+ added hash items, f.e.:
local h1 := {=>}, h2 := { "a"=>1.234, "b"=>2.345 }
? h2[ "a" ], h2[ "b ]
+ added support for DYNAMIC function declaration - it allow to define
functions which are lately bound at runtime, f.e.:
/*** t01.prg ***/
dynamic func1
proc main()
local h:=__hrbload("t02.hrb")
? func1()
return
/*** t02.prg ***/
func func1
return "Hello!!!"
% use new FUNCALL structure to hold EXTERNAL and DYNAMIC functions,
it reduce memory usage, FUNCALL is much smaller then FUNCTION
% use symbol scope bits when possible instead of making some linear scan
+ added new enumarator message: __ENUMKEY - it allow to access
key value when hash item is base enumerator value, f.e.:
proc main()
local v, h:={"a"=>1.000,"b"=>2.000,"c"=>3.000}
heval( h, { |k,v,i| qout( k, v, i ) } ); ?
for each v in h
? v, "=>", v:__enumKey(), v:__enumValue(), v:__enumIndex(), ;
valtype(v:__enumBase())
v += 0.123
next
? ;heval( h, { |k,v,i| qout( k, v, i ) } )
return
+ added C level hb_hash*() functions
+ added support for full HASH item cloning and updated array cloning
to also clone nested hashes - please note that xHarbour does not do
that, in xHarbour ACLONE() clones _ONLY_ nested arrays and HCLONE()
_DOES_NOT_ clone _ANY_ nested items.
* harbour/include/hbextern.ch
+ added hash functions HB_H*()
* changed INET*() functions to HB_INET*()
+ added hash functions H*() and socket functions INET*() when
HB_COMPAT_XHB is set
* harbour/include/hbtypes.h
+ added missing HB_EXTERN_BEGIN / HB_EXTERN_END
* harbour/include/hbpp.h
* harbour/source/pp/ppcore.c
! added protection against automatic word concatenation in some cases
! fixed preprocessing expressions when match marker matches ';' token
* harbour/source/rtl/Makefile
+ harbour/source/rtl/itemseri.c
+ added functions for item serialization: HB_SERIALIZE() and
HB_DESERIALIZE() - these function are not binary compatible
with xHarbour functions with the same names but make very
similar job with the exception to serialization of codeblock
and object variables - Harbour does not allow to serialize
codeblocks and serialize objects as arrays.
In most cases these functions can replace the xHarbour ones
+ added HB_DESERIALBEGIN() and HB_DESERIALIZE() functions covered
by HB_COMPAT_XHB macro - this functions are only for compatibility
with existing xHarbour code, In Harbour HB_DESERIALBEGIN() is
dummy function which returns first parameter and HB_DESERIALNEXT()
is a simple wrapper to HB_DESERIALIZE() so it's not necessary to
use them.
* harbour/source/rtl/hbinet.c
* changed INET*() functions to HB_INET*() and enable them for default
build
+ added INET*() functions wrappers covered by HB_COMPAT_XHB macro
* harbour/source/rtl/hbrandom.c
+ added HB_RANDOMINT() - xHarbour compatible
* harbour/source/rtl/len.c
+ added support for HASHes
* harbour/source/rtl/valtype.c
+ added support for HASHes
+ added set of HB_IS*() functions - they are a little bit faster then
calling VALTYPE( v ) == <cVal>
- removed HB_ISBYREF() - this function cannot longer work, it was using
a Clipper incompatible anomalies in passing variables by reference I
fixed so it has to stop to work. If it will be realy necessary to
implement HB_ISBYREF() function then please inform me - it will have
to be done at compiler level or with some much deeper HVM stack
checking.
* harbour/source/vm/extend.c
! fixed hb_extIsArray() and hb_extIsObject() to work well with
parameters passed by reference.
Please note that now hb_extIsArray() return TRUE only for pure arrays
not object values.

Please test - a lot of above code is not well tested, also some peaces
were written over year ago for different things (f.e. serialization for
NETRDD) and now I collected them and committed.
The TIP library was not tested at all. It can be compiled but I cannot
say if it works - I hope that people familiar with it can make necessary
test and fixes.
It's also not the final version of low level HASH item code. I'm working
on more efficient structure which uses binary tries but I cannot say when
I'll finish it (maybe in this weekend or maybe in next year) so I committed
working version now even if I'm not happy with overall performance (BTW
not worser then in xHarbour)

optimizer
* chaned a little bit WITHOBJECT syntax.
Now WITHOBJECT somefunc(); END is not silently ignored and call
to somefunc() is left. This optimization also works when there
are empty line between WITHOBJECT and END

