1 tony 231 IBX Change Log version (2.3-0) Sat, 14 Apr 2018 16:47:40 +0100
2 tony 101
3 tony 209 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
4     all previous copies of the IBX source code tree before installing this release.
6     The IBX packages used by most users have not changed, with one exception. The
7     IBServices unit has been moved to the package iblegacyServices.lpk. To continue
8     to use the IBServices unit in your applications, please add the iblegacyServices
9     to the list of dependencies. To do this, open the Project Inspector and select
10     Add->New Requirement and select "ibLegacyServices" from the list of available
11     packages.
13     1. New unit IBXServices. The IBXServices unit is a re-architectured update of
14     the IBServices unit providing what is intended to be a clearer and easier to
15     use set of IB Services components. See Chapter 10 of the IBX User Guide for
16     more information and the guide to "Firebird Service Management Using IBX".
17     As indicated above, the legacy services components are still available and
18     provided in a separate package. There is no need to update working applications
19     using the older versions except for an additional package dependency.
21     2. The IBX packages and source code tree have been re-organised in an attempt to
22     finally get rid of the "duplicate ppu" warnings. This re-organisation should
23     not affect existing users. Section 2.3 of the IBX User Guide describes the
24     new set of IBX packages.
26     3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
27     updated to use the new Services API components.
29     4. The iblocal package has been updated to use the new Services API components.
31     5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
32     TIBXSecurityService. It had been wrongly classified in the previous version
33     as a per database configuration item. It is global to a server and hence
34     correctly positioned as part of the Security Package. In the DBAdmin example,
35     the setting has moved to the mappings page.
37     6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
38     are ignored.
40     7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
41     closed before the database is dropped. Before and After Disconnect event handlers
42     are also fired.
44     8. TIBTransaction: OnStartTransaction event now fires every time the transaction
45     is started and not just the first time.
47     9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
48     depenendency with comp type.
50     10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
52     11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
53     then this is recognised and not ignored.
55     12. TIBDataSet, TIBQuery, TIBTable: additions:
56     function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
57     function GetPerfStatistics(var stats: TPerfCounters): boolean;
58     property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
60     GetRowsAffected returns the affected row counts from the last insert/update/delete
61     if EnableStatistics = true then GetPerfStatistics returns the current stats
62     counters for the select query. Note: stats accumulate after each fetch from
63     the database. To get total query cost after open, call the "Last" method
64     and then GetPerfStatistics.
66     See ibx/examples/consolemode for an example of the use of GetPerfStatistics
68     13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
69     in parenthesises.
71     14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
72     SQL identifiers are always delimited by double quotes. If false, then they are
73     only delimited if the identifier is a reserved word, contains lower case or special
74     characters. Set this property to true to retain previous behaviour.
76     15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
77     are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
79     16. TIBDataSet, TIBQuery, TIBTable: addition:
80     property MasterDetailDelay: integer {defaults to zero}
82     When non-zero and the dataset is a detail table referencing a master table
83     through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
84     then a synchronisation delay is added (in milliseconds) between the master
85     row changing and the detail dataset being re-opened. If the master dataset
86     is scrolled before the delay expires then the delay is reset. This can be used
87     to avoid performance overheads when scrolling through a large master dataset.
89     Note: uses fptimer and hence requires a thread manager. Under Linux the
90     chreads unit must be included in your project. TTimer is not used in order
91 tony 213 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
92 tony 209
93     17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
94     with Extract Option eoDatabase.
96     18. TIBLookupComboEditBox: Workaround added for
97 tony 225 When a deLayoutChanged event is reported on the ListSource dataset, the
98 tony 209 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
99     relationship with the control's datasource (master).
101 tony 221 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
103 tony 226 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
104 tony 221 stubs. Pedantic fix really, as procedures output in dependency order anyway.
106 tony 226 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
107 tony 221 DDL (Firebird 3 and later only).
109 tony 225 22. TIBLookupComboBox Autocomplete Fixes:
110     i. Only appended text is now selected after autocomplete.
111     ii. Uppercase keys no longer ignored for autocomplete.
112     iii. Retain Prefix case is now honoured correctly.
113     iv. When a DataSource is assigned, typing after autocomplete now extends prefix
114     before autocomplete performed. i.e. behaviour now the same as when
115     no DataSource assigned.
117 tony 226 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
118 tony 225 between SQL statements.
