move EvictingCacheMap to folly
Summary:
adding @agartrell's implementation of EvictingCacheMap to folly. Its a general purpose
cache with LRU eviction. It maintains a doubly linked list threaded throught a hash map using
boost::intrusive. set, get and delete are all constant time operations. It is not thread safe.
Configurability: It allows callers to specify a hasher for the keys, has callbacks for eviction
events and the number of evictions on reaching a capacity limit is configurable. resizing for
a higher capacity though could be suboptimal since index is not resized accordingly and you could
end up with a bad load factor.

Remove constructor version attribute on OS X
Summary:
OS X doesn't support this -- it requires support at the linker
level which OS X just doesn't have. Reasonable OS X compilers will yell
about it, but even the ones that don't are just silently dropping it
on the floor.
So I'm not sure what //we// can do other than just silently dropping
this on the floor too and hoping that everything works.

HHVM build on OS X gets ever so slightly further (runs into

Don't check for thread running in terminateLoopSoon()
Summary:
Consider this use case:
thread 1:
make an evb
create and start thread 2
do some work
evb->terminateLoopSoon()
join thread 2 with a timeout
thread 2:
do some initialization
evb->loop()
Normally, this all works fine. However, if the work thread 1 has to do is sufficiently small, and no external input occurs (one of the thing the evb is doing is listening on a socket), then sometimes, terminateLoopSoon() happens before loop() is called (or at least, before loopThread_.store() happens). isRunning() in terminateLoopSoon() is false, and so stop_ is never set, and event_base_loopbreak() is never called. The join times out, and thread 2 is still running. Removing the isRunning() check gives the desired behavior.

In my ad hoc tests, this fix caused my threads to exit when
I wanted them to exit in a situation like the one above.

Singletons are surprisingly tricky in a codebase where

The basic fbcode use intention is to invoke registration completion in
initFacebook, so users need only declare singletons via
Singleton<ClassName> in their .cpp files.
This diff ties the Singletons into the core Init process, but not hhvm

reserve capacity in toAppend<StringType>(...)
Summary:
I modified the toAppend(args..., StringType* dest) so that
before appending it reserves enough space for data to be appended. It is
still work in progress (floats and doubles are really bad: we only do
very naive approximation of the size). On float like workload we gain
~10% perf, on strings/ints/chars we gain as much as 25% of perf.
Probably on bigger strings it will be even faster. We only modify the
case when toAppend() has more than 1 element to append as it would be
just overhead in case of one argument.

To make MutableStringPiece more usable (and make the

Remove unnecessary and broken hash specializations
Summary:
No need to specialize std::hash for std::basic_string; the STL already does
this. Plus, the specializations were broken in multiple ways:
1. std::hash does not treat const char* specially, so it just hashes the
pointer value (contrasting the old __gnu_cxx::hash, which hashed a C-string)
2. Either way, using __gnu_cxx::hash<const char*> for std::string is broken,
as it won't hash anything past the first null byte.
Also, make sure fbstring gets the same (full) specializations as std::string
does in the standard.
Test Plan: fbconfig -r folly && fbmake runtests_opt, also tests in tupperware/agent which is still using __gnu_cxx::hash_map with string keys.

make `folly::Formatter` extendible
Summary:
on advice of @tudorb, move most of `folly::Formatter` into `folly::BaseFormatter` so that we can use compile-time polymorphism to provide different types of Formatters.
I wasn't able to get the recursive formatter to be polymorphic -- whenever I tried to convert `class FormatValue<Formatter<containerMode, Args...>, void>` into `class FormatValue<BaseFormatter...`, `FormatTest.cpp:Test(Format, Nested)` wouldn't compile because it couldn't find the template. @tudorb, if you have an easy fix for this, lmk, otherwise I'm (reluctantly) okay with requiring that `Formatter`s define their own nesting `FormatValue`.
phew. the last time I did this sort of metaprogramming was over 5 years ago in perl. Doing it in C++ is... interesting.

Summary:
Instead of returning a Later, `via` returns a cold future.
This works without keeping a backreference like Later does, because an inactive Future will always activate on destruction. Alternatively we could have an extra Promise, a la Later, and pass that along like Later does, and require launch() at the end (though, implicit launching on destruction would be an option there too).
If you think this approach is viable I'll clean it up on Wednesday: make sure all the calling sites work, etc.

(wangle) Future/Promise detachment
Summary:
Bring a bit more sanity to the lifetime. Now Future and Promise detach by calling the respective methods on State, and they do it during their destruction only. State manages its own lifetime.
Besides being cleaner, this also sets the stage for cancellation (where we'll need Future to hang on to its reference to State after setting the callback), and for folding in Later (we will have a bool for whether the future is hot and hold off executing the callback if it isn't).
Also cleans up various things I noticed while auditing the code for usages of `state_`.

All the unit tests still pass.

(wangle) s/continuation/callback
Summary: The word "continuation" is too ambiguous. Prefer callback (except where we are actually talking about CSP continuations in the README).
Test Plan: Still builds. Nothing external is or should be calling `setContinuation`. But I'll wait for contbuild anyway.

Fix bizarre optimization
Summary:
I have no idea why the compiler is gettings its britches in a bunch because a unit test has a predictable output. Really, gcc?!
But whatever, avoiding inlining by putting it in the cpp file solves it.
