Functions ¶
func Copy ¶ added in v0.10.0
Copy extracts the tracing Span and logging entry from the src Context, if they exist, and adds them to the dst Context.
This is useful to share tracing and logging between contexts, but not the cancellation. For example, if the src Context has been cancelled but cleanup operations triggered by the cancellation require a non-cancelled context to execute.
func DurationFormatMilliseconds ¶ added in v0.10.0
func DurationFormatSeconds ¶ added in v0.10.0
func DurationFormatString ¶ added in v0.10.0
func Format ¶ added in v0.10.0
Format formats an object into a JSON string, without any indendtation or HTML escapes. Context is used to output a log waring if the conversion fails.
This is intended primarily for `trace.StringAttribute()`
func FormatIO ¶ added in v0.10.0
FormatIO formats net.Conn and other types that have an `Addr()` or `Name()`.
See FormatEnabled for more information.
func FormatTime ¶ added in v0.10.0
func GetEntry ¶ added in v0.10.0
GetEntry returns a `logrus.Entry` stored in the context, if one exists. Otherwise, it returns a default entry that points to the current context.
Note: if the a new entry is returned, it will reference the passed in context. However, existing contexts may be stored in parent contexts and additionally reference earlier contexts. Use `UpdateContext` to update the entry and context.
func IsScrubbingEnabled ¶ added in v0.10.0
func IsScrubbingEnabled() bool
IsScrubbingEnabled checks if scrubbing is enabled
func ScrubBridgeCreate ¶ added in v0.10.0
ScrubBridgeCreate scrubs requests sent over the bridge of type internal/gcs/protocol.containerCreate wrapping an internal/hcsoci.linuxHostedSystem
func ScrubBridgeExecProcess ¶ added in v0.10.0
ScrubBridgeExecProcess scrubs requests sent over the bridge of type internal/gcs/protocol.containerExecuteProcess
func ScrubProcessParameters ¶ added in v0.10.0
ScrubProcessParameters scrubs HCS Create Process requests with config parameters of type internal/hcs/schema2.ScrubProcessParameters (aka hcsshema.ScrubProcessParameters)
func SetEntry ¶ added in v0.10.0
SetEntry updates the log entry in the context with the provided fields, and returns both. It is equivalent to:
entry := GetEntry(ctx).WithFields(fields) ctx = WithContext(ctx, entry)
See WithContext for more information.
func UpdateContext ¶ added in v0.10.0
UpdateContext extracts the log entry from the context, and, if the entry's context points to a parent's of the current context, ands the entry to the most recent context. It is equivalent to:
entry := GetEntry(ctx) ctx = WithContext(ctx, entry)
This allows the entry to reference the most recent context and any new values (such as span contexts) added to it.
See WithContext for more information.
func WithContext ¶ added in v0.10.0
WithContext returns a context that contains the provided log entry. The entry can be extracted with `GetEntry` (`G`)
The entry in the context is a copy of `entry` (generated by `entry.WithContext`)
Types ¶
type DurationFormat ¶ added in v0.10.0
DurationFormat formats a time.Duration log entry.
A nil value signals an error with the formatting.
type Hook ¶ added in v0.10.0
type Hook struct {
// EncodeAsJSON formats structs, maps, arrays, slices, and [bytes.Buffer] as JSON.
// Variables of [bytes.Buffer] will be converted to []byte.
//
// Default is false.
EncodeAsJSON bool
// FormatTime specifies the format for [time.Time] variables.
// An empty string disables formatting.
// When disabled, the fall back will the JSON encoding, if enabled.
//
// Default is [github.com/containerd/containerd/log.RFC3339NanoFixed].
TimeFormat string
// Duration format converts a [time.Duration] fields to an appropriate encoding.
// nil disables formatting.
// When disabled, the fall back will the JSON encoding, if enabled.
//
// Default is [DurationFormatString], which appends a duration unit after the value.
DurationFormat DurationFormat
// AddSpanContext adds [logfields.TraceID] and [logfields.SpanID] fields to
// the entry from the span context stored in [logrus.Entry.Context], if it exists.
AddSpanContext bool
}
Hook intercepts and formats a logrus.Entry before it logged.
The shim either outputs the logs through an ETW hook, discarding the (formatted) output or logs output to a pipe for logging binaries to consume. The Linux GCS outputs logrus entries over stdout, which is then consumed and re-output by the shim.
