1 tony 209 IBX Change Log version (2.3-0) Wed, 14 Mar 2018 12:29:06 +0000
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.
5    
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.
12    
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.
20    
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.
25    
26     3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
27     updated to use the new Services API components.
28    
29     4. The iblocal package has been updated to use the new Services API components.
30    
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.
36    
37     6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
38     are ignored.
39    
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.
43    
44     8. TIBTransaction: OnStartTransaction event now fires every time the transaction
45     is started and not just the first time.
46    
47     9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
48     depenendency with comp type.
49    
50     10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
51    
52     11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
53     then this is recognised and not ignored.
54    
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;
59    
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.
65    
66     See ibx/examples/consolemode for an example of the use of GetPerfStatistics
67    
68     13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
69     in parenthesises.
70    
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.
75    
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.
78    
79     16. TIBDataSet, TIBQuery, TIBTable: addition:
80     property MasterDetailDelay: integer {defaults to zero}
81    
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.
88    
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.
95    
96     18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
97     When a deLaoutChanged event is reported on the ListSource dataset, the
98     combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
99     relationship with the control's datasource (master).
100    
101     IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
102    
103 tony 151 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
104 tony 152 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
105 tony 151 RELEASE.
106    
107     NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
108    
109 tony 107 1. IBExtract: Identity columns - add additional check for null column for generator name.
110 tony 101
111     2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
112     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
113 tony 107 information). However, this is also a very useful mechanism for returning updated computed by
114     column values. Values returned as a result of executing an Insert or Update statement
115     replace existing values in the current row for each corresponding column.
116 tony 101
117 tony 107 Previously, if a dataset's select query included read only (computed by) fields then
118     an automatic row refresh was performed after an insert or update query had been processed,
119     irrespective of the setting of the "ForcedUpdates" property. This has changed such
120     that an automatic refresh is no longer performed if an insert or update query contains
121     a returning clause that updates one or more fields on the current row. A full row
122     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
123     field values and the select query contains read only fields. Use of Insert/update
124 tony 123 returning should be significantly more efficient than executing a refresh query.
125 tony 107
126     This behaviour change is intended to be backwards compatible and there should be no need to change
127     existing programs, other than to improve performance by using the new capability.
128    
129 tony 118 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
130     they are called when the dataset row is being deleted, there is no value in
131     updating the current record from the query result. Instead, a new event handler
132     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
133     an OnDeleteReturning event handler is provided then it is called with the IResults returned
134     by the query. The event handler can then interrogate the query results and
135     perform whatever action is necessary. For example to confirm, to the user,
136     the deletion of a row with the returned values.
137    
138     4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
139 tony 107 any Computed By or Identity Columns. The IBTables example has been updated to
140     illustrate the computation of the employee Full Name on update.
141    
142 tony 118 5. TIBTable: The GeneratorField property is now published.
143 tony 107
144 tony 118 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
145 tony 101 When InsertSQL is generated, the Identity columns are not included in the list of values to
146     be inserted. A RETURNING clause is added to the insert statement to return the value of
147     each Identity column after the insert is executed.
148    
149 tony 118 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
150 tony 107 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
151     Insert..Returning clause.
152 tony 104
153 tony 118 8. TIBGenerator: small performance improvement by not preparing query each time
154 tony 107 a new value is generated.
155 tony 104
156 tony 118 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
157 tony 107
158 tony 118 10. Property editors will now sync table name to a System Table when "Include System
159     Tables" is selected and the query is for a System Table.
160 tony 105
161 tony 118 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
162 tony 107 values are no longer converted to milliseconds from TDateTime and then back again
163     to TDateTime (the conversion to milliseconds is the default TDataset approach).
164 tony 105
165 tony 118 12. Property Editors handling of Stored Procedures.
166 tony 107 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
167     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
168     query).
169     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
170 tony 106
171 tony 118 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
172 tony 107 can be used to select a package. If non-empty, the stored procedure name is
173     expected to be a stored procedure defined in the specified package and the
174     generated SQL will be as required for a stored procedure located in a package.
