1 tony 270 IBX Change Log version (2.3-3 Build 11336) 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 267 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
74    
75 tony 263 1. Remove need to check for IsMultiThread by providing access to GUI timers via
76     IBGUIInterface. Note: master/detail delay timer does not apply to console
77     mode apps.
78    
79     2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
80     statement. This avoids problems if "Execute Block" is used as the Query.
81    
82     3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
83     internal SQL tokeniser routines.
84    
85     4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
86     as a select statement, with or without CTEs.
87    
88     5. IBSQLParser: parser now recognises the "ROWS" clause.
89    
90     6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
91     internal SQL tokeniser routines.
92    
93     7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
94     being raised for valid set statements processed by a data formatter.
95    
96     8. New published property for TIBDatabase and TIBXServicesConnection. This is
97     FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
98     the path of the Firebird Library used by the database/services connection.
99    
100     9. New read only public property for TIBDatabase and TIBXServicesConnection. This
101     is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
102     services connection.
103    
104     10.SQL Property editors now quote parameter names if "Quote identifier" is selected
105     or param name is not a valid SQL identifier.
106    
107     11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
108     view of whether the text box should be editable when no DataSource is specified.
109     TIBLookupComboEditBox has been updated to workaround this problem. As long as
110     ReadOnly is false, the text box is editable when no DataSource is specified.
111    
112     12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
113     the FBLIB environment variable. If you do not want to permit this then you
114     must modify the Register procedure in the design/IBDBReg.pas unit to remove
115     this setting.
116    
117 tony 241 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
118    
119     1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
120     Utf8EscapeControlChars
121    
122 tony 232 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
123 tony 101
124 tony 209 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
125     all previous copies of the IBX source code tree before installing this release.
126    
127     The IBX packages used by most users have not changed, with one exception. The
128     IBServices unit has been moved to the package iblegacyServices.lpk. To continue
129     to use the IBServices unit in your applications, please add the iblegacyServices
130     to the list of dependencies. To do this, open the Project Inspector and select
131     Add->New Requirement and select "ibLegacyServices" from the list of available
132     packages.
133    
134     1. New unit IBXServices. The IBXServices unit is a re-architectured update of
135     the IBServices unit providing what is intended to be a clearer and easier to
136     use set of IB Services components. See Chapter 10 of the IBX User Guide for
137     more information and the guide to "Firebird Service Management Using IBX".
138     As indicated above, the legacy services components are still available and
139     provided in a separate package. There is no need to update working applications
140     using the older versions except for an additional package dependency.
141    
142     2. The IBX packages and source code tree have been re-organised in an attempt to
143     finally get rid of the "duplicate ppu" warnings. This re-organisation should
144     not affect existing users. Section 2.3 of the IBX User Guide describes the
145     new set of IBX packages.
146    
147     3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
148     updated to use the new Services API components.
149    
150     4. The iblocal package has been updated to use the new Services API components.
151    
152     5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
153     TIBXSecurityService. It had been wrongly classified in the previous version
154     as a per database configuration item. It is global to a server and hence
155     correctly positioned as part of the Security Package. In the DBAdmin example,
156     the setting has moved to the mappings page.
157    
158     6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
159     are ignored.
160    
161     7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
162     closed before the database is dropped. Before and After Disconnect event handlers
163     are also fired.
164    
165     8. TIBTransaction: OnStartTransaction event now fires every time the transaction
166     is started and not just the first time.
167    
168     9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
169     depenendency with comp type.
170    
171     10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
172    
173     11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
174     then this is recognised and not ignored.
175    
176     12. TIBDataSet, TIBQuery, TIBTable: additions:
177     function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
178     function GetPerfStatistics(var stats: TPerfCounters): boolean;
179     property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
180    
181     GetRowsAffected returns the affected row counts from the last insert/update/delete
182     if EnableStatistics = true then GetPerfStatistics returns the current stats
183     counters for the select query. Note: stats accumulate after each fetch from
184     the database. To get total query cost after open, call the "Last" method
185     and then GetPerfStatistics.
186    
187     See ibx/examples/consolemode for an example of the use of GetPerfStatistics
188    
189     13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
190     in parenthesises.
191    
192     14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
193     SQL identifiers are always delimited by double quotes. If false, then they are
194     only delimited if the identifier is a reserved word, contains lower case or special
195     characters. Set this property to true to retain previous behaviour.
