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.

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

(there was a mixed situation here, but there's no need to mark any HB_ functions as extensions, as it's obvious by their name. So as a rule, no HB_ prefixed function should ever be marked as HB_EXTENSION anymore.) ! Fixed some inconsistencies in HB_EXTENSION between hbextern.ch and actual sources. * source/rtl/tgetlist.prg * One HB_EXTENSION changed to !HB_C52_STRICT because it was guarding a bugfix rather than a real extension. * source/rtl/gui.prg * _GetNumCol() is now always strictly compatible. NOTE added about sloppy C5.3 behaviour. * source/rtl/inkey.c * contrib/xhb/xhb.ch * contrib/xhb/xhbfunc.c ! __KEYBOARD() xhb hidden parameter extension moved to xhb lib.

AT() extra parameters handled when HB_EXTENSION is on (was !HB_C52_STRICT). (The first extra parameter is XPP and Flagship compatible. The three parameter version of this function is called AT3() in CAVO.) ! TRIM()/RTRIM() extra parameters handled on compiler level when HB_EXTENSION is on (default). ! FILE() parameter check turned off in compiler. (to be C5.x compatible) * source/rtl/alert.prg ! ALERT() Harbour extended parameter (1st parameter type) is now guarded with HB_EXTENSION instead of HB_C52_STRICT. * source/rtl/gete.c ! GETE[NV]() Harbour extended parameter guarded with HB_EXTENSION. * source/vm/proc.c ! PROCFILE() Harbour extended parameter guarded with HB_EXTENSION. * source/rtl/mlcfunc.c ! Harbour extended parameters for MEMOLINE()/MLCOUNT()/ MLPOS()/MLCTOPOS()/MPOSTOLC() are now guarded with HB_EXTENSION (instead of HB_C52_STRICT). It seems to be possible to specify custom EOLs for all these functions. (Maybe simple automatic Unix/Win EOL style handling would be better here) * source/vm/memvars.c ! Guarded Harbour extension in __MVRESTORE() with HB_EXTENSION. ; After this cleanup: - HB_EXTENSION is marking extra features living inside existing C5.x functions or classes, or Harbour extension functions not complying with the HB_ prefix rule (we have six such functions in RDD). If there are more extended parameters in Harbour pls mark them with HB_EXTENSION too. - HB_C52_STRICT is guarding bugfixes compared to C5.x. - No HB_ functions are guarded with HB_EXTENSION anymore. - We'd pbly need to review each HB_EXTENSIONs to check whether they are safe or not. - A list of HB_EXTENSIONs: - MLCOUNT() MEMOLINE() MLPOS() MLCPOS() MPOSTOLC() - 5th and up can specify custom EOLs. - ALERT() - 1st parameter type can be any type in Harbour, char only in C5.x - SET FUNCTION TO __SETFUNCTION - 2nd parameter can be numeric or array of numeric in Harbour. - SETKEY() - 3rd codeblock parameter ("isactive" block) - SAVESCREEN() - 5th parameter: lNoCheck (?) RESTSCREEN() - 6th parameter: lNoCheck (?) - AT() - 3rd and 4th parameters to set search range. 3rd parameter is also supported by XPP and FS. Results in compiler error in C5.x. (CAVO uses AT2() and AT3() for extended versions.) - TRIM() RTRIM() - 2nd parameter is an extension regarding space trimming mode. Results in compiler error in C5.x. - ALLTRIM() - 2nd parameter is an extension regarding space trimming mode. - GETE() GETENV() - 2nd parameter specifies a default value. Can be found in HB_GETENV(). - PROCFILE() - 1st parameter is a Harbour extension. Undocumented function in C5.x. The extension looks similar to the one found in Flagship. - __MVRESTORE() - 3rd/4th parameters are Harbour extensions to set variable name mask. Redirected from the internal 5.x function named __MRESTORE(). - DB*() - cRDD, nConnection, cCodePage extra parameters in many DB*() functions. TOFIX: None of them is marked as HB_EXTENSION. - SET()s - These are not marked as HB_EXTENSION. - ? - Is there anything else?	2007-10-16 11:04:51 +00:00

