* rewritten code used to parse command line and environment parameters.
New code is covered by GPL + Harbour exception license.
All parameters are decoded by only one function and whole code is
smaller so it's much easier to modify this code.
! fixed some small bugs and incompatibilities with Cl*pper in parameter
parsing
! fixed -y undocumented (YYDEBUG) switch
- removed -x[<prefix>] set symbol init function name prefix (for .c only)
compiler command line switch
* moved -fn[:[l|u]|-] -fd[:[l|u]|-] -fp[:<char>] and -fs[-] switches
parsing to core compiler library. Now these switches are also works
with compiler library linked with HBMK2.
; TOFIX: HBMK2 ignores -fn/-fd switches and allocates temporary names
which are not compatible with names used later by harbour
compiler when above switches are activated. HBMK2 should
parse parameters and update SET FILECASE / SET DIRCASE before
it creates temporary files.
* src/codepage/l_fr.h
+ added 'Ç' and 'ç' characters to set of french letters
; this modification affected "FRISO" and "FRWIN" codepages.
Users using them and above characters in index field should
reindex their databases.
* include/hbcpage.hbx
* src/codepage/Makefile
* src/codepage/cpfr850.c
+ src/codepage/cpfr850c.c
* renamed "FR850" codepage to "FR850C". This is is Cl*pper ntxfre.obj
compatible codepage.
If someone uses DBF files with indexes simultaneously with Cl*pper
applications using collation order defined in ntxfre.obj the he has
to use "FR850C" codepage in Harbour.
Warning: Any users using French "FR850" codepage so far should change
the code to "FR850C".
+ added new French codepage "FR850" with all French characters and
accented equal collation rules.
; above modifications close issue #88
* include/hbznet.h
* src/rtl/hbinet.c
+ added new C function hb_znetInetTimeout()
* minor cleanup (local variables localization)
* contrib/hbssl/hbssl.hbm
* contrib/hbssl/hbssl.hbx
+ contrib/hbssl/ssl_inet.c
+ added support for SSL/TLS encryption in hb_inet*() sockets.
To enable SSL/TLS encryption on such socket it's enough to
call hb_inetSSL_connect() or hb_inetSSL_accept() passing as
1-st parameter hb_inet socket item with already established
connection and in in the 2-nd parameter SSL item. The peer
should call second function. In general hb_inetSSL_connect()
should be called by client and hb_inetSSL_accept() by server.
To use hb_inetSSL_accept() it's necessary to also set
certificated (at least self ;-)) encryption keys. See the
example I committed to test directory.
The exact syntax of new functions is:
hb_inetSSL_connect( <pSocket>, <pSSL> [, <nTimeout> ] )
hb_inetSSL_accept( <pSocket>, <pSSL> [, <nTimeout> ] )
To use hb_inet*() functions to connect with SSL/TLS server
Harbour users only have to call hb_inetSSL_connect() after
setting connection, i.e.:
IF !Empty( sock := hb_inetConnect( cServer, nPort ) )
ssl_ctx := SSL_CTX_new()
IF hb_inetSSL_connect( sock, SSL_new( ssl_ctx ) ) == 1
// SSL connection established
// now user can use all hb_inet*() functions is
// the same way as for raw TCP connections and
// all parameters like timeouts are fully supported
// but transmission is encrypted.
[...]
ENDIF
ENDIF
It's not longer necessary to use SSL_set_fd() + SSL_connect()
and then SSL_read() / SSL_write() / hb_SSL_read_line() /
hb_SSL_read_all().
BTW hb_SSL_read_line() and hb_SSL_read_all() in HBSSL library
are broken and have to be fixed.
TODO: Now HBTIP library can be nicely simplified and additional
code for SSL/TLS read/write operations removed. It's
enough to once call hb_inetSSL_connect() if SSL/TLS
encryption is needed.
+ contrib/hbssl/tests/inetssl.prg
+ added test code for hb_inet*() SSL/TLS connections.
It's client and server example which also generates self
certificated encryption keys running openssl command.
If this code is linked with non console GT then user
should generated certificates himself (see comment in
LoadCertificates() function for more information).
* include/harbour.hbx
* src/vm/hvm.c
+ added new PRG function:
__BreakBlock() -> {|e| Break( e ) }
* include/hbexprb.c
% replace {|e| Break( e ) } with __BreakBlock() function call.
__BreakBlock() returns exactly the same codeblock on each call
so using it save memory and improve a little bit speed because
it's not necessary to allocate new GC memory block and register
it in GC block list. Additionally in MT mode it eliminates mutex
lock necessary to register new GC block.
* include/hbznet.h
* src/rtl/hbinet.c
* src/rtl/hbinetz.c
* moved HB_INET_ERR_* macros to header file
+ added error and errorStr functions to hb_inet*() socket read/write
wrappers

