Inconsistent behavior between LocalStorageHelper and real google storage

[Qi77Qi]

Thanks for stopping by to let us know something could be better!

Please include as much information as possible:

Environment details

• OS: Mac
• Java version: 8
• google-cloud-java version(s):
  val googleStorageNew: ModuleID = "com.google.cloud" % "google-cloud-storage" % "1.53.0"
  val googleStorageLocal: ModuleID = "com.google.cloud" % "google-cloud-nio" % "0.71.0-alpha" % "test"

Steps to reproduce

Code is in scala

val page = db.list(bucketName.value, BlobListOption.prefix(objectNamePrefix), BlobListOption.pageSize(1), BlobListOption.currentDirectory())

if db is LocalStorageHelper, page.iterateAll() only gives me one page of object; if db is com.google.cloud.storage.Storage, then page.iterateAll will indeed give me multiple pages as documented.

@Qi77Qi Would you please add a code snippet with LocalStorageHelper class.

Hi @andrewsg , I have a unit test looks like this

  it should "retrieve multiple pages" in ioAssertion {
    val bucketName = genGcsBucketName.sample.get
    val prefix = Gen.uuid.sample.get.toString
    val blobNameWithPrefix = Gen.listOfN(4, genGcsBlobName).sample.get.map(x => GcsBlobName(s"$prefix${x.value}"))
    val objectBody = genGcsObjectBody.sample.get
    for {
      _ <- blobNameWithPrefix.parTraverse(obj => localStorage.storeObject(bucketName, obj, objectBody, objectType))
      allObjectsWithPrefix <- localStorage.unsafeListObjectsWithPrefix(bucketName, prefix, 1)
    } yield {
      allObjectsWithPrefix.map(_.value) should contain theSameElementsAs (blobNameWithPrefix.map(_.value))
    }
  }

There might be too much scala details, but I hope conceptually this makes sense. here is link to github repo if it helps

Hi @andrey-qlogic , thanks for fixing this. Do you know when the fix will be in a release?
