Windows: Cargo should put files in ~/appdata, not directly in ~/

[briansmith]

In particular, everything should go in ~/appdata/locallow or ~/appdata/local,since ~/.cargo is just a cache, AFAICT.

This is FOLDERID_LocalAppData for SHGetKnownFolderPath, CSIDL_LOCAL_APPDATA for SHGetFolderPath, and %LOCALAPPDATA% in the environment.

cc #1734, a similar ish issue for linux

A practical reason for doing this is to avoid having automated backup/sync software backup/sync the .cargo directory.

[DanielKeep]

cargo-script already does this, using this code. Feel free to steal :)

Disclaimer on the function:

This is not chosen to match the location where Cargo places its cache data, because Cargo is wrong. This is at least less wrong.

As there hasn't been any activity here in a while would someone (the author, a team member, or any interested party) be able to summarise the current state, perhaps making explicit:

• Is this still relevant?
• If so, what is blocking it?
• Is it known what could be done to help move this forward?

Thank you!

(The cargo team is currently evaluating the use of Stale bot, and using #6035 as the tracking issue to gather feedback.)

If you're reading this comment from the distant future, fear not if this was closed automatically. If you believe it's still an issue please leave a comment and a team member can reopen this issue. Opening a new issue is also acceptable!

There has still been no movement on this front. The RFC is still open and the relevant teams still are unsure of themselves. Several implementations have popped up over time, and they've all been closed for various reasons.
