* contrib/rdd_ads/adsfunc.c
! Fixed warning in ADSDIRECTORY() for ADS >= 9.00.
* contrib/rdd_ads/adsfunc.c
* contrib/rdd_ads/adsmgmnt.c
+ Added AdsIsEmpty( <cFieldName | nFieldPos> ) -> <lValue>
With .adt tables will return .T. if value of the field is NULL.
With .dbf it's just equivalent to Empty().
(by Luis Krause Mantilla)
+ Added ADSMGGetOpenTables( nMaxNumberOfFilesToReturn, cUserName, nConnection )
+ Added ADSMGGetOpenIndexes( nMaxNumberOfFilesToReturn, cTableName, cUserName, nConnection )
(by Antonio Carlos Pantaglione & Brian Hays)
; Changes borrowed from xhb, added minor optimization, formatting and warning fix.
* include/hbclass.ch
! Comment typos.
* source/rtl/tget.prg
! Fixed to not extend ::left(), ::right(), ::backspace(),
::delete() with an internally used (but also externally
accessible) extra parameter. This is interface is now
made fully C5x compatible.
* tests/rto_tb.prg
! Fixed to override __eInstVar53() (instead of _eInstVar())
* include/hbextern.ch
* common.mak
* source/rdd/Makefile
+ source/rdd/dbcmdhb.c
+ Added non-internal versions of __dbPack() and __dbZap(),
named: hb_dbPack() and hb_dbZap(). If group needs it I
can add dbPack() and dbZap() too in separate files to
lessen the problem of name collision with app code.
* source/rtl/inkey.c
* Formatting.
+ HB_KEYPUT(): Now possible to pass an array with string elements.
(see feature in xhb/__KEYBOARD())
* HB_KEYPUT(): For string parameter it now uses hb_inkeySetText()
API, rather than a loop of hb_inkeyPut()s.
* contrib/xhb/xhbfunc.c
! xhb flavour of __KEYBOARD() sync fixed. (hb_inkeySetText() got
extended in xhb, so here we're using hb_inkeyPut() for single
numeric key codes).
; Now same code is used as in HB_KEYPUT().
* source/vm/memvars.c
* source/vm/hvm.c
* source/vm/arrayshb.c
+ Added HB_C52_STRICT branches for the remaining RTEs
which produced different results in hbtest.
! Fixed HB_C52_STRICT RTE for AFill().
; NOTE: It's not possible to build Harbour currently when
HB_C52_STRICT, so it's not easy to test these.
* include/hbclass.ch
! Typos.

! fixed -w3 warnings when class name is different then function name
* allow to overwrite predefined classes definitions
it's a dirty hack but current implementation of predefined
function and class declarations has to be rewritten from scratch
in the future so I make it intentionally - at least it resolves
some memory leaks like: harbour -n -w3 tbcolumn.prg

! fixed reported by -w3 repeated aDir declaration
* harbour/source/rtl/tbrowse.prg
* calculate frozen area size for 5-th element of array returned
by xbase++ compatible method :viewArea(). Viktor please check me.
If you can also describe what exactly TOFIX in :firstScrCol()
and :viewArea() means then maybe I can help - I do not have
xbase++ so I do not know what should be fixed.
* harbour/include/hbclass.ch
! removed:
MESSAGE <msgName> IS <mthName>
used as synonym of:
MESSAGE <msgName> METHOD <mthName>
If someone was using the removed version then please update the
code to MESSAGE ... METHOD ...
The removed command has special meaning in Class(y) and it allow
to define alternate names for existing messages. I'll add support
for them in the future.
* harbour/contrib/hbct/ctwin.c
* added disabled code which is a workaround for some possible
bad side effect caused by online shadow showing by CTWIN.
