* harbour/include/hbpp.h
* harbour/source/pp/hbpp.c
* harbour/source/pp/ppcore.c
* harbour/source/compiler/hbmain.c
+ added support for dynamically calculated #define results
! removed old code which was adding __FILE__ #define constant
It was not working correctly like in other compilers ignoring
#include
+ added __FILE__ and __LINE__ #define directives using dynamically
calculated results - now it works as expected respecting #include
directives and the implementation is local to PP without any hacks
in core compiler code.
* harbour/contrib/hbct/files.c
* added support for optional milliseconds part in HB_FSETDATETIME()/
HB_FGETDATETIME().
* harbour/source/rtl/philes.c
! minor fix in return value

* include/hbpp.h
* Minor rearrangement of previous state.
Still referencing HB_ISDIGIT() and HB_TOUPPER(), one time
each.
* contrib/xhb/hbxml.c
* isspace() -> HB_ISSPACE(). HB_ISSPACE() should be
revised in the future if Unicode is used, but until
then this is fine here.
* ChangeLog
* Marked one TODO as [CANCELLED].

* harbour/include/hbwmain.c
* pacified unused variable warning
* harbour/include/hbpp.h
* harbour/source/pp/ppcore.c
! do not report #if expression errors in #if PP directives when they are
in codedis activated by parent #if[def]/#elif/#else. It allows
to compiler code like:
#ifdef DEFINE
#if DEFINE >= 0x100
...
#endif
#endif
+ added logical expression reduction to not report #if expression errors
in code like:
#ifdef DEFINE && DEFINE >= 0x100
...
#endif
! fixed possible division by 0error in #if exporessions like #if 1 / 0
Now #if expression compiler error is generated
! restored some bit operators in #if directives wrongly disabled with
xHarbour stuff

* harbour/include/hbstack.h
* harbour/source/vm/estack.c
* moved from RTL to HVM
* eliminated hb_set global structure
* moved set structure to HVM stack
+ added internal function hb_setClone() which is used to create
copy of SET structure for child threads
* hidden HB_SET_STRUCT declaration - 3-rd part code must not access it
directly. 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

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/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

* 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 error handler, error block, error launch counter and DOS error
value to TSD
* harbour/source/rtl/inkey.c

