We change the main exporter to be stored and fetched using atomics rather than aquiring a mutex for a mild (but significant in the disabled case) speedup. Also has the benefit of not holding a global lock over all telemetry operations. benchstat of logging benchmatks before and after: name old time/op new time/op delta Baseline-8 329ns ± 2% 327ns ± 2% ~ (p=0.181 n=19+17) LoggingNoExporter-8 3.08µs ± 3% 2.42µs ± 2% -21.42% (p=0.000 n=20+19) Logging-8 13.7µs ± 2% 13.2µs ± 1% -3.49% (p=0.000 n=19+19) LoggingStdlib-8 5.39µs ± 3% 5.41µs ± 2% ~ (p=0.177 n=19+20) This is a replacement for https://go-review.googlesource.com/c/tools/+/212244 but built on the single exporter principle rather than the exporter list.

Go Tools
This subrepository holds the source for various packages and tools that support the Go programming language.
Some of the tools, godoc
and vet
for example, are included in binary Go
distributions.
Others, including the Go guru
and the test coverage tool, can be fetched with
go get
.
Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.
Download/Install
The easiest way to install is to run go get -u golang.org/x/tools/...
. You can
also manually git clone the repository to $GOPATH/src/golang.org/x/tools
.
