@ -228,4 +228,25 @@ java.lang.NullPointerException: Cannot invoke "org.dspace.discovery.configuratio
- Now I need to figure out what it is about those five that causes them to not work!
- Ah, after debugging with someone on the DSpace Slack, I realized that DSpace expects these vocabularies to have corresponding indexes configured in `discovery.xml`, and they must be added as search filters AND sidebar facets.
## 2023-06-29
- I noticed there is now a [patched version of the Handle JAR for DSpace 6.x](https://github.com/DSpace/DSpace/issues/8557#issuecomment-1595340249)
- This fixes the [issue in OpenJDK 1.8.0_352](https://groups.google.com/g/dspace-tech/c/PqjfA5mqG4w/m/FhxI5oXhFwAJ?pli=1), so we can remove the apt pin on JDK now
- I deployed it on CGSpace and it's working!
- I lowercased all our AGROVOC terms because I noticed a few that were not:
```console
dspace=# BEGIN;
BEGIN
dspace=*# UPDATE metadatavalue SET text_value=LOWER(text_value) WHERE dspace_object_id IN (SELECT uuid FROM item) AND metadata_field_id=187 AND text_value ~ '[[:upper:]]';
UPDATE 53
dspace=*# COMMIT;
```
- After more discussion about the NullPointerException related to browse options, I filed [an issue](https://github.com/DSpace/DSpace/issues/8927)
## 2023-06-30
- I added another custom component to display CGIAR Impact Area icons in the DSpace 7 test

+++
Proposed changes to the CG Core controlled vocabulary for output types after review of actual usage by several CGIAR open access repositories.
With reference to [CG Core v2 draft standard](https://agriculturalsemantics.github.io/cg-core/cgcore.html) by Marie-Angélique as well as [DCMI DCTERMS](http://www.dublincore.org/specifications/dublin-core/dcmi-terms/).

- [Proposed Changes](#proposed-changes)
- [Out of Scope](#out-of-scope)
- [Implementation Progress](#implementation-progress)
## Proposed Changes
As of 2021-01-18 the scope of the changes includes the following fields:
- cg.creator.id→cg.creator.identifier
- ORCID identifiers
- dc.format.extent→dcterms.extent
- dc.date.issued→dcterms.issued
- dc.description.abstract→dcterms.abstract
- dc.description→dcterms.description
- dc.description.sponsorship→cg.contributor.donor
- values from CrossRef or Grid.ac if possible
- dc.description.version→cg.reviewStatus
- cg.fulltextstatus→cg.howPublished
- CGSpace uses values like "Formally Published" or "Grey Literature"
- dc.identifier.citation→dcterms.bibliographicCitation
- cg.identifier.status→dcterms.accessRights
- current values are "Open Access" and "Limited Access"
- future values are possibly "Open" and "Restricted"?
- dc.language.iso→dcterms.language
- current values are ISO 639-1 (aka Alpha 2)
- future values are possibly ISO 639-3 (aka Alpha 3)?
- cg.link.reference→dcterms.relation
- dc.publisher→dcterms.publisher
- dc.relation.ispartofseries will be split into:
- series name: dcterms.isPartOf
- series number: cg.number
- dc.rights→dcterms.license
- Using [SPDX license identifiers](https://spdx.org/licenses/) if possible
- dc.source→cg.journal
- dc.subject→dcterms.subject
- dc.type→dcterms.type
- dc.identifier.isbn→cg.isbn
- dc.identifier.issn→cg.issn
- cg.targetaudience→dcterms.audience
### Out of Scope
The following fields are currently out of the scope of this migration because they are used internally by DSpace 5.x/6.x and would be difficult to change without significant modifications to the core of the code:
- dc.title (`IncludePageMeta.java` only considers DC when building pageMeta, which we rely on in XMLUI because of XSLT from DRI)
- dc.title.alternative
- dc.date.available
- dc.date.accessioned
- dc.identifier.uri (hard coded for Handle assignment upon item submission)
- dc.description.provenance
- dc.contributor.author (`IncludePageMeta.java` only considers DC when building pageMeta, which we rely on in XMLUI because of XSLT from DRI)

<li>For now I have increased the limit from 60 to 90, run updates, and rebooted the server</li>
</ul>
<h2 id="2015-11-24">2015-11-24</h2>
<ul>
<li>CGSpace went down again</li>
<li>Getting emails from uptimeRobot and uptimeButler that it&rsquo;s down, and Google Webmaster Tools is sending emails that there is an increase in crawl errors</li>
<li>Looks like there are still a bunch of idle PostgreSQL connections:</li>
</ul>
<pre tabindex="0"><code>$ psql -c &#39;SELECT * from pg_stat_activity;&#39; | grep idle | grep -c cgspace

<li>For some reason the number of idle connections is very high since we upgraded to DSpace 5</li>
</ul>
<h2 id="2015-11-25">2015-11-25</h2>
<ul>
<li>Troubleshoot the DSpace 5 OAI breakage caused by nginx routing config</li>
<li>The OAI application requests stylesheets and javascript files with the path <code>/oai/static/css</code>, which gets matched here:</li>
</ul>
<pre tabindex="0"><code># static assets we can load from the file system directly with nginx
location ~ /(themes|static|aspects/ReportingSuite) {
try_files $uri @tomcat;
...
</code></pre><ul>
<li>The document root is relative to the xmlui app, so this gets a 404—I&rsquo;m not sure why it doesn&rsquo;t pass to <code>@tomcat</code></li>
<li>Anyways, I can&rsquo;t find any URIs with path <code>/static</code>, and the more important point is to handle all the static theme assets, so we can just remove <code>static</code> from the regex for now (who cares if we can&rsquo;t use nginx to send Etags for OAI CSS!)</li>
<li>Also, I noticed we aren&rsquo;t setting CSP headers on the static assets, because in nginx headers are inherited in child blocks, but if you use <code>add_header</code> in a child block it doesn&rsquo;t inherit the others</li>
<li>We simply need to add <code>include extra-security.conf;</code> to the above location block (but research and test first)</li>
<li>We should add WOFF assets to the list of things to set expires for:</li>
</ul>
<pre tabindex="0"><code>location ~* \.(?:ico|css|js|gif|jpe?g|png|woff)$ {
</code></pre><ul>
<li>We should also add <code>aspects/Statistics</code> to the location block for static assets (minus <code>static</code> from above):</li>
</ul>
<pre tabindex="0"><code>location ~ /(themes|aspects/ReportingSuite|aspects/Statistics) {
</code></pre><ul>
<li>Need to check <code>/about</code> on CGSpace, as it&rsquo;s blank on my local test server and we might need to add something there</li>
<li>CGSpace has been up and down all day due to PostgreSQL idle connections (current DSpace pool is 90):</li>
</ul>
<pre tabindex="0"><code>$ psql -c &#39;SELECT * from pg_stat_activity;&#39; | grep idle | grep -c cgspace
93
</code></pre><ul>
<li>I looked closer at the idle connections and saw that many have been idle for hours (current time on server is <code>2015-11-25T20:20:42+0000</code>):</li>

<li>It seems there is some sense changing DSpace&rsquo;s default <code>db.maxidle</code> from unlimited (-1) to something like 8 (Tomcat default) or 10 (Confluence default)</li>
<li>Change <code>db.maxidle</code> from -1 to 10, reduce <code>db.maxconnections</code> from 90 to 50, and restart postgres and tomcat7</li>
<li>Also redeploy DSpace Test with a clean sync of CGSpace and mirror these database settings there as well</li>
<li>Also deploy the nginx fixes for the <code>try_files</code> location block as well as the expires block</li>
</ul>
<h2 id="2015-11-26">2015-11-26</h2>
<ul>
<li>CGSpace behaving much better since changing <code>db.maxidle</code> yesterday, but still two up/down notices from monitoring this morning (better than 50!)</li>
<li>CCAFS colleagues mentioned that the REST API is very slow, 24 seconds for one item</li>
<li>Not as bad for me, but still unsustainable if you have to get many:</li>
</ul>

<li>Monitoring e-mailed in the evening to say CGSpace was down</li>
<li>Idle connections in PostgreSQL again:</li>
</ul>
<pre tabindex="0"><code>$ psql -c &#39;SELECT * from pg_stat_activity;&#39; | grep cgspace | grep -c idle
66
</code></pre><ul>
<li>At the time, the current DSpace pool size was 50&hellip;</li>
<li>I reduced the pool back to the default of 30, and reduced the <code>db.maxidle</code> settings from 10 to 8</li>
</ul>
<h2 id="2015-11-29">2015-11-29</h2>
<ul>
<li>Still more alerts that CGSpace has been up and down all day</li>
<li>Current database settings for DSpace:</li>
</ul>
<pre tabindex="0"><code>db.maxconnections = 30
db.maxwait = 5000
db.maxidle = 8
db.statementpool = true
</code></pre><ul>
<li>And idle connections:</li>
</ul>
<pre tabindex="0"><code>$ psql -c &#39;SELECT * from pg_stat_activity;&#39; | grep cgspace | grep -c idle
49
</code></pre><ul>
<li>Perhaps I need to start drastically increasing the connection limits—like to 300—to see if DSpace&rsquo;s thirst can ever be quenched</li>
<li>On another note, SUNScholar&rsquo;s notes suggest adjusting some other postgres variables: <a href="http://wiki.lib.sun.ac.za/index.php/SUNScholar/Optimisations/Database">http://wiki.lib.sun.ac.za/index.php/SUNScholar/Optimisations/Database</a></li>
<li>This might help with REST API speed (which I mentioned above and still need to do real tests)</li>

<li>Current database settings for DSpace are <code>db.maxconnections = 30</code> and <code>db.maxidle = 8</code>, yet idle connections are exceeding this:</li>
</ul>
<pre tabindex="0"><code>$ psql -c &#39;SELECT * from pg_stat_activity;&#39; | grep cgspace | grep -c idle
39
</code></pre><ul>
<li>I restarted PostgreSQL and Tomcat and it&rsquo;s back</li>
<li>On a related note of why CGSpace is so slow, I decided to finally try the <code>pgtune</code> script to tune the postgres settings:</li>
</ul>
<pre tabindex="0"><code># apt-get install pgtune
# pgtune -i /etc/postgresql/9.3/main/postgresql.conf -o postgresql.conf-pgtune
# mv /etc/postgresql/9.3/main/postgresql.conf /etc/postgresql/9.3/main/postgresql.conf.orig
# mv postgresql.conf-pgtune /etc/postgresql/9.3/main/postgresql.conf
</code></pre><ul>
<li>It introduced the following new settings:</li>
</ul>
<pre tabindex="0"><code>default_statistics_target = 50
maintenance_work_mem = 480MB
constraint_exclusion = on
checkpoint_completion_target = 0.9
effective_cache_size = 5632MB
work_mem = 48MB
wal_buffers = 8MB
checkpoint_segments = 16
shared_buffers = 1920MB
max_connections = 80
</code></pre><ul>
<li>Now I need to go read PostgreSQL docs about these options, and watch memory settings in munin etc</li>
<li>For what it&rsquo;s worth, now the REST API should be faster (because of these PostgreSQL tweaks):</li>

<li>We weren&rsquo;t out of heap yet, but it&rsquo;s probably fair enough that the DSpace 5 upgrade (and new Atmire modules) requires more memory so it&rsquo;s ok</li>

<h2 id="2016-01-14">2016-01-14</h2>
<ul>
<li>Update CCAFS project identifiers in input-forms.xml</li>
<li>Run system updates and restart the server</li>
</ul>
<h2 id="2016-01-18">2016-01-18</h2>
<ul>
<li>Change &ldquo;Extension material&rdquo; to &ldquo;Extension Material&rdquo; in input-forms.xml (a mistake that fell through the cracks when we fixed the others in DSpace 4 era)</li>
</ul>
<h2 id="2016-01-19">2016-01-19</h2>
<ul>
<li>Work on tweaks and updates for the social sharing icons on item pages: add Delicious and Mendeley (from Academicons), make links open in new windows, and set the icon color to the theme&rsquo;s primary color (<a href="https://github.com/ilri/DSpace/issues/157">#157</a>)</li>
<li>Tweak date-based facets to show more values in drill-down ranges (<a href="https://github.com/ilri/DSpace/issues/162">#162</a>)</li>
<li>Need to remember to clear the Cocoon cache after deployment or else you don&rsquo;t see the new ranges immediately</li>
<li>Set up recipe on IFTTT to tweet new items from the CGSpace Atom feed to my twitter account</li>
<li>Altmetrics&rsquo; support for Handles is kinda weak, so they can&rsquo;t associate our items with DOIs until they are tweeted or blogged, etc first.</li>
</ul>
<h2 id="2016-01-21">2016-01-21</h2>
<ul>
<li>Still waiting for my IFTTT recipe to fire, two days later</li>
<li>It looks like the Atom feed on CGSpace hasn&rsquo;t changed in two days, but there have definitely been new items</li>
<li>The RSS feed is nearly as old, but has different old items there</li>
<li>On a hunch I cleared the Cocoon cache and now the feeds are fresh</li>
<li>Looks like there is configuration option related to this, <code>webui.feed.cache.age</code>, which defaults to 48 hours, though I&rsquo;m not sure what relation it has to the Cocoon cache</li>
<li>In any case, we should change this cache to be something more like 6 hours, as we publish new items several times per day.</li>
<li>Work around a CSS issue with long URLs in the item view (<a href="https://github.com/ilri/DSpace/issues/172">#172</a>)</li>
</ul>
<h2 id="2016-01-25">2016-01-25</h2>
<ul>
<li>Re-deploy CGSpace and DSpace Test with latest <code>5_x-prod</code> branch</li>
<li>This included the social icon fixes/updates, date-based facet tweaks, reducing the feed cache age, and fixing a layout issue in XMLUI item view when an item had long URLs</li>
</ul>
<h2 id="2016-01-26">2016-01-26</h2>
<ul>
<li>Run nginx updates on CGSpace and DSpace Test (<a href="http://mailman.nginx.org/pipermail/nginx/2016-January/049700.html">1.8.1 and 1.9.10, respectively</a>)</li>
<li>Run updates on DSpace Test and reboot for new Linode kernel <code>Linux 4.4.0-x86_64-linode63</code> (first update in months)</li>
</ul>
<h2 id="2016-01-28">2016-01-28</h2>
<ul>
<li>
<p>Start looking at importing some Bioversity data that had been prepared earlier this week</p>
</li>
<li>
<p>While checking the data I noticed something strange, there are 79 items but only 8 unique PDFs:</p>
<p>$ ls SimpleArchiveForBio/ | wc -l
79
$ find SimpleArchiveForBio/ -iname &ldquo;*.pdf&rdquo; -exec basename {} ; | sort -u | wc -l
8</p>
</li>

