* minor optimization
* src/common/hbprintf.c
* pacified warning
* src/rtl/filesys.c
! return -1 instead of from hb_fsPipeIsData() when poll() detects
error or end of stream - 0 should indicate timeout only.
* src/rtl/hbcom.c
! fixed bad typo which blocked hb_comSend() in *nixes
using select() instead of poll()
* src/rtl/filesys.c

* pacified few warnings - thanks to Viktor
* contrib/sddfb/core.c
! fixed code which extracted float number from uninitialized memory.
On some systems it could even cause GPF or other (ie. FPE) exception.
* src/rtl/hbproces.c
! fixed infinite loop due to ignored POLLHUP errors reported by poll()
! fixed stupid typo
* src/rtl/hbproces.c
* src/rtl/hbsocket.c
* src/rtl/filesys.c
* src/rtl/hbcom.c
* emulate read access when poll() used instead of select() reports
POLLHUP - this poll() behavior is neither consistent within a
single implementation, nor between different versions of the same
implementation, and certainly not across platforms
% optimize read/write access using extended (in comparison to select())
information reported by poll()
; TODO: emulate select() behavior for high priority data.
* src/rtl/gttone.c
! use asm {} directive only in CLANG BCC builds - asm {} needs TASM
so using it breaks Harbour compilation with free BorlandC command
line tools which do not contain TASM.
* src/rtl/hbsocket.c
* src/rtl/hbproces.c
* src/rtl/filesys.c
* src/rtl/hbcom.c
! use poll() instead of select() in POSIX.1-2001 compliant *nix builds
It fixes the problem with file handles >= 1024
Please make tests in different *nix builds. It affects sockets, pipes
and serial ports.
* src/rtl/direct.c
! removed set of MS-Windows attributes passed unconditionally to
hb_fsFind*() functions in Directory() PRG function.
It fixes "L" attribute passed in 2-d parameter of Directory()
function in *nix builds. When "L" is given in attribute list
then Directory() do not follow links.
* src/common/strwild.c
* removed FNM_PERIOD from fnmatch() parameters in *nix builds
* src/common/hbffind.c
* in * nix builds set hidden attribute for file and directory
names starting with "." except "." and ".." which are reported
as is for Cl*pper and Harbour multiplatform compatibility.
* src/rtl/gttone.c
* applied patch from Andi Jahja for new BCC versions - many thanks
* src/rtl/strrepl.c
% added optimization code for strings longer then 1024 bytes
For very long strings it can improve replace performance 20 or
even more times.

! HB_ISPRINTER(), ISPRINTER() fix to open the port name with CREATE
flag (= CREATE_ALWAYS on Windows). It may fix port detection in
certain situations. Tested on Windows 7 x86 and x64, whereas it
will now return .T. if the port is associated with a queue,
and .F. if it isn't. It seems to cause no harm on OS X. Please
test it on other systems and other LPT scenarios (f.e. with real
hardware device attached).

* ChangeLog.txt
; hide e-mail addresses
* src/rtl/gttrm/gttrm.c
+ added support for CYGWIN ssh terminal
(i.e. ssh.exe included in github for MS-Windows)
! fixed support for terminals which always scrolls when the most
upper/right character is written.
In current version GTTRM simply ignores this character cell.
On such terminals it can be shown by writing the last character
one cell before then sending escape sequences to move cursor back,
insert one space and finally restoring overwritten character
cell value. Anyhow it increases number of used escape sequences
so I decided to not implement it yet.
* src/rtl/hbgtcore.c
! fill whole box area in DispBpx() when 0 length string or string with
Chr( 0 ) at the beginning is used as box frame - Cl*pper compatible
behavior
* include/hbapifs.h
* src/rtl/filesys.c
+ added new C function:
HB_FOFFSET hb_fsGetSize( HB_FHANDLE hFileHandle );
! fixed SetFilePointer() error detecting - it was broken
and we returned wrong results for offset 0xFFFFFFFF
* src/rtl/filebuf.c
* use hb_fsGetSize()
* src/rtl/hbsocket.c
* enabled new socket functions in MSC 18.0 (before was MSC 19.0)
If someone uses this compiler and this modification created problem
then please let me now.
* src/rtl/gtxwc/gtxwc.c
! fixed buffer overflow in HB_GTI_FONTATTRIBUTE used after
after console window initialization
! set XLib mutex when font size is changed by HB_GTI_FONTSIZE
after console window initialization (for MT programs using
more then one GTXWC console simultaneously).
! allow HB_GTI_FONTSIZE to change font created by HB_GTI_FONTSEL
using before console window is created
% do not create new console window pixmap if old one has the
same dimensions
* include/hbapifs.h
* 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().
