M1504: Implement support for missing XMLHttpRequest APIs

The goal of this project was to implement support for missing less-common features of the XMLHttpRequest API for Servo.

Servo

Servo <ref> https://github.com/servo/servo </ref> is a web browser layout engine written in Rust<ref>https://github.com/rust-lang/rust</ref> and is currently being developed by Mozilla Research. The aim of the project is to create a highly parallel environment that allows for many components be handled by fine-grained, isolated tasks.<ref>https://en.wikipedia.org/wiki/Servo_(layout_engine)</ref>

Rust

Rust is a multi-paradigm, compiled programming language that is a good language for creating highly safe systems. Rust and Servo have a symbiotic relationship as the development of servo has influenced the design of the language.

XMLHttpRequest

"XMLHttpRequest is a definition of an API that provides scripted client functionality for transferring data between a client and a server."<ref>https://xhr.spec.whatwg.org/</ref> XMLHttpRequest provides a way for data to be retrieved from a URL without having to retrieve the entire page. It supports protocols other than HTTP and can be used to retrieve any type of data.<ref>https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest</ref>

Implementation

Initial Steps

The following steps were followed to meet the project requirements as per this github page.

  • compile Servo and ensure that it runs on tests/html/about-mozilla.html
  • uncomment the overrideMimeType API in XMLHttpRequest.webidl, and add a stub method that allows Servo to compile again to xmlhttprequest.rs.
  • run the tests via ./mach test-wpt tests/wpt/web-platform-tests/XMLHttpRequest/ and adjust the expectations for any that now pass (tests/wpt/metadata/XMLHttpRequest/)
  • add new override_charset and override_mime_type fields to the XMLHttpRequest structure
  • implement the overrideMimeType steps described in the specifications
  • update any tests that now pass

Accepted Pull Request

Here is our pull request. In the link you can see all code snippets changed, as well as integration test progression information.
