For consistency with the newly added src/base64.h header, check that NODE_WANT_INTERNALS is defined and set in internal headers.

2016-05-24src: no abort from getter if object isn't wrappedTrevor Norris
v8::Object::GetAlignedPointerFromInternalField() returns a random value if Wrap() hasn't been run on the object handle. Causing v8 to abort if certain getters are accessed. It's possible to access these getters and functions during class construction through the AsyncWrap init() callback, and also possible in a subset of those scenarios while running the persistent handle visitor. Mitigate this issue by manually setting the internal aligned pointer field to nullptr in the BaseObject constructor and add necessary logic to return appropriate values when nullptr is encountered.

2015-08-20stream_base: various improvementsFedor Indutny
Expose and use in TLSWrap an `v8::External` wrap of the `StreamBase*` pointer instead of guessing the ancestor C++ class in `node_wrap.h`. Make use of `StreamBase::Callback` structure for storing/passing both callback and context in a single object. Introduce `GetObject()` for future user-land usage, when a child class is not going to be inherited from AsyncWrap.

2015-02-24streams: introduce StreamWrap and JSStreamFedor Indutny
Introduce a way to wrap plain-js `stream.Duplex` streams into C++ StreamBase's child class. With such method at hand it is now possible to pass `stream.Duplex` instance as a `socket` parameter to `tls.connect()`.

2015-02-22stream_base: introduce StreamBaseFedor Indutny
StreamBase is an improved way to write C++ streams. The class itself is for separting `StreamWrap` (with the methods like `.writeAsciiString`, `.writeBuffer`, `.writev`, etc) from the `HandleWrap` class, making possible to write abstract C++ streams that are not bound to any uv socket. The following methods are important part of the abstraction (which mimics libuv's stream API): * Events: * `OnAlloc(size_t size, uv_buf_t*)` * `OnRead(ssize_t nread, const uv_buf_t*, uv_handle_type pending)` * `OnAfterWrite(WriteWrap*)` * Wrappers: * `DoShutdown(ShutdownWrap*)` * `DoTryWrite(uv_buf_t** bufs, size_t* count)` * `DoWrite(WriteWrap*, uv_buf_t*, size_t count, uv_stream_t* handle)` * `Error()` * `ClearError()` The implementation should provide all of these methods, thus providing the access to the underlying resource (be it uv handle, TLS socket, or anything else). A C++ stream may consume the input of another stream by replacing the event callbacks and proxying the writes. This kind of API is actually used now for the TLSWrap implementation, making it possible to wrap TLS stream into another TLS stream. Thus legacy API calls are no longer required in `_tls_wrap.js`.

2014-10-23src: replace NULL with nullptrBen Noordhuis
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`.

Instead use the template functions in util.h.
2013-09-06src: add multi-context supportBen Noordhuis
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. This work was graciously sponsored by GitHub, Inc.
2013-08-07src: constify WITH_GENERIC_STREAM macroBen Noordhuis
Make the pointer-to-wrap const (i.e. mutable but not assignable) to prevent accidental reassignment in the macro body.
2013-08-07src: add IsEmpty() check to HasInstance()Ben Noordhuis
The check has virtually zero overhead and it simplifies the call sites because they were calling IsEmpty() anwyay.
2013-08-06src: fix WITH_GENERIC_STREAM() type check bugBen Noordhuis
The handle object was checked against the wrong constructor template. Put another way, it was unwrapped as the wrong StreamWrap type.

2013-07-06lib, src: upgrade after v8 api changeBen Noordhuis
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.)
