! Fixed old int <-> USHORT conversion MSVC warnings.
; TOFIX: ? There is a disagreement between different APIs
and Harbour program parts on the size and type of
number of parameters, it can be int, USHORT, ULONG,
and in some places there is also BYTE limit.
* source/common/hbver.c
* Minor formatting.
* source/vm/fm.c
! Fixed bcc C++ build errors by enabling USE_DL_PREFIX in this case.
Only this warning remain:
Warning W8008 ../../fm.c 386: Condition is always true in function dlmalloc_destroy()
* harbour/include/hbexpra.c
% reduce macro expressions used in POP operation.
It allows to use code like: &("((M->VAR))") := 1
* harbour/include/hbexprb.c
+ added support for iif() used in macro expressions passed by references:
proc MAIN()
local s := "IIF( lVar, xVar1, xVar2 )"
M->xVar1 := 1
M->xVar2 := 2
M->lVar := .T.
? M->xVar1, M->xVar2
P( @&s )
? M->xVar1, M->xVar2

* harbour/source/rtl/filesys.c
+ implemented OS independent task switching system - it gives PTHREAD
compatible basic API so it can be used in HVM as alternative MT support
which does not use any OS threads. As long as Harbour does not call
any blocking OS function then it's possible to create and execute
simultaneously many threads though only one CPU is used and switched
between HVM threads. It gives similar scalability to xbase++ threads
and also similar behavior in item protection at .prg level.
Now it's possible to use HVM threads in any OS.
Of course it does not mean that Harbour adds in some magic way
thread support to OS-es which does not support threads like DOS.
It only means that HVM supports threads for .prg code just like
in native MT environment as long as some C code does not block
task switching or process execution will not be frozen by sth, i.e.
executing other process (__run()) in single process OS like DOS.
In some cases it can be interesting alternative even in OS which
have native thread support.
All tests/mttest*.prg programs and speedtst --thread=<n> --scale
are executed correctly with new task switching just like with
OS native MT support.
Compilation with task switching in hbvmmt library can be forced
by HB_TASK_THREAD macro which also disable native OS threads
support.
For task context switching two alternative methods are used:
1) getcontext()/makecontext()/swapcontext() (SUSv2, POSIX.1-2001)
which is preferable because does not need any additional
hacks but not all OS-es supports these functions.
It's enabled by default in Linux builds.
2) setjmp()/longjmp() (POSIX, ISO 9899 (C99)) otherwise.
These functions are supported by most of C compilers
but there is no function to set new stack in saved context
so it's necessary to introduce for each architecure/C compiler
peace of code which makes it. Macro HB_TASK_STACK_INIT() in
task.c makes it. I defined this macro for x86@32 in DJGPP
Linux GCC and OpenWatcom builds. I tested OpenWatcom builds only
in DOS and Linux but probably it works in all x86@32 builds.
If someone is interesting in adding support for some other
platforms which does not support ucontext.h and 1-st methods
then please define above macro for them.
Have a fun with new toy ;-)
* harbour/source/vm/Makefile
* enabled hbvmmt in DJGPP and OpenWatcom DOS builds. It works well.
Viktor if possible please add support for -mt switch in hbmk2
in all builds even if we do not compile hbvmmt by default so
it can be used with DJGPP and OW and any other builds for which
someone enable hbtask.c though OS does not support threads.

It resolves the problem with Clipper compatibility (thanks to Alex
for information and example) in code like:
m->var := {0}
&("var[1]") += 10
and also many other things, f.e. now Harbour can cleanly compile
and execute this code:
proc main
local s
m->o := errorNew()
s:="o:tries"
? m->o:tries
? &s
? &(s+"+=2")
? m->o:tries
? &(s+":=3")

* INSTALL
* make_gnu.bat
+ Added support for Cygwin builds (passes call to make_gnu.sh).
+ Added Cygwin build starter example.
+ Cygwin mentioned as a requirement for mingwarm builds,
also added to PATH.
! Fixed cygwin autodetection.
! Fixed wrong PATH order in 'MinGW GCC + MSYS' example.
* Merged mingw+msys and cygwin bash based build methods,
and titled as "alternate" method.
Now all supported compilers work by starting up make_gnu.bat.
* utils/hbmk2/hbmk2.prg
! Change compiler autodetection to work for cygwin.
* mpkg_dos.bat
* mpkg_win.bat
* make_gnu.bat
! Fixed build process to work in paths containing spaces.
I didn't test the batch in pure DOS, so I may have broken it.
* config/win/install.cf
* config/wce/install.cf
! Fixed 'install' to work when there is a space in install path.
* make_gnu.bat
* INSTALL
+ Added support for HB_BUILD_LOG envvar. If set to 'yes',
it will automatically set log output filename to:
'log-<arch>-<comp>.txt'
if set to 'no' it will no make any extra redirection,
if set to any other value, it will be used for output
(both std and err). The batch will set HB_BUILD_LOGFILE
to the filename used for output for processing.
This feature requires Windows NT or upper host.
I didn't enable this feature yet by default to not break
existing user setups, but maybe I'll do it before the
final release.
* Modified text shown (+ beep thrown) when build failed.
* Messages now all start with 'Harbour'.
* Do not do the second build pass if the first one failed.

! Fixed CreateObject() not working due to typo.
Thanks to Itamar Lins for the report.
* mpkg_dos.bat
* mpkg_win.bat
* mpkg_win.nsi
+ Enabled HB_BUILD_LOG=yes.
* Silenced copy, zip, makensis commands.
+ Added message about failed build process.
* Changed to use 'copy' instead of 'xcopy'
* Changed internals so now they don't require HB_COMPILER
and HB_ARCHITECTURE to be set. This means that now
we can rely on autodetection even for mpkg_*.bat files.
Creating an installer is very easy now for most cases.
Just type:
mpkg_gnu.bat
* source/vm/set.c
+ Added file commit support to __MVSAVE(), if Set( _SET_HARDCOMMIT )

To adapt you code to this, please do changes below:
1) hb_itemPutCPtr() (with three parameters) -> hb_itemPutCLPtr()
2) hb_itemPutCPtr2() -> hb_itemPutCPtr()
Unmodified code will generate compile time errors, so it's easy
to spot where the modifications need to be done. For most users,
only case 1) will need to be dealt with.

* contrib/gtwvg/wvgsink.c
! Fixed BCC warning after recent change.
(BTW, does anyone know a switch to enable such warning:
"'x' is assigned a value that is never used" with *MinGW* ?
It's annoying that BCC catches it, while other compilers
don't. I'm now only using BCC when creating builds.)

; Please review maybe there is a lighter patch to achieve this
goal. I had to add NULL versions for two functions downstream.

Thanks to Xavi.
Please make any required correction, I didn't do tests with it.
* utils/hbmk2/hbmk2.prg
+ Added support for linux/icc compiler. (untested)
; Tested win/icc support (static exe, shared exe, lib, dll).
It worked, except that in shared mode it will display this,
when the MinGW built .dll is used (instead of its own):
Unrecoverable error 9012: Can't locate the starting procedure: 'MAIN'
* source/vm/extend.c
* Minor formatting.
* source/rtl/mlcfunc.c
! Fixed warning in HB_C52_STRICT mode.
* contrib/hbxbp/xbp.ch
! Fixed HB_OUTDEBUG() macro to work also in codeblocks when
not in debug mode, and also to better handle the case when
parameter is a variable.
* ChangeLog
+ Added incompat NOTE to hb_par*/hb_stor*() change.
* harbour/include/hbapi.h
* harbour/source/vm/extend.c
* renamed existing hb_par*() and hb_stor*() functions which supports
variable number of parameters (...) into hb_parv*() and hb_storv*()
* added new hb_par*() and hb_stor*() functions which use strict number
of parameters. New hb_par*() functions do not make hidden conversion
between types, f.e. hb_parl() returns 1 only for logical parameters
which contain .T.
* harbour/include/extend.api
* map Clipper _par*() functions to hb_parv*()

