1 tony 266 IBX Change Log version (2.3-3) Wed, 26 Dec 2018 18:20:57 +0000
2    
3     This is rc1 for 2.2.3.
4    
5     1. New property for TIBDatabase and TIBXServicesConnection. This is "WireCompression".
6     If this property is set to true then the Client will request WireCompression for
7     the connection. Note: "WireCompression = true" must be set in the server's
8     "firebird.conf". This property is overridden if "WireCompression = true" is set
9     in the client "firebird.conf" when wire compression is always requested by the client.
10    
11 tony 263 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
12    
13     1. Remove need to check for IsMultiThread by providing access to GUI timers via
14     IBGUIInterface. Note: master/detail delay timer does not apply to console
15     mode apps.
16    
17     2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
18     statement. This avoids problems if "Execute Block" is used as the Query.
19    
20     3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
21     internal SQL tokeniser routines.
22    
23     4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
24     as a select statement, with or without CTEs.
25    
26     5. IBSQLParser: parser now recognises the "ROWS" clause.
27    
28     6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
29     internal SQL tokeniser routines.
30    
31     7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
32     being raised for valid set statements processed by a data formatter.
33    
34     8. New published property for TIBDatabase and TIBXServicesConnection. This is
35     FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
36     the path of the Firebird Library used by the database/services connection.
37    
38     9. New read only public property for TIBDatabase and TIBXServicesConnection. This
39     is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
40     services connection.
41    
42     10.SQL Property editors now quote parameter names if "Quote identifier" is selected
43     or param name is not a valid SQL identifier.
44    
45     11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
46     view of whether the text box should be editable when no DataSource is specified.
47     TIBLookupComboEditBox has been updated to workaround this problem. As long as
48     ReadOnly is false, the text box is editable when no DataSource is specified.
49    
50     12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
51     the FBLIB environment variable. If you do not want to permit this then you
52     must modify the Register procedure in the design/IBDBReg.pas unit to remove
53     this setting.
54    
55 tony 241 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
56    
57     1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
58     Utf8EscapeControlChars
59    
60 tony 232 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
61 tony 101
62 tony 209 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
63     all previous copies of the IBX source code tree before installing this release.
64    
65     The IBX packages used by most users have not changed, with one exception. The
66     IBServices unit has been moved to the package iblegacyServices.lpk. To continue
67     to use the IBServices unit in your applications, please add the iblegacyServices
68     to the list of dependencies. To do this, open the Project Inspector and select
69     Add->New Requirement and select "ibLegacyServices" from the list of available
70     packages.
71    
72     1. New unit IBXServices. The IBXServices unit is a re-architectured update of
73     the IBServices unit providing what is intended to be a clearer and easier to
74     use set of IB Services components. See Chapter 10 of the IBX User Guide for
75     more information and the guide to "Firebird Service Management Using IBX".
76     As indicated above, the legacy services components are still available and
77     provided in a separate package. There is no need to update working applications
78     using the older versions except for an additional package dependency.
79    
80     2. The IBX packages and source code tree have been re-organised in an attempt to
81     finally get rid of the "duplicate ppu" warnings. This re-organisation should
82     not affect existing users. Section 2.3 of the IBX User Guide describes the
83     new set of IBX packages.
84    
85     3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
86     updated to use the new Services API components.
87    
88     4. The iblocal package has been updated to use the new Services API components.
89    
90     5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
91     TIBXSecurityService. It had been wrongly classified in the previous version
92     as a per database configuration item. It is global to a server and hence
93     correctly positioned as part of the Security Package. In the DBAdmin example,
94     the setting has moved to the mappings page.
95    
96     6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
97     are ignored.
98    
99     7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
100     closed before the database is dropped. Before and After Disconnect event handlers
101     are also fired.
102    
103     8. TIBTransaction: OnStartTransaction event now fires every time the transaction
104     is started and not just the first time.
105    
106     9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
107     depenendency with comp type.
108    
109     10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
110    
111     11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
112     then this is recognised and not ignored.
113    
114     12. TIBDataSet, TIBQuery, TIBTable: additions:
115     function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
116     function GetPerfStatistics(var stats: TPerfCounters): boolean;
117     property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
118    
119     GetRowsAffected returns the affected row counts from the last insert/update/delete
120     if EnableStatistics = true then GetPerfStatistics returns the current stats
121     counters for the select query. Note: stats accumulate after each fetch from
122     the database. To get total query cost after open, call the "Last" method
123     and then GetPerfStatistics.
