; TOFIX: in practice all errors with RETRY flag generated by
other hb_errRT_*() functions have to be fixed because
new error object is created each time and informations
from previous one are lost, f.e. TRIES counter or CARGO

- removed hb_gtUnLoad() function
+ added hb_gtAlloc(), hb_gtRelease(), hb_gtAttach()
+ added hb_gtRealod() function which unloads current GT driver
and loads given new one
+ added .prg function HB_GTRELOAD( <cGtName> ) -> <lSuccess>
This function allow to switch active GT driver at run time.
It can be also used to simulate removed HB_NOSTARTUPWINDOW()
functionality. F.e.:
REQUEST HB_GT_WVT
REQUEST HB_GT_NUL_DEFAULT
proc main()
// do some initializations...
hb_gtReload( "WVT" )
// rest of code...
return
Please remember that some GTs may refuse initialization due to
missing required resources and instead of return FALSE they can
interrupt program with internal error, just like at application
startup so it's not guarantied that this function always returns.

; NOTE: This looks like a hack to add FLX_WAIT flag
for locks app-wide, and on Windows systems only.
IMO we should not have such hacks in core, or if
this is really important it should support all
possible platforms.
It also has a low-level function equivalent,
which is missing from hbapifs.h. There is no
reference to these function in any Harbour or

* harbour/source/rtl/filesys.c
+ added new functions: hb_fsExtName(), hb_fsReadAt(), hb_fsWriteAt(),
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.

* 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

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

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

+ 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

+ 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.

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.

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.
