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 +
472 +
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 +
618 + IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
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.
706 +
707 + IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
708 +
709 + 1. No character set specified for connection: when a text blob is retrieved, the
710 +  character set is determined by looking up the native character set using then
711 +  Firebird API. Otherwise a text mode blob is assumed to have the same character
712 +  set as the connection.
713 +
714 + 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
715 +   for Login Dialog returing a change to the database path.
716 +
717 + 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
718 +   to be changed from that given in the TIBDatabase/TIBServer component and for the
719 +   entered value to be saved on a project specific basis (design time only).
720 +
721 + 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
722 +   column fieldname. If they are the same then it is acts as a look up for the KeyValue
723 +   Otherwise, it sets the column text to the selected ListField Value.
724 +
725 + 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
726 +   column width.
727 +
728 + 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
729 +   and a case insensitive search is requested.
730 +
731 + 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
732 +   or column ListSource.
733 +
734 + 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
735 +   unprepare) when closing and the text has not changed.
736 +
737 + 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
738 +   Less likely to cause a cursor re-use error on Windows.
739 +
740 + 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
741 +   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
742 +
743 + 11. TIBTreeView: Guard against nil destination on record changed
744 +
745 + 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
746 +    string type with the code page set to reflect the returned field encoding after
747 +    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
748 +    earlier versions.
749 +
750 + 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
751 +    will now result in transliteration to the code page specified for the Firebird driver
752 +    if the assigned string has a different code page. FPC 3.0.0 onwards only.
753 +
754 + 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
755 +    is ignored and the lc_ctype value, when the database is opened, is set to align with
756 +    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
757 +    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
758 +    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
759 +    the GETACP is used to determine the Windows code page.
760 +
761 + 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
762 +    name used as the lc_ctype when the database was opened. Only valid while the
763 +    Database is connected.
764 +
765 + 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
766 +    id that corresponds to the DefaultCharSetName.
767 +
768 + IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
769 +
770 + 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
771 +   path is given and database attach fails due to access permission issues on the
772 +   temp directory or security database, then the attach is retried with "localhost:"
773 +   prefixing the databasename. This should avoid problems when the database has to
774 +   be accessed by a local (e.g. classic) server and libfbembed is used.
775 +
776 + 2. Windows: revised search order for Firebird DLL:
777 +     i.   The Firebird Embedded Server in the application Directory.
778 +     ii.  If the FIREBIRD environment variable is set then the directory this
779 +          points to is searched for the FB Client DLL and then then underlying
780 +          "bin" directory.
781 +     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
782 +          is used to locate the Firebird installation directory and the underlying
783 +          "bin" directory is searched for the FB Client DLL.
784 +     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
785 +          are searched for the FB Client DLL.
786 +     v.   The PATH Environment variable is used to search for the FB Client DLL.
787 +     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
788 +
789 + 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
790 +   See doc/readme.scriptengine and example applications.
791 +
792 + 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
793 +   simplify the use of the embedded firebird server on both Linux and Windows platforms.
794 +   See dpc/readme.localdatabase and example applications.
795 +
796 + 5. IBDynamicGrid: Reordering on column header click should now also work for
797 +   dynamic columns.
798 +
799 + 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
800 +   between incrementing/decrementing the lock count and signalling the event.
801 +
802 + IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
803 +
804 + 1.3.2 was never formally released and only made available as beta copies.
805 +
806 + 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
807 +
808 + 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
809 +
810 + 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
811 +
812 + 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
813 +   i.e. when it is a calculated field
814 +
815 + 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
816 +   This problem was due to a race condition between recalculating row heights and
817 +   determining which row was selected by the mouse click. The row height calculation
818 +   is now deferred by an extra trip round the message loop allowing the row to
819 +   be always calculated on the current grid layout rather than risking it being
820 +   calculated on the grid layout after the expanded row has been shrunk.
821 +
822 + 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
823 +   Windows.
824 +
825 + 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
826 +   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
827 +   to be determined at runtime. See doc/readme.charactersets.html.
