Przemyslaw Czerpak 0ef0f1aab9 2007-03-13 19:40 UTC+0100 Przemyslaw Czerpak (druzus/at/priv.onet.pl) 
* 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
      to validate if pointer item points to expected memory block type

  * harbour/source/common/hbhash.c
  * harbour/source/compiler/hbident.c
    * formatting and minor modifications

  * harbour/source/pp/pplib.c
  * harbour/source/pp/pplib2.c
    * use hb_parptrGC() to be sure that given pointer item points
      to PP structure

  + 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.

  * harbour/source/rdd/dbfcdx/dbfcdx1.c
  * harbour/source/rdd/dbfntx/dbfntx1.c
    * enabled code to seek in index using regular expressions
      (DBOI_SKIPREGEX[BACK])

2007-03-12 14:30 UTC+0100 Przemyslaw Czerpak (druzus/at/priv.onet.pl)
* harbour/include/hbexpra.c
* emulate xHarbour HB_ENUMINDEX() inside FOR EACH loop when
HB_COMPAT_XHB macro is set
It's only for compatibility - I strongly suggest to use
<unumvar>:__enumIndex()
which is more flexible and allow to chose the enumerator
variable not only the one from last loop
* harbour/include/hbexprb.c
* added comment removed from hbexpra.c
* harbour/source/compiler/hbmain.c
! fixed GPF which can appear when -b option is used in line numbering
inside codeblocks

Now new compiler library is created.
There are some things which can be improved and cleaned yet
but it's enough to create single binaries with compiler+HVM+RTLs.
I updated non GNU make files but I cannot tested the modifications
- please check and fix me if necessary

statements
* use HB_ERR_ARGS_BASEPARAMS instead of hb_paramError()
* some other cleanups and minor optimizations

directives, f.e.:
#if defined( __HARBOUR__ ) .and. !defined( HB_COMPAT_XHB )
#stdout "Harbour compiler compiled without xHarbour extensions."

* cleanup and some other minor optimizations
* harbour/source/compiler/hbopt.c
* optimize PCODEs for code like: lVar:=lVar, sVar:=sVar, mVar:=mVar, ...
* harbour/include/common.ch
* changed HB_SYMBOL_UNUSED( symbol ) to ( symbol := ( symbol ) )
It's a little bit simpler version and now it's also stripped by
PCODE optimizer
* harbour/source/compiler/harbour.c
* harbour/source/compiler/harbour.y
* harbour/source/compiler/harbour.yyc
* eliminated some redundant rules
* optimized PCODEs generated for FOR/NEXT code and removed some old
hardcoded optimization for local variables - if it will be worth
to optimize then such optimization will be done by expression
optimizer
* chaned a little bit WITHOBJECT syntax.
Now WITHOBJECT somefunc(); END is not silently ignored and call
to somefunc() is left. This optimization also works when there
are empty line between WITHOBJECT and END
* harbour/source/rdd/dbf1.c
! fixed for GPF in DBRI_RAWDATA, DBRI_RAWMEMOS (Peter Rees fix in
xHarbour)
2007-02-22 03:22 UTC+0100 Viktor Szakats (harbour.01 syenar.hu)
* harbour/source/rtl/tget.prg

2007-02-21 22:37 UTC+0100 Viktor Szakats (harbour.01 syenar.hu)
* harbour/include/common.ch
+ Changed HB_SYMBOL_UNUSED() to also work in codeblock.
Thanks to Przemek.
2007-02-18 12:40 UTC+0100 Przemyslaw Czerpak (druzus/at/priv.onet.pl)
* harbour/common.mak
* harbour/source/compiler/Makefile
* harbour/source/compiler/hbfix.c
+ harbour/source/compiler/hbopt.c
* divided hbfix.c into two separated functions:
- hb_compFixFuncPCode() which only fix generated PCODE updating
local parameters numbers when PARAMETERS is used
- hb_compOptimizePCode() which makes PCODE optimization
It allows to not execute hb_compFixFuncPCode() when PARAMETERS
is not use and execute hb_compOptimizePCode() more then once in
optimization process.
* harbour/hbgtmk.sh
* updated CVS server name
* harbour/include/hbcomp.h
* harbour/include/hbcompdf.h
* harbour/source/compiler/complex.c
* harbour/source/compiler/harbour.c
* harbour/source/compiler/harbour.y
* harbour/source/compiler/harbour.yyc
* harbour/source/compiler/hbcomp.c
* harbour/source/compiler/hbgenerr.c
* harbour/source/compiler/hbident.c
* changed code for generating in PCODE line numbers and module names
there was serious problem with line numbers and module names in old
code - in many cases line numbers were not generated at all or
generated in wrong places. Also file module name was not updated
when inside of function some code was included with #include
For such situation now modified version of HB_P_MODULE is generated
with module name only but without function name, f.e.:
HB_P_MODULE "test.prg:"
exactly the same form of HB_P_MODULE is used in xHarbour.
Debugger code should be updated to recognize such HB_P_MODULE version
Ryszard any chance that you can look at it?
And what about syncing with xHarbour debugger?
I can add some missing functions to compiler and HVM but I do not
want to update next peace of code myself. Sorry but I do not have
enough time. I'd prefer to finish some other things I'm working.
If Ryszard is busy can someone else try to port xHarbour debugger
to Harbour?
2007-02-14 00:15 UTC+0100 Przemyslaw Czerpak (druzus/at/priv.onet.pl)
* harbour/contrib/libct/ctwfunc.c
* harbour/contrib/libct/ctwin.c
* harbour/contrib/libct/ctwin.h
+ added CTWIN compatible ALERT - it works in differ way then the
standard Clipper one. In the moment when CTWIN is activated
(it's enough to call any CTWIN function like WOPEN()/WBOARD(),...
or CTWINIT()) standard ALERT() is replaced by CTWIN one build
in inside CTWIN GT driver. It allocates separate window for ALERT
box and makes differ formatting of passed text.

! 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
* moved one character length string table (hb_szAscii) from hvm.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.
* harbour/source/rtl/binnumx.c
! fixed U2BIN() - wrong casting

! 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/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

* 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"
