The github.com/go-stack/stack package -documents the full list of formatting verbs and modifiers available. - -Custom Handlers - -The Handler interface is so simple that it's also trivial to write your own. Let's create an -example handler which tries to write to one handler, but if that fails it falls back to -writing to another handler and includes the error that it encountered when trying to write -to the primary. This might be useful when trying to log over a network socket, but if that -fails you want to log those records to a file on disk. - - type BackupHandler struct { - Primary Handler - Secondary Handler - } - - func (h *BackupHandler) Log (r *Record) error { - err := h.Primary.Log(r) - if err != nil { - r.Ctx = append(ctx, "primary_err", err) - return h.Secondary.Log(r) - } - return nil - } - -This pattern is so useful that a generic version that handles an arbitrary number of Handlers -is included as part of this library called FailoverHandler. - -Logging Expensive Operations - -Sometimes, you want to log values that are extremely expensive to compute, but you don't want to pay -the price of computing them if you haven't turned up your logging level to a high level of detail. - -This package provides a simple type to annotate a logging operation that you want to be evaluated -lazily, just when it is about to be logged, so that it would not be evaluated if an upstream Handler -filters it out. Just wrap any function which takes no arguments with the log.Lazy type. For example: - - func factorRSAKey() (factors []int) { - // return the factors of a very large number - } - - log.Debug("factors", log.Lazy{factorRSAKey}) - -If this message is not logged for any reason (like logging at the Error level), then -factorRSAKey is never evaluated. - -Dynamic context values - -The same log.Lazy mechanism can be used to attach context to a logger which you want to be -evaluated when the message is logged, but not when the logger is created. For example, let's imagine -a game where you have Player objects: - - type Player struct { - name string - alive bool - log.Logger - } - -You always want to log a player's name and whether they're alive or dead, so when you create the player -object, you might do: - - p := &Player{name: name, alive: true} - p.Logger = log.New("name", p.name, "alive", p.alive) - -Only now, even after a player has died, the logger will still report they are alive because the logging -context is evaluated when the logger was created. By using the Lazy wrapper, we can defer the evaluation -of whether the player is alive or not to each log message, so that the log records will reflect the player's -current state no matter when the log message is written: - - p := &Player{name: name, alive: true} - isAlive := func() bool { return p.alive } - player.Logger = log.New("name", p.name, "alive", log.Lazy{isAlive}) - -Terminal Format - -If log15 detects that stdout is a terminal, it will configure the default -handler for it (which is log.StdoutHandler) to use TerminalFormat. This format -logs records nicely for your terminal, including color-coded output based -on log level. - -Error Handling - -Becasuse log15 allows you to step around the type system, there are a few ways you can specify -invalid arguments to the logging functions. You could, for example, wrap something that is not -a zero-argument function with log.Lazy or pass a context key that is not a string. Since logging libraries -are typically the mechanism by which errors are reported, it would be onerous for the logging functions -to return errors. Instead, log15 handles errors by making these guarantees to you: - -- Any log record containing an error will still be printed with the error explained to you as part of the log record. - -- Any log record containing an error will include the context key LOG15_ERROR, enabling you to easily -(and if you like, automatically) detect if any of your logging calls are passing bad values. - -Understanding this, you might wonder why the Handler interface can return an error value in its Log method. Handlers -are encouraged to return errors only if they fail to write their log records out to an external source like if the -syslog daemon is not responding. This allows the construction of useful handlers which cope with those failures -like the FailoverHandler. - -Library Use - -log15 is intended to be useful for library authors as a way to provide configurable logging to -users of their library. Best practice for use in a library is to always disable all output for your logger -by default and to provide a public Logger instance that consumers of your library can configure. Like so: - - package yourlib - - import "github.com/inconshreveable/log15" - - var Log = log.New() - - func init() { - Log.SetHandler(log.DiscardHandler()) - } - -Users of your library may then enable it if they like: - - import "github.com/inconshreveable/log15" - import "example.com/yourlib" - - func main() { - handler := // custom handler setup - yourlib.Log.SetHandler(handler) - } - -Best practices attaching logger context - -The ability to attach context to a logger is a powerful one. Where should you do it and why? -I favor embedding a Logger directly into any persistent object in my application and adding -unique, tracing context keys to it. For instance, imagine I am writing a web browser: - - type Tab struct { - url string - render *RenderingContext - // ... - - Logger - } - - func NewTab(url string) *Tab { - return &Tab { - // ... - url: url, - - Logger: log.New("url", url), - } - } - -When a new tab is created, I assign a logger to it with the url of -the tab as context so it can easily be traced through the logs. -Now, whenever we perform any operation with the tab, we'll log with its -embedded logger and it will include the tab title automatically: - - tab.Debug("moved position", "idx", tab.idx) - -There's only one problem. What if the tab url changes? We could -use log.Lazy to make sure the current url is always written, but that -would mean that we couldn't trace a tab's full lifetime through our -logs after the user navigate to a new URL. - -Instead, think about what values to attach to your loggers the -same way you think about what to use as a key in a SQL database schema. -If it's possible to use a natural key that is unique for the lifetime of the -object, do so. But otherwise, log15's ext package has a handy RandId -function to let you generate what you might call "surrogate keys" -They're just random hex identifiers to use for tracing. Back to our -Tab example, we would prefer to set up our Logger like so: - - import logext "github.com/inconshreveable/log15/ext" - - t := &Tab { - // ... - url: url, - } - - t.Logger = log.New("id", logext.RandId(8), "url", log.Lazy{t.getUrl}) - return t - -Now we'll have a unique traceable identifier even across loading new urls, but -we'll still be able to see the tab's current url in the log messages. - -Must - -For all Handler functions which can return an error, there is a version of that -function which will return no error but panics on failure. They are all available -on the Must object. For example: - - log.Must.FileHandler("/path", log.JSONFormat) - log.Must.NetHandler("tcp", ":1234", log.JSONFormat) - -Inspiration and Credit - -All of the following excellent projects inspired the design of this library: - -code.google.com/p/log4go - -github.com/op/go-logging - -github.com/technoweenie/grohl - -github.com/Sirupsen/logrus - -github.com/kr/logfmt - -github.com/spacemonkeygo/spacelog - -golang's stdlib, notably io and net/http - -The Name - -https://xkcd.com/927/ - -*/ -package log diff --git a/log/format.go b/log/format.go index b7c6baa570b15..5cbbe3341ed00 100644 --- a/log/format.go +++ b/log/format.go @@ -2,18 +2,15 @@ package log import ( "bytes" - "encoding/json" "fmt" "math/big" "reflect" "strconv" - "strings" - "sync" - "sync/atomic" "time" "unicode/utf8" "github.com/holiman/uint256" + "golang.org/x/exp/slog" ) const ( @@ -24,61 +21,19 @@ const ( termCtxMaxPadding = 40 ) -// ResetGlobalState resets the fieldPadding, which is useful for producing -// predictable output. -func ResetGlobalState() { - fieldPaddingLock.Lock() - fieldPadding = make(map[string]int) - fieldPaddingLock.Unlock() -} - -// locationTrims are trimmed for display to avoid unwieldy log lines. -var locationTrims = []string{ - "github.com/XinFinOrg/XDPoSChain/", -} - -// PrintOrigins sets or unsets log location (file:line) printing for terminal -// format output. -func PrintOrigins(print bool) { - locationEnabled.Store(print) - if print { - stackEnabled.Store(true) - } -} - -// stackEnabled is an atomic flag controlling whether the log handler needs -// to store the callsite stack.
