1 tony 271 IBX Change Log version (2.3-3 Build 11348) Fri, 28 Dec 2018 10:04:17 +0000
2 tony 266
3 tony 267 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
4     and is used to override the default settings in the client side "firebird.conf" This
5     includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
6     Each line of the string list should be a setting in the same format as "firebird.conf".
7     For example "WireCompression = true" in order to request wire compression on the client side.
8 tony 266
9 tony 267 Note: explicit settings in the client side "firebird.conf" appear to take precedence
10     over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
11     also require a compatible setting in the server side "firebird.conf". For example
12     "WireCompression = true" must also be set in the server's "firebird.conf" for wire
13     compression to be used.
14 tony 266
15 tony 267 Whether or not WireCompression or WireCrypt are in use can be checked using the information
16     returned with the Client/Server protocol version. See ibx/examples/dbadmin and
17     ibx/examples/dbinfo for examples of how to display this information.
18 tony 263
19 tony 267 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
20     is a "convenience" property. If set the "WireCompression=true" is added to the
21     ConfigOverrides. If unchecked then this setting is removed.
22    
23 tony 270 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
24     not "INT64".
25    
26     4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
27     These are:
28     property TimestampFormat: string;
29     property DateFormat: string;
30     property TimeFormat: string;
31    
32     Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
33     DATETIME and TIME. The format strings use the standard FPC date/time format
34     characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
35    
36     If any of the above properties are set to an empty string, then the locale default
37     is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
38     locale default is extended by appending '.zzz' to include milliseconds.
39    
40     TIBCSVDataOut by default sets these properties to the empty string, while the other
41     two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
42    
43     5. New published property for TIBCSVDataOut:
44     property QuoteStrings: boolean (default true)
45    
46     If false then strings are unquoted, otherwise, the QuoteChar property value is
47     used to delimit each and every string in the output.
48    
49     6. New published properties for TIBCSVDataOut:
50     property FieldSeparator: string;
51     property HeaderSeparator: string;
52    
53     Respectively, these provide the separator character(s) used to separate fields
54     in data and header rows. Both default to ','.
55    
56     7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
57     TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
58     property OnFormatTextString;
59    
60     This event handler can be used to process text strings before they are included
61     in the output e.g. to replace unprintable characters with alternative strings.
62     This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
63    
64     8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
65    
66     9. TIBQuery now uses IBX SQL Parser instead of TParams SQL parser in order to ensure
67     consistency with SQL queries.
68    
69     10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
70     When true, SQL statement parameter names are parsed case sensitive. Note for
71     TIBDataSet only applies to Select query.
72    
73 tony 271 11. IBEvents: removing a TIBEvent component from a form should no longer result in
74     an IDE exception.
75    
76 tony 267 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
77    
78 tony 263 1. Remove need to check for IsMultiThread by providing access to GUI timers via
79     IBGUIInterface. Note: master/detail delay timer does not apply to console
80     mode apps.
81    
82     2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
83     statement. This avoids problems if "Execute Block" is used as the Query.
84    
85     3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
86     internal SQL tokeniser routines.
87    
88     4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
89     as a select statement, with or without CTEs.
90    
91     5. IBSQLParser: parser now recognises the "ROWS" clause.
92    
93     6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
94     internal SQL tokeniser routines.
95    
96     7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
97     being raised for valid set statements processed by a data formatter.
98    
99     8. New published property for TIBDatabase and TIBXServicesConnection. This is
100     FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
101     the path of the Firebird Library used by the database/services connection.
102    
103     9. New read only public property for TIBDatabase and TIBXServicesConnection. This
104     is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
105     services connection.
106    
107     10.SQL Property editors now quote parameter names if "Quote identifier" is selected
108     or param name is not a valid SQL identifier.
109    
110     11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
111     view of whether the text box should be editable when no DataSource is specified.
112     TIBLookupComboEditBox has been updated to workaround this problem. As long as
113     ReadOnly is false, the text box is editable when no DataSource is specified.
114    
115     12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
116     the FBLIB environment variable. If you do not want to permit this then you
117     must modify the Register procedure in the design/IBDBReg.pas unit to remove
118     this setting.
119    
120 tony 241 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
121    
122     1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
123     Utf8EscapeControlChars
124    
125 tony 232 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
126 tony 101
127 tony 209 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
128     all previous copies of the IBX source code tree before installing this release.
129    
130     The IBX packages used by most users have not changed, with one exception. The
131     IBServices unit has been moved to the package iblegacyServices.lpk. To continue
132     to use the IBServices unit in your applications, please add the iblegacyServices
133     to the list of dependencies. To do this, open the Project Inspector and select
134     Add->New Requirement and select "ibLegacyServices" from the list of available
135     packages.
