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

401 tony 90 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
402 tony 56
403     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
404     changes.
405    
406 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
407     Bug could result in truncated multi-byte character set values.
408    
409 tony 60 3. Changes consequential on moving fbintf character set utility functions from
410     IFirebirdAPI to IAttachment.
411    
412 tony 62 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
413    
414 tony 64 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
415     results in autocomplete ignoring prefix text.
416    
417 tony 65 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
418     entering a new name into the text box.
419    
420 tony 66 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
421     Firebird rather than recomputing it.
422    
423 tony 67 8. Property Editor positioning tidy up: All IBX Property editors should now be
424     screen centre. Previously some were "poDesigned" which may be inappropriate
425     for multi monitor desktops.
426    
427 tony 80 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
428    
429     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
430     a transaction and always reset the object.
431    
432     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
433    
434     13. TIBXScript: Allow for override of database filename in Create Database statements.
435    
436     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
437     to a gbak format archive.
438    
439     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
440    
441     16. IBLocaldb: Drop database if error creating an empty database.
442    
443     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
444     unless selected node not in current dataset.
445    
446     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
447     to TIBCustomService, and IBlocalDB code tidy up.
448    
449     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
450     behaviour due to uninitialised variable.
451    
452     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
453     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
454    
455     21. IBSQL: When Database changed ensure that all resources are freed.
456    
457     22. IBCustomDataset: When database changed ensure that queries an unprepared.
458    
459 tony 84 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
460     * Line Wrap on SQL Token boundaries (on user command)
461     * auto-complete table names in drop down list of table names
462     * Double click on tablename or field name adds to SQL text
463 tony 80
464     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
465    
466     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
467     TVariantArray. Seems to avoid memory corruption in Windows (probably a
468     workaround for a problem in fpc 3.0.4 win64).
469    
470     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
471    
472 tony 83 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
473    
474 tony 51 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
475 tony 49
476 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
477 tony 49 include remote system name.
478    
479     2. TIBExtract: No longer include comment header and COMMIT statement for empty
480     tables when data included in output.
481    
482     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
483     and timing information to be written to stdout. This may be used to locate
484     performance bottlenecks.
485    
486     4. SQLParser: only call "OnChanging" event handler when value is different.
487    
488     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
489    
490 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
491     that BindFields is called when the query is next activated. Avoids FieldName
492     not found error.
493    
494 tony 80 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
495     purpose and allows the programmer to define any action they want for Update, Insert
496     or Delete. This may be complex SQL (similar to a Trigger), application specific
497     filtering of updates, or use of statements such as Grant or Revoke instead of
498     normal DML. See User Manual for more information.
499    
500 tony 47 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
501 tony 45
502 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
503 tony 45
504 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
505    
506     3. TIBExtract: data formatted as Charset set "octets" is now output using
507     hexadecimal notation.
508    
509     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
510     using a simple XML format.
511    
512     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
513     grants to these objects.
514    
515     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
516     dependency problems restoring complex databases.
517    
518     7. TIBXScript: This component has been restructured to allow for the processing of
519     embedded XML in INSERT statements and to support interactive sources in addition
520     to non-interactive data sources such as files.
521    
522     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
523    
524     9. TIBXScript: ISQL compatiable Set statements are now supported:
525     SET SQL DIALECT
526     SET TERM
527     SET AUTODDL
528     SET BAIL
529     SET ECHO
530     SET COUNT
531     SET STATS
532     SET NAMES <character set>
533    
534     10. IBVersion unit added to hold current IBX Version Number information.
535    
536     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
537     and domain definitions.
538    
539     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
540     fully supported.
541    
542     13. TIBExtract: when a database dump includes data, the generator values are now also set.
543    
544     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
545    
546     IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
547    
548 tony 50 See also doc/IBX4LazarusGuide.pdf for important information on
549 tony 45 upgrading to IBX2.
550    
551     1. Size property of TIBStringField is now the width in characters of the field
552     and not the byte length. This applies only to multi-byte character sets such
553     as UTF8. The original approach aligned with TStringField. However, the TStringField
554     code is not recognised as a bug and hence this change to align the behaviour.
