1 tony 226 IBX Change Log version (2.3-0) Tue, 03 Apr 2018 11:48:08 +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.
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 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).
100    
101 tony 221 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
102    
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.
105    
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).
108    
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.
116    
117 tony 226 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
118 tony 225 between SQL statements.
119    
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.
125    
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.
128    
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.
132    
133 tony 209 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
134    
135 tony 151 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
136 tony 152 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
137 tony 151 RELEASE.
138    
139     NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
140    
141 tony 107 1. IBExtract: Identity columns - add additional check for null column for generator name.
142 tony 101
143     2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
144     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
145 tony 107 information). However, this is also a very useful mechanism for returning updated computed by
146     column values. Values returned as a result of executing an Insert or Update statement
147     replace existing values in the current row for each corresponding column.
148 tony 101
149 tony 107 Previously, if a dataset's select query included read only (computed by) fields then
150     an automatic row refresh was performed after an insert or update query had been processed,
151     irrespective of the setting of the "ForcedUpdates" property. This has changed such
152     that an automatic refresh is no longer performed if an insert or update query contains
153     a returning clause that updates one or more fields on the current row. A full row
154     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
155     field values and the select query contains read only fields. Use of Insert/update
156 tony 123 returning should be significantly more efficient than executing a refresh query.
157 tony 107
158     This behaviour change is intended to be backwards compatible and there should be no need to change
159     existing programs, other than to improve performance by using the new capability.
160    
161 tony 118 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
162     they are called when the dataset row is being deleted, there is no value in
163     updating the current record from the query result. Instead, a new event handler
164     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
165     an OnDeleteReturning event handler is provided then it is called with the IResults returned
166     by the query. The event handler can then interrogate the query results and
167     perform whatever action is necessary. For example to confirm, to the user,
168     the deletion of a row with the returned values.
169    
170     4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
171 tony 107 any Computed By or Identity Columns. The IBTables example has been updated to
172     illustrate the computation of the employee Full Name on update.
173    
174 tony 118 5. TIBTable: The GeneratorField property is now published.
175 tony 107
176 tony 118 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
177 tony 101 When InsertSQL is generated, the Identity columns are not included in the list of values to
178     be inserted. A RETURNING clause is added to the insert statement to return the value of
179     each Identity column after the insert is executed.
180    
181 tony 118 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
182 tony 107 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
183     Insert..Returning clause.
184 tony 104
185 tony 118 8. TIBGenerator: small performance improvement by not preparing query each time
186 tony 107 a new value is generated.
187 tony 104
188 tony 118 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
189 tony 107
190 tony 118 10. Property editors will now sync table name to a System Table when "Include System
191     Tables" is selected and the query is for a System Table.
192 tony 105
193 tony 118 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
194 tony 107 values are no longer converted to milliseconds from TDateTime and then back again
195     to TDateTime (the conversion to milliseconds is the default TDataset approach).
196 tony 105
197 tony 118 12. Property Editors handling of Stored Procedures.
198 tony 107 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
199     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
200     query).
201     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
202 tony 106
203 tony 118 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
204 tony 107 can be used to select a package. If non-empty, the stored procedure name is
205     expected to be a stored procedure defined in the specified package and the
206     generated SQL will be as required for a stored procedure located in a package.
207    
208 tony 118 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
209 tony 107 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
210     which a stored procedure can be selected. With no package name selected, non-package
211     stored procedures are listed.
212    
213 tony 118 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
214 tony 109 for password on reconnect.
215 tony 107
216 tony 143 16. TIBDatabase: use IAttachment for connection default character set id, code page
217 tony 118 and character set name.
218 tony 109
219 tony 118 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
220     DB info lookups"
221    
222 tony 143 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
223 tony 118
224 tony 127 19. Add a property Editor for TIBUpdate.RefreshSQL.
225 tony 118
226 tony 139 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
227     parameters. This stops an exception being raised when the field cannot be
228     located in the record buffer.
229 tony 127
230 tony 141 21. Property Editors now automatically include System Tables when opened and when the query table
231     is a System Table.
232 tony 139
233 tony 150 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
234 tony 143 This avoids errors due to a stale SQRB or SRB being used for the next query.
235 tony 141
236 tony 143 23. IBServices: Service attach parameters now include "expected_db". This is used to
237     add the SPB item isc_spb_expected_db. This names a database using
238     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
239     database. examples/services re-written to illustrate use of "expected_db".
240 tony 141
241 tony 143 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
242     This avoids truncated backups when the server returns a timeout (busy) response.
243    
244     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
245    
