* source/vm/hvm.c
+ Added hb_vmSetLinkedMain() function to replace direct
access to exported variable hb_vm_pszLinkedMain.
(it's not a public call and caller should always pass
a string literal).
* hb_vm_pszLinkedMain -> s_vm_pszLinkedMain and made static.
* utils/hbmk2/hbmk2.prg
! Not adding 'dllimport' for externs in C stub when
MSVC is used, to avoid compiler warning mentioned in
previous entry.
* utils/hbmk2/hbmk2.prg
* bin/hb-func.sh
* Updated for above change.
; TODO: Convert GT defaulting to function call too.
* harbour/include/hbapi.h
* harbour/source/vm/cmdarg.c
* harbour/source/vm/hvm.c
* added hb_cmdargUpdate() function which makes final argc/argv updating
(code moved from hb_cmdargInit())
! use hb_cmdargUpdate() - it fixes GPF in MT mode when some fs* functions
were called before allocating HVM stack
; TOFIX: change some hb_setGet*() functions to work without HVM stack.
* harbour/source/rtl/hbtoken.c
* formatting
* harbour/source/vm/fm.c
! fixed typo in default FM module setting/
* harbour/include/hbapicls.h
* harbour/source/vm/classes.c
* harbour/source/debug/dbgentry.c
* renamed hb_dbgObjSendMessage() to hb_dbg_objSendMessage() to keep
naming convention used for other C debugger functions
* harbour/source/vm/debug.c
* added information about existing debugger functions and where they
are used.
* harbour/include/hbvm.h

* harbour/source/vm/codebloc.c
* harbour/source/vm/estack.c
* 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.

if integer overflow forces conversion to double item
* some minor optimizations
* harbour/source/rtl/rat.c
* formatting
* 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.
hb_atomic_dec() returns true if counter is 0 after decrementation

! fixed wrongly recognized functions with HB_I18N_ prefix as
HB_I18N_GETTEXT()
* harbour/include/hbapi.h
* 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.
* harbour/include/hbextern.ch
- removed old __i18n_*() functions
+ added current i18n functions
* harbour/include/hbvmpub.h
+ added HB_VM_ISFUNC(), HB_VM_FUNCUNREF() and HB_VM_EXECUTE()
macros to operate on HB_SYMB structure
* harbour/source/vm/hvm.c
* harbour/source/vm/classes.c
* use HB_VM_ISFUNC()/HB_VM_FUNCUNREF()/HB_VM_EXECUTE() macros
for executing function inside HB_SYMB structure to avoid possible
synchronization problems during modifications
* harbour/include/hbxvm.h
* harbour/source/vm/hvm.c
* harbour/source/compiler/gencc.c