* src/rtl/filesys.c
* src/rtl/hbcom.c
* src/rtl/hbproces.c
* use hb_fsOS2DosOpen() instead of DosOpen()
* src/vm/cmdarg.c
* set the initial size of file handle table to 256 in OS2 OpenWatcom
builds if user does not set it explicitly by //F:<n> switch
* config/global.mk
- removed set HARBOUR=F:100 - it's not necessary with automatic FHT
resizing
; Please test it in real OS2 environment
* contrib/gtqtc/gtqtc.h
* contrib/gtqtc/gtqtc1.cpp
* renamed few variables to avoid -Wshadow warnings
* contrib/hbfimage/fi_wrp.c
* removed unnecessary ;
* contrib/hbodbc/odbc.c
! replaced '\0' with NULL in pointer initialization
* src/3rd/jpeg/Makefile
% added missing HAVE_UNSIGNED_CHAR build macro. Without it LIBJPEG
uses SHORT to hold unsigned 8 bit integers what increases memory
usage and reduces the speed.
* src/pp/hbpp.c
* minor modification to keep string constant C90 comnpatible
* src/rtl/filesys.c
* simplified DOS to POSIX file attribute translation
+ respect hidden and system file attribute in DOS builds of hb_fsOpenEx()
* src/vm/fm.c
! added yet another missing HB_STACK_TLS_PRELOAD
* *
% remove brandings and homepage from copyright header. Pass 2 - semi-auto.
* project homepage and name is described in README, amongst others
; this should make the diff between 3.4 and 3.2 easier to manage
* *
% remove brandings and homepage [1] from copyright header. Pass 1 - using script.
[1] nobody has access to it anymore AFAIK - and it's also just
a redirect since long
! update url in copyright header
; this should make the diff between 3.4 and 3.2 easier to manage
* config/global.mk
* set HARBOUR=F:100 during build process in OS2 builds - it increases
maximum number of open handles per process from 20 to 100 so it should
be possible to use -j<n> switch during Harbour compilation - please
test, i.e.:
os2-make -j3
* contrib/xhb/hbcompat.ch
! fixed pp rules for Str(,,, <lStrip> ) translation
* include/hbapifs.h
* src/rtl/filesys.c
+ added new C function:
HB_FHANDLE hb_fsOpenEx( const char * pszFileName, HB_FATTR nAttr,
HB_USHORT uiFlags );
* 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
* use HB_MEM_STATISTICS instead of HB_MEM_USEDMAX to check if memory
statistic module is enabled
* contrib/hbtip/encurlc.c
! fixed C&P typos in tip_URLEncode() and tip_URLDecode() in may
previous commit
* src/pp/ppcore.c
* pacified warning
* src/common/hbver.c
* src/rtl/hbsocket.c
* updated for Digital Mars C compilation
* include/hbsocket.h
* src/rtl/hbsockhb.c
+ added new C function:
HB_BOOL hb_sockexItemReplace( PHB_ITEM pItem, PHB_SOCKEX pSock );
* contrib/hbssl/ssl_sock.c
+ replace passed socket structure to hb_socketNewSSL_connect() and
hb_socketNewSSL_accept() with new one using SSL filter if it was
passed by reference, current syntax is:
hb_socketNewSSL_connect( [@]<pSocket>, <pSSL> [, <nTimeout> ] )
-> <pSocketSSL>
hb_socketNewSSL_accept( [@]<pSocket>, <pSSL> [, <nTimeout> ] )
-> <pSocketSSL>
* contrib/hbssl/hbssl.hbm
* contrib/hbssl/hbssl.hbx
+ contrib/hbssl/ssl_hbcon.prg
+ added new PRG functions which can be used for fast initialization of
SSL connection:
hb_SSL_new() -> <pSSL>
hb_SSL_connect_inet( <pSocket>, [ <nTimeOut> ], [ @<cInfo> ] )
-> <lConnected>
hb_SSL_connect_socket( <pSocket>, [ <nTimeOut> ], [ @<cInfo> ] )
-> <lConnected>
They do not need any addiitonal initialization code and can be called
as first and the only SSL functions in user code.
* contrib/hbtip/mail.prg
! fixed bug reported by Lorenzo - thanks
* use hb_MemoWrit() in :detachFile() to honor Harbour File IO API
* cleanup
* src/common/hbffind.c
* src/rtl/gtos2/gtos2.c
* src/rtl/hbproces.c
* cleaned DosAllocMem() flags
* src/common/hbfsapi.c
* src/rtl/hbproces.c
* pacified OS2 GCC warnings
* config/global.mk
* show information about HB_MT build parameter if set by user
* contrib/hbtip/encurlc.c
! fixed url decoding - thanks to Lorenzo for reporting the problem
* small simplification of url encoding code
* src/rtl/hbproces.c
! use DosAllocMem() instead of hb_xgrab() to allocate memory for
DosExecPgm() parameters - it should fix the problem with random
build crashes when pipes are used for redirection of child
process standard IO handles - please test in real OS2 environment.