! added protection against cyclic references in arrays
* eliminated action parameter from hb_vmRequestReenter() /
hb_vmRequestRestore()
* moved s_lRecoverBase and s_uiActionRequest to HB_STACK structure
for future MT HVM version
+ added internal item structure hb_struRecover - it's not real item
but this structure is used to keep information about BEGIN SEQUENCE
data - it reduce HB_STACK usage
+ added support for ALWAYS clause in BEGIN SEQUENCE
The syntax is:
BEGIN SEQUENCE
<code>
[ RECOVER [ USING oErr ] ]
<recoverCode>
[ ALWAYS ]
<alwaysCode>
END [ SEQUENCE ]
It's guaranteed that <alwaysCode> is _ALWAYS_ executed even if
inside <code> or <recoverCode> some new exceptions like RETURN,
BREAK or QUIT will appear.
Please note that when the following code is executed:
BEGIN SEQUENCE
<code>
ALWAYS
<alwaysCode>
END
(without RECOVER clause) then BREAK exception inside <code> is not
recovered, <alwaysCode> is executed and then BREAK exception is
passed to outer BEGIN SEQUENCE. This is the same semantic as
used in TRY / [ CATCH ] / FINALLY / END
Those of you who prefer to use TRY / CATCH / FINALLY / END instead
of BEGIN SEQUENCE / RECOVER / ALWAYS / END can simply add to your
source code:
#command TRY => BEGIN SEQUENCE
#command CATCH [ oErr ] => RECOVER [ USING <oErr> ]
and:
errorBlock( {|oErr| break( oErr ) } )
Though instead of 'break( oErr )' I suggest to use some small function
which will support some basic recovery/substitute operations like in
default errorsys() and LockErrHandler() to not break existing code
which may depends on the default behavior.
If you want I can add direct support for TRY / CATCH / FINALLY / END
but I'm not sure it's really necessary.
Please note also that in Harbour ALWAYS code is execute even for QUIT
excpetion.
When <alwaysCode> is executed current exception is stored and restored
when is finished. If new exception appears inside <alwaysCode> then
restored exception depends on the priority in the following order:
QUIT // highest priority
BREAK
RETURN
If both exceptions have the same priority and contain additional value
(error object in BREAK or return value in RETURN) then the recently set
one is restored. It's similar behavior to destructor code.
* harbour/source/common/hbstr.c

to use it also in compiler and preprocessor
* harbour/source/compiler/ppcomp.c
* harbour/source/pp/ppcore.c
* harbour/source/pp/pplib.c
* tuned error messages to be more Clipper compatible
% use static strings from hb_szAscii
* harbour/source/rtl/alert.prg
* use hb_gtInfo( GTI_FULLSCREEN ) to detect type of GT driver
! some minor fixes
TOFIX: we have to also use GTI_ISCTWIN or add window allocation
to standard GT drivers to be Clipper compatible when CTWIN
is used - In Clipper Tools ALERT() works in differ way then
the standard one. It creates separate window box to display
data, supports SETKEY(), etc. I'll think about adding some
extended support for ALERT() and similar operations (f.e.
separate debugger windows) to GT API so it will be also
possible to overload standard alert() command by GUI message
box in GTGUI and similar GT drivers.
* harbour/source/rtl/binnumx.c

* harbour/source/vm/hvm.c
! fixed Harbour support for accessing string characters with array
index operators []
+ added support for #define HB_COMPAT_XHB - it's disabled by default.
When set it enables some of xHarbour features like negative array
indexes calculated from tail, accessing string characters with []
operators (warning it's not compatible with default Harbour version
enabled by -ks during compilation and //flags:s at runtime - in
xHarbour compatibility mode "ABC"[2] returns "B" when in Harbour 66)
and some other minor features.
* harbour/source/compiler/cmdcheck.c
* added support for optional setting C output type in -go switch
Now it accepts optional digit [0123] after -go in the same way
as -gc, f.e.: -go3
* harbour/source/compiler/harbour.c
* call hb_compExprLstDealloc() only when errors appeared during
compilation - it disable automatic freeing all allocated expressions
in clean compilation. I make it intentionally for easier detecting
problems one some expressions are not freed. So far the final cleanup
code always deallocated expressions what can hide some real bugs.
* harbour/source/vm/hvm.c
! fixed very serious bug in HVM closing. The s_uiActionRequest flag
was not cleared before hb_rddShutDown() so when RDD buffers were
hot and flushing required some PCODE evaluation (f.e. index KEY
or FOR expression) then they were not properly evaluated.
* harbour/source/vm/macro.c
* minor improvement
* harbour/utils/hbtest/rt_misc.prg
! fixed one of expected result, it was neither Harbour nor Clipper
result (I've just made some test with Clipper), I do not know why
it existed

