memory buffers
* harbour/source/compiler/hbcmplib.c
+ added HB_COMPILEBUF() functions which returns compiled .hrb file
as string item
* harbour/source/vm/runner.c
+ added support for executing compiled .hrb files stored in string
items in __HRBRUN() function - it works just like in __HRBLOAD()

as harbour compiler and makes the same job :-)
* harbour/utils/hbrun/Makefile
* harbour/utils/hbrun/hbrun.prg
+ added support for compilation and direct execution of .prg files
Now hbrun can accept as first parameter .hrb or .prg file and if
it's .prg file it's compiled and then executed just like .hrb one.
In *nixes if you copy compiled hbrun to /usr/bin directory then
you can add to your .prg files as first line:
#!/usr/bin/hbrun
and then after setting executable attribute you can directly
execute them, f.e.:
./test.prg
If you are using Linux then you can also chose default gt driver
by dding to above line: //gt<name>
F.e.
#!/usr/bin/hbrun //gtstd
* harbour/contrib/tip/Makefile
- harbour/contrib/tip/atokens.c
* removed HB_ATOKENS()
- harbour/source/rtl/teditorl.c
- removed __STRTOKEN(), __STRTKPTR()
* harbour/common.mak
* harbour/source/rtl/Makefile
* harbour/include/hbextern.ch
+ harbour/source/rtl/hbtoken.c
+ added set of functions to manipulate string tokens:
HB_TOKENCOUNT( <cString>, [ <cDelim> ], [ <lSkipStrings> ],
[ <lDoubleQuoteOnly> ] ) -> <nTokens>
HB_TOKENGET( <cString>, <nToken>, [ <cDelim> ], [ <lSkipStrings> ],
[ <lDoubleQuoteOnly> ] ) -> <cToken>
HB_TOKENPTR( <cString>, @<nSkip>, [ <cDelim> ], [ <lSkipStrings> ],
[ <lDoubleQuoteOnly> ] ) -> <cToken>
HB_ATOKENS( <cString>, [ <cDelim> ], [ <lSkipStrings> ],
[ <lDoubleQuoteOnly> ] ) -> <aTokens>
All these functions use the same method of tokenization. They can
accept as delimiters string longer then one character. By default
they are using " " as delimiter. " " delimiter has special mening
Unlike other delimiters repeted ' ' characters does not create empty
tokens, f.e.: HB_ATOKENS( " 1 2 3 " ) returns array { "1", "2" }
Any other delimiters are restrictly counted, f.e. HB_ATOKENS( ",,1,,2,")
return array: { "", "", "1", "", "2", "" }.
+ added emulation for old __STRTOKEN(), __STRTKPTR() and xHarbour's
__STRTOKENCOUNT() by HB_TOKEN*() functions. They do not return
exactly the same result as __STRT*() functions which in some cases
ignored some delimiters and return wrong results.
* harbour/source/rdd/Makefile
+ harbour/source/rdd/dbsql.c
+ added __DBSQL() function
* harbour/include/hbsetup.h
* harbour/source/vm/fm.c
+ added support for native Windows memory allocation functions
It can be enabled by HB_FM_WIN32_ALLOC macro and disable C-RTL
memory manager.

+ 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.

+ 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)
* harbour/include/hbapi.h
* harbour/include/hbapiitm.h
* harbour/source/vm/garbage.c
* harbour/source/vm/extend.c
* harbour/source/vm/itemapi.c
+ added hb_gcFunc(), hb_parptrGC(), hb_itemGetPtrGC()
hb_parptrGC() and hb_itemGetPtrGC() uses GC cleanup function address