136    
137     1. New unit IBXServices. The IBXServices unit is a re-architectured update of
138     the IBServices unit providing what is intended to be a clearer and easier to
139     use set of IB Services components. See Chapter 10 of the IBX User Guide for
140     more information and the guide to "Firebird Service Management Using IBX".
141     As indicated above, the legacy services components are still available and
142     provided in a separate package. There is no need to update working applications
143     using the older versions except for an additional package dependency.
144    
145     2. The IBX packages and source code tree have been re-organised in an attempt to
146     finally get rid of the "duplicate ppu" warnings. This re-organisation should
147     not affect existing users. Section 2.3 of the IBX User Guide describes the
148     new set of IBX packages.
149    
150     3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
151     updated to use the new Services API components.
152    
153     4. The iblocal package has been updated to use the new Services API components.
154    
155     5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
156     TIBXSecurityService. It had been wrongly classified in the previous version
157     as a per database configuration item. It is global to a server and hence
158     correctly positioned as part of the Security Package. In the DBAdmin example,
159     the setting has moved to the mappings page.
160    
161     6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
162     are ignored.
163    
164     7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
165     closed before the database is dropped. Before and After Disconnect event handlers
166     are also fired.
167    
168     8. TIBTransaction: OnStartTransaction event now fires every time the transaction
169     is started and not just the first time.
170    
171     9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
172     depenendency with comp type.
173    
174     10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
175    
176     11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
177     then this is recognised and not ignored.
178    
179     12. TIBDataSet, TIBQuery, TIBTable: additions:
180     function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
181     function GetPerfStatistics(var stats: TPerfCounters): boolean;
182     property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
183    
184     GetRowsAffected returns the affected row counts from the last insert/update/delete
185     if EnableStatistics = true then GetPerfStatistics returns the current stats
186     counters for the select query. Note: stats accumulate after each fetch from
187     the database. To get total query cost after open, call the "Last" method
188     and then GetPerfStatistics.
189    
190     See ibx/examples/consolemode for an example of the use of GetPerfStatistics
191    
192     13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
193     in parenthesises.
194    
195     14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
196     SQL identifiers are always delimited by double quotes. If false, then they are
197     only delimited if the identifier is a reserved word, contains lower case or special
198     characters. Set this property to true to retain previous behaviour.
199    
200     15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
201     are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
202    
203     16. TIBDataSet, TIBQuery, TIBTable: addition:
204     property MasterDetailDelay: integer {defaults to zero}
205    
206     When non-zero and the dataset is a detail table referencing a master table
207     through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
208     then a synchronisation delay is added (in milliseconds) between the master
209     row changing and the detail dataset being re-opened. If the master dataset
210     is scrolled before the delay expires then the delay is reset. This can be used
211     to avoid performance overheads when scrolling through a large master dataset.
212    
213     Note: uses fptimer and hence requires a thread manager. Under Linux the
214     chreads unit must be included in your project. TTimer is not used in order
215 tony 213 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
216 tony 209
217     17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
218     with Extract Option eoDatabase.
219    
220     18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
221 tony 225 When a deLayoutChanged event is reported on the ListSource dataset, the
222 tony 209 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
223     relationship with the control's datasource (master).
224    
225 tony 221 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
226    
227 tony 226 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
228 tony 221 stubs. Pedantic fix really, as procedures output in dependency order anyway.
229    
230 tony 226 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
231 tony 221 DDL (Firebird 3 and later only).
232    
233 tony 225 22. TIBLookupComboBox Autocomplete Fixes:
234     i. Only appended text is now selected after autocomplete.
235     ii. Uppercase keys no longer ignored for autocomplete.
236     iii. Retain Prefix case is now honoured correctly.
237     iv. When a DataSource is assigned, typing after autocomplete now extends prefix
238     before autocomplete performed. i.e. behaviour now the same as when
239     no DataSource assigned.
240    
241 tony 226 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
242 tony 225 between SQL statements.
243    
244     24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
245     ObjectNames are converted to upper case before matching against metadata object
246     names, unless the objectname is delimited by double quotes, in which case, the
247     double quotes are removed and the remaining string is used (unmodified) to match
248     against the metadata object name.
249    
250     If true then the ObjectName is used as is without modification and matched
251     against the metadata object name. No attempt is made to remove double quotes.
252    
253 tony 226 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
254     with eoTrigger, these extract types can be used to select only Database Triggers,
255     or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
256    
257 tony 227 26. TIBXScript: If an exception occurs during the processing of a statement, the
258     statement separate character is now reset to the default (';').
