* include/hbdefs.h
! Fixed 64-bit printf() formatting strings to be compatible
with MinGW. MinGW seems to follow the Microsoft way instead
of being compatible with other GCC dialects.
This fixes some pcode/c code (-gc3) generation problems for
long long literals, and hbfbird/FBGETDATA() potential problems,
when MinGW 3.x/4.x compilers were used.
[TOMERGE 1.0]
; TOFIX: Some sqlite3.c code may also be affected, since
"%llX" and "%lld"s are hard-coded into the source.

* harbour/include/hbstack.h
* harbour/source/vm/estack.c
* moved from RTL to HVM
* eliminated hb_set global structure
* moved set structure to HVM stack
+ added internal function hb_setClone() which is used to create
copy of SET structure for child threads
* hidden HB_SET_STRUCT declaration - 3-rd part code must not access it
directly. Dedicated hb_set*() functions should be used instead.
+ added new function:
BOOL hb_setSetItem( HB_set_enum set_specifier, PHB_ITEM pItem )
which allow to change some set by 3-rd party code.
TODO: not all SETs can be changed yet - if someone have a while
then please add code for missing ones.
* harbour/include/set.ch
* harbour/include/hbset.h
+ added _SET_CODEPAGE which works like _SET_LANGUAGE giving common
interface
* harbour/include/hbsetup.h

* harbour/source/vm/hvm.c
! fixed builds which uses non EN lang or code page modules
by forcing linking the chosen ones
* harbour/include/hbstack.h
* harbour/source/vm/estack.c
* harbour/include/hbapicdp.h
* harbour/source/rtl/cdpapi.c
- removed global code page variable: hb_cdp_page and moved
code page settings to HVM stack

character ID
+ added new functions hb_vmCDP() and hb_vmSetCDP() to get/set
active for given thread code page structure

* harbour/source/vm/itemapi.c
* harbour/source/vm/memvars.c
* changed memvar handles for HB_HANDLE to void * which is directly
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
+ added internal functions hb_dynsymGetMemvar()/hb_dynsymSetMemvar()
+ added hb_memvarGetValueBySym() for debugger

* eliminated all static variables in memvars module
* harbour/include/hbstack.h
* harbour/source/vm/estack.c
* harbour/source/rtl/fserror.c

It allows to use hb_fs*() functions without allocated stack
by 3-rd party threads.
* harbour/source/rtl/filesys.c
* 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.
* harbour/source/rdd/wacore.c
* moved WA list, current WA, default RDD and neteer() flag to HVM stack
* harbour/include/hbdefs.h
- removed HB_HANDLE declaration
* harbour/include/hbapi.h
- removed HB_VALUE structure - it's not longer used due to different
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
* use TSD data for allocated keys to make SETKEY() thread independent
* harbour/source/rtl/math.c
* moved math error handler, math error block, math error mode and
math error structure to TSD

* moved error handler, error block, error launch counter and DOS error
value to TSD
* harbour/source/rtl/inkey.c

* harbour/source/rdd/hsx/hsx.c
* moved HSX handles array to TSD
* harbour/include/hbapigt.h

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

+ 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
* harbour/source/rtl/mouseapi.c
* harbour/contrib/hbct/ctwin.c
* free GT pointer by hb_gt_BaseFree()
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.

* harbour/source/vm/garbage.c
* changed to work with MT HVM
* changed to work with new memvar structures and thread local static and

* added MUEXT protection for linked block lists

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

+ 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.

