Check your files into the bucket “chromium-telemetry”

Put the target file in the directory you want it to be when downloaded from Cloud Storage, say /path/to/target. Use this command to upload:

depot_tools/upload_to_google_storage.py --bucket chromium-telemetry /path/to/target

A SHA1 file /path/to/target.sha1 will be generated for each uploaded file.

You may run the following command for more usage.

depot_tools/upload_to_google_storage.py -h

Check the .sha1 files into repository

svn add /path/to/target.sha1

svn rm /path/to/target  # If the file was previously in the repo.

or

git add /path/to/target.sha1

git rm /path/to/target  # If the file was previously in the repo.

Download the file in python

from telemetry.page import cloud_storage

cloud_storage.GetIfChanged(cloud_storage.CHROMIUM_TELEMETRY_BUCKET,

                                           '/path/to/target')