* harbour/include/hbapiitm.h
* harbour/source/vm/itemapi.c
+ added hb_itemCopyToRef(), hb_itemMoveToRef(), hb_itemMoveRef(),
hb_itemUnRefWrite()
* harbour/include/hbexprb.c
! use HB_P_DUPLUNREF instead of HB_P_DUPLICATE when assign is used in
push context - Clipper compatible behavior, see:
x:=10
f(y:=iif(.t.,@x,))
? x, y
func f(x)
x+=100
return nil
* harbour/include/hbver.h
* harbour/source/common/hbver.c
* changed status to "devel"
* harbour/source/common/expropt2.c
* disabled setting NIL when iif(.t.,,sth()) is optimized to avoid
warning when iif() is used as statement - to fix number of parameters
passed to function in code like f(iif(.t.,,sth())) we will need a
little bit deeper modification
* harbour/source/compiler/complex.c
* added hack for potential problems caused by WITH OBJECT syntax, f.e.
in code like:
proc p(obj,x)
case:=myCaseClass():new()
retu:=myCaseClass():new()
WITH OBJECT obj
do case
case x==nil
case:value()
case:action()
retu:sth()
end
END
case:action()
retu:sth()
return
case:action(), case:value(), retu:sth() can means two different things
and compiler cannot guess which one should use. It cannot be fixed
because it's caused by bad WITH OBJECT syntax. In xHarbour constractions
like case:value() or retu:sth() are always used as in WITH OBJECT
context what is not Clipper compatible. I do not want to introduce
such limitations. We have two choices: change WITH OBJECT syntax or
add some hack to "hide" the problem a little bit. Now I intorduce
ugly hack which check number of spaces between ':' so
case :action()
is compiled as case condition using WITH OBJECT message and
case:action() as sending message to object in case variable
* harbour/source/compiler/harbour.y
* harbour/source/compiler/harbour.yyc

s:="abcdefghijklmnopqrst"
for each c in @s
if c$"aeio"
c:="*"
endif
next
? s // "*bcd*fgh*jklmn*pqrst"

* accept ... in codeblocks only when codeblocks parameters are defined
as variables, f.e: {|a,b,...|qout(a+b,...)}
! fixed error in a[&s]:=100
+ added support for a[...] - now ... can be used in the same context as

* forbid creating function pointer when function is used with parameters,
f.e.: x:=@f1(1,2,3)

I think that we should replace this library with hbodbc from xHarbour.
* harbour/contrib/ole/ole2.c
* updated for XCC
* harbour/include/hbdefs.h
* include stdint.h if available
* harbour/source/compiler/complex.c
! fixed yet another stupid mistake in WITHOBJECT token

* harbour/include/hbexprb.c
* harbour/include/hbexprc.c

! fixed GPF during compilation of @:var, @:&var, @o:&var
+ added support for @o:&var and @:var, @:&var inside WITH OBJECT
statement
* changed PCODE generated of ++,--,+=,-=,...
Now left side expression is evaluated _ONLY_ once and when object
messages are used it's guarantied that exactly the same object
variable will be used. It also fixes some problems which exists
in Clipper. This optimization is enabled by -kh flag (by default)
and can be disabled with -kc.
% optimize ald macros in ++,--,+=,-=,... operations
* add automatically "_" prefix when macro message is used in assignment
context, f.e.:
s:="osCode"
o:=errorNew()
? o:&s
o:&s := 100
? ++o:&s
? o:&s *= 5
* harbour/include/hblang.ch
- removed #xtranslate - this file is included by C code and some C
compiler do not like unknown directives
* harbour/utils/hbtest/rt_math.prg

* general PCODE cleanup and address most of TODO/TOFIX notes in
source code:
! fixed GPF traps when too long string or codeblock is generatd
+ added support for 16MB codeblocks and strings
! removed macrocompiler limitation for jumps range
! fixed GPF when more then 255 local variables is used and added
support for 2^15 locals
! removed all strtok() functions
% added optimization for all +=, -=, *=, %=, ^=, **= operations
when left side of expression is variable or array item
% added optimization for all +=, -=, *=, %=, ^=, **= operations
when left side of expression is object method and updated ++, --
for new code. It's still disabled until we will not add support
for late evaluated reference items to HVM
! fixed a[++i]++ and similar operations (a[++i]*=2, ...). Now ++i is
executed only once. It's not Clipper compatible but it was in
TODO note in source code. It can be disabled by -kc option
* finished support to xHarbour like #pragma TEXTHIDDEN(1)
! fixed local add int optimization when PARAMETERS used after
optimization changed local variable number over 255
! fixed GPF trap when in HB_P_<op>EQ PCODEs when executed for
direct values
* others
! fixed problems reported by Chen
* optimized strtran(), left(), right() to not create new string copy
when the same value is returned
* harbour/include/hbstack.h
! fixed typo in function name, should be: hb_stackLocalVariable()
not hb_stacklocalVariable()
+ added hb_stackId()
* hide hb_stack declaration when HB_STACK_MACROS is not set
* harbour/source/vm/dynlibhb.c
* use hb_stackId()
* harbour/source/vm/estack.c

