ash

Ash is the “Aura Shell”, the window manager and system UI for Chrome OS.
Ash uses the views UI toolkit (e.g. views::View, views::Widget, etc.) backed
by the aura native widget and layer implementations.
Ash sits below chrome in the dependency graph (i.e. it cannot depend on code
in //chrome). For historical reasons, ash has multiple dependency levels

base

About //base:
Chromium is a very mature project. Most things that are generally useful are
already here and things not here aren’t generally useful.
The bar for adding stuff to base is that it must have demonstrated wide
applicability. Prefer to add things closer to where they’re used (i.e. “not
base”), and pull into base only when needed. In a project our size,
sometimes even duplication is OK and inevitable.

build

//build contains:

• Core GN templates and configuration
• Core Python build scripts
  Since this directory is DEPS’ed in by some other repositories (webrtc, pdfium,
  v8, etc), it should be kept as self-contained as possible by not referring
  to files outside of it. Some exceptions exist (//testing, select
  //third_party subdirectories), but new dependencies tend to break these other
  projects, and so should be avoided.

build_overrides

This directory is used to allow different products to customize settings
for repos that are DEPS’ed in or shared.
For example: V8 could be built on its own (in a “standalone” configuration),
and it could be built as part of Chromium. V8 might define a top-level
target, //v8:d8 (a simple executable), that should only be built in the
standalone configuration. To figure out whether or not it should be
in a standalone configuration, v8 can create a file, build_overrides/v8.gni,
that contains a variable, build_standalone_d8 = true.
and import it (as import(“//build_overrides/v8.gni”) from its top-level
BUILD.gn file.
Chromium, on the other hand, might not need to build d8, and so it would
create its own build_overrides/v8.gni file, and in it set
build_standalone_d8 = false.
The two files should define the same set of variables, but the values can
vary as appropriate to the needs of the two different builds.

cc

This directory contains a compositor, used in both the renderer and the
browser. In the renderer, Blink is the client. In the browser, both
ui and Android browser compositor are the clients.
The public API of the compositor is LayerTreeHost and Layer and its
derived types. Embedders create a LayerTreeHost (single, multithreaded,
or synchronous) and then attach a tree of Layers to it.

chrome

This directory contains the open source, application layer of Google Chrome.
Unlike other parts of Chromium like //content, which provide framework intended
to support multiple products, this directory contains code that is focused on
building specific products with opinionated UX.
Specific products include:

• Chrome desktop browser for Chrome OS, Windows, Mac and Linux
• Chrome mobile browser for Android
• Chrome OS system UI

chromecast

Cast base > cast_features
This file contains tools for checking the feature state of all of the features
which affect Cast products. Cast features build upon
the Chrome feature system.
Some aspects of Cast require the feature system to work differently, however,
so some additional logic has been layered on top. Details are available in
comments of the header file.

chromeos

Chrome OS
This directory contains low-level support for Chrome running on Chrome OS.
The Lacros project is in the process of extracting the
browser-functionality into a separate binary. This introduces the following
terminology and rules:

• ash-chrome: The new name of the legacy “chrome” binary. It contains system
  UI and the current/legacy web browser. Code that is only used by ash-chrome
  should eventually be moved to //chromeos/ash, have an _ash suffix in
  the filename, or have a (grand-)parent directory named /ash/.
• lacros-chrome: The name of the new, standalone web-browser binary. Code that
  is only used by lacros-chrome should have a _lacros suffix in the filename,
  or have a (grand-)parent directory named /lacros/.
• crosapi: The term “crosapi” is short for ChromeOS API. Ash-chrome
  implements the API, and lacros-chrome is the only consumer.
• chromeos: The term “chromeos” refers to code that is shared by binaries
  targeting the chromeos platform or using the chromeos toolchain. Code that
  is shared by ash-chrome and lacros-chrome should have a _chromeos suffix in
  the filename, or have a (grand-)parent directory named /chromeos/.

codelabs

Chromium Codelab
See the cpp101/ directory for the Chromium C++ codelab,
including example solutions.
See the threading_and_scheduling/ directory for more elaborate usages of the
threading and scheduling primitives in Chromium.
Motivation：
The goal of this codelab is to introduce new Chromium developers to both the
important design patterns and the style of code they can expect to become
familiar with.
The code in this directory is for documentation purposes only. It is compiled
via the top level BUILD.gn’s gn_all target to make sure it is kept up to date.

components

This directory is meant to house features or subsystems that are used in more
than one part of the Chromium codebase.

