Now maximum index key size is 4082 for 8192 bytes length index pages.
Indexes are critical for database applications so please make
tests with current code and report problems if you find any.

To change page size for newly created index it's enough to call:
hb_rddInfo( RDDI_INDEXPAGESIZE, <nNewSize>,, "DBFCDX" )
DBFCDX accepts page sizes which are power of 2 in from 512 to 8192.
The upper range is my personal decision and can be easy changed
in Harbour source code. 512 is default CDX index page size and
only such indexes can be read by other RDDs.
In some cases bigger pages can increase performance and reduce
index size. In local networks probably 1024 should give optimal
performance because can be transferred in single ethernet frame.
Just make a tests.
; In next step I plan to add support for longer index keys when
bigger pages are used.
* utils/hbmk2/hbmk2.prg
! added -stop fix borrowed from Viktor's branch
* include/hbrddcdx.h
* src/rdd/dbfcdx/dbfcdx1.c
+ added support for large index files over 4GB length.
These are slightly modified CDX indexes which stores index page numbers
instead of index page offsets inside index file. This trick increase
maximum index files size from 2^32 (4GB) to 2^41 (2TB). This index
format is enabled automatically when DB_DBFLOCK_HB64 is used. This is
the same behavior as in DBFNTX and DBFNSX for which I added support
for large indexes (up to 4TB) few years ago.
Warning: new CDX indexes are not backward compatible and cannot be
read by other systems or older [x]Harbour versions.
If you try to open new indexes using older [x]Harbour RDDs
then RTE "DBFCDX/1012 Corruption detected" is generated.
When current Harbour *DBFCDX/SIXCDX RDD open index file
then it automatically recognize type of index file so it
will work correctly with both versions without any problem.
In short words: People using DB_DBFLOCK_HB64 should remember
that after reindexing with new Harbour applications old ones
cannot read new CDX indexes.
; In next step I plan to add support for user defined page size in CDX
index files.

+ extended Harbour FILE IO API and added support for read/write filepos,
directory and link operations.
Read/write filepos support in some systems (i.e. *nixes) needs additional
emulation code. If it's not necessary then this functionality can be
disabled by FXO_NOSEEKPOS attribute. Now this attribute is used by our
RDD code.
* src/rtl/Makefile
+ src/rtl/xfile.c
+ added PRG interface to Harbour FILE IO API

Please remember that not all redirectors have to support all of them.
I.e. MEMIO allows to use directory names in files but does not allow to
create or remove directories. It also does not support file attributes
and times in current implementation though it can be easy added.
HB_XCONFIG() is general function which can be used by redirector
authors to make some special operations which are specific to given
device.
HB_XTEMPFILE() always creates temporary files on local system without
switching to FILE IO redirector. It's intentional behavior.
* src/rtl/fscopy.c
* used Harbour FILE IO API in hb_fsCopy()/HB_FCOPY()
Please remember that HB_FCOPY() always makes operation using current
system when HB_XCOPY() may optimize it moving the operation to low
level subsystem or even other computer i.e. NETIO can do that when
both files are located on the same server.
