cache

Extracted from go/src/cmd/go/internal/cache/.

The main modifications are:

• The errors management
  • Some methods return error.
  • Some errors are returned instead of being ignored.
• The name of the env vars:
  • GOCACHE -> GOLANGCI_LINT_CACHE
  • GOCACHEPROG -> GOLANGCI_LINT_CACHEPROG

Previous History

Based on the initial PR/commit the based in a mix between go1.12 and go1.13:

• cache.go (go1.13)
• cache_test.go (go1.12?)
• default.go (go1.12?)
• hash.go (go1.13 and go1.12 are identical)
• hash_test.go -> (go1.12?)

Adapted for golangci-lint:

• https://github.com/golangci/golangci-lint/pull/699: initial code (contains modifications of the files)
• https://github.com/golangci/golangci-lint/pull/779: just a nolint (cache.go)
• https://github.com/golangci/golangci-lint/pull/788: only directory permissions changes (0777 -> 0744) (cache.go, cache_test.go, default.go)
• https://github.com/golangci/golangci-lint/pull/808: mainly related to logs and errors (cache.go, default.go, hash.go, hash_test.go)
• https://github.com/golangci/golangci-lint/pull/1063: ioutil -> robustio (cache.go)
• https://github.com/golangci/golangci-lint/pull/1070: add t.Parallel() inside cache_test.go
• https://github.com/golangci/golangci-lint/pull/1162: errors inside cache.go
• https://github.com/golangci/golangci-lint/pull/2318: ioutil -> os (cache.go, cache_test.go, default.go, hash_test.go)
• https://github.com/golangci/golangci-lint/pull/2352: Go doc typos
• https://github.com/golangci/golangci-lint/pull/3012: errors inside cache.go (cache.go, default.go)
• https://github.com/golangci/golangci-lint/pull/3196: constant for GOLANGCI_LINT_CACHE (cache.go)
• https://github.com/golangci/golangci-lint/pull/3204: add this file and %w in fmt.Errorf (cache.go)