; Old names are still working if HB_LEGACY_LEVEL

; It's highly recommended to change all 3rd party and
app C code to use the new #defines/types/functions.
; NOTE1: There are some more names which are still
in the legacy "namespace", and gradually
I'd like to clean some of these as well. The most
important would be the type names, as these
are currently colliding with multiple external
packages, like windows.h, and it also makes it
impossible to compile hbfimage on certain systems.
; NOTE2: I'd also like to move the *_PTR (like HB_ITEM_PTR)
names to legacy status as we don't really use
them except in a few VM files, and we have PHB_*
as a wide-spread (and shorter) replacement.
; NOTE3: We may also use HB_LEGACY_LEVEL to obolete other
legacy or unsafe functions, with better new
alternatives.
; NOTE4: Here's a more or less complete list of names
that _may_ cause such problems:
; Type related stuff
- TRUE, FALSE
- BOOL, BYTE, SCHAR, UINT, USHORT
- INT_MAX, INT_MIN
- INT16, INT16_MAX, INT16_MIN

- UINT24_MAX
- UINT32, UINT32_MAX
- UINT64, UINT64_MAX
- ULONG, ULONG_MAX
- ULONGLONG, ULONGLONG_MAX
- assert()
; Some hacks currently used:
- HB_DONT_DEFINE_BASIC_TYPES
- HB_DONT_DEFINE_BOOL
- HB_OS_WIN_32_USED ->
(include <windows.h> locally where needed)
; Compiler related stuff:
- VS_*, VU_*, VT_*, FUN_*
- *COMDECLARED, *COMCLASS, *COMSYMBOL

- _FUNC, PFUNCTION
- _INLINE, PINLINE
- _FUNCALL, PFUNCALL

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

download cegcc-mingw32ce-0.50-1.i586.rpm and install it.
The hb* scripts created by ./make_xcemgw.sh [tgz|gnu] are
automatically updated to work with CeGCC-MinGW32 so later you
can simply crate WinCE-ARM binaries using them as for native port.
I'm waiting for users feedback. Please remember that I'm not Windows
user and even this port was created without any Pocket machine.
With Marek Paliwoda help I only tested that final applications are
working using PocketPC emulator.

* harbour/include/hbdefs.h
+ added HB_IMPORT macro
* harbour/include/hbset.h
* declare hb_set with HB_IMPORT attribute when HB_SET_IMPORT macro is set
+ added macros to retrieve information from hb_set structure:
hb_setGetCPtr(), hb_setGetNI(), hb_setGetNL(), hb_setGetL()
In the future these macros will be replaced by functions and
direct access to hb_set structure from non core code will be
forbidden so please update your code and and replace all
hb_set.HB_SET_*
with
hb_setGet*( HB_SET_* )
f.e. replace:
hb_set.HB_SET_SOFTSEEK
with:
hb_setGetL( HB_SET_SOFTSEEK )
I'll also add hb_setPut*() functions to assign some set values.
Both hb_setGet*() and hb_setPut*() functions will validate parameters
and in future MT mode will operate on global or thread local structures.
* harbour/contrib/rdd_ads/ads1.c
* define HB_SET_IMPORT before #include "hbset.h"
* use hb_setGet*() to access SET values

* harbour/include/hbexprb.c
! fixed code generated for logical expressions when shortcutting
is enabled to be Clipper compatible
* harbour/source/compiler/cmdcheck.c
! added missing break in -z compiler switch decoding
* harbour/source/compiler/hbfix.c
% added optimizations for code generated for logical expressions,
it strips a chain of HB_P_DUPLICATE -> HB_P_JUMP[TRUFALES] ->
HB_P_DUPLICATE -> HB_P_JUMP[TRUFALES] -> ...
In fact it should not be done here but because we do not have
any metacode level where such optimizations should be done and
PCODE is generated online then it will have to be here. Maybe
in the future we will add metacode.
* harbour/source/rdd/dbcmd.c
* make "M" alias Clipper compatible. After some thoughts I decided
that in some cases it can be usable so now "M" will set WA number
to 65535 like in Clipper.
* harbour/source/rdd/dbf1.c

* harbour/source/vm/macro.c
* removed hb_compMemvarCheck() - this function was not dooing
anything - only slows the TYPE() by calling hb_dynsymFind()
one or two times.
+ added TODO note: memvars create by TYPE() have PUBLIC scope
in Clipper. Clipper also always tries to evaluate valid expressions
inside TYPE even if the contain UDF. UDF only stops evaluation
so:
TYPE( "(val:=1) + f() + (val2:=2)" )
creates in clipper public variable VAL but not VAL2.

