  • 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:

  • XMLUI fails to load, but the REST, SOLR, JSPUI, etc work
  • The old 5_x-prod-dspace-5.5 branch does work in Ubuntu 18.04 with Tomcat 8.5.30-1ubuntu1.4, however!
  • And the 5_x-prod DSpace 5.8 branch does work in Tomcat 8.5.x on my Arch Linux laptop…
  • I’m not sure where the issue is then!

  • Abenet says she’s getting three emails about periodic statistics reports every day since the DSpace 5.8 upgrade last week
  • They are from the CUA module
  • Two of them have “no data” and one has a “null” title
  • The last one is a report of the top downloaded items, and includes a graph
  • She will try to click the “Unsubscribe” link in the first two to see if it works, otherwise we should contact Atmire
  • The only one she remembers subscribing to is the top downloads one

  • I’m looking over the latest round of IITA records from Sisay: Mercy1806_August_29
    • All fields are split with multiple columns like cg.authorship.types and cg.authorship.types[]
    • This makes it super annoying to do the checks and cleanup, so I will merge them (also time consuming)
    • Five items had dc.date.issued values like 2013-5 so I corrected them to be 2013-05
    • Several metadata fields had values with newlines in them (even in some titles!), which I fixed by trimming the consecutive whitespaces in Open Refine
    • Many (91!) items from before 2011 are indicated as having a CRP, but CRPs didn’t exist then so this is impossible
    • I got all items that were from 2011 and onwards using a custom facet with this GREL on the dc.date.issued column: isNotNull(value.match(/201[1-8].*/)) and then blanking their CRPs
    • Some affiliations with only one separator (|) for multiple values
    • I replaced smart quotes like ’ with plain ones
    • Some inconsistencies in cg.subject.iita like COWPEA and COWPEAS, and YAM and YAMS, etc, as well as some spelling mistakes like IMPACT ASSESSMENTN
    • Some values in the dc.identifier.isbn are actually ISSNs so I moved them to the dc.identifier.issn column
    • I found one invalid ISSN using a custom text facet with the regex from the ISSN page on Wikipedia: isNotBlank(value.match(/^\d{4}-\d{3}[\dxX]$/))
    • One invalid value for dc.type
  • Abenet says she hasn’t received any more subscription emails from the CUA module since she unsubscribed yesterday, so I think we don’t need create an issue on Atmire’s bug tracker anymore

  • Playing with strest to test the DSpace REST API programatically
  • For example, given this test.yaml:
version: 1

requests:
  test:
    method: GET
    url: https://dspacetest.cgiar.org/rest/test
    validate:
      raw: "REST api is running."

  login:
    url: https://dspacetest.cgiar.org/rest/login
    method: POST
    data:
      json: {"email":"test@dspace","password":"thepass"}

  status:
    url: https://dspacetest.cgiar.org/rest/status
    method: GET
    headers:
      rest-dspace-token: Value(login)

  logout:
    url: https://dspacetest.cgiar.org/rest/logout
    method: POST
    headers:
      rest-dspace-token: Value(login)

# vim: set sw=2 ts=2:
  • Works pretty well, though the DSpace logout always returns an HTTP 415 error for some reason
  • We could eventually use this to test sanity of the API for creating collections etc
  • A user is getting an error in her workflow:
2018-09-10 07:26:35,551 ERROR org.dspace.submit.step.CompleteStep @ Caught exception in submission step:

  • Valerio contacted me to point out some issues with metadata on CGSpace, which I corrected in PostgreSQL:
update metadatavalue set text_value='ISI Journal' where resource_type_id=2 and metadata_field_id=226 and text_value='ISI Juornal';
UPDATE 1
update metadatavalue set text_value='ISI Journal' where resource_type_id=2 and metadata_field_id=226 and text_value='ISI journal';
UPDATE 23
update metadatavalue set text_value='ISI Journal' where resource_type_id=2 and metadata_field_id=226 and text_value='YES';
UPDATE 1
delete from metadatavalue where resource_type_id=2 and metadata_field_id=226 and text_value='NO';
DELETE 17
update metadatavalue set text_value='ISI Journal' where resource_type_id=2 and metadata_field_id=226 and text_value='ISI';
UPDATE 15
  • Start working on adding metadata for access and usage rights that we started earlier in 2018 (and also in 2017)
  • The current cg.identifier.status field will become “Access rights” and dc.rights will become “Usage rights”
  • I have some work in progress on the 5_x-rights branch
  • Linode said that CGSpace (linode18) had a high CPU load earlier today
  • When I looked, I see it’s the same Russian IP that I noticed last month:
# zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "10/Sep/2018" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10
   1459 157.55.39.202
   1579 95.108.181.88
   1615 157.55.39.147
   1714 66.249.64.91
   1924 50.116.102.77
   3696 157.55.39.106
   3763 157.55.39.148
   4470 70.32.83.92
   4724 35.237.175.180
  14132 5.9.6.51
  • And this bot is still creating more Tomcat sessions than Nginx requests (WTF?):
# grep -c -E 'session_id=[A-Z0-9]{32}:ip_addr=5.9.6.51' dspace.log.2018-09-10 
14133
  • The user agent is still the same:
Mozilla/5.0 (compatible; MegaIndex.ru/2.0; +http://megaindex.com/crawler)
  • I added .*crawl.* to the Tomcat Session Crawler Manager Valve, so I’m not sure why the bot is creating so many sessions…
  • I just tested that user agent on CGSpace and it does not create a new session:
$ http --print Hh https://cgspace.cgiar.org 'User-Agent:Mozilla/5.0 (compatible; MegaIndex.ru/2.0; +http://megaindex.com/crawler)'

