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 deLayoutChanged 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). + +19. TIBExtract: Full BigInt value range now supported for Generators/Sequences. + +20. Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their + stubs. Pedantic fix really, as procedures output in dependency order anyway. + +21. TIBExtact: Package Headers and Package Bodies are now included in the extracted + DDL (Firebird 3 and later only). + +22. TIBLookupComboBox Autocomplete Fixes: + i. Only appended text is now selected after autocomplete. + ii. Uppercase keys no longer ignored for autocomplete. + iii. Retain Prefix case is now honoured correctly. + iv. When a DataSource is assigned, typing after autocomplete now extends prefix + before autocomplete performed. i.e. behaviour now the same as when + no DataSource assigned. + +23. Single Line Comments starting with '--' are now ignored when occurring + between SQL statements. + +24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then + ObjectNames are converted to upper case before matching against metadata object + names, unless the objectname is delimited by double quotes, in which case, the + double quotes are removed and the remaining string is used (unmodified) to match + against the metadata object name. + + If true then the ObjectName is used as is without modification and matched + against the metadata object name. No attempt is made to remove double quotes. + +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.

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.

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.

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.