compatibility
* harbour/source/macro/macrolex.c
* replaced HB_LEX_IS*() macros by by HB_IS*() ones
* source/vm/fm.c
! Renamed s_fInited to s_fInitedFM to avoid collision
with similarly named variable in estack.c when using
HB_FM_STATISTICS and HB_HVM_ALL at the same time.
Thanks Xavi for the find.
* harbour/include/hbhrb.ch
* harbour/source/vm/runner.c
+ added support for HB_HRB_BIND_LAZY flag.
Lazy binding with public external functions allows to load .hrb files
with unresolved or cross function references.
- harbour/include/hbhrb.ch
+ harbour/include/hbhrb.ch
* replaced hbhrb.ch with slightly different version and set SVN
attributes:
svn:keywords : Author Date Id Revision
svn:eol-style : native
Now optional HB_HRBLOAD()/HB_HRBRUN() parameter is bitfield and
the following predefined values can be used to control function
bindings in loaded .hrb files:
HB_HRB_BIND_DEFAULT - do not overwrite any functions, ignore
public HRB functions if functions with
the same names already exist in HVM
HB_HRB_BIND_LOCAL - do not overwrite any functions
but keep local references, so
if module has public function FOO and
this function exists also in HVM
then the function in HRB is converted
to STATIC one
HB_HRB_BIND_OVERLOAD - overload all existing public functions
HB_HRB_BIND_FORCELOCAL - covert all public functions to
STATIC ones
Other HB_HRB_* defines will be added in the future
* harbour/include/hbvm.h
* declared hb_vmSetFunction() as internal function
* harbour/source/vm/hvm.c
* modified hb_vmSetFunction() to update references also in unused
modules.
* harbour/source/vm/runner.c
* removed CanUnload - it was not fully functional. Modules which
overloads public functions cen be unload just like any other ones
but unloading does not restore references to overloaded functions.
Now such references are simply lost and this should be fixed in the
future.
+ added support for HB_HRB_BIND_FORCELOCAL
! fixed <nOptions> parameter decoding in HB_HRBLOAD() to strictly
follow declaration:
HB_HRBLOAD( [ <nOptions>, ] <cHrb> [, <xparams,...> ] )
! fixed init procedures parameters in HB_HRBLOAD() to no pass <nOptions>
+ added support for <nOptions> to HB_HRBRUN()
HB_HRBRUN( [ <nOptions>, ] <cHrb> [, <xparams,...> ] ) -> <retVal>
* changed HB_HRBRUN() return value - now it's the result of executed
function instead of .T.
! fixed public symbol updating to keep valid references to HB_FS_LOCAL
function
! fixed possible memory leak
% added const to some char * declarations
TOFIX/TODO: add support for restoring overloaded functions when module
is unloaded.
* tests/testhrb.prg
* tests/Makefile
* include/Makefile
* include/hbhrb.ch
* source/vm/runner.c
! Added new files to Makefiles.
! Fixed to use hbhrb.ch from .c rather than replicating #defines.
(also fixed comments to be ANSI)
! Added self protection to .ch.
! Made .hrb file lowercase in testhrb.prg
! Deleted double license header from .ch.
* utils/hbmk2/hbmk2.prg
+ Added logic to move embedded compilers under a common subdir.
To stay compatible with 2.0.0beta1 release I didn't yet set
this, but it will be for final release.
Probably 'comp', or maybe 'opt'. Sorry for asking for opininons,
but they're welcome anyway.
* vm/runner.c
FIXED ;
../../runner.c:413: error: '_HB_SYMB' undeclared (first use in this function)
+ include/hbhrb.ch: HB_HRBLOAD() mode #define new file
+ tests/testhrb.prg: test program fro new params
+ tests/exthrb.prg: test program to be compiled as .HRB using /gh option
* source/vm/runner.c
* Formatted.
; TOFIX:
../../runner.c: In function 'hb_hrbLoad':
../../runner.c:413: error: '_HB_SYMB' undeclared (first use in this function)
../../runner.c:413: error: (Each undeclared identifier is reported only once
../../runner.c:413: error: for each function it appears in.)
* utils/hbmk2/hbmk2.prg
+ Added preliminary support for autosetup for several more
