* harbour/ChangeLog
! corrected previous ChangeLog entry: instead of hb_waDetach()/
hb_waRequest() should be db_dbDetach()/hb_dbRequest()
* harbour/source/vm/hvm.c
* disabled PRG tracing in default builds. If someone wants to
use this feature then he should recompile Harbour with HB_PRG_TRACE
macro. In such case tracing can be enabled/disabled by __TRACEPRGCALLS()
function. HB_NO_TRACE macro is not longer usable - it's default in
current code.
* harbour/source/vm/classes.c
+ added PRG function __clsPreallocate() which extends the size of
classes buffer to given value to avoid later RT reallocations.
It may be useful in some very seldom cases for MT programs which
will allocate dynamically at runtime more then 16386 classes.
In practice rather impossible though who knows ;-)
* harbour/source/rdd/workarea.c
* set default preallocation size for RDD nodes to 128
+ added PRG function __rddPreallocate() which extends the size of
RDD nodes buffer to given value to avoid later RT reallocations.
It may be useful in some very seldom cases for MT programs which
will register dynamically at runtime more then 128 RDDs when other
threads are active and may use RDD nodes.
* harbour/include/hbrddcdx.h
* harbour/source/rdd/dbfcdx/dbfcdx1.c
+ added ORDLSTDELETE() method.
Now ordbagClear() should work for DBFCDX.

casted to PHB_ITEM - new memvar references
* changed HB_DYNS declarations for MT mode. In MT mode HB_DYNS does
not contain area and memvar handles which are moved to thread
local HVM stack
+ added array for thread local memvar and area handles to HVM stack
% eliminated global continues array with all memvars and detached locals
% changed HB_IT_MEMVAR to use pointers to HB_ITEM directly - it resolve
synchronization problems in MT mode and should also improve the speed
and reduce memory usage. It should be well visible in applications which
uses lot of detached locals.
- removed hb_memvarsInit() and hb_memvarsFree() - they are not necessary
now because we do not longer use array with all allocated memvars
and detached local and private stack initialization is made
automatically

* moved hb_fsCurDir() to HVM stack with special handling to work
with HVM stack like IO errors
* harbour/source/rdd/workarea.c
* allocated RDD node array in bigger peaces to reduce later RT
reallocations in MT mode. If user want to add dynamically more
then 64 RDDs then it should synchronize this operation himself.

* moved WA list, current WA, default RDD and neteer() flag to HVM stack
* harbour/include/hbdefs.h

memvar handling
* updated hb_struMemvar to new memvar handling
* replaced hb_vmIsLocalRef() and hb_memvarsIsMemvarRef() with
hb_vmIsStackRef() which respect multiple stack and new memvar
and static structures and location in GC mark pass.
* harbour/include/hbstack.h
* harbour/source/vm/estack.c
* harbour/source/vm/hvm.c
+ added support for thread specific data located on HVM stack
Now it's possible to allocate static variables which are
local to thread. Such variables are allocated on HVM stack
and automatically destroyed. To declare new TSD variable use:
HB_TSD_NEW( <name>, <size>, <init>, <destruct> )
<name> - name of variable which holds TSD handler
<size> - size of TSD are which has to be allocated
<init> - init function, executed when new TSD is allocated by thread
(thread access given TSD 1-st time). This function receives
void * pointer to allocated area.
<destruct> - destructor function executed when HVM stack is destroyed
f.e.:
static HB_TSD_NEW( s_scrData, sizeof( HB_SCRDATA ),
NULL, hb_xSaveRestRelease );
To initialize dynamically allocated TSD variable use:
HB_TSD_INIT( <name>, <size>, <init>, <destruct> )
Pointer to TSD can be accessed using hb_stackGetTSD( &<name> )
where <name> is name of variable which holds TSD handler, f.e.:
PHB_SCRDATA pScrData = ( PHB_SCRDATA ) hb_stackGetTSD( &s_scrData );
See source/rtl/xsavescr.c as an example
It's also possible to test if data has been already allocated for
current thread by:
hb_stackTestTSD( &<name> ) => pData
it works like hb_stackGetTSD() but return NULL if current thread data
has not been allocated yet.
* harbour/include/hbstack.h
* harbour/source/vm/estack.c
* changed hb_stack location to thread local storage in MT mode
+ added functions and macros to access/assign new HVM stack members
+ changed garbage collection mark functions to work with multiple
stacks, thread local static and memvar variables
* harbour/source/rtl/xsavescr.c
* use TSD data for screen buffer to make __XSAVESCREEN()/__XRESTSCREEN()
thread independent
* harbour/source/rtl/idle.c
* use TSD data for idle task settings and codeblocks
- removed hb_idleShutDown() - it's not longer necessary
* harbour/source/rtl/setkey.c

