Use multiple caches, do not go back to origin

Features:

• Use 4 caches for both XRootD and HTTP transfer
• Never go back to the origin

Support Python 3

This release adds support for Python 3. It also changes the statistics collector to collector.atlas-ml.org.

Add cache location in /etc

This release adds back checking for stashcache caches.json in /etc.

Downloadable list of Caches

In this release, we modified how caches are detected. A list of caches is downloaded from a globally available network of nodes. This should make updating the cache list an automated process without needing a new release of StashCache.

from python module to package

Few changes to both the layout of the files and the installer script setup.py were carried out so that it can be installed as a python package instead of a module.

Better SciTokens support

v5.4.1

Bump to 5.4.1

New SciToken Disk Format

HTTP Support

In this release, we allow

Also, you can now specify how you want the file downloaded, for example:

stashcp --methods=cvmfs,http,xrootd /user/...

Improved GeoIP

In this release, we change the GeoIP servers used for looking up the nearest StashCache caches. Additionally, we improve the logic of querying GeoIP servers only when needed.

Writeback Release

In this release, we add writeback capabilities. They utilize SciTokens in order to authenticate with the writeback host on the Stash filesystem.

The syntax for writeback is:

stashcp <local_file> stash:///user/<username>/blah