828 +
829 + 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
830 +   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
831 +
832 + 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
833 +   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
834 +   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
835 +
836 +   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
837 +   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
838 +   implies no truncation.
839 +
840 + 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
841 +
842 + 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
843 +   (avoids "Not in Edit Mode" error).
844 +
845 + 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
846 +
847 + 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
848 +    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
849 +
850 + 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
851 +
852 + 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
853 +
854 + 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
855 +
856 + 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
857 +
858 + IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
859 +
860 + 1.   OnCloseUp Event Handler added to TDBLookupProperties
861 +
862 + 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
863 +     problem with row size when exception is called.
864 +
865 + 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
866 +
867 + 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
868 +     in a TCustomComboBox and ignores return key if in a TCustomMemo
869 +
870 + 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
871 +     keyed in i.e. when autocomplete not performed
872 +
873 + 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
874 +     console mode applications with all LCL required functions (builtin dialogs and
875 +     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
876 +     not included in your project, IBX should compile and link with a console mode program.
877 +     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
878 +     console mode application or the IDE will automatically assume that your
879 +     application is GUI based. Instead, you should include the ibexpressconsolemode package.
880 +
881 +     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
882 +     to use the built in dialogs and cursor management. IBDialogs is
883 +     included by default if "ibexpress" is in your project source's "uses" clause.
884 +     This should be the case for all projects created through the IDE. This is why
885 +     you do not want to add the ibexpress package to console mode applications. The
886 +     ibexpressconsolemode package has been created to allow console mode programs
887 +     to avoid adding LCL dependencies when using IBX, while still having the
888 +     unit search paths set up correctly.
889 +
890 +     Existing users should check to ensure that the "ibexpress" unit is included in
891 +     each project's source file (*.lpr).
892 +
893 +     You may find that in order for the IDE to recognise that ibexpressconsolemode
894 +     exists, you have to first open the package in the IDE and then close it. This
895 +     adds it to the most recently accessed packages list. To make it permanently
896 +     available, add the package name to lazarus' staticpackages.inc file.
897 +
898 +         Thanks to Julio Jiménez for suggesting support of console mode.
899 +
900 + 7.   SQL Parser can now accept quoted strings that include new lines
901 +
902 + 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
903 +     of text on start of edit. This is particularly useful when tabbing to a
904 +     column and then inserting text.
905 +
906 + 9.   New Examples provided for IB Services and ISQLMonitor.
907 +
908 + 10. Fix error when writing to blob streams that recorded only the last buffer
909 +    write in the blob stream. In most cases, this did not cause a problem as the
910 +    IB Blob Stream is written in a single write. However, with the TDBImage, write
911 +    of a graphic type prefix was lost which caused a problem when the image could
912 +        not be automatically recognised.
913 +
914 + 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
915 +    already open" errors due to random numbers used for the cursor name being identical.
916 +
917 + 12. IBTable: corrected error that could result in an "Index out of bounds" error
918 +    when opening the table and the Primary Key is the last or only column in the
919 +    table. Thanks to Rick Hoover for the fix.
920 +
921 + 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
922 +    of "UTF-8", and update list of available database character sets. Existing
923 +    users should check the current lc_ctype setting in their applications.
924 +
925 + IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
926 +
927 + 1.  Firebird Services: avoid List Index error when opening a service with an
928 +    empty Params property.
929 +
930 + 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
931 +    Link now set up in Loaded method - avoids occasional failure to apply
932 +    SQL markup on initial open.
933 +
934 + 3.  "Employees" example performance improvements when scrolling.
935 +
936 + 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
937 +    TFrame. Force recaching of selected frame to avoid GTK race (results in a
938 +    random image cached).
939 +
940 + 5.  DBControlGrid: Should now react to changes in panel height at run time.
941 +
942 + 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
943 +    even when further rows exist.
944 +
945 + 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
946 +    always be derived from panel height and setting this property can cause confusion.
947 +    Note for existing projects: to avoid a missing property error at run time,
948 +    each form using the DBControlGrid must be opened, updated and saved in the IDE
949 +    in order to remove the property value from the lfm.
