This is merely technical, as it would need some hacks in the make system to push through HB_LEGACY_OFF to pptable.c generation. If someone wants to deal with this, even better. * include/hbstdgen.ch * Added #undef __FILE__. * include/hbsetup.ch * Minor.	2009-02-10 01:27:54 +00:00
Viktor Szakats	3ac4e62591	2008-11-01 08:45 UTC+0200 Viktor Szakats (harbour.01 syenar hu) ... * include/hbextern.ch * common.mak * source/rtl/Makefile + source/rtl/hbi18n.c + Added basic/low level i18n functions: __I18N_SAVE( cFileName | nHandle, aSortedTable [, cComment ] ) => lSuccess __I18N_LOAD( cFileName | nHandle ) => trs __I18N_GETTEXT( @cText, trs ) => NIL ; NOTE: These were originally based on Giancarlo Niccolai's work in xhb, but everything was completely reworked, fixed, internals removed, made portable, lighter, shorter and probably quicker. The used file format is incompatible, slightly smaller and portable. ; NOTE: The internal format of 'trs' (loaded translation) is also different. For minimal memory/speed overhead, I've choosen a one dimensional array, as opposed to the original two dimensional (like the input aSortedTable array). ; TODO: Higher level functions to handle selecting a default language, loading files automatically, possibly caching multiple loaded language translations in memory and providing a high level HB_I18N_GETTEXT() function. We may also readd a low-level function to create 'trs' from a memory object instead of loading it from the disk. We should in any case make the higher level the lightest and less app specific as possible. * include/hbver.ch * source/rtl/version.c * utils/hbtest/rt_str.prg * ChangeLog ! Fixed returning bit width. * Reworked hb_version() parameter values as follows: (also fixed some differences between docs here in the previous entry and actual code) HB_VERSION_HARBOUR (was: HB_V_HARBOUR ) HB_VERSION_COMPILER (was: HB_V_COMPILER ) HB_VERSION_MAJOR (was: HB_V_MAJOR ) HB_VERSION_MINOR (was: HB_V_MINOR ) HB_VERSION_MICRO (was: HB_V_REV ) HB_VERSION_STATUS (was: HB_V_STATUS ) HB_VERSION_REVISION (was: HB_V_COUNT ) HB_VERSION_BLD_DATE_STR (was: HB_V_DATE_TIME ) HB_VERSION_BLD_DATE (was: HB_V_DATE ) HB_VERSION_BLD_TIME (was: HB_V_TIME ) HB_VERSION_PCODE_VER (was: HB_V_PCODE ) HB_VERSION_PCODE_VER_STR (was: HB_V_PCODE_STR ) HB_VERSION_CHANGELOG_LAST (was: HB_V_CHANGELOG_LAST ) HB_VERSION_CHANGELOG_REV (was: HB_V_CHANGELOG_REV ) HB_VERSION_FLAG_PRG (was: HB_V_FLAG_HARBOUR ) HB_VERSION_FLAG_C (was: HB_V_FLAG_C ) HB_VERSION_FLAG_LINKER (was: HB_V_FLAG_LINKER ) HB_VERSION_BITWIDTH (was: HB_V_BITWIDTH ) HB_VERSION_ENDIANNESS (was: HB_V_ENDIANNESS ) This function makes deprecated following functions: - HB_COMPILER() => hb_version( HB_VERSION_COMPILER ) - HB_PCODEVER() => hb_version( HB_VERSION_PCODE_VER_STR ) - HB_BUILDDATE() => hb_version( HB_VERSION_BLD_DATE_STR ) and macros: - __ARCH16BIT__ - __ARCH32BIT__ - __ARCH64BIT__ - __LITTLE_ENDIAN__ - __BIG_ENDIAN__ - __PDP_ENDIAN__ - HB_VER_SVNID - HB_VER_CHLID - HB_VER_LENTRY - HB_VER_C_USR - HB_VER_L_USR - HB_VER_PRG_USR ; TOFIX: Some term anomalies regarding 'REVISION'. * source/vm/runner.c * Minor formatting and added "s_" prefix to static var.	2008-11-01 08:28:42 +00:00
Przemyslaw Czerpak	b9e2e7b6f0	2008-10-13 20:21 UTC+0200 Przemyslaw Czerpak (druzus/at/priv.onet.pl) ... * 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.	2008-10-13 18:21:42 +00:00

