October

• Make better XNET's error messages in firebird.log
• Work on trace services
  • Remove double quotes around value of AuditTraceConfigFile setting, if present
  • Catch AdminException and re-throw known for us Firebird::Exception descendant
  • Report alias (if present) instead of expanded file name at failed attach event
  • No need to report full path of the failed traced plugin module as we load it from only one, well-known location
• SQL statements for user management
  • Pass explicit role to the security database attachment
  • Better error messages - append original error occured in security database after primary error code
• Windows Vista support
• Mark all executables with "asInvoker" execution level. It avoid virtualization in Vista and Windows 7
• Mark instXXX with "requireAdministrator" execution level as its really requires administrative privileges.

• Correct order of searching for ib_util.dll
• Fixed bug CORE-2684 : Error page NNN is of wrong type (expected 7, found N)
• Fixed bug CORE-2720 : Wrong evaluation result with divide and unary plus\minus operations

• Correct order of searching for ib_util.dll
• Backport fix for bug CORE-2684 : Error page NNN is of wrong type (expected 7, found N)
• Backport fix for bug CORE-2720 : Wrong evaluation result with divide and unary plus\minus operations

• Fixed bug CORE-2729 : Current connection may be used by EXECUTE STATEMENT instead of creation of new attachment
• Fixed bug CORE-2731 : Recursive EXECUTE STATEMENT works wrong
• Documentation
  • README.fb_cancel_operation
  • README.services_extension
  • README.trace_services
  • correction of example for trace services


• Fixed bug CORE-2771 : AV at backup of database with GTT
• Improvement CORE-2773 : Let "Start trace session" service report ID of newly created trace session
• Improvement CORE-2774 : Let "Start trace session" service report if no trace plugins were loaded by the engine
• Improve performance a bit.
