* source/debug/tbrwtext.prg
* Replaced with new implementation from Lorenzo Fiorini.
Sent to the list on 2008.07.26.
; NOTE: Some issue were reported with this, but it's again
a step into the right direction, please try to update
this code to better resemble to Clipper and to fix
possible error. Thanks.
; Remaining RTL .prg dependencies:
- ACHOICE() (just one call)
* source/debug/debugger.prg
* Using hb_MemoWrit() instead of MemoWrit()
* source/rtl/achoice.prg
% Minor opt.
* harbour/include/hbclass.ch
* harbour/source/vm/classes.c
* harbour/source/rtl/tobject.prg
* harbour/source/rtl/tclass.prg
! fixed race condition when class function is called 1-st time
and new class is created. It was possible that more then one
thread execute this function simultaneously and two classes
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
* source/rtl/teditor.prg
+ Added :LineCount(), :ExitState() methods.
* Changed to use hb_MemoWrit() to write text content to
disk, to avoid Chr(26) to be appended.
! Fixed :InsertState() to also modify physical cursor state.
! Fixed :BrowseText() to not go into an infinite loop in
view mode.
* source/rtl/memofile.c
! Minor formatting.
* ChangeLog
! Fixed yesterday's entry dates.
* make_b32.mak
* make_vc.mak
* make_gcc.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
symbol. No longer supported, pls use HB_ERR_FUNCNAME
instead.
* harbour/include/hbthread.h
* casting cleanup
* harbour/include/hbapigt.h
* harbour/source/rtl/gtapi.c
* harbour/source/rtl/scroll.c
* harbour/source/rtl/console.c
* harbour/source/rtl/box.c
* changed hb_gtDrawBox() and hb_gtPutText() to operate on color
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
! fixed profiler usage
* harbour/source/rtl/tget.prg
! fixed cursor positioning when new get item is added.
; added note about possible modification - Viktor, please verify it
* harbour/source/common/expropt2.c
* formatting and minor cleanup
* harbour/source/rtl/gtapi.c
% do not set and restore default color set in hb_gtPutText() and
hb_gtDrawBox() but decode colors from passed string
* include/hbextern.ch
+ New functions added.
* source/rtl/alert.prg
% Minor optimization.
; 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
* harbour/source/rtl/tlabel.prg
* harbour/source/rtl/listbox.prg
* harbour/source/rtl/tmenusys.prg
* harbour/source/rtl/achoice.prg
* harbour/source/rtl/profiler.prg
* harbour/source/rtl/teditor.prg
* use atomic stateless functions when possible - this code should
be checked and updated by some who know it.
* harbour/source/rtl/scrollbr.prg
* harbour/source/rtl/getsys.prg
* harbour/source/rtl/tpopup.prg
* harbour/source/rtl/tgetlist.prg

* harbour/source/rtl/achoice.prg
* harbour/source/rtl/teditor.prg
* harbour/source/rtl/radiobtn.prg
* harbour/source/rtl/tbrowse.prg
* replaced DispOut() with hb_dispOut()
* replaced DispBox() with hb_dispBox()
% removed saving and restoring of cursor position in places where
it's not longer necessary due to hb_dispOut()/hb_dispBox() usage
% removed saving and restoring of SetColor() value in places where
it's not longer necessary due to hb_dispOut()/hb_dispBox() usage
% removed saving and restoring of MSetCursor(). If it's necessary
low GT driver should hide and redraw mouse cursor before and after
screen update. We do not have to make it manually
The above modification gives faster code and allow to access screen
from different threads simultaneously because functions like
hb_dispOut() and hb_dispBox() are stateless and atomic in screen
access. Not all .prg code has been updated yet. If someone is
familiar with this code then please help. I'll add yet HB_SCROLL()
function which will support additionally colors.
Viktor if possible please verify this modifications.
* 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/hbapigt.h

* harbour/contrib/gtwvg/gtwvg.c
* cleanup char * casting
* harbour/source/rtl/filesys.c
! do not use pread()/pwrite() in OpenWatcom Linux builds
* harbour/source/vm/hvm.c
* reduced the mutex lock time in thread exit state
* harbour/source/vm/thread.c
; added note about possible behavior of hb_threadSelf() function
in one very specific situation. It's documented and expected
behavior
* harbour/source/rtl/hbgtcore.c
+ added support for retrieving current HB_GTI_NOTIFIERBLOCK code block
+ added support for removing HB_GTI_NOTIFIERBLOCK code block without
setting the new one
* harbour/source/vm/garbage.c
* unblock HVM before executing destructors and releasing blocks
* harbour/source/vm/fm.c
! do not call internal error with active lock when FM statistic
is enabled
* harbour/source/vm/thread.c
! stop other threads in hb_threadOnce() if the 1-st one
executes bAction block to be sure that it will be completed
before thread leave hb_threadOnce() function
* harbour/source/vm/set.c
! do not call hb_inkeyReset() in set release. It's not necessary
and it could change keyboard buffer size for other threads using
the same GT driver.