259    
260 tony 229 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
261    
262     28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
263     a commit or reconnect statement and instead activated only when next SQL statement
264     is executed.
265    
266     29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
267    
268     30. TIBXScript: case insensitive regex now used when matching statements instead of
269     converting statement to upper case.
270    
271     31. TIBExtract: metadata comments now supported. New published property
272     IncludeMetaDataComments (default true). If true then metadata comments included
273     in extracted DDL. New Extract Object member eoComments. This may be used with
274     ExtractObject method to list all metadata comments.
275    
276     32. TIBExtract: ListObjectNames method added.
277    
278 tony 231 33. Updated Database component editor to support additional connection string
279     types.
280    
281 tony 209 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
282    
283 tony 151 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
284 tony 152 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
285 tony 151 RELEASE.
286    
287     NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
288    
289 tony 107 1. IBExtract: Identity columns - add additional check for null column for generator name.
290 tony 101
291     2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
292     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
293 tony 107 information). However, this is also a very useful mechanism for returning updated computed by
294     column values. Values returned as a result of executing an Insert or Update statement
295     replace existing values in the current row for each corresponding column.
296 tony 101
297 tony 107 Previously, if a dataset's select query included read only (computed by) fields then
298     an automatic row refresh was performed after an insert or update query had been processed,
299     irrespective of the setting of the "ForcedUpdates" property. This has changed such
300     that an automatic refresh is no longer performed if an insert or update query contains
301     a returning clause that updates one or more fields on the current row. A full row
302     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
303     field values and the select query contains read only fields. Use of Insert/update
304 tony 123 returning should be significantly more efficient than executing a refresh query.
305 tony 107
306     This behaviour change is intended to be backwards compatible and there should be no need to change
307     existing programs, other than to improve performance by using the new capability.
308    
309 tony 118 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
310     they are called when the dataset row is being deleted, there is no value in
311     updating the current record from the query result. Instead, a new event handler
312     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
313     an OnDeleteReturning event handler is provided then it is called with the IResults returned
314     by the query. The event handler can then interrogate the query results and
315     perform whatever action is necessary. For example to confirm, to the user,
316     the deletion of a row with the returned values.
317    
318     4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
319 tony 107 any Computed By or Identity Columns. The IBTables example has been updated to
320     illustrate the computation of the employee Full Name on update.
321    
322 tony 118 5. TIBTable: The GeneratorField property is now published.
323 tony 107
324 tony 118 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
325 tony 101 When InsertSQL is generated, the Identity columns are not included in the list of values to
326     be inserted. A RETURNING clause is added to the insert statement to return the value of
327     each Identity column after the insert is executed.
328    
329 tony 118 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
330 tony 107 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
331     Insert..Returning clause.
332 tony 104
333 tony 118 8. TIBGenerator: small performance improvement by not preparing query each time
334 tony 107 a new value is generated.
335 tony 104
336 tony 118 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
337 tony 107
338 tony 118 10. Property editors will now sync table name to a System Table when "Include System
339     Tables" is selected and the query is for a System Table.
340 tony 105
341 tony 118 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
342 tony 107 values are no longer converted to milliseconds from TDateTime and then back again
343     to TDateTime (the conversion to milliseconds is the default TDataset approach).
344 tony 105
345 tony 118 12. Property Editors handling of Stored Procedures.
346 tony 107 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
347     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
348     query).
349     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
350 tony 106
351 tony 118 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
352 tony 107 can be used to select a package. If non-empty, the stored procedure name is
353     expected to be a stored procedure defined in the specified package and the
354     generated SQL will be as required for a stored procedure located in a package.
355    
356 tony 118 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
357 tony 107 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
358     which a stored procedure can be selected. With no package name selected, non-package
359     stored procedures are listed.
360    
361 tony 118 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
362 tony 109 for password on reconnect.
363 tony 107
364 tony 143 16. TIBDatabase: use IAttachment for connection default character set id, code page
365 tony 118 and character set name.
366 tony 109
367 tony 118 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
368     DB info lookups"
369    
370 tony 143 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
371 tony 118
372 tony 127 19. Add a property Editor for TIBUpdate.RefreshSQL.
373 tony 118
374 tony 139 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
375     parameters. This stops an exception being raised when the field cannot be
376     located in the record buffer.
377 tony 127
378 tony 141 21. Property Editors now automatically include System Tables when opened and when the query table
379     is a System Table.
380 tony 139
381 tony 150 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
382 tony 143 This avoids errors due to a stale SQRB or SRB being used for the next query.