175    
176 tony 118 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
177 tony 107 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
178     which a stored procedure can be selected. With no package name selected, non-package
179     stored procedures are listed.
180    
181 tony 118 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
182 tony 109 for password on reconnect.
183 tony 107
184 tony 143 16. TIBDatabase: use IAttachment for connection default character set id, code page
185 tony 118 and character set name.
186 tony 109
187 tony 118 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
188     DB info lookups"
189    
190 tony 143 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
191 tony 118
192 tony 127 19. Add a property Editor for TIBUpdate.RefreshSQL.
193 tony 118
194 tony 139 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
195     parameters. This stops an exception being raised when the field cannot be
196     located in the record buffer.
197 tony 127
198 tony 141 21. Property Editors now automatically include System Tables when opened and when the query table
199     is a System Table.
200 tony 139
201 tony 150 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
202 tony 143 This avoids errors due to a stale SQRB or SRB being used for the next query.
203 tony 141
204 tony 143 23. IBServices: Service attach parameters now include "expected_db". This is used to
205     add the SPB item isc_spb_expected_db. This names a database using
206     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
207     database. examples/services re-written to illustrate use of "expected_db".
208 tony 141
209 tony 143 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
210     This avoids truncated backups when the server returns a timeout (busy) response.
211    
212     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
213    
214     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
215     databasenames. These are respectively expanded to the local system's temp directory
216 tony 150 (including trailing delimiter) or to a prescribed data directory (including
217 tony 143 trailing delimiter). Under Unix systems the data directory is a hidden directory
218     in the user's home directory. The hidden directory name is either the string returned
219     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
220     Under Windows, the directory is the same as the Data Directory as decribed
221     above but instead prefixed by the User's application data path. These may be
222 tony 150 used to improve application portability for Personal Databases.
223 tony 143
224     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
225     this has not worked for a long time and is not useful either. FieldDefs should be
226     managed using the Fields Editor as with any other dataset. To access the fields
227     editor for a TIBTable component, double click on the component. The fields editor
228     is then displayed.
229    
230     28. TIBDatabaseInfo: new properties/function
231     * DateDBCreated (returns date/time database created)
232     * TransactionCount (returns no. of active transactions)
233     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
234     * PagesFree (Firebird 3 or later)
235     * PagesUsed (Firebird 3 or later)
236     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
237     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
238    
239     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
240    
241     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
242    
243     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
244     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
245    
246     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
247     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
248     firing during backup and restore.
249    
250     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
251     for verbose output using the new property "StatisticsRequested".
252     see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
253    
254     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
255    
256     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
257     palette. This uses the online validation feature added in Firebird 2.5. The
258     services's properties enable inclusion/exclusion of tables and indexes using
259     regular expressions. See.
260     https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
261    
262     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
263     option on a database.
264    
265     37. TIBCustomService: Assign method implemented to allow copying of service login
266     context between service API components. "Detach" method now only detaches
267     service when last reference to the service interface detaches. Tidy up of
268     code for SetActive and Attach methods including password hiding.
269    
270 tony 150 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
271 tony 143 and used to determine the auth method and protocol used for the connection.
272    
273     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
274     a Create Database Statement generated by IBX.
275    
276     40. All IBServices now have an additional published property "PortNo". This may
277     be set to a non-standard port number when necessary. If zero then the default
278     port number is used.
279    
280     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
281     and not just the mouse.
282    
283     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
284    
285     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
286     image index and selected image index for each node to be set from a database field.
287    
288     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
289     then database schema includes grants to all users. If not present then the
290     only user grants included are those to User PUBLIC.
291    
292     45. TIBTreeView: performance improvement. When expanding include both expanded node
293     and child nodes in dataset.
294    
295    
296 tony 90 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
297 tony 56
298     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
299     changes.