necessary, allocated resources will be freed by TSD destructor
function
* harbour/include/hbapi.h
* harbour/source/rtl/console.c
* removed hb_conXSaveRestRelease() - it's not longer necessary,
allocated resources will be freed by TSD destructor function

* harbour/source/vm/hvm.c
+ added new PCODE HB_P_THREADSTATICS
+ added support for static variables which are local to thread:
THREAD STATIC <varname [:= <exp>], ...>
They work like normal static variables but each thread operates
on its own copy.
* added protection against possible double call to hb_xfree()
It can happen due to wrong marking expressions as used by bison
and executing destructors after our free code when syntax error
appear.

* harbour/include/hbgtcore.h
* harbour/source/rtl/hbgtcore.c
+ added hb_gt_BaseFree() which will release current GT pointer
locked by hb_gt_Base() function. This function will be used
to optional automatic GT access synchronization when threads
share the same GT.
* harbour/source/rtl/gtapi.c
* harbour/source/rtl/inkeyapi.c

TODO: CTWIN is not MT safe yet - it will be updated together
with core GT when we add multi window interface for
thread with own console window.
* harbour/bin/hb-func.sh
* harbour/config/linux/gcc.cf
+ added rt lib to Linux builds
* harbour/bin/postinst.sh
* create MT safe version of FM stat library: fmmt
* harbour/bin/pack_src.sh
+ added support for ZIP packing
* harbour/include/hbapi.h
* harbour/include/hbvm.h
* harbour/source/vm/hvm.c
+ added hb_vmThreadInit()/hb_vmThreadQuit() functions - they initialize
HVM for calling thread so it can execute .prg code and call HVM
functions. They can be used by 3-rd party code threads.
+ added hb_vmUnlock()/hb_vmLock() functions which informs that
thread will not operate on HVM structures for some time allowing
to execute single thread only processes like GC.
+ added hb_vmThreadQuitRequest() which sends stop request to given
thread
+ added hb_vmWaitForThreads() which stops main thread execution waiting
for other threads
+ added hb_vmSuspendThreads() and hb_vmResumeThreads() used be GC
to stop all HVM threads before mark/swap scan
+ added linked list of HVM stacks
+ added hb_vmTerminateThreads() used by main HVM thread in QUIT state
* moved EXIT procedures execution from QUIT request to HVM QUIT state
in MT mode. It may effects some non structural code which tries to
access private variables in EXIT functions but it's much cleaner
and understandable for user. Please remember that we guaranties
that ALWAYS code in BEGIN SEQUENCE is _always_ executed even after
HVM QUIT request just like destructs. Personally I think that we
should move EXIT procedures execution also in ST mode.
* changed startup and cleanup code for new internal structures
* changes startup and cleanup code for MT mode
% removed some redundant HB_ITEM type settings
! eliminated non MT safe code which was using reference counters
without protection
* harbour/common.mak
* harbour/source/vm/Makefile
+ harbour/include/hbthread.h
+ harbour/source/vm/thread.c
+ added C level functions to manage threads and synchronization objects
See hbthread.h for detail description. They are based on PTHREAD API
and PTHREAD documentation can be used as reference. I intentionally
keep this list small for easier multiplatform porting.
Now they have been implemented for PTHREADS (POSIX threads supported by
many different OSes), MS-Win32/64 and OS2. The OS2 version is not tested
at all. I do not even know if it can be compiled so please make tests.
I used Internet resources and some part of xHarbour code as documentation
for OS2 MT API. It should be quite easy to add other platforms if necessary.
Harbour core code needs non recursive mutexes, conditional variables and
TLS for one pointer. If platforms does not support conditional variables
(f.e. MS-Win or OS2) then they can be emulated using multistate semaphores.
+ added .prg functions to manage threads and synchronization objects:
hb_threadStart( <@sStart()> | <bStart> [, <params,...> ] ) -> <pThID>
hb_threadJoin( <pThID> [, @<xRetCode> ] ) -> <lOK>
hb_threadDetach( <pThID> ) -> <lOK>
hb_threadQuitRequest( <pThID> ) -> <lOK>
hb_threadWaitForAll() -> NIL
hb_mutexCreate() -> <pMtx>
hb_mutexLock( <pMtx> [, <nTimeOut> ] ) -> <lLocked>
hb_mutexUnlock( <pMtx> ) -> <lOK>
hb_mutexNotify( <pMtx> [, <xVal>] ) -> NIL
hb_mutexNotifyAll( <pMtx> [, <xVal>] ) -> NIL
hb_mutexSubscribe( <pMtx>, [ <nTimeOut> ] [, @<xSubscribed> ] ) -> <lSubscribed>
hb_mutexSubscribeNow( <pMtx>, [ <nTimeOut> ] [, @<xSubscribed> ] ) -> <lSubscribed>
The function list should give similar to xHarbour API but they are not exactly
the same and except of hb_mutex*() functions which should replicate xHarbour behavior.
+ harbour/source/vm/vmmt
+ harbour/source/vm/vmmt/Makefile
+ added hbvmmt library to GNU make builds.
Non GNU make builds should be updated.

