RFC: future executor
Summary:
not necessarily for commit but i was playing around a bit with this today to see what it might look like, so i figured i'd put it up
i assume this shenanigan isn't remotely safe (threadwise) without some extra magic... @fugalh we chatted about this last time i was in mpk a bit.
maybe addFuture could take an executor to make sure the promise is fulfilled on the correct thread, or something.
you'd have to reimplement timeouts via this executor or via futures if you wanted to get them via the futures channel, which makes sense anyway as this could be used with any Executor and not just ThreadPoolExecutor which owns that implementation
also specialized makeFutureTry to take functions that return futures but treat them like they return the contained types, so fulfil() can be used liked then()
this specialization could just as easily be done on fulfil() itself if we wanted.

rfc : -Wshorten-64-to-32 warnings in folly liger dependencies
Summary:
This is not a fix but me seeking advice here. The context here is that in liger (our common network
stack for mobile platforms), we saw bugs due to truncation and want to enable these warnings. To find those in our code,
I had to first resolve the folly ones. I just got around by making the truncation explicit so that I can get to real errors.
Ideally I would like owners to examine each case and fix the original/accept the explicit truncate if its intended. Let me
know what you think. The last (least preferred) is for us to keep this as a liger only change. We have a couple of ways to
do that but it would be nice to fix.
N.B : this covers only liger dependencies

We considered it circular if we tried to create a singleton

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
Summary:
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.

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.
Test Plan:
HHVM build on OS X gets ever so slightly further (runs into
other issues). HHVM build in fbcode still seems to build folly okay
(didn't wait for it to finish fully).

always log from LOG_EVERY_MS if interval is <= 0
Summary:
This diff changes LOG_EVERY_MS so that if the specified
interval is zero or negative, no clock call is made and LOG(severity) is
always called. milli_interval is copied into a temporary to avoid
double-evaluation.
Test Plan:
1. unit tests
2. new unit test
