Notes

2022-09-01

  • A bit of work on the "Mapping CG Core–CGSpace–MEL–MARLO Types" spreadsheet
  • I tested an item submission on DSpace Test with the Cocoon org.apache.cocoon.uploads.autosave=false change
    • The submission works as expected
  • Start debugging some region-related issues with csv-metadata-quality
    • I created a new test file test-geography.csv with some different scenarios
    • I also fixed a few bugs and improved the region-matching logic

2022-09-02

  • I worked a bit more on exclusion and skipping logic in csv-metadata-quality
    • I also pruned and updated all the Python dependencies
    • Then I released version 0.6.0 now that the excludes and region matching support is working way better

  • Started a harvest on AReS last night
  • Looking over the Solr statistics from last month I see many user agents that look suspicious:
    • Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.2; WOW64; Trident/7.0; .NET4.0E; .NET4.0C)

    • WebAPIClient

    • Mozilla/5.0 (compatible; woorankreview/2.0; +https://www.woorank.com/)
  • For example, some are apparently using versions of Firefox that are over ten years old, and some are obviously trying to look like valid user agents, but making typos (Mozilla / 5.0)
  • Tons of hosts making requests likt this:
GET /bitstream/handle/10568/109408/Milk%20testing%20lab%20protocol.pdf?sequence=1&isAllowed=\x22><script%20>alert(String.fromCharCode(88,83,83))</script> HTTP/1.1" 400 5 "-" "Mozilla/5.0 (Windows NT 10.0; WOW64; Rv:50.0) Gecko/20100101 Firefox/50.0
  • I got a list of hosts making requests like that so I can purge their hits:
# zcat /var/log/nginx/{access,library-access,oai,rest}.log.[123]*.gz | grep 'String.fromCharCode(' | awk '{print $1}' | sort -u > /tmp/ips.txt 

$ awk '{print $1}' /tmp/hetzner.txt | wc -l
36
$ sort -u /tmp/hetzner-combined.txt  | wc -l
49
  • I will add this new list to nginx's bot-networks.conf so they get throttled on scraping XMLUI and get classified as bots in Solr statistics
  • Then I purged hits from the following user agents:
$ ./ilri/check-spider-hits.sh -f /tmp/agents
Found 374 hits from curb in statistics
Found 350 hits from bitdiscovery in statistics
Found 564 hits from omgili in statistics
Found 390 hits from Vizzit in statistics
Found 9125 hits from AdobeUxTechC4-Async in statistics
Found 97 hits from ZaloPC-win32-24v473 in statistics
Found 518 hits from nbertaupete95 in statistics
Found 218 hits from Scoop.it in statistics
Found 584 hits from WebAPIClient in statistics

Total number of hits from bots: 12220
  • Then I will add these user agents to the ILRI spider override in DSpace

  • I'm testing dspace-statistics-api with our DSpace 7 test server
    • After setting up the env and the database the python -m dspace_statistics_api.indexer runs without issues
    • While playing with Solr I tried to search for statistics from this month using time:2022-09* but I get this error: "Can't run prefix queries on numeric fields"
    • I guess that the syntax in Solr changed since 4.10...
    • This works, but is super annoying: time:[2022-09-01T00:00:00Z TO 2022-09-30T23:59:59Z]

2022-09-07

  • I tested the controlled-vocabulary changes on DSpace 6 and they work fine
    • Last week I found that DSpace 7 is more strict with controlled vocabularies and requires IDs for all node values
    • This is a pain because it means I have to re-do the IDs in each file every time I update them
    • If I add id="0000" to each, then I can use this vim expression let i=0001 | g/0000/s//\=i/ | let i=i+1 to replace the numbers with increments starting from 1
  • Meeting with Marie Angelique, Abenet, Sarа, аnd Margarita to continue the discussion about Types from last week
    • We made progress with concrete actions and will continue next week

2022-09-08

  • I had a meeting with Nicky from UNEP to discuss issues they are having with their DSpace
    • I told her about the meeting of DSpace community people that we're planning at ILRI in the next few weeks

2022-09-09

  • Add some value mappings to AReS because I see a lot of incorrect regions and countries
  • I also found some values that were blank in CGSpace so I deleted them:
dspace=# BEGIN;
BEGIN
dspace=# DELETE FROM metadatavalue WHERE dspace_object_id IN (SELECT uuid FROM item) AND text_value='';
DELETE 70
dspace=# COMMIT;
COMMIT
  • Start a full Discovery index on CGSpace to catch these changes in the Discovery
