Documenting day-to-day work on the CGSpace repository.

  • Help CCAFS with regenerating some item thumbnails after they uploaded new PDFs to some items on CGSpace
  • A user on the dspace-tech mailing list offered some suggestions for troubleshooting the problem with the inability to delete certain items
    • Apparently if the item is in the workflowitem table it is submitted to a workflow
    • And if it is in the workspaceitem table it is in the pre-submitted state
  • The item seems to be in a pre-submitted state, so I tried to delete it from there:
dspace=# DELETE FROM workspaceitem WHERE item_id=74648;
DELETE 1
  • But after this I tried to delete the item from the XMLUI and it is still present…

  • Meeting with AgroKnow to discuss CGSpace, ILRI data, AReS, GARDIAN, etc
    • They asked if we had plans to enable RDF support in CGSpace
  • There have been 4,400 more downloads of the CTA Spore publication from those strange Amazon IP addresses today
    • I suspected that some might not be successful, because the stats show less, but today they were all HTTP 200!
# cat /var/log/nginx/access.log /var/log/nginx/access.log.1 | grep 'Spore-192-EN-web.pdf' | grep -E '(18.196.196.108|18.195.78.144|18.195.218.6)' | awk '{print $9}' | sort | uniq -c | sort -n | tail -n 5
   4432 200
  • In the last two weeks there have been 47,000 downloads of this same exact PDF by these three IP addresses
  • Apply country and region corrections and deletions on DSpace Test and CGSpace:
$ ./fix-metadata-values.py -i /tmp/2019-02-21-fix-9-countries.csv -db dspace -u dspace -p 'fuuu' -f cg.coverage.country -m 228 -t ACTION -d
$ ./fix-metadata-values.py -i /tmp/2019-02-21-fix-4-regions.csv -db dspace -u dspace -p 'fuuu' -f cg.coverage.region -m 231 -t action -d
$ ./delete-metadata-values.py -i /tmp/2019-02-21-delete-2-countries.csv -db dspace -u dspace -p 'fuuu' -m 228 -f cg.coverage.country -d
$ ./delete-metadata-values.py -i /tmp/2019-02-21-delete-1-region.csv -db dspace -u dspace -p 'fuuu' -m 231 -f cg.coverage.region -d

  • I checked IITA’s 259 Feb 14 records from last month for duplicates using Atmire’s Duplicate Checker on a fresh snapshot of CGSpace on my local machine and everything looks good
  • I am now only waiting to hear from her about where the items should go, though I assume Journal Articles go to IITA Journal Articles collection, etc…
  • Looking at the other half of Udana’s WLE records from 2018-11
    • I finished the ones for Restoring Degraded Landscapes (RDL), but these are for Variability, Risks and Competing Uses (VRC)
    • I did the usual cleanups for whitespace, added regions where they made sense for certain countries, cleaned up the DOI link formats, added rights information based on the publications page for a few items
    • Most worryingly, there are encoding errors in the abstracts for eleven items, for example:
    • 68.15% � 9.45 instead of 68.15% ± 9.45
    • 2003�2013 instead of 2003–2013
  • I think I will need to ask Udana to re-copy and paste the abstracts with more care using Google Docs

  • Linode has alerted a few times since last night that the CPU usage on CGSpace (linode18) was high despite me increasing the alert threshold last week from 250% to 275%—I might need to increase it again!
  • The top IPs before, during, and after this latest alert tonight were:
# zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "01/Feb/2019:(17|18|19|20|21)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10

   1546 5.9.6.51
   2474 45.5.186.2
   5490 85.25.237.71
  • 85.25.237.71 is the “Linguee Bot” that I first saw last month
  • The Solr statistics the past few months have been very high and I was wondering if the web server logs also showed an increase
  • There were just over 3 million accesses in the nginx logs last month:
# time zcat --force /var/log/nginx/* | grep -cE "[0-9]{1,2}/Jan/2019"

  • Linode alerted that CGSpace (linode18) had a higher outbound traffic rate than normal early this morning
  • I don’t see anything interesting in the web server logs around that time though:
# zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "02/Jan/2019:0(1|2|3)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10

  • Switch CGSpace (linode18) to use OpenJDK instead of Oracle JDK
  • I manually installed OpenJDK, then removed Oracle JDK, then re-ran the Ansible playbook to update all configuration files, etc
  • Then I ran all system updates and restarted the server

  • Phil Thornton got an ORCID identifier so we need to add it to the list on CGSpace and tag his existing items
  • I created a GitHub issue to track this #389, because I’m super busy in Nairobi right now

  • New PostgreSQL JDBC driver version 42.2.5
  • I’ll update the DSpace role in our Ansible infrastructure playbooks and run the updated playbooks on CGSpace and DSpace Test
  • Also, I’ll re-run the postgresql tasks because the custom PostgreSQL variables are dynamic according to the system’s RAM, and we never re-ran them after migrating to larger Linodes last month
  • I’m testing the new DSpace 5.8 branch in my Ubuntu 18.04 environment and I’m getting those autowire errors in Tomcat 8.5.30 again:
