1 tony 229 IBX Change Log version (2.3-0) Tue, 10 Apr 2018 14:27:10 +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 209 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
158 tony 151 RELEASE.
162 tony 107 1. IBExtract: Identity columns - add additional check for null column for generator name.
163 tony 101
164     2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
165     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
166 tony 107 information). However, this is also a very useful mechanism for returning updated computed by
167     column values. Values returned as a result of executing an Insert or Update statement
168     replace existing values in the current row for each corresponding column.
169 tony 101
170 tony 107 Previously, if a dataset's select query included read only (computed by) fields then
171     an automatic row refresh was performed after an insert or update query had been processed,
172     irrespective of the setting of the "ForcedUpdates" property. This has changed such
173     that an automatic refresh is no longer performed if an insert or update query contains
174     a returning clause that updates one or more fields on the current row. A full row
175     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
176     field values and the select query contains read only fields. Use of Insert/update
177 tony 123 returning should be significantly more efficient than executing a refresh query.
178 tony 107
179     This behaviour change is intended to be backwards compatible and there should be no need to change
180     existing programs, other than to improve performance by using the new capability.
182 tony 118 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
183     they are called when the dataset row is being deleted, there is no value in
184     updating the current record from the query result. Instead, a new event handler
185     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
186     an OnDeleteReturning event handler is provided then it is called with the IResults returned
187     by the query. The event handler can then interrogate the query results and
188     perform whatever action is necessary. For example to confirm, to the user,
189     the deletion of a row with the returned values.
191     4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
192 tony 107 any Computed By or Identity Columns. The IBTables example has been updated to
193     illustrate the computation of the employee Full Name on update.
195 tony 118 5. TIBTable: The GeneratorField property is now published.
196 tony 107
197 tony 118 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
198 tony 101 When InsertSQL is generated, the Identity columns are not included in the list of values to
199     be inserted. A RETURNING clause is added to the insert statement to return the value of
200     each Identity column after the insert is executed.
202 tony 118 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
203 tony 107 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
204     Insert..Returning clause.
205 tony 104
206 tony 118 8. TIBGenerator: small performance improvement by not preparing query each time
207 tony 107 a new value is generated.
208 tony 104
209 tony 118 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
210 tony 107
211 tony 118 10. Property editors will now sync table name to a System Table when "Include System
212     Tables" is selected and the query is for a System Table.
213 tony 105
214 tony 118 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
215 tony 107 values are no longer converted to milliseconds from TDateTime and then back again
216     to TDateTime (the conversion to milliseconds is the default TDataset approach).
217 tony 105
218 tony 118 12. Property Editors handling of Stored Procedures.
219 tony 107 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
220     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
221     query).
222     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
223 tony 106
224 tony 118 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
225 tony 107 can be used to select a package. If non-empty, the stored procedure name is
226     expected to be a stored procedure defined in the specified package and the
227     generated SQL will be as required for a stored procedure located in a package.
229 tony 118 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
230 tony 107 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
231     which a stored procedure can be selected. With no package name selected, non-package
232     stored procedures are listed.
234 tony 118 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
235 tony 109 for password on reconnect.
236 tony 107
237 tony 143 16. TIBDatabase: use IAttachment for connection default character set id, code page
238 tony 118 and character set name.
239 tony 109
240 tony 118 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
241     DB info lookups"
243 tony 143 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
244 tony 118
245 tony 127 19. Add a property Editor for TIBUpdate.RefreshSQL.
246 tony 118
247 tony 139 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
248     parameters. This stops an exception being raised when the field cannot be
249     located in the record buffer.
250 tony 127
251 tony 141 21. Property Editors now automatically include System Tables when opened and when the query table
252     is a System Table.
253 tony 139
254 tony 150 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
255 tony 143 This avoids errors due to a stale SQRB or SRB being used for the next query.
256 tony 141
257 tony 143 23. IBServices: Service attach parameters now include "expected_db". This is used to
258     add the SPB item isc_spb_expected_db. This names a database using
259     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
260     database. examples/services re-written to illustrate use of "expected_db".
261 tony 141
262 tony 143 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
263     This avoids truncated backups when the server returns a timeout (busy) response.
265     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
267     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
268     databasenames. These are respectively expanded to the local system's temp directory
269 tony 150 (including trailing delimiter) or to a prescribed data directory (including
270 tony 143 trailing delimiter). Under Unix systems the data directory is a hidden directory
271     in the user's home directory. The hidden directory name is either the string returned
272     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
273     Under Windows, the directory is the same as the Data Directory as decribed
274     above but instead prefixed by the User's application data path. These may be
275 tony 150 used to improve application portability for Personal Databases.
