* 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.

with HB_IT_TIMESTAMP - it simplifies HVM code and eliminates additional
RT conditions.
+ added HB_IS_TIMESTAMP() and ISTIMESTAMP() macros

<, <=, >, >=, =, ==
When two timestamp values are compared then VM compares date and
time parts in both 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: "-", "/", "."
T - is literal "T" - it's for XML timestamp format
if PM or AM is used HH is in range < 1 : 12 > otherwise
in range < 0 : 23 >
HB_HOUR( <tTimeStamp> ) -> <nHour>
HB_MINUTE( <tTimeStamp> ) -> <nMinute>

which replicate HVM behavior.
SEEK and SEEKLAST with date value when active index is on
timestamp positions to 1-st or last record where date part
of indexed timesamp value is equal.
Settings scopes to date values when active index is on timestamp
value reduce the visible record range to these ones which have
date part of timestamp value in the range of dates values used
for scopes. It possible to mix date and timestamp values in scope
and set one scope to date value and the second to timesamp.

+ updated HB_UnzipFileInfo( hUnzip, @cZipName, @tDateTime, @cTime, ... )
to return timestamp value in 3-rd parameter instead of date value.
TODO: Please think about removing 4-th parameter from:
HB_ZipFileCreate( hZip, cZipName, tDateTime, cTime, ... )
HB_UnzipFileInfo( hUnzip, @cZipName, @tDateTime, @cTime, ... )
Now it's redundant.

WOM(), WOY(), EOY() and BOY() functions
The following contrib files should be updated but I'm leaving it to
other developers who want to keep this code alive:
contrib/hbtip/utils.c
contrib/hbvpdf/hbvpdf.prg
contrib/hbvpdf/hbvpdft.prg
contrib/hbwin/win_dll.c
some minor cleanups if necessary and authors will find
timestamp values usable
contrib/hbole/ole2.c
contrib/hbwin/win_ole.c
add support for timestamp values in OLE
contrib/rddado/adordd.prg
contrib/rddads/ads1.c
contrib/rddads/adsx.c
contrib/rddsql/...
add support for timestamp values in RDDs
Warning: this implementation is not xHarbour compatible. There are many
important differences. Mostly on C level and used API. Please be careful
in porting xHarbour source code to Harbour.

* 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 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

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()

* 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.

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.

+ 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.

! fixed wrong negate optimizations for platforms where HB_LONG_MAX
is smaller then -HB_LONG_MIN, f.e. all x86 based CPUs.
! fixed setting the size in optimized negative numbers
! fixed some math optimizations to not use casting to double value
when it's not necessary - when double precision is smaller then HB_LONG
(f.e. on x86 it's 53 bits and HB_LONG has 64bit) such casting can damage
up to 11 less significant bits in big 64 bit numbers.
* harbour/source/rtl/hbinet.c
* replaced MAKEWORD() macro with HB_MKWORD() to pacify BCC58 warnings
* harbour/include/hbdefs.h
+ added #include <limits.h>
It should hide some warnings related to redefined integer size constants
Viktor if it will not help for BCC58 warnings then you will have to add
#include <stdint.h>
few lines below but please remember that older BCC version does not
have it so check for the exact compiler version.
! changed macros which setting default numeric item size for more strict
Clipper compatible mode. I'm not a fun of some Clipper behavior in
calculating number size and I left some notes about it in hbdefs.h
Anyhow this and some other modifications below should cover the
differences you've found recently. Some things are not addressed by
me intentionally, f.e. _itemPutNL() in Clipper always set size to 10
without checking the maximum size so it's too small for values less
then -999999999. Harbour compiler makes more compile time optimizations
then Clipper. The formatting rules used by compiler are a little bit
different then by VM so this can be source of some other differences
to Clipper. I can easy create some examples. Harbour supports 64bit
signed integers and Clipper doesn't. This is yet another situation
when we may have different results then Clipper. Most of them can
be hidden if we add new PCODE(s) for integer number with explicit
size but I do not think it's such important to increase PCODE list.
In few cases it will be necessary to disable some optimizations at
all and I do not like it. In the future when I will be adding some
new optimizations I also add compiler switch to disable/enable
optimizations which can have such side effects for people who need
strict formatting.

