Code
e.g.
func main() {
ctx, cancel := context.WithCancel(context.Background())
client, _ := spanner.NewClient(ctx, "path to db")
_, err = client.ReadWriteTransaction(ctx, func(ctx context.Context, tx *spanner.ReadWriteTransaction) error {
iter := tx.Query(ctx, spanner.NewStatement("SELECT 1"))
if _, err := iter.Next(); err != nil {
return err
}
return nil
})
if err != nil {
panic(err)
}
cancel() // cancel here
_, err = client.ReadWriteTransaction(ctx, func(ctx context.Context, tx *spanner.ReadWriteTransaction) error {
iter := tx.Query(ctx, spanner.NewStatement("SELECT 1"))
if _, err := iter.Next(); err != nil {
return err
}
return nil
})
if err != nil {
if status.Code(err) == codes.Canceled {
fmt.Println("expected")
} else {
fmt.Printf("Unexpected err: %v", err)
}
}
}Expected behavior
print expected
Actual behavior
Unexpected err: spanner: code = "Internal", desc = "error while BeginTransaction during retrying a ReadWrite transaction: spanner: code = \"Canceled\", desc = \"context canceled\""
Additional context
It happens after #7149 is merged.