In such case hb_dynsymNew() checks if linker updated function addresses and if yes then remove unnecessary HB_FS_LOCAL flag. In such case works GCC (but not MinGW and DJGPP), OpwenWatcom for Linux, DOS, Windows (and probably for OS2), POCC, XCC (with /FORCE:MULTIPLE linker switch) and some other linkers I haven't tested. Otherwise (two different functions with the same name linked and each accessible from different symbol, f.e. BCC32, MinGW, DJGPP) it accept multiple HB_FS_LOCAL for dynamically loaded modules (.hrb, .dll, .so, .dyn, ...) if HVM also accepted it (for future KEEP_LOCAL_FUNC HB_LIBLOAD()/__HBRLOAD() parameter). For statically linked modules it overloads one of the functions when HB_OVERLOAD_MULTIPLE_FUNC macro is set (now by default to make tests with different linkers). I left detail description in source code of hb_dynsymNew() in source/vm/dynsym.c. I hope it will also help Ron in recent xHarbour modifications - AFAIK it's sth what he tires to do. Anyhow please remember that that dirty overloading any symbols by linker is very bad idea and in such case you have big chance that wrong binaries will be created so the most preferable choice is eliminating such situations and not using linker switches like -Wl,--allow-multiple-definition or /FORCE:MULTIPLE + harbour/tests/multifnc + harbour/tests/multifnc/t0.prg + harbour/tests/multifnc/t1.prg + harbour/tests/multifnc/t2.prg + harbour/tests/multifnc/Makefile + added test code for results of dirty overloaded functions.

Of course PHB_DYNS address is also perfectly good hash value and in classes code can be used but it does not guaranties that all messages will cover well whole 16bit area used as message pool without dynamic bucket size modification. * harbour/source/vm/classes.c * changed hashing method. Now it uses really unique base hash key values which can cover whole 16 bit area so mathematically it's not be possible to break it by any combination of method names as long as our dynamic symbol table will be limited to 2^16 symbols. It still consumes more memory then necessary and I'll change it in the future but it's much less then before. The BUCKET size is smaller (4) and all calculations are done only with bit shifts so it should be also faster. * use ULONG instead of USHORT to calculate maximum number of methods to avoid possible overflow problems if it reach 2^16 (rather impossible in normal application - it will have to create more then 2^15 symbols) ! some other fixes and code cleanup * harbour/source/vm/hvm.c * minor modifications	2006-09-01 21:28:02 +00:00