383 tony 141
384 tony 143 23. IBServices: Service attach parameters now include "expected_db". This is used to
385     add the SPB item isc_spb_expected_db. This names a database using
386     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
387     database. examples/services re-written to illustrate use of "expected_db".
388 tony 141
389 tony 143 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
390     This avoids truncated backups when the server returns a timeout (busy) response.
391    
392     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
393    
394     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
395     databasenames. These are respectively expanded to the local system's temp directory
396 tony 150 (including trailing delimiter) or to a prescribed data directory (including
397 tony 143 trailing delimiter). Under Unix systems the data directory is a hidden directory
398     in the user's home directory. The hidden directory name is either the string returned
399     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
400     Under Windows, the directory is the same as the Data Directory as decribed
401     above but instead prefixed by the User's application data path. These may be
402 tony 150 used to improve application portability for Personal Databases.
403 tony 143
404     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
405     this has not worked for a long time and is not useful either. FieldDefs should be
406     managed using the Fields Editor as with any other dataset. To access the fields
407     editor for a TIBTable component, double click on the component. The fields editor
408     is then displayed.
409    
410     28. TIBDatabaseInfo: new properties/function
411     * DateDBCreated (returns date/time database created)
412     * TransactionCount (returns no. of active transactions)
413     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
414     * PagesFree (Firebird 3 or later)
415     * PagesUsed (Firebird 3 or later)
416     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
417     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
418    
419     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
420    
421     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
422    
423     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
424     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
425    
426     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
427     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
428     firing during backup and restore.
429    
430     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
431     for verbose output using the new property "StatisticsRequested".
432     see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
433    
434     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
435    
436     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
437     palette. This uses the online validation feature added in Firebird 2.5. The
438     services's properties enable inclusion/exclusion of tables and indexes using
439     regular expressions. See.
440     https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
441    
442     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
443     option on a database.
444    
445     37. TIBCustomService: Assign method implemented to allow copying of service login
446     context between service API components. "Detach" method now only detaches
447     service when last reference to the service interface detaches. Tidy up of
448     code for SetActive and Attach methods including password hiding.
449    
450 tony 150 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
451 tony 143 and used to determine the auth method and protocol used for the connection.
452    
453     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
454     a Create Database Statement generated by IBX.
455    
456     40. All IBServices now have an additional published property "PortNo". This may
457     be set to a non-standard port number when necessary. If zero then the default
458     port number is used.
459    
460     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
461     and not just the mouse.
462    
463     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
464    
465     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
466     image index and selected image index for each node to be set from a database field.
467    
468     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
469     then database schema includes grants to all users. If not present then the
470     only user grants included are those to User PUBLIC.
471    
472     45. TIBTreeView: performance improvement. When expanding include both expanded node
473     and child nodes in dataset.
474    
475    
476 tony 90 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
477 tony 56
478     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
479     changes.
480    
481 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
482     Bug could result in truncated multi-byte character set values.
483    
484 tony 60 3. Changes consequential on moving fbintf character set utility functions from
485     IFirebirdAPI to IAttachment.
486    
487 tony 62 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
488    
489 tony 64 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
490     results in autocomplete ignoring prefix text.
491    
492 tony 65 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
493     entering a new name into the text box.
494    
495 tony 66 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
496     Firebird rather than recomputing it.
497    
498 tony 67 8. Property Editor positioning tidy up: All IBX Property editors should now be
499     screen centre. Previously some were "poDesigned" which may be inappropriate
500     for multi monitor desktops.
501    
502 tony 80 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
503    
504     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
505     a transaction and always reset the object.
506    
507     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
508    
509     13. TIBXScript: Allow for override of database filename in Create Database statements.
510    
511     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
512     to a gbak format archive.
513    
514     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
515    
516     16. IBLocaldb: Drop database if error creating an empty database.
517    
518     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
519     unless selected node not in current dataset.
520    
521     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
522     to TIBCustomService, and IBlocalDB code tidy up.
523    
524     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
525     behaviour due to uninitialised variable.
526    
527     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
528     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
529    
530     21. IBSQL: When Database changed ensure that all resources are freed.
531    
532     22. IBCustomDataset: When database changed ensure that queries an unprepared.
533    
534 tony 84 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
535     * Line Wrap on SQL Token boundaries (on user command)
536     * auto-complete table names in drop down list of table names
537     * Double click on tablename or field name adds to SQL text
538 tony 80
539     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
540    
541     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
542     TVariantArray. Seems to avoid memory corruption in Windows (probably a
543     workaround for a problem in fpc 3.0.4 win64).