124    
125     See ibx/examples/consolemode for an example of the use of GetPerfStatistics
126    
127     13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
128     in parenthesises.
129    
130     14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
131     SQL identifiers are always delimited by double quotes. If false, then they are
132     only delimited if the identifier is a reserved word, contains lower case or special
133     characters. Set this property to true to retain previous behaviour.
134    
135     15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
136     are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
137    
138     16. TIBDataSet, TIBQuery, TIBTable: addition:
139     property MasterDetailDelay: integer {defaults to zero}
140    
141     When non-zero and the dataset is a detail table referencing a master table
142     through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
143     then a synchronisation delay is added (in milliseconds) between the master
144     row changing and the detail dataset being re-opened. If the master dataset
145     is scrolled before the delay expires then the delay is reset. This can be used
146     to avoid performance overheads when scrolling through a large master dataset.
147    
148     Note: uses fptimer and hence requires a thread manager. Under Linux the
149     chreads unit must be included in your project. TTimer is not used in order
150 tony 213 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
151 tony 209
152     17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
153     with Extract Option eoDatabase.
154    
155     18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
156 tony 225 When a deLayoutChanged event is reported on the ListSource dataset, the
157 tony 209 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
158     relationship with the control's datasource (master).
159    
160 tony 221 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
161    
162 tony 226 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
163 tony 221 stubs. Pedantic fix really, as procedures output in dependency order anyway.
164    
165 tony 226 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
166 tony 221 DDL (Firebird 3 and later only).
167    
168 tony 225 22. TIBLookupComboBox Autocomplete Fixes:
169     i. Only appended text is now selected after autocomplete.
170     ii. Uppercase keys no longer ignored for autocomplete.
171     iii. Retain Prefix case is now honoured correctly.
172     iv. When a DataSource is assigned, typing after autocomplete now extends prefix
173     before autocomplete performed. i.e. behaviour now the same as when
174     no DataSource assigned.
175    
176 tony 226 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
177 tony 225 between SQL statements.
178    
179     24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
180     ObjectNames are converted to upper case before matching against metadata object
181     names, unless the objectname is delimited by double quotes, in which case, the
182     double quotes are removed and the remaining string is used (unmodified) to match
183     against the metadata object name.
184    
185     If true then the ObjectName is used as is without modification and matched
186     against the metadata object name. No attempt is made to remove double quotes.
187    
188 tony 226 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
189     with eoTrigger, these extract types can be used to select only Database Triggers,
190     or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
191    
192 tony 227 26. TIBXScript: If an exception occurs during the processing of a statement, the
193     statement separate character is now reset to the default (';').
194    
195 tony 229 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
196    
197     28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
198     a commit or reconnect statement and instead activated only when next SQL statement
199     is executed.
200    
201     29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
202    
203     30. TIBXScript: case insensitive regex now used when matching statements instead of
204     converting statement to upper case.
205    
206     31. TIBExtract: metadata comments now supported. New published property
207     IncludeMetaDataComments (default true). If true then metadata comments included
208     in extracted DDL. New Extract Object member eoComments. This may be used with
209     ExtractObject method to list all metadata comments.
210    
211     32. TIBExtract: ListObjectNames method added.
212    
213 tony 231 33. Updated Database component editor to support additional connection string
214     types.
215    
216 tony 209 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
217    
218 tony 151 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
219 tony 152 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
220 tony 151 RELEASE.
221    
222     NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
223    
224 tony 107 1. IBExtract: Identity columns - add additional check for null column for generator name.
225 tony 101
226     2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
227     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
228 tony 107 information). However, this is also a very useful mechanism for returning updated computed by
229     column values. Values returned as a result of executing an Insert or Update statement
230     replace existing values in the current row for each corresponding column.
231 tony 101
232 tony 107 Previously, if a dataset's select query included read only (computed by) fields then
233     an automatic row refresh was performed after an insert or update query had been processed,
234     irrespective of the setting of the "ForcedUpdates" property. This has changed such
235     that an automatic refresh is no longer performed if an insert or update query contains
236     a returning clause that updates one or more fields on the current row. A full row
237     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
238     field values and the select query contains read only fields. Use of Insert/update
239 tony 123 returning should be significantly more efficient than executing a refresh query.