! fixed casting
* harbour/contrib/gtwvg/gtwvg.h
- removed #include <comctl32.h> - my MinGW and MinGW/CE instalations do
not have them. If it exists in some newer ones then it has to be
covered by #if version checking.
* harbour/source/vm/dynsym.c
- removed hb_dynsymLog() and hb_dynsymMemvarHandle()
* modified code to be MT safe and improved speed of some operations
* added MUEXT protection for global dynamic table access
* harbour/include/hbapi.h
* harbour/source/vm/garbage.c
* changed to work with MT HVM
* changed to work with new memvar structures and thread local static and
memvar variables
* added MUEXT protection for linked block lists
+ added parameter to hb_gcCollectAll() which will force GC activation
in MT mode by temporary suspending all executed threads.
+ added logical parameter to HB_GCALL() functions which is passed to
hb_gcCollectAll()
* harbour/source/vm/fm.c
* added MUEXT protection for FM statistic module
* added MT protection for reference counters. For platforms
which supports atomic incrmenetation/decrementation (f.e.
Interlocked*() functions in MS-Win) such operations are
used. For other it's MUTEX protection. It gives MT safe
readonly access for HVM complex variables without user
synchronization. The MUTEX protection can cause some speed
overhead so it's good to define MT safe version of
HB_ATOM_INC()/HB_ATOM_DEC() in hbthread.h if given platform
has them. Now they are defined only for Windows. For other
platforms We can define can define them in assembler for some
most popular CPUs in the future.
* harbour/source/vm/classes.c
* changed class definition array. Now it keeps pointers to class
structures.
* In MT mode allocated at HVM startup big enough array for class
definitions to avoid later RT reallocations. It effectively eliminates
MUTEX synchronization for class structure access.
* protect by MUTEX code for new class creation
* harbour/source/debug/dbgentry.c
* eliminated hbvmopt.h and direct accessing to HVM structures
* harbour/source/rtl/gtclip.c