; (2014-12-19 01:00 UTC+0100 Viktor Szakats)
! HBGetList():GUIApplyKey(): fixed bug introduced with UNICODE
support in 93d3a46d84 (upstream).
That patch had an undocumented workaround for the problem inside
ListBox():findText(), which was not Cl*pper compatible, so
it was later removed in 6f8508ff54a3955822b36bf4a65a2775a11bab23.
This patch hopefully fixes the root cause.

! ListBox():findText(): fixed to allow zero length search text,
like Cl*pper. Regression from 93d3a46d84
! ListBox():addItem( cText, cData ): fixed to allow any type for cData,
not just NIL and string, like Cl*pper
+ ListBox():setData(): documented a Cl*pper bug
; 2014-03-09 18:19 UTC+0100 Viktor Szakáts
! ListBox():scroll() fixed to ignore non-numeric parameter

(work in progress)
* formatting
* include/hbrddcdx.h
* src/rdd/dbfcdx/dbfcdx1.c
* added support for user defined index page size in DBFCDX.
To change page size for newly created index it's enough to call:
hb_rddInfo( RDDI_INDEXPAGESIZE, <nNewSize>,, "DBFCDX" )
DBFCDX accepts page sizes which are power of 2 in from 512 to 8192.
The upper range is my personal decision and can be easy changed
in Harbour source code. 512 is default CDX index page size and
only such indexes can be read by other RDDs.
In some cases bigger pages can increase performance and reduce
index size. In local networks probably 1024 should give optimal
performance because can be transferred in single ethernet frame.
Just make a tests.
; In next step I plan to add support for longer index keys when
bigger pages are used.
* utils/hbmk2/hbmk2.prg
! added -stop fix borrowed from Viktor's branch
* include/hbrddcdx.h
* src/rdd/dbfcdx/dbfcdx1.c
+ added support for large index files over 4GB length.
These are slightly modified CDX indexes which stores index page numbers
instead of index page offsets inside index file. This trick increase
maximum index files size from 2^32 (4GB) to 2^41 (2TB). This index
format is enabled automatically when DB_DBFLOCK_HB64 is used. This is
the same behavior as in DBFNTX and DBFNSX for which I added support
for large indexes (up to 4TB) few years ago.
Warning: new CDX indexes are not backward compatible and cannot be
read by other systems or older [x]Harbour versions.
If you try to open new indexes using older [x]Harbour RDDs
then RTE "DBFCDX/1012 Corruption detected" is generated.
When current Harbour *DBFCDX/SIXCDX RDD open index file
then it automatically recognize type of index file so it
will work correctly with both versions without any problem.
In short words: People using DB_DBFLOCK_HB64 should remember
that after reindexing with new Harbour applications old ones
cannot read new CDX indexes.
; In next step I plan to add support for user defined page size in CDX
index files.
* doc/xhb-diff.txt
* added information about extended CDX format to section "NATIVE RDDs"
* src/rdd/dbfcdx/dbfcdx1.c
* src/rdd/dbfnsx/dbfnsx1.c
* src/rdd/dbfntx/dbfntx1.c
* disable record readahead buffer used during indexing when only
one record can be stored inside
! generate RTE when data cannot be read into record readahead buffer
during indexing
* include/hbdefs.h
* use strict aliasing friendly conversions in MSC builds which support
intrinsic version of _byteswap_*() functions.
