CSC/ECE 517 Spring 2016/Implement private browsing

Implement Private Browsing

Servo[1] is a prototype web browser engine written in the RUST language. Servo currently does not support the mode where the cookies, login, history and downloads are forgotten after the session ends. The goal of this project is to implement incognito/private browsing feature in Servo.

Introduction

Servo is an experimental web browser layout engine being developed by Mozilla Research. Servo is written in the Rust language, which is also being developed by Mozilla Research. The language is being refined through feedback from Servo development, and writing the Rust compiler itself. Rust is a systems programming language similar to C and C++ in syntax (but semantically very different). The emphasis is on speed, safety, concurrency and control of memory layout.

Implementation

The following steps were followed to meet the project requirements as per this [1].

Step 1

As required we have added the is_private member to the struct IFrameLoadInfo to check if it's a private iframe or not

We are working on implementing the function to set this member based on the mozprivatebrowsing attribute. We are in touch with Josh regarding the same as currently there is no mozprivatebrowsing attribute in the servo project and hence we are trying to understand how it can be implemented. We have written a basic stub for the same which is as below.

Step 2

We have created an enum that holds an isPrivate message containing pipelineId and sender as attributes

The below member has been added to the pipeline struct to check if it's private

Step 2

We are working on implementing the below function to check if the pipeline is private
