Make using folly::Singleton easier: names and direct referencing
Summary:
There are times when you want multiple singletons of the same
underlying type -- for instance, a fast and slow request handling
singleton. This diff allows for that with an optional name that
disambiguates multiple singletons of the same type.
In addition, we now also allow direct dereferencing of the
Singleton<Foo> object to get to the underlying singleton. This is most
useful in cases where a singleton is used inside of the same cpp file it
is defined.
Finally, make get() faster by caching the underlying pointer rather than
accessing the shared pointer. If you're using it, you already have a
race condition and hopefully your singleton lifecycle is sane and safe
from problems this may cause.

Fix block overhead estimation in tests

folly/test/ArenaTest.h assumes that goodMallocSize will account
for the block overhead, if the size is +1. However, when compiling
without jemalloc (as, I would imagine, most of our open-source clients
do), goodMallocSize(64 + 1) returns 65, which is less than 64 +
sizeof(Block), and so the tests fail.
I have added a constant to Arena.h which exposes the overhead taken by
the Block, and changed the tests to use that value instead of 1.
(Arena::getTotalSize relies on the totalAllocatedSize_ variable, which
is only non-trivially set in allocateSlow, where the size of the heap is
added to sizeof(Block)).

fbcode: __x__-protect all __attribute__ keywords, mechanically
Summary:
The first (and sometimes 2nd) argument to __attribute__
should begin and end with "__". If it does not, then it
is at risk of conflicting with user cpp-defined symbols.
Don't do that. This change mechanically corrects most
such violations in fbcode. A companion change (see parent task)
adds a lint rule to help keep things clean going forwards.
Define this function to filter the list of file names to which
we will apply the transformations. First, ensure we modify only
C and C++ sources. The second process excludes a few directories
that appear to contain third-party code:
filter() {
grep -E '\.(c|h|cc|cpp|hpp)$' | grep -vE \
'^external/|/unbound/|/gearmand_|(3rd|third.)party|/external/libevent'
}
then, run this command,
git grep -l __attribute__ | filter \
| xargs perl -pi -e 's/(__attribute__ *)\(\(( *[^_]\w+)/$1((__${2}__/g'
inducing changes like this, for each such keyword:
-} __attribute__((packed));
+} __attribute__((__packed__));
That got all but the __format__ archetype arguments like this:
__attribute__((__format__(printf. That final "printf"
keyword should have the "__" prefix and suffix, too.
Run this command to transform those remaining uses:
git grep -l '__attribute__.*__format' | filter | xargs perl -pi -e \
's/(__attribute__ *\(\(__format__ *)\( *(printf|scanf|strftime|strfmon)/$1(__${2}__/g'
That command induces changes like this:
-static inline int __attribute__ ((__format__ (printf, 3, 4)))
+static inline int __attribute__ ((__format__ (__printf__, 3, 4)))
This exercise is useful to avoid spurious name-space conflicts,
especially when the unprotected keyword is used in a header file.
Test Plan:
I've ensured tao builds and passes its tests.
I will watch the arc-run tests.

Enabling folly::Synchronized for non-default constructible objects
Summary:
Currently folly::Synchronized can't be used with non-default
constructible types because copy and move constructors require
creation of datum_ before it's assignment.
To fix this we can initialize them in initializer-list and
handle guard creation using helper constructor
Test Plan:
fbconfig -r folly && fbmake runtests
Fixes compilation error: Synchronized started working for non-default
constructible types in my project(rfe).

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.

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

A generic line-reading callback for communicate()
Summary: There are a couple of places where this behavior is useful, and it's not 100% trivial to implement it from scratch. Adding it to Folly to save people code & bugs.

Factor out string stream re-splitting as StreamSplitter
Summary: This way I can reuse it in Subprocess. It also makes it easy to make a bunch of other convenient tokenization routines (e.g. delimiter-preserving folly::gen tokenizers, file tokenizers, etc, etc).

make folly::Range literal type
Summary:
7.1.5 [dcl.constexpr] / 9 (N3337) requires type to be literal to use it
in `constexpr` object declaration (seems to be not enforced by GCC 4.8?)
Currently `folly::Range<>` fails one of the requirements:

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.

added replaceAt and replaceAll to MutableStringPiece
Summary:
To make MutableStringPiece more usable (and make the
implementation of replace* methods easier) I made sure that
all the const methods (like find) work for MutableStringPiece
in a fashion similar to how they work with StringPiece
(work with everything auto convertible to StringPiece). As
a result this change is pretty susbstatial in LOC, even
though now much happens here.
