Use a better RNG for Math.random()
https://bugs.webkit.org/show_bug.cgi?id=151641
Reviewed by Anders Carlsson.
Use 64 bits in the random number generator instead of 32 bit. (In
the end, JavaScript, which uses doubles, will only see 52 bits.) This
prevents programs that multiply a random number by a large constant from
seeing non-random "banding" caused by zeroes in the low 20 bits.
I also took the opportunity to upgrade from GameRandom to Xorshift+,
since Xorshift+ passes more benchmarks for randomness, and is not any
slower or more complicated.
Now let us all remember the fateful words of Steve Weibe, who would be
King of Kong: "The randomness went the opposite way that it usually goes."

[GLib] Avoid gint64, std::chrono::microseconds overflows in RunLoop::TimerBase
https://bugs.webkit.org/show_bug.cgi?id=150930
Reviewed by Carlos Garcia Campos.
In RunLoop::TimerBase::start(), avoid overflowing the std::chrono::microseconds
value in case the passed-in fire interval (in seconds) is too large (e.g. when
std::chrono::microseconds::max() is used as the desired interval). This is
achieved by using the passed-in fire interval, converted in microseconds, only
if the value of this interval is smaller than std::chrono::microseconds::max().
In RunLoop::TimerBase::updateReadyTime(), the zero-delay is still considered a
short cut, but we use G_MAXINT64 in case the sum of the current time and the
desired fire interval (now in microseconds) would overflow.

B3/Air should use bubble sort for their insertion sets, because it's faster than std::stable_sort
https://bugs.webkit.org/show_bug.cgi?id=150828
Reviewed by Geoffrey Garen.
Add a pretty good bubble sort implementation to WTF. This implementation has three
common tricks:
- Forward and backward scans. This reduces the severity of certain kinds of bubble sort
pathologies.
- Return if a scan finds the list to be sorted. This gives the algorithm one of its most
attractive properties: it's super fast when the list is already sorted.
- Each scan eliminates one element from future scans. This makes the algorithm no worse
than insertion sort.
Why do we want this? Because bubble sort is a really great stable sort for small lists,
or large lists in which only a handful of elements are out of order. Compiler insertion
sets tend to be one of those or somewhere in between: usually they are very small, and
usually they are sorted. It's rare that an element will be out of order, and when it is,
it's usually very close to where it's supposed to be.
This is a significant speed-up for B3 compile times.

ASCIICType refinements

Reviewed by Geoffrey Garen.
Refined ASCIICType.h by using narrower types. The most valuable part of this
is the part where the result of toASCIIHexValue is uint8_t instead of int;
that's slightly better for RGB values that the compiler needs to know fit
into a byte (coming in some Color work I plan to do soon).
* wtf/ASCIICType.h: Used CharacterType instead of CharType throughout, and
also sorted the using declarations at the bottom of the header.
(WTF::isASCII): Use the name "character" instead of "c".
(WTF::isASCIIAlpha): Ditto. Also use isASCIILower and toASCIILowerUnchecked
instead of writing it out.
(WTF::isASCIIDigit): Ditto.

(WTF::toASCIILowerUnchecked): Tweaked comment.
(WTF::toASCIIUpper): Ditto. Also use isASCIILower instead of writing it out.
(WTF::toASCIIHexValue): Ditto. Also change return type from int to uint8_t.
Also broke a single assertion with && into two separate assertions and got
rid of unnnecessary masking with 0xF0 after shifting left. Also renamed
arguments for the two argument value so they are more sensible.
(WTF::lowerNibbleToASCIIHexDigit): Changed argument type to uint8_t, since
this function does not take a character. Also called it "value" instead of "c".
Also slightly tweaked how the expression is written.
(WTF::upperNibbleToASCIIHexDigit): Ditto. Using the more specific type also
got rid of the need to explicitly mask in this function.
(WTF::isASCIIAlphaCaselessEqual): Renamed the arguments for greater clarity.
With the new clearer argument names, the comment was superfluous.

Dominators should be factored out of the DFG
https://bugs.webkit.org/show_bug.cgi?id=150764
Reviewed by Geoffrey Garen.
This takes what used to be DFGDominators.h/DFGDominators.cpp and turns it into a generic
algorithm that can take any abstract graph. The idea is that you create Dominators<CFG> and
pass it a CFG object, which defines the types of graph nodes and methods for getting
successors, predecessors, etc. The DFG now defines a class called CFG, which is a wrapper for
DFG::Graph that conforms to the thing that wtf/Dominators.h expects.
When doing things to graphs, it's common to refer to the things in the graph as "nodes".
Because I intend to reuse the CFG abstraction with many graph algorithms, that abstraction uses
the term "node" to refer to a DFG basic block. But in Dominators, the method and variable names
still use "block". This is because although Dominators are applicable to any kind of directed
graph, it's super unlikely that we will ever use them for anything but compilers. Indeed, the
only reason why I'm factoring them out of the DFG is so that I can use them with B3 and Air.
This has the nice side effect that a user of WTF::Dominators<JSC::DFG::CFG> will see familiar
terminology like "blocksStrictlyDominatedBy(...)" instead of "nodesStrictlyDominatedBy(...)",
which would be super confusing.
Overall, wtf/Dominators.h is a combination of what used to be in DFGDominators.h,
DFGDominators.cpp, DFGNaiveDominators.h, and DFGNaiveDominators.cpp. I only changed code when I
had to in order to make it generic.

Add a fast path to WTF's operator+ magic for concatenation of two strings where
one of them is empty. In that case, try to avoid allocation altogether by returning
the non-empty string.
Spotted this while analyzing memory peaks during page load; it turns out we were
duplicating whole text resources (JS, CSS) at the end of decoding, below
TextResourceDecoder::decodeAndFlush(). That function effectively does:
return decode() + flush();
Very often, flush() returns an empty string, so due to the naive operator+,
we'd allocate a new StringImpl of length (decode().length() + flush().length())
and copy the return value from decode() into it. So silly!
Had to make the tryMakeString() machinery use String as a return type instead of
RefPtr<StringImpl> to make all the right overloads gel. StringTypeAdapter templates
are now required to provide a toString() function.

