* In order to prevent ArrayBuffers from getting garbage collected by V8, we used to store a v8::Persistent<ArrayBuffer> in a map. This patch introduces a custom ArrayBuffer allocator which doesn't use Persistent handles, but instead stores a pointer to the actual ArrayBuffer data alongside with a reference count. Since creating Persistent handles has quite a bit of overhead, this change significantly increases performance. Various HTTP server benchmarks report about 5-10% more requests per second than before. * Previously the Persistent handle that prevented garbage collection had to be released manually, and this wasn't always done, which was causing memory leaks. This has been resolved by introducing a new `PinnedBuf` type in both Rust and C++ that automatically re-enables garbage collection when it goes out of scope. * Zero-copy buffers are now correctly wrapped in an Option if there is a possibility that they're not present. This clears up a correctness issue where we were creating zero-length slices from a null pointer, which is against the rules. |
