3 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
4 > all previous copies of the IBX source code tree before installing this release.
5 >
6 > The IBX packages used by most users have not changed, with one exception. The
7 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
8 > to use the IBServices unit in your applications, please add the iblegacyServices
9 > to the list of dependencies. To do this, open the Project Inspector and select
10 > Add->New Requirement and select "ibLegacyServices" from the list of available
11 > packages.
12 >
13 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
14 >   the IBServices unit providing what is intended to be a clearer and easier to
15 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
16 >   more information and the guide to "Firebird Service Management Using IBX".
17 >   As indicated above, the legacy services components are still available and
18 >   provided in a separate package. There is no need to update working applications
19 >   using the older versions except for an additional package dependency.
20 >
21 > 2. The IBX packages and source code tree have been re-organised in an attempt to
22 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
23 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
24 >   new set of IBX packages.
25 >
26 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
27 >   updated to use the new Services API components.
28 >
29 > 4. The iblocal package has been updated to use the new Services API components.
30 >
31 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
32 >   TIBXSecurityService. It had been wrongly classified in the previous version
33 >   as a per database configuration item. It is global to a server and hence
34 >   correctly positioned as part of the Security Package. In the DBAdmin example,
35 >   the setting has moved to the mappings page.
36 >
37 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
38 >   are ignored.
39 >
40 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
41 >   closed before the database is dropped. Before and After Disconnect event handlers
42 >   are also fired.
43 >
44 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
45 >   is started and not just the first time.
46 >
47 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
48 >   depenendency with comp type.
49 >
50 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
51 >
52 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
53 >    then this is recognised and not ignored.
54 >
55 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
56 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
57 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
58 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
59 >
60 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
61 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
62 >    counters for the select query. Note: stats accumulate after each fetch from
63 >    the database. To get total query cost after open, call the "Last" method
64 >    and then GetPerfStatistics.
65 >
66 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
67 >
68 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
69 >    in parenthesises.
70 >
71 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
72 >    SQL identifiers are always delimited by double quotes. If false, then they are
73 >    only delimited if the identifier is a reserved word, contains lower case or special
74 >    characters. Set this property to true to retain previous behaviour.
75 >
76 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
77 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
78 >
79 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
80 >       property MasterDetailDelay: integer {defaults to zero}
81 >
82 >    When non-zero and the dataset is a detail table referencing a master table
83 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
84 >    then a synchronisation delay is added (in milliseconds) between the master
85 >    row changing and the detail dataset being re-opened. If the master dataset
86 >    is scrolled before the delay expires then the delay is reset. This can be used
87 >    to avoid performance overheads when scrolling through a large master dataset.
88 >
89 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
90 >    chreads unit must be included in your project. TTimer is not used in order
91 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
92 >
93 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
94 >    with Extract Option eoDatabase.
95 >
96 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
97 >    When a deLaoutChanged event is reported on the ListSource dataset, the
98 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
99 >    relationship with the control's datasource (master).