+ harbour/include/hbregex.h
+ harbour/source/rtl/hbregex.c
* harbour/source/rtl/Makefile
* harbour/common.mak
+ added support for regular expressions. Now it's enabled by default
only in *nixes (POSIX regex) and BCC 5.5 (PCRE regex). Setting
HB_PCRE_REGEX macro enables Perl-Compatible Regular Expressions
and HB_POSIX_REGEX - POSIX regular expressions. In xHarbour regex
support is enabled for all builds because PCRE source code is stored
in CVS. If you will want we can make the same.
+ the following C functions are available:
hb_regexCompile(), hb_regexGet(), hb_regexFree(), hb_regexMatch()
+ the following PGR functions are available:
HB_REGEXCOMP(), HB_ISREGEX(), HB_ATX(), HB_REGEX(), HB_REGEXMATCH(),
HB_REGEXSPLIT(), HB_REGEXATX(), HB_REGEXALL()
They are working in similar way to the ones in xHarbour with the
exception to some bug fixes and form of compiled regular expression.
In Harbour it's pointer item for which HB_ISREGEX() returns TRUE when
in xHarbour it's binary string.

! added protection against cyclic references in arrays
* eliminated action parameter from hb_vmRequestReenter() /
hb_vmRequestRestore()
* moved s_lRecoverBase and s_uiActionRequest to HB_STACK structure
for future MT HVM version
+ added internal item structure hb_struRecover - it's not real item
but this structure is used to keep information about BEGIN SEQUENCE
data - it reduce HB_STACK usage
+ added support for ALWAYS clause in BEGIN SEQUENCE
The syntax is:
BEGIN SEQUENCE
<code>
[ RECOVER [ USING oErr ] ]
<recoverCode>
[ ALWAYS ]
<alwaysCode>
END [ SEQUENCE ]
It's guaranteed that <alwaysCode> is _ALWAYS_ executed even if
inside <code> or <recoverCode> some new exceptions like RETURN,
BREAK or QUIT will appear.
Please note that when the following code is executed:
BEGIN SEQUENCE
<code>
ALWAYS
<alwaysCode>
END
(without RECOVER clause) then BREAK exception inside <code> is not
recovered, <alwaysCode> is executed and then BREAK exception is
passed to outer BEGIN SEQUENCE. This is the same semantic as
used in TRY / [ CATCH ] / FINALLY / END
Those of you who prefer to use TRY / CATCH / FINALLY / END instead
of BEGIN SEQUENCE / RECOVER / ALWAYS / END can simply add to your
source code:
#command TRY => BEGIN SEQUENCE
#command CATCH [ oErr ] => RECOVER [ USING <oErr> ]
and:
errorBlock( {|oErr| break( oErr ) } )
Though instead of 'break( oErr )' I suggest to use some small function
which will support some basic recovery/substitute operations like in
default errorsys() and LockErrHandler() to not break existing code
which may depends on the default behavior.
If you want I can add direct support for TRY / CATCH / FINALLY / END
but I'm not sure it's really necessary.
Please note also that in Harbour ALWAYS code is execute even for QUIT
excpetion.
When <alwaysCode> is executed current exception is stored and restored
when is finished. If new exception appears inside <alwaysCode> then
restored exception depends on the priority in the following order:
QUIT // highest priority
BREAK
RETURN
If both exceptions have the same priority and contain additional value
(error object in BREAK or return value in RETURN) then the recently set
one is restored. It's similar behavior to destructor code.
* harbour/source/common/hbstr.c

to use it also in compiler and preprocessor
* harbour/source/compiler/ppcomp.c
* harbour/source/pp/ppcore.c
* harbour/source/pp/pplib.c
* tuned error messages to be more Clipper compatible
% use static strings from hb_szAscii
* harbour/source/rtl/alert.prg
* use hb_gtInfo( GTI_FULLSCREEN ) to detect type of GT driver
! some minor fixes
TOFIX: we have to also use GTI_ISCTWIN or add window allocation
to standard GT drivers to be Clipper compatible when CTWIN
is used - In Clipper Tools ALERT() works in differ way then
the standard one. It creates separate window box to display
data, supports SETKEY(), etc. I'll think about adding some
extended support for ALERT() and similar operations (f.e.
separate debugger windows) to GT API so it will be also
possible to overload standard alert() command by GUI message
box in GTGUI and similar GT drivers.

