Ben Noordhuis	cd42f56178	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). var s = 'f'; for (var i = 0; i < 26; ++i) s += s; // 64 MB Buffer(s, 'hex');	12 years ago
Ben Noordhuis	3f65916fa9	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 buf.toString('hex') // Used 3+ GB of memory. The new implementation operates in O(n) time and space. Fixes #4700.	12 years ago
Trevor Norris	22b84e6216	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 * add additional benchmarks for buffers read/write * created benchmark/_bench_timer.js which is a simple library that can be included into any benchmark and provides an intelligent tracker for sync and async tests * add benchmarks for DataView set methods * add checks and tests to make sure offset is greater than 0	12 years ago
Ben Noordhuis	5664dd2fc1	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.	12 years ago
isaacs	6c5356bfe2	Revert "buffer: allocate memory with mmap()" Also Revert "buffer: use MAP_ANON, fix OS X build" This reverts commit `ddb15603e7`. This reverts commit `2433ec8276`.	12 years ago
Ben Noordhuis	2433ec8276	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.	12 years ago

Ben Noordhuis	8c02f9b7c8	buffer: throw from constructor if length > kMaxLength Throw, don't abort. `new Buffer(0x3fffffff + 1)` used to bring down the process with the following error message: FATAL ERROR: v8::Object::SetIndexedPropertiesToExternalArrayData() length exceeds max acceptable value Fixes #2280.	13 years ago
Ben Noordhuis	74a8215a86	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 the potential stability issues and intrusive changes to the code base that first-class support for isolates requires. Hence, this commit backs out all isolates-related changes. Good bye, isolates. We hardly knew ye.	13 years ago

Stéphan Kochen	dd52737476	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 up. Now, the constructor takes the wrappee as a parameter.	14 years ago
