Eventmachine
EventMachine ist ein auf dem Reactor-Pattern basierendes Netzwerk-Framework für Ruby, das eine asynchrone I/O-Bibliothek für nicht-blockierende Netzwerk- und Dateioperationen bereitstellt. Es fungiert als Framework für Netzwerkserver, um skalierbare TCP- und UDP-Server sowie Clients zu erstellen, die mehrere gleichzeitige Anfragen verarbeiten.
Das Framework implementiert ein Concurrency-Modell, das Netzwerkereignisse über eine Single-Threaded-Event-Loop an registrierte Handler verteilt. Dieser Ansatz ermöglicht die Verwaltung hochgradig gleichzeitiger Netzwerkverbindungen ohne den Overhead von Multi-Threading.
Die Bibliothek deckt die Entwicklung ereignisgesteuerter Server, asynchroner Netzwerk-Clients und Netzwerk-Proxy-Implementierungen ab. Zudem bietet sie Funktionen zur Überwachung von Dateien und Netzwerken, um bei bestimmten Ereignissen Aktionen auszulösen.
Features
- Ruby Implementations - Provides a reactor-pattern network framework for Ruby to handle high-concurrency connections using a non-blocking event loop.
- Reactor Pattern Event Loops - Implements a single-threaded event loop that waits for network events and dispatches them to registered callbacks.
- Asynchronous Network Clients - Provides libraries and interfaces for performing non-blocking, multi-handle network data transfers as a client.
- IO Multiplexing - Uses system calls like select or epoll to monitor multiple network sockets on a single thread.
- Event-Driven Networking - Handles network requests and system events asynchronously using a high-performance runtime model for concurrency.
- Reactor Pattern Network Servers - Provides a framework for building scalable network servers using the reactor pattern and non-blocking I/O.
- Reactor Patterns - Implements an event-driven loop that dispatches incoming network events to registered handlers using a single-threaded reactor.
- Event-Driven Server Frameworks - Provides a framework for building applications that handle concurrent connections and event-driven communication.
- TCP Server Frameworks - Provides the core infrastructure for building high-performance TCP and UDP servers.
- Asynchronous I/O Libraries - Provides a non-blocking interface for system I/O operations via a reactor event loop.
- Single-Threaded Execution Models - Handles thousands of simultaneous connections on one thread to eliminate locking and context switching overhead.
- Event-Driven I/O - Manages network connections and data transfer using an asynchronous I/O framework with event notification loops.
- Asynchronous Network Callbacks - Triggers Ruby blocks of code immediately in response to network I/O events to maintain non-blocking flows.
- Ruby Bindings - Binds high-performance network logic written in C to Ruby for faster event processing.
- Traffic Routing Proxies - Routes network traffic through intermediary servers to manage connection paths with custom logic.
- Network Proxies - Acts as an intermediary between clients and servers to manage traffic and connection routing.
- Proxy Server Implementations - Implements proxy server protocols and logic to route traffic between clients and servers.
- Concurrency and Parallelism - Library for event-driven I/O and lightweight concurrency.
- Ruby Frameworks and Tools - Event-driven library for Ruby.