544    
545     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
546    
547 tony 83 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
548    
549 tony 51 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
550 tony 49
551 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
552 tony 49 include remote system name.
553    
554     2. TIBExtract: No longer include comment header and COMMIT statement for empty
555     tables when data included in output.
556    
557     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
558     and timing information to be written to stdout. This may be used to locate
559     performance bottlenecks.
560    
561     4. SQLParser: only call "OnChanging" event handler when value is different.
562    
563     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
564    
565 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
566     that BindFields is called when the query is next activated. Avoids FieldName
567     not found error.
568    
569 tony 80 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
570     purpose and allows the programmer to define any action they want for Update, Insert
571     or Delete. This may be complex SQL (similar to a Trigger), application specific
572     filtering of updates, or use of statements such as Grant or Revoke instead of
573     normal DML. See User Manual for more information.
574    
575 tony 47 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
576 tony 45
577 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
578 tony 45
579 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
580    
581     3. TIBExtract: data formatted as Charset set "octets" is now output using
582     hexadecimal notation.
583    
584     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
585     using a simple XML format.
586    
587     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
588     grants to these objects.
589    
590     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
591     dependency problems restoring complex databases.
592    
593     7. TIBXScript: This component has been restructured to allow for the processing of
594     embedded XML in INSERT statements and to support interactive sources in addition
595     to non-interactive data sources such as files.
596    
597     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
598    
599     9. TIBXScript: ISQL compatiable Set statements are now supported:
600     SET SQL DIALECT
601     SET TERM
602     SET AUTODDL
603     SET BAIL
604     SET ECHO
605     SET COUNT
606     SET STATS
607     SET NAMES <character set>
608    
609     10. IBVersion unit added to hold current IBX Version Number information.
610    
611     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
612     and domain definitions.
613    
614     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
615     fully supported.
616    
617     13. TIBExtract: when a database dump includes data, the generator values are now also set.
618    
619     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
620    
621     IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
622    
623 tony 50 See also doc/IBX4LazarusGuide.pdf for important information on
624 tony 45 upgrading to IBX2.
625    
626     1. Size property of TIBStringField is now the width in characters of the field
627     and not the byte length. This applies only to multi-byte character sets such
628     as UTF8. The original approach aligned with TStringField. However, the TStringField
629     code is not recognised as a bug and hence this change to align the behaviour.
630     The TStringField change is expected in fpc 3.2.0.
631    
632     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
633     true (default) then Size property value saved in the lfm is ignored. Size is
634     always set from the dynamic information read from the database. It is unclear
635     why anyone would want to override this and set Size to false.
636    
637     3. ibxscript: should now handle correctly a Case..End statement within a procedure
638     block.
639    
640     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
641     exist when an attempt is made to connect to it (run time only) then an attempt
642     is made to create the database.
643    
644     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
645     has been successfully created as a result of a call to CreateDatabase or when
646     creating a database after it was found not to exist.
647    
648     6. DBControlGrid: a race condition could result in the wrong row image being
649     written to the cache. This has been avoided by a trip round the message
650     loop before rendering the row image.
651    
652     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
653     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
654     known to risk corrupt rendering of row images when the control is first
655     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
656     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
657    
658     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
659     a TDateEdit control located on an editor panel.
660    
661     9. TIBExtract: brought up-to-date plus many bug fixes.
662    
663     10. DBControlGrid: Removed memory leak when updating rows.
664    
665     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
666    
667 tony 43 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
668    
669     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
670     when target codepage is CP_NONE. This is a workaround for
671     http://bugs.freepascal.org/view.php?id=30622.
672    
673     2. DBLog option removed from TIBStatisticalService - not supported by server
674     since Firebird 1.5.
675    
676     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
677     similar.
678    
679     4. IBCodePage: updated mapping between codepages and character id.
680    
681     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
682     Firebird. Character sets with a char width of two are not UTF16.
683    
684     6. Strings received from the database are now always transliterated into UTF8
685     regardless of the database character set or connection character set. This
686     is for compatibility with the LCL.
687    
688 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
689 tony 41
690     1. IBBlob: Defer reading of blob until read method called. This avoids having to
691     read in an entire blob just to get the size of the blob. General performance
692     improvement when opening datasets containing blobs.
693    
694     2. Clearing a Blob now sets the corresponding field's modified flag.
695    
696     3. IBLookupCombo: When not performing auto-complete, original query sort order
697     is now used.
698    
699     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
700     determined.
701    
702     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
703    
704     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
705     lazarus 1.6.0
706    
707     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
708     compilation error.
