#17794 Go backend tolerates missing `go.sum` entries Issue created by tdyas While testing the Cgo fixes from #17592, I noticed that Pants was tolerating missing

go.sum

entries for the third party dependency under test. Fortunately, Pants and Go still error out if an inconsistent

go.sum

entry is present. I tested that by running

go mod download

to update

go.sum

and then editing an entry in

go.sum

to be intentionally wrong; a build then failed as expected due to the checksum mismatch. The

go

toolchain will mutate

go.sum

to add missing

go.sum

entries. Pants should either do that or detect when such mutation is necessary and error instead of silently allowing the situation. I suspect that

go

is modifying the copy of

go.sum

present in an execution sandbox but Pants is not detecting when such modification occurs. pantsbuild/pants
