CGSpace Notes

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

  • Peter said that CTA is having problems submitting an item to CGSpace
    • Looking at the PostgreSQL stats it seems to be the same issue that Tezira was having last week, as I see the number of connections in ‘idle in transaction’ and ‘waiting for lock’ state are increasing again
    • I see that CGSpace (linode18) is still using PostgreSQL JDBC driver version 42.2.11, and there were some bugs related to transactions fixed in 42.2.12 (which I had updated in the Ansible playbooks, but not deployed yet)

  • Purge a few remaining bots from CGSpace Solr statistics that I had identified a few months ago
    • lua-resty-http/0.10 (Lua) ngx_lua/10000
    • omgili/0.5 +http://omgili.com
    • IZaBEE/IZaBEE-1.01 (Buzzing Abound The Web; https://izabee.com; info at izabee dot com)
    • Twurly v1.1 (https://twurly.org)
    • Pattern/2.6 +http://www.clips.ua.ac.be/pattern
    • CyotekWebCopy/1.7 CyotekHTTP/2.0
  • This is only about 2,500 hits total from the last ten years, and half of these bots no longer seem to exist, so I won’t bother submitting them to the COUNTER-Robots project
  • I noticed that our custom themes were incorrectly linking to the OpenSearch XML file
    • The bug was fixed for Mirage2 in 2015
    • Note that this did not prevent OpenSearch itself from working
    • I will patch this on our DSpace 5.x and 6.x branches
