* harbour/include/hbrdddbf.h
* modified DB_DBFLOCK_HB64 locking scheme
- extended RLOCK/FLOCK area from 2^31-2 to 2^32-2
it effectively changes maximum number of records in this
locking scheme to 4'294'967'294
- use COMIX like hyper locking mode
it should increase performance
Warning: INCOMPATIBLE!
all applications using DB_DBFLOCK_HB64 locking mode should
be updated - it is not safe to concurrently access the
same files using programs compiled with older Harbour
versions and current one.
* renamed the following DB_DBFLOCK_* macros:
DB_DBFLOCK_CLIP to DB_DBFLOCK_CLIPPER
DB_DBFLOCK_CL53 to DB_DBFLOCK_COMIX
DB_DBFLOCK_CL53EXT to DB_DBFLOCK_HB32
* added new locking scheme: DB_DBFLOCK_CLIPPER2
This locking scheme is designed to replicate _real_ locking scheme
used by Cl*pper applications linked with NTXLOCK2.OBJ
It's different then the documented one.
; Now Harbour supports the following locking schemes:
DB_DBFLOCK_CLIPPER 1 default Clipper locking scheme
DB_DBFLOCK_COMIX 2 COMIX and CL53 DBFCDX hyper locking scheme
DB_DBFLOCK_VFP 3 [V]FP, CL52 DBFCDX, SIx3 SIXCDX, CDXLOCK.OBJ
DB_DBFLOCK_HB32 4 Harbour hyper locking scheme for 32bit file API
DB_DBFLOCK_HB64 5 Harbour hyper locking scheme for 64bit file API
DB_DBFLOCK_CLIPPER2 6 extended Clipper locking scheme NTXLOCK2.OBJ

+ finished support for COMIX like hyper locking.
This modification enables periodical switch to write locks
by readers to eliminate starvation effect on some systems
where many readers can completely block writer.
By default readers use exclusive lock once per each 16 operations.
+ added optional support for delayed index write locks (flush locks)
in hyper locking modes.
If index RDD can use such locks then write lock can be divided into
two parts:
1) block writers and new readers (write lock)
[prepare index modifications in memory]
2) wait for old readers still active (flush lock)
[write modifications to index file]
[release locks]
This mode reduces time when index is locked exclusively increasing
reader performance and also increase writer performance because
waiting for active readers it can prepare index modifications in
memory.
* harbour/src/rdd/dbfcdx/dbfcdx1.c
+ added support for delayed index write locks (flush locks) in DBFCDX
* harbour/src/rtl/filebuf.c
* automatically change write file locks to read locks when file is
open in readonly mode in POSIX systems.
* harbour/src/vm/classes.c
* disabled inheriting of class variables values from ancestor classes
when new class is dynamically created.
Warning: INCOMPATIBLE!
This modification is not backward compatible and can
interact with some existing code which has to be updated
for new behavior.

* modified some RDD structures to force more strict alignment.
Warning!!! AREA structured modified - all 3-rd party RDDs which
redefines AREA members instead of using AREA structure
directly have to be updated.

It resolves the synchronization problem so now modification in super
AREA structures does not force modifications in source code of
descendant RDDs. It also eliminates possible typos in manual structure
synchronization.

+ added support for VFP tables with NULLABLE fields
+ added new dbFieldInfo() action to check if given field is NULL, f.e.:
? dbFieldInfo( DBS_ISNULL, FieldPos( <cFieldName> ) )
The above modifications were not tested with real VFP files. I do
not have VFP. VFP users should make some real life tests with tables
created by VFP.
* harbour/include/dbinfo.ch
+ added DBI_ISTEMPORARY
* harbour/include/hbapirdd.h
* harbour/source/rdd/wafunc.c
+ added hb_rddCreateTableTemp() C function to create temporary
table which are automatically deleted on close. All indexes and
memo files for such tables are also in temporary files and
automatically deleted on close. Please remember that Harbour uses
OS functions to create temporary files so it's installation dependent
how much disk space is available for them. Some RDDs may also do
not create temporary files but keep everything in memory if they
decide it's more efficient.
* harbour/source/rdd/dbcmd.c
+ added .prg function to create temporary files:
dbCreateTemp( <cAlias>, <aStruct>, <cRDD>, ;
<cCodePage>, <nConnection> ) -> <lSuccess>
Not all RDDs have to support it. It's verified by support for
DBI_ISTEMPORARY dbInfo() action.

! fixed description in header I wrongly copied without updating

+ harbour/tests/hsxtest.prg
+ added test code for HiPer-SEEK indexes
* harbour/source/rtl/filesys.c
+ added new functions: hb_fsExtName(), hb_fsReadAt(), hb_fsWriteAt(),
hb_fsTruncAt() to use with shared file handles.
Please test it in other *nixes. I used pread[64]()/pwrite[64]()
POSIX functions but I do not know if they are available by default
in other supported platforms like MacOSX, BSD, HPUX, SunOS.
If not they I will have to implement some workaround.
* harbour/common.mak
* harbour/source/rtl/Makefile
* harbour/include/hbapifs.h
+ harbour/source/rtl/filebuf.c
+ added set of new file functions (hb_file*()) which are designed to
use with shared file handles and locks (buffers in the future):
hb_fileExtOpen(), hb_fileCreateTemp(), hb_fileClose(), hb_fileLock(),
hb_fileReadAt(), hb_fileWriteAt(), hb_fileTruncAt(), hb_fileSize(),
hb_fileCommit(), hb_fileHandle()
These functions operate on PHB_FILE structure instead of HB_FHANDLE.
Now in POSIX systems they share file handle between aliased or
simultaneously open by other thread work areas. It resolves the
problem with releasing all process FCNTL locks by any close()
operation even on duplicated or open() separately handle.
Now DOS deny flags emulation works in single process even if
BSD locks are disabled (non Linux *nixes).
They also keep internal file lock list what allows to synchronize
threads and aliases with file locks in POSIX systems. In the future
it will be used also for internal locking to synchronize threads
without OS level locks - pseudo exclusive mode in cloned WA.
Finally these structures will be used also for file buffers
which will be shared between aliased WA and threads.

