that it now gets properly filled with the full
executable file path for console mode (GTWIN)
apps in all situations (f.e. when run from a
batch file using '%~n1.exe' macro).
* source/rtl/hbinet.c
! Fixed to use safe strerror() (named strerror_s())
under MSVS 2005 and upper.
Please test.
* source/hbzlib/gzio.c
+ Added _CRT_SECURE_NO_DEPRECATE locally to suppress
various MSVC unsafe CRT API usage warnings. Maybe it'd
be better to fix these by using Harbour APIs.
* utils/hbdoc/gentrf.prg
! Fixed missing "common.ch"
* harbour/include/hbdefs.h

* Mapping snprintf() calls to hb_snprintf().
; TODO: Replace the calls in source code.
* source/common/hbstr.c
! Fixed hb_snprintf(). Please verify on your platforms.
; TODO: It may need further tweaking to smooth out the
platform implementation differences.
* source/common/hbstr.c
* Some tweaks to hb_snprintf(). It still doesn't work
for some reason.
* include/hbapi.h
+ Added hb_snprintf() to header.
* source/debug/dbgentry.c
* Changed strcpy() to hb_strncpy(). Chances are high
this is wrong. Please review and test.
* harbour/rtl/gtwvt/gtwvt.h
+ Added <ResizeMode> member to HB_GTWVT
* harbour/include/hbgtinfo.ch
+ Added HB_GTI_RESIZEMODE