Now left side expression is evaluated _ONLY_ once and when object
messages are used it's guarantied that exactly the same object
variable will be used. It also fixes some problems which exists
in Clipper. This optimization is enabled by -kh flag (by default)
and can be disabled with -kc.

+ New PP code written from scratch. It works in similar way to
Clipper PP even the error codes are replicated. The code is MT
safe does not have any limitation on size of preprocessed code,
line, etc. It's also Clipper compatible lexer. It means that
we do not longer need FLEX or SIMPLEX which can be replaced
by new PP after some small modifications. Anyhow I haven't
decided to make it myself. I would like to agree with with the
rest of developers. I will be very happy if such modifications
will be done by someone else, Ryszard?
Meanwhile I current PP join on output the line tokens and give
the string line to FLEX/SIMPLEX. It does not have any sense and
all FLEX/SIMPLEX limitations are still existing. Ryszard, even
if we keep it then I hope you can remove at least FLEX line buffer
and use the one returned from PP.
Because string tokens in parsed line are converted to text which is
later once again decoded to tokens by FLEX I had to introduce new
string format which supports embedded string delimiters. I chose
modified version of xHarbour extension with escaped strings e"<sting>"
so now FLEX understand such strings and decode them like C escaped
strings. It means that you can use them also in the .prg code f.e.:
outstd( e"Hello\n\rWorld" )
The new PP is also noticeable faster. You should see the difference
compiling long files. The build in PP rules are generated automatically
by ppgen program created from source/pp/ppgen.c
I had to add to GNU source/pp/Makefile these two lines:
pptable.c : ppgen$(EXE_EXT)
./ppgen$(EXE_EXT) $(TOP)$(ROOT)include/hbstdgen.ch -opptable.c -q
Sth like that will have to be done also in non GNU make system.
Now Harbour can be compiled only using GNU make.
Marek can you update non GNU make files? I would like to leave this
modification to you or other developers who can test it.
It was quite big modification and I do not believe that I haven't
make any mistakes but I hope that in few weeks I'll fix any reported
bugs and it will resolve any PP problems.
TODO:
* error messages
create one common list of errors and warnings and keep it
in common library. PP and compiler can still generate different
errors with the same number. It can be confusing for the users
and hard to document and add i18n translations.
If possible we should also try to keep Clipper error numbers.
In new PP code I added Clipper error numbers but I cannot use
them until compiler code is not updated.
We should aslo remove the ctype passed to error functions and
hack with first character in warning messages and use only
error number. The codes from 1000 to 1999 should be warnings
where range 1000:1099 is activated by -w, 1100:1199 by -w1,
1200:1299 by -w2, etc. 2000:2999 are errors and 3000:3999
fatal errors. All compiler functions which generate an error
should expect that error function will not stop the compiler
but return and cleanly finished their job. It's necessary for
MT support in compiler and making compiler part of some other
programs which may still work and compile different source code.
* FLEX/SIMPLEX
remove them at all and add some final pass to PP to create
more precise tokens for grammar parser or at least add better
integration to remove some redundant code and existing limits.
* hb_inLine() support - it's broken in new PP but as I can see
it was never working correctly. I can add a hack to PP to support
hb_inLine() but I'm not sure it's worth to do. Maybe in few days.
+ harbour/include/std.ch
+ added new std.ch. It was created without using Clipper's std.ch.
It's quite possible that some rules are wrong and should be fixed
so please help. Anyhow I created a set of programs based on new PP
code generating all possible combinations of different commands I
collected from different source code, documentation and match patterns
of rules I was adding to new std.ch and then I was comparing .ppo
files generated by Clipper and Harbour so I do not expect any bigger
problems then some minor typos. I had to introduce some modifications
in spacing as workaround for FLEX/SIMPLEX which cannot properly decode
text preprocessed by Clipper after stringify.
* harbour/utils/hbpptest/pretest.prg
* updated for new PP
It reports 16 wrong translations but some of them are valid
and some others are caused by escaped string e"..." (one of hack
for FLEX/SIMPLEX support)
I also had to remove all spaces in comparison the results
because they were not Clipper ocmpatible at all. Ryszard please
look at it.

