Solution: use pthread API to set the name. For now call every thread
"ZMQ b/g thread". Would be nice to number the I/O threads and name
explicitly the reaper thread, but in reality a bit of internal API
churn would be necessary, so perhaps it's not worth it.
This is useful when debugging a process with many threads.
Solution: set SOVERSION in CMakeLists to match the SONAME generated
by libtool so that there is no mismatch between the output of the
*NIX build systems.

Solution: use only Libs.private to avoid breaking application builds.
Even though Requires.private are supposed to be parsed only if
pkg-config is called with --static, the --cflags parameter is enough
to trigger the parsing, causing build failures for applications that
do not (and should not) depend on libzmq's dependencies.
Solution: add dependencies, if necessary, to the .private Libs and
Requires field of the pkgconfig file at build time.
This way pkg-config --static --libs libzmq will correctly print
dependencies if they were used to build the static libzmq.a library.
Solution:
Add CMake option called WITH_MILITANT so that it aligns with the Autotools
build infrastructure; enabling this option defines ZMQ_ACT_MILITANT, which
enables assertions should malformed requests make their way into
zmq_setsockopt(3) or zmq_getsockopt(3).
Solution: add macro in ZMQSourceRunChecks.cmake and optionally
include the TIPC sources if the support is available.
More importantly, only run the TIPC tests if the support is there.
Solution: Add precompiled flags to CMakeList.txt for faster compiles
+ bonus - removed compilation warning on Windows by adding
add_definitions (-D_WINSOCK_DEPRECATED_NO_WARNINGS)
Solution: it's a lot of work to define the tests in project.gyp
so I did this using gsl to generate the JSON, from a small XML
list of the test cases.
To keep this, and the hundreds of .mk files, away from the root
directory, I've moved the gyp files into builds/gyp, where you
would run them.
It all seems to work now. Next up, OS/X and Windows :)
- they have no copyright / license statement
- they are in some randomish directory structure
- they are a mix of postable and non-portable files
- they do not conform to conditional compile environment
Overall, it makes it rather more work than needed, in build scripts.
Solution: clean up tweetnacl sauce.
- merged code into single tweetnacl.c and .h
- standard copyright header, DJB to AUTHORS
- moved into src/ along with all other source files
- all system and conditional compilation hidden in these files
- thus, they can be compiled and packaged in all cases
- ZMQ_USE_TWEETNACL is set when we're using built-in tweetnacl
- HAVE_LIBSODIUM is set when we're using external libsodium
This happens if you first configure with autotools, and then run
cmake. The problem is that the compiler finds the old src/platform.hpp
before looking for the one generated by CMake. Further, there are a
set of macros that configure passes via the command line, yet CMake
passes via platform.hpp. (HAVE_xxx for pollers, at least.) This means
you can't do a CMake build using the autotools platform.hpp.
Solution: remove any src/platform.hpp when running cmake. This is a
workaround. I'll fix the inconsistent macros separately.
It's unclear which we need and in the source code, conditional code
treats tweetnacl as a subclass of libsodium, which is inaccurate.
Solution: redesign the configure/cmake API for this:
* tweetnacl is present by default and cannot be enabled
* libsodium can be enabled using --with-libsodium, which replaces
the built-in tweetnacl
* CURVE encryption can be disabled entirely using --enable-curve=no
The macros we define in platform.hpp are:
ZMQ_HAVE_CURVE 1 // When CURVE is enabled
HAVE_LIBSODIUM 1 // When we are using libsodium
HAVE_TWEETNACL 1 // When we're using tweetnacl (default)
As of this patch, the default build of libzmq always has CURVE
security, and always uses tweetnacl.
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".
VMCI transport allows fast communication between the Host
and a virtual machine, between virtual machines on the same host,
and within a virtual machine (like IPC).
It requires VMware to be installed on the host and Guest Additions
to be installed on a guest.
This is due to the mangled include of platform.h, which was to make
CMake happy.
Solution: in CMakeLists.txt, define USING_CMAKE and then look for
platform.h in current directory if that is defined, else look in
../src/ as one would expect.
A memcpy is eliminated when receiving data on a ZMQ_STREAM socket. Instead
of receiving into a static buffer and then copying the data into the
buffer malloced in msg_t::init_size, the raw_decoder allocates the memory
for together with the reference-counter and creates a msg_t object
on top of that memory. This saves the memcpy operation.
For small messages, data is still copied and the receive buffer is reused.
Solution: increased to 4096 by default for all MSVC builds, for MinGW,
and for CMake.
Note: this is a speculative change, it needs confirmation before we
can keep it. Particularly, there is some doubt that changing this in
libzmq will affect upstream applications using libzmq.dll.
fork() support is optional and its availability is correctly detected at
contfigure time.
But test_fork was all always built, preventing build for targets that do
not provide fork() from building successfully.
This pacth fixes the CMakeLists.txt on this point.
