- Lowercase all commands
- Unify indent to 2 spaces
- Remove spaces around brackets
- Remove repitition of condition in else(...) and endif(...)
Note: (re-)running CMake did not change the content of the generated files
Use ZeroMQ_SOURCE_DIR, ZeroMQ_BINARY_DIR instead of CMAKE_SOURCE_DIR, CMAKE_BINARY_DIR, which allows libzmq to become an "add_subdirectory" target (with static build).
Otherwise, building unittest_xxx would complain header files not found.
Solution: replace it with the ip_resolver code shared with the TCP
address code
It simplifies the UDP parsing code and makes it behave more like the
TCP counterpart, in particular it's not possible to connect to hosts
by name and bind by NIC names.
It also adds support for "*" port resolving to 0 (useful to let the OS
allocate the port number).
Solution: return an error in this situation but still allow using an explicit
"0" if somebody really wants to connect to port 0.
This shouldn't break any existing code because a "*" port was already rejected
in an early test in the TCP path in zmq::socket_base_t::connect.
reuse
Solution: extract into functions defined in ip.hpp
Problem: signaler_t::make_fdpair not reusable
Solution: move make_fdpair to ip.hpp
Problem: epoll worker with no fds cannot be stopped
Solution: use interruptible epoll_pwait call
Problem: insufficient unit tests for poller
Solution: add test cases
