- 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/10000omgili/0.5 +http://omgili.comIZaBEE/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/patternCyotekWebCopy/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

- Atmire responded asking for more information about the Solr statistics processing bug in CUA so I sent them some full logs
- Also I asked again about the Maven variable interpolation issue for
cua.version.number, and if they would be willing to upgrade CUA to use Font Awesome 5 instead of 4.

- Linode sent an alert that there was high CPU usage on CGSpace (linode18) early this morning
- I looked at the nginx logs using goaccess and I found a few IPs making lots of requests around then:
# cat /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "07/May/2020:(01|03|04)" | goaccess --log-format=COMBINED -
- The two main IPs making requests around then are 188.134.31.88 and 212.34.8.188
- The first is in Russia and it is hitting mostly XMLUI Discover links using dozens of different user agents, a total of 20,000 requests this week
- The second IP is CodeObia testing AReS, a total of 171,000 hits this month
- I will purge both of those IPs from the Solr stats using my
check-spider-ip-hits.sh script:
$ ./check-spider-ip-hits.sh -f /tmp/ips -s statistics -p
Purging 171641 hits from 212.34.8.188 in statistics
Purging 20691 hits from 188.134.31.88 in statistics
Total number of bot hits purged: 192332
- And then I will add 188.134.31.88 to the nginx bad bot list and tell CodeObia to please use a “bot” user agent
- I also changed the nginx config to block requests with blank user agents

- Bizu said she was having issues submitting to CGSpace last week
- The issue sounds like the one Tezira and CTA were having in the last few weeks
- I looked at the PostgreSQL graphs and see there are a lot of connections in “idle in transaction” and “waiting for lock” state:
- I think I’ll downgrade the PostgreSQL JDBC driver from 42.2.12 to 42.2.10, which was the version we were using before these issues started happening
- Atmire sent some feedback about my ongoing issues with their CUA module, but none of it was conclusive yet
- Regarding Font Awesome 5 they will check how much work it will take and give me a quote
- Abenet said some users are questioning why the statistics dropped so much lately, so I made a post to Yammer to explain about the robots
- Last week Peter had asked me to add a new ILRI author’s ORCID iD
- I added it to the controlled vocabulary and tagged the user’s existing ~11 items in CGSpace using this CSV file with my
add-orcid-identifiers-csv.py script:
$ cat 2020-05-11-add-orcids.csv
dc.contributor.author,cg.creator.id
"Lutakome, P.","Pius Lutakome: 0000-0002-0804-2649"
"Lutakome, Pius","Pius Lutakome: 0000-0002-0804-2649"
$ ./add-orcid-identifiers-csv.py -i 2020-05-11-add-orcids.csv -db dspace -u dspace -p 'fuuu' -d
