1 tony 225 IBX Change Log version (2.3-0) Tue, 03 Apr 2018 10:03:02 +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     20. Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
104     stubs. Pedantic fix really, as procedures output in dependency order anyway.
105    
106     21. TIBExtact: Package Headers and Package Bodies are now included in the extracted
107     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     23. Single Line Comments starting with '--' are now ignored when occurring
118     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 209 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
130    
131 tony 151 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
132 tony 152 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
133 tony 151 RELEASE.
134    
135     NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
136    
137 tony 107 1. IBExtract: Identity columns - add additional check for null column for generator name.
138 tony 101
139     2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
140     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
141 tony 107 information). However, this is also a very useful mechanism for returning updated computed by
142     column values. Values returned as a result of executing an Insert or Update statement
143     replace existing values in the current row for each corresponding column.
144 tony 101
145 tony 107 Previously, if a dataset's select query included read only (computed by) fields then
146     an automatic row refresh was performed after an insert or update query had been processed,
147     irrespective of the setting of the "ForcedUpdates" property. This has changed such
148     that an automatic refresh is no longer performed if an insert or update query contains
149     a returning clause that updates one or more fields on the current row. A full row
150     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
151     field values and the select query contains read only fields. Use of Insert/update
152 tony 123 returning should be significantly more efficient than executing a refresh query.
153 tony 107
154     This behaviour change is intended to be backwards compatible and there should be no need to change
155     existing programs, other than to improve performance by using the new capability.
156    
157 tony 118 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
158     they are called when the dataset row is being deleted, there is no value in
159     updating the current record from the query result. Instead, a new event handler
160     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
161     an OnDeleteReturning event handler is provided then it is called with the IResults returned
162     by the query. The event handler can then interrogate the query results and
163     perform whatever action is necessary. For example to confirm, to the user,
164     the deletion of a row with the returned values.
165    
166     4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
167 tony 107 any Computed By or Identity Columns. The IBTables example has been updated to
168     illustrate the computation of the employee Full Name on update.
169    
170 tony 118 5. TIBTable: The GeneratorField property is now published.
171 tony 107
172 tony 118 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
173 tony 101 When InsertSQL is generated, the Identity columns are not included in the list of values to
174     be inserted. A RETURNING clause is added to the insert statement to return the value of
175     each Identity column after the insert is executed.
176    
177 tony 118 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
178 tony 107 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
179     Insert..Returning clause.
180 tony 104
181 tony 118 8. TIBGenerator: small performance improvement by not preparing query each time
182 tony 107 a new value is generated.
183 tony 104
184 tony 118 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
185 tony 107
186 tony 118 10. Property editors will now sync table name to a System Table when "Include System
187     Tables" is selected and the query is for a System Table.
188 tony 105
189 tony 118 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
190 tony 107 values are no longer converted to milliseconds from TDateTime and then back again
191     to TDateTime (the conversion to milliseconds is the default TDataset approach).
192 tony 105
193 tony 118 12. Property Editors handling of Stored Procedures.
194 tony 107 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
195     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
196     query).
197     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
198 tony 106
199 tony 118 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
200 tony 107 can be used to select a package. If non-empty, the stored procedure name is
201     expected to be a stored procedure defined in the specified package and the
202     generated SQL will be as required for a stored procedure located in a package.
203    
204 tony 118 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
205 tony 107 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
206     which a stored procedure can be selected. With no package name selected, non-package
207     stored procedures are listed.
208    
209 tony 118 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
210 tony 109 for password on reconnect.
211 tony 107
212 tony 143 16. TIBDatabase: use IAttachment for connection default character set id, code page
213 tony 118 and character set name.
214 tony 109
215 tony 118 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
216     DB info lookups"
217    
218 tony 143 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
219 tony 118
220 tony 127 19. Add a property Editor for TIBUpdate.RefreshSQL.
221 tony 118
222 tony 139 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
223     parameters. This stops an exception being raised when the field cannot be
224     located in the record buffer.
