  • Since yesterday there have been 10,000 REST errors and the site has been unstable again
  • I have blocked access to the API now
  • There are 3,000 IPs accessing the REST API in a 24-hour period!
# awk '{print $1}' /var/log/nginx/rest.log  | uniq | wc -l
3168
  • The two most often requesters are in Ethiopia and Colombia: 213.55.99.121 and 181.118.144.29
  • 100% of the requests coming from Ethiopia are like this and result in an HTTP 500:
GET /rest/handle/10568/NaN?expand=parentCommunityList,metadata HTTP/1.1
  • For now I’ll block just the Ethiopian IP
  • The owner of that application has said that the NaN (not a number) is an error in his code and he’ll fix it

  • Update nginx to 1.10.x branch on CGSpace
  • Fix a reference to dc.type.output in Discovery that I had missed when we migrated to dc.type last month (#223)

Item type in Discovery results

  • DSpace Test is down, catalina.out has lots of messages about heap space from some time yesterday (!)
  • It looks like Sisay was doing some batch imports
  • Hmm, also disk space is full
  • I decided to blow away the solr indexes, since they are 50GB and we don’t really need all the Atmire stuff there right now
  • I will re-generate the Discovery indexes after re-deploying
  • Testing renew-letsencrypt.sh script for nginx
#!/usr/bin/env bash

readonly SERVICE_BIN=/usr/sbin/service
readonly LETSENCRYPT_BIN=/opt/letsencrypt/letsencrypt-auto

# stop nginx so LE can listen on port 443
$SERVICE_BIN nginx stop

$LETSENCRYPT_BIN renew -nvv --standalone --standalone-supported-challenges tls-sni-01 > /var/log/letsencrypt/renew.log 2>&1

LE_RESULT=$?

$SERVICE_BIN nginx start

if [[ "$LE_RESULT" != 0 ]]; then
    echo 'Automated renewal failed:'

    cat /var/log/letsencrypt/renew.log

    exit 1
fi
  • Seems to work well

  • Start looking at more metadata migrations
  • There are lots of fields in dcterms namespace that look interesting, like:
    • dcterms.type
    • dcterms.spatial
  • Not sure what dcterms is…
  • Looks like these were added in DSpace 4 to allow for future work to make DSpace more flexible
  • CGSpace’s dc registry has 96 items, and the default DSpace one has 73.

  • Identify and propose the next phase of CGSpace fields to migrate:

    • dc.title.jtitle → cg.title.journal
    • dc.identifier.status → cg.identifier.status
    • dc.river.basin → cg.river.basin
    • dc.Species → cg.species
    • dc.targetaudience → cg.targetaudience
    • dc.fulltextstatus → cg.fulltextstatus
    • dc.editon → cg.edition
    • dc.isijournal → cg.isijournal

  • Start a test rebase of the 5_x-prod branch on top of the dspace-5.5 tag

  • There were a handful of conflicts that I didn’t understand

  • After completing the rebase I tried to build with the module versions Atmire had indicated as being 5.5 ready but I got this error:

[ERROR] Failed to execute goal on project additions: Could not resolve dependencies for project org.dspace.modules:additions:jar:5.5: Could not find artifact com.atmire:atmire-metadata-quality-api:jar:5.5-2.10.1-0 in sonatype-releases (https://oss.sonatype.org/content/repositories/releases/) -> [Help 1]
  • I’ve sent them a question about it
