uninstalled package still in the index? about spack HOT 4 CLOSED

spack uninstall does not delete things from the database if they are referenced by some dependent.

spack reindex does not delete existing entries from the database

You can ignore those warnings

from spack.

I see.
Thanks for the explaination.
I will close the issue then.

If i uninstall stuff with spack gc it means that it's stuff that is not referenced by anything, right?
If so, why is it not removed from the database?

Also, if i spack spec something that has been removed but for which spack reindex gives a warning, it appears with [-] coloured in red rather than the standard colour.
What does that mean?

I'm just trying to understand the uninstall/reindex process and behaviour

from spack.

spack gc deletes install prefixes from the file system, and usually doesn't delete anything from the database. We keep track of what build deps were (originally) used, so you could reinstall them later.

So [-] means it is no longer installed on the file system.
