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.)
The previous commit removes our patch that builds V8 at -O2 rather
than -O3 so there is not much point in keeping the configure switch
around.
The reason it did so was to work around an assortment of compiler and
linker bugs. In particular, certain combinations of g++ and binutils
generate bad or no code when -ffunction-sections or -finline-functions
is enabled (which -O3 implicitly does.)
It was quite the problem back in the day because everyone and his dog
built from source. Now that we have prebuilt binaries and packages
available, there is no longer a pressing need to be so accommodating.
If you experience spurious (or possibly not so spurious) segmentation
faults after this commit, you need to upgrade your compiler/linker
toolchain.
UsingDomains() assigned process_tickCallback when it had already
been set by MakeCallback() a few frames down the call stack.
Dispose the handle first or we'll retain whatever is in the lexical
closure of the old process._tickCallback function.
Fixes#5795.
If a transform stream has objectMode = true, it should
allow falsey values other than (null) like 0, false, ''.
null is reserved to indicate stream eof but other falsey
values should flow through properly.
Now that Buffer instantiation has improved, the SlabAllocator is an
unnecessary layer of complexity preventing further performance
optimizations.
Currently there is a small performance loss with very small stream
requests, but this will soon be addressed.
Assert that when the client closes it has seen an error, this prevents
the test from timing out.
Also queue a second write in the case that we were able to send the
buffer before the other side closed the connection.
There was previously up to a second exit delay when exiting node
right after an http request/response, due to the utcDate() function
doing a setTimeout to update the cached date/time.
Fixing this should increase the performance of our http tests.

Most TryCatch blocks have SetVerbose flag on, this tells V8 to report
uncaught exceptions to debugger.
FatalException handler is called from V8 Message listener instead from
the place where TryCatch was used. Otherwise uncaught exceptions are
logged twice.
See comment in `deps/v8/include/v8.h` for explanation of SetVerbose
flag:
> By default, exceptions that are caught by an external exception
> handler are not reported. Call SetVerbose with true on an
> external exception handler to have exceptions caught by the
> handler reported as if they were not caught.
The flag is used by `Isolate::ShouldReportException()`, which is called
by `Isolate::DoThrow()` to decide whether an exception is considered
uncaught.
Might cause write head running over read head, when there were no
allocation and `Commit()` was called. Source of at least one test
failure on windows (`simple/test-https-drain.js`).
Several people have reported cross-compiling build breakage, see e.g.

Subject: [nodejs] nodejs 0.10.12 and Angstrom issues
This reverts commit acbdabb74b.
gcc 4.2 on OS X gets confused about the call to node::Buffer::Data().
Fully qualify the function name to help it along.
Fixes the following build error:
../../deps/v8/include/v8.h: In function ‘char*
node::Buffer::Data(v8::Handle<v8::Value>)’:
../../deps/v8/include/v8.h:900: error: ‘class v8::Data’
is not a function,
../../src/node_buffer.h:38: error:
conflict with ‘char* node::Buffer::Data(v8::Handle<v8::Object>)’
../../src/node_buffer.cc:94: error:
in call to ‘Data’
Buffer(<String>) used to pass the string to js where it would then be
passed back to cpp for processing. Now only the buffer object
instantiation is done in js and the string is processed in cpp.
Also added a Buffer api that also accepts the encoding.
