<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> 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> |
|||
Read more about these features in <a |
|||

|||
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 |
|||
some <a |

|||
|
|||
<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 |
|||
