Przemyslaw Czerpak	26a11bd859	2009-03-21 16:07 UTC+0100 Przemyslaw Czerpak (druzus/at/priv.onet.pl) ... * harbour/bin/hb-func.sh ! restored default optimization flag (-O3) in hb* scripts * harbour/harbour.spec ! fixed recent modification * harbour/contrib/rddads/ads1.c * harbour/contrib/rddads/adsfunc.c * harbour/contrib/hbmisc/strfmt.c * harbour/contrib/hbcrypt/sha1.c ! fixed wrongly used C reference operator * harbour/contrib/hbwin/win_prn2.c * harbour/contrib/hbwin/wapi_commctrl.c * harbour/source/vm/maindllp.c ! fixes for unicode builds * harbour/include/std.ch + added SET TIME FORMAT [TO] <f> * harbour/include/set.ch * harbour/include/hbset.h * harbour/source/vm/set.c + added _SET_TIMEFORMAT The folowing modifiers are supported: hh - hours mm - minutes ss - seconds fff - fraction part of seconds p - 1-st letter from PM / AM signature. When used time is shown in 12 hour format otherwise 24 hour format is used ex: Set( __SET_TIMEFORMAT, "hh:mm pm" ) default _SET_TIMEFORMAT value is "hh:mm:ss:fff" + added C function: char * hb_setGetTimeFormat( void ); * harbour/include/hbpp.h * harbour/source/pp/ppcore.c + added support for timestamp constant values in the form: t"YYYY-MM-DD HH:MM:SS.fff" The exact accepted timestamp pattern is is: YYYY-MM-DD [H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM] i.e.: tValue := t"2009-03-21 5:31:45.437 PM" or: YYYY-MM-DDT[H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM] with literal "T" as date and time part delimiters (XML timestamp format), i.e.: tValue := t"2009-03-21T17:31:45.437" The folowing characters can be used as date delimiters: "-", "/", "." if PM or AM is used HH is in range < 1 : 12 > otherwise in range < 0 : 23 > * harbour/source/compiler/complex.c * harbour/source/compiler/harbour.y * harbour/source/compiler/harbour.yyc * harbour/source/compiler/harbour.yyh + added support for t"YYYY-MM-DD HH:MM:SS.fff" time stamp constant to compiler + added support for VFP datetime constant values: { ^ [ YYYY-MM-DD [,] ] [ HH[:MM[:SS][.FFF]] [AM|PM] ] } The following characters can be used as date delimiters: "-", "/". Dot "." as date delimiter is not supported. There is no limit on number of characters in YYYY, MM, DD, HH, MM, SS, FFF parts. Important is only their value. This is the format in semi PP notation: { ^ <YEAR> <sep:/-> <MONTH> <sep:/-> <DAY> [[<sep2:,>] [ <HOUR> [ : <MIN> [ : <SEC> [ . <FRAQ> ] ] ] [AM|PP] ] } In practice it allows to also parse xHarbour datetime constant values with compatible conditions though xHarbour support onlu "/" as date delimiter. NOTE: there is one important difference to VFP and xHarbour in decoding above format. In VFP and xHarbour when date part is missing then it's set by default to: 1899-12-30 so this code: { ^ 12:00 } gived the same results as: { ^ 1899/12/30 12:00 } Harbour does not set any default date value when timestamp constant value contains only time part. If you want we can change it for strict VFP compatiblity. Now this extension is enabled by default for testing. In the future it will be probably covered by HB_COMPAT_FOXPRO macro. * harbour/source/macro/macro.yyc * harbour/source/macro/macro.y * harbour/source/macro/macro.yyh * harbour/source/macro/macrolex.c + added support for t"YYYY-MM-DD HH:MM:SS.fff" time stamp constant to macro compiler * harbour/include/hbmacro.h * harbour/source/vm/macro.c + added new function: void hb_macroGenPushTimeStamp( LONG lDate, LONG lTime, HB_COMP_DECL ); * harbour/include/hberrors.h * harbour/source/compiler/hbgenerr.c + added new compile time error: "Invalid timestamp constant '%s'" * harbour/source/compiler/cmdcheck.c * use Harbour API timestamp functions instead of calling system functions * harbour/include/hbpcode.h * harbour/source/compiler/hbfix.c * harbour/source/compiler/hbpcode.c * harbour/source/compiler/hbdead.c * harbour/source/compiler/genc.c * harbour/source/compiler/gencc.c * harbour/source/compiler/hblbl.c * harbour/source/compiler/hbstripl.c * harbour/source/compiler/hbopt.c + added new PCODE HB_P_PUSHTIMESTAMP (replaced one unused PCODE value) to store timestamp constant values in the PCODE * harbour/include/hbcomp.h * harbour/source/compiler/hbmain.c + added new function: void hb_compGenPushTimeStamp( LONG lDate, LONG lTime, HB_COMP_DECL ); * harbour/include/hbexprop.h * harbour/source/common/expropt1.c + added new C functions: HB_EXPR_PTR hb_compExprNewTimeStamp( LONG, LONG, HB_COMP_DECL ); * harbour/include/hbexprb.c * harbour/include/hbcompdf.h * harbour/source/common/expropt2.c + added timestamp expressions support + added compile time optimization for timestamp expressions * updated function optimization for timestamp expressions * harbour/include/hbdate.h * harbour/source/common/hbdate.c * changed hb_dateMilliSeconds() to return UTC julian timestamp in milliseconds * changed existing seconds, time and timestamp functions to operate on common OS specific functions to eliminate possible problems with different OS time counters + added new functions to operates on time and timestamp values.

