2 >
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).
100 >
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.

109   1. IBExtract: Identity columns - add additional check for null column for generator name.
110  
# Line 15 | Line 121 | IBX Change Log  version
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 excuting a refresh query.
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.
# Line 75 | Line 181 | IBX Change Log  version
181   15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
182      for password on reconnect.
183  
184 < 16. IBDatabase: use IAttachment for connection default character set id, code page
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.
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.