* harbour/source/rtl/errorint.c

* harbour/include/hbexprb.c
* harbour/source/common/expropt1.c
* harbour/source/common/expropt2.c
+ added hb_compExprReduceNegate()
! fixed wrong negate optimizations for platforms where HB_LONG_MAX
is smaller then -HB_LONG_MIN, f.e. all x86 based CPUs.
! fixed setting the size in optimized negative numbers
! fixed some math optimizations to not use casting to double value
when it's not necessary - when double precision is smaller then HB_LONG
(f.e. on x86 it's 53 bits and HB_LONG has 64bit) such casting can damage
up to 11 less significant bits in big 64 bit numbers.
* harbour/source/rtl/hbinet.c
* replaced MAKEWORD() macro with HB_MKWORD() to pacify BCC58 warnings
* harbour/include/hbdefs.h
+ added #include <limits.h>
It should hide some warnings related to redefined integer size constants
Viktor if it will not help for BCC58 warnings then you will have to add
#include <stdint.h>
few lines below but please remember that older BCC version does not
have it so check for the exact compiler version.
! changed macros which setting default numeric item size for more strict
Clipper compatible mode. I'm not a fun of some Clipper behavior in
calculating number size and I left some notes about it in hbdefs.h
Anyhow this and some other modifications below should cover the
differences you've found recently. Some things are not addressed by
me intentionally, f.e. _itemPutNL() in Clipper always set size to 10
without checking the maximum size so it's too small for values less
then -999999999. Harbour compiler makes more compile time optimizations
then Clipper. The formatting rules used by compiler are a little bit
different then by VM so this can be source of some other differences
to Clipper. I can easy create some examples. Harbour supports 64bit
signed integers and Clipper doesn't. This is yet another situation
when we may have different results then Clipper. Most of them can
be hidden if we add new PCODE(s) for integer number with explicit
size but I do not think it's such important to increase PCODE list.
In few cases it will be necessary to disable some optimizations at
all and I do not like it. In the future when I will be adding some
new optimizations I also add compiler switch to disable/enable
optimizations which can have such side effects for people who need
strict formatting.

Now hbppgen creates in include directory hbverbld.h file with
information extracted from ChangeLog. New hbppgen parameters:
Syntax: ./hbppgen <file>[.prg] [options]
Options: -i<path> add #include file search path
-c[<file>] look for ChangeLog file
-o<file> creates .c file with PP rules

* harbour/include/hbexprb.c
* replaced // comments by /* */
* accept <cContext> (domain) parameters of HB_i18nGettext() when

ON ERROR FUNCTION <FuncName>
OPERATOR <op> FUNCTION <FuncName> <scope>
* harbour/include/hbapicls.h
* harbour/source/vm/classes.c
* harbour/source/vm/hvm.c
+ added support for overloading right side $ operator
* harbour/contrib/xhb/xhbfunc.c
* rewritten xhb_ains() and xhb_adel() in C
* harbour/contrib/xhb/xhb.ch
* changed AINS() conversion to be xHarbour compatible
* harbour/contrib/xhb/Makefile
+ added xhb.ch to PRG_HEADERS so it's installed automatically
during 'make install'
* harbour/contrib/xhb/Makefile
+ harbour/contrib/xhb/xhbmsgs.c
* harbour/contrib/xhb/xhbcomp.prg
+ added support for $ operator used with hashes and arrays
on right side working _exactly_ like in xHarbour.
+ added support for negative indexes in used in [] operator
for array and strings.
Please remember that standard harbour build (without
HB_COMPAT_XHB flag) generate warning for negative indexes,
if you wan to pacify them then instead of var[-1] use var[(-1)]
+ added support for assign string characters with [] index.
