1 tony 274 IBX Change Log version (2.3-3 Build 11493) Fri, 28 Dec 2018 10:04:17 +0000
2 tony 266
3 tony 272
4 tony 267 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
5     and is used to override the default settings in the client side "firebird.conf" This
6     includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
7     Each line of the string list should be a setting in the same format as "firebird.conf".
8     For example "WireCompression = true" in order to request wire compression on the client side.
9 tony 266
10 tony 267 Note: explicit settings in the client side "firebird.conf" appear to take precedence
11     over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
12     also require a compatible setting in the server side "firebird.conf". For example
13     "WireCompression = true" must also be set in the server's "firebird.conf" for wire
14     compression to be used.
15 tony 266
16 tony 267 Whether or not WireCompression or WireCrypt are in use can be checked using the information
17     returned with the Client/Server protocol version. See ibx/examples/dbadmin and
18     ibx/examples/dbinfo for examples of how to display this information.
19 tony 263
20 tony 267 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
21     is a "convenience" property. If set the "WireCompression=true" is added to the
22     ConfigOverrides. If unchecked then this setting is removed.
23    
24 tony 270 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
25     not "INT64".
26    
27     4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
28     These are:
29     property TimestampFormat: string;
30     property DateFormat: string;
31     property TimeFormat: string;
32    
33     Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
34     DATETIME and TIME. The format strings use the standard FPC date/time format
35     characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
36    
37     If any of the above properties are set to an empty string, then the locale default
38     is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
39     locale default is extended by appending '.zzz' to include milliseconds.
40    
41     TIBCSVDataOut by default sets these properties to the empty string, while the other
42     two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
43    
44     5. New published property for TIBCSVDataOut:
45     property QuoteStrings: boolean (default true)
46    
47     If false then strings are unquoted, otherwise, the QuoteChar property value is
48     used to delimit each and every string in the output.
49    
50     6. New published properties for TIBCSVDataOut:
51     property FieldSeparator: string;
52     property HeaderSeparator: string;
53    
54     Respectively, these provide the separator character(s) used to separate fields
55     in data and header rows. Both default to ','.
56    
57     7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
58     TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
59     property OnFormatTextString;
60    
61     This event handler can be used to process text strings before they are included
62     in the output e.g. to replace unprintable characters with alternative strings.
63     This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
64    
65     8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
66 tony 272 Uses "FindParam" if in order to find out if a parameter with a given name exists
67     and without raising and exception if it does not.
68 tony 270
69 tony 272 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
70 tony 270 consistency with SQL queries.
71    
72     10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
73     When true, SQL statement parameter names are parsed case sensitive. Note for
74     TIBDataSet only applies to Select query.
75    
76 tony 271 11. IBEvents: removing a TIBEvent component from a form should no longer result in
77     an IDE exception.
78    
79 tony 272 12. LocalDBSupport: initial database creation should now work correctly
80     when the schema source is an sql file.
81    
82     13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
83     when defined, this handler will be called by the internal TIBXScript during
84     initial database creation when the schema source is an sql file and may be used
85     to provide a visual indication of progress in console mode.
86    
87     14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
88     to true while a new local database is being created and its schema populated.
89     Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
90     when the database is disconnected/connected during the create DB procedure.
91    
92     15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
93     are now always ignored and replaced by the user name and password provided as
94     the login parameters for the TIBDatabase referenced from the TIBXScript. The
95     IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
96     completely ignored if this property is true.
97    
98     16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
99     to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
100     ImageIndex and SelectImageIndex values on AddNode.
101    
102     17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
103     read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
104     the same database connection.
105    
106     18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
107     if provided, this should be an conditional SQL expression suitable for
108     including in an SQL Select statement "where" clause. If non-empty and the
109     "Filtered" property is true then the SQL expression provided as the value of
110     the "Filter" property is "ANDed" with any existing condition statement
111     in the SQL statement's "Where" clause.
112    
113     If the "Filter" property is set at run time, the "Filtered" property is true
114     and the dataset is already open, then the dataset is closed and re-opened automatically.
115    
116     The "Filter" condition may include IBX style parameters. In which case, their
117     value must be set by the dataset's "OnBeforeOpen" event handler.
118    
119     This is a public property for TIBDataSet and TIBQuery query and intended for
120     use at run time.
121    
122     Note: The property is a published property of TIBTable. The TIBTable functionality
123     is unaffected by this change.
124    
125 tony 267 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
126    
127 tony 263 1. Remove need to check for IsMultiThread by providing access to GUI timers via
128     IBGUIInterface. Note: master/detail delay timer does not apply to console
129     mode apps.
130    
131     2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
132     statement. This avoids problems if "Execute Block" is used as the Query.
133    
134     3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
135     internal SQL tokeniser routines.
136    
137     4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
138     as a select statement, with or without CTEs.
