Comprehensive Rust 🦀

This repository has the source code for Comprehensive Rust 🦀, a multi-day Rust course developed by the Android team. The course covers all aspects of Rust, from basic syntax to generics and error handling. It also includes deep dives on Android, Chromium, bare-metal, and concurrency.

Read the course at https://google.github.io/comprehensive-rust/.

Course Format and Target Audience

The course is used internally at Google when teaching Rust to experienced software engineers. They typically have a background in C++ or Java.

The course is taught in a classroom setting and we hope it will be useful for others who want to teach Rust to their team. The course will be less useful for self-study since you miss out on the discussions happening in the classroom. You don’t see the questions and answers and you don’t see the compiler errors we trigger when going through the code samples. We hope to improve on this via speaker notes and by publishing videos.

uBlock Origin (uBO)

Browser	Install from …	Status
	Firefox Add-ons	uBO works best on Firefox
	Edge Add-ons
	Opera Add-ons
	Chrome Web Store	About Google Chrome’s “This extension may soon no longer be supported” End of support on Chrome 139
	Thunderbird Add-ons	No longer updated and stuck at 1.49.2

uBlock Origin (uBO) is a CPU and memory-efficient wide-spectrum content blocker for Chromium and Firefox. It blocks ads, trackers, coin miners, popups, annoying anti-blockers, malware sites, etc., by default using EasyList, EasyPrivacy, Peter Lowe’s Blocklist, Online Malicious URL Blocklist, and uBO filter lists. There are many other lists available to block even more. Hosts files are also supported. uBO uses the EasyList filter syntax and extends the syntax to work with custom rules and filters.

You may easily unselect any preselected filter lists if you think uBO blocks too much. For reference, Adblock Plus installs with only EasyList, ABP filters, and Acceptable Ads enabled by default.

It is important to note that using a blocker is NOT theft. Do not fall for this creepy idea. The ultimate logical consequence of blocking = theft is the criminalization of the inalienable right to privacy.

Ads, “unintrusive” or not, are just the visible portion of the privacy-invading means entering your browser when you visit most sites. uBO’s primary goal is to help users neutralize these privacy-invading methods in a way that welcomes those users who do not wish to use more technical means.

Documentation

Thorium

Chromium fork for linux named after radioactive element No. 90. Windows/MacOS/RasPi/Android/Other builds see below.

Always built with the latest stable version of Chromium.
Intended to behave like and have the featureset of Google Chrome, with differences/patches/enhancements listed below.
Includes Widevine, All Codecs, Chrome Plugins, as well as thinLTO, CFlag, LDFlag, LLVM Loop, and PGO compiler optimizations. It is built with SSE4, AVX, and AES, so it won’t launch on CPU’s below 2nd gen Core or AMD FX, but benefits from Advanced Vector EXtensions. If your CPU lacks AVX, you can use builds from the Thorium SSE3 repo.

Other Builds

– Windows builds are here > Thorium Win
– AVX2 Builds for Windows and Linux > Thorium AVX2
– MacOS (M1 and X64) builds are located at > Thorium Mac
– Android (arm32 & arm64) builds are located at > Thorium Android I might also occasionally post x86 builds.
– Raspberry Pi builds are located at > Thorium Raspi For the Pi 3B/3B+ and Pi 4/400.
– Special builds are located at > Thorium Special You can find SSE3 builds for CPUs without AVX here.
– Thorium Website with deb repo for auto-updating on Linux > https://thorium.rocks/
– NEW: Windows 7 / 8 / 8.1 / Server 2012 builds in > Thorium Win7

FEATURES & DIFFERENCES BETWEEN CHROMIUM AND THORIUM

Various compiler flags that improve performance and target AVX CPU’s (read PATCHES.md)

Experimental MPEG-DASH support.

HEVC/H.265 support on Linux and Windows.

JPEG XL Image File Format support restored and turned on by default.

FTP URL support restored and enabled by default.

Enable Live Caption (SODA) on all builds.

Experimental PDF annotation support (called “Ink” on ChromiumOS). # DISABLED FOR NOW BECAUSE OF CRASHES.

Patches from Debian including font rendering patch, VAAPI Patch, Intel HD support patch, native notifications patch, title bar patch, and… the VDPAU Patch!! (Rejoice Nvidia users)

Linux audio sandbox patch.

DoH (DNS over HTTPS) patches from Bromite.

Enable Do Not Track by default patch from Vanadium.

Show full URLs including trailing slashes in address bar by default.

Disable FLOC patch.

Adds DuckDuckGo, Brave Search, Ecosia, Ask.com, and Yandex.com in US and other locales, along with the normal search engines.

Always use the local NTP (New Tab Page) regardless of search engine.

Fix icons when distilling page content in Reader Mode.

Enable new Menu UI when right clicking the Reload button. (Adds ‘Normal Reload’, ‘Hard Reload’, and ‘Clear Cache and Hard Reload’)

Home button, Chrome Labs button, and Bookmarks bar shown by default.

Prefetch settings updated to respect privacy.

Patches for GN and chrome_sandbox when building.

Remove the addition of the Chrome APT sources.list during installation.

Widevine CDM Patch for Linux.

GTK auto dark mode patch

Various new flags either developed from scratch, or added from Ungoogled Chromium. See PATCHES.md

Enable Parallel Downloading by Default.

Inclusion of pak a utility for packing and unpacking the *.pak files in Thorium or any other Chromium based browser.

Logo and Branding/Naming changed to the Thorium logo, Thorium name, and “Alex313031” being appended to “The Chromium Authors” in credits, etc.