240 tony 107
241     This behaviour change is intended to be backwards compatible and there should be no need to change
242     existing programs, other than to improve performance by using the new capability.
243    
244 tony 118 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
245     they are called when the dataset row is being deleted, there is no value in
246     updating the current record from the query result. Instead, a new event handler
247     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
248     an OnDeleteReturning event handler is provided then it is called with the IResults returned
249     by the query. The event handler can then interrogate the query results and
250     perform whatever action is necessary. For example to confirm, to the user,
251     the deletion of a row with the returned values.
252    
253     4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
254 tony 107 any Computed By or Identity Columns. The IBTables example has been updated to
255     illustrate the computation of the employee Full Name on update.
256    
257 tony 118 5. TIBTable: The GeneratorField property is now published.
258 tony 107
259 tony 118 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
260 tony 101 When InsertSQL is generated, the Identity columns are not included in the list of values to
261     be inserted. A RETURNING clause is added to the insert statement to return the value of
262     each Identity column after the insert is executed.
263    
264 tony 118 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
265 tony 107 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
266     Insert..Returning clause.
267 tony 104
268 tony 118 8. TIBGenerator: small performance improvement by not preparing query each time
269 tony 107 a new value is generated.
270 tony 104
271 tony 118 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
272 tony 107
273 tony 118 10. Property editors will now sync table name to a System Table when "Include System
274     Tables" is selected and the query is for a System Table.
275 tony 105
276 tony 118 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
277 tony 107 values are no longer converted to milliseconds from TDateTime and then back again
278     to TDateTime (the conversion to milliseconds is the default TDataset approach).
279 tony 105
280 tony 118 12. Property Editors handling of Stored Procedures.
281 tony 107 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
282     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
283     query).
284     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
285 tony 106
286 tony 118 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
287 tony 107 can be used to select a package. If non-empty, the stored procedure name is
288     expected to be a stored procedure defined in the specified package and the
289     generated SQL will be as required for a stored procedure located in a package.
290    
291 tony 118 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
292 tony 107 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
293     which a stored procedure can be selected. With no package name selected, non-package
294     stored procedures are listed.
295    
296 tony 118 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
297 tony 109 for password on reconnect.
298 tony 107
299 tony 143 16. TIBDatabase: use IAttachment for connection default character set id, code page
300 tony 118 and character set name.
301 tony 109
302 tony 118 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
303     DB info lookups"
304    
305 tony 143 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
306 tony 118
307 tony 127 19. Add a property Editor for TIBUpdate.RefreshSQL.
308 tony 118
309 tony 139 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
310     parameters. This stops an exception being raised when the field cannot be
311     located in the record buffer.
312 tony 127
313 tony 141 21. Property Editors now automatically include System Tables when opened and when the query table
314     is a System Table.
315 tony 139
316 tony 150 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
317 tony 143 This avoids errors due to a stale SQRB or SRB being used for the next query.
318 tony 141
319 tony 143 23. IBServices: Service attach parameters now include "expected_db". This is used to
320     add the SPB item isc_spb_expected_db. This names a database using
321     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
322     database. examples/services re-written to illustrate use of "expected_db".
323 tony 141
324 tony 143 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
325     This avoids truncated backups when the server returns a timeout (busy) response.
326    
327     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
328    
329     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
330     databasenames. These are respectively expanded to the local system's temp directory
331 tony 150 (including trailing delimiter) or to a prescribed data directory (including
332 tony 143 trailing delimiter). Under Unix systems the data directory is a hidden directory
333     in the user's home directory. The hidden directory name is either the string returned
334     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
335     Under Windows, the directory is the same as the Data Directory as decribed
336     above but instead prefixed by the User's application data path. These may be
337 tony 150 used to improve application portability for Personal Databases.
338 tony 143
339     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
340     this has not worked for a long time and is not useful either. FieldDefs should be
341     managed using the Fields Editor as with any other dataset. To access the fields
342     editor for a TIBTable component, double click on the component. The fields editor
343     is then displayed.
344    
345     28. TIBDatabaseInfo: new properties/function
346     * DateDBCreated (returns date/time database created)
347     * TransactionCount (returns no. of active transactions)
348     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
349     * PagesFree (Firebird 3 or later)
350     * PagesUsed (Firebird 3 or later)
351     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
352     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
353    
354     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
355    
356     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
357    
358     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
359     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
360    
361     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
362     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
363     firing during backup and restore.