139    
140     5. IBSQLParser: parser now recognises the "ROWS" clause.
141    
142     6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
143     internal SQL tokeniser routines.
144    
145     7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
146     being raised for valid set statements processed by a data formatter.
147    
148     8. New published property for TIBDatabase and TIBXServicesConnection. This is
149     FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
150     the path of the Firebird Library used by the database/services connection.
151    
152     9. New read only public property for TIBDatabase and TIBXServicesConnection. This
153     is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
154     services connection.
155    
156     10.SQL Property editors now quote parameter names if "Quote identifier" is selected
157     or param name is not a valid SQL identifier.
158    
159     11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
160     view of whether the text box should be editable when no DataSource is specified.
161     TIBLookupComboEditBox has been updated to workaround this problem. As long as
162     ReadOnly is false, the text box is editable when no DataSource is specified.
163    
164     12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
165     the FBLIB environment variable. If you do not want to permit this then you
166     must modify the Register procedure in the design/IBDBReg.pas unit to remove
167     this setting.
168    
169 tony 241 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
170    
171     1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
172     Utf8EscapeControlChars
173    
174 tony 232 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
175 tony 101
176 tony 209 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
177     all previous copies of the IBX source code tree before installing this release.
178    
179     The IBX packages used by most users have not changed, with one exception. The
180     IBServices unit has been moved to the package iblegacyServices.lpk. To continue
181     to use the IBServices unit in your applications, please add the iblegacyServices
182     to the list of dependencies. To do this, open the Project Inspector and select
183     Add->New Requirement and select "ibLegacyServices" from the list of available
184     packages.
185    
186     1. New unit IBXServices. The IBXServices unit is a re-architectured update of
187     the IBServices unit providing what is intended to be a clearer and easier to
188     use set of IB Services components. See Chapter 10 of the IBX User Guide for
189     more information and the guide to "Firebird Service Management Using IBX".
190     As indicated above, the legacy services components are still available and
191     provided in a separate package. There is no need to update working applications
192     using the older versions except for an additional package dependency.
193    
194     2. The IBX packages and source code tree have been re-organised in an attempt to
195     finally get rid of the "duplicate ppu" warnings. This re-organisation should
196     not affect existing users. Section 2.3 of the IBX User Guide describes the
197     new set of IBX packages.
198    
199     3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
200     updated to use the new Services API components.
201    
202     4. The iblocal package has been updated to use the new Services API components.
203    
204     5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
205     TIBXSecurityService. It had been wrongly classified in the previous version
206     as a per database configuration item. It is global to a server and hence
207     correctly positioned as part of the Security Package. In the DBAdmin example,
208     the setting has moved to the mappings page.
209    
210     6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
211     are ignored.
212    
213     7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
214     closed before the database is dropped. Before and After Disconnect event handlers
215     are also fired.
216    
217     8. TIBTransaction: OnStartTransaction event now fires every time the transaction
218     is started and not just the first time.
219    
220     9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
221     depenendency with comp type.
222    
223     10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
224    
225     11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
226     then this is recognised and not ignored.
227    
228     12. TIBDataSet, TIBQuery, TIBTable: additions:
229     function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
230     function GetPerfStatistics(var stats: TPerfCounters): boolean;
231     property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
232    
233     GetRowsAffected returns the affected row counts from the last insert/update/delete
234     if EnableStatistics = true then GetPerfStatistics returns the current stats
235     counters for the select query. Note: stats accumulate after each fetch from
236     the database. To get total query cost after open, call the "Last" method
237     and then GetPerfStatistics.
238    
239     See ibx/examples/consolemode for an example of the use of GetPerfStatistics
240    
241     13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
242     in parenthesises.
243    
244     14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
245     SQL identifiers are always delimited by double quotes. If false, then they are
246     only delimited if the identifier is a reserved word, contains lower case or special
247     characters. Set this property to true to retain previous behaviour.
248    
249     15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
250     are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
251    
252     16. TIBDataSet, TIBQuery, TIBTable: addition:
253     property MasterDetailDelay: integer {defaults to zero}
254    
255     When non-zero and the dataset is a detail table referencing a master table
256     through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
257     then a synchronisation delay is added (in milliseconds) between the master
258     row changing and the detail dataset being re-opened. If the master dataset
259     is scrolled before the delay expires then the delay is reset. This can be used
260     to avoid performance overheads when scrolling through a large master dataset.
261    
262     Note: uses fptimer and hence requires a thread manager. Under Linux the
263     chreads unit must be included in your project. TTimer is not used in order
264 tony 213 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
265 tony 209
266     17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
267     with Extract Option eoDatabase.
268    
269     18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
270 tony 225 When a deLayoutChanged event is reported on the ListSource dataset, the
271 tony 209 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
272     relationship with the control's datasource (master).
