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	12 months ago

Martin Holst Swende	233db64cc1	all: make vendored copy of reexec (#28382) ... a little copying is better than a little dependency -- go proverb We have this dependency on docker, a.k.a moby: a gigantic library, and we only need ~70 LOC, so here I tried moving it inline instead.

Martin Holst Swende	58ae1df684	cmd/geth: test for logging-output (#28373) ... This PR is a bit in preparation for the slog work in #28187 . Our current test re logging mostly test the internals, but we have no real end-to-end test of the logging output. This PR introduces a simple reexec-based log tester. This also relies upon a special mode in geth, which can be made to eject a set of predefined log messages (only available if the build-tag `integrationtests` is used e.g. go run --tags=integrationtests ./cmd/geth --log.format terminal logtest While working on this, I also noticed a quirk in the setup: when geth was configured to use a file output, then two separate handlers were used (one handler for the file, one handler for the console). Using two separate handlers means that two formatters are used, thus the formatting of any/all records happened twice. This PR changes the mechanism to use two separate io.Writers instead, which is both more optimal and fixes a bug which occurs due to a global statefulness in the formatter.	1 year ago
