Subject: add_realloc.patch
|
|
|
|
Blink overrides ArrayBuffer's allocator with its own one, while Node simply
|
|
uses malloc and free, so we need to use v8's allocator in Node. As part of the
|
|
10.6.0 upgrade, we needed to make SerializerDelegate accept an allocator
|
|
argument in its constructor, and override ReallocateBufferMemory and
|
|
FreeBufferMemory to use the allocator. We cannot simply allocate and then memcpy
|
|
when we override ReallocateBufferMemory, so we therefore need to implement
|
|
Realloc on the v8 side.
