tiancaiamao	32b1dbd8d5	*: rename "github.com/pkg/errors" to "github.com/pingcap/errors" (#8136) ... We import "github.com/pkg/errors" in the code, and actually put the "github.com/pingcap/errors" there in the vendor path. That's a dirty hack, and prevent the introduce of Go module.	2018-11-01 16:09:07 +08:00
