fix(embedded): Don't pollute script dir with lockfile #12284
Conversation
This puts the lockfile back into a target directory in the users home, like before rust-lang#12268. Another idea that came up was to move the workspace root to be in the target directory (which would effectively be like pre-rust-lang#12268) but I think that is a bit hacky / misleading. This does mean that the lockfile is buried away from the user and they can't pass it along with their script. In most cases I've dealt with, this would be fine. When the lockfile is needed, they will also most likely have a workspace, so it shoud have a local lockfile in that case. The inbetween case is something that needs further evaluation for whether we should handle it and how.

Looks good.
Just this line ws.root()
needs to be replaced with lock_root
.

Thanks for catching that! I've pushed a fix |

What does this PR try to resolve?
This puts the lockfile back into a target directory in the users home,
like before #12268.
Another idea that came up was to move the workspace root to be in the
target directory (which would effectively be like pre-#12268) but I
think that is a bit hacky / misleading.
This does mean that the lockfile is buried away from the user and they
can't pass it along with their script. In most cases I've dealt with,
this would be fine. When the lockfile is needed, they will also most
likely have a workspace, so it shoud have a local lockfile in that case.
The inbetween case is something that needs further evaluation for
whether we should handle it and how.
How should we test and review this PR?
Its a bit difficult to test for the lockfile in the new location, so this is mostly being tested in that the lockfile no longer exists next to the script.