* general code cleanup: all strcpy() and strcat() replaced hb strn*()
and hb_strn*(), sprintf() by snprintf(), etc.
It fixed some possible buffer overflow but it's also possible that
it will exploit some some hidden so far problems but I strongly
prefer to know about them ASAP to fix them before final 1.0 release.
! fixed bug I introduce in codeblock falgs which disabled early macro
evaluation in codeblocks.
! added missing protection against execution by bison destructor for
used CBSTART token on syntax error.
% use PP stringify logik added for FLEX support to remove all redundant
spaces in stringified for early macro evaluation codeblocks and add
spaces between operators if after preprocessing they were removed.
Now we are supporting also some code which cannot be compiled by
Clipper.
% cleaned and improved the speed of printer redirecting in console code.
Chen please check if CG still reports problems and if not ubdate
TODO/TOFIX or inform me about them.
* some cleanups in building process for different *nixes: MacOSX, SunOS,
*BSD, etc.
* removed not longer necessary (I hope) compiler flag to force default
'char' type as signed. Now Harbour should work with signed and unsigned
char without any problems. To other developers: please remember that
when you are using 'char' as 8 bytes signed integer then it's a bug.
Always explicitly use: 'signed char' in such case. On some platforms
it's not possible to set default type for 'char' so if you hardcode
that 'char' is signed or unsigned somewhere then code will not be
portable. Chen if you will find a while to also rebuild Harbour with
BCC and -K switch to make some tests with CG then I'll be thankful.
* harbour/include/hbclass.ch
+ added validation for class data names. As additional preprocessor
rule to not use <!marker!>
* harbour/include/hboo.ch
* harbour/source/rtl/tclass.prg
* harbour/source/vm/classes.c
+ added delegate messages
* harbour/include/hbstack.h
* harbour/source/vm/arrays.c
* harbour/source/vm/estack.c
* harbour/source/vm/hvm.c
* harbour/source/vm/proc.c
+ added startup symbol to hb_stack. It gives very good stop
condition for all procedures which trace stack calls and
resolves the problem with hb_stack.pBase which was never
pointing to valid function/procedure symbol when no symbol
was put on HVM stack. Now after hb_stackInit() the first
item is allocated for "hb_stackInit()" symbol so hb_stack.pBase
is always a pointer to valid function/procedure symbol.
* changed the guard condition for buggy code in hb_stackPop()
and similar code from:
hb_stack.pPos < hb_stack.pItems
to:
hb_stack.pPos <= hb_stack.pBase
The old condition was generating usable error message only in the
startup function. In deeply called functions it was only waste of
CPU time on one of the most often call functions. Before it was
activated internal stack structures were corrupted.
If we were leaving for many years without really working stack
underflow protection then maybe we should think about disabling
it at when HB_STACK_MACROS are used and keep it only in real
stack functions for HVM developers. Single protection in
hb_stackOldFrame() I've just added is enough for basic C code
validation.
I created the second version of stack macros without it in
hbstack.h but I would like to hear other developers opinion.
* harbour/include/hbexprc.c
* translate HB_P_INC / HB_P_DEC in (pre|post)(inc|dec)rementation
to HB_P_[PLUS|MINUS]EQ
* harbour/source/vm/hvm.c
- removed not necessary now hb_itemUnRef() in hb_vmInc()/hb_vmDec()
* harbour/source/vm/classes.c
* allow to access object variables using assign messages without
parameter. I do not want to add symmetric behavior for access messages
though it's technically possible but such things should be controlled
by programmer because access messages can have less restricted scoping
then assign ones (READONLY) so I'll add new rule for it in hbclass.ch
* harbour/source/vm/hvm.c
* fixed warning message when object variable reference is
generated using macro compiler without '_' as prefix.
eg:
o:&send()
o:&send.end()
o:&(expr)()
o:&var++
o:&var := 0
o:&(expr)++
WITH OBJECT obj
++:&var
:&var += :&(var2+"oo")
END
NOTICE:
For simple assigments (=,:=), compound assignments (+=,-=,*=,/=)
and for pre/post increment operators( ++,--) the macro should
evaluate to a symbol that starts with underscore '_'.
To access a variable the macro should evaluate to a symbol
with no '_' char.
* harbour/include/common.ch
- removed ISSYMBOL()
* harbour/source/rtl/tclass.prg
* use valtype() instead of IS*()
* some minor modifications
* harbour/source/vm/hvm.c
* minor modification
* harbour/make_rpm.sh
* check for rpmbuild also when BUGGY_RPM is set
* harbour/make_tgz.sh
* removed rebuild hbpptest with shared libraries
* harbour/include/hbapicls.h
+ added definitions for hb_clsCreate(), hb_clsAdd(), hb_clsAssociate()
* harbour/include/hbapierr.h
* harbour/source/rtl/errorapi.c
+ added hb_errFuncName - pseudo function name which can be used as
operation description in new error object. It should help to simplify
some code and fix function names when RT error is generated from C
function which can be executed from different .prg functions.
* harbour/include/hbclass.ch
+ added some missing Classy(y) compatible object variable type
descriptions: Int, Integer, Block
* harbour/source/rdd/dbfcdx/dbfcdx1.c
! disabled early retrieving from the cache key position and key count
* harbour/include/hbvm.h
* harbour/source/vm/hvm.c
+ added: void hb_vmPushEvalSym( void ) for the code which do not
want to access any [P]HB_SYMB structures
* changed symbol name in hb_symEval from __EVAL to EVAL and modified
hb_symEval registration method to not register hb_vmDoBlock as global
function. Having PHB_DYNS address for "EVAL" in hb_symEval.pDynSym
allows to eliminate some strcmp() when we are looking for EVAL public
symbol.
! fixed symbol table updating in PCODE functions for future multi module
.hrb files
* harbour/source/vm/proc.c
* use hb_symEval.pDynSym instead of strcmp()
* harbour/source/vm/arrays.c
* harbour/source/vm/debug.c
* minor code cleanup
* harbour/source/rtl/tclass.prg
* harbour/source/vm/classes.c
% separate message hash table from methods table - it will cause farther
reduction of allocated memory - many thanks to all people who send
me statistics about number of used classes and symbols from their code.
% use hb_symEval.pDynSym
+ added support for object variable type scope checking like in Class(y).
! fixed typo in pushing object class variables by reference
% s_pClasses is now indexed directly by class handle
% some other optimiztions
! make hidden and non virtual invisible in child classes if it overloaded
some other non hidden method. In such case the overloaded method is used
and can be accessed.
! make friend functions real method class oriented not (super)object for
hidden messages
* harbour/include/hbclass.ch
* harbour/include/hbvm.h
* harbour/source/rtl/tclass.prg
* harbour/source/vm/classes.c
* harbour/source/vm/hvm.c
! fixed bug in real codeblock scoping which was exploited by
dictionary resizing
* changed ACCESS messages to ASSIGN ones when object item
reference is created for proper READONLY scope checking.
The reference to object variable can be created only when
caller has sufficient ASSIGN privileges.
+ added FRIEND CLASS and FRIEND FUNCTION support.
It's enough to add class definition:
FRIEND CLASS <classFunc1> [, <classFuncN> ]
and/or:
FRIEND FUNCTION <FuncName1> [, <FuncNameN> ]
and all methods of given class or given function will be able
to access private variables.
Warning!!! Friends cannot access overloaded non virtual methods.
This feature is available _ONLY_ for real class members.
+ added MODULE FRIENDLY to class definition. It causes that all other
functions and classes defined in the same .prg module will have
friend privileges. In such way works xHarbour and there is now way
to disable this "feature" what is IMHO bug. In Harbour programmer
has to explicitly enable it (until he will not change / add new
preprocessor rule and set it as default ;-)). Syntax:
CREATE CLASS .... MODULE FRIENDLY
...
END CLASS
* harbour/source/vm/proc.c
* harbour/source/vm/runner.c
* updated function symbols processing
* harbour/source/compiler/harbour.c
* added note in hb_compOptimizeFrames() about exceeding maximum number
of local variables (255). We should add new pcode(s) HB_P_LARGE[V]FRAME
or generate compile time error.
* harbour/source/vm/macro.c
% minor optimizations
* harbour/contrib/rdd_ads/ads1.c
! fixed casting for C++ compilation