196    
197     15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
198     are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
199    
200     16. TIBDataSet, TIBQuery, TIBTable: addition:
201     property MasterDetailDelay: integer {defaults to zero}
202    
203     When non-zero and the dataset is a detail table referencing a master table
204     through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
205     then a synchronisation delay is added (in milliseconds) between the master
206     row changing and the detail dataset being re-opened. If the master dataset
207     is scrolled before the delay expires then the delay is reset. This can be used
208     to avoid performance overheads when scrolling through a large master dataset.
209    
210     Note: uses fptimer and hence requires a thread manager. Under Linux the
211     chreads unit must be included in your project. TTimer is not used in order
212 tony 213 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
213 tony 209
214     17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
215     with Extract Option eoDatabase.
216    
217     18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
218 tony 225 When a deLayoutChanged event is reported on the ListSource dataset, the
219 tony 209 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
220     relationship with the control's datasource (master).
221    
222 tony 221 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
223    
224 tony 226 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
225 tony 221 stubs. Pedantic fix really, as procedures output in dependency order anyway.
226    
227 tony 226 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
228 tony 221 DDL (Firebird 3 and later only).
229    
230 tony 225 22. TIBLookupComboBox Autocomplete Fixes:
231     i. Only appended text is now selected after autocomplete.
232     ii. Uppercase keys no longer ignored for autocomplete.
233     iii. Retain Prefix case is now honoured correctly.
234     iv. When a DataSource is assigned, typing after autocomplete now extends prefix
235     before autocomplete performed. i.e. behaviour now the same as when
236     no DataSource assigned.
237    
238 tony 226 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
239 tony 225 between SQL statements.
240    
241     24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
242     ObjectNames are converted to upper case before matching against metadata object
243     names, unless the objectname is delimited by double quotes, in which case, the
244     double quotes are removed and the remaining string is used (unmodified) to match
245     against the metadata object name.
246    
247     If true then the ObjectName is used as is without modification and matched
248     against the metadata object name. No attempt is made to remove double quotes.
249    
250 tony 226 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
251     with eoTrigger, these extract types can be used to select only Database Triggers,
252     or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
253    
254 tony 227 26. TIBXScript: If an exception occurs during the processing of a statement, the
255     statement separate character is now reset to the default (';').
256    
257 tony 229 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
258    
259     28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
260     a commit or reconnect statement and instead activated only when next SQL statement
261     is executed.
262    
263     29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
264    
265     30. TIBXScript: case insensitive regex now used when matching statements instead of
266     converting statement to upper case.
267    
268     31. TIBExtract: metadata comments now supported. New published property
269     IncludeMetaDataComments (default true). If true then metadata comments included
270     in extracted DDL. New Extract Object member eoComments. This may be used with
271     ExtractObject method to list all metadata comments.
272    
273     32. TIBExtract: ListObjectNames method added.
274    
275 tony 231 33. Updated Database component editor to support additional connection string
276     types.
277    
278 tony 209 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
279    
280 tony 151 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
281 tony 152 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
282 tony 151 RELEASE.
283    
284     NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
285    
286 tony 107 1. IBExtract: Identity columns - add additional check for null column for generator name.
287 tony 101
288     2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
289     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
290 tony 107 information). However, this is also a very useful mechanism for returning updated computed by
291     column values. Values returned as a result of executing an Insert or Update statement
292     replace existing values in the current row for each corresponding column.
293 tony 101
294 tony 107 Previously, if a dataset's select query included read only (computed by) fields then
295     an automatic row refresh was performed after an insert or update query had been processed,
296     irrespective of the setting of the "ForcedUpdates" property. This has changed such
297     that an automatic refresh is no longer performed if an insert or update query contains
298     a returning clause that updates one or more fields on the current row. A full row
299     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
300     field values and the select query contains read only fields. Use of Insert/update
301 tony 123 returning should be significantly more efficient than executing a refresh query.
302 tony 107
303     This behaviour change is intended to be backwards compatible and there should be no need to change
304     existing programs, other than to improve performance by using the new capability.
305    
306 tony 118 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
307     they are called when the dataset row is being deleted, there is no value in
308     updating the current record from the query result. Instead, a new event handler
309     "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
310     an OnDeleteReturning event handler is provided then it is called with the IResults returned
311     by the query. The event handler can then interrogate the query results and
312     perform whatever action is necessary. For example to confirm, to the user,
313     the deletion of a row with the returned values.
314    
315     4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
316 tony 107 any Computed By or Identity Columns. The IBTables example has been updated to
317     illustrate the computation of the employee Full Name on update.
318    
319 tony 118 5. TIBTable: The GeneratorField property is now published.
