Developer's Report: Firebird Core Development
February to April 2014

February

Trunk
  • Use qualified name for packaged stored procedures in trace output
  •  
  • Increased default unload delay time for unused plugin modules from 1 sec to 1 min
  •  
  • Windows only changes:
* try to load DLL's from fbclient's folder if DLL's file name contains no full path
* if attempt above failed, load DLL using given file name (as is)
* cleanup
* use LOAD_WITH_ALTERED_SEARCH_PATH flag unconditionally. It should fix CORE-4275 (create database fault if fbclient.dll loaded from another directory (Providers = Engine12))
 
  • Let subroutine's statement know what procedure\function it belongs to. It allows to know subroutine name   and thus produce better error messages and trace subroutine's correctly.
  • Improvement CORE-4345: Ability to trace stored functions execution
  • Fixed warning by PVS-Studio
  • Fixed Windows build
March

Trunk
  • Refactor TraceParamsImpl and company
  • Additional patch for CORE-3362 : Cursors should ignore changes made by the same statement:

B2_5_Release
  • Fixed bug CORE-4372 : Deadlock is possible when two data pages contains record fragments pointing to each other
  • Fixed bug CORE-2848 : "lock conversion denied" or "lock denied" error
April
 
Trunk
  • Improvement CORE-4252 : Add table name to text of validation contraint error message, to help identify error context
  • Fixed event leak.
B2_5_Release
  • Improvement CORE-4252 : Add table name to text of validation contraint error message, to help identify error context
  • Avoid issues with not initialized members of record_param.
  • Load icuin30.dll from the same folder as already loaded icuuc30.dll. It should fix CORE-3133 : FBEmbed.dll does not load icuin30.dll from same folder as itself (icudt30.dll, icuuc30.dll load OK)
Other

Investigated few issues with nbackup under load and at out-of-disk condition.
