1 tony 267 IBX Change Log version (2.3-3 Build 11288) Fri, 28 Dec 2018 10:04:17 +0000
2 tony 266
3 tony 267 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
4     and is used to override the default settings in the client side "firebird.conf" This
5     includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
6     Each line of the string list should be a setting in the same format as "firebird.conf".
7     For example "WireCompression = true" in order to request wire compression on the client side.
8 tony 266
9 tony 267 Note: explicit settings in the client side "firebird.conf" appear to take precedence
10     over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
11     also require a compatible setting in the server side "firebird.conf". For example
12     "WireCompression = true" must also be set in the server's "firebird.conf" for wire
13     compression to be used.
14 tony 266
15 tony 267 Whether or not WireCompression or WireCrypt are in use can be checked using the information
16     returned with the Client/Server protocol version. See ibx/examples/dbadmin and
17     ibx/examples/dbinfo for examples of how to display this information.
18 tony 263
19 tony 267 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
20     is a "convenience" property. If set the "WireCompression=true" is added to the
21     ConfigOverrides. If unchecked then this setting is removed.
22    
23     IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
24    
25 tony 263 1. Remove need to check for IsMultiThread by providing access to GUI timers via
26     IBGUIInterface. Note: master/detail delay timer does not apply to console
27     mode apps.
28    
29     2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
30     statement. This avoids problems if "Execute Block" is used as the Query.
31    
32     3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
33     internal SQL tokeniser routines.
34    
35     4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
36     as a select statement, with or without CTEs.
37    
38     5. IBSQLParser: parser now recognises the "ROWS" clause.
39    
40     6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
41     internal SQL tokeniser routines.
42    
43     7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
44     being raised for valid set statements processed by a data formatter.
45    
46     8. New published property for TIBDatabase and TIBXServicesConnection. This is
47     FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
48     the path of the Firebird Library used by the database/services connection.
49    
50     9. New read only public property for TIBDatabase and TIBXServicesConnection. This
51     is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
52     services connection.
53    
54     10.SQL Property editors now quote parameter names if "Quote identifier" is selected
55     or param name is not a valid SQL identifier.
56    
57     11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
58     view of whether the text box should be editable when no DataSource is specified.
59     TIBLookupComboEditBox has been updated to workaround this problem. As long as
60     ReadOnly is false, the text box is editable when no DataSource is specified.
61    
62     12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
63     the FBLIB environment variable. If you do not want to permit this then you
64     must modify the Register procedure in the design/IBDBReg.pas unit to remove
65     this setting.
66    
67 tony 241 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
68    
69     1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
70     Utf8EscapeControlChars
71    
72 tony 232 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
73 tony 101
74 tony 209 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
75     all previous copies of the IBX source code tree before installing this release.
76    
77     The IBX packages used by most users have not changed, with one exception. The
78     IBServices unit has been moved to the package iblegacyServices.lpk. To continue
79     to use the IBServices unit in your applications, please add the iblegacyServices
80     to the list of dependencies. To do this, open the Project Inspector and select
81     Add->New Requirement and select "ibLegacyServices" from the list of available
82     packages.
83    
84     1. New unit IBXServices. The IBXServices unit is a re-architectured update of
85     the IBServices unit providing what is intended to be a clearer and easier to
86     use set of IB Services components. See Chapter 10 of the IBX User Guide for
87     more information and the guide to "Firebird Service Management Using IBX".
88     As indicated above, the legacy services components are still available and
89     provided in a separate package. There is no need to update working applications
90     using the older versions except for an additional package dependency.
91    
92     2. The IBX packages and source code tree have been re-organised in an attempt to
93     finally get rid of the "duplicate ppu" warnings. This re-organisation should
94     not affect existing users. Section 2.3 of the IBX User Guide describes the
95     new set of IBX packages.
96    
97     3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
98     updated to use the new Services API components.
99    
100     4. The iblocal package has been updated to use the new Services API components.
101    
102     5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
103     TIBXSecurityService. It had been wrongly classified in the previous version
104     as a per database configuration item. It is global to a server and hence
105     correctly positioned as part of the Security Package. In the DBAdmin example,
106     the setting has moved to the mappings page.