+ added SIx3 compatible triggers support
They should work like in SIx3 with some intentional excpetions:
1) if 4-th parameter exists (PREUSE/GET/PUT) then it's passed by
reference otherwise is not passed at all and PCOUNT() in trigger
functions returns 3
SIx3 do not pass 4-th parameter by reference and if it not
exist then passes 0
2) EVENT_POSTCLOSE is executed after SUPER_CLOSE()
SIx3 executes EVENT_POSTCLOSE just before SUPER_CLOSE()
3) EVENT_UPDATE is executed _ALWAYS_ when DBF is updated also
when WA does not have open indexes
SIx3 executes EVENT_UPDATE only when at least one index is
open without checking if it's updated or not
4) EVENT_POSTUSE is executed from OPEN() method in "DBF" RDD not
from index RDDs so before the indexes are open
SIx3 executes EVENT_POSTUSE after opening indexes
It's possible that I'll change this condition in the future

* Sorry but it's too much modification for full description
cvs diff gives file 785982 bytes length. So I only count the
main things:
! cleand the code (no more warning messages under Linux and GCC and
DOS OpenWatcom) - some of them were real bugs
! cleaned all endian dependend code I've found - now Harbour can be
compiled on LITLE and BIG endian machines - for some other like
PDP ENDIAN it's enough to define proper macros in hbdefs.h
+ added macros for to get/put values in chosen byte order:
HB_GET_LE_[U]INT{16,24,32,64}( pPtr )
HB_GET_BE_[U]INT{16,24,32,64}( pPtr )
HB_PUT_LE_[U]INT{16,24,32,64}( pPtr, nVal )
HB_PUT_BE_[U]INT{16,24,32,64}( pPtr, nVal )
+ added macro HB_CAST_BYTE_NUMBERS_OFF which disables casting in
HB_{GET|PUT}_{LE|BE}_* macros - it's necessary for some platforms
like ALPHA DEC.
! cleaned the code for 64bit machines
* changed all parameters in hb_date* functions (day, month, year, week)
from LONG to int - it doesn't change binary compatibility for 32bit
machines but can cause troubles with compiling the old source
+ changed HB_IT_LONG type to HB_LONG which is mapped to long long
by default for 32 bit machines.
+ change HB_IT_INTEGER to be real 'int' C type not 'short int'
+ added HB_IS_NUMINT() macro
+ added hb_parnll, hb_stornll, hb_retnll, hbretnlllen, hb_itemPutNLL,
hb_itemPutNLLLen, hb_itemGetNLL which operates on LONGLONG
+ added hb_parnint, hb_stornint, hb_retnint, hb_retnintlen,
hb_itemPutNInt, hb_itemPutNIntLen, hb_itemGetNInt which operates on
HB_LONG
+ added HB_PUSHLONGLONG pcode
+ changed compiler and optimizer to use HB_LONG numbers and reduce
conversion from to double which may damage the 64bit number.
+ common functions for string to number conversions for compiler, RTL
and RDD to reduce problems with differ FL values for the same number:
hb_compStrToNum(), hb_valStrnToNum(), hb_strToNum(), hb_strnToNum()
+ common function hb_numRoun() which uses exactly the same algorithms
as string to number conversion for the same reason - please keep
this functions together.
+ hack inside hb_numRound() similar to the one used by CL5.3
+ hb_numInt() which uses uses the same hack as hb_numRound()
+ rewritten number to string conversion
+ some new string manipulation functions hb_strncpy(), hb_strncat(), ...
They works differ the the C one - always set 0 at the end, the buffer
has to be n+1 bytes length, the n is total size of buffer not the
left free space.
! cleaned some code which operates on ASCIIZ string to avoid potential
buffer overflow
+ updated RDD code - it's the first part - in few days I plan to change
workarea structure in both projects - it will break any 3rd party RDDs
so they have to be updated. I want to add SUPERTABLE into workarea
to allow creating new RDD on-line.
! cleaned the bugs with negating integers - on most machines (like x86)
the integers are not 0 symmetric - it means that x = -x does not work
for {INT,LONG,LONGLONG}_MIN (hb_vmNegate, ABS())
+ cleaned error messages to be Clipper compatible.
+ updated build process for .DEB packages - now hb* scripts and shared
libs are created by standard make install
* added new .prg #defines: __PLATFORM__<cPlatfrom>,
__ARCH{16|32|64}BIT__, __LITTLE_ENDIAN__|__BIG_ENDIAN__|__PDP_ENDIAN__
!!! cPlatfrom can have lower letters (for xHarbour compatibility)
If you do not like it please change it.
* others ...
* include/hbapirdd.h
* include/hbrdddbf.h
* include/hbrddcdx.h
* include/hbrddntx.h
* source/rdd/dbcmd.c
* source/rdd/workarea.c
+ Changed fieldname max length handling,
it is now a workarea property. (set by the RDD)
