Solution: try to detect architecture if building with VC++ and
hardcode pointer size accordingly.
Expressions are not allowed inside declspec intrinsics, which
includes other intrinsics.
Solution: use compiler's alignment attributes instead which is
clearer and less of a hack.
Pointer alignment violations causing crashes on architectures
such as sparc64 and aarch64.
This also avoid triggering ABI checkers as the change is compatible
even though applications that suffer from the bug should rebuild to
take advantage of the fix.
Of course people still "can" distributed the sources under the
LGPLv3. However we provide COPYING.LESSER with additional grants.
Solution: specify these grants in the header of each source file.
Users who need e.g. zmq_curve_keypair() have to remember to include
zmq_utils.h, which is counter-intuitive. The whole library should be
represented by a single include file.
Solution: merge all contents of zmq_utils.h into zmq.h, and deprecate
zmq_utils.h. Existing apps can continue unchanged. New apps can ignore
zmq_utils.h completely.
This is still raw and experimental.
To connect through a SOCKS proxy, set ZMQ_SOCKS_PROXY socket option on
socket before issuing a connect call, e.g.:
zmq_setsockopt (s, ZMQ_SOCKS_PROXY,
"127.0.0.1:22222", strlen ("127.0.0.1:22222"));
zmq_connect (s, "tcp://127.0.0.1:5555");
Known limitations:
- only SOCKS version 5 supported
- authentication not supported
- new option is still undocumented
As libzmq is compiled with optional transports and security mechanisms,
there is no clean way for applications to determine what capabilities
are actually available in a given libzmq instance.
Solution: provide an API specifically for capability reporting. The
zmq_has () method is meant to be open ended. It accepts a string so
that we can add arbitrary capabilities without breaking existing
applications.
zmq.h also defines ZMQ_HAS_CAPABILITIES when this method is provided.
Added modifiers reflect the following properties:
- zmq_msg_gets () does not mutate property parameter
- zmq_msg_gets () returns a pointer to memory the caller should not
modify
Specifically:
* zmq_event_t should not be used internally in libzmq, it was
meant to be an outward facing structure.
* In 4.x, zmq_event_t does not correspond to monitor events, so
I removed the structure entirely.
* man page for zmq_socket_monitor is incomplete and the example
code was particularly nasty.
* test_monitor.cpp needed rewriting, it was not clean.