107    
108     6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
109     are ignored.
110    
111     7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
112     closed before the database is dropped. Before and After Disconnect event handlers
113     are also fired.
114    
115     8. TIBTransaction: OnStartTransaction event now fires every time the transaction
116     is started and not just the first time.
117    
118     9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
119     depenendency with comp type.
120    
121     10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
122    
123     11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
124     then this is recognised and not ignored.
125    
126     12. TIBDataSet, TIBQuery, TIBTable: additions:
127     function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
128     function GetPerfStatistics(var stats: TPerfCounters): boolean;
129     property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
130    
131     GetRowsAffected returns the affected row counts from the last insert/update/delete
132     if EnableStatistics = true then GetPerfStatistics returns the current stats
133     counters for the select query. Note: stats accumulate after each fetch from
134     the database. To get total query cost after open, call the "Last" method
135     and then GetPerfStatistics.
136    
137     See ibx/examples/consolemode for an example of the use of GetPerfStatistics
138    
139     13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
140     in parenthesises.
141    
142     14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
143     SQL identifiers are always delimited by double quotes. If false, then they are
144     only delimited if the identifier is a reserved word, contains lower case or special
145     characters. Set this property to true to retain previous behaviour.
146    
147     15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
148     are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
149    
150     16. TIBDataSet, TIBQuery, TIBTable: addition:
151     property MasterDetailDelay: integer {defaults to zero}
152    
153     When non-zero and the dataset is a detail table referencing a master table
154     through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
155     then a synchronisation delay is added (in milliseconds) between the master
156     row changing and the detail dataset being re-opened. If the master dataset
157     is scrolled before the delay expires then the delay is reset. This can be used
158     to avoid performance overheads when scrolling through a large master dataset.
159    
160     Note: uses fptimer and hence requires a thread manager. Under Linux the
161     chreads unit must be included in your project. TTimer is not used in order
162 tony 213 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
163 tony 209
164     17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
165     with Extract Option eoDatabase.
166    
167     18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
168 tony 225 When a deLayoutChanged event is reported on the ListSource dataset, the
169 tony 209 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
170     relationship with the control's datasource (master).
171    
172 tony 221 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
173    
174 tony 226 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
175 tony 221 stubs. Pedantic fix really, as procedures output in dependency order anyway.
176    
177 tony 226 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
178 tony 221 DDL (Firebird 3 and later only).
179    
180 tony 225 22. TIBLookupComboBox Autocomplete Fixes:
181     i. Only appended text is now selected after autocomplete.
182     ii. Uppercase keys no longer ignored for autocomplete.
183     iii. Retain Prefix case is now honoured correctly.
184     iv. When a DataSource is assigned, typing after autocomplete now extends prefix
185     before autocomplete performed. i.e. behaviour now the same as when
186     no DataSource assigned.
187    
188 tony 226 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
189 tony 225 between SQL statements.
190    
191     24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
192     ObjectNames are converted to upper case before matching against metadata object
193     names, unless the objectname is delimited by double quotes, in which case, the
194     double quotes are removed and the remaining string is used (unmodified) to match
195     against the metadata object name.
196    
197     If true then the ObjectName is used as is without modification and matched
198     against the metadata object name. No attempt is made to remove double quotes.
199    
200 tony 226 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
201     with eoTrigger, these extract types can be used to select only Database Triggers,
202     or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
203    
204 tony 227 26. TIBXScript: If an exception occurs during the processing of a statement, the
205     statement separate character is now reset to the default (';').
206    
207 tony 229 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
208    
209     28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
210     a commit or reconnect statement and instead activated only when next SQL statement
211     is executed.
212    
213     29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
214    
215     30. TIBXScript: case insensitive regex now used when matching statements instead of
216     converting statement to upper case.
217    
218     31. TIBExtract: metadata comments now supported. New published property
219     IncludeMetaDataComments (default true). If true then metadata comments included
220     in extracted DDL. New Extract Object member eoComments. This may be used with
221     ExtractObject method to list all metadata comments.
222    
223     32. TIBExtract: ListObjectNames method added.
224    
225 tony 231 33. Updated Database component editor to support additional connection string
226     types.