Reviewed by Geoffrey Garen.
This adds two major things to WTF: WeakRandom and ParallelHelperPool. WeakRandom was
already in JSC; we're just hoisting it into WTF. It's just a weak random number generator
that's suitable for places where you need just a tiny bit of randomness.
ParallelHelperPool is a new API that simplifies data-parallel algorithms like the JSC GC.
In a data-parallel algorithm, we want to run one task on as many cores as possible and let
the task worry about which subset of the input data to work on. In some cases, the
algorithm will not need to do any load balancing - and if load balancing is required, it's
up to the user. This is appropriate in contexts where the load balancing needs to be
custom-tuned for performance, like the GC's marking phase.
This new API has three concepts: task, client, and pool. A task is a reference counted
object with a run() method, which may be run in parallel. It is usually used to wrap a
functor. A pool is a pool of threads that can run things. A client is a placeholder for a
task. A client can have zero or one tasks. A client must be registered with a pool. When a
client has a task, the pool's threads may choose to run it. If a thread starts running a
task, it will run it to completion. When the task returns on any thread, the client takes
it to mean that the task should be removed. That means that any currently running instances
of the task will finish but no new threads will attempt to run the task. You can easily ask
a client to wait until a task finishes. You can also easily ask a client to run a task on
the current thread in addition to possibly some helper threads from the pool.
For some data-parallel algorithms, programming with ParallelHelperPool is as easy as:
client.runFunctionInParallel(
[=] () {
do things;
});
Note that you cannot tell ahead of time how many threads will join to help the task.
Threads may become available after the task has already started running. Those threads may
join after the other threads have already started. It's not advisable to make algorithmic
decisions based on client.numberOfActiveThreads(), since that number may change. Usually
the best way to use ParallelHelperPool is with an algorithm that has its own custom
worklist. An example of a very simple custom worklist is the one in the JSC GC's copying
phase - it's just a Vector and an index that indicates the next set of elements to process.
This new API was initially designed to simplify how GCThread works, by replacing Phase with
a callback that contains the phase's workload. I then realized that with a few tweaks, I
could make this somewhat general enough that it might become interesting outside GC. I also
realized that I could use this to enable thread sharing. So, although the API is kinda
quirky, it's grounded in the reality of how the JSC GC does parallelism.

This change makes notifyOne()/notifyAll() blazing fast when nobody is waiting, by using the
various hooks that ParkingLot gives us to maintain a m_hasWaiters variable. When it's false, it
means that any unpark operation would simply return immediately.
This is a 45% speed-up for the 1-producer/1-consumer scenario with a 100-element queue when you
use the notifyOne()-per-enqueue style. What's cool about this change is that you can now safely
call notifyOne() (or notifyAll()) out of paranoia, just in case someone might be waiting. It's
free to do so if nobody is waiting!

Replace all remaining uses of WTF::Mutex with WTF::Lock
https://bugs.webkit.org/show_bug.cgi?id=148089
Reviewed by Geoffrey Garen.
This also beefs up and rationalizes the Condition API, so that it can deal with units of time
other than just steady_clock. This makes it easier to port ThreadCondition and
std::condition_variable code over to Condition. This patch does not take a position on what
kind of time is best; from reading a lot of the uses in WebCore, it seems like our use of
double to measure seconds is often nicer than the many different classes in std::chrono.
Also added a Condition speed test, to make sure that all of this is a good idea. And indeed it
is. The 1-producer/1-consumer scenario with a 100-element queue runs 36x faster using
Lock/Condition than Mutex/ThreadCondition when you use the notifyOne()-per-enqueue style. It
runs 58x faster with Lock/Condition when you use the notifyAll()-at-boundary style. Note that
I have a bug open for making the notifyOne()-per-enqueue style even faster:
https://bugs.webkit.org/show_bug.cgi?id=148090. Also, the 10-consumer/10-producer scenario with
a 100-element queue runs 20x faster with Lock/Condition for notifyOne()-per-enqueue and 30x
faster with notifyAll()-at-boundary. The only way to tweak the test to get
Mutex/ThreadCondition to win is to have one producer, one consumer, a 1-element queue, and use
the notifyOne()-per-enqueue style. In that case, one of the two threads is going to be waiting
most of the time and the test basically measures wake-up latency and nothing else. Because
Condition::wait() does a little bit more work than ThreadCondition::wait(),
Mutex/ThreadCondition end up running 3% faster in this test case. But if you vary any of the
parameters of the test, Mutex/ThreadCondition ends up losing - all it takes is more threads or
a queue size of 5 or more. To my knowledge, we never do producer/consumer with a queue bounded
to one element precisely because that approach is the least efficient regardless of locking
algorithm. For example, neither WTF::MessageQueue nor DFG::Worklist have any bounds on their
queue size. So, it seems that replacing all uses of system mutexes and condition variables with
our own thing is a great idea.

WTF should have a compact Condition object to use with Lock
https://bugs.webkit.org/show_bug.cgi?id=147986
Reviewed by Geoffrey Garen.
Adds a condition variable implementation based on ParkingLot, called simply WTF::Condition.
It can be used with WTF::Lock or actually any lock implementation. It should even work with
WTF::SpinLock, WTF::Mutex, or std::mutex. Best of all, Condition only requires one byte.
ParkingLot almost contained all of the functionality needed to implemenet wait/notify. We
could have implemented Condition using a 32-bit (or even 64-bit) version that protects
against a notify that happens just before we park. But, this changes the ParkingLot API to
give us the ability to run some code between when ParkingLot enqueues the current thread
and when it actually sleeps. This callback is called with no locks held, so it can call
unlock() on any kind of lock, so long as that lock's unlock() method doesn't recurse into
ParkingLot::parkConditionally(). That seems unlikely; unlock() is more likely to call
ParkingLot::unparkOne() or unparkAll(). WTF::Lock will never call parkConditionally()
inside unlock(), so WTF::Lock is definitely appropriate for use with Condition.
Condition supports most of the API that std::condition_variable supports. It does some
things to try to reduce footgun potential. The preferred timeout form is waitUntil() which
takes an absolute time from the steady_clock. The only relative timeout form also takes a
predicate callback, so it's impossible to write the subtly incorrect
"while (...) wait_for(...)" idiom.
This patch doesn't actually introduce any uses of WTF::Condition other than the unit tests.
I'll start switching code over to using WTF::Condition in another patch.

