2 >
3 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
4 > AVOID DUPLICATE PPU ERRORS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
5 > RELEASE.
6 >
7 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
8 >
9 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
10 >
11 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
12 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
13 >   information). However, this is also a very useful mechanism for returning updated computed by
14 >   column values. Values returned as a result of executing an Insert or Update statement
15 >   replace existing values in the current row for each corresponding column.
16 >
17 >   Previously, if a dataset's select query included read only (computed by) fields then
18 >   an automatic row refresh was performed after an insert or update query had been processed,
19 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
20 >   that an automatic refresh is no longer performed if an insert or update query contains
21 >   a returning clause that updates one or more fields on the current row. A full row
22 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
23 >   field values and the select query contains read only fields. Use of Insert/update
24 >   returning should be significantly more efficient than executing a refresh query.
25 >
26 >   This behaviour change is intended to be backwards compatible and there should be no need to change
27 >   existing programs, other than to improve performance by using the new capability.
28 >
29 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
30 >   they are called when the dataset row is being deleted, there is no value in
31 >   updating the current record from the query result. Instead, a new event handler
32 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
33 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
34 >   by the query. The event handler can then interrogate the query results and
35 >   perform whatever action is necessary. For example to confirm, to the user,
36 >   the deletion of a row with the returned values.
37 >
38 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
39 >   any Computed By or Identity Columns. The IBTables example has been updated to
40 >   illustrate the computation of the employee Full Name on update.
41 >
42 > 5. TIBTable: The GeneratorField property is now published.
43 >
44 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
45 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
46 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
47 >   each Identity column after the insert is executed.
48 >
49 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
50 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
51 >   Insert..Returning clause.
52 >
53 > 8. TIBGenerator: small performance improvement by not preparing query each time
54 >   a new value is generated.
55 >
56 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
57 >
58 > 10. Property editors will now sync table name to a System Table when "Include System
59 >    Tables" is selected and the query is for a System Table.
60 >
61 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
62 >    values are no longer converted to milliseconds from TDateTime and then back again
63 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
64 >
65 > 12. Property Editors handling of Stored Procedures.
66 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
67 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
68 >      query).
69 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
70 >
71 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
72 >    can be used to select a package. If non-empty, the stored procedure name is
73 >    expected to be a stored procedure defined in the specified package and the
74 >    generated SQL will be as required for a stored procedure located in a package.
75 >
76 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
77 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
78 >    which a stored procedure can be selected. With no package name selected, non-package
79 >    stored procedures are listed.
80 >
81 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
82 >    for password on reconnect.
83 >
84 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
85 >    and character set name.
86 >
87 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
88 >    DB info lookups"
89 >
90 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
91 >
92 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
93 >
94 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
95 >    parameters. This stops an exception being raised when the field cannot be
96 >    located in the record buffer.
97 >
98 > 21. Property Editors now automatically include System Tables when opened and when the query table
99 >    is a System Table.
100 >
101 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
102 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
103 >
104 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
105 >    add the SPB item isc_spb_expected_db. This names a database using
106 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
107 >    database. examples/services re-written to illustrate use of "expected_db".
108 >
109 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
110 >    This avoids truncated backups when the server returns a timeout (busy) response.
111 >
112 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
113 >
114 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
115 >    databasenames. These are respectively expanded to the local system's temp directory
116 >    (including trailing delimiter) or to a prescribed data directory (including
117 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
118 >    in the user's home directory. The hidden directory name is either the string returned
119 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
120 >    Under Windows, the directory is the same as the Data Directory as decribed
121 >    above but instead prefixed by the User's application data path. These may be
122 >    used to improve application portability for Personal Databases.
123 >
124 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
125 >    this has not worked for a long time and is not useful either. FieldDefs should be
126 >    managed using the Fields Editor as with any other dataset. To access the fields
127 >    editor for a TIBTable component, double click on the component. The fields editor
128 >    is then displayed.
129 >
130 > 28. TIBDatabaseInfo: new properties/function
131 >     * DateDBCreated (returns date/time database created)
132 >     * TransactionCount (returns no. of active transactions)
133 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
134 >     * PagesFree (Firebird 3 or later)
135 >     * PagesUsed (Firebird 3 or later)
136 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
137 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
138 >
139 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
140 >
141 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
142 >
143 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
144 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
145 >
146 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
147 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
148 >    firing during backup and restore.
149 >
150 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
151 >    for verbose output using the new property "StatisticsRequested".
152 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
153 >
154 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
155 >
156 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
157 >    palette. This uses the online validation feature added in Firebird 2.5. The
158 >    services's properties enable inclusion/exclusion of tables and indexes using
159 >    regular expressions. See.
160 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
161 >
162 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
163 >    option on a database.
164 >
165 > 37. TIBCustomService: Assign method implemented to allow copying of service login
166 >    context between service API components. "Detach" method now only detaches
167 >    service when last reference to the service interface detaches. Tidy up of
168 >    code for SetActive and Attach methods including password hiding.
169 >
170 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
171 >    and used to determine the auth method and protocol used for the connection.
172 >
173 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
174 >    a Create Database Statement generated by IBX.
175 >
176 > 40. All IBServices now have an additional published property "PortNo". This may
177 >    be set to a non-standard port number when necessary. If zero then the default
178 >    port number is used.
179 >
180 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
181 >    and not just the mouse.
182 >
183 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
184 >
185 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
186 >    image index and selected image index for each node to be set from a database field.
187 >
188 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
189 >    then database schema includes grants to all users. If not present then the
190 >    only user grants included are those to User PUBLIC.
