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

405 tony 49
406 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
407 tony 49 include remote system name.
408    
409     2. TIBExtract: No longer include comment header and COMMIT statement for empty
410     tables when data included in output.
411    
412     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
413     and timing information to be written to stdout. This may be used to locate
414     performance bottlenecks.
415    
416     4. SQLParser: only call "OnChanging" event handler when value is different.
417    
418     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
419    
420 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
421     that BindFields is called when the query is next activated. Avoids FieldName
422     not found error.
423    
424 tony 80 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
425     purpose and allows the programmer to define any action they want for Update, Insert
426     or Delete. This may be complex SQL (similar to a Trigger), application specific
427     filtering of updates, or use of statements such as Grant or Revoke instead of
428     normal DML. See User Manual for more information.

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

783 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
784    
785 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
786     empty Params property.
787    
788     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
789     Link now set up in Loaded method - avoids occasional failure to apply
790     SQL markup on initial open.
791    
792     3. "Employees" example performance improvements when scrolling.
793    
794     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
795     TFrame. Force recaching of selected frame to avoid GTK race (results in a
796     random image cached).
797    
798     5. DBControlGrid: Should now react to changes in panel height at run time.
799    
800     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
801     even when further rows exist.
802    
803     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
804     always be derived from panel height and setting this property can cause confusion.
805     Note for existing projects: to avoid a missing property error at run time,
806     each form using the DBControlGrid must be opened, updated and saved in the IDE
807     in order to remove the property value from the lfm.
808

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

896 tony 23
897     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
898     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
899     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
900 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
901 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
902    
903     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
904 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
905 tony 23 takes place during database access. This may be useful when there are performance issues with
906     the change of cursor. Setting the property to false suppresses the change of cursor.
907    
908     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
909     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
910     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
911     making all changes permanent immediately rather than when the transaction is explicitly
912     committed.
913    
914 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
915 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

922 tony 21
923     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
924     This is typically used during an "OnBeforeOpen" event handler to manipulate the
925     "Where" and "Having" clauses to implement user specified filters of arbitrary
926     complexity.
927    
928     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
929     three new data aware controls dependent on IBX and which make use of the SQL Parser.
930     These are:
931    
932     - TIBLookupComboEditBox
933     - TIBDynamicGrid
934     - TIBTreeview
935    
936     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
937     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
938     to revise the available list and restrict it to items that are prefixed by the
939 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
940 tony 21 newly typed entry to be added to the list dataset and included in the available
941     list items.
942    
943     TIBDynamicGrid is a TDBGrid descendent that provides for:
944     - automatic resizing of selected columns to fill the available row length
945     - automatic positioning and sizing of a "totals" control, typically at the
946     column footer, on a per column basis.
947     - DataSet resorting on header row click, sorting the dataset by the selected column.
948     A second click on the same header cell reversed the sort order.
949     - Support for a "Panel Editor". That is on clicking the indicator column, the row
950     is automatically expanded and a panel superimposed on it. The panel can have any
951     number of child controls, typically data aware controls with the same datasource
952     as the grid allowing for editing of additional fields and more complex editors.
953     - Reselection of the same row following resorting.
954     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
955     Its properties are specified on a per column basis and allows for one or more
956     columns to have their values selected from a list provided by a dataset.
957     Autocomplete and autoinsert are also available. The existing picklist editor
958     is unaffected by the extension.
959    
960     TIBTreeView is a data aware TCustomTreeView.
961    
962     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
963     zero scale will no longer return an error. An Int64 will be returned instead.
964    
965     4. TIBTransaction now has events for Before and After Transaction End and a new function
966     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
967    
968     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
969     repeated multiple times.
970    
971     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
972     check used to get in the way of using Stored Procedures, and "Update or Insert"
973     statements.
974    
975     7. Insert, Modify and Delete property Editors now support Query Generation from
976     Stored Procedures.
977    
978     8. Three new examples illustrate the use of the new IB Controls
979

982 tony 19
983     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
984     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
985     Gabor Boros for reporting this problem and for testing the improvements).
986    
987     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
988     See readme.field+param.names in the doc folder.
989    
990     3. IBX SQL Editors will now automatically add double quotes around column names when the database
991     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
992    
993     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
994    
995     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
996     actions.
997    
998     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
999     thanks to Yuriy Kopnin for pointing this out).
1000    
1001     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1002    
1003     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1004     for both fields and parameter setting.
1005    
1006     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1007     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1008    
1009     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1010     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1011    
1012     11. TIBTable now has a property editor for "MasterFields"
1013    
1014     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1015     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1016    
1017     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1018     of settings is unrecognised. Selecting this radio button has no effect on the settings.

1026    
1027     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1028     it is null. This allows for alternative user defined setting of the generator
1029    
1030     Many thanks to Julio Jiménez for this fix
1031    
1032     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1033     and suggests that the user may have forgotten to install it.
1034

1036    
1037     1. Conditional compilation used to limit registration of TIntegerField to
1038     Lazarus versions less than 1.1
1039    
1040     2. When a database connection is created, character set is now by default set
1041     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1042     1250 to 1254.

1052     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1053     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1054    
1055     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1056     package is changed to do this (which it should do).
1057

1059    
1060     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1061    
1062     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1063    
1064     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1065    
1066     4. Property editors should now correctly resize.
1067    
1068     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1069     (restored original functionality)
1070    
1071     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1072     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