Please remember that for standard harbour build (without
HB_COMPAT_XHB flag) you have to use -ks compile time switch
if you want to assign strings in such way because this feature
needs different PCODE, f.e. try to compile this code:
proc main()
local s:="ABC"
s[(-1)] := "*"
? s
return
with and without -ks switch
+ added support for accessing hash items using OO interface, f.e.:
proc main()
local h:={"ABC"=>123.45,"XYZ"=>567.89}
? h["ABC"], h["XYZ"]
? h:ABC, h:XYZ
h:ABC+=1000
h:XYZ:=-2000
? h:ABC, h:XYZ
return
All of the above extensions are written in C code so the speed
overhead is very small. Harbour evaluates PCODE faster then xHarbour
so in speed tests where above operators are executed in loop without
any other code the xHarbour results with native support are comparable
with Harbour ones where above operators are overloaded using scalar
classes so in normal code you should not find any difference with
one exception for assigning characters in very long strings.
* harbour/include/hbclass.ch
+ added new commands for scalar classes:
ASSOCIATE CLASS <ClassName> WITH TYPE
ARRAY|BLOCK|CHARACTER|DATE|HASH|LOGICAL|NIL|
NUMERIC|POINTER|SYMBOL
ENABLE CLASS TYPE ALL
ENABLE TYPE CLASS ARRAY|BLOCK|CHARACTER|DATE|HASH|LOGICAL|NIL|
NUMERIC|POINTER|SYMBOL
Please remeber that:
ENABLE CLASS TYPE ALL
and:
ENABLE TYPE CLASS ...
can be used in any place of code - this commands are translated to
REQUEST HB<TYPENAME>
so are not executed
* harbour/source/vm/classes.c

+ harbour/source/rtl/tscalarb.c
+ harbour/source/rtl/tscalarn.c
+ harbour/source/rtl/tscalarc.c
+ added scalar classes for basic types,
Now it's possible to define messages also for basic item types.
It's even possible to overload some not defined in HVM operators,
f.e. in this example we overload operator "+" so it makes
AADD( <aValue>, <xValue> )
for code like <aValue> + <xValue>:
#include "hbclass.ch"
PROC MAIN()
LOCAL a:={}
ASSOCIATE CLASS MyArray WITH TYPE ARRAY
a := a + "elem1"
a += "elem2"
a := a + "elem3"
a += "elem4"
? a:asString, a:isScalar
AEVAL(a,{|x,i|QOUT(i,x)})
RETURN
CREATE CLASS MyArray INHERIT __HBArray
OPERATOR "+" ARG xValue INLINE AADD( Self, xValue ), Self
ENDCLASS
Operators which have default actions for given types defined in HVM
cannot be overloaded.
* harbour/include/hbclass.ch

+ New PP code written from scratch. It works in similar way to
Clipper PP even the error codes are replicated. The code is MT
safe does not have any limitation on size of preprocessed code,
line, etc. It's also Clipper compatible lexer. It means that
we do not longer need FLEX or SIMPLEX which can be replaced
by new PP after some small modifications. Anyhow I haven't
decided to make it myself. I would like to agree with with the
rest of developers. I will be very happy if such modifications
will be done by someone else, Ryszard?
Meanwhile I current PP join on output the line tokens and give
the string line to FLEX/SIMPLEX. It does not have any sense and
all FLEX/SIMPLEX limitations are still existing. Ryszard, even
if we keep it then I hope you can remove at least FLEX line buffer
and use the one returned from PP.
Because string tokens in parsed line are converted to text which is
later once again decoded to tokens by FLEX I had to introduce new
string format which supports embedded string delimiters. I chose
modified version of xHarbour extension with escaped strings e"<sting>"
so now FLEX understand such strings and decode them like C escaped
strings. It means that you can use them also in the .prg code f.e.:
outstd( e"Hello\n\rWorld" )
The new PP is also noticeable faster. You should see the difference
compiling long files. The build in PP rules are generated automatically
by ppgen program created from source/pp/ppgen.c
I had to add to GNU source/pp/Makefile these two lines:
pptable.c : ppgen$(EXE_EXT)
./ppgen$(EXE_EXT) $(TOP)$(ROOT)include/hbstdgen.ch -opptable.c -q
Sth like that will have to be done also in non GNU make system.
