Help CCAFS with regenerating some item thumbnails after they uploaded new PDFs to some items on CGSpace
A user on the dspace-tech mailing list offered some suggestions for troubleshooting the problem with the inability to delete certain items
Apparently if the item is in the workflowitem table it is submitted to a workflow
And if it is in the workspaceitem table it is in the pre-submitted state
The item seems to be in a pre-submitted state, so I tried to delete it from there:
dspace=# DELETE FROM workspaceitem WHERE item_id=74648;
DELETE 1
But after this I tried to delete the item from the XMLUI and it is still present&hellip;

<ul>
<li>Help CCAFS with regenerating some item thumbnails after they uploaded new PDFs to some items on CGSpace</li>
<li>A user on the dspace-tech mailing list offered some suggestions for troubleshooting the problem with the inability to delete certain items
<ul>
<li>Apparently if the item is in the <code>workflowitem</code> table it is submitted to a workflow</li>
<li>And if it is in the <code>workspaceitem</code> table it is in the pre-submitted state</li>
</ul>
</li>
<li>The item seems to be in a pre-submitted state, so I tried to delete it from there:</li>
</ul>
<pre><code>dspace=# DELETE FROM workspaceitem WHERE item_id=74648;
DELETE 1
</code></pre><ul>
<li>But after this I tried to delete the item from the XMLUI and it is <em>still</em> present&hellip;</li>
</ul>
<ul>
<li>I managed to delete the problematic item from the database
<ul>
<li>First I deleted the item&rsquo;s bitstream in XMLUI and then ran <code>dspace cleanup -v</code> to remove it from the assetstore</li>
<li>Then I ran the following SQL:</li>
</ul>
</li>
</ul>
<pre><code>dspace=# DELETE FROM metadatavalue WHERE resource_id=74648;
dspace=# DELETE FROM workspaceitem WHERE item_id=74648;
dspace=# DELETE FROM item WHERE item_id=74648;
</code></pre><ul>
<li>Now the item is (hopefully) really gone and I can continue to troubleshoot the issue with REST API&rsquo;s <code>/items/find-by-metadata-value</code> endpoint
<ul>
<li>Of course I run into another HTTP 401 error when I continue trying the LandPortal search from last month:</li>
</ul>
</li>
</ul>
<pre><code>$ curl -f -H &quot;Content-Type: application/json&quot; -X POST &quot;http://localhost:8080/rest/items/find-by-metadata-field&quot; -d '{&quot;key&quot;:&quot;cg.subject.cpwf&quot;, &quot;value&quot;:&quot;WATER MANAGEMENT&quot;,&quot;language&quot;: &quot;en_US&quot;}'
curl: (22) The requested URL returned error: 401 Unauthorized
</code></pre><ul>
<li>The DSpace log shows the item ID (because I modified the error text):</li>
</ul>
<pre><code>2019-05-01 11:41:11,069 ERROR org.dspace.rest.ItemsResource @ User(anonymous) has not permission to read item(id=77708)!
</code></pre><ul>
<li>If I delete that one I get another, making the list of item IDs so far:
<ul>
<li>74648</li>
<li>77708</li>
<li>85079</li>
</ul>
</li>
<li>Some are in the <code>workspaceitem</code> table (pre-submission), others are in the <code>workflowitem</code> table (submitted), and others are actually approved, but withdrawn&hellip;
<ul>
<li>This is actually a worthless exercise because the real issue is that the <code>/items/find-by-metadata-value</code> endpoint is simply designed flawed and shouldn&rsquo;t be fatally erroring when the search returns items the user doesn&rsquo;t have permission to access</li>
<li>It would take way too much time to try to fix the fucked up items that are in limbo by deleting them in SQL, but also, it doesn&rsquo;t actually fix the problem because some items are <em>submitted</em> but <em>withdrawn</em>, so they actually have handles and everything</li>
<li>I think the solution is to recommend people don&rsquo;t use the <code>/items/find-by-metadata-value</code> endpoint</li>
</ul>
</li>
<li>CIP is asking about embedding PDF thumbnail images in their RSS feeds again
<ul>
<li>They asked in 2018-09 as well and I told them it wasn&rsquo;t possible</li>
<li>To make sure, I looked at <a href="https://wiki.lyrasis.org/display/DSPACE/Enable+Media+RSS+Feeds">the documentation for RSS media feeds</a> and tried it, but couldn&rsquo;t get it to work</li>
<li>It seems to be geared towards iTunes and Podcasts&hellip; I dunno</li>
</ul>
</li>
<li>CIP also asked for a way to get an XML file of all their RTB journal articles on CGSpace
<ul>
<li>I told them to use the REST API like (where <code>1179</code> is the id of the RTB journal articles collection):</li>
</ul>
</li>
</ul>
<pre><code>https://cgspace.cgiar.org/rest/collections/1179/items?limit=812&amp;expand=metadata

