In cases where many small writes are made to a stream
lacking _writev, the array data structure backing the
WriteReq buffer would greatly increase GC pressure.
Specifically, in the fs.WriteStream case, the
clearBuffer routine would only clear a single WriteReq
from the buffer before exiting, but would cause the
entire backing array to be GC'd. Switching to [].shift
lessened pressure, but still the bulk of the time was
spent in memcpy.
This replaces that structure with a linked list-backed
queue so that adding and removing from the queue is O(1).
In the _writev case, collecting the buffer requires an
O(N) loop over the buffer, but that was already being
performed to collect callbacks, so slowdown should be
neglible.

Before this change, _unrefActive would keep the unrefList sorted when
adding a new timer.
Because _unrefActive is called extremely frequently, this linear scan
(O(n) at worse) would make _unrefActive show high in the list of
contributors when profiling CPU usage.
This commit changes _unrefActive so that it doesn't try to keep the
unrefList sorted. The insertion thus happens in constant time.
However, when a timer expires, unrefTimeout has to go through the whole
unrefList because it's not ordered anymore.
It is usually not large enough to have a significant impact on
performance because:
- Most of the time, the timers will be removed before unrefTimeout is
called because their users (sockets mainly) cancel them when an I/O
operation takes place.
- If they're not, it means that some I/O took a long time to happen, and
the initiator of subsequents I/O operations that would add more timers
has to wait for them to complete.
With this change, _unrefActive does not show as a significant
contributor in CPU profiling reports anymore.
Fixes#8160.

The test wasn't checking directly that an assertion was thrown. Instead,
it was checking that spawn did not sucessfully spawn a non-existent
command.
However, the command chosen, dir, exists in GNU coreutils, so it exists
on Linux (though not on BSD derived OS X). The test as written passed on
Linux, even with the TypeError it is supposed to be checking for deleted
from spawn(). It would also pass on Windows if a ls.exe existed.
The approach is unnecessarily obscure, assert.throw() is for asserting
code throws, using it is more clear and works regardless of what
commands do or do not exist.

Currently when a server receives a new connection the underlying socket

Add a test that goes through the whole matrix of:
- command line options (--enable-ssl*)
- secureOptions
- secureProtocols
and makes sure that compatible test setups actually work as expected.
The test works by spawning two processes for each test case: one client
and one server. The test passes if a SSL/TLS connection from the client
to the server is successful and the test case was supposed to pass, or
if the connection couldn't be established and the test case was supposed
to fail.
The test is currently located in the directory 'test/external' because
it has external dependencies.
In the case of a pipe'd input, i.e. from the CI the fd will be a PIPE
and when listen() is called it will return ENOTSOCK instead of EINVAL.
Backport: cd2d3aedaa
The order of the callbacks is non-deterministic, so don't expect the
error messages to come back in the same order every time, instead just
verify they are expected messages.
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.
Because of constant-timeness change made in openssl-1.0.1j the error is
no longer returned from EVP_DecryptFinal_ex. Now it just return 0, and
thus the error message does not contain proper error code. Adapt to this
change, there is not much that we could do about it.
You cannot spawn 'dir' on Windows because it's not an executable. Also,
some people might have 'ls' on their path on Windows, so I changed
invalidCmd to something that's highly unlikely to exist.

Since we are taking control of the microtask queue it makes sense to

isolate->SetAutorunMicrotasks(false) would cause _tickCallback() not to
be called.
Automatically running the microtask queue will cause it to run:
* After callback invocation
* Inside _tickCallback()
* After _tickCallback() invocation
The third one is unnecessary as the microtask queue is guaranteed to be
empty at this point. The first only needs to be run manually when
_tickCallback() isn't going to be called by MakeCallback().
