        <rdar://problem/5487107> NULL dereference crash in FastMallocZone::enumerate when running leaks against Safari

        Storing remote pointers to their local equivalents in mapped memory was leading to the local pointer being
        interpreted as a remote pointer.  This caused a crash when using the result of mapping this invalid remote pointer.
        The fix is to follow the pattern used elsewhere in FastMallocZone by always doing the mapping after reading and
        never storing the mapped pointer.

        Fixed <rdar://problem/5429064> 141885 Safari JavaScript: Math.random() slightly less randomly distributed than on Safari / Mac

        Math.random was skewed slightly upward because it assumed that RAND_MAX was outside the range of
        values that rand() might return. This problem was particularly pronounced on Windows because
        the range of values returned by rand() on Windows is 2^16 smaller than the range of values
        return by rand() on Mac.
        
        Fixed by accounting for RAND_MAX return values. Also, switched Windows over to rand_s, which has
        a range that's equal to rand()'s range on Mac.

        - Added Vector::appendRange(), which appends to a vector based on a given start and end iterator
        - Added keys() and values() functions to HashMap iterators, which give keys-only and values-only iterators
        
        Together, these allow easy copying of a set, or the keys or values of a map, into a Vector. Examples:
        
        HashMap<int, int> map;
        HashSet<int> set;
        Vector<int> vec;
        // ...
        vec.appendRange(set.begin(), set.end());
        vec.appendRange(map.begin().keys(), map.end().keys());
        vec.appendRange(map.begin().values(), map.end().values());

        This also allows for a slightly nicer syntax when iterating a map. Instead of saying 
        (*it)->first, you can say *it.values(). Similarly for keys. Example:
        
        HashMap<int, int>::const_iterator end = map.end();
        for (HashMap<int, int>::const_iterator it = map.begin(); it != end; ++it)

        <rdar://problem/5352887> "Out of memory" error during repeated JS string concatenation leaks hundreds of MBs of RAM

        A call to fastRealloc was failing which lead to UString::expandCapacity leaking the buffer it was trying to reallocate.
        It also resulted in the underlying UString::rep having both a null baseString and buf field, which meant that attempting
        to access the contents of the string after the failed memory reallocation would crash.

        A third issue is that expandedSize size was calculating the new length in a way that led to an integer overflow occurring.
        Attempting to allocate a string more than 190,000,000 characters long would fail a the integer overflow would lead to a
        memory allocation of around 3.6GB being attempted rather than the expected 390MB.  Sizes that would lead to an overflow
        are now  returned as zero and callers are updated to treat this as though the memory allocation has failed.

        - JavaScriptCore part of fix for <rdar://problem/5300291> Optimize GC to reclaim big, temporary objects (like XMLHttpRequest.responseXML) quickly
        
        Also, as a side effect of optimizations included in this patch:
        - 7% speedup on JavaScript iBench
        - 4% speedup on "Celtic Kane" JS benchmark
        
        The basic idea is explained in a big comment in collector.cpp. When unusually 
        large objecs are allocated, we push the next GC closer on the assumption that
        most objects are short-lived.
        
        I also did the following two optimizations in the course of tuning
        this not to be a performance regression:

        1) Change UString::Rep to hold a self-pointer as the baseString in
        the unshared case, instead of a null pointer; this removes a
        number of null checks in hot code because many places already
        wanted to use the rep itself or the baseString as appropriate.
        
        2) Avoid creating duplicate StringImpls when creating a
        StringInstance (the object wrapper for a JS string) or calling
        their methods. Since a temporary wrapper object is made every time
        a string method is called, this resulted in two useless extra
        StringImpls being allocated for no reason whenever a String method
        was invoked on a string value. Now we bypass those.

        - fix <rdar://problem/5345440> PCRE computes wrong length for expressions with quantifiers
          on named recursion or subexpressions

        It's challenging to implement proper preflighting for compiling these advanced features.
        But we don't want them in the JavaScript engine anyway.

