! allow to use dbSetFilter() with string only parameter without
codeblock - Cl*pper compatibility fix.
Cl*pper allows to set text filter without codeblock. In local
RDDs it effectively does nothing and only dbFilter() returns it
but RDDs with automatic filter optimization like CL53/DBFCDX /
COMIX/ClipMore or RDDs working with remote data base servers
may use only text version of filter and ignore or use with
lower priority the codeblock so Harbour has to work like
Cl*pper here.

* src/common/hbfsapi.c
+ added automatic file handle table resizing to hb_fsOS2DosOpenL()
+ added new C function: hb_fsOS2DosOpen() which is wrapper to DosOpen()
with automatic file handle table resizing.
Please remember that unlike hb_fsOS2DosOpenL() this function is
pure wrapper to DosOpen() so it does not make file name conversions
and does not set hb_fsError().

* minor cleanup
* include/hbmemory.ch
* src/vm/fm.c
+ added two new actions for Memory() function:
HB_MEM_STATISTICS - return non 0 value if FM statistic is enabled
HB_MEM_ISLIMIT - return non 0 value if used memory limit is
supported
+ added new PRG function:
__fm_allocLimit( [ <nNewLimit> ] ) -> <nPrevLimit>
It allows to set limit for maximum used memory in some memory
managers, -1 means no limit.
Now it works with DLMALLOC and in ST mode it's limit for memory
allocated from system for whole application. In MT mode when
HB_FM_DLMT_ALLOC (default for DLMALLOC) is enabled it's limit for
single MSPACE (Harbour allocates 16 MSPACES and balance them
between threads to improve scalability) so it's rather per thread
limit. If memory statistic module is enabled during Harbour build
process then this limit works with any memory manager and defines
limit for total memory allocated by Harbour application regardles
of MT or ST mode.
* src/vm/hvm.c

HB_BOOL bForceExact, int * piResult );
For compatible types it compares pItem1 with pItem2 setting piResult
to -1, 0 or 1 if pItem1 is <, == or > then pItem2 and returns true
otherwise it returns false and does not touch piResult.
+ allow to compare symbol items in hb_itemEqual()
* include/hbrdddel.h
* src/rdd/delim1.c
+ added to DELIM RDD support for defined by user default filename
extenssion. It can be changed by:
hb_rddInfo( RDDI_TABLEEXT, ".csv", "DELIM" )
+ added to DELIM RDD support for exporting initial record with field
names. It can be enabled by:
hb_rddInfo( RDDI_SETHEADER, 1, "DELIM" )
and disabled by:
hb_rddInfo( RDDI_SETHEADER, 0, "DELIM" )
Importing from CSV files with such header is not supported yet but
I plan to add it so in the future RDDI_SETHEADER=1 will also effect
import (APPEND FROM).

Now LF, CRLF, CR and LFCR EOLs are supported and automatically
recognized during import if one of such EOLs is also set in HVM by
_SET_EOL.
% use 8192 bytes read ahead buffer to speed up import from DELIM and
SDF RDDs
+ modified file IO operations to work with stream only (no support for
file seek) Harbour File IO drivers
% optimized some File IO operations
* strip all EOF (^Z) characters from imported data. It's not strictly
Cl*pper compatible because Cl*pper interrupts import on first ^Z
character anyhow it was always the source of problems when .txt
files are concatenated by tools like 'cat' in *nixes so I decided
to change it.
+ added support RECORD clause command in commands like:
APPEND FROM "data.txt" RECORD (nRec) DELIMITED
APPEND FROM "data.txt" RECORD (nRec) SDF
It's Harbour extension - Cl*pper does not support it.
+ generate RTE when some unsupported in transfer RDDs methods are
called
* include/harbour.hbx
* src/vm/hvm.c

* src/rdd/dbf1.c
! fixed detecting VFP tables broken in my previous
modification - thanks to Mario H. Sabado for information
about the problem.
* include/dbinfo.ch
* include/hbrdddbf.h
* src/rdd/dbf1.c
+ added new RDD switch RDDI_SETHEADER
It allows to define how DBF header is updated in tables which
will be opened later, i.e.:
// maximize performance reducing number of DBF header updating
// header is updated only when table is closed if before new
// record was added
hb_rddInfo( RDDI_SETHEADER, DB_SETHEADER_MINIMAL )
or:
// update header in the same moment as Clipper and xBase++
// and store only last two digit from the year for compatibility
// with old dBase and FoxPro versions
hb_rddInfo( RDDI_SETHEADER, ;
hb_bitOr( DB_SETHEADER_CLIPPER, DB_SETHEADER_YYEAR ) )
// DB_SETHEADER_CLIPPER
By default Harbour uses DB_SETHEADER_APPENDSYNC.
For more information look at comments for DB_SETHEADER_* switches
in dbinfo.ch
+ added new table switch DBI_SETHEADER
It has the same meaning as RDDI_SETHEADER but changes the header
updated mode of already open table by dbInfo() function.