320 tony 107
321 tony 118 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
322 tony 101 When InsertSQL is generated, the Identity columns are not included in the list of values to
323     be inserted. A RETURNING clause is added to the insert statement to return the value of
324     each Identity column after the insert is executed.
325    
326 tony 118 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
327 tony 107 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
328     Insert..Returning clause.
329 tony 104
330 tony 118 8. TIBGenerator: small performance improvement by not preparing query each time
331 tony 107 a new value is generated.
332 tony 104
333 tony 118 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
334 tony 107
335 tony 118 10. Property editors will now sync table name to a System Table when "Include System
336     Tables" is selected and the query is for a System Table.
337 tony 105
338 tony 118 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
339 tony 107 values are no longer converted to milliseconds from TDateTime and then back again
340     to TDateTime (the conversion to milliseconds is the default TDataset approach).
341 tony 105
342 tony 118 12. Property Editors handling of Stored Procedures.
343 tony 107 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
344     which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
345     query).
346     * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
347 tony 106
348 tony 118 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
349 tony 107 can be used to select a package. If non-empty, the stored procedure name is
350     expected to be a stored procedure defined in the specified package and the
351     generated SQL will be as required for a stored procedure located in a package.
352    
353 tony 118 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
354 tony 107 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
355     which a stored procedure can be selected. With no package name selected, non-package
356     stored procedures are listed.
357    
358 tony 118 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
359 tony 109 for password on reconnect.
360 tony 107
361 tony 143 16. TIBDatabase: use IAttachment for connection default character set id, code page
362 tony 118 and character set name.
363 tony 109
364 tony 118 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
365     DB info lookups"
366    
367 tony 143 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
368 tony 118
369 tony 127 19. Add a property Editor for TIBUpdate.RefreshSQL.
370 tony 118
371 tony 139 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
372     parameters. This stops an exception being raised when the field cannot be
373     located in the record buffer.
374 tony 127
375 tony 141 21. Property Editors now automatically include System Tables when opened and when the query table
376     is a System Table.
377 tony 139
378 tony 150 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
379 tony 143 This avoids errors due to a stale SQRB or SRB being used for the next query.
380 tony 141
381 tony 143 23. IBServices: Service attach parameters now include "expected_db". This is used to
382     add the SPB item isc_spb_expected_db. This names a database using
383     an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
384     database. examples/services re-written to illustrate use of "expected_db".
385 tony 141
386 tony 143 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
387     This avoids truncated backups when the server returns a timeout (busy) response.
388    
389     25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
390    
391     26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
392     databasenames. These are respectively expanded to the local system's temp directory
393 tony 150 (including trailing delimiter) or to a prescribed data directory (including
394 tony 143 trailing delimiter). Under Unix systems the data directory is a hidden directory
395     in the user's home directory. The hidden directory name is either the string returned
396     from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
397     Under Windows, the directory is the same as the Data Directory as decribed
398     above but instead prefixed by the User's application data path. These may be
399 tony 150 used to improve application portability for Personal Databases.
400 tony 143
401     27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
402     this has not worked for a long time and is not useful either. FieldDefs should be
403     managed using the Fields Editor as with any other dataset. To access the fields
404     editor for a TIBTable component, double click on the component. The fields editor
405     is then displayed.
406    
407     28. TIBDatabaseInfo: new properties/function
408     * DateDBCreated (returns date/time database created)
409     * TransactionCount (returns no. of active transactions)
410     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
411     * PagesFree (Firebird 3 or later)
412     * PagesUsed (Firebird 3 or later)
413     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
414     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
415    
416     29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
417    
418     30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
419    
420     31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
421     the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
422    
423     32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
424     in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
425     firing during backup and restore.
426    
427     33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
428     for verbose output using the new property "StatisticsRequested".
429     see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
430    
431     34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
432    
433     35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
434     palette. This uses the online validation feature added in Firebird 2.5. The
435     services's properties enable inclusion/exclusion of tables and indexes using
436     regular expressions. See.
437     https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
438    
439     36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
440     option on a database.
441    
442     37. TIBCustomService: Assign method implemented to allow copying of service login
443     context between service API components. "Detach" method now only detaches
444     service when last reference to the service interface detaches. Tidy up of
445     code for SetActive and Attach methods including password hiding.
446    
447 tony 150 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
448 tony 143 and used to determine the auth method and protocol used for the connection.
449    
450     39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
451     a Create Database Statement generated by IBX.
452    
453     40. All IBServices now have an additional published property "PortNo". This may
454     be set to a non-standard port number when necessary. If zero then the default
455     port number is used.
