* Prevent DOS by asserts in TCP tuning
-Propagates socket option errors from the
tuning functions to the callers.
-Asserts a subset of error conditions during tuning,
excluding external network causes.
-Checks tuning results in 3 call sites and treats
them like failures to connect, accept, etc.
* Fix variable name
* Remove lambda requiring C++11
Solution: The Coverity Static Code Analyzer was used on libzmq code and found
many issues with uninitialized member variables, some redefinition of variables
hidding previous instances of same variable name and a couple of functions
where return values were not checked, even though all other occurrences were
checked (e.g. init_size() return).
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.
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