It should also pacify some of MSC warnings.
* include/hbdefs.h
* src/rdd/dbffpt/dbffpt1.c
* minor formatting
* contrib/gtwvg/wvgcore.c
! fixed HANDLE to LONG casting - it's bug in 64 bit builds
* include/hbcomp.h
* include/hbcompdf.h
* src/compiler/hbmain.c
* src/compiler/harbour.y
* src/compiler/harbour.yyc
* replaced 'char' type holder with 'HB_BYTE' - this is part of never
finished code which is completely dummy in current compiler and above
modification is only to pacify warnings which are real bugs in existing
implementation. I do not plan to modify or fix this code. I'll remove
it working on fully functional strong typing implementation.
* include/hbapi.h
* src/common/hbstr.c
+ added new function hb_strAtI() - it works like hb_strAt() but it
ignores the case of the ASCII characters
* src/rtl/ati.c
* renamed local static function hb_strAtI() to s_strAtI() to avoid
conflict with new public hb_strAtI() function.
* contrib/xhb/xhbat.c
- removed local static function hb_strAtI() - current public hb_strAtI()
is compatible with it.
* contrib/sddsqlt3/core.c
+ added new code to set column type giving the highest priority SQLITE3
declared column types.
Please test - I haven't made any.
! do not cast floating point values to integer
* contrib/hbwin/hbwin.hbx
* contrib/hbwin/win_prn2.c
! fixed win_printerGetDefault() in Win9x builds - fix and some
formatting and casting borrowed from Viktor's fork.
+ added new PRG function:
win_PrintDataRaw( <cPrinter>, <cData> [, <cDocName>] )
-> <nBytesPrinted>
It's similar to win_PrintFileRaw() but sends to given printer passed
in 2-nd parameter <cData> instead of file body.
On error it returns negative value.
* cleaned casting and minor formatting
* src/rtl/gtxwc/gtxwc.c
+ added support for HB_GTI_DISPIMAGE. It's slightly modified code sent
by Rolf to Harbour devel list. In comparison to original version it
supports <nDepth> as 4-th item of array with bitmap description to use
with some other GTs which can support different color depths or can
make conversion. It also supports bitmaps passed as strings.
% slightly improved HB_GFX_GETPIXEL
* include/hbdebug.ch
+ added HB_DBG_* constant values for arrays returned by __dbg*()
functions
* include/hbset.h
* src/vm/set.c
+ added new C function: hb_setGetItem();
* src/debug/dbgentry.c
* use HB_DBG_* constant values
+ added new debugger function: __dbgGetSETs() - it returns array with
all HVM SETs: { { <nSet>, <cSetName>, <xSetValue> }, ... }
% optimized hb_dbgActivateCallStackArray() and hb_dbgActivateModuleArray()
* src/debug/debugger.prg
* use HB_DBG_* constant values
* use __dbgGetSETs() for "System Settings" window
+ added support for Harbour SET extensions
* ChangeLog.txt
* updated description for structure of array returned
by __dbgGetBreakPoints()
* include/hbvm.h
* src/vm/hvm.c
+ added new HVM function: hb_vmTryEval()
This function tries to execute given block or function
inside BEGIN SEQUENCE / RECOVER oErr / END SEQUENCE statement.
It return HB_TRUE if it was executed without any problem and
HB_FALSE otherwise. Result or RTE object is stored in 1-st
parameter and should be freed by the caller using hb_itemRelese()
* src/debug/dbgentry.c
! use hb_vmTryEval() instead of hb_itemDo() to evaluate trace point
