When GnuPG refuses to encrypt a message (e.g. when key has expired), record
information about the failure and send to logs, then deliver cleartext. This
way we won't bounce email that could be delivered without encryption.
Also: add more E2E tests.
It's possible to trick Lacre by sending PGP markers in message body, causing
it to classify that message being already encrypted. This test case is used
to reproduce this scenario.
- Add a dedicated configuration file for lacre.daemon.
- Implement test/daemon_test.py like test/e2e_test.py, to automate the
following procedure:
1. Start up lacre.daemon.
2. For each test case, send test message to the daemon and verify that the
output received by test/utils/relay.py contains expected pattern.
- Simplify Makefile.
- Fix indentation here and there.
In particular, move:
- test utilities to test/utils;
- unit tests to test/modules.
Also: start implementing the Lacre daemon test (just a stub for now).