case HB_GTI_RESIZEMODE:
pInfo->pResult = hb_itemPutNInt( pInfo->pResult, HB_GTI_RESIZEMODE_FONT );
break;
* harbour/tests/wvtext.prg
! Updated to demonstrate K_HB_RESIZE event in navigation loop.
; Odd numbered windows will have HB_GTI_RESIZEMODE_ROWS mode
Even numbered windows will have HB_GTI_RESIZEMODE_FONT mode.
Open two or more browsers to see the effects.
; To activate HB_GTI_RESIZEMODE_ROWS mode call
hb_gtInfo( HB_GTI_RESIZEMODE, HB_GTI_RESIZEMODE_ROWS )
and whenever window will be resized you can retrieve it via
if inkey() == K_HB_RESIZE
// Reconfigure browser/your screen accordingly
endif
* harbour/source/rtl/gtxwc/gtxwc.c
* added hack for problems with some XLIB versions in heavy stress
MT tests
* harbour/include/hbapigt.h
* harbour/source/vm/thread.c
* added parameter to hb_gtAlloc() C function
* harbour/include/hbapigt.h
* harbour/source/rtl/hbgtcore.c
+ added hb_gtCreate() and hb_gtSwap() C functions
+ added new .prg functions:
HB_GTCREATE( <cGtName> ) -> <pGT>
HB_GTSELECT( <pGT> ) -> <pPrevGT>
Using this functions is possible to create many console window
if GT supports such possibilities (f.e. GTXWC or GTWVT) even in
single thread programs and switch between them.
* harbour/source/rtl/box.c
! fixed one of recent DISPBOX() modifications - it should use:
hb_gtBoxEx() instead of hb_gtDrawBox() to set cursor position.
+ harbour/tests/gtwin.prg
+ added demonstration/test code for using more then one console window
also in single thread programs.
* harbour/include/hbstack.h
* harbour/include/hbgtcore.h
* harbour/include/hbthread.h
* harbour/include/hbapigt.h
* harbour/source/vm/estack.c
* harbour/source/vm/hvm.c
* harbour/source/vm/thread.c
* harbour/source/rtl/hbgtcore.c
+ added support for optional allocating independent console window by
each thread. By default new thread inherits console Window from
parent thread. But each thread can allocate its own console window
by calling hb_gtReload( <cGtName> ) function, f.e. by:
hb_gtReload( hb_gtVersion() )
If GT driver supports such functionality then new it will allocate
new console windows.
Each console window has reference counter which is increased when
new thread starts and decreased when hb_gtReload() is executed or
thread terminates. When counter reach zero give console window is
destroyed.
* harbour/source/rtl/gtwvt/gtwvt.c
! use SendNotifyMessage() instead of SendMessage() to not block
threads which inherited GT from parent thread. Why non of MS-Win
users reported this problem?
+ added reference counter to window class for multi GT support
+ harbour/tests/mt/mttest10.prg
+ added demonstration/test code for using independent console window
in different threads. It needs GT driver which supports such
functionality, f.e GTXWC in *nixes or GTWVT in MS-Windows
* harbour/tests/mt/mttest09.prg
! fixed typo in comment
* harbour/include/hbapigt.h
* harbour/source/rtl/console.c
* harbour/source/rtl/filesys.c
* use HB_STD{IN,OUT,ERR}_HANDLE macros instead of hard coded values
* harbour/include/hbgtcore.h
* harbour/source/rtl/hbgtcore.c
* harbour/source/rtl/gtapi.c
+ added optional support for dynamic supertables
+ added reference counter to HB_GT_BASE structure
- removed hb_gtUnLoad() function
+ added hb_gtAlloc(), hb_gtRelease(), hb_gtAttach()
+ added hb_gtRealod() function which unloads current GT driver
and loads given new one
+ added .prg function HB_GTRELOAD( <cGtName> ) -> <lSuccess>
This function allow to switch active GT driver at run time.
It can be also used to simulate removed HB_NOSTARTUPWINDOW()
functionality. F.e.:
REQUEST HB_GT_WVT
REQUEST HB_GT_NUL_DEFAULT
proc main()
// do some initializations...
hb_gtReload( "WVT" )
// rest of code...
return
Please remember that some GTs may refuse initialization due to
missing required resources and instead of return FALSE they can
interrupt program with internal error, just like at application
startup so it's not guarantied that this function always returns.
* harbour/contrib/hbct/ctwin.c
* updated for new GT API
+ added support for dynamic supertable to allow using CTWIN in the
same time with different GTs.
* harbour/contrib/xhb/hbcompat.h
- removed hb_retclenAdoptRaw translation
* include/hbapi.h
* source/common/hbgete.c
+ Added hb_getenv_buffer(). Similar to hb_getenv() but
this one needs a buffer+size to be passed, so no memory
allocation is done by the function. It also return
a BOOL to signal success. It doesn't signal if passed
buffer was too small to store the value.
* harbour/include/hbstack.h
* harbour/source/vm/estack.c
* harbour/source/vm/hvm.c
* harbour/source/debug/dbgentry.c
* harbour/source/debug/debugger.prg
* moved debugRequest flag and debugger internal structure
pointer to HVM stack
* allocate debugger internal structure dynamically in thread
thread local area when PCODE with debug information is executed
* changed STATIC s_oDebugger to THREAD STATIC
* send HB_DBG_VMQUIT after each thread termination when
debugger is activated
Now debugger can be used in MT programs and each thread can be
debugged separately (each has its own debuger). Please only
remember that thread sharing console window can overwrite other
threads debugger screen. There is also one limitation which I'll
try to remove later: only main thread debugger keeps information
about file wide STATIC names and line numbers with possible break
point places. This data should be shared between debuggers.
* harbour/include/hbapi.h
* harbour/source/vm/hvm.c
* harbour/source/vm/estack.c
* disabled all debugger related bindings and variables when
HB_NO_DEBUG macro is set
% moved s_fDebuging to HVM function stack frame to eliminate
saving/restoring this variable in each function/message call
Note: if you think it's good to block linking .prg code compiled
with -b (debugger support) with HVM compiled with HB_NO_DEBUG
then it's enough to disable whole hb_dbg_SetEntry() function
in hvm.c when HB_NO_DEBUG macro is set.
* harbour/source/rdd/wacore.c
; updated comments about xbase++ behavior in dbRelease()
* harbour/include/hbvm.h
* harbour/source/vm/hvm.c
* harbour/source/vm/dynlibhb.c
* harbour/source/vm/runner.c
! added MT protection for HB_LIBLOAD()/HB_LIBFREE() and
HB_HRBLOAD()/HB_HRBUNLOAD(). Please remember that you should
not use any external LoadLibrary() functions because they are
not protected for clean PCODE modules loading/unloading even
in ST mode. Using them can cause HVM internal structure corruption.
If we have such functions in contrib then they should be redirected
to our HVM ones.
There is still one problem in MT mode which has to be resolved yet.
When dynamic library containing PCODE using static variables
is loaded 1-st time then it will force resizing of internal array
with static variables. If in exactly the same moment some other
thread operates on static variable then it may cause corruption.
To resolve this problem we will have to divide continuous memory
block common for all modules where we store all static variables
into separated blocks bound with each PCODE module (symbol table).
* harbour/source/vm/dynlibhb.c
+ added support for DLL loading/unloading in OS2 builds.
Based on xHarbour code by Maurilio Longo - please test.
* harbour/source/vm/thread.c
+ added small description for hb_threadOnce() .prg function
* harbour/include/hbthread.h
! do not set TLS in POCC and XCC builds when _MSC_VER macro is set
This compilers also have this macro but dllspec( thread) does
not work for them (at least in version 4.50.15)
* harbour/utils/hbtest/rt_hvm.prg
+ added few tests which exploit by DMC bug. Be careful with
this compiler. In some cases it gives buggy final code, f.e.
try this:
#include <stdio.h>
typedef struct
{
double dd;
long long int ll;
} UN;
const char * cmp( UN * pU )
{
return pU->dd >= pU->ll ? "OK" : "ERRROR";
}
int main( void )
{
UN u = { 10.50, 10 };
printf( "%s\n", cmp( &u ) );
return 0;
}
The same bug can be exploited also by final Harbour binaries
compiled by DMC in code like:
? iif( 10.50 >= 10, "OK", "ERROR" )
I used DMC 8.42n. As long as such things will not be fixed by
DMC developers this compiler is not supported by Harbour and
reported problems with DMC Harbour builds will have to be
ignored by us.
* harbour/include/hbclass.ch
* harbour/source/vm/classes.c
* harbour/source/rtl/tobject.prg
* harbour/source/rtl/tclass.prg

