"path too long" error on Windows from cargo prisma "generate"

[ilkka]

Describe the bug

Running pnpm prep for 6c7b224 causes the following on my Windows 11 machine:

> spacedrive@0.0.0 prep C:\Users\ilkka.poutanen\Code\spacedrive
> pnpm db:gen


> spacedrive@0.0.0 db:gen C:\Users\ilkka.poutanen\Code\spacedrive
> pnpm core prisma generate


> spacedrive@0.0.0 core C:\Users\ilkka.poutanen\Code\spacedrive
> pnpm --filter @sd/core --  "prisma" "generate"


> @sd/core@0.0.0 prisma C:\Users\ilkka.poutanen\Code\spacedrive\core
> cargo prisma "generate"

I'm not super well versed on Windows particulars, but based on some Googling I believe this might be caused by something down in there using old APIs that don't allow paths longer than 260 characters. I do have the registry key for long path support turned on.

Anyway, I do understand that letting Windows users build the app at this point is probably quite low down on your list of priorities, just though I'd report this to give you a heads up on possible future problems wrt making Windows binaries :)

Cheers!

This is strange considering that others have had success with building Spacedrive on Windows. I notice you're using 1.62.0-nightly rather than 1.60.0 stable, is there a particular reason you are doing so? The recommended Rust version for Spacedrive is 1.60.0. I doubt that is causing the path length issue though.

@oscartbeaumont Any ideas?

[ilkka]

Ah, no other reason for the nightly than pnpm prep earlier complaining about needing something from the nightly toolchain, but I guess my stuff was just plain too old :)

FWIW got the same thing on 1.60.0, but since:

• the offending pathname is just over the limit at 265 chars
• I've got a long username due to corporate policy :D
• both scoop and rustup make the path longer

...I can easily believe that I'd just be the first unlucky sod to hit this limit.

[Brendonovich]

From what I can tell, long file paths are an outstanding issue in Cargo and there's not really anything we can do about it 😅

Progress is being tracked here: rust-lang/cargo#9770

Will close this for now due to the previous comment about it being an issue within Cargo — nothing we will be able to do until this gets fixed upstream :( #118 (comment)
