Bulk kv backend registration fails

[ermik]

kv.List() called here:

cayley/graph/kv/registry.go

Line 11 in b9dabbe

for _, r := range kv.List() {

returns an empty array.

The list of imports (modules are "GOFLAGS": "-mod=vendor") declared in client package used for testing:

import (
	"github.com/cayleygraph/cayley"
	"github.com/cayleygraph/cayley/graph"
	"github.com/cayleygraph/cayley/graph/path"
	"github.com/cayleygraph/cayley/schema"
	"github.com/cayleygraph/quad"
	"github.com/cayleygraph/quad/voc"

	// The drivers for cayley
	_ "github.com/cayleygraph/cayley/graph/kv" // "all"
	bg "github.com/cayleygraph/cayley/graph/kv/bolt"
	lg "github.com/cayleygraph/cayley/graph/kv/leveldb"

	// Init "single" writer; unnecessary when using cayley.Handle, here for verbosity.
	_ "github.com/cayleygraph/cayley/writer"

	// Import RDF vocabulary definitions to be able to expand IRIs like rdf:label.
	_ "github.com/cayleygraph/quad/voc/core"
)

The order of those imports is important. I think you should import kv/bolt before kv.