555     The TStringField change is expected in fpc 3.2.0.
556    
557     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
558     true (default) then Size property value saved in the lfm is ignored. Size is
559     always set from the dynamic information read from the database. It is unclear
560     why anyone would want to override this and set Size to false.
561    
562     3. ibxscript: should now handle correctly a Case..End statement within a procedure
563     block.
564    
565     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
566     exist when an attempt is made to connect to it (run time only) then an attempt
567     is made to create the database.
568    
569     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
570     has been successfully created as a result of a call to CreateDatabase or when
571     creating a database after it was found not to exist.
572    
573     6. DBControlGrid: a race condition could result in the wrong row image being
574     written to the cache. This has been avoided by a trip round the message
575     loop before rendering the row image.
576    
577     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
578     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
579     known to risk corrupt rendering of row images when the control is first
580     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
581     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
582    
583     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
584     a TDateEdit control located on an editor panel.
585    
586     9. TIBExtract: brought up-to-date plus many bug fixes.
587    
588     10. DBControlGrid: Removed memory leak when updating rows.
589    
590     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
591    
592 tony 43 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
593    
594     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
595     when target codepage is CP_NONE. This is a workaround for
596     http://bugs.freepascal.org/view.php?id=30622.
597    
598     2. DBLog option removed from TIBStatisticalService - not supported by server
599     since Firebird 1.5.
600    
601     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
602     similar.
603    
604     4. IBCodePage: updated mapping between codepages and character id.
605    
606     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
607     Firebird. Character sets with a char width of two are not UTF16.
608    
609     6. Strings received from the database are now always transliterated into UTF8
610     regardless of the database character set or connection character set. This
611     is for compatibility with the LCL.
612    
613 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
614 tony 41
615     1. IBBlob: Defer reading of blob until read method called. This avoids having to
616     read in an entire blob just to get the size of the blob. General performance
617     improvement when opening datasets containing blobs.
618    
619     2. Clearing a Blob now sets the corresponding field's modified flag.
620    
621     3. IBLookupCombo: When not performing auto-complete, original query sort order
622     is now used.
623    
624     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
625     determined.
626    
627     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
628    
629     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
630     lazarus 1.6.0
631    
632     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
633     compilation error.
634    
635 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
636    
637     1. No character set specified for connection: when a text blob is retrieved, the
638     character set is determined by looking up the native character set using then
639     Firebird API. Otherwise a text mode blob is assumed to have the same character
640     set as the connection.
641    
642     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
643     for Login Dialog returing a change to the database path.
644    
645     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
646     to be changed from that given in the TIBDatabase/TIBServer component and for the
647     entered value to be saved on a project specific basis (design time only).
648    
649     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
650     column fieldname. If they are the same then it is acts as a look up for the KeyValue
651     Otherwise, it sets the column text to the selected ListField Value.
652    
653     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
654     column width.
655    
656     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
657     and a case insensitive search is requested.
658    
659     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
660     or column ListSource.
661    
662     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
663     unprepare) when closing and the text has not changed.
664    
665     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
666     Less likely to cause a cursor re-use error on Windows.
667    
668     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
669     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
670    
671     11. TIBTreeView: Guard against nil destination on record changed
672    
673     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
674     string type with the code page set to reflect the returned field encoding after
675     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
676     earlier versions.
677    
678     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
679     will now result in transliteration to the code page specified for the Firebird driver
680     if the assigned string has a different code page. FPC 3.0.0 onwards only.
681    
682     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
683     is ignored and the lc_ctype value, when the database is opened, is set to align with
684     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
685     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
686     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
687     the GETACP is used to determine the Windows code page.
688    
689     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
690     name used as the lc_ctype when the database was opened. Only valid while the
691     Database is connected.
692    
693     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
694     id that corresponds to the DefaultCharSetName.
695    
696 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
697    
698     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
699     path is given and database attach fails due to access permission issues on the
700     temp directory or security database, then the attach is retried with "localhost:"
701     prefixing the databasename. This should avoid problems when the database has to
702     be accessed by a local (e.g. classic) server and libfbembed is used.
