which converts item string buffer to writable state to use with
functions like FREAD() instead of hb_itemUnShare*()
* updatd other code to respect above modifications
! fixed bugs (also GPF traps) located by above modifications
TODO: please make build tests. Especially in OS2 - not tested at all.

* harbour/source/vm/fm.c
+ added support for thread local memory allocators by using MSPACE
mechanism in DLALLOC.
It can be enabled by compiling Harbour with HB_FM_DLMT_ALLOC macro.
By default up to 16 (HB_MSPACE_COUNT macro) independent memory
allocators is dynamically created for new threads. When more threads
is used then allocators are shared between them and HVM tries to
balance used allocators to reduce number of threads using the
same allocator.
It should give noticeable scalability improvement in some OS-es
where default memory manages has pure MT performance.
Please try to compiler speedtst.prg with Harbour compiled with
and without HB_FM_DLMT_ALLOC and compare results in this test:
speedtst --thread=2 --scale
using real multiCPU machine.
* harbour/source/vm/dlmalloc.c

* harbour/include/hbstack.h
! disabled inline assembler code to retrieve HVM stack pointer from TLS
in Win64 builds. In summary I do not even know if Win64 uses the same
memory addresses for TLS as Win32 so it's not safe to enable such code

have fast enough native TLS support.

* harbour/include/hbstack.h
* added alternative asm inline function to __MINGW32__ builds which
operates on 64bit pointers. It's used when __MINGW64__ macro is
defined. I do not know if such macro existing in 64bit MinGW version.
* harbour/include/hbdefs.h

* harbour/source/vm/hvm.c
* harbour/source/debug/dbgentry.c
* changed the method of static variable handling. Now we do not
have centralized array of all statics used by application (s_aStatics)
but each module uses it's own array to keep statics. The old
s_aStatics has been removed. It means that loading new PCODE module
from .hrb file or shared/dynamic library does not cause any static
table reallocation so it does not creates potential GPF trap for MT
code which may operate on static vars.
This modification changed a little bit the debugger interface.
I also updated some unused by us debug functions like __DBGVMVARSLIST()
or __DBGVMVARSLEN() anyhow any 3-rd party debuggers should be
updated for new API and modified hb_dbgEntry() syntax.

* harbour/include/hbthread.h
* harbour/source/vm/thread.c
+ added hb_atomic_set(), hb_atomic_get(), hb_atomic_inc() and
hb_atomic_dec() functions which operates on HB_COUNTER or smaller
type if it's necessary for some platforms which can be access/assign
increment/decrement in MT safe atom operations.