120     24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
121     ObjectNames are converted to upper case before matching against metadata object
122     names, unless the objectname is delimited by double quotes, in which case, the
123     double quotes are removed and the remaining string is used (unmodified) to match
124     against the metadata object name.
126     If true then the ObjectName is used as is without modification and matched
127     against the metadata object name. No attempt is made to remove double quotes.
129 tony 226 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
130     with eoTrigger, these extract types can be used to select only Database Triggers,
131     or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
133 tony 227 26. TIBXScript: If an exception occurs during the processing of a statement, the
134     statement separate character is now reset to the default (';').
136 tony 229 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
138     28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
139     a commit or reconnect statement and instead activated only when next SQL statement
140     is executed.
142     29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
144     30. TIBXScript: case insensitive regex now used when matching statements instead of
145     converting statement to upper case.
147     31. TIBExtract: metadata comments now supported. New published property
148     IncludeMetaDataComments (default true). If true then metadata comments included
149     in extracted DDL. New Extract Object member eoComments. This may be used with
150     ExtractObject method to list all metadata comments.
152     32. TIBExtract: ListObjectNames method added.
154 tony 231 33. Updated Database component editor to support additional connection string
155     types.
157 tony 209 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
161 tony 151 RELEASE.
165 tony 107 1. IBExtract: Identity columns - add additional check for null column for generator name.
166 tony 101
167     2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
168     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
169 tony 107 information). However, this is also a very useful mechanism for returning updated computed by
170     column values. Values returned as a result of executing an Insert or Update statement
171     replace existing values in the current row for each corresponding column.
172 tony 101
173 tony 107 Previously, if a dataset's select query included read only (computed by) fields then
174     an automatic row refresh was performed after an insert or update query had been processed,
175     irrespective of the setting of the "ForcedUpdates" property. This has changed such
176     that an automatic refresh is no longer performed if an insert or update query contains
177     a returning clause that updates one or more fields on the current row. A full row
178     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
179     field values and the select query contains read only fields. Use of Insert/update
180 tony 123 returning should be significantly more efficient than executing a refresh query.
181 tony 107
182     This behaviour change is intended to be backwards compatible and there should be no need to change
183     existing programs, other than to improve performance by using the new capability.
185 tony 118 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
186     they are called when the dataset row is being deleted, there is no value in
187     updating the current record from the query result. Instead, a new event handler
188     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
189     an OnDeleteReturning event handler is provided then it is called with the IResults returned
190     by the query. The event handler can then interrogate the query results and
191     perform whatever action is necessary. For example to confirm, to the user,
192     the deletion of a row with the returned values.
194     4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
195 tony 107 any Computed By or Identity Columns. The IBTables example has been updated to
196     illustrate the computation of the employee Full Name on update.
198 tony 118 5. TIBTable: The GeneratorField property is now published.
199 tony 107
200 tony 118 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
201 tony 101 When InsertSQL is generated, the Identity columns are not included in the list of values to
202     be inserted. A RETURNING clause is added to the insert statement to return the value of
203     each Identity column after the insert is executed.
205 tony 118 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
206 tony 107 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
207     Insert..Returning clause.
208 tony 104
209 tony 118 8. TIBGenerator: small performance improvement by not preparing query each time
210 tony 107 a new value is generated.
211 tony 104
212 tony 118 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
213 tony 107
214 tony 118 10. Property editors will now sync table name to a System Table when "Include System
215     Tables" is selected and the query is for a System Table.
216 tony 105
217 tony 118 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
218 tony 107 values are no longer converted to milliseconds from TDateTime and then back again
219     to TDateTime (the conversion to milliseconds is the default TDataset approach).
220 tony 105
221 tony 118 12. Property Editors handling of Stored Procedures.
222 tony 107 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
223     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
224     query).
225     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
226 tony 106
227 tony 118 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
228 tony 107 can be used to select a package. If non-empty, the stored procedure name is
229     expected to be a stored procedure defined in the specified package and the
230     generated SQL will be as required for a stored procedure located in a package.
232 tony 118 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
233 tony 107 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
234     which a stored procedure can be selected. With no package name selected, non-package
235     stored procedures are listed.
237 tony 118 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
238 tony 109 for password on reconnect.
239 tony 107
240 tony 143 16. TIBDatabase: use IAttachment for connection default character set id, code page
241 tony 118 and character set name.