276 tony 143
277     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
278     this has not worked for a long time and is not useful either. FieldDefs should be
279     managed using the Fields Editor as with any other dataset. To access the fields
280     editor for a TIBTable component, double click on the component. The fields editor
281     is then displayed.
283     28. TIBDatabaseInfo: new properties/function
284     * DateDBCreated (returns date/time database created)
285     * TransactionCount (returns no. of active transactions)
286     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
287     * PagesFree (Firebird 3 or later)
288     * PagesUsed (Firebird 3 or later)
289     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
290     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
292     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
294     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
296     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
297     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
299     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
300     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
301     firing during backup and restore.
303     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
304     for verbose output using the new property "StatisticsRequested".
305     see
307     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
309     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
310     palette. This uses the online validation feature added in Firebird 2.5. The
311     services's properties enable inclusion/exclusion of tables and indexes using
312     regular expressions. See.
315     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
316     option on a database.
318     37. TIBCustomService: Assign method implemented to allow copying of service login
319     context between service API components. "Detach" method now only detaches
320     service when last reference to the service interface detaches. Tidy up of
321     code for SetActive and Attach methods including password hiding.
323 tony 150 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
324 tony 143 and used to determine the auth method and protocol used for the connection.
326     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
327     a Create Database Statement generated by IBX.
329     40. All IBServices now have an additional published property "PortNo". This may
330     be set to a non-standard port number when necessary. If zero then the default
331     port number is used.
333     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
334     and not just the mouse.
336     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
338     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
339     image index and selected image index for each node to be set from a database field.
341     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
342     then database schema includes grants to all users. If not present then the
343     only user grants included are those to User PUBLIC.
345     45. TIBTreeView: performance improvement. When expanding include both expanded node
346     and child nodes in dataset.
349 tony 90 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
350 tony 56
351     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
352     changes.
354 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
355     Bug could result in truncated multi-byte character set values.
357 tony 60 3. Changes consequential on moving fbintf character set utility functions from
358     IFirebirdAPI to IAttachment.
360 tony 62 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
362 tony 64 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
363     results in autocomplete ignoring prefix text.
365 tony 65 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
366     entering a new name into the text box.
368 tony 66 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
369     Firebird rather than recomputing it.
371 tony 67 8. Property Editor positioning tidy up: All IBX Property editors should now be
372     screen centre. Previously some were "poDesigned" which may be inappropriate
373     for multi monitor desktops.
375 tony 80 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
377     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
378     a transaction and always reset the object.
380     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
382     13. TIBXScript: Allow for override of database filename in Create Database statements.
384     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
385     to a gbak format archive.
387     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
389     16. IBLocaldb: Drop database if error creating an empty database.
391     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
392     unless selected node not in current dataset.
394     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
395     to TIBCustomService, and IBlocalDB code tidy up.
397     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
398     behaviour due to uninitialised variable.
400     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
401     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
403     21. IBSQL: When Database changed ensure that all resources are freed.
405     22. IBCustomDataset: When database changed ensure that queries an unprepared.
407 tony 84 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
408     * Line Wrap on SQL Token boundaries (on user command)
409     * auto-complete table names in drop down list of table names
410     * Double click on tablename or field name adds to SQL text
411 tony 80
412     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
414     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
415     TVariantArray. Seems to avoid memory corruption in Windows (probably a
416     workaround for a problem in fpc 3.0.4 win64).
418     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
420 tony 83 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
422 tony 51 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
423 tony 49
424 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
425 tony 49 include remote system name.
427     2. TIBExtract: No longer include comment header and COMMIT statement for empty
428     tables when data included in output.
430     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
431     and timing information to be written to stdout. This may be used to locate
432     performance bottlenecks.
434     4. SQLParser: only call "OnChanging" event handler when value is different.
436     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
438 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
439     that BindFields is called when the query is next activated. Avoids FieldName
440     not found error.
442 tony 80 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
443     purpose and allows the programmer to define any action they want for Update, Insert
444     or Delete. This may be complex SQL (similar to a Trigger), application specific
445     filtering of updates, or use of statements such as Grant or Revoke instead of
446     normal DML. See User Manual for more information.
448 tony 47 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
449 tony 45
450 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
451 tony 45
452 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
454     3. TIBExtract: data formatted as Charset set "octets" is now output using
455     hexadecimal notation.
457     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
458     using a simple XML format.
460     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
461     grants to these objects.