expressions. Now debugger does not crash when user sets tracepoint
expression which cannot be evaluated in executed context.
! allow to use expressions with more then 99 variables
! added missing protections against GPF when wrong parameters are
passed to __dbg*() functions
* keep original trace and watch point expression for farther
processing
* replaced IS_IDENT_*() macros with HB_IS*IDCHAR()
+ added new debuger function:
__dbgGetWatchPoints() -> <aWatchTracePoints>
<aWatchTracePoints> contains subarrays describing trace and watch
points:
{ <cExpression>, <lTracePoint>, <lValid>, <xResult> }
It was the last function necessary to extract all information
about debugged context from core internals. Now it's possible
to create fully functional standalone debugger without storing
and updating locally any information about debugger state.
All such information can be accessed at any time using __dbg*()
functions.
It should greatly simplify creating 3-rd party debuggers like
HWDebug or HBQTDebug.
* src/debug/debugger.prg
! fixed callstack window updating during tracing and stepping.
Tanks to Rolf for reporting the problem.
* contrib/hbct/ctwin.c
! fixed typo in window area checking when current window is 0
It fixes problem with debugger reported by Rolf.
* src/debug/dbgentry.c
% few optimizations
! added few protections against GPF when wrong parameters are passed
! fixed missing support for symbol, date and timestamp values in
tracepoints
+ added __dbgCntWatch()
* src/rtl/filesys.c
* src/rtl/hbproces.c
* pacified warning in more aggressive way for newer GCC versions
* include/harbour.hbx
* refreshed
* include/harbour.hbx
* src/rtl/val.c
+ added new function: hb_Val( <cStr> [, <nLen> ] ) -> <nVal>
it works like a val but set length for numeric result to passed string
length or <nLen> parameter if is large enough.
* src/rtl/tget.prg
! use hb_Val() instead of Val() for numeric GETs to replicate Clipper
behavior for pictures longer then 10 characters.
* include/hbserial.ch
* src/rtl/itemseri.c
+ added HB_SERIALIZE_IGNOREREF flag.
This flag fully disables logic used to detect multireferences to the
same complex (sub)items like arrays or hashes. It increses the speed
of serialization but serialized data does not contain any information
about refences, i.e. aVal[ 1 ] and aVal[ 2 ] in code below:
aSub := { 1, 2, 3 }
aVal := { aSub, aSub }
are serialized as separated arrays. Additionally items with cyclic
references like:
aSub[ 2 ] := aSub
cannot be serialized at all with HB_SERIALIZE_IGNOREREF flag because
it will create infinite serialization loop and crash with out of
memory message.
* src/rtl/itemseri.c
% rewritten algorithm used to detect cyclic and multi references in
serialized items. The original algorithm has very high overhead when
huge arrays were serialized, i.e. serialization of array with 1'000'000
of subarrays needed about 30 minutes on my i5@3.30GHz. Now it needs
less then a second and this time is only a little bit bigger then
used by serialization with HB_SERIALIZE_IGNOREREF flag.
This modification improve performance also in other code using Harbour
serialization mechanism like I18N files, HBNETIO, GTNET, ... when large
arrays or hashes are saved or transmitted.
* include/hbapi.h