        Turned off the following features of PCRE (some of these are simply parsed and not implemented):

            \C \E \G \L \N \P \Q \U \X \Z
            \e \l \p \u \z
            [::] [..] [==]
            (?#) (?<=) (?<!) (?>)
            (?C) (?P) (?R)
            (?0) (and 1-9)
            (?imsxUX)

        Added the following:

            \u \v

        Because of \v, the js1_2/regexp/special_characters.js test now passes.

        To be conservative, I left some features that JavaScript doesn't want, such as
        \012 and \x{2013}, in place. We can revisit these later; they're not directly-enough
        related to avoiding the incorrect preflighting.

        I also didn't try to remove unused opcodes and remove code from the execution engine.
        That could save code size and speed things up a bit, but it would require more changes.

        * kjs/regexp.h:
        * kjs/regexp.cpp: (KJS::RegExp::RegExp): Remove the sanitizePattern workaround for

        * pcre/pcre_compile.c: Added a different escape table for when JAVASCRIPT is set that

        and added code to handle '\u2013' inside JAVASCRIPT.

        don't want.

        (WTF::): Instead of doing type-punned assignments via pointer cast, do one of three things:
        (1) assign directly w/o cast if storage type matches real type; (2) assign using cast
        via union if type does not need reffing; (3) copy with memcpy and ref/deref manually if type
        needs reffing. This is ok peref-wise because memcpy of a constant length gets optomized.
        HashTraits are now expected to make ref()/deref() take the storage type, not the true type.
        * wtf/HashSet.h:
        (WTF::): Same basic idea.
        * wtf/HashTable.h:

        (WTF::ListHashSetNodeAllocator::allocate): Added assertions based on a debug-only
        m_isAllocated flag that make sure we don't allocate a block that's already allocated.
        These assertions helped pinpoint the bug. Set m_isDoneWithInitialFreeList when we
        allocate the last block of the initial free list. Once we're done with the initial
        free list, turn off the rule that says that the next node in the pool after the last
        node in the free list is also free. This rule works because any free nodes are added
        to the head of the free list, so a node that hasn't been allocated even once is always
        at the tail of the free list and all the nodes after it also haven't been allocated
        even once. But it doesn't work any longer once the entire pool has been used at least
        once, because there's nothing special about the last node on the free list any more.
        (WTF::ListHashSetNodeAllocator::deallocate): Set the node's m_isAllocated to false.
        (WTF::ListHashSetNodeAllocator::pastPool): Added. Used above.

        Despite the ECMAScript specification's claim that you can treat these as syntax

        - discard the arguments List for an ActivationImp when the corresponding Context is destroyed (1.7% speedup)
        http://bugs.webkit.org/show_bug.cgi?id=13385

        Based an idea by Christopher E. Hyde <C.Hyde@parableuk.force9.co.uk>. His patch to do 
        this also had many other List changes and I found this much simpler subset of the changes
        was actually a hair faster.
        
        This optimization is valid because the arguments list is only kept around to
        lazily make the arguments object. If it's not made by the time the function
        exits, it never will be, since any function that captures the continuation will
        have its own local arguments variable in scope.
        
        Besides the 1.7% speed improvement, it shrinks List by 4 bytes
        (which in turn shrinks ActivationImp by 4 bytes).

        Bug 13029: Permit NPAPI plug-ins to see HTTP response headers.
        This doesn't actually change JavaScriptCore, but that's where npapi.h is.

        * bindings/npapi.h:
        Add headers member to NPStream struct.  Also increase NP_VERSION_MINOR to 18.
        Increasing to >= 17 allows plug-ins to safely detect whether to look for
        NPStream::headers.  Increasing from 17 to 18 reflects presence of NPObject
        enumeration, which was added in a prior patch, and which has been agreed to
        constitute version 18 by the plugin-futures list.  Also add other missing
        bits of npapi.h to catch up from 14 to 18.  This includes features that are
        not implemented in WebKit, but those are safely stubbed.

