In very unlikely case, where `deflateInit2()` may return error (right
now happening only on exhausting all memory), the `ZCtx::Error()` will
be called and will try to `Unref()` the handle. But the problem is that
this handle was never `Ref()`ed, so it will trigger an assertion error
and crash the program.

* child_process: properly support optional args (cjihrig)
* crypto: Disable autonegotiation for SSLv2/3 by default (Fedor Indutny,
Timothy J Fontaine, Alexis Campailla)
This is a behavior change, by default we will not allow the negotiation to
SSLv2 or SSLv3. If you want this behavior, run Node.js with either
`--enable-ssl2` or `--enable-ssl3` respectively.
This does not change the behavior for users specifically requesting
`SSLv2_method` or `SSLv3_method`. While this behavior is not advised, it is
assumed you know what you're doing since you're specifically asking to use
these methods.
Always set ssl2/ssl3 disabled based on whether they are enabled in Node.
In some corner-case scenario, node with OPENSSL_NO_SSL3 defined could
be linked to openssl that has SSL3 enabled.
This change disables SSLv2/SSLv3 use by default, and introduces a
command line flag to opt into using SSLv2/SSLv3.
SSLv2 and SSLv3 are considered unsafe, and should only be used in
situations where compatibility with other components is required and
they cannot be upgrade to support newer forms of TLS.

When backporting f8193ab into v0.10, a regression was introduced. Timers
with non-integer timeout could trigger a infinite recursion with 100%
cpu usage. This commit backports 93b0624 which fixes the regression.
After backporting f8193ab, instead of using Date.now(), timers would use
Timer.now() to determine if they had expired. However, Timer.now() is
based on loop->time, which is not updated when a timer's remaining time
is > 0 and < 1. Timers would thus never timeout if their remaining time
was at some point > 0 and < 1.
With this commit, Timer.now() updates loop->time itself, and timers
always timeout eventually.
Fixes#8065 and #8068.
Original commit message:
timers: use uv_now instead of Date.now
This saves a few calls to gettimeofday which can be expensive, and
potentially subject to clock drift. Instead use the loop time which
uses hrtime internally.
In addition to the backport, this commit:
- keeps _idleStart timers' property which is still set to
Date.now() to avoid breaking existing code that uses it, even if
its use is discouraged.
- adds automated tests. These tests use a specific branch of
libfaketime that hasn't been submitted upstream yet. libfaketime
is git cloned if needed when running automated tests.

* utf8: Prevent Node from sending invalid UTF-8 (Felix Geisendörfer)
- *NOTE* this introduces a breaking change, previously you could construct

UTF-8, now unmatched surrogate pairs are replaced with the unknown UTF-8
character. To restore the old functionality simply have NODE_INVALID_UTF8
environment variable set.

Previously v8's WriteUtf8 function would produce invalid utf-8 output
when encountering unmatched surrogate code units [1]. The new
REPLACE_INVALID_UTF8 option fixes that by replacing invalid code points
with the unicode replacement character.
[1]: JS Strings are defined as arrays of 16 bit unsigned integers. There
is no unicode enforcement, so one can easily end up with invalid unicode
code unit sequences inside a string.
ClientHelloParser used to contain an 18k buffer that was kept around
for the life of the connection, even though it was not needed in many
situations. I changed it to be deallocated when it's determined to
be no longer needed.

Fix the following compiler warning on systems where _XOPEN_SOURCE is
defined by default:
../src/node_constants.cc:35:0: warning: "_XOPEN_SOURCE" redefined
#define _XOPEN_SOURCE 500
Move the (re)definition of _XOPEN_SOURCE to the top of the file while
we're here. Commit 00890e4 adds a `#define _XOPEN_SOURCE 500` in order
to make <fcntl.h> expose O_NONBLOCK but it does so after other system
headers have been included. If those headers include <fcntl.h>, then
the #include in node_constants.cc will be a no-op and O_NONBLOCK won't
be visible.

`process.uptime()` interface will return the amount of time the
current process has been running. To achieve this it was caching the
`uv_uptime` value at program start, and then on the call to
`process.uptime()` returning the delta between the two values.
`uv_uptime` is defined as the number of seconds the operating system
has been up since last boot. On sunos this interface uses `kstat`s
which can be a significantly expensive operation as it requires
exclusive access, but because of the design of `process.uptime()` node
*had* to always call this on start. As a result if you had many node
processes all starting at the same time you would suffer lock
contention as they all tried to read kstats.
Instead of using `uv_uptime` to achieve this, the libuv loop already
has a concept of current loop time in the form of `uv_now()` which is
in fact monotonically increasing, and already stored directly on the
loop. By using this value at start every platform performs at least
one fewer syscall during initialization.
Since the interface to `uv_uptime` is defined as seconds, in the call
to `process.uptime()` we now `uv_update_time` get our delta, divide by
1000 to get seconds, and then convert to an `Integer`. In 0.12 we can
move back to `Number::New` instead and not lose precision.
Caveat: For some platforms `uv_uptime` reports time monotonically
increasing regardless of system hibernation, `uv_now` interface is
also monotonically increasing but may not reflect time spent in
hibernation.
Ensure that OpenSSL has enough entropy (at least 256 bits) for its PRNG.
The entropy pool starts out empty and needs to fill up before the PRNG
can be used securely.
OpenSSL normally fills the pool automatically but not when someone
starts generating random numbers before the pool is full: in that case
OpenSSL keeps lowering the entropy estimate to thwart attackers trying
to guess the initial state of the PRNG.
When that happens, we wait until enough entropy is available, something
that normally should never take longer than a few milliseconds.
Fixes#7338.
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.
NB: This is a back-port of commit 7ac2391 from the master branch that
for some reason never got back-ported to the v0.10 branch.
The default on UNIX platforms in v0.10 is different and arguably worse
than it is with master: if no entropy source is provided, V8 3.14 calls
srandom() with a xor of the PID and the current time in microseconds.
That means that on systems with a coarse system clock, the initial
state of the PRNG may be easily guessable.
The situation on Windows is even more dire because there the PRNG is
seeded with only the current time... in milliseconds.
It's currently not really possible to compile native add-ons with
-fvisibility=hidden because that also hides the struct containing
the module definition.
The NODE_MODULE() and NODE_MODULE_DECL() macros are structured in
a way that makes it impossible to add a visibility attribute manually
so there is no escape hatch there.
That's why this commit adds an explicit visibility attribute to
the module definition. It doesn't help with node.js releases that
are already out there but at least it improves the situation going
forward.
Previously if you cached process.nextTick and then require('domain')
subsequent nextTick() calls would not be caught because enqueued
functions were taking the wrong path. This keeps nextTick to a single
function reference and changes the implementation details after domain
has been required.
Update the list of root certificates in src/node_root_certs.h with
tools/mk-ca-bundle.pl and update src/node_crypto.cc to make use of
the new format.
