The Servo Browser Engine

/html/semantics/embedded-content/the-img-element/naturalWidth-naturalHeight.html The two failures are the cases where the SVG's root element doesn't have an explicit width & height. The issue is related to how resvg handles such cases - we rely on resvg to provide the natural dimensions as the 'viewbox', 'width' and 'height' are not directly exposed in the parsed tree. resvg internally defaults to a width/height of 100x100 (can be overriden via usvg::Options, but doesn't have any effect if viewBox is not present). It is worth noting that all major browsers fail these cases. https://wpt.fyi/results/html/semantics/embedded-content/the-img-element/naturalWidth-naturalHeight.html?label=experimental&label=master&aligned /css/css-flexbox/align-items-007.html /html/rendering/replaced-elements/svg-embedded-sizing/svg-in-img-auto.html /html/rendering/replaced-elements/svg-embedded-sizing/svg-in-img-fixed.html /html/rendering/replaced-elements/svg-embedded-sizing/svg-in-img-percentage.html The failures are related to the issue explained above. In particular, we are currently not distinguing the case where viewBox is present but width, height are not. As resvg doesn't expose that, we use the viewbox values as natural dimentions rather than treating them as absent. /css/css-backgrounds/background-size/vector/tall--contain--height.html Similar to the above the cases this is related to resvg and lack of distinction between SVGs with explicit height & weight. This test has an SVG with 'width' of 8px but only percentage 'height'. resvg takes the missing height from viewbox (1px), so we render this as if the SVG had an intrinsic dimensions of 8x1, scaled by the container's width, but the test expects that the SVG is treated as no natural dimensions. Chrome, Edge and Safari fail this test. https://wpt.fyi/results/css/css-backgrounds/background-size/vector/tall--contain--height.html?label=experimental&label=master&aligned /css/css-backgrounds/background-size/vector/tall--contain--width.html Same reason as above, except with width missing instead of height. Firefox and Safari fail this test. /css/css-backgrounds/background-size/vector/wide--contain--height.html /css/css-backgrounds/background-size/vector/wide--contain--width.html Same reason as the two 'tall--contain--' tests above. /css/css-backgrounds/background-size/vector/zero-height-ratio-5px-auto.html.ini /css/css-backgrounds/background-size/vector/zero-height-ratio-auto-auto.html.ini /css/css-backgrounds/background-size/vector/zero-height-ratio-contain.html.ini /css/css-backgrounds/background-size/vector/zero-height-ratio-cover.html.ini /css/css-backgrounds/background-size/vector/zero-ratio-no-dimensions-5px-auto.html.ini /css/css-backgrounds/background-size/vector/zero-ratio-no-dimensions-auto-5px.html.ini /css/css-backgrounds/background-size/vector/zero-ratio-no-dimensions-auto-auto.html.ini /css/css-backgrounds/background-size/vector/zero-ratio-no-dimensions-contain.html.ini /css/css-backgrounds/background-size/vector/zero-ratio-no-dimensions-cover.html.ini /css/css-backgrounds/background-size/vector/zero-width-ratio-5px-auto.html.ini /css/css-backgrounds/background-size/vector/zero-width-ratio-auto-auto.html.ini /css/css-backgrounds/background-size/vector/zero-width-ratio-contain.html.ini /css/css-backgrounds/background-size/vector/zero-width-ratio-cover.html.ini All these tests assert that an SVG with no height specified and a zero-ratio in the viewBox (either last or second to last component is zero) is not rendered. Since resvg defaults the height and width to 100px, we are not able to distinguish this case. Signed-off-by: Mukilan Thiyagarajan <mukilan@igalia.com> |

The Servo Parallel Browser Engine Project
Servo is a prototype web browser engine written in the Rust language. It is currently developed on 64-bit macOS, 64-bit Linux, 64-bit Windows, 64-bit OpenHarmony, and Android.
Servo welcomes contribution from everyone. Check out The Servo Book to get started, or go to servo.org for news and guides.
Getting started
For more detailed build instructions, see the Servo book under Setting up your environment, Building Servo, Building for Android and Building for OpenHarmony.

.\mach build
Android
- Ensure that the following environment variables are set:

sudo $ANDROID_SDK_ROOT/cmdline-tools/latest/bin/sdkmanager --install \ "build-tools;34.0.0" \ "emulator" \ "ndk;26.2.11394342" \ "platform-tools" \ "platforms;android-33" \ "system-images;android-33;google_apis;x86_64" - Follow the instructions above for the platform you are building on
OpenHarmony
- Follow the instructions above for the platform you are building on to prepare the environment.
- Depending on the target distribution (e.g.
HarmonyOS NEXTvs pureOpenHarmony) the build configuration will differ slightly. - Ensure that the following environment variables are set
DEVECO_SDK_HOME(Required when targetingHarmonyOS NEXT)OHOS_BASE_SDK_HOME(Required when targetingOpenHarmony)OHOS_SDK_NATIVE(e.g.${DEVECO_SDK_HOME}/default/openharmony/nativeor${OHOS_BASE_SDK_HOME}/${API_VERSION}/native)SERVO_OHOS_SIGNING_CONFIG: Path to json file containing a valid signing configuration for the demo app.
- Review the detailed instructions at Building for OpenHarmony.
- The target distribution can be modified by passing
--flavor=<default|harmonyos>to `mach <build|package|install>.