* harbour/include/hbstack.h
* harbour/include/hbthread.h
* harbour/source/vm/estack.c
* harbour/source/vm/thread.c
* harbour/source/vm/hvm.c
+ added support for I18N in HVM.
Each thread can have it's own i18n set.
When new thread is created then it inherits i18n set from parent
thread and both uses the same set (please remember about it if you
will want to make some direct modifications on active i18n set
internals).
When thread change active i18n set then it effects only this thread
and new threads which will be create later. It does not change i18n
in other existing threads.
+ added functions to set/get pointer to active i18n set in HVM
void * hb_vmI18N( void )
void hb_vmSetI18N( void * )
* harbour/include/hbapi.h
* harbour/source/rtl/hbi18n.c
+ added i18n module. Now only for internal Harbour usage without support
for optional switching to alternative implementations.
I'll add such functionality later when I will work on native gettext
support.
The following public .prg functions has been added:
HB_I18N_GETTEXT[_STRICT]( <cMsgID> [, <cContext> ] )
-> <cTranslatedMsgID> | <cMsgID>
HB_I18N_NGETTEXT[_STRICT]( <nValue>, <cMsgID> | <acMsgID> ;
[, <cContext> ] )
-> <cTranslatedMsgID> | <cMsgID> | <acMsgID>[ <nIndex> ]
This is minimal support necessary for .prg code which has to exists
in each i18n module working with Harbour.
The following functions had been added as public C API:
PHB_ITEM hb_i18n_gettext( PHB_ITEM pMsgID, PHB_ITEM pContext )
PHB_ITEM hb_i18n_ngettext( PHB_ITEM pNum,
PHB_ITEM pMsgID, PHB_ITEM pContext )
The following functions had been added as private HVM C API:
void hb_i18n_init( void )
void hb_i18n_exit( void )
void hb_i18n_release( void * cargo )
void * hb_i18n_alloc( void * cargo )
They have to be supported by alternative i18n modules
The following functions has been added to manage Harbour i18n
translations sets:
HB_I18N_CREATE()
-> <pI18N>
Creates new empty I18N translation set
HB_I18N_CODEPAGE( [<pI18N>,] [<cNewCP>], [<lBase>], [<lTranslate>] )
-> <cOldCP>
Gets or sets Harbour codepage used by translation set
<pI18N> - I18N translation set,
if it's not given then currently active I18N set is used
<cNewCP> - new CP ID. Must be linked with application
<lBase> - when it's .T. then get/set base massages CP instead of
translated massages CP
<lTranslate> - if it's .T. then translate base (<lBase>==.T.) or
final messages in I18N set from previous CP to
given one. Base messages translation in synced
with context ID translation.
HB_I18N_PLURALFORM( [<pI18N>,] [<cNewForm>|<bNewForm>], [<lBase>] )
-> <cOldForm>|<bOldForm>
Gets or sets plural form used for final or base messages
<pI18N> - I18N translation set,
if it's not given then currently active I18N set is used
<cNewForm> - language ID of plural form, f.e.: "EN", "PL", "LT".
Now only three above are supported. Please add rules
for other languages to source/rtl/hbi18n.c.
<bNewForm> - codeblock used to calculate plural form indexes.
can be used instead of character representation but
it's not storred in serialized I18N set
<lBase> - when it's .T. then get/set base massages plural form
instead of translated massages one.
HB_I18N_DESCRIPTION( [<pI18N>,] [<cNewDescription>] )
-> <cOldDescription>
Gets or sets translation set description. After serialization
up to 32 bytes is stored in header which can be easy used to
determinate type of translation file.
<pI18N> - I18N translation set,
if it's not given then currently active I18N set is used
<cNewDescription> - new description
HB_I18N_ADDTEXT( <pI18N>, <cMsgID>, <cTrans> | <acTrans> [, <cContext> ] )
-> NIL
Adds new message with translation to i18n translation set
<pI18N> - I18N translation set
<cMsgID> - original message
<cTrans> - translated message
<acTrans> - array with translated messages used for plural forms
<cContext> - message context
HB_I18N_SET( [ <pI18N> | NIL ] )
-> <lActive>
Sets given I18N translation set as default one used by
HB_I18N_[N]GETTEXT[_STRICT]() functions or remove translation
set for calling thread when passed parameter is NIL
<pI18N> - I18N translation set
Returns logical value which is .T. when i18n set is active
HB_I18N_SAVETABLE( [<pI18N>] )
-> <cTable>
Returns I18N translation as string item which can be stored
in file or database
<pI18N> - I18N translation set, if it's not given then currently
active I18N set is used
HB_I18N_RESTORETABLE( <cTable> )
-> <pI18N> | NIL
Restores I18N translation set from strin item.
<cTable> - I18N translation set in string representation
On success it returns new <pI18N> set otherwise NIL if <cTable>
is not valid item created by HB_I18N_SAVETABLE() or it's corrupted.
HB_I18N_HEADERSIZE()
-> <nHeaderSize>
Returns size of header used by i18n serialized version
HB_I18N_CHEK( <cTable> | <cHeader> [, @<cDescription> ] )
-> <lValid>
<cTable> - i18n translation set serialized by HB_I18N_SAVETABLE
<cHeader> - header of i18n translation set
( LEFT( <cTable>, HB_I18N_HEADERSIZE() )
<cDescription> - optional parameter passed by reference where
will be sored i18n translation set description
extracted from valid header
Returns logical value indicating if given table or header is
valid serialized by HB_I18N_SAVETABLE() data. It does not
decode the table though it validates size and control sums.
These functions are optional and some future alternative implementations
may not support all of them and/or may provide some other functions.
+ added unofficial .prg function __I18N_HASHTABLE() which allows to
access hash table used by i18n translation set or create new translation
set with given hash table. It's helper functions for developers which
will work on Harbour i18n tools and should not be used by Harbour users.
Unlike original gettext Harbour allows to use language with many
plural forms as base one. In such case programmer should activate
at application startup default i18n translation set with base plural
form valid for base application language, f.e. by:
pI18N := hb_i18n_create()
hb_i18n_pluralForm( pI18N, <cLangID> | <bForm>, .t. )
hb_i18n_set( pI18N )
.prg code example:
#xtranslate _( <x,...> ) => hb_i18n_gettext_strict( <x> )
#xtranslate _N( <x,...> ) => hb_i18n_ngettext_strict( <x> )
proc main()
local pI18N, i
pI18N := hb_i18n_create()
hb_i18n_pluralForm( pI18N, "PL", .t. )
hb_i18n_set( pI18N )
for i := 0 to 30
? i, _N( i, {"grosz", "grosze", "groszy"} )
if i > 0 .and. i % 10 == 0
wait
endif
next
return
In .pot files created during compilation by Harbour with -j option
for above code we have the following entries for message with plural
forms:
msgid "grosz"
msgid_plural "grosze"
msgid_plural2 "groszy"
msgstr[0] ""
The msgid_plural2 (and others if language has more plural forms)
is Harbour extension which is not gettext compatible.
The above implementation is base version but should be fully functional.
Now we will need functions to safe/read i18n files and tools to mange
.pot files: merge them, edit translations, create final binary i18n
translation sets. Because we are using gettext compatible .pot files
then for some of such jobs we can use original gettext tools but we
need at least function which will create translation set from one or
more .pot files.
We should also agree some default localization(s) for files containing
translated data, their name convention and environment variable(s)
to set default language. It's not strictly necessary and each user
can have his own implementation but it would help in adding new
translations by final users to any Harbour application which will
respect them. We can use LANG envvar to extract preferred language
and use the same path as executed application looking for files
<appname>-<lang>.hil files though it may create some problems for
OSes which support only 8.3 file names so we can also define that
HB_I18N envvar has higher priority and points to expected translation
file.