* 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/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/include/hbgtcore.h
* harbour/source/rtl/hbgtcore.c
+ added hb_gt_BaseFree() which will release current GT pointer
locked by hb_gt_Base() function. This function will be used
to optional automatic GT access synchronization when threads
share the same GT.
* harbour/source/rtl/gtapi.c
* harbour/source/rtl/inkeyapi.c
* harbour/source/rtl/mouseapi.c
* harbour/contrib/hbct/ctwin.c
* free GT pointer by hb_gt_BaseFree()
TODO: CTWIN is not MT safe yet - it will be updated together
with core GT when we add multi window interface for
thread with own console window.
* harbour/bin/hb-func.sh
* harbour/config/linux/gcc.cf
+ added rt lib to Linux builds
* harbour/bin/postinst.sh
* create MT safe version of FM stat library: fmmt
* harbour/bin/pack_src.sh
+ added support for ZIP packing
* harbour/include/hbapi.h
* harbour/include/hbvm.h
* harbour/source/vm/hvm.c
+ added hb_vmThreadInit()/hb_vmThreadQuit() functions - they initialize
HVM for calling thread so it can execute .prg code and call HVM
functions. They can be used by 3-rd party code threads.
+ added hb_vmUnlock()/hb_vmLock() functions which informs that
thread will not operate on HVM structures for some time allowing
to execute single thread only processes like GC.
+ added hb_vmThreadQuitRequest() which sends stop request to given
thread
+ added hb_vmWaitForThreads() which stops main thread execution waiting
for other threads
+ added hb_vmSuspendThreads() and hb_vmResumeThreads() used be GC
to stop all HVM threads before mark/swap scan
+ added linked list of HVM stacks
+ added hb_vmTerminateThreads() used by main HVM thread in QUIT state
* moved EXIT procedures execution from QUIT request to HVM QUIT state
in MT mode. It may effects some non structural code which tries to
access private variables in EXIT functions but it's much cleaner
and understandable for user. Please remember that we guaranties
that ALWAYS code in BEGIN SEQUENCE is _always_ executed even after
HVM QUIT request just like destructs. Personally I think that we
should move EXIT procedures execution also in ST mode.
* changed startup and cleanup code for new internal structures
* changes startup and cleanup code for MT mode
% removed some redundant HB_ITEM type settings
! eliminated non MT safe code which was using reference counters
without protection
* harbour/common.mak
* harbour/source/vm/Makefile
+ harbour/include/hbthread.h
+ harbour/source/vm/thread.c
+ added C level functions to manage threads and synchronization objects
See hbthread.h for detail description. They are based on PTHREAD API
and PTHREAD documentation can be used as reference. I intentionally
keep this list small for easier multiplatform porting.
Now they have been implemented for PTHREADS (POSIX threads supported by
many different OSes), MS-Win32/64 and OS2. The OS2 version is not tested
at all. I do not even know if it can be compiled so please make tests.
I used Internet resources and some part of xHarbour code as documentation
for OS2 MT API. It should be quite easy to add other platforms if necessary.
Harbour core code needs non recursive mutexes, conditional variables and
TLS for one pointer. If platforms does not support conditional variables
(f.e. MS-Win or OS2) then they can be emulated using multistate semaphores.
+ added .prg functions to manage threads and synchronization objects:
hb_threadStart( <@sStart()> | <bStart> [, <params,...> ] ) -> <pThID>
hb_threadJoin( <pThID> [, @<xRetCode> ] ) -> <lOK>
hb_threadDetach( <pThID> ) -> <lOK>
hb_threadQuitRequest( <pThID> ) -> <lOK>
hb_threadWaitForAll() -> NIL
hb_mutexCreate() -> <pMtx>
hb_mutexLock( <pMtx> [, <nTimeOut> ] ) -> <lLocked>
hb_mutexUnlock( <pMtx> ) -> <lOK>
hb_mutexNotify( <pMtx> [, <xVal>] ) -> NIL
hb_mutexNotifyAll( <pMtx> [, <xVal>] ) -> NIL
hb_mutexSubscribe( <pMtx>, [ <nTimeOut> ] [, @<xSubscribed> ] ) -> <lSubscribed>
hb_mutexSubscribeNow( <pMtx>, [ <nTimeOut> ] [, @<xSubscribed> ] ) -> <lSubscribed>
The function list should give similar to xHarbour API but they are not exactly
the same and except of hb_mutex*() functions which should replicate xHarbour behavior.
+ harbour/source/vm/vmmt
+ harbour/source/vm/vmmt/Makefile
+ added hbvmmt library to GNU make builds.
Non GNU make builds should be updated.

* harbour/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

+ 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.

level instead of generating it locally.
; QUESTION: Should or shouldn't we change __HARBOUR__
to contain revision number too? (0x0100 -> 0x01000)
This would allow for a greater level of development
opportunities between minor revisions, more "agile"
development.

* harbour/utils/Makefile

+ harbour/utils/hbdot/Makefile
+ added hbdot utility program.
It's a "DOt Prompt" Console for the Harbour Language
Syntax: hbdot [<hrbfile[.prg]> [<parameters,...>]]
It should look and work in similar way to pp/xBaseScript
by Ron Pinkas but unlike xBaseScript is does not have preprocessor
or simulated runtime environment but simply uses Harbour pp and
compiler libraries to preprocess and compile commands. It means
that it supports all language constructions also statements, f.e.:
"for i:=1 to 10; ? i; next"
Additionally it can also compile and execute .prg files given as
first parameter just like hbrun.
Please test it. If it will work as expected then we can remove
'pp' (contrib/dot) from standard packages

+ added support for extended multiline codeblocks:
{ |<params,...>| <EOL>
<statement1>
...
<statementN>
return <val>
}
Such codeblocks allow nested definitions. They can also have their
own variable declarations (local, static, field, memvar, parameters,
private, public) and visibility of declared variables is similar to
nested function in Pascal but please note that there is one limitation
which exists also for normal codeblocks (Clipper compatible behavior):
internal codeblock local parameters and local variables cannot be
used in nested codeblocks, f.e. such code:
eval( { |p| eval( {|| qout( p + 1 ) } ) } )
is illegal in Clipper and Harbour. This limitation also can be
eliminated but but it will be necessary to make deeper modifications
in code for local detaching changing the method of generating
codeblocks local variables in nested blocks so unlike the above
also some modifications in HVM will be necessary.
Please test.