Now Harbour can be compiled only using GNU make.
Marek can you update non GNU make files? I would like to leave this
modification to you or other developers who can test it.
It was quite big modification and I do not believe that I haven't
make any mistakes but I hope that in few weeks I'll fix any reported
bugs and it will resolve any PP problems.
TODO:
* error messages
create one common list of errors and warnings and keep it
in common library. PP and compiler can still generate different
errors with the same number. It can be confusing for the users
and hard to document and add i18n translations.
If possible we should also try to keep Clipper error numbers.
In new PP code I added Clipper error numbers but I cannot use
them until compiler code is not updated.
We should aslo remove the ctype passed to error functions and
hack with first character in warning messages and use only
error number. The codes from 1000 to 1999 should be warnings
where range 1000:1099 is activated by -w, 1100:1199 by -w1,
1200:1299 by -w2, etc. 2000:2999 are errors and 3000:3999
fatal errors. All compiler functions which generate an error
should expect that error function will not stop the compiler
but return and cleanly finished their job. It's necessary for
MT support in compiler and making compiler part of some other
programs which may still work and compile different source code.
* FLEX/SIMPLEX
remove them at all and add some final pass to PP to create
more precise tokens for grammar parser or at least add better
integration to remove some redundant code and existing limits.
* hb_inLine() support - it's broken in new PP but as I can see
it was never working correctly. I can add a hack to PP to support
hb_inLine() but I'm not sure it's worth to do. Maybe in few days.
+ harbour/include/std.ch
+ added new std.ch. It was created without using Clipper's std.ch.
It's quite possible that some rules are wrong and should be fixed
so please help. Anyhow I created a set of programs based on new PP
code generating all possible combinations of different commands I
collected from different source code, documentation and match patterns
of rules I was adding to new std.ch and then I was comparing .ppo
files generated by Clipper and Harbour so I do not expect any bigger
problems then some minor typos. I had to introduce some modifications
in spacing as workaround for FLEX/SIMPLEX which cannot properly decode
text preprocessed by Clipper after stringify.
* harbour/utils/hbpptest/pretest.prg
* updated for new PP
It reports 16 wrong translations but some of them are valid
and some others are caused by escaped string e"..." (one of hack
for FLEX/SIMPLEX support)
I also had to remove all spaces in comparison the results
because they were not Clipper ocmpatible at all. Ryszard please
look at it.
* 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
* Temporary disabled optimization with references to object variables
until we will not have extended reference items in our HVM.
It can be enabled by compiling with HB_USE_OBJMSG_REF
* harbour/include/hbclass.h
* restored previous CLASSDATA behavior which ignores SHARED clause
and always create shared class variables
* harbour/include/hbclass.ch
* most of the rules rewritten
! fixed some wrong rules and general cleanup
+ added additional code validation
! fixed compilation of more then one class in single file.
Now it's even possible to declare all classes at beginning of
single file and then implementing their methods in any order
! fixed using static classes and classes
! fixed compilation without <ClassName>_ prefix in method names
+ added support for HB_CLS_NO_DECORATION macro which disable
adding <ClassName>_ prefix to method names - this macro is
set by default when HB_SHORTNAMES is set.
+ added support for declared parameters validation - it can be
disabled with HB_CLS_NO_PARAMS_ERR and I had to disable it
by default due to problems with our preprocessor.
Ryszard seems that our PP has serious problems with decoding
directives when there is no space between symbol and some other
non symbol character. I had to add some workarounds and even
introduce buggy rules to make it working. Please look at it.
You can remove #define HB_CLS_NO_PARAMS_ERR from hbclass.ch
and try to rebuild Harbour core code to see the problem.
* harbour/include/hboo.ch
* harbour/source/vm/classes.c
+ added support for new primitive message: HB_OO_MSG_PERFORM
* harbour/source/rtl/tclass.prg
- removed <lPersistent> parameter from HBClass messages and
internals data. Persistent is supported as scope bit and
separate variable was redundant.