* harbour/source/vm/hvm.c
% allocate new thread stack without lock
* harbour/source/rtl/hbgtcore.c
* harbour/source/rtl/gtapi.c
* moved clipboard resetting from hbgtcore.c to gtapi.c
* harbour/source/rtl/filesys.c
! do not use read/write operations with given file offset in Win9X
which seems to not support such functionality
* 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
* harbour/common.mak
* harbour/source/rtl/Makefile
+ added thfuncx.prg
* harbour/source/rtl/thfuncx.prg
+ added ThreadObject() function
* harbour/source/rtl/tthreadx.prg
+ added xBase++ compatible TThread class.
Special thanks to Pritpal Bedi for class skeleton with info about
xbase++.
Now only basic functionality is supported though it was enough to
compile and execute examples Pritpal sent. I'm leaving rest for
xBase++ users.
BTW The examples suggest that in xbase++ DispOutAt() does not change
cursor position. It's not Clipper compatible so I cannot make it
in Harbour though I can add new function which will work in such way.
* 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
* source/rtl/filesys.c
* Minor formatting.
* bin/bld.bat
* bin/bld_os2.cmd
+ Added support for HB_INSTALL_PREFIX.
+ Added experimental support for 'set HB_MT=MT' flag,
to create an MT executable.
* source/rtl/seconds.c
* Formatting.
* harbour/source/rtl/seconds.c
+ Added OS/2 section to secondsCPU(), but it does not work as expected :)
In particular, user and system times are kept per thread, but when a thread
dies the time it has spent in user and system-land gets lost, so the
overall running time of the program decreases. Not only, if I call
secondsCPU() before a thread starts and after it has ended I'll have
no idea of the time that was spent by that thread.
* 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.
* harbour/source/vm/hvm.c
! fixed last commit typo in thread number allocating - all threads
where using 0 number
* harbour/source/vm/thread.c
! fixed return value in recursive call to hb_mutexLock() - was FALSE
! fixed typo in timeout parameter number
should be 2 instead of 1
* harbour/source/rtl/tobject.prg
! fixed init() return value - it should be ignored and current
object should be returned
* harbour/source/rtl/tthreadx.prg
! probably fixed timeout parameter use in signal:wait() method
I guess that like other xbase++ functions it's in 1/100th of
a second
* harbour/include/hboo.ch
* harbour/include/hbclass.ch
* harbour/source/vm/classes.c
* harbour/source/rtl/tclass.prg
+ added support for SYNC object and CLASS messages working like
in xBase++. Please remember that all locked by thread SYNC messages
objects and classes are unblocked automatically for the time which
thread spends in hb_subscribe[Now]() or signal:wait()
* include/hbapifs.h
* include/hbextern.ch
* source/common/hbfsapi.c
* source/rtl/hbfile.c
+ Added hb_fsNameExists() C level function.
+ Added hb_FNameExists() Harbour level function.
; Both will return true if any kind of directory entry
exists with the given name (IOW it doesn't matter
if it's a file or directory, or else).
* harbour/tests/speedtst.prg
* marked T054 as memory tests
* harbour/source/vm/hvm.c
* harbour/source/vm/thread.c
* added hb_threadOnce( @<onceControl> [, <bAction> ] ) -> <lFirstCall>
This function allow to execute some code only once. It's usefull in
MT environment for initialization.
<onceControl> is variable which holds the execution status and have
to be initialized to NIL. In most of cases it will be simple static
variable in user code.
<bAction> is optional codeblock which is executed only once (on 1-st
call with given <onceControl>)
* harbour/source/rtl/filesys.c
! do not make any file name conversions in hb_fsNameConv() if HVM stack
is not allocated
* harbour/source/rtl/gtcrs/gtcrs.c
* casting
* source/debug/debugger.prg
* source/rtl/typefile.prg
* source/rtl/tgetlist.prg
* source/rtl/treport.prg
* source/rtl/teditor.prg
* Using [Q]QOut() functions instead of "[?]?" commands.
* Using hb_Run() function instead of RUN command.
* source/rtl/typefile.prg
% Upped read buffer.
* Formatting.
% Got rid of a few unnecessary initialization.
* source/vm/extrap.c
+ Now using standard internal error call for Windows too.
+ Implemented //BATCH for OS/2. (please test)
* source/rtl/errorint.c
* Upped internal buffer.
* contrib/hbole/oleauto.prg
* contrib/hbole/ole2.c
* contrib/hbwin/win_tole.prg
* contrib/hbwin/win_ole.c
* OLESHOWEXCEPTION() implemented on the .prg level, using
Alert() rather than MessageBox().
! All MessageBox()es converted to Alert()s.
+ Added OLEEXCEPTIONSOURCE(), OLEEXCEPTIONDESCRIPTION()
to hbole.
* source/vm/maindllp.c
! Changed MessageBox() call to internal error.
* contrib/gtwvg/gtwvg.c
* source/rtl/gtwvt/gtwvt.c
! Changed MessageBox() calls to internal error.
* contrib/gtwvg/gtwvg.c
* Internal error calls synced with GTWVT.
* source/rtl/hbgtcore.c
- Removed "Internal error" text from two internal error descriptions.
* make_vc.mak
- Removed reference to MessageBox() from comment.
; NOTE: No more MessageBox() calls in Harbour.
(except some wrappers for user .prg code)