242 tony 109
243 tony 118 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
244     DB info lookups"
246 tony 143 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
247 tony 118
248 tony 127 19. Add a property Editor for TIBUpdate.RefreshSQL.
249 tony 118
250 tony 139 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
251     parameters. This stops an exception being raised when the field cannot be
252     located in the record buffer.
253 tony 127
254 tony 141 21. Property Editors now automatically include System Tables when opened and when the query table
255     is a System Table.
256 tony 139
257 tony 150 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
258 tony 143 This avoids errors due to a stale SQRB or SRB being used for the next query.
259 tony 141
260 tony 143 23. IBServices: Service attach parameters now include "expected_db". This is used to
261     add the SPB item isc_spb_expected_db. This names a database using
262     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
263     database. examples/services re-written to illustrate use of "expected_db".
264 tony 141
265 tony 143 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
266     This avoids truncated backups when the server returns a timeout (busy) response.
268     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
270     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
271     databasenames. These are respectively expanded to the local system's temp directory
272 tony 150 (including trailing delimiter) or to a prescribed data directory (including
273 tony 143 trailing delimiter). Under Unix systems the data directory is a hidden directory
274     in the user's home directory. The hidden directory name is either the string returned
275     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
276     Under Windows, the directory is the same as the Data Directory as decribed
277     above but instead prefixed by the User's application data path. These may be
278 tony 150 used to improve application portability for Personal Databases.
279 tony 143
280     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
281     this has not worked for a long time and is not useful either. FieldDefs should be
282     managed using the Fields Editor as with any other dataset. To access the fields
283     editor for a TIBTable component, double click on the component. The fields editor
284     is then displayed.
286     28. TIBDatabaseInfo: new properties/function
287     * DateDBCreated (returns date/time database created)
288     * TransactionCount (returns no. of active transactions)
289     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
290     * PagesFree (Firebird 3 or later)
291     * PagesUsed (Firebird 3 or later)
292     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
293     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
295     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
297     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
299     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
300     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
302     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
303     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
304     firing during backup and restore.
306     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
307     for verbose output using the new property "StatisticsRequested".
308     see
310     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
312     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
313     palette. This uses the online validation feature added in Firebird 2.5. The
314     services's properties enable inclusion/exclusion of tables and indexes using
315     regular expressions. See.
318     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
319     option on a database.
321     37. TIBCustomService: Assign method implemented to allow copying of service login
322     context between service API components. "Detach" method now only detaches
323     service when last reference to the service interface detaches. Tidy up of
324     code for SetActive and Attach methods including password hiding.
326 tony 150 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
327 tony 143 and used to determine the auth method and protocol used for the connection.
329     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
330     a Create Database Statement generated by IBX.
332     40. All IBServices now have an additional published property "PortNo". This may
333     be set to a non-standard port number when necessary. If zero then the default
334     port number is used.
336     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
337     and not just the mouse.
339     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
341     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
342     image index and selected image index for each node to be set from a database field.
344     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
345     then database schema includes grants to all users. If not present then the
346     only user grants included are those to User PUBLIC.
348     45. TIBTreeView: performance improvement. When expanding include both expanded node
349     and child nodes in dataset.
352 tony 90 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
353 tony 56
354     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
355     changes.
357 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
358     Bug could result in truncated multi-byte character set values.
360 tony 60 3. Changes consequential on moving fbintf character set utility functions from
361     IFirebirdAPI to IAttachment.
363 tony 62 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
365 tony 64 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
366     results in autocomplete ignoring prefix text.
368 tony 65 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
369     entering a new name into the text box.
371 tony 66 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
372     Firebird rather than recomputing it.
374 tony 67 8. Property Editor positioning tidy up: All IBX Property editors should now be
375     screen centre. Previously some were "poDesigned" which may be inappropriate
376     for multi monitor desktops.
378 tony 80 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
380     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
381     a transaction and always reset the object.
383     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
385     13. TIBXScript: Allow for override of database filename in Create Database statements.
387     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
388     to a gbak format archive.
390     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
392     16. IBLocaldb: Drop database if error creating an empty database.
394     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
395     unless selected node not in current dataset.
397     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
398     to TIBCustomService, and IBlocalDB code tidy up.
400     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
401     behaviour due to uninitialised variable.
