* include/hbapi.h
* src/vm/garbage.c
+ 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.