246     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
247     databasenames. These are respectively expanded to the local system's temp directory
248 tony 150 (including trailing delimiter) or to a prescribed data directory (including
249 tony 143 trailing delimiter). Under Unix systems the data directory is a hidden directory
250     in the user's home directory. The hidden directory name is either the string returned
251     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
252     Under Windows, the directory is the same as the Data Directory as decribed
253     above but instead prefixed by the User's application data path. These may be
254 tony 150 used to improve application portability for Personal Databases.
255 tony 143
256     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
257     this has not worked for a long time and is not useful either. FieldDefs should be
258     managed using the Fields Editor as with any other dataset. To access the fields
259     editor for a TIBTable component, double click on the component. The fields editor
260     is then displayed.
261    
262     28. TIBDatabaseInfo: new properties/function
263     * DateDBCreated (returns date/time database created)
264     * TransactionCount (returns no. of active transactions)
265     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
266     * PagesFree (Firebird 3 or later)
267     * PagesUsed (Firebird 3 or later)
268     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
269     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
270    
271     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
272    
273     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
274    
275     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
276     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
277    
278     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
279     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
280     firing during backup and restore.
281    
282     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
283     for verbose output using the new property "StatisticsRequested".
284     see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
285    
286     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
287    
288     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
289     palette. This uses the online validation feature added in Firebird 2.5. The
290     services's properties enable inclusion/exclusion of tables and indexes using
291     regular expressions. See.
292     https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
293    
294     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
295     option on a database.
296    
297     37. TIBCustomService: Assign method implemented to allow copying of service login
298     context between service API components. "Detach" method now only detaches
299     service when last reference to the service interface detaches. Tidy up of
300     code for SetActive and Attach methods including password hiding.
301    
302 tony 150 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
303 tony 143 and used to determine the auth method and protocol used for the connection.
304    
305     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
306     a Create Database Statement generated by IBX.
307    
308     40. All IBServices now have an additional published property "PortNo". This may
309     be set to a non-standard port number when necessary. If zero then the default
310     port number is used.
311    
312     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
313     and not just the mouse.
314    
315     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
316    
317     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
318     image index and selected image index for each node to be set from a database field.
319    
320     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
321     then database schema includes grants to all users. If not present then the
322     only user grants included are those to User PUBLIC.
323    
324     45. TIBTreeView: performance improvement. When expanding include both expanded node
325     and child nodes in dataset.
326    
327    
328 tony 90 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
329 tony 56
330     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
331     changes.
332    
333 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
334     Bug could result in truncated multi-byte character set values.
335    
336 tony 60 3. Changes consequential on moving fbintf character set utility functions from
337     IFirebirdAPI to IAttachment.
338    
339 tony 62 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
340    
341 tony 64 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
342     results in autocomplete ignoring prefix text.
343    
344 tony 65 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
345     entering a new name into the text box.
346    
347 tony 66 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
348     Firebird rather than recomputing it.
349    
350 tony 67 8. Property Editor positioning tidy up: All IBX Property editors should now be
351     screen centre. Previously some were "poDesigned" which may be inappropriate
352     for multi monitor desktops.
353    
354 tony 80 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
355    
356     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
357     a transaction and always reset the object.
358    
359     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
360    
361     13. TIBXScript: Allow for override of database filename in Create Database statements.
362    
363     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
364     to a gbak format archive.
365    
366     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
367    
368     16. IBLocaldb: Drop database if error creating an empty database.
369    
370     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
371     unless selected node not in current dataset.
372    
373     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
374     to TIBCustomService, and IBlocalDB code tidy up.
375    
376     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
377     behaviour due to uninitialised variable.
378    
379     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
380     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
381    
382     21. IBSQL: When Database changed ensure that all resources are freed.
383    
384     22. IBCustomDataset: When database changed ensure that queries an unprepared.
385    
386 tony 84 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
387     * Line Wrap on SQL Token boundaries (on user command)
388     * auto-complete table names in drop down list of table names
389     * Double click on tablename or field name adds to SQL text
390 tony 80
391     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
392    
393     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
394     TVariantArray. Seems to avoid memory corruption in Windows (probably a
395     workaround for a problem in fpc 3.0.4 win64).
396    
397     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
398