227    
228 tony 209 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
229    
230 tony 151 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
231 tony 152 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
232 tony 151 RELEASE.
233    
234     NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
235    
236 tony 107 1. IBExtract: Identity columns - add additional check for null column for generator name.
237 tony 101
238     2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
239     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
240 tony 107 information). However, this is also a very useful mechanism for returning updated computed by
241     column values. Values returned as a result of executing an Insert or Update statement
242     replace existing values in the current row for each corresponding column.
243 tony 101
244 tony 107 Previously, if a dataset's select query included read only (computed by) fields then
245     an automatic row refresh was performed after an insert or update query had been processed,
246     irrespective of the setting of the "ForcedUpdates" property. This has changed such
247     that an automatic refresh is no longer performed if an insert or update query contains
248     a returning clause that updates one or more fields on the current row. A full row
249     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
250     field values and the select query contains read only fields. Use of Insert/update
251 tony 123 returning should be significantly more efficient than executing a refresh query.
252 tony 107
253     This behaviour change is intended to be backwards compatible and there should be no need to change
254     existing programs, other than to improve performance by using the new capability.
255    
256 tony 118 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
257     they are called when the dataset row is being deleted, there is no value in
258     updating the current record from the query result. Instead, a new event handler
259     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
260     an OnDeleteReturning event handler is provided then it is called with the IResults returned
261     by the query. The event handler can then interrogate the query results and
262     perform whatever action is necessary. For example to confirm, to the user,
263     the deletion of a row with the returned values.
264    
265     4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
266 tony 107 any Computed By or Identity Columns. The IBTables example has been updated to
267     illustrate the computation of the employee Full Name on update.
268    
269 tony 118 5. TIBTable: The GeneratorField property is now published.
270 tony 107
271 tony 118 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
272 tony 101 When InsertSQL is generated, the Identity columns are not included in the list of values to
273     be inserted. A RETURNING clause is added to the insert statement to return the value of
274     each Identity column after the insert is executed.
275    
276 tony 118 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
277 tony 107 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
278     Insert..Returning clause.
279 tony 104
280 tony 118 8. TIBGenerator: small performance improvement by not preparing query each time
281 tony 107 a new value is generated.
282 tony 104
283 tony 118 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
284 tony 107
285 tony 118 10. Property editors will now sync table name to a System Table when "Include System
286     Tables" is selected and the query is for a System Table.
287 tony 105
288 tony 118 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
289 tony 107 values are no longer converted to milliseconds from TDateTime and then back again
290     to TDateTime (the conversion to milliseconds is the default TDataset approach).
291 tony 105
292 tony 118 12. Property Editors handling of Stored Procedures.
293 tony 107 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
294     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
295     query).
296     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
297 tony 106
298 tony 118 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
299 tony 107 can be used to select a package. If non-empty, the stored procedure name is
300     expected to be a stored procedure defined in the specified package and the
301     generated SQL will be as required for a stored procedure located in a package.
302    
303 tony 118 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
304 tony 107 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
305     which a stored procedure can be selected. With no package name selected, non-package
306     stored procedures are listed.
307    
308 tony 118 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
309 tony 109 for password on reconnect.
310 tony 107
311 tony 143 16. TIBDatabase: use IAttachment for connection default character set id, code page
312 tony 118 and character set name.
313 tony 109
314 tony 118 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
315     DB info lookups"
316    
317 tony 143 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
318 tony 118
319 tony 127 19. Add a property Editor for TIBUpdate.RefreshSQL.
320 tony 118
321 tony 139 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
322     parameters. This stops an exception being raised when the field cannot be
323     located in the record buffer.
324 tony 127
325 tony 141 21. Property Editors now automatically include System Tables when opened and when the query table
326     is a System Table.
327 tony 139
328 tony 150 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
329 tony 143 This avoids errors due to a stale SQRB or SRB being used for the next query.
330 tony 141
331 tony 143 23. IBServices: Service attach parameters now include "expected_db". This is used to
332     add the SPB item isc_spb_expected_db. This names a database using
333     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
334     database. examples/services re-written to illustrate use of "expected_db".
