R binding for NNG (Nanomsg Next Gen), a successor to ZeroMQ. A toolkit for messaging, concurrency and the web. High-performance socket messaging over in-process, IPC, TCP, WebSocket and secure TLS transports implements 'Scalability Protocols', a standard for common communications patterns including publish/subscribe, request/reply and survey. A threaded concurrency framework with intuitive 'aio' objects that resolve automatically upon completion of asynchronous operations, and synchronisation primitives that allow R to wait on events signalled by concurrent threads. A unified HTTP server hosting REST endpoints, WebSocket connections and streaming on a single port, with a built-in HTTP client.
Changes in 1.10.3
New Features
- Implements the
_server.ymlstandard for R server frameworks, allowing deployment platforms to launch nanonext HTTP/WebSocket servers without knowledge of the package internals (thanks @JosiahParry, #349).
Updates
- Fixes an erroring unserialization hook (
ufunc) halting non-interactive R processes; the object now unserializes as an 'errorValue' (#356). - Our configure script now requires a system 'libmbedtls' 3.x, falling back to the bundled build when an incompatible version is detected (#350).
- Our configure script now checks a detected system 'libnng' for working TLS support, falling back to the bundled build otherwise (#353).
- Fixes a
ncurl()process crash when following a redirect to an unsupported URL (#351). - Fixes a blocking TLS
dial()failure, e.g. connection refused, causing a process crash (#346). stop_aio()no longer resets the R interrupt state.http_server()now normalizes the request URI before it reaches a handler. For example, a request for/../../outside.txtarrives as/outside.txt. This normalization applies to all handler types: static file and directory handlers, and Rhandler()callbacks.- Updates the bundled 'libnng' to v1.12.3, which includes upstream security fixes that:
- block path traversal attacks at the HTTP server,
Show all changes in 1.10.3Hide the rest of the changes in 1.10.3
- prevent a crash of the HTTP client when it receives a malformed chunked message,
- reject unreasonably large message sizes, and
- limit memory use for websocket connections that receive many small frames.
- Increases the minimum supported system
libnngversion to >= v1.12.3.