403     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
404     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
406     21. IBSQL: When Database changed ensure that all resources are freed.
408     22. IBCustomDataset: When database changed ensure that queries an unprepared.
410 tony 84 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
411     * Line Wrap on SQL Token boundaries (on user command)
412     * auto-complete table names in drop down list of table names
413     * Double click on tablename or field name adds to SQL text
414 tony 80
415     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
417     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
418     TVariantArray. Seems to avoid memory corruption in Windows (probably a
419     workaround for a problem in fpc 3.0.4 win64).
421     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
423 tony 83 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
425 tony 51 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
426 tony 49
427 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
428 tony 49 include remote system name.
430     2. TIBExtract: No longer include comment header and COMMIT statement for empty
431     tables when data included in output.
433     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
434     and timing information to be written to stdout. This may be used to locate
435     performance bottlenecks.
437     4. SQLParser: only call "OnChanging" event handler when value is different.
439     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
441 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
442     that BindFields is called when the query is next activated. Avoids FieldName
443     not found error.
445 tony 80 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
446     purpose and allows the programmer to define any action they want for Update, Insert
447     or Delete. This may be complex SQL (similar to a Trigger), application specific
448     filtering of updates, or use of statements such as Grant or Revoke instead of
449     normal DML. See User Manual for more information.
451 tony 47 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
452 tony 45
453 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
454 tony 45
455 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
457     3. TIBExtract: data formatted as Charset set "octets" is now output using
458     hexadecimal notation.
460     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
461     using a simple XML format.
463     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
464     grants to these objects.
466     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
467     dependency problems restoring complex databases.
469     7. TIBXScript: This component has been restructured to allow for the processing of
470     embedded XML in INSERT statements and to support interactive sources in addition
471     to non-interactive data sources such as files.
473     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
475     9. TIBXScript: ISQL compatiable Set statements are now supported:
477     SET TERM
479     SET BAIL
480     SET ECHO
481     SET COUNT
482     SET STATS
483     SET NAMES <character set>
485     10. IBVersion unit added to hold current IBX Version Number information.
487     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
488     and domain definitions.
490     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
491     fully supported.
493     13. TIBExtract: when a database dump includes data, the generator values are now also set.
495     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.

499 tony 50 See also doc/IBX4LazarusGuide.pdf for important information on
500 tony 45 upgrading to IBX2.
502     1. Size property of TIBStringField is now the width in characters of the field
503     and not the byte length. This applies only to multi-byte character sets such
504     as UTF8. The original approach aligned with TStringField. However, the TStringField
505     code is not recognised as a bug and hence this change to align the behaviour.
506     The TStringField change is expected in fpc 3.2.0.
508     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
509     true (default) then Size property value saved in the lfm is ignored. Size is
510     always set from the dynamic information read from the database. It is unclear
511     why anyone would want to override this and set Size to false.
513     3. ibxscript: should now handle correctly a Case..End statement within a procedure
514     block.
516     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
517     exist when an attempt is made to connect to it (run time only) then an attempt
518     is made to create the database.
520     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
521     has been successfully created as a result of a call to CreateDatabase or when
522     creating a database after it was found not to exist.
524     6. DBControlGrid: a race condition could result in the wrong row image being
525     written to the cache. This has been avoided by a trip round the message
526     loop before rendering the row image.
528     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
529     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
530     known to risk corrupt rendering of row images when the control is first
531     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
532     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
534     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
535     a TDateEdit control located on an editor panel.
537     9. TIBExtract: brought up-to-date plus many bug fixes.
539     10. DBControlGrid: Removed memory leak when updating rows.
541     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
543 tony 43 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
545     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
546     when target codepage is CP_NONE. This is a workaround for
549     2. DBLog option removed from TIBStatisticalService - not supported by server
550     since Firebird 1.5.
552     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
553     similar.
555     4. IBCodePage: updated mapping between codepages and character id.
557     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
558     Firebird. Character sets with a char width of two are not UTF16.
560     6. Strings received from the database are now always transliterated into UTF8
561     regardless of the database character set or connection character set. This
562     is for compatibility with the LCL.
564 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
565 tony 41
566     1. IBBlob: Defer reading of blob until read method called. This avoids having to
567     read in an entire blob just to get the size of the blob. General performance
568     improvement when opening datasets containing blobs.