463     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
464     dependency problems restoring complex databases.
466     7. TIBXScript: This component has been restructured to allow for the processing of
467     embedded XML in INSERT statements and to support interactive sources in addition
468     to non-interactive data sources such as files.
470     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
472     9. TIBXScript: ISQL compatiable Set statements are now supported:
474     SET TERM
476     SET BAIL
477     SET ECHO
478     SET COUNT
479     SET STATS
480     SET NAMES <character set>
482     10. IBVersion unit added to hold current IBX Version Number information.
484     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
485     and domain definitions.
487     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
488     fully supported.
490     13. TIBExtract: when a database dump includes data, the generator values are now also set.
492     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
494     IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
496 tony 50 See also doc/IBX4LazarusGuide.pdf for important information on
497 tony 45 upgrading to IBX2.
499     1. Size property of TIBStringField is now the width in characters of the field
500     and not the byte length. This applies only to multi-byte character sets such
501     as UTF8. The original approach aligned with TStringField. However, the TStringField
502     code is not recognised as a bug and hence this change to align the behaviour.
503     The TStringField change is expected in fpc 3.2.0.
505     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
506     true (default) then Size property value saved in the lfm is ignored. Size is
507     always set from the dynamic information read from the database. It is unclear
508     why anyone would want to override this and set Size to false.
510     3. ibxscript: should now handle correctly a Case..End statement within a procedure
511     block.
513     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
514     exist when an attempt is made to connect to it (run time only) then an attempt
515     is made to create the database.
517     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
518     has been successfully created as a result of a call to CreateDatabase or when
519     creating a database after it was found not to exist.
521     6. DBControlGrid: a race condition could result in the wrong row image being
522     written to the cache. This has been avoided by a trip round the message
523     loop before rendering the row image.
525     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
526     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
527     known to risk corrupt rendering of row images when the control is first
528     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
529     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
531     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
532     a TDateEdit control located on an editor panel.
534     9. TIBExtract: brought up-to-date plus many bug fixes.
536     10. DBControlGrid: Removed memory leak when updating rows.
538     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
540 tony 43 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
542     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
543     when target codepage is CP_NONE. This is a workaround for
546     2. DBLog option removed from TIBStatisticalService - not supported by server
547     since Firebird 1.5.
549     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
550     similar.
552     4. IBCodePage: updated mapping between codepages and character id.
554     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
555     Firebird. Character sets with a char width of two are not UTF16.
557     6. Strings received from the database are now always transliterated into UTF8
558     regardless of the database character set or connection character set. This
559     is for compatibility with the LCL.

562 tony 41
563     1. IBBlob: Defer reading of blob until read method called. This avoids having to
564     read in an entire blob just to get the size of the blob. General performance
565     improvement when opening datasets containing blobs.
567     2. Clearing a Blob now sets the corresponding field's modified flag.
569     3. IBLookupCombo: When not performing auto-complete, original query sort order
570     is now used.
572     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
573     determined.
575     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
577     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
578     lazarus 1.6.0
580     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
581     compilation error.
583 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
585     1. No character set specified for connection: when a text blob is retrieved, the
586     character set is determined by looking up the native character set using then
587     Firebird API. Otherwise a text mode blob is assumed to have the same character
588     set as the connection.
590     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
591     for Login Dialog returing a change to the database path.
593     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
594     to be changed from that given in the TIBDatabase/TIBServer component and for the
595     entered value to be saved on a project specific basis (design time only).
597     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
598     column fieldname. If they are the same then it is acts as a look up for the KeyValue
599     Otherwise, it sets the column text to the selected ListField Value.
601     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
602     column width.
604     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
605     and a case insensitive search is requested.
607     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
608     or column ListSource.
610     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
611     unprepare) when closing and the text has not changed.
613     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
614     Less likely to cause a cursor re-use error on Windows.
616     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
617     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
619     11. TIBTreeView: Guard against nil destination on record changed
621     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
622     string type with the code page set to reflect the returned field encoding after
623     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
624     earlier versions.
626     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
627     will now result in transliteration to the code page specified for the Firebird driver
628     if the assigned string has a different code page. FPC 3.0.0 onwards only.
630     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
631     is ignored and the lc_ctype value, when the database is opened, is set to align with
632     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
633     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
634     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
635     the GETACP is used to determine the Windows code page.
637     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
638     name used as the lc_ctype when the database was opened. Only valid while the
639     Database is connected.
641     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
642     id that corresponds to the DefaultCharSetName.
