      Pure C++ for TSAN annotation wrappers · 799a718f
      Yedidya Feldblum authored 
      Summary:
[Folly] Pure C++ for TSAN annotation wrappers, v.s. using the preprocessor.

The implementation uses the preprocessor in order to support platforms without weak symbols, but the interface is now pure C++.

      cmake: explicitly link against libatomic when required · 4b0c7ff2
      Adam Simpkins authored 
      Summary:
When using clang with libstdc++ `-latomic` must be explicitly specified
as part of the link command in order to get some of the symbols required
for C++ std::atomic support.

The old autoconf-based build did have this check (added in github commit
60a5636b, D2519083).  However this check was missing from the
CMake-based build.

      Add a FOLLY_ASAN_ENABLED macro · af21e4d6
      Adam Simpkins authored 
      Summary:
Add a new macro to track if folly was compiled with ASAN enabled.  This
is in addition to the existing FOLLY_SANITIZE_ADDRESS macro, which
reports if the current .cpp file is being compiled with ASAN enabled.

In particular, these macros differ in open source builds if folly was
compiled without ASAN enabled, but some of its headers are being
included from downstream libraries that are being built with ASAN
enabled.

Previously several headers would define structures differently based on
`FOLLY_SANITIZE_ADDRESS`, which meant that different .cpp files would see
different definitions of these structures.  `FOLLY_ASAN_ENABLED` is generally
the correct macro to use for situations like this.

This diff fixes F14Table.h to use FOLLY_ASAN_ENABLED, but several other
headers probably should also be updated in the future.

I did not change the behavior of FOLLY_SANITIZE_ADDRESS, since it appears to
be used by several projects outside of folly, and they expect it to report if
their code is being compiled with ASAN enabled.

At the moment the open source build does not support compiling with ASAN,
so FOLLY_ASAN_ENABLED is always disabled in open source builds.

      Summary: Pends the freeing of the internal SSL until the socket is finally destroyed. This ensures that the async job can write out the result and call the socket's callback. This also always calls restartSSLAccept in order to let it handle errors and cleaning up of async jobs.

      Detect `std::launder` in libc++ 6 (and Xcode 10) (#948) · fb28875b
      Paul Rosania authored 
      Summary:
Fixes #947.

>libc++ 6+ (and Xcode 10's libc++, which seems to be based on it) adds std::launder, but does not define the __cpp_lib_launder feature-test macro. As a result, folly's lang/Launder.h concludes std::launder is missing and defines its own implementation. Since std::launder does actually exist, ADL causes 'ambiguous call' errors whenever a standard library type like std::pair is laundered within the folly namespace. (This breaks compilation of folly's futures, for example, and I believe it will cause compilation issues anywhere else F14Map is used, since it launders std::pair in its F14Policy.)