273    
274 tony 221 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
275    
276 tony 226 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
277 tony 221 stubs. Pedantic fix really, as procedures output in dependency order anyway.
278    
279 tony 226 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
280 tony 221 DDL (Firebird 3 and later only).
281    
282 tony 225 22. TIBLookupComboBox Autocomplete Fixes:
283     i. Only appended text is now selected after autocomplete.
284     ii. Uppercase keys no longer ignored for autocomplete.
285     iii. Retain Prefix case is now honoured correctly.
286     iv. When a DataSource is assigned, typing after autocomplete now extends prefix
287     before autocomplete performed. i.e. behaviour now the same as when
288     no DataSource assigned.
289    
290 tony 226 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
291 tony 225 between SQL statements.
292    
293     24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
294     ObjectNames are converted to upper case before matching against metadata object
295     names, unless the objectname is delimited by double quotes, in which case, the
296     double quotes are removed and the remaining string is used (unmodified) to match
297     against the metadata object name.
298    
299     If true then the ObjectName is used as is without modification and matched
300     against the metadata object name. No attempt is made to remove double quotes.
301    
302 tony 226 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
303     with eoTrigger, these extract types can be used to select only Database Triggers,
304     or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
305    
306 tony 227 26. TIBXScript: If an exception occurs during the processing of a statement, the
307     statement separate character is now reset to the default (';').
308    
309 tony 229 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
310    
311     28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
312     a commit or reconnect statement and instead activated only when next SQL statement
313     is executed.
314    
315     29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
316    
317     30. TIBXScript: case insensitive regex now used when matching statements instead of
318     converting statement to upper case.
319    
320     31. TIBExtract: metadata comments now supported. New published property
321     IncludeMetaDataComments (default true). If true then metadata comments included
322     in extracted DDL. New Extract Object member eoComments. This may be used with
323     ExtractObject method to list all metadata comments.
324    
325     32. TIBExtract: ListObjectNames method added.
326    
327 tony 231 33. Updated Database component editor to support additional connection string
328     types.
329    
330 tony 209 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
331    
332 tony 151 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
333 tony 152 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
334 tony 151 RELEASE.
335    
336     NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
337    
338 tony 107 1. IBExtract: Identity columns - add additional check for null column for generator name.
339 tony 101
340     2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
341     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
342 tony 107 information). However, this is also a very useful mechanism for returning updated computed by
343     column values. Values returned as a result of executing an Insert or Update statement
344     replace existing values in the current row for each corresponding column.
345 tony 101
346 tony 107 Previously, if a dataset's select query included read only (computed by) fields then
347     an automatic row refresh was performed after an insert or update query had been processed,
348     irrespective of the setting of the "ForcedUpdates" property. This has changed such
349     that an automatic refresh is no longer performed if an insert or update query contains
350     a returning clause that updates one or more fields on the current row. A full row
351     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
352     field values and the select query contains read only fields. Use of Insert/update
353 tony 123 returning should be significantly more efficient than executing a refresh query.
354 tony 107
355     This behaviour change is intended to be backwards compatible and there should be no need to change
356     existing programs, other than to improve performance by using the new capability.
357    
358 tony 118 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
359     they are called when the dataset row is being deleted, there is no value in
360     updating the current record from the query result. Instead, a new event handler
361     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
362     an OnDeleteReturning event handler is provided then it is called with the IResults returned
363     by the query. The event handler can then interrogate the query results and
364     perform whatever action is necessary. For example to confirm, to the user,
365     the deletion of a row with the returned values.
366    
367     4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
368 tony 107 any Computed By or Identity Columns. The IBTables example has been updated to
369     illustrate the computation of the employee Full Name on update.
370    
371 tony 118 5. TIBTable: The GeneratorField property is now published.
372 tony 107
373 tony 118 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
374 tony 101 When InsertSQL is generated, the Identity columns are not included in the list of values to
375     be inserted. A RETURNING clause is added to the insert statement to return the value of
376     each Identity column after the insert is executed.
377    
378 tony 118 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
379 tony 107 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
380     Insert..Returning clause.
381 tony 104
382 tony 118 8. TIBGenerator: small performance improvement by not preparing query each time
383 tony 107 a new value is generated.
384 tony 104
385 tony 118 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
386 tony 107
387 tony 118 10. Property editors will now sync table name to a System Table when "Include System
388     Tables" is selected and the query is for a System Table.
389 tony 105
390 tony 118 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
391 tony 107 values are no longer converted to milliseconds from TDateTime and then back again
392     to TDateTime (the conversion to milliseconds is the default TDataset approach).
393 tony 105
394 tony 118 12. Property Editors handling of Stored Procedures.
395 tony 107 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
396     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
397     query).
398     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
399 tony 106
400 tony 118 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
401 tony 107 can be used to select a package. If non-empty, the stored procedure name is
402     expected to be a stored procedure defined in the specified package and the
403     generated SQL will be as required for a stored procedure located in a package.
