// The base class for all UniFFI Object types.
//
// This class provides core operations for working with the Rust `Arc<T>` pointer to
// the live Rust struct on the other side of the FFI.
//
// There's some subtlety here, because we have to be careful not to operate on a Rust
// struct after it has been dropped, and because we must expose a public API for freeing
// the Kotlin wrapper object in lieu of reliable finalizers. The core requirements are:
//
// * Each `FFIObject` instance holds an opaque pointer to the underlying Rust struct.
// Method calls need to read this pointer from the object's state and pass it in to
// the Rust FFI.
//
// * When an `FFIObject` is no longer needed, its pointer should be passed to a
// special destructor function provided by the Rust FFI, which will drop the
// underlying Rust struct.
//
// * Given an `FFIObject` instance, calling code is expected to call the special
// `destroy` method in order to free it after use, either by calling it explicitly
// or by using a higher-level helper like the `use` method. Failing to do so will
// leak the underlying Rust struct.
//
// * We can't assume that calling code will do the right thing, and must be prepared
// to handle Kotlin method calls executing concurrently with or even after a call to
// `destroy`, and to handle multiple (possibly concurrent!) calls to `destroy`.
//
// * We must never allow Rust code to operate on the underlying Rust struct after
// the destructor has been called, and must never call the destructor more than once.
// Doing so may trigger memory unsafety.
//
// If we try to implement this with mutual exclusion on access to the pointer, there is the
// possibility of a race between a method call and a concurrent call to `destroy`:
//
// * Thread A starts a method call, reads the value of the pointer, but is interrupted
// before it can pass the pointer over the FFI to Rust.
// * Thread B calls `destroy` and frees the underlying Rust struct.
// * Thread A resumes, passing the already-read pointer value to Rust and triggering
// a use-after-free.
//
// One possible solution would be to use a `ReadWriteLock`, with each method call taking
// a read lock (and thus allowed to run concurrently) and the special `destroy` method
// taking a write lock (and thus blocking on live method calls). However, we aim not to
// generate methods with any hidden blocking semantics, and a `destroy` method that might
// block if called incorrectly seems to meet that bar.
//
// So, we achieve our goals by giving each `FFIObject` an associated `AtomicLong` counter to track
// the number of in-flight method calls, and an `AtomicBoolean` flag to indicate whether `destroy`
// has been called. These are updated according to the following rules:
//
// * The initial value of the counter is 1, indicating a live object with no in-flight calls.
// The initial value for the flag is false.
//
// * At the start of each method call, we atomically check the counter.
// If it is 0 then the underlying Rust struct has already been destroyed and the call is aborted.
// If it is nonzero them we atomically increment it by 1 and proceed with the method call.
//
// * At the end of each method call, we atomically decrement and check the counter.
// If it has reached zero then we destroy the underlying Rust struct.
//
// * When `destroy` is called, we atomically flip the flag from false to true.
// If the flag was already true we silently fail.
// Otherwise we atomically decrement and check the counter.
// If it has reached zero then we destroy the underlying Rust struct.
//
// Astute readers may observe that this all sounds very similar to the way that Rust's `Arc<T>` works,
// and indeed it is, with the addition of a flag to guard against multiple calls to `destroy`.
//
// The overall effect is that the underlying Rust struct is destroyed only when `destroy` has been
// called *and* all in-flight method calls have completed, avoiding violating any of the expectations
// of the underlying Rust code.
//
// In the future we may be able to replace some of this with automatic finalization logic, such as using
// the new "Cleaner" functionaility in Java 9. The above scheme has been designed to work even if `destroy` is
// invoked by garbage-collection machinery rather than by calling code (which by the way, it's apparently also
// possible for the JVM to finalize an object while there is an in-flight call to one of its methods [1],
// so there would still be some complexity here).
//
// Sigh...all of this for want of a robust finalization mechanism.
