<h2>Second Stable Branch of Node released</h2>
|
|
|
|
<p>
|
|
<a
|
|
href="https://github.com/ry/node/wiki/Migrating-from-v0.2-to-v0.3">Wiki
|
|
page detailing API changes between v0.4 and v0.2</a>
|
|
|
|
<p>
|
|
Major changes since v0.2:
|
|
|
|
<ul>
|
|
<li> Major overhaul of TLS/SSL system. Previously the binding to
|
|
OpenSSL was heavily interwoven into the socket code. This binding was
|
|
reworked to present each connection as a pair of "streams" instead: a
|
|
duplex encrypted stream and a duplex cleartext stream. The encrypted
|
|
stream is piped to a raw TCP socket using the general purpose
|
|
<code>Stream.prototype.pipe()</code> method. Functionality was
|
|
enhanced and API simplified.
|
|
|
|
<li>Simplier HTTP client API with connection pools.
|
|
|
|
<li> Cheaper <code>Buffer</code> allocation. Node uses
|
|
<code>Buffer</code> objects in many places - it was noticed that they
|
|
were relatively slow to allocate and difficult to garbage collect. The
|
|
implementation changed to use pure javascript objects instead of
|
|
an <code>ObjectWrap</code> which improved performance.
|
|
|
|
<li> With a good amount of experience now, some modifications to the
|
|
module loading system were made to better support package managers.
|
|
In particular, NPM was forced to resort to deep symlinks and "shim"
|
|
modules to work around missing features in <code>require()</code>. The main
|
|
changes are:
|
|
<ol>
|
|
<li><code>require()</code> calls realpath. That is,
|
|
it resolves symbolic links. This allows symlinked modules to make
|
|
relative requires.
|
|
|
|
<li><code>require()</code> now has a primitive understanding of
|
|
<code>package.json</code>. It looks for the <code>main</code>
|
|
script. This allows <code>require()</code> to work on package
|
|
directories directly.
|
|
|
|
<li>A specially named directory, <code>node_modules/</code>, is
|
|
searched in the current directory for any modules. This will
|
|
hopefully encourage programmers to bundle modules rather than
|
|
rely on a global namespace.
|
|
</ol>
|
|

|
|
module documentation</a>.
|
|
|
|
<li> A half-complete but good start a native windows build with MinGW
|
|
is underway by Bert Builder. Build instructions can be found <a
|
|
href="https://github.com/ry/node/wiki/Building-node.js-on-mingw">on
|
|
the wiki</a>.
|
|
|
|
<li> Node upgraded to the latest version of V8, <code>v3.1.2</code>.
|
|
This includes much work including V8's new compilation infrastructure
|
|
and a GDB plugin on Linux.

|
|
full V8 ChangeLog</a>.
|
|
|
|
<li>A new built-in client for V8's debugger was added to Node. It is
|
|
still very primitive but usable for simple task. There is a <a
|
|
href="http://vimeo.com/19465332">small introduction video</a> and

|
|
|
|
<li>An <code>os</code> module was added by Brian White which exposes
|
|
a lot of basic but useful system information: <code>os.cpus(),
|
|
os.freemem(), os.totalmem(), os.loadavg()</code>
|
|
|
|
<li> And, of course, many of bug fixes. See the