identical classes but with different handles were created
and registered in HVM
* harbour/contrib/xhb/xhbcomp.prg
* updated hack with optional inheritance for new class code
* make_b32.mak
* make_vc.mak

! Minor formatting.
* include/hbapierr.h
! Fixed casting in macro HB_ERR_FUNCNAME, as it was
generating a new warning with MSVC in 64-bit mode.
'( ( char * ) 1 )' -> '( ( const char * ) NULL + 1 )'
('const' keyword was not enough to silence it)
* include/hbapierr.h
* source/rtl/errorapi.c
- Disabled (marked with HB_LEGACY_LEVEL) hb_errFuncName

number (index in some GTs) instead of color string
* use int as color number (index) in hb_gtScrollEx() hb_gtBoxEx()
* harbour/source/rtl/box.c
% changed DISPBOX() with color and frame string to work as one
GT atomic operation
* harbour/source/vm/classes.c

; NOTE: Found yet another hidden extension in Alert() code :(
* source/rtl/radiobtn.prg
! Fix and optimization in recent modification.
* harbour/include/hbapigt.h
* harbour/source/rtl/gtapi.c
+ added C functions hb_gtLock() and hb_gtUnlock()
They block current GT for other threads
* harbour/source/rtl/gtfunc.c
+ added PRG functions hb_gtLock() and hb_gtUnlock()
They block current GT for other threads - be careful using them
and always unlock locked GT
* harbour/source/rtl/scroll.c
+ added HB_SCROLL() function - it works like SCROLL() but supports
2 additional parameters: color and erase char. It's stateless and
atomic in GT access
* harbour/source/rtl/tbrowse.prg
* use HB_SCROLL() instead of SCROLL(). Now whole TBROWSE class
does not depend on other thread screen output and does not
set any GT variables except of cursor positioning to active
cell when it's enabled
* harbour/source/rtl/memoedit.prg
* harbour/source/rtl/tgetlist.prg

