Przemyslaw Czerpak	fa31aa6f70	2008-12-11 19:48 UTC+0100 Przemyslaw Czerpak (druzus/at/priv.onet.pl) ... * harbour/include/hbthread.h * harbour/source/vm/thread.c + added hb_atomic_set(), hb_atomic_get(), hb_atomic_inc() and hb_atomic_dec() functions which operates on HB_COUNTER or smaller type if it's necessary for some platforms which can be access/assign increment/decrement in MT safe atom operations. hb_atomic_dec() returns true if counter is 0 after decrementation * harbour/include/hbatomic.h ! fixed compilation in Linux and OpenWatcom * harbour/include/hbapiitm.h * harbour/source/rtl/itemseri.c + make hb_itemSerialize() and hb_itemDeserialize() public functions ! fixed serialization items with internal item references * harbour/source/vm/hvm.c * release memvars after closing RDDs * harbour/source/debug/dbgentry.c ! fixed buffer overflow reported by Rodrigo * harbour/source/vm/macro.c * harbour/source/compiler/hbmain.c * formatting * harbour/include/hbexprb.c ! fixed wrongly recognized functions with HB_I18N_ prefix as HB_I18N_GETTEXT() * harbour/include/hbapi.h * harbour/include/hbstack.h * harbour/include/hbthread.h * harbour/source/vm/estack.c * harbour/source/vm/thread.c * harbour/source/vm/hvm.c + added support for I18N in HVM. Each thread can have it's own i18n set. When new thread is created then it inherits i18n set from parent thread and both uses the same set (please remember about it if you will want to make some direct modifications on active i18n set internals). When thread change active i18n set then it effects only this thread and new threads which will be create later. It does not change i18n in other existing threads. + added functions to set/get pointer to active i18n set in HVM void * hb_vmI18N( void ) void hb_vmSetI18N( void * ) * harbour/include/hbapi.h * harbour/source/rtl/hbi18n.c + added i18n module. Now only for internal Harbour usage without support for optional switching to alternative implementations. I'll add such functionality later when I will work on native gettext support. The following public .prg functions has been added: HB_I18N_GETTEXT[_STRICT]( <cMsgID> [, <cContext> ] ) -> <cTranslatedMsgID> | <cMsgID> HB_I18N_NGETTEXT[_STRICT]( <nValue>, <cMsgID> | <acMsgID> ; [, <cContext> ] ) -> <cTranslatedMsgID> | <cMsgID> | <acMsgID>[ <nIndex> ] This is minimal support necessary for .prg code which has to exists in each i18n module working with Harbour. The following functions had been added as public C API: PHB_ITEM hb_i18n_gettext( PHB_ITEM pMsgID, PHB_ITEM pContext ) PHB_ITEM hb_i18n_ngettext( PHB_ITEM pNum, PHB_ITEM pMsgID, PHB_ITEM pContext ) The following functions had been added as private HVM C API: void hb_i18n_init( void ) void hb_i18n_exit( void ) void hb_i18n_release( void * cargo ) void * hb_i18n_alloc( void * cargo ) They have to be supported by alternative i18n modules The following functions has been added to manage Harbour i18n translations sets: HB_I18N_CREATE() -> <pI18N> Creates new empty I18N translation set HB_I18N_CODEPAGE( [<pI18N>,] [<cNewCP>], [<lBase>], [<lTranslate>] ) -> <cOldCP> Gets or sets Harbour codepage used by translation set <pI18N> - I18N translation set, if it's not given then currently active I18N set is used <cNewCP> - new CP ID. Must be linked with application <lBase> - when it's .T. then get/set base massages CP instead of translated massages CP <lTranslate> - if it's .T. then translate base (<lBase>==.T.) or final messages in I18N set from previous CP to given one. Base messages translation in synced with context ID translation. HB_I18N_PLURALFORM( [<pI18N>,] [<cNewForm>|<bNewForm>], [<lBase>] ) -> <cOldForm>|<bOldForm> Gets or sets plural form used for final or base messages <pI18N> - I18N translation set, if it's not given then currently active I18N set is used <cNewForm> - language ID of plural form, f.e.: "EN", "PL", "LT". Now only three above are supported. Please add rules for other languages to source/rtl/hbi18n.c. <bNewForm> - codeblock used to calculate plural form indexes. can be used instead of character representation but it's not storred in serialized I18N set <lBase> - when it's .T. then get/set base massages plural form instead of translated massages one. HB_I18N_DESCRIPTION( [<pI18N>,] [<cNewDescription>] ) -> <cOldDescription> Gets or sets translation