I tried to run the AtomicStatisticsUpdateCLI CUA migration script on DSpace Test (linode26) again and it is still going very slowly and has tons of errors like I noticed yesterday
|
|
|
|
I sent Atmire the dspace.log from today and told them to log into the server to debug the process
|
|
|
|

In other news, I checked the statistics API on DSpace 6 and it’s working

<li>I found a <a href="https://jira.lyrasis.org/browse/DS-4363">bug report on DSpace Jira</a> describing this issue affecting someone else running DSpace 6.3
|
|
<ul>
|
|
<li>They suspect it has to do with the item having some missing group names in its authorization policies</li>
|
|
<li>I added some debugging to <code>dspace-oai/src/main/java/org/dspace/xoai/app/XOAI.java</code> to print the Handle of the item that causes the crash and then I looked at its authorization policies</li>
|
|
<li>Indeed there are some blank group names:</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
<p><img src="/cgspace-notes/2020/06/item-authorizations-dspace63.png" alt="Missing group names in DSpace 6.3 item authorization policy"></p>
|
|
<ul>
|
|
<li>The same item on CGSpace (DSpace 5.8) also has groups with no name:</li>
|
|
</ul>
|
|
<p><img src="/cgspace-notes/2020/06/item-authorizations-dspace58.png" alt="Missing group names in DSpace 5.8 item authorization policy"></p>
|
|
<ul>
|
|
<li>I added some debugging and found exactly where this happens
|
|
<ul>
|
|
<li>As it turns out we can just check if the group policy is null there and it allows the OAI import to proceed</li>
|
|
<li>Aaaaand as it turns out, this was fixed in <code>dspace-6_x</code> in 2018 after DSpace 6.3 was released (see <a href="https://jira.lyrasis.org/browse/DS-4019">DS-4019</a>), so that was a waste of three hours.</li>
|
|
<li>I cherry picked 150e83558103ed7f50e8f323b6407b9cbdf33717 into our current <code>6_x-dev-atmire-modules</code> branch</li>

<ul>
|
|
<li>Maria was asking about some items they are trying to map from the CGIAR Big Data collection into their Alliance of Bioversity and CIAT journal articles collection, but for some reason the items don’t show up in the item mapper
|
|
<ul>
|
|
<li>The items don’t even show up in the XMLUI Discover advanced search, and actually I don’t even see any recent items on the recently submitted part of the collection (but the item pages exist of course)</li>
|
|
<li>Perhaps I need to try a full Discovery re-index:</li>

|
</code></pre><ul>
|
|
<li>Still I don’t see the item in XMLUI search or in the item mapper (and I made sure to clear the Cocoon cache)
|
|
<ul>
|
|
<li>I’m starting to think it’s something related to the database transaction issue…</li>
|
|
<li>I removed our custom JDBC driver from <code>/usr/local/apache-tomcat...</code> so that DSpace will use its own much older one, version 9.1-901-1.jdbc4</li>
|
|
<li>I ran all system updates on the server (linode18) and rebooted it</li>
|
|
<li>After it came back up I had to restart Tomcat five times before all Solr statistics cores came up properly</li>
|
|
<li>Unfortunately this means that the Tomcat JDBC pooling via JNDI doesn’t work, so we’re using only the 30 connections reserved for the DSpace CLI from DSpace’s own internal pool</li>
|
|
<li>Perhaps our previous issues with the database pool from a few years ago will be less now that we have much more aggressive blocking and rate limiting of bots in nginx</li>
|
|
</ul>
|
|
</li>
|
|
<li>I will also import a fresh database snapshot from CGSpace and check if I can map the item in my local environment
|
|
<ul>
|
|
<li>After importing and forcing a full reindex locally I can see the item in search and in the item mapper</li>
|
|
</ul>
|
|
</li>
|
|
<li>Abenet sent another message about two users who are having issues with submission, and I see the number of locks in PostgreSQL has sky rocketed again as of a few days ago:</li>
|
|
</ul>

|
<p><img src="/cgspace-notes/2020/06/postgres_locks_ALL-week.png" alt="PostgreSQL locks week"></p>

|
|
<ul>
|
|
<li>I think I need to just leave this as is with the DSpace default JDBC driver for now, but perhaps I could also downgrade the Tomcat version (I deployed Tomcat 7.0.103 in March, so perhaps that’s relevant)</li>
|
|
<li>Also, I’ll start <em>another</em> full reindexing to see if the issue with mapping is somehow also resolved now that the database connections are working better
|
|
<ul>
|
|
<li>Perhaps related, but this one finished much faster:</li>

