1 + IBX Change Log  version (2.3-3 Build 11336) Fri, 28 Dec 2018 10:04:17 +0000
2 +
3 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
4 +   and is used to override the default settings in the client side "firebird.conf" This
5 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
6 +   Each line of the string list should be a setting in the same format as "firebird.conf".
7 +   For example "WireCompression = true" in order to request wire compression on the client side.
8 +
9 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
10 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
11 +   also require a compatible setting in the server side "firebird.conf". For example
12 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
13 +   compression to be used.
14 +
15 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
16 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
17 +   ibx/examples/dbinfo for examples of how to display this information.
18 +
19 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
20 +   is a "convenience" property. If set the "WireCompression=true" is added to the
21 +   ConfigOverrides. If unchecked then this setting is removed.
22 +
23 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
24 +   not "INT64".
25 +
26 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
27 +   These are:
28 +    property TimestampFormat: string;
29 +    property DateFormat: string;
30 +    property TimeFormat: string;
31 +
32 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
33 +   DATETIME and TIME. The format strings use the standard FPC date/time format
34 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
35 +
36 +   If any of the above properties are set to an empty string, then the locale default
37 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
38 +   locale default is extended by appending '.zzz' to include milliseconds.
39 +
40 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
41 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
42 +
43 + 5. New published property for TIBCSVDataOut:
44 +     property QuoteStrings: boolean (default true)
45 +
46 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
47 +   used to delimit each and every string in the output.
48 +
49 + 6. New published properties for TIBCSVDataOut:
50 +    property FieldSeparator: string;
51 +    property HeaderSeparator: string;
52 +
53 +   Respectively, these provide the separator character(s) used to separate fields
54 +   in data and header rows. Both default to ','.
55 +
56 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
57 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
58 +    property OnFormatTextString;
59 +
60 +   This event handler can be used to process text strings before they are included
61 +   in the output e.g. to replace unprintable characters with alternative strings.
62 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
63 +
64 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
65 +
66 + 9. TIBQuery now uses IBX SQL Parser instead of TParams SQL parser in order to ensure
67 +   consistency with SQL queries.
68 +
69 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
70 +    When true, SQL statement parameter names are parsed case sensitive. Note for
71 +    TIBDataSet only applies to Select query.
72 +
73 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
74 +
75 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
76 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
77 +   mode apps.
78 +
79 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
80 +   statement. This avoids problems if "Execute Block" is used as the Query.
81 +
82 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
83 +   internal SQL tokeniser routines.
84 +
85 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
86 +   as a select statement, with or without CTEs.
87 +
88 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
89 +
90 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
91 +   internal SQL tokeniser routines.
92 +
93 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
94 +    being raised for valid set statements processed by a data formatter.
95 +
96 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
97 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
98 +   the path of the Firebird Library used by the database/services connection.
99 +
100 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
101 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
102 +   services connection.
103 +
104 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
105 +   or param name is not a valid SQL identifier.
106 +
107 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
108 +    view of whether the text box should be editable when no DataSource is specified.
109 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
110 +    ReadOnly is false, the text box is editable when no DataSource is specified.
111 +
112 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
113 +    the FBLIB environment variable. If you do not want to permit this then you
114 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
115 +    this setting.
116 +
117 + IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
118 +
119 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
120 +   Utf8EscapeControlChars
121 +
122 + IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
123 +
124 + IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
125 + all previous copies of the IBX source code tree before installing this release.
126 +
127 + The IBX packages used by most users have not changed, with one exception. The
128 + IBServices unit has been moved to the package iblegacyServices.lpk. To continue
129 + to use the IBServices unit in your applications, please add the iblegacyServices
130 + to the list of dependencies. To do this, open the Project Inspector and select
131 + Add->New Requirement and select "ibLegacyServices" from the list of available
132 + packages.
133 +
134 + 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
135 +   the IBServices unit providing what is intended to be a clearer and easier to
136 +   use set of IB Services components. See Chapter 10 of the IBX User Guide for
137 +   more information and the guide to "Firebird Service Management Using IBX".
138 +   As indicated above, the legacy services components are still available and
139 +   provided in a separate package. There is no need to update working applications
140 +   using the older versions except for an additional package dependency.
