Fix a bad bug in folly::ThreadLocal (incorrect using of pthread)

Summary: Fix incorrect using of pthread in folly::ThreadLocal.

The root of the trouble (see man pthread_key_create):
"At thread exit, if a key value has a non-NULL destructor pointer,
and the thread has a non-NULL value associated with that key,
the value of the key is set to NULL, and then the function pointed to is called
with the previously associated value as its sole argument."

At thread exit we need to recover the thread-specific threadEntry
otherwise the subsequent calls of getThreadEntry may recreate it
(what actually DOES  happen in the test ThreadLocalPtr.CreateOnThreadExit)
and the newly created threadEntry will "leak". It will live longer than the corresponding
thread violating the internal invariant of StaticMeta and also it will break

Nick Terrell [Fri, 31 Jul 2015 16:57:00 +0000 (09:57 -0700)]
Overload on dynamic object reference type.

Summary: There are a bunch of methods in `folly::dynamic` that return a
reference to a sub-object, e.g. `getString()`.
These methods are a bit unsafe because it allows you to write code with dangling
references when the `folly::dynamic` object is an rvalue:

  auto& obj = parse_json(some_string).at("key");

However, the bigger win is that when we have an rvalue `folly::dynamic`, such as
returned by `getDefault(...)`, we can move the sub-object out:

  auto obj = parse_json(some_string).at("key");
  auto str = obj.getDefault("another-key", "").getString();

In the first line, the subobject is copied out when it could be safely moved out.
In the second line `getDefault(...)` copies the dynamic sub-object out, and then
`getString()` copies the string out, when the string could be moved.

Also in the case of `getDefault()` being called on a rvalue, we can move the
sub-object out.

9 years agoAdd support for MSVC in asm_pause in Portability.h

Add support for MSVC in asm_pause in Portability.h

Summary: This implements support for `asm_volatile_pause` and `asm_pause`, as defined in `Portability.h`, for MSVC.
This is needed because MSVC x64 doesn't support inline assembly.

Adjust a literal in AtomicHashMap.h to be correctly sized

Summary: Noticed because of a warning emitted by MSVC, this fixees the literal for `kLockedPtr_` to correctly be 64-bits under MSVC, rather than 32-bit.

Fix the size of the enum in FBString.h under MSVC

Summary: MSVC defaults enum sizes to int, so explicitly use `size_t` as the base to have it correctly sized.

Make ProcessReturnCode default-constructible

Summary: We have this previously-unused "NOT STARTED" status, which I recently appropriated to denote moved-out `ProcessReturnCode`s.

It's natural to also use this for default-constructed `ProcessReturnCodes`. Lacking a default constructor leads to a bunch of unnecessarily annoying use of `folly::Optional` in my upcoming diff, so I wanted to get rid of that, see e.g.