set description. After serialization up to 32 bytes is stored in header which can be easy used to determinate type of translation file. <pI18N> - I18N translation set, if it's not given then currently active I18N set is used <cNewDescription> - new description HB_I18N_ADDTEXT( <pI18N>, <cMsgID>, <cTrans> | <acTrans> [, <cContext> ] ) -> NIL Adds new message with translation to i18n translation set <pI18N> - I18N translation set <cMsgID> - original message <cTrans> - translated message <acTrans> - array with translated messages used for plural forms <cContext> - message context HB_I18N_SET( [ <pI18N> | NIL ] ) -> <lActive> Sets given I18N translation set as default one used by HB_I18N_[N]GETTEXT[_STRICT]() functions or remove translation set for calling thread when passed parameter is NIL <pI18N> - I18N translation set Returns logical value which is .T. when i18n set is active HB_I18N_SAVETABLE( [<pI18N>] ) -> <cTable> Returns I18N translation as string item which can be stored in file or database <pI18N> - I18N translation set, if it's not given then currently active I18N set is used HB_I18N_RESTORETABLE( <cTable> ) -> <pI18N> | NIL Restores I18N translation set from strin item. <cTable> - I18N translation set in string representation On success it returns new <pI18N> set otherwise NIL if <cTable> is not valid item created by HB_I18N_SAVETABLE() or it's corrupted. HB_I18N_HEADERSIZE() -> <nHeaderSize> Returns size of header used by i18n serialized version HB_I18N_CHEK( <cTable> | <cHeader> [, @<cDescription> ] ) -> <lValid> <cTable> - i18n translation set serialized by HB_I18N_SAVETABLE <cHeader> - header of i18n translation set ( LEFT( <cTable>, HB_I18N_HEADERSIZE() ) <cDescription> - optional parameter passed by reference where will be sored i18n translation set description extracted from valid header Returns logical value indicating if given table or header is valid serialized by HB_I18N_SAVETABLE() data. It does not decode the table though it validates size and control sums. These functions are optional and some future alternative implementations may not support all of them and/or may provide some other functions. + added unofficial .prg function __I18N_HASHTABLE() which allows to access hash table used by i18n translation set or create new translation set with given hash table. It's helper functions for developers which will work on Harbour i18n tools and should not be used by Harbour users. Unlike original gettext Harbour allows to use language with many plural forms as base one. In such case programmer should activate at application startup default i18n translation set with base plural form valid for base application language, f.e. by: pI18N := hb_i18n_create() hb_i18n_pluralForm( pI18N, <cLangID> | <bForm>, .t. ) hb_i18n_set( pI18N ) .prg code example: #xtranslate _( <x,...> ) => hb_i18n_gettext_strict( <x> ) #xtranslate _N( <x,...> ) => hb_i18n_ngettext_strict( <x> ) proc main() local pI18N, i pI18N := hb_i18n_create() hb_i18n_pluralForm( pI18N, "PL", .t. ) hb_i18n_set( pI18N ) for i := 0 to 30 ? i, _N( i, {"grosz", "grosze", "groszy"} ) if i > 0 .and. i % 10 == 0 wait endif next return In .pot files created during compilation by Harbour with -j option for above code we have the following entries for message with plural forms: msgid "grosz" msgid_plural "grosze" msgid_plural2 "groszy" msgstr[0] "" The msgid_plural2 (and others if language has more plural forms) is Harbour extension which is not gettext compatible. The above implementation is base version but should be fully functional. Now we will need functions to safe/read i18n files and tools to mange .pot files: merge them, edit translations, create final binary i18n translation sets. Because we are using gettext compatible .pot files then for some of such jobs we can use original gettext tools but we need at least function which will create translation set from one or more .pot files. We should also agree some default localization(s) for files containing translated data, their name convention and environment variable(s) to set default language. It's not strictly necessary and each user can have his own implementation but it would help in adding new translations by final users to any Harbour application which will respect them. We can use LANG envvar to extract preferred language and use the same path as executed application looking for files <appname>-<lang>.hil files though it may create some problems for OSes which support only 8.3 file names so we can also define that HB_I18N envvar has higher priority and points to expected translation file. * harbour/include/hbextern.ch - removed old __i18n_*() functions + added current i18n functions	2008-12-11 18:47:46 +00:00
