+
+// SOME COMMENTS ABOUT USAGE:
+
+// This provides primarily wp<> weak pointer types and RefBase, which work
+// together with sp<> from <StrongPointer.h>.
+
+// sp<> (and wp<>) are a type of smart pointer that use a well defined protocol
+// to operate. As long as the object they are templated with implements that
+// protocol, these smart pointers work. In several places the platform
+// instantiates sp<> with non-RefBase objects; the two are not tied to each
+// other.
+
+// RefBase is such an implementation and it supports strong pointers, weak
+// pointers and some magic features for the binder.
+
+// So, when using RefBase objects, you have the ability to use strong and weak
+// pointers through sp<> and wp<>.
+
+// Normally, when the last strong pointer goes away, the object is destroyed,
+// i.e. it's destructor is called. HOWEVER, parts of its associated memory is not
+// freed until the last weak pointer is released.
+
+// Weak pointers are essentially "safe" pointers. They are always safe to
+// access through promote(). They may return nullptr if the object was
+// destroyed because it ran out of strong pointers. This makes them good candidates
+// for keys in a cache for instance.
+
+// Weak pointers remain valid for comparison purposes even after the underlying
+// object has been destroyed. Even if object A is destroyed and its memory reused
+// for B, A remaining weak pointer to A will not compare equal to one to B.
+// This again makes them attractive for use as keys.
+
+// How is this supposed / intended to be used?
+
+// Our recommendation is to use strong references (sp<>) when there is an
+// ownership relation. e.g. when an object "owns" another one, use a strong
+// ref. And of course use strong refs as arguments of functions (it's extremely
+// rare that a function will take a wp<>).
+
+// Typically a newly allocated object will immediately be used to initialize
+// a strong pointer, which may then be used to construct or assign to other
+// strong and weak pointers.
+
+// Use weak references when there are no ownership relation. e.g. the keys in a
+// cache (you cannot use plain pointers because there is no safe way to acquire
+// a strong reference from a vanilla pointer).
+
+// This implies that two objects should never (or very rarely) have sp<> on
+// each other, because they can't both own each other.
+
+
+// Caveats with reference counting
+
+// Obviously, circular strong references are a big problem; this creates leaks
+// and it's hard to debug -- except it's in fact really easy because RefBase has
+// tons of debugging code for that. It can basically tell you exactly where the
+// leak is.
+
+// Another problem has to do with destructors with side effects. You must
+// assume that the destructor of reference counted objects can be called AT ANY
+// TIME. For instance code as simple as this:
+
+// void setStuff(const sp<Stuff>& stuff) {
+//   std::lock_guard<std::mutex> lock(mMutex);
+//   mStuff = stuff;
+// }
+
+// is very dangerous. This code WILL deadlock one day or another.
+
+// What isn't obvious is that ~Stuff() can be called as a result of the
+// assignment. And it gets called with the lock held. First of all, the lock is
+// protecting mStuff, not ~Stuff(). Secondly, if ~Stuff() uses its own internal
+// mutex, now you have mutex ordering issues.  Even worse, if ~Stuff() is
+// virtual, now you're calling into "user" code (potentially), by that, I mean,
+// code you didn't even write.
+
+// A correct way to write this code is something like:
+
+// void setStuff(const sp<Stuff>& stuff) {
+//   std::unique_lock<std::mutex> lock(mMutex);
+//   sp<Stuff> hold = mStuff;
+//   mStuff = stuff;
+//   lock.unlock();
+// }
+
+// More importantly, reference counted objects should do as little work as
+// possible in their destructor, or at least be mindful that their destructor
+// could be called from very weird and unintended places.
+
+// Other more specific restrictions for wp<> and sp<>:
+
+// Do not construct a strong pointer to "this" in an object's constructor.
+// The onFirstRef() callback would be made on an incompletely constructed
+// object.