364    
365     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
366     for verbose output using the new property "StatisticsRequested".
367     see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
368    
369     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
370    
371     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
372     palette. This uses the online validation feature added in Firebird 2.5. The
373     services's properties enable inclusion/exclusion of tables and indexes using
374     regular expressions. See.
375     https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
376    
377     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
378     option on a database.
379    
380     37. TIBCustomService: Assign method implemented to allow copying of service login
381     context between service API components. "Detach" method now only detaches
382     service when last reference to the service interface detaches. Tidy up of
383     code for SetActive and Attach methods including password hiding.
384    
385 tony 150 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
386 tony 143 and used to determine the auth method and protocol used for the connection.
387    
388     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
389     a Create Database Statement generated by IBX.
390    
391     40. All IBServices now have an additional published property "PortNo". This may
392     be set to a non-standard port number when necessary. If zero then the default
393     port number is used.
394    
395     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
396     and not just the mouse.
397    
398     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
399    
400     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
401     image index and selected image index for each node to be set from a database field.
402    
403     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
404     then database schema includes grants to all users. If not present then the
405     only user grants included are those to User PUBLIC.
406    
407     45. TIBTreeView: performance improvement. When expanding include both expanded node
408     and child nodes in dataset.

412 tony 56
413     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
414     changes.
415    
416 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
417     Bug could result in truncated multi-byte character set values.
418    
419 tony 60 3. Changes consequential on moving fbintf character set utility functions from
420     IFirebirdAPI to IAttachment.
421    
422 tony 62 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
423    
424 tony 64 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
425     results in autocomplete ignoring prefix text.
426    
427 tony 65 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
428     entering a new name into the text box.
429    
430 tony 66 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
431     Firebird rather than recomputing it.
432    
433 tony 67 8. Property Editor positioning tidy up: All IBX Property editors should now be
434     screen centre. Previously some were "poDesigned" which may be inappropriate
435     for multi monitor desktops.
436    
437 tony 80 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
438    
439     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
440     a transaction and always reset the object.
441    
442     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
443    
444     13. TIBXScript: Allow for override of database filename in Create Database statements.
445    
446     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
447     to a gbak format archive.
448    
449     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
450    
451     16. IBLocaldb: Drop database if error creating an empty database.
452    
453     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
454     unless selected node not in current dataset.
455    
456     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
457     to TIBCustomService, and IBlocalDB code tidy up.
458    
459     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
460     behaviour due to uninitialised variable.
461    
462     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
463     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
464    
465     21. IBSQL: When Database changed ensure that all resources are freed.
466    
467     22. IBCustomDataset: When database changed ensure that queries an unprepared.
468    
469 tony 84 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
470     * Line Wrap on SQL Token boundaries (on user command)
471     * auto-complete table names in drop down list of table names
472     * Double click on tablename or field name adds to SQL text
473 tony 80
474     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
475    
476     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
477     TVariantArray. Seems to avoid memory corruption in Windows (probably a
478     workaround for a problem in fpc 3.0.4 win64).
479    
480     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
481    
482 tony 83 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
483    
484 tony 51 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
485 tony 49
486 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
487 tony 49 include remote system name.
488    
489     2. TIBExtract: No longer include comment header and COMMIT statement for empty
490     tables when data included in output.
491    
492     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
493     and timing information to be written to stdout. This may be used to locate
494     performance bottlenecks.
495    
496     4. SQLParser: only call "OnChanging" event handler when value is different.
497    
498     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
499    
500 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
501     that BindFields is called when the query is next activated. Avoids FieldName
502     not found error.
503    
504 tony 80 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
505     purpose and allows the programmer to define any action they want for Update, Insert
506     or Delete. This may be complex SQL (similar to a Trigger), application specific
507     filtering of updates, or use of statements such as Grant or Revoke instead of
508     normal DML. See User Manual for more information.
509    
510 tony 47 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
511 tony 45
512 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
513 tony 45
514 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
515    
516     3. TIBExtract: data formatted as Charset set "octets" is now output using
517     hexadecimal notation.
518    
519     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
520     using a simple XML format.
521    
522     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
523     grants to these objects.