* src/vm/arrays.c
* src/vm/classes.c
* src/vm/hashes.c
* src/vm/itemapi.c
* replaced algorithm used to detect cyclic and multi references in
array and hash clone operations with new one similar to current
item serial code. The speed improvement for very large arrays is
the same as in case of serialization code.
* src/rtl/gtsln/mousesln.c
! typo in while loop - synced with Viktor's branch
* contrib/hbwin/olecore.c
+ added some additional error codes to win_oleErrorText() function
* contrib/hbwin/hbole.ch
+ added OLE error code definitions with WIN_* prefix for errors returned
by win_oleErrorText()
* contrib/xhb/xhb.hbx
* contrib/xhb/xhbole.prg
+ aded new function OleDefaultArg()
% minor simplification
* src/rtl/itemseri.c
* do not generate RTE when wrong string is deserialized.
Now RTE 3016 is generated only when compressed data is deserialized
and ZLIB is not linked with final binaries so users can easy locate
the source of problem.

! fixed GET colors when _SET_INTENSITY == .F.
2014-04-22 02:35 UTC+0200 Viktor Szakats
% use Stuff() instead of different combinations of Left() and SubStr()
* include/harbour.hbx
* src/rtl/left.c
+ added new function to replace "=" operator without the SET EXACT ambiguity
in its most common pattern of usage:
hb_LeftEq( <cString1>, <cString2> ) -> <lResult>
it's equivalent to this expression, but faster and shorter:
( Left( <cString1>, Len( <cString2> ) ) == <cString2> )
2014-01-22 03:09 UTC+0100 Viktor Szakáts
+ added hb_LeftEqI(). Same as hb_LeftEq() but case-insensitive.
hb_LeftEqI( <cString1>, <cString2> ) -> <lResult>
2014-02-04 13:38 UTC+0100 Viktor Szakáts
* include/harbour.hbx
* src/rtl/chruni.c
+ added hb_BRAt(). Same as hb_RAt() but for raw/binary strings

* contrib/hbsqlit3/core.c
* pacified some of -Wshadow warnings
* include/hbapicdp.h
! typo in comment: bytes -> bits
* src/vm/garbage.c
* src/vm/thread.c
* disabled some code with spinlocks when HB_HELGRIND_FRIENDLY macro
is defined. It causes that final MT HVM code is slower using native
platform mutexes but only such ones helgrind can recognize so the
new macro can be useful for people who want to make some tests with
helgrind. In such case they should rebuild Harbour with
HB_USER_CFLAGS=HB_HELGRIND_FRIENDLY
We use spinlocks and atomic integer operations also in few other
places so it's possible that deeper tests can exploit them and
we will have to cover them by HB_HELGRIND_FRIENDLY too just to
easy detect real problems.
* src/rtl/filebuf.c
! unlock HVM stack before locking local mutex and calling hb_fs*()
functions which also unlocks HVM. It fixes possible deadlock condition
when hb_gcAll( .T. ) is executed.
* include/hbapi.h
* src/vm/garbage.c
! changed mark function semantic.
Adding support for user defined mark function I created race condition
in MT GC code. It happens because blocks marked as deleted were not
scanned by GC mark code so their subitems where not accessible.
To fix it we have to change mark function semantic. Now mark function
can be executed also for blocks currently deleted. It means that GC
block destructor should clean references to just removed items and
subblocks. The best place to make it is clearing pointers to GC blocks
just after hb_itemRelease() or hb_gcRefFree().
It is save to clean the reference just before hb_itemRelease() or
hb_gcRefFree() but only for the single block passed to these functions.
It is not save to clear reference to more then one block and then
execute above functions.
+ check reference count after destructor execution for all blocks
not only arrays - warning it may exploit some wrong C code.
- removed not longer used hb_gcRefCheck() function.
* include/hbvm.h
* src/vm/hvm.c
+ added new internal function hb_vmLockForce()
! fixed to mark GC blocks with active threads
* src/vm/thread.c
* include/hbthread.h
% modified sync mutexes used by xBase++ signal class emulation
to not use item array internally
* updated mutex destructor to new GC mark semantic
! mark GT items if GT is bound with thread item
! fixed mutex notify/subscribe code to not change GC items
when HVM stack is unlocked
! use hb_vmLockForce() to eliminate potential deadlock
+ added new C function hb_threadEnterCriticalSectionGC().
It should be used instead of hb_threadEnterCriticalSection()
in code which manipulates GC items inside critical section.
It's slower but eliminates possible deadlock condition.
Please remember that remember that both functions cannot
be used for the same mutex. So if it's necessary to use
hb_threadEnterCriticalSectionGC() in one place then it
has to be used in all others when the same mutex is locked.