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

hb_memvarValueBaseAddress(), hb_memvarGetVarHandle(),
hb_memvarGetValueByHandle(), hb_clsCreate(), hb_clsAdd(),
hb_clsAssociate(), hb_hashTableDel(), hb_hashTableSize(),
I haven't touched them yet though we will have to keep in mind that
we should make sth with them.

* harbour/include/hbdefs.h
* use extern "C" as default for HB_FUNC() declaration in C++ mode.
I know that this modification will interact with binary compatibility
but current state is worser because we were not binary compatible
between C and C++ mode. Now the problem should gone with some
reasonable for me cost. If your compiler uses the same ABI for C and
C++ mode then the backward binary compatibility problem can be resolved
by small tools which can strip C++ decoration from binary libraries or
maybe even linker has necessary switches to ignore them.
* harbour/include/hbexprb.c
* cleaned BCC warning
* harbour/source/rdd/nulsys/nulsys.c
+ added missing hb_rddGetAliasNumber(), thanks to Ron.

alignment
* removed counters from HB_CODEBLOCK and HB_BASEARRAY structure
+ added hb_xRefInc(), hb_xRefDec(), hb_xRefFree(), hb_xRefCount(),
hb_xRefResize() functions. They are internal Harbour VM functions
and covered by internal API macro. Should not be used by 3-rd
party code because we may change them in the future or even remove.
+ added hb_gcRefInc(), hb_gcRefDec(), hb_gcRefFree(), hb_gcRefCount()
functions. These are also internal function which corresponds to the
above hb_x*() ones.

necessary and it should never be public function - it was implemented
in very dangerous way.
- removed hb_codeblockDelete() function.
- removed hb_memvarValueDecGarbageRef()

so it does not break backward binary compatibility.
* changed symbol init macros to work correctly with modified address
of symbol table
* harbour/include/hbsetup.h

hb_vmEnumNext()/hb_vmEnumPrev() and remove max number of iteration
stored on HVM stack
* temporary use hb_itemUnRefOnce() instead of hb_itemUnRefRefer() as
workaround for possible GPF. I'd like Ryszard will chose the final
version

* harbour/include/hbdefs.h
* use i64 suffix for BCC 3.0 and higher for long long int
* harbour/source/rtl/dummy.prg
* harbour/source/rdd/dbcmd.c
* added undocumented Clipper function: __dbTrans()
__dbOpenSDF() and __dbJoin() I'll commit soon.
There is also __dbTransRec() in dummy.prg but I cannot find any
information about this function and its parameters in GOOGLE.
If someone knows what is this functions syntax and can Inform
me then I'll implement it. I guess it's a wrapper to TRANSREC()
RDD method.
* harbour/source/rdd/dbf1.c
* DBI_LOCKOFFSET now returns DBF record lock offset really used
(f.e. updated in FP locking after open/close production index)
* harbour/source/rdd/delim1.c
* cleaned BCC warning
* harbour/source/rdd/dbfcdx/dbfcdx1.c

* call AdsFlushFileBuffers() only when _SET_HARDCOMMIT is set (default)
* harbour/include/Makefile
+ harbour/include/hbgfx.ch
+ harbour/include/hbgfxdef.ch