This function works in similar way to dbInfo() in RDD. The GTI_* definitions are taken from xHarbour "as is" and they should be cleaned - not all functionality are supported in Harbour and some others should be implemented in differ way then in xHarbour. + harbour/include/hbgtcore.h * harbour/include/hbapigt.h * new GTAPI hbgtcore.h file should not be included by user code it's only for internal use in GT drivers * HB_inkey_enum changed to int - this is bit field not enumerated type. Many of C/C++ compilers forbid bit operations on enum types and forcing it by casting which finally exceeds the enum range is defined as bug because it may badly interacts with some compiler optimizations * harbour/include/hbapi.h * harbour/include/hbapicdp.h * harbour/include/hbapierr.h * harbour/include/hbapifs.h * harbour/include/hbapiitm.h * harbour/include/hbapilng.h * harbour/include/hbapirdd.h * harbour/include/hbdate.h * harbour/include/hbdefs.h * harbour/include/hbinit.h * harbour/include/hbpcode.h * harbour/include/hbrdddbf.h * harbour/include/hbset.h * harbour/include/hbstack.h * harbour/include/hbvm.h * harbour/include/hbvmopt.h * harbour/include/hbvmpub.h * separated internal and external API. Now the definitions for internal HVM structures and functions are excluded by default they could be enabled if user include hbvmopt.h before other header files. Such operation should be done _ONLY_ by core code - if 3-rd party developers make sth like that then it's for their own risk and such code may stop to work with next Harbour versions. Without hbvmopt.h the internal structures like HB_ITEM, HB_DYNS, ... are mapped to 'void' so there is no way to access their members so we can modify them in the future without afford for 3-rd party code. There is one small exception 'type' should be the first member for HB_ITEM structure because I used a small ugly hack in HB_IS_*() macros with castin PHB_ITEM to HB_TYPE* - it works without speed overhead but if you think that it will be better/cleaner to not use such tricks then it's enough to change HB_ITEM_TYPE() definitions in hbvmpub.h - see note. * cleared the usage of HB_EXPORT - to avoid problems with some C/C++ compilers we agreed that the only one common way of using HB_EXPORT is adding it ad begining of declaration - please keep this convention in the future. + added new functions: hb_extIsObject(), hb_codeblockId(), hb_idleSleep(), hb_fsGetOsHandle(), hb_dynsymFindSymbol(), hb_dynsymGetSymbol(), hb_dynsymSymbol(), hb_dynsymName(), hb_dynsymMemvarHandle(), hb_dynsymAreaHandle(), hb_dynsymSetAreaHandle() * changed hb_arrayClone() declaration to: PHB_ITEM hb_arrayClone( PHB_ITEM pArray ) * changed hb_arrayFromParams() declaration to: PHB_ITEM hb_arrayFromParams( int iLevel ) The previous version needed a pointer to stack relocatable area so any stack resizing could cause GPF. * harbour/include/inkey.ch * added definitions for extended mouse keys/events and some key combinations * harbour/source/codepage/uc1250.c * harbour/source/codepage/uc1251.c * harbour/source/codepage/uc1253.c * harbour/source/codepage/uc1257.c * harbour/source/codepage/uc737.c * harbour/source/codepage/uc850.c * harbour/source/codepage/uc852.c * harbour/source/codepage/uc866.c * harbour/source/codepage/uc88591b.c * harbour/source/codepage/uc8859_1.c * harbour/source/codepage/uc8859_2.c * harbour/source/codepage/uc8859_5.c * harbour/source/codepage/uckoi8.c * harbour/source/codepage/uckoi8u.c * harbour/source/codepage/ucmaz.c * updated unicode values for characters in rabge 1-31 to keep DOS compatibility * harbour/source/common/expropt1.c * harbour/source/common/hbarch.c * harbour/source/common/hbdate.c * harbour/source/common/hbstr.c * harbour/source/common/hbver.c * keep HB_EXPORT at the beginning of function declaration * harbour/include/hbpcode.h * harbour/include/hbcomp.h * harbour/source/compiler/harbour.c * harbour/source/compiler/harbour.y * harbour/source/compiler/hbfix.c + harbour/source/compiler/hbdead.c * harbour/source/compiler/hbpcode.c + harbour/source/compiler/hbstripl.c % 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. * harbour/source/rdd/dbcmd.c * harbour/source/rdd/dbf1.c * harbour/source/rdd/rddord.prg * harbour/source/rdd/workarea.c * harbour/source/rdd/dbfcdx/dbfcdx1.c * harbour/source/rdd/dbffpt/dbffpt1.c * harbour/source/rdd/dbfntx/dbfntx1.c * harbour/source/rdd/nulsys/nulsys.c * synced with my modifications in xHarbour * updated for API modifications * harbour/source/rtl/Makefile + added gtsys.c, gtfunc.c, hbgtcore.c * harbour/source/rtl/accept.c * harbour/source/rtl/alert.prg * harbour/source/rtl/cdpapi.c * harbour/source/rtl/console.c * harbour/source/rtl/dates.c * harbour/source/rtl/do.c * harbour/source/rtl/errorapi.c * harbour/source/rtl/errorsys.prg * harbour/source/rtl/file.c * harbour/source/rtl/fserror.c * harbour/source/rtl/fstemp.c * harbour/source/rtl/hbffind.c * harbour/source/rtl/idle.c * harbour/source/rtl/math.c * harbour/source/rtl/oldclear.c * harbour/source/rtl/strmatch.c * harbour/source/rtl/strpeek.c * harbour/source/rtl/valtype.c * harbour/source/rtl/xsavescr.c * updated for API modifications * cleaned some compiler warnings * harbour/source/rtl/filesys.c + added hb_fsGetOsHandle() * updated for API modifications * harbour/source/rtl/gt.c * harbour/source/rtl/gtapi.c * harbour/source/rtl/gtapiu.c + harbour/source/rtl/gtfunc.c + harbour/source/rtl/gtsys.c + harbour/source/rtl/hbgtcore.c * harbour/source/rtl/inkey.c * harbour/source/rtl/maxrow.c * harbour/source/rtl/mouseapi.c * harbour/source/rtl/setcolor.c * harbour/source/rtl/setposbs.c * harbour/source/rtl/shadow.c * new GT API code * harbour/source/rtl/saverest.c * changed default behavior in SEVESCREEN/RESTSCREEN with parameters out of screen range to be Clipper compatible.

This file is included with proper path in binaries created by make_rpm.sh and make_tgz.sh Ryszard I've removed some of your extensions which are no longer necessary and some other (keyboard sequence redefinition) should be done in a little bit differ way.

