bors-servo f5e97ef1b5 Auto merge of #7165 - g-k:refactor-debug-options, r=ms2ger
Fail on unrecognized debug option

Refs: https://github.com/servo/servo/issues/7142

Ran some basic functional tests:

```
 $ ./mach run -d -Z bubble-widths,disable-canvas-aa,trace-layout tests/ref/blur_ref.html
 $ ./mach run -d -Z help
Usage: /Users/greg/servo/target/debug/servo debug option,[options,...]
	where options include

Options:
	bubble-widths                       Bubble intrinsic widths separately like other engines.
	disable-text-aa                     Disable antialiasing of rendered text.
	disable-canvas-aa                   Disable antialiasing on the HTML canvas element.
	dump-flow-tree                      Print the flow tree after each layout.

	trace-layout                        Write layout trace to an external file for debugging.
	validate-display-list-geometry      Display an error when display list geometry escapes overflow region.
	disable-share-style-cache           Disable the style sharing cache.
	parallel-display-list-building      Build display lists in parallel.
	replace-surrogates                  Replace unpaires surrogates in DOM strings with U+FFFD. See https://github.com/servo/servo/issues/6564
	gc-profile                          Log GC passes and their durations.

$ ./mach run -d -Z blah
error: unrecognized debug option: blah
Servo exited with return value 1
```

Didn't check that setting debug flags actually did anything.
Haven't written much Rust so this feels more verbose than necessary.
Added `disable-canvas-aa` to debug options help.

Should DebugOptions struct derive Clone like Opts does?

The Servo Parallel Browser Project

Servo is a prototype web browser engine written in the Rust language. It is currently developed on 64bit OS X, 64bit Linux, Android, and Gonk (Firefox OS).

Servo welcomes contribution from everyone. See CONTRIBUTING.md for help getting started.

Prerequisites

On OS X (homebrew):

brew install automake pkg-config python cmake
pip install virtualenv

On OS X (MacPorts):

sudo port install python27 py27-virtualenv cmake

On Debian-based Linuxes:

sudo apt-get install curl freeglut3-dev \
    libfreetype6-dev libgl1-mesa-dri libglib2.0-dev xorg-dev \
    gperf g++ cmake python-virtualenv \
    libssl-dev libbz2-dev libosmesa6-dev libxmu6 libxmu-dev libglu1-mesa-dev

On Fedora:

sudo dnf install curl freeglut-devel libtool gcc-c++ libXi-devel \
    freetype-devel mesa-libGL-devel glib2-devel libX11-devel libXrandr-devel gperf \
    fontconfig-devel cabextract ttmkfdir python python-virtualenv expat-devel \
    rpm-build openssl-devel cmake bzip2-devel libXcursor-devel libXmu-devel mesa-libOSMesa-devel

On Arch Linux:

sudo pacman -S --needed base-devel git python2 python2-virtualenv mesa cmake bzip2 libxmu

Cross-compilation for Android:

Pre-installed Android tools are needed. See wiki for details

Using Virtualbox:

If you're running servo on a guest machine, make sure 3D Acceleration is switched off (#5643)

The Rust compiler

Servo's build system automatically downloads a snapshot Rust compiler to build itself. This is normally a specific revision of Rust upstream, but sometimes has a backported patch or two. If you'd like to know the snapshot revision of Rust which we use, see rust-snapshot-hash.

Building

Servo is built with Cargo, the Rust package manager. We also use Mozilla's Mach tools to orchestrate the build and other tasks.

Normal build

To build Servo in development mode. This is useful for development, but the resulting binary is very slow.

git clone https://github.com/servo/servo
cd servo
./mach build --dev
./mach run tests/html/about-mozilla.html

For benchmarking, performance testing, or real-world use, add the --release flag to create an optimized build:

./mach build --release
./mach run --release tests/html/about-mozilla.html

Building for Android target

git clone https://github.com/servo/servo
cd servo
ANDROID_TOOLCHAIN=/path/to/toolchain ANDROID_NDK=/path/to/ndk PATH=$PATH:/path/to/toolchain/bin ./mach build --android
cd ports/android
ANDROID_SDK=/path/to/sdk make install

Rather than setting the ANDROID_* environment variables every time, you can also create a .servobuild file and then edit it to contain the correct paths to the Android SDK/NDK tools:

cp servobuild.example .servobuild
# edit .servobuild

Running

Use ./mach run [url] to run Servo.

Commandline Arguments

  • -p INTERVAL turns on the profiler and dumps info to the console every INTERVAL seconds
  • -s SIZE sets the tile size for painting; defaults to 512
  • -z disables all graphical output; useful for running JS / layout tests

Keyboard Shortcuts

  • Ctrl-L opens a dialog to browse to a new URL (Mac only currently)
  • Ctrl-- zooms out
  • Ctrl-= zooms in
  • Backspace goes backwards in the history
  • Shift-Backspace goes forwards in the history
  • Esc exits servo

Developing

There are lots of mach commands you can use. You can list them with ./mach --help.