* harbour/source/vm/hvm.c
* harbour/source/vm/itemapi.c

* moved current line number information from hb_struSymbol
to current stack state to keep 16 bytes size for HB_ITEM
on 32bit systems with 4 bytes alignment
* include/hbpcode.h
+ added new pcode HB_P_VFRAME
* include/hbapi.h
+ added USHORT paramdeclcnt to asSymbol structure

+ added support for variable number of parameters in
functions/procedures
+ tests/varparam.prg
* example usage of new syntax for variable number of
parameters
* source/vm/arrayshb.c
* changed HB_APARAMS() to use current stack frame if no
arguments are passed ( HB_APARAMS() == HB_APARAMS(0) )
SYNTAX for variable number of parameters
1) [FUNCTION|PROCEDURE] name( ... )
or
2) [FUNCTION|PROCEDURE] name( var1, var2, varN, ... )
To access passed parameters use the following:
PCOUNT() - returns number of passed parameters
HB_PVALUE( iParamNum ) - returns <iParamNum> parameter
HB_APARAMS() - returns array with all passed parameters
or usual name of parameter variable in case of syntax 2)
* harbour/include/hbexprb.c
* harbour/source/vm/hvm.c
+ added support to compiler for sending messages with multi
parameters resolved by macro operator: s:="1,2,3"; o:msg(&s)
It works just like for functions and it also needs XBASE extension
support enabled during compilation, -kx switch in compiler, it's
enabled by default.
* harbour/source/rdd/usrrdd/usrrdd.c
! added missing DBOI_* index in parameters passed to user ORDINFO()
method.

