I suspect we may change things more in the future as we blob's size just be the visible rect but this is an incremental step in the right direction. It also includes some changes to make sure that we always update our tiles appropriately.

wrench
wrench is a tool for debugging webrender outside of a browser engine.
headless
wrench has an optional headless mode for use in continuous integration. To run in headless mode, instead of using cargo run -- args, use ./headless.py args.
replay and show
Binary recordings can be generated by webrender and replayed with wrench replay. Enable binary recording in RendererOptions.
RendererOptions {
...
recorder: Some(Box::new(BinaryRecorder::new("wr-frame.bin"))),
...
}
If you are working on gecko integration you can enable recording in webrender_bindings/src/bindings.rs by setting
static ENABLE_RECORDING: bool = true;
wrench replay --save yaml will convert the recording into frames described in yaml. Frames can then be replayed with wrench show.
reftest
Wrench also has a reftest system for catching regressions.
- To run all reftests, run
script/headless.py reftest - To run specific reftests, run
script/headless.py reftest path/to/test/or/dir - To examine test failures, use the reftest analyzer
- To add a new reftest, create an example frame and a reference frame in
reftests/and then add an entry toreftests/reftest.list