Use cases:

• Features that are shared by Chrome on iOS (//ios/chrome) and Chrome on
  other platforms (//chrome).
  • Note: //ios doesn’t depend on //chrome.
• Features that are shared between multiple embedders of content. For example,
  //chrome and //android_webview.
• Features that are shared between Blink and the browser process.

content

Content module
High-level overview
The “content” module is located in src/content, and is the core code needed to
render a page using a multi-process sandboxed browser. It includes all the web
platform features (i.e. HTML5) and GPU acceleration. It does not include Chrome
features, e.g. extensions/autofill/spelling etc.
Motivation
As the Chromium code has grown, features inevitably hooked into the wrong
places, causing layering violations and dependencies that shouldn’t exist. It’s
been hard for developers to figure out what the “best” way is because the APIs
(when they existed) and features were together in the same directory. To avoid
this happening, and to add a clear separation between the core pieces of the
code that render a page using a multi-process browser, consensus was reached to
move the core Chrome code into src/content (content not
chrome 😃 ).
content vs chrome：content should only contain code that is required to implement the web

extensions

This will become a reusable extensions module. It implements the core parts of
Chrome’s extension system, and can be used with any host of the
content module.
Some extensions code that is not Chrome-specific still lives in

mojo

Getting Started With Mojo
To get started using Mojo in Chromium, the fastest path forward will likely be
to read the Mojo sections of the
Intro to Mojo & Services guide.
For more detailed reference material on the most commonly used features of Mojo,
head directly to the bindings documentation for your language
of choice or the more general
mojom Interface Definition Language (IDL)
documentation.
If you’re looking for information on creating and/or connecting to services,
you’re in the wrong place! Mojo does not deal with services, it only facilitates
interface definition, message passing, and other lower-level IPC primitives.
Instead, you should take a look at some of the other available

pdf

//pdf contains the PDF plugin, its Blink-based replacement, as well as PDF
utility functions that leverage PDFium. It can use low-level components that
live below the content layer, as well as other foundational code like
//printing. It should not use //content or anything in //components that
lives above the content layer. Code that lives above the content layer should
live in //components/pdf, or in the embedder. All the code here should run in
sandboxed child processes.

sandbox

Sandbox Library
This directory contains platform-specific sandboxing libraries. Sandboxing is a
technique that can improve the security of an application by separating
untrustworthy code (or code that handles untrustworthy data) and restricting its
privileges and capabilities.
Each platform relies on the operating system’s process primitive to isolate code
into distinct security principals, and platform-specific technologies are used
to implement the privilege reduction. At a high-level:

• mac/ uses the Seatbelt sandbox. See the detailed
  design for more.
• linux/ uses namespaces and Seccomp-BPF. See the detailed
  design for more.
• win/ uses a combination of restricted tokens, distinct job objects,
  alternate desktops, and integrity levels. See the detailed
  design for more.

services

Service Development Guidelines
The top-level //services directory contains the sources, public Mojo interface

designated as Chrome Foundation Services. If you think of Chrome as a
“portable OS,” Chrome Foundation Services can be thought of as the core system
services of that OS.

skia

Skia is a complete 2D graphic library for drawing Text, Geometries, and Images.
The Skia library can be found in //third_party/skia, and full documentation
is available at https://skia.org/
This directory includes low-level chromium utilities for interacting with Skia:

• Build rules for the Skia library
• Configuration of the library (config/SkUserConfig.h)
• Serialization of Skia types (public/mojom)
• Implementations of Skia interfaces for platform behavior, such as fonts and
  memory allocation, as well as other miscellaneous utilities (ext).
  Note that Skia is used directly in many parts of the chromium codebase.
  This directory is only concerned with code layered on Skia that will be reused
  frequently, across multiple chromium components.