! fixed typo in SetGet expression LValue validation
* include/hbstack.h
* src/vm/estack.c

it returns offset of pSymbol function frame on HVM stack or -1
if function/procedure pointed by pSymbol is not called.
* contrib/hbnetio/readme.txt
* contrib/hbnetio/netiosrv.c
* contrib/hbnetio/hbnetio.hbx
+ added new server side function:
netio_ServedConnection() -> <pConnectionSocket>
It returns connection served by netio_Server() in current thread and
can be used inside executed RPC functions to access <pConnectionSocket>
* include/hbjson.h
* src/rtl/hbjson.c
+ added new C function:
char * hb_jsonEncodeCP( PHB_ITEM pValue, HB_SIZE * pnLen,
HB_BOOL fHuman, PHB_CODEPAGE cdp );
It allows to pass explicitly codepage in which strings inside pValue
are encoded. If cdp parameter is not NULL then it's used to extract
unicode character values from passed strings and this values is used
to encode to encode non ASCII characters as "\uXXXX" where XXXX is
unicode character value. Data serialized in such way is 7bit clean.
If this parameter is NULL then strings are encoded in raw form just
like in hb_jsonEncode().
+ added new C function:
HB_SIZE hb_jsonDecodeCP( const char * szSource, PHB_ITEM pValue,
PHB_CODEPAGE cdp );
It allows to pass explicitly codepage used for strings decoded from
JSON data. If this parameter is NULL then strings are decoded in raw
form and unicode character with code over 255 are converted to '?'
char.
+ added optional 3-rd parameter with codepage ID to PRG functions
hb_jsonEncode() and hb_jsonDecode(). If this parameter is not given
then above functions works like before this modification:
hb_jsonEncode() uses raw string encoding and hb_jsonDecode() uses
current HVM CP to decode characters encoded as \uXXXX.
+ modified PRG function hb_jsonDecode() to return decoded data
instead of length of decoded data when second parameter is not
passed by reference.
* include/harbour.hbx
* src/rtl/dateshb.c

* include/hbset.h
* src/vm/set.c
+ added new C function:
int hb_setUpdateEpoch( int iYear );
if necessary it converts year respecting _SET_EPOCH settings
* src/rtl/dates.c
* use hb_setUpdateEpoch() instead of local code
* src/rdd/dbf1.c
! respect _SET_EPOCH decoding DBF update time from DBF HEADER
(LUpdate() function).
It's not Cl*pper compatible anyhow looks that most of tools
stores only last two digits from the year (just like in the
DBF documentation) and -1900 trick is not used so it helps
to decode correct update date.
* store 'year % 100' instead of 'year - 1900' in DBF header
when DBF table with VFP signature is used (DB_DBF_VFP).
* include/hbapirdd.h
* src/rdd/wacore.c

HB_ULONG ulMilliSec
[INCOMPATIBLE]
* src/rdd/dbdetach.c

! restored original Cl*pper behavior in memo line functions,
test shows that inside MemoEdit() Cl*pper internally uses a little
bit different rules to format text then in memo line functions,
It's Cl*pper bug but hard to fix because any differences to Cl*pper
in this area cause that someone reports them as bug. So I decided
to leave original Cl*pper behavior for compatibility and add new
function which can be used in MemoEdit() and related code.
+ added new memo line function:
hb_MLEval( <cString>, <bCode>, [ <nLineLength>=79 ],
[ <nTabSize>=4 ], [ <lWrap>=.T. ],
[ <nPos> ], [ @<nRow> ], [ @<nCol> ] ) -> <nLines>
it formats texts using rules like in Cl*pper MemoEdit() not Cl*pper
memo lines functions. For each processed line <bCode> is executed
with 2 parameters: <cLine> and <lSoftCR>. It recognizes and accepts
any EOLs just like hb_ATokens( <cText>, .T. ) and strips or converts
soft CRs depending on word wrap mode.
* src/rtl/teditor.prg
* Use hb_MLEval() to format text