WTF::Lock should not suffer from the thundering herd
https://bugs.webkit.org/show_bug.cgi?id=147947
Reviewed by Geoffrey Garen.
This changes Lock::unlockSlow() to use unparkOne() instead of unparkAll(). The problem with
doing this is that it's not obvious after calling unparkOne() if there are any other threads
that are still parked on the lock's queue. If we assume that there are and leave the
hasParkedBit set, then future calls to unlock() will take the slow path. We don't want that
if there aren't actually any threads parked. On the other hand, if we assume that there
aren't any threads parked and clear the hasParkedBit, then if there actually were some
threads parked, then they may never be awoken since future calls to unlock() won't take slow
path and so won't call unparkOne(). In other words, we need a way to be very precise about
when we clear the hasParkedBit and we need to do it in a race-free way: it can't be the case
that we clear the bit just as some thread gets parked on the queue.
A similar problem arises in futexes, and one of the solutions is to have a thread that
acquires a lock after parking sets the hasParkedBit. This is what Rusty Russel's usersem
does. It's a subtle algorithm. Also, it means that if a thread barges in before the unparked
thread runs, then that barging thread will not know that there are threads parked. This
could increase the severity of barging.
Since ParkingLot is a user-level API, we don't have to worry about the kernel-user security
issues and so we can expose callbacks while ParkingLot is holding its internal locks. This
change does exactly that for unparkOne(). The new variant of unparkOne() will call a user
function while the queue from which we are unparking is locked. The callback is told basic
stats about the queue: did we unpark a thread this time, and could there be more threads to
unpark in the future. The callback runs while it's impossible for the queue state to change,
since the ParkingLot's internal locks for the queue is held. This means that
Lock::unlockSlow() can either clear, or leave, the hasParkedBit while releasing the lock
inside the callback from unparkOne(). This takes care of the thundering herd problem while
also reducing the greed that arises from barging threads.
This required some careful reworking of the ParkingLot algorithm. The first thing I noticed
was that the ThreadData::shouldPark flag was useless, since it's set exactly when
ThreadData::address is non-null. Then I had to make sure that dequeue() could lazily create
both hashtables and buckets, since the "callback is called while queue is locked" invariant
requires that we didn't exit early due to the hashtable or bucket not being present. Note
that all of this is done in such a way that the old unparkOne() and unparkAll() don't have
to create any buckets, though they now may create the hashtable. We don't care as much about
the hashtable being created by unpark since it's just such an unlikely scenario and it would
only happen once.
This change reduces the kernel CPU usage of WTF::Lock for the long critical section test by
about 8x and makes it always perform as well as WTF::WordLock and WTF::Mutex for that
benchmark.

Always use a byte-sized lock implementation
https://bugs.webkit.org/show_bug.cgi?id=147908
Reviewed by Geoffrey Garen.
At the start of my locking algorithm crusade, I implemented Lock, which is a sizeof(void*)
lock implementation with some nice theoretical properties and good performance. Then I added
the ParkingLot abstraction and ByteLock. ParkingLot uses Lock in its implementation.
ByteLock uses ParkingLot to create a sizeof(char) lock implementation that performs like
Lock.
It turns out that ByteLock is always at least as good as Lock, and sometimes a lot better:
it requires 8x less memory on 64-bit systems. It's hard to construct a benchmark where
ByteLock is significantly slower than Lock, and when you do construct such a benchmark,
tweaking it a bit can also create a scenario where ByteLock is significantly faster than
Lock.
So, the thing that we call "Lock" should really use ByteLock's algorithm, since it is more
compact and just as fast. That's what this patch does.
But we still need to keep the old Lock algorithm, because it's used to implement ParkingLot,
which in turn is used to implement ByteLock. So this patch does this transformation:
- Move the algorithm in Lock into files called WordLock.h|cpp. Make ParkingLot use
WordLock.
- Move the algorithm in ByteLock into Lock.h|cpp. Make everyone who used ByteLock use Lock
instead. All other users of Lock now get the byte-sized lock implementation.
- Remove the old ByteLock files.

WTF should have a ParkingLot for parking sleeping threads, so that locks can fit in 1.6 bits
https://bugs.webkit.org/show_bug.cgi?id=147665
Reviewed by Mark Lam.
This change adds a major new abstraction for concurrency algorithms in WebKit. It's called a
ParkingLot, and it makes available a thread parking queue for each virtual address in memory.
The queues are maintained by a data-access-parallel concurrent hashtable implementation. The
memory usage is bounded at around half a KB per thread.
The ParkingLot makes it easy to turn any spinlock-based concurrency protocol into one that
parks threads after a while. Because queue state management is up to the ParkingLot and not
the user's data structure, this patch uses it to implement a full adaptive mutex in one byte.
In fact, only three states of that byte are used (0 = available, 1 = locked, 2 = locked and
there are parked threads). Hence the joke that ParkingLot allows locks that fit in 1.6 bits.
ByteLock is used as a replacement for ByteSpinLock in JavaScriptCore.
The API tests for this also demo how to create a completely fair (FIFO) binary semamphore. The
comment in Lock.h shows how we could accelerate Lock performance using ParkingLot. After we
are sure that this code works, we can expand the use of ParkingLot. That's covered by