<li>In theory we can have different languages for metadata fields but in practice we don’t do that, so we might as well normalize everything to “en_US” (and perhaps I should make a curation task to do this)</li>
|
|
<li>For now I will do it manually on CGSpace and DSpace Test:</li>

</ul>

<li>Note: DSpace Test doesn’t have the <code>resource_type_id</code> column because it’s running DSpace 6 and <a href="https://wiki.lyrasis.org/display/DSPACE/DSpace+Service+based+api">the schema changed to use an object model there</a>
|

<li>Peter asked if it was possible to find all ILRI items that have “zoonoses” or “zoonotic” in their titles and check if they have the ILRI subject “ZOONOTIC DISEASES” (and add it if not)
|

<ul>
|
|
<li>Unfortunately the only way we have currently would be to export the entire ILRI community as a CSV and filter/edit it in OpenRefine</li>

<li>I manually mapped the two Big Data items that Maria had asked about last week by exporting their metadata to CSV and re-importing it
|
|
<ul>
|
|
<li>I still need to look into the underlying issue there, seems to be something in Solr</li>
|
|
<li>Something strang is that, when I search for part of the title in Discovery I get 2,000 results on CGSpace, while on my local DSpace 5.8 environment I get 2!</li>

<ul>
|
|
<li>On DSpace Test, which is currently running DSpace 6, I get 2,000 results but the top one is the correct match and the item does show up in the item mapper
|
|
<ul>
|
|
<li>Interestingly, if I search directly in the Solr <code>search</code> core on CGSpace with a query like <code>handle:10568/108315</code> I don’t see the item, but on my local Solr I see them!</li>
|
|
</ul>
|
|
</li>
|
|
<li>Peter asked if it was easy for me to add ILRI subject “ZOONOTIC DISEASES” to any items in the ILRI community that had “zoonotic” or “zoonoses” in their title, but were missing the ILRI subject
|
|
<ul>
|
|
<li>I exported the ILRI community metadata, cut the three fields I needed, and then filtered and edited the CSV in OpenRefine:</li>
|
|
</ul>
|
|
</li>
|
|
</ul>

<li>Moayad asked why he’s getting HTTP 500 errors on CGSpace

<ul>

<li>I looked in the Nginx logs and I see some HTTP 500 responses, but nothing in nginx’s error.log</li>

<li>So it seems to be related to the database, perhaps that there are less connections in the pool?
|
|
<ul>
|
|
<li>… and on that note, working without the JDBC driver and DSpace’s built-in connection pool since 2020-06-04 hasn’t actually solved anything, the issue with locks and idle in transaction connections is creeping up again!</li>

<li>I think there is some kind of attack going on because I see a bunch of requests for sequential Handles from a similar IP range in a datacenter in Sweden where the user <em>does not</em> re-use their DSpace <code>session_id</code></li>

<li>Looking in the nginx logs I see most (all?) of these requests are using the following user agent:</li>

<li>Looking at the nginx access logs I see that, other than something that seems like Google Feedburner, all hosts using this user agent are all in Sweden!</li>

<li>Skype with Enrico, Moayad, Jane, Peter, and Abenet to see the latest OpenRXV/AReS developments
|
|
<ul>
|
|
<li>One thing Enrico mentioned to me during the call was that they had issues with Altmetric’s user agents, and he said they are apparently using <code>Altmetribot</code> and <code>Postgenomic V2</code></li>
|
|
<li>I looked in our logs and indeed we have those, so I will add them to the nginx rate limit bypass</li>
|
|
<li>I checked the Solr stats and it seems there are only a few thousand in 2016 and a few hundred in other years so I won’t bother adding it to the DSpace robot user agents list</li>
