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
Their CI environment currently doesn't have KVM. This commit should be
reverted when/if they do, for much better CI speed.
You can still run tests locally on your KVM-enabled machine as documented
on the wiki.
Workaround on GitLab is several pieces (injected through .gitlab-ci.yml):
- Make a /dev/kvm file so that nix thinks we have "kvm" system feature
and proceeds with executing the tests.
- Inject a QEMU package that replaces qemu-kvm with a full emulator.
- Monkey-patch the test script to wait longer for the VM to boot, since
it's slow on full emulation. 1200 seconds, double the previous value.
The patch method is not bulletproof, but better than maintaining forks of
nixpkgs.
- Set systemd's DefaultTimeoutStartSec=15min, so nix's "backdoor" test
service doesn't time out on the slow boot.
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.
The extern test used shell scripting for file writing and ip lookup
which Nix and make-test.nix can do. I have also replaced the 5 second
sleep with the check for completion of queue processing on server.