Dedicated hb_set*() functions should be used instead. + added new function: BOOL hb_setSetItem( HB_set_enum set_specifier, PHB_ITEM pItem ) which allow to change some set by 3-rd party code. TODO: not all SETs can be changed yet - if someone have a while then please add code for missing ones. * harbour/include/set.ch * harbour/include/hbset.h + added _SET_CODEPAGE which works like _SET_LANGUAGE giving common interface * harbour/include/hbsetup.h + added HB_CODEPAGE_DEFAULT which works like HB_LANG_DEFAULT * harbour/source/vm/hvm.c ! fixed builds which uses non EN lang or code page modules by forcing linking the chosen ones * harbour/include/hbstack.h * harbour/source/vm/estack.c * harbour/include/hbapicdp.h * harbour/source/rtl/cdpapi.c - removed global code page variable: hb_cdp_page and moved code page settings to HVM stack + added new function hb_cdpID() which returns current code page character ID + added new functions hb_vmCDP() and hb_vmSetCDP() to get/set active for given thread code page structure * harbour/include/hbstack.h * harbour/source/vm/estack.c * harbour/include/hbapilng.h * harbour/source/rtl/langapi.c + moved lang setting to HVM stack + added new functions hb_vmLang() and hb_vmSetLang() to get/set active for given thread language module * harbour/include/hbvmpub.h * harbour/include/hbstack.h * harbour/include/hbapi.h * harbour/source/vm/estack.c * harbour/source/vm/dynsym.c * harbour/source/vm/itemapi.c * harbour/source/vm/memvars.c * changed memvar handles for HB_HANDLE to void * which is directly casted to PHB_ITEM - new memvar references * changed HB_DYNS declarations for MT mode. In MT mode HB_DYNS does not contain area and memvar handles which are moved to thread local HVM stack + added array for thread local memvar and area handles to HVM stack % eliminated global continues array with all memvars and detached locals % changed HB_IT_MEMVAR to use pointers to HB_ITEM directly - it resolve synchronization problems in MT mode and should also improve the speed and reduce memory usage. It should be well visible in applications which uses lot of detached locals. - removed hb_memvarsInit() and hb_memvarsFree() - they are not necessary now because we do not longer use array with all allocated memvars and detached local and private stack initialization is made automatically + added internal functions hb_dynsymGetMemvar()/hb_dynsymSetMemvar() + added hb_memvarGetValueBySym() for debugger * moved PRIVATE variable stack to HVM stack * eliminated all static variables in memvars module * harbour/include/hbstack.h * harbour/source/vm/estack.c * harbour/source/rtl/fserror.c * moved IO errors to HVM stack + added special IO error handling which works without HVM stack It allows to use hb_fs*() functions without allocated stack by 3-rd party threads. * harbour/source/rtl/filesys.c * moved hb_fsCurDir() to HVM stack with special handling to work with HVM stack like IO errors * harbour/source/rdd/workarea.c * allocated RDD node array in bigger peaces to reduce later RT reallocations in MT mode. If user want to add dynamically more then 64 RDDs then it should synchronize this operation himself. * harbour/source/rdd/wacore.c * moved WA list, current WA, default RDD and neteer() flag to HVM stack * harbour/include/hbdefs.h - removed HB_HANDLE declaration * harbour/include/hbapi.h - removed HB_VALUE structure - it's not longer used due to different memvar handling * updated hb_struMemvar to new memvar handling * replaced hb_vmIsLocalRef() and hb_memvarsIsMemvarRef() with hb_vmIsStackRef() which respect multiple stack and new memvar and static structures and location in GC mark pass. * harbour/include/hbstack.h * harbour/source/vm/estack.c * harbour/source/vm/hvm.c + added support for thread specific data located on HVM stack Now it's possible to allocate static variables which are local to thread. Such variables are allocated on HVM stack and automatically destroyed. To declare new TSD variable use: HB_TSD_NEW( <name>, <size>, <init>, <destruct> ) <name> - name of variable which holds TSD handler <size> - size of TSD are which has to be allocated <init> - init function, executed when new TSD is allocated by thread (thread access given TSD 1-st time). This function receives void * pointer to allocated area. <destruct> - destructor function executed when HVM stack is