! fixed typo in hb_xvmGreaterEqualThenIntIs() - <= was used instead
of >=
! fixed :¯o() messages used in WITH OBJECT structure and -gc3
output
+ added some missing optimizations in -gc3 output
* harbour/contrib/libct/ctc.c
* harbour/contrib/libct/files.c
* harbour/contrib/libnf/ftattr.c
* harbour/contrib/libnf/n2color.c
* cleaned some BCC warnings

* harbour/source/common/hbverdsp.c
* harbour/source/compiler/hbcomp.c
* harbour/source/vm/arrays.c
* harbour/source/vm/arrayshb.c
* harbour/source/vm/cmdarg.c
* harbour/source/vm/hvm.c
! fixed Harbour support for accessing string characters with array
index operators []
+ added support for #define HB_COMPAT_XHB - it's disabled by default.
When set it enables some of xHarbour features like negative array
indexes calculated from tail, accessing string characters with []
operators (warning it's not compatible with default Harbour version
enabled by -ks during compilation and //flags:s at runtime - in
xHarbour compatibility mode "ABC"[2] returns "B" when in Harbour 66)
and some other minor features.
* harbour/source/compiler/cmdcheck.c
* added support for optional setting C output type in -go switch
Now it accepts optional digit [0123] after -go in the same way
as -gc, f.e.: -go3
* harbour/source/compiler/harbour.c
* call hb_compExprLstDealloc() only when errors appeared during
compilation - it disable automatic freeing all allocated expressions
in clean compilation. I make it intentionally for easier detecting
problems one some expressions are not freed. So far the final cleanup
code always deallocated expressions what can hide some real bugs.
* harbour/source/vm/hvm.c
! fixed very serious bug in HVM closing. The s_uiActionRequest flag
was not cleared before hb_rddShutDown() so when RDD buffers were
hot and flushing required some PCODE evaluation (f.e. index KEY
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
* harbour/source/compiler/hbusage.c
* update the year in hb_compPrintLogo() from 2006 to 2007
* harbour/source/vm/garbage.c
! fixed potentially very serious bug - when I added array items
references I forgot to update GC. Fortunately it was caught
by code to detect bugs in object destructors so only RT error
was reported instead of internal HVM memory corruption
* harbour/tests/hbinline.prg
* updated comments
* harbour/source/vm/hvm.c
* small modification to protect against creating long references chains
which can hardly reduce the performance in some cases
* harbour/include/hbcomp.h

* harbour/source/vm/memvclip.c
* keep prefix definition for bison public symbols in *.y files instead
of passing them as bison arguments to avoid possible mistakes during
*.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
* minor optimization and formatting
* harbour/include/hbcomp.h
* harbour/include/hbcompdf.h

* harbour/source/macro/macro.yyc
* harbour/source/macro/macro.yyh
* harbour/source/macro/macrolex.c
* harbour/source/vm/macro.c
* final grammar cleanup: removed unused and/or unnecessary grammar
expressions in *.y files, fixed some differences between compiler
and macrocompiler, fixed some other bugs, typos, clipper
incompatibilities, etc.
It's end of year, it's late and sorry but I'd like to begin making
something absolutely differ then creating detail description ;-)
If you will have any questions then I'll answer in new year.
* harbour/source/rdd/dbffpt/Makefile