Przemyslaw Czerpak	16f9a67e9f	2008-12-02 11:27 UTC+0100 Przemyslaw Czerpak (druzus/at/priv.onet.pl) ... * harbour/contrib/xhb/Makefile * harbour/contrib/xhb/common.mak + harbour/contrib/xhb/xhbarr.c + added aSplice(), aRemove() and aMerge() functions - code borrowed from xHarbour by Ron Pinkas. ! fixed GPF trap in these functions * harbour/contrib/xhb/xhbfunc.c + added CSTR() * harbour/contrib/xhb/hbcompat.ch ! changed name of xHarbour include files - they where changed few months ago and now they are the same as in Harbour. To xHarbour users: please update hbcompat.ch in xHarbour CVS * harbour/contrib/xhb/filestat.c ! fixed UNICODE compilation * harbour/contrib/xhb/hblognet.prg * harbour/contrib/xhb/hblog.prg * formatting * harbour/contrib/hbnf/tempfile.prg ! do not use HB_ISBYREF() .prg function - this function does not exist in Harbour and does not work correctly in xHarbour * harbour/include/hbapiitm.h * harbour/source/vm/macro.c * harbour/source/vm/codebloc.c * harbour/source/vm/hashes.c * harbour/source/vm/garbage.c * harbour/source/vm/itemapi.c * harbour/source/vm/memvars.c * cleanup * harbour/contrib/gtwvg/Makefile ! fixed typo * harbour/contrib/gtwvg/hbgtwvg.ch * added new line at the end of file and changed non ANSI C // comments to /* */ - this file is included by C code too. * harbour/contrib/gtwvg/wvgwin.c * harbour/contrib/gtwvg/wincallb.c * pacified some warnings and fixed possible access to uninitialized data * harbour/source/compiler/harbour.y * harbour/source/compiler/harbour.yyc ! fixed possible double freeing of memory blocks in #line directives TOMERGE[1.0] * harbour/common.mak * harbour/source/compiler/hbmain.c + harbour/source/compiler/compi18n.c * moved hb_compI18n*() functions to separate file covered by GPL with Harbour exception - Thank to Mindaugas * harbour/include/hbcomp.h * harbour/include/hbcompdf.h * harbour/include/hbexpra.c * harbour/include/hbexprop.h * harbour/include/hbexprb.c * harbour/source/common/expropt1.c * harbour/source/compiler/Makefile * harbour/source/compiler/ppcomp.c * added support for plural forms: hb_i18n_ngettext[_noop|_strict]( <nExp>, <cText> | <acText> ; [, <cContext> ) <acText> is accepted only as array of literal strings even if _strict suffix is missing - if it's a problem then we can change it. hb_i18n_ngettext_noop() is reduced only when it has valid parameters The default plural index expression used for reduction at compile time is: iif( <nExp> == 1, 1, 2 ) If second parameter of hb_i18n_ngettext_noop() is <cText> or <acText> length is 1 then it's reduced to <cText> or acText[1] else if second parameter is <acText> with more then 1 item then it's reduced to <acText>[ iif( <nExp> == 1, 1, 2 ) ] and if <nExp> is literal numeric expression is farther reduced to given array item. Otherwise is not reduced and warning is generated. The plural forms in .pot files are generated as: msgid "" msgid_plural "" msgid_plural2 "" [...] msgid_pluralN "" msgstr[0] "" Then real message ID is only msgid (with context if any) and msgid_plural* is used only for information. When the same msgid is used more then once in different hb_i18n_ngettext*() calls then plural messages are merged. Please remember that for strict gettext compatibility only two plural forms are allowed. * extended i18n warnings for simple types validation, f.e.: hb_i18n_gettext( .t. ) * do not generate empty .pot file when source code does not contain any hb_i18n_*() functions * store in .pot files references to real source file names with paths respecting #include directives * use hb_compIdentifierNew() to hash i18n messages at compile time ! fixed possible bad escape encoding of i18n strings + added support to control -j[01] flag using #pragma directive Before I'll begin to work on runtime support please test these modifications and inform me about problems you can see with the above version and missing functionality.	2008-12-02 10:26:51 +00:00