709    
710 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
711    
712     1. No character set specified for connection: when a text blob is retrieved, the
713     character set is determined by looking up the native character set using then
714     Firebird API. Otherwise a text mode blob is assumed to have the same character
715     set as the connection.
716    
717     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
718     for Login Dialog returing a change to the database path.
719    
720     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
721     to be changed from that given in the TIBDatabase/TIBServer component and for the
722     entered value to be saved on a project specific basis (design time only).
723    
724     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
725     column fieldname. If they are the same then it is acts as a look up for the KeyValue
726     Otherwise, it sets the column text to the selected ListField Value.
727    
728     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
729     column width.
730    
731     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
732     and a case insensitive search is requested.
733    
734     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
735     or column ListSource.
736    
737     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
738     unprepare) when closing and the text has not changed.
739    
740     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
741     Less likely to cause a cursor re-use error on Windows.
742    
743     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
744     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
745    
746     11. TIBTreeView: Guard against nil destination on record changed
747    
748     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
749     string type with the code page set to reflect the returned field encoding after
750     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
751     earlier versions.
752    
753     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
754     will now result in transliteration to the code page specified for the Firebird driver
755     if the assigned string has a different code page. FPC 3.0.0 onwards only.
756    
757     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
758     is ignored and the lc_ctype value, when the database is opened, is set to align with
759     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
760     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
761     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
762     the GETACP is used to determine the Windows code page.
763    
764     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
765     name used as the lc_ctype when the database was opened. Only valid while the
766     Database is connected.
767    
768     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
769     id that corresponds to the DefaultCharSetName.
770    
771 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
772    
773     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
774     path is given and database attach fails due to access permission issues on the
775     temp directory or security database, then the attach is retried with "localhost:"
776     prefixing the databasename. This should avoid problems when the database has to
777     be accessed by a local (e.g. classic) server and libfbembed is used.
778    
779     2. Windows: revised search order for Firebird DLL:
780     i. The Firebird Embedded Server in the application Directory.
781     ii. If the FIREBIRD environment variable is set then the directory this
782     points to is searched for the FB Client DLL and then then underlying
783     "bin" directory.
784     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
785     is used to locate the Firebird installation directory and the underlying
786     "bin" directory is searched for the FB Client DLL.
787     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
788     are searched for the FB Client DLL.
789     v. The PATH Environment variable is used to search for the FB Client DLL.
790     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
791    
792     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
793     See doc/readme.scriptengine and example applications.
794    
795     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
796     simplify the use of the embedded firebird server on both Linux and Windows platforms.
797     See dpc/readme.localdatabase and example applications.
798    
799     5. IBDynamicGrid: Reordering on column header click should now also work for
800     dynamic columns.
801    
802     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
803     between incrementing/decrementing the lock count and signalling the event.
804    
805 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
806    
807 tony 37 1.3.2 was never formally released and only made available as beta copies.
808    
809 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
810    
811     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
812    
813     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
814    
815     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
816     i.e. when it is a calculated field
817    
818     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
819     This problem was due to a race condition between recalculating row heights and
820     determining which row was selected by the mouse click. The row height calculation
821     is now deferred by an extra trip round the message loop allowing the row to
822     be always calculated on the current grid layout rather than risking it being
823     calculated on the grid layout after the expanded row has been shrunk.
824    
825     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
826     Windows.
827    
828     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
829     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
830 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
831 tony 35
832     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
833 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
834 tony 35
835     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
836     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
837 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
838 tony 35
839     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
840     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
841     implies no truncation.
842    
843     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
844    
845     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
846     (avoids "Not in Edit Mode" error).
847    
848     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
849    
850     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
851     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
852    
853     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
854    
855     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
856    
857     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
858    
859     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
860

862 tony 31
863     1. OnCloseUp Event Handler added to TDBLookupProperties
864    
865     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
866     problem with row size when exception is called.
867    
868     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
869    
870     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
871     in a TCustomComboBox and ignores return key if in a TCustomMemo
872    
873     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
874     keyed in i.e. when autocomplete not performed
875    
876 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
877     console mode applications with all LCL required functions (builtin dialogs and
878     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
879     not included in your project, IBX should compile and link with a console mode program.
880     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
881     console mode application or the IDE will automatically assume that your
882     application is GUI based. Instead, you should include the ibexpressconsolemode package.
883 tony 31
884     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
885     to use the built in dialogs and cursor management. IBDialogs is
886 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
887 tony 31 This should be the case for all projects created through the IDE. This is why
888     you do not want to add the ibexpress package to console mode applications. The
889     ibexpressconsolemode package has been created to allow console mode programs
890     to avoid adding LCL dependencies when using IBX, while still having the
891     unit search paths set up correctly.