When date and timestamp values are used in <, <=, >, >=, = operations then VM compares only date part in both values. When date and timestamp values are used in == operation then VM compares date part in both values and then check if time part of timestamp value is 0. + added support for timestamp values in + and - math operations. The following rules are used in timestamp arithmetic: <t> + <t> => <t> <t> - <t> => <n> <t> + <n> => <t> <n> + <t> => <t> <t> - <n> => <t> <d> + <t> => <t> <t> + <d> => <t> <d> - <t> => <n> <t> - <d> => <n> When number is result or argument of timestamp operation then the its integer part is a number of day and fractional part is the time. * harbour/source/rtl/dateshb.c + added new .prg functions to mange date and timestamp values: HB_DATETIME() -> <tTimeStamp> HB_CTOD( <cDate> [, <cDateFormat> ] ) -> <dDate> HB_DTOC( <dDate> [, <cDateFormat> ] ) -> <cDate> HB_NTOT( <nValue> ) -> <tTimeStamp> HB_TTON( <tTimeStamp> ) -> <nValue> HB_TTOC( <tTimeStamp>, [ <cDateFormat> ] [, <cTimeFormat> ] ) -> <cTimeStamp> HB_CTOT( <cTimeStamp>, [ <cDateFormat> ] [, <cTimeFormat> ] ) -> <tTimeStamp> HB_TTOS( <tTimeStamp> ) -> <cYYYYMMDDHHMMSSFFF> HB_STOT( <cDateTime> ) -> <tTimeStamp> <cDateTime> should be in one of the above form: - "YYYYMMDDHHMMSSFFF" - "YYYYMMDDHHMMSSFF" - "YYYYMMDDHHMMSSF" - "YYYYMMDDHHMMSS" - "YYYYMMDDHHMM" - "YYYYMMDDHH" - "YYYYMMDD" - "HHMMSSFFF" - "HHMMSSF" - "HHMMSS" - "HHMM" - "HH" Important is number of digits. HB_TSTOSTR( <tTimeStamp> ) -> <cTimeStamp> // YYYY-MM-DD HH:MM:SS.fff HB_STRTOTS( <cTimeStamp> ) -> <tTimeStamp> <cTimeStamp> should be in one of the above form: YYYY-MM-DD [H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM] YYYY-MM-DDT[H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM] The folowing characters can be used as date delimiters: "-", "/", "."

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.

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. For similar functionality inside Harbour pls use HB_KEYPUT(). __KEYBOARD is now 100% C5.x compatible. * source/rtl/setfunc.prg * __SetFunction() extension now uses HB_KEYPUT() instead of __KEYBOARD() extended parameters. * source/compiler/hbfunchk.c * source/rtl/at.c ! 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

