This brings in the upstream fix
1aadbdfdbb. (Upstream
issue is https://github.com/golang/go/issues/31163).
To create this commit, I did:
vgo get golang.org/x/tools
make update_deps
cd cmd/golangci-lint
go install -ldflags "-X 'main.version=$(git describe --tags)' -X 'main.commit=$(git rev-parse --short HEAD)' -X 'main.date=$(date)'"
Fixes#500
This updates the unparam linter to the current version that has fewer
false positives. The go.{mod,sum} files and the vendor folder are
updated as follows:
export GO111MODULE=on
go get -u mvdan.cc/unparam
go mod tidy
go mod vendor
The unparam callgraph algorithm is no longer selectable. Ref:
https://github.com/mvdan/unparam/commit/e6a6d1c5
This is the reason for removing the c.CallgraphAlgorithm(us.Algo) line
from pkg/golinters/unparam.go.
Use go/packages instead of x/tools/loader: it allows to work
with go modules and speedups loading of packages with the help
of build cache.
A lot of linters became "fast": they are enabled by --fast now and
work in 1-2 seconds. Only unparam, interfacer and megacheck
are "slow" linters now.
Average project is analyzed 20-40% faster than before if all linters are
enabled! If we enable all linters except unparam, interfacer and
megacheck analysis is 10-20x faster!
