The docopt-go library is quite convenient, but it has been abandoned for
a while :(
Since we only use it for chasquid-util, this patch removes it and
replaces it with a custom small parser, that is a reasonable fit for the
required use cases.
The patch also adds a couple of tests to increase coverage.
NOTE: docopt-go accepted some undocumented behaviour, in particular the
use of "-a b" instead of "-a=b". The new parser does not, so some
user scripts may require updating.
I think this should be rare enough not to be worth the complexity of
adjusting the parser to allow it.
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 adds a chasquid-util subcommand to remove a domain
information entry.
The main use case is to manually allow a security level downgrade, after
performing manual verification.
This patch changes chasquid-util's subcommands and parameters to
(hopefully) make them more user friendly and intuitive by default.
The changes include defaulting the configuration to /etc/chasquid, and
using full addresses as usernames.
It also adds some shell tests to cover most of the functionality.
