Also, in C++11, you no longer need to avoid the '>>' in Template1<Template2<Template3>>.

I was just about to ask why the space is there...

@paveljanik because >> is an operator. But yes with c++11 this is apparently parsed differently so will remove the space.

Do we need an empty destructor?

On second thought, I'm going to keep it, the precondition comment is still relevant.

Decided to forget about using std::move to move items conditionally into the queue, the resulting code was too complex, the old code is cleaner. |

ut ACK, other than the little nit |
Use std::unique_ptr for handling work items. This makes the code more RAII and, as mentioned in the comment, is what I planned when I wrote the code in the first place.
More useful error reporting.
No need for boost here.
Thanks to Cory Fields for the idea.

Creating the unique_ptr here defeats the purpose of the emplace :)
Passing it item directly would mean that the unique_ptr would be constructed in-place. As is, it's moved instead.
Not worth worrying about, just pointing it out.

Yes by all means feel free to improve this further.

Small httpserver.cpp backports Also includes a change to the `uiInterface.NotifyBlockTip` signal API. These remove merge conflicts from subsequent backports for `sync.h`. Cherry-picked from the following upstream PRs: - bitcoin/bitcoin#6859 - bitcoin/bitcoin#7112 - Only the non-QT changes. - bitcoin/bitcoin#7966 - bitcoin/bitcoin#8421 - We already backported the second commit in #2555

std::unique_ptrfor handling http work items, andstd::moveto move them into and out of the queue.This makes the code more RAII and, as mentioned in the comment, is what I planned when I wrote the code in the first place.