191 >
192 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
193 >    and child nodes in dataset.
194 >
195 >
196 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
197 >
198 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
199 >   changes.
200 >
201 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
202 >   Bug could result in truncated multi-byte character set values.
203 >
204 > 3. Changes consequential on moving fbintf character set utility functions from
205 >   IFirebirdAPI to IAttachment.
206 >
207 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
208 >
209 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
210 >   results in autocomplete ignoring prefix text.
211 >
212 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
213 >   entering a new name into the text box.
214 >
215 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
216 >   Firebird rather than recomputing it.
217 >
218 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
219 >   screen centre. Previously some were "poDesigned" which may be inappropriate
220 >   for multi monitor desktops.
221 >
222 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
223 >
224 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
225 >    a transaction and always reset the object.
226 >
227 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
228 >
229 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
230 >
231 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
232 >    to a gbak format archive.
233 >
234 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
235 >
236 > 16. IBLocaldb: Drop database if error creating an empty database.
237 >
238 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
239 >    unless selected node not in current dataset.
240 >
241 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
242 >    to TIBCustomService, and IBlocalDB code tidy up.
243 >
244 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
245 >    behaviour due to uninitialised variable.
246 >
247 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
248 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
249 >
250 > 21. IBSQL: When Database changed ensure that all resources are freed.
251 >
252 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
253 >
254 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
255 >    * Line Wrap on SQL Token boundaries (on user command)
256 >    * auto-complete table names in drop down list of table names
257 >    * Double click on tablename or field name adds to SQL text
258 >
259 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
260 >
261 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
262 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
263 >    workaround for a problem in fpc 3.0.4 win64).
264 >
265 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
266 >
267 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
268 >
269 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
270 >
271 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
272 >   include remote system name.
273 >
274 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
275 >   tables when data included in output.
276 >
277 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
278 >   and timing information to be written to stdout. This may be used to locate
279 >   performance bottlenecks.
280 >
281 > 4. SQLParser: only call "OnChanging" event handler when value is different.
282 >
283 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
284 >
285 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
286 >   that BindFields is called when the query is next activated. Avoids FieldName
287 >   not found error.
288 >
289 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
290 >   purpose and allows the programmer to define any action they want for Update, Insert
291 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
292 >   filtering of updates, or use of statements such as Grant or Revoke instead of
293 >   normal DML. See User Manual for more information.
294 >
295 > IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
296 >
297 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
298 >
299 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
300 >
301 > 3. TIBExtract: data formatted as Charset set "octets" is now output using
302 >   hexadecimal notation.
303 >
304 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
305 >   using a simple XML format.
306 >
307 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
308 >   grants to these objects.
309 >
310 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
311 >   dependency problems restoring complex databases.
312 >
313 > 7. TIBXScript: This component has been restructured to allow for the processing of
314 >   embedded XML in INSERT statements and to support interactive sources in addition
315 >   to non-interactive data sources such as files.
316 >
317 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
318 >
319 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
320 >   SET SQL DIALECT
321 >   SET TERM
322 >   SET AUTODDL
323 >   SET BAIL
324 >   SET ECHO
325 >   SET COUNT
326 >   SET STATS
327 >   SET NAMES <character set>
328 >
329 > 10. IBVersion unit added to hold current IBX Version Number information.
330 >
331 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
332 >    and domain definitions.
333 >
334 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
335 >    fully supported.
336 >
337 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
338 >
339 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
340 >
341 > IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
342 >
343 > See also doc/IBX4LazarusGuide.pdf for important information on
344 > upgrading to IBX2.
345 >
346 > 1. Size property of TIBStringField is now the width in characters of the field
347 >   and not the byte length. This applies only to multi-byte character sets such
348 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
349 >   code is not recognised as a bug and hence this change to align the behaviour.
350 >   The TStringField change is expected in fpc 3.2.0.
351 >
352 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
353 >   true (default) then Size property value saved in the lfm is ignored. Size is
354 >   always set from the dynamic information read from the database. It is unclear
355 >   why anyone would want to override this and set Size to false.
356 >
357 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
358 >   block.
359 >
360 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
361 >   exist when an attempt is made to connect to it (run time only) then an attempt
362 >   is made to create the database.
363 >
364 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
365 >   has been successfully created as a result of a call to CreateDatabase or when
366 >   creating a database after it was found not to exist.
367 >
368 > 6.  DBControlGrid: a race condition could result in the wrong row image being
369 >    written to the cache. This has been avoided by a trip round the message
370 >    loop before rendering the row image.
371 >
372 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
373 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
374 >    known to risk corrupt rendering of row images when the control is first
375 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
376 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
377 >
378 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
379 >    a TDateEdit control located on an editor panel.
380 >
381 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
382 >
383 > 10. DBControlGrid: Removed memory leak when updating rows.
384 >
385 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

388 >
389 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
390 >   when target codepage is CP_NONE. This is a workaround for
391 >   http://bugs.freepascal.org/view.php?id=30622.
392 >
393 > 2. DBLog option removed from TIBStatisticalService - not supported by server
394 >   since Firebird 1.5.
395 >
396 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
397 >   similar.
398 >
399 > 4. IBCodePage: updated mapping between codepages and character id.
400 >
401 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
402 >   Firebird. Character sets with a char width of two are not UTF16.
403 >
404 > 6. Strings received from the database are now always transliterated into UTF8
405 >   regardless of the database character set or connection character set. This
406 >   is for compatibility with the LCL.

409  
410   1. IBBlob: Defer reading of blob until read method called. This avoids having to
411     read in an entire blob just to get the size of the blob. General performance
