Please remove +all previous copies of the IBX source code tree before installing this release. + +The IBX packages used by most users have not changed, with one exception. The +IBServices unit has been moved to the package iblegacyServices.lpk. To continue +to use the IBServices unit in your applications, please add the iblegacyServices +to the list of dependencies. To do this, open the Project Inspector and select +Add->New Requirement and select "ibLegacyServices" from the list of available +packages. + +1. New unit IBXServices. The IBXServices unit is a re-architectured update of + the IBServices unit providing what is intended to be a clearer and easier to + use set of IB Services components. See Chapter 10 of the IBX User Guide for + more information and the guide to "Firebird Service Management Using IBX". + As indicated above, the legacy services components are still available and + provided in a separate package. There is no need to update working applications + using the older versions except for an additional package dependency. + +2. The IBX packages and source code tree have been re-organised in an attempt to + finally get rid of the "duplicate ppu" warnings. This re-organisation should + not affect existing users. Section 2.3 of the IBX User Guide describes the + new set of IBX packages. + +3. The ibx/examples/DBAdmin and the ibx/examples/services example have been + updated to use the new Services API components. + +4. The iblocal package has been updated to use the new Services API components. + +5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of + TIBXSecurityService. It had been wrongly classified in the previous version + as a per database configuration item. It is global to a server and hence + correctly positioned as part of the Security Package. In the DBAdmin example, + the setting has moved to the mappings page. + +6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements + are ignored. + +7. TIBDatabase: DropDatabase now ensures that all transactions have been properly + closed before the database is dropped. Before and After Disconnect event handlers + are also fired. + +8. TIBTransaction: OnStartTransaction event now fires every time the transaction + is started and not just the first time. + +9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform + depenendency with comp type. + +10. IBDataOutput: select query data output is now sent to stdout instead of stderr. + +11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName + then this is recognised and not ignored. + +12. TIBDataSet, TIBQuery, TIBTable: additions: + function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean; + function GetPerfStatistics(var stats: TPerfCounters): boolean; + property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics; + + GetRowsAffected returns the affected row counts from the last insert/update/delete + if EnableStatistics = true then GetPerfStatistics returns the current stats + counters for the select query. Note: stats accumulate after each fetch from + the database. To get total query cost after open, call the "Last" method + and then GetPerfStatistics. + + See ibx/examples/consolemode for an example of the use of GetPerfStatistics + +13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated + in parenthesises. + +14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3 + SQL identifiers are always delimited by double quotes. If false, then they are + only delimited if the identifier is a reserved word, contains lower case or special + characters. Set this property to true to retain previous behaviour. + +15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names + are now inserted in double quotes if not Reserved Words or valid SQL Identifiers. + +16. TIBDataSet, TIBQuery, TIBTable: addition: + property MasterDetailDelay: integer {defaults to zero} + + When non-zero and the dataset is a detail table referencing a master table + through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery) + then a synchronisation delay is added (in milliseconds) between the master + row changing and the detail dataset being re-opened. If the master dataset + is scrolled before the delay expires then the delay is reset. This can be used + to avoid performance overheads when scrolling through a large master dataset. + + Note: uses fptimer and hence requires a thread manager. Under Linux the + chreads unit must be included in your project. TTimer is not used in order + to avoid an LCL dependency. Requires FPC 3.0.2 or later. + +17. TIBExtract: User role grants now excluded when etGrantsToUser not specified + with Extract Option eoDatabase. + +18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428 + When a deLaoutChanged event is reported on the ListSource dataset, the + combobox text is updated. This allows a listsource (detail) to be in a Master/Detail + relationship with the control's datasource (master). + +IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000 + +NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1.

IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input + parameters. This stops an exception being raised when the field cannot be + located in the record buffer. + +21. Property Editors now automatically include System Tables when opened and when the query table + is a System Table. + +22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception. + This avoids errors due to a stale SQRB or SRB being used for the next query. + +23. IBServices: Service attach parameters now include "expected_db". This is used to + add the SPB item isc_spb_expected_db. This names a database using + an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a + database. examples/services re-written to illustrate use of "expected_db". + +24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout. + This avoids truncated backups when the server returns a timeout (busy) response. + +25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase. + +26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local + databasenames. These are respectively expanded to the local system's temp directory + (including trailing delimiter) or to a prescribed data directory (including + trailing delimiter). Under Unix systems the data directory is a hidden directory + in the user's home directory. The hidden directory name is either the string returned + from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'. + Under Windows, the directory is the same as the Data Directory as decribed + above but instead prefixed by the User's application data path. These may be + used to improve application portability for Personal Databases. + +27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef + this has not worked for a long time and is not useful either. FieldDefs should be + managed using the Fields Editor as with any other dataset. To access the fields + editor for a TIBTable component, double click on the component. The fields editor + is then displayed. + +28. TIBDatabaseInfo: new properties/function + * DateDBCreated (returns date/time database created) + * TransactionCount (returns no. of active transactions) + * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only). + * PagesFree (Firebird 3 or later) + * PagesUsed (Firebird 3 or later) + * Encrypted (returns true if database encrypted.

IBServices classes now provided the decoded release number in the (array) property ServerVersionNo. + +30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later). + +31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable + the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later). + +32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced + in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from + firing during backup and restore. + +33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options + for verbose output using the new property "StatisticsRequested". + see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats + +34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later). + +35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin" + palette. This uses the online validation feature added in Firebird 2.5. The + services's properties enable inclusion/exclusion of tables and indexes using + regular expressions. See. + https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation + +36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger + option on a database. + +37. TIBCustomService: Assign method implemented to allow copying of service login + context between service API components. "Detach" method now only detaches + service when last reference to the service interface detaches. Tidy up of + code for SetActive and Attach methods including password hiding. + +38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only + and used to determine the auth method and protocol used for the connection. + +39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using + a Create Database Statement generated by IBX. + +40. All IBServices now have an additional published property "PortNo". This may + be set to a non-standard port number when necessary. If zero then the default + port number is used. + +41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard + and not just the mouse. + +42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added. + +43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the + image index and selected image index for each node to be set from a database field. + +44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included + then database schema includes grants to all users. If not present then the + only user grants included are those to User PUBLIC. + +45. TIBTreeView: performance improvement. When expanding include both expanded node + and child nodes in dataset.
