These options are confusing and redundant. Their names suggest
they apply to the tcp:// transport, yet they are used for all
stream protocols. The methods zmq::set_tcp_receive_buffer and
zmq::set_tcp_send_buffer don't use these values at all, they use
ZMQ_SNDBUF and ZMQ_RCVBUF.
Solution: merge these new options into ZMQ_SNDBUF and ZMQ_RCVBUF.
This means defaulting these two options to 8192, and removing the
new options. We now have ZMQ_SNDBUF and ZMQ_RCVBUF being used both
for TCP socket control, and for input/output buffering.
Note: the default for SNDBUF and RCVBUF are otherwise 4096.
This option has a few issues. The name is long and clumsy. The
functonality is not smooth: one must set both this and
ZMQ_XPUB_VERBOSE at the same time, or things will break mysteriously.
Solution: rename to ZMQ_XPUB_VERBOSER and make an atomic option.
That is, implicitly does ZMQ_XPUB_VERBOSE.
Solution: bump CMake required version to 2.8.12 to avoid:
CMake Error at tests/CMakeLists.txt:110 (target_include_directories):
Unknown CMake command "target_include_directories".
Solution: be more explicit in the code, and in the zmq_recv man
page (which is the most unobvious case). Assert if length is not
zero and buffer is nonetheless null.
There's no value in this as the same pattern is repeated in several
places and it's fair to expect people to understand it.
Solution: revert to the old, one-liner style.
It is poor style for test cases to use the internal API (i.e.
libzmq classes or header files), as this code serves the purpose
of teaching developers how to use the library (it doesn't do this
very well, it's an ambition).
Also, including headers in src/ creates problems when compiling.
Solution: remove use of src/macros.hpp.
used static_cast<signed int> around WSA_WAIT_FAILED as it is an unsigned implicitly defined as (0xFFFFFFFF ion winbase.h) and causes a comparison error.
removed use of c++11 style initialiser list for 'sockaddr addr { 0 }' and changed it to 'sockaddr addr = { 0 }'
Solution: checkout stable branch instead.
Several warnings are printed when building from the master branch,
and developers recommend using the stable branch instead.
Took me over 8 hours to track down the cause of bizarre link
errors when building with libsodium. The VS project files are
not simple things.
Note to self and other maintainers: when someone is obviously
out of their depth, do not merge their changes to build scripts
without cynical appraisal.
Solution: undo the damage.