* harbour/source/vm/classes.c
* harbour/source/vm/codebloc.c
* harbour/source/vm/hvm.c
* harbour/source/vm/itemapi.c
+ added three new PCODEs:
HB_P_MACROSEND - to use for: s:=1,2,3"; o:=send(&s)
HB_P_PUSHOVARREF - to create references to object variables: @o:var
HB_P_ARRAYPUSHREF - to create references to array items, it can be used
in some optimization, f.e.: a[ <exp1> ] += <exp2>
or directly by: func( @a[ <exp> ] )
if we add passing array elements by reference
Implemented in HVM and PCODE generation, the compiler has to be
modified yet to use them.
* changed last parameter in hb_codeblockGetRef() - I'd like to have
all variables in hb_struRefer structure in one place: hb_itemUnRefOnce()
for easier modifications in the future.
* replaced in hb_struRefer 'itemsbase' with 'array'.
+ added hb_arrayGetItemRef() to create references to array elements.
Such reference updates array reference counters.
* changed STATICs passed by reference to use new array item references.
! block destructor execution after classy releasing on HVM exit
* xharbour/include/hbvm.h
* xharbour/source/vm/hvm.c
+ added hb_vmPushDynSym( PHB_DYNS )
It should allow most applications to not use [P]HB_SYMB at all.
Removing PHB_SYMB from 3-rd party .c code may allow us to add
freeing unused symbol tables from HVM in the future.
* harbour/source/vm/classes.c
* temporary restored hb_objGetpMethod()
+ added __ClsCntClasses()
! allocated real methods for OnError and Destructor to keep
the same behavior in these methods as in any others, f.e.
scoping checking or debugging.
* harbour/common.mak
* harbour/utils/hbtest/Makefile
* harbour/utils/hbtest/hbtest.prg
+ harbour/utils/hbtest/rt_class.prg
+ added tests for our classy code. Now destructors and instance
area allocating/casting. Some other in the future.
* harbour/contrib/rdd_ads/ads1.c
* synced with recent Brian fixes in xHarbour
* harbour/include/hbapi.h
+ added 'method' member to hb_struBlock structure
* harbour/source/vm/hvm.c
* initialize 'method' member in hb_struBlock structure
* harbour/source/vm/proc.c
* changed the name of last parameter of hb_procname() from
bSkipBlock to fMethodName and modified to use information
about the class of executed codeblock from new hb_struBlock
members
* harbour/source/vm/classes.c
* removed hb_objGetpMethod() - I hope it's not longer used
* added real codeblock scoping.
In Clipper there is no information where the codeblock where
created and what priviladges/scopes it should has.
Class(y) to resovle this problem when codeblock is executed scans
the HVM stack for the nearest method call and takes scopes defined
for this method. It's a workaround which allow to break standard
access rights though seems reasonable when it's not possible to
store information where the block is created. I've added to block
item structure information about class and method where code block
was created so we can use the exact method priviladges.
Now Harbour classy code can work exactly like Class(y) when compiled
with -DHB_CLASSY_BLOCK_SCOPE and with real code block scoping when
compiled with -DHB_REAL_BLOCK_SCOPE. I set the second (real code
block scopes) as default. If you think we should be strict Class(y)
compatible here then please inform me and I'll change default setting.
+ tests/clsscope.prg
+ added demonstration/test code for class method scoping
* harbour/include/hbvm.h
* harbour/source/vm/classes.c
* harbour/source/vm/hvm.c
+ added hb_vmRequestReenter() and hb_vmRequestRestore()
+ added executing destructors when some exception is active
I forgot about it in previous commit.
+ harbour/tests/destruct.prg
+ added example/test code for object destructors

have to be updated
* harbour/include/hbapi.h
+ added hb_gcRefCheck() and cover some hb_gc* functions by
_HB_API_INTERNAL_ macro
* harbour/source/vm/itemapi.c

