Variables

var ErrDurationMustBeString = errors.New("cannot JSON unmarshal something other than a string into a ConfigDuration")

ErrDurationMustBeString is returned when a non-string value is presented to be deserialized as a ConfigDuration

Functions

func CatchSignals

func CatchSignals(logger blog.Logger, callback func())

CatchSignals catches SIGTERM, SIGINT, SIGHUP and executes a callback method before exiting

func Clock

func Clock() clock.Clock

Clock functions similarly to clock.Default(), but the returned value can be changed using the FAKECLOCK environment variable if the 'integration' build flag is set.

This function returns the default Clock.

func FailOnError

func FailOnError(err error, msg string)

FailOnError exits and prints an error message if we encountered a problem

func FilterShutdownErrors

func FilterShutdownErrors(err error) error

FilterShutdownErrors returns the input error, with the exception of "use of closed network connection," on which it returns nil Per https://github.com/grpc/grpc-go/issues/1017, a gRPC server's `Serve()` will always return an error, even when GracefulStop() is called. We don't want to log graceful stops as errors, so we filter out the meaningless error we get in that situation.

func LoadCert

func LoadCert(path string) (cert []byte, err error)

LoadCert loads a PEM-formatted certificate from the provided path, returning it as a byte array, or an error if it couldn't be decoded.

func NewLogger

func NewLogger(logConf SyslogConfig) blog.Logger

func ReadConfigFile

func ReadConfigFile(filename string, out interface{}) error

ReadConfigFile takes a file path as an argument and attempts to unmarshal the content of the file into a struct containing a configuration of a boulder component.

func StatsAndLogging

func StatsAndLogging(logConf SyslogConfig, addr string) (metrics.Scope, blog.Logger)

StatsAndLogging constructs a metrics.Scope and an AuditLogger based on its config parameters, and return them both. It also spawns off an HTTP server on the provided port to report the stats and provide pprof profiling handlers. Crashes if any setup fails. Also sets the constructed AuditLogger as the default logger, and configures the cfssl, mysql, and grpc packages to use our logger. This must be called before any gRPC code is called, because gRPC's SetLogger doesn't use any locking.

func VersionString

func VersionString() string

VersionString produces a friendly Application version string.

Types

type CAADistributedResolverConfig

type CAADistributedResolverConfig struct {
	Timeout     ConfigDuration
	MaxFailures int
	Proxies     []string
}

CAADistributedResolverConfig specifies the HTTP client setup and interfaces needed to resolve CAA addresses over multiple paths

type ConfigDuration

type ConfigDuration struct {
	time.Duration
}

ConfigDuration is just an alias for time.Duration that allows serialization to YAML as well as JSON.

func (ConfigDuration) MarshalJSON

func (d ConfigDuration) MarshalJSON() ([]byte, error)

MarshalJSON returns the string form of the duration, as a byte array.

func (*ConfigDuration) UnmarshalJSON

func (d *ConfigDuration) UnmarshalJSON(b []byte) error

UnmarshalJSON parses a string into a ConfigDuration using time.ParseDuration. If the input does not unmarshal as a string, then UnmarshalJSON returns ErrDurationMustBeString.

func (*ConfigDuration) UnmarshalYAML

func (d *ConfigDuration) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML uses the same frmat as JSON, but is called by the YAML parser (vs. the JSON parser).

type DBConfig

type DBConfig struct {
	DBConnect string
	// A file containing a connect URL for the DB.
	DBConnectFile  string
	MaxDBConns     int
	MaxIdleDBConns int
}

DBConfig defines how to connect to a database. The connect string may be stored in a file separate from the config, because it can contain a password, which we want to keep out of configs.

func (*DBConfig) URL

func (d *DBConfig) URL() (string, error)

URL returns the DBConnect URL represented by this DBConfig object, either loading it from disk or returning a default value. Leading and trailing whitespace is stripped.

type GRPCClientConfig

type GRPCClientConfig struct {
	ServerAddresses []string
	Timeout         ConfigDuration
}

GRPCClientConfig contains the information needed to talk to the gRPC service

type GRPCServerConfig

type GRPCServerConfig struct {
	Address string `json:"address"`
	// ClientNames is a list of allowed client certificate subject alternate names
	// (SANs). The server will reject clients that do not present a certificate
	// with a SAN present on the `ClientNames` list.
	ClientNames []string `json:"clientNames"`
}

GRPCServerConfig contains the information needed to run a gRPC service

type GoogleSafeBrowsingConfig

type GoogleSafeBrowsingConfig struct {
	APIKey    string
	DataDir   string
	ServerURL string
}

GoogleSafeBrowsingConfig is the JSON config struct for the VA's use of the Google Safe Browsing API.

type HostnamePolicyConfig

type HostnamePolicyConfig struct {
	HostnamePolicyFile string
}

HostnamePolicyConfig specifies a file from which to load a policy regarding what hostnames to issue for.

type LogDescription

type LogDescription struct {
	URI string
	Key string
}

LogDescription contains the information needed to submit certificates to a CT log and verify returned receipts