        * kjs/value.h: Remove unneeded empty virtual destructor from JSValue.
        The only class derived from JSValue is JSCell and it already has a
        virtual destructor. Declaring an empty constructor in JSValue had one
        good effect: it marked the destructor private, making it a compile
        time error to try to destroy a JSValue; but that's not a likely
        mistake for someone to make. It had two bad effects: (1) it caused gcc,
        at least, to generate code to fix up the virtual table pointer to
        point to the JSValue version of the virtual table inside the destructor
        of all classes derived from JSValue directly or indirectly; (2) it
        caused JSValue to be a polymorphic class so required a virtual table for
        it. It's cleaner to not have either of those.

        Unfortunately, the bindings depend on UString and Identifier as string 
        representations. So, they need to acquire the JSLock when doing something
        that will ref/deref their strings.

        Layout tests, the original site, and Java, Flash, and Quicktime on the 
        web work. No leaks reported. No automated test for this because testing

        Fixed <rdar://problem/4587763> PAC file: lock inversion between QT and 
        JSCore causes a hang @ www.panoramas.dk
        
        With a PAC file, run-webkit-tests --threaded passes, the reported site
        works, and all the Quicktime/JavaScript and Flash/JavaScript examples
        I found through Google work, too.
        
        Any time JavaScript causes arbitrary non-JavaScript code to execute, it 
        risks deadlock, because that code may block, trying to acquire a lock 
        owned by a thread that is waiting to execute JavaScript. In this case,
        the thread was a networking thread that was waiting to interpret a PAC file.
        
        Because non-JavaScript code may execute in response to, well, anything,
        a perfect solution to this problem is impossible. I've implemented an
        optimistic solution, instead: JavaScript will drop its lock whenever it
        makes a direct call to non-JavaScript code through a bridging/plug-in API,
        but will blissfully ignore the indirect ways it may cause non-JavaScript 
        code to run (resizing a window, for example). 
        
        Unfortunately, this solution introduces significant locking overhead in 
        the bridging APIs. I don't see a way around that.

        This patch includes some distinct bug fixes I saw along the way:
        
        * bindings/objc/objc_instance.mm: Fixed a bug where a nested begin() call
        would leak its autorelease pool, because it would NULL out _pool without
        draining it.

        * bindings/runtime_object.cpp:
        (RuntimeObjectImp::methodGetter): Don't copy an Identifier to ASCII only
        to turn around and make an Identifier from the ASCII. In an earlier

        just unnecessary work.
        (RuntimeObjectImp::getOwnPropertySlot): ditto

        * bindings/objc/objc_instance.h: Removed overrides of setVAlueOfField and
        getValueOfField, because they did exactly what the base class versions did.
        Removed overrides of Noncopyable declarations for the same reason.

        * bindings/runtime.h: Inherit from Noncopyable instead of rolling our own.
        * bindings/c/c_instance.h: ditto

        fact that C++ unwinding of DropAllLocks goes crazy when you put it inside
        a @try block. I moved all JavaScript stuff outside of the @try blocks, and 
        then prefixed the whole blocks with DropAllLocks objects. This required some

        * kjs/JSLock.cpp: 
        (1) Fixed DropAllLocks to behave as advertised, and drop the JSLock only 
        if the current thread actually acquired it in the first place. This is 
        important because WebKit needs to ensure that the JSLock has been 
        dropped before it makes a plug-in call, even though it doesn't know if 
        the current thread actually acquired the JSLock. (We don't want WebKit
        to accidentally drop a lock belonging to *another thread*.)
        (2) Used the new per-thread code written for (1) to make recursive calls
        to JSLock very cheap. JSLock now knows to call pthread_mutext_lock/ 
        pthread_mutext_unlock only at nesting level 0.

        Made the fastMalloc isForbidden flag per thread. (Oops!) We expect that
        other threads will malloc while we're marking -- we just want to prevent
        our own marking from malloc'ing.