644 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
646     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
647     path is given and database attach fails due to access permission issues on the
648     temp directory or security database, then the attach is retried with "localhost:"
649     prefixing the databasename. This should avoid problems when the database has to
650     be accessed by a local (e.g. classic) server and libfbembed is used.
652     2. Windows: revised search order for Firebird DLL:
653     i. The Firebird Embedded Server in the application Directory.
654     ii. If the FIREBIRD environment variable is set then the directory this
655     points to is searched for the FB Client DLL and then then underlying
656     "bin" directory.
657     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
658     is used to locate the Firebird installation directory and the underlying
659     "bin" directory is searched for the FB Client DLL.
660     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
661     are searched for the FB Client DLL.
662     v. The PATH Environment variable is used to search for the FB Client DLL.
663     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
665     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
666     See doc/readme.scriptengine and example applications.
668     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
669     simplify the use of the embedded firebird server on both Linux and Windows platforms.
670     See dpc/readme.localdatabase and example applications.
672     5. IBDynamicGrid: Reordering on column header click should now also work for
673     dynamic columns.
675     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
676     between incrementing/decrementing the lock count and signalling the event.
678 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
680 tony 37 1.3.2 was never formally released and only made available as beta copies.
682 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
684     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
686     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
688     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
689     i.e. when it is a calculated field
691     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
692     This problem was due to a race condition between recalculating row heights and
693     determining which row was selected by the mouse click. The row height calculation
694     is now deferred by an extra trip round the message loop allowing the row to
695     be always calculated on the current grid layout rather than risking it being
696     calculated on the grid layout after the expanded row has been shrunk.
698     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
699     Windows.
701     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
702     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
703 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
704 tony 35
705     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
706 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
707 tony 35
708     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
709     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
710 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
711 tony 35
712     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
713     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
714     implies no truncation.
716     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
718     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
719     (avoids "Not in Edit Mode" error).
721     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
723     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
724     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
726     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
728     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
730     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
732     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
734 tony 33 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
735 tony 31
736     1. OnCloseUp Event Handler added to TDBLookupProperties
738     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
739     problem with row size when exception is called.
741     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
743     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
744     in a TCustomComboBox and ignores return key if in a TCustomMemo
746     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
747     keyed in i.e. when autocomplete not performed
749 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
750     console mode applications with all LCL required functions (builtin dialogs and
751     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
752     not included in your project, IBX should compile and link with a console mode program.
753     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
754     console mode application or the IDE will automatically assume that your
755     application is GUI based. Instead, you should include the ibexpressconsolemode package.
756 tony 31
757     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
758     to use the built in dialogs and cursor management. IBDialogs is
759 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
760 tony 31 This should be the case for all projects created through the IDE. This is why
761     you do not want to add the ibexpress package to console mode applications. The
762     ibexpressconsolemode package has been created to allow console mode programs
763     to avoid adding LCL dependencies when using IBX, while still having the
764     unit search paths set up correctly.
766 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
767     each project's source file (*.lpr).
769 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
770     exists, you have to first open the package in the IDE and then close it. This
771     adds it to the most recently accessed packages list. To make it permanently
772     available, add the package name to lazarus' file.
774 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
775 tony 31
776     7. SQL Parser can now accept quoted strings that include new lines
778     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
779     of text on start of edit. This is particularly useful when tabbing to a
780     column and then inserting text.
782     9. New Examples provided for IB Services and ISQLMonitor.
784     10. Fix error when writing to blob streams that recorded only the last buffer
785     write in the blob stream. In most cases, this did not cause a problem as the
786     IB Blob Stream is written in a single write. However, with the TDBImage, write
787     of a graphic type prefix was lost which caused a problem when the image could
788     not be automatically recognised.
790     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
791 tony 33 already open" errors due to random numbers used for the cursor name being identical.
792 tony 31
793     12. IBTable: corrected error that could result in an "Index out of bounds" error
794     when opening the table and the Primary Key is the last or only column in the
795     table. Thanks to Rick Hoover for the fix.
797 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
798     of "UTF-8", and update list of available database character sets. Existing
799     users should check the current lc_ctype setting in their applications.

801 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
803 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
804     empty Params property.
806     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
807     Link now set up in Loaded method - avoids occasional failure to apply
808     SQL markup on initial open.
810     3. "Employees" example performance improvements when scrolling.
812     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
813     TFrame. Force recaching of selected frame to avoid GTK race (results in a
814     random image cached).
816     5. DBControlGrid: Should now react to changes in panel height at run time.
818     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
819     even when further rows exist.
821     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
822     always be derived from panel height and setting this property can cause confusion.