* harbour/source/vm/estack.c
* harbour/source/vm/hvm.c
* harbour/source/vm/thread.c
* harbour/source/rtl/hbgtcore.c
+ added support for optional allocating independent console window by
each thread. By default new thread inherits console Window from
parent thread. But each thread can allocate its own console window
by calling hb_gtReload( <cGtName> ) function, f.e. by:
hb_gtReload( hb_gtVersion() )
If GT driver supports such functionality then new it will allocate
new console windows.
Each console window has reference counter which is increased when
new thread starts and decreased when hb_gtReload() is executed or
thread terminates. When counter reach zero give console window is
destroyed.
* harbour/source/rtl/gtwvt/gtwvt.c
! use SendNotifyMessage() instead of SendMessage() to not block
threads which inherited GT from parent thread. Why non of MS-Win
users reported this problem?
+ added reference counter to window class for multi GT support
+ harbour/tests/mt/mttest10.prg
+ added demonstration/test code for using independent console window
in different threads. It needs GT driver which supports such
functionality, f.e GTXWC in *nixes or GTWVT in MS-Windows
* harbour/tests/mt/mttest09.prg
! fixed typo in comment
* harbour/include/hbstack.h
* harbour/source/vm/estack.c
* harbour/source/vm/hvm.c
* harbour/source/debug/dbgentry.c
* harbour/source/debug/debugger.prg
* moved debugRequest flag and debugger internal structure
pointer to HVM stack
* allocate debugger internal structure dynamically in thread
thread local area when PCODE with debug information is executed
* changed STATIC s_oDebugger to THREAD STATIC
* send HB_DBG_VMQUIT after each thread termination when
debugger is activated
Now debugger can be used in MT programs and each thread can be
debugged separately (each has its own debuger). Please only
remember that thread sharing console window can overwrite other
threads debugger screen. There is also one limitation which I'll
try to remove later: only main thread debugger keeps information
about file wide STATIC names and line numbers with possible break
point places. This data should be shared between debuggers.
* harbour/include/hbapi.h
* harbour/source/vm/hvm.c
* harbour/source/vm/estack.c
* disabled all debugger related bindings and variables when
HB_NO_DEBUG macro is set
% moved s_fDebuging to HVM function stack frame to eliminate
saving/restoring this variable in each function/message call
Note: if you think it's good to block linking .prg code compiled
with -b (debugger support) with HVM compiled with HB_NO_DEBUG
then it's enough to disable whole hb_dbg_SetEntry() function
in hvm.c when HB_NO_DEBUG macro is set.
* harbour/source/rdd/wacore.c
; updated comments about xbase++ behavior in dbRelease()
* harbour/include/hbvm.h
* harbour/source/vm/hvm.c
* harbour/source/vm/dynlibhb.c
* harbour/source/vm/runner.c
! added MT protection for HB_LIBLOAD()/HB_LIBFREE() and
HB_HRBLOAD()/HB_HRBUNLOAD(). Please remember that you should
not use any external LoadLibrary() functions because they are
not protected for clean PCODE modules loading/unloading even
in ST mode. Using them can cause HVM internal structure corruption.
If we have such functions in contrib then they should be redirected
to our HVM ones.
There is still one problem in MT mode which has to be resolved yet.
When dynamic library containing PCODE using static variables
is loaded 1-st time then it will force resizing of internal array
with static variables. If in exactly the same moment some other
thread operates on static variable then it may cause corruption.
To resolve this problem we will have to divide continuous memory
block common for all modules where we store all static variables
into separated blocks bound with each PCODE module (symbol table).
* harbour/source/vm/dynlibhb.c
+ added support for DLL loading/unloading in OS2 builds.
Based on xHarbour code by Maurilio Longo - please test.

in one very specific situation. It's documented and expected
behavior
* harbour/source/rtl/hbgtcore.c
+ added support for retrieving current HB_GTI_NOTIFIERBLOCK code block
+ added support for removing HB_GTI_NOTIFIERBLOCK code block without
setting the new one
* harbour/source/vm/garbage.c
* unblock HVM before executing destructors and releasing blocks
* harbour/source/vm/fm.c
! do not call internal error with active lock when FM statistic
is enabled
* harbour/source/vm/thread.c
! stop other threads in hb_threadOnce() if the 1-st one
executes bAction block to be sure that it will be completed
before thread leave hb_threadOnce() function
* harbour/source/vm/set.c
! do not call hb_inkeyReset() in set release. It's not necessary
and it could change keyboard buffer size for other threads using
the same GT driver.
* harbour/source/vm/hvm.c
% allocate new thread stack without lock
* harbour/source/rtl/hbgtcore.c
* harbour/source/rtl/gtapi.c
* moved clipboard resetting from hbgtcore.c to gtapi.c
* harbour/source/rtl/filesys.c
! do not use read/write operations with given file offset in Win9X
which seems to not support such functionality
* harbour/include/hbvm.h
* harbour/source/vm/hvm.c