400    
401 tony 51 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
402 tony 49
403 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
404 tony 49 include remote system name.
405    
406     2. TIBExtract: No longer include comment header and COMMIT statement for empty
407     tables when data included in output.
408    
409     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
410     and timing information to be written to stdout. This may be used to locate
411     performance bottlenecks.
412    
413     4. SQLParser: only call "OnChanging" event handler when value is different.
414    
415     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
416    
417 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
418     that BindFields is called when the query is next activated. Avoids FieldName
419     not found error.
420    
421 tony 80 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
422     purpose and allows the programmer to define any action they want for Update, Insert
423     or Delete. This may be complex SQL (similar to a Trigger), application specific
424     filtering of updates, or use of statements such as Grant or Revoke instead of
425     normal DML. See User Manual for more information.
426    
427 tony 47 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
428 tony 45
429 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
430 tony 45
431 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
432    
433     3. TIBExtract: data formatted as Charset set "octets" is now output using
434     hexadecimal notation.
435    
436     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
437     using a simple XML format.
438    
439     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
440     grants to these objects.
441    
442     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
443     dependency problems restoring complex databases.
444    
445     7. TIBXScript: This component has been restructured to allow for the processing of
446     embedded XML in INSERT statements and to support interactive sources in addition
447     to non-interactive data sources such as files.
448    
449     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
450    
451     9. TIBXScript: ISQL compatiable Set statements are now supported:
452     SET SQL DIALECT
453     SET TERM
454     SET AUTODDL
455     SET BAIL
456     SET ECHO
457     SET COUNT
458     SET STATS
459     SET NAMES <character set>
460    
461     10. IBVersion unit added to hold current IBX Version Number information.
462    
463     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
464     and domain definitions.
465    
466     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
467     fully supported.
468    
469     13. TIBExtract: when a database dump includes data, the generator values are now also set.
470    
471     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
472