703    
704     2. Windows: revised search order for Firebird DLL:
705     i. The Firebird Embedded Server in the application Directory.
706     ii. If the FIREBIRD environment variable is set then the directory this
707     points to is searched for the FB Client DLL and then then underlying
708     "bin" directory.
709     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
710     is used to locate the Firebird installation directory and the underlying
711     "bin" directory is searched for the FB Client DLL.
712     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
713     are searched for the FB Client DLL.
714     v. The PATH Environment variable is used to search for the FB Client DLL.
715     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
716    
717     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
718     See doc/readme.scriptengine and example applications.
719    
720     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
721     simplify the use of the embedded firebird server on both Linux and Windows platforms.
722     See dpc/readme.localdatabase and example applications.
723    
724     5. IBDynamicGrid: Reordering on column header click should now also work for
725     dynamic columns.
726    
727     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
728     between incrementing/decrementing the lock count and signalling the event.
729    
730 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
731    
732 tony 37 1.3.2 was never formally released and only made available as beta copies.
733    
734 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
735    
736     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
737    
738     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
739    
740     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
741     i.e. when it is a calculated field
742    
743     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
744     This problem was due to a race condition between recalculating row heights and
745     determining which row was selected by the mouse click. The row height calculation
746     is now deferred by an extra trip round the message loop allowing the row to
747     be always calculated on the current grid layout rather than risking it being
748     calculated on the grid layout after the expanded row has been shrunk.
749    
750     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
751     Windows.
752    
753     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
754     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
755 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
756 tony 35
757     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
758 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
759 tony 35
760     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
761     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
762 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
763 tony 35
764     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
765     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
766     implies no truncation.
767    
768     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
769    
770     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
771     (avoids "Not in Edit Mode" error).
772    
773     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
774    
775     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
776     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
777    
778     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
779    
780     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
781    
782     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
783    
784     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
785    
786 tony 33 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
787 tony 31
788     1. OnCloseUp Event Handler added to TDBLookupProperties
789    
790     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
791     problem with row size when exception is called.
792    
793     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
794    
795     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
796     in a TCustomComboBox and ignores return key if in a TCustomMemo
797    
798     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
799     keyed in i.e. when autocomplete not performed
800    
801 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
802     console mode applications with all LCL required functions (builtin dialogs and
803     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
804     not included in your project, IBX should compile and link with a console mode program.
805     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
806     console mode application or the IDE will automatically assume that your
807     application is GUI based. Instead, you should include the ibexpressconsolemode package.
808 tony 31
809     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
810     to use the built in dialogs and cursor management. IBDialogs is
811 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
812 tony 31 This should be the case for all projects created through the IDE. This is why
813     you do not want to add the ibexpress package to console mode applications. The
814     ibexpressconsolemode package has been created to allow console mode programs
815     to avoid adding LCL dependencies when using IBX, while still having the
816     unit search paths set up correctly.
817    
818 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
819     each project's source file (*.lpr).
820    
821 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
822     exists, you have to first open the package in the IDE and then close it. This
823     adds it to the most recently accessed packages list. To make it permanently
824     available, add the package name to lazarus' staticpackages.inc file.
825    
826 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
827 tony 31
828     7. SQL Parser can now accept quoted strings that include new lines
829    
830     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
831     of text on start of edit. This is particularly useful when tabbing to a
832     column and then inserting text.
833    
834     9. New Examples provided for IB Services and ISQLMonitor.
835    
836     10. Fix error when writing to blob streams that recorded only the last buffer
837     write in the blob stream. In most cases, this did not cause a problem as the
838     IB Blob Stream is written in a single write. However, with the TDBImage, write
839     of a graphic type prefix was lost which caused a problem when the image could
840     not be automatically recognised.
841    
842     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
843 tony 33 already open" errors due to random numbers used for the cursor name being identical.