225 tony 127
226 tony 141 21. Property Editors now automatically include System Tables when opened and when the query table
227     is a System Table.
228 tony 139
229 tony 150 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
230 tony 143 This avoids errors due to a stale SQRB or SRB being used for the next query.
231 tony 141
232 tony 143 23. IBServices: Service attach parameters now include "expected_db". This is used to
233     add the SPB item isc_spb_expected_db. This names a database using
234     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
235     database. examples/services re-written to illustrate use of "expected_db".
236 tony 141
237 tony 143 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
238     This avoids truncated backups when the server returns a timeout (busy) response.
239    
240     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
241    
242     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
243     databasenames. These are respectively expanded to the local system's temp directory
244 tony 150 (including trailing delimiter) or to a prescribed data directory (including
245 tony 143 trailing delimiter). Under Unix systems the data directory is a hidden directory
246     in the user's home directory. The hidden directory name is either the string returned
247     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
248     Under Windows, the directory is the same as the Data Directory as decribed
249     above but instead prefixed by the User's application data path. These may be
250 tony 150 used to improve application portability for Personal Databases.
251 tony 143
252     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
253     this has not worked for a long time and is not useful either. FieldDefs should be
254     managed using the Fields Editor as with any other dataset. To access the fields
255     editor for a TIBTable component, double click on the component. The fields editor
256     is then displayed.
257    
258     28. TIBDatabaseInfo: new properties/function
259     * DateDBCreated (returns date/time database created)
260     * TransactionCount (returns no. of active transactions)
261     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
262     * PagesFree (Firebird 3 or later)
263     * PagesUsed (Firebird 3 or later)
264     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
265     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
266    
267     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
268    
269     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
270    
271     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
272     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
273    
274     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
275     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
276     firing during backup and restore.
277    
278     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
279     for verbose output using the new property "StatisticsRequested".
280     see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
281    
282     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
283    
284     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
285     palette. This uses the online validation feature added in Firebird 2.5. The
286     services's properties enable inclusion/exclusion of tables and indexes using
287     regular expressions. See.
288     https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
289    
290     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
291     option on a database.
292    
293     37. TIBCustomService: Assign method implemented to allow copying of service login
294     context between service API components. "Detach" method now only detaches
295     service when last reference to the service interface detaches. Tidy up of
296     code for SetActive and Attach methods including password hiding.
297    
298 tony 150 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
299 tony 143 and used to determine the auth method and protocol used for the connection.
300    
301     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
302     a Create Database Statement generated by IBX.
303    
304     40. All IBServices now have an additional published property "PortNo". This may
305     be set to a non-standard port number when necessary. If zero then the default
306     port number is used.
307    
308     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
309     and not just the mouse.
310    
311     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
312    
313     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
314     image index and selected image index for each node to be set from a database field.
315    
316     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
317     then database schema includes grants to all users. If not present then the
318     only user grants included are those to User PUBLIC.
319    
320     45. TIBTreeView: performance improvement. When expanding include both expanded node
321     and child nodes in dataset.
322    
323    
324 tony 90 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
325 tony 56
326     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
327     changes.
328    
329 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
330     Bug could result in truncated multi-byte character set values.
331    
332 tony 60 3. Changes consequential on moving fbintf character set utility functions from
333     IFirebirdAPI to IAttachment.
334    
335 tony 62 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
336    
337 tony 64 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
338     results in autocomplete ignoring prefix text.
339    
340 tony 65 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
341     entering a new name into the text box.
342    
343 tony 66 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
344     Firebird rather than recomputing it.
345    
346 tony 67 8. Property Editor positioning tidy up: All IBX Property editors should now be
347     screen centre. Previously some were "poDesigned" which may be inappropriate
348     for multi monitor desktops.
349    
350 tony 80 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
351    
352     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
353     a transaction and always reset the object.
354    
355     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
356    
357     13. TIBXScript: Allow for override of database filename in Create Database statements.
358    
359     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
360     to a gbak format archive.