141 +
142 + 2. The IBX packages and source code tree have been re-organised in an attempt to
143 +   finally get rid of the "duplicate ppu" warnings. This re-organisation should
144 +   not affect existing users. Section 2.3 of the IBX User Guide describes the
145 +   new set of IBX packages.
146 +
147 + 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
148 +   updated to use the new Services API components.
149 +
150 + 4. The iblocal package has been updated to use the new Services API components.
151 +
152 + 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
153 +   TIBXSecurityService. It had been wrongly classified in the previous version
154 +   as a per database configuration item. It is global to a server and hence
155 +   correctly positioned as part of the Security Package. In the DBAdmin example,
156 +   the setting has moved to the mappings page.
157 +
158 + 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
159 +   are ignored.
160 +
161 + 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
162 +   closed before the database is dropped. Before and After Disconnect event handlers
163 +   are also fired.
164 +
165 + 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
166 +   is started and not just the first time.
167 +
168 + 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
169 +   depenendency with comp type.
170 +
171 + 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
172 +
173 + 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
174 +    then this is recognised and not ignored.
175 +
176 + 12. TIBDataSet, TIBQuery, TIBTable: additions:
177 +    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
178 +    function GetPerfStatistics(var stats: TPerfCounters): boolean;
179 +    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
180 +
181 +    GetRowsAffected returns the affected row counts from the last insert/update/delete
182 +    if EnableStatistics = true then GetPerfStatistics returns the current stats
183 +    counters for the select query. Note: stats accumulate after each fetch from
184 +    the database. To get total query cost after open, call the "Last" method
185 +    and then GetPerfStatistics.
186 +
187 +    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
188 +
189 + 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
190 +    in parenthesises.
191 +
192 + 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
193 +    SQL identifiers are always delimited by double quotes. If false, then they are
194 +    only delimited if the identifier is a reserved word, contains lower case or special
195 +    characters. Set this property to true to retain previous behaviour.
196 +
197 + 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
198 +    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
199 +
200 + 16. TIBDataSet, TIBQuery, TIBTable: addition:
201 +       property MasterDetailDelay: integer {defaults to zero}
202 +
203 +    When non-zero and the dataset is a detail table referencing a master table
204 +    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
205 +    then a synchronisation delay is added (in milliseconds) between the master
206 +    row changing and the detail dataset being re-opened. If the master dataset
207 +    is scrolled before the delay expires then the delay is reset. This can be used
208 +    to avoid performance overheads when scrolling through a large master dataset.
209 +
210 +    Note: uses fptimer and hence requires a thread manager. Under Linux the
211 +    chreads unit must be included in your project. TTimer is not used in order
212 +    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
213 +
214 + 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
215 +    with Extract Option eoDatabase.
216 +
217 + 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
218 +    When a deLayoutChanged event is reported on the ListSource dataset, the
219 +    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
220 +    relationship with the control's datasource (master).
221 +
222 + 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
223 +
224 + 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
225 +    stubs. Pedantic fix really, as procedures output in dependency order anyway.
226 +
227 + 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
228 +    DDL (Firebird 3 and later only).
229 +
230 + 22. TIBLookupComboBox Autocomplete Fixes:
231 +    i. Only appended text is now selected after autocomplete.
232 +    ii. Uppercase keys no longer ignored for autocomplete.
233 +    iii. Retain Prefix case is now honoured correctly.
234 +    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
235 +        before autocomplete performed. i.e. behaviour now the same as when
236 +        no DataSource assigned.
237 +
238 + 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
239 +    between SQL statements.
240 +
241 + 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
242 +    ObjectNames are converted to upper case before matching against metadata object
243 +    names, unless the objectname is delimited by double quotes, in which case, the
244 +    double quotes are removed and the remaining string is used (unmodified) to match
245 +    against the metadata object name.
246 +
247 +    If true then the ObjectName is used as is without modification and matched
248 +    against the metadata object name. No attempt is made to remove double quotes.
249 +
250 + 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
251 +    with eoTrigger, these extract types can be used to select only Database Triggers,
252 +    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
253 +
254 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
255 +    statement separate character is now reset to the default (';').
256 +
257 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
258 +
259 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
260 +    a commit or reconnect statement and instead activated only when next SQL statement
261 +    is executed.
262 +
263 + 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
264 +
265 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
266 +    converting statement to upper case.