474    
475 tony 50 See also doc/IBX4LazarusGuide.pdf for important information on
476 tony 45 upgrading to IBX2.
477    
478     1. Size property of TIBStringField is now the width in characters of the field
479     and not the byte length. This applies only to multi-byte character sets such
480     as UTF8. The original approach aligned with TStringField. However, the TStringField
481     code is not recognised as a bug and hence this change to align the behaviour.
482     The TStringField change is expected in fpc 3.2.0.
483    
484     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
485     true (default) then Size property value saved in the lfm is ignored. Size is
486     always set from the dynamic information read from the database. It is unclear
487     why anyone would want to override this and set Size to false.
488    
489     3. ibxscript: should now handle correctly a Case..End statement within a procedure
490     block.
491    
492     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
493     exist when an attempt is made to connect to it (run time only) then an attempt
494     is made to create the database.
495    
496     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
497     has been successfully created as a result of a call to CreateDatabase or when
498     creating a database after it was found not to exist.
499    
500     6. DBControlGrid: a race condition could result in the wrong row image being
501     written to the cache. This has been avoided by a trip round the message
502     loop before rendering the row image.
503    
504     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
505     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
506     known to risk corrupt rendering of row images when the control is first
507     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
508     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
509    
510     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
511     a TDateEdit control located on an editor panel.
512    
513     9. TIBExtract: brought up-to-date plus many bug fixes.
514    
515     10. DBControlGrid: Removed memory leak when updating rows.
516    
517     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
518    
519 tony 43 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
520    
521     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
522     when target codepage is CP_NONE. This is a workaround for
523     http://bugs.freepascal.org/view.php?id=30622.
524    
525     2. DBLog option removed from TIBStatisticalService - not supported by server
526     since Firebird 1.5.
527    
528     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
529     similar.
530    
531     4. IBCodePage: updated mapping between codepages and character id.
532    
533     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
534     Firebird. Character sets with a char width of two are not UTF16.
535    
536     6. Strings received from the database are now always transliterated into UTF8
537     regardless of the database character set or connection character set. This
538     is for compatibility with the LCL.
539    
540 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
541 tony 41
542     1. IBBlob: Defer reading of blob until read method called. This avoids having to
543     read in an entire blob just to get the size of the blob. General performance
544     improvement when opening datasets containing blobs.
545    
546     2. Clearing a Blob now sets the corresponding field's modified flag.
547    
548     3. IBLookupCombo: When not performing auto-complete, original query sort order
549     is now used.
550    
551     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
552     determined.
553    
554     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
555    
556     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
557     lazarus 1.6.0
558    
559     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
560     compilation error.
561    
562 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
563    
564     1. No character set specified for connection: when a text blob is retrieved, the
565     character set is determined by looking up the native character set using then
566     Firebird API. Otherwise a text mode blob is assumed to have the same character
567     set as the connection.
568    
569     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
570     for Login Dialog returing a change to the database path.
571    
572     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
573     to be changed from that given in the TIBDatabase/TIBServer component and for the
574     entered value to be saved on a project specific basis (design time only).
575    
576     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
577     column fieldname. If they are the same then it is acts as a look up for the KeyValue
578     Otherwise, it sets the column text to the selected ListField Value.
579    
580     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
581     column width.
582    
583     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
584     and a case insensitive search is requested.
585    
586     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
587     or column ListSource.
588    
589     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
590     unprepare) when closing and the text has not changed.
591    
592     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
593     Less likely to cause a cursor re-use error on Windows.
594    
595     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
596     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
597    
598     11. TIBTreeView: Guard against nil destination on record changed
599    
600     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
601     string type with the code page set to reflect the returned field encoding after
602     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
603     earlier versions.
604    
605     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
606     will now result in transliteration to the code page specified for the Firebird driver
607     if the assigned string has a different code page. FPC 3.0.0 onwards only.
608    
609     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
610     is ignored and the lc_ctype value, when the database is opened, is set to align with
611     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
612     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
613     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
614     the GETACP is used to determine the Windows code page.
615    
616     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
617     name used as the lc_ctype when the database was opened. Only valid while the
618     Database is connected.
619    
620     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
621     id that corresponds to the DefaultCharSetName.
622    
623 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
624    
625     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
626     path is given and database attach fails due to access permission issues on the
627     temp directory or security database, then the attach is retried with "localhost:"
628     prefixing the databasename. This should avoid problems when the database has to
629     be accessed by a local (e.g. classic) server and libfbembed is used.
630    
631     2. Windows: revised search order for Firebird DLL:
632     i. The Firebird Embedded Server in the application Directory.
633     ii. If the FIREBIRD environment variable is set then the directory this
634     points to is searched for the FB Client DLL and then then underlying
635     "bin" directory.
636     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
637     is used to locate the Firebird installation directory and the underlying
638     "bin" directory is searched for the FB Client DLL.
639     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
640     are searched for the FB Client DLL.
641     v. The PATH Environment variable is used to search for the FB Client DLL.
642     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
643    
644     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
645     See doc/readme.scriptengine and example applications.
646    
647     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
648     simplify the use of the embedded firebird server on both Linux and Windows platforms.
649     See dpc/readme.localdatabase and example applications.
650    
651     5. IBDynamicGrid: Reordering on column header click should now also work for
652     dynamic columns.
653    
654     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
655     between incrementing/decrementing the lock count and signalling the event.
656    
657 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
658    
659 tony 37 1.3.2 was never formally released and only made available as beta copies.
660    
661 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
662    
663     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
664    
665     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
666    
667     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
668     i.e. when it is a calculated field
669    
670     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
671     This problem was due to a race condition between recalculating row heights and
672     determining which row was selected by the mouse click. The row height calculation
673     is now deferred by an extra trip round the message loop allowing the row to
674     be always calculated on the current grid layout rather than risking it being
675     calculated on the grid layout after the expanded row has been shrunk.
676    
677     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
678     Windows.
679    
680     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
681     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
682 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
683 tony 35
684     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
685 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
686 tony 35
687     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
688     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
689 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
690 tony 35
691     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
692     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
693     implies no truncation.
694    
695     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
696    
697     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
698     (avoids "Not in Edit Mode" error).
699    
700     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
701    
702     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
703     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
704    
705     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
706    
707     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
708    
709     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
710    
711     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
712    
713 tony 33 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
714 tony 31
715     1. OnCloseUp Event Handler added to TDBLookupProperties
716    
717     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
718     problem with row size when exception is called.
719    
720     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
721    
722     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
723     in a TCustomComboBox and ignores return key if in a TCustomMemo
724    
725     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
726     keyed in i.e. when autocomplete not performed
727    
728 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
729     console mode applications with all LCL required functions (builtin dialogs and
730     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
731     not included in your project, IBX should compile and link with a console mode program.
732     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
733     console mode application or the IDE will automatically assume that your
734     application is GUI based. Instead, you should include the ibexpressconsolemode package.
735 tony 31
736     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
737     to use the built in dialogs and cursor management. IBDialogs is
738 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
739 tony 31 This should be the case for all projects created through the IDE. This is why
740     you do not want to add the ibexpress package to console mode applications. The
741     ibexpressconsolemode package has been created to allow console mode programs
742     to avoid adding LCL dependencies when using IBX, while still having the
743     unit search paths set up correctly.
744    
745 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
746     each project's source file (*.lpr).
747    
748 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
749     exists, you have to first open the package in the IDE and then close it. This
750     adds it to the most recently accessed packages list. To make it permanently
751     available, add the package name to lazarus' staticpackages.inc file.
752    
753 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
754 tony 31
755     7. SQL Parser can now accept quoted strings that include new lines
756    
757     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
758     of text on start of edit. This is particularly useful when tabbing to a
759     column and then inserting text.
760    
761     9. New Examples provided for IB Services and ISQLMonitor.
762    
763     10. Fix error when writing to blob streams that recorded only the last buffer
764     write in the blob stream. In most cases, this did not cause a problem as the
765     IB Blob Stream is written in a single write. However, with the TDBImage, write
766     of a graphic type prefix was lost which caused a problem when the image could
767     not be automatically recognised.
768    
769     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
770 tony 33 already open" errors due to random numbers used for the cursor name being identical.
771 tony 31
772     12. IBTable: corrected error that could result in an "Index out of bounds" error
773     when opening the table and the Primary Key is the last or only column in the
774     table. Thanks to Rick Hoover for the fix.
775    
776 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
777     of "UTF-8", and update list of available database character sets. Existing
778     users should check the current lc_ctype setting in their applications.