361    
362     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
363    
364     16. IBLocaldb: Drop database if error creating an empty database.
365    
366     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
367     unless selected node not in current dataset.
368    
369     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
370     to TIBCustomService, and IBlocalDB code tidy up.
371    
372     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
373     behaviour due to uninitialised variable.
374    
375     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
376     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
377    
378     21. IBSQL: When Database changed ensure that all resources are freed.
379    
380     22. IBCustomDataset: When database changed ensure that queries an unprepared.
381    
382 tony 84 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
383     * Line Wrap on SQL Token boundaries (on user command)
384     * auto-complete table names in drop down list of table names
385     * Double click on tablename or field name adds to SQL text
386 tony 80
387     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
388    
389     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
390     TVariantArray. Seems to avoid memory corruption in Windows (probably a
391     workaround for a problem in fpc 3.0.4 win64).
392    
393     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
394    
395 tony 83 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
396    
397 tony 51 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
398 tony 49
399 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
400 tony 49 include remote system name.
401    
402     2. TIBExtract: No longer include comment header and COMMIT statement for empty
403     tables when data included in output.
404    
405     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
406     and timing information to be written to stdout. This may be used to locate
407     performance bottlenecks.
408    
409     4. SQLParser: only call "OnChanging" event handler when value is different.
410    
411     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
412    
413 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
414     that BindFields is called when the query is next activated. Avoids FieldName
415     not found error.
416    
417 tony 80 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
418     purpose and allows the programmer to define any action they want for Update, Insert
419     or Delete. This may be complex SQL (similar to a Trigger), application specific
420     filtering of updates, or use of statements such as Grant or Revoke instead of
421     normal DML. See User Manual for more information.

424 tony 45
425 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
426 tony 45
427 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
428    
429     3. TIBExtract: data formatted as Charset set "octets" is now output using
430     hexadecimal notation.
431    
432     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
433     using a simple XML format.
434    
435     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
436     grants to these objects.
437    
438     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
439     dependency problems restoring complex databases.
440    
441     7. TIBXScript: This component has been restructured to allow for the processing of
442     embedded XML in INSERT statements and to support interactive sources in addition
443     to non-interactive data sources such as files.
444    
445     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
446    
447     9. TIBXScript: ISQL compatiable Set statements are now supported:
448     SET SQL DIALECT
449     SET TERM
450     SET AUTODDL
451     SET BAIL
452     SET ECHO
453     SET COUNT
454     SET STATS
455     SET NAMES <character set>
456    
457     10. IBVersion unit added to hold current IBX Version Number information.
458    
459     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
460     and domain definitions.
461    
462     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
463     fully supported.
464    
465     13. TIBExtract: when a database dump includes data, the generator values are now also set.
466    
467     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
468    
469     IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
470    
471 tony 50 See also doc/IBX4LazarusGuide.pdf for important information on
472 tony 45 upgrading to IBX2.
473    
474     1. Size property of TIBStringField is now the width in characters of the field
475     and not the byte length. This applies only to multi-byte character sets such
476     as UTF8. The original approach aligned with TStringField. However, the TStringField
477     code is not recognised as a bug and hence this change to align the behaviour.
478     The TStringField change is expected in fpc 3.2.0.
479    
480     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
481     true (default) then Size property value saved in the lfm is ignored. Size is
482     always set from the dynamic information read from the database. It is unclear
483     why anyone would want to override this and set Size to false.
484    
485     3. ibxscript: should now handle correctly a Case..End statement within a procedure
486     block.
487    
488     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
489     exist when an attempt is made to connect to it (run time only) then an attempt
490     is made to create the database.
491    
492     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
493     has been successfully created as a result of a call to CreateDatabase or when
494     creating a database after it was found not to exist.
495    
496     6. DBControlGrid: a race condition could result in the wrong row image being
497     written to the cache. This has been avoided by a trip round the message
498     loop before rendering the row image.
