The fix is to make "sst" a meyers singleton. This is only a test, and it now works, so not worth seeing if we might actually need folly::Singleton.
There was also a heap use after free:

SUMMARY: AddressSanitizer: SEGV in __GI_strlen
ABORTING
After reading a complete status line with terminal CRLF, the parser attempts to read the next header line. Since the parser does not see a CRLF from the beginning of the header line yet, it gets a nullptr from `readLine`. Constructing a `StringPiece` from a `nullptr` is a segfault.

Summary: `AsyncTransport::UniquePtr` is a resource managing type that manages the lifetime of the underlying socket. It is declared as a member variable of `RocketServerConnection`, which means that the implicit object destructor, which runs after the user defined `RocketServerConnection::~RocketServerConnection`, will take care of destroying the object. Manually destroying the object in the user defined destructor is not only unnecessary, it is incorrect. In particular, `ThriftRocketServerHandler::frameHandler_` borrows the socket_ via a raw pointer. `frameHandler_` is declared after the `socket_`, so under normal destruction ordering this borrow is valid. However, due to the fact that `~RocketServerConnection` manually destroys this, it is possible to end up with a use after free: ``` (gdb) bt #0 0x00007f8c1f6574b8 in folly::DecoratedAsyncTransportWrapper<folly::AsyncTransport>::getPeerCertificate() const () from /data/users/mingtao/tmp/thrift_getx509_coredump/par_unpack/sos/libomnibus.so #1 0x00007f8c11146b4e in apache::thrift::Cpp2ConnContext::getPeerCommonName[abi:cxx11]() const () from /data/users/mingtao/tmp/thrift_getx509_coredump/par_unpack/sos/CppServerWrapper.so #2 0x00007f8c1114690b in apache::thrift::CppContextData::copyContextContents(apache::thrift::Cpp2ConnContext*) () from /data/users/mingtao/tmp/thrift_getx509_coredump/par_unpack/sos/CppServerWrapper.so #3 0x00007f8c1114c2d1 in CppServerEventHandler::callPythonHandler(apache::thrift::server::TConnectionContext*, char const*) () from /data/users/mingtao/tmp/thrift_getx509_coredump/par_unpack/sos/CppServerWrapper.so #4 0x00007f8c1f6684b5 in apache::thrift::rocket::ThriftRocketServerHandler::~ThriftRocketServerHandler() () from /data/users/mingtao/tmp/thrift_getx509_coredump/par_unpack/sos/libomnibus.so #5 0x00007f8c1f972937 in non-virtual thunk to apache::thrift::rocket::RocketServerConnection::~RocketServerConnection() () from /data/users/mingtao/tmp/thrift_getx509_coredump/par_unpack/sos/libomnibus.so #6 0x00007f8c1f97a4fe in apache::thrift::rocket::RocketServerConnection::WriteBatcher::runLoopCallback() () from /data/users/mingtao/tmp/thrift_getx509_coredump/par_unpack/sos/libomnibus.so #7 0x00007f8c202d6f45 in folly::EventBase::loopBody(int, bool) () from /data/users/mingtao/tmp/thrift_getx509_coredump/par_unpack/sos/libomnibus.so #8 0x00007f8c202d81ed in folly::EventBase::loopForever() () from /data/users/mingtao/tmp/thrift_getx509_coredump/par_unpack/sos/libomnibus.so #9 0x00007f8c2026abe4 in folly::IOThreadPoolExecutor::threadRun(std::shared_ptr<folly::ThreadPoolExecutor::Thread>) () from /data/users/mingtao/tmp/thrift_getx509_coredump/par_unpack/sos/libomnibus.so #10 0x00007f8c202d2c74 in void std::_Bind<void (folly::ThreadPoolExecutor::*(folly::ThreadPoolExecutor*, std::shared_ptr<folly::ThreadPoolExecutor::Thread>))(std::shared_ptr<folly::ThreadPoolExecutor::Thread>)>::__call<void, , 0ul, 1ul>(std::tuple<>&&, std::_Index_tuple<0ul, 1ul>) () from /data/users/mingtao/tmp/thrift_getx509_coredump/par_unpack/sos/libomnibus.so #11 0x00007f8c202d2bc4 in void folly::detail::function::FunctionTraits<void ()>::callBig<std::_Bind<void (folly::ThreadPoolExecutor::*(folly::ThreadPoolExecutor*, std::shared_ptr<folly::ThreadPoolExecutor::Thread>))(std::shared_ptr<folly::ThreadPoolExecutor::Thread>)> >(folly::detail::function::Data&) () from /data/users/mingtao/tmp/thrift_getx509_coredump/par_unpack/sos/libomnibus.so #12 0x00007f8c84002801 in std::execute_native_thread_routine (__p=0x7f8bfd03aee0) at ../../../.././libstdc++-v3/src/c++11/thread.cc:80 #13 0x00007f8c844ac20c in start_thread (arg=0x7f8bd6dff700) at pthread_create.c:479 #14 0x00007f8c8428881f in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:95 ``` This diff removes the manual socket reset in `RocketServerHandler` and replaces it with an explicit call to `socket->closeNow()`.

Serialization/deserialization in python is slow. We have an accelerated binary protocol for python but not compact. We should likewise make one for compact.