335 tony 141
336 tony 143 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
337     This avoids truncated backups when the server returns a timeout (busy) response.
338    
339     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
340    
341     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
342     databasenames. These are respectively expanded to the local system's temp directory
343 tony 150 (including trailing delimiter) or to a prescribed data directory (including
344 tony 143 trailing delimiter). Under Unix systems the data directory is a hidden directory
345     in the user's home directory. The hidden directory name is either the string returned
346     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
347     Under Windows, the directory is the same as the Data Directory as decribed
348     above but instead prefixed by the User's application data path. These may be
349 tony 150 used to improve application portability for Personal Databases.
350 tony 143
351     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
352     this has not worked for a long time and is not useful either. FieldDefs should be
353     managed using the Fields Editor as with any other dataset. To access the fields
354     editor for a TIBTable component, double click on the component. The fields editor
355     is then displayed.
356    
357     28. TIBDatabaseInfo: new properties/function
358     * DateDBCreated (returns date/time database created)
359     * TransactionCount (returns no. of active transactions)
360     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
361     * PagesFree (Firebird 3 or later)
362     * PagesUsed (Firebird 3 or later)
363     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
364     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
365    
366     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
367    
368     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
369    
370     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
371     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
372    
373     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
374     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
375     firing during backup and restore.
376    
377     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
378     for verbose output using the new property "StatisticsRequested".
379     see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
380    
381     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
382    
383     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
384     palette. This uses the online validation feature added in Firebird 2.5. The
385     services's properties enable inclusion/exclusion of tables and indexes using
386     regular expressions. See.
387     https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
388    
389     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
390     option on a database.
391    
392     37. TIBCustomService: Assign method implemented to allow copying of service login
393     context between service API components. "Detach" method now only detaches
394     service when last reference to the service interface detaches. Tidy up of
395     code for SetActive and Attach methods including password hiding.
396    
397 tony 150 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
398 tony 143 and used to determine the auth method and protocol used for the connection.
399    
400     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
401     a Create Database Statement generated by IBX.
402    
403     40. All IBServices now have an additional published property "PortNo". This may
404     be set to a non-standard port number when necessary. If zero then the default
405     port number is used.
406    
407     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
408     and not just the mouse.
409    
410     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
411    
412     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
413     image index and selected image index for each node to be set from a database field.
414    
415     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
416     then database schema includes grants to all users. If not present then the
417     only user grants included are those to User PUBLIC.
418    
419     45. TIBTreeView: performance improvement. When expanding include both expanded node
420     and child nodes in dataset.
421

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

809 tony 31
810     1. OnCloseUp Event Handler added to TDBLookupProperties
811    
812     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
813     problem with row size when exception is called.
814    
815     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
816    
817     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
818     in a TCustomComboBox and ignores return key if in a TCustomMemo
819    
820     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
821     keyed in i.e. when autocomplete not performed
822    
823 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
824     console mode applications with all LCL required functions (builtin dialogs and
825     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
826     not included in your project, IBX should compile and link with a console mode program.
827     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
828     console mode application or the IDE will automatically assume that your
829     application is GUI based. Instead, you should include the ibexpressconsolemode package.
830 tony 31
831     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
832     to use the built in dialogs and cursor management. IBDialogs is
833 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
834 tony 31 This should be the case for all projects created through the IDE. This is why
835     you do not want to add the ibexpress package to console mode applications. The
836     ibexpressconsolemode package has been created to allow console mode programs
837     to avoid adding LCL dependencies when using IBX, while still having the
838     unit search paths set up correctly.
839    
840 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
841     each project's source file (*.lpr).
842    
843 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
844     exists, you have to first open the package in the IDE and then close it. This
845     adds it to the most recently accessed packages list. To make it permanently
846     available, add the package name to lazarus' staticpackages.inc file.
847    
848 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
849 tony 31
850     7. SQL Parser can now accept quoted strings that include new lines
851    
852     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
853     of text on start of edit. This is particularly useful when tabbing to a
854     column and then inserting text.
855    
856     9. New Examples provided for IB Services and ISQLMonitor.
857    
858     10. Fix error when writing to blob streams that recorded only the last buffer
859     write in the blob stream. In most cases, this did not cause a problem as the
860     IB Blob Stream is written in a single write. However, with the TDBImage, write
861     of a graphic type prefix was lost which caused a problem when the image could
862     not be automatically recognised.