* accept ... in codeblocks only when codeblocks parameters are defined
as variables, f.e: {|a,b,...|qout(a+b,...)}
! fixed error in a[&s]:=100
+ added support for a[...] - now ... can be used in the same context as

qout( a, b, "X", ... )
* forbid creating function pointer when function is used with parameters,
f.e.: x:=@f1(1,2,3)
* harbour/source/compiler/complex.c
* cleaned all restrictions on reserved words I've found - if I missed
sth then please inform me. The previous behavior and some error
messages are used with -kc compiler switch
* harbour/source/rtl/symbol.prg
* harbour/source/rtl/tobject.prg
! eliminated limitations in number of constructor parameters
(new syntax with passing optional parameters used)
* harbour/contrib/rdd_ads/adsfunc.c
* do not use hb_param( pItem, HB_IT_BYREF ) but ISBYREF() macro
* harbour/include/hbdefs.h
* formatting
* harbour/include/hbexprb.c
! fixed code generated for logical expressions when shortcutting
is enabled to be Clipper compatible
* harbour/source/compiler/cmdcheck.c
! added missing break in -z compiler switch decoding
* harbour/source/compiler/hbfix.c
% added optimizations for code generated for logical expressions,
it strips a chain of HB_P_DUPLICATE -> HB_P_JUMP[TRUFALES] ->
HB_P_DUPLICATE -> HB_P_JUMP[TRUFALES] -> ...
In fact it should not be done here but because we do not have
any metacode level where such optimizations should be done and
PCODE is generated online then it will have to be here. Maybe
in the future we will add metacode.
* harbour/source/rdd/dbcmd.c
* make "M" alias Clipper compatible. After some thoughts I decided
that in some cases it can be usable so now "M" will set WA number
to 65535 like in Clipper.
* harbour/source/rdd/dbf1.c
* allow to open VFP DBFs with _NullFlags system command
* harbour/source/rdd/delim1.c
* harbour/source/rdd/sdf1.c
! updated field size calculation for some some extended types.
* harbour/source/rdd/workarea.c
* generate RT error when CREATEFIELD() method does not accept some
parameters to avoid silent DBCREATE() failing.
* harbour/source/vm/macro.c
* removed hb_compMemvarCheck() - this function was not dooing
anything - only slows the TYPE() by calling hb_dynsymFind()
one or two times.
+ added TODO note: memvars create by TYPE() have PUBLIC scope
in Clipper. Clipper also always tries to evaluate valid expressions
inside TYPE even if the contain UDF. UDF only stops evaluation
so:
TYPE( "(val:=1) + f() + (val2:=2)" )
creates in clipper public variable VAL but not VAL2.
* harbour/config/w32/bcc32.cf
* cleanup
+ harbour/config/w32/xcc.cf
+ added XCC support
* harbour/contrib/btree/hb_btree.c
* use hb_vmAtInit()/hb_vmAtExit() instead of INIT/EXIT functions defined
from C code
* harbour/contrib/libct/tab.c
* casting
* harbour/contrib/odbc/odbc.c
! removed #include <malloc.h> - it should not be used with new C
compilers
I think that we should replace this library with hbodbc from xHarbour.
* harbour/contrib/ole/ole2.c
* updated for XCC
* harbour/include/hbdefs.h
* include stdint.h if available
* harbour/source/compiler/complex.c

* harbour/include/hbcompdf.h
* harbour/include/hbexpra.c
* harbour/include/hbexprb.c
* harbour/include/hbexprc.c
* harbour/include/hbexprop.h
! fixed GPF during compilation of @:var, @:&var, @o:&var
+ added support for @o:&var and @:var, @:&var inside WITH OBJECT
statement
* changed PCODE generated of ++,--,+=,-=,...
Now left side expression is evaluated _ONLY_ once and when object
messages are used it's guarantied that exactly the same object
variable will be used. It also fixes some problems which exists
in Clipper. This optimization is enabled by -kh flag (by default)
and can be disabled with -kc.
% optimize ald macros in ++,--,+=,-=,... operations
* add automatically "_" prefix when macro message is used in assignment
context, f.e.:
s:="osCode"
o:=errorNew()
? o:&s
o:&s := 100
? ++o:&s
? o:&s *= 5
* harbour/include/hblang.ch
- removed #xtranslate - this file is included by C code and some C
compiler do not like unknown directives
* harbour/utils/hbtest/rt_math.prg

