+ added hb_gcDummyClear() function
* include/hbapirdd.h
* include/hbusrrdd.ch
+ added DBTF_CPYCTR constant value - when set in dbTransInfo.uiFlags
then after record transfer field counters should to be copied from
source to destination area
* include/hbapirdd.h
* src/rdd/wafunc.c
+ added new C functions hb_dbTransInfoPut() and hb_dbTransInfoGet()
which allow to store and retrieve pointer to DBTRANSINFO structure
into/from HB_ITEM with strict type verification.
* src/rdd/wafunc.c
* pass pointer to DBTRANSINFO structure as argument of DBI_TRANSREC
action. It allows RDD serving destination area to decide which
fields and how should be transferred updating uiFlags, uiItemCount
and lpTransItems members of DBTRANSINFO.
If RDD removes all fields from DBTRANSINFO structure (uiItemCount==0)
or does not return HB_SUCCESS for DBI_TRANSREC action (default WA
implementation returns HB_SUCCESS so it's not necessary to overload
it if RDD does not make any additional operations) then record
transfer is interrupted.
* copy field counters only when destination area asked about it setting
DBTF_CPYCTR in dbTransInfo.uiFlags in DBI_TRANSREC action.
* src/rdd/dbf1.c
* do not copy automatically updated fields when destination area
is not empty
* set DBTF_CPYCTR to indicate that counters should be copied from
source to destination area when original value of automatically
updated fields are transferred
; Now DBF* RDDs in Harbour respects the following rules for record
transfer operations (COPY TO / APPEND FROM) with automatically
updated fields:
- COPY TO transfers original values to destination table and
finally copy counters from the source table to destination one
so autoincrement fields in both tables after next append will be
initialized with the same values regardless of number of copied
records - even if only single record is copied then counters in
destination table will inherit next values for new record from
the source table. Also values of RowVer and ModTime fields are
copied from source to destination table and not updated during
transfer operation.
- APPEND FROM works like COPY TO (original field values and then
counters are copied to destination table) if the source table
supports counters and destination table is empty and FLocked()
or opened in exclusive mode.
If source table does not support counters for given fields, i.e.
it is processed by transfer RDD like DELIM or SDF (RDT_TRANSFER)
or destination table is not empty or opened in shared mode and
FLock is not set when APPEND FROM is executed then automatically
updated fields (counters, RowVer, ModTime) are not copied and
initialized with new values like for each new record added to
destination table.

% 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.

* 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.

* 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.
* 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.
