-/* This file defines dynamic annotations for use with dynamic analysis
- tool such as valgrind, PIN, etc.
-
- Dynamic annotation is a source code annotation that affects
- the generated code (that is, the annotation is not a comment).
- Each such annotation is attached to a particular
- instruction and/or to a particular object (address) in the program.
-
- The annotations that should be used by users are macros in all upper-case
- (e.g., _Py_ANNOTATE_NEW_MEMORY).
-
- Actual implementation of these macros may differ depending on the
- dynamic analysis tool being used.
-
- See http://code.google.com/p/data-race-test/ for more information.
-
- This file supports the following dynamic analysis tools:
- - None (DYNAMIC_ANNOTATIONS_ENABLED is not defined or zero).
- Macros are defined empty.
- - ThreadSanitizer, Helgrind, DRD (DYNAMIC_ANNOTATIONS_ENABLED is 1).
- Macros are defined as calls to non-inlinable empty functions
- that are intercepted by Valgrind. */

- Annotations useful when implementing condition variables such as CondVar,
- using conditional critical sections (Await/LockWhen) and when constructing
- user-defined synchronization mechanisms.
-
- The annotations _Py_ANNOTATE_HAPPENS_BEFORE() and
- _Py_ANNOTATE_HAPPENS_AFTER() can be used to define happens-before arcs in
- user-defined synchronization mechanisms: the race detector will infer an
- arc from the former to the latter when they share the same argument
- pointer.
-
- Example 1 (reference counting):
-
- void Unref() {
- _Py_ANNOTATE_HAPPENS_BEFORE(&refcount_);
- if (AtomicDecrementByOne(&refcount_) == 0) {
- _Py_ANNOTATE_HAPPENS_AFTER(&refcount_);
- delete this;
- }
- }
-
- Example 2 (message queue):
-
- void MyQueue::Put(Type *e) {
- MutexLock lock(&mu_);
- _Py_ANNOTATE_HAPPENS_BEFORE(e);
- PutElementIntoMyQueue(e);
- }
-
- Type *MyQueue::Get() {
- MutexLock lock(&mu_);
- Type *e = GetElementFromMyQueue();
- _Py_ANNOTATE_HAPPENS_AFTER(e);
- return e;
- }
-
- Note: when possible, please use the existing reference counting and message
- queue implementations instead of inventing new ones. */