499    
500     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
501     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
502     known to risk corrupt rendering of row images when the control is first
503     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
504     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
505    
506     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
507     a TDateEdit control located on an editor panel.
508    
509     9. TIBExtract: brought up-to-date plus many bug fixes.
510    
511     10. DBControlGrid: Removed memory leak when updating rows.
512    
513     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
514    
515 tony 43 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
516    
517     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
518     when target codepage is CP_NONE. This is a workaround for
519     http://bugs.freepascal.org/view.php?id=30622.
520    
521     2. DBLog option removed from TIBStatisticalService - not supported by server
522     since Firebird 1.5.
523    
524     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
525     similar.
526    
527     4. IBCodePage: updated mapping between codepages and character id.
528    
529     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
530     Firebird. Character sets with a char width of two are not UTF16.
531    
532     6. Strings received from the database are now always transliterated into UTF8
533     regardless of the database character set or connection character set. This
534     is for compatibility with the LCL.
535    
536 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
537 tony 41
538     1. IBBlob: Defer reading of blob until read method called. This avoids having to
539     read in an entire blob just to get the size of the blob. General performance
540     improvement when opening datasets containing blobs.
541    
542     2. Clearing a Blob now sets the corresponding field's modified flag.
543    
544     3. IBLookupCombo: When not performing auto-complete, original query sort order
545     is now used.
546    
547     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
548     determined.
549    
550     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
551    
552     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
553     lazarus 1.6.0
554    
555     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
556     compilation error.
557    
558 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
559    
560     1. No character set specified for connection: when a text blob is retrieved, the
561     character set is determined by looking up the native character set using then
562     Firebird API. Otherwise a text mode blob is assumed to have the same character
563     set as the connection.
564    
565     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
566     for Login Dialog returing a change to the database path.
567    
568     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
569     to be changed from that given in the TIBDatabase/TIBServer component and for the
570     entered value to be saved on a project specific basis (design time only).
571    
572     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
573     column fieldname. If they are the same then it is acts as a look up for the KeyValue
574     Otherwise, it sets the column text to the selected ListField Value.
575    
576     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
577     column width.
578    
579     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
580     and a case insensitive search is requested.
581    
582     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
583     or column ListSource.
584    
585     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
586     unprepare) when closing and the text has not changed.
587    
588     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
589     Less likely to cause a cursor re-use error on Windows.
590    
591     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
592     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
593    
594     11. TIBTreeView: Guard against nil destination on record changed
595    
596     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
597     string type with the code page set to reflect the returned field encoding after
598     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
599     earlier versions.
600    
601     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
602     will now result in transliteration to the code page specified for the Firebird driver
603     if the assigned string has a different code page. FPC 3.0.0 onwards only.
604    
605     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
606     is ignored and the lc_ctype value, when the database is opened, is set to align with
607     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
608     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
609     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
610     the GETACP is used to determine the Windows code page.
611    
612     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
613     name used as the lc_ctype when the database was opened. Only valid while the
614     Database is connected.
615    
616     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
617     id that corresponds to the DefaultCharSetName.
618    
619 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
620    
621     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
622     path is given and database attach fails due to access permission issues on the
623     temp directory or security database, then the attach is retried with "localhost:"
624     prefixing the databasename. This should avoid problems when the database has to
625     be accessed by a local (e.g. classic) server and libfbembed is used.
626    
627     2. Windows: revised search order for Firebird DLL:
628     i. The Firebird Embedded Server in the application Directory.
629     ii. If the FIREBIRD environment variable is set then the directory this
630     points to is searched for the FB Client DLL and then then underlying
631     "bin" directory.
632     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
633     is used to locate the Firebird installation directory and the underlying
634     "bin" directory is searched for the FB Client DLL.
635     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
636     are searched for the FB Client DLL.
637     v. The PATH Environment variable is used to search for the FB Client DLL.
638     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
639    
640     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
641     See doc/readme.scriptengine and example applications.
642    
643     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
644     simplify the use of the embedded firebird server on both Linux and Windows platforms.