780 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
781    
782 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
783     empty Params property.
784    
785     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
786     Link now set up in Loaded method - avoids occasional failure to apply
787     SQL markup on initial open.
788    
789     3. "Employees" example performance improvements when scrolling.
790    
791     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
792     TFrame. Force recaching of selected frame to avoid GTK race (results in a
793     random image cached).
794    
795     5. DBControlGrid: Should now react to changes in panel height at run time.
796    
797     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
798     even when further rows exist.
799    
800     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
801     always be derived from panel height and setting this property can cause confusion.
802     Note for existing projects: to avoid a missing property error at run time,
803     each form using the DBControlGrid must be opened, updated and saved in the IDE
804     in order to remove the property value from the lfm.
805    
806

808 tony 27
809     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
810     call Prepare before setting parameter values.
811    
812     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
813    
814     3. Code tidyup and more robust handling of dsql information result vector.
815    
816     4. Support for centralised handling of transaction status changes. TIBTransaction
817     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
818     and "AfterExecQuery". The first three are called after the same event is called
819     for an IBCustomDataSet descendent using the Transaction. The fourth is called
820     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
821     enable monitoring of transaction status changes for a given transaction to be
822     handled in a single place. For example, when a change to the dataset occurs
823     an indicator can be set that shows the user that in order to save changes,
824     the transaction should be committed. Rather than doing this per dataset, this
825     can now be done per transaction.
826    
827     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
828     the dataset is scrolled. However, any changes to the current row are, by default,
829     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
830     have a new property "DataSetCloseAction" that adds automatic posting of changes
831     on dataset close. If this property is set to dcDiscardChanges (default) then the
832     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
833     then IBX will attempt to post any unsaved changes before the dataset is closed
834     (and after the BeforeClose event handler is called). The exception is when the
835     dataset is being closed as a result of a transaction rollback. In this case,
836     no action is taken and any unsaved changes are discarded. This avoids both
837     unnecessary overhead and the risk that a validation error may occur in the Post
838     raising an exception and thereby preventing a rollback.
839    
840     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
841     In earlier versions, the Display Width was set to the maximum byte width rather than the character
842     width. Display Widths are now corrected by dividing by the max byte width per character.
843     For UTF8 character sets, the byte width is four and hence the Display Width will be
844     the byte width divided by 4. The byte width of each character set is determined
845     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
846     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
847    
848     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
849    
850     8. IBLookupComboEditBox: List should now always be restored to full list when the
851     control loses focus. Default Key press default interval reduced to 200ms.
852    
853     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
854     when dataset rows are less than visible rows.
855    
856     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
857     does not exist or DataSet is empty. More responsive on dataset open. New event
858     OnRestorePosition. Column sort disabled if no header row.
859    
860     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
861     while dataset state is dsInsert. Avoids posting errors.
862    
863     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
864     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
865    
866     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
867    
868     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
869     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
870     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
871     always "posts" the current record regardless or whether or not it may be more appropriate
872     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
873     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
874     as the first action of the "Post" method and allows the handler to convert the Post
875     into a Cancel if that is the appropriate action on moving to a different row. This is
876     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
877     raised here, but it may still be more appropriate to validate a post and signal
878     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
879    
880     15. On Unix derived systems, the Firebird library name can now be given as a colon
881     separated list. Each library name on the list is tried in turn, in left to right
882     order with the first found being used as the firebird library. By default, on Linux,
883     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
884     overidden by the FBLIB environment variable or the OnGetLibraryName function.
885    
886     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
887     then it will still attempt to access the database via the Firebird Server and will
888     require a username and password. If only the pathname is given, then the username
889     and password should be omitted and the unix file permissions are used to grant
890     access.