524    
525     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
526     dependency problems restoring complex databases.
527    
528     7. TIBXScript: This component has been restructured to allow for the processing of
529     embedded XML in INSERT statements and to support interactive sources in addition
530     to non-interactive data sources such as files.
531    
532     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
533    
534     9. TIBXScript: ISQL compatiable Set statements are now supported:
535     SET SQL DIALECT
536     SET TERM
537     SET AUTODDL
538     SET BAIL
539     SET ECHO
540     SET COUNT
541     SET STATS
542     SET NAMES <character set>
543    
544     10. IBVersion unit added to hold current IBX Version Number information.
545    
546     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
547     and domain definitions.
548    
549     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
550     fully supported.
551    
552     13. TIBExtract: when a database dump includes data, the generator values are now also set.
553    
554     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
555    
556     IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
557    
558 tony 50 See also doc/IBX4LazarusGuide.pdf for important information on
559 tony 45 upgrading to IBX2.
560    
561     1. Size property of TIBStringField is now the width in characters of the field
562     and not the byte length. This applies only to multi-byte character sets such
563     as UTF8. The original approach aligned with TStringField. However, the TStringField
564     code is not recognised as a bug and hence this change to align the behaviour.
565     The TStringField change is expected in fpc 3.2.0.
566    
567     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
568     true (default) then Size property value saved in the lfm is ignored. Size is
569     always set from the dynamic information read from the database. It is unclear
570     why anyone would want to override this and set Size to false.
571    
572     3. ibxscript: should now handle correctly a Case..End statement within a procedure
573     block.
574    
575     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
576     exist when an attempt is made to connect to it (run time only) then an attempt
577     is made to create the database.
578    
579     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
580     has been successfully created as a result of a call to CreateDatabase or when
581     creating a database after it was found not to exist.
582    
583     6. DBControlGrid: a race condition could result in the wrong row image being
584     written to the cache. This has been avoided by a trip round the message
585     loop before rendering the row image.
586    
587     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
588     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
589     known to risk corrupt rendering of row images when the control is first
590     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
591     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
592    
593     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
594     a TDateEdit control located on an editor panel.
595    
596     9. TIBExtract: brought up-to-date plus many bug fixes.
597    
598     10. DBControlGrid: Removed memory leak when updating rows.
599    
600     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
601    
602 tony 43 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
603    
604     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
605     when target codepage is CP_NONE. This is a workaround for
606     http://bugs.freepascal.org/view.php?id=30622.
607    
608     2. DBLog option removed from TIBStatisticalService - not supported by server
609     since Firebird 1.5.
610    
611     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
612     similar.
613    
614     4. IBCodePage: updated mapping between codepages and character id.
615    
616     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
617     Firebird. Character sets with a char width of two are not UTF16.
618    
619     6. Strings received from the database are now always transliterated into UTF8
620     regardless of the database character set or connection character set. This
621     is for compatibility with the LCL.
622    
623 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
624 tony 41
625     1. IBBlob: Defer reading of blob until read method called. This avoids having to
626     read in an entire blob just to get the size of the blob. General performance
627     improvement when opening datasets containing blobs.
628    
629     2. Clearing a Blob now sets the corresponding field's modified flag.
630    
631     3. IBLookupCombo: When not performing auto-complete, original query sort order
632     is now used.
633    
634     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
635     determined.
636    
637     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
638    
639     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
640     lazarus 1.6.0
641    
642     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
643     compilation error.
644    
645 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
646    
647     1. No character set specified for connection: when a text blob is retrieved, the
648     character set is determined by looking up the native character set using then
649     Firebird API. Otherwise a text mode blob is assumed to have the same character
650     set as the connection.
651    
652     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
653     for Login Dialog returing a change to the database path.
654    
655     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
656     to be changed from that given in the TIBDatabase/TIBServer component and for the
657     entered value to be saved on a project specific basis (design time only).
658    
659     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
660     column fieldname. If they are the same then it is acts as a look up for the KeyValue
661     Otherwise, it sets the column text to the selected ListField Value.
662    
663     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
664     column width.
665    
666     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
667     and a case insensitive search is requested.
668    
669     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
670     or column ListSource.
671    
672     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
673     unprepare) when closing and the text has not changed.
