Updating non indexed field of doc with unique index fails

[fredcarle]

Updating unique indexed field on a given doc succeeds but updating a non indexed field of a doc with a unique index fails. The following should succeed but it fails with the error:

can not index a doc's field(s) that violates unique index. DocID: bae-b0a35b3c-486b-54fc-8736-eeff036414ef, name: Fred.

func TestUniqueIndexUpdate_UponUpdatingDocNonIndexedField_ShouldSucceed(t *testing.T) {
	test := testUtils.TestCase{
		Actions: []any{
			testUtils.SchemaUpdate{
				Schema: `
					type User {
						name: String @index(unique: true)
						age: Int
					}
				`,
			},
			testUtils.CreateDoc{
				CollectionID: 0,
				Doc: `
					{
						"name":	"Fred",
						"age":	36
					}`,
			},
			testUtils.UpdateDoc{
				CollectionID: 0,
				DocID:        0,
				Doc: `
					{
						"age":	37
					}`,
			},
		},
	}

	testUtils.ExecuteTestCase(t, test)
}

There is also a similar behaviour for composite indexes where the following should succeed but fails with the error:

can not index a doc's field(s) that violates unique index. DocID: bae-cae3deac-d371-5a1f-93b4-ede69042f79b, name: John, age: 21

func TestUniqueCompositeIndexUpdate_UponUpdatingDocWithExistingFieldValue_ShouldSucceed(t *testing.T) {
	test := testUtils.TestCase{
		Actions: []any{
			testUtils.SchemaUpdate{
				Schema: `
					type User @index(unique: true, fields: ["name", "age"]) {
						name: String 
						age: Int 
						email: String
					}
				`,
			},
			testUtils.CreateDoc{
				CollectionID: 0,
				Doc: `
					{
						"name":	"John",
						"age":	21,
						"email": "email@gmail.com"
					}`,
			},
			testUtils.UpdateDoc{
				CollectionID: 0,
				DocID:        0,
				Doc: `
					{
						"email": "another@gmail.com"
					}`,
			},
		},
	}

	testUtils.ExecuteTestCase(t, test)
}
