drbob bb10b6b400 Added first version of RPC system for external control of retroshare-nogui. ... The protocol message format is as follows: [HEADER: 16 bytes: 4 x Network Order uint32_t][ VARIABLE LENGTH BODY ] [ MAGIC_CODE ] [ MSG_ID ] [ REQ_ID ] [ BODY_SIZE ] [ ........ BODY ......... ] MagicCode = 0x137f0001 ... this will be incremented for new versions of the protocol. MsgID = Corresponds to the format of the Body. ReqID = Generated by Requester, Returned in Response, make sure its unique. (undefined behaviour for duplicates) BodySize = Byte Length of Body. The Body will consist of a protobuf encoded message. For the moment, the RPC server just ECHOs the request back to the sender - for testing purposes. Usage: * Create SSH connection to retroshare-nogui. * Create Request Message(s), and send over SSH channel - You can send as meny requests as you want. * They will processed, and responses sent back (potentially in an arbitary order). Specific Changes here: * Modified rssshd to support arbitary recv/send applications. (interface is RpcComms). * Added rpc directory, with server, setup and echo service. * Modified Menu System to use the new interface to rssshd * Wrote new matching interface for Terminal Usage. - NOTE: Strange BUG in Terminal version.... causes stderr to disappear. TODO. * Added -C commandline option to switch on RPC system. This is the first version - so I expect there will be bugs. Please report for a prompt fix! git-svn-id: http://svn.code.sf.net/p/retroshare/code/branches/v0.5-gxs-b1@5444 b45a01b8-16f6-495d-af2f-9b41ad6348cc		2012-08-20 14:59:41 +00:00
