First check

• I added a very descriptive title to this issue.
• I used the GitHub search to find a similar issue and didn't find it.
• I searched the FastAPI documentation, with the integrated search.
• I already searched in Google "How to X in FastAPI" and didn't find any information.
• I already read and followed all the tutorial in the docs and didn't find an answ

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.

Describe the bug
Since 0.16.0 and onwards, quitting GitUI seems to be significantly slower than it used to on Windows. This does not appear to be the case on my Linux machines, however.

To Reproduce
Steps to reproduce the behavior:

1. Install gitui @ 0.16.2
2. Run a terminal like cmd.exe (also tested in pwsh.exe)
3. Navigate to a repository
4. Open gitui in a repository
5. Quit g

Not a big deal since I usually have DATABASE_URL in .env anyways, but I just noticed in a new project before creating .env that sqlx mig add init failed with

error: The DATABASE_URL environment variable must be set

Which there doesn't seem to be a good reason for.

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