300    
301 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
302     Bug could result in truncated multi-byte character set values.
303    
304 tony 60 3. Changes consequential on moving fbintf character set utility functions from
305     IFirebirdAPI to IAttachment.
306    
307 tony 62 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
308    
309 tony 64 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
310     results in autocomplete ignoring prefix text.
311    
312 tony 65 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
313     entering a new name into the text box.
314    
315 tony 66 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
316     Firebird rather than recomputing it.
317    
318 tony 67 8. Property Editor positioning tidy up: All IBX Property editors should now be
319     screen centre. Previously some were "poDesigned" which may be inappropriate
320     for multi monitor desktops.
321    
322 tony 80 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
323    
324     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
325     a transaction and always reset the object.
326    
327     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
328    
329     13. TIBXScript: Allow for override of database filename in Create Database statements.
330    
331     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
332     to a gbak format archive.
333    
334     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
335    
336     16. IBLocaldb: Drop database if error creating an empty database.
337    
338     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
339     unless selected node not in current dataset.
340    
341     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
342     to TIBCustomService, and IBlocalDB code tidy up.
343    
344     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
345     behaviour due to uninitialised variable.
346    
347     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
348     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
349    
350     21. IBSQL: When Database changed ensure that all resources are freed.
351    
352     22. IBCustomDataset: When database changed ensure that queries an unprepared.
353    
354 tony 84 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
355     * Line Wrap on SQL Token boundaries (on user command)
356     * auto-complete table names in drop down list of table names
357     * Double click on tablename or field name adds to SQL text
358 tony 80
359     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
360    
361     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
362     TVariantArray. Seems to avoid memory corruption in Windows (probably a
363     workaround for a problem in fpc 3.0.4 win64).
364    
365     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
366    
367 tony 83 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
368    
369 tony 51 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
370 tony 49
371 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
372 tony 49 include remote system name.
373    
374     2. TIBExtract: No longer include comment header and COMMIT statement for empty
375     tables when data included in output.
376    
377     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
378     and timing information to be written to stdout. This may be used to locate
379     performance bottlenecks.
380    
381     4. SQLParser: only call "OnChanging" event handler when value is different.
382    
383     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
384    
385 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
386     that BindFields is called when the query is next activated. Avoids FieldName
387     not found error.
388    
389 tony 80 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
390     purpose and allows the programmer to define any action they want for Update, Insert
391     or Delete. This may be complex SQL (similar to a Trigger), application specific
392     filtering of updates, or use of statements such as Grant or Revoke instead of
393     normal DML. See User Manual for more information.
394    
395 tony 47 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
396 tony 45
397 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
398 tony 45
399 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
400    
401     3. TIBExtract: data formatted as Charset set "octets" is now output using
402     hexadecimal notation.
403    
404     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
405     using a simple XML format.
406    
407     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
408     grants to these objects.
409    
410     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
411     dependency problems restoring complex databases.
412    
413     7. TIBXScript: This component has been restructured to allow for the processing of
414     embedded XML in INSERT statements and to support interactive sources in addition
415     to non-interactive data sources such as files.
416    
417     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
418    
419     9. TIBXScript: ISQL compatiable Set statements are now supported:
420     SET SQL DIALECT
421     SET TERM
422     SET AUTODDL
423     SET BAIL
424     SET ECHO
425     SET COUNT
426     SET STATS
427     SET NAMES <character set>
428    
429     10. IBVersion unit added to hold current IBX Version Number information.
430    
431     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
432     and domain definitions.
433    
434     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
435     fully supported.
436    
437     13. TIBExtract: when a database dump includes data, the generator values are now also set.
438    
439     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.

442    
443 tony 50 See also doc/IBX4LazarusGuide.pdf for important information on
444 tony 45 upgrading to IBX2.
445    
446     1. Size property of TIBStringField is now the width in characters of the field
447     and not the byte length. This applies only to multi-byte character sets such
448     as UTF8. The original approach aligned with TStringField. However, the TStringField
449     code is not recognised as a bug and hence this change to align the behaviour.
