensitive search is requested.
782 +
783 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
784 +   or column ListSource.
785 +
786 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
787 +   unprepare) when closing and the text has not changed.
788 +
789 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
790 +   Less likely to cause a cursor re-use error on Windows.
791 +
792 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
793 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
794 +
795 + 11. TIBTreeView: Guard against nil destination on record changed
796 +
797 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
798 +    string type with the code page set to reflect the returned field encoding after
799 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
800 +    earlier versions.
801 +
802 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
803 +    will now result in transliteration to the code page specified for the Firebird driver
804 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
805 +
806 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
807 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
808 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
809 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
810 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
811 +    the GETACP is used to determine the Windows code page.
812 +
813 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
814 +    name used as the lc_ctype when the database was opened. Only valid while the
815 +    Database is connected.
816 +
817 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
818 +    id that corresponds to the DefaultCharSetName.