  • I will have to keep an eye on it and perhaps add it to the list of “bad bots” that get rate limited

  • Merge AReS explorer changes to nginx config and deploy on CGSpace so CodeObia can start testing more
  • Re-create my local Docker container for PostgreSQL data, but using a volume for the database data:
$ sudo docker volume create --name dspacetest_data
$ sudo docker run --name dspacedb -v dspacetest_data:/var/lib/postgresql/data -e POSTGRES_PASSWORD=postgres -p 5432:5432 -d postgres:9.6-alpine
  • Sisay is still having problems with the controlled vocabulary for top authors
  • I took a look at the submission template and Firefox complains that the XML file is missing a root element
  • I guess it’s because Firefox is receiving an empty XML file
  • I told Sisay to run the XML file through tidy
  • More testing of the access and usage rights changes

  • Peter was communicating with Altmetric about the OAI mapping issue for item 10568⁄82810 again
  • Altmetric said it was somehow related to the OAI dateStamp not getting updated when the mappings changed, but I said that back in 2018-07 when this happened it was because the OAI was actually just not reflecting all the item’s mappings
  • After forcing a complete re-indexing of OAI the mappings were fine
  • The dateStamp is most probably only updated when the item’s metadata changes, not its mappings, so if Altmetric is relying on that we’re in a tricky spot
  • We need to make sure that our OAI isn’t publicizing stale data… I was going to post something on the dspace-tech mailing list, but never did
  • Linode says that CGSpace (linode18) has had high CPU for the past two hours
  • The top IP addresses today are:
# zcat --force /var/log/nginx/rest.log /var/log/nginx/rest.log.1 | grep -E "13/Sep/2018" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10                                                                                                
     32 46.229.161.131
     38 104.198.9.108
     39 66.249.64.91
     56 157.55.39.224
     57 207.46.13.49
     58 40.77.167.120
     78 169.255.105.46
    702 54.214.112.202
   1840 50.116.102.77
   4469 70.32.83.92
  • And the top two addresses seem to be re-using their Tomcat sessions properly:
$ grep -c -E 'session_id=[A-Z0-9]{32}:ip_addr=70.32.83.92' dspace.log.2018-09-13 | sort | uniq
7
$ grep -c -E 'session_id=[A-Z0-9]{32}:ip_addr=50.116.102.77' dspace.log.2018-09-13 | sort | uniq
2
  • So I’m not sure what’s going on
  • Valerio asked me if there’s a way to get the page views and downloads from CGSpace
  • I said no, but that we might be able to piggyback on the Atmire statlet REST API
  • For example, when you expand the “statlet” at the bottom of an item like 10568⁄97103 you can see the following request in the browser console:
https://cgspace.cgiar.org/rest/statlets?handle=10568/97103&_=1536844046540
  • That JSON file has the total page views and item downloads for the item…
  • Abenet forwarded a request by CIP that item thumbnails be included in RSS feeds
  • I had a quick look at the DSpace 5.x manual and it doesn’t not seem that this is possible (you can only add metadata)
  • Testing the new LDAP server the CGNET says will be replacing the old one, it doesn’t seem that they are using the global catalog on port 3269 anymore, now only 636 is open
  • I did a clean deploy of DSpace 5.8 on Ubuntu 18.04 with some stripped down Tomcat 8 configuration and actually managed to get it up and running without the autowire errors that I had previously experienced
  • I realized that it always works on my local machine with Tomcat 8.5.x, but not when I do the deployment from Ansible in Ubuntu 18.04
  • So there must be something in my Tomcat 8 server.xml template
