lib/replace: Remove #undef TCP_NODELAY

2019-06-18T06:47:05+00:00

A duplicate define warning is better than not defining this at all.

Similar to a patch Torsten Werner submitted to the Samba Bugzilla in
2005.

Not tested on HP-UX

reverts fc84e916f628b4fb6f6667ad45d0ced0e9134b23 that was still present in

replace: add checks for atomic_thread_fence(memory_order_seq_cst) and add possible fallbacks

2018-07-24T15:38:26+00:00

This implements a full memory barrier.
On ubuntu amd64 with results in an 'mfence' instruction.

This is required to syncronization between threads, where
there's typically only one write of a memory that should be
synced between all threads with the barrier.

Much more details can be found here:

https://gcc.gnu.org/onlinedocs/gcc-7.3.0/gcc/_005f_005fsync-Builtins.html#g_t_005f_005fsync-Builtins

The main one we use seems to be in C11 via stdatomic.h,
the oldest fallback is __sync_synchronize(), which is available
since 2005 in gcc.

build: bundle and reduce huge number of EA function tests

2018-07-03T11:24:51+00:00

It's sufficient to check for one basic function of an EA implementation and a
use a single ifdef for each group of EA functions. This makes more sense than
checking for each EA function on each platform.
