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.

upload_part_thread = threading.Thread(target=self.upload_part,
args=(1,))
# Once this thread starts it will immediately block.
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.
complete_upload_thread = threading.Thread(target=self.complete_upload)
self.start_thread(complete_upload_thread)
# Then finally the CreateMultipartUpload completes and we
# announce the upload id.

# The complete upload thread should still be waiting for an expect
# parts number.

def test_randomized_stress_test(self):
# 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.
