Functions ¶

func AppendWithTime ¶

func AppendWithTime(ts time.Time, level, source, message string)

AppendWithTime records an externally supplied message while preserving the caller's timestamp. Used when replaying frontend logs whose clock may lead or lag the server. Used when replaying frontend logs whose clock may lead/lag the server.

func ClearBuffer ¶

func ClearBuffer()

ClearBuffer drops every buffered backend + frontend entry.

func Debug ¶

func Debug(format string, args ...any)

func Debugf ¶

func Debugf(ctx context.Context, format string, args ...any)

func Error ¶

func Error(format string, args ...any)

func Errorf ¶

func Errorf(ctx context.Context, format string, args ...any)

func Fatalf ¶

func Fatalf(ctx context.Context, format string, args ...any)

func GetLevel ¶

func GetLevel() string

GetLevel returns the current level as a lowercase string.

func Info ¶

func Info(format string, args ...any)

func Infof ¶

func Infof(ctx context.Context, format string, args ...any)

func SetLevel ¶

func SetLevel(name string) bool

SetLevel changes the global log level at runtime. Accepts the strings "debug", "info", "warn", "error" (case-insensitive). Unknown values leave the level unchanged and return false.

func Warn ¶

func Warn(format string, args ...any)

func Warnf ¶

func Warnf(ctx context.Context, format string, args ...any)

Types ¶

type Entry ¶

type Entry struct {
	ID        uint64    `json:"id"`
	Timestamp time.Time `json:"timestamp"`
	Level     string    `json:"level"`
	Source    string    `json:"source"`
	Message   string    `json:"message"`
}

Entry is a single log record captured by the in-memory ring buffer. It is exposed through the /api/v1/logs endpoint so the settings UI can show recent backend logs without having to tail stdout.

func RecentEntries ¶

func RecentEntries(f Filter) []Entry

RecentEntries is the package-level accessor used by HTTP handlers.

type Filter ¶

type Filter struct {
	MinLevel string
	Kind     string
	Sources  []string
	Since    uint64
	Limit    int
	Keyword  string
}

Filter narrows a RecentEntries query. A zero-value Filter returns everything the buffer still holds (newest first).

Kind partitions entries into the high-level "backend" / "frontend" buckets the settings UI exposes. Frontend entries are tagged with a "frontend" source prefix by the /api/v1/logs/frontend handler; everything else is treated as backend. Use Sources for exact-match component filtering.
