fix: rename rustfmt test modules to avoid case-insensitive path collisions by cataggar · Pull Request #154639 · rust-lang/rust

cataggar · 2026-03-31T13:54:03Z

Summary

Cloning the rust repo on case-insensitive filesystems (e.g. Windows, macOS) produces a git warning about colliding paths:

warning: the following paths have collided (e.g. case-sensitive paths
on a case-insensitive filesystem) and only one from the same
colliding group is in the working tree:

  'src/tools/rustfmt/tests/source/reorder_modules/ABCD/mod.rs'
  'src/tools/rustfmt/tests/source/reorder_modules/abcd/mod.rs'
  'src/tools/rustfmt/tests/source/reorder_modules/ZYXW/mod.rs'
  'src/tools/rustfmt/tests/source/reorder_modules/zyxw/mod.rs'
  'src/tools/rustfmt/tests/target/reorder_modules/ABCD/mod.rs'
  'src/tools/rustfmt/tests/target/reorder_modules/abcd/mod.rs'
  'src/tools/rustfmt/tests/target/reorder_modules/ZYXW/mod.rs'
  'src/tools/rustfmt/tests/target/reorder_modules/zyxw/mod.rs'

Why they were named this way

These were added by @calebcartwright in 2d049af8f0e (rust-lang/rustfmt#6368) and brought into this repo via the rustfmt subtree update (#153145). The ABCD/abcd and ZYXW/zyxw directories test case-sensitive module sorting — Edition ≤ 2021 uses str::cmp (ASCII order) while Edition ≥ 2024 uses version_sort. The collision on case-insensitive filesystems was not considered since development was on Linux.

Fix

Rename the lowercase directory variants to avoid the collision:

abcd → abcde
zyxw → zyxwv

All mod abcd; / mod zyxw; declarations in the 10 affected test files are updated accordingly. This preserves the test intent (verifying case-sensitive module sorting across style editions) while eliminating the warning on case-insensitive filesystems.

…sions Cloning the repo on Windows leads to this warning: warning: the following paths have collided (e.g. case-sensitive paths on a case-insensitive filesystem) and only one from the same colliding group is in the working tree: 'src/tools/rustfmt/tests/source/reorder_modules/ABCD/mod.rs' 'src/tools/rustfmt/tests/source/reorder_modules/abcd/mod.rs' 'src/tools/rustfmt/tests/source/reorder_modules/ZYXW/mod.rs' 'src/tools/rustfmt/tests/source/reorder_modules/zyxw/mod.rs' 'src/tools/rustfmt/tests/target/reorder_modules/ABCD/mod.rs' 'src/tools/rustfmt/tests/target/reorder_modules/abcd/mod.rs' 'src/tools/rustfmt/tests/target/reorder_modules/ZYXW/mod.rs' 'src/tools/rustfmt/tests/target/reorder_modules/zyxw/mod.rs' Rename the lowercase variants (abcd -> abcde, zyxw -> zyxwv) to avoid case-insensitive collisions while preserving test intent.

@cataggar these are great, thanks! I'd be happy to move forward with the change as is, but what I'm wondering is how we can prevent this from happening in the future? Maybe we could write a unit test to ensure that all files in test/{source|target}/* are unique?
