Building Badger without Cgo fails because of references to Zstd in table/builder.go introduced in #1459 . $ CGO_ENABLED=0 go build -v . github.com/DataDog/zstd go build github.com/DataDog/zstd: build constraints exclude all Go files in /home/dmai/go/pkg/mod/github.com/!data!dog/[email protected] Moving zstd.CompressBound to y/zstd_cgo.go and y/zstd_nocgo.go fixes non-Cgo builds. As is already the case, non-Cgo builds with compression must use snappy, not Zstd, or calling y.ZSTDCompressBound without Cgo will panic.
