* Fix all errcheck errors
* Add errcheck to test.sh
* Add a new sa.Rollback method to make handling errors in rollbacks easier.
This also causes a behavior change in the VA. If a HTTP connection is
abruptly closed after serving the headers for a non-200 response, the
reported error will be the read failure instead of the non-200.
- Remove error signatures from log methods. This means fewer places where errcheck will show ignored errors.
- Pull in latest cfssl to be compatible with errorless log messages.
- Reduce the number of message priorities we support to just those we actually use.
- AuditNotice -> AuditInfo
- Remove InfoObject (only one use, switched to Info)
- Remove EmergencyExit and related functions in favor of panic
- Remove SyslogWriter / AuditLogger separate types in favor of a single interface, Logger, that has all the logging methods on it.
- Merge mock log into logger. This allows us to unexport the internals but still override them in the mock.
- Shorten names to be compatible with Go style: New, Set, Get, Logger, NewMock, etc.
- Use a shorter log format for stdout logs.
- Remove "... Starting" log messages. We have better information in the "Versions" message logged at startup.
Motivation: The AuditLogger / SyslogWriter distinction was confusing and exposed internals only necessary for tests. Some components accepted one type and some accepted the other. This made it hard to consistently use mock loggers in tests. Also, the unnecessarily fat interface for AuditLogger made it hard to meaningfully mock out.
Fixes https://github.com/letsencrypt/boulder/issues/1212.
This exposes a new constructor in amqp-rpc.go specifically for ActivityMonitor,
which overrides the normal routingKey to be the wildcard "#".
It also adds an expvar for the number of messages processed in ActivityMonitor,
and adds an integration test case that checks that ActivityMonitor has received
more than zero messages.
In the process, break out AMQP config into its own struct, one per service.
The AMQPConfig struct is included by composition in the config structs that need
it. If any given service lacks an AMQP config of its own, it gets a default
value from the top-level AMQP config struct, for deployability reasons.
Tightens the RPC code to take a specific AMQP config, not an over-broad
cmd.Config.
Shortens construction of specific RPC clients so they instatiate the generic
client connection themselves, simplifying per-service startup code.
Remove unused SetTimeout method on RPC clients.