sql

SQLite abstraction layer
SQLite for system designers. SQLite is a
relational database management system (RDBMS)
that supports most of SQL.
SQLite is architected as a library that can be embedded in another application,
such as Chrome. SQLite runs in the application’s process, and shares its memory
and other resources. This is similar to embedded databases like
LevelDB and
BerkeleyDB. By contrast, most
popular RDMBSes, like PostgreSQL and
MySQL, are structured as standalone server processes
that accept queries from client processes.

url

Chrome’s URL library
Layers:
There are several conceptual layers in this directory. Going from the lowest
level up, they are:
Parsing:
The url_parse.* files are the parser. This code does no string
transformations. Its only job is to take an input string and split out the
components of the URL as best as it can deduce them, for a given type of URL.
Parsing can never fail, it will take its best guess. This layer does not
have logic for determining the type of URL parsing to apply, that needs to
be applied at a higher layer (the “util” layer below).
Because the parser code is derived (very distantly) from some code in
Mozilla, some of the parser files are in url/third_party/mozilla/.

angle

** ANGLE - Almost Native Graphics Layer Engine**
The goal of ANGLE is to allow users of multiple operating systems to seamlessly run WebGL and other
OpenGL ES content by translating OpenGL ES API calls to one of the hardware-supported APIs available
for that platform. ANGLE currently provides translation from OpenGL ES 2.0, 3.0 and 3.1 to Vulkan,
desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11. Future plans include ES 3.2, translation to
Metal and MacOS, Chrome OS, and Fuchsia support.
Level of OpenGL ES support via backing renderers：

	Direct3D 9	Direct3D 11	Desktop GL	GL ES	Vulkan	Metal
OpenGL ES 2.0	complete	complete	complete	complete	complete	complete
OpenGL ES 3.0		complete	complete	complete	complete	complete
OpenGL ES 3.1		[incomplete][ES31OnD3D]	complete	complete	complete
OpenGL ES 3.2			in progress	in progress	complete
Additionally, OpenGL ES 1.1 is implemented in the front-end using OpenGL ES 3.0 features. This

brotli

### Introduction Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression. The specification of the Brotli Compressed Data Format is defined in [RFC 7932](https://tools.ietf.org/html/rfc7932). Brotli is open-sourced under the MIT License, see the LICENSE file.

chevron

A python implementation of the mustache templating language.
Why chevron?

I’m glad you asked!

chevron is fast

Chevron runs in less than half the time of pystache (Which is not even up to date on the spec).
And in about 70% the time of Stache (A ‘trimmed’ version of mustache, also not spec compliant).

chevron is pep8

The flake8 command is run by travis to ensure consistency.

chromium-variations

Chromium Variations README

Overview

This repository contains various directories, each of which holds a seed.json
file. Each seed.json file contains a variations seed. A variations seed is used
to turn on/off field trials and features in Chromium projects, such as the
Chromium browser.
Changes to this repository will not be accepted.

Seed Files

• single_group_per_study_prefer_existing_behavior/*
  For each study, this seed enables the largest field trial group. If there
  are multiple groups having the same largest size for a given study, prefer a
  group which enables existing behaviour.
• single_group_per_study_prefer_new_behavior/*

dawn

 [](https://matrix.to/#/#webgpu-dawn:matrix.org)

# Dawn, a WebGPU implementation Dawn is an open-source and cross-platform implementation of the [WebGPU](https://webgpu.dev) standard. More precisely it implements [`webgpu.h`](https://github.com/webgpu-native/webgpu-headers/blob/main/webgpu.h) that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium. Dawn provides several WebGPU building blocks: - **WebGPU C/C++ headers** that applications and other building blocks use. - The `webgpu.h` version that Dawn implements.

ipcz

ipcz

Overview

ipcz is a fully cross-platform C library for interprocess communication (IPC)
intended to address two generic problems: routing and data transfer.

Routing

With ipcz, applications create pairs of entangled portals to facilitate
bidirectional communication. These are grouped into collections called
nodes, which typically correspond 1:1 to OS processes.
Nodes may be explicitly connected by an application to establish portal pairs
which span the node boundary.

jni_zero

JNI Zero

A zero-overhead (or better!) middleware for JNI.

Overview

JNI (Java Native Interface) is the mechanism that enables Java code to call
native functions, and native code to call Java functions.