It's not such flexible like curses or slang base drivers because instead of using termcap/terminfo databases to extract terminal capabilities it uses some hard coded sequences for few terminals (now Linux, ANSI, XTERM) but it should cover users requests in 95% of cases. Terminals I tested are quite well supported (GTTRM works even better then GTCRS or GTSLN and is much faster in full screen mode - 2-4 times). I noticed that most terminal emulators works much better with GTTRM then with GTCRS or GTSLN due to limited list of used escape sequences so some minor differences in each terminal implementation are not noticeable. GTTRM automatically detects ISO/UTF8 terminal mode and chose valid output what should also help *nix users. Now I would like to ask BSD and MacOSX users to test GTTRM in these systems with pure text console and XWindow terminal emulators. I'm interesting in any problems you may found. * harbour/source/vm/hvm.c + added protection for possible GPF caused by wrong .prg code * harbour/source/vm/maindllp.c % store function addreses in static variables to improved execution speed + added support for compilers which does not use "_" as function prefix + added support for using with harbour*.dll * harbour/source/vm/memvars.c + added new method of detaching enumerators and array item references covered by HB_COMPAT_XHB macro. xHarbour does not work in such way but the final results are similar. * harbour/source/vm/dynlibhb.c + added protection against passing wrong pointer items to HB_LIB*() functions * harbour/source/common/reserved.c * cleaned warning * harbour/bin/hb-func.sh * harbour/config/hpux/global.cf * harbour/config/darwin/global.cf * harbour/config/linux/global.cf * harbour/config/sunos/global.cf * harbour/config/bsd/global.cf + added GTTRM to library list	2007-06-20 19:07:37 +00:00

Now it's used by memvars code to keep/update PRIVATE variables stack pointers.

This should not be necessary but we are not Clipper compatible here and this is work around for difference in our TYPE() implementation. Clipper for: ? TYPE("VAR:=1") create PUBLIC variable VAR when [x]Harbour PRIVATE one. Should we try to make it Clipper compatible? The above should fix problems reported with memvars. We are not 100% Clipper compatible but unlike in Clipper we cannot break VM internals using some operation on references to memvars and detached locals and/or RELEASE.../ CLEAR MEMORY. This modifications should be intensively tested. If you will find any problems with current code please inform me. I'd like to hear your opinions about memvars created by TYPE() (see above). Should we change it? It may not be very easy operation - we will have to change macro compiler and add new PCODE for that.	2006-08-18 23:12:38 +00:00

In fact it was not guarantied even before my modifications. You coule be sure only that the allocated item will not be complex one and you can safely pass pointer to it to any other functions. It allow to clean a little bit some code and remove redundant and repeated setting HB_IT_NIL for allocated items. Now using hb_stackPush() can be necessary only in some very seldom cases. hb_stackAllocItem() allocates new item and returns pointer to this item. After some code cleaning hb_stackPush() is not used by core Harbour code at all so if you have it in your sources then please check if you should not update them. * harbour/source/rdd/usrrdd/usrrdd.c * use hb_vmPushNil() instead of hb_stackPush() * harbour/source/vm/arrays.c * changed hb_arrayNew() to be safe for automatic GC activation * some minor speed improvement * harbour/source/vm/codebloc.c * changed hb_codeblockNew() and hb_codeblockMacroNew() to be safe for automatic GC activation * harbour/source/vm/debug.c * use only stack function/macros instead of direct accessing hb_stack I hope that I haven't break anything. * harbour/source/vm/hvm.c ! use hb_stackAllocItem() instead of hb_stackTopItem() to make our HVM reentrant safe. This modifications also fixed some possible bugs which could be exploited by other modules which have to execute .prg code - f.e. in RDD when relation codeblock has to be executed to position record in fieldget/fieldput operations. * harbour/source/vm/itemapi.c * harbour/source/vm/memvars.c * use hb_stackAllocItem() The above modifications finish stack usage and making our HVM reentrant safe. There is only one thing which have to be fixed yet. It's HVM support for xbase++ syntax in things like: func(&<paramList>), aVal[&<indexList>], {&<itemList>} To fix it we will have to change PCODE generated by compiler and replace some PCODEs used for current code by the new one. I will wait with this modifications for Ryszard. With the above exception now we are ready to implement destructors, add automatic GC and begin to work on MT though before that I'd like to clean the RT error support. Please carefully check if all is correct. It was modification in core code and even small typo can break whole application.	2006-07-04 11:27:48 +00:00

support for pure PCODE function without any machine code * use stack function/macros instead of direct accessing HB_STACK members * separated profiler code * some code cleaning * harbour/source/vm/codebloc.c + added USHORT usLen parameter to hb_codeblockMacroNew() - when sets to non 0 value it informs that PCODE should be copied to dynamically allocated buffer. * updated to use GC counters - removed hb_codeblockDelete() function. * changed hb_codeblockDeleteGarbage() to be safe for recursive call - removed restoring statics base in hb_codeblockEvaluate() * harbour/source/vm/debug.c * cleaned and optimized some code * harbour/source/vm/dynlibhb.c + added support for loading and unloading dynamic libraries with PCODE + added support for dynamic libraries in Linux (.so) + added HB_LIBERROR() -

