There is a new protobuf library (and corresponding code generator) for
Go: google.golang.org/protobuf.
It is fairly compatible with the previous v1 API
(github.com/golang/protobuf), but there are some changes.
This patch adjusts the code and generated files to the new API.
The on-wire/on-disk format remains unchanged so this should be
transparent to the users.
This patch updates the auto-generated code to match the latest tooling
versions.
In particular, the protobufs are regenerated, and the new version no
longer supports unkeyed literals, so some minor changes are needed.
Other than that, the cipher list is extended with the latest ciphers.
This patch makes chasquid reload domaininfo periodically, so it notices
any external changes made to it.
It is in line with what we do for aliases and authentication already,
and makes it possible for external removals an additions to the
domaininfo database to be picked up without a restart.
This patch adds a missing docstrings for exported identifiers, and
adjust some of the existing ones to match the standard style.
In some cases, the identifiers were un-exported after noticing they had
no external users.
Besides improving documentation, it also reduces the linter noise
significantly.
We have many places in our tests where we create temporary directories,
which we later remove (most of the time). We have at least 3 helpers to
do this, and various places where it's done ad-hoc (and the cleanup is
not always present).
To try to reduce the clutter, and make the tests more uniform and
readable, this patch introduces two helpers in a new "testutil" package:
one for creating and one for removing temporary directories.
These new functions are safer, better tested, and make the tests more
consistent. All the tests are updated to use them.
This patch introduces a new "domaininfo" package, which implements a
database with information about domains. In particular, it tracks
incoming and outgoing security levels.
That information is used in incoming and outgoing SMTP to prevent
downgrades.
