* include/Makefile
+ include/hbzlib.h
* include/hbzlib.ch
* src/rtl/Makefile
* src/rtl/hbzlib.c
+ added new C functions weakly bound with ZLIB library:
HB_SIZE hb_zlibCompressBound( HB_SIZE nLen );
HB_SIZE hb_zlibUncompressedSize( const char * pSrc, HB_SIZE nLen,
int * piResult );
int hb_zlibCompress( char * pDst, HB_SIZE * pnDst,
const char * pSrc, HB_SIZE nLen, int iLevel );
int hb_zlibUncompress( char * pDst, HB_SIZE * pnDst,
const char * pSrc, HB_SIZE nLen );
these functions can be used by any C code without forcing ZLIB liking.
If user usese in his code HB_ZCOMPRESS() function or has
REQUEST HB_ZCOMPRESS
then above funcitons are automatically bound with linked ZLIB library.
Otherwise they return 0 or HB_ZLIB_RES_UNSUPPORTED error.
* src/rdd/dbf1.c
* small code simplification
; added note about alternative numeric value rounding when
pure binary integer fields (without decimal places) are
assigned.
* src/common/hbdate.c
! added missing header for WinCE builds
* include/hbexpra.c
* minor simplification
* src/vm/macro.c
+ added new implementation for MemVarBlock() function. It's much faster
and does not force dynamic symbol table scanning on each call
* src/rtl/Makefile
- src/rtl/memvarbl.prg
- removed previous implementation of MemVarBlock()
* src/rtl/tgetint.prg
! fixed __Get() and __GetA() to return NIL when cVarName parameter
is not string (CA-Cl*pper compatible)
! fixed __GetA() to return NIL when given aIndex parameter or value
returned by variable block is not array (CA-Cl*pper compatible)
! fixed __Get() and __GetA() to use FieldWBlock() instead of manually
created macro block which didn't respect workarea
(CA-Cl*pper compatible)
! fixed __GetA() to create SET/GET block instead of access block
(CA-Cl*pper compatible)
! fixed __Get() and __GetA() to not create simple SET/GET macro
blocks but always force memvar usage (CA-Cl*pper compatible).
Please remember that
&( "DATA" )
gives code which tries to access field then memvar but
&( "DATA := .T." )
gives code which always tries to assign memvar and does not even
check if "DATA" field exists in current WA. It means that macro
compiled code like:
&( "{|_1| iif( _1 == NIL, DATA, DATA := _1 ) }" )
should not be used because gives higher priority for fields in
access operation and always assigns memvars, if necessary creating
them.
! allow to dynamically create memvars for get objects in error handler
(CA-Cl*pper compatible)
% use much faster MemVarBlock() instead of manually created codeblock
which activates dynamic symbol table scanning on each call
