[turborepo] Prune is no longer copying package.json to full directory

[Xiot]

What version of Turborepo are you using?

1.10.10

What package manager are you using / does the bug impact?

Yarn v2/v3 (node_modules linker only)

What operating system are you using?

Mac

Describe the Bug

Running turbo prune --scope=X --docker properly pairs down the list of packages, however the root package.json doesn't seem to be copied into the full folder.

This causes yarn to think that there are 0 packages and it generates an empty lock file.

According to the docs, there should be a package.json in the full directory.

Expected Behavior

Copy the package.json into the full directory as well as the json directory

To Reproduce

turbo prune --scope=motion-dashboard --docker --out-dir ~/tmp/prune-test

root directory

json directory

full directory

With 1.10.9

root directory

json directory

full directory

No response

Thanks for the issue, #5769 should fix it.

Nice.

Currently I also need to copy over the .yarnrc file as well in order for the yarn install to work properly with the options that I have set up.

It looks like .npmrc is copied, but not the .yarnrc

I also just noticed that in either versions the .yarn/releases or .yarn/plugins were copied over either.

[chris-olszewski]

I'd be open to look into if we could copy over .yarnrc without making it a breaking change, but I'm pretty hesitant to start copying over more parts of .yarn.

I don't think that there's platform dependent code in .yarn/releases or .yarn/plugins, but if there is then just copying it as part of prune could lead to undesired behavior in the Docker container. I think having RUN yarn set version and RUN yarn plugin import in the Dockerfile would probably be less error-prone.

[Xiot]

That sounds good. And I'll look at explicitly calling set version and plugin import in my scripts.

I just need the .yarnrc for the linker config.

I'm fine copying the files over manually for my setup though.
Just wanted to raise it here since it was sort of related to my original issue.
