Instead of simply creating a new v8::Object to contain the connection
information, instantiate a new instance of a FunctionTemplate. This will
allow future improvements for debugging and performance probes.
Additionally, the "provider" argument in the ReqWrap constructor is no
longer optional.

Mark the matrix of copy/move constructor/assignment operator as deleted.
Prevents the object from being copied around (the macro already did that
pre-C++11), but also from being moved out.
Now that we are building with C++11 features enabled, replace use
of NULL with nullptr.
The benefit of using nullptr is that it can never be confused for
an integral type because it does not support implicit conversions
to integral types except boolean - unlike NULL, which is defined
as a literal `0`.
Attach the per-context execution environment directly to API functions.
Rationale:
* Gets node one step closer to multi-isolate readiness.
* Avoids multi-context confusion, e.g. when the caller and callee live
in different contexts.
* Avoids expensive calls to pthread_getspecific() on platforms where
V8 does not know how to use the thread-local storage directly.

Oversight to not pass blksize to fs.Stats on initialization.
Also added a test to make sure the object property has been set. Since
now on Windows both blksize and blocks will simply be set to undefined.
By building the fs.Stats object in JS, which is returned by all fs stat
functions, calls to v8::Object::Set() are removed. This also includes
creating all associated Date objects in JS, rather than using
v8::Date::New(). Both these changes have significant performance gains.
Note that the returned value from fs.stat changes slightly for non-POSIX
systems. Whereas before the stats object would be missing blocks and
blksize keys, it now has these keys with undefined as the value.

libuv gyp builds now require you to define the library disposition
(static or shared).
Also, libuv now supports vectored IO for file system reads and writes,
update to those function signatures
Built-in modules should be automatically registered, replacing the
static module list. Add-on modules should also be automatically
registered via DSO constructors. This improves flexibility in adding
built-in modules and is also a prerequisite to pure-C addon modules.
When `symlink`, `link` or `rename` report EEXIST, ENOTEMPTY or EPERM -
the destination file name should be included in the error message,
instead of source file name.
fix#6510
Create a HandleScope before calling the Environment::GetCurrent() that
takes a v8::Isolate* as an argument because it creates a handle with
the call to v8::Isolate::CurrentContext().
AsyncListener is a JS API that works in tandem with the AsyncWrap class
to allow the user to be alerted to key events in the life cycle of an
asynchronous event. The AsyncWrap class has its own MakeCallback
implementation that core will be migrated to use, and uses state sharing
techniques to allow quicker communication between JS and C++ whether the
async event callbacks need to be called.
This commit makes it possible to use multiple V8 execution contexts
within a single event loop. Put another way, handle and request wrap
objects now "remember" the context they belong to and switch back to
that context when the time comes to call into JS land.
This could have been done in a quick and hacky way by calling
v8::Object::GetCreationContext() on the wrap object right before
making a callback but that leaves a fairly wide margin for bugs.
Instead, we make the context explicit through a new Environment class
that encapsulates everything (or almost everything) that belongs to
the context. Variables that used to be a static or a global are now
members of the aforementioned class. An additional benefit is that
this approach should make it relatively straightforward to add full
isolate support in due course.
There is no JavaScript API yet but that will be added in the near
future.

Don't create an Integer when setting a numeric index on an object or an
array, use the version of v8::Object::Set() that takes an uint32_t.
Change the types of the variables from int to uint32_t and clean up
some code consistency issues while we're here.
* Change calls to String::New() and String::NewSymbol() to their
respective one-byte, two-byte and UTF-8 counterparts.
* Add a FIXED_ONE_BYTE_STRING macro that takes a string literal and
turns it into a v8::Local<v8::String>.
* Add helper functions that make v8::String::NewFromOneByte() easier to
work with. Said function expects a `const uint8_t*` but almost every
call site deals with `const char*` or `const unsigned char*`. Helps
us avoid doing reinterpret_casts all over the place.
* Code that handles file system paths keeps using UTF-8 for backwards
compatibility reasons. At least now the use of UTF-8 is explicit.
* Remove v8::String::NewSymbol() entirely. Almost all call sites were
effectively minor de-optimizations. If you create a string only once,
there is no point in making it a symbol. If you are create the same
string repeatedly, it should probably be cached in a persistent
handle.
Prior, strings would first be converted to a Buffer before being written
to disk. Now the intermediary step has been removed.
Other changes of note:
* Class member "must_free" was added to req_wrap so to track if the
memory needs to be manually cleaned up after use.
* External String Resource support, so the memory will be used directly
instead of copying out the data.
* Docs have been updated to reflect that if position is not a number
then it will assume null. Previously it specified the argument must be
null, but that was not how the code worked. An attempt was made to
only support == null, but there were too many tests that assumed !=
number would be enough.
* Docs update show some of the write/writeSync arguments are optional.
Before this commit, fs.chown() and fs.fchown() coerced the uid and gid
arguments to signed integers which is wrong because uid_t and gid_t are
unsigned on most all platforms and IDs that don't fit in a signed
integer do exist.
This commit changes the aforementioned functions to take unsigned ints
instead. No test because we can't assume the system has [GU]IDs that
large.
This change depends on joyent/libuv@d779eb5.
Fixes#5890.
Libuv now returns errors directly. Make everything in src/ and lib/
follow suit.
The changes to lib/ are not strictly necessary but they remove the need
for the abominations that are process._errno and node::SetErrno().
This is a big commit that touches just about every file in the src/
directory. The V8 API has changed in significant ways. The most
important changes are:
* Binding functions take a const v8::FunctionCallbackInfo<T>& argument
rather than a const v8::Arguments& argument.
* Binding functions return void rather than v8::Handle<v8::Value>. The
return value is returned with the args.GetReturnValue().Set() family
of functions.
* v8::Persistent<T> no longer derives from v8::Handle<T> and no longer
allows you to directly dereference the object that the persistent
handle points to. This means that the common pattern of caching
oft-used JS values in a persistent handle no longer quite works,
you first need to reconstruct a v8::Local<T> from the persistent
handle with the Local<T>::New(isolate, persistent) factory method.
A handful of (internal) convenience classes and functions have been
added to make dealing with the new API a little easier.
The most visible one is node::Cached<T>, which wraps a v8::Persistent<T>
with some template sugar. It can hold arbitrary types but so far it's
exclusively used for v8::Strings (which was by far the most commonly
cached handle type.)
While libuv supports reporting subsecond stat resolution across
platforms, to actually get that resolution your platform and filesystem
must support it (not HFS, ext[23], fat), otherwise the nsecs are 0
All compile time warnings about using deprecated APIs have been
suppressed by updating node's API. Though there are still many function
calls that can accept Isolate, and still need to be updated.
node_isolate had to be added as an extern variable in node.h and
node_object_wrap.h
Also a couple small fixes for Error handling.
Before v8 3.16.6 the error stack message was lazily written when it was
needed, which allowed you to change the message after instantiation.
Then the stack would be written with the new message the first time it
was accessed. Though that has changed. Now it creates the stack message
on instantiation. So setting a different message afterwards won't be
displayed.
This is not a complete fix for the problem. Getting error without any
message isn't very useful.
