Martin Holst Swende	b8d44ed98b	log: remove lazy, remove unused interfaces, unexport methods (#28622) ... This change - Removes interface `log.Format`, - Removes method `log.FormatFunc`, - unexports `TerminalHandler.TerminalFormat` formatting methods (renamed to `TerminalHandler.format`) - removes the notion of `log.Lazy` values The lazy handler was useful in the old log package, since it could defer the evaluation of costly attributes until later in the log pipeline: thus, if the logging was done at 'Trace', we could skip evaluation if logging only was set to 'Info'. With the move to slog, this way of deferring evaluation is no longer needed, since slog introduced 'Enabled': the caller can thus do the evaluate-or-not decision at the callsite, which is much more straight-forward than dealing with lazy reflect-based evaluation. Also, lazy evaluation would not work with 'native' slog, as in, these two statements would be evaluated differently: ```golang log.Info("foo", "my lazy", lazyObj) slog.Info("foo", "my lazy", lazyObj) ```	12 months ago
jwasinger	28e7371701	all: replace log15 with slog (#28187) ... This PR replaces Geth's logger package (a fork of [log15](https://github.com/inconshreveable/log15)) with an implementation using slog, a logging library included as part of the Go standard library as of Go1.21. Main changes are as follows: * removes any log handlers that were unused in the Geth codebase. * Json, logfmt, and terminal formatters are now slog handlers. * Verbosity level constants are changed to match slog constant values. Internal translation is done to make this opaque to the user and backwards compatible with existing `--verbosity` and `--vmodule` options. * `--log.backtraceat` and `--log.debug` are removed. The external-facing API is largely the same as the existing Geth logger. Logger method signatures remain unchanged. A small semantic difference is that a `Handler` can only be set once per `Logger` and not changed dynamically. This just means that a new logger must be instantiated every time the handler of the root logger is changed. ---- For users of the `go-ethereum/log` module. If you were using this module for your own project, you will need to change the initialization. If you previously did ```golang log.Root().SetHandler(log.LvlFilterHandler(log.LvlInfo, log.StreamHandler(os.Stderr, log.TerminalFormat(true)))) ``` You now instead need to do ```golang log.SetDefault(log.NewLogger(log.NewTerminalHandlerWithLevel(os.Stderr, log.LevelInfo, true))) ``` See more about reasoning here: https://github.com/ethereum/go-ethereum/issues/28558#issuecomment-1820606613	1 year ago
Martin Holst Swende	b77a9b127c	cmd/geth: more testcases for logging (#28501) ... * cmd/geth: more testcases for logging This adds more edgecases around logging, particularly around handling of different types of nil-values as concrete types and within interfaces. Also adds tests with 'reserved' values which breaks json/logfmt formats. The json output is checked in, but not actively used by any testcase at the moment. * cmd/geth/testdata: remove timestamps	1 year ago