Lightweight locks should be adaptive
https://bugs.webkit.org/show_bug.cgi?id=147545
Reviewed by Geoffrey Garen.
A common idiom in WebKit is to use spinlocks. We use them because the lock acquisition
overhead is lower than system locks and because they take dramatically less space than system
locks. The speed and space advantages of spinlocks can be astonishing: an uncontended spinlock
acquire is up to 10x faster and under microcontention - short critical section with two or
more threads taking turns - spinlocks are up to 100x faster. Spinlocks take only 1 byte or 4
bytes depending on the flavor, while system locks take 64 bytes or more. Clearly, WebKit
should continue to avoid system locks - they are just far too slow and far too big.
But there is a problem with this idiom. System lock implementations will sleep a thread when
it attempts to acquire a lock that is held, while spinlocks will cause the thread to burn CPU.
In WebKit spinlocks, the thread will repeatedly call sched_yield(). This is awesome for
microcontention, but awful when the lock will not be released for a while. In fact, when
critical sections take tens of microseconds or more, the CPU time cost of our spinlocks is
almost 100x more than the CPU time cost of a system lock. This case doesn't arise too
frequently in our current uses of spinlocks, but that's probably because right now there are
places where we make a conscious decision to use system locks - even though they use more
memory and are slower - because we don't want to waste CPU cycles when a thread has to wait a
while to acquire the lock.
The solution is to just implement a modern adaptive mutex in WTF. Luckily, this isn't a new
concept. This patch implements a mutex that is reminiscent of the kinds of low-overhead locks
that JVMs use. The actual implementation here is inspired by some of the ideas from [1]. The
idea is simple: the fast path is an inlined CAS to immediately acquire a lock that isn't held,
the slow path tries some number of spins to acquire the lock, and if that fails, the thread is
put on a queue and put to sleep. The queue is made up of statically allocated thread nodes and
the lock itself is a tagged pointer: either it is just bits telling us the complete lock state
(not held or held) or it is a pointer to the head of a queue of threads waiting to acquire the
lock. This approach gives WTF::Lock three different levels of adaptation: an inlined fast path
if the lock is not contended, a short burst of spinning for microcontention, and a full-blown
queue for critical sections that are held for a long time.
On a locking microbenchmark, this new Lock exhibits the following performance
characteristics:
- Lock+unlock on an uncontended no-op critical section: 2x slower than SpinLock and 3x faster
than a system mutex.
- Lock+unlock on a contended no-op critical section: 2x slower than SpinLock and 100x faster
than a system mutex.
- CPU time spent in lock() on a lock held for a while: same as system mutex, 90x less than a
SpinLock.
- Memory usage: sizeof(void*), so on 64-bit it's 8x less than a system mutex but 2x worse than
a SpinLock.
This patch replaces all uses of SpinLock with Lock, since our critical sections are not
no-ops so if you do basically anything in your critical section, the Lock overhead will be
invisible. Also, in all places where we used SpinLock, we could tolerate 8 bytes of overhead
instead of 4. Performance benchmarking using JSC macrobenchmarks shows no difference, which is
as it should be: the purpose of this change is to reduce CPU time wasted, not wallclock time.
This patch doesn't replace any uses of ByteSpinLock, since we expect that the space benefits
of having a lock that just uses a byte are still better than the CPU wastage benefits of
Lock. But, this work will enable some future work to create locks that will fit in just 1.6
bits: https://bugs.webkit.org/show_bug.cgi?id=147665.
Rolling this back in after fixing Lock::unlockSlow() for architectures that have a truly weak
CAS. Since the Lock::unlock() fast path can go to slow path spuriously, it may go there even if
there aren't any threads on the Lock's queue. So, unlockSlow() must be able to deal with the
possibility of a null queue head.

[WTF] Turn tryMakeString(), makeString() into variadic templates
https://bugs.webkit.org/show_bug.cgi?id=147142
Reviewed by Sam Weinig.
Built upon the original work by Anders Carlsson, Mark Rowe and Sam Weinig.
Implement tryMakeString() and makeString() as variadic templates, replacing
the argument count-based overloads.
tryMakeString() now constructs a stack-based tuple of necessary StringTypeAdapter
objects and utilizes the StringAdapterTuple struct template to operate on that
tuple, recursively calling the necessary operations on each element in the tuple.
This effectively mimics the process of previous tryMakeString() implementation,
but makes it scalable to a tuple of elements that are to be concatenated.
StringAppend class template now stores two StringTypeAdapter objects for the
two passed-in string objects, packed in a tuple, calling
StringAdapterTuple<>::createString() directly when concatenating the two objects
into one String.

Previously, when copying a HashTable, we would start from scratch

With this patch, we have 2 improvements to remove most of the cost.
First, we compute a good size from the start. This removes all the
reallocations and rehashs.
This is where the biggest gain comes from.
The second part is a simpler version of add() when we know that
we cannot find a bucket with the same key and there cannot
be any deleted bucket.

CheckedArithmetic's operator bool() and operator==() is broken.
https://bugs.webkit.org/show_bug.cgi?id=146129
Reviewed by Geoffrey Garen and Oliver Hunt.
The existing operator UnspecifiedBoolType*() in CheckedArithmetic is erroneously
allowing the Checked value to be implicitly casted into pointer types. This is
because it is doing a reinterpret_cast<UnspecifiedBoolType*>(1) whereas the idiom
relies on the address of a member e.g. &Checked::m_value. As a result,
ImageBufferData::putData() was getting an implicit cast of a Checked value to
(void*)1 and doing incorrect pointer comparisons on it.
Also, 2 of CheckedArithmetic's operator==() will crash if used on an overflowed
value, while a 3rd one does not. The 3rd one should be consistent and also crash
if used on an overflowed Checked value.
In this fix, we replace operator UnspecifiedBoolType*() with an explicit operator
bool(). We also add the missing operators <, <=, >, and >=. That takes care of
the comparisons in ImageBufferData::putData().

We were wasting sizeof(Vector) on every segment in SegmentVector.
The segments were using inline capacity, and would never go beyond it,
so all the size/capacity/out-of-line-buffer metadata was useless.
Change the internal representation to Vector<T[SegmentSize]> instead.
This saves 16 bytes per segment, so lower SegmentSize -> bigger savings!

Introduce UniquedStringImpl and SymbolImpl to separate symbolic strings from AtomicStringImpl
https://bugs.webkit.org/show_bug.cgi?id=144848
Reviewed by Darin Adler.
he current AtomicStringImpl accidentally means the symbol OR atomic StringImpl.
t's not correct to its name and it's error prone.
In this patch, we'll introduce/changes classes into WTF.
1. UniquedStringImpl
It's derived class from StringImpl. And it represents symbol || atomic StringImpl.
2. SymbolImpl
It's derived class from UniquedStringImpl. Only symbol strings can become this.
It ensures the given StringImpl is symbol in compile time.
3. AtomicStringImpl
It's derived class from UniquedStringImpl. Only atomic (non-normal && non-symbol) strings can become this.
It ensures the given StringImpl is atomic in compile time.
And, in this time, I just accept UniqueStringImpl in AtomicString. As the result,
1. Now AtomicStringImpl issue is fixed. Its SymbolImpl is separated and UniquedStringImpl is introduced.
2. But AtomicString still have both symbol and atomic strings.
This should be solved in the separated patch.