<h2 id="2016-01-29">2016-01-29</h2>
<ul>
<li>Add five missing center-specific subjects to XMLUI item view (<a href="https://github.com/ilri/DSpace/issues/174">#174</a>)</li>

<ul>
<li>Looking at some DAGRIS data for Abenet Yabowork</li>
<li>Lots of issues with spaces, newlines, etc causing the import to fail</li>
<li>I noticed we have a very <em>interesting</em> list of countries on CGSpace:</li>
</ul>
<p><img src="/cgspace-notes/2016/02/cgspace-countries.png" alt="CGSpace country list"></p>
<ul>
<li>Not only are there 49,000 countries, we have some blanks (25)&hellip;</li>
<li>Also, lots of things like &ldquo;COTE D`LVOIRE&rdquo; and &ldquo;COTE D IVOIRE&rdquo;</li>
</ul>
<h2 id="2016-02-06">2016-02-06</h2>
<ul>
<li>Found a way to get items with null/empty metadata values from SQL</li>
<li>First, find the <code>metadata_field_id</code> for the field you want from the <code>metadatafieldregistry</code> table:</li>
</ul>
<pre tabindex="0"><code>dspacetest=# select * from metadatafieldregistry;
</code></pre><ul>
<li>In this case our country field is 78</li>
<li>Now find all resources with type 2 (item) that have null/empty values for that field:</li>
</ul>
<pre tabindex="0"><code>dspacetest=# select resource_id from metadatavalue where resource_type_id=2 and metadata_field_id=78 and (text_value=&#39;&#39; OR text_value IS NULL);
</code></pre><ul>
<li>Then you can find the handle that owns it from its <code>resource_id</code>:</li>
</ul>
<pre tabindex="0"><code>dspacetest=# select handle from item, handle where handle.resource_id = item.item_id AND item.item_id = &#39;22678&#39;;
</code></pre><ul>
<li>It&rsquo;s 25 items so editing in the web UI is annoying, let&rsquo;s try SQL!</li>
</ul>
<pre tabindex="0"><code>dspacetest=# delete from metadatavalue where metadata_field_id=78 and text_value=&#39;&#39;;
DELETE 25
</code></pre><ul>
<li>After that perhaps a regular <code>dspace index-discovery</code> (no -b) <em>should</em> suffice&hellip;</li>
<li>Hmm, I indexed, cleared the Cocoon cache, and restarted Tomcat but the 25 &ldquo;|||&rdquo; countries are still there</li>
<li>Maybe I need to do a full re-index&hellip;</li>
<li>Yep! The full re-index seems to work.</li>
<li>Process the empty countries on CGSpace</li>
</ul>
<h2 id="2016-02-07">2016-02-07</h2>
<ul>
<li>Working on cleaning up Abenet&rsquo;s DAGRIS data with OpenRefine</li>
<li>I discovered two really nice functions in OpenRefine: <code>value.trim()</code> and <code>value.escape(&quot;javascript&quot;)</code> which shows whitespace characters like <code>\r\n</code>!</li>
<li>For some reason when you import an Excel file into OpenRefine it exports dates like 1949 to 1949.0 in the CSV</li>
<li>I re-import the resulting CSV and run a GREL on the date issued column: <code>value.replace(&quot;\.0&quot;, &quot;&quot;)</code></li>
<li>I need to start running DSpace in Mac OS X instead of a Linux VM</li>
<li>Install PostgreSQL from homebrew, then configure and import CGSpace database dump:</li>
</ul>
<pre tabindex="0"><code>$ postgres -D /opt/brew/var/postgres
$ createuser --superuser postgres
$ createuser --pwprompt dspacetest
$ createdb -O dspacetest --encoding=UNICODE dspacetest
$ psql postgres

postgres=# \q
$ pg_restore -O -U dspacetest -d dspacetest ~/Downloads/cgspace_2016-02-07.backup
$ psql postgres
postgres=# alter user dspacetest nocreateuser;
postgres=# \q
$ vacuumdb dspacetest
$ psql -U dspacetest -f ~/src/git/DSpace/dspace/etc/postgres/update-sequences.sql dspacetest -h localhost
</code></pre><ul>
<li>After building and running a <code>fresh_install</code> I symlinked the webapps into Tomcat&rsquo;s webapps folder:</li>
</ul>
<pre tabindex="0"><code>$ mv /opt/brew/Cellar/tomcat/8.0.30/libexec/webapps/ROOT /opt/brew/Cellar/tomcat/8.0.30/libexec/webapps/ROOT.orig
$ ln -sfv ~/dspace/webapps/xmlui /opt/brew/Cellar/tomcat/8.0.30/libexec/webapps/ROOT

$ ln -sfv ~/dspace/webapps/solr /opt/brew/Cellar/tomcat/8.0.30/libexec/webapps/solr
$ /opt/brew/Cellar/tomcat/8.0.30/bin/catalina start
</code></pre><ul>
<li>Add CATALINA_OPTS in <code>/opt/brew/Cellar/tomcat/8.0.30/libexec/bin/setenv.sh</code>, as this script is sourced by the <code>catalina</code> startup script</li>
<li>For example:</li>
</ul>
<pre tabindex="0"><code>CATALINA_OPTS=&#34;-Djava.awt.headless=true -Xms2048m -Xmx2048m -XX:MaxPermSize=256m -XX:+UseConcMarkSweepGC -Dfile.encoding=UTF-8&#34;
</code></pre><ul>
<li>After verifying that the site is working, start a full index:</li>
</ul>
<pre tabindex="0"><code>$ ~/dspace/bin/dspace index-discovery -b
</code></pre><h2 id="2016-02-08">2016-02-08</h2>
<ul>
<li>Finish cleaning up and importing ~400 DAGRIS items into CGSpace</li>
<li>Whip up some quick CSS to make the button in the submission workflow use the XMLUI theme&rsquo;s brand colors (<a href="https://github.com/ilri/DSpace/issues/154">#154</a>)</li>

<h2 id="2016-02-09">2016-02-09</h2>
<ul>
<li>Re-sync DSpace Test with CGSpace</li>
<li>Help Sisay with OpenRefine</li>
<li>Enable HTTPS on DSpace Test using Let&rsquo;s Encrypt:</li>
</ul>
<pre tabindex="0"><code>$ cd ~/src/git
$ git clone https://github.com/letsencrypt/letsencrypt
$ cd letsencrypt
$ sudo service nginx stop
# add port 443 to firewall rules
$ ./letsencrypt-auto certonly --standalone -d dspacetest.cgiar.org
$ sudo service nginx start
$ ansible-playbook dspace.yml -l linode02 -t nginx,firewall -u aorth --ask-become-pass
</code></pre><ul>
<li>We should install it in /opt/letsencrypt and then script the renewal script, but first we have to wire up some variables and template stuff based on the script here: <a href="https://letsencrypt.org/howitworks/">https://letsencrypt.org/howitworks/</a></li>
<li>I had to export some CIAT items that were being cleaned up on the test server and I noticed their <code>dc.contributor.author</code> fields have DSpace 5 authority index UUIDs&hellip;</li>
<li>To clean those up in OpenRefine I used this GREL expression: <code>value.replace(/::\w{8}-\w{4}-\w{4}-\w{4}-\w{12}::600/,&quot;&quot;)</code></li>
<li>Getting more and more hangs on DSpace Test, seemingly random but also during CSV import</li>
<li>Logs don&rsquo;t always show anything right when it fails, but eventually one of these appears:</li>
</ul>
<pre tabindex="0"><code>org.dspace.discovery.SearchServiceException: Error while processing facet fields: java.lang.OutOfMemoryError: Java heap space
</code></pre><ul>
<li>or</li>
</ul>
<pre tabindex="0"><code>Caused by: java.util.NoSuchElementException: Timeout waiting for idle object
</code></pre><ul>
<li>Right now DSpace Test&rsquo;s Tomcat heap is set to 1536m and we have quite a bit of free RAM:</li>
</ul>
<pre tabindex="0"><code># free -m
total used free shared buffers cached
Mem: 3950 3902 48 9 37 1311
-/+ buffers/cache: 2552 1397

</code></pre><ul>
<li>So I&rsquo;ll bump up the Tomcat heap to 2048 (CGSpace production server is using 3GB)</li>
</ul>
<h2 id="2016-02-11">2016-02-11</h2>
<ul>
<li>Massaging some CIAT data in OpenRefine</li>
<li>There are 1200 records that have PDFs, and will need to be imported into CGSpace</li>
<li>I created a <code>filename</code> column based on the <code>dc.identifier.url</code> column using the following transform:</li>
</ul>
<pre tabindex="0"><code>value.split(&#39;/&#39;)[-1]
</code></pre><ul>
<li>Then I wrote a tool called <a href="https://gist.github.com/alanorth/2206f24483fe5f0454fc"><code>generate-thumbnails.py</code></a> to download the PDFs and generate thumbnails for them, for example:</li>
</ul>
<pre tabindex="0"><code>$ ./generate-thumbnails.py ciat-reports.csv

