This removes the config and code to output to statsd.
- Change `cmd.StatsAndLogging` to output a `Scope`, not a `Statter`.
- Remove the prefixing of component name (e.g. "VA") in front of stats; this was stripped by `autoProm` but now no longer needs to be.
- Delete vendored statsd client.
- Delete `MockStatter` (generated by gomock) and `mocks.Statter` (hand generated) in favor of mocking `metrics.Scope`, which is the interface we now use everywhere.
- Remove a few unused methods on `metrics.Scope`, and update its generated mock.
- Refactor `autoProm` and add `autoRegisterer`, which can be included in a `metrics.Scope`, avoiding global state. `autoProm` now registers everything with the `prometheus.Registerer` it is given.
- Change va_test.go's `setup()` to not return a stats object; instead the individual tests that care about stats override `va.stats` directly.
Fixes#2639, #2733.
StatsAndLogging is called early enough in each program that it precedes any gRPC
setup code that might need SetLogger already to have been set.
Fixes#2383
The `Version()` function is a less useful alternative to
`VersionString()` and isn't necessary. It used a fixed "0.1.0" prefix
that doesn't match a release tag, it also doesn't print Go & host
information that `VersionString()` does.
Less code = less bugs!
Implements a less RPC focused signal catch/shutdown method. Certain things that probably could also use this (i.e. `ocsp-updater`) haven't been given it as they would require rather substantial changes to allow for a graceful shutdown approach.
Fixes#2298.
This vendors the Prometheus client code, and exports metrics on the debug port, under `/metrics`.
This will currently export just the default metrics, like `go_goroutines`, `process_cpu_seconds_total`, `process_open_fds`, and `process_resident_memory_bytes`. Later work will start exporting Boulder-specific metrics, but this will allow Ops to start configuring scraping of Prometheus metrics in production.

Part of #2284
Updates #1699.
Adds a new package, `features`, which exposes methods to set and check if various internal features are enabled. The implementation uses global state to store the features so that services embedded in another service do not each require their own features map in order to check if something is enabled.
Requires a `boulder-tools` image update to include `golang.org/x/tools/cmd/stringer`.
Moves the wfe to it's own config file.
Each config will now belong in `test/config` and `test/config-next` analogous to `boulder-config` and `boulder-config-next`.
Under the new defaults, if the syslog section is missing, we'll use the default
config that we use in prod: no logs to stdout, INFO and below to syslog.
This allows us to remove the syslog section from prod configs, and potentially
move it to individual service configs in the future.
* Improve syslog defaults.
* Add stdout logging for purger test.
* Use plain int for sysloglevel.
* Fix JSON syntax
* Fix syslog config for expired-authz-purger.
https://github.com/letsencrypt/boulder/pull/1932
* 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.
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.
Consolidate initialization of stats and logging from each main.go into cmd
package.
Define a new config parameter, `StdoutLevel`, that determines the maximum log
level that will be printed to stdout. It can be set to 6 to inhibit debug
messages, or 0 to print only emergency messages, or -1 to print no messages at
all.
Remove the existing config parameter `Tag`. Instead, choose the tag from the
basename of the currently running process. Previously all Boulder log messages
had the tag "boulder", but now they will be differentiated by process, like
"boulder-wfe".
Shorten the date format used in stdout logging, and add the current binary's
basename.
Consolidate setup function in audit-logger_test.go.
Note: Most CLI binaries now get their stats and logging from the parameters of
Action. However, a few of our binaries don't use our custom AppShell, and
instead use codegangsta/cli directly. For those binaries, we export the new
StatsAndLogging method from cmd.

This allows us to call the Google Safe Browsing calls through the VA.
If the RA config's boolean UseIsSafeDomain is true, the RA will make the RPC
call to the VA during its NewAuthorization.
If the VA config's GoogleSafeBrowsingConfig struct is not nil, the VA
will check the Google Safe Browsing API in
VA.IsSafeDomain. If the GoogleSafeBrowsingConfig struct is nil, it will
always return true.
In order to actually make requests, the VA's GoogleSafeBrowsingConfig
will need to have a directory on disk it can store the local GSB hashes
it will check first and a working Google API key for the GSB API.
Fixes#1058
Adds a (currently gated) Akamai CCU API client used to purge GET OCSP responses
from the CDN. It also contains a small tool (cmd/akamai-purger) that can be used
to purge ARLs from the command line.
If a ServiceUnavailableError is returned from GenerateOCSP backoff before
attempting to retry the call as to not to overwhelm the CA with calls that
may instantly fail.
