I spent a few days working on a Java-based curation task to tag items with ISO 3166-1 Alpha2 country codes based on their cg.coverage.country text values

It looks up the names in ISO 3166-1 first, and then in our CGSpace countries mapping (which has five or so of Peter&rsquo;s preferred &ldquo;display&rdquo; country names)
It implements a &ldquo;force&rdquo; mode too that will clear existing country codes and re-tag everything
It is class based so I can easily add support for other vocabularies, and the technique could even be used for organizations with mappings to ROR and Clarisa&hellip;

<li>I still need to figure out how to integrate this with the DSpace build because currently you have to package it and copy the JAR to the <code>dspace/lib</code> directory (not to mention the config)</li>

<li>I forked the <a href="https://github.com/ilri/dspace-curation-tasks">dspace-curation-tasks to ILRI&rsquo;s GitHub</a> and <a href="https://issues.sonatype.org/browse/OSSRH-59650">submitted the project to Maven Central</a> so I can integrate it more easily with our DSpace build via dependencies</li>

<li>Atmire responded to the ticket about the ongoing upgrade issues
<ul>
<li>They pushed an RC2 version of the CUA module that fixes the FontAwesome issue so that they now use classes instead of Unicode hex characters so our JS + SVG works!</li>
<li>They also said they have never experienced the <code>type: 5</code> site statistics issue, so I need to try to purge those and continue with the stats processing</li>
</ul>
</li>
<li>I purged all unmigrated stats in a few cores and then restarted processing:</li>
</ul>
<pre><code>$ curl -s &quot;http://localhost:8081/solr/statistics/update?softCommit=true&quot; -H &quot;Content-Type: text/xml&quot; --data-binary '&lt;delete&gt;&lt;query&gt;id:/.*unmigrated.*/&lt;/query&gt;&lt;/delete&gt;'

<li>Andrea from Macaroni Bros emailed me a few days ago to say he&rsquo;s having issues with the CGSpace REST API
<ul>
<li>He said he noticed the issues when they were developing the WordPress plugin to harvest CGSpace for the RTB website: <a href="https://www.rtb.cgiar.org/publications/">https://www.rtb.cgiar.org/publications/</a></li>
</ul>
</li>
</ul>
<h2 id="2020-08-04">2020-08-04</h2>
<ul>
<li>Look into the REST API issues that Macaroni Bros raised last week:
<ul>
<li>The first one was about the <code>collections</code> endpoint returning empty items:
<ul>
<li><a href="https://cgspace.cgiar.org/rest/collections/1445/items?limit=1&amp;offset=2">https://cgspace.cgiar.org/rest/collections/1445/items?limit=1&amp;offset=2</a> (offset=2 is correct)</li>
<li><a href="https://cgspace.cgiar.org/rest/collections/1445/items?limit=1&amp;offset=3">https://cgspace.cgiar.org/rest/collections/1445/items?limit=1&amp;offset=3</a> (offset=3 is empty)</li>
<li><a href="https://cgspace.cgiar.org/rest/collections/1445/items?limit=1&amp;offset=4">https://cgspace.cgiar.org/rest/collections/1445/items?limit=1&amp;offset=4</a> (offset=4 is correct again)</li>
</ul>
</li>
<li>I confirm that the second link returns zero items on CGSpace&hellip;
<ul>
<li>I tested on my local development instance and it returns one item correctly&hellip;</li>
<li>I tested on DSpace Test (currently DSpace 6 with UUIDs) and it returns one item correctly&hellip;</li>
<li>Perhaps an indexing issue?</li>
</ul>
</li>
<li>The second issue is the <code>collections</code> endpoint returning the wrong number of items:
<ul>
<li><a href="https://cgspace.cgiar.org/rest/collections/1445">https://cgspace.cgiar.org/rest/collections/1445</a> (numberItems: 63)</li>
<li><a href="https://cgspace.cgiar.org/rest/collections/1445/items">https://cgspace.cgiar.org/rest/collections/1445/items</a> (real number of items: 61)</li>
</ul>
</li>
<li>I confirm that it is indeed happening on CGSpace&hellip;
<ul>
<li>And actually I can replicate the same issue on my local CGSpace 5.8 instance:</li>
</ul>
</li>
</ul>
</li>
</ul>
<pre><code>$ http 'http://localhost:8080/rest/collections/1445' | json_pp | grep numberItems
   &quot;numberItems&quot; : 63,
$ http 'http://localhost:8080/rest/collections/1445/items' jq '. | length'
61
</code></pre><ul>
<li>Also on DSpace Test (which is running DSpace 6!), though the issue is slightly different there:</li>
</ul>
<pre><code>$ http 'https://dspacetest.cgiar.org/rest/collections/5471c3aa-202e-42f0-96c2-497a18e3b708' | json_pp | grep numberItems
   &quot;numberItems&quot; : 61,
$ http 'https://dspacetest.cgiar.org/rest/collections/5471c3aa-202e-42f0-96c2-497a18e3b708/items' | jq '. | length'
59
</code></pre><ul>
<li>Ah! I exported that collection&rsquo;s metadata and checked it in OpenRefine, where I noticed that two items are mapped twice
<ul>
<li>I dealt with this problem in 2017-01 and the solution is to check the <code>collection2item</code> table:</li>
</ul>
</li>
</ul>
<pre><code>dspace=# SELECT * FROM collection2item WHERE item_id = '107687';
   id   | collection_id | item_id
--------+---------------+---------
 133698 |           966 |  107687
 134685 |          1445 |  107687
 134686 |          1445 |  107687
(3 rows)
</code></pre><ul>
<li>So for each id you can delete one duplicate mapping:</li>
</ul>
<pre><code>dspace=# DELETE FROM collection2item WHERE id='134686';
dspace=# DELETE FROM collection2item WHERE id='128819';
</code></pre><ul>
<li>Update countries on CGSpace to be closer to ISO 3166-1 with some minor differences based on Peter&rsquo;s preferred display names</li>
</ul>
<pre><code>$ cat 2020-08-04-PB-new-countries.csv
cg.coverage.country,correct
CAPE VERDE,CABO VERDE
COCOS ISLANDS,COCOS (KEELING) ISLANDS
&quot;CONGO, DR&quot;,&quot;CONGO, DEMOCRATIC REPUBLIC OF&quot;

