Before using Niv, we were following channels meaning we can not
reproduce CI jobs easily.
In this change, we use Niv to pin these dependencies. We are also
addding a tests/default.nix to be able to run these tests locally.
For instance, to run the test extern.nix on the nixpkgs-19.09 release:
nix-build tests/default.nix -A extern.nixpkgs_19_09
Fixes#178
The current version fetches clamav-db-files from gitlab,
in the master branch. This is currently broken as the files
were removed, and does not allow to ensure a fixture update
does not break the test
- restructure rspamd config. It's nicer now, and it was getting
overridden the old way.
- "scan_mime_parts = false" apparently must be used in rspamd for ClamAV
to work
- refactor the clamav test a bit for cleanliness
- wait for rspamd and clamd sockets to open, before testing
- use clamdscan for speed, and verify that the virus was found
- verify msmtp returns virus scan result
Fix#136 (stop pulling the files from @griff's poor server), also add a script
to update the files.
The fun thing about this is that due to sourcing the files from
`https://gitlab.com/simple-nixos-mailserver/nixos-mailserver/raw/master/tests/clamav`
during the tests, updates to the `hashes.json` and `*.cvd` files will always
fail CI. I guess this is a reasonable tradeoff as long as people are aware of
it.