674    
675     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
676     Less likely to cause a cursor re-use error on Windows.
677    
678     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
679     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
680    
681     11. TIBTreeView: Guard against nil destination on record changed
682    
683     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
684     string type with the code page set to reflect the returned field encoding after
685     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
686     earlier versions.
687    
688     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
689     will now result in transliteration to the code page specified for the Firebird driver
690     if the assigned string has a different code page. FPC 3.0.0 onwards only.
691    
692     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
693     is ignored and the lc_ctype value, when the database is opened, is set to align with
694     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
695     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
696     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
697     the GETACP is used to determine the Windows code page.
698    
699     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
700     name used as the lc_ctype when the database was opened. Only valid while the
701     Database is connected.
702    
703     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
704     id that corresponds to the DefaultCharSetName.
705    
706 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
707    
708     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
709     path is given and database attach fails due to access permission issues on the
710     temp directory or security database, then the attach is retried with "localhost:"
711     prefixing the databasename. This should avoid problems when the database has to
712     be accessed by a local (e.g. classic) server and libfbembed is used.
713    
714     2. Windows: revised search order for Firebird DLL:
715     i. The Firebird Embedded Server in the application Directory.
716     ii. If the FIREBIRD environment variable is set then the directory this
717     points to is searched for the FB Client DLL and then then underlying
718     "bin" directory.
719     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
720     is used to locate the Firebird installation directory and the underlying
721     "bin" directory is searched for the FB Client DLL.
722     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
723     are searched for the FB Client DLL.
724     v. The PATH Environment variable is used to search for the FB Client DLL.
725     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
726    
727     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
728     See doc/readme.scriptengine and example applications.
729    
730     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
731     simplify the use of the embedded firebird server on both Linux and Windows platforms.
732     See dpc/readme.localdatabase and example applications.
733    
734     5. IBDynamicGrid: Reordering on column header click should now also work for
735     dynamic columns.
736    
737     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
738     between incrementing/decrementing the lock count and signalling the event.
739    
740 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
741    
742 tony 37 1.3.2 was never formally released and only made available as beta copies.
743    
744 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
745    
746     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
747    
748     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
749    
750     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
751     i.e. when it is a calculated field
752    
753     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
754     This problem was due to a race condition between recalculating row heights and
755     determining which row was selected by the mouse click. The row height calculation
756     is now deferred by an extra trip round the message loop allowing the row to
757     be always calculated on the current grid layout rather than risking it being
758     calculated on the grid layout after the expanded row has been shrunk.
759    
760     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
761     Windows.
762    
763     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
764     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
765 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
766 tony 35
767     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
768 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
769 tony 35
770     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
771     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
772 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
773 tony 35
774     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
775     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
776     implies no truncation.
777    
778     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
779    
780     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
781     (avoids "Not in Edit Mode" error).
782    
783     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
784    
785     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
786     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
787    
788     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
789    
790     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
791    
792     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
793    
794     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
795    
796 tony 33 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
797 tony 31
798     1. OnCloseUp Event Handler added to TDBLookupProperties
799    
800     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
801     problem with row size when exception is called.
802    
803     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
804    
805     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
806     in a TCustomComboBox and ignores return key if in a TCustomMemo
807    
808     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
809     keyed in i.e. when autocomplete not performed
810    
811 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
812     console mode applications with all LCL required functions (builtin dialogs and
813     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
814     not included in your project, IBX should compile and link with a console mode program.
815     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
816     console mode application or the IDE will automatically assume that your
817     application is GUI based. Instead, you should include the ibexpressconsolemode package.
818 tony 31
819     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
820     to use the built in dialogs and cursor management. IBDialogs is
821 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
822 tony 31 This should be the case for all projects created through the IDE. This is why
823     you do not want to add the ibexpress package to console mode applications. The
824     ibexpressconsolemode package has been created to allow console mode programs
825     to avoid adding LCL dependencies when using IBX, while still having the
826     unit search paths set up correctly.
827    
828 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
829     each project's source file (*.lpr).
830    
831 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
832     exists, you have to first open the package in the IDE and then close it. This
833     adds it to the most recently accessed packages list. To make it permanently
834     available, add the package name to lazarus' staticpackages.inc file.
835    
836 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
837 tony 31
838     7. SQL Parser can now accept quoted strings that include new lines
839    
840     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
841     of text on start of edit. This is particularly useful when tabbing to a
842     column and then inserting text.