- removed stripping of () from message names. Here is not a place
to fix wrong preprocessor rules.
* harbour/utils/hbtest/rt_class.prg
* use: METHOD PROCEDURE ... CALSS ...
instead of: PROCEDURE ... CALSS ...
The first version is preferable syntax.
* harbour/source/debug/dbgtmenu.prg
* harbour/source/rtl/checkbox.prg
! fixed some parameters in method declaration - global cleanup
will have to wait for preprocessor fixes
Hi all,
Please make test with current hbclass.ch code.
I hope that I haven't broken too much things ;-) but I rewrite
from scratch most rules and it's possible that I missed sth or
made some stupid typos. Current version is much shorter and should
be easier to updated. For sure I've intentionally changed one thing.
CLASSDATA was ignoring SHARED attribute and always created shared
class variables. Seems that it was long existing typo but the fix
may interact with already existing code which needs SHARED class
variables but does not use SHARED clause in CLASSDATA declaration.
In such case please update it and add missing SHARED.
Also in the end of CLASS declaration we have:
[ ; #translate Super( <SuperClassN> ): => ::<SuperClassN>: ] ;
[ ; #translate Super( <SuperClass1> ): => ::<SuperClass1>: ] ;
[ ; #translate Super(): => ::<SuperClass1>: ] ;
[ ; #translate Super: => ::<SuperClass1>: ] ;
[ ; #translate ::Super : => ::<SuperClass1>: ]
These rules introduce very serious bug - they are breaking supercasting
in code which makes sth like:
::super:super:super:msg
or in any other code which sends SUPER message to some other class
objects. I will have to remove them. At least the last three ones.
There were some other things I wanted to write about but it's too late
and I'm to tired - sorry. If you will have any question please ask. if
you will notice some problems with current rules please inform me.
* harbour/include/hbclass.ch
* updated some not enabled by default rules to use function pointers
instead of function names which I forgot to update in previous
commit
* harbour/include/common.ch
+ added ISSYMBOL()
* harbour/include/hbextern.ch
- removed __CLS_PARAM()
* harbour/include/hbclass.ch
* harbour/source/rtl/tclass.prg
* harbour/source/vm/classes.c
* replaced __CLS_PAR00() and __CLS_PARAM() functions by preprocessor
rules. These functions are not longer necessary though I left them
in classes.c for backward binary compatibility. Probably they will
be removed in the future.
! use function pointers (@<funcname>()) instead of function names
with REQUEST for super classes ID. It fixes using STATIC class
functions.
* 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/doc/destruct.txt
+ added description for object destructors in Harbour
* harbour/include/error.ch
+ added new error code EG_DESTRUCTOR
* harbour/source/lang/msgpl852.c
* harbour/source/lang/msgpliso.c
* harbour/source/lang/msgplmaz.c
* harbour/source/lang/msgplwin.c
* harbour/source/rtl/langapi.c
+ added desription for new error code - other language modules
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
! fixed possible RT error generation when some exception is active
* harbour/include/hbapicls.h
* 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/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
* source/pp/ppcore.c
+ Added logic for new Idenitifier Match Marker <!AnyId!> which will only match Identifiers.
+ Added static BOOL IsIdentifier( char *szProspect )
* include/hbclass.ch
! Changed <name> to <!name!> in 3 VO OO compatibility rules, where regular match marker was TOO generic.
! Reinstated default #define HB_CLS_VO
* contrib/dot/pp.prg
* Added support fort '|' as a continuation token (as in Clipper).
* include/hbclass.ch
- Commented out 3 rules used for VO OO compatibility that are TOO generic, and match unexpected input.
* source/pp/ppcore.c
- Recommented out test for continuation token at the end of an Expression in isExpres() (after correcting cause for prior reinstatment).
