# This little gist calculates the md5sum as the aws/s3 does.
# Either use a non-zero chunk size to specify the chunk size used while
# uploading the file, or just don't specify it if you didn't do
# a multipart upload.

# To have an example of how to get an aws etag, see:

# This little gist returns the checksum of and aws file.
# This can be the checksum of the file or, if the file has been uploaded in a
# multipart format, it's the checksum of the binary concatenation of the
# checkusms of the chunks of the multiparts followed by the number of chunks of
# the multipart object.
#
# Tested with aws-sdk-v1 gem.

# This gist tries to guess the chunk size in Megabytes of a multipart upload of
# an AWS file using its local copy and the etag of the remote file.
# Here we suppose the chunk size chosen for the upload is an integer in Megabytes.
#
# To run correctly, it requires the `get_etag` function from
# https://gist.github.com/aerostitch/538eda0b2d1d8dd914bf
#
# You can get the etag of the remote file by using the `get_AWS_file_checksum` function

# This gist checks if an AWS file's etag matches any of the checksum of its local copy,

# Description
#   This script's purpose is to test the response time on a url
#   by doing a simple curl loop (no pause, so a bit hammering).
#   It returns the several curl metrics in a csv file for further analysis.