• Native code calls into Java using apis from <jni.h>, which basically mirror
  Java’s reflection APIs.
• Java code calls native functions by declaring body-less functions with the
  native keyword, and then calling them as normal Java functions.
  JNI Zero generates boiler-plate code with the goal of making our code:

1. easier to write,
2. typesafe.
3. more optimizable.
   JNI Zero uses regular expressions to parse .Java files, so don’t do
   anything too fancy. E.g.:

• Classes must be either explicitly imported, or are assumed to be in

libjpeg_turbo

Background

libjpeg-turbo is a JPEG image codec that uses SIMD instructions to accelerate
baseline JPEG compression and decompression on x86, x86-64, Arm, PowerPC, and
MIPS systems, as well as progressive JPEG compression on x86, x86-64, and Arm
systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg,
all else being equal. On other types of systems, libjpeg-turbo can still
outperform libjpeg by a significant amount, by virtue of its highly-optimized
Huffman coding routines. In many cases, the performance of libjpeg-turbo
rivals that of proprietary high-speed JPEG codecs.
libjpeg-turbo implements both the traditional libjpeg API as well as the less
powerful but more straightforward TurboJPEG API. libjpeg-turbo also features
colorspace extensions that allow it to compress from/decompress to 32-bit and
big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java
interface.
libjpeg-turbo was originally based on libjpeg/SIMD, an MMX-accelerated
derivative of libjpeg v6b developed by Miyasaka Masaru. The TigerVNC and

libsrtp

Introduction to libSRTP

This package provides an implementation of the Secure Real-time
Transport Protocol (SRTP), the Universal Security Transform (UST), and
a supporting cryptographic kernel. The SRTP API is documented in include/srtp.h,
and the library is in libsrtp2.a (after compilation).
This document describes libSRTP, the Open Source Secure RTP library
from Cisco Systems, Inc. RTP is the Real-time Transport Protocol, an
IETF standard for the transport of real-time data such as telephony,
audio, and video, defined by RFC 3550.
Secure RTP (SRTP) is an RTP profile for providing confidentiality to RTP data
and authentication to the RTP header and payload. SRTP is an IETF Standard,
defined in RFC 3711, and was developed
in the IETF Audio/Video Transport (AVT) Working Group. This library supports
all of the mandatory features of SRTP, but not all of the optional features. See

pdfium

PDFium

Prerequisites

PDFium uses the same build tooling as Chromium. See the platform-specific
Chromium build instructions to get started, but replace Chromium’s
“Get the code” instructions with PDFium’s.

• Chromium Linux build instructions
• Chromium Mac build instructions
• Chromium Windows build instructions

CPU Architectures supported

The default architecture for Windows, Linux, and Mac is “x64”. On Windows,
“x86” is also supported. GN parameter “target_cpu = "x86"” can be used to
override the default value. If you specify Android build, the default CPU
architecture will be “arm”.
It is expected that there are still some places lurking in the code which will

pffft

Notes on PFFFT

We strongly recommend to read this file before using PFFFT and to always wrap the original C library within a C++ wrapper.
Example of PFFFT wrapper.

Scratch buffer

The caller can optionally provide a scratch buffer. When not provided, VLA is used to provide a thread-safe option.
However, it is recommended to write a C++ wrapper which allocates its own scratch buffer.
Note that the scratch buffer has the same memory alignment requirements of the input and output vectors.

Output layout

PFFFT computes the forward transform with two possible output layouts:

1. ordered
2. unordered

Ordered layout

Calling pffft_transform_ordered produces an array of interleaved real and imaginary parts.
The last Fourier coefficient is purely real and stored in the imaginary part of the DC component (which is also purely real).

Unordered layout

Private Join and Compute

This project contains an implementation of the “Private Join and Compute”
functionality. This functionality allows two users, each holding an input file,
to privately compute the sum of associated values for records that have common
identifiers.
In more detail, suppose a Server has a file containing the following
identifiers:

Ada
Ruby
Brendan
And a Client has a file containing the following identifiers, paired with
associated integer values:

platform-neutral, extensible mechanism for serializing structured data. You
can find protobuf’s documentation on the Google Developers site.
This README file contains protobuf installation instructions. To install
protobuf, you need to install the protocol compiler (used to compile .proto
files) and the protobuf runtime for your chosen programming language.