&gt; Downloading 64661.pdf
&gt; Creating thumbnail for 64661.pdf
Processing 64195.pdf
&gt; Downloading 64195.pdf
&gt; Creating thumbnail for 64195.pdf
</code></pre><h2 id="2016-02-12">2016-02-12</h2>
<ul>
<li>Looking at CIAT&rsquo;s records again, there are some problems with a dozen or so files (out of 1200)</li>
<li>A few items are using the same exact PDF</li>
<li>A few items are using HTM or DOC files</li>
<li>A few items link to PDFs on IFPRI&rsquo;s e-Library or Research Gate</li>
<li>A few items have no item</li>
<li>Also, I&rsquo;m not sure if we import these items, will be remove the <code>dc.identifier.url</code> field from the records?</li>
</ul>
<h2 id="2016-02-12-1">2016-02-12</h2>
<ul>
<li>Looking at CIAT&rsquo;s records again, there are some files linking to PDFs on Slide Share, Embrapa, UEA UK, and Condesan, so I&rsquo;m not sure if we can use those</li>
<li>265 items have dirty, URL-encoded filenames:</li>
</ul>
<pre tabindex="0"><code>$ ls | grep -c -E &#34;%&#34;
265
</code></pre><ul>
<li>I suggest that we import ~850 or so of the clean ones first, then do the rest after I can find a clean/reliable way to decode the filenames</li>
<li>This python2 snippet seems to work in the CLI, but not so well in OpenRefine:</li>
</ul>
<pre tabindex="0"><code>$ python -c &#34;import urllib, sys; print urllib.unquote(sys.argv[1])&#34; CIAT_COLOMBIA_000169_T%C3%A9cnicas_para_el_aislamiento_y_cultivo_de_protoplastos_de_yuca.pdf
CIAT_COLOMBIA_000169_Técnicas_para_el_aislamiento_y_cultivo_de_protoplastos_de_yuca.pdf
</code></pre><ul>
<li>Merge pull requests for submission form theming (<a href="https://github.com/ilri/DSpace/pull/178">#178</a>) and missing center subjects in XMLUI item views (<a href="https://github.com/ilri/DSpace/pull/176">#176</a>)</li>
<li>They will be deployed on CGSpace the next time I re-deploy</li>
</ul>
<h2 id="2016-02-16">2016-02-16</h2>
<ul>
<li>Turns out OpenRefine has an unescape function!</li>
</ul>
<pre tabindex="0"><code>value.unescape(&#34;url&#34;)
</code></pre><ul>
<li>This turns the URLs into human-readable versions that we can use as proper filenames</li>
<li>Run web server and system updates on DSpace Test and reboot</li>
<li>To merge <code>dc.identifier.url</code> and <code>dc.identifier.url[]</code>, rename the second column so it doesn&rsquo;t have the brackets, like <code>dc.identifier.url2</code></li>
<li>Then you create a facet for blank values on each column, show the rows that have values for one and not the other, then transform each independently to have the contents of the other, with &ldquo;||&rdquo; in between</li>
<li>Work on Python script for parsing and downloading PDF records from <code>dc.identifier.url</code></li>
<li>To get filenames from <code>dc.identifier.url</code>, create a new column based on this transform: <code>forEach(value.split('||'), v, v.split('/')[-1]).join('||')</code></li>
<li>This also works for records that have multiple URLs (separated by &ldquo;||&rdquo;)</li>
</ul>
<h2 id="2016-02-17">2016-02-17</h2>
<ul>
<li>Re-deploy CGSpace, run all system updates, and reboot</li>
<li>More work on CIAT data, cleaning and doing a last metadata-only import into DSpace Test</li>
<li>SAFBuilder has a bug preventing it from processing filenames containing more than one underscore</li>
<li>Need to re-process the filename column to replace multiple underscores with one: <code>value.replace(/_{2,}/, &quot;_&quot;)</code></li>
</ul>
<h2 id="2016-02-20">2016-02-20</h2>
<ul>
<li>Turns out the &ldquo;bug&rdquo; in SAFBuilder isn&rsquo;t a bug, it&rsquo;s a feature that allows you to encode extra information like the destintion bundle in the filename</li>
<li>Also, it seems DSpace&rsquo;s SAF import tool doesn&rsquo;t like importing filenames that have accents in them:</li>
</ul>
<pre tabindex="0"><code>java.io.FileNotFoundException: /usr/share/tomcat7/SimpleArchiveFormat/item_1021/CIAT_COLOMBIA_000075_Medición_de_palatabilidad_en_forrajes.pdf (No such file or directory)
</code></pre><ul>
<li>Need to rename files to have no accents or umlauts, etc&hellip;</li>
<li>Useful custom text facet for URLs ending with &ldquo;.pdf&rdquo;: <code>value.endsWith(&quot;.pdf&quot;)</code></li>
</ul>
<h2 id="2016-02-22">2016-02-22</h2>
<ul>
<li>To change Spanish accents to ASCII in OpenRefine:</li>
</ul>
<pre tabindex="0"><code>value.replace(&#39;ó&#39;,&#39;o&#39;).replace(&#39;í&#39;,&#39;i&#39;).replace(&#39;á&#39;,&#39;a&#39;).replace(&#39;é&#39;,&#39;e&#39;).replace(&#39;ñ&#39;,&#39;n&#39;)
</code></pre><ul>
<li>But actually, the accents might not be an issue, as I can successfully import files containing Spanish accents on my Mac</li>
<li>On closer inspection, I can import files with the following names on Linux (DSpace Test):</li>
</ul>
<pre tabindex="0"><code>Bitstream: tést.pdf
Bitstream: tést señora.pdf
Bitstream: tést señora alimentación.pdf
</code></pre><ul>
<li>Seems it could be something with the HFS+ filesystem actually, as it&rsquo;s not UTF-8 (<a href="http://www.cio.com/article/2868393/linus-torvalds-apples-hfs-is-probably-the-worst-file-system-ever.html">it&rsquo;s something like UCS-2</a>)</li>
<li>HFS+ stores filenames as a string, and filenames with accents get stored as <a href="https://blog.vrypan.net/2012/11/13/hfsplus-unicode-and-accented-chars/">character+accent</a> whereas Linux&rsquo;s ext4 stores them as an array of bytes</li>
<li>Running the SAFBuilder on Mac OS X works if you&rsquo;re going to import the resulting bundle on Mac OS X, but if your DSpace is running on Linux you need to run the SAFBuilder there where the filesystem&rsquo;s encoding matches</li>
</ul>
<h2 id="2016-02-29">2016-02-29</h2>
<ul>
<li>Got notified by some CIFOR colleagues that the Google Scholar team had contacted them about CGSpace&rsquo;s incorrect ordering of authors in Google Scholar metadata</li>
<li>Turns out there is a patch, and it was merged in DSpace 5.4: <a href="https://jira.duraspace.org/browse/DS-2679">https://jira.duraspace.org/browse/DS-2679</a></li>
<li>I&rsquo;ve merged it into our <code>5_x-prod</code> branch that is currently based on DSpace 5.1</li>
<li>We found a bug when a user searches from the homepage, sorts the results, and then tries to click &ldquo;View More&rdquo; in a sidebar facet</li>
<li>I am not sure what causes it yet, but I opened an issue for it: <a href="https://github.com/ilri/DSpace/issues/179">https://github.com/ilri/DSpace/issues/179</a></li>
<li>Have more problems with SAFBuilder on Mac OS X</li>
<li>Now it doesn&rsquo;t recognize description hints in the filename column, like: <code>test.pdf__description:Blah</code></li>
<li>But on Linux it works fine</li>
<li>Trying to test Atmire&rsquo;s series of stats and CUA fixes from January and February, but their branch history is really messy and it&rsquo;s hard to see what&rsquo;s going on</li>
<li>Rebasing their branch on top of our production branch results in a broken Tomcat, so I&rsquo;m going to tell them to fix their history and make a proper pull request</li>
<li>Looking at the filenames for the CIAT Reports, some have some really ugly characters, like: <code>'</code> or <code>,</code> or <code>=</code> or <code>[</code> or <code>]</code> or <code>(</code> or <code>)</code> or <code>_.pdf</code> or <code>._</code> etc</li>
<li>It&rsquo;s tricky to parse those things in some programming languages so I&rsquo;d rather just get rid of the weird stuff now in OpenRefine:</li>
</ul>
<pre tabindex="0"><code>value.replace(&#34;&#39;&#34;,&#39;&#39;).replace(&#39;_=_&#39;,&#39;_&#39;).replace(&#39;,&#39;,&#39;&#39;).replace(&#39;[&#39;,&#39;&#39;).replace(&#39;]&#39;,&#39;&#39;).replace(&#39;(&#39;,&#39;&#39;).replace(&#39;)&#39;,&#39;&#39;).replace(&#39;_.pdf&#39;,&#39;.pdf&#39;).replace(&#39;._&#39;,&#39;_&#39;)
</code></pre><ul>
<li>Finally import the 1127 CIAT items into CGSpace: <a href="https://cgspace.cgiar.org/handle/10568/35710">https://cgspace.cgiar.org/handle/10568/35710</a></li>
<li>Re-deploy CGSpace with the Google Scholar fix, but I&rsquo;m waiting on the Atmire fixes for now, as the branch history is ugly</li>

<ul>
<li>Looking at issues with author authorities on CGSpace</li>
<li>For some reason we still have the <code>index-lucene-update</code> cron job active on CGSpace, but I&rsquo;m pretty sure we don&rsquo;t need it as of the latest few versions of Atmire&rsquo;s Listings and Reports module</li>
<li>Reinstall my local (Mac OS X) DSpace stack with Tomcat 7, PostgreSQL 9.3, and Java JDK 1.7 to match environment on CGSpace server</li>

<ul>
<li>Troubleshooting the issues with the slew of commits for Atmire modules in <a href="https://github.com/ilri/DSpace/pull/182">#182</a></li>
<li>Their changes on <code>5_x-dev</code> branch work, but it is messy as hell with merge commits and old branch base</li>
<li>When I rebase their branch on the latest <code>5_x-prod</code> I get blank white pages</li>
<li>I identified one commit that causes the issue and let them know</li>
<li>Restart DSpace Test, as it seems to have crashed after Sisay tried to import some CSV or zip or something:</li>

<li>Request new documentation for Atmire CUA and L&amp;R modules, as ours are from 2013</li>
<li>Walk Sisay through some data cleaning workflows in OpenRefine</li>
<li>Start cleaning up the configuration for Atmire&rsquo;s CUA module (<a href="https://github.com/ilri/DSpace/issues/185">#184</a>)</li>

<h2 id="2016-03-11">2016-03-11</h2>
<ul>
<li>As I was looking at the CUA config I realized our Discovery config is all messed up and confusing</li>
<li>I&rsquo;ve opened an issue to track some of that work (<a href="https://github.com/ilri/DSpace/issues/186">#186</a>)</li>
<li>I did some major cleanup work on Discovery and XMLUI stuff related to the <code>dc.type</code> indexes (<a href="https://github.com/ilri/DSpace/pull/187">#187</a>)</li>
<li>We had been confusing <code>dc.type</code> (a Dublin Core value) with <code>dc.type.output</code> (a value we invented) for a few years and it had permeated all aspects of our data, indexes, item displays, etc.</li>
<li>There is still some more work to be done to remove references to old <code>outputtype</code> and <code>output</code></li>
</ul>
<h2 id="2016-03-14">2016-03-14</h2>
<ul>
<li>Fix some items that had invalid dates (I noticed them in the log during a re-indexing)</li>
<li>Reset <code>search.index.*</code> to the default, as it is only used by Lucene (deprecated by Discovery in DSpace 5.x): <a href="https://github.com/ilri/DSpace/pull/188">#188</a></li>
<li>Make titles in Discovery and Browse by more consistent (singular, sentence case, etc) (<a href="https://github.com/ilri/DSpace/issues/186">#186</a>)</li>
<li>Also four or so center-specific subject strings were missing for Discovery</li>
</ul>

<li>It seems this <code>dc.language</code> field isn&rsquo;t really used, but we should delete these values</li>
<li>Also, <code>dc.language.iso</code> has some weird values, like &ldquo;En&rdquo; and &ldquo;English&rdquo;</li>
</ul>
<h2 id="2016-03-17">2016-03-17</h2>
<ul>
<li>It turns out <code>hi</code> is the ISO 639 language code for Hindi, but these should be in <code>dc.language.iso</code> instead of <code>dc.language</code></li>
<li>I fixed the eleven items with <code>hi</code> as well as some using the incorrect <code>vn</code> for Vietnamese</li>
<li>Start discussing CG core with Abenet and Sisay</li>
<li>Re-sync CGSpace database to DSpace Test for Atmire to do some tests about the problematic CUA patches</li>
<li>The patches work fine with a clean database, so the error was caused by some mismatch in CUA versions and the database during my testing</li>

<ul>
<li>Merge Atmire fixes into <code>5_x-prod</code></li>
<li>Discuss thumbnails with Francesca from Bioversity</li>
<li>Some of their items end up with thumbnails that have a big white border around them:</li>

<p><img src="/cgspace-notes/2016/03/bioversity-thumbnail-bad.jpg" alt="Excessive whitespace in thumbnail"></p>

<ul>
<li>Fix 66 site errors in Google&rsquo;s webmaster tools</li>
<li>I looked at a bunch of them and they were old URLs, weird things linked from non-existent items, etc, so I just marked them all as fixed</li>
<li>We also have 1,300 &ldquo;soft 404&rdquo; errors for URLs like: <a href="https://cgspace.cgiar.org/handle/10568/440/browse?type=bioversity">https://cgspace.cgiar.org/handle/10568/440/browse?type=bioversity</a></li>
<li>I&rsquo;ve marked them as fixed as well since the ones I tested were working fine</li>
<li>This raises another question, as many of these pages are linked from Discovery search results and might create a duplicate content problem&hellip;</li>
<li>Results pages like this give items that Google already knows from the sitemap: <a href="https://cgspace.cgiar.org/discover?filtertype=author&amp;filter_relational_operator=equals&amp;filter=Orth%2C+A">https://cgspace.cgiar.org/discover?filtertype=author&amp;filter_relational_operator=equals&amp;filter=Orth%2C+A</a>.</li>
<li>There are some access denied errors on JSPUI links (of course! we forbid them!), but I&rsquo;m not sure why Google is trying to index them&hellip;</li>
<li>For example:
<ul>
<li>This: <a href="https://cgspace.cgiar.org/jspui/bitstream/10568/809/1/main-page.pdf">https://cgspace.cgiar.org/jspui/bitstream/10568/809/1/main-page.pdf</a></li>
<li>Linked from: <a href="https://cgspace.cgiar.org/jspui/handle/10568/809">https://cgspace.cgiar.org/jspui/handle/10568/809</a></li>
</ul>
</li>
<li>I will mark these errors as resolved because they are returning HTTP 403 on purpose, for a long time!</li>
<li>Google says the first time it saw this particular error was September 29, 2015&hellip; so maybe it accidentally saw it somehow&hellip;</li>
<li>On a related note, we have 51,000 items indexed from the sitemap, but 500,000 items in the Google index, so we DEFINITELY have a problem with duplicate content</li>
</ul>
<p><img src="/cgspace-notes/2016/03/google-index.png" alt="CGSpace pages in Google index"></p>
<ul>
<li>Turns out this is a problem with DSpace&rsquo;s <code>robots.txt</code>, and there&rsquo;s a Jira ticket since December, 2015: <a href="https://jira.duraspace.org/browse/DS-2962">https://jira.duraspace.org/browse/DS-2962</a></li>
<li>I am not sure if I want to apply it yet</li>
<li>For now I&rsquo;ve just set a bunch of these dynamic pages to not appear in search results by using the URL Parameters tool in Webmaster Tools</li>
</ul>
<p><img src="/cgspace-notes/2016/03/url-parameters.png" alt="URL parameters cause millions of dynamic pages">
<img src="/cgspace-notes/2016/03/url-parameters2.png" alt="Setting pages with the filter_0 param not to show in search results"></p>

<li>Move AVCD collection to new community and update <code>move_collection.sh</code> script: <a href="https://gist.github.com/alanorth/392c4660e8b022d99dfa">https://gist.github.com/alanorth/392c4660e8b022d99dfa</a></li>
<li>It seems Feedburner can do HTTPS now, so we might be able to update our feeds and simplify the nginx configs</li>
<li>De-deploy CGSpace with latest <code>5_x-prod</code> branch</li>
<li>Run updates on CGSpace and reboot server (new kernel, <code>4.5.0</code>)</li>
<li>Deploy Let&rsquo;s Encrypt certificate for cgspace.cgiar.org, but still need to work it into the ansible playbooks</li>
</ul>
<h2 id="2016-03-22">2016-03-22</h2>

