2018-02-14src: refactor WriteWrap and ShutdownWrapsAnna Henningsen
Encapsulate stream requests more: - `WriteWrap` and `ShutdownWrap` classes are now tailored to the streams on which they are used. In particular, for most streams these are now plain `AsyncWrap`s and do not carry the overhead of unused libuv request data. - Provide generic `Write()` and `Shutdown()` methods that wrap around the actual implementations, and make *usage* of streams easier, rather than implementing; for example, wrap objects don’t need to be provided by callers anymore. - Use `EmitAfterWrite()` and `EmitAfterShutdown()` handlers to call the corresponding JS handlers, rather than always trying to call them. This makes usage of streams by other C++ code easier and leaner. Also fix up some tests that were previously not actually testing asynchronicity when the comments indicated that they would.

2018-02-01fs: partition readFile against pool exhaustionJamie Davis
Problem: Node implements fs.readFile as: - a call to stat, then - a C++ -> libuv request to read the entire file using the stat size Why is this bad? The effect is to place on the libuv threadpool a potentially-large read request, occupying the libuv thread until it completes. While readFile certainly requires buffering the entire file contents, it can partition the read into smaller buffers (as is done on other read paths) along the way to avoid threadpool exhaustion. If the file is relatively large or stored on a slow medium, reading the entire file in one shot seems particularly harmful, and presents a possible DoS vector. Solution: Partition the read into multiple smaller requests. Considerations: 1. Correctness I don't think partitioning the read like this raises any additional risk of read-write races on the FS. If the application is concurrently readFile'ing and modifying the file, it will already see funny behavior. Though libuv uses preadv where available, this doesn't guarantee read atomicity in the presence of concurrent writes. 2. Performance Downside: Partitioning means that a single large readFile will require into many "out and back" requests to libuv, introducing overhead. Upside: In between each "out and back", other work pending on the threadpool can take a turn. In short, although partitioning will slow down a large request, it will lead to better throughput if the threadpool is handling more than one type of request.