puffin

Puffin: A deterministic deflate re-compressor (for patching purposes)
Puffin is a deterministic deflate recompressor. It is mainly used for patching
deflate compressed images (zip, gzip, etc.) because patches created from deflate
files/streams are usually large (deflate has a bit-aligned format, hence,
changing one byte in the raw data can cause the entire deflate stream to change
drastically.)
Puffin has two tools (operations): puffdiff and puffpatch (shown
here.) The purpose of puffdiff operation is to create a patch
between a source and a target file with one or both of them having some deflate
streams. This patch is used in the puffpatch operation to generate the target
file from the source file deterministically. The patch itself is created by
bsdiff library (but can be replaced by any other diffing mechanism). But,

rust

Rust third-party code

This directory contains all third-party Rust code, and sometimes thin wrappers
around it for C++ intertop.

Crates.io

Crates that come from crates.io are found in
//third_party/rust/chromium_crates_io, and are all vendored into the
Chromium git repository. They are managed through Cargo rules and with
the gnrt tool. See //docs/rust.md for how to
bring in new third-party libraries or update them.
The GN rules and README.chromium files for these crates are written by
the gnrt tool and should not be edited by hand.

Directory structure

We store GN rules for each third-party crate in a directory of the same name.
Under that directory a folder named based on the crate epoch version is

sqlite

Chromium SQLite.

This is the top folder for Chromium’s SQLite. The
actual SQLite source is not in this repository, but instead cloned into the
src directory from https://chromium.googlesource.com/chromium/deps/sqlite.
The directory structure is as follows. Files common to all third_party projects
(ex. BUILD.GN, OWNERS, LICENSE) are omitted.

• src/ The Chromium fork of SQLite (cloned via top level DEPS file).
• scripts/ Scripts that generate the files in the amalgamations in src/.
• sqlite.h The header used by the rest of Chromium to include SQLite. This
  forwards to src/amalgamation/sqlite3.h
• fuzz/ Google OSS-Fuzz (ClusterFuzz) testing for Chromium’s SQLite build.

Amalgamations

SQLite amalgamations are committed
to the SQLite Chromium repository (in src), but are created by a script that
lives in the Chromium repository. This is because the configuration variables
for building and amalgamation generation are shared.

swiftshader

SwiftShader

Introduction
SwiftShader[^1] is a high-performance CPU-based implementation[^2] of the Vulkan[^3] 1.3 graphics API. Its goal is to provide hardware independence for advanced 3D graphics.

NOTE: The ANGLE project can be used to achieve a layered implementation[^4] of OpenGL ES 3.1 (aka. “SwANGLE”).
Building
SwiftShader libraries can be built for Windows, Linux, and macOS.
Android and Chrome (OS) build environments are also supported.

unrar

Process for rolling new versions of UnRAR

UnRAR is released on the official
site, but Chromium uses a GitHub
mirror for tracking and fuzzing. This
means that at a high level, rolling a new version of UnRAR has the
following steps:

• Update the GitHub repo
• Wait a week for fuzzing on the new version
• Update the chromium repo

Updating the GitHub repo

You’ll need a GitHub account to do this. Create a fork of the GitHub
repo, and clone that fork to your
local machine (replacing $username with your GitHub username):

git clone https://github.com/$username/unrar.git

woff2

This is a README for the font compression reference code. There are several
compression related modules in this repository.
brotli/ contains reference code for the Brotli byte-level compression
algorithm. Note that it is licensed under the MIT license.
src/ contains the C++ code for compressing and decompressing fonts.

Build & Run

This document documents how to run the compression reference code. At this
writing, the code, while it is intended to produce a bytestream that can be
reconstructed into a working font, the reference decompression code is not
done, and the exact format of that bytestream is subject to change.
The build process depends on the g++ compiler.

Build

On a standard Unix-style environment:

zxcvbn-cpp

This is a C++ port of zxcvbn,
an advanced password strength estimation library. For more details on how
zxcvbn works and its advantages, check out
the blog post.
This port is a direct translation of the original CoffeeScript
source. This allows this port to easily stay in sync with the original
source. Additionally, this port uses the same exact test scripts from
the original with the help of emscripten.
This port also provides C, Python, and JS bindings from the same
codebase.
