Alan Orth	819f8e6b0d	Add build.yml for sr.ht Trying to figure out how to run builds on this new platform. See: https://man.sr.ht/builds.sr.ht/#build-manifests	2019-02-07 17:09:48 +02:00
Alan Orth	c79e50a364	README.md: Add TODO about DSpace 6 UUIDs I'm not sure how this will affect us, especially if we want to keep support for DSpace 4, 5, and 6 in the same code base. At least the REST API endpoint will have to change from an integer, our database schema will have to change depending on whether the repository is using IDs or UUIDs, and maybe even the Solr queries will change.	2019-02-07 16:52:36 +02:00

Alan Orth	40e284dac0	dspace_statistics_api/indexer.py: Query multiple shards DSpace's stats-util script splits the Solr statistics core into yearly shards. We need to use Solr's `shards` query parameter in order to get the statistics for previous years. This commit adds a helper function to enumerate the active Solr cores to find yearly shards matching the statistics-YYYY pattern and add them to the query.	2019-01-22 08:39:36 +02:00