source code:
! fixed GPF traps when too long string or codeblock is generatd
+ 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
* harbour/include/hbstack.h
! fixed typo in function name, should be: hb_stackLocalVariable()
not hb_stacklocalVariable()
+ added hb_stackId()
* hide hb_stack declaration when HB_STACK_MACROS is not set
* harbour/source/vm/dynlibhb.c
* use hb_stackId()
* harbour/source/vm/estack.c
+ added hb_stackId()
! fixed some condition used to check stack access - they were

and hb_strn*(), sprintf() by snprintf(), etc.
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.

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

* harbour/source/compiler/harbour.y
* harbour/source/macro/macro.y
+ added support for strings with with ASCII NUL character
Strings with ASCII NUL character are not stored with hash table
but dynamically allocated/deallocated
! fixed compilation of strings with ASCII NUL character which
can appear in escaped strings e"..." or after compiler chr(0)
optimization
% removed some not longer necessary memory allocations
* harbour/source/vm/macro.c
! fixed GPF caused by HB_MACRO structure double freeing
- removed some code which was added as workaround for the old
behavior of HVM QUIT and false FM stat memory leak reports.
It's not longer necessary in current HVM.

* 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.

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.
* harbour/makefile.bc
* Adapted to the new Preprocessor utility ppgen.exe
* Cleaned hbpp.exe dependecies due to recent changes
* harbour/makefile.vc
* harbour/common.mak
* Cleaned hbpp.exe dependecies due to recent changes
* harbour/include/hbapi.h
* Added HB_EXPORT to hb_gcAlloc()
* harbour/include/hbstack.h
* Added HB_EXPORT to hb_stackSelfItem()
* harbour/source/vm/fm.c
* Added dipslaying contents of unreleased blocks at
program exit, together with logging unreleased memory
blocks report to fm.log file. Borrowed from xharbour.
* harbour/include/hbclass.ch
+ added validation for class data names. As additional preprocessor
rule to not use <!marker!>
* harbour/include/hboo.ch
* harbour/source/rtl/tclass.prg
* harbour/source/vm/classes.c
+ added delegate messages
* harbour/include/hbstack.h
* harbour/source/vm/arrays.c
* harbour/source/vm/estack.c
* harbour/source/vm/hvm.c
* harbour/source/vm/proc.c
+ added startup symbol to hb_stack. It gives very good stop
condition for all procedures which trace stack calls and
resolves the problem with hb_stack.pBase which was never
pointing to valid function/procedure symbol when no symbol
was put on HVM stack. Now after hb_stackInit() the first
item is allocated for "hb_stackInit()" symbol so hb_stack.pBase
is always a pointer to valid function/procedure symbol.
* changed the guard condition for buggy code in hb_stackPop()
and similar code from:
hb_stack.pPos < hb_stack.pItems
to:
hb_stack.pPos <= hb_stack.pBase
The old condition was generating usable error message only in the
startup function. In deeply called functions it was only waste of
CPU time on one of the most often call functions. Before it was
activated internal stack structures were corrupted.
If we were leaving for many years without really working stack
underflow protection then maybe we should think about disabling
it at when HB_STACK_MACROS are used and keep it only in real
stack functions for HVM developers. Single protection in
hb_stackOldFrame() I've just added is enough for basic C code
validation.
I created the second version of stack macros without it in
hbstack.h but I would like to hear other developers opinion.
* harbour/include/hbexprc.c
* translate HB_P_INC / HB_P_DEC in (pre|post)(inc|dec)rementation
to HB_P_[PLUS|MINUS]EQ
* harbour/source/vm/hvm.c
- removed not necessary now hb_itemUnRef() in hb_vmInc()/hb_vmDec()
* harbour/include/hbclass.ch
* most of the rules rewritten
! fixed some wrong rules and general cleanup
+ added additional code validation
! fixed compilation of more then one class in single file.