+ added hash items, f.e.:
local h1 := {=>}, h2 := { "a"=>1.234, "b"=>2.345 }
? h2[ "a" ], h2[ "b ]
+ added support for DYNAMIC function declaration - it allow to define
functions which are lately bound at runtime, f.e.:
/*** t01.prg ***/
dynamic func1
proc main()
local h:=__hrbload("t02.hrb")
? func1()
return
/*** t02.prg ***/
func func1
return "Hello!!!"
% use new FUNCALL structure to hold EXTERNAL and DYNAMIC functions,
it reduce memory usage, FUNCALL is much smaller then FUNCTION
% use symbol scope bits when possible instead of making some linear scan
+ added new enumarator message: __ENUMKEY - it allow to access
key value when hash item is base enumerator value, f.e.:
proc main()
local v, h:={"a"=>1.000,"b"=>2.000,"c"=>3.000}
heval( h, { |k,v,i| qout( k, v, i ) } ); ?
for each v in h
? v, "=>", v:__enumKey(), v:__enumValue(), v:__enumIndex(), ;
valtype(v:__enumBase())
v += 0.123
next
? ;heval( h, { |k,v,i| qout( k, v, i ) } )
return
+ added C level hb_hash*() functions
+ added support for full HASH item cloning and updated array cloning
to also clone nested hashes - please note that xHarbour does not do
that, in xHarbour ACLONE() clones _ONLY_ nested arrays and HCLONE()
_DOES_NOT_ clone _ANY_ nested items.
* harbour/include/hbextern.ch
+ added hash functions HB_H*()
* changed INET*() functions to HB_INET*()
+ added hash functions H*() and socket functions INET*() when
HB_COMPAT_XHB is set
* harbour/include/hbtypes.h
+ added missing HB_EXTERN_BEGIN / HB_EXTERN_END
* harbour/include/hbpp.h
* harbour/source/pp/ppcore.c
! added protection against automatic word concatenation in some cases
! fixed preprocessing expressions when match marker matches ';' token
* harbour/source/rtl/Makefile
+ harbour/source/rtl/itemseri.c
+ added functions for item serialization: HB_SERIALIZE() and
HB_DESERIALIZE() - these function are not binary compatible
with xHarbour functions with the same names but make very
similar job with the exception to serialization of codeblock
and object variables - Harbour does not allow to serialize
codeblocks and serialize objects as arrays.
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.
Please note that now hb_extIsArray() return TRUE only for pure arrays
not object values.

+ harbour/contrib/tip/url.prg
+ harbour/contrib/tip/utils.c
+ added TIP library - code borrowed from xHarbour
Please test - a lot of above code is not well tested, also some peaces
were written over year ago for different things (f.e. serialization for
NETRDD) and now I collected them and committed.
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)

* changed the internal compiler API to be MT safe.
All global and static non constant variables replaced by
HB_COMP structure which have all compiler context settings.
It's possible to allocate simultaneously many compiler contexts
and compile code. 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.

PP, new lexer and most of grammar parser should be MT safe. 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.

public PP API to not force including static rules by programs
which does not need them.
+ added basic API for using PP as lexer
* divided HB_PP_TOKEN_MACRO to HB_PP_TOKEN_MACROVAR and
HB_PP_TOKEN_MACROTEXT and mark
[<keyword>][&<keyword>[.[<nextidchars>]]]+
as HB_PP_TOKEN_MACROTEXT not pair HB_PP_TOKEN_KEYWORD and
HB_PP_TOKEN_MACRO
It allows easier integration PP as (macro)compiler lexer and
fixes preprocessing [<keyword>][&<keyword>[.[<nextidchars>]]]+
in some patterns.
* harbour/utils/hbtest/Makefile
+ added PP library to linked library list
* harbour/source/macro/macro.y
+ added seaport to use PP as lexer. It's disabled by default and
can be enabled using by defining HB_PP_MACROLEX. It eliminates
using FLEX or SIMPLEX lexer in macro compiler. Now it emulates
the behavior of FLEX lexer because I wanted to minimize the
modification but in fact because parsed token are freed when
macro compiler finish its job then we can resolve RT memory
leaks which apear during parsing wrong expressions. It will be
enough to drop allocating memory for new terminal symbols and
using them as is like in compiler. It will also quite nice
simplify include/hbexpr*.c code and will allow to move some
functions to COMMON library. I want to make also pure compiler
code MT safe so I will have to add passing pointer to a structure
with compiler context just like in macro compiler. It means that
if we define a structure which will be common to compiler and macro
compiler with local (not common) data stored in other structure for
which will will keep only a pointer then we will be able to move most
of include/hbexpr*.c code to common library. But I do not want to
make farther modification without consultation without Ryszard.
Also to make PP default lexer some farther modifications should
be done in core PP code and include/hbexpr*.c files to not reduce
the speed. Now using HB_PP_MACROLEX for sure will have to cause
speed reduction in macro compiler. But if we make necessary
modifications then we should keep at least the same speed or
probably reach noticeable better results.

