Notes

2020-02-02

  • Continue working on porting CGSpace's DSpace 5 code to DSpace 6.3 that I started yesterday
    • Sign up for an account with MaxMind so I can get the GeoLite2-City.mmdb database
    • I still need to wire up the API credentials and cron job into the Ansible infrastructure playbooks
    • Fix some minor issues in the config and XMLUI themes, like removing Atmire stuff
    • The code finally builds and runs with a fresh install
  • Now we don't specify the build environment because site modification are in local.cfg, so we just build like this:
$ schedtool -D -e ionice -c2 -n7 nice -n19 mvn -U -Dmirage2.on=true -Dmirage2.deps.included=false clean package
  • And it seems that we need to enabled pg_crypto now (used for UUIDs):
$ psql -h localhost -U postgres dspace63
dspace63=# CREATE EXTENSION pgcrypto;
CREATE EXTENSION pgcrypto;
  • I tried importing a PostgreSQL snapshot from CGSpace and had errors due to missing Atmire database migrations
    • If I try to run dspace database migrate I get the IDs of the migrations that are missing
    • I delete them manually in psql:
dspace63=# DELETE FROM schema_version WHERE version IN ('5.0.2015.01.27', '5.6.2015.12.03.2', '5.6.2016.08.08', '5.0.2017.04.28', '5.0.2017.09.25', '5.8.2015.12.03.3');
  • Then I ran dspace database migrate and got an error:
$ ~/dspace63/bin/dspace database migrate

Database URL: jdbc:postgresql://localhost:5432/dspace63?ApplicationName=dspaceCli
Migrating database to latest version... (Check dspace logs for details)

  • I think I might need to update the sequences first... nope
  • Perhaps it's due to some missing bitstream IDs and I need to run dspace cleanup on CGSpace and take a new PostgreSQL dump... nope
  • A thread on the dspace-tech mailing list regarding this migration noticed that his database had some views created that were using the resource_id column
  • Our database had the same issue, where the eperson_metadata view was created by something (Atmire module?) but has no references in the vanilla DSpace code, so I dropped it and tried the migration again:
dspace63=# DROP VIEW eperson_metadata;
DROP VIEW
  • After that the migration was successful and DSpace starts up successfully and begins indexing
    • xmlui, solr, jspui, and oai are working, but rest is not starting up (turns out rest was working, but it was redirecting to HTTPS... I wonder why, because it wasn't doing that on DSpace 5!)
    • I started diffing our themes against the Mirage 2 reference theme to capture the latest changes
