This can be configured via: - -- `-account.json` is a path to the Ethereum account's JSON key file -- `-account.pass` is a path to a text file with the decryption passphrase - -The faucet is able to distribute various amounts of Ether in exchange for various timeouts. These can be configured via: - -- `-faucet.amount` is the number of Ethers to send by default -- `-faucet.minutes` is the time to wait before allowing a rerequest -- `-faucet.tiers` is the funding tiers to support (x3 time, x2.5 funds) - -## Sybil protection - -To prevent the same user from exhausting funds in a loop, the `faucet` ties requests to social networks and captcha resolvers. - -Captcha protection uses Google's invisible ReCaptcha, thus the `faucet` needs to run on a live domain.

How does this work?

-

This Ether faucet is running on the {{.Network}} network. To prevent malicious actors from exhausting all available funds or accumulating enough Ether to mount long running spam attacks, requests are tied to common 3rd party social network accounts. Anyone having a Twitter or Facebook account may request funds within the permitted limits.

-
-
-
To request funds via Twitter, make a tweet with your Ethereum address pasted into the contents (surrounding text doesn't matter).
Copy-paste the tweets URL into the above input box and fire away!
- -
-
To request funds via Facebook, publish a new public post with your Ethereum address embedded into the content (surrounding text doesn't matter).
Copy-paste the posts URL into the above input box and fire away!
- - {{if .NoAuth}} -
-
To request funds without authentication, simply copy-paste your Ethereum address into the above input box (surrounding text doesn't matter) and fire away.
This mode is susceptible to Byzantine attacks. Only use for debugging or private networks!

You can track the current pending requests below the input field to see how much you have to wait until your turn comes.

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 2fd1f2855..6447f3c1f 100644 --- a/log/format.go +++ b/log/format.go @@ -2,85 +2,26 @@ 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 ( timeFormat = "2006-01-02T15:04:05-0700" - termTimeFormat = "01-02|15:04:05.000" floatFormat = 'f' termMsgJust = 40 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/ethereum/go-ethereum/", -} - -// 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.