456    
457     41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
458     and not just the mouse.
459    
460     42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
461    
462     43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
463     image index and selected image index for each node to be set from a database field.
464    
465     44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
466     then database schema includes grants to all users. If not present then the
467     only user grants included are those to User PUBLIC.
468    
469     45. TIBTreeView: performance improvement. When expanding include both expanded node
470     and child nodes in dataset.
471    
472    
473 tony 90 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
474 tony 56
475     1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
476     changes.
477    
478 tony 58 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
479     Bug could result in truncated multi-byte character set values.
480    
481 tony 60 3. Changes consequential on moving fbintf character set utility functions from
482     IFirebirdAPI to IAttachment.
483    
484 tony 62 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
485    
486 tony 64 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
487     results in autocomplete ignoring prefix text.
488    
489 tony 65 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
490     entering a new name into the text box.
491    
492 tony 66 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
493     Firebird rather than recomputing it.
494    
495 tony 67 8. Property Editor positioning tidy up: All IBX Property editors should now be
496     screen centre. Previously some were "poDesigned" which may be inappropriate
497     for multi monitor desktops.
498    
499 tony 80 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
500    
501     11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
502     a transaction and always reset the object.
503    
504     12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
505    
506     13. TIBXScript: Allow for override of database filename in Create Database statements.
507    
508     14. IBLocaldb: Support initialisation of the database from an SQL script in addition
509     to a gbak format archive.
510    
511     15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
512    
513     16. IBLocaldb: Drop database if error creating an empty database.
514    
515     17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
516     unless selected node not in current dataset.
517    
518     18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
519     to TIBCustomService, and IBlocalDB code tidy up.
520    
521     19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
522     behaviour due to uninitialised variable.
523    
524     20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
525     integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
526    
527     21. IBSQL: When Database changed ensure that all resources are freed.
528    
529     22. IBCustomDataset: When database changed ensure that queries an unprepared.
530    
531 tony 84 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
532     * Line Wrap on SQL Token boundaries (on user command)
533     * auto-complete table names in drop down list of table names
534     * Double click on tablename or field name adds to SQL text
535 tony 80
536     24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
537    
538     25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
539     TVariantArray. Seems to avoid memory corruption in Windows (probably a
540     workaround for a problem in fpc 3.0.4 win64).
541    
542     26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
543    
544 tony 83 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
545    
546 tony 51 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
547 tony 49
548 tony 51 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
549 tony 49 include remote system name.
550    
551     2. TIBExtract: No longer include comment header and COMMIT statement for empty
552     tables when data included in output.
553    
554     3. Profiling: IBSQL now has conditional compilation flags to enable query performance
555     and timing information to be written to stdout. This may be used to locate
556     performance bottlenecks.
557    
558     4. SQLParser: only call "OnChanging" event handler when value is different.
559    
560     5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
561    
562 tony 50 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
563     that BindFields is called when the query is next activated. Avoids FieldName
564     not found error.
565    
566 tony 80 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
567     purpose and allows the programmer to define any action they want for Update, Insert
568     or Delete. This may be complex SQL (similar to a Trigger), application specific
569     filtering of updates, or use of statements such as Grant or Revoke instead of
570     normal DML. See User Manual for more information.
571    
572 tony 47 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
573 tony 45
574 tony 47 1. TIBEvents: Fix uninitialised variable that could result in lost events.
575 tony 45
576 tony 47 2. TIBExtract: Added support for FB3 "USAGE" privilege.
577    
578     3. TIBExtract: data formatted as Charset set "octets" is now output using
579     hexadecimal notation.
580    
581     4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
582     using a simple XML format.
583    
584     5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
585     grants to these objects.
586    
587     6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
588     dependency problems restoring complex databases.
589    
590     7. TIBXScript: This component has been restructured to allow for the processing of
591     embedded XML in INSERT statements and to support interactive sources in addition
592     to non-interactive data sources such as files.
593    
594     8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
595    
596     9. TIBXScript: ISQL compatiable Set statements are now supported:
597     SET SQL DIALECT
598     SET TERM
599     SET AUTODDL
600     SET BAIL
601     SET ECHO
602     SET COUNT
603     SET STATS
604     SET NAMES <character set>
605    
606     10. IBVersion unit added to hold current IBX Version Number information.
607    
608     11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
609     and domain definitions.
610    
611     12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
612     fully supported.
613    
614     13. TIBExtract: when a database dump includes data, the generator values are now also set.