570     2. Clearing a Blob now sets the corresponding field's modified flag.
572     3. IBLookupCombo: When not performing auto-complete, original query sort order
573     is now used.
575     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
576     determined.
578     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
580     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
581     lazarus 1.6.0
583     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
584     compilation error.
586 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
588     1. No character set specified for connection: when a text blob is retrieved, the
589     character set is determined by looking up the native character set using then
590     Firebird API. Otherwise a text mode blob is assumed to have the same character
591     set as the connection.
593     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
594     for Login Dialog returing a change to the database path.
596     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
597     to be changed from that given in the TIBDatabase/TIBServer component and for the
598     entered value to be saved on a project specific basis (design time only).
600     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
601     column fieldname. If they are the same then it is acts as a look up for the KeyValue
602     Otherwise, it sets the column text to the selected ListField Value.
604     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
605     column width.
607     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
608     and a case insensitive search is requested.
610     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
611     or column ListSource.
613     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
614     unprepare) when closing and the text has not changed.
616     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
617     Less likely to cause a cursor re-use error on Windows.
619     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
620     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
622     11. TIBTreeView: Guard against nil destination on record changed
624     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
625     string type with the code page set to reflect the returned field encoding after
626     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
627     earlier versions.
629     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
630     will now result in transliteration to the code page specified for the Firebird driver
631     if the assigned string has a different code page. FPC 3.0.0 onwards only.
633     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
634     is ignored and the lc_ctype value, when the database is opened, is set to align with
635     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
636     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
637     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
638     the GETACP is used to determine the Windows code page.
640     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
641     name used as the lc_ctype when the database was opened. Only valid while the
642     Database is connected.
644     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
645     id that corresponds to the DefaultCharSetName.
647 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
649     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
650     path is given and database attach fails due to access permission issues on the
651     temp directory or security database, then the attach is retried with "localhost:"
652     prefixing the databasename. This should avoid problems when the database has to
653     be accessed by a local (e.g. classic) server and libfbembed is used.
655     2. Windows: revised search order for Firebird DLL:
656     i. The Firebird Embedded Server in the application Directory.
657     ii. If the FIREBIRD environment variable is set then the directory this
658     points to is searched for the FB Client DLL and then then underlying
659     "bin" directory.
660     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
661     is used to locate the Firebird installation directory and the underlying
662     "bin" directory is searched for the FB Client DLL.
663     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
664     are searched for the FB Client DLL.
665     v. The PATH Environment variable is used to search for the FB Client DLL.
666     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
668     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
669     See doc/readme.scriptengine and example applications.
671     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
672     simplify the use of the embedded firebird server on both Linux and Windows platforms.
673     See dpc/readme.localdatabase and example applications.
675     5. IBDynamicGrid: Reordering on column header click should now also work for
676     dynamic columns.
678     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
679     between incrementing/decrementing the lock count and signalling the event.
681 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
683 tony 37 1.3.2 was never formally released and only made available as beta copies.
685 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
687     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
689     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
691     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
692     i.e. when it is a calculated field
694     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
695     This problem was due to a race condition between recalculating row heights and
696     determining which row was selected by the mouse click. The row height calculation
697     is now deferred by an extra trip round the message loop allowing the row to
698     be always calculated on the current grid layout rather than risking it being
699     calculated on the grid layout after the expanded row has been shrunk.
701     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
702     Windows.
704     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
705     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
706 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
707 tony 35
708     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
709 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
710 tony 35
711     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
712     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
713 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
714 tony 35
715     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
716     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
717     implies no truncation.
719     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
721     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
722     (avoids "Not in Edit Mode" error).
724     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
726     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
727     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
729     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
731     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
733     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
735     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
737 tony 33 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
738 tony 31
739     1. OnCloseUp Event Handler added to TDBLookupProperties
741     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
742     problem with row size when exception is called.
744     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
746     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
747     in a TCustomComboBox and ignores return key if in a TCustomMemo
749     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
750     keyed in i.e. when autocomplete not performed
752 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
753     console mode applications with all LCL required functions (builtin dialogs and
754     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
755     not included in your project, IBX should compile and link with a console mode program.
756     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
757     console mode application or the IDE will automatically assume that your
758     application is GUI based. Instead, you should include the ibexpressconsolemode package.