+ harbour/tests/mt/mttest05.prg
+ harbour/tests/mt/mttest06.prg
+ harbour/tests/mt/mttest07.prg
+ added some demonstration/test small MT programs written
using Harbour language. Some of them can be also compiled
by xHarbour but xHarbour does not pass any of my tests in
real multi-CPU machine so do not expect they will work
correctly.
Harbour threads needs OS threads support. Each Harbour thread is directly
mapped to OS thread. It's not very efficient on some older system where
cost of thread creation and/or task switching is very expensive but it
should not be bigger problem for modern OS-es which can support threads
in practice nearly in user space only.
I haven't touched Harbour function calling convention which comes from
Clipper. It means that we do not pass pointer to VM to each functions
like CLIP or xBase++. To resolve the problem I have to use thread local
storage (TLS) where such pointer is kept. If platform does not support
TLS then it can be emulated by us. Anyhow the speed of accessing TLS
data and extracting HB_STACK poitner is critical for performance.
Some compilers depending on used hardware and OS give native support
for TLS (f.e. __thread keyword in GCC/BCC or __declspec( thread ) in MSVC).
This should give optimal performance. On other Harbour uses TLS functions
like TlsGetValue() (MS-WIN) or pthread_getspecific() (PTHREAD) are used.
OS2 gives quite interesting TLS functionality which seems to be quite fast
though it will be interesting to know how it is iplemented internally for
real multi CPU machines (if it depends on CPU exception then the
performance will be bad). We need TLS only for one pointer to HB_STACK
structure.
I haven't added any tricks like HB_THREAD_STUB in xHarbour to reduce
the cost of TLS access. If it will be necessary for some platform the we
can add it.
Except TLS Harbour threads needs OS support for non recursive mutexes or
critical sections and conditional variables. If platforms does not support
conditional variables (f.e. MS-Win or OS2) then they can be emulated using
multistate semaphores. I intentionally didn't create code which may need
recursive mutexes. The non recursive ones are often faster and some
platforms may not support recursive mutexes so they will have to be
emulated by us.
Harbour uses reference counters for complex variables. It means that even
readonly access to complex item causes internal write operations necessary
to increment/decrement its reference counter. To make such readonly access
MT safe we have to make incrementation and decrementation with result
checking atomic. By default it's done by mutex inside vm/fm.c but some
platforms have native support for atomic inc/dec operations, f.e.
Interlocked*() functions in MS-Win. If they are available then such
functions should be used to not reduce the performance by mutex call
very often used functions. For many CPUs it should be quite easy to
implement such atomic inc/dec functionality in assembler. F.e. for
GCC and x86@32 it may looks like:
static __inline__ void hb_atomic_inc32( volatile int * p )
{
__asm__ __volatile__(
"lock incl %0"
:"=m" (*p) :"m" (*p)
);
}
static __inline__ int hb_atomic_dec32( volatile int * p )
{
unsigned char c;
__asm__ __volatile__(
"lock decl %0"
"sete %1"
:"=m" (*p), "=qm" (c) :"m" (*p) : "memory"
);
return c == 0;
}
and then it's enough to define in hbthreads.h:
#define HB_ATOM_INC( p ) hb_atomic_inc32( ( volatile int * ) p )
#define HB_ATOM_DEC( p ) hb_atomic_dec32( ( volatile int * ) p )
Probably I'll make it for some most popular CPUs in the future.
In Harbour each thread which wants to call HVM functions have to allocate
it's own HVM stack. It's done hb_vmThreadInit(). The HVM stack is freed
by calling hb_vmThreadQuit(). This functions can be called also by 3-rd
party threads if they want to call HVM functions or execute .prg code.
Calling HVM functions without allocated stack will cause GPF.
I moved most of static variables to HVM stack to make them thread
local. But some of them like FS errors have their own alternative
copy which is used when thread does not allocate HVM stack. It allows
to use hb_fs*() functions without HVM stack but programmer have to
know that error codes return by hb_fs*Error() functions can be
overwritten by other threads which also didn't allocated HVM stack.
To execute garbage collector scan and mark pass it's necessary to
stop other HVM threads. Otherwise the scan may give false results.
It's also possible to not stop threads but protect with mutex all
operations on GC items but it will probably cause performance reduction
and will force some other modifications. Maybe I'll implement it
in the future.
I didn't use any OS level thread KILL or CANCEL calls. All HVM threads
have to be cleanly removed without any resource leaks.
QUIT command terminate only calling thread. If main (startup) HVM
thread call QUIT then it sends QUIT request to all existing threads.
In QUIT state ALWAYS statements and destructors are executed.
New thread is created by:
hb_threadStart( <@sStart()> | <bStart> [, <params,...> ] ) -> <pThID>
The returned value is a pointer to internal thread structure which
can be used in JOIN or DETACH operations. Each thread should be Joined
or DETACHED to avoid resource leaks. If programmer does not store
<pThID> or all instances of <pThID> are destroyed then thread is
automatically detached. I do not know clear method of thread detaching
in OS2. If some OS2 users knows it then plase update vm/hbthread.c.
When thread terminates then all locked by this thread mutexes are
released.
Each thread uses its own memvars (PRIVATEs and PUBLICs) and work areas.
When new thread is created then it inherits from parent thread:
- code page
- language
- SETs
- default RDD
error block is initialized to default value by calling ERRORSYS()
and PUBLIC variable GetList := {} is created.
The following objects are initialized to default value:
- error block
- math error handler and math error block
- macro compiler features setting (hb_setMacro())
or move them to SETs.
We can think about inheriting them. It's also possible to add
inheriting of all visible memvars but I do not know it's good
idea.
Compilation and linking:
For MT mode HVM library should be compiled with HB_MT_VM macro.
GNU make automatically creates hbvmmt library which should be
linked with Harbour MT programs instead of hbvm.
Non GNU make files should be updated.
If given compiler support TLS then you can try to set HB_USE_TLS
to force using native compiler TLS support. Now it's enabled by
default only for BCC. For Linux and GCC builds it may depend also
on used GLIBC version. In older system there is no TLS support
at all or TLS works only for shared binaries so I haven't enabled
it. If you will test some other compiler then please add default
native TLS support for them in hbthread.h
Users using hb* scripts can simply use -mt switch when they want
to create MT program, f.e.:
hbmk -n -w3 -es2 -mt mttest01.prg
There are still some minor things which should be done but I'll
do them later. Current state seems to be fully functional.
The most important and still missing is our own file lock server
for RDD synchronization in POSIX systems. Kernel internally
recognize POSIX locks by PID and file i-node - not PID and file
handle. It means that the same file open more then once by one
process shares locks. Because POSIX locks can be overwritten
then we do not have any synchronization between aliased workareas
or threads using the same table in *nixes. We have to make
synchronization ourselves. I'll create such lock server ASAP.
Please test and enjoy using Harbour threads.