* contrib/hbexpat/core.c
* updated destructors to new GC mark semantic
* contrib/hbxpp/dllx.c
! fixed destructor for pointer item created by DllPrepareCall()
Now it respects reference counter.
; added note about real behavior of library handle destructor,
I haven't changed existing code behavior but maybe it should
be done.
* contrib/xhb/hbserv.c
* src/debug/dbgentry.c
* src/rdd/wacore.c
! fixed possible deadlocks by using hb_threadEnterCriticalSectionGC()
instead of hb_threadEnterCriticalSection().
* contrib/hbmemio/memio.c
! slightly modified hb_memfsDirectory() code to avoid race condition
without using hb_threadEnterCriticalSectionGC()
* src/vm/fm.c
% reduce the lock range in HB_FM_STAT builds
* src/rtl/hbsocket.c
! added missing HVM stack unlocking in hb_socketSelect() function
* src/rtl/gtxwc/gtxwc.c
! added few missing locks for version compiled with HB_XWC_XLIB_NEEDLOCKS
* src/rdd/dbtotal.prg
* allow to use symbols instead of codeblocks
* modified Harbour extension which uses ordKey() as default group
signature to work also without index. In such case all records
are summarized into single one.
; Most of above modifications were critical for stability of MT programs.
They should allow to activate GC in any place.
* include/Makefile
+ include/hbiousr.ch
* src/rtl/Makefile
+ src/rtl/iousr.c
+ added module for writting Harbour FILE IO redirectors at PRG level
+ tests/iotcp.prg
+ example code for FILE IO redirector written in PRG.
It's IOTCP and gives exactly the same functionality as TCP redirector
in contrib which is written in C.
* src/vm/runner.c
% modified internal structure to eliminate some memory allocations
* contrib/hbpgsql/rddcopy.c
% small simplification

* contrib/hbmemio/memio.c
* contrib/hbnetio/netiocli.c
* contrib/hbtcpio/tcpio.c
* changed internal FILE IO API. Now all functions which do
not operate on PHB_FILE receive pointer to function table
(PHB_FILE_FUNCS) used by given redirector.
* src/rtl/vfile.c
* open wirtual files in READWRITE mode by default
* translate FO_* attributes to FXO_* ones
* src/vm/classes.c
! fixed typo in RTE message
* src/vm/garbage.c
* use different error code (1301/1302) for destructor RTE
* src/rtl/gtxwc/gtxwc.c
* src/rtl/gtxwc/gtxwc.h
+ added support for HB_GTI_FONTWEIGHT with HB_GTI_FONTW_* actions
* contrib/hbpgsql/rddcopy.c
! fixed memory leak
% encapsulate PQ calls in hb_vmUnlock()/hb_vmLock() to not stop
other threads when GC is activated
* include/hbapifs.h
* src/rtl/filebuf.c

hb_fsGetFileTime()
* include/hbapifs.h
* src/rtl/vfile.c
+ added C functions to manipulate PRG level hb_vf*() file pointer items
* include/hbapifs.h
* src/rtl/filebuf.c