or FOR expression) then they were not properly evaluated.
* harbour/source/vm/macro.c
* minor improvement
* harbour/utils/hbtest/rt_misc.prg
! fixed one of expected result, it was neither Harbour nor Clipper
result (I've just made some test with Clipper), I do not know why
it existed

* harbour/contrib/rdd_ads/adsfunc.c
* harbour/source/rdd/workarea.c
* formatting
* harbour/include/hbapi.h
* harbour/source/vm/extend.c
+ added missing hb_storptrGC()
* harbour/include/hbapicdp.h
* harbour/source/rtl/cdpapi.c
+ added parameter to unicode translation function to protect control
code translation
* formatting
* harbour/source/rtl/gtsln/kbsln.c
* harbour/source/rtl/gtxwc/gtxwc.c
* use new unicode translation function format. It also fixes problem
with space translation in GTLSN used in UTF8 mode
* harbour/include/hbapiitm.h
* harbour/source/vm/itemapi.c
+ added hb_itemCopyToRef(), hb_itemMoveToRef(), hb_itemMoveRef(),
hb_itemUnRefWrite()
* harbour/include/hbexprb.c
! use HB_P_DUPLUNREF instead of HB_P_DUPLICATE when assign is used in
push context - Clipper compatible behavior, see:
x:=10
f(y:=iif(.t.,@x,))
? x, y
func f(x)
x+=100
return nil
* harbour/include/hbver.h
* harbour/source/common/hbver.c
* changed status to "devel"
* harbour/source/common/expropt2.c
* disabled setting NIL when iif(.t.,,sth()) is optimized to avoid
warning when iif() is used as statement - to fix number of parameters
passed to function in code like f(iif(.t.,,sth())) we will need a
little bit deeper modification
* harbour/source/compiler/complex.c
* added hack for potential problems caused by WITH OBJECT syntax, f.e.
in code like:
proc p(obj,x)
case:=myCaseClass():new()
retu:=myCaseClass():new()
WITH OBJECT obj
do case
case x==nil
case:value()
case:action()
retu:sth()
end
END
case:action()
retu:sth()
return
case:action(), case:value(), retu:sth() can means two different things
and compiler cannot guess which one should use. It cannot be fixed
because it's caused by bad WITH OBJECT syntax. In xHarbour constractions
like case:value() or retu:sth() are always used as in WITH OBJECT
context what is not Clipper compatible. I do not want to introduce
such limitations. We have two choices: change WITH OBJECT syntax or
add some hack to "hide" the problem a little bit. Now I intorduce
ugly hack which check number of spaces between ':' so
case :action()
is compiled as case condition using WITH OBJECT message and
case:action() as sending message to object in case variable
* harbour/source/compiler/harbour.y
* harbour/source/compiler/harbour.yyc
+ added support for passing base value to FOR EACH by reference.
* harbour/source/vm/arrays.c
* use hb_itemMoveRef() in AINS()/ADEL() to avoid creation of cyclic
reference chains
* harbour/source/vm/debug.c
* harbour/source/vm/memvars.c
* use hb_itemCopyToRef() to avoid creation of cyclic reference chains
* harbour/source/vm/classes.c
* harbour/source/vm/hvm.c
* use hb_itemMoveToRef() to avoid creation of cyclic reference chains
+ added support for for writable string enumerators, f.e.:
proc main()
local s, c
s:="abcdefghijklmnopqrst"
for each c in @s
if c$"aeio"
c:="*"
endif
next
? s // "*bcd*fgh*jklmn*pqrst"
return

* keep prefix definition for bison public symbols in *.y files instead

*.yy[hc] file generation
! fixed iif() reduction when used as single function parameter
+ add -kM compiler switch - turn off macrotext substitution
* updated <string> + <string> optimization and other macrotext usage
to keep more Clipper compatible behavior
! fixed typo in expression type checking in IIF() reduction - it was
working because wrongly used macros has the same values as the valid
ones
- removed compiler switches and macros for old HB_INLINE() syntax - it
was not supported after last months modifications. Only:
HB_INLINE([params,...]) { C code }
is supported.
! fixed passing parameters by reference in IIF() statement and macro
compiler. The following valid Clipper code:
&("myfunc(<exp>, @var1, @var2)")
was not supported
! do not allow to use references or empty expressions in expression list
AFAIK it's Clipper compatible. If I'm wrong then please fix me but
Clipper allows to use references only as function arguments, 2-nd and
3-rd IIF() argument and as directly created array items ( {...@var...} )
DO ... WITH ... is a special case of function call.
! Changed grammar rules to accept only Clipper compatible parameters.
! fixed typo in macro name in hb_memvarNewParameter() function.
* use HB_FUNC_EXEC(...) instead of HB_FUNCNAME(...)()