Now it's even possible to declare all classes at beginning of
single file and then implementing their methods in any order
! fixed using static classes and classes
! fixed compilation without <ClassName>_ prefix in method names
+ added support for HB_CLS_NO_DECORATION macro which disable
adding <ClassName>_ prefix to method names - this macro is
set by default when HB_SHORTNAMES is set.
+ added support for declared parameters validation - it can be
disabled with HB_CLS_NO_PARAMS_ERR and I had to disable it
by default due to problems with our preprocessor.
Ryszard seems that our PP has serious problems with decoding
directives when there is no space between symbol and some other
non symbol character. I had to add some workarounds and even
introduce buggy rules to make it working. Please look at it.
You can remove #define HB_CLS_NO_PARAMS_ERR from hbclass.ch
and try to rebuild Harbour core code to see the problem.
* harbour/include/hboo.ch
* harbour/source/vm/classes.c
+ added support for new primitive message: HB_OO_MSG_PERFORM
* harbour/source/rtl/tclass.prg
- removed <lPersistent> parameter from HBClass messages and
internals data. Persistent is supported as scope bit and
separate variable was redundant.
- removed stripping of () from message names. Here is not a place
to fix wrong preprocessor rules.
* harbour/utils/hbtest/rt_class.prg
* use: METHOD PROCEDURE ... CALSS ...
instead of: PROCEDURE ... CALSS ...
The first version is preferable syntax.
* harbour/source/debug/dbgtmenu.prg
* harbour/source/rtl/checkbox.prg
! fixed some parameters in method declaration - global cleanup
will have to wait for preprocessor fixes
Hi all,
Please make test with current hbclass.ch code.
I hope that I haven't broken too much things ;-) but I rewrite
from scratch most rules and it's possible that I missed sth or
made some stupid typos. Current version is much shorter and should
be easier to updated. For sure I've intentionally changed one thing.
CLASSDATA was ignoring SHARED attribute and always created shared
class variables. Seems that it was long existing typo but the fix
may interact with already existing code which needs SHARED class
variables but does not use SHARED clause in CLASSDATA declaration.
In such case please update it and add missing SHARED.
Also in the end of CLASS declaration we have:
[ ; #translate Super( <SuperClassN> ): => ::<SuperClassN>: ] ;
[ ; #translate Super( <SuperClass1> ): => ::<SuperClass1>: ] ;
[ ; #translate Super(): => ::<SuperClass1>: ] ;
[ ; #translate Super: => ::<SuperClass1>: ] ;
[ ; #translate ::Super : => ::<SuperClass1>: ]
These rules introduce very serious bug - they are breaking supercasting
in code which makes sth like:
::super:super:super:msg
or in any other code which sends SUPER message to some other class
objects. I will have to remove them. At least the last three ones.
There were some other things I wanted to write about but it's too late
and I'm to tired - sorry. If you will have any question please ask. if
you will notice some problems with current rules please inform me.
* harbour/source/vm/classes.c
* allow to access object variables using assign messages without
parameter. I do not want to add symmetric behavior for access messages
though it's technically possible but such things should be controlled
by programmer because access messages can have less restricted scoping
then assign ones (READONLY) so I'll add new rule for it in hbclass.ch
* harbour/source/vm/hvm.c
* fixed warning message when object variable reference is
generated using macro compiler without '_' as prefix.
eg:
o:&send()
o:&send.end()
o:&(expr)()
o:&var++
o:&var := 0
o:&(expr)++
WITH OBJECT obj
++:&var
:&var += :&(var2+"oo")
END
NOTICE:
For simple assigments (=,:=), compound assignments (+=,-=,*=,/=)
and for pre/post increment operators( ++,--) the macro should
evaluate to a symbol that starts with underscore '_'.
To access a variable the macro should evaluate to a symbol
with no '_' char.
* harbour/include/common.ch
- removed ISSYMBOL()
* harbour/source/rtl/tclass.prg