450     The TStringField change is expected in fpc 3.2.0.
451    
452     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
453     true (default) then Size property value saved in the lfm is ignored. Size is
454     always set from the dynamic information read from the database. It is unclear
455     why anyone would want to override this and set Size to false.
456    
457     3. ibxscript: should now handle correctly a Case..End statement within a procedure
458     block.
459    
460     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
461     exist when an attempt is made to connect to it (run time only) then an attempt
462     is made to create the database.
463    
464     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
465     has been successfully created as a result of a call to CreateDatabase or when
466     creating a database after it was found not to exist.
467    
468     6. DBControlGrid: a race condition could result in the wrong row image being
469     written to the cache. This has been avoided by a trip round the message
470     loop before rendering the row image.
471    
472     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
473     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
474     known to risk corrupt rendering of row images when the control is first
475     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
476     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
477    
478     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
479     a TDateEdit control located on an editor panel.
480    
481     9. TIBExtract: brought up-to-date plus many bug fixes.
482    
483     10. DBControlGrid: Removed memory leak when updating rows.
484    
485     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

488    
489     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
490     when target codepage is CP_NONE. This is a workaround for
491     http://bugs.freepascal.org/view.php?id=30622.
492    
493     2. DBLog option removed from TIBStatisticalService - not supported by server
494     since Firebird 1.5.
495    
496     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
497     similar.
498    
499     4. IBCodePage: updated mapping between codepages and character id.
500    
501     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
502     Firebird. Character sets with a char width of two are not UTF16.
503    
504     6. Strings received from the database are now always transliterated into UTF8
505     regardless of the database character set or connection character set. This
506     is for compatibility with the LCL.
507    
508 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
509 tony 41
510     1. IBBlob: Defer reading of blob until read method called. This avoids having to
511     read in an entire blob just to get the size of the blob. General performance
512     improvement when opening datasets containing blobs.
513    
514     2. Clearing a Blob now sets the corresponding field's modified flag.
515    
516     3. IBLookupCombo: When not performing auto-complete, original query sort order
517     is now used.
518    
519     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
520     determined.
521    
522     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
523    
524     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
525     lazarus 1.6.0
526    
527     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
528     compilation error.
529    
530 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
531    
532     1. No character set specified for connection: when a text blob is retrieved, the
533     character set is determined by looking up the native character set using then
534     Firebird API. Otherwise a text mode blob is assumed to have the same character
535     set as the connection.
536    
537     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
538     for Login Dialog returing a change to the database path.
539    
540     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
541     to be changed from that given in the TIBDatabase/TIBServer component and for the
542     entered value to be saved on a project specific basis (design time only).
543    
544     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
545     column fieldname. If they are the same then it is acts as a look up for the KeyValue
546     Otherwise, it sets the column text to the selected ListField Value.
547    
548     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
549     column width.
550    
551     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
552     and a case insensitive search is requested.
553    
554     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
555     or column ListSource.
556    
557     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
558     unprepare) when closing and the text has not changed.
559    
560     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
561     Less likely to cause a cursor re-use error on Windows.
562    
563     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
564     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
565    
566     11. TIBTreeView: Guard against nil destination on record changed
567    
568     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
569     string type with the code page set to reflect the returned field encoding after
570     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
571     earlier versions.
572    
573     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
574     will now result in transliteration to the code page specified for the Firebird driver
575     if the assigned string has a different code page. FPC 3.0.0 onwards only.
576    
577     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
578     is ignored and the lc_ctype value, when the database is opened, is set to align with
579     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
580     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
581     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
582     the GETACP is used to determine the Windows code page.
583    
584     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
585     name used as the lc_ctype when the database was opened. Only valid while the
586     Database is connected.
587    
588     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
589     id that corresponds to the DefaultCharSetName.
590    
591 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
592    
593     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
594     path is given and database attach fails due to access permission issues on the
595     temp directory or security database, then the attach is retried with "localhost:"
596     prefixing the databasename. This should avoid problems when the database has to
597     be accessed by a local (e.g. classic) server and libfbembed is used.