759 tony 31
760     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
761     to use the built in dialogs and cursor management. IBDialogs is
762 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
763 tony 31 This should be the case for all projects created through the IDE. This is why
764     you do not want to add the ibexpress package to console mode applications. The
765     ibexpressconsolemode package has been created to allow console mode programs
766     to avoid adding LCL dependencies when using IBX, while still having the
767     unit search paths set up correctly.
769 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
770     each project's source file (*.lpr).
772 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
773     exists, you have to first open the package in the IDE and then close it. This
774     adds it to the most recently accessed packages list. To make it permanently
775     available, add the package name to lazarus' file.
777 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
778 tony 31
779     7. SQL Parser can now accept quoted strings that include new lines
781     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
782     of text on start of edit. This is particularly useful when tabbing to a
783     column and then inserting text.
785     9. New Examples provided for IB Services and ISQLMonitor.
787     10. Fix error when writing to blob streams that recorded only the last buffer
788     write in the blob stream. In most cases, this did not cause a problem as the
789     IB Blob Stream is written in a single write. However, with the TDBImage, write
790     of a graphic type prefix was lost which caused a problem when the image could
791     not be automatically recognised.
793     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
794 tony 33 already open" errors due to random numbers used for the cursor name being identical.
795 tony 31
796     12. IBTable: corrected error that could result in an "Index out of bounds" error
797     when opening the table and the Primary Key is the last or only column in the
798     table. Thanks to Rick Hoover for the fix.
800 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
801     of "UTF-8", and update list of available database character sets. Existing
802     users should check the current lc_ctype setting in their applications.
803 tony 29
804 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
806 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
807     empty Params property.
809     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
810     Link now set up in Loaded method - avoids occasional failure to apply
811     SQL markup on initial open.
813     3. "Employees" example performance improvements when scrolling.
815     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
816     TFrame. Force recaching of selected frame to avoid GTK race (results in a
817     random image cached).
819     5. DBControlGrid: Should now react to changes in panel height at run time.
821     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
822     even when further rows exist.
824     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
825     always be derived from panel height and setting this property can cause confusion.
826     Note for existing projects: to avoid a missing property error at run time,
827     each form using the DBControlGrid must be opened, updated and saved in the IDE
828     in order to remove the property value from the lfm.
831 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
832 tony 27
833     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
834     call Prepare before setting parameter values.
836     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
838     3. Code tidyup and more robust handling of dsql information result vector.
840     4. Support for centralised handling of transaction status changes. TIBTransaction
841     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
842     and "AfterExecQuery". The first three are called after the same event is called
843     for an IBCustomDataSet descendent using the Transaction. The fourth is called
844     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
845     enable monitoring of transaction status changes for a given transaction to be
846     handled in a single place. For example, when a change to the dataset occurs
847     an indicator can be set that shows the user that in order to save changes,
848     the transaction should be committed. Rather than doing this per dataset, this
849     can now be done per transaction.
851     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
852     the dataset is scrolled. However, any changes to the current row are, by default,
853     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
854     have a new property "DataSetCloseAction" that adds automatic posting of changes
855     on dataset close. If this property is set to dcDiscardChanges (default) then the
856     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
857     then IBX will attempt to post any unsaved changes before the dataset is closed
858     (and after the BeforeClose event handler is called). The exception is when the
859     dataset is being closed as a result of a transaction rollback. In this case,
860     no action is taken and any unsaved changes are discarded. This avoids both
861     unnecessary overhead and the risk that a validation error may occur in the Post
862     raising an exception and thereby preventing a rollback.
864     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
865     In earlier versions, the Display Width was set to the maximum byte width rather than the character
866     width. Display Widths are now corrected by dividing by the max byte width per character.
867     For UTF8 character sets, the byte width is four and hence the Display Width will be
868     the byte width divided by 4. The byte width of each character set is determined
869     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
870     system table. (see also
872     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
874     8. IBLookupComboEditBox: List should now always be restored to full list when the
875     control loses focus. Default Key press default interval reduced to 200ms.
877     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
878     when dataset rows are less than visible rows.
880     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
881     does not exist or DataSet is empty. More responsive on dataset open. New event
882     OnRestorePosition. Column sort disabled if no header row.
884     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
885     while dataset state is dsInsert. Avoids posting errors.
