wangle::detail::FSM
Summary:
spaghetti-monster
Finagle uses a nifty state machine pattern in `Promise.scala`. Each state carries its data with it, then you switch statements with a simple state `cas`, within the functions (which are the transition inputs). See https://github.com/twitter/util/blob/master/util-core/src/main/scala/com/twitter/util/Promise.scala#L133-L139 and https://github.com/twitter/util/blob/master/util-core/src/main/scala/com/twitter/util/Promise.scala#L604-L635 for example.
I was thinking we could do something similar in C++, though we don't quite have the same luxury of type cases like scala. (Although as an aside I found this really cool paper on implementing type cases in C++, it's kind of evil but very cool. http://www.stroustrup.com/OOPSLA-typeswitch-draft.pdf)
I was looking at having a union of the different state classes, e.g.
union U {
State base;
Done done;
Waiting waiting;
...
};
and then you could use the memoized `dynamic_cast` trick in that paper to make a fairly efficient type case (and fairly readable, depending on how evil you want to get with the macros). However, `dynamic_cast<Done*>(&u.base)` blissfully segfaults. I'm not sure if this is something that should work and it's a compiler bug, or whether trying to (ab)use a union this way is against some arcane C++ rules. @hannesr suggested maybe a variant type might work. We can also do memory mangling on our own if it comes to it - however those are all more advanced techniques to play with at a later optimization time.
So instead, I went for a this-is-context helper base class. The mutable context is just `this`, and you inherit from `FSM`.
The magic macros make it more succint to lay out state transitions. See the tests for examples. Maybe in the future we can get really clever and find a way to generate state machine diagrams from code using this, especially when macros are being used.

Go back to a regular mutex
Summary:
D1428504 changed the `detail::State` mutex to be a recursive mutex to get around deadlock in our project, where a promise was being freed within a callback, racing with the mechanics happening while fulfilling the promise in the first place. At least, that's what seemed to be happening. I couldn't easily pull it into gdb because it's a python test.
I made my own test to repro, and it did in fact deadlock:
TEST(Future, DISABLED_promiseDestructedDuringCallback) {
auto p = folly::make_unique<Promise<void>>();
p->getFuture().then([&](Try<void>&&) {
// shouldn't deadlock.
p.reset();
});
p->setValue();
}
However, although this code fixes our project it does not fix this code, which still fails (not with a deadlock, but with a promiseAlreadyFulfilled exception). So whatever our project is doing is a bit more intricate.
I'm not convinced that even allowing this is ok - so I suspect out project is doing something bad. However, I also think it's probably bad to hold the lock while doing the callback so I am presenting this as a fix/compromise.

The emulated futex (not used on Linux) has an optimization to defer
notification until after the bucket mutex has been unlocked, to avoid
lock collisions between the waiter and waker. That code will have a
use-after-free problem if the waiter's condition_variable has a spurious
wakeup, which is allowed by the spec. That code also doesn't do
anything about contention between multiple waiters.
This diff adds a mutex to each wait node, relieving the waiters from
having to acquire the bucket lock on wakeup. Rather than trying to
perform a racy late notification, we just make sure to release the node
lock immediately after calling notify_one, which seems to have the
desired effect.

add emulation of futex() for non-Linux systems
Summary:
Inside the Linux kernel, futex() works by hashing the source
address to a fixed set of wakeup lists. When using folly on non-Linux
systems we can emulate something similar by using std::mutex and
std::condition_variable.
Emulating futex() using higher-level APIs is less crazy than it sounds,
because the emulated futex still provides the advantages of the real
one: it allows all of the fast-paths of a new synchronization construct
to be inlined; it is space efficient, taking only 1 word and allowing
the caller to encode state into all of the word's bits; and it avoids
system calls unless a thread actually needs to be put to sleep or
woken up. Think of this as a way of boostrapping something with the
same properties as futex() on platforms that don't expose it publically.
(Presumably these platforms have private APIs that do something similar.)
This diff moves all of the Linux-specific futex stuff into Futex.cpp,
where it is gated by #ifdef __linux__. It also adds an emulated
implementation. The emulated futex will be selected by default on
non-Linux platforms, or it can be used on Linux by using an Atom template
type of folly::detail::EmulatedFutexAtomic. This means, for example,
that you can test MPMCQueue on top of the emulated API by instantiating
a MPMCQueue<ElemType, EmulatedFutexAtomic>.
As a bonus, this refactoring provides a small speed boost by removing
an unnecessary evaluation of the errno macro in the success path of
futexWait.
Test Plan:
1. existing unit tests
2. new unit tests (including tests of Futex users)
3. compile Futex.cpp on OS X (some other build failures still occur)

subscriptions
Summary:
I'm not thrilled with this implementation, but it mostly works. The big bummer is enforcing that Observables are held in shared_ptrs, or rather that enforcing that condition is impossible.
The protected constructor / friended dumb make_shared() pattern is clunky, and it'd be really easy for a subclasser to shoot themselves in the foot or even in the face.
It does seem like maybe Observable should be made an interface again, and all these details should live in a subclass (FanoutObservable?) where the restriction are super obvious. For instance, the langtech AudioStream object doesn't need all this crap because it overrides subscribe() without using the observer list, but it subclasses anyways.
I'm noodling another approach that (if it works) will not require the shared_ptr dancing, but will probably have some additional overhead... the observable would have to keep track of the subscriptions itself.
I like the RAII subscriptions, though perhaps subscriptions should be optional as long as it's clear that your subscription will last forever it you opt out of them.

RFC: future executor
Summary:

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

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.

D1534506 as this seemed different enough for a new diff
Similar to previous diff but attempts to reuse a common thread management process between cpu and io bound thread pools. Also sets the stage for other common functionality, e.g. stats, monitoring, timeouts, and so on
Here is some output from the queue benchmark in common/concurrent with both of these pools added (changes to BM not in this diff): https://phabricator.fb.com/P16308560

Add non-strict mode to folly::Singleton
Summary:
It is difficult to guarantee every binary can call
registrationComplete; for now, support a mode where we don't enforce the

Make TSocketAddress use folly::IPAddress
Summary:
Step 1 of moving TAsyncSocket and friends to folly.
folly::IPAddress changes (can split these off if requested):
* isLoopback looks for a single address, as opposed to subnet
* For V6, isPrivate & isLoopback don't seem to check mapped addresses
TSocketAddress changes:
* Make union use folly::IPAddress instead of sockaddr struct. external_ bool to tell if using AF_UNIX instead.
* manage the port and scope/zone info ourselves
