B6: RenderProcessHost: Lifecycle and Architecture Management

The provided documents outline the essential functions of the RenderProcessHost (RPH), a crucial component within Chromium's multi-process architecture that resides in the browser process to manage a single associated renderer process. This host object serves as the browser-side anchor for all interactions, primarily by establishing and facilitating Inter-Process Communication (IPC) channels for message transfer and handling. The RPH is responsible for the complete process lifecycle management, overseeing the launch, graceful shutdown, or abrupt termination of the renderer, while also managing crash detection. Furthermore, it enforces critical security and sandboxing policies by filtering sensitive actions like unauthorized URL requests and maintaining site isolation locks to protect the browser. Sophisticated mechanisms for resource management allow the RPH to control process priority, backgrounding processes when hidden, and manage ref counts to keep active workers running. It also tracks the mapping of internal frames and views, ensuring that incoming IPC messages are correctly routed to the appropriate target within the browser process.
