* harbour/contrib/hbct/screen2.c
! fixed possible vary bad bug (memory buffer overflow) in SCREENSTR()
* harbour/source/rtl/hbffind.c
! fixed possible GPF in some *nixes
* harbour/source/vm/classes.c
! do not execute the same destructor inherited from different parent
classes more then once
* harbour/source/rtl/transfrm.c
! fixed bug with '9' used as stop condition of function pattern
this character cannot be stripped, f.e.:
? transform( "abc", "@_99*" )
! fixed bug with '*' or '$' used with @), f.e.:
? transform( -12345, "@) $999999" )
! fixed replacing '.' with ',' when @E is used without picture part, f.e.:
? transform( 123.45, "@E" )
! fixed ',' conversions
? transform( 12.34,"@E ab,cd.ef9,9.99,.--" )
! fixed bug with picture starting with ".", f.e.:
? transform( 0.3456, ".999" )
! fixed "@(" and "@)" conversions, f.e.:
? transform( -12345, "@) 1999*999" )
! fixed late oveflow detection in "@(" and "@)", f.e.:
? transtest( -12345, "@( 6798^999" )
! fixed "@E" conversion for dates to keep user delimiters set in
_SET_DATEFORMAT, f.e.:
set( _SET_DATEFORMAT, "mm:dd:yyyy" ); ? transform( date(), "@E" )
set( _SET_DATEFORMAT, "yyyy<mm>dd" ); ? transform( date(), "@E" )
Please note that Harbour is not strictly Clipper compatible here
because it respects _SET_DATEFORMAT set by user.
! fixed 64bit integer conversion by eliminating conversion to
'double' f.e.:
? transform( 1234567890123456789, "99999999999999999999" )
? transform( -1234567890123456789, "99999999999999999999" )
! some other fixes, see regression test transtst.prg
% speed improvement in numeric conversions
+ harbour/tests/transtst.prg
+ added regression test for transform function
* harbour/utils/hbtest/rt_trans.prg
* disabled transform() tests for "@E" and result smaller then 5 bytes
CA-Cl*pper do not check result size and always exchanges
bytes 1-2 with bytes 4-5 for @E conversion. It's buffer overflow
bug and I do not want to replicate it inside our transform
implementation. It also causes that the results for for strings
smaller then 5 bytes behaves randomly.
In fact precise tests can show that it's not random behavior
but CA-Cl*pper uses static buffer for result and when current one
is smaller then 5 bytes then first two bytes are replaced with
4-5 bytes from previous result which was length enough, f.e.:
? transform( "0123456789", "" )
? transform( "AB", "@E" )
? transform( "ab", "@E" )
Replicating exact CA-Cl*pper behavior it's trivial (it will be enough
to use static buffer two and not check the size of current result) but
IMHO it's bug.
* harbour/source/rtl/round.c
* added strictly Clipper compatible code covered by HB_C52_STRICT
and comment about possible difference in Harbour.
* harbour/include/hbgtinfo.ch
* harbour/source/rtl/hbgtcore.c
* harbour/source/rtl/gtxwc/gtxwc.c
* harbour/source/rtl/gtsln/gtsln.c
* harbour/source/rtl/gttrm/gttrm.c
* harbour/source/rtl/gtwvt/gtwvt.c
+ added HB_GTI_ISUNICODE - it returns logical value with information
about Unicode mode in active GT driver - it's necessary for proper
CP initialization in some GTDs which can work in both mode depending
on client side settings
* harbour/source/rtl/gttrm/gttrm.c
* improved UTF-8 detection
* added automatic PuTTY detection
* improved PuTTY and some xterm key handling
* added some missing RXVT keys
best regards,
Przemek