* harbour/include/hbcompdf.h
+ added comment
* harbour/include/hbexpra.c
* change expression type for <exp> = <exp> from HB_EO_EQUAL
to HB_EO_ASSIGN in hb_compExprGenStatement() function so
later we can safely make all optimization in hb_compExprUseEqual()
during reduce process - optimization only when PCODE is generated
is too late and causes that expressions like:
iif( 1 = 1, <exp>, <exp> )
are not reduces (Clipper reduce them)
* do not execute hb_compFunCallCheck() in hb_compExprNewFunCall()
to avoid repeating the same error message in hb_compExprUseFunCall()
* harbour/include/hbexprb.c
* enabled reduction for hb_compExprUseEqual() and generate errors
when it's used as statement
* harbour/source/common/expropt2.c
* added some missing reductions for expressions like: NIL == NIL
* harbour/source/common/reserved.c
% very basic optimization: use binary search instead of linear
scanning for reserved words and shortcuts - it gives noticeable
speed improvement in macro compiler
* harbour/source/compiler/complex.c
* changed the order of special keywords to keep alphabetic sorting
* harbour/source/compiler/harbour.c
% some minor optimizations in aliased expressions
! added protection in hb_compIsJump() to avoid possible problems
when this function is executed after replacing some code with
jumps by series of NOOPs in optimizations process
* harbour/source/compiler/hbfix.c
* better optimization of PCODE generated for logical expressions
* harbour/source/compiler/hbfunchk.c
% use binary search instead of linear scan
* harbour/source/rtl/minmax.c
! fixed GPF when MIN() or MAX() function is called with less then
two parameters
* harbour/source/vm/itemapi.c

* harbour/include/hbexprb.c
* do not generate HB_P_FUNCPTR - it's not longer necessary
+ added optimization for <exp> + 1, <exp> - 1 - disabled by default
because it changes error messages in hbtest, code like NIL + 1
generates 'argument error ++' instead of 'argument error +'. I'd like
you will decide what you prefer - faster code or strict Clipper error
messaged.
* harbour/source/common/expropt2.c
+ added optimizations for <num> + <date>
+ added ooptimizations for <exp> + 0, 0 + <exp>, <exp> - 0
This is also sth what may interact with operators overloading in object
system. When we will have strong typing then we should think about an
option which will optionally disable some optimizations - someone may
want to define arithmetic where <obj> + 0 gives differ then <obj>
results.
* harbour/include/hbcomp.h
* harbour/source/compiler/harbour.c
* harbour/source/compiler/harbour.y
* harbour/source/compiler/harbour.yyc
* harbour/source/compiler/harbour.yyh
+ added hb_compStatmentStart()
! restrict MEMVAR and FIELD usage - now they have to be located before
executable statements like in Clipper.
! generate error when PARAMETERS is used as file wide declaration.
! generate errors when different executable statements are used before
first procedure - now such code was simply ignored without any errors.
! generate valid error messages when some declarations are used in
wrong places
! fixed setting begin of executable statement flag in different .prg
constructions.

+ added support for 16MB codeblocks and strings
! removed macrocompiler limitation for jumps range
! fixed GPF when more then 255 local variables is used and added
support for 2^15 locals
! removed all strtok() functions
% added optimization for all +=, -=, *=, %=, ^=, **= operations
when left side of expression is variable or array item
% added optimization for all +=, -=, *=, %=, ^=, **= operations
when left side of expression is object method and updated ++, --
for new code. It's still disabled until we will not add support
for late evaluated reference items to HVM
! fixed a[++i]++ and similar operations (a[++i]*=2, ...). Now ++i is
executed only once. It's not Clipper compatible but it was in
TODO note in source code. It can be disabled by -kc option
* finished support to xHarbour like #pragma TEXTHIDDEN(1)
! fixed local add int optimization when PARAMETERS used after
optimization changed local variable number over 255
! fixed GPF trap when in HB_P_<op>EQ PCODEs when executed for
direct values
* others
! fixed problems reported by Chen
* optimized strtran(), left(), right() to not create new string copy
when the same value is returned