* harbour/include/hbapigt.h
* harbour/include/hbgtcore.h
* harbour/source/rtl/gtapi.c
* harbour/source/rtl/hbgtcore.c
+ added hb_gtGfxPrimitive(), hb_gtGfxText() - it's a work in progress
now this functions works like in xHarbour allow to draw graphic
objects in GTs which can do that (GTALLEG, GTXWC) but I plan to
introduce some modifications in them.
+ harbour/tests/gfx.prg
+ added test program by Mauricio Abre (borrowed from xHarbour) which
illustrates GFX usage
* harbour/include/hbdefs.h
* harbour/source/compiler/genc.c
* harbour/source/compiler/harbour.c
* harbour/source/vm/hvm.c
* minor modification in some harbour func name and symbol scope
definitions - I'd like to keep them in one place for easier
manipulations in the future
* harbour/source/compiler/harbour.y
* harbour/source/pp/ppcore.c
* harbour/source/pp/pplib.c
* harbour/utils/hbpp/hbpp.c
* clean a little bit recent modification it should resolve the
problem with GPFs reported by users and some possible memory
leaks when preprocessing/compilation process is interrupted.
Ryszard I decided to always store copy of file name in open
files structure - it can be used by compiler, preprocessor,
PPLIB and HBPP and IMHO in all cases it should have valid
and always initialized in the same way members for easier
manipulation. In the future I'd like to clean the whole PP
usage. I will need to keep all compiler and PP static variables
in one structure pointed by pointer in thread local data or
passed to called functions for MT support.
* harbour/source/rtl/cdpapi.c
* set 0 at the end of destination string in hb_cdpStrnToUTF8()
* harbour/source/rtl/dateshb.c
! fixed possible GPF in CTOD when badly formated date is given
* harbour/source/rtl/gtxwc/gtxwc.c
* harbour/source/rtl/gtxwc/gtxwc.h
* changed the selection code - now both PRIMARY and CLIPBOARD
selections are set by Harbour. It should work with any programs
which uses any of them but I'd like to remove one of this selections
or give user a way to chose the preferred one. I can also add support
for automatic setting/clearing/pasting PRIMARY selection by GTXWC
with mouse and shift key. I'm waiting for opinions.
+ added basic support for GFX operations
+ harbour/source/rtl/gtalleg/Makefile
+ harbour/source/rtl/gtalleg/fixedth.sfc
+ harbour/source/rtl/gtalleg/gtalleg.c
+ harbour/source/rtl/gtalleg/ssf.c
+ harbour/source/rtl/gtalleg/ssf.h
+ added new GT by Mauricio Abre based on Allegro cross platform
graphic libraries.
Code borrowed from xHarbour and modified by my for new Harbour
GT API.

* harbour/include/Makefile

+ harbour/include/hbgtinfo.ch
+ added GTI_* defintions for hb_gtInfo() function.
This function works in similar way to dbInfo() in RDD.
The GTI_* definitions are taken from xHarbour "as is" and
they should be cleaned - not all functionality are supported
in Harbour and some others should be implemented in differ
way then in xHarbour.
+ harbour/include/hbgtcore.h
* harbour/include/hbapigt.h
* new GTAPI
hbgtcore.h file should not be included by user code
it's only for internal use in GT drivers
* HB_inkey_enum changed to int - this is bit field not enumerated type.
Many of C/C++ compilers forbid bit operations on enum types and
forcing it by casting which finally exceeds the enum range is defined
as bug because it may badly interacts with some compiler optimizations
* harbour/include/hbapi.h