863    
864     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
865 tony 33 already open" errors due to random numbers used for the cursor name being identical.
866 tony 31
867     12. IBTable: corrected error that could result in an "Index out of bounds" error
868     when opening the table and the Primary Key is the last or only column in the
869     table. Thanks to Rick Hoover for the fix.
870    
871 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
872     of "UTF-8", and update list of available database character sets. Existing
873     users should check the current lc_ctype setting in their applications.

875 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
876    
877 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
878     empty Params property.
879    
880     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
881     Link now set up in Loaded method - avoids occasional failure to apply
882     SQL markup on initial open.
883    
884     3. "Employees" example performance improvements when scrolling.
885    
886     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
887     TFrame. Force recaching of selected frame to avoid GTK race (results in a
888     random image cached).
889    
890     5. DBControlGrid: Should now react to changes in panel height at run time.
891    
892     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
893     even when further rows exist.
894    
895     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
896     always be derived from panel height and setting this property can cause confusion.
897     Note for existing projects: to avoid a missing property error at run time,
898     each form using the DBControlGrid must be opened, updated and saved in the IDE
899     in order to remove the property value from the lfm.
900    
901    
902 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
903 tony 27
904     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
905     call Prepare before setting parameter values.
906    
907     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
908    
909     3. Code tidyup and more robust handling of dsql information result vector.
910    
911     4. Support for centralised handling of transaction status changes. TIBTransaction
912     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
913     and "AfterExecQuery". The first three are called after the same event is called
914     for an IBCustomDataSet descendent using the Transaction. The fourth is called
915     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
916     enable monitoring of transaction status changes for a given transaction to be
917     handled in a single place. For example, when a change to the dataset occurs
918     an indicator can be set that shows the user that in order to save changes,
919     the transaction should be committed. Rather than doing this per dataset, this
920     can now be done per transaction.
921    
922     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
923     the dataset is scrolled. However, any changes to the current row are, by default,
924     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
925     have a new property "DataSetCloseAction" that adds automatic posting of changes
926     on dataset close. If this property is set to dcDiscardChanges (default) then the
927     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
928     then IBX will attempt to post any unsaved changes before the dataset is closed
929     (and after the BeforeClose event handler is called). The exception is when the
930     dataset is being closed as a result of a transaction rollback. In this case,
931     no action is taken and any unsaved changes are discarded. This avoids both
932     unnecessary overhead and the risk that a validation error may occur in the Post
933     raising an exception and thereby preventing a rollback.
934    
935     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
936     In earlier versions, the Display Width was set to the maximum byte width rather than the character
937     width. Display Widths are now corrected by dividing by the max byte width per character.
938     For UTF8 character sets, the byte width is four and hence the Display Width will be
939     the byte width divided by 4. The byte width of each character set is determined
940     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
941     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
942    
943     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
944    
945     8. IBLookupComboEditBox: List should now always be restored to full list when the
946     control loses focus. Default Key press default interval reduced to 200ms.
947    
948     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
949     when dataset rows are less than visible rows.
950    
951     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
952     does not exist or DataSet is empty. More responsive on dataset open. New event
953     OnRestorePosition. Column sort disabled if no header row.
954    
955     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
956     while dataset state is dsInsert. Avoids posting errors.
957    
958     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
959     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
960    
961     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
962    
963     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
964     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
965     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
966     always "posts" the current record regardless or whether or not it may be more appropriate
967     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
968     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
969     as the first action of the "Post" method and allows the handler to convert the Post
970     into a Cancel if that is the appropriate action on moving to a different row. This is
971     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
972     raised here, but it may still be more appropriate to validate a post and signal
973     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
974    
975     15. On Unix derived systems, the Firebird library name can now be given as a colon
976     separated list. Each library name on the list is tried in turn, in left to right
977     order with the first found being used as the firebird library. By default, on Linux,
978     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
979     overidden by the FBLIB environment variable or the OnGetLibraryName function.
980    
981     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
982     then it will still attempt to access the database via the Firebird Server and will
983     require a username and password. If only the pathname is given, then the username
984     and password should be omitted and the unix file permissions are used to grant
985     access.