- removed old __i18n_*() functions
+ added current i18n functions

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

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.

hb_fsTruncAt() to use with shared file handles.
Please test it in other *nixes. I used pread[64]()/pwrite[64]()
POSIX functions but I do not know if they are available by default
in other supported platforms like MacOSX, BSD, HPUX, SunOS.
If not they I will have to implement some workaround.
* harbour/common.mak
* harbour/source/rtl/Makefile
* harbour/include/hbapifs.h
+ harbour/source/rtl/filebuf.c
+ added set of new file functions (hb_file*()) which are designed to
use with shared file handles and locks (buffers in the future):
hb_fileExtOpen(), hb_fileCreateTemp(), hb_fileClose(), hb_fileLock(),
hb_fileReadAt(), hb_fileWriteAt(), hb_fileTruncAt(), hb_fileSize(),
hb_fileCommit(), hb_fileHandle()
These functions operate on PHB_FILE structure instead of HB_FHANDLE.
Now in POSIX systems they share file handle between aliased or
simultaneously open by other thread work areas. It resolves the
problem with releasing all process FCNTL locks by any close()
operation even on duplicated or open() separately handle.
Now DOS deny flags emulation works in single process even if
BSD locks are disabled (non Linux *nixes).
They also keep internal file lock list what allows to synchronize
threads and aliases with file locks in POSIX systems. In the future
it will be used also for internal locking to synchronize threads
without OS level locks - pseudo exclusive mode in cloned WA.
Finally these structures will be used also for file buffers
which will be shared between aliased WA and threads.

* 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 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

THREAD STATIC <varname [:= <exp>], ...>
They work like normal static variables but each thread operates
on its own copy.

* 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.

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.