645     See dpc/readme.localdatabase and example applications.
646    
647     5. IBDynamicGrid: Reordering on column header click should now also work for
648     dynamic columns.
649    
650     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
651     between incrementing/decrementing the lock count and signalling the event.
652    
653 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
654    
655 tony 37 1.3.2 was never formally released and only made available as beta copies.
656    
657 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
658    
659     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
660    
661     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
662    
663     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
664     i.e. when it is a calculated field
665    
666     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
667     This problem was due to a race condition between recalculating row heights and
668     determining which row was selected by the mouse click. The row height calculation
669     is now deferred by an extra trip round the message loop allowing the row to
670     be always calculated on the current grid layout rather than risking it being
671     calculated on the grid layout after the expanded row has been shrunk.
672    
673     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
674     Windows.
675    
676     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
677     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
678 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
679 tony 35
680     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
681 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
682 tony 35
683     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
684     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
685 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
686 tony 35
687     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
688     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
689     implies no truncation.
690    
691     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
692    
693     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
694     (avoids "Not in Edit Mode" error).
695    
696     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
697    
698     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
699     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
700    
701     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
702    
703     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
704    
705     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
706    
707     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
708    
709 tony 33 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
710 tony 31
711     1. OnCloseUp Event Handler added to TDBLookupProperties
712    
713     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
714     problem with row size when exception is called.
715    
716     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
717    
718     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
719     in a TCustomComboBox and ignores return key if in a TCustomMemo
720    
721     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
722     keyed in i.e. when autocomplete not performed
723    
724 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
725     console mode applications with all LCL required functions (builtin dialogs and
726     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
727     not included in your project, IBX should compile and link with a console mode program.
728     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
729     console mode application or the IDE will automatically assume that your
730     application is GUI based. Instead, you should include the ibexpressconsolemode package.
731 tony 31
732     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
733     to use the built in dialogs and cursor management. IBDialogs is
734 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
735 tony 31 This should be the case for all projects created through the IDE. This is why
736     you do not want to add the ibexpress package to console mode applications. The
737     ibexpressconsolemode package has been created to allow console mode programs
738     to avoid adding LCL dependencies when using IBX, while still having the
739     unit search paths set up correctly.
740    
741 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
742     each project's source file (*.lpr).
743    
744 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
745     exists, you have to first open the package in the IDE and then close it. This
746     adds it to the most recently accessed packages list. To make it permanently
747     available, add the package name to lazarus' staticpackages.inc file.
748    
749 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
750 tony 31
751     7. SQL Parser can now accept quoted strings that include new lines
752    
753     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
754     of text on start of edit. This is particularly useful when tabbing to a
755     column and then inserting text.
756    
757     9. New Examples provided for IB Services and ISQLMonitor.
758    
759     10. Fix error when writing to blob streams that recorded only the last buffer
760     write in the blob stream. In most cases, this did not cause a problem as the
761     IB Blob Stream is written in a single write. However, with the TDBImage, write
762     of a graphic type prefix was lost which caused a problem when the image could
763     not be automatically recognised.
764    
765     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
766 tony 33 already open" errors due to random numbers used for the cursor name being identical.
767 tony 31
768     12. IBTable: corrected error that could result in an "Index out of bounds" error
769     when opening the table and the Primary Key is the last or only column in the
770     table. Thanks to Rick Hoover for the fix.
771    
772 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
773     of "UTF-8", and update list of available database character sets. Existing
774     users should check the current lc_ctype setting in their applications.
775 tony 29
776 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
777    
778 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
779     empty Params property.
780    
781     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
782     Link now set up in Loaded method - avoids occasional failure to apply
783     SQL markup on initial open.
784    
785     3. "Employees" example performance improvements when scrolling.
786    
787     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
788     TFrame. Force recaching of selected frame to avoid GTK race (results in a
789     random image cached).
790    
791     5. DBControlGrid: Should now react to changes in panel height at run time.
792    
793     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
794     even when further rows exist.