404    
405 tony 118 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
406 tony 107 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
407     which a stored procedure can be selected. With no package name selected, non-package
408     stored procedures are listed.
409    
410 tony 118 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
411 tony 109 for password on reconnect.
412 tony 107
413 tony 143 16. TIBDatabase: use IAttachment for connection default character set id, code page
414 tony 118 and character set name.
415 tony 109
416 tony 118 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
417     DB info lookups"
418    
419 tony 143 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
420 tony 118
421 tony 127 19. Add a property Editor for TIBUpdate.RefreshSQL.
422 tony 118
423 tony 139 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
424     parameters. This stops an exception being raised when the field cannot be
425     located in the record buffer.
426 tony 127
427 tony 141 21. Property Editors now automatically include System Tables when opened and when the query table
428     is a System Table.
429 tony 139
430 tony 150 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
431 tony 143 This avoids errors due to a stale SQRB or SRB being used for the next query.
432 tony 141
433 tony 143 23. IBServices: Service attach parameters now include "expected_db". This is used to
434     add the SPB item isc_spb_expected_db. This names a database using
435     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
436     database. examples/services re-written to illustrate use of "expected_db".
437 tony 141
438 tony 143 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
439     This avoids truncated backups when the server returns a timeout (busy) response.
440    
441     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
442    
443     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
444     databasenames. These are respectively expanded to the local system's temp directory
445 tony 150 (including trailing delimiter) or to a prescribed data directory (including
446 tony 143 trailing delimiter). Under Unix systems the data directory is a hidden directory
447     in the user's home directory. The hidden directory name is either the string returned
448     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
449     Under Windows, the directory is the same as the Data Directory as decribed
450     above but instead prefixed by the User's application data path. These may be
451 tony 150 used to improve application portability for Personal Databases.
452 tony 143
453     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
454     this has not worked for a long time and is not useful either. FieldDefs should be
455     managed using the Fields Editor as with any other dataset. To access the fields
456     editor for a TIBTable component, double click on the component. The fields editor
457     is then displayed.
458    
459     28. TIBDatabaseInfo: new properties/function
460     * DateDBCreated (returns date/time database created)
461     * TransactionCount (returns no. of active transactions)
462     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
463     * PagesFree (Firebird 3 or later)
464     * PagesUsed (Firebird 3 or later)
465     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
466     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
467    
468     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
469    
470     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
471    
472     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
473     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
474    
475     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
476     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
477     firing during backup and restore.
478    
479     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
480     for verbose output using the new property "StatisticsRequested".
481     see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
482    
483     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
484    
485     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
486     palette. This uses the online validation feature added in Firebird 2.5. The
487     services's properties enable inclusion/exclusion of tables and indexes using
488     regular expressions. See.
489     https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
490    
491     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
492     option on a database.
493    
494     37. TIBCustomService: Assign method implemented to allow copying of service login
495     context between service API components. "Detach" method now only detaches
496     service when last reference to the service interface detaches. Tidy up of
497     code for SetActive and Attach methods including password hiding.
498    
499 tony 150 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
500 tony 143 and used to determine the auth method and protocol used for the connection.
501    
502     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
503     a Create Database Statement generated by IBX.
504    
505     40. All IBServices now have an additional published property "PortNo". This may
506     be set to a non-standard port number when necessary. If zero then the default
507     port number is used.
508    
509     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
510     and not just the mouse.
511    
512     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
513    
514     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
515     image index and selected image index for each node to be set from a database field.
516    
517     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
518     then database schema includes grants to all users. If not present then the
519     only user grants included are those to User PUBLIC.
520    
521     45. TIBTreeView: performance improvement. When expanding include both expanded node
522     and child nodes in dataset.
523    
524    
525 tony 90 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
526 tony 56
527     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
528     changes.
529    
530 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
531     Bug could result in truncated multi-byte character set values.
532    
533 tony 60 3. Changes consequential on moving fbintf character set utility functions from
534     IFirebirdAPI to IAttachment.
535    
536 tony 62 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
537    
538 tony 64 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
539     results in autocomplete ignoring prefix text.
540    
541 tony 65 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
542     entering a new name into the text box.
543    
544 tony 66 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
545     Firebird rather than recomputing it.
546    
547 tony 67 8. Property Editor positioning tidy up: All IBX Property editors should now be
548     screen centre. Previously some were "poDesigned" which may be inappropriate
549     for multi monitor desktops.
550    
551 tony 80 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
552    
553     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
554     a transaction and always reset the object.
555    
556     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
557    
558     13. TIBXScript: Allow for override of database filename in Create Database statements.
559    
560     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
561     to a gbak format archive.
562    
563     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
564    
565     16. IBLocaldb: Drop database if error creating an empty database.
566    
567     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
568     unless selected node not in current dataset.