* harbour/include/hbclass.ch
* harbour/include/hboo.ch
* harbour/source/rtl/tclass.prg
* harbour/source/vm/arrays.c
* harbour/source/vm/classes.c
+ added support for object destructors
* harbour/source/vm/garbage.c
+ added support for object destructors
+ added logic to detect buggu .prg code which uses destructors
see doc/destruct.txt for more info.
It's also possible that this code will exploit some bugs
in other code which uses GC allocated memory blocks.
* harbour/include/hbvm.h
* harbour/source/vm/hvm.c
* harbour/source/vm/itemapi.c
+ added __enumStop() message for "FOR EACH" overloading
It's guarantied that it will be sent to base item if it is an
object with such message when FOR EACH ... NEXT will finish its job
even if it will be interrupted by EXIT or RETURN to allow base object
clear resources allocated for FOR EACH enumerator. The BREAK exception
is not supported now. This is sth what I'd like to discuss soon when
I'll add destructors. Please think now if we should allow to execute
destructors and other cleanup user code when we are returning to
nearest expection trap (BEGIN SEQUENCE / [ RECOVER /] END) cleaning
the HVM stack.
* harbour/source/vm/classes.c
* keep class shared data in separate array
+ added __CLS_CNTSHRDATA( hClass ) -> nSharedDatas
% some minor optimizations
* harbour/tests/clsscast.prg
+ added test code for shared class data allocating and casting
* harbour/include/hbapicls.h
* harbour/source/vm/hvm.c
* harbour/source/vm/itemapi.c
+ added support for FOR EACH overloading - it's work in progress
do not create any code which may use current solution - it may
change in the nearest future
* harbour/include/hbapi.h
* harbour/source/vm/hvm.c
* harbour/source/vm/codebloc.c
* harbour/source/vm/arrays.c
* moved static base offset from hb_struBlock structure
to HB_CODEBLOCK structure
+ added hclass member to hb_struBlock - it will be used in
the future for checking codeblock scope in classy so we will
real scope checking also for messages sent from codeblocks.
- removed supercast and superoffset members from hb_struArray
structure.
* harbour/include/hbclass.ch
* added class(y) like
@:<MessageName>([<MsgParams,...>])
send operator. It's not exactly the same as in class(y) where
this operator is hardcoded to executing function directly,
needs method name instead of message name and is linked statically.
In Harbour this operator uses message name so can be used also for
instance variables and make dynamic casting to the class from which
current method is inherited. In short words sending messages to @:
instead of :: causes that they work like non-virtual messages in
C++ mode.
If you do not use the same method body in different classes
then you can also use explicitly self casting:
::<myclass>:<msgname>[(...)]
and it will be a little bit faster
* harbour/include/hboo.ch
+ added: HB_OO_MSG_ASSIGN, HB_OO_MSG_ACCESS,
HB_OO_MSG_CLSASSIGN, HB_OO_MSG_CLSACCESS
They should be used insted of HB_OO_MSG_DATA and HB_OO_MSG_CLSDATA
This resolves problems with name conflicts when we were detecting
type of message (ACCESS/ASSIGN) by checking the first character
in message name. F.e. now it's possible to create exported instance
variable called __WithObject and it will be used in all WITH OBJECT
statement instead of the base object value. It's simple and effective
WITH OBJECT overloading.
I kept backward compatibility for HB_OO_MSG_DATA and HB_OO_MSG_CLSDATA
but I strongly suggest to update code to use new constants.
+ added HB_OO_MSG_REALCLASS
* harbour/source/rtl/objfunc.prg
* harbour/source/rtl/tobject.prg
* harbour/source/rtl/tclass.prg
* use HB_OO_MSG_[CLS]{ASSIGN,ACCESS} instead of HB_OO_MSG_[CLS]DATA
* harbour/source/rtl/tclass.prg
+ added REALCLASS message to creted classes - it's used for @: operator
* harbour/source/vm/classes.c
* updated for above modifications
* calculate instance area offset in supercasting dynamically - it
will allow to eliminate multiple instance area allocating when
in the inheritance tree the same class exists more then once and
also quite easy add support for non-virtual messages.
! fixed GPF in __CLSINSTSUPER() class function generate HVM exception
% do not inherit unaccessible inline blocks
* some other minor optimization, fixes and code cleanups
* harbour/source/rdd/usrrdd/usrrdd.c
! fixed HB_TRACE message
* harbour/source/rtl/errorapi.c
! generate internal error if ErrorNew() function does not return an object
* harbour/source/vm/itemapi.c
* modified hb_itemClear() to be reentrant safe - the new version
can be also better optimized by C compiler so should be also faster
* harbour/source/rdd/dbcmd.c
! initialize lpdbOrdCondInfo in DBORDERINFO structure before
passing to ORDCREATE()
* harbour/source/vm/fm.c
! fixed typo in memset() when HB_PARANOID_MEM_CHECK enabled
* harbour/source/vm/hvm.c
! fixed item type used for iterator
* harbour/TODO
+ added simpler example for memory leak in macro compiler:
? type("user input")
* harbour/source/macro/macro.y
* replaced TABs with SPACEs
* harbour/source/vm/classes.c
* added some TRACE() messages
+ added support for executing functions with <symItem>:EXEC()
registered dynamically after creating <symItem>
* harbour/source/vm/hvm.c
* minor modification
* harbour/include/hbexprc.c
! fixed bug in wrong integer negating, f.e.:
proc main(); local i:=0; i-=-32768; ? i; return
! fixed PCODE generated for +=, -=, /=, *= expressions when right side
of expression is undefined variable - it's possible that it will be
field and we will have RT error. It fixes tt4.prg example form TODO
file.
* harbour/TODO
- removed tt4.prg example from TOFIX
* harbour/source/vm/classes.c
! fixed supercast message validation
* harbour/source/vm/hvm.c
! fixed very bad typo in hb_vmMinus() which can cause wrong
results when on 64-bit integer overflow
* harbour/ChangeLog
+ harbour/ChangeLog.016
! added ChangeLog.016 and updated number - mistake in my previous commit
* harbour/source/vm/classes.c
* stronger parameters validation and fixed some possible problems
in hb_objGetMethod()
+ added support for assigning enumerator value by:
<enum>:__enumValue(<newVal>)
and enumerator index by:
<enum>:__enumIndex(<newIndex>)
It's a work in progress - please do not create any code which may
need such functionality yet
* harbour/source/vm/debug.c
* harbour/source/vm/hvm.c
* minor code cleanup
+ harbour/source/codepage/uckam.c
+ added missing in my previous commit file
* harbour/include/hbvmpub.h
* harbour/source/vm/dynsym.c
+ added USHORT uiSymNum to HB_DYNS structure - I will need it for MT
as index for thread local HB_DYNSYM values for MT version in the
future but now I use it as perfectly efficient continuous hash
value for all symbols. Of course PHB_DYNS address is also perfectly
good hash value and in classes code can be used but it does not
guaranties that all messages will cover well whole 16bit area used
as message pool without dynamic bucket size modification.
* harbour/source/vm/classes.c
* changed hashing method. Now it uses really unique base hash key
values which can cover whole 16 bit area so mathematically it's
not be possible to break it by any combination of method names
as long as our dynamic symbol table will be limited to 2^16 symbols.
It still consumes more memory then necessary and I'll change it in
the future but it's much less then before.
The BUCKET size is smaller (4) and all calculations are done only
with bit shifts so it should be also faster.
* use ULONG instead of USHORT to calculate maximum number of methods
to avoid possible overflow problems if it reach 2^16 (rather
impossible in normal application - it will have to create more then
2^15 symbols)
! some other fixes and code cleanup
* harbour/source/vm/hvm.c
* minor modifications
* 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
* 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/include/hbvmpub.h
* harbour/include/hbxvm.h
* harbour/source/compiler/gencc.c
* harbour/source/vm/classes.c
* harbour/source/vm/debug.c
* harbour/source/vm/itemapi.c
* harbour/source/vm/pcount.c
* 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.