795    
796     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
797     always be derived from panel height and setting this property can cause confusion.
798     Note for existing projects: to avoid a missing property error at run time,
799     each form using the DBControlGrid must be opened, updated and saved in the IDE
800     in order to remove the property value from the lfm.
801    
802    
803 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
804 tony 27
805     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
806     call Prepare before setting parameter values.
807    
808     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
809    
810     3. Code tidyup and more robust handling of dsql information result vector.
811    
812     4. Support for centralised handling of transaction status changes. TIBTransaction
813     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
814     and "AfterExecQuery". The first three are called after the same event is called
815     for an IBCustomDataSet descendent using the Transaction. The fourth is called
816     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
817     enable monitoring of transaction status changes for a given transaction to be
818     handled in a single place. For example, when a change to the dataset occurs
819     an indicator can be set that shows the user that in order to save changes,
820     the transaction should be committed. Rather than doing this per dataset, this
821     can now be done per transaction.
822    
823     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
824     the dataset is scrolled. However, any changes to the current row are, by default,
825     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
826     have a new property "DataSetCloseAction" that adds automatic posting of changes
827     on dataset close. If this property is set to dcDiscardChanges (default) then the
828     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
829     then IBX will attempt to post any unsaved changes before the dataset is closed
830     (and after the BeforeClose event handler is called). The exception is when the
831     dataset is being closed as a result of a transaction rollback. In this case,
832     no action is taken and any unsaved changes are discarded. This avoids both
833     unnecessary overhead and the risk that a validation error may occur in the Post
834     raising an exception and thereby preventing a rollback.
835    
836     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
837     In earlier versions, the Display Width was set to the maximum byte width rather than the character
838     width. Display Widths are now corrected by dividing by the max byte width per character.
839     For UTF8 character sets, the byte width is four and hence the Display Width will be
840     the byte width divided by 4. The byte width of each character set is determined
841     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
842     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
843    
844     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
845    
846     8. IBLookupComboEditBox: List should now always be restored to full list when the
847     control loses focus. Default Key press default interval reduced to 200ms.
848    
849     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
850     when dataset rows are less than visible rows.
851    
852     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
853     does not exist or DataSet is empty. More responsive on dataset open. New event
854     OnRestorePosition. Column sort disabled if no header row.
855    
856     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
857     while dataset state is dsInsert. Avoids posting errors.
858    
859     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
860     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
861    
862     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
863    
864     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
865     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
866     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
867     always "posts" the current record regardless or whether or not it may be more appropriate
868     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
869     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
870     as the first action of the "Post" method and allows the handler to convert the Post
871     into a Cancel if that is the appropriate action on moving to a different row. This is
872     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
873     raised here, but it may still be more appropriate to validate a post and signal
874     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
875    
876     15. On Unix derived systems, the Firebird library name can now be given as a colon
877     separated list. Each library name on the list is tried in turn, in left to right
878     order with the first found being used as the firebird library. By default, on Linux,
879     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
880     overidden by the FBLIB environment variable or the OnGetLibraryName function.
881    
882     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
883     then it will still attempt to access the database via the Firebird Server and will
884     require a username and password. If only the pathname is given, then the username
885     and password should be omitted and the unix file permissions are used to grant
886     access.

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

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

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

1019    
1020     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1021     it is null. This allows for alternative user defined setting of the generator
1022    
1023     Many thanks to Julio Jiménez for this fix
1024    
1025     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1026     and suggests that the user may have forgotten to install it.
1027

1030     1. Conditional compilation used to limit registration of TIntegerField to
1031     Lazarus versions less than 1.1
1032    
1033     2. When a database connection is created, character set is now by default set
1034     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1035     1250 to 1254.

1045     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1046     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1047    
1048     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1049     package is changed to do this (which it should do).
1050    
1051     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1052    
1053     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1054    
1055     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1056    
1057     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1058    
1059     4. Property editors should now correctly resize.
1060    
1061     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1062     (restored original functionality)
1063    
1064     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1065     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
