From b2f2446b46bf02821d90ebedadae2bf7ae0e880e Mon Sep 17 00:00:00 2001 From: Taras Madan Date: Mon, 5 Sep 2022 14:27:54 +0200 Subject: go.mod, vendor: update (#3358) * go.mod, vendor: remove unnecessary dependencies Commands: 1. go mod tidy 2. go mod vendor * go.mod, vendor: update cloud.google.com/go Commands: 1. go get -u cloud.google.com/go 2. go mod tidy 3. go mod vendor * go.mod, vendor: update cloud.google.com/* Commands: 1. go get -u cloud.google.com/storage cloud.google.com/logging 2. go mod tidy 3. go mod vendor * go.mod, .golangci.yml, vendor: update *lint* Commands: 1. go get -u golang.org/x/tools github.com/golangci/golangci-lint@v1.47.0 2. go mod tidy 3. go mod vendor 4. edit .golangci.yml to suppress new errors (resolved in the same PR later) * all: fix lint errors hash.go: copy() recommended by gosimple parse.go: ent is never nil verifier.go: signal.Notify() with unbuffered channel is bad. Have no idea why. * .golangci.yml: adjust godot rules check-all is deprecated, but still work if you're hesitating too - I'll remove this commit --- vendor/github.com/hexops/gotextdiff/span/uri.go | 169 ++++++++++++++++++++++++ 1 file changed, 169 insertions(+) create mode 100644 vendor/github.com/hexops/gotextdiff/span/uri.go (limited to 'vendor/github.com/hexops/gotextdiff/span/uri.go') diff --git a/vendor/github.com/hexops/gotextdiff/span/uri.go b/vendor/github.com/hexops/gotextdiff/span/uri.go new file mode 100644 index 000000000..250492135 --- /dev/null +++ b/vendor/github.com/hexops/gotextdiff/span/uri.go @@ -0,0 +1,169 @@ +// Copyright 2019 The Go Authors.