* added workaround for bug in some Linux kernels (i.e.
3.13.0-64-generic Ubuntu) in which select() unconditionally
accepts terminal device for reading if c_cc[ VMIN ] = 0
It's very serious problem, i.e. in GTTRM no input is possible
in such kernels without this workaround.
* src/rtl/dirscan.prg
* modified hb_DirScan() and hb_DirRemoveAll() to work with Harbour
File IO API (hb_vf*() functions)
+ added new PRG function:
hb_FileDelete( <cFileMask> [, <cAttr> ] ) -> <lResult>
this function removes files which match given <cFileMask>
(it may contain path) and returns .T. if at least one file
was deleted. Optional <cAttr> parameter can be used to include
system ("S") and hidden ("H") files. If <cAttr> contains "R"
letter then before deleting READONLY attribute is removed from
files (it's necessary to remove files with READONLY attribute
in systems like DOS, MS-Windows or OS2). This function uses
Harbour File IO API (hb_vf*() functions)
* remove READONLY attribute from files in hb_DirRemoveAll()
* include/harbour.hbx
+ added hb_DirRemoveAll() and hb_FileDelete()
* contrib/hbct/files.c

* minor modification in variable name
* src/rtl/filebuf.c
* src/rtl/fscopy.c
* src/rtl/fslink.c
* src/rtl/vfile.c
* cleaned FError() setting. It should not be changed by C file IO
functions because they can be activated from RDD code so accessing
work area field could change the FError() result, i.e. this code
does not work when FError() is changed by C level IO operations:
AnyFunc( FSeek( hFile, 0, FS_END ), field->MEMOVAL, FError() )
Even simple field access may cause file IO operations in RDD code
when relations are set because records in child area are repositioned
only when necessary (when user tries to make some operations on this
area). In the past RDD code was full of constructions like:
uiSaveError = hb_fsFError();
// make some IO operations
hb_fsSetFerror( uiSaveError );
to eliminate such overhead I separated PRG level FError() from
C level IOError(). Please keep it.
* ChangeLog.txt

+ added new C function for OS2 builds: hb_fsOS2QueryPathInfo()
Unlike DosQueryPathInfo() it uses dir entries so it does not need to
open the file what can create file sharing violation problem.
+ added new C function for OS2 builds: hb_isWSeB()
It returns true if OS2 version supports long file API
(IBM OS/2 Warp Server for e-Business)
+ added new C functions for OS2 builds:
hb_fsOS2DosOpenL(), hb_fsOS2DosSetFileLocksL(),
hb_fsOS2DosSetFilePtrL(), hb_fsOS2DosSetFileSizeL()
These are dynamically initialized wrappers to OS2 long file API
functions if such functions exists in given OS2 version.
* src/common/hbfsapi.c
* use hb_fsQueryPathInfo() in OS2 builds of hb_fsNameExists(),
hb_fsFileExists() and hb_fsDirExists()

after switching to 64bit reference counters it should not
be longer necessary because allocated that has 64bit alignment
* include/hbapifs.h
* src/rtl/filebuf.c
* added new C function hb_fileLoadData() - it can be used to load data
from already opened regular files and streams