615    
616     14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
617    
618     IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
619    
620 tony 50 See also doc/IBX4LazarusGuide.pdf for important information on
621 tony 45 upgrading to IBX2.
622    
623     1. Size property of TIBStringField is now the width in characters of the field
624     and not the byte length. This applies only to multi-byte character sets such
625     as UTF8. The original approach aligned with TStringField. However, the TStringField
626     code is not recognised as a bug and hence this change to align the behaviour.
627     The TStringField change is expected in fpc 3.2.0.
628    
629     2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
630     true (default) then Size property value saved in the lfm is ignored. Size is
631     always set from the dynamic information read from the database. It is unclear
632     why anyone would want to override this and set Size to false.
633    
634     3. ibxscript: should now handle correctly a Case..End statement within a procedure
635     block.
636    
637     4. IBDatabase: new property - CreateIfNotExists. If true and database does not
638     exist when an attempt is made to connect to it (run time only) then an attempt
639     is made to create the database.
640    
641     5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
642     has been successfully created as a result of a call to CreateDatabase or when
643     creating a database after it was found not to exist.
644    
645     6. DBControlGrid: a race condition could result in the wrong row image being
646     written to the cache. This has been avoided by a trip round the message
647     loop before rendering the row image.
648    
649     7. DBControlGrid: It is strongly recommended not to open the source DataSet for
650     a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
651     known to risk corrupt rendering of row images when the control is first
652     displayed. If necessary use "Application.QueueAsyncCall" to delay opening
653     of the dataset (see DBControlGrid examples) until the Form's Window has been created.
654    
655     8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
656     a TDateEdit control located on an editor panel.
657    
658     9. TIBExtract: brought up-to-date plus many bug fixes.
659    
660     10. DBControlGrid: Removed memory leak when updating rows.
661    
662     11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
663    
664 tony 43 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
665    
666     1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
667     when target codepage is CP_NONE. This is a workaround for
668     http://bugs.freepascal.org/view.php?id=30622.
669    
670     2. DBLog option removed from TIBStatisticalService - not supported by server
671     since Firebird 1.5.
672    
673     3. ibxscript: An error is no longer generated for "on commit preserve rows" or
674     similar.
675    
676     4. IBCodePage: updated mapping between codepages and character id.
677    
678     5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
679     Firebird. Character sets with a char width of two are not UTF16.
680    
681     6. Strings received from the database are now always transliterated into UTF8
682     regardless of the database character set or connection character set. This
683     is for compatibility with the LCL.
684    
685 tony 45 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
686 tony 41
687     1. IBBlob: Defer reading of blob until read method called. This avoids having to
688     read in an entire blob just to get the size of the blob. General performance
689     improvement when opening datasets containing blobs.
690    
691     2. Clearing a Blob now sets the corresponding field's modified flag.
692    
693     3. IBLookupCombo: When not performing auto-complete, original query sort order
694     is now used.
695    
696     4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
697     determined.
698    
699     5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
700    
701     6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
702     lazarus 1.6.0
703    
704     7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
705     compilation error.
706    
707 tony 39 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
708    
709     1. No character set specified for connection: when a text blob is retrieved, the
710     character set is determined by looking up the native character set using then
711     Firebird API. Otherwise a text mode blob is assumed to have the same character
712     set as the connection.
713    
714     2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
715     for Login Dialog returing a change to the database path.
716    
717     3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
718     to be changed from that given in the TIBDatabase/TIBServer component and for the
719     entered value to be saved on a project specific basis (design time only).
720    
721     4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
722     column fieldname. If they are the same then it is acts as a look up for the KeyValue
723     Otherwise, it sets the column text to the selected ListField Value.
724    
725     5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
726     column width.
727    
728     6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
729     and a case insensitive search is requested.
730    
731     7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
732     or column ListSource.
733    
734     8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
735     unprepare) when closing and the text has not changed.
736    
737     9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
738     Less likely to cause a cursor re-use error on Windows.
739    
740     10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
741     Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
742    
743     11. TIBTreeView: Guard against nil destination on record changed
744    
745     12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
746     string type with the code page set to reflect the returned field encoding after
747     Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
748     earlier versions.
749    
750     13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
751     will now result in transliteration to the code page specified for the Firebird driver
752     if the assigned string has a different code page. FPC 3.0.0 onwards only.
753    
754     14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
755     is ignored and the lc_ctype value, when the database is opened, is set to align with
756     the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
757     platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
758     3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
759     the GETACP is used to determine the Windows code page.