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

! added protection against cyclic references in arrays
* eliminated action parameter from hb_vmRequestReenter() /
hb_vmRequestRestore()
* moved s_lRecoverBase and s_uiActionRequest to HB_STACK structure
for future MT HVM version
+ added internal item structure hb_struRecover - it's not real item
but this structure is used to keep information about BEGIN SEQUENCE
data - it reduce HB_STACK usage
+ added support for ALWAYS clause in BEGIN SEQUENCE
The syntax is:
BEGIN SEQUENCE
<code>
[ RECOVER [ USING oErr ] ]
<recoverCode>
[ ALWAYS ]
<alwaysCode>
END [ SEQUENCE ]
It's guaranteed that <alwaysCode> is _ALWAYS_ executed even if
inside <code> or <recoverCode> some new exceptions like RETURN,
BREAK or QUIT will appear.
Please note that when the following code is executed:
BEGIN SEQUENCE
<code>
ALWAYS
<alwaysCode>
END
(without RECOVER clause) then BREAK exception inside <code> is not
recovered, <alwaysCode> is executed and then BREAK exception is
passed to outer BEGIN SEQUENCE. This is the same semantic as
used in TRY / [ CATCH ] / FINALLY / END
Those of you who prefer to use TRY / CATCH / FINALLY / END instead
of BEGIN SEQUENCE / RECOVER / ALWAYS / END can simply add to your
source code:
#command TRY => BEGIN SEQUENCE
#command CATCH [ oErr ] => RECOVER [ USING <oErr> ]
and:
errorBlock( {|oErr| break( oErr ) } )
Though instead of 'break( oErr )' I suggest to use some small function
which will support some basic recovery/substitute operations like in
default errorsys() and LockErrHandler() to not break existing code
which may depends on the default behavior.
If you want I can add direct support for TRY / CATCH / FINALLY / END
but I'm not sure it's really necessary.
Please note also that in Harbour ALWAYS code is execute even for QUIT
excpetion.
When <alwaysCode> is executed current exception is stored and restored
when is finished. If new exception appears inside <alwaysCode> then
restored exception depends on the priority in the following order:
QUIT // highest priority
BREAK
RETURN
If both exceptions have the same priority and contain additional value
(error object in BREAK or return value in RETURN) then the recently set
one is restored. It's similar behavior to destructor code.
* harbour/source/common/hbstr.c

* tuned error messages to be more Clipper compatible
% use static strings from hb_szAscii
* harbour/source/rtl/alert.prg
* use hb_gtInfo( GTI_FULLSCREEN ) to detect type of GT driver
! some minor fixes
TOFIX: we have to also use GTI_ISCTWIN or add window allocation
to standard GT drivers to be Clipper compatible when CTWIN
is used - In Clipper Tools ALERT() works in differ way then
the standard one. It creates separate window box to display
data, supports SETKEY(), etc. I'll think about adding some
extended support for ALERT() and similar operations (f.e.
separate debugger windows) to GT API so it will be also
possible to overload standard alert() command by GUI message
box in GTGUI and similar GT drivers.

* harbour/source/vm/proc.c
+ added startup symbol to hb_stack. It gives very good stop
condition for all procedures which trace stack calls and
resolves the problem with hb_stack.pBase which was never
pointing to valid function/procedure symbol when no symbol
was put on HVM stack. Now after hb_stackInit() the first
item is allocated for "hb_stackInit()" symbol so hb_stack.pBase
is always a pointer to valid function/procedure symbol.
* changed the guard condition for buggy code in hb_stackPop()
and similar code from:
hb_stack.pPos < hb_stack.pItems
to:
hb_stack.pPos <= hb_stack.pBase
The old condition was generating usable error message only in the
startup function. In deeply called functions it was only waste of
CPU time on one of the most often call functions. Before it was
activated internal stack structures were corrupted.
If we were leaving for many years without really working stack
underflow protection then maybe we should think about disabling
it at when HB_STACK_MACROS are used and keep it only in real
stack functions for HVM developers. Single protection in
hb_stackOldFrame() I've just added is enough for basic C code
validation.
I created the second version of stack macros without it in
hbstack.h but I would like to hear other developers opinion.