! fixed typo in ChangeLog entry. I used hb_socketNew() instead of
hb_socketSetFilter()
* include/hbapifs.h
* src/rtl/filebuf.c
+ added helper C function:
HB_SIZE hb_fileResult( HB_SIZE nSize );
It converts ( HB_SIZE ) FS_ERROR to 0 so it can be used to wrap
hb_fileRead()/hb_fileWrite() to force previous results.
* src/rdd/dbffpt/dbffpt1.c
* reduced variable scope
* src/rtl/copyfile.c
! fixed typo in last commit - thanks to Viktor.
* include/fileio.ch
+ added few HB_VF_* macros for hb_vfConfig() settings
* contrib/hbcomio/comio.c
* contrib/hbtcpio/tcpio.c
+ implemented HB_VF_TIMEOUT, HB_VF_PORT, HB_VF_SHUTDOWN, HB_VF_RDHANDLE
and HB_VF_WRHANDLE hb_vfConfig() settings, i.e. now
hb_vfConfig( pFile, HB_VF_TIMEOUT, <nTimeOut> ) -> <nTimeOut>
can be used to change default timeout in TCP and COM Harbour File IO
handles.
* include/hbsocket.h
* src/rtl/hbsockhb.c
+ added socket filters to standard socket API.
At C level hb_sockex*() function with PHB_SOCKEX handler can be
used to operate on socket filters. At PRG level standard hb_socket*()
functions can be used.
The following things has been changed in PRG hb_socket*() functions:
hb_socketErorrString() can accept <pSocket> as 1-st or 2-nd parameter
and redirect call to socket filter errorStr() method.
hb_socketClose() executes automatically shutdown() for connected
sockets - it is important in windows only where without explicit
call to shutdown() before close transmitted data can be lost.
hb_socketSend() and hb_socketRecv() can be redirected to filter
streams if filter set such redirection. If filter does not redirect
them then they operate on raw sockets. If hb_socketSend() is
redirected then sent data is flushed automatically.
The following new PRG functions has been added:
Add/replace socket filter:
hb_socketSetFilter( <pSocket>, [<cFilterName>], [<hParams>] )
-> <pSocket> | NIL
<cFilterName> is filter name, It's possible to set many filters
in single hb_socketSetFilter() call separating filter names
with "|" character, i.e.:
pSock := hb_socketSetFilter( pSock, "ZSOCK|BFSOCK", hParams )
<hParams> is hash array with initialization parameters used by
given socket filter. The core implementation recognize the
following settings:
"readahead" - numeric value with size of read ahead buffer
"flush" - numeric value with auto flush parameter (for more
information look at hb_socketAutoFlush() below)
"redir" - logical value which can be use to enable/disable
hb_socketSend() and hb_socketRecv() redirection
to filter stream.
Return filter name used by socket:
hb_socketGetFilter( <pSocket> ) -> <cFilterName>
Read from socket stream:
hb_socketRead( <pSocket>, @<cData>, [<nLen> = Len( cData )],
[<nTimeout> = FOREVER] ) -> <nRead>
this function is similar to hb_socketRecv() but is always
redirected to socket stream filters.
Write to socket stream:
hb_socketWrite( <pSocket>, <cData>, [<nLen> = Len( cData )],
[<nTimeout> = FOREVER] ) -> <nWritten>
this function is similar to hb_socketSend() but it is always
redirected to socket stream filters. Written data is not flushed
by default and it should be flushed explicitly by hb_socketFlush().
Automatic flushing can be enabled by hb_socketAutoFlush() function.
Flush data written to socket:
hb_socketFlush( <pSocket>, [<nTimeout> = FOREVER], [<lSync>] )
-> <nNotFlushed>
<lSync> parameter is logical value which can be used to force
special synchronization method in some filters. Usually users
do not have to use it in normal code.
Enable/disable automatic flushing of written data.
hb_socketAutoFlush( <pSocket>, [ <nTimeout> ] ) -> <nTimeout>
<nTimeout> is timeout for automatic flush operation on written
data in milliseconds. <nTimeout> = -1 means wait forever and
<nTimeout> = 0 disables auto flush.
automatic flushing can help in adopting existing code anyhow it
may strongly reduce the performance in some filters, i.e.
compression filters like ZSOCK have to add special data to the
stream after each flush operation so it's suggested to call
flush explicitly when we want to force delivering written data
to the peer.
* include/hbznet.h
* src/rtl/hbznet.c
+ added ZNET socket filter - compressed and encrypted streams are
compatible with hb_znet*() streams. The old hb_znet*() interface
is obsolete for pure socket communication and if not used as
hb_inet*() filter then should be replaced by hb_sockex*() in
user programs.
ZNET socket filter can be created by new PRG functions:
hb_socketNewZNet( <pSocket>, [<cPass>], [<nCompressionLevel>], ;
[<nStrategy>] ) -> <pSocket> | NIL
or by standard socket API with "ZNET" as filter name.
ZNET filter recognize the following settings in initialization
hash array:
"key" or "pass" - string with encryption password
"zlib" - numeric compression level (HB_ZLIB_COMPRESSION_*)
"zs" - numeric ZLIB compression strategy (HB_ZLIB_STRATEGY_*)
ZNET filter always disables any other filters and operates on raw
socket.
Please remember that it's optional module. If programmer does not
use hb_socketNewZNet() explicitly and prefers using hb_socketNew()
then he should force linking this module by REQUEST hb_socketNewZNet
+ added fSync parameter to hb_znetFlush()
[INCOMPATIBLE]
* src/rtl/hbinet.c
* call flush filter function before socket is closed
* src/rtl/Makefile
+ src/rtl/hbzsock.c
+ added ZSOCK socket filter - ZLIB and GZIP compression for socket
streams.
ZSOCK socket filter can be created by new PRG functions:
hb_socketNewZSock( <pSocket>, [<hParams>] ) -> <pSocket> | NIL
or by standard socket API with "ZSOCK" as filter name.
Programmers using hb_socketNew() can force linking this module by
REQUEST hb_socketNewZSock
ZSOCK filter can be used with other filters.
ZSOCK filter recognize the following settings in initialization
hash array:
"zlib" - numeric compression level (HB_ZLIB_COMPRESSION_*)
"zs" - numeric ZLIB compression strategy (HB_ZLIB_STRATEGY_*)
"zin" - logical value which allow to enable/disable ZLIB
decompression on input stream (default)
"gzin" - logical value which allow to enable/disable GZIP
decompression on input stream - it's possible to
enable both ZLIB and GZIP decompression together
so both streams can be decompress
"zout" - logical value which allow to enable/disable ZLIB
compression on output stream (default)
"gzout" - logical value which allow to enable/disable GZIP
compression on output stream - if both "zout" and
"gzout" are enabled GZIP compression is used.
* src/rtl/Makefile
+ src/rtl/hbbfsock.c
+ added BFSOCK socket filter - BlowFish input and output stream
encryption in CTR mode.
BFSOCK socket filter can be created by new PRG functions:
hb_socketNewBFSock( <pSocket>, [<hParams>] ) -> <pSocket> | NIL
or by standard socket API with "BFSOCK" as filter name.
Programmers using hb_socketNew() can force linking this module by
REQUEST hb_socketNewBFSock
BFSOCK filter can be used with other filters, i.e. with ZSOCK.
Please only remember that good encryption algorithms have to
generate data which cannot be compressed so using "BFSOCK|ZSOCK"
only wastes resources and correct filter order is "ZSOCK|BFSOCK".
BFSOCK filter recognize the following settings in initialization
hash array:
"key" or "pass" - string with encryption password
"iv" - string with initialization vector for CTR mode