760    
761     15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
762     name used as the lc_ctype when the database was opened. Only valid while the
763     Database is connected.
764    
765     16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
766     id that corresponds to the DefaultCharSetName.
767    
768 tony 37 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
769    
770     1. Unix: If Firebird Embedded Server shared object is loaded and a local database
771     path is given and database attach fails due to access permission issues on the
772     temp directory or security database, then the attach is retried with "localhost:"
773     prefixing the databasename. This should avoid problems when the database has to
774     be accessed by a local (e.g. classic) server and libfbembed is used.
775    
776     2. Windows: revised search order for Firebird DLL:
777     i. The Firebird Embedded Server in the application Directory.
778     ii. If the FIREBIRD environment variable is set then the directory this
779     points to is searched for the FB Client DLL and then then underlying
780     "bin" directory.
781     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
782     is used to locate the Firebird installation directory and the underlying
783     "bin" directory is searched for the FB Client DLL.
784     iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
785     are searched for the FB Client DLL.
786     v. The PATH Environment variable is used to search for the FB Client DLL.
787     vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
788    
789     3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
790     See doc/readme.scriptengine and example applications.
791    
792     4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
793     simplify the use of the embedded firebird server on both Linux and Windows platforms.
794     See dpc/readme.localdatabase and example applications.
795    
796     5. IBDynamicGrid: Reordering on column header click should now also work for
797     dynamic columns.
798    
799     6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
800     between incrementing/decrementing the lock count and signalling the event.
801    
802 tony 35 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
803    
804 tony 37 1.3.2 was never formally released and only made available as beta copies.
805    
806 tony 35 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
807    
808     2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
809    
810     3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
811    
812     4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
813     i.e. when it is a calculated field
814    
815     5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
816     This problem was due to a race condition between recalculating row heights and
817     determining which row was selected by the mouse click. The row height calculation
818     is now deferred by an extra trip round the message loop allowing the row to
819     be always calculated on the current grid layout rather than risking it being
820     calculated on the grid layout after the expanded row has been shrunk.
821    
822     6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
823     Windows.
824    
825     7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
826     These properties allow the (Firebird) character set name for the field and the max number of bytes per character
827 tony 37 to be determined at runtime. See doc/readme.charactersets.html.
828 tony 35
829     8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
830 tony 37 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
831 tony 35
832     9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
833     TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
834 tony 37 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
835 tony 35
836     Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
837     from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
838     implies no truncation.
839    
840     10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
841    
842     11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
843     (avoids "Not in Edit Mode" error).
844    
845     12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
846    
847     13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
848     DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
849    
850     14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
851    
852     15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
853    
854     16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
855    
856     17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
857

859 tony 31
860     1. OnCloseUp Event Handler added to TDBLookupProperties
861    
862     2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
863     problem with row size when exception is called.
864    
865     3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
866    
867     4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
868     in a TCustomComboBox and ignores return key if in a TCustomMemo
869    
870     5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
871     keyed in i.e. when autocomplete not performed
872    
873 tony 33 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
874     console mode applications with all LCL required functions (builtin dialogs and
875     cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
876     not included in your project, IBX should compile and link with a console mode program.
877     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
878     console mode application or the IDE will automatically assume that your
879     application is GUI based. Instead, you should include the ibexpressconsolemode package.
880 tony 31
881     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
882     to use the built in dialogs and cursor management. IBDialogs is
883 tony 33 included by default if "ibexpress" is in your project source's "uses" clause.
884 tony 31 This should be the case for all projects created through the IDE. This is why
885     you do not want to add the ibexpress package to console mode applications. The
886     ibexpressconsolemode package has been created to allow console mode programs
887     to avoid adding LCL dependencies when using IBX, while still having the
888     unit search paths set up correctly.
889    
890 tony 33 Existing users should check to ensure that the "ibexpress" unit is included in
891     each project's source file (*.lpr).
892    
893 tony 31 You may find that in order for the IDE to recognise that ibexpressconsolemode
894     exists, you have to first open the package in the IDE and then close it. This
895     adds it to the most recently accessed packages list. To make it permanently
896     available, add the package name to lazarus' staticpackages.inc file.
897    
898 tony 33 Thanks to Julio Jiménez for suggesting support of console mode.
899 tony 31
900     7. SQL Parser can now accept quoted strings that include new lines
901    
902     8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
903     of text on start of edit. This is particularly useful when tabbing to a
904     column and then inserting text.
905    
906     9. New Examples provided for IB Services and ISQLMonitor.
