Ben Noordhuis	8350f3a3a2	buffer: optimize Buffer#toString() Break up Buffer#toString() into a fast and slow path. The fast path optimizes for zero-length buffers and no-arg method invocation. The speedup for zero-length buffers is a satisfying 700%. The no-arg toString() operation gets faster by about 13% for a one-byte buffer. This change exploits the fact that most Buffer#toString() calls are plain no-arg method calls. Rewriting the method to take no arguments means a call doesn't go through an ArgumentsAdaptorTrampoline stack frame in the common case.

Brendan Ashworth	9da168b71f	buffer: optimize Buffer.byteLength Buffer.byteLength is important for speed because it is called whenever a new Buffer is created from a string. This commit optimizes Buffer.byteLength execution by: - moving base64 length calculation into JS-land, which is now much faster - remove redundant code and streamline the UTF8 length calculation It also adds a benchmark and better tests.

Vladimir Kurchatkin	45d8d9f826	buffer: implement `iterable` interface This makes possible to use `for..of` loop with buffers. Also related `keys`, `values` and `entries` methods are added for feature parity with `Uint8Array`.

isaacs	3e1b1dd4a9	Remove excessive copyright/license boilerplate The copyright and license notice is already in the LICENSE file. There is no justifiable reason to also require that it be included in every file, since the individual files are not individually distributed except as part of the entire package.	10 years ago
Nick Apperson	ee95e4f5f7	buffer: improve {read,write}{U}Int* methods Increase the performance and simplify the logic of Buffer#write{U}Int* and Buffer#read{U}Int* methods by placing the byte manipulation code directly inline. Also improve the speed of buffer-write benchmarks by creating a new call directly to each method by using Function() instead of calling by buff[fn].

Ben Noordhuis	8ae32a9864	bench: fix buffers/buffer-base64-encode benchmark The test is supposed to measure the performance of the base64 encoder so move the Buffer#write() calls out of the benchmark section. The overhead of the calls isn't terrible (about 1-3%) but having unrelated activity in a micro-benchmark is never a good idea. Signed-off-by: Trevor Norris <trev.norris@gmail.com>	11 years ago

Sean McArthur	226f98a356	buffer: add compare and equals methods compare() works like String.localeCompare such that: Buffer.compare(a, b) === a.compare(b); equals() does a native check to see if two buffers are equal. Signed-off-by: Trevor Norris <trev.norris@gmail.com>	11 years ago
