False positive warning on Windows due to upper/lower case drive letter: WARN Using manifest ... PIXI_PROJECT_MANIFEST rather than local ...

[Huite]

Checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pixi, using pixi --version.

Reproducible example

mkdir c:/tmp/case
cd c:/tmp/case
pixi init
pixi shell
pixi task list

Note the lower case on c:/.

Issue description

The example generates the following output:

C:\tmp via 🐍
❯ mkdir c:/tmp/case

C:\tmp via 🐍
❯ cd c:/tmp/case

c:\tmp\case
❯ pixi init
Created C:\tmp\case\pixi.toml

c:\tmp\case
❯ pixi shell
(case)
c:\tmp\case via 🅒 case
❯ pixi task list
 WARN Using manifest C:\tmp\case\pixi.toml from `PIXI_PROJECT_MANIFEST` rather than local c:\tmp\case\pixi.toml
No tasks found

I think it's due to pixi shell. This one doesn't trigger the warning:

cd c:/tmp/case
pixi init
pixi task list
cd C:/tmp/case
pixi task list
cd c:/tmp/case
pixi task list

Expected behavior

Ideally, on Windows, pixi doesn't care about upper or lower case for the drive letter.

Hey Huite 👋🏻

I am curious. How do you get a lower case drive letter in the first place?

But yes, this sounds like something we should fix.

Good morning Julian!

You get a lower case drive letter by explicitly cding as such: cd c:/tmp/case. As far as I can tell, this is just Windows being weird and inconsistent: if I do cd c:/TMP it normalizes the tmp part; but it never changes the drive letter (probably this has a bunch of reasons...).

You can see in my printed output that I initially start with an upper case letter, but after the change directory, it's showing a lower case:

C:\tmp via 🐍
❯ cd c:/tmp/case

c:\tmp\case

Windows preserves the case of the drive letter as you type it when changing directories.

Funnily enough, this isn't the first time I've had issues with this Windows "feature". A while ago, I had a different software application that failed completely because it could not find the directory -- I can't remember which, I should've made a note!