267 +
268 + 31. TIBExtract: metadata comments now supported. New published property
269 +    IncludeMetaDataComments (default true). If true then metadata comments included
270 +    in extracted DDL. New Extract Object member eoComments. This may be used with
271 +    ExtractObject method to list all metadata comments.
272 +
273 + 32. TIBExtract: ListObjectNames method added.
274 +
275 + 33. Updated Database component editor to support additional connection string
276 +    types.
277 +
278 + IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
279 +
280 + NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
281 + AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
282 + RELEASE.
283 +
284 + NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
285 +
286 + 1. IBExtract: Identity columns - add additional check for null column for generator name.
287 +
288 + 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
289 +   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
290 +   information). However, this is also a very useful mechanism for returning updated computed by
291 +   column values. Values returned as a result of executing an Insert or Update statement
292 +   replace existing values in the current row for each corresponding column.
293 +
294 +   Previously, if a dataset's select query included read only (computed by) fields then
295 +   an automatic row refresh was performed after an insert or update query had been processed,
296 +   irrespective of the setting of the "ForcedUpdates" property. This has changed such
297 +   that an automatic refresh is no longer performed if an insert or update query contains
298 +   a returning clause that updates one or more fields on the current row. A full row
299 +   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
300 +   field values and the select query contains read only fields. Use of Insert/update
301 +   returning should be significantly more efficient than executing a refresh query.
302 +
303 +   This behaviour change is intended to be backwards compatible and there should be no need to change
304 +   existing programs, other than to improve performance by using the new capability.
305 +
306 + 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
307 +   they are called when the dataset row is being deleted, there is no value in
308 +   updating the current record from the query result. Instead, a new event handler
309 +   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
310 +   an OnDeleteReturning event handler is provided then it is called with the IResults returned
311 +   by the query. The event handler can then interrogate the query results and
312 +   perform whatever action is necessary. For example to confirm, to the user,
313 +   the deletion of a row with the returned values.
314 +
315 + 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
316 +   any Computed By or Identity Columns. The IBTables example has been updated to
317 +   illustrate the computation of the employee Full Name on update.
318 +
319 + 5. TIBTable: The GeneratorField property is now published.
320 +
321 + 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
322 +   When InsertSQL is generated, the Identity columns are not included in the list of values to
323 +   be inserted. A RETURNING clause is added to the insert statement to return the value of
324 +   each Identity column after the insert is executed.
325 +
326 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
327 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
328 +   Insert..Returning clause.
329 +
330 + 8. TIBGenerator: small performance improvement by not preparing query each time
331 +   a new value is generated.
332 +
333 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
334 +
335 + 10. Property editors will now sync table name to a System Table when "Include System
336 +    Tables" is selected and the query is for a System Table.
337 +
338 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
339 +    values are no longer converted to milliseconds from TDateTime and then back again
340 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
341 +
342 + 12. Property Editors handling of Stored Procedures.
343 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
344 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
345 +      query).
346 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
347 +
348 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
349 +    can be used to select a package. If non-empty, the stored procedure name is
350 +    expected to be a stored procedure defined in the specified package and the
351 +    generated SQL will be as required for a stored procedure located in a package.
352 +
353 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
354 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
355 +    which a stored procedure can be selected. With no package name selected, non-package
356 +    stored procedures are listed.
357 +
358 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
359 +    for password on reconnect.
360 +
361 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
362 +    and character set name.
363 +
364 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
365 +    DB info lookups"
366 +
367 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
368 +
369 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
370 +
371 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
372 +    parameters. This stops an exception being raised when the field cannot be
373 +    located in the record buffer.
374 +
375 + 21. Property Editors now automatically include System Tables when opened and when the query table
376 +    is a System Table.
377 +
378 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
379 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
380 +
381 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
382 +    add the SPB item isc_spb_expected_db. This names a database using
383 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
384 +    database. examples/services re-written to illustrate use of "expected_db".
385 +
386 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
387 +    This avoids truncated backups when the server returns a timeout (busy) response.
388 +
389 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
390 +
391 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
392 +    databasenames. These are respectively expanded to the local system's temp directory
393 +    (including trailing delimiter) or to a prescribed data directory (including
394 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
395 +    in the user's home directory. The hidden directory name is either the string returned
396 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
397 +    Under Windows, the directory is the same as the Data Directory as decribed
398 +    above but instead prefixed by the User's application data path. These may be
399 +    used to improve application portability for Personal Databases.
