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). |

RELEASE. |

NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE. |

|
1. IBExtract: Identity columns - add additional check for null column for generator name. |
| 110 |
|
|
| 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 and exception. |

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 |
| 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 directory a prescribed data directory (including |
| 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. |
| 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 |
| 267 |
|
service when last reference to the service interface detaches. Tidy up of |
| 268 |
|
code for SetActive and Attach methods including password hiding. |
| 269 |

38. TIBDatabase: new proterties: AuthenticationMethod and RemoteProtocol. Read only |

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 |
