Hands-On WebAssembly for C++ Programmers - Tracing Execution in WebAssembly

The video tutorial introduces tracing, a feature for inspecting web assembly execution. It explains how to set up tracing in a Pong CPU application, configure a tracing server, and analyze trace data. The tutorial covers memory allocation tracking, event loop reporting, and using the Google Web Tracing Framework. It provides a comprehensive guide to using tracing tools for better code insights.

What is one of the features of tracing in web assembly execution?

• It generates random test cases.

• It provides allocation annotations.

• It allows for real-time debugging.

• It automatically optimizes code.

What is the first step in setting up the tracing API within an application?

• Annotate memory types.

• Start the tracing server.

• Configure the tracing system.

• Include the tracing library.

Which command is used to configure the tracing system in the main loop?

• emscript_trace_start

• emscript_trace_configure

• emscript_trace_init

• emscript_trace_setup

What is required to spin up a tracing server using the Emscripten trace collector?

• Python 3

• Node.js

• Python 2

• Ruby

Which framework can be used for setting up a tracing server?

• Flask

• Django

• Google Web Tracing Framework

• React

What kind of insights can the trace server provide?

• Memory allocation details

• User interface design flaws

• Code syntax errors