compilers: win/watcom, win/pocc, win/pocc64, wce/poccarm,
dos/djgpp, dos/watcom.
Only these were tested: dos/djgpp, win/watcom, win/pocc.
This means it's now possible to "bundle" DJGPP, watcom or
pocc _compiler tools_ with Harbour and hbmk2 will be able
to detect them, or user can choose between them using
-arch/-comp switches, then hbmk2 will just be able to use
them "as is", without the need to change anything on the
environment. zero-conf usage in essence, just like we
already had for mingw family.
; NOTE: Before the release I'll rethink placement of these
tools inside the Harbour directory tree. Currently
they are detected in the Harbour root dir, but with
multiple compilers this is not ideal.
* source/vm/thread.c
! Fixed compile error after 2009-06-16 08:55 UTC+0200.
* include/hbextern.ch
* source/vm/thread.c
+ Added HB_MUTEXWAITERSCOUNT() to core.
(slightly rewritten using local functions)
- examples/uhttpd2/umutex.c
- No longer needed.
* harbour/source/vm/mainstd.c
* forced '\' in argv[0] instead of '/' in DJGPP builds
* disabled using SHELL envvar and forced COMSPEC in system() function
in DJGPP builds (it effects __run() and hb_run() .prg functions)
* harbour/contrib/gtwvg/wvgwin.c
! fixed wrongly used & operator
* harbour/source/rtl/hbproces.c
* added TODO warning in OpenWatcom Linux builds
* harbour/make_gnu.sh
! fixed test_param() function definition - it has to be defined it's
before use
* harbour/include/hbexpra.c
* harbour/include/hbexprb.c
* harbour/source/common/expropt1.c
* harbour/source/rtl/round.c
* removed unnecessary <math.h>
* harbour/source/vm/hvm.c
* harbour/source/common/expropt2.c
* harbour/contrib/hbct/ctmath.h
* harbour/contrib/hbclipsm/num.c
* harbour/contrib/hbclipsm/numfloor.c
* harbour/contrib/hbclipsm/numceil.c
* use "hbmath.h" instead of <math.h> to avoid possible desynchronization
between used math libraries and header files
* harbour/source/pp/Makefile
! fixed real DOS compilation - replaced Windows only hack by wildcard
function usage
* harbour/config/dos/dir.cf
* removed intermediate sh call from executed commands
* harbour/source/vm/Makefile
* disabled HB_HVM_ALL in all Watcom builds - it works but the compilation
time is very huge so user who wants to use it should set envvar
HB_HVM_ALL=yes
* enabled HB_HVM_ALL for DJGPP builds
* include/hbextern.ch
* source/vm/hashfunc.c
+ Added HB_HGETDEF( <hHash>, <xKey>[, <xDefault> ] ) -> <value>
This function will return <xDefault> when <xKey> isn't
found in the hash table. If <xDefault> isn't passed, it
will return NIL.
* source/rtl/achoice.prg
! Partially reverted this commit:
https://sourceforge.net/apps/trac/harbour-project/changeset/10605
After this change, activating DBU menus with all items disabled
(f.e. F7/F8) caused app hang.
This line:
nUserFunc := iif( nMode != AC_NOITEM,;
Do( xUserFunc, nMode, nPos, nPos - nAtTop ), NIL )
Was now changed back to this:
nUserFunc := Do( xUserFunc, nMode, nPos, nPos - nAtTop )
ac_test2.prg still seem to function fine after this, but
I'd kindly like to ask Vladislav Lavrecky to make tests
again, maybe we need another fix here.
* source/vm/evalhb.c
* Minor formatting.
* contrib/hbtip/client.prg
* Minor formatting.
! :ReadToFile() nMode param check.
* utils/hbmk2/hbmk2.prg
* Cleanup to variable name prefixes.
* contrib/xhb/Makefile
+ contrib/xhb/xthrow.prg
+ Added THROW() function for xhb compatibility.
This is written in Harbour, based on hbcompat.ch
and has Harbour license + exception.
+ contrib/xhb/xcstr.prg
+ contrib/xhb/xdbmodst.prg
* contrib/xhb/Makefile
+ Ported following old functions from xhb:
CSTRTOVAL(), STRINGTOLITERAL(), VALTOPRG(), PRGEXPTOVAL()
+ Ported following new functions from xhb:
VALTOARRAY(), VALTODATE(), VALTOHASH(), VALTOLOGICAL()
VALTONUMBER(), VALTOARRAY(), VALTOTYPE(),
DBMODIFYSTRUCTURE(), DBIMPORT(), DBMERGE()