They are internal Harbour VM functions and covered by internal API macro. Should not be used by 3-rd party code because we may change them in the future or even remove. * harbour/source/vm/garbage.c + added hb_gcRefInc(), hb_gcRefDec(), hb_gcRefFree(), hb_gcRefCount() functions. These are also internal function which corresponds to the above hb_x*() ones. * changed Step 3 of GC pass and execution of clean-up function to be safe for recursive calls and additional activity. Ryszard see my note and s_pDeletedBlock + added GC inspected HB_IT_POINTER items. * harbour/source/vm/hvm.c * separated profiler code * separated class code from HVM + added support for loading and unloading libraries with PCODE modules + added support for pure PCODE functions + added support for string item resizing and preallocating string buffer + added some new multipcode functions for -gc3 optimization + added hb_vmProcessSymbolsExt(), hb_vmRegisterSymbols(), hb_vmFreeSymbols(), hb_vmBeginSymbolGroup(), hb_vmInitSymbolGroup(), hb_vmExitSymbolGroup() * changed hb_vmProcessSymbols() to return address of register symbol table. For normal code it's the same address as given in parameter so it does not break backward binary compatibility. + use new code for operator overloading * changed FOR EACH to dynamically check iteration scope in hb_vmEnumNext()/hb_vmEnumPrev() and remove max number of iteration stored on HVM stack * temporary use hb_itemUnRefOnce() instead of hb_itemUnRefRefer() as workaround for possible GPF. I'd like Ryszard will chose the final version * harbour/source/vm/itemapi.c + added support for preallocating string buffer size + added hb_itemUnShareString() and hb_itemReSizeString() * updated string items to use counters allocated with each memory block by xh_xgrab()/hb_xalloc() * updated codeblock and array items to use GC reference counters + added GC inspected HB_IT_POINTER items. * generate RT error in hb_itemUnreOnce() for enumerator items out of scope + added hb_itemPutPtrGC() * harbour/source/vm/macro.c * use pDynSym->pSymbol->value.pFunPtr instead of pDynSym->pFunPtr * harbour/source/vm/maindllp.c * updated usage of hb_vmProcessSymbols() * added hb_vmProcessSymbolsExt() * harbour/source/vm/memvars.c + added hb_memvarGetItem() - removed hb_memvarValueDecGarbageRef() * harbour/source/vm/proc.c + added #include "hbapicls.h" * harbour/source/vm/pvalue.c * do not access stack structure directly but use hb_stack*() functions (macros) * harbour/source/vm/runner.c * synced with xHarbour * harbour/utils/hbtest/rt_misc.prg * added overloading "=" operator. Now "==" and "=" can be overloaded with different methods All names I used for new functions/macros can be changed. Please look at it and if you will some better propositions then we can use it. hb_vmProcessSymbolsExt() is added but not used yet.	2006-06-14 11:21:26 +00:00
Przemyslaw Czerpak	68ceb7444c	2006-03-22 16:05 UTC+0100 Przemyslaw Czerpak (druzus/at/priv.onet.pl) ... * harbour/include/hbstack.h * harbour/source/vm/estack.c + added hb_stackDecrease( ULONG ) * harbour/include/hbxvm.h * harbour/source/vm/hvm.c + added hb_xvmArrayItemPush(), hb_xvmArrayItemPop(), hb_xvmMultByInt() * harbour/source/compiler/gencc.c % use hb_xvmArrayItemPush(), hb_xvmArrayItemPop(), hb_xvmMultByInt() If someone has time then it will be good to also add: hb_xvmDivByInt(), hb_xvmModulusInt(), hb_xvmPlusInt(), hb_xvmMinusInt() * harbour/source/vm/itemapi.c * use simple memcpy() in hb_itemSwap() - it's save in current HVM It could become unsafe if we add reference tracing or sth like that in the future but in such case we will have to also update hb_itemCopy() and hb_itemMove() so we can also update hb_itemSwap() * harbour/source/vm/asort.c * harbour/source/vm/classes.c * harbour/source/vm/memvars.c * harbour/source/vm/hvm.c * cleaned the code which created HB_ITEMs on C stack. Only three places have to be update yet and array/clodeblock creation little bit modified and we will be able add automatic GC activation in hb_xgrab() or hb_gcAlloc().	2006-03-22 15:14:21 +00:00
