Constants ¶
const ( // LogTimestampFormat defines the timestamp format in log files LogTimestampFormat = "2006-01-02T15:04:05.000" // LogTimestampFormatUTC defines the utc timestamp format in log files LogTimestampFormatUTC = "2006-01-02T15:04:05.000Z" )
Variables ¶
var SkipReplacingGlobalLoggers bool
SkipReplacingGlobalLoggers will cause `Configure()` to skip replacing global loggers. This is mostly a hack: command line applications are expected to call `log.Configure()` in their subcommand actions, and that should indeed always replace global loggers, as well. But when running tests, we invoke the subcommand actions multiple times, which is thus re-configuring the logger repeatedly. Because global logger are per definition a global shared resource, the consequence is that we might end up replacing the global loggers while tests are using them, and this race rightfully gets detected by Go's race detector.
This variable should thus only be set in the testhelper's setup routines such that we configure the global logger a single time for all of our tests, only.
Functions ¶
func ConvertLoggingFields ¶
func ConvertLoggingFields(fields grpcmwloggingv2.Fields) map[string]any
ConvertLoggingFields converts Fields in go-grpc-middleware/v2/interceptors/logging package into a general map[string]interface{}. So that other logging packages (such as Logrus) can use them.
func InitContextCustomFields ¶
InitContextCustomFields returns a new context with `CustomFields` added to the given context.
func NewSyncWriter ¶
NewSyncWriter returns Writer wrapped with a mutex that is acquired before each Write call.
func UTCJsonFormatter ¶
UTCJsonFormatter returns a Formatter that formats a logrus Entry's as json and converts the time field into UTC
func UTCTextFormatter ¶
UTCTextFormatter returns a Formatter that formats a logrus Entry's as text and converts the time field into UTC
Types ¶
type Config ¶
type Config struct {
Format string `json:"format" toml:"format,omitempty"`
Level string `json:"level" toml:"level,omitempty"`
}
Config contains logging configuration values
type CustomFields ¶
CustomFields stores custom fields, which will be logged as a part of gRPC logs. The gRPC server is expected to add corresponding interceptors. They initialize a CustomFields object and inject it into the context. Callers can pull the object out with CustomFieldsFromContext.
func CustomFieldsFromContext ¶
func CustomFieldsFromContext(ctx context.Context) *CustomFields
CustomFieldsFromContext gets the `CustomFields` from the given context.
func (*CustomFields) Fields ¶
func (fields *CustomFields) Fields() Fields
Fields returns all the fields as Fields
func (*CustomFields) RecordMax ¶
func (fields *CustomFields) RecordMax(key string, value int)
RecordMax will store the max value for a given key.
func (*CustomFields) RecordMetadata ¶
func (fields *CustomFields) RecordMetadata(key string, value any)
RecordMetadata records a string metadata for the given key.
func (*CustomFields) RecordSum ¶
func (fields *CustomFields) RecordSum(key string, value int)
RecordSum sums up all the values for a given key.
type Logger ¶
type Logger interface {
WithField(key string, value any) Logger
WithFields(fields Fields) Logger
WithError(err error) Logger
Debug(msg string)
Info(msg string)
Warn(msg string)
Error(msg string)
DebugContext(ctx context.Context, msg string)
InfoContext(ctx context.Context, msg string)
WarnContext(ctx context.Context, msg string)
ErrorContext(ctx context.Context, msg string)
StreamServerInterceptor(...grpcmwlogrus.Option) grpc.StreamServerInterceptor
UnaryServerInterceptor(...grpcmwlogrus.Option) grpc.UnaryServerInterceptor
// Output returns the loggers output where fully formatted log entries can be written.
Output() io.Writer
}
Logger is the logging type used by Gitaly.
func Configure ¶
Configure configures the default and gRPC loggers. The gRPC logger's log level will be mapped in order to decrease its default verbosity. Returns the configured default logger that would also be returned by `Default()`.
func ConfigureCommand ¶
func ConfigureCommand() Logger
ConfigureCommand configures the logging infrastructure such that it can be used with simple one-off commands. This configuration is supposed to be opinionated and ensures that all one-off commands behave in a sane way:
The server configuration does not influence logs generated by the command. This is done intentionally as you don't want to force administrators to adapt the server configuration to influence normal commands.
The output always goes to stderr such that output that is supposed to be consumed can be separated from log messages.
The output uses text format as it is supposed to be human-readable, not machine-readable.
The default log level is set to "error" such that we don't generate tons of log messages that are ultimately uninteresting.
Servers and commands with special requirements should instead use `Configure()`.
type LogrusLogger ¶
type LogrusLogger struct {
// contains filtered or unexported fields
}
LogrusLogger is an implementation of the Logger interface that is implemented via a `logrus.FieldLogger`.
func FromContext ¶
func FromContext(ctx context.Context) LogrusLogger
FromContext extracts the logger from the context. If no logger has been injected then this will return a discarding logger.
func FromLogrusEntry ¶
func FromLogrusEntry(entry *logrus.Entry) LogrusLogger
FromLogrusEntry constructs a new Gitaly-specific logger from a `logrus.Logger`.
func (LogrusLogger) Data ¶
func (l LogrusLogger) Data() Fields
Data returns the data stored inside the logger entry.
func (LogrusLogger) Debug ¶
func (l LogrusLogger) Debug(msg string)
Debug writes a log message at debug level.
func (LogrusLogger) DebugContext ¶
func (l LogrusLogger) DebugContext(ctx context.Context, msg string)
DebugContext logs a new log message at Debug level. Fields added to the context via AddFields will be appended.
func (LogrusLogger) Error ¶
func (l LogrusLogger) Error(msg string)
Error writes a log message at error level.
func (LogrusLogger) ErrorContext ¶
func (l LogrusLogger) ErrorContext(ctx context.Context, msg string)
ErrorContext level. Fields added to the context via AddFields will be appended.

func (l LogrusLogger) Info(msg string)
Info writes a log message at info level.
func (LogrusLogger) InfoContext ¶
func (l LogrusLogger) InfoContext(ctx context.Context, msg string)
InfoContext logs a new log message at Info level. Fields added to the context via AddFields will be appended.
func (LogrusLogger) LogrusEntry
deprecated
func (l LogrusLogger) LogrusEntry() *logrus.Entry
LogrusEntry returns the `logrus.Entry` that backs this logger. Note that this interface only exists during the transition period and will be eventually removed. It is thus heavily discouraged to use it.
Deprecated: This will be removed once all callsites have been converted to do something that is independent of the logrus logger.

func (l LogrusLogger) Output() io.Writer
Output returns the loggers output where fully formatted log entries can be written.
