      No need to export global instances of folly::AsciiCase(Ins|S)ensitive · 40673e01
      Yedidya Feldblum authored 
      Summary: [Folly] No need to export global instances of `folly::AsciiCaseInsensitive` and `folly::AsciiCaseSensitive`.

Calling code may simply construct instances at will - the compiler will optimize away the object construction since it has only the default ctor/dtor, no storage, and no vtable.

      Make EliasFanoReader and BitVectorReader API more consistent · 2baf3f69
      Giuseppe Ottaviano authored 
      Summary: This diff introduces a few breaking API changes to both EliasFanoReader and BitVectorReader in order to fix some inconsistencies:

- As initalized, `EliasFanoReader` and `BitVectorReader` held a value of `0`, thus if `0` is present in the list `skipTo(0)` would not update the position to `0`, as it happens with any other `skipTo(<first element>)`. This fixes `jumpTo` accordingly.
- `jump(i + 1)` would go at position `i`. Now `reader.jump(i)`'s postcondition is `reader.position() == i`.
- It is now illegal to retrieve `value()` from a reader in an out-of-bounds position (before-the-begin or past-the-end). Validity of a reader can be checked with `valid()`.

      Implement assume() · b6a63714
      Giuseppe Ottaviano authored 
      Summary: In some cases hinting the compiler about conditions that are guaranteed
to be true can help it generate better code. For instance, remove
unnecessary bound checks. Clang has `__builtin_assume` and on GCC we
can simulate it with `__builtin_unreachable`, so better just abstract
both into a function.

      folly: specialise makeFutureWith for functions returning futures · 823a8c01
      Sven Over authored 
      Summary: makeFutureWith executes a function and returns a future containing
set to the function's return value. This diff adds a specialisation
for the case when the function returns some type Future<T>. Instead
of returning Future<Future<T>>, makeFutureWith now just passes
on the future that the function returned, which may or may not have
a value set at this time. In case the function throws,
makeFutureWith returns a Future<T> containing the exception.

With this diff, the following two lines produce equivalent results:
  auto f1 = makeFutureWith(func);
  auto f2 = makeFuture().then(func);
except for the fact that f2 requires an additional temporary
Future<Unit> to be created and destroyed.
