Replaces https://github.com/astral-sh/uv/pull/12320 Switches to Depot for the large Windows runner we use for `cargo test`. The runtime goes from 8m 20s -> 6m 44s (total) and 7m 18s -> 4m 41s (test run) which are 20% and 35% speedups respectively. A few things got marginally slower, like Python installs went from 11s -> 38s, the Rust cache went from 15s -> 30s, and drive setup went from 7s -> 20s.

# Configures a drive for testing in CI.
|
|
#
|
|
# When using standard GitHub Actions runners, a `D:` drive is present and has
|
|
# similar or better performance characteristics than a ReFS dev drive. Sometimes
|
|
# using a larger runner is still more performant (e.g., when running the test
|
|
# suite) and we need to create a dev drive. This script automatically configures
|
|
# the appropriate drive.
|
|
#
|
|
# When using GitHub Actions' "larger runners", the `D:` drive is not present and
|
|
# we create a DevDrive mount on `C:`. This is purported to be more performant
|
|
# than an ReFS drive, though we did not see a change when we switched over.
|
|
#
|
|
# When using Depot runners, the underling infrastructure is EC2, which does not
|
|
# support Hyper-V. The `New-VHD` commandlet only works with Hyper-V, but we can
|
|
# create a ReFS drive using `diskpart` and `format` directory. We cannot use a
|
|
# DevDrive, as that also requires Hyper-V. The Depot runners use `D:` already,
|
|
# so we must check if it's a Depot runner first, and we use `V:` as the target
|
|
# instead.