* harbour/include/hbstack.h
* harbour/include/hbvm.h
* harbour/include/hbvmopt.h
* harbour/include/hbvmpub.h
* separated internal and external API. Now the definitions for
internal HVM structures and functions are excluded by default
they could be enabled if user include hbvmopt.h before other
header files. Such operation should be done _ONLY_ by core
code - if 3-rd party developers make sth like that then it's
for their own risk and such code may stop to work with next
Harbour versions. Without hbvmopt.h the internal structures
like HB_ITEM, HB_DYNS, ... are mapped to 'void' so there is
no way to access their members so we can modify them in the
future without afford for 3-rd party code.
There is one small exception 'type' should be the first member
for HB_ITEM structure because I used a small ugly hack in
HB_IS_*() macros with castin PHB_ITEM to HB_TYPE* - it works
without speed overhead but if you think that it will be
better/cleaner to not use such tricks then it's enough to
change HB_ITEM_TYPE() definitions in hbvmpub.h - see note.
* cleared the usage of HB_EXPORT - to avoid problems with some C/C++
compilers we agreed that the only one common way of using HB_EXPORT
is adding it ad begining of declaration - please keep this convention
in the future.
+ added new functions:
hb_extIsObject(), hb_codeblockId(), hb_idleSleep(),
hb_fsGetOsHandle(),
hb_dynsymFindSymbol(), hb_dynsymGetSymbol(),
hb_dynsymSymbol(), hb_dynsymName(),
hb_dynsymMemvarHandle(), hb_dynsymAreaHandle(), hb_dynsymSetAreaHandle()
* changed hb_arrayClone() declaration to:
PHB_ITEM hb_arrayClone( PHB_ITEM pArray )
* changed hb_arrayFromParams() declaration to:
PHB_ITEM hb_arrayFromParams( int iLevel )
The previous version needed a pointer to stack relocatable area
so any stack resizing could cause GPF.
* harbour/include/inkey.ch

% rewritten jump optimization
! fixed some minor problems
* do not optimize jumps and local variable access by shorter
PCODE version and HB_P_NOOP when jump optimization is
disabled, this is a note I left in source code in few places:
/*
* optimizing jumps here by shorting them and setting HB_P_NOOPs
* only slow down the compilation process for three reasons:
* 1. When it's dummy jump to next instruction we need two passes
* in hb_compOptimizeJumps() to fully remove it
* 2. hb_compOptimizeJumps() also make jump shortcutting in each pass
* 3. When Jump Optimization is disabled (-kJ) then it cause slowness
* at runtime because we will have more HVM loops: first for the
* shorter jump and next for the HB_P_NOOP PCODE(s)
* [druzuz]
*/
+ added support for multi passes in jump/dead code elimination
(hb_compOptimizeJumps())
By default is set upto three passes.
Now hb_compOptimizeJumps() keeps all compiler internal data clean
on exist and can be called any times and does not change other
compiler's functions behaviors
+ added dummy jumps elimination
+ added optimization for:
IF .T.
IF .F.
WHILE .T.
WHILE .F.
etc.
* restored empty BEGIN/RECOVER sequence block elimination
if Jump Optimization is enabled then it marks the block
with HB_P_NOOPS else it cut the generated PCODE
+ added dead code eliminator (new functions hb_compCodeTraceMarkDead()/
hb_compPCodeTrace() - it works only when Jump Optimization is
not disabled)
As a result of the above we have smaller and faster PCODE.
I do not think that we will have meta code support in the reasonable
time and because I need some valid compiler data/structures like
updated table of all jumps for real C code (not PCODE in .c files)
generation then I decide to make some modifications and the above
is in practice a side effect of this work.

Ryszard I've removed some of your extensions which are no longer

(utf-8/iso) at startup and switch the internal logic to
iso/unicode mode. When compiled with slang 1.4x or 2.x
and terminal is in UTF-8 it can display all characters like
in DOS if only used font have them or good fall-back table is