+ added C functions to check if file IO handle points to local file
* contrib/hbmzip/mzip.c
* changed hb_fs*() API to hb_file*() API
! fixed file time setting in *nix builds
* contrib/hbtcpio/tcpio.c
* use default timeout defined in initial hostname string in read/write
operations
* include/hbapicom.h
* src/rtl/hbcom.c
+ added new C function:
int hb_comFindPort( const char * pszDevName, HB_BOOL fCreate );
It check if given port name is already defined and if not and second
parameter fCreate is TRUE then it allocates such port in one of last
free slots. On success port number is returned. If port cannot be
found or created 0 is returned.
* include/harbour.hbx
* src/rtl/hbcomhb.c
+ added new PRG function:
hb_comFindPort( <cDeviceName> [, <lCreate> = .F. ] ) -> <nPort>
* contrib/hbplist.txt
+ contrib/hbcomio/comio.c
+ contrib/hbcomio/hbcomio.hbc
+ contrib/hbcomio/hbcomio.hbp
+ added new Harbour FILE IO redirector.
It recognizes and process names with "COM<n>:" prefix, in form like:
COM<n>:[<com_params>]
<n> is port number or port name prefixed with "$" character.
<com_params> may contain serial port parameters like baud rate, stop
and data bits, parity and flow control (XON,XOFF,CTS, RTS,DST,DTR).
As delimiter comma "," is accepted.
This redirector can be used in different subsystems using Harbour
FILE IO and stream read/write operations, i.e.
REQUEST HB_COMIO
SET PRINTER TO COM2:38400,N81,XONXOFF
can be used to connect to serial printers.
Please remember that redirectors like NETIO can be used as wrapper
to other redirectors so code like:
pFile := hb_vfOpen( "NET:192.168.0.1:::COM1:9600,8N1" )
opens 1-st serial port on the server and
pFile := hb_vfOpen( "NET:192.168.0.1:::COM$/dev/ttyUSB0:9600,8N1" )
opens "/dev/ttyUSB0" serial device on the server.
* src/vm/set.c
! fixed freed memory access exploited by interactions between
modifications in last few years.
! do not try to remove trailing ^Z char reading from the stream
if FS_END seek reports 0.
! if possible open printer/alternate/extra output in write only mode
to avoid problem on devices where read access is not available.
* src/rtl/langapi.c
* keep EN lang active after deinitialization
* src/rtl/filesys.c
! fixed condition for file time refresh in *nix builds
! fixed file time setting in *nix builds
* include/hbapifs.h
* src/rtl/Makefile
* src/rtl/filebuf.c
+ src/rtl/filebufd.c
* renamed hb_fileRegister2() to hb_fileRegisterFull()
+ added new function hb_fileRegisterPart() which simplifies writing
small FILE IO redirectors.
* contrib/hbmemio/memio.c
* contrib/hbnetio/netiocli.c
* use hb_fileRegisterFull()
* contrib/hbplist.txt

+ contrib/hbtcpio/hbtcpio.hbp
+ contrib/hbtcpio/hbtcpio.hbx
+ contrib/hbtcpio/tcpio.c
+ added new Harbour FILE IO redirector.
It recognizes and process names with "tcp:" prefix, in form like:
tcp:<host>:<port>[:<timeout>]
It can be used in different subsystems using Harbour FILE IO and
stream read/write operations, i.e.
REQUEST HB_TCPIO
SET PRINTER TO tcp:192.168.0.110:9100
can be used to connect to network printers using TCP direct printing.
* utils/hbmk2/po/hbmk2.pt_BR.po
! fixed typo in translation
* include/hbchksum.h
* src/rtl/hbmd5.c

- src/rtl/xfile.c
+ src/rtl/vfile.c
* renamed PRG functions HB_X*() to HB_VF*()
* renamed PRG functions hb_vf[GS]etAttr() to hb_vfAttr[GS]et()

* contrib/hbnetio/netiosrv.c
+ added support for redirecting hb_vfConfig() to the server.
NETIO does not use it anyhow NETIO works as full redirector
to server system and it may be used on the server side.
* include/hbapifs.h
* src/rtl/filebuf.c
+ added new C function hb_filePOpen()
* include/hbset.h
* src/vm/set.c
* src/rtl/console.c

* src/rtl/filesys.c
! report EOF in hb_fsEof() also when file position is out of file size
* updated comment
* include/hbapifs.h
* src/rtl/filebuf.c
+ extended Harbour FILE IO API and added support for read/write filepos,
directory and link operations.
Read/write filepos support in some systems (i.e. *nixes) needs additional
emulation code. If it's not necessary then this functionality can be
disabled by FXO_NOSEEKPOS attribute. Now this attribute is used by our
RDD code.
* src/rtl/Makefile
+ src/rtl/xfile.c
+ added PRG interface to Harbour FILE IO API
The following PRG functions are available for Harbour programmers:
HB_XEXISTS( <cFileName>, [ @<cDestFileName> ] ) -> <lOK>
HB_XERASE( <cFileName> ) -> <nResult>
HB_XRENAME( <cFileSrc>, <cFileDst> ) -> <nResult>
HB_XCOPYFILE( <cFileSrc>, <cFileDst> ) -> <nResult>
HB_XDIREXISTS( <cDirName> ) -> <lExists>

