      Fix leak when calling AsyncSSLSocket::cancelConnect() · 3289d2ed
      Eric Hammerle authored 
      Summary: AsyncSSLSocket::connect() creates a new instance of AsyncSSLSocketConnector referred with a raw pointer and passes it to AsyncSocket::connect(). AsyncSSLSocket assumed a callback irrespective of connection success or failure so that this raw pointer will be properly disposed off.  However currently, if a connect attempt is cancelled the parent class may end up clearing the connect callback without invoking a connection error, thereby causing a leak. Since the cancelConnect() function also cancels the callback, the raw pointer should be cleaned up during cancellation.

Note, this is not an undefined behavior, but usually is unintentional. In this case it's intentional, add an explicit static_cast to the destination type.

      hazptr: Use executor for default domain asynchronous reclamation · 78cfa5e5
      Maged Michael authored 
      Summary:
Add support for using an executor for asynchronous reclamation.

This enables doing asynchronous reclamation on a dedicated executor, which serves two purposes:
(1) Avoid unpredictable latencies for regular thread operations (that happen to trigger synchronous reclamation).
(2) Avoid deadlock that may arise from regular threads running deleters that may require resources held by such threads.

By default the QueuedImmediateExecutor is used.
A member function set_executor allows the use of different executors.
The intent is to use a thread pool executor.
In order to avoid cyclical dependency, subsequent diffs (1) add in a separate library a function make the default hazptr domain use a thread pool executor and (2) add a call to such function to folly/init.

      Summary:
[Folly] Ensure global inits in Random are static-safe by using the machinery of `static` local variables.

The default mutex type used with `once_flag` is `SharedMutex`, but that mutex type is not trivially-destructible. An alternative mutex type might be trivially-destructible, such as `MicroLock`, so an alternative solution could be to use `once_flag` with `MicroLock`.