what broke GNU make compilation for some compilers
This libraries should be included automatically when RDD lib
is included by *.cf files
Summary:
The whole patch (cvs diff -uN) is ~1.5MB length and I cannot describe
everything in details - sorry but it was too much modifications in
one commit so now just some of general notes.
The header files included as is does not have any information about
internal HVM structures and some functions. In practice only HB_SYMB
is public and it has to be public for .c files generated from .prg
so I force the fixed size of this structure (alignment independent)
by redefining some members to union with void * - it's a little bit
ugly trick but it effectively eliminates the problem of linking
binaries compiled with differ alignment C compiler switches.
The structures like HB_ITEM, HB_CODEBLOCK, HB_STACK, HB_DYNS are not
longer defined and pointers to the defined as void * - like in Clipper
the ITEM structure. It caused that I had to add some new functions
to make some operation still possible to implement. If I missed sth
and any of you will have a problem with your code then please inform
me about it and after a small discussion on Harbour developers list
we can decide if other functions should be added.
The internal API is still accessible. It's enough to include "hbvmopt.h"
file before other header files to enable it. Now only files in
source/vm directory include it.
The 3-rd party code which does not include hbvmopt.h (or tries to
set some internals macros) should be safe for future HVM modifications
and will work also with new binaries so 3-rd party library developers
should remember about it. If they won't then it's only their and
their clients problem not Harbour developers.
With this modifications I also create new GT model which is similar
to the one used by RDD with multi inheritance. It can be quite easy
extended to simultaneously load more then one GT subsystem (sth like
work areas in RDD) but I left it for the future when someone may
need it. hbapigt.h file now contains only information about public
functions and does not have any code which depends on current
internal implementation - it should be backword compatible as long
as somone did not try to use internal GT functions.
The internal GT system use hbgtcore.h file which should not be
included by 3-rd party code as long as someone will not make new
GT driver. The internal GT code is new so I expect that it will
be changed yet in the nearest future (I'm waiting for other developers
feedback) and in such case any 3-rd party GTs will have to be updated.
How it works:
The base GT driver (GTNUL) is fully functional GT driver which
makes all operations on memory buffer. After each screen write
Flush() method is called which check for dispcount() and if
it's 0 then call Refresh() method to update modified area by
Redraw() method. This method is dummy in GTNUL and external
output with this GT can be reached by outstd()/outerr() which
are now redirected to GT methods. A simple GT driver may overload
only Refresh() method to give full screen output.
Application can use only this GT driver and it seems to be very
good choice for GUI and background daemon/service programs.
This GT is loaded at startup then all other GTs can be loaded
later and inherit from the previously loaded GT drivers.
The new GT driver can overload as much method as wants/needs.
Now all GT operations are implemented as GT method so GT driver
can easy change their default behavior, f.e. it may fully overload
color parsing methods and use differ or extended to Clipper color
definitions.
I rewrote all existing GTs to work with new GT model.
OS2 users - please test GTOS2 which I was not able to test and
see the note in Redraw() method. If possible please make some
speed tests.
In fact now there is much more internal operations then it was
before but because they are done on memory only then current
code is much faster in this GT drivers which so far makes all
operations on real video area. I made some tests with GTNUL
and tests/vidtest.prg and the total overhead is minimal. Now
dipbegin()/dispend() in practice does not cost anything so it
gives additional speed improvement in application which extensively
use it.
More then one GT driver can be linked with final binaries and
chose on application startup by //GT<NAME> switch and/or environment
variable HB_GT=<name>
In the RTL is new GT function GTSYS() which works in similar way
to RDDSYS() in RDD subsystem and for linking default GT driver
for given platform. When RTL is compiled the default GT driver
is set to HB_GT_DEFAULT envvar and if not exist to HB_GT_LIB