.desktop file includes useful cmdline flags that enable experimental or useful features. (See PATCHES.md)

Includes installer patches and files to include ChromeDriver and thorium_shell (content_shell), with a .desktop file being provided for thorium_shell (named thorium-shell.desktop and shows in desktop environments as Thorium Content Shell). These are also included in the Windows releases, but it doesn’t make a shorcut, although a .png and .ico is in the install directory for you to make your own shortcut with an icon. You can also run content_shell with the command thorium-shell (custom wrapper for it, located in /usr/bin/). You can run ChromeDriver at /usr/bin/chromedriver or chromedriver.exe on Windows. Also, patches for abseil library and mini_installer when building with AVX on Windows.

Right clicking the launcher after install gives three additional desktop actions, one to open thorium-shell, another to open in Safe Mode which disables any flags one has set in chrome://flags until the next launch, and lastly to open in Dark Mode which appends the –force-dark-mode flag.

For more info, read the PATCHES.md file.
Known bugs are in the BUGS.md file.

🎭 Playwright

Documentation | API reference

Playwright is a framework for Web Testing and Automation. It allows testing Chromium, Firefox and WebKit with a single API. Playwright is built to enable cross-browser web automation that is ever-green, capable, reliable and fast.

	Linux	macOS	Windows
Chromium 138.0.7204.35	:white_check_mark:	:white_check_mark:	:white_check_mark:
WebKit 18.5	:white_check_mark:	:white_check_mark:	:white_check_mark:
Firefox 139.0	:white_check_mark:	:white_check_mark:	:white_check_mark:

Headless execution is supported for all browsers on all platforms. Check out system requirements for details.

Looking for Playwright for Python, .NET, or Java?

Installation

Playwright has its own test runner for end-to-end tests, we call it Playwright Test.

Using init command

The easiest way to get started with Playwright Test is to run the init command.

# Run from your project's root directory
npm init playwright@latest
# Or create a new project
npm init playwright@latest new-project

This will create a configuration file, optionally add examples, a GitHub Action workflow and a first test example.spec.ts. You can now jump directly to writing assertions section.

Manually

Add dependency and install browsers.

1
2
3

npm i -D @playwright/test
# install supported browsers
npx playwright install

You can optionally install only selected browsers, see install browsers for more details. Or you can install no browsers at all and use existing browser channels.

Capabilities

Resilient • No flaky tests

Auto-wait. Playwright waits for elements to be actionable prior to performing actions. It also has a rich set of introspection events. The combination of the two eliminates the need for artificial timeouts - a primary cause of flaky tests.

Web-first assertions. Playwright assertions are created specifically for the dynamic web. Checks are automatically retried until the necessary conditions are met.

Tracing. Configure test retry strategy, capture execution trace, videos and screenshots to eliminate flakes.

No trade-offs • No limits

Browsers run web content belonging to different origins in different processes. Playwright is aligned with the architecture of the modern browsers and runs tests out-of-process. This makes Playwright free of the typical in-process test runner limitations.

Multiple everything. Test scenarios that span multiple tabs, multiple origins and multiple users. Create scenarios with different contexts for different users and run them against your server, all in one test.

Trusted events. Hover elements, interact with dynamic controls and produce trusted events. Playwright uses real browser input pipeline indistinguishable from the real user.

Test frames, pierce Shadow DOM. Playwright selectors pierce shadow DOM and allow entering frames seamlessly.

Full isolation • Fast execution

Browser contexts. Playwright creates a browser context for each test. Browser context is equivalent to a brand new browser profile. This delivers full test isolation with zero overhead. Creating a new browser context only takes a handful of milliseconds.

Log in once. Save the authentication state of the context and reuse it in all the tests. This bypasses repetitive log-in operations in each test, yet delivers full isolation of independent tests.

Powerful Tooling

Codegen. Generate tests by recording your actions. Save them into any language.

Playwright inspector. Inspect page, generate selectors, step through the test execution, see click points and explore execution logs.

Trace Viewer. Capture all the information to investigate the test failure. Playwright trace contains test execution screencast, live DOM snapshots, action explorer, test source and many more.

Looking for Playwright for TypeScript, JavaScript, Python, .NET, or Java?

Examples

To learn how to run these Playwright Test examples, check out our getting started docs.

Page screenshot

This code snippet navigates to Playwright homepage and saves a screenshot.

import { test } from '@playwright/test';

test('Page Screenshot', async ({ page }) => {
  await page.goto('https://playwright.dev/');
  await page.screenshot({ path: `example.png` });
});

Mobile and geolocation

This snippet emulates Mobile Safari on a device at given geolocation, navigates to maps.google.com, performs the action and takes a screenshot.

import { test, devices } from '@playwright/test';

test.use({
  ...devices['iPhone 13 Pro'],
  locale: 'en-US',
  geolocation: { longitude: 12.492507, latitude: 41.889938 },
  permissions: ['geolocation'],
})

test('Mobile and geolocation', async ({ page }) => {
  await page.goto('https://maps.google.com');
  await page.getByText('Your location').click();
  await page.waitForRequest(/.*preview\/pwa/);
  await page.screenshot({ path: 'colosseum-iphone.png' });
});

Evaluate in browser context

This code snippet navigates to example.com, and executes a script in the page context.

import { test } from '@playwright/test';

test('Evaluate in browser context', async ({ page }) => {
  await page.goto('https://www.example.com/');
  const dimensions = await page.evaluate(() => {
    return {
      width: document.documentElement.clientWidth,
      height: document.documentElement.clientHeight,
      deviceScaleFactor: window.devicePixelRatio
    }
  });
  console.log(dimensions);
});

Intercept network requests

This code snippet sets up request routing for a page to log all network requests.

import { test } from '@playwright/test';

test('Intercept network requests', async ({ page }) => {
  // Log and continue all network requests
  await page.route('**', route => {
    console.log(route.request().url());
    route.continue();
  });
  await page.goto('http://todomvc.com');
});
