* harbour/source/rtl/hbinet.c
! fixed possible data file corruption due to wrong use of 0 handle.
0 handle is perfectly valid. By default it points to stdin but
it can be closed and then reused for any other thing, f.e. data
file. In such case any data written to socket was written to
such file and this situation was very easy to replicate with
old hbinet code.
! fixed resource leak due to unclosed handles in few cases
! fixed possible double close of the some handle what could cause
that other object handles reusing the same handle number between
first and second close (f.e. data files) was wrongly closed
! fixed s_inetRecvPattern()/HB_INETRECVLINE() - the end pattern
was wrongly checked and the code didn't detect end pattern in
streams like: "...\r\r\n" when end pattern was "\r\n"
NOTE: this code needs some general cleanup. IMHO it should be
joined with adding hbinet C API.
* source/rtl/hbinet.c
% Recently added code fixed to use HB_ERR_FUNCNAME.
! Quick fix to recently added code to compile with MSVC.
Please review, it seem that get/setsockopt() 4th parameter
is void* in Linux but char* in Windows.
* harbour/harbour-ce-spec
* harbour/harbour-w32-spec
* define whole contrib library list for new contrib/Makefile
+ added header files to respect differences between platform
native and Windows only headers

operator then Clipper/xbase
* harbour/source/rtl/hbinet.c
! fixed GPF HB_INET[GS]ET{SND,RCV}BUFSIZE() when wrong
socket parameter is passed. Please remember that after
RT error the control is returned to application.
% removed any hardcoded limits for size of data passed in
single read/write call during normal stream operations

* contrib/hbtip/client.prg
* contrib/hbtip/ftpcln.prg
* contrib/hbtip/httpcln.prg
* contrib/hbtip/mail.prg
* contrib/hbtip/sendmail.prg
+ Added methods setget to interrogate buffer size send/recive
METHOD InetRcvBufSize( SocketCon, nSizeBuff )
METHOD InetSndBufSize( SocketCon, nSizeBuff )
+ Added data members to assign default buffer sizes
DATA nDefaultRcvBuffSize
DATA nDefaultSndBuffSize
+ Asigned default buffer size to 64kb only for FTP transfer, previous to open sockets
::nDefaultSndBuffSize := 65536
::nDefaultRcvBuffSize := 65536
* Fixed port ftp protocol.
* source/rtl/hbinet.c
* now works with default system buffer, for example 8kb at W2000. instead of harcoded 1400
* harbour/include/hbclass.ch
! removed:
MESSAGE <msgName> IS <mthName>
used as synonym of:
MESSAGE <msgName> METHOD <mthName>
If someone was using the removed version then please update the
code to MESSAGE ... METHOD ...
The removed command has special meaning in Class(y) and it allow
to define alternate names for existing messages. I'll add support
for them in the future.
* harbour/contrib/hbct/ctwin.c

+ added hb_compExprReduceNegate()
! 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.

TOFIX (new): s_pOleAuto is not freed on app exit.
! Fixed a few more internal accesses by using API
calls.
; NOTE: There are four more complicated problems here
to be solved:
1) hb_stackSetActionRequest() call
2) Passing direct references to HB_ITEM .value
members to external functions.
3) Storing "hidden" information in string ITEMs
prepended after the strings' actual content.
4) Not freeing s_pOleAuto (this var BTW is used in
one static function only)

+ 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

+ 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)