__PP_FREE( <pPP> )
free PP context.
__PP_PATH( <pPP>, <cPath> [, <lClearPrev>] )

* harbour/source/pp/pplib.c
* restored support for old hb_inLine() syntax
+ added support for hb_inLine() to new PP. It can be enabled by
-kI compiler switch. It's disabled by default.
The new hb_inLine{} syntax is:
[ <exp> ] hb_inLine [ ( [<params,...>] ) ] { [ <c_code> ] } [ <exp> ]
<c_code> can contain new line characters.
Nested hb_inLine{} in <params,...> is not supported. If you think
it's important I can add it in few lines.
This version does not break any valid Clipper syntax, hb_inLine is
not reserved word and hb_inLine can be repeated many times in the
same line. F.e. this code can be properly preprocessed and compied if
you disable in compiler old hb_inLine() syntax and enable the new one
by -kcI Harbour compiler switch:
proc main()
local hb_inLine := " (var) "
? hb_inLine{ hb_retc("inLine"); } + hb_inLine(" parameter ") {
hb_retc( hb_parc( 1 ) );
} + "!" + hb_inLine + hb_inLine() { hb_retc( ":-)" ); } + ;
hb_inLine() + "{}"
return
function hb_inLine()
return " func() "
So from user point of view this version have real "inline" syntax.
To be clear: I'm not a fun of any C inline extensions. They works
only when we use .c code as compiler backend so the code which uses
them cannot be used in .hrb files and any other format we will add
in the future which do not support later C code compilation. F.e it
will not work in compiler integrated with HVM or with .NET
Anyhow if someone finds it useful then I think that it should be
properly implemented. This is the reason I added the new version.
The old one I left only for backward compatibility. It breaks any
code which uses hb_inLine keyword can be used only once in a line
and it does not have "inline" so IMHO it should not be enabled by
default.
I would like to hear your opinion about default compiler switches:
1. should we disable both: hb_inLine() and hb_inLine {}
2. should we disable hb_inLine() and enable hb_inLine {}
3. should we disable hb_inLine {} and enable hb_inLine()
4. should we enable both: hb_inLine() and hb_inLine {}