It fixed some possible buffer overflow but it's also possible that
it will exploit some some hidden so far problems but I strongly
prefer to know about them ASAP to fix them before final 1.0 release.
! fixed bug I introduce in codeblock falgs which disabled early macro
evaluation in codeblocks.
! added missing protection against execution by bison destructor for
used CBSTART token on syntax error.
% use PP stringify logik added for FLEX support to remove all redundant
spaces in stringified for early macro evaluation codeblocks and add
spaces between operators if after preprocessing they were removed.
Now we are supporting also some code which cannot be compiled by
Clipper.
% cleaned and improved the speed of printer redirecting in console code.
Chen please check if CG still reports problems and if not ubdate
TODO/TOFIX or inform me about them.
* some cleanups in building process for different *nixes: MacOSX, SunOS,
*BSD, etc.
* removed not longer necessary (I hope) compiler flag to force default
'char' type as signed. 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.

! do not use bison destructors for expressions. Internal bison logic
cannot properly detect if expression was used or not in some of our
grammar rules and it's possible that some expressions will not be freed
and some other freed twice.
! added protection against multiple destructors execution for CBSTART
and LITERAL tokens
* added small garbage collector for deallocating expressions which were
not freed (such situation can happen in syntax errors)
% some optimizations in used structures to reduce their sizes
+ added protection against execution PCODE optimizations for functions
which were not cleanly compiled.

* hide HB_MACRO internal definitions in hbapi.h when HB_MACRO_SUPPORT

These modifications should help in future compiler and macro compiler
integration into single binary.
+ added clipper compatible error message in unclosed structures
In general we should cleanup rules to make error reporting more
user friendly and Clipper compatible
% eliminated unnecessary allocations
+ added int mode member to common part of HB_COMP and HB_MACRO
structure. It's initialized to HB_MODE_MACRO or HB_MODE_COMPILER
+ add TOFIX note about memory leaks in cParamTypes and pParamClasses
members of COMDECLARED structure. It's a part of unfinished strong
typing code. I do not know what Ryszard plan to do with it so I'm
leaving it as is. The part of strong typing which were operating
on emulated HVM stack has been removed.
* removed static variables from genjava.c. Also gencli.c and genobj32.c
should be fixed but this will not make this code working so I haven't
touched it.
* changed 3-rd parameter of hb_compIdentifierNew() from BOOL to int.
Now it can have the following values: HB_IDENT_STATIC, HB_IDENT_FREE,
HB_IDENT_COPY. This modification will allow in the future using common
for static and dynamic symbol hash table without additional source code
changes. I also plan to use identifier hash table in PP the reduce
number of memory allocations and speed-up preprocessing by using
second level hashing for hash keys.
* harbour/source/common/expropt1.c
* harbour/source/common/expropt2.c
* changed HB_MACRO_SUPPORT to HB_COMMON_SUPPORT to automatically detect
possible conflicts between compiler and macro compiler
! removed first detected conflict which existed for long time
+ added hb_compExprMacroAsAlias() function to convert HB_ET_VARIABLE
expression to HB_ET_ALIAS.
* harbour/source/macro/macro.y
! fixed using prefix¯o-> and ¯o.sufix-> when macro cannot be
substituted by compiler, f.e.:
M->v := NIL
x := "&v.1->fld"
M->v := "v"
M->v1:= "data"
? &x
! fixed memory leak in macro substituted expression compilation
* harbour/source/vm/macro.c
! fixed initialization of some HB_MACRO members
! fixed value returned for type("&V->F") when alias does not exist
- removed not longer used hb_comp_bShortCuts global variable

* 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.

* do not allocate separate memory in macro compiler for terminal
symbols which needs string representation - it fixes some set
of memory leaks and increase a little bit macro compilation

private cMacro := "cEarly", cEarly := {"Early"}
@ 12,10 GET &cMacro[1]
! fixed GPF in:
p:=@left()
and similar expressions