892    
893 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
894     each project's source file (*.lpr).
895    
896 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
897     exists, you have to first open the package in the IDE and then close it. This
898     adds it to the most recently accessed packages list. To make it permanently
899     available, add the package name to lazarus' staticpackages.inc file.
900    
901 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
902 tony 31
903     7. SQL Parser can now accept quoted strings that include new lines
904    
905     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
906     of text on start of edit. This is particularly useful when tabbing to a
907     column and then inserting text.
908    
909     9. New Examples provided for IB Services and ISQLMonitor.
910    
911     10. Fix error when writing to blob streams that recorded only the last buffer
912     write in the blob stream. In most cases, this did not cause a problem as the
913     IB Blob Stream is written in a single write. However, with the TDBImage, write
914     of a graphic type prefix was lost which caused a problem when the image could
915     not be automatically recognised.
916    
917     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
918 tony 33 already open" errors due to random numbers used for the cursor name being identical.
919 tony 31
920     12. IBTable: corrected error that could result in an "Index out of bounds" error
921     when opening the table and the Primary Key is the last or only column in the
922     table. Thanks to Rick Hoover for the fix.
923    
924 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
925     of "UTF-8", and update list of available database character sets. Existing
926     users should check the current lc_ctype setting in their applications.
927 tony 29
928 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
929    
930 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
931     empty Params property.
932    
933     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
934     Link now set up in Loaded method - avoids occasional failure to apply
935     SQL markup on initial open.
936    
937     3. "Employees" example performance improvements when scrolling.
938    
939     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
940     TFrame. Force recaching of selected frame to avoid GTK race (results in a
941     random image cached).
942    
943     5. DBControlGrid: Should now react to changes in panel height at run time.
944    
945     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
946     even when further rows exist.
947    
948     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
949     always be derived from panel height and setting this property can cause confusion.
950     Note for existing projects: to avoid a missing property error at run time,
951     each form using the DBControlGrid must be opened, updated and saved in the IDE
952     in order to remove the property value from the lfm.
953    
954    
955 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
956 tony 27
957     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
958     call Prepare before setting parameter values.
959    
960     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
961    
962     3. Code tidyup and more robust handling of dsql information result vector.
963    
964     4. Support for centralised handling of transaction status changes. TIBTransaction
965     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
966     and "AfterExecQuery". The first three are called after the same event is called
967     for an IBCustomDataSet descendent using the Transaction. The fourth is called
968     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
969     enable monitoring of transaction status changes for a given transaction to be
970     handled in a single place. For example, when a change to the dataset occurs
971     an indicator can be set that shows the user that in order to save changes,
972     the transaction should be committed. Rather than doing this per dataset, this
973     can now be done per transaction.
974    
975     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
976     the dataset is scrolled. However, any changes to the current row are, by default,
977     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
978     have a new property "DataSetCloseAction" that adds automatic posting of changes
979     on dataset close. If this property is set to dcDiscardChanges (default) then the
980     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
981     then IBX will attempt to post any unsaved changes before the dataset is closed
982     (and after the BeforeClose event handler is called). The exception is when the
983     dataset is being closed as a result of a transaction rollback. In this case,
984     no action is taken and any unsaved changes are discarded. This avoids both
985     unnecessary overhead and the risk that a validation error may occur in the Post
986     raising an exception and thereby preventing a rollback.
987    
988     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
989     In earlier versions, the Display Width was set to the maximum byte width rather than the character
990     width. Display Widths are now corrected by dividing by the max byte width per character.
991     For UTF8 character sets, the byte width is four and hence the Display Width will be
992     the byte width divided by 4. The byte width of each character set is determined
993     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
994     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
995    
996     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
997    
998     8. IBLookupComboEditBox: List should now always be restored to full list when the
999     control loses focus. Default Key press default interval reduced to 200ms.
1000    
1001     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1002     when dataset rows are less than visible rows.
1003    
1004     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1005     does not exist or DataSet is empty. More responsive on dataset open. New event
1006     OnRestorePosition. Column sort disabled if no header row.
1007    
1008     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1009     while dataset state is dsInsert. Avoids posting errors.
