Trevor Norris	d69a26b965	buffer: check logic simplification Checks have been simplified and optimized for most-used cases. Calling Buffer with another Buffer as the subject will now use the SlowBuffer Copy method instead of the for loop. No need to call for value coercion, just place the ternary inline.	12 years ago
Ben Noordhuis	3f7e88a852	buffer: accept negative indices in Buffer#slice() A negative start or end parameter now indexes from the end of the buffer. More in line with String#slice() and ArrayBuffer#slice().	12 years ago
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	65249ccd9b	buffer: slow buffer copy compatibility fix Fix issue where SlowBuffers couldn't be passed as target to Buffer copy(). Also included checks to see if Argument parameters are defined before assigning their values. This offered ~3x's performance gain. Backport of `16bbecc` from master branch. Closes #4633.	12 years ago
Trevor Norris	cbe3941db9	buffer: error and misc cleanup Changed types of errors thrown to be more indicative of what the error represents. Also removed a few unnecessary uses of the v8 fully quantified typename.	12 years ago
Trevor Norris	49175e6ae2	buffer: clean up copy() asserts and tests Argument checks were simplified by setting all undefined/NaN or out of bounds values equal to their defaults. Also copy() tests had a flaw that each buffer had the same bit pattern at the same offset. So even if the copy failed, the bit-by-bit comparison would have still been true. This was fixed by filling each buffer with a unique value before copy operations.	12 years ago

Ben Noordhuis	498200b87c	buffer: reject negative SlowBuffer offsets Reject negative offsets in SlowBuffer::MakeFastBuffer(), it allows the creation of buffers that point to arbitrary addresses. Reported by Trevor Norris.	12 years ago
isaacs	b9ffc537e6	lint: Prefer double-quotes over single	12 years ago
Trevor Norris	7393740c7b	buffer: improve read/write speed with assert Improved assert check order of execution and added additional checks on parameters to ensure no bad values make it through (e.g. negative offset values).	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

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
Trevor Norris	6772308883	buffer: Don't double-negate numeric buffer arg Fix #4331 Using double negate forces values into 32bit space. Because of this Math.ceil needs to be used. Since NaN comparisons are always false, use that to our advantage to return 0 if it is. Also added two tests to verify the changes.	12 years ago
Trevor Norris	13c5db9771	buffer: remove duplicate assertion tests Many assertion tests are duplicated in buffer.js. These few could be easily removed and still have all tests pass.	12 years ago
Ricky Ng-Adam	8bd4590a31	buffer: include encoding value in exception when invalid Encoding failures can be somewhat confusing, especially when they are due to control flow frameworks auto-filling parameters from the previous step output values to functions (such as toString and write) that developers don't expect to take an encoding parameter. By outputting the value as part of the message, should make it easier to track down these sort of bugs.	12 years ago

Nathan Rajlich	38542f76a9	buffer: make SlowBuffer inherit from Buffer This frees us from manually having to copy over functions to SlowBuffer's prototype (which has bitten us multiple times in the past). As an added bonus, the `inspect()` function is now shared between Buffer and SlowBuffer, removing some duplicate code. Closes #3228.	13 years ago
