The standard library module
pwd
(password database access) doesn't exist on all systems (e.g. Windows or WASM), so don't rely on it. This just replaces the call to it with a default value if it is not there.This feature was only used in
ctapipe.core.metadata.Contact
to get the user's name if they forgot to explicitly include it, so it should not break things if it fails (which it currently does).