893 tony 23
894     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
895     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
896     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
897 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
898 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
899    
900     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
901 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
902 tony 23 takes place during database access. This may be useful when there are performance issues with
903     the change of cursor. Setting the property to false suppresses the change of cursor.
904    
905     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
906     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
907     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
908     making all changes permanent immediately rather than when the transaction is explicitly
909     committed.
910    
911 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
912 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

919 tony 21
920     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
921     This is typically used during an "OnBeforeOpen" event handler to manipulate the
922     "Where" and "Having" clauses to implement user specified filters of arbitrary
923     complexity.
924    
925     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
926     three new data aware controls dependent on IBX and which make use of the SQL Parser.
927     These are:
928    
929     - TIBLookupComboEditBox
930     - TIBDynamicGrid
931     - TIBTreeview
932    
933     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
934     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
935     to revise the available list and restrict it to items that are prefixed by the
936 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
937 tony 21 newly typed entry to be added to the list dataset and included in the available
938     list items.
939    
940     TIBDynamicGrid is a TDBGrid descendent that provides for:
941     - automatic resizing of selected columns to fill the available row length
942     - automatic positioning and sizing of a "totals" control, typically at the
943     column footer, on a per column basis.
944     - DataSet resorting on header row click, sorting the dataset by the selected column.
945     A second click on the same header cell reversed the sort order.
946     - Support for a "Panel Editor". That is on clicking the indicator column, the row
947     is automatically expanded and a panel superimposed on it. The panel can have any
948     number of child controls, typically data aware controls with the same datasource
949     as the grid allowing for editing of additional fields and more complex editors.
950     - Reselection of the same row following resorting.
951     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
952     Its properties are specified on a per column basis and allows for one or more
953     columns to have their values selected from a list provided by a dataset.
954     Autocomplete and autoinsert are also available. The existing picklist editor
955     is unaffected by the extension.
956    
957     TIBTreeView is a data aware TCustomTreeView.
958    
959     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
960     zero scale will no longer return an error. An Int64 will be returned instead.
961    
962     4. TIBTransaction now has events for Before and After Transaction End and a new function
963     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
964    
965     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
966     repeated multiple times.
967    
968     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
969     check used to get in the way of using Stored Procedures, and "Update or Insert"
970     statements.
971    
972     7. Insert, Modify and Delete property Editors now support Query Generation from
973     Stored Procedures.
974    
975     8. Three new examples illustrate the use of the new IB Controls
976

979 tony 19
980     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
981     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
982     Gabor Boros for reporting this problem and for testing the improvements).
983    
984     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
985     See readme.field+param.names in the doc folder.
986    
987     3. IBX SQL Editors will now automatically add double quotes around column names when the database
988     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
989    
990     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
991    
992     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
993     actions.
994    
995     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
996     thanks to Yuriy Kopnin for pointing this out).
997    
998     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
999    
1000     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1001     for both fields and parameter setting.
1002    
1003     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1004     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1005    
1006     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1007     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1008    
1009     11. TIBTable now has a property editor for "MasterFields"
1010    
1011     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1012     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1013    
1014     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1015     of settings is unrecognised. Selecting this radio button has no effect on the settings.

1023    
1024     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1025     it is null. This allows for alternative user defined setting of the generator
1026    
1027     Many thanks to Julio Jiménez for this fix
1028    
1029     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1030     and suggests that the user may have forgotten to install it.
1031

1034     1. Conditional compilation used to limit registration of TIntegerField to
1035     Lazarus versions less than 1.1
1036    
1037     2. When a database connection is created, character set is now by default set
1038     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1039     1250 to 1254.

1049     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1050     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1051    
1052     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1053     package is changed to do this (which it should do).
1054

1056    
1057     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1058    
1059     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1060    
1061     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1062    
1063     4. Property editors should now correctly resize.
1064    
1065     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1066     (restored original functionality)
1067    
1068     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1069     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