101 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
102 >
103 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
104 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
105 > RELEASE.
106 >
107 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
108 >
109 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
110 >
111 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
112 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
113 >   information). However, this is also a very useful mechanism for returning updated computed by
114 >   column values. Values returned as a result of executing an Insert or Update statement
115 >   replace existing values in the current row for each corresponding column.
116 >
117 >   Previously, if a dataset's select query included read only (computed by) fields then
118 >   an automatic row refresh was performed after an insert or update query had been processed,
119 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
120 >   that an automatic refresh is no longer performed if an insert or update query contains
121 >   a returning clause that updates one or more fields on the current row. A full row
122 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
123 >   field values and the select query contains read only fields. Use of Insert/update
124 >   returning should be significantly more efficient than executing a refresh query.
125 >
126 >   This behaviour change is intended to be backwards compatible and there should be no need to change
127 >   existing programs, other than to improve performance by using the new capability.
128 >
129 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
130 >   they are called when the dataset row is being deleted, there is no value in
131 >   updating the current record from the query result. Instead, a new event handler
132 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
133 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
134 >   by the query. The event handler can then interrogate the query results and
135 >   perform whatever action is necessary. For example to confirm, to the user,
136 >   the deletion of a row with the returned values.
137 >
138 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
139 >   any Computed By or Identity Columns. The IBTables example has been updated to
140 >   illustrate the computation of the employee Full Name on update.
141 >
142 > 5. TIBTable: The GeneratorField property is now published.
143 >
144 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
145 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
146 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
147 >   each Identity column after the insert is executed.
148 >
149 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
150 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
151 >   Insert..Returning clause.
152 >
153 > 8. TIBGenerator: small performance improvement by not preparing query each time
154 >   a new value is generated.
155 >
156 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
157 >
158 > 10. Property editors will now sync table name to a System Table when "Include System
159 >    Tables" is selected and the query is for a System Table.
160 >
161 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
162 >    values are no longer converted to milliseconds from TDateTime and then back again
163 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
164 >
165 > 12. Property Editors handling of Stored Procedures.
166 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
167 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
168 >      query).
169 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
170 >
171 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
172 >    can be used to select a package. If non-empty, the stored procedure name is
173 >    expected to be a stored procedure defined in the specified package and the
174 >    generated SQL will be as required for a stored procedure located in a package.
175 >
176 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
177 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
178 >    which a stored procedure can be selected. With no package name selected, non-package
179 >    stored procedures are listed.
180 >
181 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
182 >    for password on reconnect.
183 >
184 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
185 >    and character set name.
186 >
187 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
188 >    DB info lookups"
189 >
190 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
191 >
192 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
193 >
194 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
195 >    parameters. This stops an exception being raised when the field cannot be
196 >    located in the record buffer.
197 >
198 > 21. Property Editors now automatically include System Tables when opened and when the query table
199 >    is a System Table.
200 >
201 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
202 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
203 >
204 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
205 >    add the SPB item isc_spb_expected_db. This names a database using
206 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
207 >    database. examples/services re-written to illustrate use of "expected_db".
208 >
209 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
210 >    This avoids truncated backups when the server returns a timeout (busy) response.
211 >
212 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
213 >
214 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
215 >    databasenames. These are respectively expanded to the local system's temp directory
216 >    (including trailing delimiter) or to a prescribed data directory (including
217 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
218 >    in the user's home directory. The hidden directory name is either the string returned
219 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
220 >    Under Windows, the directory is the same as the Data Directory as decribed
221 >    above but instead prefixed by the User's application data path. These may be
222 >    used to improve application portability for Personal Databases.
223 >
224 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
225 >    this has not worked for a long time and is not useful either. FieldDefs should be
226 >    managed using the Fields Editor as with any other dataset. To access the fields
227 >    editor for a TIBTable component, double click on the component. The fields editor
228 >    is then displayed.
229 >
230 > 28. TIBDatabaseInfo: new properties/function
231 >     * DateDBCreated (returns date/time database created)
232 >     * TransactionCount (returns no. of active transactions)
233 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
234 >     * PagesFree (Firebird 3 or later)
235 >     * PagesUsed (Firebird 3 or later)
236 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
237 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
238 >
239 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
240 >
241 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
242 >
243 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
244 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
245 >
246 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
247 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
248 >    firing during backup and restore.
249 >
250 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
251 >    for verbose output using the new property "StatisticsRequested".
252 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
253 >
254 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
255 >
256 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
257 >    palette. This uses the online validation feature added in Firebird 2.5. The
258 >    services's properties enable inclusion/exclusion of tables and indexes using
259 >    regular expressions. See.
260 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
261 >
262 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
263 >    option on a database.
264 >
265 > 37. TIBCustomService: Assign method implemented to allow copying of service login
266 >    context between service API components. "Detach" method now only detaches
267 >    service when last reference to the service interface detaches. Tidy up of
268 >    code for SetActive and Attach methods including password hiding.
269 >
270 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
271 >    and used to determine the auth method and protocol used for the connection.
272 >
273 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
274 >    a Create Database Statement generated by IBX.
275 >
276 > 40. All IBServices now have an additional published property "PortNo". This may
277 >    be set to a non-standard port number when necessary. If zero then the default
278 >    port number is used.
279 >
280 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
281 >    and not just the mouse.
282 >
283 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
284 >
285 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
286 >    image index and selected image index for each node to be set from a database field.
287 >
288 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
289 >    then database schema includes grants to all users. If not present then the
290 >    only user grants included are those to User PUBLIC.
291 >
292 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
293 >    and child nodes in dataset.
294 >

297 >
298 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
299 >   changes.
300 >
301 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
302 >   Bug could result in truncated multi-byte character set values.
303 >
304 > 3. Changes consequential on moving fbintf character set utility functions from
305 >   IFirebirdAPI to IAttachment.
306 >
307 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
308 >
309 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
310 >   results in autocomplete ignoring prefix text.
311 >
312 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
313 >   entering a new name into the text box.
314 >
315 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
316 >   Firebird rather than recomputing it.
317 >
318 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
319 >   screen centre. Previously some were "poDesigned" which may be inappropriate
320 >   for multi monitor desktops.
321 >
322 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
323 >
324 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
325 >    a transaction and always reset the object.
326 >
327 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
328 >
329 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
330 >
331 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
332 >    to a gbak format archive.
333 >
334 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
335 >
336 > 16. IBLocaldb: Drop database if error creating an empty database.
337 >
338 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
339 >    unless selected node not in current dataset.
340 >
341 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
342 >    to TIBCustomService, and IBlocalDB code tidy up.
343 >
344 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
345 >    behaviour due to uninitialised variable.
346 >
347 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
348 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
349 >
350 > 21. IBSQL: When Database changed ensure that all resources are freed.
351 >
352 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
353 >
354 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
355 >    * Line Wrap on SQL Token boundaries (on user command)
356 >    * auto-complete table names in drop down list of table names
357 >    * Double click on tablename or field name adds to SQL text
358 >
359 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
360 >
361 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
362 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
363 >    workaround for a problem in fpc 3.0.4 win64).
364 >
365 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
366 >
367 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.

371 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
372     include remote system name.
373  
374   2. TIBExtract: No longer include comment header and COMMIT statement for empty

383   5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
384  
385 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
386 +   that BindFields is called when the query is next activated. Avoids FieldName
387 +   not found error.
388 +
389 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
390 +   purpose and allows the programmer to define any action they want for Update, Insert
391 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
392 +   filtering of updates, or use of statements such as Grant or Revoke instead of
393 +   normal DML. See User Manual for more information.