<li>Seems we only want <code>AccessStep</code> because <code>UploadWithEmbargoStep</code> disables the ability to edit embargos at the item level</li>
<li>This pull request enables the ability to set an item-level embargo during submission: <a href="https://github.com/ilri/DSpace/pull/203">https://github.com/ilri/DSpace/pull/203</a></li>
<li>I figured out that the problem with Listings and Reports was because I disabled the <code>search.index.*</code> last week, and they are still used by JSPUI apparently</li>
<li>This pull request re-enables them: <a href="https://github.com/ilri/DSpace/pull/202">https://github.com/ilri/DSpace/pull/202</a></li>
<li>Re-deploy DSpace Test, run all system updates, and restart the server</li>
<li>Looks like the Listings and Reports fix was NOT due to the search indexes (which are actually not used), and rather due to the filter configuration in the Listings and Reports config</li>
<li>This pull request simply updates the config for the dc.type.output → dc.type change that was made last week: <a href="https://github.com/ilri/DSpace/pull/204">https://github.com/ilri/DSpace/pull/204</a></li>
<li>Deploy robots.txt fix, embargo for item submissions, and listings and reports fix on CGSpace</li>

<h2 id="2016-03-29">2016-03-29</h2>
<ul>
<li>Skype meeting with Peter and Addis team to discuss metadata changes for Dublin Core, CGcore, and CGSpace-specific fields</li>
<li>We decided to proceed with some deletes first, then identify CGSpace-specific fields to clean/move to <code>cg.*</code>, and then worry about broader changes to DC</li>
<li>Before we move or rename and fields we need to circulate a list of fields we intend to change to CCAFS, CWPF, etc who might be harvesting the fields</li>
<li>After all of this we need to start implementing controlled vocabularies for fields, either with the Javascript lookup or like existing ILRI subjects</li>

Looking at log file use on CGSpace and notice that we need to work on our cron setup a bit
We are backing up all logs in the log folder, including useless stuff like solr, cocoon, handle-plugin, etc
After running DSpace for over five years I&rsquo;ve never needed to look in any other log file than dspace.log, leave alone one from last year!
This will save us a few gigs of backup space we&rsquo;re paying for on S3

<li>The two most often requesters are in Ethiopia and Colombia: 213.55.99.121 and 181.118.144.29</li>
<li>100% of the requests coming from Ethiopia are like this and result in an HTTP 500:</li>

<li>For now I&rsquo;ll block just the Ethiopian IP</li>
<li>The owner of that application has said that the <code>NaN</code> (not a number) is an error in his code and he&rsquo;ll fix it</li>
</ul>
<h2 id="2016-05-03">2016-05-03</h2>
<ul>
<li>Update nginx to 1.10.x branch on CGSpace</li>
<li>Fix a reference to <code>dc.type.output</code> in Discovery that I had missed when we migrated to <code>dc.type</code> last month (<a href="https://github.com/ilri/DSpace/pull/223">#223</a>)</li>
</ul>

<li>DSpace Test is down, <code>catalina.out</code> has lots of messages about heap space from some time yesterday (!)</li>
<li>It looks like Sisay was doing some batch imports</li>
<li>Hmm, also disk space is full</li>
<li>I decided to blow away the solr indexes, since they are 50GB and we don&rsquo;t really need all the Atmire stuff there right now</li>
<li>I will re-generate the Discovery indexes after re-deploying</li>
<li>Testing <code>renew-letsencrypt.sh</code> script for nginx</li>

<li>Seems to work well</li>
</ul>
<h2 id="2016-05-10">2016-05-10</h2>
<ul>
<li>Start looking at more metadata migrations</li>
<li>There are lots of fields in <code>dcterms</code> namespace that look interesting, like:
<ul>
<li>dcterms.type</li>
<li>dcterms.spatial</li>
</ul>
</li>
<li>Not sure what <code>dcterms</code> is&hellip;</li>
<li>Looks like these were <a href="https://wiki.lyrasis.org/display/DSDOC5x/Metadata+and+Bitstream+Format+Registries#MetadataandBitstreamFormatRegistries-DublinCoreTermsRegistry(DCTERMS)">added in DSpace 4</a> to allow for future work to make DSpace more flexible</li>
<li>CGSpace&rsquo;s <code>dc</code> registry has 96 items, and the default DSpace one has 73.</li>
</ul>
<h2 id="2016-05-11">2016-05-11</h2>
<ul>
<li>
<p>Identify and propose the next phase of CGSpace fields to migrate:</p>
<ul>
<li>dc.title.jtitle → cg.title.journal</li>
<li>dc.identifier.status → cg.identifier.status</li>
<li>dc.river.basin → cg.river.basin</li>
<li>dc.Species → cg.species</li>
<li>dc.targetaudience → cg.targetaudience</li>
<li>dc.fulltextstatus → cg.fulltextstatus</li>
<li>dc.editon → cg.edition</li>
<li>dc.isijournal → cg.isijournal</li>
</ul>
</li>
<li>
<p>Start a test rebase of the <code>5_x-prod</code> branch on top of the <code>dspace-5.5</code> tag</p>
</li>
<li>
<p>There were a handful of conflicts that I didn&rsquo;t understand</p>
</li>
<li>
<p>After completing the rebase I tried to build with the module versions Atmire had indicated as being 5.5 ready but I got this error:</p>
</li>
</ul>
<pre tabindex="0"><code>[ERROR] Failed to execute goal on project additions: Could not resolve dependencies for project org.dspace.modules:additions:jar:5.5: Could not find artifact com.atmire:atmire-metadata-quality-api:jar:5.5-2.10.1-0 in sonatype-releases (https://oss.sonatype.org/content/repositories/releases/) -&gt; [Help 1]
</code></pre><ul>
<li>I&rsquo;ve sent them a question about it</li>
<li>A user mentioned having problems with uploading a 33 MB PDF</li>
<li>I told her I would increase the limit temporarily tomorrow morning</li>
<li>Turns out she was able to decrease the size of the PDF so we didn&rsquo;t have to do anything</li>
</ul>
<h2 id="2016-05-12">2016-05-12</h2>
<ul>
<li>Looks like the issue that Abenet was having a few days ago with &ldquo;Connection Reset&rdquo; in Firefox might be due to a Firefox 46 issue: <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1268775">https://bugzilla.mozilla.org/show_bug.cgi?id=1268775</a></li>
<li>I finally found a copy of the latest CG Core metadata guidelines and it looks like we can add a few more fields to our next migration:
<ul>
<li>dc.rplace.region → cg.coverage.region</li>
<li>dc.cplace.country → cg.coverage.country</li>
</ul>
</li>
<li>Questions for CG people:
<ul>
<li>Our <code>dc.place</code> and <code>dc.srplace.subregion</code> could both map to <code>cg.coverage.admin-unit</code>?</li>
<li>Should we use <code>dc.contributor.crp</code> or <code>cg.contributor.crp</code> for the CRP (ours is <code>dc.crsubject.crpsubject</code>)?</li>
<li>Our <code>dc.contributor.affiliation</code> and <code>dc.contributor.corporate</code> could both map to <code>dc.contributor</code> and possibly <code>dc.contributor.center</code> depending on if it&rsquo;s a CG center or not</li>
<li><code>dc.title.jtitle</code> could either map to <code>dc.publisher</code> or <code>dc.source</code> depending on how you read things</li>
</ul>
</li>
<li>Found ~200 messed up CIAT values in <code>dc.publisher</code>:</li>
</ul>
<pre tabindex="0"><code># select text_value from metadatavalue where resource_type_id=2 and metadata_field_id=39 and text_value similar to &#34;% %&#34;;
</code></pre><h2 id="2016-05-13">2016-05-13</h2>
<ul>
<li>More theorizing about CGcore</li>
<li>Add two new fields:
<ul>
<li>dc.srplace.subregion → cg.coverage.admin-unit</li>
<li>dc.place → cg.place</li>
</ul>
</li>
<li><code>dc.place</code> is our own field, so it&rsquo;s easy to move</li>
<li>I&rsquo;ve removed <code>dc.title.jtitle</code> from the list for now because there&rsquo;s no use moving it out of DC until we know where it will go (see discussion yesterday)</li>
</ul>
<h2 id="2016-05-18">2016-05-18</h2>
<ul>
<li>Work on 707 CCAFS records</li>
<li>They have thumbnails on Flickr and elsewhere</li>
<li>In OpenRefine I created a new <code>filename</code> column based on the <code>thumbnail</code> column with the following GREL:</li>
</ul>
<pre tabindex="0"><code>if(cells[&#39;thumbnails&#39;].value.contains(&#39;hqdefault&#39;), cells[&#39;thumbnails&#39;].value.split(&#39;/&#39;)[-2] + &#39;.jpg&#39;, cells[&#39;thumbnails&#39;].value.split(&#39;/&#39;)[-1])
</code></pre><ul>
<li>Because ~400 records had the same filename on Flickr (hqdefault.jpg) but different UUIDs in the URL</li>
<li>So for the <code>hqdefault.jpg</code> ones I just take the UUID (-2) and use it as the filename</li>
<li>Before importing with SAFBuilder I tested adding &ldquo;__bundle:THUMBNAIL&rdquo; to the <code>filename</code> column and it works fine</li>
</ul>
<h2 id="2016-05-19">2016-05-19</h2>
<ul>
<li>More quality control on <code>filename</code> field of CCAFS records to make processing in shell and SAFBuilder more reliable:</li>
</ul>
<pre tabindex="0"><code>value.replace(&#39;_&#39;,&#39;&#39;).replace(&#39;-&#39;,&#39;&#39;)
</code></pre><ul>
<li>We need to hold off on moving <code>dc.Species</code> to <code>cg.species</code> because it is only used for plants, and might be better to move it to something like <code>cg.species.plant</code></li>
<li>And <code>dc.identifier.fund</code> is MOSTLY used for CPWF project identifier but has some other sponsorship things
<ul>
<li>We should move PN*, SG*, CBA, IA, and PHASE* values to <code>cg.identifier.cpwfproject</code></li>
<li>The rest, like BMGF and USAID etc, might have to go to either <code>dc.description.sponsorship</code> or <code>cg.identifier.fund</code> (not sure yet)</li>
<li>There are also some mistakes in CPWF&rsquo;s things, like &ldquo;PN 47&rdquo;</li>
<li>This ought to catch all the CPWF values (there don&rsquo;t appear to be and SG* values):</li>
</ul>
</li>
</ul>
<pre tabindex="0"><code># select text_value from metadatavalue where resource_type_id=2 and metadata_field_id=75 and (text_value like &#39;PN%&#39; or text_value like &#39;PHASE%&#39; or text_value = &#39;CBA&#39; or text_value = &#39;IA&#39;);
</code></pre><h2 id="2016-05-20">2016-05-20</h2>
<ul>
<li>More work on CCAFS Video and Images records</li>
<li>For SAFBuilder we need to modify filename column to have the thumbnail bundle:</li>
</ul>
<pre tabindex="0"><code>value + &#34;__bundle:THUMBNAIL&#34;
</code></pre><ul>
<li>Also, I fixed some weird characters using OpenRefine&rsquo;s transform with the following GREL:</li>
</ul>
<pre tabindex="0"><code>value.replace(/\u0081/,&#39;&#39;)
</code></pre><ul>
<li>Write shell script to resize thumbnails with height larger than 400: <a href="https://gist.github.com/alanorth/131401dcd39d00e0ce12e1be3ed13256">https://gist.github.com/alanorth/131401dcd39d00e0ce12e1be3ed13256</a></li>
<li>Upload 707 CCAFS records to DSpace Test</li>
<li>A few miscellaneous fixes for XMLUI display niggles (spaces in item lists and link target <code>_black</code>): <a href="https://github.com/ilri/DSpace/pull/224">#224</a></li>
<li>Work on configuration changes for Phase 2 metadata migrations</li>
</ul>
<h2 id="2016-05-23">2016-05-23</h2>
<ul>
<li>Try to import the CCAFS Images and Videos to CGSpace but had some issues with LibreOffice and OpenRefine</li>
<li>LibreOffice excludes empty cells when it exports and all the fields shift over to the left and cause URLs to go to Subjects, etc.</li>
<li>Google Docs does this better, but somehow reorders the rows and when I paste the thumbnail/filename row in they don&rsquo;t match!</li>
<li>I will have to try later</li>
</ul>
<h2 id="2016-05-30">2016-05-30</h2>
<ul>
<li>Export CCAFS video and image records from DSpace Test using the migrate option (<code>-m</code>):</li>
</ul>
<pre tabindex="0"><code>$ mkdir ~/ccafs-images
$ /home/dspacetest.cgiar.org/bin/dspace export -t COLLECTION -i 10568/79355 -d ~/ccafs-images -n 0 -m

</code></pre><ul>
<li>But now we have double authors for &ldquo;CGIAR Research Program on Climate Change, Agriculture and Food Security&rdquo; in the authority</li>
<li>I&rsquo;m trying to do a Discovery index before messing with the authority index</li>
<li>Looks like we are missing the <code>index-authority</code> cron job, so who knows what&rsquo;s up with our authority index</li>
<li>Run system updates on DSpace Test, re-deploy code, and reboot the server</li>
<li>Clean up and import ~200 CTA records to CGSpace via CSV like:</li>
</ul>
<pre tabindex="0"><code>$ export JAVA_OPTS=&#34;-Xmx512m -Dfile.encoding=UTF-8&#34;

<li>Discovery indexing took a few hours for some reason, and after that I started the <code>index-authority</code> script</li>

