| # https://golang.org/issue/46141: 'go mod tidy' for a Go 1.17 module should by |
| # default preserve enough checksums for the module to be used by Go 1.16. |
| # |
| # We don't have a copy of Go 1.16 handy, but we can simulate it by editing the |
| # 'go' version in the go.mod file to 1.16, without actually updating the |
| # requirements to match. |
| |
| [short] skip |
| |
| env MODFMT='{{with .Module}}{{.Path}} {{.Version}}{{end}}' |
| |
| |
| # For this module, the "deleted" dependency contains an imported package, but |
| # Go 1.16 selects a higher version (in which that package has been deleted). |
| |
| cp go.mod go.mod.orig |
| |
| ! go mod tidy |
| |
| stderr '^example\.com/m imports\n\texample\.net/deleted loaded from example\.net/deleted@v0\.1\.0,\n\tbut go 1\.16 would fail to locate it in example\.net/deleted@v0\.2\.0\n\n' |
| |
| stderr '\n\nTo upgrade to the versions selected by go 1.16, leaving some packages unresolved:\n\tgo mod tidy -e -go=1\.16 && go mod tidy -e -go=1\.17\nIf reproducibility with go 1.16 is not needed:\n\tgo mod tidy -compat=1\.17\nFor other options, see:\n\thttps://golang\.org/wiki/PruningModules\n' |