843    
844     9. New Examples provided for IB Services and ISQLMonitor.
845    
846     10. Fix error when writing to blob streams that recorded only the last buffer
847     write in the blob stream. In most cases, this did not cause a problem as the
848     IB Blob Stream is written in a single write. However, with the TDBImage, write
849     of a graphic type prefix was lost which caused a problem when the image could
850     not be automatically recognised.
851    
852     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
853 tony 33 already open" errors due to random numbers used for the cursor name being identical.
854 tony 31
855     12. IBTable: corrected error that could result in an "Index out of bounds" error
856     when opening the table and the Primary Key is the last or only column in the
857     table. Thanks to Rick Hoover for the fix.
858    
859 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
860     of "UTF-8", and update list of available database character sets. Existing
861     users should check the current lc_ctype setting in their applications.

863 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
864    
865 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
866     empty Params property.
867    
868     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
869     Link now set up in Loaded method - avoids occasional failure to apply
870     SQL markup on initial open.
871    
872     3. "Employees" example performance improvements when scrolling.
873    
874     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
875     TFrame. Force recaching of selected frame to avoid GTK race (results in a
876     random image cached).
877    
878     5. DBControlGrid: Should now react to changes in panel height at run time.
879    
880     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
881     even when further rows exist.
882    
883     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
884     always be derived from panel height and setting this property can cause confusion.
885     Note for existing projects: to avoid a missing property error at run time,
886     each form using the DBControlGrid must be opened, updated and saved in the IDE
887     in order to remove the property value from the lfm.
888    
889    
890 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
891 tony 27
892     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
893     call Prepare before setting parameter values.
894    
895     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
896    
897     3. Code tidyup and more robust handling of dsql information result vector.
898    
899     4. Support for centralised handling of transaction status changes. TIBTransaction
900     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
901     and "AfterExecQuery". The first three are called after the same event is called
902     for an IBCustomDataSet descendent using the Transaction. The fourth is called
903     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
904     enable monitoring of transaction status changes for a given transaction to be
905     handled in a single place. For example, when a change to the dataset occurs
906     an indicator can be set that shows the user that in order to save changes,
907     the transaction should be committed. Rather than doing this per dataset, this
908     can now be done per transaction.
909    
910     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
911     the dataset is scrolled. However, any changes to the current row are, by default,
912     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
913     have a new property "DataSetCloseAction" that adds automatic posting of changes
914     on dataset close. If this property is set to dcDiscardChanges (default) then the
915     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
916     then IBX will attempt to post any unsaved changes before the dataset is closed
917     (and after the BeforeClose event handler is called). The exception is when the
918     dataset is being closed as a result of a transaction rollback. In this case,
919     no action is taken and any unsaved changes are discarded. This avoids both
920     unnecessary overhead and the risk that a validation error may occur in the Post
921     raising an exception and thereby preventing a rollback.
922    
923     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
924     In earlier versions, the Display Width was set to the maximum byte width rather than the character
925     width. Display Widths are now corrected by dividing by the max byte width per character.
926     For UTF8 character sets, the byte width is four and hence the Display Width will be
927     the byte width divided by 4. The byte width of each character set is determined
928     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
929     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
930    
931     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
932    
933     8. IBLookupComboEditBox: List should now always be restored to full list when the
934     control loses focus. Default Key press default interval reduced to 200ms.
935    
936     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
937     when dataset rows are less than visible rows.
938    
939     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
940     does not exist or DataSet is empty. More responsive on dataset open. New event
941     OnRestorePosition. Column sort disabled if no header row.
942    
943     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
944     while dataset state is dsInsert. Avoids posting errors.
945    
946     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
947     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
948    
949     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
950    
951     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
952     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
953     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
954     always "posts" the current record regardless or whether or not it may be more appropriate
955     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
956     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
957     as the first action of the "Post" method and allows the handler to convert the Post
958     into a Cancel if that is the appropriate action on moving to a different row. This is
959     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
960     raised here, but it may still be more appropriate to validate a post and signal
961     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
962    
963     15. On Unix derived systems, the Firebird library name can now be given as a colon
964     separated list. Each library name on the list is tried in turn, in left to right
965     order with the first found being used as the firebird library. By default, on Linux,
966     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
967     overidden by the FBLIB environment variable or the OnGetLibraryName function.
