* harbour/src/rtl/hbznet.c
! do not use DEF_MEM_LEVEL to avoid potential problems when <zutil.h>
is not available
* harbour/contrib/hbnetio/netio.h
* harbour/contrib/hbnetio/netiocli.c
* harbour/contrib/hbnetio/netiosrv.c
+ implemented RPC in HBNETIO protocol
+ added the following client functions:
check if function/procedure exists on the server side:
NETIO_PROCEXISTS( <cProcName> ) -> <lExists>
execute function/procedure on server the side,
do not wait for confirmation:
NETIO_PROCEXEC( <cProcName> [, <params,...>] ) -> <lSent>
execute function/procedure on the server side and wait for
confirmation:
NETIO_PROCEXECW( <cProcName> [, <params,...>] ) -> <lExecuted>
execute function on the server side and wait for its return value:
NETIO_FUNCEXEC( <cFuncName> [, <params,...>] ) -> <xFuncRetVal>
All above functions use default connection set by NETIO_CONNECT()
for RPCs but it's also possible to specify server address and port
in <cProcName>/<cFuncName> just like in <cFileName> parameter in RDD
functions, i.e.:
NETIO_PROCEXISTS( "192.168.0.1:10005:MYFUNC" )
+ added new server side functions to enable/disable/check RPC support:
NETIO_RPC( <pListenSocket> | <pConnectionSocket> [, <lEnable> ] )
-> <lEnabled>
if RPC is enabled for listen socket then connection sockets inherit
this setting.
+ added 4-th parameter <lRPC> to NETIO_LISTEN() function. .T. enable
RPC support in returned listen socket which is later inherited by
connection sockets
* changed protocol version ID - current NETIO clients and servers
cannot be used with old code
* harbour/contrib/hbnetio/utils/netiosrv.prg
* added option to enable RPC support in NETIO server
If you want to make some test then you can execute netiosrv with
non empty 4-th parameter as server, i.e.:
./netiosrv "" "" "" 1
and try this code as client:
proc main()
// pass server address to netio_connect() for non localhost tests
? "NETIO_CONNECT():", netio_connect()
?
? "DATE() function is supported:", netio_procexists( "DATE" )
? "QOUT() function is supported:", netio_procexists( "DATE" )
? "HB_DATETIME() function is supported:", ;
netio_procexists( "HB_DATETIME" )
?
? netio_procexec( "QOUT", repl( "=", 50 ) )
? netio_procexec( "QOUT", "This is RPC TEST", date(), hb_datetime() )
? netio_procexecw( "QOUT", repl( "=", 50 ) )
?
? "SERVER DATE:", netio_funcexec( "DATE" )
? "SERVER TIME:", netio_funcexec( "TIME" )
? "SERVER DATETIME:", netio_funcexec( "HB_DATETIME" )
?
? netio_funcexec( "upper", "hello world !!!" )
return
Please remember that only functions linked with server are available.
If you want to enabled all core functions in netiosrv then please
uncomment this line in netiosrv.prg:
REQUEST __HB_EXTERN__
Have a fun with a new toy. I hope that many Harbour user will find it
very interesting. Please only be careful !!!. This feature allows to
execute remotely _ANY_ code on the server side. _NEVER_ leave open ports
with RPC support for untrusted access.