* src/rtl/spfiles.c
! typo in HB_TR_DEBUG message
* src/rtl/hbproces.c
- removed unnecessary call to hb_fsSetIOError()
% variable localization
! fixed wrongly located hb_vmLock() - it was not called if
hb_fsProcessOpen() failed.
* include/hbapigt.h
* src/rtl/gttrm/gttrm.c
* modified GTTRM to generate HB_K_CLOSE if input stream is closed and
then HB_K_TERMINATE on next inkey calls.
* src/rtl/hbznet.c
* src/rtl/hbzsock.c
! cleanup
* include/hbrdddel.h
* include/hbrddsdf.h
* src/rdd/delim1.c
* src/rdd/sdf1.c
+ added support for any standard EOL combination to DELIM and SDF RDDs,
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
+ src/3rd/hbdossrl/Makefile
+ src/3rd/hbdossrl/serial.c
+ src/3rd/hbdossrl/serial.h
+ src/3rd/hbdossrl/README
+ added DOS Serial Library - it's much cleaner and simpler then COMLib
we used so far in DOS builds. It also supports hardware and software
flow control. Many thanks for Karl Stenerud for his wonderful job.
* src/rtl/hbcom.c
+ added support for DOS Serial Library used as low level backend in
Harbour DOS builds.
* config/dos/djgpp.mk
* config/dos/watcom.mk
* config/dyn.mk
* config/lib.mk
* src/3rd/Makefile
* src/Makefile
* utils/hbmk2/hbmk2.hbp
* utils/hbmk2/hbmk2.prg
* use DOS Serial Library (hbdossrl) instead of COMLib (hbpmcom)
* 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.
* src/rtl/filebuf.c
! added missing redirection for Configure() method.
* src/rtl/hbproces.c
! fixed sysconf() emulation for OpenWatcom 1.9 and earlier to work with
_SC_PAGESIZE
* src/rdd/dbf1.c
* update DBF header only after modification in COMMIT and CLOSE methods.
It's Cl*pper and xBase++ compatible behavior anyhow it also means that
number of records in DBF header is not modified just after APPEND
so it cannot be used to synchronization in concurrent file access.
* src/rtl/hbproces.c
! safe and restore hb_fsError() when unused pipe handles are closed
in hb_fsProcessOpen()
! add extension (.com or .exe) in hb_fsProcessOpen()/hb_fsProcessRun()
when executed command is given with PATH part and without extension.
It's documented that DosExecPgm() needs full filename in such case.
It fixes problem with contrib/make.hb which calls hbmk2 with directory
part but without extension.
! enabled pipes instead of temporary files for stdio redirection in OS2
builds of hb_fsProcessRun() - now it should work correctly.
* src/rtl/hbprocfn.c
+ update FError() in hb_Proces*() functions
* 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
+ added two new PRG functions:
hb_SecToT( <nSeconds> ) -> <tTime>
hb_MSecToT( <nMilliseconds> ) -> <tTime>
* 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).
* src/rtl/filebuf.c
! fixed file handle sharing in POSIX systems when writeonly mode is used
! fixed accessing files in writeonly mode in POSIX systems which use
fcntl() locks for DENY_* flag emulation.
! added for POSIX systems protection against potential race condition in
MT programs and file open and close operations. Now the whole low level
open and close operations are covered by mutex. It means that they are
fully serialized so in case of remote file access (i.e. NFS or SMBFS)
it may reduce the performance in applications which simultaneously open
and closes many different files in different threads but its necessary.
For local file access it should not create noticeable scalability
problems. In my Linux box Harbour can open and close in MT mode more
then 250000 files per second.
% use different mutexes for file open/close and file lock operations to
not reduce the lock performance by potentially slow open() operation
in POSIX systems.
; NOTE: please remember that DENY_* flag emulation in POSIX systems
emulates only shared and exclusive modes so if any of
FO_DENYREAD, FO_DENYWRITE or FO_EXCLUSIVE flag is used then
it effectively works like FO_EXCLUSIVE in POSIX system and
is not mandatory for other processes so it blocks only
other Harbour applications which use Harbour virtual handles
(RDD code, hb_vf*() functions)
* src/rtl/filesys.c
* do not convert exclusive lock to shared one when file is open in
readonly mode on POSIX system using flock() for DENY_* flag emulation.
Now HB_USE_BSDLOCKS is enabled only for Linux and it's documented that
this implementation allow to use shared and exclusive locks regardless of
file open mode.
% do not create file name copy in hb_fsExtOpen() when passed parameters
does not force file name modification
* src/rtl/gtwin/gtwin.c
* added workaround for compilers which do not have MOUSE_HWHEELED macro
(thanks to Alexey)
* src/rtl/gtwvt/gtwvt.c
* do not use LR_DEFAULTSIZE in WinCE builds (synced with Viktor's branch)
* tests/gtkeys.prg
* casing
