Releases: ipfs/go-log
v2.9.0
The Problem
go-libp2p 0.44 switched from go-log to slog, which broke visibility of go-libp2p logs for applications using go-log. Applications could no longer see go-libp2p logs or adjust their levels at runtime (see kubo#11035).
go-libp2p maintainers evaluated two options presented by Kubo maintainers for addressing this (details): fix the breaking change in go-libp2p, or require each application to add integration code. The manual integration approach was selected.
The Fix
This release adds SlogHandler() to bridge slog-based libraries back into go-log. Applications using go-log (>=2.9)+go-libp2p(>=0.45) need to add this to their init():
import (
"log/slog"
golog "github.com/ipfs/go-log/v2"
"github.com/libp2p/go-libp2p/gologshim"
)
func init() {
// Route all slog logs through go-log
slog.SetDefault(slog.New(golog.SlogHandler()))
// Connect go-libp2p to go-log
gologshim.SetDefaultHandler(golog.SlogHandler())
}After adding this:
- go-libp2p logs appear in application output again
SetLogLevel("libp2p-swarm", "debug")works again- logs can be piped to dynamically created sinks, like
ipfs log tail - All logs use go-log's formatting (JSON/color/nocolor)
More Info
See the README: Slog integration for details.