Ensure that all the smart pointer types in WTF clear their pointer before deref
https://bugs.webkit.org/show_bug.cgi?id=143789
Reviewed by Ryosuke Niwa.
In order to prevent use after free bugs caused by destructors
that end up trying to access the smart pointer itself, we should
make sure we always clear the m_ptr field before calling deref.
Essentially the UaF path is:
struct Foo : RefCounted<Foo> {
Wibble* m_wibble;
void doSomething();
~Foo() { m_wibble->doSomethingLikeCleanup(); }
};
struct Wibble {
void doSomethingLikeCleanup()
{
if (m_foo) {
/* if this branch is not here we get a null deref */
m_foo->doSomething();
}
}
void replaceFoo(Foo* foo) { m_foo = foo; }
RefPtr<Foo> m_foo;
};
Wibble* someWibble = /* a Wibble with m_foo->m_refCount == 1 */;
/* and m_foo points to someWibble */;
someWibble->replaceFoo(someOtherFoo);
+ someWibble->m_foo->m_ptr->deref();
+ someWibble->m_foo->m_ptr->~Foo()
+ someWibble->m_foo->m_ptr->m_wibble->doSomethingLikeCleanup()
+ someWibble->m_foo->m_ptr->m_wibble /* someWibble */ ->m_foo->m_ptr /*logically dead*/ ->doSomething()
By clearing m_ptr first we either force a null pointer deref or
we force our code down a path that does not use the dead smart
pointer.

Do not keep a reference of the WorkQueue for the entire life of
its worker thread, since every task scheduled on the WorkQueue
already takes a reference. Instead, take a reference of the main
loop to make sure that when the worker thread starts, the main
loop hasn't been released to avoid runtime warnings (see
webkit.org/b/140998). Also removed the g_main_context_pop_thread_default()
from the thread body, since the thread-specific context queue will
be freed anyway when the thread exits.
If the WorkQueue is released early, before the thread has started,
schedule a main loop quit in the context, to make sure it will
be the first thing run by the main loop and the thread will exit.

JSON.stringify() to implement efficient appending of strings while escaping
quotes, control characters and \uNNNN-style characters.
The main benefit comes from only doing a single buffer expansion up front,
instead of doing it every time we append something. The fudge factor is pretty
large, since the maximum number of output characters per input character is 6.
The first landing of this patch had two bugs in it:
- Made \uNNNN escapes uppercase hexadecimal instead of lowercase.
- Didn't preallocate enough space for 8-bit input strings.
Both were caught by existing tests on our bots, and both were due to last-minute
changes before landing. :/

While AtomicStringTable (in WebCore case) exists in thread local storage,
SymbolRegistry exists per VM and StringImpl* has a reference to the registered SymbolRegistry.
Since StringImpl has isSymbol etc. members, it's class is aware of Symbol use cases.
So introduce SymbolRegistry in WTF layers as if AtomicStringTable.

It always succeeds because a symbol (non empty) string

Replace TCSpinLock with a new WTF::SpinLock based on WTF::Atomic.
<https://webkit.org/b/142674>
Reviewed by Filip Pizlo.
We no longer use TCMalloc in our code, and we now have C++11. This replaces the
TCMalloc_SpinLock with a new WTF::SpinLock based on WTF::Atomic (which is a
wrapper around std::atomic).
Note that there is a StaticSpinLock and a SpinLock:
1. StaticSpinLock is an alias for SpinLockBase, and its initialization relies on
static / global std:atomic being automatically initialized to 0 at compile time.
Hence, StaticSpinLock should only be used for statics / globals (including
static members of classes / structs).
2. SpinLock is derived from SpinLockBase, and adds a default constructor to
initialize its internal atomic value to 0. Because SpinLock has a constructor,
it cannot be used for statics / globals. Objects that want to embed a spin
lock as an instance field should use SpinLock so that it is initialized properly.
std::atomic will not automatically initialize instance fields to 0. Hence,
StaticSpinLock will not work correctly as instance fields of a class / struct.

The CAS functions provided by std::atomic takes a reference to the expected

provide a WTF::Atomic struct that wraps std::atomic, and provide CAS
methods that won't alter the expected value if the CAS fails.
The method names in WTF::Atomic are chosen to be identical to those
in std::atomic so that WTF::Atomic can be a simple drop in replacement

8-bit version of weakCompareAndSwap() can cause an infinite loop.
https://webkit.org/b/142513>
Reviewed by Filip Pizlo.
Presently, Bitmap::concurrentTestAndSet() uses the 8-bit version of
weakCompareAndSwap() (which compares and swaps an uint8_t value).
Bitmap::concurrentTestAndSet() has a loop that checks if a bit in the
byte of interest has been set. If not, it will call the 8-bit CAS
function to set the bit.
Under the covers, for ARM, the 8-bit CAS function actually works with a
32-bit CAS. The 8-bit CAS will first fetch the 32-bit value in memory
that should contain the 8-bit value, and check if it contains the
expected byte. If the value in memory doesn't have the expected byte,
it will return early to its caller. The expectation is that the caller
will reload the byte from memory and call the 8-bit CAS again.
Unfortunately, this code path that returns early does not have a
compiler fence. Without a compiler fence, the C++ compiler can
optimize away the reloading of the expected byte value, leaving it
unchanged. As a result, we'll have a infinite loop here that checks a
value that will never change, and the loop will not terminate until the
value changes.
The fix is to eliminate the early return check in the 8-bit CAS, and
have it always call down to the 32-bit CAS. The 32-bit CAS has a
compiler fence which will prevent this issue.