! non-GNU make will also look into the /bin folder

! Lots of fixes, too many to mention.
+ Enabled GC pointers. (see TOFIX though)
+ Added all remaining CURL 'easy' API parts and
implemented all options existing in 7.18.1:
+ All option values (except bit-level ones) made available in hbcurl.ch
+ All options updated to latest CURL version in hbcurl.ch
+ All error codes made available in hbcurl.ch
+ CURL_EASY_DUPLICATE()
+ CURL_EASY_RESET()

+ CURL_EASY_RECV() (not yet available in stable builds)
+ CURL_EASY_GETINFO()
+ CURL_ESCAPE() (obsolete)
+ CURL_UNESCAPE() (obsolete)
+ CURL_GETDATE()
; TOFIX1: Could someone look at it? In case I call the destructor
(curl_easy_cleanup()) manually, the garbage collector
will run into an invalid pointer, when terminating the
test program.
; TOFIX2: The casting to 'curl_off_t' goes wrong. Could someone
help?
; NOTE1: Harbour needs at least libcurl 7.17.0. Unfortunately
compile time version detection is not working at this time,
so try with the latest version 7.18.1.
; NOTE2: Most callback interfaces are not implemented on the
Harbour level.
; NOTE3: Harbour is currently not optimizing
"<const1> ** <const2>" type of expressions at compile time.
Could we add it? This expression is not widespread,
but anyways, it cannot hurt, if isn't too much
work to do.

+ added new function hb_dbgObjSendMessage() which allows to
call messages with given given execution context for proper
scope checking
* harbour/source/debug/dbgentry.c
+ added HB_DBG_SENDMSG() for calling messages with given execution
context
* harbour/source/debug/dbgtobj.prg
* removed all __obj*() function calls
* use HB_DBG_SENDMSG() to access/assign object variables
! fixed default value in GET operation called from object
inspector to always show current object variable value
! fixed set for object variables which hold value: "Method"
they were recognized as method
Now object variables can be inspected by debugger.
If object has multiple private messages with the same name
inherited from parent classes then their context will be
dynamically changed depending on position in currently
debugged code.

