There was a problem hiding this comment.
The barrier only expects one key is locked. So the change makes sense to me.
// WithFirstKey gets the lexically first key in the request range.
func WithFirstKey() []OpOption { return withTop(SortByKey, SortAscend) }
// withTop gets the first key over the get's prefix given a sort order
func withTop(target SortTarget, order SortOrder) []OpOption {
return []OpOption{WithPrefix(), WithSort(target, order), WithLimit(1)}
}
Could you add a test in https://github.com/etcd-io/etcd/blob/main/tests/integration/clientv3/experimental/recipes/v3_barrier_test.go?

Overall looks good to me. Please resolve the minor comment above, and also squash the commits. |
fix the unexpected blocking when using Barrier.Wait(), e.g. NewBarrier(client, "a").Wait() will block if key "a" is not existed but "a0" is existed, but it should return immediately. Signed-off-by: zhangwenkang <zwenkang@vmware.com>