* use atomic stateless functions when possible - this code should
be checked and updated by some who know it.
* harbour/include/hbapigt.h
* harbour/source/rtl/gtapi.c
+ added hb_gtDrawBox() works like hb_gtBox() but does not change cursor
posiion and support colors
+ added support for color parameter to hb_gtPutText()
* harbour/source/rtl/console.c
* use new hb_gtPutText() format in HB_DISPOUTAT()
Now all screen operations inside this function is one atomic
operation for other threads
* harbour/source/rtl/box.c
+ added HB_DISPBOX() function - works like DISPBOX() bit does not
change cursor position and is atomic for other threads

* harbour/include/hbvm.h
* harbour/source/vm/hvm.c
+ added hb_vmProcessDynLibSymbols() which works like
hb_vmProcessSymbolsEx() but always mark registered modules as
dynamic
* harbour/source/vm/maindllp.c
* redirect hb_vmProcessSymbolsEx() to hb_vmProcessDynLibSymbols()

* disabled some low level locking code in non MT HVM mode
* harbour/include/hbgtcore.h
* harbour/source/rtl/hbgtcore.c
* harbour/source/rtl/gtapi.c
+ added new GT methods: LOCK() and UNLOCK()
* serialize GT access in MT mode - please remember that it's only
low level serialization to protect access to low GT resources.
It has nothing to application level screen output from different
threads which has to be serialized by programmer if necessary.
* harbour/source/rtl/tthreadx.prg
* use HB_THREAD_INHERIT_PUBLIC as thread attribute for thread
started by oThread:start() to emulate xbase++ PUBLIC variables
behavior
* harbour/include/hbapigt.h
* harbour/source/rtl/gtapi.c
+ added hb_gtPutText() C function
* harbour/source/rtl/console.c
+ added HB_DISPOUTAT() which works like DISPOUTAT but does not change
cursor position. xBase++ users can use
#xtranslate DispOutAt( <x,...> ) => hb_dispOutAt( <x> )
for xBase++ compatible code
* include/hbextern.ch
+ Added missing HB_DISABLEWAITLOCKS().
; NOTE: This looks like a hack to add FLX_WAIT flag
for locks app-wide, and on Windows systems only.
IMO we should not have such hacks in core, or if
this is really important it should support all
possible platforms.
It also has a low-level function equivalent,
which is missing from hbapifs.h. There is no
reference to these function in any Harbour or
xhb changelogs.
If there are no objections, I'd like remove
this functionality.
* source/rtl/hbrandom.c

[TOMERGE 1.0]
* harbour/include/hbthread.h
* harbour/source/vm/hvm.c
* harbour/source/vm/thread.c
+ added .prg function
hb_threadWait( <pThID> | <apThID>, [ <nTimeOut> ] [, <lAll> ] )
=> <nThInd> | <nThCount> | 0
This function wait for <nTimeOut> seconds (default infinite wait)
until one or all (controlled by <lAll> parameter) of given HVM threads
will have finished execution in HVM area. It does not join the threads.
It returns index to 1-st thread which has finished execution (default)
or number of threads which has finished in given time period when lAll
is .T.
* harbour/include/hbstack.h
* harbour/source/vm/estack.c
* harbour/source/vm/hvm.c
% moved static USHORT uiPolls to HVM stack to not reduce the HVM
performance in MT mode. In multi CPU environment if many threads
try to change the same memory variable in the same time the overall
performance is strongly reduced on most of tested hardware - probably
some random CPU delay used to resolve the conflict.
* include/hbapierr.h
* source/vm/extrap.c
* source/rtl/errorint.c
! Fixed recent modification on Windows platform, where
GPF would generate an internal error.
It didn't launch the OS error handler.
! Fixed hb_errInternal() being marked as HB_EXPORT
in the headers only.
* include/hbextern.ch
* source/rtl/inkey.c
+ Added HB_KEYCLEAR() a documented function equivalent
to "CLEAR TYPEAHEAD" command, or undocumented __KEYBOARD() function.
* contrib/rddads/rddads.h
* contrib/rddads/ads1.c
+ Added support for ADS_USE_OEM_TRANSLATION for old ads versions.
Borrowed from xhb/Pavel Tsarenko.