400 +
401 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
402 +    this has not worked for a long time and is not useful either. FieldDefs should be
403 +    managed using the Fields Editor as with any other dataset. To access the fields
404 +    editor for a TIBTable component, double click on the component. The fields editor
405 +    is then displayed.
406 +
407 + 28. TIBDatabaseInfo: new properties/function
408 +     * DateDBCreated (returns date/time database created)
409 +     * TransactionCount (returns no. of active transactions)
410 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
411 +     * PagesFree (Firebird 3 or later)
412 +     * PagesUsed (Firebird 3 or later)
413 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
414 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
415 +
416 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
417 +
418 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
419 +
420 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
421 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
422 +
423 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
424 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
425 +    firing during backup and restore.
426 +
427 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
428 +    for verbose output using the new property "StatisticsRequested".
429 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
430 +
431 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
432 +
433 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
434 +    palette. This uses the online validation feature added in Firebird 2.5. The
435 +    services's properties enable inclusion/exclusion of tables and indexes using
436 +    regular expressions. See.
437 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
438 +
439 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
440 +    option on a database.
441 +
442 + 37. TIBCustomService: Assign method implemented to allow copying of service login
443 +    context between service API components. "Detach" method now only detaches
444 +    service when last reference to the service interface detaches. Tidy up of
445 +    code for SetActive and Attach methods including password hiding.
446 +
447 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
448 +    and used to determine the auth method and protocol used for the connection.
449 +
450 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
451 +    a Create Database Statement generated by IBX.
452 +
453 + 40. All IBServices now have an additional published property "PortNo". This may
454 +    be set to a non-standard port number when necessary. If zero then the default
455 +    port number is used.
456 +
457 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
458 +    and not just the mouse.
459 +
460 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
461 +
462 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
463 +    image index and selected image index for each node to be set from a database field.
464 +
465 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
466 +    then database schema includes grants to all users. If not present then the
467 +    only user grants included are those to User PUBLIC.
468 +
469 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
470 +    and child nodes in dataset.
471 +

473 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
474 +
475 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
476 +   changes.
477 +
478 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
479 +   Bug could result in truncated multi-byte character set values.
480 +
481 + 3. Changes consequential on moving fbintf character set utility functions from
482 +   IFirebirdAPI to IAttachment.
483 +
484 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
485 +
486 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
487 +   results in autocomplete ignoring prefix text.
488 +
489 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
490 +   entering a new name into the text box.
491 +
492 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
493 +   Firebird rather than recomputing it.
494 +
495 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
496 +   screen centre. Previously some were "poDesigned" which may be inappropriate
497 +   for multi monitor desktops.
498 +
499 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
500 +
501 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
502 +    a transaction and always reset the object.
503 +
504 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
505 +
506 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
507 +
508 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
509 +    to a gbak format archive.
510 +
511 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
512 +
513 + 16. IBLocaldb: Drop database if error creating an empty database.
514 +
515 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
516 +    unless selected node not in current dataset.
517 +
518 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
519 +    to TIBCustomService, and IBlocalDB code tidy up.
520 +
521 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
522 +    behaviour due to uninitialised variable.
523 +
524 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
525 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
526 +
527 + 21. IBSQL: When Database changed ensure that all resources are freed.
528 +
529 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
530 +
531 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
532 +    * Line Wrap on SQL Token boundaries (on user command)
533 +    * auto-complete table names in drop down list of table names
534 +    * Double click on tablename or field name adds to SQL text
535 +
536 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
537 +
538 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
539 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
540 +    workaround for a problem in fpc 3.0.4 win64).
541 +
542 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
543 +
544 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
545 +
546 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
547 +
548 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
549 +   include remote system name.
550 +
551 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
552 +   tables when data included in output.
553 +
554 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
555 +   and timing information to be written to stdout. This may be used to locate
556 +   performance bottlenecks.
557 +
558 + 4. SQLParser: only call "OnChanging" event handler when value is different.
559 +
560 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
561 +
562 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
563 +   that BindFields is called when the query is next activated. Avoids FieldName
564 +   not found error.
565 +
566 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
567 +   purpose and allows the programmer to define any action they want for Update, Insert
568 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
569 +   filtering of updates, or use of statements such as Grant or Revoke instead of
570 +   normal DML. See User Manual for more information.
