* 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.
* src/rtl/itemseri.c
* minor update in comments
* contrib/hbct/ctwin.c
* src/rtl/hbgtcore.c
! fixed GTCTW window handle save/restore on debugger activation
I broke in 107b36e847
Thanks to Rolf for the info and patch.
* contrib/hbziparc/ziparc.prg
* synced with Viktor's branch.
This code should contain Rolf fixes. Please test.
* src/rtl/gtwin/gtwin.c
+ added support for disabling [x] button of console window in older
MS-Windows versions which do not have GetConsoleWindow() function,
i.e. Win9x/ME
* 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
* include/hbapicls.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/hbtip/mail.prg
! fixed missing 1-st adress in CC and BCC parameters - many

* contrib/hbtip/sendmail.prg
! typo in comment - thanks to Heinz V Bergen too
* src/rtl/gtwvt/gtwvt.c
* some minor modification to sync code with Vitkor's branch

* src/vm/itemapi.c
* small optimization in string comparison
* src/debug/dbgentry.c
* src/debug/debugger.prg

* use one function to divide text per lines with the same rules
as used in Cl*pper and Harbour PP.
! fixed input line size in SET edit window
! fixed validation in some input boxes
* process only 1-st parameter in some commands just like Cl*pper does
+ added support for FILE OPEN <name> command
! fixed CALLSTACK ON | OFF command
! fixed NUM command
+ added support for VIEW <fileName> command
+ added support for LOCATE GOTOLINE <line> command
+ added support for LOCATE FIND <text> command
+ added support for RUN SPEED <num> command
+ added support for LIST WP|TP command
+ added support for BP <funcName> command
+ added support for DELETE ALL [TP|WP] and DELETE WP|TP <number>
commands
% few optimizations and some other minor fixes
+ contrib/hbcomio/hbcomio.hbx
+ added missing hbx file
* package/harbour.spec
! fixed to not corrupt root filesystem during package build process.
It was necessary to set HB_INSTALL_CONTRIB with package install prefix.
(undocumented functionality)
TODO: add single variable which can be used in such case for all
HB_INSTALL_* variables.
+ added support for HBMK2 .hbc files for contrib libraries
* src/debug/dbgbrwsr.prg
! fixed to not display last column out of browser area
* src/debug/dbghelp.prg
* src/debug/dbgmenu.prg
* src/debug/debugger.prg
* use strings to to locate help topics instead of hardcoded numeric
offsets
! added support for topic specification in "HELP" command - Cl*pper
compatibility
! allow to use FILE DOS (and F D shortcut) to activate OS Shell - Cl*pper
compatibility
* src/debug/dbgentry.c
! removed recent pseudo fix with memset() missing the last byte of
allocated memory area since e59993bdb1.
The original code was correct. In Harbour trailing 0 in all strings
is set inside functions creating string items.
* package/harbour.spec
+ added MXML library
* package/mpkg_rpm.sh
* respect HB_WITH_*=no and HB_WITH_*=local envvars
* src/debug/*
+ src/debug/en.txt
* sync with 4d61fc5a25/src/debug
* use DBS_* constants
! fixed to allow editing of CODEBLOCK types in hash/array/object elements
as it was allowed in single variables
! fixed to detect all workareas not just the first arbitrary 512
! fixed memset() missing the last byte of allocated memory area
since e59993bdb1
+ reworked help to store content in a text file out of the source code.
It reduces binary size, makes translation possible, editing easier,
source code leaner and easy to publish online.
! deleted help section explaining cld.exe
* formatting, cleanups, optimization, translatability
* contrib/hbnetio/hbnetio.hbx
* contrib/hbnetio/netiocli.c
* contrib/hbnetio/readme.txt
+ added new client side function:
netio_TimeOut( <pConnection> [, <nTimeOut>] ) -> [<nTimeOut>]
Get/Set client side timeout for messages
+ inherit timeout used in socket connection and use it for farther
message processing.
Warning: incompatible, for slow connections or time consuming RPC
functions people should set timeout using netio_TimeOut()
function. In previous version timeout was set to -1 what
means wait forever without any time limits or until
connection is broken.