Added support for extended mouse keys (middle button and wheel). * harbour/source/rtl/gtdos/Makefile * harbour/source/rtl/gtdos/gtdos.c - harbour/source/rtl/gtdos/mousedos.c * rewritten for new GT API Fixed some small problems, finished mouse code which for DJGPP is fully Clipper compatible with real mouse SAVE/RESTORE code. For other compilers it should be updated depending on memory model and used DPMI driver (if any). * harbour/source/rtl/gtos2/Makefile * harbour/source/rtl/gtos2/gtos2.c - harbour/source/rtl/gtos2/mouseos2.c * rewritten for new GT API Fixed some problems and finished the mouse code. Please test it - I made all modifications without OS2 and I was not able to make any test. I'm interesting in information if it works and the speed difference - f.e. results from tests/vidtest.prg run with previous and current version. * harbour/source/rtl/gtpca/Makefile * harbour/source/rtl/gtpca/gtpca.c - harbour/source/rtl/gtpca/kbdos2.gcc - harbour/source/rtl/gtpca/mousepca.c * rewritten for new GT API and finished so now it's full functional GT driver I'm interesting in keyboard sequences used by PC-ANSI drivers in DOS so it will be possible to implement also support for extended keys input. * harbour/source/rtl/gtsln/Makefile * harbour/source/rtl/gtsln/gtsln.c + harbour/source/rtl/gtsln/gtsln.h * harbour/source/rtl/gtsln/kbsln.c * harbour/source/rtl/gtsln/keytrans.c * harbour/source/rtl/gtsln/mousesln.c * rewritten for new GT API basing on current xHarbour code 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) Added support for extended mouse keys (middle button and wheel). * harbour/source/rtl/gtstd/Makefile * harbour/source/rtl/gtstd/gtstd.c - harbour/source/rtl/gtstd/mousestd.c * rewritten for new GT API Now it can work as full screen GT driver redrawing the previous screen contents from internal GT core buffers. I run with this GT some of my programs and they work quite well ;-) of course without colors. * harbour/source/rtl/gtwin/Makefile * harbour/source/rtl/gtwin/gtwin.c - harbour/source/rtl/gtwin/mousewin.c * updated for new GT API + harbour/source/rtl/gtxwc/Makefile + harbour/source/rtl/gtxwc/gtxwc.c + harbour/source/rtl/gtxwc/gtxwc.h * new XWindow Console GT driver based on my and Giancarlo Niccolai 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. * harbour/source/vm/arrays.c * updated for API modifications + added hb_arrayId(), * changed hb_arrayClone() declaration to: HB_EXPORT PHB_ITEM hb_arrayClone( PHB_ITEM pSrcArray ) * changed hb_arrayFromParams() declaration to: PHB_ITEM hb_arrayFromParams( int iLevel ) * harbour/source/vm/arrayshb.c * updated for API modifications + added new parameter iLevel to function HB_APARAMS() * harbour/source/vm/classes.c * harbour/source/vm/cmdarg.c * harbour/source/vm/dynlibhb.c * harbour/source/vm/estack.c * harbour/source/vm/fm.c * harbour/source/vm/garbage.c * harbour/source/vm/maindll.c * harbour/source/vm/maindllh.c * harbour/source/vm/maindllp.c * harbour/source/vm/mainstd.c * harbour/source/vm/mainwin.c * harbour/source/vm/memvars.c * harbour/source/vm/pcount.c * harbour/source/vm/proc.c * updated for API modifications * harbour/source/vm/codebloc.c * updated for API modifications + added hb_codeblockId() * harbour/source/vm/dynsym.c * updated for API modifications + added new functions: hb_dynsymFindSymbol(), hb_dynsymGetSymbol(), hb_dynsymSymbol(), hb_dynsymName(), hb_dynsymMemvarHandle(), hb_dynsymAreaHandle(), hb_dynsymSetAreaHandle() * harbour/source/vm/eval.c * updated for API modifications * call hb_vmPushState()/hb_vmPopState() in hb_itemDo()/hb_itemDoC() functions - it's necessary to make HVM reentrant safe. * harbour/source/vm/extend.c * updated for API modifications + added hb_extIsObject() similar to existing hb_extIsArray() * harbour/source/vm/hvm.c * updated for API modifications + added new functions: hb_vmPushState(), hb_vmPopState() which save/restore HVM state (the top stack value which can be processed and return item and maybe sth else in the future) making HVM ready for reentrant. * harbour/source/vm/itemapi.c * updated for API modifications + added new function: HB_EXPORT PHB_SYMB hb_itemGetSymbol( PHB_ITEM pItem ); ! fixed bug in hb_itemPutNInt() * harbour/tests/Makefile * harbour/utils/hbdoc/Makefile * harbour/utils/hbextern/Makefile * harbour/utils/hbmake/Makefile * harbour/utils/hbrun/Makefile * harbour/utils/hbtest/Makefile - removed badly added: dbfntx, dbfcdx, dbffpt, hbsix libraries. 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. *** Please updated non GNU make files ***	2006-02-04 16:16:48 +00:00