Regression(r173761): ASSERTION FAILED: !is8Bit() in StringImpl::characters16()

Reviewed by Michael Saboff and Benjamin Poulain.
Fix ASSERTION FAILED: !is8Bit() in StringImpl::characters16() from
WTF::equalInner() after r173761. The code was incorrectly assuming that
if stringImpl is 16-bit, then matchString is 16-bit too, which is not
correct.
Also rename WTFString::startsWith() / endsWith() taking an offset to
hasInfixStartingAt() / hasInfixEndingAt() for clarity. It seems odd
to call it startsWith even though it won't technically *start* with
the pattern if the input offset is greater than zero.
Also drop the caseSensitive argument as it is never used (always true

WeakPtr functions crash when created with default constructor
https://bugs.webkit.org/show_bug.cgi?id=140479
Reviewed by Andreas Kling.
This patch rearranges how WeakPtr works, and has the following ideas behind it:
1. WeakPtr should use Ref internally. This solves the crash by always having a
valid WeakReference.
2. Clients should not be able to construct WeakReferences directly. Instead,
only WeakPtrFactory (and WeakPtr's default constructor) should be able to
construct them. They are considered an implementation detail of WeakPtr.
3. Except for the default constructor, clients should not be able to construct
WeakPtrs directly. Instead, the WeakPtrFactory must construct them. This
guarantees that the WeakPtrs all reference the same WeakReference.
4. Clients can construct a WeakPtr using its default constructor, and then
use the assignment operator to make it non-null. (Or they could use
WeakPtrFactory to make it non-null at creation-time.)
5. No one was using WeakReference::bindTo(), and it doesn't seem useful, so I
removed it.

RefPtr does). These constructors/operators are relied upon in various places

Add strong typing to RefCounter interface, return value as a bool.
https://bugs.webkit.org/show_bug.cgi?id=139776
Reviewed by Geoff Garen.
Currently all token vended by a RefCounter have the same type - Ref<RefCounter::Count>.
This means there is no compile time type checking to prevent mistakes. Update the count()
method to token<>(), templated on type used to identify the token being returned.
Calls to token<T>() will return a result of type RefCounter::Token<T>.
There are a few problems with the fact the counter will return you an exact count of the
number of outstanding tokens:
- It is desirable to only fire the callback on zero-edge changes; it is more consistent
to do so if the value is only readable as a boolean.
- It is desirable to provide the value as an argument to the callback, however to make
this useful for integer values it is also necessary to indicate the direction of change
(0->1 is often interesting where 2->1 is not).
- There is a mismatch between the precision of returning a count, and the inherent
imprecision of a token based mechanism, where it may be difficult to guarantee
absolutely no unnecessary refcount churn, and thus unintentional counter values.

Make sure range based iteration of Vector<> still receives bounds checking
https://bugs.webkit.org/show_bug.cgi?id=138821
Reviewed by Mark Lam.
Add a new IndexedIterator struct to WTF that wraps a
Vector type and index to provide pointer like semantics
while still performing runtime bounds checking, even in
release builds. We store a simple index into the vector
which means that this iterator allows vector resizing
during iteration. If the vector is resized such that the
iterator is out of bounds, then any attempt to dereference
the iterator will crash safely.
For the purpose of retaining semantically equivalent
behaviour, the iterator can be moved to m_index == size()
as that is the standard "end" terminator for these types.
Attempting to dereference at that point will still crash
rather than perform an unsafe memory operation.
By necessity there are many overrides for operator + and - as
we otherwise hit many different type promotion ambiguities when
performing arithmetic with iterators. These ambiguities are also
different for 32- vs. 64-bit, so duplicating the functions
and then forwarding to the core implementations that performed
the bounds checking and mutation seemed like the right call.

Replace PassRef with Ref/Ref&& across the board.
<https://webkit.org/b/139587>
Reviewed by Darin Adler.
Kill the PassRef class and replace it by Ref/Ref&&.
Usage is simple:
- For locals and members, keep using Ref<T>.
- For return types, use Ref<T>.
- For (ownership-transferring) arguments, use Ref<T>&&.
When passing to a Ref&&, use WTF::move() to mobilize the value
at the call site, e.g:
void myFunction(Ref<Foo>&&);
Ref<Foo> myFoo(Foo::create());
myFunction(WTF::move(myFoo));
// 'myFoo' is invalid from this point forward.
As you can see, it works a lot like PassRefPtr, but unlike PassRefPtr
it won't surprise you by becoming null *unless* you WTF::move it.
I've also added a Ref::copyRef() for instances where you want to
return a Ref *without* transferring ownership, e.g code like:
Ref<Foo> foo() { return m_foo; }
... now becomes ...
Ref<Foo> foo() { return m_foo.copyRef(); }
This makes it explicit that a refcount bump will occur.
Finally, do note that unlike last year's PassRef, Ref&& does not
require you to move it to avoid leaking; it will clean itself up.

Generalize PageActivityAssertionToken
https://bugs.webkit.org/show_bug.cgi?id=139106
Reviewed by Sam Weinig.
PageActivityAssertionToken is a RAII mechanism implementing a counter, used by PageThrottler
to count user visible activity in progress on the page (currently page load and media playback).
Use of an RAII type is prevents a number of possible errors, including double counting a single
media element, or failing to decrement the count after a media element has been deallocated.
The current implementation has a number of drawbacks that have been addressed by this refactoring:
- specific to single use in PageThrottler class - not reusable.
- incomplete encapsulation - the counter and WeakPtrFactory that comprise the current implementation
are not encapsulated (are in the client type, PageThrottler).
- tokens are not shared - PageActivityAssertionToken instances are managed by std::unique, every
increment requires an object allocation.
- redundancy - the current implementation uses a WeakPtr to safely reference the PageThrottler, this
is internally implemented using a reference counted type, resulting in two counters being
incremented (one in the PageActivityAssertionToken, one in the PageThrottler).
In the reimplementation:
- a callback is provided via a lambda function, which allows for easy reuse without a lot of
boilerplate code.
- the counter, callback and ownership of the otherwise weakly-owned token is encapsulated within the
RefCounter type.
- a single count within RefCounter::Count stores the counter value, and also manage the lifetime
of this object.
- standard RefPtrs are used to manage references to the RefCounter::Count.