844 tony 31
845     12. IBTable: corrected error that could result in an "Index out of bounds" error
846     when opening the table and the Primary Key is the last or only column in the
847     table. Thanks to Rick Hoover for the fix.
848    
849 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
850     of "UTF-8", and update list of available database character sets. Existing
851     users should check the current lc_ctype setting in their applications.

853 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
854    
855 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
856     empty Params property.
857    
858     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
859     Link now set up in Loaded method - avoids occasional failure to apply
860     SQL markup on initial open.
861    
862     3. "Employees" example performance improvements when scrolling.
863    
864     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
865     TFrame. Force recaching of selected frame to avoid GTK race (results in a
866     random image cached).
867    
868     5. DBControlGrid: Should now react to changes in panel height at run time.
869    
870     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
871     even when further rows exist.
872    
873     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
874     always be derived from panel height and setting this property can cause confusion.
875     Note for existing projects: to avoid a missing property error at run time,
876     each form using the DBControlGrid must be opened, updated and saved in the IDE
877     in order to remove the property value from the lfm.
878    
879    
880 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
881 tony 27
882     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
883     call Prepare before setting parameter values.
884    
885     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
886    
887     3. Code tidyup and more robust handling of dsql information result vector.
888    
889     4. Support for centralised handling of transaction status changes. TIBTransaction
890     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
891     and "AfterExecQuery". The first three are called after the same event is called
892     for an IBCustomDataSet descendent using the Transaction. The fourth is called
893     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
894     enable monitoring of transaction status changes for a given transaction to be
895     handled in a single place. For example, when a change to the dataset occurs
896     an indicator can be set that shows the user that in order to save changes,
897     the transaction should be committed. Rather than doing this per dataset, this
898     can now be done per transaction.
899    
900     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
901     the dataset is scrolled. However, any changes to the current row are, by default,
902     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
903     have a new property "DataSetCloseAction" that adds automatic posting of changes
904     on dataset close. If this property is set to dcDiscardChanges (default) then the
905     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
906     then IBX will attempt to post any unsaved changes before the dataset is closed
907     (and after the BeforeClose event handler is called). The exception is when the
908     dataset is being closed as a result of a transaction rollback. In this case,
909     no action is taken and any unsaved changes are discarded. This avoids both
910     unnecessary overhead and the risk that a validation error may occur in the Post
911     raising an exception and thereby preventing a rollback.
912    
913     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
914     In earlier versions, the Display Width was set to the maximum byte width rather than the character
915     width. Display Widths are now corrected by dividing by the max byte width per character.
916     For UTF8 character sets, the byte width is four and hence the Display Width will be
917     the byte width divided by 4. The byte width of each character set is determined
918     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
919     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
920    
921     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
922    
923     8. IBLookupComboEditBox: List should now always be restored to full list when the
924     control loses focus. Default Key press default interval reduced to 200ms.
925    
926     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
927     when dataset rows are less than visible rows.
928    
929     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
930     does not exist or DataSet is empty. More responsive on dataset open. New event
931     OnRestorePosition. Column sort disabled if no header row.
932    
933     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
934     while dataset state is dsInsert. Avoids posting errors.
935    
936     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
937     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
938    
939     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
940    
941     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
942     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
943     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
944     always "posts" the current record regardless or whether or not it may be more appropriate
945     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
946     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
947     as the first action of the "Post" method and allows the handler to convert the Post
948     into a Cancel if that is the appropriate action on moving to a different row. This is
949     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
950     raised here, but it may still be more appropriate to validate a post and signal
951     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
952    
953     15. On Unix derived systems, the Firebird library name can now be given as a colon
954     separated list. Each library name on the list is tried in turn, in left to right
955     order with the first found being used as the firebird library. By default, on Linux,
956     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
957     overidden by the FBLIB environment variable or the OnGetLibraryName function.
958    
959     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
960     then it will still attempt to access the database via the Firebird Server and will
961     require a username and password. If only the pathname is given, then the username
962     and password should be omitted and the unix file permissions are used to grant
963     access.