* harbour/contrib/hbct/screen2.c
! fixed possible vary bad bug (memory buffer overflow) in SCREENSTR()
* harbour/source/rtl/hbffind.c
! fixed possible GPF in some *nixes
* harbour/source/vm/classes.c
! do not execute the same destructor inherited from different parent
classes more then once
* harbour/source/rtl/transfrm.c
! fixed bug with '9' used as stop condition of function pattern
this character cannot be stripped, f.e.:
? transform( "abc", "@_99*" )
! fixed bug with '*' or '$' used with @), f.e.:
? transform( -12345, "@) $999999" )
! fixed replacing '.' with ',' when @E is used without picture part, f.e.:
? transform( 123.45, "@E" )
! fixed ',' conversions
? transform( 12.34,"@E ab,cd.ef9,9.99,.--" )
! fixed bug with picture starting with ".", f.e.:
? transform( 0.3456, ".999" )
! fixed "@(" and "@)" conversions, f.e.:
? transform( -12345, "@) 1999*999" )
! fixed late oveflow detection in "@(" and "@)", f.e.:
? transtest( -12345, "@( 6798^999" )
! fixed "@E" conversion for dates to keep user delimiters set in
_SET_DATEFORMAT, f.e.:
set( _SET_DATEFORMAT, "mm:dd:yyyy" ); ? transform( date(), "@E" )
set( _SET_DATEFORMAT, "yyyy<mm>dd" ); ? transform( date(), "@E" )
Please note that Harbour is not strictly Clipper compatible here
because it respects _SET_DATEFORMAT set by user.
! fixed 64bit integer conversion by eliminating conversion to
'double' f.e.:
? transform( 1234567890123456789, "99999999999999999999" )
? transform( -1234567890123456789, "99999999999999999999" )
! some other fixes, see regression test transtst.prg
% speed improvement in numeric conversions
+ harbour/tests/transtst.prg
+ added regression test for transform function
* harbour/utils/hbtest/rt_trans.prg
* disabled transform() tests for "@E" and result smaller then 5 bytes
CA-Cl*pper do not check result size and always exchanges
bytes 1-2 with bytes 4-5 for @E conversion. It's buffer overflow
bug and I do not want to replicate it inside our transform
implementation. It also causes that the results for for strings
smaller then 5 bytes behaves randomly.
In fact precise tests can show that it's not random behavior
but CA-Cl*pper uses static buffer for result and when current one
is smaller then 5 bytes then first two bytes are replaced with
4-5 bytes from previous result which was length enough, f.e.:
? transform( "0123456789", "" )
? transform( "AB", "@E" )
? transform( "ab", "@E" )
Replicating exact CA-Cl*pper behavior it's trivial (it will be enough
to use static buffer two and not check the size of current result) but
IMHO it's bug.

CP initialization in some GTDs which can work in both mode depending
on client side settings
* harbour/source/rtl/gttrm/gttrm.c
* improved UTF-8 detection