Make sure range based iteration of Vector<> still receives bounds checking
https://bugs.webkit.org/show_bug.cgi?id=138821
Reviewed by Mark Lam.
Add a new IndexedIterator struct to WTF that wraps a
Vector type and index to provide pointer like semantics
while still performing runtime bounds checking, even in
release builds. We store a simple index into the vector
which means that this iterator allows vector resizing
during iteration. If the vector is resized such that the
iterator is out of bounds, then any attempt to dereference
the iterator will crash safely. Any other errors, including
overflows, and over extending the iterator will likewise
crash.
For the purpose of retaining semantically equivalent
behaviour, the iterator can be moved to m_index == size()
as that is the standard "end" terminator for these types.
Attempting to dereference at that point will still crash
rather than perform an unsafe memory operation.
In order to maintain the validity of all the bounds checking,
we perform full integer range checking prior to any mutation
of the iterator location. If we detect an arithmetic overflow
we will crash rather than attempting to carry on.
By necessity there are many overrides for operator + and - as
we otherwise hit many different type promotion ambiguities when
performing arithmetic with iterators. These ambiguities are also
different for 32- vs. 64-bit, so duplicating the functions
and then forwarding to the core implementations that performed
the bounds checking and mutation seemed like the right call.

Add a more correct way to compare floating point numbers and use it
https://bugs.webkit.org/show_bug.cgi?id=138527
Reviewed by Darin Adler.
To compare floating point numbers in the code base, we would often rely
on the following check:
std::abs(a - b) <= std::numeric_limits<T>::epsilon()
However, this is not correct for arbitrary floating point values, and
will fail for values that are not close to zero.
This patch introduces a WTF::areEssentiallyEqual() templated function
that can only be called with floating point types and relies on the
following formula from [1][2] that defines u as being "essentially
equal" to v if: | u - v | / |u| <= e and | u - v | / |v| <= e

By definition of calculateLocalTimeOffset, input time should be UTC time.
But there are many cases when input time is based on local time.
So, it gives erroneous results while calculating offset of DST boundary time.

Added. This adopt function is slightly different than both adoptCF and adoptNS,
in that unlike adoptCF(), it can be passed an Objective-C type (since OS objects
are sometimes Objective-C objects, but not always), and unlike adoptNS() it doesn't
require us to jump through hoops to appease GC (since OS objects are not Objective-C
objects if GC is enabled).

Allow DOM methods to return references instead of pointers
https://bugs.webkit.org/show_bug.cgi?id=136931
Add support for having WTF::getPtr() transform reference arguments
into raw pointers so that DOM methods can now return references when
appropriate and so that the generated bindings code can handle this
via WTF::getPtr().
This patch had to alter the way getPtr() was overloaded for smart
pointer types so that we don't call &p on smart pointers but p.get().
This was needed because the new WTF::getPtr(T&) was being called for
RefPtr<T> arguments instead of the getPtr(const RefPtr<T>&) overload.
This was addressed using traits and template specialization to
distinguish WTF smart pointers from other types.

GMainLoopSource is exposed to race conditions
https://bugs.webkit.org/show_bug.cgi?id=135800
Reviewed by Carlos Garcia Campos.
GMainLoopSource objects can be dispatching tasks on one thread
while having a new task scheduled on a different thread. This
can for instance occur in WebKitVideoSink, where the timeout
callback can be called on main thread while at the same time
it is being rescheduled on a different thread (created through
GStreamer).
The initial solution is to use GMutex to prevent parallel data
access from different threads. In the future I plan to look at
the possibility of creating thread-specific GMainLoopSource
objects that wouldn't require the use of GMutex.
GSource, GCancellable and std::function<> objects are now packed
into an internal Context structure. Using the C++11 move semantics
it's simple to, at the time of dispatch, move the current context
out of the GMainLoopSource object in case the dispatch causes a
rescheduling on that same object.
Also added in the Context struct is a new GCancellable. The pointer
of that object is shared with the GMainLoopSource before the Context
is moved out for the callback dispatch. This makes it safe to cancel
or even delete the GMainLoopSource during the dispatch and prevents
use-after-delete on GMainLoopSource once the dispatch is done in
the GMainLoopSource::*Callback() methods.
All the schedule*() methods and the cancelWithoutLocking() method
callers now lock the GMutex to ensure no one else is accessing the
data at that moment. Similar goes for the dispatch methods, but those
do the dispatch and possible destruction duties with the mutex unlocked.
The dispatch can cause rescheduling on the same GMainLoopSource object,
which must not be done with a locked mutex.

Disk image cache code unnecessarily complicates SharedBuffer implementation. We can remove

GMainLoopSource is exposed to race conditions
https://bugs.webkit.org/show_bug.cgi?id=135800
Reviewed by Carlos Garcia Campos.
GMainLoopSource objects can be dispatching tasks on one thread
while having a new task scheduled on a different thread. This
can for instance occur in WebKitVideoSink, where the timeout
callback can be called on main thread while at the same time
it is being rescheduled on a different thread (created through
GStreamer).
The initial solution is to use GMutex to prevent parallel data
access from different threads. In the future I plan to add better
assertions, some meaningful comments and look at the possibility
of creating thread-specific GMainLoopSource objects that wouldn't
require the use of GMutex.
GSource, GCancellable and std::function<> objects are now packed
into an internal Context structure. Using the C++11 move semantics
it's simple to, at the time of dispatch, move the current context
out of the GMainLoopSource object in case the dispatch causes a
rescheduling on that same object.
All the schedule*() methods and the cancelInternal() method callers
now lock the GMutex to ensure no one else is accessing the data at
that moment. Similar goes for the dispatch methods, but those do
the dispatch and possible destruction duties with the mutex unlocked.
The dispatch can cause rescheduling on the same GMainLoopSource object,
which must not be done with a locked mutex.

Fix handling of attributes prior to compiling shader
https://bugs.webkit.org/show_bug.cgi?id=132430
Reviewed by Dean Jackson.
WebGL programs that called bindAttribLocations prior to compiling shader sources
would perform the bind using the non-hashed symbol name, but would later create
the attributes as hashed names. Consequently, the program would refer to
attributes that were never actually part of any shader, resulting in some amazing
display artifacts.
This patch adds a dictionary of hashed symbol names so that we can tell the WebGL
program the proper name that will be used when the shader is eventually compiled,
allowing the WebGL program to link against the proper symbol after compiling and
linking completes.

