web application with the goal of distributing small amounts of Ether in private and test networks. - -Users need to post their Ethereum addresses to fund in a Twitter status update or public Facebook post and share the link to the faucet. The faucet will in turn deduplicate user requests and send the Ether. After a funding round, the faucet prevents the same user from requesting again for a pre-configured amount of time, proportional to the amount of Ether requested. - -## Operation - -The `faucet` is a single binary app (everything included) with all configurations set via command line flags and a few files. - -First things first, the `faucet` needs to connect to an Ethereum network, for which it needs the necessary genesis and network infos. Each of the following flags must be set: - -- `-genesis` is a path to a file containing the network `genesis.json`. or using: - - `-goerli` with the faucet with Görli network config - - `-sepolia` with the faucet with Sepolia network config -- `-network` is the devp2p network id used during connection -- `-bootnodes` is a list of `enode://` ids to join the network through - -The `faucet` will use the `les` protocol to join the configured Ethereum network and will store its data in `$HOME/.faucet` (currently not configurable). - -## Funding - -To be able to distribute funds, the `faucet` needs access to an already funded Ethereum account. 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. The domain needs to be registered in Google's systems to retrieve the captcha API token and secrets. After doing so, captcha protection may be enabled via: - -- `-captcha.token` is the API token for ReCaptcha -- `-captcha.secret` is the API secret for ReCaptcha - -Sybil protection via Twitter requires an API key as of 15th December, 2020. To obtain it, a Twitter user must be upgraded to developer status and a new Twitter App deployed with it. The app's `Bearer` token is required by the faucet to retrieve tweet data: - -- `-twitter.token` is the Bearer token for `v2` API access -- `-twitter.token.v1` is the Bearer token for `v1` API access - -Sybil protection via Facebook uses the website to directly download post data thus does not currently require an API configuration. - -## Miscellaneous - -Beside the above - mostly essential - CLI flags, there are a number that can be used to fine-tune the `faucet`'s operation. Please see `faucet --help` for a full list. diff --git a/cmd/faucet/faucet.go b/cmd/faucet/faucet.go deleted file mode 100644 index e4d6ad6977..0000000000 --- a/cmd/faucet/faucet.go +++ /dev/null @@ -1,891 +0,0 @@ -// Copyright 2017 The go-ethereum Authors -// This file is part of go-ethereum. -// -// go-ethereum is free software: you can redistribute it and/or modify -// it under the terms of the GNU General Public License as published by -// the Free Software Foundation, either version 3 of the License, or -// (at your option) any later version. -// -// go-ethereum is distributed in the hope that it will be useful, -// but WITHOUT ANY WARRANTY; without even the implied warranty of -// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

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.