* harbour/include/hbapi.h
* harbour/source/vm/itemapi.c
* harbour/source/vm/garbage.c
+ added extended item references - it's universal reference which
can be used by HVM for many different things without introducing
new item types
* harbour/include/hbexprb.c
* respect -ks compiler also with <op>=, --, ++ operators
* harbour/include/hbvm.h
* harbour/source/vm/hvm.c
* harbour/source/vm/classes.c
+ added extended references for SETGET methods used as object
item references
* use extended references to respect overloaded [] operator in
object item references
+ added support for passing indexes to string item characters
( @cValue[n] ) by reference using extended references - extension
enabled by -ks compiler switch and //flags:s RT switch.
+ added hb_vmPushItemRef()
* harbour/source/rdd/dbf1.c
* harbour/source/rdd/usrrdd/usrrdd.c
* use hb_vmPushItemRef()
* harbour/contrib/xhb/xhbcomp.prg
* harbour/contrib/xhb/xhbmsgs.c
* overload +, -, *, %, ^, ++, -- in string and numeric scalar
classes to emulated xHarbour behavior when 1 byte string is
used as numeric value.
Note: <nun> + <char1> in XHB lib gives numeric value when in
xHarbour character. But because <nun> <anyOtherOper> <char1>
in xHarbour gives numeric value then I guess that it's
xHarbour bug and I should not replicate it, f.e.:
proc main()
? 1+"A", 131-"A", 33 * 2, 132 / chr(2), 133 % "C"
return
* overload +, - in hash scalar class to emulated xHarbour behavior
for <hash> + <hash> and <hash> - <hash>
Seems that now we can remove HB_COMPAT_XHB flag from HVM and keep
Harbour compatibility only with -ks compile time switch and XHB
library. Please make some tests with Harbour compiled without
HB_COMPAT_XHB and xHarbour code using REQUEST XHB_LIB. It's possible
that I missed sth but some basic test shows that our emulation is
better then original and addresses places where xHarbour does not
work at all or gives strange results, f.e.:
#ifndef __XHARBOUR__
request XHB_LIB
#endif
proc main()
local h:={"ABC"=>123.45}
? h:abc
h:abc+=1000 ; ? h:abc
h["ABC"]+=1000; ? h:abc
p(@h:abc) ; ? h:abc
p(@h["ABC"]) ; ? h:abc
return
proc p(x)
x+=1000
return
or:
#ifndef __XHARBOUR__
request XHB_LIB
#endif
#include "hbclass.ch"
proc main()
local o:=myClass():new()
o:setget:="ABC"; ? o:setget
o:setget[2]:=42; ? o:setget
o:setget[2]+=42; ? o:setget
? o:setget[2]+=42; ? o:setget
?
o:var:="ABC"; ? o:var
o:var[2]:=42; ? o:var
o:var[2]+=42; ? o:var
? o:var[2]+=42; ? o:var
return
CREATE CLASS myClass
VAR var
METHOD setget SETGET
END CLASS
METHOD setget( xNewVal ) CLASS myClass
IF pcount() > 0
::var := xNewVal

RETURN ::var

* harbour/include/hbclass.ch
+ added:
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.

Unlike Ads*() functions the Sx_*() ones can be used with any RDD
and will work if RDD supports necessary functionality.
The global settings in SIx3 are RDD dependent in Harbour, f.e.
in SIx3 Sx_MemoExt() change MEMO file extensions in all SIX* RDDs
but in Harbour only in default RDD driver.
In Harbour default trigger function "Sx_DefTrigger" is not
enabled by default. If user needs such functionality then he
has to enable it himself using
rddInfo( RDDI_TRIGGER, "SX_DEFTRIGGER", [<cRDD>] )
f.e. this code:
init procedure sx_inittrig()
local aRDDs := { "DBF", "DBFNTX", "DBFCDX", "SIXCDX", ;
"RMDBFNTX", "RMDBFCDX" }
local aRDDList := RddList(), cRdd
for each cRdd in aRDDs
if ascan( aRDDList, { |x| x == cRdd } ) != 0
rddInfo( RDDI_TRIGGER, "SX_DEFTRIGGER", cRDD )
endif
next
return
sets SX_DEFTRIGGER as default trigger in DBF* based RDDs.
I still do not allow to encrypt tables with memo fields to not
replicate SIx3 bugs which may cause data corruption.

* 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

+ harbour/source/rtl/tscalaru.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.

of scalar ceases class function is different: 'CSY' in class(y) and
'HB' in Harbour, f.e.: hbNumeric()
If you prefer xHarbour like not automatic scalar class registration
with some PP commands:
ASSOCIATE CLASS <ClassName> WITH TYPE

ENABLE TYPE CLASS ARRAY|BLOCK|CHARACTER|DATE|HASH|LOGICAL|NIL|

Then I can replace current code with it. If not then we should
divide scalar cases definitions into separated files to allow
easier overloading. I'm interesting in your opinions.

