Turns out that we don't use node_object_wrap.h any more in core,
and, with v8 3.21, it's breaking our Windows build. Removing refs
to it everywhere (and adding node.h in one case where it was the
only way node.h was being included), we have restored the Windows
build.
Previous behaviour was to drop to an openssl prompt
("Enter PEM pass phrase:") when supplying a private key with a
passphrase. This change adds a fourth, optional, paramter that
will be used as the passphrase.
To include this parameter in a backwards compatible way it was
necessary to expose the previously undocumented (and unexposed)
feature of being able to explitly setting the output encoding.
Drop the ObjectWrap dependency in favor of an internal WeakObject class.
Let's us stop worrying about API and ABI compatibility when making
changes to the way node.js deals with weakly persistent handles
internally.
The default entropy source is /dev/urandom on UNIX platforms, which is
okay but we can do better by seeding it from OpenSSL's entropy pool.
On Windows we can certainly do better; on that platform, V8 seeds the
random number generator using only the current system time.
Fixes#6250.
Fix pointer unwrapping when T is a class with more than one base class.
Before this commit, the wrapped void* pointer was cast directly to T*
without going through ObjectWrap* first, possibly leading to a class
instance pointer that points to the wrong vtable.
This change required some cleanup in various files; some classes
used private rather than public inheritance, others didn't derive
from ObjectWrap at all...
Fixes#6188.
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.

Before this commit it was declared static (in a header file!), meaning
it got duplicated in every file that includes it.
A few duplicated pointers is not the end of the world but it introduces
a lot of potential for confusion because root_cert_store in file A is
not the root_cert_store in file B.
Moral of the story: don't declare static variables in header files.
Commit 03e008d introduced src/tls_wrap.cc and src/tls_wrap.h but
said files copied on the order of 1 kLoC from src/node_crypto.cc
and src/node_crypto.h. This commit undoes some of the duplication.
Fixes#6024.
Code cleanup: don't call a Connection object `p` in some places, `c` in
other places and `ss` in yet other places. Let's just call it `conn`.
This also fixes about a million style errors in one fell swoop.
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.)
Quote from SSL_shutdown man page:
The output of SSL_get_error(3) may be misleading,
as an erroneous SSL_ERROR_SYSCALL may be flagged even though
no error occurred.
Also, handle all other errors to prevent assertion in `ClearError()`.
Add the `sessionTimeout` integral value to the list of options
recognized by `tls.createServer`.
This option will be useful for applications which need frequently
establish short-lived TLS connections to the same endpoint. The TLS
tickets RFC is an ideal option to reduce the socket setup overhead
for such scenarios, but the default ticket timeout value (5
minutes) is too low to be useful.
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.
The TLS protocol allows (and sometimes requires) clients to renegotiate the
session. However, renegotiation requires a disproportional amount of server-side
resources, particularly CPU time, which makes it a potential vector for
denial-of-service attacks.
To mitigate this issue, we keep track of and limit the number of renegotiation
requests over time, emitting an error if the threshold is exceeded.
SecureContext.setOptions() is backed by SSL_CTX_set_options() which, contrary to
what the name suggests, is additive: it doesn't set options, it adds them to the
already active options.
Hence the need for SecureContext.clearOptions(), which lets you unset active
options.