569    
570     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
571     to TIBCustomService, and IBlocalDB code tidy up.
572    
573     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
574     behaviour due to uninitialised variable.
575    
576     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
577     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
578    
579     21. IBSQL: When Database changed ensure that all resources are freed.
580    
581     22. IBCustomDataset: When database changed ensure that queries an unprepared.
582    
583 tony 84 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
584     * Line Wrap on SQL Token boundaries (on user command)
585     * auto-complete table names in drop down list of table names
586     * Double click on tablename or field name adds to SQL text
587 tony 80
588     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
589    
590     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
591     TVariantArray. Seems to avoid memory corruption in Windows (probably a
592     workaround for a problem in fpc 3.0.4 win64).
593    
594     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
595    
596 tony 83 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
597    
598 tony 51 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
599 tony 49
600 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
601 tony 49 include remote system name.
602    
603     2. TIBExtract: No longer include comment header and COMMIT statement for empty
604     tables when data included in output.
605    
606     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
607     and timing information to be written to stdout. This may be used to locate
608     performance bottlenecks.
609    
610     4. SQLParser: only call "OnChanging" event handler when value is different.
611    
612     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
613    
614 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
615     that BindFields is called when the query is next activated. Avoids FieldName
616     not found error.
617    
618 tony 80 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
619     purpose and allows the programmer to define any action they want for Update, Insert
620     or Delete. This may be complex SQL (similar to a Trigger), application specific
621     filtering of updates, or use of statements such as Grant or Revoke instead of
622     normal DML. See User Manual for more information.
623    
624 tony 47 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
625 tony 45
626 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
627 tony 45
628 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
629    
630     3. TIBExtract: data formatted as Charset set "octets" is now output using
631     hexadecimal notation.
632    
633     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
634     using a simple XML format.
635    
636     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
637     grants to these objects.
638    
639     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
640     dependency problems restoring complex databases.
641    
642     7. TIBXScript: This component has been restructured to allow for the processing of
643     embedded XML in INSERT statements and to support interactive sources in addition
644     to non-interactive data sources such as files.
645    
646     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
647    
648     9. TIBXScript: ISQL compatiable Set statements are now supported:
649     SET SQL DIALECT
650     SET TERM
651     SET AUTODDL
652     SET BAIL
653     SET ECHO
654     SET COUNT
655     SET STATS
656     SET NAMES <character set>
657    
658     10. IBVersion unit added to hold current IBX Version Number information.
659    
660     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
661     and domain definitions.
662    
663     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
664     fully supported.
665    
666     13. TIBExtract: when a database dump includes data, the generator values are now also set.
667    
668     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
669    
670     IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
671    
672 tony 50 See also doc/IBX4LazarusGuide.pdf for important information on
673 tony 45 upgrading to IBX2.
674    
675     1. Size property of TIBStringField is now the width in characters of the field
676     and not the byte length. This applies only to multi-byte character sets such
677     as UTF8. The original approach aligned with TStringField. However, the TStringField
678     code is not recognised as a bug and hence this change to align the behaviour.
679     The TStringField change is expected in fpc 3.2.0.
680    
681     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
682     true (default) then Size property value saved in the lfm is ignored. Size is
683     always set from the dynamic information read from the database. It is unclear
684     why anyone would want to override this and set Size to false.
685    
686     3. ibxscript: should now handle correctly a Case..End statement within a procedure
687     block.
688    
689     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
690     exist when an attempt is made to connect to it (run time only) then an attempt
691     is made to create the database.
692    
693     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
694     has been successfully created as a result of a call to CreateDatabase or when
695     creating a database after it was found not to exist.
696    
697     6. DBControlGrid: a race condition could result in the wrong row image being
698     written to the cache. This has been avoided by a trip round the message
699     loop before rendering the row image.
700    
701     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
702     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
703     known to risk corrupt rendering of row images when the control is first
704     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
705     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
706    
707     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
708     a TDateEdit control located on an editor panel.
709    
710     9. TIBExtract: brought up-to-date plus many bug fixes.
711    
712     10. DBControlGrid: Removed memory leak when updating rows.
713    
714     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
715    
716 tony 43 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
717    
718     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
719     when target codepage is CP_NONE. This is a workaround for
720     http://bugs.freepascal.org/view.php?id=30622.
721    
722     2. DBLog option removed from TIBStatisticalService - not supported by server
723     since Firebird 1.5.
724    
725     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
726     similar.
727    
728     4. IBCodePage: updated mapping between codepages and character id.
729    
730     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
731     Firebird. Character sets with a char width of two are not UTF16.
732    
733     6. Strings received from the database are now always transliterated into UTF8
734     regardless of the database character set or connection character set. This
735     is for compatibility with the LCL.