HB_XLINKREAD( <cFileName> ) -> <cDestFileName> | ""
HB_XOPEN( <cFileName>, [ <nMode> ], [ <nAttr> ] ) -> <pHandle> | NIL
HB_XCLOSE( <pHandle> ) -> <lOK>
HB_XLOCK( <pHandle>, <nStart>, <nLen>, [ <nType> ] ) -> <lOK>
HB_XUNLOCK( <pHandle>, <nStart>, <nLen> ) -> <lOK>
HB_XLOCKTEST( <pHandle>, <nStart>, <nLen>, [ <nType> ] ) ;
-> <nPID> | 0 (nolock) | -1 (err)
HB_XREAD( <pHandle>, @<cBuff>, [ <nToRead> ], [ <nTimeOut> ] ) ;
-> <nRead>
HB_XWRITE( <pHandle>, <cBuff>, [ <nToWrite> ], [ <nTimeOut> ] ) ;
-> <nWritten>
HB_XREADAT( <pHandle>, @<cBuff>, [ <nToRead> ], [ <nAtOffset> ] ) ;

HB_XEOF( <pHandle> ) -> <lEOF>
HB_XFLUSH( <pHandle>, [ <lDirtyOnly> ] ) -> NIL
HB_XCOMMIT( <pHandle> ) -> NIL
HB_XCONFIG( <pHandle>, <nSet>, [ <nParam> ] ) -> <nResult>
HB_XHANDLE( <pHandle> ) -> <nOsHandle>
HB_XTEMPFILE( @<cFileName>, [ <cDir> ], [ <cPrefix> ], [ <cExt> ], ;
[ <nAttr> ] ) -> <pHandle> | NIL
Please remember that not all redirectors have to support all of them.
I.e. MEMIO allows to use directory names in files but does not allow to
create or remove directories. It also does not support file attributes
and times in current implementation though it can be easy added.
HB_XCONFIG() is general function which can be used by redirector
authors to make some special operations which are specific to given
device.
HB_XTEMPFILE() always creates temporary files on local system without
switching to FILE IO redirector. It's intentional behavior.
* src/rtl/fscopy.c
* used Harbour FILE IO API in hb_fsCopy()/HB_FCOPY()
Please remember that HB_FCOPY() always makes operation using current
system when HB_XCOPY() may optimize it moving the operation to low
level subsystem or even other computer i.e. NETIO can do that when
both files are located on the same server.
* src/rdd/delim1.c
* src/rdd/sdf1.c
* src/rdd/dbf1.c
* src/rdd/dbfcdx/dbfcdx1.c
* src/rdd/dbffpt/dbffpt1.c
* src/rdd/dbfnsx/dbfnsx1.c
* src/rdd/dbfntx/dbfntx1.c
* src/rdd/hsx/hsx.c
* open files with FXO_NOSEEKPOS attribute to inform low level API that
read/write filepos is not used (disables unnecessary filepos emulation).
* contrib/hbnetio/netio.h
* contrib/hbnetio/netiocli.c
* contrib/hbnetio/netiosrv.c
+ added support for extended Harbour FILE IO API.
* contrib/hbnetio/utils/hbnetio/netiomgm.hb
! renamed "quit" command to "shutdown" as suggested by Rolf.
* contrib/hbnetio/utils/hbnetio/hbnetio.prg
* allow to interrupt server process using ESC when run in console window.
* contrib/hbmemio/memio.c
+ added support for extended Harbour FILE IO API.
I left two minor TODO notes - maybe someone will try to implement it.