<li>The <code>index-authority</code> script ran over night and was finished in the morning</li>

Experimenting with IFPRI OAI (we want to harvest their publications)
After reading the ContentDM documentation I found IFPRI&rsquo;s OAI endpoint: http://ebrary.ifpri.org/oai/oai.php
After reading the OAI documentation and testing with an OAI validator I found out how to get their publications
This is their publications set: http://ebrary.ifpri.org/oai/oai.php?verb=ListRecords&amp;from=2016-01-01&amp;set=p15738coll2&amp;metadataPrefix=oai_dc
You can see the others by using the OAI ListSets verb: http://ebrary.ifpri.org/oai/oai.php?verb=ListSets
Working on second phase of metadata migration, looks like this will work for moving CPWF-specific data in dc.identifier.fund to cg.identifier.cpwfproject and then the rest to dc.description.sponsorship

Working on second phase of metadata migration, looks like this will work for moving CPWF-specific data in dc.identifier.fund to cg.identifier.cpwfproject and then the rest to dc.description.sponsorship

<ul>
<li>Experimenting with IFPRI OAI (we want to harvest their publications)</li>
<li>After reading the <a href="https://www.oclc.org/support/services/contentdm/help/server-admin-help/oai-support.en.html">ContentDM documentation</a> I found IFPRI&rsquo;s OAI endpoint: <a href="http://ebrary.ifpri.org/oai/oai.php">http://ebrary.ifpri.org/oai/oai.php</a></li>
<li>After reading the <a href="https://www.openarchives.org/OAI/openarchivesprotocol.html">OAI documentation</a> and testing with an <a href="http://validator.oaipmh.com/">OAI validator</a> I found out how to get their publications</li>
<li>This is their publications set: <a href="http://ebrary.ifpri.org/oai/oai.php?verb=ListRecords&amp;from=2016-01-01&amp;set=p15738coll2&amp;metadataPrefix=oai_dc">http://ebrary.ifpri.org/oai/oai.php?verb=ListRecords&amp;from=2016-01-01&amp;set=p15738coll2&amp;metadataPrefix=oai_dc</a></li>
<li>You can see the others by using the OAI <code>ListSets</code> verb: <a href="http://ebrary.ifpri.org/oai/oai.php?verb=ListSets">http://ebrary.ifpri.org/oai/oai.php?verb=ListSets</a></li>
<li>Working on second phase of metadata migration, looks like this will work for moving CPWF-specific data in <code>dc.identifier.fund</code> to <code>cg.identifier.cpwfproject</code> and then the rest to <code>dc.description.sponsorship</code></li>
</ul>
<pre tabindex="0"><code>dspacetest=# update metadatavalue set metadata_field_id=130 where metadata_field_id=75 and (text_value like &#39;PN%&#39; or text_value like &#39;PHASE%&#39; or text_value = &#39;CBA&#39; or text_value = &#39;IA&#39;);
UPDATE 497
dspacetest=# update metadatavalue set metadata_field_id=29 where metadata_field_id=75;
UPDATE 14
</code></pre><ul>
<li>Fix a few minor miscellaneous issues in <code>dspace.cfg</code> (<a href="https://github.com/ilri/DSpace/pull/227">#227</a>)</li>
</ul>
<h2 id="2016-06-02">2016-06-02</h2>
<ul>
<li>Testing the configuration and theme changes for the upcoming metadata migration and I found some issues with <code>cg.coverage.admin-unit</code></li>
<li>Seems that the Browse configuration in <code>dspace.cfg</code> can&rsquo;t handle the &lsquo;-&rsquo; in the field name:</li>
</ul>
<pre tabindex="0"><code>webui.browse.index.12 = subregion:metadata:cg.coverage.admin-unit:text
</code></pre><ul>
<li>But actually, I think since DSpace 4 or 5 (we are 5.1) the Browse indexes come from Discovery (defined in discovery.xml) so this is really just a parsing error</li>
<li>I&rsquo;ve sent a message to the DSpace mailing list to ask about the Browse index definition</li>
<li>A user was having problems with submission and from the stacktrace it looks like a Sherpa/Romeo issue</li>
<li>I found a thread on the mailing list talking about it and there is bug report and a patch: <a href="https://jira.duraspace.org/browse/DS-2740">https://jira.duraspace.org/browse/DS-2740</a></li>
<li>The patch applies successfully on DSpace 5.1 so I will try it later</li>
</ul>
<h2 id="2016-06-03">2016-06-03</h2>
<ul>
<li>Investigating the CCAFS authority issue, I exported the metadata for the Videos collection</li>
<li>The top two authors are:</li>
</ul>
<pre tabindex="0"><code>CGIAR Research Program on Climate Change, Agriculture and Food Security::acd00765-02f1-4b5b-92fa-bfa3877229ce::500

<li>So the only difference is the &ldquo;confidence&rdquo;</li>
<li>Ok, well THAT is interesting:</li>
</ul>
<pre tabindex="0"><code>dspacetest=# select text_value, authority, confidence from metadatavalue where metadata_field_id=3 and text_value like &#39;%Orth, %&#39;;

<pre tabindex="0"><code>dspacetest=# select count(*) from metadatavalue where metadata_field_id=3 and text_value like &#39;CGIAR Research Program on Climate Change, Agriculture and Food Security&#39; and confidence = 500;

UPDATE 960
</code></pre><ul>
<li>And then re-indexing authority and Discovery&hellip;?</li>
<li>After Discovery reindex the CCAFS authors are all together in the Authors sidebar facet</li>
<li>The docs for the ORCiD and Authority stuff for DSpace 5 mention changing the browse indexes to use the Authority as well:</li>
</ul>
<pre tabindex="0"><code>webui.browse.index.2 = author:metadataAuthority:dc.contributor.author:authority
</code></pre><ul>
<li>That would only be for the &ldquo;Browse by&rdquo; function&hellip; so we&rsquo;ll have to see what effect that has later</li>
</ul>
<h2 id="2016-06-04">2016-06-04</h2>
<ul>
<li>Re-sync DSpace Test with CGSpace and perform test of metadata migration again</li>
<li>Run phase two of metadata migrations on CGSpace (see the <a href="https://gist.github.com/alanorth/1a730bec5ac9457a8fb0e3e72c98d09c">migration notes</a>)</li>
<li>Run all system updates and reboot CGSpace server</li>
</ul>
<h2 id="2016-06-07">2016-06-07</h2>
<ul>
<li>Figured out how to export a list of the unique values from a metadata field ordered by count:</li>
</ul>
<pre tabindex="0"><code>dspacetest=# \copy (select text_value, count(*) from metadatavalue where resource_type_id=2 and metadata_field_id=29 group by text_value order by count desc) to /tmp/sponsorship.csv with csv;
</code></pre><ul>
<li>
<p>Identified the next round of fields to migrate:</p>
<ul>
<li>dc.title.jtitle → dc.source</li>
<li>dc.crsubject.crpsubject → cg.contributor.crp</li>
<li>dc.contributor.affiliation → cg.contributor.affiliation</li>
<li>dc.Species → cg.species</li>
<li>dc.contributor.corporate → dc.contributor</li>
<li>dc.identifier.url → cg.identifier.url</li>
<li>dc.identifier.doi → cg.identifier.doi</li>
<li>dc.identifier.googleurl → cg.identifier.googleurl</li>
<li>dc.identifier.dataurl → cg.identifier.dataurl</li>
</ul>
</li>
<li>
<p>Discuss pulling data from IFPRI&rsquo;s ContentDM with Ryan Miller</p>
</li>
<li>
<p>Looks like OAI is kinda obtuse for this, and if we use ContentDM&rsquo;s API we&rsquo;ll be able to access their internal field names (rather than trying to figure out how they stuffed them into various, repeated Dublin Core fields)</p>
</li>
</ul>
<h2 id="2016-06-08">2016-06-08</h2>
<ul>
<li>Discuss controlled vocabularies for ~28 fields</li>
<li>Looks like this is all we need: <a href="https://wiki.lyrasis.org/display/DSDOC5x/Submission+User+Interface#SubmissionUserInterface-ConfiguringControlledVocabularies">https://wiki.lyrasis.org/display/DSDOC5x/Submission+User+Interface#SubmissionUserInterface-ConfiguringControlledVocabularies</a></li>
<li>I wrote an XPath expression to extract the ILRI subjects from <code>input-forms.xml</code> (from the xmlstarlet package):</li>
</ul>
<pre tabindex="0"><code>$ xml sel -t -m &#39;//value-pairs[@value-pairs-name=&#34;ilrisubject&#34;]/pair/displayed-value/text()&#39; -c &#39;.&#39; -n dspace/config/input-forms.xml
</code></pre><ul>
<li>Write to Atmire about the use of <code>atmire.orcid.id</code> to see if we can change it</li>
<li>Seems to be a virtual field that is queried from the authority cache&hellip; hmm</li>
<li>In other news, I found out that the About page that we haven&rsquo;t been using lives in <code>dspace/config/about.xml</code>, so now we can update the text</li>
<li>File bug about <code>closed=&quot;true&quot;</code> attribute of controlled vocabularies not working: <a href="https://jira.duraspace.org/browse/DS-3238">https://jira.duraspace.org/browse/DS-3238</a></li>
</ul>
<h2 id="2016-06-09">2016-06-09</h2>
<ul>
<li>Atmire explained that the <code>atmire.orcid.id</code> field doesn&rsquo;t exist in the schema, as it actually comes from the authority cache during XMLUI run time</li>
<li>This means we don&rsquo;t see it when harvesting via OAI or REST, for example</li>
<li>They opened a feature ticket on the DSpace tracker to ask for support of this: <a href="https://jira.duraspace.org/browse/DS-3239">https://jira.duraspace.org/browse/DS-3239</a></li>

<ul>
<li>Investigating authority confidences</li>
<li>It looks like the values are documented in <code>Choices.java</code></li>
<li>Experiment with setting all 960 CCAFS author values to be 500:</li>
</ul>
<pre tabindex="0"><code>dspacetest=# SELECT authority, confidence FROM metadatavalue WHERE resource_type_id=2 AND metadata_field_id=3 AND text_value = &#39;CGIAR Research Program on Climate Change, Agriculture and Food Security&#39;;
dspacetest=# UPDATE metadatavalue set confidence = 500 where resource_type_id=2 AND metadata_field_id=3 AND text_value = &#39;CGIAR Research Program on Climate Change, Agriculture and Food Security&#39;;
UPDATE 960
</code></pre><ul>
<li>After the database edit, I did a full Discovery re-index</li>
<li>And now there are exactly 960 items in the authors facet for &lsquo;CGIAR Research Program on Climate Change, Agriculture and Food Security&rsquo;</li>
<li>Now I ran the same on CGSpace</li>
<li>Merge controlled vocabulary functionality for animal breeds to <code>5_x-prod</code> (<a href="https://github.com/ilri/DSpace/pull/236">#236</a>)</li>
<li>Write python script to update metadata values in batch via PostgreSQL: <a href="https://gist.github.com/alanorth/df92cbfb54d762ba21b28f7cd83b6897">fix-metadata-values.py</a></li>
<li>We need to use this to correct some pretty ugly values in fields like <code>dc.description.sponsorship</code></li>
<li>Merge item display tweaks from earlier this week (<a href="https://github.com/ilri/DSpace/pull/231">#231</a>)</li>
<li>Merge controlled vocabulary functionality for subregions (<a href="https://github.com/ilri/DSpace/pull/238">#238</a>)</li>

</li>
<li>
<p>The final list of fields to migrate in the third phase of metadata migrations is:</p>

Add dc.description.sponsorship to Discovery sidebar facets and make investors clickable in item view (#232)
I think this query should find and replace all authors that have &ldquo;,&rdquo; at the end of their names:
dspacetest=# update metadatavalue set text_value = regexp_replace(text_value, &#39;(^.&#43;?),$&#39;, &#39;\1&#39;) where metadata_field_id=3 and resource_type_id=2 and text_value ~ &#39;^.&#43;?,$&#39;;
UPDATE 95
dspacetest=# select text_value from metadatavalue where metadata_field_id=3 and resource_type_id=2 and text_value ~ &#39;^.&#43;?,$&#39;;
text_value
------------
(0 rows)
In this case the select query was showing 95 results before the update

<li>If I unzip the original zip from CIAT on Windows, re-zip it with 7zip on Windows, and then unzip it on Linux directly, the file names seem to be proper UTF-8</li>

<li>Seems that the latter method causes a null pointer exception, so I will just have to use the former method</li>
<li>In the end I was able to import the files after unzipping them ONLY on Linux

<li>After that we need to take the top ~300 and make a controlled vocabulary for it</li>
<li>I dumped a list of the top 300 affiliations from the database, sorted it alphabetically in OpenRefine, and created a controlled vocabulary for it (<a href="https://github.com/ilri/DSpace/pull/267">#267</a>)</li>

<li>Peter asked about adding title search to Discovery</li>
<li>The index was already defined, so I just added it to the search filters</li>
<li>It works but CGSpace apparently uses <code>OR</code> for search terms, which makes the search results basically useless</li>
<li>I need to read the docs and ask on the mailing list to see if we can tweak that</li>
<li>Generate a new list of sponsors from the database for Peter Ballantyne so we can clean them up and update the controlled vocabulary</li>

Testing adding ORCIDs to a CSV file for a single item to see if the author orders get messed up
Need to test the following scenarios to see how author order is affected:
ORCIDs only
ORCIDs plus normal authors

