If an external image shows up multiple times while using a different image rendering setting on each instance, we can erroneously call handler.lock() for each instance in parallel, thus defaulting to the last image rendering setting supplied for all instances in that batch. To work around this, we get rid of the concept of having RenderTextureHosts maintain and set the image rendering state, which results in a nice simplification. Then, when we go to actually bind an external image inside WebRender, we set the image rendering state at that point, so that regardless of how many instances of an external image are locked simultaneously, we always use the correct image rendering setting for a batch.

wrench
wrench is a tool for debugging webrender outside of a browser engine.
Build
Build wrench with cargo build --release within the wrench directory.
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.
show
If you are working on gecko integration you can capture a frame via the following steps.
- Visit about:support and check that the "Compositing" value in the "Graphics" table says "WebRender". Enable
gfx.webrender.allin about:config if necessary to enable WebRender. - Hit ctrl-shift-3 to capture the frame. The data will be put in
~/wr-capture. - View the capture with
wrench show ~/wr-capture.
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