parameters, etc.
We still have some public functions which are not used by core code
and not declared in header files, like:
hb_memvarValueBaseAddress(), hb_memvarGetVarHandle(),
hb_memvarGetValueByHandle(), hb_clsCreate(), hb_clsAdd(),
hb_clsAssociate(), hb_hashTableDel(), hb_hashTableSize(),
I haven't touched them yet though we will have to keep in mind that
we should make sth with them.
* harbour/include/hbstack.h
* harbour/source/vm/estack.c
+ added:
int hb_stackCallDepth( void )
LONG hb_stackBaseProcOffset( int iLevel )
* harbour/source/vm/arrays.c
* harbour/source/vm/proc.c
* use hb_stackBaseProcOffset()
* harbour/source/vm/hvm.c
- removed s_ulProcLevel used by HB_DBG_PROCLEVEL() - count the call
stack dynamically using stack data - a little bit slower but it's
not widely used function, now is MT safe and we eliminated some
small overhead in each function call so statistically we improved
overall performance
* harbour/include/hbapifs.h
* changed order of members in HB_FNAME structure to avoid possible
problems with alignment
* harbour/include/hbexprb.c

* harbour/source/rtl/filesys.c
* harbour/source/rtl/fstemp.c
* code formatting and casting

* use HB_MACRO2STRING() macro for default lang setting
* harbour/include/hbrdddel.h
* harbour/source/rdd/delim1.c
* harbour/source/rdd/dbcmd.c
+ extended COPY TO ... DELIMITED ... / APPEND FROM ... DELIMITED ...
to support some other common formats.
COPY TO ... DELIMITED WITH TAB
APPEND FROM ... DELIMITED WITH TAB
uses chr(9) as field separator and without string delimiters
COPY TO ... DELIMITED WITH PIPE
APPEND FROM ... DELIMITED WITH PIPE
uses '|' as field separator and without string delimiters
COPY TO ... DELIMITED WITH ( { cStrDelim, cFldSeparator } )
APPEND FROM ... DELIMITED WITH ( { cStrDelim, cFldSeparator } )
allows users to set and any character field delimiters and fields
separators
* harbour/source/rtl/set.c
! fixed possible GPF after hb_setListenerRemove()

a := { &v }
f( &v )
Now all data is stored on HV * stack without any external registers
which have to be saved/restored or updated in chosen operation.
This modification was necessary to make HV * reentrant safe and it
also eliminated some small overhead caused by old code.
I hope I haven't break anything in compiler - Ryszard please fix me
if I made sth wrong.
* harbour/source/vm/hvm.c
* harbour/source/compiler/harbour.y

PCODE table has been updated and all .prg code which used modified PCODEs
has to be recompiled