envvar and if it also does not exist to hard coded platfom GTs
(see source/rtl/gtsys.c and source/rtl/Makefile for rules)
Adding to source code:
ANNOUNCE GTSYS
disable linking the default GT driver and:
REQUEST HB_GT_<name>
for linking given (<name>) GT driver, f.e.: REQUEST HB_GT_WIN
If you are working in SH environment (Linux and other *nixes users,
DJGPP bash, MinGW shell then it's possible to use -gt<name> switch
in hblnk / hbmk scripts to force linking GT drivers (it could be
repeated with different <name>) and the first one becomes the default
one. F.e.:
xhbmk -m -n -w -es2 -gtcrs -gtsln -gtstd -gtpca vidtest.prg
Usually the GT driver are loaded at HVM startup but it's possible
to load it later. I created new GT driver CTW which gives full
CT3 like Window system. The CT3 extended driver change the behavior
of some function in Clipper extended driver, f.e WRITECON() or
SETPOS() with parameters out of screen range. So I implemented it
CTW as RT GTs which is loaded when some of CTWIN function is used
(f.e. WOPEN()/WBOARD()) and inherits from any existing GT driver.
This is full CT3 WIN implementation with all detail behaviors I
found (with some CT3 bug fixes). It does not have any CT3 limitations
and can be used for any virtual screen/window size though I hardcoded
CT3 limitation for backword compatibility. If somone will want to
remove it then it will be enough to delete few lines from ctwin.c
file. I'm not CTWIN Clipper user so maybe I missed some side effects
in this driver and was not able to well test it so if you will find
any incompatibilities then please inform me.
THe default GT buffer uses 32bit character cell internally but
in savescreen/restscreen it uses VGA compatible two bytes character
cell. Some GT drivers may want to use differ character cell.
Now GTCRS and GTSLN use 32bit character cell by default. They
need additional information about character set (box/normal) to
properly display box characters. It is possible to force in this
GT drivers using Clipper compatible character cell by calling:
hb_gtInfo( GTI_COMPATBUFFER, <lCompat> ) -> <lPreviousSeting>
but in may cause that box drawing characters will be lost in
some countries after RESTSCREEN(). It will depend on used code
page.
HB_GTINFO() is new function which works in similar way to DBINFO()
in RDD. It allows to retrieve/change some of GT driver settings.
GTI_* actions are defined in hbgtinfo.ch - it has all GTI_*
definitions used in xHarbour. Now in Harbour only few of them
are implemented.
The new three .prg functions:
HB_SETKEYCP( <cTermCP> [,<cHostCP>] )
HB_SETDISPCP( <cTermCP> [,<cHostCP>] [,<lBoxChar>] )
HB_SETTERMCP( <cTermCP> [,<cHostCP>] [,<lBoxChar>] )
have been added. They set automatic input (HB_SETKEYCP)
and output (HB_SETDISPCP) (or both: HB_SETTERMCP) character
translation. They are also important for some GTs which
informing them about used internal code page for unicode
translation (GTXWC, GTSLN) and/or chosing proper character
set (standard/alternate) for letters and other (f.e. box
drawing characters) (GTCRS, GTSLN),
<cTermCP> is encoding used on external (terminal) side
<cHostCP> is encoding used internally, if not given then
current code page set HB_SETCODEPAGE() is used.
some of GTs which uses unicode output may
ignore <cTermCP>
<lBoxChar> is optional parameter which interacts with dispbox()
output disabling switching to alternate character
set in some GTs. It effectively causes that if internal
(host) code page contains some letters on the box char
positions then they will be shown also by box drawing
functions like dispbox() instead of CP437 characters.
In some cases it could be useful. By default lBoxChar
is not set and GTs which can switch between standard
and alternate character set (GTCRS, GTSLN) will try to
use alternate character set for box drawing functions.
Victor: I removed some of your functions. They can be very easy
implemented with hb_gt_GetChar()/hb_gt_PutChar() but I do not want to
make them part of documented external API because some GT drivers may
want to use absolutely differ color definitions and they will stop to
work so I do not want to make this functions documented external API.
Ryszard: Setting alternative debug keys does not longer work.
I like such possibilities but it should be implemented in differ
way to f.e. using HB_GTINFO interface to allow low level GT driver
extensions, f.e. in *nixes using CTRL+[A-Z] and SIGINT, SIGQUIT,
SIGTSTP signals for real asynchronous setting of debug/cancel flag
without keyboard polling from main HVM loop. I would like to discus
about such more general solution.
