v8 is faster at setting object properties in JS than C++. Even when it
requires calling into JS from native code. Make
process._getActiveRequests() faster by doing this when populating the
array containing request objects.
Simple benchmark:
for (let i = 0; i < 22; i++)
fs.open(__filename, 'r', function() { });
let t = process.hrtime();
for (let i = 0; i < 1e6; i++)
process._getActiveRequests();
t = process.hrtime(t);
console.log((t[0] * 1e9 + t[1]) / 1e6);
Results between the two:
Previous: 4406 ns/op
Patched: 690 ns/op 5.4x faster

Fixed an intermittent issue on AIX where the 100ms timeout was reached
before the 'connection' event was fired. This resulted in a failure as
serverConnection would be undefined and the assert.equal would throw an

after a connection has been made.

This adds an example of a semi-common promise pattern that could
result in false-positive 'unhandledRejection' events, to help motivate
why there is a dual 'rejectionHandled' event. I anticipate it being
helpful to users who encounter 'unhandledRejection' events that do not
stem from obvious typos such as the JSON.pasre example.
Also cleans up the promise rejection tracking sample. By using a Map
instead of array we can get O(1) deletion and actually record the errors.
And, fixed indentation and backtick usage there to align with the rest of

When v8 implemented proper one-byte string support Node's internal

was that "binary" encoding effectively became "latin-1" encoding.
Because of this and because one-byte strings are natively supported by
v8 the buffer encoding is not deprecated and will not be removed.

These changes affect the following functions and their synchronous
counterparts:
* fs.readFile()
* fs.writeFile()
* fs.appendFile()
If the first parameter is a uint32, it is treated as a file descriptor.
In all other cases, the original implementation is used to ensure
backwards compatibility. File descriptor ownership is never taken from
the user.
The documentation was adjusted to reflect these API changes. A note was
added to make the user aware of file descriptor ownership and the
conditions under which a file descriptor can be used by each of these
functions.
Tests were extended to test for file descriptor parameters under the
conditions noted in the relevant documentation.

heap: make array buffer maps disjoint
Remove intersection from the `std::map`s representing current live
ArrayBuffers. While being simpler to understand, it poses
significant performance issue for the active ArrayBuffer users (like
node.js).
Store buffers separately, and process them together during
mark-sweep phase.

4997.4 ns/op
4685.7 ns/op
NOTE: `fast` - was a patched node.js, `slow` - unpatched node.js

Backport 56a0a797f210e04746f2888116365d29a4bb6afc from V8 upstream to
include post-mortem metadata used by mdb_v8 to support V8 4.6.
Original commit message:
Update post-mortem metadata generation
mdb_v8, a post-mortem debugger for Node.js, now uses JSArrayBuffer's
backing_store property and JSArrayBufferView's byte_offset property to
get access to the content of Buffer instances in node (which are
Uint8Array instances). This change adds post-mortem metadata for these
two properties.
This change also fixes a typo in
inobject_properties_of_constructor_function_index_offset that was added
to gen-postmortem-metadata in a previous change. It should be named
inobject_properties_or_constructor_function_index instead.