907    
908     10. Fix error when writing to blob streams that recorded only the last buffer
909     write in the blob stream. In most cases, this did not cause a problem as the
910     IB Blob Stream is written in a single write. However, with the TDBImage, write
911     of a graphic type prefix was lost which caused a problem when the image could
912     not be automatically recognised.
913    
914     11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
915 tony 33 already open" errors due to random numbers used for the cursor name being identical.
916 tony 31
917     12. IBTable: corrected error that could result in an "Index out of bounds" error
918     when opening the table and the Primary Key is the last or only column in the
919     table. Thanks to Rick Hoover for the fix.
920    
921 tony 33 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
922     of "UTF-8", and update list of available database character sets. Existing
923     users should check the current lc_ctype setting in their applications.

925 tony 33 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
926    
927 tony 29 1. Firebird Services: avoid List Index error when opening a service with an
928     empty Params property.
929    
930     2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
931     Link now set up in Loaded method - avoids occasional failure to apply
932     SQL markup on initial open.
933    
934     3. "Employees" example performance improvements when scrolling.
935    
936     4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
937     TFrame. Force recaching of selected frame to avoid GTK race (results in a
938     random image cached).
939    
940     5. DBControlGrid: Should now react to changes in panel height at run time.
941    
942     6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
943     even when further rows exist.
944    
945     7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
946     always be derived from panel height and setting this property can cause confusion.
947     Note for existing projects: to avoid a missing property error at run time,
948     each form using the DBControlGrid must be opened, updated and saved in the IDE
949     in order to remove the property value from the lfm.
950    
951    
952 tony 33 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
953 tony 27
954     1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
955     call Prepare before setting parameter values.
956    
957     2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
958    
959     3. Code tidyup and more robust handling of dsql information result vector.
960    
961     4. Support for centralised handling of transaction status changes. TIBTransaction
962     has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
963     and "AfterExecQuery". The first three are called after the same event is called
964     for an IBCustomDataSet descendent using the Transaction. The fourth is called
965     after a call to TIBSQL.ExecQuery, again using this transaction. These new events
966     enable monitoring of transaction status changes for a given transaction to be
967     handled in a single place. For example, when a change to the dataset occurs
968     an indicator can be set that shows the user that in order to save changes,
969     the transaction should be committed. Rather than doing this per dataset, this
970     can now be done per transaction.
971    
972     5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
973     the dataset is scrolled. However, any changes to the current row are, by default,
974     discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
975     have a new property "DataSetCloseAction" that adds automatic posting of changes
976     on dataset close. If this property is set to dcDiscardChanges (default) then the
977     behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
978     then IBX will attempt to post any unsaved changes before the dataset is closed
979     (and after the BeforeClose event handler is called). The exception is when the
980     dataset is being closed as a result of a transaction rollback. In this case,
981     no action is taken and any unsaved changes are discarded. This avoids both
982     unnecessary overhead and the risk that a validation error may occur in the Post
983     raising an exception and thereby preventing a rollback.
984    
985     6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
986     In earlier versions, the Display Width was set to the maximum byte width rather than the character
987     width. Display Widths are now corrected by dividing by the max byte width per character.
988     For UTF8 character sets, the byte width is four and hence the Display Width will be
989     the byte width divided by 4. The byte width of each character set is determined
990     dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
991     system table. (see also http://bugs.freepascal.org/view.php?id=27766).
992    
993     7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
994    
995     8. IBLookupComboEditBox: List should now always be restored to full list when the
996     control loses focus. Default Key press default interval reduced to 200ms.
997    
998     9. DBControlGrid: Ensure that selection is changed to newly appended row, even
999     when dataset rows are less than visible rows.
1000    
1001     10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1002     does not exist or DataSet is empty. More responsive on dataset open. New event
1003     OnRestorePosition. Column sort disabled if no header row.
1004    
1005     11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1006     while dataset state is dsInsert. Avoids posting errors.
1007    
1008     12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1009     avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1010    
1011     13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1012    
1013     14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1014     to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1015     a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1016     always "posts" the current record regardless or whether or not it may be more appropriate
1017     to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1018     "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1019     as the first action of the "Post" method and allows the handler to convert the Post
1020     into a Cancel if that is the appropriate action on moving to a different row. This is
1021     achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1022     raised here, but it may still be more appropriate to validate a post and signal
1023     a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1024    
1025     15. On Unix derived systems, the Firebird library name can now be given as a colon
1026     separated list. Each library name on the list is tried in turn, in left to right
1027     order with the first found being used as the firebird library. By default, on Linux,
1028     the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1029     overidden by the FBLIB environment variable or the OnGetLibraryName function.