! reverted fix for unnecessary -W2 warning:
Function '...' does not end with RETURN statement
in code like:
func f(v)
if v
return "TRUE"
else
return "FALSE"
endif
Sorry but I had to make it because this fix was wrong and causes
that code like:
func f(v)
if v
? v
else
return "FALSE"
endif
was compiled without any warnings but wrong PCODE was generated.
In some spare time I'll try to implement valid RETURN detection,
now simply add RETURN NIL at the end of such functions - it will
be removed by dead code eliminator.
! fixed memory leak when more then one .prg file was given as compiler
parameter

not sure it's good idea anyhow people ask about it so we
have it. Probably we should add some special method like
OnError(), f.e.: OnRestore() or sth like that and execute
it after deserialization or object cloning.

as harbour compiler and makes the same job :-)
* harbour/utils/hbrun/Makefile
* harbour/utils/hbrun/hbrun.prg
+ added support for compilation and direct execution of .prg files
Now hbrun can accept as first parameter .hrb or .prg file and if
it's .prg file it's compiled and then executed just like .hrb one.
In *nixes if you copy compiled hbrun to /usr/bin directory then
you can add to your .prg files as first line:
#!/usr/bin/hbrun
and then after setting executable attribute you can directly
execute them, f.e.:
./test.prg
If you are using Linux then you can also chose default gt driver
by dding to above line: //gt<name>
F.e.
#!/usr/bin/hbrun //gtstd

+ 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.

+ harbour/contrib/tip/tip.ch

+ added TIP library - code borrowed from xHarbour
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)

! 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
* moved one character length string table (hb_szAscii) from hvm.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.

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

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/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/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.

* 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/source/vm/itemapi.c
* minor modification in function order to group together the ones
which can operate on reference counters
+ added additional stop condition in hb_itemUnRef() - we will have
to make some modifications for the code which execute hb_itemUnRef()
to resolve some possible conflicts with operators overloading and
compiler optimizations
* harbour/source/vm/classes.c
* do not inherit friends - seems that our classes code was too
friendly ;-)
It also effectively resolves logical problem with accessing
overloaded non virtual methods from friends.
+ added __clsLock( <hClass> ) - it locks any farther class
modifications and can be used if programmer wants to be sure
that no one will try to hack his class definition. It's very
important when programmers work in a team on bigger project.
Please do not add to CVS any __clsUnLock() functions - if someone
needs it then he can create his own custom HVM build.
* code cleanup
* harbour/source/vm/eval.c
+ added hb_execFromArray() - idea and syntax borrowed from xHarbour's
HB_ExecFromArray() by Giancarlo Niccolai though it's independent
implementation. Now when we have support for functions with variable
number of parameters then we need sth like this function to fully
benefit from new feature. The following syntax is supported:
hb_execFromArray( <cFuncName> [, <aParams> ] )
hb_execFromArray( @<funcName>() [, <aParams> ] )
hb_execFromArray( <bCodeBlock> [, <aParams> ] )
hb_execFromArray( <oObject> , <cMethodName> [, <aParams> ] )
hb_execFromArray( <oObject> , @<msgName>() [, <aParams> ] )
or:
hb_execFromArray( <aExecArray> )
where <aExecArray> is in one of the following format:
{ <cFuncName> [, <params,...>] }
{ @<funcName>() [, <params,...>] }
{ <bCodeBlock> [, <params,...>] }
{ <oObject> , <cMethodName> [, <params,...>] }
{ <oObject> , @<msgName>() [, <params,...>] }
* harbour/source/rtl/symbol.prg
* removed C code inside #pragma BEGINDUMP/ENDDUMP
now it's only .prg code which uses variable parameters function
and hb_execFromArray()

* 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/include/hbdefs.h
* indenting
* harbour/include/hbexprb.c
* harbour/include/hbexprop.h
* harbour/source/common/expropt2.c
+ added compile time optimization for STOD(cConstDateString)
covered by -kh compiler extension (default)
It allows to keep the same source code for Clipper and
Harbour and benefits from data constants without using
0dYYYYMMDD values
* harbour/source/vm/classes.c
* restored the original 3-rd parameter in hb_clsAdd to void(void) -
PHB_FUNC - and added translation for PHB_SYMB to not force using
[P]HB_SYMB in 3-rd party code
* harbour/source/vm/estack.c
* added protection against possible GPF after executing
hb_stackBaseProcOffset() when first item on the stack
was not HB_IT_SYMBOL - it can happen in some seldom
cases. Probably some more general solution like leaving
first dummy item on HVM stack for breaking stack scan
loops will be better. I'll think about it.
* harbour/source/vm/itemapi.c
! fixed clearing enumerators