+ New PP code written from scratch. It works in similar way to
Clipper PP even the error codes are replicated. The code is MT
safe does not have any limitation on size of preprocessed code,
line, etc. It's also Clipper compatible lexer. It means that
we do not longer need FLEX or SIMPLEX which can be replaced
by new PP after some small modifications. Anyhow I haven't
decided to make it myself. I would like to agree with with the
rest of developers. I will be very happy if such modifications
will be done by someone else, Ryszard?
Meanwhile I current PP join on output the line tokens and give
the string line to FLEX/SIMPLEX. It does not have any sense and
all FLEX/SIMPLEX limitations are still existing. Ryszard, even
if we keep it then I hope you can remove at least FLEX line buffer
and use the one returned from PP.
Because string tokens in parsed line are converted to text which is
later once again decoded to tokens by FLEX I had to introduce new
string format which supports embedded string delimiters. I chose
modified version of xHarbour extension with escaped strings e"<sting>"
so now FLEX understand such strings and decode them like C escaped
strings. It means that you can use them also in the .prg code f.e.:
outstd( e"Hello\n\rWorld" )
The new PP is also noticeable faster. You should see the difference
compiling long files. The build in PP rules are generated automatically
by ppgen program created from source/pp/ppgen.c
I had to add to GNU source/pp/Makefile these two lines:
pptable.c : ppgen$(EXE_EXT)
./ppgen$(EXE_EXT) $(TOP)$(ROOT)include/hbstdgen.ch -opptable.c -q
Sth like that will have to be done also in non GNU make system.
Now Harbour can be compiled only using GNU make.
Marek can you update non GNU make files? I would like to leave this
modification to you or other developers who can test it.
It was quite big modification and I do not believe that I haven't
make any mistakes but I hope that in few weeks I'll fix any reported
bugs and it will resolve any PP problems.
TODO:
* error messages
create one common list of errors and warnings and keep it
in common library. PP and compiler can still generate different
errors with the same number. It can be confusing for the users
and hard to document and add i18n translations.
If possible we should also try to keep Clipper error numbers.
In new PP code I added Clipper error numbers but I cannot use
them until compiler code is not updated.
We should aslo remove the ctype passed to error functions and
hack with first character in warning messages and use only
error number. The codes from 1000 to 1999 should be warnings
where range 1000:1099 is activated by -w, 1100:1199 by -w1,
1200:1299 by -w2, etc. 2000:2999 are errors and 3000:3999
fatal errors. All compiler functions which generate an error
should expect that error function will not stop the compiler
but return and cleanly finished their job. It's necessary for
MT support in compiler and making compiler part of some other
programs which may still work and compile different source code.
* FLEX/SIMPLEX
remove them at all and add some final pass to PP to create
more precise tokens for grammar parser or at least add better
integration to remove some redundant code and existing limits.
* hb_inLine() support - it's broken in new PP but as I can see
it was never working correctly. I can add a hack to PP to support
hb_inLine() but I'm not sure it's worth to do. Maybe in few days.
+ harbour/include/std.ch
+ added new std.ch. It was created without using Clipper's std.ch.
It's quite possible that some rules are wrong and should be fixed
so please help. Anyhow I created a set of programs based on new PP
code generating all possible combinations of different commands I
collected from different source code, documentation and match patterns
of rules I was adding to new std.ch and then I was comparing .ppo
files generated by Clipper and Harbour so I do not expect any bigger
problems then some minor typos. I had to introduce some modifications
in spacing as workaround for FLEX/SIMPLEX which cannot properly decode
text preprocessed by Clipper after stringify.
* harbour/utils/hbpptest/pretest.prg
* updated for new PP
It reports 16 wrong translations but some of them are valid
and some others are caused by escaped string e"..." (one of hack
for FLEX/SIMPLEX support)
I also had to remove all spaces in comparison the results
because they were not Clipper ocmpatible at all. Ryszard please
look at it.

* fixed compilation of code that uses '@' pass by
reference. The following syntax is no longer supported:
var := IIF( .T., @var, var )
however you can still use the following:
funcall( IIF( bPassbyRef, @someVar, someVar ) )
+added support for the following statement:
WITH OBJECT <objexpression>
...
END
inside this statement you can use simplified form of sending
messages to the object specified by <objexpression>
:message( ) instead objexpression:message()
:property instead objexpression:property
The runtime error will be generated at the time of message
sending (or property access/assign) if <objexpression>
is not a value of type object.
You can use the reserved property:
:__withobject
to access/assign the controlling object.
*fixed support for command line response file (@file.clp)
to be compatible with Clipper (Clipper genertes a single
obj file)

<var1>:=<val>[; <varN>:=<val>]
* fixed compilation of optional clauses (when used in different
order then declared) -this fixes the following long
waiting bug:
#command MYCOMMAND [<mylist,...>] [MYCLAUSE <myval>] => ;
MyFunction( {<mylist>} [, <myval>] )

and fill allocated and freed memory with HB_MEMFILER (0xff by default)
It's for debugging only.
* harbour/source/vm/hvm.c
! fixed hb_vmTopNumber() declaration for BCC
* use hb_gcCollectAll() at HVM exit instead of hb_gcReleaseAll() to
report allocated and not freed items - It could caused that some

BTW - is this really necessary? I copy it form hb_itemUnRef()
but in fact it cannot detect all possible item reference cycles
if they appear - can they appear?
