- add unlikely hints
- drop unnecessary assertion
- style fixes
There is no need to require the 'more' flag in the provided message
structure be 0 when pulling message from the session.
- Created a new option ZMQ_ROUTER_RAW_SOCK
- Added new raw_encoder and raw_decoder to receive and send messages in raw form to remote client
- Added test case file tests/test_raw_sock.cpp
o To create a raw router sock set the ZMQ_ROUTER_RAW_SOCK option
o ZMQ_MSGMORE flag is ignored for non-id messages
o To terminate a remote connection send id message followed by zero length data message
Do not filter out duplicate subscriptions on the XSUB side of
XSUB/XPUB, so that ZMQ_XPUB_VERBOSE doesn't get blocked by forwarding
devices (as long as the devices all use ZMQ_XPUB_VERBOSE)
REP socket demands at least an empty address stack. The server asserted on (msg_->flags () & msg_t::more) in rep.cpp:75 when receiving a malformed request without empty part.
This patch makes a REP socket to discard and silently ignore such malformed requests.
Visual Studio 2008 compiler defines min/max as macros in its <algorithm> even if <windows.h> is not included at all. This patch defines NOMINMAX to remove these macros and fix compilation on Visual Studio 2008.
This patch fixes the two headers added recently to include our own "stdint.hpp" instead of system <stdint.h> because the latter is not available in Visual Studio versions prior to 2010.
Visual Studio didn’t have <stdint.h> until 2010, therefore we had a bunch of typedefs for int8_t, int16_t and the likes in "stdint.hpp". This patch limits these typedefs to Visual Studio versions older than 2010 and uses compiler-shipped <stdint.h> on 2010 and newer.
This is supposed to become part of the ZMTP/1.1.
The main differences from the ZMTP/1.0 framing protocol are:
- flags field comes first, followed by the length field
- long messages are signaled using a flag rather then 0xff escape
- length field does not include the flags field, 0 is a valid value
Hopefully fixed LIBZMQ-427 - there was a slight typo in the init_address
refactor. The encoder refactoring had also broken pgm_sender and
receiver, but just required updating to use the new functions.
Since ZMQ 2.x does not support subscription forwarding, it's not
possible to use ZMQ 2.x SUB socket to receive messages from a PUB
socket.
This patch adds some compatibility layer so that ZMQ 2.x SUB socket
receives messages from PUB socket.
The new protocol adds support for protocol version and exchanges the
socket type, so that the library can reject a connection when the
sockets do not match.
The protocol was designed so that it's possible to detect and fully
support ZTP/1.0 peers.
When a new connection is set up, peers exchange greeting messages. The
greeting message encodes both the protocol verion and the socket type.
The format of the greeting message is as follows:
greeting = tag1, adaptation, tag2, version, length, socket_type
tag1 = BYTE / 0xff
adaptation = 8 BYTES
tag2 = BYTE / 0x7f
version = BYTE / 1
length = BYTE / 1
socket_type = BYTE
The protocol does not define the value of adaptation field.
When interoperability with ZTP/1.0 peers is required, the adaptaion
encodes, in network byte order, the length of identity message increased
by 1. When adaptaion consists of eight zeros, the current
implementatatio of 0MQ 2.x closes the connection.
This patch supports both ZTP/1.0 and new protocol.