allocateing new block in each hb_xrealloc() call
! protect realloc() in HB_FM_STATISTIC by mutex, it fixes issue #77.
* src/rtl/hbproces.c
% unlock HVM waiting for process in OS2 builds
! build array of argument passed to process in hb_processRun() in
parent process not forked one. It fixes possible deadlock in forked
process because memory is allocated to create arguments array and
in MT program memory managers may use mutexes internally which can
be cloned to forked process in locked state.
It fixes seldom and random HBMK2 freezing during compilation
with -jobs=<n> parameter.
* utils/hbmk2/hbmk2.prg

! fixed hardcoded limit for 512 workareas in WA inspector
! fixed initial WA positioning in WA inspector
* resized WA inspector window
* many other minor fixes and improvements
* src/common/hbfopen.c
* use _wfopen() instead of fopen() in MS-Windows UNICODE builds of
hb_fopen(). It means that now hb_fopen() makes exactly the same file
name conversions as hb_fs*() Harbour RTL functions, i.e. hb_fsOpen()
* contrib/hbmxml/core.c
! fixed unnecessary conversions to UTF8 used for file names passed
to hb_fopen()
* contrib/hbmzip/3rd/minizip/ioapi.c
* contrib/hbmzip/3rd/minizip/minizip.dif
! fixed wrongly used hb_fopen() instead of fopen() what caused double
file name conversions when 32-bit stdio API was used.
* contrib/hbwin/olecore.c

+ aded new function OleDefaultArg()
% minor simplification
* src/rtl/itemseri.c

% 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

! fixed bad typo inside hb_fileIsLocalName() - result was reverted.
Many thanks to Juan Gálvez for locating the problem.
* src/debug/dbgbrwsr.prg

* 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.
* contrib/gtqtc/gtqtc.h
* contrib/gtqtc/gtqtc1.cpp
* overload inputMethodEvent() in console object and insert
commitString() data into GT keyboard input queue.
It's necessary for Android working with SoftwareInputPanel
and it fixes problem with eaten standard characters.
QT documentation says that QInputMethodEvent are generated
only when Qt::WA_InputMethodEnabled attribute is set but
tests shows that it's not true and these events are generated
instead of keyPress/keyRelease ones for simple text input.
CTRL modifier, ESC, INS, HOME, END, PGUP, PGDN and Fn keys
still does not work with GTQTC in Android builds.
* src/rtl/tbrowse.prg

* contrib/gtwvg/gtwvg.hbx
* regenerated with new function
* 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.

; Most of above modifications were critical for stability of MT programs.
They should allow to activate GC in any place.
* contrib/hbpgsql/rddcopy.c
! fixed typos in my recent modification and potential memory corruption
and/or wrong output due to ugly hack for last field terminator in old
code. Thanks to Aleksander Czajczynski for reporting the problem.
* src/vm/garbage.c
! added protection for activating GC from thread with unlocked HVM stack
when other thread is already executing GC passes. Such situation does
not happen in core code and the protections is only just in case.
* src/vm/hvm.c
! do not release HVM thread STOP signal when GC mark pass is activated.
It was very serious bug which could cause memory corruption when
thread unlocked HVM stack what allow to start GC mark pass by other
thread and then locked HVM and begin to change complex variables
still scanned by the GC thread. This problem have existed from the
beginning when I committed initial version of Harbour MT support.
I do not remember why I added code to remove the STOP signal - probably
I was experimenting with some new things working on Harbour MT code
and I forgot to deactivate it.
NOTE: 3-rd party developers who use GC collectible pointer items
must not activate any PRG code execution inside their mark
functions.
* include/Makefile
+ include/hbiousr.ch
* src/rtl/Makefile
+ src/rtl/iousr.c
+ added module for writting Harbour FILE IO redirectors at PRG level

It's IOTCP and gives exactly the same functionality as TCP redirector
in contrib which is written in C.