<li>I had to restart Tomcat 7 three times before all the Solr statistics cores came up properly
<ul>
<li>I started a full Discovery re-indexing</li>
</ul>
</li>
</ul>
<h2 id="2020-08-05">2020-08-05</h2>
<ul>
<li>Port my <a href="https://github.com/ilri/dspace-curation-tasks">dspace-curation-tasks</a> to DSpace 6 and tag version <code>6.0-SNAPSHOT</code></li>
<li>I downloaded the <a href="https://unstats.un.org/unsd/methodology/m49/overview/">UN M.49</a> CSV file to start working on updating the CGSpace regions
<ul>
<li>First issue is they don&rsquo;t version the file so you have no idea when it was released</li>
<li>Second issue is that three rows have errors due to not using quotes around &ldquo;China, Macao Special Administrative Region&rdquo;</li>
</ul>
</li>
<li>Bizu said she was having problems approving tasks on CGSpace
<ul>
<li>I looked at the PostgreSQL locks and they have skyrocketed since yesterday:</li>
</ul>
</li>
</ul>
<p><img src="/cgspace-notes/2020/08/postgres_locks_ALL-day.png" alt="PostgreSQL locks day"></p>
<p><img src="/cgspace-notes/2020/08/postgres_querylength_ALL-day.png" alt="PostgreSQL query length day"></p>
<ul>
<li>Seems that something happened yesterday afternoon at around 5PM&hellip;
<ul>
<li>For now I will just run all updates on the server and reboot it, as I have no idea what causes this issue</li>
<li>I had to restart Tomcat 7 three times after the server came back up before all Solr statistics cores came up properly</li>
</ul>
</li>
<li>I checked the nginx logs around 5PM yesterday to see who was accessing the server:</li>
</ul>
<pre><code># cat /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E '04/Aug/2020:(17|18)' | goaccess --log-format=COMBINED -
</code></pre><ul>
<li>I see the Macaroni Bros are using their new user agent for harvesting: <code>RTB website BOT</code>
<ul>
<li>But that pattern doesn&rsquo;t match in the nginx bot list or Tomcat&rsquo;s crawler session manager valve because we&rsquo;re only checking for <code>[Bb]ot</code>!</li>
<li>So they have created thousands of Tomcat sessions:</li>
</ul>
</li>
</ul>
<pre><code>$ cat dspace.log.2020-08-04 | grep -E &quot;(63.32.242.35|64.62.202.71)&quot; | grep -E 'session_id=[A-Z0-9]{32}' | sort | uniq | wc -l
5693
</code></pre><ul>
<li>DSpace itself uses a case-sensitive regex for user agents so there are no hits from those IPs in Solr, but I need to tweak the other regexes so they don&rsquo;t misuse the resources
<ul>
<li>Perhaps <code>[Bb][Oo][Tt]</code>&hellip;</li>
</ul>
</li>
<li>I see another IP 104.198.96.245, which is also using the &ldquo;RTB website BOT&rdquo; but there are 70,000 hits in Solr from earlier this year before they started using the user agent
<ul>
<li>I purged all the hits from Solr, including a few thousand from 64.62.202.71</li>
</ul>
</li>
<li>A few more IPs causing lots of Tomcat sessions yesterday:</li>
</ul>
<pre><code>$ cat dspace.log.2020-08-04 | grep &quot;38.128.66.10&quot; | grep -E 'session_id=[A-Z0-9]{32}' | sort | uniq | wc -l
1585
$ cat dspace.log.2020-08-04 | grep &quot;64.62.202.71&quot; | grep -E 'session_id=[A-Z0-9]{32}' | sort | uniq | wc -l
5691
</code></pre><ul>
<li>38.128.66.10 isn&rsquo;t creating any Solr statistics due to our DSpace agents pattern, but they are creating lots of sessions so perhaps I need to force them to use one session in Tomcat:</li>
</ul>
<pre><code>Mozilla/5.0 (Windows NT 5.1) brokenlinkcheck.com/1.2
</code></pre><ul>
<li>64.62.202.71 is using a user agent I&rsquo;ve never seen before:</li>
</ul>
<pre><code>Mozilla/5.0 (compatible; +centuryb.o.t9[at]gmail.com)
</code></pre><ul>
<li>So now our &ldquo;bot&rdquo; regex can&rsquo;t even match that&hellip;
<ul>
<li>Unless we change it to <code>[Bb]\.?[Oo]\.?[Tt]\.?</code>&hellip; which seems to match all variations of &ldquo;bot&rdquo; I can think of right now, according to <a href="https://regexr.com/59lpt">regexr.com</a>:</li>
</ul>
</li>
</ul>
<pre><code>RTB website BOT