598    
599     2. Windows: revised search order for Firebird DLL:
600     i. The Firebird Embedded Server in the application Directory.
601     ii. If the FIREBIRD environment variable is set then the directory this
602     points to is searched for the FB Client DLL and then then underlying
603     "bin" directory.
604     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
605     is used to locate the Firebird installation directory and the underlying
606     "bin" directory is searched for the FB Client DLL.
607     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
608     are searched for the FB Client DLL.
609     v. The PATH Environment variable is used to search for the FB Client DLL.
610     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
611    
612     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
613     See doc/readme.scriptengine and example applications.
614    
615     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
616     simplify the use of the embedded firebird server on both Linux and Windows platforms.
617     See dpc/readme.localdatabase and example applications.
618    
619     5. IBDynamicGrid: Reordering on column header click should now also work for
620     dynamic columns.
621    
622     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
623     between incrementing/decrementing the lock count and signalling the event.
624    
625 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
626    
627 tony 37 1.3.2 was never formally released and only made available as beta copies.
628    
629 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
630    
631     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
632    
633     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
634    
635     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
636     i.e. when it is a calculated field
637    
638     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
639     This problem was due to a race condition between recalculating row heights and
640     determining which row was selected by the mouse click. The row height calculation
641     is now deferred by an extra trip round the message loop allowing the row to
642     be always calculated on the current grid layout rather than risking it being
643     calculated on the grid layout after the expanded row has been shrunk.
644    
645     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
646     Windows.
647    
648     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
649     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
650 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
651 tony 35
652     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
653 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
654 tony 35
655     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
656     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
657 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
658 tony 35
659     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
660     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
661     implies no truncation.
662    
663     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
664    
665     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
666     (avoids "Not in Edit Mode" error).
667    
668     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
669    
670     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
671     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
672    
673     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
674    
675     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
676    
677     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
678    
679     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
680    
681 tony 33 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
682 tony 31
683     1. OnCloseUp Event Handler added to TDBLookupProperties
684    
685     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
686     problem with row size when exception is called.
687    
688     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
689    
690     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
691     in a TCustomComboBox and ignores return key if in a TCustomMemo
692    
693     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
694     keyed in i.e. when autocomplete not performed
695    
696 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
697     console mode applications with all LCL required functions (builtin dialogs and
698     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
699     not included in your project, IBX should compile and link with a console mode program.
700     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
701     console mode application or the IDE will automatically assume that your
702     application is GUI based. Instead, you should include the ibexpressconsolemode package.
703 tony 31
704     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
705     to use the built in dialogs and cursor management. IBDialogs is
706 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
707 tony 31 This should be the case for all projects created through the IDE. This is why
708     you do not want to add the ibexpress package to console mode applications. The
709     ibexpressconsolemode package has been created to allow console mode programs
710     to avoid adding LCL dependencies when using IBX, while still having the
711     unit search paths set up correctly.
712    
713 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
714     each project's source file (*.lpr).
715    
716 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
717     exists, you have to first open the package in the IDE and then close it. This
718     adds it to the most recently accessed packages list. To make it permanently
719     available, add the package name to lazarus' staticpackages.inc file.
720    
721 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
722 tony 31
723     7. SQL Parser can now accept quoted strings that include new lines
724    
725     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
726     of text on start of edit. This is particularly useful when tabbing to a
727     column and then inserting text.
728    
729     9. New Examples provided for IB Services and ISQLMonitor.
730    
731     10. Fix error when writing to blob streams that recorded only the last buffer
732     write in the blob stream. In most cases, this did not cause a problem as the
733     IB Blob Stream is written in a single write. However, with the TDBImage, write
734     of a graphic type prefix was lost which caused a problem when the image could
735     not be automatically recognised.
736    
737     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
738 tony 33 already open" errors due to random numbers used for the cursor name being identical.