<p><img src="/cgspace-notes/2016/10/cmyk-vs-srgb.jpg" alt="CMYK vs sRGB colors"></p>
<ul>
<li>Turns out the first PDF was exported from InDesign using CMYK and the second one was using sRGB</li>
<li>Run all system updates on DSpace Test and reboot it</li>
</ul>
<h2 id="2016-10-08">2016-10-08</h2>
<ul>
<li>Re-deploy CGSpace with latest changes from late September and early October</li>
<li>Run fixes for ILRI subjects and delete blank metadata values:</li>
</ul>
<pre tabindex="0"><code>dspace=# delete from metadatavalue where resource_type_id=2 and text_value=&#39;&#39;;
DELETE 11
</code></pre><ul>
<li>Run all system updates and reboot CGSpace</li>
<li>Delete ten gigs of old 2015 Tomcat logs that never got rotated (WTF?):</li>
</ul>
<pre tabindex="0"><code>root@linode01:~# ls -lh /var/log/tomcat7/localhost_access_log.2015* | wc -l
47
</code></pre><ul>
<li>Delete 2GB <code>cron-filter-media.log</code> file, as it is just a log from a cron job and it doesn&rsquo;t get rotated like normal log files (almost a year now maybe)</li>
</ul>
<h2 id="2016-10-14">2016-10-14</h2>
<ul>
<li>Run all system updates on DSpace Test and reboot server</li>
<li>Looking into some issues with Discovery filters in Atmire&rsquo;s content and usage analysis module after adjusting the filter class</li>
<li>Looks like changing the filters from <code>configuration.DiscoverySearchFilterFacet</code> to <code>configuration.DiscoverySearchFilter</code> breaks them in Atmire CUA module</li>
</ul>
<h2 id="2016-10-17">2016-10-17</h2>
<ul>
<li>A bit more cleanup on the CCAFS authors, and run the corrections on DSpace Test:</li>
</ul>
<pre tabindex="0"><code>$ ./fix-metadata-values.py -i ccafs-authors-oct-16.csv -f dc.contributor.author -t &#39;correct name&#39; -m 3 -d dspace -u dspace -p fuuu
</code></pre><ul>
<li>One observation is that there are still some old versions of names in the author lookup because authors appear in other communities (as we only corrected authors from CCAFS for this round)</li>
</ul>
<h2 id="2016-10-18">2016-10-18</h2>
<ul>
<li>Start working on DSpace 5.5 porting work again:</li>
</ul>
<pre tabindex="0"><code>$ git checkout -b 5_x-55 5_x-prod
$ git rebase -i dspace-5.5
</code></pre><ul>
<li>Have to fix about ten merge conflicts, mostly in the SCSS for the CGIAR theme</li>
<li>Skip 1e34751b8cf17021f45d4cf2b9a5800c93fb4cb2 in lieu of upstream&rsquo;s 55e623d1c2b8b7b1fa45db6728e172e06bfa8598 (fixes X-Forwarded-For header) because I had made the same fix myself and it&rsquo;s better to use the upstream one</li>
<li>I notice this rebase gets rid of GitHub merge commits&hellip; which actually might be fine because merges are fucking annoying to deal with when remote people merge without pulling and rebasing their branch first</li>
<li>Finished up applying the 5.5 sitemap changes to all themes</li>
<li>Merge the <code>discovery.xml</code> cleanups (<a href="https://github.com/ilri/DSpace/pull/278">#278</a>)</li>
<li>Merge some minor edits to the distribution license (<a href="https://github.com/ilri/DSpace/pull/285">#285</a>)</li>
</ul>
<h2 id="2016-10-19">2016-10-19</h2>
<ul>
<li>When we move to DSpace 5.5 we should also cherry pick some patches from 5.6 branch:
<ul>
<li><a href="https://jira.duraspace.org/browse/DS-3246">memory cleanup</a>: 9f0f5940e7921765c6a22e85337331656b18a403</li>
<li>sql injection: c6fda557f731dbc200d7d58b8b61563f86fe6d06</li>
<li>pdfbox security issue: b5330b78153b2052ed3dc2fd65917ccdbfcc0439</li>
</ul>
</li>
</ul>
<h2 id="2016-10-20">2016-10-20</h2>
<ul>
<li>Run CCAFS author corrections on CGSpace</li>
<li>Discovery reindexing took forever and kinda caused CGSpace to crash, so I ran all system updates and rebooted the server</li>
</ul>
<h2 id="2016-10-25">2016-10-25</h2>
<ul>
<li>Move the LIVES community from the top level to the ILRI projects community</li>

<li>Start testing some things for DSpace 5.5, like command line metadata import, PDF media filter, and Atmire CUA</li>
<li>Start looking at batch fixing of &ldquo;old&rdquo; ILRI website links without www or https, for example:</li>
</ul>
<pre tabindex="0"><code>dspace=# select * from metadatavalue where resource_type_id=2 and text_value like &#39;http://ilri.org%&#39;;

<li>Also CCAFS has HTTPS and their links should use it where possible:</li>
</ul>
<pre tabindex="0"><code>dspace=# select * from metadatavalue where resource_type_id=2 and text_value like &#39;http://ccafs.cgiar.org%&#39;;
</code></pre><ul>
<li>And this will find community and collection HTML text that is using the old style PNG/JPG icons for RSS and email (we should be using Font Awesome icons instead):</li>
</ul>
<pre tabindex="0"><code>dspace=# select text_value from metadatavalue where resource_type_id in (3,4) and text_value like &#39;%Iconrss2.png%&#39;;

<li>Turns out there are shit tons of varieties of this, like with http, https, www, separate <code>&lt;/img&gt;</code> tags, alignments, etc</li>
<li>Had to find all variations and replace them individually:</li>

<li>Getting rid of these reduces the number of network requests each client makes on community/collection pages, and makes use of Font Awesome icons (which they are already loading anyways!)</li>
<li>And now that I start looking, I want to fix a bunch of links to popular sites that should be using HTTPS, like Twitter, Facebook, Google, Feed Burner, DOI, etc</li>
<li>I should look to see if any of those domains is sending an HTTP 301 or setting HSTS headers to their HTTPS domains, then just replace them</li>

CGSpace was down for five hours in the morning while I was sleeping

<li>Looks like we have ~5GB of memory used by caches on the test server (after OS and JVM heap!), so we might as well bump up the buffers for Postgres</li>
<li>The docs say a good starting point for a dedicated server is 25% of the system RAM, and our server isn&rsquo;t dedicated (also runs Solr, which can benefit from OS cache) so let&rsquo;s try 1024MB</li>

<li>Checking in on CGSpace postgres stats again, looks like the <code>shared_buffers</code> change from a few days ago really made a big impact:</li>

<ul>
<li>Looking at logs, it seems we need to evaluate which logs we keep and for how long</li>
<li>Basically the only ones we <em>need</em> are <code>dspace.log</code> because those are used for legacy statistics (need to keep for 1 month)</li>
<li>Other logs will be an issue because they don&rsquo;t have date stamps</li>
<li>I will add date stamps to the logs we&rsquo;re storing from the tomcat7 user&rsquo;s cron jobs at least, using: <code>$(date --iso-8601)</code></li>
<li>Would probably be better to make custom logrotate files for them in the future</li>
<li>Clean up some unneeded log files from 2014 (they weren&rsquo;t large, just don&rsquo;t need them)</li>
<li>So basically, new cron jobs for logs should look something like this:</li>
<li>Find any file named <code>*.log*</code> that isn&rsquo;t <code>dspace.log*</code>, isn&rsquo;t already zipped, and is older than one day, and zip it:</li>
</ul>
<pre tabindex="0"><code># find /home/dspacetest.cgiar.org/log -regextype posix-extended -iregex &#34;.*\.log.*&#34; ! -iregex &#34;.*dspace\.log.*&#34; ! -iregex &#34;.*\.(gz|lrz|lzo|xz)&#34; ! -newermt &#34;Yesterday&#34; -exec schedtool -B -e ionice -c2 -n7 xz {} \;
</code></pre><ul>
<li>Since there is <code>xzgrep</code> and <code>xzless</code> we can actually just zip them after one day, why not?!</li>
<li>We can keep the zipped ones for two weeks just in case we need to look for errors, etc, and delete them after that</li>
<li>I use <code>schedtool -B</code> and <code>ionice -c2 -n7</code> to set the CPU scheduling to <code>SCHED_BATCH</code> and the IO to best effort which should, in theory, impact important system processes like Tomcat and PostgreSQL less</li>
<li>When the tasks are running you can see that the policies do apply:</li>
</ul>
<pre tabindex="0"><code>$ schedtool $(ps aux | grep &#34;xz /home&#34; | grep -v grep | awk &#39;{print $2}&#39;) &amp;&amp; ionice -p $(ps aux | grep &#34;xz /home&#34; | grep -v grep | awk &#39;{print $2}&#39;)
PID 17049: PRIO 0, POLICY B: SCHED_BATCH , NICE 0, AFFINITY 0xf
best-effort: prio 7
</code></pre><ul>
<li>All in all this should free up a few gigs (we were at 9.3GB free when I started)</li>
<li>Next thing to look at is whether we need Tomcat&rsquo;s access logs</li>
<li>I just looked and it seems that we saved 10GB by zipping these logs</li>
<li>Some users pointed out issues with the &ldquo;most popular&rdquo; stats on a community or collection</li>
<li>This error appears in the logs when you try to view them:</li>

<li>After applying pull request <a href="https://github.com/ilri/DSpace/pull/291">#291</a> on DSpace Test I no longer see the error in the logs after the <code>UpdateSolrStorageReports</code> task runs</li>
<li>Also, I&rsquo;m toying with the idea of moving the <code>tomcat7</code> user&rsquo;s cron jobs to <code>/etc/cron.d</code> so we can manage them in Ansible</li>

<li>Start planning for server migration this weekend, letting users know</li>
<li>I am trying to figure out what the process is to <a href="http://handle.net/hnr_support.html">update the server&rsquo;s IP in the Handle system</a>, and emailing the hdladmin account bounces(!)</li>
<li>I will contact the Jane Euler directly as I know I&rsquo;ve corresponded with her in the past</li>
<li>She said that I should indeed just re-run the <code>[dspace]/bin/dspace make-handle-config</code> command and submit the new <code>sitebndl.zip</code> file to the CNRI website</li>
<li>Also I was troubleshooting some workflow issues from Bizuwork</li>
<li>I re-created the same scenario by adding a non-admin account and submitting an item, but I was able to successfully approve and commit it</li>
<li>So it turns out it&rsquo;s not a bug, it&rsquo;s just that Peter was added as a reviewer/admin AFTER the items were submitted</li>
<li>This is how DSpace works, and I need to ask if there is a way to override someone&rsquo;s submission, as the other reviewer seems to not be paying attention, or has perhaps taken the item from the task pool?</li>
<li>Run a batch edit to add &ldquo;RANGELANDS&rdquo; ILRI subject to all items containing the word &ldquo;RANGELANDS&rdquo; in their metadata for Peter Ballantyne</li>

I checked to see if the Solr sharding task that is supposed to run on January 1st had run and saw there was an error
I tested on DSpace Test as well and it doesn&rsquo;t work there either
I asked on the dspace-tech mailing list because it seems to be broken, and actually now I&rsquo;m not sure if we&rsquo;ve ever had the sharding task run successfully over all these years

<li>A user wrote to tell me that the new display of an item&rsquo;s mappings had a crazy bug for at least one item: <a href="https://cgspace.cgiar.org/handle/10568/78596">https://cgspace.cgiar.org/handle/10568/78596</a></li>

<h2 id="2017-01-10">2017-01-10</h2>
<ul>
<li>I tried to clean up the duplicate mappings by exporting the item&rsquo;s metadata to CSV, editing, and re-importing, but DSpace said &ldquo;no changes were detected&rdquo;</li>
<li>I&rsquo;ve asked on the dspace-tech mailing list to see if anyone can help</li>
<li>I found an old post on the mailing list discussing a similar issue, and listing some SQL commands that might help</li>
<li>For example, this shows 186 mappings for the item, the first three of which are real:</li>
</ul>
<pre tabindex="0"><code>dspace=# select * from collection2item where item_id = &#39;80596&#39;;
</code></pre><ul>
<li>Then I deleted the others:</li>
</ul>
<pre tabindex="0"><code>dspace=# delete from collection2item where item_id = &#39;80596&#39; and id not in (90792, 90806, 90807);
</code></pre><ul>
<li>And in the item view it now shows the correct mappings</li>
<li>I will have to ask the DSpace people if this is a valid approach</li>
<li>Finish looking at the Journal Title corrections of the top 500 Journal Titles so we can make a controlled vocabulary from it</li>

<li>The values are a bit dirty and outdated, since the file I had given to Abenet and Peter was from November</li>

<li>And the file names don&rsquo;t really matter either, as long as the SAF Builder tool can read them—after that DSpace renames them with a hash in the assetstore</li>
<li>Seems like the only ones I should replace are the <code>'</code> apostrophe characters, as <code>%27</code>:</li>
</ul>

<li>Many of the PDFs are 20, 30, 40, 50+ MB, which makes a total of 4GB</li>

<li>We also need to rename some of the CCAFS Phase I flagships:
<ul>
<li>CLIMATE-SMART AGRICULTURAL PRACTICES → CLIMATE-SMART TECHNOLOGIES AND PRACTICES</li>
<li>CLIMATE RISK MANAGEMENT → CLIMATE SERVICES AND SAFETY NETS</li>
<li>LOW EMISSIONS AGRICULTURE → LOW EMISSIONS DEVELOPMENT</li>
<li>POLICIES AND INSTITUTIONS → PRIORITIES AND POLICIES FOR CSA</li>
</ul>
</li>
<li>The climate risk management one doesn&rsquo;t exist, so I will have to ask Magdalena if they want me to add it to the input forms</li>
<li>Start testing some nearly 500 author corrections that CCAFS sent me:</li>
</ul>