Changelog + +All notable changes to the tracing interface will be documented in this file. + +## [Unreleased] + +There have been minor backwards-compatible changes to the tracing interface to explicitly mark the execution of **system** contracts. As of now the only system call updates the parent beacon block root as per [EIP-4788](https://eips.ethereum.org/EIPS/eip-4788). Other system calls are being considered for the future hardfork. + +### New methods + +- `OnSystemCallStart()`: This hook is called when EVM starts processing a system call. Note system calls happen outside the scope of a transaction. This event will be followed by normal EVM execution events. +- `OnSystemCallEnd()`: This hook is called when EVM finishes processing a system call. + +## [v1.14.0] + +There has been a major breaking change in the tracing interface for custom native tracers. JS and built-in tracers are not affected by this change and tracing API methods may be used as before. This overhaul has been done as part of the new live tracing feature ([#29189](https://github.com/ethereum/go-ethereum/pull/29189)). To learn more about live tracing please refer to the [docs](https://geth.ethereum.org/docs/developers/evm-tracing/live-tracing). + +**The `EVMLogger` interface which the tracers implemented has been removed.** It has been replaced by a new struct `tracing.Hooks`. `Hooks` keeps pointers to event listening functions. Internally the EVM will use these function pointers to emit events and can skip an event if the tracer has opted not to implement it. In fact this is the main reason for this change of approach. Another benefit is the ease of adding new hooks in future, and dynamically assigning event receivers. + +The consequence of this change can be seen in the constructor of a tracer. Let's take the 4byte tracer as an example. Previously the constructor return an instance which satisfied the interface. Now it should return a pointer to `tracers.Tracer` (which is now also a struct as opposed to an interface) and explicitly assign the event listeners. As a side-benefit the tracers will not have to provide empty implementation of methods just to satisfy the interface: + +```go +func newFourByteTracer(ctx *tracers.Context, _ json.RawMessage) (tracers.Tracer, error) { + t := &fourByteTracer{ + ids: make(map[string]int), + } + return t, nil + +} +``` + +And now: + +```go +func newFourByteTracer(ctx *tracers.Context, _ json.RawMessage) (*tracers.Tracer, error) { + t := &fourByteTracer{ + ids: make(map[string]int), + } + return &tracers.Tracer{ + Hooks: &tracing.Hooks{ + OnTxStart: t.onTxStart, + OnEnter: t.onEnter, + }, + GetResult: t.getResult, + Stop: t.stop, + }, nil +} +``` + +### Event listeners + +If you have sharp eyes you might have noticed the new names for `OnTxStart` and `OnEnter`, previously called `CaptureTxStart` and `CaptureEnter`. Indeed there have been various modifications to the signatures of the event listeners. All method names now follow the `On*` pattern instead of `Capture*`. However the modifications are not limited to the names. + +#### New methods + +The live tracing feature was half about adding more observability into the state of the blockchain. As such there have been a host of method additions. Please consult the [Hooks](./hooks.go) struct for the full list of methods. Custom tracers which are invoked through the API (as opposed to "live" tracers) can benefit from the following new methods: + +- `OnGasChange(old, new uint64, reason GasChangeReason)`: This hook tracks the lifetime of gas within a transaction and its subcalls. It will first track the initial purchase of gas with ether, then the following consumptions and refunds of gas until at the end the rest is returned. +- `OnBalanceChange(addr common.Address, prev, new *big.Int, reason BalanceChangeReason)`: This hook tracks the balance changes of accounts. Where possible a reason is provided for the change (e.g. a transfer, gas purchase, withdrawal deposit etc). +- `OnNonceChange(addr common.Address, prev, new uint64)`: This hook tracks the nonce changes of accounts. +- `OnCodeChange(addr common.Address, prevCodeHash common.Hash, prevCode []byte, codeHash common.Hash, code []byte)`: This hook tracks the code changes of accounts. +- `OnStorageChange(addr common.Address, slot common.Hash, prev, new common.Hash)`: This hook tracks the storage changes of accounts. +- `OnLogChange(log *types.Log)`: This hook tracks the logs emitted by the EVM. + +#### Removed methods + +The hooks `CaptureStart` and `CaptureEnd` have been removed. These hooks signaled the top-level call frame of a transaction. The relevant info will be now emitted by `OnEnter` and `OnExit` which are emitted for every call frame. They now contain a `depth` parameter which can be used to distinguish the top-level call frame when necessary. The `create bool` parameter to `CaptureStart` can now be inferred from `typ byte` in `OnEnter`, i.e. `vm.OpCode(typ) == vm.CREATE`. + +#### Modified methods + +- `CaptureTxStart` -> `OnTxStart(vm *VMContext, tx *types.Transaction, from common.Address)`. It now emits the full transaction object as well as `from` which should be used to get the sender address. The `*VMContext` is a replacement for the `*vm.EVM` object previously passed to `CaptureStart`. +- `CaptureTxEnd` -> `OnTxEnd(receipt *types.Receipt, err error)`. It now returns the full receipt object. +- `CaptureEnter` -> `OnEnter(depth int, typ byte, from common.Address, to common.Address, input []byte, gas uint64, value *big.Int)`. The new `depth int` parameter indicates the call stack depth. It is 0 for the top-level call. Furthermore, the location where `OnEnter` is called in the EVM is now made a soon as a call is started. This means some specific error cases that were not before calling `OnEnter/OnExit` will now do so, leading some transaction to have an extra call traced. +- `CaptureExit` -> `OnExit(depth int, output []byte, gasUsed uint64, err error, reverted bool)`. It has the new `depth` parameter, same as `OnEnter`. The new `reverted` parameter indicates whether the call frame was reverted. +- `CaptureState` -> `OnOpcode(pc uint64, op byte, gas, cost uint64, scope tracing.OpContext, rData []byte, depth int, err error)`. `op` is of type `byte` which can be cast to `vm.OpCode` when necessary. A `*vm.ScopeContext` is not passed anymore. It is replaced by `tracing.OpContext` which offers access to the memory, stack and current contract. +- `CaptureFault` -> `OnFault(pc uint64, op byte, gas, cost uint64, scope tracing.OpContext, depth int, err error)`. Similar to above. + +[unreleased]: https://github.com/ethereum/go-ethereum/compare/v1.14.0...master +[v1.14.0]: https://github.com/ethereum/go-ethereum/releases/tag/v1.14.0 \ No newline at end of file diff --git a/core/tracing/hooks.go b/core/tracing/hooks.go new file mode 100644 index 0000000000..9f9ac313a8 --- /dev/null +++ b/core/tracing/hooks.go @@ -0,0 +1,308 @@ +// Copyright 2024 The go-ethereum Authors +// This file is part of the go-ethereum library. +// +// The go-ethereum library is free software: you can redistribute it and/or modify +// it under the terms of the GNU Lesser General Public License as published by +// the Free Software Foundation, either version 3 of the License, or +// (at your option) any later version. +// +// The go-ethereum library is distributed in the hope that it will be useful, +// but WITHOUT ANY WARRANTY; without even the implied warranty of +// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

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 2fd1f28558..54c071b908 100644 --- a/log/format.go +++ b/log/format.go @@ -2,14 +2,11 @@ package log import ( "bytes" - "encoding/json" "fmt" + "log/slog" "math/big" "reflect" "strconv" - "strings" - "sync" - "sync/atomic" "time" "unicode/utf8" @@ -18,69 +15,13 @@ import ( 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.