739 tony 31
740     12. IBTable: corrected error that could result in an "Index out of bounds" error
741     when opening the table and the Primary Key is the last or only column in the
742     table. Thanks to Rick Hoover for the fix.
743    
744 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
745     of "UTF-8", and update list of available database character sets. Existing
746     users should check the current lc_ctype setting in their applications.
747 tony 29
748 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
749    
750 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
751     empty Params property.
752    
753     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
754     Link now set up in Loaded method - avoids occasional failure to apply
755     SQL markup on initial open.
756    
757     3. "Employees" example performance improvements when scrolling.
758    
759     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
760     TFrame. Force recaching of selected frame to avoid GTK race (results in a
761     random image cached).
762    
763     5. DBControlGrid: Should now react to changes in panel height at run time.
764    
765     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
766     even when further rows exist.
767    
768     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
769     always be derived from panel height and setting this property can cause confusion.
770     Note for existing projects: to avoid a missing property error at run time,
771     each form using the DBControlGrid must be opened, updated and saved in the IDE
772     in order to remove the property value from the lfm.
773    
774    
775 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
776 tony 27
777     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
778     call Prepare before setting parameter values.
779    
780     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
781    
782     3. Code tidyup and more robust handling of dsql information result vector.
783    
784     4. Support for centralised handling of transaction status changes. TIBTransaction
785     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
786     and "AfterExecQuery". The first three are called after the same event is called
787     for an IBCustomDataSet descendent using the Transaction. The fourth is called
788     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
789     enable monitoring of transaction status changes for a given transaction to be
790     handled in a single place. For example, when a change to the dataset occurs
791     an indicator can be set that shows the user that in order to save changes,
792     the transaction should be committed. Rather than doing this per dataset, this
793     can now be done per transaction.
794    
795     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
796     the dataset is scrolled. However, any changes to the current row are, by default,
797     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
798     have a new property "DataSetCloseAction" that adds automatic posting of changes
799     on dataset close. If this property is set to dcDiscardChanges (default) then the
800     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
801     then IBX will attempt to post any unsaved changes before the dataset is closed
802     (and after the BeforeClose event handler is called). The exception is when the
803     dataset is being closed as a result of a transaction rollback. In this case,
804     no action is taken and any unsaved changes are discarded. This avoids both
805     unnecessary overhead and the risk that a validation error may occur in the Post
806     raising an exception and thereby preventing a rollback.
807    
808     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
809     In earlier versions, the Display Width was set to the maximum byte width rather than the character
810     width. Display Widths are now corrected by dividing by the max byte width per character.
811     For UTF8 character sets, the byte width is four and hence the Display Width will be
812     the byte width divided by 4. The byte width of each character set is determined
813     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
814     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
815    
816     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
817    
818     8. IBLookupComboEditBox: List should now always be restored to full list when the
819     control loses focus. Default Key press default interval reduced to 200ms.
820    
821     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
822     when dataset rows are less than visible rows.
823    
824     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
825     does not exist or DataSet is empty. More responsive on dataset open. New event
826     OnRestorePosition. Column sort disabled if no header row.
827    
828     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
829     while dataset state is dsInsert. Avoids posting errors.
830    
831     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
832     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
833    
834     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
835    
836     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
837     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
838     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
839     always "posts" the current record regardless or whether or not it may be more appropriate
840     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
841     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
842     as the first action of the "Post" method and allows the handler to convert the Post
843     into a Cancel if that is the appropriate action on moving to a different row. This is
844     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
845     raised here, but it may still be more appropriate to validate a post and signal
846     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
847    
848     15. On Unix derived systems, the Firebird library name can now be given as a colon
849     separated list. Each library name on the list is tried in turn, in left to right
850     order with the first found being used as the firebird library. By default, on Linux,
851     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
852     overidden by the FBLIB environment variable or the OnGetLibraryName function.
853    
854     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
855     then it will still attempt to access the database via the Firebird Server and will
856     require a username and password. If only the pathname is given, then the username
857     and password should be omitted and the unix file permissions are used to grant
858     access.

