Work on preparation of new server for DSpace 7 migration
I’m not quite sure what we need to do for the Handle server
For now I just ran the dspace make-handle-config script and diffed it with the one from DSpace 6
I sent the bundle to the Handle admins to make sure it’s OK before we do the migration
Continue testing and debugging the cgspace-java-helpers on DSpace 7
Work on IFPRI ISNAR archive cleanup

<ul>
<li>I haven’t heard from the Handle admins so I’m preparing a backup solution using nginx streams</li>
<li>This seems to work in my simple tests (this must be outside the <code>http {}</code> block):</li>
</ul>

<li>Here I forwarded a test TCP port 9000 from one server to another and was able to retrieve a test HTML that was running on the target
<ul>
<li>I will have to do TCP and UDP on port 2641, and TCP/HTTP on port 8000.</li>
</ul>
</li>
<li>I did some more minor work on the IFPRI ISNAR archive
<ul>
<li>I got some PDFs from the UMN AgEcon search and fixed some metadata</li>
<li>Then I did some duplicate checking and found five items already on CGSpace</li>

<li>Help Peter proof and upload 252 items from the 2023 Gender conference to CGSpace</li>
<li>Meeting with IFPRI to discuss their migration to CGSpace
<ul>
<li>We agreed to add two new fields, one for IFPRI project and one for IFPRI publication ranking</li>
<li>Most likely we will use <code>cg.identifier.project</code> as a general field and consolidate other project fields there</li>
<li>Not sure which field to use for the publication rank…</li>

<h2 id="2024-01-05">2024-01-05</h2>
<ul>
<li>Proof and upload 51 items in bulk for IFPRI</li>
<li>I did a big cleanup of user groups in anticipation of complaints about slow workflow tasks etc in DSpace 7
<ul>
<li>I removed ILRI editors from all the dozens of CCAFS community and collection groups, and I should do the same for other CRPs since they are closed for two years now</li>

<li>High load on the server and UptimeRobot saying the frontend is flapping
<ul>
<li>I noticed tons of logs from pm2 in the systemd journal, so I disabled those in the systemd unit because they are available from pm2’s log directory anyway</li>
<li>I also noticed the same for Solr, so I disabled stdout for that systemd unit as well</li>
</ul>
</li>
<li>I spent a lot of time bringing back the nginx rate limits we used in DSpace 6 and it seems to have helped</li>

<li>I see that we had 31,744 statistic events yesterday, and 799 have no <code>id</code>!</li>
<li>I asked about this on Slack and will file an issue on GitHub if someone else also finds such records

<li>Several people said they have them, so it’s a bug of some sort in DSpace, not our configuration</li>

<li>Yesterday alone we had 37,000 unique IPs making requests to nginx

</span></span></code></pre></div><ul>
<li>It seems to be a bug in Angular, as this selector comes from Bootstrap 4.6.x and is not invalid
<ul>
<li>But that led me to a more interesting issue with <code>inlineCritical</code> optimization for styles in Angular SSR that might be responsible for causing high load in the frontend</li>
<li>See: <a href="https://github.com/angular/angular/issues/42098">https://github.com/angular/angular/issues/42098</a></li>

<li>Since the production site was flapping a lot I decided to try disabling inlineCriticalCss</li>
<li>There have been on and off load issues with the Angular frontend today

<li>I highly doubt these are home users browsing CGSpace… seems super fishy</li>
<li>Also, over 1,000 IPs from SpaceX Starlink in the last week. RIGHT</li>