+// Construction of a weak pointer to "this" in an object's constructor is also
+// discouraged. But the implementation was recently changed so that, in the
+// absence of extendObjectLifetime() calls, weak pointers no longer impact
+// object lifetime, and hence this no longer risks premature deallocation,
+// and hence usually works correctly.
+
+// Such strong or weak pointers can be safely created in the RefBase onFirstRef()
+// callback.
+
+// Use of wp::unsafe_get() for any purpose other than debugging is almost
+// always wrong.  Unless you somehow know that there is a longer-lived sp<> to
+// the same object, it may well return a pointer to a deallocated object that
+// has since been reallocated for a different purpose. (And if you know there
+// is a longer-lived sp<>, why not use an sp<> directly?) A wp<> should only be
+// dereferenced by using promote().
+
+// Any object inheriting from RefBase should always be destroyed as the result
+// of a reference count decrement, not via any other means.  Such objects
+// should never be stack allocated, or appear directly as data members in other
+// objects. Objects inheriting from RefBase should have their strong reference
+// count incremented as soon as possible after construction. Usually this
+// will be done via construction of an sp<> to the object, but may instead
+// involve other means of calling RefBase::incStrong().
+// Explicitly deleting or otherwise destroying a RefBase object with outstanding
+// wp<> or sp<> pointers to it will result in an abort or heap corruption.
+
+// It is particularly important not to mix sp<> and direct storage management
+// since the sp from raw pointer constructor is implicit. Thus if a RefBase-
+// -derived object of type T is managed without ever incrementing its strong
+// count, and accidentally passed to f(sp<T>), a strong pointer to the object
+// will be temporarily constructed and destroyed, prematurely deallocating the
+// object, and resulting in heap corruption. None of this would be easily
+// visible in the source.
+
+// Extra Features:
+
+// RefBase::extendObjectLifetime() can be used to prevent destruction of the
+// object while there are still weak references. This is really special purpose
+// functionality to support Binder.
+
+// Wp::promote(), implemented via the attemptIncStrong() member function, is
+// used to try to convert a weak pointer back to a strong pointer.  It's the
+// normal way to try to access the fields of an object referenced only through
+// a wp<>.  Binder code also sometimes uses attemptIncStrong() directly.
+
+// RefBase provides a number of additional callbacks for certain reference count
+// events, as well as some debugging facilities.
+
+// Debugging support can be enabled by turning on DEBUG_REFS in RefBase.cpp.
+// Otherwise little checking is provided.
+
+// Thread safety:
+
+// Like std::shared_ptr, sp<> and wp<> allow concurrent accesses to DIFFERENT
+// sp<> and wp<> instances that happen to refer to the same underlying object.
+// They do NOT support concurrent access (where at least one access is a write)
+// to THE SAME sp<> or wp<>.  In effect, their thread-safety properties are
+// exactly like those of T*, NOT atomic<T*>.

-/* Our field elements are represented as nine 32-bit limbs.
- *
- * The value of an felem (field element) is:
- *   x[0] + (x[1] * 2**29) + (x[2] * 2**57) + ... + (x[8] * 2**228)
- *
- * That is, each limb is alternately 29 or 28-bits wide in little-endian
- * order.
- *
- * This means that an felem hits 2**257, rather than 2**256 as we would like. A
- * 28, 29, ... pattern would cause us to hit 2**256, but that causes problems
- * when multiplying as terms end up one bit short of a limb which would require
- * much bit-shifting to correct.
- *
- * Finally, the values stored in an felem are in Montgomery form. So the value
- * |y| is stored as (y*R) mod p, where p is the P-256 prime and R is 2**257.

- *  WARNING WARNING WARNING WARNING
- *
- *  This program runs with CAP_SETUID and CAP_SETGID capabilities on Android
- *  production devices. Be very conservative when modifying it to avoid any
- *  serious security issue. Keep in mind the following:
- *
- *  - This program should only run for the 'root' or 'shell' users
- *
- *  - Avoid anything that is more complex than simple system calls
- *    until the uid/gid has been dropped to that of a normal user
- *    or you are sure to exit.