<li>More work on CCAFS Phase II stuff</li>
<li>Looks like simply adding a new metadata field to <code>dspace/config/registries/cgiar-types.xml</code> and restarting DSpace causes the field to get added to the rregistry</li>
<li>It requires a restart but at least it allows you to manage the registry programmatically</li>
<li>It&rsquo;s not a very good way to manage the registry, though, as removing one there doesn&rsquo;t cause it to be removed from the registry, and we always restore from database backups so there would never be a scenario when we needed these to be created</li>
<li>Testing some corrections on CCAFS Phase II flagships (<code>cg.subject.ccafs</code>):</li>

<ul>
<li>Add <code>SCALING</code> to ILRI subjects (<a href="https://github.com/ilri/DSpace/pull/304">#304</a>), as Sisay&rsquo;s attempts were all sloppy</li>
<li>Cherry pick some patches from the DSpace 5.7 branch:
<ul>
<li>DS-3363 CSV import error says &ldquo;row&rdquo;, means &ldquo;column&rdquo;: f7b6c83e991db099003ee4e28ca33d3c7bab48c0</li>
<li>DS-3479 avoid adding empty metadata values during import: 329f3b48a6de7fad074d825fd12118f7e181e151</li>
<li>[DS-3456] 5x Clarify command line options for statisics import/export tools (#1623): 567ec083c8a94eb2bcc1189816eb4f767745b278</li>
<li>[DS-3458]5x Allow Shard Process to Append to an existing repo: 3c8ecb5d1fd69a1dcfee01feed259e80abbb7749</li>

<li>We are using only ~8GB of RAM for applications, and 16GB for caches!</li>
<li>The Linode machine we&rsquo;re on has 24GB of RAM but only because that&rsquo;s the only instance that had enough disk space for us (384GB)&hellip;</li>
<li>We should probably look into Google Compute Engine or Digital Ocean where we can get more storage without having to follow a linear increase in instance pricing for CPU/memory as well</li>
<li>Especially because we only use 2 out of 8 CPUs basically:</li>

<li>It seems this might have only been a temporary problem, as both Python 3.5.2 and 3.6.0 are able to print the problematic string &ldquo;Entwicklung &amp; Ländlicher Raum&rdquo; without the <code>encode()</code> call, but print it as a bytes when it <em>is</em> used:</li>

Run the 279 CIAT author corrections on CGSpace
2017-03-02
Skype with Michael and Peter, discussing moving the CGIAR Library to CGSpace
CGIAR people possibly open to moving content, redirecting library.cgiar.org to CGSpace and letting CGSpace resolve their handles
They might come in at the top level in one &ldquo;CGIAR System&rdquo; community, or with several communities
I need to spend a bit of time looking at the multiple handle support in DSpace and see if new content can be minted in both handles, or just one?
Need to send Peter and Michael some notes about this in a few days
Also, need to consider talking to Atmire about hiring them to bring ORCiD metadata to REST / OAI
Filed an issue on DSpace issue tracker for the filter-media bug that causes it to process JPGs even when limiting to the PDF thumbnail plugin: DS-3516
Discovered that the ImageMagic filter-media plugin creates JPG thumbnails with the CMYK colorspace when the source PDF is using CMYK
Interestingly, it seems DSpace 4.x&rsquo;s thumbnails were sRGB, but forcing regeneration using DSpace 5.x&rsquo;s ImageMagick plugin creates CMYK JPGs if the source PDF was CMYK (see 10568/51999):

<li>This reads the input file, applies the CMYK profile, applies the RGB profile, then writes the file</li>
<li>Note that you should set the first profile immediately after the input file</li>
<li>Also, it is better to use profiles than setting <code>-colorspace</code></li>
<li>This is a great resource describing the color stuff: <a href="http://www.imagemagick.org/Usage/formats/#profiles">http://www.imagemagick.org/Usage/formats/#profiles</a></li>
<li>Somehow we need to detect the color system being used by the input file and handle each case differently (with profiles)</li>
<li>This is trivial with <code>identify</code> (even by the <a href="http://im4java.sourceforge.net/api/org/im4java/core/IMOps.html#identify">Java ImageMagick API</a>):</li>

<ul>
<li>Spent more time looking at the ImageMagick CMYK issue</li>
<li>The <code>default_cmyk.icc</code> and <code>default_rgb.icc</code> files are both part of the Ghostscript GPL distribution, but according to DSpace&rsquo;s <code>LICENSES_THIRD_PARTY</code> file, DSpace doesn&rsquo;t allow distribution of dependencies that are licensed solely under the GPL</li>
<li>So this issue is kinda pointless now, as the ICC profiles are absolutely necessary to make a meaningful CMYK→sRGB conversion</li>

<li>Look into helping developers from landportal.info with a query for items related to LAND on the REST API</li>
<li>They want something like the items that are returned by the general &ldquo;LAND&rdquo; query in the search interface, but we cannot do that</li>
<li>We can only return specific results for metadata fields, like:</li>
</ul>
<pre tabindex="0"><code>$ curl -s -H &#34;accept: application/json&#34; -H &#34;Content-Type: application/json&#34; -X POST &#34;https://dspacetest.cgiar.org/rest/items/find-by-metadata-field&#34; -d &#39;{&#34;key&#34;: &#34;cg.subject.ilri&#34;,&#34;value&#34;: &#34;LAND REFORM&#34;, &#34;language&#34;: null}&#39; | json_pp

<li>But there are hundreds of combinations of fields and values (like <code>dc.subject</code> and all the center subjects), and we can&rsquo;t use wildcards in REST!</li>
<li>Reading about enabling multiple handle prefixes in DSpace</li>
<li>There is a mailing list thread from 2011 about it: <a href="http://dspace.2283337.n4.nabble.com/Multiple-handle-prefixes-merged-DSpace-instances-td3427192.html">http://dspace.2283337.n4.nabble.com/Multiple-handle-prefixes-merged-DSpace-instances-td3427192.html</a></li>
<li>And a comment from Atmire&rsquo;s Bram about it on the DSpace wiki: <a href="https://wiki.lyrasis.org/display/DSDOC5x/Installing+DSpace?focusedCommentId=78163296#comment-78163296">https://wiki.lyrasis.org/display/DSDOC5x/Installing+DSpace?focusedCommentId=78163296#comment-78163296</a></li>
<li>Bram mentions an undocumented configuration option <code>handle.plugin.checknameauthority</code>, but I noticed another one in <code>dspace.cfg</code>:</li>
</ul>
<pre tabindex="0"><code># List any additional prefixes that need to be managed by this handle server
# (as for examle handle prefix coming from old dspace repository merged in
# that repository)
# handle.additional.prefixes = prefix1[, prefix2]
</code></pre><ul>
<li>Because of this I noticed that our Handle server&rsquo;s <code>config.dct</code> was potentially misconfigured!</li>
<li>We had some default values still present:</li>
</ul>
<pre tabindex="0"><code>&#34;300:0.NA/YOUR_NAMING_AUTHORITY&#34;

<li>I&rsquo;ve changed them to the following and restarted the handle server:</li>
</ul>
<pre tabindex="0"><code>&#34;300:0.NA/10568&#34;

<li>In looking at all the configs I just noticed that we are not providing a DOI in the Google-specific metadata crosswalk</li>
<li>From <code>dspace/config/crosswalks/google-metadata.properties</code>:</li>
</ul>
<pre tabindex="0"><code>google.citation_doi = cg.identifier.doi

<li>This works, and makes DSpace output the following metadata on the item view page:</li>

<li>Someone on the mailing list said that <code>handle.plugin.checknameauthority</code> should be false if we&rsquo;re using multiple handle prefixes</li>
</ul>
<h2 id="2017-03-07">2017-03-07</h2>
<ul>
<li>I set up a top-level community as a test for the CGIAR Library and imported one item with the the 10947 handle prefix</li>
<li>When testing the Handle resolver locally it shows the item to be on the local repository</li>
<li>So this seems to work, with the following caveats:
<ul>
<li>New items will have the default handle</li>
<li>Communities and collections will have the default handle</li>
<li>Only items imported manually can have the other handles</li>
</ul>
</li>
<li>I need to talk to Michael and Peter to share the news, and discuss the structure of their community(s) and try some actual test data</li>
<li>We&rsquo;ll need to do some data cleaning to make sure they are using the same fields we are, like <code>dc.type</code> and <code>cg.identifier.status</code></li>
<li>Another thing is that the import process creates new <code>dc.date.accessioned</code> and <code>dc.date.available</code> fields, so we end up with duplicates (is it important to preserve the originals for these?)</li>
<li>Report DS-3520 issue to Atmire</li>

<li>After reading the <a href="https://wiki.lyrasis.org/display/cmtygp/DCAT+Meeting+April+2017">notes for DCAT April 2017</a> I am testing some new settings for PostgreSQL on DSpace Test:
<ul>
<li><code>db.maxconnections</code> 30→70 (the default PostgreSQL config allows 100 connections, so DSpace&rsquo;s default of 30 is quite low)</li>
<li><code>db.maxwait</code> 5000→10000</li>
<li><code>db.maxidle</code> 8→20 (DSpace default is -1, unlimited, but we had set it to 8 earlier)</li>
</ul>

<li>I need to look at the Munin graphs after a few days to see if the load has changed</li>
<li>Run system updates on DSpace Test and reboot the server</li>
<li>Discussing harvesting CIFOR&rsquo;s DSpace via OAI</li>
<li>Sisay added their OAI as a source to a new collection, but using the Simple Dublin Core method, so many fields are unqualified and duplicated</li>
<li>Looking at the <a href="https://wiki.lyrasis.org/display/DSDOC5x/XMLUI+Configuration+and+Customization">documentation</a> it seems that we probably want to be using DSpace Intermediate Metadata</li>

<li>Remove James from Linode access</li>
<li>Look into having CIFOR use a sub prefix of 10568 like 10568.01</li>
<li>Handle.net calls this <a href="https://www.handle.net/faq.html#4">&ldquo;derived prefixes&rdquo;</a> and it seems this would work with DSpace if we wanted to go that route</li>
<li>CIFOR is starting to test aligning their metadata more with CGSpace/CG core</li>
<li>They shared a <a href="https://data.cifor.org/dspace/xmlui/handle/11463/947?show=full">test item</a> which is using <code>cg.coverage.country</code>, <code>cg.subject.cifor</code>, <code>dc.subject</code>, and <code>dc.date.issued</code></li>
<li>Looking at their OAI I&rsquo;m not sure it has updated as I don&rsquo;t see the new fields: <a href="https://data.cifor.org/dspace/oai/request?verb=ListRecords&amp;resumptionToken=oai_dc///col_11463_6/900">https://data.cifor.org/dspace/oai/request?verb=ListRecords&amp;resumptionToken=oai_dc///col_11463_6/900</a></li>
<li>Maybe they need to make sure they are running the OAI cache refresh cron job, or maybe OAI doesn&rsquo;t export these?</li>
<li>I added <code>cg.subject.cifor</code> to the metadata registry and I&rsquo;m waiting for the harvester to re-harvest to see if it picks up more data now</li>
<li>Another possiblity is that we could use a cross walk&hellip; but I&rsquo;ve never done it.</li>
</ul>
<h2 id="2017-04-11">2017-04-11</h2>
<ul>
<li>Looking at the item from CIFOR it hasn&rsquo;t been updated yet, maybe they aren&rsquo;t running the cron job</li>

<h2 id="2017-04-12">2017-04-12</h2>
<ul>
<li>CIFOR says they have cleaned their OAI cache and that the cron job for OAI import is enabled</li>
<li>Now I see updated fields, like <code>dc.date.issued</code> but none from the CG or CIFOR namespaces</li>
<li>Also, DSpace Test hasn&rsquo;t re-harvested this item yet, so I will wait one more day before forcing a re-harvest</li>
<li>Looking at CIFOR&rsquo;s OAI using different metadata formats, like qualified Dublin Core and DSpace Intermediate Metadata:

</ul>
</li>
<li>Looking at one of CGSpace&rsquo;s items in OAI it doesn&rsquo;t seem that metadata fields other than those in the DC schema are exported:

</ul>
</li>
<li>Side note: WTF, I just saw an item on CGSpace&rsquo;s OAI that is using <code>dc.cplace.country</code> and <code>dc.rplace.region</code>, which we stopped using in 2016 after the metadata migrations:</li>
</ul>
<p><img src="/cgspace-notes/2017/04/cplace.png" alt="stale metadata in OAI"></p>

<li>The particular item is <a href="http://hdl.handle.net/10568/6">10568/6</a> and, for what it&rsquo;s worth, the stale metadata only appears in the OAI view:

</ul>
</li>
<li>I don&rsquo;t see these fields anywhere in our source code or the database&rsquo;s metadata registry, so maybe it&rsquo;s just a cache issue</li>
<li>I will have to check the OAI cron scripts on DSpace Test, and then run them on CGSpace</li>
<li>Running <code>dspace oai import</code> and <code>dspace oai clean-cache</code> have zero effect, but this seems to rebuild the cache from scratch:</li>