* harbour/include/hbapi.h
* moved HB_STACK_STATE declaration from hbstack.h to hbapi.h
it's covered by _HB_API_INTERNAL_ macro so it should not
effect 3-rd party code
* modified hb_struSymbol structure:
LONG stackbase
replaced by:
PHB_STACK_STATE stackstate
this modification allows to keepadditional information bound with
function call stack accessible from different HVM modules.
Now it's used by memvars code to keep/update PRIVATE variables
stack pointers. I plan to store in HB_STACK_STATE structure
information additional information for classes code like super
casting or instance variables offsets in new OOP model I'm working on.
It can be also used by debugger code to retrieve some informations
about executed functions without active updating by main HVM loop.
+ added hb_memvarsClear() - cleanly clears all PRIVATE and PUBLIC
variables
+ added hb_memvarUpdatePrivatesBase() - updates PRIVATE stack base
offset so PRIVATE variables created in current function/procedure
will not be removed when it returns
- removed hb_memvarsRelease() and hb_memvarValueNew()
* harbour/include/hbstack.h
+ added hb_stackClearMevarsBase() - helper function for hb_memvarsClear()
clears PRIVATE stack offsets in executed functions
* changed to static offset from int to long - in different places we
were using int or long in HVM so I cleaned the HVM code to always
operate on the same type
* harbour/source/vm/estack.c
* set/restore PRIVATE stack base offset in hb_stackNewFrame()/
hb_stackOldFrame()
* updated for new HB_IT_SYMBOL structure
* harbour/source/vm/hvm.c
! removed setting/restoring PRIVATE stack base offset in hb_vmExecute()
It make code like:
eval(&("{||VAR:=1}"))
Clipper compatible
* updated for new HB_IT_SYMBOL structure
* changed order of execution exit procedures for clean memvars removing
and future destructors execution. I'll describe it better when I'll
add destructors.
* harbour/source/vm/memvars.c
! fixed CLEAR MEMORY - now this function should be safe in Harbour
It's not exactly compatible with Clipper because I intentionally
didn't replicated some Clipper bugs like possible memory corruption.
+ added hb_memvarsClear() - cleanly clears all PRIVATE and PUBLIC
variables
+ added hb_memvarUpdatePrivatesBase() - updates PRIVATE stack base
offset so PRIVATE variables created in current function/procedure
will not be removed when it returns
! fixed releasing PUBLIC and PRIVATE variables which were passed by
reference and are still active on HVM stack or in codeblocks as
detached locals (see: hb_memvarDetachDynSym())
* modified hb_memvarFindSymbol() to be more Clipper compatible
% optimized hb_memvarRelease() to operate or PHB_DYNS instead of
string comparison and not make linear dynamic symbol scan for
PUBLIC or not existing symbols
- removed hb_memvarReleasePublic()
* harbour/include/hbvmpub.h
* harbour/include/hbxvm.h
* harbour/source/compiler/gencc.c
* harbour/source/vm/classes.c
* harbour/source/vm/debug.c
* harbour/source/vm/itemapi.c
* harbour/source/vm/pcount.c
* harbour/source/vm/proc.c
* harbour/source/vm/pvalue.c
* updated for the above modifications
* harbour/source/rtl/memvarbl.prg
* harbour/source/rtl/menuto.prg
* use __mvEXIST( cMemvar ) instead of __mvSCOPE( cMemvar ) > HB_MV_ERROR
__mvEXIST() is much faster function
* harbour/source/rtl/type.c
* execute hb_memvarUpdatePrivatesBase() after macro type checking.
This should not be necessary but we are not Clipper compatible here
and this is work around for difference in our TYPE() implementation.
Clipper for:
? TYPE("VAR:=1")
create PUBLIC variable VAR when [x]Harbour PRIVATE one.
Should we try to make it Clipper compatible?
The above should fix problems reported with memvars. We are not 100%
Clipper compatible but unlike in Clipper we cannot break VM internals
using some operation on references to memvars and detached locals
and/or RELEASE.../ CLEAR MEMORY. This modifications should be intensively
tested. If you will find any problems with current code please inform me.
I'd like to hear your opinions about memvars created by TYPE() (see above).
Should we change it? It may not be very easy operation - we will have to
change macro compiler and add new PCODE for that.

We still have some public functions which are not used by core code
and not declared in header files, like:
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/hbstack.h
* harbour/source/vm/estack.c
+ added:
int hb_stackCallDepth( void )
LONG hb_stackBaseProcOffset( int iLevel )
* harbour/source/vm/arrays.c
* harbour/source/vm/proc.c
* use hb_stackBaseProcOffset()
* harbour/source/vm/hvm.c
- removed s_ulProcLevel used by HB_DBG_PROCLEVEL() - count the call
stack dynamically using stack data - a little bit slower but it's
not widely used function, now is MT safe and we eliminated some
small overhead in each function call so statistically we improved
overall performance