950 +
951 +
952 + IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
953 +
954 + 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
955 +    call Prepare before setting parameter values.
956 +
957 + 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
958 +
959 + 3.  Code tidyup and more robust handling of dsql information result vector.
960 +
961 + 4.  Support for centralised handling of transaction status changes. TIBTransaction
962 +    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
963 +    and "AfterExecQuery". The first three are called after the same event is called
964 +    for an IBCustomDataSet descendent using the Transaction. The fourth is called
965 +    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
966 +    enable monitoring of transaction status changes for a given transaction to be
967 +    handled in a single place. For example, when a change to the dataset occurs
968 +    an indicator can be set that shows the user that in order to save changes,
969 +    the transaction should be committed.  Rather than doing this per dataset, this
970 +    can now be done per transaction.
971 +
972 + 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
973 +    the dataset is scrolled. However, any changes to the current row are, by default,
974 +    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
975 +    have a new property "DataSetCloseAction" that adds automatic posting of changes
976 +    on dataset close. If this property is set to dcDiscardChanges (default) then the
977 +    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
978 +    then IBX will attempt to post any unsaved changes before the dataset is closed
979 +    (and after the BeforeClose event handler is called). The exception is when the
980 +    dataset is being closed as a result of a transaction rollback. In this case,
981 +    no action is taken and any unsaved  changes are discarded. This avoids both
982 +    unnecessary overhead and the risk that a validation error may occur in the Post
983 +    raising an exception and thereby preventing a rollback.
984 +
985 + 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
986 +    In earlier versions, the Display Width was set to the maximum byte width rather than the character
987 +    width. Display Widths are now corrected by dividing by the max byte width per character.
988 +    For UTF8 character sets, the byte width is four and hence the Display Width will be
989 +    the byte width divided by 4. The byte width of each character set is determined
990 +    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
991 +    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
992 +
993 + 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
994 +
995 + 8.  IBLookupComboEditBox: List should now always be restored to full list when the
996 +    control loses focus. Default Key press default interval reduced to 200ms.
997 +
998 + 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
999 +    when dataset rows are less than visible rows.
1000 +
1001 + 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1002 +    does not exist or DataSet is empty. More responsive on dataset open. New event
1003 +    OnRestorePosition. Column sort disabled if no header row.
1004 +
1005 + 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1006 +    while dataset state is dsInsert. Avoids posting errors.
1007 +
1008 + 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1009 +    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1010 +
1011 + 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1012 +
1013 + 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1014 +    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1015 +    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1016 +    always "posts" the current record regardless or whether or not it may be more appropriate
1017 +    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1018 +    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1019 +    as the first action of the "Post" method and allows the handler to convert the Post
1020 +    into a Cancel if that is the appropriate action on moving to a different row. This is
1021 +    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1022 +    raised here, but it may still be more appropriate to validate a post and signal
1023 +    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1024 +
1025 + 15. On Unix derived systems, the Firebird library name can now be given as a colon
1026 +    separated list. Each library name on the list is tried in turn, in left to right
1027 +    order with the first found being used as the firebird library. By default, on Linux,
1028 +    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1029 +    overidden by the FBLIB environment variable or the OnGetLibraryName function.
1030 +
1031 +    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1032 +    then it will still attempt to access the database via the Firebird Server and will
1033 +    require a username and password. If only the pathname is given, then the username
1034 +    and password should be omitted and the unix file permissions are used to grant
1035 +    access.
1036 +
1037 + IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1038 +
1039 + 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1040 +    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1041 +    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1042 +    corresponds to a row of the linked DataSource. Any data aware control on the
1043 +    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1044 +
1045 + 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1046 +   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1047 +   takes place during database access. This may be useful when there are performance issues with
1048 +   the change of cursor. Setting the property to false suppresses the change of cursor.
1049 +
1050 + 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1051 +   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1052 +   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1053 +   making all changes permanent immediately rather than when the transaction is explicitly
1054 +   committed.