1030    
1031     Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1032     then it will still attempt to access the database via the Firebird Server and will
1033     require a username and password. If only the pathname is given, then the username
1034     and password should be omitted and the unix file permissions are used to grant
1035     access.
1036    
1037 tony 33 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1038 tony 23
1039     1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1040     rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1041     that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1042 tony 27 corresponds to a row of the linked DataSource. Any data aware control on the
1043 tony 23 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1044    
1045     2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1046 tony 25 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1047 tony 23 takes place during database access. This may be useful when there are performance issues with
1048     the change of cursor. Setting the property to false suppresses the change of cursor.
1049    
1050     3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1051     and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1052     Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1053     making all changes permanent immediately rather than when the transaction is explicitly
1054     committed.
1055    
1056 tony 25 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1057 tony 27 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

1064 tony 21
1065     1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1066     This is typically used during an "OnBeforeOpen" event handler to manipulate the
1067     "Where" and "Having" clauses to implement user specified filters of arbitrary
1068     complexity.
1069    
1070     2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1071     three new data aware controls dependent on IBX and which make use of the SQL Parser.
1072     These are:
1073    
1074     - TIBLookupComboEditBox
1075     - TIBDynamicGrid
1076     - TIBTreeview
1077    
1078     TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1079     of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1080     to revise the available list and restrict it to items that are prefixed by the
1081 tony 25 typed text (either case sensitive or case insensitive). Autoinsert allows a
1082 tony 21 newly typed entry to be added to the list dataset and included in the available
1083     list items.
1084    
1085     TIBDynamicGrid is a TDBGrid descendent that provides for:
1086     - automatic resizing of selected columns to fill the available row length
1087     - automatic positioning and sizing of a "totals" control, typically at the
1088     column footer, on a per column basis.
1089     - DataSet resorting on header row click, sorting the dataset by the selected column.
1090     A second click on the same header cell reversed the sort order.
1091     - Support for a "Panel Editor". That is on clicking the indicator column, the row
1092     is automatically expanded and a panel superimposed on it. The panel can have any
1093     number of child controls, typically data aware controls with the same datasource
1094     as the grid allowing for editing of additional fields and more complex editors.
1095     - Reselection of the same row following resorting.
1096     - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1097     Its properties are specified on a per column basis and allows for one or more
1098     columns to have their values selected from a list provided by a dataset.
1099     Autocomplete and autoinsert are also available. The existing picklist editor
1100     is unaffected by the extension.
1101    
1102     TIBTreeView is a data aware TCustomTreeView.
1103    
1104     3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1105     zero scale will no longer return an error. An Int64 will be returned instead.
1106    
1107     4. TIBTransaction now has events for Before and After Transaction End and a new function
1108     "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1109    
1110     5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1111     repeated multiple times.
1112    
1113     6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1114     check used to get in the way of using Stored Procedures, and "Update or Insert"
1115     statements.
1116    
1117     7. Insert, Modify and Delete property Editors now support Query Generation from
1118     Stored Procedures.
1119    
1120     8. Three new examples illustrate the use of the new IB Controls
1121

1124 tony 19
1125     1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1126     setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1127     Gabor Boros for reporting this problem and for testing the improvements).
1128    
1129     2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1130     See readme.field+param.names in the doc folder.
1131    
1132     3. IBX SQL Editors will now automatically add double quotes around column names when the database
1133     dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1134    
1135     4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1136    
1137     5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1138     actions.
1139    
1140     6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1141     thanks to Yuriy Kopnin for pointing this out).
1142    
1143     7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1144    
1145     8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1146     for both fields and parameter setting.
1147    
1148     9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1149     visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1150    
1151     10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1152     when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1153    
1154     11. TIBTable now has a property editor for "MasterFields"
1155    
1156     12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1157     GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1158    
1159     13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1160     of settings is unrecognised. Selecting this radio button has no effect on the settings.
1161

1168    
1169     1. In a TIBCustomDataset descendent, a generator now only sets the value when
1170     it is null. This allows for alternative user defined setting of the generator
1171    
1172     Many thanks to Julio Jiménez for this fix
1173    
1174     2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1175     and suggests that the user may have forgotten to install it.
1176

1179     1. Conditional compilation used to limit registration of TIntegerField to
1180     Lazarus versions less than 1.1
1181    
1182     2. When a database connection is created, character set is now by default set
1183     to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1184     1250 to 1254.

1194     1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1195     Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1196    
1197     2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1198     package is changed to do this (which it should do).