823     Note for existing projects: to avoid a missing property error at run time,
824     each form using the DBControlGrid must be opened, updated and saved in the IDE
825     in order to remove the property value from the lfm.
828 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
829 tony 27
830     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
831     call Prepare before setting parameter values.
833     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
835     3. Code tidyup and more robust handling of dsql information result vector.
837     4. Support for centralised handling of transaction status changes. TIBTransaction
838     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
839     and "AfterExecQuery". The first three are called after the same event is called
840     for an IBCustomDataSet descendent using the Transaction. The fourth is called
841     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
842     enable monitoring of transaction status changes for a given transaction to be
843     handled in a single place. For example, when a change to the dataset occurs
844     an indicator can be set that shows the user that in order to save changes,
845     the transaction should be committed. Rather than doing this per dataset, this
846     can now be done per transaction.
848     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
849     the dataset is scrolled. However, any changes to the current row are, by default,
850     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
851     have a new property "DataSetCloseAction" that adds automatic posting of changes
852     on dataset close. If this property is set to dcDiscardChanges (default) then the
853     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
854     then IBX will attempt to post any unsaved changes before the dataset is closed
855     (and after the BeforeClose event handler is called). The exception is when the
856     dataset is being closed as a result of a transaction rollback. In this case,
857     no action is taken and any unsaved changes are discarded. This avoids both
858     unnecessary overhead and the risk that a validation error may occur in the Post
859     raising an exception and thereby preventing a rollback.
861     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
862     In earlier versions, the Display Width was set to the maximum byte width rather than the character
863     width. Display Widths are now corrected by dividing by the max byte width per character.
864     For UTF8 character sets, the byte width is four and hence the Display Width will be
865     the byte width divided by 4. The byte width of each character set is determined
866     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
867     system table. (see also
869     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
871     8. IBLookupComboEditBox: List should now always be restored to full list when the
872     control loses focus. Default Key press default interval reduced to 200ms.
874     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
875     when dataset rows are less than visible rows.
877     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
878     does not exist or DataSet is empty. More responsive on dataset open. New event
879     OnRestorePosition. Column sort disabled if no header row.
881     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
882     while dataset state is dsInsert. Avoids posting errors.
884     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
885     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
887     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
889     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
890     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
891     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
892     always "posts" the current record regardless or whether or not it may be more appropriate
893     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
894     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
895     as the first action of the "Post" method and allows the handler to convert the Post
896     into a Cancel if that is the appropriate action on moving to a different row. This is
897     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
898     raised here, but it may still be more appropriate to validate a post and signal
899     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
901     15. On Unix derived systems, the Firebird library name can now be given as a colon
902     separated list. Each library name on the list is tried in turn, in left to right
903     order with the first found being used as the firebird library. By default, on Linux,
904     the library name list is ''. This can be
905     overidden by the FBLIB environment variable or the OnGetLibraryName function.
907     Note: when using the, if you prefix the database name with "localhost:"
908     then it will still attempt to access the database via the Firebird Server and will
909     require a username and password. If only the pathname is given, then the username
910     and password should be omitted and the unix file permissions are used to grant
911     access.

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

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

1000 tony 19
1001     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1002     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1003     Gabor Boros for reporting this problem and for testing the improvements).
1005     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1006     See readme.field+param.names in the doc folder.
1008     3. IBX SQL Editors will now automatically add double quotes around column names when the database
1009     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1011     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1013     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1014     actions.
1016     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1017     thanks to Yuriy Kopnin for pointing this out).
1019     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1021     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1022     for both fields and parameter setting.
1024     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1025     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1027     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1028     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1030     11. TIBTable now has a property editor for "MasterFields"
1032     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1033     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1035     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1036     of settings is unrecognised. Selecting this radio button has no effect on the settings.

1041     1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1043 tony 15 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1045     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1046     it is null. This allows for alternative user defined setting of the generator
1048     Many thanks to Julio Jiménez for this fix
1050     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1051     and suggests that the user may have forgotten to install it.
1053 tony 13 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1055     1. Conditional compilation used to limit registration of TIntegerField to
1056     Lazarus versions less than 1.1
1058     2. When a database connection is created, character set is now by default set
1059     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1060     1250 to 1254.
1063 tony 11 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1065     1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1068 tony 9 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1069 tony 7
1070     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1071     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1073     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1074     package is changed to do this (which it should do).
1076     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1078     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1080     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1082     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1084     4. Property editors should now correctly resize.
1086     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1087     (restored original functionality)
1089     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1090     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