571 +
572 + IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
573 +
574 + 1. TIBEvents: Fix uninitialised variable that could result in lost events.
575 +
576 + 2. TIBExtract: Added support for FB3 "USAGE" privilege.
577 +
578 + 3. TIBExtract: data formatted as Charset set "octets" is now output using
579 +   hexadecimal notation.
580 +
581 + 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
582 +   using a simple XML format.
583 +
584 + 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
585 +   grants to these objects.
586 +
587 + 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
588 +   dependency problems restoring complex databases.
589 +
590 + 7. TIBXScript: This component has been restructured to allow for the processing of
591 +   embedded XML in INSERT statements and to support interactive sources in addition
592 +   to non-interactive data sources such as files.
593 +
594 + 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
595 +
596 + 9. TIBXScript: ISQL compatiable Set statements are now supported:
597 +   SET SQL DIALECT
598 +   SET TERM
599 +   SET AUTODDL
600 +   SET BAIL
601 +   SET ECHO
602 +   SET COUNT
603 +   SET STATS
604 +   SET NAMES <character set>
605 +
606 + 10. IBVersion unit added to hold current IBX Version Number information.
607 +
608 + 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
609 +    and domain definitions.
610 +
611 + 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
612 +    fully supported.
613 +
614 + 13. TIBExtract: when a database dump includes data, the generator values are now also set.
615 +
616 + 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
617 +

619 +
620 + See also doc/IBX4LazarusGuide.pdf for important information on
621 + upgrading to IBX2.
622 +
623 + 1. Size property of TIBStringField is now the width in characters of the field
624 +   and not the byte length. This applies only to multi-byte character sets such
625 +   as UTF8. The original approach aligned with TStringField. However, the TStringField
626 +   code is not recognised as a bug and hence this change to align the behaviour.
627 +   The TStringField change is expected in fpc 3.2.0.
628 +
629 + 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
630 +   true (default) then Size property value saved in the lfm is ignored. Size is
631 +   always set from the dynamic information read from the database. It is unclear
632 +   why anyone would want to override this and set Size to false.
633 +
634 + 3. ibxscript: should now handle correctly a Case..End statement within a procedure
635 +   block.
636 +
637 + 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
638 +   exist when an attempt is made to connect to it (run time only) then an attempt
639 +   is made to create the database.
640 +
641 + 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
642 +   has been successfully created as a result of a call to CreateDatabase or when
643 +   creating a database after it was found not to exist.
644 +
645 + 6.  DBControlGrid: a race condition could result in the wrong row image being
646 +    written to the cache. This has been avoided by a trip round the message
647 +    loop before rendering the row image.
648 +
649 + 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
650 +    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
651 +    known to risk corrupt rendering of row images when the control is first
652 +    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
653 +    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
654 +
655 + 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
656 +    a TDateEdit control located on an editor panel.
657 +
658 + 9.  TIBExtract: brought up-to-date plus many bug fixes.
659 +
660 + 10. DBControlGrid: Removed memory leak when updating rows.
661 +
662 + 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
663 +
664 + IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
665 +
666 + 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
667 +   when target codepage is CP_NONE. This is a workaround for
668 +   http://bugs.freepascal.org/view.php?id=30622.
669 +
670 + 2. DBLog option removed from TIBStatisticalService - not supported by server
671 +   since Firebird 1.5.
672 +
673 + 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
674 +   similar.
675 +
676 + 4. IBCodePage: updated mapping between codepages and character id.
677 +
678 + 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
679 +   Firebird. Character sets with a char width of two are not UTF16.
680 +
681 + 6. Strings received from the database are now always transliterated into UTF8
682 +   regardless of the database character set or connection character set. This
683 +   is for compatibility with the LCL.
684 +
685 + IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
686 +
687 + 1. IBBlob: Defer reading of blob until read method called. This avoids having to
688 +   read in an entire blob just to get the size of the blob. General performance
689 +   improvement when opening datasets containing blobs.
690 +
691 + 2. Clearing a  Blob now sets the corresponding field's modified flag.
692 +
693 + 3. IBLookupCombo: When not performing auto-complete, original query sort order
694 +   is now used.
695 +
696 + 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
697 +   determined.
698 +
699 + 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
700 +
701 + 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
702 +   lazarus 1.6.0
703 +
704 + 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
705 +   compilation error.
