--------------------------------------------
bq. Blocking SIGPIPE in backend worker thread is not important since it does
nothing, I agree to discuss it later.
Thank you.
bq. But I have to say use "std::tr1" namespace directly is... inappropriate for
the following reasons: At this time, shared_ptr is already in C++ standard and
"std::tr1" namespace is NOT in C++ standard
tr1 is a really old and well-supported thing. {{unordered_map}} and
{{shared_ptr}} are both part of tr1, and I was using them around 10 years ago
to write C++ code. It's a little weird to hear people refer to them as "C++11
features" since they already existed in tr1 a long time ago.
Still, it seems that you are right that tr1 is not technically "part of the
standard." Or rather, it's part of "a" standard, but not the C++11 standard.
So I will introduce {{std::tr1::shared_ptr}} into the hdfs namespace as you
suggested, and we can do the same for any other tr1 things we add later.