HW_AVAILCPU is more canonical than HW_NCPU. For example if you use hacks to tell Darwin

HW_NCPU doesn't reflect how much actual paralellism you'll get; it's merely reporting
facts about the machine you're running on. HW_AVAILCPU is almost always what WebKit
wants since it uses this information to decide how many threads to launch for various

[GLIB] Add GMainLoopSource class to wrap idle and timeout sources
https://bugs.webkit.org/show_bug.cgi?id=130027
Reviewed by Martin Robinson.
GLib main loop sources like idle and timeouts are sometimes
unconvenient to use and it's very common to forget canceling the
source when the object is destroyed or reset the source ID in the
callback when called. GMainLoopSource is a wrapper class to make it
easier to handle sources and also to avoid those typical mistakes.
It forces to create sources with a name and the user doesn't have
to deal with the source ID anymore. The source is cancelled when
the object is deleted or when a new source is scheduled. It uses
std::function for callbacks so that we no longer need to use the
"proxy" static callbacks either. We can use std::bind to use a
function pointer or a member or even lambda functions. It also handles
repeating sources automatically depending on whether the given
function returns a bool or not.

https://bugs.webkit.org/show_bug.cgi?id=130288
Reviewed by Filip Pizlo.
Added ability to change thread priorities relative to its current priority.
Created options to adjust the priority of the DFG and FTL compilation work thread
pools. For two core systems, there might be three runnable threads, the main thread,
the DFG compilation thread and the FTL compilation thread. With the same priority,
the scheduler is free to schedule whatever thread it wants. By lowering the
compilation threads, the main thread can run. Further tests may suggest better values
for the new options, priorityDeltaOfDFGCompilerThreads and priorityDeltaOfFTLCompilerThreads.
For a two-core device, this change has a net positive improvement of 1-3% across
SunSpider, Octane, Kraken and AsmBench.

Remove the global operator new/operator delete overrides. Having ALWAYS_INLINE operators
like we do is really undefined behavior according to the C++ standard and we've been lucky enough
to get away with it so far, but any code that calls operator new/operator delete inside from the C++ standard
library (not from headers that are included) will be mismatched and potentially crash. libc++ calls
delete in it's std::thread implementation for example.
The only supported way to override operator new and operator delete globally is to not use inline
functions, but that would mean that any application using WebKit would not be able to provide custom
operator new/operator delete functions so we'll just reuse the already existing infrastructure consisting
of the WTF_MAKE_FAST_ALLOCATED macro.

Vector with inline capacity should work with non-PODs
https://bugs.webkit.org/show_bug.cgi?id=128864
Reviewed by Michael Saboff.
Previously, we would copy the inline storage of a vector as if it was a bag of bits.
This presumed that the element type was relocatable. In general this is only true for
PODs.
This patch changes this by introducing a swap operation over inline storage. This swap
operation requires being told about the size that is in use.
Deques would have required some cleverness to make this work, because the swap
operation needs to know which subset of elements are in-use and assumes that a size is
sufficient for this. That's not true for deques. Instead of trying to do very clever
things, I just removed the inline capacity option from Deque. I believe that this is
fine since there are only two users of Deque with inline capacity, and both of them
appear to be allocated rarely enough that inline capacity probably doesn't help much.

GUniqueOutPtr is a simplified version of GOwnPtr for the cases

container pointer. The API is very simple to make sure this is
only used when outPtr() is needed. It can't be constructed with a
pointer, and there's not method to set a new pointer. Another
difference with the old GOwnPtr is that outPtr() can be used
multiple times, because it frees any pointer previously set.

The stack limit computation does not work for Windows.
<https://webkit.org/b/128226>
Reviewed by Geoffrey Garen.
The current stack limit computation assumes that the stack is allocated
in high memory. On Windows, the stack seems to be allocated very near
address 0, and is smaller in size than our Options::maxPerThreadStackUsage().
This combination triggers a bug where StackBounds::recursionLimit()
underflows and computes a limit address that is ridiculously high in memory.
The net effect is that the Windows port thinks its out of stack space all
the time.
We now check for potential underflows in StackBounds and return an
appropriate limit address.

GOwnPtr::outPtr() doesn't seem to be possible to implement with

Add a new StringView class which is an immutable reference to either an 8-bit or a 16-bit string.
This makes it easier to pass substrings around without having to either copy string data

The StringView class is very loosely based on the std::string_view class which is proposed for a future version of C++,

Refactor NSActivity handling code from ChildProcess to UserActivity
https://bugs.webkit.org/show_bug.cgi?id=126330
Reviewed by Sam Weinig.
UserActivity is a mechanism to express to the operating system (where appropriate)
that a user initiated activity is taking place, and as such that resources should be
made available to the process accordingly.
Currently we hold a single NSActivity, at the WebKit layer. This refactoring allows us
to hold different activity tokens for different user actions (which simplifies the
handling, and aides debugging since the token can more accurately express the activity
taking place), and also will allow us to avoid the layering difficulty of calling back
up the stack to WebKit to register that an activity is taking place.
* wtf/Platform.h:

Give Unique StringImpls a meaningful data pointer
https://bugs.webkit.org/show_bug.cgi?id=125598
Reviewed by Michael Saboff.
Found by code inspection. If there is a collision in an Identifier
table when comparing to a string literal we attempt to use the data
pointer (essentially this ends up being a null termination check).
Previously unique pointers just used the literal 1 as the data address
but this obviously fails when dereferenced. Instead we now make the
data pointer point to the location of the buffer pointer itself. As
the buffer pointer is initialised to 0, this satisfies the requirement
that the 0-length unique string is null terminated.

Added a get() helper to facilitate writing functions that
construct a new object and call some functions on it before
returning it.
(WTF::PassRef::dropRef):
This will deref() the referenced object and mark the PassRef
as "passed." This is used in code paths where the PassRef is
going to go out of scope with nobody to take it over.

Renamed takeReference() to leakRef() and made it public so
we don't have to awkwardly sink the PassRef into a Ref for
e.g static locals.
