示例1: TestMultipartUploadContext

# 需要导入模块: from awscli.customizations.s3.tasks import MultipartUploadContext [as 别名]
# 或者: from awscli.customizations.s3.tasks.MultipartUploadContext import announce_total_parts [as 别名]

#.........这里部分代码省略.........

    def test_streaming_threaded_parts(self):
        # This is similar to the basic threaded parts test but instead
        # the thread has to wait to know exactly how many parts are 
        # expected from the stream.  This is indicated when the expected
        # parts of the context changes from ... to an integer.

        self.context = MultipartUploadContext(expected_parts='...')
        upload_part_thread = threading.Thread(target=self.upload_part,
                                              args=(1,))

        self.start_thread(upload_part_thread)

        # Also, let's start the thread that will do the complete
        # multipart upload.  It will also block because it needs all
        # the parts so it's blocked up the upload_part_thread.  It also
        # needs the upload_id so it's blocked on that as well.

        # parts number.

        # waiting to announce the parts.
        self.assertFalse(was_completed)        

        # We can verify that the invariants still hold.

        # Now given that we've verified the functionality from
        # the two tests above, we randomize the threading to ensure
        # that the order doesn't actually matter.  The invariant that
        # the CreateMultipartUpload is called first, then UploadPart
        # operations are called with the appropriate upload_id, then
        # CompleteMultipartUpload with the appropriate upload_id and
        # parts list should hold true regardless of how the threads
        # are ordered.
