DBGp Proxy
DBGp Proxy is a debugging protocol proxy port that facilitates communication between Integrated Development Environments (IDEs) and debugging engines. It acts as an intermediary, enabling multiple connections, and streamlining remote or distributed debugging sessions for scripting languages, such as PHP or Python..
DBGp Proxy operates as an intermediate service that routes debugging information between IDE clients and server-side debug engines. It primarily facilitates remote debugging by managing incoming IDE connections to a single debugging engine instance, helping developers efficiently debug applications running externally or on different environments.
DBGp, short for 'Debugger Protocol,' is designed to be language-neutral and standardized, with a focus on facilitating debugging activities like breakpoints, stack inspection, and variable watching. The proxy enhances this by managing multiple, simultaneous debugging connections, typically on port 9001, providing the convenience of multiple IDE sessions while maintaining a singular backend debugger link.
Technically, the proxy listens on TCP port 9001, receiving XML-formatted DBGp protocol messages. It ensures session assignment and message routing while maintaining the protocol's synchronous communication characteristics, which is critical for effective step-through debugging and breakpoint management.