968    
969     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
970     then it will still attempt to access the database via the Firebird Server and will
971     require a username and password. If only the pathname is given, then the username
972     and password should be omitted and the unix file permissions are used to grant
973     access.

976 tony 23
977     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
978     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
979     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
980 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
981 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
982    
983     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
984 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
985 tony 23 takes place during database access. This may be useful when there are performance issues with
986     the change of cursor. Setting the property to false suppresses the change of cursor.
987    
988     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
989     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
990     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
991     making all changes permanent immediately rather than when the transaction is explicitly
992     committed.
993    
994 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
995 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

1002 tony 21
1003     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1004     This is typically used during an "OnBeforeOpen" event handler to manipulate the
1005     "Where" and "Having" clauses to implement user specified filters of arbitrary
1006     complexity.
1007    
1008     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1009     three new data aware controls dependent on IBX and which make use of the SQL Parser.
1010     These are:
1011    
1012     - TIBLookupComboEditBox
1013     - TIBDynamicGrid
1014     - TIBTreeview
1015    
1016     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1017     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1018     to revise the available list and restrict it to items that are prefixed by the
1019 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
1020 tony 21 newly typed entry to be added to the list dataset and included in the available
1021     list items.
1022    
1023     TIBDynamicGrid is a TDBGrid descendent that provides for:
1024     - automatic resizing of selected columns to fill the available row length
1025     - automatic positioning and sizing of a "totals" control, typically at the
1026     column footer, on a per column basis.
1027     - DataSet resorting on header row click, sorting the dataset by the selected column.
1028     A second click on the same header cell reversed the sort order.
1029     - Support for a "Panel Editor". That is on clicking the indicator column, the row
1030     is automatically expanded and a panel superimposed on it. The panel can have any
1031     number of child controls, typically data aware controls with the same datasource
1032     as the grid allowing for editing of additional fields and more complex editors.
1033     - Reselection of the same row following resorting.
1034     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1035     Its properties are specified on a per column basis and allows for one or more
1036     columns to have their values selected from a list provided by a dataset.
1037     Autocomplete and autoinsert are also available. The existing picklist editor
1038     is unaffected by the extension.
1039    
1040     TIBTreeView is a data aware TCustomTreeView.
1041    
1042     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1043     zero scale will no longer return an error. An Int64 will be returned instead.
1044    
1045     4. TIBTransaction now has events for Before and After Transaction End and a new function
1046     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1047    
1048     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1049     repeated multiple times.
1050    
1051     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1052     check used to get in the way of using Stored Procedures, and "Update or Insert"
1053     statements.
1054    
1055     7. Insert, Modify and Delete property Editors now support Query Generation from
1056     Stored Procedures.
1057    
1058     8. Three new examples illustrate the use of the new IB Controls
1059

1062 tony 19
1063     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1064     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1065     Gabor Boros for reporting this problem and for testing the improvements).
1066    
1067     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1068     See readme.field+param.names in the doc folder.
1069    
1070     3. IBX SQL Editors will now automatically add double quotes around column names when the database
1071     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1072    
1073     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1074    
1075     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1076     actions.
1077    
1078     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1079     thanks to Yuriy Kopnin for pointing this out).
1080    
1081     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1082    
1083     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1084     for both fields and parameter setting.
1085    
1086     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1087     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1088    
1089     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1090     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1091    
1092     11. TIBTable now has a property editor for "MasterFields"
1093    
1094     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1095     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1096    
1097     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1098     of settings is unrecognised. Selecting this radio button has no effect on the settings.
1099

1106    
1107     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1108     it is null. This allows for alternative user defined setting of the generator
1109    
1110     Many thanks to Julio Jiménez for this fix
1111    
1112     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1113     and suggests that the user may have forgotten to install it.
1114    
1115 tony 13 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1116    
1117     1. Conditional compilation used to limit registration of TIntegerField to
1118     Lazarus versions less than 1.1
1119    
1120     2. When a database connection is created, character set is now by default set
1121     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1122     1250 to 1254.

1131 tony 7
1132     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1133     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1134    
1135     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1136     package is changed to do this (which it should do).
1137    
1138     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1139    
1140     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1141    
1142     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1143    
1144     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1145    
1146     4. Property editors should now correctly resize.
1147    
1148     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1149     (restored original functionality)
1150    
1151     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1152     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