988 tony 23
989     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
990     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
991     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
992 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
993 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
994    
995     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
996 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
997 tony 23 takes place during database access. This may be useful when there are performance issues with
998     the change of cursor. Setting the property to false suppresses the change of cursor.
999    
1000     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1001     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1002     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1003     making all changes permanent immediately rather than when the transaction is explicitly
1004     committed.
1005    
1006 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1007 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

1014 tony 21
1015     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1016     This is typically used during an "OnBeforeOpen" event handler to manipulate the
1017     "Where" and "Having" clauses to implement user specified filters of arbitrary
1018     complexity.
1019    
1020     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1021     three new data aware controls dependent on IBX and which make use of the SQL Parser.
1022     These are:
1023    
1024     - TIBLookupComboEditBox
1025     - TIBDynamicGrid
1026     - TIBTreeview
1027    
1028     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1029     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1030     to revise the available list and restrict it to items that are prefixed by the
1031 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
1032 tony 21 newly typed entry to be added to the list dataset and included in the available
1033     list items.
1034    
1035     TIBDynamicGrid is a TDBGrid descendent that provides for:
1036     - automatic resizing of selected columns to fill the available row length
1037     - automatic positioning and sizing of a "totals" control, typically at the
1038     column footer, on a per column basis.
1039     - DataSet resorting on header row click, sorting the dataset by the selected column.
1040     A second click on the same header cell reversed the sort order.
1041     - Support for a "Panel Editor". That is on clicking the indicator column, the row
1042     is automatically expanded and a panel superimposed on it. The panel can have any
1043     number of child controls, typically data aware controls with the same datasource
1044     as the grid allowing for editing of additional fields and more complex editors.
1045     - Reselection of the same row following resorting.
1046     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1047     Its properties are specified on a per column basis and allows for one or more
1048     columns to have their values selected from a list provided by a dataset.
1049     Autocomplete and autoinsert are also available. The existing picklist editor
1050     is unaffected by the extension.
1051    
1052     TIBTreeView is a data aware TCustomTreeView.
1053    
1054     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1055     zero scale will no longer return an error. An Int64 will be returned instead.
1056    
1057     4. TIBTransaction now has events for Before and After Transaction End and a new function
1058     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1059    
1060     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1061     repeated multiple times.
1062    
1063     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1064     check used to get in the way of using Stored Procedures, and "Update or Insert"
1065     statements.
1066    
1067     7. Insert, Modify and Delete property Editors now support Query Generation from
1068     Stored Procedures.
1069    
1070     8. Three new examples illustrate the use of the new IB Controls
1071    
1072    
1073 tony 33 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1074 tony 19
1075     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1076     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1077     Gabor Boros for reporting this problem and for testing the improvements).
1078    
1079     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1080     See readme.field+param.names in the doc folder.
1081    
1082     3. IBX SQL Editors will now automatically add double quotes around column names when the database
1083     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1084    
1085     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1086    
1087     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1088     actions.
1089    
1090     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1091     thanks to Yuriy Kopnin for pointing this out).
1092    
1093     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1094    
1095     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1096     for both fields and parameter setting.
1097    
1098     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1099     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1100    
1101     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1102     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1103    
1104     11. TIBTable now has a property editor for "MasterFields"
1105    
1106     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1107     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1108    
1109     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1110     of settings is unrecognised. Selecting this radio button has no effect on the settings.
1111

1118    
1119     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1120     it is null. This allows for alternative user defined setting of the generator
1121    
1122     Many thanks to Julio Jiménez for this fix
1123    
1124     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1125     and suggests that the user may have forgotten to install it.
1126    
1127 tony 13 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1128    
1129     1. Conditional compilation used to limit registration of TIntegerField to
1130     Lazarus versions less than 1.1
1131    
1132     2. When a database connection is created, character set is now by default set
1133     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1134     1250 to 1254.

1143 tony 7
1144     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1145     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1146    
1147     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1148     package is changed to do this (which it should do).
1149    
1150     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1151    
1152     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1153    
1154     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1155    
1156     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1157    
1158     4. Property editors should now correctly resize.
1159    
1160     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1161     (restored original functionality)
1162    
1163     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1164     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