736    
737 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
738 tony 41
739     1. IBBlob: Defer reading of blob until read method called. This avoids having to
740     read in an entire blob just to get the size of the blob. General performance
741     improvement when opening datasets containing blobs.
742    
743     2. Clearing a Blob now sets the corresponding field's modified flag.
744    
745     3. IBLookupCombo: When not performing auto-complete, original query sort order
746     is now used.
747    
748     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
749     determined.
750    
751     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
752    
753     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
754     lazarus 1.6.0
755    
756     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
757     compilation error.
758    
759 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
760    
761     1. No character set specified for connection: when a text blob is retrieved, the
762     character set is determined by looking up the native character set using then
763     Firebird API. Otherwise a text mode blob is assumed to have the same character
764     set as the connection.
765    
766     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
767     for Login Dialog returing a change to the database path.
768    
769     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
770     to be changed from that given in the TIBDatabase/TIBServer component and for the
771     entered value to be saved on a project specific basis (design time only).
772    
773     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
774     column fieldname. If they are the same then it is acts as a look up for the KeyValue
775     Otherwise, it sets the column text to the selected ListField Value.
776    
777     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
778     column width.
779    
780     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
781     and a case insensitive search is requested.
782    
783     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
784     or column ListSource.
785    
786     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
787     unprepare) when closing and the text has not changed.
788    
789     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
790     Less likely to cause a cursor re-use error on Windows.
791    
792     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
793     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
794    
795     11. TIBTreeView: Guard against nil destination on record changed
796    
797     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
798     string type with the code page set to reflect the returned field encoding after
799     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
800     earlier versions.
801    
802     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
803     will now result in transliteration to the code page specified for the Firebird driver
804     if the assigned string has a different code page. FPC 3.0.0 onwards only.
805    
806     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
807     is ignored and the lc_ctype value, when the database is opened, is set to align with
808     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
809     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
810     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
811     the GETACP is used to determine the Windows code page.
812    
813     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
814     name used as the lc_ctype when the database was opened. Only valid while the
815     Database is connected.
816    
817     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
818     id that corresponds to the DefaultCharSetName.
819    
820 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
821    
822     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
823     path is given and database attach fails due to access permission issues on the
824     temp directory or security database, then the attach is retried with "localhost:"
825     prefixing the databasename. This should avoid problems when the database has to
826     be accessed by a local (e.g. classic) server and libfbembed is used.
827    
828     2. Windows: revised search order for Firebird DLL:
829     i. The Firebird Embedded Server in the application Directory.
830     ii. If the FIREBIRD environment variable is set then the directory this
831     points to is searched for the FB Client DLL and then then underlying
832     "bin" directory.
833     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
834     is used to locate the Firebird installation directory and the underlying
835     "bin" directory is searched for the FB Client DLL.
836     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
837     are searched for the FB Client DLL.
838     v. The PATH Environment variable is used to search for the FB Client DLL.
839     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
840    
841     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
842     See doc/readme.scriptengine and example applications.
843    
844     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
845     simplify the use of the embedded firebird server on both Linux and Windows platforms.
846     See dpc/readme.localdatabase and example applications.
847    
848     5. IBDynamicGrid: Reordering on column header click should now also work for
849     dynamic columns.
850    
851     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
852     between incrementing/decrementing the lock count and signalling the event.
853    
854 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
855    
856 tony 37 1.3.2 was never formally released and only made available as beta copies.
857    
858 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
859    
860     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
861    
862     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
863    
864     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
865     i.e. when it is a calculated field
866    
867     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
868     This problem was due to a race condition between recalculating row heights and
869     determining which row was selected by the mouse click. The row height calculation
870     is now deferred by an extra trip round the message loop allowing the row to
871     be always calculated on the current grid layout rather than risking it being
872     calculated on the grid layout after the expanded row has been shrunk.
873    
874     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
875     Windows.
876    
877     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
878     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
879 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
880 tony 35
881     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
882 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
883 tony 35
884     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
885     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
886 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
887 tony 35
888     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
889     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
890     implies no truncation.
891    
892     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
893    
894     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
895     (avoids "Not in Edit Mode" error).
896    
897     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
898    
899     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
900     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
901    
902     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
903    
904     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
905    
906     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
907    
908     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
909    
910 tony 33 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
911 tony 31
912     1. OnCloseUp Event Handler added to TDBLookupProperties
913    
914     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
915     problem with row size when exception is called.
916    
917     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
918    
919     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
920     in a TCustomComboBox and ignores return key if in a TCustomMemo
921    
922     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
923     keyed in i.e. when autocomplete not performed
924    
925 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
926     console mode applications with all LCL required functions (builtin dialogs and
927     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
928     not included in your project, IBX should compile and link with a console mode program.
929     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
930     console mode application or the IDE will automatically assume that your
931     application is GUI based. Instead, you should include the ibexpressconsolemode package.
