Status in duplicity - Bandwidth Efficient Encrypted Backup: Fix Released
Bug description:
When running 'list-current-files' using '--archive-dir' when the archive dir
doesn't exist, the commands fails with an encryption error.
Steps to reproduce;
$ mkdir source
$ touch source/test
$ duplicity source backup
$ mkdir cache
$ duplicity list-current-files --archive-dir ./cache backup
===== Begin GnuPG log =====
gpg: CAST5 encrypted data
gpg: encrypted with 1 passphrase
gpg: decryption failed: bad key
===== End GnuPG log ====
This is because there is an 'early out' in the password handling that checks to
see if we are running 'list-current-files' with a local archive, in which case
it doesn't ask for the password. This is wrong in this case because even though
the archive exists, it doesn't have any signature files.
The attached patch moves the password querying to separate module which only
asks the user for the password when it is required. As the signature file class
correctly falls back to the backend when the files aren't available in the
cache, this fixes the bug (as well as removes a bunch of special case checks
for when the password needs to be read).