<li>And another IP belonging to Turnitin (the alternate user agent of Turnitinbot):</li>

<pre><code>$ cat dspace.log.2020-08-04 | grep &quot;199.47.87.145&quot; | grep -E 'sessi

<h2 id="2020-08-06">2020-08-06</h2>
<ul>
<li>I have been working on processing the Solr statistics with the Atmire tool on DSpace Test the last few days:
<ul>
<li>statistics:
<ul>
<li>2,040,385 docs: 2h 28m 49s</li>
</ul>
</li>
<li>statistics-2019:
<ul>
<li>8,960,000 docs: 12h 7s</li>
<li>1,780,575 docs: 2h 7m 29s</li>
</ul>
</li>
<li>statistics-2018:
<ul>
<li>1,970,000 docs: 12h 1m 28s</li>
<li>360,000 docs: 2h 54m 56s (Linode rebooted)</li>
<li>1,110,000 docs: 7h 1m 44s (Restarted Tomcat, oops)</li>
</ul>
</li>
</ul>
</li>
<li>I decided to start the 2018 core over again, so I re-synced it from CGSpace and started again from the solr-upgrade-statistics-6x tool and now I&rsquo;m having the same issues with Java heap space that I had last month
<ul>
<li>The process kept crashing due to memory, so I increased the memory to 3072m and finally 4096m&hellip;</li>
<li>Also, I decided to try to purge all the <code>-unmigrated</code> docs that it had found so far to see if that helps&hellip;</li>
<li>There were about 466,000 records unmigrated so far, most of which were <code>type: 5</code> (SITE statistics)</li>
<li>Now it is processing again&hellip;</li>
</ul>
</li>
<li>I developed a small Java class called <code>FixJpgJpgThumbnails</code> to remove &ldquo;.jpg.jpg&rdquo; thumbnails from the <code>THUMBNAIL</code> bundle and replace them with their originals from the <code>ORIGINAL</code> bundle
<ul>
<li>The code is based on <a href="https://github.com/UoW-IRRs/DSpace-Scripts/blob/master/src/main/java/nz/ac/waikato/its/irr/scripts/RemovePNGThumbnailsForPDFs.java">RemovePNGThumbnailsForPDFs.java</a> by Andrea Schweer</li>
<li>I incorporated it into my dspace-curation-tasks repository, then renamed it to <a href="https://github.com/ilri/cgspace-java-helpers">cgspace-java-helpers</a></li>
<li>In testing I found that I can replace ~4,000 thumbnails on CGSpace!</li>
</ul>
</li>
</ul>
<h2 id="2020-08-07">2020-08-07</h2>
<ul>
<li>I improved the <code>RemovePNGThumbnailsForPDFs.java</code> a bit more to exclude infographics and original bitstreams larger than 100KiB
<ul>
<li>I ran it on CGSpace and it cleaned up 3,769 thumbnails!</li>
<li>Afterwards I ran <code>dspace cleanup -v</code> to remove the deleted thumbnails</li>
</ul>
</li>
</ul>
<h2 id="2020-08-08">2020-08-08</h2>
<ul>
<li>The Atmire stats processing for the statistics-2018 Solr core keeps stopping with this error:</li>

<li>The group members are the same so I went through and replaced the <code>CCAFS approvers1</code> group everywhere manually&hellip;</li>
<li>I also removed some old CCAFS users from the groups</li>
</ul>

<ul>
<li>I ran the CountryCodeTagger on CGSpace and it was very fast:</li>
</ul>
<pre><code>$ time chrt -b 0 dspace curate -t countrycodetagger -i all -r - -l 500 -s object | tee /tmp/2020-08-27-countrycodetagger.log
real    2m7.643s
user    1m48.740s
sys     0m14.518s
$ grep -c added /tmp/2020-08-27-countrycodetagger.log
46
</code></pre><ul>
<li>I still haven&rsquo;t created a cron job for it&hellip; but it&rsquo;s good to know that when it doesn&rsquo;t need to add very many country codes that it is very fast (original run a few weeks ago added 50,000 country codes)
<ul>
<li>I wonder how DSpace 6 will perform when it doesn&rsquo;t need to add all the codes, like after the initial run</li>
</ul>
</li>
</ul>
