Revert "Problem: mis-detection of threadsafe_static_init causes test failures" 2018-03-07 15:03:07 +01:00

9bd2d3f937 Problem: mis-detection of threadsafe_static_init causes test failures 
Solution: do not rely __cplusplus >= 201103L to detect whether the
compiler supports thread safe static initialisation, but check only
the proper feature preprocessor macro.
GCC introduced it in version 8, and Clang in version 6.

e0b1992dd7 Problem: build broken with gcc-4.7 
Solution: initialise variable in options.cpp to dummy value to fix
compiler complaint:

 src/options.cpp: In function
  'int zmq::do_setsockopt_int_as_bool_strict(const void*, size_t, bool*)':
 src/options.cpp:121:5: error: 'value' may be used uninitialized in
  this function [-Werror=maybe-uninitialized]
 src/options.cpp: In function
  'int zmq::do_setsockopt_int_as_bool_relaxed(const void*, size_t, bool*)':
 src/options.cpp:135:31: error: 'value' may be used uninitialized in
  this function [-Werror=maybe-uninitialized]

Problem: enormous memory increase due to zero copy decoding

fcbd2a5710 Problem: enormous memory increase due to zero copy decoding 
The zero copy decoding strategy implemented for 4.2.0 can lead to a large
increase of main memory usage in some cases (I have seen one program go up to
40G from 10G after upgrading from 4.1.4). This commit adds a new option to
contexts, called ZMQ_ZERO_COPY_RECV, which allows one to switch to the old
decoding strategy.

78aa9b1983 Support addressing TIPC Port Identity 
ZeroMQ currently supports location independent addressing using TIPC
Port Names with tipc://{type,instance}. This commits adds support for
connecting and binding using TIPC Port Identity addresses. To connect
using Port Identities the expected format is tipc://<Z.C.N:Ref>, e.g.
"tipc://<1.2.3:123123>". To bind using TIPC Port Identities the expected
format is "tipc://<*>".

d0e01b4bb2 Problem: regression with "select" on *nix (#2940) 
* Problem: build failure with select as polling mechanism

Solution: cast mailbox_handle argument to (poller_t::handle_t) like in
the reaper thread class.

* Problem: build failure due to INT_MAX use without include

Solution: include limits and climits in src/select.cpp where INT_MAX is
used

* Problem: build failure due to unused variable in select.cpp

Solution: move the declaration of int rc inside the ifdef block where
it is actually used

* Problem: reference to wrong variable in select.cpp breaks build

Solution: fix it

* Problem: family_entry_t constructor has no body, build fails on *nix

Solution: add empty inline function in the struct

* Problem: no test coverage for poll and select

Solution: add Travis jobs for them on Linux

* Problem: Travis jobs cannot run in container infra

Solution: set sudo: false as it is not required anymore
