    buffer: remove float write range checks

    trevnorris committed with bnoordhuis
    Removed range checks when writing float values, and removed a few
    includes and defines. Also updated api docs to reflect that invalid 32
    bit float is an unspecified behavior.

    buffer: reject negative SlowBuffer offsets

    bnoordhuis committed
    Reject negative offsets in SlowBuffer::MakeFastBuffer(), it allows
    the creation of buffers that point to arbitrary addresses.
    Reported by Trevor Norris.

    buffer: floating point read/write improvements

    trevnorris committed with isaacs
    * 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
    * 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

    buffer: speed up base64 encoding by 20%

    bnoordhuis committed
    Remove a lot of branches from the inner loop. Speeds up buf.toString('base64')
    by about 20%.

    buffer: allocate memory with mmap()

    bnoordhuis committed
    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.

    buffer: report proper retained size in profiler

    bnoordhuis committed
    Make buffers report the proper retained size in heap snapshots.
    Before this commit, Buffer objects would show up in the heap profiler as being
    only a few hundred bytes large, even if the actual buffer was many megabytes.

    Avoiding unnecessary ToString() calls

    buffer: throw from constructor if length > kMaxLength

    bnoordhuis committed
    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.

    Revert support for isolates.

    bnoordhuis committed
    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.

    buffers: fix intermittent out of bounds error

    bnoordhuis committed
    The base64 decoder would intermittently throw an out-of-bounds exception when
    the buffer in `buf.write('', 'base64')` was a zero-sized buffer located at the
    end of the slab.
    Fixes #2657.

    buffers: honor length argument in base64 decoder

    bnoordhuis committed
    Honor the length argument in `buf.write(s, 0, buf.length, 'base64')`. Before
    this commit, the length argument was ignored. The decoder would keep writing
    until it hit the end of the buffer. Since most buffers in Node are slices of
    a parent buffer (the slab), this bug would overwrite the content of adjacent
    The bug is trivially demonstrated with the following test case:
        var assert = require('assert');
        var a = Buffer(3);
        var b = Buffer('xxx');
        a.write('aaaaaaaa', 'base64');
        assert.equal(b.toString(), 'xxx');
    This commit coincidentally also fixes a bug where Buffer._charsWritten was not
    updated for zero length buffers.
