buffer: write strings directly from call

Buffer(<String>) used to pass the string to js where it would then be
passed back to cpp for processing. Now only the buffer object
instantiation is done in js and the string is processed in cpp.

Also added a Buffer api that also accepts the encoding.

buffer: proper API export for Windows

So that Windows users can properly include smalloc and node_buffer,
NODE_EXTERN was added to the headers that export this functionality.

buffer: use smalloc as backing data store

Memory allocations are now done through smalloc. The Buffer cc class has
been removed completely, but for backwards compatibility have left the
namespace as Buffer.

The .parent attribute is only set if the Buffer is a slice of an...

buffer: DRY string encoding using StringBytes

This also templatizes the Buffer::*Slice functions, and the template
function probably cannot be safely used outside of Node. However, it
also SHOULD not be used outside of Node, so this is arguably a feature...

buffer: optimize Buffer.prototype.write(s, 'hex')

Move the implementation to C++ land. This is similar to commit 3f65916
but this time for the write() function and the Buffer(s, 'hex')
constructor.

Speeds up the benchmark below about 24x (2.6s vs 1:02m)....
3f65916f 02/01/2013 05:07 PM Ben Noordhuis

buffer: optimize Buffer.prototype.toString('hex')

Move the implementation to C++ land. The old JS implementation used
string concatenation, was dog slow and consumed copious amounts of
memory for large buffers. Example:

var buf = Buffer(0x1000000);  // 16 MB...

buffer: floating point read/write improvements

Improvements:
  • floating point operations are approx 4x's faster
  • Now write quiet NaN's
  • all read/write on floating point now done in C, so no more need for
    lib/buffer_ieee754.js
  • float values have more accurate min/max value checks...

src: use static_cast where appropriate

Use static_cast instead of reinterpret_cast when casting from void*
to another type.

This is mostly an aesthetic change but may help catch bugs when the
affected code is modified.

buffer: allocate memory with mmap()

Work around an issue with the glibc malloc() implementation where memory blocks
are never returned to the operating system when they are allocated with brk()
and have overlapping lifecycles.

Fixes #4283.

Revert support for isolates.

It was decided that the performance benefits that isolates offer (faster spin-up
times for worker processes, faster inter-worker communication, possibly a lower
memory footprint) are not actual bottlenecks for most people and do not outweigh...

dd527374 10/22/2010 07:52 PM Stéphan Kochen

Provide a C++ Buffer constructor for external storage.

In order to do this, buffer data management was moved out of the
JS entry-point New, and into Replace.

Secondly, the constructor makes an immediate call to Replace, and
in order for ArrayData calls to work, wrapping must already be set...
