* harbour/src/rtl/hbznet.c
* move hb_znetOpen() parameter validation from HB_INETCOMPRESS()
to hb_znetOpen() - it should help keeping other code using
hb_znetOpen() more simple
* harbour/contrib/hbnetio/netio.h
* harbour/contrib/hbnetio/netiocli.c
* harbour/contrib/hbnetio/netiosrv.c
+ added support for compression and encryption in NETIO connection
streams. Enabling encryption (password) automatically enable also
compression. If necessary user can set compression level to
HB_ZLIB_COMPRESSION_NONE. HB_ZLIB_COMPRESSION_DISABLE used as
compression level removes compression and encryption.
See below for details of NETIO server and client code modifications.
* harbour/contrib/hbnetio/netiocli.c
+ extended NETIO_CONNECT() client side function parameters:
NETIO_CONNECT( [<cServer>], [<cPort>], [<nTimeOut>], ;
[<cPasswd>], [<nCompressionLevel>], [<nStrategy>] )
-> <lOK>
% changed the behavior of NETIO_CONNECT() client side function.
In the previous version this function was connecting to the server
and then disconnecting so it was used to check if connection is
available and to set default connection parameters.
Now it does not disconnect after successful connection so created
connection is keept and can be reused by any pending NETIO_*() calls.
User can open many different connections in the same time.
The connections are recognized by server and port address.
The connections set by NETIO_CONNECT() function can be closed by
NETIO_DISCONNECT() function.
Each repeated call to NETIO_CONNECT() increase reference counter
in the connection stream and need corresponding number of
NETIO_DISCONNECT() calls.
+ added new PRG client side function:
NETIO_DISCONNECT( [<cServer>], [<cPort>] ) -> <lOK>
which closes connections set by NETIO_CONNECT().
+ added support for passing connection password as part of file path
or function name in format:
<server>[:<port>[:<passwd>]]:<filepath|funcname>
i.e.:
192.168.0.1:2941:secret:path/to/file
Please remember that it's only an alternative method of setting
encryption which does not allow to use CHR(0) or ":" in passwords.
User can always set connection using NETIO_CONNECT() function which
will be used in RPC or FILE IO calls. If more then one connection
is set by NETIO_CONNECT() then user can chose the connection using
only server and port. It's not necessary to pass other connection
parameters.
+ added support for UNC paths:
//<server>[:<port>]/<filepath|funcname>
i.e.:
//192.168.0.1:2941/path/to/file
backslashes (\\) are also supported.
* harbour/contrib/hbnetio/netiosrv.c
% moved 1-st login identification from NETIO_ACCEPT() to NETIO_SERVER()
Such version do not block other connection accepting when server
waits for NETIO_LOGIN frame so it improve scalability and also
protect against code which may want to block access to the server
by opening dummy connections.
+ added new parameters to NETIO_ACCEPT() function which allows to set
encryption and compression for new connections:
NETIO_ACCEPT( <pListenSocket>, [<nTimeOut>],
[<cPass>], [<nCompressionLevel>], [<nStrategy>] )
-> <pConnectionSocket> | NIL
+ added new server side function:
NETIO_COMPRESS( <pConnectionSocket>,
[<cPass>], [<nCompressionLevel>], [<nStrategy>] )
-> NIL
which allow to set or change encryption and compression parameters
in existing connections
* harbour/contrib/hbnetio/netiomt.prg
* updated to accept new connection parameters in NETIO_MTSERVER()
function:
NETIO_MTSERVER( [<nPort>], [<cIfAddr>], [<cRootDir>], [<lRPC>],
[<cPasswd>], [<nCompressionLevel>], [<nStrategy>] )
-> <pListenSocket>
* harbour/contrib/hbnetio/utils/netiosrv.prg
+ added 5-th parameter <passwd> which enable encryption with compression,
current syntx is:
netiosrv [<port>] [<inetaddr>] [<rootdir>] [<rpc>] [<passwd>]
For default values use "" in command line for skipped parameters, i.e.:
netiosrv "" "" "" 1 topsecret
* harbour/contrib/hbnetio/tests/netiotst.prg
* enable RPC, compression and encryption in test code
+ added simple code which use RPC to create directory on the server side
Now it's possible to easy create secure NETIO connections and compression
should help in slow connections when big number of data has to be
exchange. In RDD file access it mostly help when tables use long records.
Hope you will find it useful. Please make tests.
