8 years agoRelax HHWheelTimer::destroy assertion to accommodate SharedPtr
Alan Frindell [Tue, 9 Feb 2016 17:44:21 +0000 (09:44 -0800)]
Relax HHWheelTimer::destroy assertion to accommodate SharedPtr

Summary:
HHWheelTimer's auto-pointers are kind of funny.  You can do something like this:

```
HHWheelTimer::UniquePtr p = ...;
// create a SharedPtr from UniquePtr
HHWheelTimer::SharedPtr s(p);
// create another SharedPtr from raw ptr
HHWheelTimer::SharedPtr s(p.get());
// No problem.

If you do this:

HHWheelTimer::SharedPtr p = ....;
// this leaks
```

Why?  Because SharedPtr is only have of std::shared_ptr.  It's the refcounting half.  But when the last SharedPtr goes out of scope, it **does not** invoke HHWheelTimer::destroy().

So code like this is possible/expected:

```
MySweetObj::MySweetObj(HHWheelTimer::SharedPtr s) {
  s_ = s;
  s_.scheduleTimeout(a, b);
}

{
  HHWheelTimer::UniquePtr p = ...;

  obj = MySweetObj(p)

  // But what if I decide to kill p:
  p.reset();
}
```

Since MySweetObj takes a SharedPtr and holds it, it can reasonbly expect that it can schedule timeouts on it, and the HHWheelTimer will not be deleted until it releases the SharedPtr.  This is true, but the above code would hit the assert that count_ == 0.

Instead, relase the check that count_ == 0 only if there are no extra outstanding SharedPtrs.

8 years agofolly/futures: fix early release of non-embedded callbacks
Sven Over [Sun, 7 Feb 2016 13:24:01 +0000 (05:24 -0800)]
folly/futures: fix early release of non-embedded callbacks

Summary:
folly::Future (more precisely folly::detail::Core) can store
callback functors (typically lambdas) up to a certain size
(8*sizeof(void*)) inside the main object. Only bigger functors
are stored in the std::function object in folly::detail::Core,
which will put them on the heap.

The behaviour of folly::Future is slightly different depending
on whether the callback can be embedded in the main object
or not. Small functors will be destructed after the callback
is executed. Functors too big to fit in the lambda space in
the Core object will be deleted when Core is deleted.

Some code assumes that functor objects are deleted as soon
as the callback has been executed. The implementations of
folly::Future::collect and variants do so. If you switch
off this optimisation temporarily (which can be done easily
by setting lambdaBufSize in folly/futures/detail/Core.h to
0), a number of unit tests fail.

Given that the lambda buffer is reasonably large, most
functors can be stored in the Core object. The different
behaviour for very large lambdas may not have been observed.

This diff fixes the inconsitent behaviour.

Firstly, it changes the unit test Future:finish to explicitly
check that the callback functor is deleted after the callback
has been executed. This should be tested, because this
behaviour is assumed in other parts of the futures
implementation (e.g. Future::collect et al.).

Secondly, it adds another unit test Future:finishBigLambda,
similar to Future:finish. The lambda captures much more data
to make sure the lambda won't be stored in the Core object,
but in the std::function object inside Core. The test verifies
that the behaviour is the same, i.e. the callback functor
is destructed after the callback has been executed.

Thirdly, it fixes Core and makes sure that functors of any
size are destructued after the callback has been called. The
new unit test fails without this.

folly: ubsan: replace undefined call through reinterpret-cast fn-pointer with std::function

Summary:
This code casts function pointers to void(*fn)(void*) and calls
functions through that type. Calling functions through a different
pointer type is undefined behavior. Casts were used to avoid memory
allocations.

`std::bind` needs a memory allocation - so it's avoided in EventBase.

  std::function<void()> x = std::bind(fn, args);

`std::function` should use small object optimizations when possible and embed the functor in the body of `std::function`.

On GCC 5.0 and forward small lambdas don't need memory allocations
(lambdas being tiny structures - two pointers in this case - and a
function operator).

  std::function<void()> y = [=] { fn(args); };

On GCC 4.7 .. 4.9 functors for which __is_location_invariant<Func> is
true also don't need memory allocations.

Remove undefined behavior by using a `SmallFunctor` which leverages `std::function`'s small object optimization.

Thread-safe RequestContext putIfAbsent operation

Summary:
Adds a thread-safe putIfAbsent operation to the RequestContext. The current setContextData() is not sufficent to do it safely.
Just like setContextData, this method is unfair, as a high volume of reads will block the spinlock.