862     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
863     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
864     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
865 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
866 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
867    
868     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
869 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
870 tony 23 takes place during database access. This may be useful when there are performance issues with
871     the change of cursor. Setting the property to false suppresses the change of cursor.
872    
873     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
874     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
875     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
876     making all changes permanent immediately rather than when the transaction is explicitly
877     committed.
878    
879 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
880 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

887 tony 21
888     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
889     This is typically used during an "OnBeforeOpen" event handler to manipulate the
890     "Where" and "Having" clauses to implement user specified filters of arbitrary
891     complexity.
892    
893     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
894     three new data aware controls dependent on IBX and which make use of the SQL Parser.
895     These are:
896    
897     - TIBLookupComboEditBox
898     - TIBDynamicGrid
899     - TIBTreeview
900    
901     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
902     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
903     to revise the available list and restrict it to items that are prefixed by the
904 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
905 tony 21 newly typed entry to be added to the list dataset and included in the available
906     list items.
907    
908     TIBDynamicGrid is a TDBGrid descendent that provides for:
909     - automatic resizing of selected columns to fill the available row length
910     - automatic positioning and sizing of a "totals" control, typically at the
911     column footer, on a per column basis.
912     - DataSet resorting on header row click, sorting the dataset by the selected column.
913     A second click on the same header cell reversed the sort order.
914     - Support for a "Panel Editor". That is on clicking the indicator column, the row
915     is automatically expanded and a panel superimposed on it. The panel can have any
916     number of child controls, typically data aware controls with the same datasource
917     as the grid allowing for editing of additional fields and more complex editors.
918     - Reselection of the same row following resorting.
919     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
920     Its properties are specified on a per column basis and allows for one or more
921     columns to have their values selected from a list provided by a dataset.
922     Autocomplete and autoinsert are also available. The existing picklist editor
923     is unaffected by the extension.
924    
925     TIBTreeView is a data aware TCustomTreeView.
926    
927     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
928     zero scale will no longer return an error. An Int64 will be returned instead.
929    
930     4. TIBTransaction now has events for Before and After Transaction End and a new function
931     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
932    
933     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
934     repeated multiple times.
935    
936     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
937     check used to get in the way of using Stored Procedures, and "Update or Insert"
938     statements.
939    
940     7. Insert, Modify and Delete property Editors now support Query Generation from
941     Stored Procedures.
942    
943     8. Three new examples illustrate the use of the new IB Controls
944

947 tony 19
948     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
949     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
950     Gabor Boros for reporting this problem and for testing the improvements).
951    
952     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
953     See readme.field+param.names in the doc folder.
954    
955     3. IBX SQL Editors will now automatically add double quotes around column names when the database
956     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
957    
958     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
959    
960     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
961     actions.
962    
963     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
964     thanks to Yuriy Kopnin for pointing this out).
965    
966     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
967    
968     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
969     for both fields and parameter setting.
970    
971     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
972     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
973    
974     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
975     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
976    
977     11. TIBTable now has a property editor for "MasterFields"
978    
979     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
980     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
981    
982     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
983     of settings is unrecognised. Selecting this radio button has no effect on the settings.

992     1. In a TIBCustomDataset descendent, a generator now only sets the value when
993     it is null. This allows for alternative user defined setting of the generator
994    
995     Many thanks to Julio Jiménez for this fix
996    
997     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
998     and suggests that the user may have forgotten to install it.

1002     1. Conditional compilation used to limit registration of TIntegerField to
1003     Lazarus versions less than 1.1
1004    
1005     2. When a database connection is created, character set is now by default set
1006     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1007     1250 to 1254.

1017     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1018     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1019    
1020     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1021     package is changed to do this (which it should do).
1022    
1023     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1024    
1025     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1026    
1027     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1028    
1029     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1030    
1031     4. Property editors should now correctly resize.
1032    
1033     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1034     (restored original functionality)
1035    
1036     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1037     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