* contrib/hbssl/hbssl.hbx
* contrib/hbssl/ssl.c
* contrib/hbssl/ssl_inet.c
+ contrib/hbssl/ssl_sock.c
+ added SSL socket filter
SSL socket filter can be created by new PRG functions:
hb_socketNewSSL_connect( <pSocket>, <pSSL> [, <nTimeout> ] )
-> <pSocketSSL> | NIL
hb_socketNewSSL_accept( <pSocket>, <pSSL> [, <nTimeout> ] )
-> <pSocketSSL> | NIL
or by standard socket API with "SSL" as filter name.
Programmers using hb_socketNew() can force linking this module by
REQUEST hb_socketNewSSL_connect
or
REQUEST hb_socketNewSSL_accept
SSL filter always disables any other filters and operates on raw
socket.
SSL filter recognize the following settings in initialization hash
array:
"ctx" or "key" - pointer SSL item <pSSL>
"timeout" - timeout (numeric)
"client" - logical value indicating client mode (SSL_connect())
"server" - logical value indicating server mode (SSL_accept())
* contrib/hbssl/tests/inetssl.prg
! cleaned typo in local function name
* contrib/hbnetio/netiocli.c
* contrib/hbnetio/netiosrv.c
* use new Harbour extended socket API (hb_sockex*()) instead of
raw sockets and hb_znet*()
* contrib/hbtcpio/tcpio.c
* use new Harbour extended socket API (hb_sockex*()) instead of
raw sockets
+ implemented hb_fileFlush()
* contrib/hbtcpio/tcpio.c
* contrib/hbtcpio/hbtcpio.hbx
+ added new PRG function
hb_vfFromSocket( <pSocket> ) -> <pFile>
It converts socket created by socket open into TCPIP virtual file
which works just like files created by hb_vfOpen( "tcp:...", ... )
* include/hbapifs.h
* src/rtl/filesys.c
+ added new C function
HB_SIZE hb_fsPipeWrite( HB_FHANDLE hPipe, const void * buffer,
HB_SIZE nSize, HB_MAXINT nTimeOut );
+ implemented hb_fsPipeUnblock() in OS2 builds
+ set IO error in hb_fsPipeCreate(), hb_fsIsPipeOrSock() and
hb_fsPipeUnblock()
* return ( HB_SIZE ) -1 from hb_fsPipeRead() if end of stream is
reached or read error appears on non empty buffer. This modification
also change the behavior of PRG hb_PRead() function so now result -1
can be used to detect end of stream.
* src/rtl/philes.c
* include/harbour.hbx

hb_PWrite( <nPipeHandle>, <cBuffer>, [<nBytes>], [<nTimeOut>] )
-> <nBytesWritten>
% removed unnecessary assignment
* include/hbapiitm.h
+ added HVM internal macro hb_itemRawSwap()
* src/vm/asort.c