[TOMERGE 1.0]
* harbour/include/hbthread.h
* harbour/source/vm/hvm.c
* harbour/source/vm/thread.c
+ added .prg function
hb_threadWait( <pThID> | <apThID>, [ <nTimeOut> ] [, <lAll> ] )
=> <nThInd> | <nThCount> | 0
This function wait for <nTimeOut> seconds (default infinite wait)
until one or all (controlled by <lAll> parameter) of given HVM threads
will have finished execution in HVM area. It does not join the threads.
It returns index to 1-st thread which has finished execution (default)
or number of threads which has finished in given time period when lAll
is .T.
* harbour/include/hbstack.h
* harbour/source/vm/estack.c
* harbour/source/vm/hvm.c
% moved static USHORT uiPolls to HVM stack to not reduce the HVM
performance in MT mode. In multi CPU environment if many threads
try to change the same memory variable in the same time the overall
performance is strongly reduced on most of tested hardware - probably
some random CPU delay used to resolve the conflict.
* harbour/source/vm/hvm.c
! fixed last commit typo in thread number allocating - all threads
where using 0 number
* harbour/source/vm/thread.c
! fixed return value in recursive call to hb_mutexLock() - was FALSE
! fixed typo in timeout parameter number
should be 2 instead of 1
* harbour/source/rtl/tobject.prg
! fixed init() return value - it should be ignored and current

a second
* harbour/include/hboo.ch
* harbour/include/hbclass.ch
* harbour/source/vm/classes.c
* harbour/source/rtl/tclass.prg
+ added support for SYNC object and CLASS messages working like
in xBase++. Please remember that all locked by thread SYNC messages
objects and classes are unblocked automatically for the time which
thread spends in hb_subscribe[Now]() or signal:wait()
* harbour/tests/speedtst.prg
* marked T054 as memory tests
* harbour/source/vm/hvm.c
* harbour/source/vm/thread.c
* added hb_threadOnce( @<onceControl> [, <bAction> ] ) -> <lFirstCall>
This function allow to execute some code only once. It's usefull in
MT environment for initialization.
<onceControl> is variable which holds the execution status and have
to be initialized to NIL. In most of cases it will be simple static
variable in user code.
<bAction> is optional codeblock which is executed only once (on 1-st
call with given <onceControl>)
* harbour/source/rtl/filesys.c
! do not make any file name conversions in hb_fsNameConv() if HVM stack
is not allocated
* harbour/source/rtl/gtcrs/gtcrs.c
* casting
* harbour/tests/speedtst.prg
+ added support for --scale switch - it enables special mode
which compare scalability, f.e.:
./speedtst --thread=4 --scale
executes each test loop 4 times by single thread then
by 4 simultaneous threads, counts total real times in both
cases and presents them with the scale factor.
Please note that exactly the same loop tests are executed
simultaneously so this test should well show all places which
are not well scalable.
This test allows me to locate yet another memory variable written by
each thread on each function call just like uiPolls in main HVM loop.
It's s_bDebugging which is not used in MT mode because we do not have
any MT debugger yet but is was effectively killing the scalability
in my hardware.
If possible I would like to see some Windows results from multi CPU
machine with --scale parameter, f.e.:
speedtst --thread=8 --scale > speedtst.log
Please make some tests.
* harbour/source/vm/hvm.c
% do not assign s_bDebugging in hb_vmDo()/hb_vmSend() when debugger
is not linked
* harbour/source/vm/garbage.c
% enabled spinlocks in all x86 GCC builds
* harbour/include/hbvm.h
* harbour/include/hbthread.h
* harbour/source/vm/hvm.c
* harbour/source/vm/thread.c
+ added hb_vmThreadRegister() funtion which allows to register new
thread in HVM without HVM stack allocation
+ added hb_vmThreadRelease() which removes registered thread which
does not have allocated HVM stack yet
+ added hb_threadStateNew() which returns new thread control state
which can be used as parameter to hb_vmThreadInit(),
hb_vmThreadRegister(), hb_vmThreadRelease()
* register thread control state also for main thread
Now hb_threadSelf() returns thread pointer also for main thread
! fixed possible race condition in hb_threadWaitForAll() and
hb_threadTerminateAll() by using hb_vmThreadRegister() before
starting thread.

