Describe the bug

Originally, @asvetlov intended to delete any use of attrs from aiohttp 4.0+ series via aio-libs/aiohttp#5284. He dropped it from the runtime deps too.

But there are some places that still rely on attrs meaning that this will cause failures in runtime because of the missing dep. The tests currently succeed because attrs is listed as a test dep.

right now we only mark the local branches that are tied to a remote tracking branch:

would be nice to have a similar marker for the corresponding remote branches:

Is it possible for sqlx to have an impl of Decode for Cow<'_, str> (with implementation delegation to str, similar to what String is doing)?

Stitching API

Opencv provide a Stitching module/API

Bascially, i would like to be able to rewrite stitching_detailed.cpp in javascript

This includes :

• Stitcher class
• Features extractors (already implemented in opencv4nodejs)
• Estimator

What should happen if deliver_cancel raises an exception? In the current implementation, the shielded cancel scope will prevent it from propagating until the process exits, which might take a while if the crash occurred before signaling the process in any way. Maybe on exception from a user-specified deliver_cancel we should call the default deliver_cancel to kill the process? Or just kill() since