* harbour/include/hbstack.h
* harbour/source/vm/estack.c
- removed hb_stackTopItem()
+ added hb_stackItemBasePtr(), hb_stackAllocItem()
* changed the item initialization/clearing in push/pop operation
Now only complex item are cleared and it's not guaranteed that
the top item will be set to NIL. In fact it was not guarantied
even before my modifications. You coule be sure only that the
allocated item will not be complex one and you can safely pass
pointer to it to any other functions. It allow to clean a little
bit some code and remove redundant and repeated setting HB_IT_NIL
for allocated items.
Now using hb_stackPush() can be necessary only in some very seldom
cases. hb_stackAllocItem() allocates new item and returns pointer
to this item. After some code cleaning hb_stackPush() is not used
by core Harbour code at all so if you have it in your sources then
please check if you should not update them.
* harbour/source/rdd/usrrdd/usrrdd.c
* use hb_vmPushNil() instead of hb_stackPush()
* harbour/source/vm/arrays.c
* changed hb_arrayNew() to be safe for automatic GC activation
* some minor speed improvement
* harbour/source/vm/codebloc.c
* changed hb_codeblockNew() and hb_codeblockMacroNew() to be safe
for automatic GC activation
* harbour/source/vm/debug.c
* use only stack function/macros instead of direct accessing hb_stack
I hope that I haven't break anything.
* harbour/source/vm/hvm.c
! use hb_stackAllocItem() instead of hb_stackTopItem() to make our
HVM reentrant safe. This modifications also fixed some possible
bugs which could be exploited by other modules which have to execute
.prg code - f.e. in RDD when relation codeblock has to be executed
to position record in fieldget/fieldput operations.
* harbour/source/vm/itemapi.c
* harbour/source/vm/memvars.c
* use hb_stackAllocItem()
The above modifications finish stack usage and making our HVM reentrant
safe. There is only one thing which have to be fixed yet. It's HVM
support for xbase++ syntax in things like:
func(&<paramList>), aVal[&<indexList>], {&<itemList>}
To fix it we will have to change PCODE generated by compiler and
replace some PCODEs used for current code by the new one. I will
wait with this modifications for Ryszard.
With the above exception now we are ready to implement destructors,
add automatic GC and begin to work on MT though before that I'd like
to clean the RT error support.
Please carefully check if all is correct. It was modification in core
code and even small typo can break whole application.

Warning!!! hb_stackTopOffset() returnes results smaller by 1.
The TOP stack item is undefined and should not be accessed by
debuger.
* changed HB_DBG_VMSTKGLIST() to operate on functions/macros.
It's possible that the above will badly interact with core debugger
code so I stop farther modifications leaving them for someone who
knows debugger core code.

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.

* harbour/include/hbxvm.h
* harbour/source/vm/hvm.c
+ added hb_xvmArrayItemPush(), hb_xvmArrayItemPop(), hb_xvmMultByInt()
* harbour/source/compiler/gencc.c
% use hb_xvmArrayItemPush(), hb_xvmArrayItemPop(), hb_xvmMultByInt()
If someone has time then it will be good to also add:
hb_xvmDivByInt(), hb_xvmModulusInt(), hb_xvmPlusInt(), hb_xvmMinusInt()
* harbour/source/vm/itemapi.c
* use simple memcpy() in hb_itemSwap() - it's save in current HVM
It could become unsafe if we add reference tracing or sth like
that in the future but in such case we will have to also update
hb_itemCopy() and hb_itemMove() so we can also update hb_itemSwap()
* harbour/source/vm/asort.c
* harbour/source/vm/classes.c
* harbour/source/vm/memvars.c
* harbour/source/vm/hvm.c
* cleaned the code which created HB_ITEMs on C stack. Only three
places have to be update yet and array/clodeblock creation little
bit modified and we will be able add automatic GC activation in
hb_xgrab() or hb_gcAlloc().

* 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.

% 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

added support for slang 1.4x patched for UNICODE (Debian
patches used by most of current Linux distributions) and
slang 2.x - It's unicode ready, tries to detect terminal mode
(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
loaded (f.e. the one created by QRCZAK)

code form xHarbour - this GT can work in XWindow environment only
and create its own window for console output. It delays the
initialization to the moment when user try to display anything on
the screen so even without X Window system programs which uses this
GT can work as long as use only outstd/outerr output.

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.