1010    
1011     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1012     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1013    
1014     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1015    
1016     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1017     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1018     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1019     always "posts" the current record regardless or whether or not it may be more appropriate
1020     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1021     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1022     as the first action of the "Post" method and allows the handler to convert the Post
1023     into a Cancel if that is the appropriate action on moving to a different row. This is
1024     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1025     raised here, but it may still be more appropriate to validate a post and signal
1026     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1027    
1028     15. On Unix derived systems, the Firebird library name can now be given as a colon
1029     separated list. Each library name on the list is tried in turn, in left to right
1030     order with the first found being used as the firebird library. By default, on Linux,
1031     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1032     overidden by the FBLIB environment variable or the OnGetLibraryName function.
1033    
1034     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1035     then it will still attempt to access the database via the Firebird Server and will
1036     require a username and password. If only the pathname is given, then the username
1037     and password should be omitted and the unix file permissions are used to grant
1038     access.
1039    
1040 tony 33 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1041 tony 23
1042     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1043     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1044     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1045 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
1046 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1047    
1048     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1049 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1050 tony 23 takes place during database access. This may be useful when there are performance issues with
1051     the change of cursor. Setting the property to false suppresses the change of cursor.
1052    
1053     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1054     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1055     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1056     making all changes permanent immediately rather than when the transaction is explicitly
1057     committed.
1058    
1059 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1060 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

1067 tony 21
1068     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1069     This is typically used during an "OnBeforeOpen" event handler to manipulate the
1070     "Where" and "Having" clauses to implement user specified filters of arbitrary
1071     complexity.
1072    
1073     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1074     three new data aware controls dependent on IBX and which make use of the SQL Parser.
1075     These are:
1076    
1077     - TIBLookupComboEditBox
1078     - TIBDynamicGrid
1079     - TIBTreeview
1080    
1081     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1082     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1083     to revise the available list and restrict it to items that are prefixed by the
1084 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
1085 tony 21 newly typed entry to be added to the list dataset and included in the available
1086     list items.
1087    
1088     TIBDynamicGrid is a TDBGrid descendent that provides for:
1089     - automatic resizing of selected columns to fill the available row length
1090     - automatic positioning and sizing of a "totals" control, typically at the
1091     column footer, on a per column basis.
1092     - DataSet resorting on header row click, sorting the dataset by the selected column.
1093     A second click on the same header cell reversed the sort order.
1094     - Support for a "Panel Editor". That is on clicking the indicator column, the row
1095     is automatically expanded and a panel superimposed on it. The panel can have any
1096     number of child controls, typically data aware controls with the same datasource
1097     as the grid allowing for editing of additional fields and more complex editors.
1098     - Reselection of the same row following resorting.
1099     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1100     Its properties are specified on a per column basis and allows for one or more
1101     columns to have their values selected from a list provided by a dataset.
1102     Autocomplete and autoinsert are also available. The existing picklist editor
1103     is unaffected by the extension.
1104    
1105     TIBTreeView is a data aware TCustomTreeView.
1106    
1107     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1108     zero scale will no longer return an error. An Int64 will be returned instead.
1109    
1110     4. TIBTransaction now has events for Before and After Transaction End and a new function
1111     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1112    
1113     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1114     repeated multiple times.
1115    
1116     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1117     check used to get in the way of using Stored Procedures, and "Update or Insert"
1118     statements.
1119    
1120     7. Insert, Modify and Delete property Editors now support Query Generation from
1121     Stored Procedures.
1122    
1123     8. Three new examples illustrate the use of the new IB Controls
1124    
1125    
1126 tony 33 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1127 tony 19
1128     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1129     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1130     Gabor Boros for reporting this problem and for testing the improvements).
1131    
1132     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1133     See readme.field+param.names in the doc folder.
1134    
1135     3. IBX SQL Editors will now automatically add double quotes around column names when the database
1136     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1137    
1138     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1139    
1140     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1141     actions.
1142    
1143     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1144     thanks to Yuriy Kopnin for pointing this out).
1145    
1146     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1147    
1148     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1149     for both fields and parameter setting.
1150    
1151     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1152     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1153    
1154     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1155     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1156    
1157     11. TIBTable now has a property editor for "MasterFields"
1158    
1159     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1160     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1161    
1162     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1163     of settings is unrecognised. Selecting this radio button has no effect on the settings.
1164

1171    
1172     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1173     it is null. This allows for alternative user defined setting of the generator
1174    
1175     Many thanks to Julio Jiménez for this fix
1176    
1177     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1178     and suggests that the user may have forgotten to install it.
1179

1181    
1182     1. Conditional compilation used to limit registration of TIntegerField to
1183     Lazarus versions less than 1.1
1184    
1185     2. When a database connection is created, character set is now by default set
1186     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1187     1250 to 1254.

1197     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1198     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1199    
1200     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1201     package is changed to do this (which it should do).