destroyed f.e.: static HB_TSD_NEW( s_scrData, sizeof( HB_SCRDATA ), NULL, hb_xSaveRestRelease ); To initialize dynamically allocated TSD variable use: HB_TSD_INIT( <name>, <size>, <init>, <destruct> ) Pointer to TSD can be accessed using hb_stackGetTSD( &<name> ) where <name> is name of variable which holds TSD handler, f.e.: PHB_SCRDATA pScrData = ( PHB_SCRDATA ) hb_stackGetTSD( &s_scrData ); See source/rtl/xsavescr.c as an example It's also possible to test if data has been already allocated for current thread by: hb_stackTestTSD( &<name> ) => pData it works like hb_stackGetTSD() but return NULL if current thread data has not been allocated yet. * harbour/include/hbstack.h * harbour/source/vm/estack.c * changed hb_stack location to thread local storage in MT mode + added functions and macros to access/assign new HVM stack members + changed garbage collection mark functions to work with multiple stacks, thread local static and memvar variables * harbour/source/rtl/xsavescr.c * use TSD data for screen buffer to make __XSAVESCREEN()/__XRESTSCREEN() thread independent * harbour/source/rtl/idle.c * use TSD data for idle task settings and codeblocks - removed hb_idleShutDown() - it's not longer necessary * harbour/source/rtl/setkey.c * use TSD data for allocated keys to make SETKEY() thread independent * harbour/source/rtl/math.c * moved math error handler, math error block, math error mode and math error structure to TSD * harbour/source/rtl/errorapi.c * moved error handler, error block, error launch counter and DOS error value to TSD * harbour/source/rtl/inkey.c * moved inkey "before" and "after" blocks to TSD * harbour/source/rdd/hsx/hsx.c * moved HSX handles array to TSD * harbour/include/hbapigt.h * harbour/source/rtl/console.c - removed hb_setkeyInit() and hb_setkeyExit() - they are not longer necessary, allocated resources will be freed by TSD destructor function * harbour/include/hbapi.h * harbour/source/rtl/console.c * removed hb_conXSaveRestRelease() - it's not longer necessary, allocated resources will be freed by TSD destructor function * harbour/source/vm/macro.c * moved s_macroFlags to TSD * harbour/source/rtl/accept.c * moved accept buffer to TSD * harbour/include/hbcomp.h * harbour/include/hbcompdf.h * harbour/include/hbxvm.h * harbour/source/compiler/hbmain.c * harbour/source/compiler/hbfix.c * harbour/source/compiler/hbpcode.c * harbour/source/compiler/hbdead.c * harbour/source/compiler/complex.c * harbour/source/compiler/genc.c * harbour/source/compiler/gencc.c * harbour/source/compiler/hbopt.c * harbour/source/compiler/hblbl.c * harbour/source/compiler/hbstripl.c * harbour/source/compiler/harbour.y * harbour/source/compiler/harbour.yyc * harbour/source/compiler/harbour.yyh * harbour/source/vm/hvm.c + added new PCODE HB_P_THREADSTATICS + added support for static variables which are local to thread: THREAD STATIC <varname [:= <exp>], ...> They work like normal static variables but each thread operates on its own copy. * added protection against possible double call to hb_xfree() It can happen due to wrong marking expressions as used by bison and executing destructors after our free code when syntax error appear. * harbour/source/rtl/perfuncs.prg * harbour/source/rtl/menuto.prg * harbour/source/rtl/getlist.prg * harbour/source/rtl/readvar.prg * harbour/source/rtl/text.prg * use THREAD STATIC variables to make above code MT safe * harbour/include/hbgtcore.h * harbour/source/rtl/hbgtcore.c + added hb_gt_BaseFree() which will release current GT pointer locked by hb_gt_Base() function. This function will be used to optional automatic GT access synchronization when threads share the same GT. * harbour/source/rtl/gtapi.c * harbour/source/rtl/inkeyapi.c * harbour/source/rtl/mouseapi.c * harbour/contrib/hbct/ctwin.c * free GT pointer by hb_gt_BaseFree() TODO: CTWIN is not MT safe yet - it will be