932 tony 31
933     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
934     to use the built in dialogs and cursor management. IBDialogs is
935 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
936 tony 31 This should be the case for all projects created through the IDE. This is why
937     you do not want to add the ibexpress package to console mode applications. The
938     ibexpressconsolemode package has been created to allow console mode programs
939     to avoid adding LCL dependencies when using IBX, while still having the
940     unit search paths set up correctly.
941    
942 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
943     each project's source file (*.lpr).
944    
945 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
946     exists, you have to first open the package in the IDE and then close it. This
947     adds it to the most recently accessed packages list. To make it permanently
948     available, add the package name to lazarus' staticpackages.inc file.
949    
950 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
951 tony 31
952     7. SQL Parser can now accept quoted strings that include new lines
953    
954     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
955     of text on start of edit. This is particularly useful when tabbing to a
956     column and then inserting text.
957    
958     9. New Examples provided for IB Services and ISQLMonitor.
959    
960     10. Fix error when writing to blob streams that recorded only the last buffer
961     write in the blob stream. In most cases, this did not cause a problem as the
962     IB Blob Stream is written in a single write. However, with the TDBImage, write
963     of a graphic type prefix was lost which caused a problem when the image could
964     not be automatically recognised.
965    
966     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
967 tony 33 already open" errors due to random numbers used for the cursor name being identical.
968 tony 31
969     12. IBTable: corrected error that could result in an "Index out of bounds" error
970     when opening the table and the Primary Key is the last or only column in the
971     table. Thanks to Rick Hoover for the fix.
972    
973 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
974     of "UTF-8", and update list of available database character sets. Existing
975     users should check the current lc_ctype setting in their applications.
976 tony 29
977 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
978    
979 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
980     empty Params property.
981    
982     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
983     Link now set up in Loaded method - avoids occasional failure to apply
984     SQL markup on initial open.
985    
986     3. "Employees" example performance improvements when scrolling.
987    
988     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
989     TFrame. Force recaching of selected frame to avoid GTK race (results in a
990     random image cached).
991    
992     5. DBControlGrid: Should now react to changes in panel height at run time.
993    
994     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
995     even when further rows exist.
996    
997     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
998     always be derived from panel height and setting this property can cause confusion.
999     Note for existing projects: to avoid a missing property error at run time,
1000     each form using the DBControlGrid must be opened, updated and saved in the IDE
1001     in order to remove the property value from the lfm.
1002    
1003    
1004 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1005 tony 27
1006     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1007     call Prepare before setting parameter values.
1008    
1009     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1010    
1011     3. Code tidyup and more robust handling of dsql information result vector.
1012    
1013     4. Support for centralised handling of transaction status changes. TIBTransaction
1014     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1015     and "AfterExecQuery". The first three are called after the same event is called
1016     for an IBCustomDataSet descendent using the Transaction. The fourth is called
1017     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1018     enable monitoring of transaction status changes for a given transaction to be
1019     handled in a single place. For example, when a change to the dataset occurs
1020     an indicator can be set that shows the user that in order to save changes,
1021     the transaction should be committed. Rather than doing this per dataset, this
1022     can now be done per transaction.
1023    
1024     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1025     the dataset is scrolled. However, any changes to the current row are, by default,
1026     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1027     have a new property "DataSetCloseAction" that adds automatic posting of changes
1028     on dataset close. If this property is set to dcDiscardChanges (default) then the
1029     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1030     then IBX will attempt to post any unsaved changes before the dataset is closed
1031     (and after the BeforeClose event handler is called). The exception is when the
1032     dataset is being closed as a result of a transaction rollback. In this case,
1033     no action is taken and any unsaved changes are discarded. This avoids both
1034     unnecessary overhead and the risk that a validation error may occur in the Post
1035     raising an exception and thereby preventing a rollback.
1036    
1037     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1038     In earlier versions, the Display Width was set to the maximum byte width rather than the character
1039     width. Display Widths are now corrected by dividing by the max byte width per character.
1040     For UTF8 character sets, the byte width is four and hence the Display Width will be
1041     the byte width divided by 4. The byte width of each character set is determined
1042     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1043     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1044    
1045     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1046    
1047     8. IBLookupComboEditBox: List should now always be restored to full list when the
1048     control loses focus. Default Key press default interval reduced to 200ms.
1049    
1050     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1051     when dataset rows are less than visible rows.
1052    
1053     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1054     does not exist or DataSet is empty. More responsive on dataset open. New event
1055     OnRestorePosition. Column sort disabled if no header row.
1056    
1057     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1058     while dataset state is dsInsert. Avoids posting errors.
