attic check with ATTIC_PASSPHRASE -- getpass.py/terminal issue #374
Description
I run attic check from cron (daily while testing, once a week in future). Attic uses a $ATTIC_PASSPHRASE set in the environment. This is running from cron.
attic check does the repository check OK but when it does the archive consistency check it fails with:
Starting repository check...
Repository check complete, no problems found.
Starting archive consistency check...
/usr/lib/python3.4/getpass.py:92: GetPassWarning: Can not control echo on the terminal.
passwd = fallback_getpass(prompt, stream)
Warning: Password input may be echoed.

Is this a known issue and is there a command line parameter or environment variable or similar that I can set to make getpass.py not break when it thinks it's not talking to a terminal?
I think I could possibly get this working if I set up ssh key auth and have the cron job ssh to localhost to run attic-check. I'll test that (haven't yet) if there is no more standard way to fix.