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.

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.

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

So, now this was renamed to hb_itemPutCLPtr(), and stub was added with the old name, and Harbour code was changed to use the new one. I've also added hb_itemPutCPtr2() as a version not requiring len parameter, the proper name would be hb_itemPutCPtr() for this, but we cannot use without breakin compatiblity. IMPORTANT: I'd strongly suggest all 3rd parties to update their code to use the call hb_itemPutCLPtr() instead of hb_itemPutCLPtr(). The final goal would be to have hb_itemPutCPtr() with two parameters instead of the hakish looking hb_itemPutCPtr2(). I'd welcome any opinions how to reach this goal. I didn't want to break compatiblity with 3rd parties this time, but IMO we may do it in 1.1, or even before 1.0. !

In most cases these functions can replace the xHarbour ones + added HB_DESERIALBEGIN() and HB_DESERIALIZE() functions covered by HB_COMPAT_XHB macro - this functions are only for compatibility with existing xHarbour code, In Harbour HB_DESERIALBEGIN() is dummy function which returns first parameter and HB_DESERIALNEXT() is a simple wrapper to HB_DESERIALIZE() so it's not necessary to use them. * harbour/source/rtl/hbinet.c * changed INET*() functions to HB_INET*() and enable them for default build + added INET*() functions wrappers covered by HB_COMPAT_XHB macro * harbour/source/rtl/hbrandom.c + added HB_RANDOMINT() - xHarbour compatible * harbour/source/rtl/len.c + added support for HASHes * harbour/source/rtl/valtype.c + added support for HASHes + added set of HB_IS*() functions - they are a little bit faster then calling VALTYPE( v ) == <cVal> - removed HB_ISBYREF() - this function cannot longer work, it was using a Clipper incompatible anomalies in passing variables by reference I fixed so it has to stop to work. If it will be realy necessary to implement HB_ISBYREF() function then please inform me - it will have to be done at compiler level or with some much deeper HVM stack checking. * harbour/source/vm/extend.c ! fixed hb_extIsArray() and hb_extIsObject() to work well with parameters passed by reference.

The TIP library was not tested at all. It can be compiled but I cannot say if it works - I hope that people familiar with it can make necessary test and fixes. It's also not the final version of low level HASH item code. I'm working on more efficient structure which uses binary tries but I cannot say when I'll finish it (maybe in this weekend or maybe in next year) so I committed working version now even if I'm not happy with overall performance (BTW not worser then in xHarbour)	2007-03-22 12:28:14 +00:00

Now we are supporting also some code which cannot be compiled by Clipper. % cleaned and improved the speed of printer redirecting in console code.

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

Only constant/read only variables are shared. In macro compiler HB_COMP is replaced by HB_MACRO. In source code I everywhere used to macros: HB_COMP_DECL and HB_COMP_PARAM which are equivalents of old HB_MACRO_DECL and HB_MACRO_PARAM definitions. We will only have to change compiler FATAL errors support to not execute exit() for non batch systems. * make macro compiler fully MT safe * removed not longer used definitions and variables ! add direct accessing to PP line number information - it fixes missing line numbers reported recently ! added generating .ppo files when tokens are teken directly by compiler - it fixes empty .ppo file problem ! clear hb_stack internall variables after removing hb_stack to avoid possible GPF if application still works and try to access unexsiting hb_stack ! do not allocate new memory block when final FM statistic report is generated - it fixes problem with GPF when application compiled with FM statistic exits and CLIPPER envvar is set. ! fixed memory leak hb_cmdargCheck() ! added to harbour.y symbol destructors - it should fixes memory leaks in syntax errors but it uses quite new bison feature which is not fully supported yet. Unfortunately it's also not MT safe and the destructors implementation in 1.875c does not respect %parse-param. Bison documentation says that it should so I hope it will be fixed soon (or maybe even already is in the newest bison versions) before I'll add multi context compilation support. If not then I will have to add some workaround. I can pass compiler context pointer inside YYSTYPE using hack in a lexer but it will force really huge number modifications in existing bison rules so probably it will be much easier to fix bison or write a small tool to update generated parser. * other modifications - the total size of patch is nearly 1MB and detail description will have to take me few days.	2006-11-23 18:57:54 +00:00

Now we should update all compiler functions to pass pointer to HB_COMP data structure where we should all current global variables. This structure as first member should have HB_CMPCOMMON structure which will hold common to compiler and macro compiler data. Ryszard I think you are the best person to define this structure. We have new lexer which is MT safe but please note that it has to be extensively tested so I would like to ask everybody to compile as much as possible different code and check if the final programs work as expected. Working on new code I removed some limitations existing in FLEX though not all. At the beginning I tried to replicate the exact FLEX behavior but I've found that in few places it does not work as it should so I begin to encode rules in a way which remove some limitations. In fact now it's much easier to control some things. I kept the FLEX code working and made all necessary modifications so it still can be used but keeping FLEX working cost us IMHO too much. It's not possible to introduce some improvements to grammar parser. All identifiers, keyword and macros returned by new lexer are converted to upper letters, do not have to be freed by hb_xfree() and is guarantied that will be always accessible. So from grammar file we can remove all hb_compIdentifierNew( hb_strupr($1), TRUE ) what should give noticeable speed improvement but will break the FLEX code. Ryszard and other you will have to decide if we will support FLEX in the future. We can also clean the code and remove most of other redundant hb_strupr() and hb_strdup() used in many places. BTW only one terminal symbol can be returned with lower letters: DOIDENT and I make it intentionally so it's possible to use: DO prog1 WITH "sth" on case sensitive file systems so this symbol should be cloned in upper cases as function symbol but used without modification as file name. It's current behavior but I'm not sure you will want to keep it. Maybe compiler switch to always convert file names created from DO <id> [WITH <params,...>] to lower cases will be better. Please think about it.	2006-11-21 02:29:33 +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