1059    
1060     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1061     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1062    
1063     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1064    
1065     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1066     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1067     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1068     always "posts" the current record regardless or whether or not it may be more appropriate
1069     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1070     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1071     as the first action of the "Post" method and allows the handler to convert the Post
1072     into a Cancel if that is the appropriate action on moving to a different row. This is
1073     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1074     raised here, but it may still be more appropriate to validate a post and signal
1075     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1076    
1077     15. On Unix derived systems, the Firebird library name can now be given as a colon
1078     separated list. Each library name on the list is tried in turn, in left to right
1079     order with the first found being used as the firebird library. By default, on Linux,
1080     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1081     overidden by the FBLIB environment variable or the OnGetLibraryName function.
1082    
1083     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1084     then it will still attempt to access the database via the Firebird Server and will
1085     require a username and password. If only the pathname is given, then the username
1086     and password should be omitted and the unix file permissions are used to grant
1087     access.
1088    
1089 tony 33 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1090 tony 23
1091     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1092     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1093     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1094 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
1095 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1096    
1097     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1098 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1099 tony 23 takes place during database access. This may be useful when there are performance issues with
1100     the change of cursor. Setting the property to false suppresses the change of cursor.
1101    
1102     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1103     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1104     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1105     making all changes permanent immediately rather than when the transaction is explicitly
1106     committed.
1107    
1108 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1109 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

1115 tony 33 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1116 tony 21
1117     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1118     This is typically used during an "OnBeforeOpen" event handler to manipulate the
1119     "Where" and "Having" clauses to implement user specified filters of arbitrary
1120     complexity.
1121    
1122     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1123     three new data aware controls dependent on IBX and which make use of the SQL Parser.
1124     These are:
1125    
1126     - TIBLookupComboEditBox
1127     - TIBDynamicGrid
1128     - TIBTreeview
1129    
1130     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1131     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1132     to revise the available list and restrict it to items that are prefixed by the
1133 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
1134 tony 21 newly typed entry to be added to the list dataset and included in the available
1135     list items.
1136    
1137     TIBDynamicGrid is a TDBGrid descendent that provides for:
1138     - automatic resizing of selected columns to fill the available row length
1139     - automatic positioning and sizing of a "totals" control, typically at the
1140     column footer, on a per column basis.
1141     - DataSet resorting on header row click, sorting the dataset by the selected column.
1142     A second click on the same header cell reversed the sort order.
1143     - Support for a "Panel Editor". That is on clicking the indicator column, the row
1144     is automatically expanded and a panel superimposed on it. The panel can have any
1145     number of child controls, typically data aware controls with the same datasource
1146     as the grid allowing for editing of additional fields and more complex editors.
1147     - Reselection of the same row following resorting.
1148     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1149     Its properties are specified on a per column basis and allows for one or more
1150     columns to have their values selected from a list provided by a dataset.
1151     Autocomplete and autoinsert are also available. The existing picklist editor
1152     is unaffected by the extension.
1153    
1154     TIBTreeView is a data aware TCustomTreeView.
1155    
1156     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1157     zero scale will no longer return an error. An Int64 will be returned instead.
1158    
1159     4. TIBTransaction now has events for Before and After Transaction End and a new function
1160     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1161    
1162     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1163     repeated multiple times.
1164    
1165     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1166     check used to get in the way of using Stored Procedures, and "Update or Insert"
1167     statements.
1168    
1169     7. Insert, Modify and Delete property Editors now support Query Generation from
1170     Stored Procedures.
1171    
1172     8. Three new examples illustrate the use of the new IB Controls
1173    
1174    
1175 tony 33 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1176 tony 19
1177     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1178     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1179     Gabor Boros for reporting this problem and for testing the improvements).
1180    
1181     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1182     See readme.field+param.names in the doc folder.
1183    
1184     3. IBX SQL Editors will now automatically add double quotes around column names when the database
1185     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1186    
1187     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1188    
1189     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1190     actions.
1191    
1192     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1193     thanks to Yuriy Kopnin for pointing this out).
1194    
1195     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1196    
1197     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1198     for both fields and parameter setting.
1199    
1200     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1201     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1202    
1203     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1204     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1205    
1206     11. TIBTable now has a property editor for "MasterFields"

1208     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1209     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1210    
1211     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1212     of settings is unrecognised. Selecting this radio button has no effect on the settings.

1221     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1222     it is null. This allows for alternative user defined setting of the generator
1223    
1224     Many thanks to Julio Jiménez for this fix
1225    
1226     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1227     and suggests that the user may have forgotten to install it.

1231     1. Conditional compilation used to limit registration of TIntegerField to
1232     Lazarus versions less than 1.1
1233    
1234     2. When a database connection is created, character set is now by default set
1235     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1236     1250 to 1254.

1246     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1247     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1248    
1249     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1250     package is changed to do this (which it should do).
1251

1253    
1254     1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1255    
1256     2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1257    
1258     3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1259    
1260     4. Property editors should now correctly resize.
1261    
1262     5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1263     (restored original functionality)
1264    
1265     6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1266     library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