updated together with core GT when we add multi window interface for thread with own console window. * harbour/bin/hb-func.sh * harbour/config/linux/gcc.cf + added rt lib to Linux builds * harbour/bin/postinst.sh * create MT safe version of FM stat library: fmmt * harbour/bin/pack_src.sh + added support for ZIP packing * harbour/include/hbapi.h * harbour/include/hbvm.h * harbour/source/vm/hvm.c + added hb_vmThreadInit()/hb_vmThreadQuit() functions - they initialize HVM for calling thread so it can execute .prg code and call HVM functions. They can be used by 3-rd party code threads. + added hb_vmUnlock()/hb_vmLock() functions which informs that thread will not operate on HVM structures for some time allowing to execute single thread only processes like GC. + added hb_vmThreadQuitRequest() which sends stop request to given thread + added hb_vmWaitForThreads() which stops main thread execution waiting for other threads + added hb_vmSuspendThreads() and hb_vmResumeThreads() used be GC to stop all HVM threads before mark/swap scan + added linked list of HVM stacks + added hb_vmTerminateThreads() used by main HVM thread in QUIT state * moved EXIT procedures execution from QUIT request to HVM QUIT state in MT mode. It may effects some non structural code which tries to access private variables in EXIT functions but it's much cleaner and understandable for user. Please remember that we guaranties that ALWAYS code in BEGIN SEQUENCE is _always_ executed even after HVM QUIT request just like destructs. Personally I think that we should move EXIT procedures execution also in ST mode. * changed startup and cleanup code for new internal structures * changes startup and cleanup code for MT mode % removed some redundant HB_ITEM type settings ! eliminated non MT safe code which was using reference counters without protection * harbour/common.mak * harbour/source/vm/Makefile + harbour/include/hbthread.h + harbour/source/vm/thread.c + added C level functions to manage threads and synchronization objects See hbthread.h for detail description. They are based on PTHREAD API and PTHREAD documentation can be used as reference. I intentionally keep this list small for easier multiplatform porting. Now they have been implemented for PTHREADS (POSIX threads supported by many different OSes), MS-Win32/64 and OS2. The OS2 version is not tested at all. I do not even know if it can be compiled so please make tests. I used Internet resources and some part of xHarbour code as documentation for OS2 MT API. It should be quite easy to add other platforms if necessary. Harbour core code needs non recursive mutexes, conditional variables and TLS for one pointer. If platforms does not support conditional variables (f.e. MS-Win or OS2) then they can be emulated using multistate semaphores. + added .prg functions to manage threads and synchronization objects: hb_threadStart( <@sStart()> | <bStart> [, <params,...> ] ) -> <pThID> hb_threadJoin( <pThID> [, @<xRetCode> ] ) -> <lOK> hb_threadDetach( <pThID> ) -> <lOK> hb_threadQuitRequest( <pThID> ) -> <lOK> hb_threadWaitForAll() -> NIL hb_mutexCreate() -> <pMtx> hb_mutexLock( <pMtx> [, <nTimeOut> ] ) -> <lLocked> hb_mutexUnlock( <pMtx> ) -> <lOK> hb_mutexNotify( <pMtx> [, <xVal>] ) -> NIL hb_mutexNotifyAll( <pMtx> [, <xVal>] ) -> NIL hb_mutexSubscribe( <pMtx>, [ <nTimeOut> ] [, @<xSubscribed> ] ) -> <lSubscribed> hb_mutexSubscribeNow( <pMtx>, [ <nTimeOut> ] [, @<xSubscribed> ] ) -> <lSubscribed> The function list should give similar to xHarbour API but they are not exactly the same and except of hb_mutex*() functions which should replicate xHarbour behavior. + harbour/source/vm/vmmt + harbour/source/vm/vmmt/Makefile + added hbvmmt library to GNU make builds. Non GNU make builds should be updated. * harbour/contrib/hbct/pos1.c * harbour/contrib/gtwvg/gtwvg.c * harbour/contrib/rddads/ads1.c * harbour/contrib/hbmisc/spd.c * harbour/contrib/hbbmcdx/bmdbfcdx.c * harbour/contrib/examples/rdddbt/dbfdbt1.c * harbour/source/vm/runner.c * harbour/source/vm/itemapi.c * harbour/source/vm/hvm.c * harbour/source/rtl/console.c * harbour/source/rtl/strcase.c * harbour/source/rtl/spfiles.c * harbour/source/rtl/defpath.c * harbour/source/rtl/hbgtcore.c * harbour/source/rtl/dateshb.c * harbour/source/rtl/mlcfunc.c * harbour/source/rtl/fstemp.c * harbour/source/rtl/is.c * harbour/source/rtl/setcolor.c * harbour/source/rtl/errorint.c * harbour/source/rtl/transfrm.c * harbour/source/rtl/dates.c * harbour/source/rtl/filesys.c * harbour/source/rtl/gtdos/gtdos.c * harbour/source/rtl/gtwin/gtwin.c * harbour/source/rtl/gtwvt/gtwvt.c * harbour/source/rtl/gtxwc/gtxwc.c * harbour/source/rtl/gttrm/gttrm.c * harbour/source/rtl/gtpca/gtpca.c * harbour/source/rtl/gtcgi/gtcgi.c * harbour/source/rtl/gtcrs/gtcrs.c * harbour/source/rtl/gtstd/gtstd.c * harbour/source/rtl/gtsln/gtsln.c * harbour/source/rtl/gtsln/gtsln.h * harbour/source/rdd/dbf1.c * harbour/source/rdd/sdf1.c * harbour/source/rdd/delim1.c * harbour/source/rdd/dbcmd.c * harbour/source/rdd/hbdbsort.c * harbour/source/rdd/workarea.c * harbour/source/rdd/dbffpt/dbffpt1.c * harbour/source/rdd/dbfcdx/dbfcdx1.c * harbour/source/rdd/dbfntx/dbfntx1.c * harbour/source/rdd/hsx/hsx.c * harbour/source/rdd/hbsix/sxfname.c * use API functions instead of direct accessing to hb_cdp_page or hb_set * harbour/source/rtl/fstemp.c * harbour/source/rtl/fssize.c * harbour/source/rtl/hbffind.c * harbour/source/rtl/filesys.c * encapsulate potentially slow IO operation inside hb_vmUnlock()/hb_vmLock() calls to allow other thread GC activation * harbour/contrib/hbnf/fttext.c ! fixed casting * harbour/contrib/gtwvg/gtwvg.h - removed #include <comctl32.h> - my MinGW and MinGW/CE instalations do not have them. If it exists in some newer ones then it has to be covered by #if version checking. * harbour/source/vm/dynsym.c - removed hb_dynsymLog() and hb_dynsymMemvarHandle() * modified code to be MT safe and improved speed of some operations * added MUEXT protection for global dynamic table access * harbour/include/hbapi.h * harbour/source/vm/garbage.c * changed to work with MT HVM * changed to work with new memvar structures and thread local static and memvar variables * added MUEXT protection for linked block lists + added parameter to hb_gcCollectAll() which will force GC activation in MT mode by temporary suspending all executed threads. + added logical parameter to HB_GCALL() functions which is passed to hb_gcCollectAll() * harbour/source/vm/fm.c * added MUEXT protection for FM statistic module * added MT protection for reference counters. For platforms which supports atomic incrmenetation/decrementation (f.e. Interlocked*() functions in MS-Win) such operations are used. For other it's MUTEX protection. It gives MT safe readonly access for HVM complex variables without user synchronization. The MUTEX protection can cause some speed overhead so it's good to define MT safe version of HB_ATOM_INC()/HB_ATOM_DEC() in hbthread.h if given platform has them. Now they are defined only for Windows. For other platforms We can define can define them in assembler for some most popular CPUs in the future. * harbour/source/vm/classes.c * changed class definition array. Now it keeps pointers to class structures. * In MT mode allocated at HVM startup big enough array for class definitions to avoid later RT reallocations. It effectively eliminates MUTEX synchronization for class structure access. * protect by MUTEX code for new class creation * harbour/source/debug/dbgentry.c * eliminated hbvmopt.h and direct accessing to HVM structures * harbour/source/rtl/gtclip.c * protect with MUTEX access to internal clipboard data * harbour/source/rdd/nulsys/nulsys.c + added hb_rddCloseAll() + harbour/tests/mt + harbour/tests/mt/mttest01.prg + harbour/tests/mt/mttest02.prg + harbour/tests/mt/mttest03.prg + harbour/tests/mt/mttest04.prg + harbour/tests/mt/mttest05.prg + 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.	2008-09-13 16:53:45 +00:00