887     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
888     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
890     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
892     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
893     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
894     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
895     always "posts" the current record regardless or whether or not it may be more appropriate
896     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
897     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
898     as the first action of the "Post" method and allows the handler to convert the Post
899     into a Cancel if that is the appropriate action on moving to a different row. This is
900     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
901     raised here, but it may still be more appropriate to validate a post and signal
902     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
904     15. On Unix derived systems, the Firebird library name can now be given as a colon
905     separated list. Each library name on the list is tried in turn, in left to right
906     order with the first found being used as the firebird library. By default, on Linux,
907     the library name list is ''. This can be
908     overidden by the FBLIB environment variable or the OnGetLibraryName function.
910     Note: when using the, if you prefix the database name with "localhost:"
911     then it will still attempt to access the database via the Firebird Server and will
912     require a username and password. If only the pathname is given, then the username

918     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
919     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
920     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
921 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
922 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
924     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
925 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
926 tony 23 takes place during database access. This may be useful when there are performance issues with
927     the change of cursor. Setting the property to false suppresses the change of cursor.
929     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
930     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
931     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
932     making all changes permanent immediately rather than when the transaction is explicitly
933     committed.
935 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
936 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

944     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
945     This is typically used during an "OnBeforeOpen" event handler to manipulate the
946     "Where" and "Having" clauses to implement user specified filters of arbitrary
947     complexity.
949     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
950     three new data aware controls dependent on IBX and which make use of the SQL Parser.
951     These are:
953     - TIBLookupComboEditBox
954     - TIBDynamicGrid
955     - TIBTreeview
957     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
958     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
959     to revise the available list and restrict it to items that are prefixed by the
960 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
961 tony 21 newly typed entry to be added to the list dataset and included in the available
962     list items.
964     TIBDynamicGrid is a TDBGrid descendent that provides for:
965     - automatic resizing of selected columns to fill the available row length
966     - automatic positioning and sizing of a "totals" control, typically at the
967     column footer, on a per column basis.
968     - DataSet resorting on header row click, sorting the dataset by the selected column.
969     A second click on the same header cell reversed the sort order.
970     - Support for a "Panel Editor". That is on clicking the indicator column, the row
971     is automatically expanded and a panel superimposed on it. The panel can have any
972     number of child controls, typically data aware controls with the same datasource
973     as the grid allowing for editing of additional fields and more complex editors.
974     - Reselection of the same row following resorting.
975     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
976     Its properties are specified on a per column basis and allows for one or more
977     columns to have their values selected from a list provided by a dataset.
978     Autocomplete and autoinsert are also available. The existing picklist editor
979     is unaffected by the extension.
981     TIBTreeView is a data aware TCustomTreeView.
983     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
984     zero scale will no longer return an error. An Int64 will be returned instead.
986     4. TIBTransaction now has events for Before and After Transaction End and a new function
987     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
989     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
990     repeated multiple times.
992     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
993     check used to get in the way of using Stored Procedures, and "Update or Insert"
994     statements.
996     7. Insert, Modify and Delete property Editors now support Query Generation from
997     Stored Procedures.
999     8. Three new examples illustrate the use of the new IB Controls

1003 tony 19
1004     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1005     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1006     Gabor Boros for reporting this problem and for testing the improvements).
1008     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1009     See readme.field+param.names in the doc folder.
1011     3. IBX SQL Editors will now automatically add double quotes around column names when the database
1012     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1014     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1016     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1017     actions.
1019     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1020     thanks to Yuriy Kopnin for pointing this out).
1022     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1024     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1025     for both fields and parameter setting.
1027     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1028     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1030     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1031     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1033     11. TIBTable now has a property editor for "MasterFields"
1035     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1036     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1038     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1039     of settings is unrecognised. Selecting this radio button has no effect on the settings.

1044     1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.

1048     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1049     it is null. This allows for alternative user defined setting of the generator
1051     Many thanks to Julio Jiménez for this fix
1053     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1054     and suggests that the user may have forgotten to install it.

1058     1. Conditional compilation used to limit registration of TIntegerField to
1059     Lazarus versions less than 1.1
1061     2. When a database connection is created, character set is now by default set
1062     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1063     1250 to 1254.

1072 tony 7
1073     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1074     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1076     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1077     package is changed to do this (which it should do).
1079     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1081     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1083     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1085     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1087     4. Property editors should now correctly resize.
1089     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1090     (restored original functionality)
1092     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1093     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