<li>A user from CIAT emailed to say that CGSpace submission emails have not been working the last few weeks
<ul>
<li>I checked the <code>dspace test-email</code> script on CGSpace and they are indeed failing:</li>

</li>
</ul>
<pre><code>$ dspace test-email

<li>Peter pointed out that Solr stats are only showing 2019 stats
<ul>
<li>I looked at the Solr Admin UI and I see:</li>
</ul>
</li>
</ul>
<pre><code>statistics-2018: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error opening new searcher
</code></pre><ul>
<li>As well as this error in the logs:</li>
</ul>
<pre><code>Caused by: org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out: NativeFSLock@/home/cgspace.cgiar.org/solr/statistics-2018/data/index/write.lock
</code></pre><ul>
<li>Strangely enough, I <em>do</em> see the statistics-2018, statistics-2017, etc cores in the Admin UI&hellip;</li>
<li>I restarted Tomcat a few times (and even deleted all the Solr write locks) and at least five times there were issues loading one statistics core, causing the Atmire stats to be incomplete
<ul>
<li>Also, I tried to increase the <code>writeLockTimeout</code> in <code>solrconfig.xml</code> from the default of 1000ms to 10000ms</li>
<li>Eventually the Atmire stats started working, despite errors about &ldquo;Error opening new searcher&rdquo; in the Solr Admin UI</li>
<li>I wrote to the dspace-tech mailing list again on the thread from March, 2019</li>
</ul>
</li>
<li>There were a few alerts from UptimeRobot about CGSpace going up and down this morning, along with an alert from Linode about 596% load
<ul>
<li>Looking at the Munin stats I see an exponential rise in DSpace XMLUI sessions, firewall activity, and PostgreSQL connections this morning:</li>

<li>I finally had time to analyze the 7,000 IPs from the major traffic spike on 2019-05-06 after several runs of my <code>resolve-addresses.py</code> script (ipapi.co has a limit of 1,000 requests per day)</li>
<li>Resolving the unique IP addresses to organization and AS names reveals some pretty big abusers:
<ul>
<li>1213 from Region40 LLC (AS200557)</li>
<li>697 from Trusov Ilya Igorevych (AS50896)</li>
<li>687 from UGB Hosting OU (AS206485)</li>
<li>620 from UAB Rakrejus (AS62282)</li>
<li>491 from Dedipath (AS35913)</li>
<li>476 from Global Layer B.V. (AS49453)</li>
<li>333 from QuadraNet Enterprises LLC (AS8100)</li>

<li>125 from Blockchain Network Solutions Ltd (AS43444)</li>
<li>118 from Silverstar Invest Limited (AS35624)</li>
</ul>

<li>All of the IPs from these networks are using generic user agents like this, but MANY more, and they change many times:</li>

<li>I found a <a href="https://www.qurium.org/alerts/azerbaijan/azerbaijan-and-the-region40-ddos-service/">blog post from 2018 detailing an attack from a DDoS service</a> that matches our pattern exactly</li>