Now Harbour should work with signed and unsigned char without any problems. To other developers: please remember that when you are using 'char' as 8 bytes signed integer then it's a bug. Always explicitly use: 'signed char' in such case. On some platforms it's not possible to set default type for 'char' so if you hardcode that 'char' is signed or unsigned somewhere then code will not be portable. Chen if you will find a while to also rebuild Harbour with BCC and -K switch to make some tests with CG then I'll be thankful.	2006-12-08 05:03:58 +00:00
Przemyslaw Czerpak	1202be4471	2006-09-22 23:00 UTC+0200 Przemyslaw Czerpak (druzus/at/priv.onet.pl) ... * harbour/include/hbclass.ch * harbour/include/hbvm.h * harbour/source/rtl/tclass.prg * harbour/source/vm/classes.c * harbour/source/vm/hvm.c ! fixed bug in real codeblock scoping which was exploited by dictionary resizing * changed ACCESS messages to ASSIGN ones when object item reference is created for proper READONLY scope checking. The reference to object variable can be created only when caller has sufficient ASSIGN privileges. + added FRIEND CLASS and FRIEND FUNCTION support. It's enough to add class definition: FRIEND CLASS <classFunc1> [, <classFuncN> ] and/or: FRIEND FUNCTION <FuncName1> [, <FuncNameN> ] and all methods of given class or given function will be able to access private variables. Warning!!! Friends cannot access overloaded non virtual methods. This feature is available _ONLY_ for real class members. + added MODULE FRIENDLY to class definition. It causes that all other functions and classes defined in the same .prg module will have friend privileges. In such way works xHarbour and there is now way to disable this "feature" what is IMHO bug. In Harbour programmer has to explicitly enable it (until he will not change / add new preprocessor rule and set it as default ;-)). Syntax: CREATE CLASS .... MODULE FRIENDLY ... END CLASS * harbour/source/vm/proc.c * harbour/source/vm/runner.c * updated function symbols processing * harbour/source/compiler/harbour.c * added note in hb_compOptimizeFrames() about exceeding maximum number of local variables (255). We should add new pcode(s) HB_P_LARGE[V]FRAME or generate compile time error. * harbour/source/vm/macro.c % minor optimizations	2006-09-22 21:02:17 +00:00
Viktor Szakats	076082265a	2006-09-05 15:51 UTC+0100 Viktor Szakats (viktor.szakats syenar.hu) ... * harbour/include/hbset.h * harbour/include/set.ch * harbour/source/pp/pptable.c * harbour/source/rtl/set.c + Added Set( _SET_DEFEXTENSIONS, <logical: .T./.F.> ) Default value is .T. (CA-Cl*pper compatible). If set to .F., Harbour runtime/RDD code will never attempt to add a default extension to the filename arguments. Commands/functions where this setting makes a difference are: - SET ALTERNATE TO / Set( _SET_ALTFILE_, ... ) - SET PRINTER TO / Set( _SET_PRINTFILE_, ... ) - Set( _SET_EXTRAFILE, ... ) - SAVE TO / __mvSave() - RESTORE FROM / __mvRestore() - LABEL FORM - REPORT FORM - COPY TO ... DELIMITED - COPY TO ... SDF - LIST / __dbList() - USE / dbUseArea() - dbCreate() - SET INDEX TO / ordListAdd() (not yet implemented) - __HRBLOAD(), __HRBRUN() ; Notes: - From now on, it possible to create/load files using the above functions/commands which have no extension. This might be desirable in a few platform and/or situations. For example on Win32, it's possible to directly print to a shared Windows printer queue, using these commands: lOldValue := Set( _SET_DEFEXTENSIONS, .F. ) SET PRINTER TO \\myserver\myprinter Set( _SET_DEFEXTENSIONS, lOldValue ) Or, it is possible to open a dbf file which has no extension: dbUseArea(.T., NIL, "dbf_filename_with_no_extension", "w_DATA", .F., .F.) - Compiler is (of course) not affected by this setting. - Preprocessor (PP) lib flavour is not affected by this setting. - Support is not full in the RDD code yet. * harbour/source/rdd/dbf1.c * harbour/source/rdd/dblist.prg * harbour/source/rdd/delim1.c * harbour/source/rdd/sdf1.c * harbour/source/rtl/tlabel.prg * harbour/source/rtl/treport.prg * harbour/source/rtl/set.c * harbour/source/vm/memvars.c * harbour/source/vm/runner.c + Honoring _SET_DEFEXTENSIONS setting all over the code.	2006-09-08 12:47:27 +00:00

So I only count the main things: ! cleand the code (no more warning messages under Linux and GCC and DOS OpenWatcom) - some of them were real bugs ! cleaned all endian dependend code I've found - now Harbour can be compiled on LITLE and BIG endian machines - for some other like PDP ENDIAN it's enough to define proper macros in hbdefs.h + added macros for to get/put values in chosen byte order: HB_GET_LE_[U]INT{16,24,32,64}( pPtr ) HB_GET_BE_[U]INT{16,24,32,64}( pPtr ) HB_PUT_LE_[U]INT{16,24,32,64}( pPtr, nVal ) HB_PUT_BE_[U]INT{16,24,32,64}( pPtr, nVal ) + added macro HB_CAST_BYTE_NUMBERS_OFF which disables casting in HB_{GET|PUT}_{LE|BE}_* macros - it's necessary for some platforms like ALPHA DEC. ! cleaned the code for 64bit machines * changed all parameters in hb_date* functions (day, month, year, week) from LONG to int - it doesn't change binary compatibility for 32bit machines but can cause troubles with compiling the old source + changed HB_IT_LONG type to HB_LONG which is mapped to long long by default for 32 bit machines. + change HB_IT_INTEGER to be real 'int' C type not 'short int' + added HB_IS_NUMINT() macro + added hb_parnll, hb_stornll, hb_retnll, hbretnlllen, hb_itemPutNLL, hb_itemPutNLLLen, hb_itemGetNLL which operates on LONGLONG + added hb_parnint, hb_stornint, hb_retnint, hb_retnintlen, hb_itemPutNInt, hb_itemPutNIntLen, hb_itemGetNInt which operates on HB_LONG + added HB_PUSHLONGLONG pcode + changed compiler and optimizer to use HB_LONG numbers and reduce conversion from to double which may damage the 64bit number. + common functions for string to number conversions for compiler, RTL and RDD to reduce problems with differ FL values for the same number: hb_compStrToNum(), hb_valStrnToNum(), hb_strToNum(), hb_strnToNum() + common function hb_numRoun() which uses exactly the same algorithms as string to number conversion for the same reason - please keep this functions together. + hack inside hb_numRound() similar to the one used by CL5.3 + hb_numInt() which uses uses the same hack as hb_numRound() + rewritten number to string conversion + some new string manipulation functions hb_strncpy(), hb_strncat(), ... They works differ the the C one - always set 0 at the end, the buffer has to be n+1 bytes length, the n is total size of buffer not the left free space. ! cleaned some code which operates on ASCIIZ string to avoid potential buffer overflow + updated RDD code - it's the first part - in few days I plan to change workarea structure in both projects - it will break any 3rd party RDDs so they have to be updated. I want to add SUPERTABLE into workarea to allow creating new RDD on-line. ! cleaned the bugs with negating integers - on most machines (like x86) the integers are not 0 symmetric - it means that x = -x does not work for {INT,LONG,LONGLONG}_MIN (hb_vmNegate, ABS()) + cleaned error messages to be Clipper compatible. + updated build process for .DEB packages - now hb* scripts and shared libs are created by standard make install * added new .prg #defines: __PLATFORM__<cPlatfrom>, __ARCH{16|32|64}BIT__, __LITTLE_ENDIAN__|__BIG_ENDIAN__|__PDP_ENDIAN__ !!! cPlatfrom can have lower letters (for xHarbour compatibility) If you do not like it please change it. * others ...	2004-10-11 20:44:30 +00:00
