* harbour/include/hbapi.h
* moved HB_STACK_STATE declaration from hbstack.h to hbapi.h
it's covered by _HB_API_INTERNAL_ macro so it should not
effect 3-rd party code
* modified hb_struSymbol structure:
LONG stackbase
replaced by:
PHB_STACK_STATE stackstate
this modification allows to keepadditional information bound with
function call stack accessible from different HVM modules.
Now it's used by memvars code to keep/update PRIVATE variables
stack pointers. I plan to store in HB_STACK_STATE structure
information additional information for classes code like super
casting or instance variables offsets in new OOP model I'm working on.
It can be also used by debugger code to retrieve some informations
about executed functions without active updating by main HVM loop.
+ added hb_memvarsClear() - cleanly clears all PRIVATE and PUBLIC
variables
+ added hb_memvarUpdatePrivatesBase() - updates PRIVATE stack base
offset so PRIVATE variables created in current function/procedure
will not be removed when it returns
- removed hb_memvarsRelease() and hb_memvarValueNew()
* harbour/include/hbstack.h
+ added hb_stackClearMevarsBase() - helper function for hb_memvarsClear()
clears PRIVATE stack offsets in executed functions
* changed to static offset from int to long - in different places we
were using int or long in HVM so I cleaned the HVM code to always
operate on the same type
* harbour/source/vm/estack.c
* set/restore PRIVATE stack base offset in hb_stackNewFrame()/
hb_stackOldFrame()
* updated for new HB_IT_SYMBOL structure
* harbour/source/vm/hvm.c
! removed setting/restoring PRIVATE stack base offset in hb_vmExecute()
It make code like:
eval(&("{||VAR:=1}"))
Clipper compatible
* updated for new HB_IT_SYMBOL structure
* changed order of execution exit procedures for clean memvars removing
and future destructors execution. I'll describe it better when I'll
add destructors.
* harbour/source/vm/memvars.c
! fixed CLEAR MEMORY - now this function should be safe in Harbour
It's not exactly compatible with Clipper because I intentionally
didn't replicated some Clipper bugs like possible memory corruption.
+ added hb_memvarsClear() - cleanly clears all PRIVATE and PUBLIC
variables
+ added hb_memvarUpdatePrivatesBase() - updates PRIVATE stack base
offset so PRIVATE variables created in current function/procedure
will not be removed when it returns
! fixed releasing PUBLIC and PRIVATE variables which were passed by
reference and are still active on HVM stack or in codeblocks as
detached locals (see: hb_memvarDetachDynSym())
* modified hb_memvarFindSymbol() to be more Clipper compatible
% optimized hb_memvarRelease() to operate or PHB_DYNS instead of
string comparison and not make linear dynamic symbol scan for
PUBLIC or not existing symbols
- removed hb_memvarReleasePublic()

* harbour/source/vm/proc.c
* harbour/source/vm/pvalue.c
* updated for the above modifications
* harbour/source/rtl/memvarbl.prg
* harbour/source/rtl/menuto.prg
* use __mvEXIST( cMemvar ) instead of __mvSCOPE( cMemvar ) > HB_MV_ERROR
__mvEXIST() is much faster function
* harbour/source/rtl/type.c
* execute hb_memvarUpdatePrivatesBase() after macro type checking.
This should not be necessary but we are not Clipper compatible here
and this is work around for difference in our TYPE() implementation.
Clipper for:
? TYPE("VAR:=1")
create PUBLIC variable VAR when [x]Harbour PRIVATE one.
Should we try to make it Clipper compatible?
The above should fix problems reported with memvars. We are not 100%
Clipper compatible but unlike in Clipper we cannot break VM internals
using some operation on references to memvars and detached locals
and/or RELEASE.../ CLEAR MEMORY. This modifications should be intensively
tested. If you will find any problems with current code please inform me.
I'd like to hear your opinions about memvars created by TYPE() (see above).
Should we change it? It may not be very easy operation - we will have to
change macro compiler and add new PCODE for that.

+ added hb_xRefInc(), hb_xRefDec(), hb_xRefFree(), hb_xRefCount(),

and covered by internal API macro. Should not be used by 3-rd
party code because we may change them in the future or even remove.
+ added hb_gcRefInc(), hb_gcRefDec(), hb_gcRefFree(), hb_gcRefCount()
functions. These are also internal function which corresponds to the
above hb_x*() ones.

necessary and it should never be public function - it was implemented
in very dangerous way.
- removed hb_codeblockDelete() function.
- removed hb_memvarValueDecGarbageRef()

of symbol table