1055 +
1056 + 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1057 +   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1058 +

1061 + Development version only.
1062 +
1063 + IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1064 +
1065 + 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1066 +   This is typically used during an "OnBeforeOpen" event handler to manipulate the
1067 +   "Where" and "Having" clauses to implement user specified filters of arbitrary
1068 +   complexity.
1069 +
1070 + 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1071 +   three new data aware controls dependent on IBX and which make use of the SQL Parser.
1072 +   These are:
1073 +
1074 +   - TIBLookupComboEditBox
1075 +   - TIBDynamicGrid
1076 +   - TIBTreeview
1077 +
1078 +   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1079 +   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1080 +   to revise the available list and restrict it to items that are prefixed by the
1081 +   typed text (either case sensitive or case insensitive). Autoinsert allows a
1082 +   newly typed entry to be added to the list dataset and included in the available
1083 +   list items.
1084 +
1085 +   TIBDynamicGrid is a TDBGrid descendent that provides for:
1086 +   - automatic resizing of selected columns to fill the available row length
1087 +   - automatic positioning and sizing of a "totals" control, typically at the
1088 +     column footer, on a per column basis.
1089 +   - DataSet resorting on header row click, sorting the dataset by the selected column.
1090 +     A second click on the same header cell reversed the sort order.
1091 +   - Support for a "Panel Editor". That is on clicking the indicator column, the row
1092 +     is automatically expanded and a panel superimposed on it. The panel can have any
1093 +     number of child controls, typically data aware controls with the same datasource
1094 +     as the grid allowing for editing of additional fields and more complex editors.
1095 +   - Reselection of the same row following resorting.
1096 +   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1097 +     Its properties are specified on a per column basis and allows for one or more
1098 +     columns to have their values selected from a list provided by a dataset.
1099 +     Autocomplete and autoinsert are also available. The existing picklist editor
1100 +     is unaffected by the extension.
1101 +
1102 +   TIBTreeView is a data aware TCustomTreeView.
1103 +
1104 + 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1105 +   zero scale will no longer return an error. An Int64 will be returned instead.
1106 +
1107 + 4. TIBTransaction now has events for Before and After Transaction End and a new function
1108 +   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1109 +
1110 + 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1111 +   repeated multiple times.
1112 +
1113 + 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1114 +   check used to get in the way of using Stored Procedures, and "Update or Insert"
1115 +   statements.
1116 +
1117 + 7. Insert, Modify and Delete property Editors now support Query Generation from
1118 +   Stored Procedures.
1119 +
1120 + 8. Three new examples illustrate the use of the new IB Controls
1121 +
1122 +
1123 + IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1124 +
1125 + 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1126 +   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1127 +   Gabor Boros for reporting this problem and for testing the improvements).
1128 +
1129 + 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1130 +   See readme.field+param.names in the doc folder.
1131 +
1132 + 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1133 +   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1134 +
1135 + 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1136 +
1137 + 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1138 +   actions.
1139 +
1140 + 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1141 +   thanks to Yuriy Kopnin for pointing this out).
1142 +
1143 + 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1144 +
1145 + 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1146 +   for both fields and parameter setting.
1147 +
1148 + 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1149 +   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1150 +
1151 + 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1152 +    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1153 +
1154 + 11. TIBTable now has a property editor for "MasterFields"
1155 +
1156 + 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1157 +    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1158 +
1159 + 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1160 +    of settings is unrecognised. Selecting this radio button has no effect on the settings.
1161 +

1168 +
1169 + 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1170 +   it is null. This allows for alternative user defined setting of the generator
1171 +
1172 +   Many thanks to Julio Jiménez for this fix
1173 +
1174 + 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1175 +   and suggests that the user may have forgotten to install it.
1176 +
1177 + IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1178 +
1179 + 1. Conditional compilation used to limit registration of TIntegerField to
1180 +   Lazarus versions less than 1.1
1181 +
1182 + 2. When a database connection is created, character set is now by default set
1183 +   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1184 +   1250 to 1254.
