harbour-core/harbour/include/hbrdddbf.h
Przemyslaw Czerpak d4af3b201b 2006-08-23 23:12 UTC+0200 Przemyslaw Czerpak (druzus/at/priv.onet.pl) 
* harbour/include/hbrdddbf.h
  * harbour/source/rdd/dbf1.c
  * harbour/contrib/rdd_ads/ads1.c
    * synced with xHarbour

  * harbour/include/hbapi.h
    + added uiClass and uiMethod to HB_STACK_STATE structure
    - removed puiClsTree from HB_BASEARRAY structure

  * harbour/include/hbvmpub.h
    ! fixed typo in HB_ARRAY_OBJ() declaration

  * harbour/source/vm/arrays.c
    - removed puiClsTree from HB_BASEARRAY structure

  * harbour/source/vm/classes.c
    - removed static variable s_pMethod to make classes code MT safe
    * store information about current method index and supercasting on
      HVM stack in HB_STACK_STATE structure
    ! changed hb_objGetRealClsName() to not use puiClsTree - this functions
      was never working as it should when object was supercasted.
      Now it simply returns name of class where method was defined and
      inherited.
    - removed hb_objPopSuperCast() and changed last parameter in
      hb_objGetMethod() from BOOL * to PHB_STACK_STATE
      hb_objPopSuperCast() is not longer necessary
    - removed hb_mthRequested() and first parameter from hb_mthAddTime()
    + added char * hb_clsName( USHORT uiClass );
    + added TOFIX notes in hb___msgGetData() and hb___msgSetData()

  * harbour/source/vm/estack.c
    + added uiClass and uiMethod to HB_STACK_STATE structure

  * harbour/source/vm/hvm.c
    * updated for above modifications

  * harbour/source/vm/proc.c
    ! do not use hb_objGetRealClsName() anymore but retrieve information
       about _REAL_ class form HVM stack