966 tony 23
967     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
968     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
969     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
970 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
971 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
972    
973     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
974 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
975 tony 23 takes place during database access. This may be useful when there are performance issues with
976     the change of cursor. Setting the property to false suppresses the change of cursor.
977    
978     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
979     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
980     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
981     making all changes permanent immediately rather than when the transaction is explicitly
982     committed.
983    
984 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
985 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

992 tony 21
993     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
994     This is typically used during an "OnBeforeOpen" event handler to manipulate the
995     "Where" and "Having" clauses to implement user specified filters of arbitrary
996     complexity.
997    
998     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
999     three new data aware controls dependent on IBX and which make use of the SQL Parser.
1000     These are:
1001    
1002     - TIBLookupComboEditBox
1003     - TIBDynamicGrid
1004     - TIBTreeview
1005    
1006     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1007     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1008     to revise the available list and restrict it to items that are prefixed by the
1009 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
1010 tony 21 newly typed entry to be added to the list dataset and included in the available
1011     list items.
1012    
1013     TIBDynamicGrid is a TDBGrid descendent that provides for:
1014     - automatic resizing of selected columns to fill the available row length
1015     - automatic positioning and sizing of a "totals" control, typically at the
1016     column footer, on a per column basis.
1017     - DataSet resorting on header row click, sorting the dataset by the selected column.
1018     A second click on the same header cell reversed the sort order.
1019     - Support for a "Panel Editor". That is on clicking the indicator column, the row
1020     is automatically expanded and a panel superimposed on it. The panel can have any
1021     number of child controls, typically data aware controls with the same datasource
1022     as the grid allowing for editing of additional fields and more complex editors.
1023     - Reselection of the same row following resorting.
1024     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1025     Its properties are specified on a per column basis and allows for one or more
1026     columns to have their values selected from a list provided by a dataset.
1027     Autocomplete and autoinsert are also available. The existing picklist editor
1028     is unaffected by the extension.
1029    
1030     TIBTreeView is a data aware TCustomTreeView.
1031    
1032     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1033     zero scale will no longer return an error. An Int64 will be returned instead.
1034    
1035     4. TIBTransaction now has events for Before and After Transaction End and a new function
1036     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1037    
1038     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1039     repeated multiple times.
1040    
1041     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1042     check used to get in the way of using Stored Procedures, and "Update or Insert"
1043     statements.
1044    
1045     7. Insert, Modify and Delete property Editors now support Query Generation from
1046     Stored Procedures.
1047    
1048     8. Three new examples illustrate the use of the new IB Controls
1049

1051 tony 33 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1052 tony 19
1053     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1054     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1055     Gabor Boros for reporting this problem and for testing the improvements).
1056    
1057     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1058     See readme.field+param.names in the doc folder.
1059    
1060     3. IBX SQL Editors will now automatically add double quotes around column names when the database
1061     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1062    
1063     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1064    
1065     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1066     actions.
1067    
1068     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1069     thanks to Yuriy Kopnin for pointing this out).
1070    
1071     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1072    
1073     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1074     for both fields and parameter setting.
1075    
1076     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1077     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1078    
1079     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1080     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1081    
1082     11. TIBTable now has a property editor for "MasterFields"
1083    
1084     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1085     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1086    
1087     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1088     of settings is unrecognised. Selecting this radio button has no effect on the settings.
1089

1096    
1097     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1098     it is null. This allows for alternative user defined setting of the generator
1099    
1100     Many thanks to Julio Jiménez for this fix
1101    
1102     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1103     and suggests that the user may have forgotten to install it.
1104    
1105 tony 13 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1106    
1107     1. Conditional compilation used to limit registration of TIntegerField to
1108     Lazarus versions less than 1.1
1109    
1110     2. When a database connection is created, character set is now by default set
1111     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1112     1250 to 1254.

1121 tony 7
1122     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1123     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1124    
1125     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1126     package is changed to do this (which it should do).
1127    
1128     IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1129    
1130     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1131    
1132     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1133    
1134     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1135    
1136     4. Property editors should now correctly resize.
1137    
1138     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1139     (restored original functionality)
1140    
1141     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1142     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