- *
- *    This avoids depending on environment variables, system properties
- *    and other external factors that may affect the C library in
- *    unpredictable ways.
- *
- *  - Do not trust user input and/or the filesystem whenever possible.
- *
- *  Read README.TXT for more details.
- *
- *
- *
- * The purpose of this program is to run a command as a specific
- * application user-id. Typical usage is:
- *
- *   run-as <package-name> <command> <args>
- *
- *  The 'run-as' binary is installed with CAP_SETUID and CAP_SETGID file
- *  capabilities, but will check the following:
- *
- *  - that it is invoked from the 'shell' or 'root' user (abort otherwise)
- *  - that '<package-name>' is the name of an installed and debuggable package
- *  - that the package's data directory is well-formed (see package.c)
- *
- *  If so, it will drop to the application's user id / group id, cd to the
- *  package's data directory, then run the command there.
- *
- *  NOTE: In the future it might not be possible to cd to the package's data
- *  directory under that package's user id / group id, in which case this
- *  utility will need to be changed accordingly.
- *
- *  This can be useful for a number of different things on production devices:
- *
- *  - Allow application developers to look at their own applicative data
- *    during development.
- *
- *  - Run the 'gdbserver' binary executable to allow native debugging

-/* README
- *
- * What is this?
- *
- * sdcard is a program that uses FUSE to emulate FAT-on-sdcard style
- * directory permissions (all files are given fixed owner, group, and
- * permissions at creation, owner, group, and permissions are not
- * changeable, symlinks and hardlinks are not createable, etc.
- *
- * See usage() for command line options.
- *
- * It must be run as root, but will drop to requested UID/GID as soon as it
- * mounts a filesystem.  It will refuse to run if requested UID/GID are zero.
- *
- * Things I believe to be true:
- *
- * - ops that return a fuse_entry (LOOKUP, MKNOD, MKDIR, LINK, SYMLINK,
- * CREAT) must bump that node's refcount
- * - don't forget that FORGET can forget multiple references (req->nlookup)
- * - if an op that returns a fuse_entry fails writing the reply to the
- * kernel, you must rollback the refcount to reflect the reference the
- * kernel did not actually acquire
- *
- * This daemon can also derive custom filesystem permissions based on directory
- * structure when requested. These custom permissions support several features:
- *
- * - Apps can access their own files in /Android/data/com.example/ without
- * requiring any additional GIDs.
- * - Separate permissions for protecting directories like Pictures and Music.
- * - Multi-user separation on the same physical device.

+// What is this?
+//
+// sdcard is a program that uses FUSE to emulate FAT-on-sdcard style
+// directory permissions (all files are given fixed owner, group, and
+// permissions at creation, owner, group, and permissions are not
+// changeable, symlinks and hardlinks are not createable, etc.
+//
+// See usage() for command line options.
+//
+// It must be run as root, but will drop to requested UID/GID as soon as it
+// mounts a filesystem.  It will refuse to run if requested UID/GID are zero.
+//
+// Things I believe to be true:
+//
+// - ops that return a fuse_entry (LOOKUP, MKNOD, MKDIR, LINK, SYMLINK,
+// CREAT) must bump that node's refcount
+// - don't forget that FORGET can forget multiple references (req->nlookup)
+// - if an op that returns a fuse_entry fails writing the reply to the
+// kernel, you must rollback the refcount to reflect the reference the
+// kernel did not actually acquire
+//
+// This daemon can also derive custom filesystem permissions based on directory
+// structure when requested. These custom permissions support several features:
+//
+// - Apps can access their own files in /Android/data/com.example/ without
+// requiring any additional GIDs.
+// - Separate permissions for protecting directories like Pictures and Music.
+// - Multi-user separation on the same physical device.
