  • Upgrade CGSpace (linode18) to Ubuntu 18.04:
    • Check any packages that have residual configs and purge them:
    • # dpkg -l | grep -E ‘^rc’ | awk ‘{print $2}’ | xargs dpkg -P
    • Make sure all packages are up to date and the package manager is up to date, then reboot:
# apt update && apt full-upgrade
# apt-get autoremove && apt-get autoclean
# dpkg -C
# reboot
  • Take some backups:
# dpkg -l > 2019-12-01-linode18-dpkg.txt
# tar czf 2019-12-01-linode18-etc.tar.gz /etc
  • Then check all third-party repositories in /etc/apt to see if everything using “xenial” has packages available for “bionic” and then update the sources:
  • # sed -i ‘s/xenial/bionic/’ /etc/apt/sources.list.d/*.list
  • Pause the Uptime Robot monitoring for CGSpace
  • Make sure the update manager is installed and do the upgrade:
# apt install update-manager-core
# do-release-upgrade
  • After the upgrade finishes, remove Java 11, force the installation of bionic nginx, and reboot the server:
# apt purge openjdk-11-jre-headless
# apt install 'nginx=1.16.1-1~bionic'
# reboot
  • After the server comes back up, remove Python virtualenvs that were created with Python 3.5 and re-run certbot to make sure it's working:
# rm -rf /opt/eff.org/certbot/venv/bin/letsencrypt
# rm -rf /opt/ilri/dspace-statistics-api/venv
# /opt/certbot-auto
  • Clear Ansible's fact cache and re-run the playbooks to update the system's firewalls, SSH config, etc
  • Altmetric finally responded to my question about Dublin Core fields
    • They shared a list of fields they use for tracking, but it only mentions HTML meta tags, and not fields considered when harvesting via OAI
    • Anyways, there might be some areas we can improve on the HTML meta tags, if I look at one item with a DOI, ISSN, etc I see that we could at least add status (Open Access) and journal title
    • I merged a pull request into the 5_x-prod branch to add status and journal title to the XHTML meta tags

  • Raise the issue of old, low-quality thumbnails with Peter and the CGSpace team
    • I suggested that we move manually uploaded thumbnails from the ORIGINAL bundle to the THUMBNAIL bundle
    • Also replace old thumbnails where an item is available on Slideshare or YouTube because those are easy to get new, high-quality thumbnails for
  • Continue testing CG Core v2 implementation on DSpace Test
    • Compare the OAI QDC representation of a few items on CGSpace vs DSpace Test:
$ http 'https://cgspace.cgiar.org/oai/request?verb=GetRecord&metadataPrefix=oai_dc&identifier=oai:cgspace.cgiar.org:10568/104030' > /tmp/cgspace-104030.xml
$ http 'https://dspacetest.cgiar.org/oai/request?verb=GetRecord&metadataPrefix=oai_dc&identifier=oai:cgspace.cgiar.org:10568/104030' > /tmp/dspacetest-104030.xml
  • The DSpace Test ones actually now capture the DOI, where the CGSpace doesn't…
  • And the DSpace Test one doesn't include review status as dc.description, but I don't think that's an important field

  • Peter noticed that there were about seventy items on CGSpace that were marked as private
    • Some have been withdrawn, but I extracted a list of the forty-eight that were not:
dspace=# \COPY (SELECT handle, owning_collection FROM item, handle WHERE item.discoverable='f' AND item.in_archive='t' AND handle.resource_id = item.item_id) to /tmp/2019-12-04-CGSpace-private-items.csv WITH CSV HEADER;
COPY 48

  • Enrico noticed that the AReS Explorer on CGSpace (linode18) was down
    • I only see HTTP 502 in the nginx logs on CGSpace… so I assume it's something wrong with the AReS server
    • I ran all system updates on the AReS server (linode20) and rebooted it
    • After rebooting the Explorer was accessible again

2019-12-09

  • Update PostgreSQL JDBC driver to version 42.2.9 in Ansible playbooks
    • Deploy on DSpace Test (linode19) to test before deploying on CGSpace in a few days
  • Altmetric responded to my question about the WLE item that has a lower score than its DOI
    • They say that they will “reprocess” the item “before Christmas”

  • Post message to Yammer about good practices for thumbnails on CGSpace
    • On the topic of thumbnails, I'm thinking we might want to force regenerate all PDF thumbnails on CGSpace since we upgraded it to Ubuntu 18.04 and got a new ghostscript…
  • More discussion about report formats for AReS
  • Peter noticed that the Atmire reports weren't showing any statistics before 2019
    • I checked and indeed Solr had an issue loading some core last time it was started
    • I restarted Tomcat three times before all cores came up successfully
  • While I was restarting the Tomcat service I upgraded the PostgreSQL JDBC driver to version 42.2.9, which had been deployed on DSpace Test earlier this week