* harbour/ChangeLog
! corrected previous ChangeLog entry: instead of hb_waDetach()/
hb_waRequest() should be db_dbDetach()/hb_dbRequest()
* harbour/source/vm/hvm.c
* disabled PRG tracing in default builds. If someone wants to
use this feature then he should recompile Harbour with HB_PRG_TRACE
macro. In such case tracing can be enabled/disabled by __TRACEPRGCALLS()
function. HB_NO_TRACE macro is not longer usable - it's default in
current code.
* harbour/source/vm/classes.c
+ added PRG function __clsPreallocate() which extends the size of
classes buffer to given value to avoid later RT reallocations.
It may be useful in some very seldom cases for MT programs which
will allocate dynamically at runtime more then 16386 classes.
In practice rather impossible though who knows ;-)
* harbour/source/rdd/workarea.c
* set default preallocation size for RDD nodes to 128
+ added PRG function __rddPreallocate() which extends the size of
RDD nodes buffer to given value to avoid later RT reallocations.
It may be useful in some very seldom cases for MT programs which
will register dynamically at runtime more then 128 RDDs when other
threads are active and may use RDD nodes.

+ added ORDLSTDELETE() method.
Now ordbagClear() should work for DBFCDX.
* harbour/include/hbvm.h
* harbour/source/vm/hvm.c
* harbour/source/vm/thread.c
+ added .prg function hb_threadSelf() -> <pThID> | NIL
It returns thread ID pointer variable or NIL when thread was
registered without it (main thread and some 3-rd party threads
created by C API)
* harbour/source/vm/hvm.c
* protect s_InitFunctions and s_ExitFunctions by mutex
* harbour/source/common/hbverdsp.c
* use hb_verBuildDate() instead of __DATE__ and __TIME__ in
hb_verBuildInfo() function to report the same time in both
cases.
* harbour/include/hbapi.h
* harbour/source/vm/arrays.c
+ added hb_arrayGetPtrGC(), hb_arrayGetSymbol(), hb_arraySetSymbol()
* harbour/include/hbapi.h
* harbour/source/vm/dynsym.c
+ added hb_dynsymProtectEval(). Works like hb_dynsymEval() but
keeps dynamic symbol table locked during whole execution.
It's faster then hb_dynsymEval() but user function may not
access dynamic symbol tbale to not cause recursive locks
+ added protection against possible dynamic symbol table resizing
during hb_dynsymEval() by other threads.
* harbour/include/hbapi.h
* harbour/source/vm/memvars.c
+ added hb_memvarSaveInArray( int iScope, BOOL fCopy ) and
hb_memvarRestoreFromArray( PHB_ITEM pArray )
% use hb_dynsymProtectEval() in places where it's safe
* harbour/include/Makefile
+ harbour/include/hbthread.ch
+ added header file with thread constant definitions:
HB_THREAD_INHERIT_PUBLIC
HB_THREAD_INHERIT_PRIVATE
HB_THREAD_INHERIT_MEMVARS
HB_THREAD_MEMVARS_COPY
* harbour/include/hbthread.h
* harbour/source/vm/hvm.c
* harbour/source/vm/thread.c
+ added support for inheriting visible memvars from current
thread when new thread is created. Memvars in child thread
can be shared with parrent or they can be copied. See HB_THREAD_*
attributes defined in hbthread.ch, f.e.:
hb_threadStart( HB_THREAD_INHERIT_PUBLIC, @thFunc() )
or:
hb_threadStart( HB_BITOR( HB_THREAD_INHERIT_MEMVARS + ;
HB_THREAD_MEMVARS_COPY ), ;
@thFunc() )
Please note that when child thread creates new PUBLIC variable
which didn't existed when thread was started then it's visible
only for this thread and optionally for its child threads but
not for parent thread.
Please also remember that write access to shared memvars have
to be protected by users.
+ harbour/tests/mt/mttest08.prg
+ added test code for thread memvars inheritance
* harbour/bin/pack_src.sh
* added file list to archive so it's possible to recreate it later without SVN data
* harbour/common.mak
* harbour/make_b32.mak
* harbour/make_gcc.mak
+ added HBVMMT library for default builds
BCC version not tested - please test.
* harbour/source/vm/hvm.c
* moved language and code page setting before class and error initialization
* harbour/source/rtl/fserror.c
* harbour/source/rtl/fstemp.c
* harbour/source/rtl/fssize.c
* harbour/source/rtl/hbffind.c
* harbour/source/rtl/filesys.c
! fixed overloading FS error codes by other operations, f.e. accessing
TLS data by OS API function call
