LLViewerApp

Objectives

• Improve the stability and maintainability of the Second Life Viewer code by cleaning up the initialization and main loop code
• Move the main loop to a separate thread so that infinite loops can be detected and debugged

Tasks

Phase 1

LLViewerApp

• Create a LLViewerApp class based on LLAppb
• Move class initialization and parameter parsing to LLViewerApp
• Move all error handling to LLViewerApp (errors set a flag and sleep, LLViewerApp generates the exception)
• Move all debug/info/warning/error text printing to LLViewerApp
  • Print text to a buffer instead of stdio
  • Send the buffer to stdio in LLViewerApp loop

LLViewerThread

• Create a LLViewerThread class based on LLThread
• Move the main loop into LLViewerThread

Eliminate viewer.cpp

• Create proper C++ abstractions for any remaining code in viewer.cpp

Watchdog

• Add a 'watchdog' to LLViewerApp to detect infinite loops and trigger a crash
• Ensure that the crash handler generates proper stack information for LLViewerThread

Phase 2

LLViewerLogin

• Abstract the login sequence into a class

Eliminate startup.cpp

• Create proper C++ abstractions for startup using LLViewerLogin

Lightweight Client

• Create a client that logs in to Second Life without running the 3D render pipeline