<li>I don&rsquo;t know why there were no updates detected, so I will reset and reimport the collection</li>
<li>Usman has set up a custom crosswalk called <code>dimcg</code> that now shows CG and CIFOR metadata namespaces, but we can&rsquo;t use it because DSpace can only harvest DIM by default (from the harvesting user interface)</li>

<li>DSpace committers reviewed my patch for DS-3516 and proposed a simpler idea involving incorrect use of <code>SelfRegisteredInputFormats</code></li>

<li>I discovered that we can override metadata formats in OAI by creating a new &ldquo;context&rdquo;: <a href="https://wiki.lyrasis.org/display/DSDOC5x/OAI+2.0+Server">https://wiki.lyrasis.org/display/DSDOC5x/OAI+2.0+Server</a></li>
<li>This allows us to have, say a default &ldquo;request&rdquo; context and a &ldquo;cgiar&rdquo; context, both of which implement the DSpace Intermediate Metadata formats, but have the later use a overridden version that exposes CG metadata</li>

<ul>
<li>Sync DSpace Test with database and assetstore from CGSpace</li>
<li>Re-deploy DSpace Test with Atmire&rsquo;s CUA patch for workflow statistics, run system updates, and restart the server</li>
<li>Now I can see the workflow statistics and am able to select users, but everything returns 0 items</li>

<li>Discovered that CGSpace has ~700 items that are missing the <code>cg.identifier.status</code> field</li>
<li>Need to perhaps try using the &ldquo;required metadata&rdquo; curation task to find fields missing these items:</li>
</ul>
<pre tabindex="0"><code>$ [dspace]/bin/dspace curate -t requiredmetadata -i 10568/1 -r - &gt; /tmp/curation.out
</code></pre><ul>
<li>It seems the curation task dies when it finds an item which has missing metadata</li>
</ul>
<h2 id="2017-05-06">2017-05-06</h2>
<ul>
<li>Add &ldquo;Blog Post&rdquo; to <code>dc.type</code></li>
<li>Create ticket on Atmire tracker to ask about commissioning them to develop the feature to expose ORCID via REST/OAI: <a href="https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=510">https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=510</a></li>
<li>According to the <a href="https://wiki.lyrasis.org/display/DSDOC5x/Curation+System">DSpace curation docs</a> the fact that the <code>requiredmetadata</code> curation task stops when it finds a missing metadata field is by design</li>
</ul>
<h2 id="2017-05-07">2017-05-07</h2>
<ul>
<li>Testing one replacement for CCAFS Flagships (<code>cg.subject.ccafs</code>), first changed in the submission forms, and then in the database:</li>
</ul>
<pre tabindex="0"><code>$ ./fix-metadata-values.py -i ccafs-flagships-may7.csv -f cg.subject.ccafs -t correct -m 210 -d dspace -u dspace -p fuuu
</code></pre><ul>
<li>Also, CCAFS wants to re-order their flagships to prioritize the Phase II ones</li>
<li>Waiting for feedback from CCAFS, then I can merge <a href="https://github.com/ilri/DSpace/pull/320">#320</a></li>
</ul>
<h2 id="2017-05-08">2017-05-08</h2>
<ul>
<li>Start working on CGIAR Library migration</li>
<li>We decided to use AIP export to preserve the hierarchies and handles of communities and collections</li>
<li>When ingesting some collections I was getting <code>java.lang.OutOfMemoryError: GC overhead limit exceeded</code>, which can be solved by disabling the GC timeout with <code>-XX:-UseGCOverheadLimit</code></li>
<li>Other times I was getting an error about heap space, so I kept bumping the RAM allocation by 512MB each time (up to 4096m!) it crashed</li>
<li>This leads to tens of thousands of abandoned files in the assetstore, which need to be cleaned up using <code>dspace cleanup -v</code>, or else you&rsquo;ll run out of disk space</li>
<li>In the end I realized it&rsquo;s better to use submission mode (<code>-s</code>) to ingest the community object as a single AIP without its children, followed by each of the collections:</li>
</ul>
<pre tabindex="0"><code>$ export JAVA_OPTS=&#34;-Dfile.encoding=UTF-8 -Xmx2048m -XX:-UseGCOverheadLimit&#34;
$ [dspace]/bin/dspace packager -s -o ignoreHandle=false -t AIP -e some@user.com -p 10568/87775 /home/aorth/10947-1/10947-1.zip
$ for collection in /home/aorth/10947-1/COLLECTION@10947-*; do [dspace]/bin/dspace packager -s -o ignoreHandle=false -t AIP -e some@user.com -p 10947/1 $collection; done
$ for item in /home/aorth/10947-1/ITEM@10947-*; do [dspace]/bin/dspace packager -r -f -u -t AIP -e some@user.com $item; done
</code></pre><ul>
<li>Note that in submission mode DSpace ignores the handle specified in <code>mets.xml</code> in the zip file, so you need to turn that off with <code>-o ignoreHandle=false</code></li>
<li>The <code>-u</code> option supresses prompts, to allow the process to run without user input</li>
<li>Give feedback to CIFOR about their data quality:
<ul>
<li>Suggestion: uppercase dc.subject, cg.coverage.region, and cg.coverage.subregion in your crosswalk so they match CGSpace and therefore can be faceted / reported on easier</li>
<li>Suggestion: use CGSpace&rsquo;s CRP names (cg.contributor.crp), see: dspace/config/input-forms.xml</li>
<li>Suggestion: clean up duplicates and errors in funders, perhaps use a controlled vocabulary like ours, see: dspace/config/controlled-vocabularies/dc-description-sponsorship.xml</li>
<li>Suggestion: use dc.type &ldquo;Blog Post&rdquo; instead of &ldquo;Blog&rdquo; for your blog post items (we are also adding a &ldquo;Blog Post&rdquo; type to CGSpace soon)</li>
<li>Question: many of your items use dc.document.uri AND cg.identifier.url with the same text value?</li>
</ul>
</li>
<li>Help Marianne from WLE with an Open Search query to show the latest WLE CRP outputs: <a href="https://cgspace.cgiar.org/open-search/discover?query=crpsubject:WATER%2C+LAND+AND+ECOSYSTEMS&amp;sort_by=2&amp;order=DESC">https://cgspace.cgiar.org/open-search/discover?query=crpsubject:WATER%2C+LAND+AND+ECOSYSTEMS&amp;sort_by=2&amp;order=DESC</a></li>
<li>This uses the webui&rsquo;s item list sort options, see <code>webui.itemlist.sort-option</code> in <code>dspace.cfg</code></li>
<li>The equivalent Discovery search would be: <a href="https://cgspace.cgiar.org/discover?filtertype_1=crpsubject&amp;filter_relational_operator_1=equals&amp;filter_1=WATER%2C+LAND+AND+ECOSYSTEMS&amp;submit_apply_filter=&amp;query=&amp;rpp=10&amp;sort_by=dc.date.issued_dt&amp;order=desc">https://cgspace.cgiar.org/discover?filtertype_1=crpsubject&amp;filter_relational_operator_1=equals&amp;filter_1=WATER%2C+LAND+AND+ECOSYSTEMS&amp;submit_apply_filter=&amp;query=&amp;rpp=10&amp;sort_by=dc.date.issued_dt&amp;order=desc</a></li>

<h2 id="2017-05-09">2017-05-09</h2>
<ul>
<li>The CGIAR Library metadata has some blank metadata values, which leads to <code>|||</code> in the Discovery facets</li>
<li>Clean these up in the database using:</li>
</ul>
<pre tabindex="0"><code>dspace=# delete from metadatavalue where resource_type_id=2 and text_value=&#39;&#39;;
</code></pre><ul>
<li>I ended up running into issues during data cleaning and decided to wipe out the entire community and re-sync DSpace Test assetstore and database from CGSpace rather than waiting for the cleanup task to clean up</li>

<ul>
<li>After discussion with WLE and CGSpace content people, we decided to just add one metadata field for the WLE Research Themes</li>
<li>The <code>cg.identifier.wletheme</code> field will be used for both Phase I and Phase II Research Themes</li>
<li>Then we&rsquo;ll create a new sub-community for Phase II and create collections for the research themes there</li>
<li>The current &ldquo;Research Themes&rdquo; community will be renamed to &ldquo;WLE Phase I Research Themes&rdquo;</li>
<li>Tagged all items in the current Phase I collections with their appropriate themes</li>
<li>Create pull request to add Phase II research themes to the submission form: <a href="https://github.com/ilri/DSpace/pull/328">#328</a></li>
<li>Add <code>cg.subject.system</code> to CGSpace metadata registry, for subject from the upcoming CGIAR Library migration</li>
</ul>
<h2 id="2017-06-04">2017-06-04</h2>
<ul>
<li>After adding <code>cg.identifier.wletheme</code> to 1106 WLE items I can see the field on XMLUI but not in REST!</li>
<li>Strangely it happens on DSpace Test AND on CGSpace!</li>
<li>I tried to re-index Discovery but it didn&rsquo;t fix it</li>
<li>Run all system updates on DSpace Test and reboot the server</li>
<li>After rebooting the server (and therefore restarting Tomcat) the new metadata field is available</li>
<li>I&rsquo;ve sent a message to the dspace-tech mailing list to ask if this is a bug and whether I should file a Jira ticket</li>
</ul>
<h2 id="2016-06-05">2016-06-05</h2>
<ul>
<li>Rename WLE&rsquo;s &ldquo;Research Themes&rdquo; sub-community to &ldquo;WLE Phase I Research Themes&rdquo; on DSpace Test so Macaroni Bros can continue their testing</li>
<li>Macaroni Bros tested it and said it&rsquo;s fine, so I renamed it on CGSpace as well</li>
<li>Working on how to automate the extraction of the CIAT Book chapters, doing some magic in OpenRefine to extract page from–to from cg.identifier.url and dc.format.extent, respectively:
<ul>
<li>cg.identifier.url: <code>value.split(&quot;page=&quot;, &quot;&quot;)[1]</code></li>
<li>dc.format.extent: <code>value.replace(&quot;p. &quot;, &quot;&quot;).split(&quot;-&quot;)[1].toNumber() - value.replace(&quot;p. &quot;, &quot;&quot;).split(&quot;-&quot;)[0].toNumber()</code></li>
</ul>
</li>
<li>Finally, after some filtering to see which small outliers there were (based on dc.format.extent using &ldquo;p. 1-14&rdquo; vs &ldquo;29 p.&rdquo;), create a new column with last page number:
<ul>
<li><code>cells[&quot;dc.page.from&quot;].value.toNumber() + cells[&quot;dc.format.pages&quot;].value.toNumber()</code></li>
</ul>
</li>
<li>Then create a new, unique file name to be used in the output, based on a SHA1 of the dc.title and with a description:
<ul>
<li>dc.page.to: <code>value.split(&quot; &quot;)[0].replace(&quot;,&quot;,&quot;&quot;).toLowercase() + &quot;-&quot; + sha1(value).get(1,9) + &quot;.pdf__description:&quot; + cells[&quot;dc.type&quot;].value</code></li>
</ul>
</li>
<li>Start processing 769 records after filtering the following (there are another 159 records that have some other format, or for example they have their own PDF which I will process later), using a modified <code>generate-thumbnails.py</code> script to read certain fields and then pass to GhostScript:
<ul>
<li>cg.identifier.url: <code>value.contains(&quot;page=&quot;)</code></li>
<li>dc.format.extent: <code>or(value.contains(&quot;p. &quot;),value.contains(&quot; p.&quot;))</code></li>
<li>Command like: <code>$ gs -dNOPAUSE -dBATCH -dFirstPage=14 -dLastPage=27 -sDEVICE=pdfwrite -sOutputFile=beans.pdf -f 12605-1.pdf</code></li>
</ul>
</li>
<li>17 of the items have issues with incorrect page number ranges, and upon closer inspection they do not appear in the referenced PDF</li>
<li>I&rsquo;ve flagged them and proceeded without them (752 total) on DSpace Test:</li>
</ul>
<pre tabindex="0"><code>$ JAVA_OPTS=&#34;-Xmx1024m -Dfile.encoding=UTF-8&#34; [dspace]/bin/dspace import --add --eperson=aorth@mjanja.ch --collection=10568/93843 --source /home/aorth/src/CIAT-Books/SimpleArchiveFormat/ --mapfile=/tmp/ciat-books.map &amp;&gt; /tmp/ciat-books.log
</code></pre><ul>
<li>I went and did some basic sanity checks on the remaining items in the CIAT Book Chapters and decided they are mostly fine (except one duplicate and the flagged ones), so I imported them to DSpace Test too (162 items)</li>
<li>Total items in CIAT Book Chapters is 914, with the others being flagged for some reason, and we should send that back to CIAT</li>
<li>Restart Tomcat on CGSpace so that the <code>cg.identifier.wletheme</code> field is available on REST API for Macaroni Bros</li>
</ul>
<h2 id="2017-06-07">2017-06-07</h2>
<ul>
<li>Testing <a href="https://github.com/ilri/DSpace/pull/319">Atmire&rsquo;s patch for the CUA Workflow Statistics again</a></li>
<li>Still doesn&rsquo;t seem to give results I&rsquo;d expect, like there are no results for Maria Garruccio, or for the ILRI community!</li>
<li>Then I&rsquo;ll file an update to the issue on Atmire&rsquo;s tracker</li>
<li>Created a new branch with just the relevant changes, so I can send it to them</li>
<li>One thing I noticed is that there is a failed database migration related to CUA:</li>

<ul>
<li>Import Abenet and Peter&rsquo;s changes to the CGIAR Library CRP community</li>
<li>Due to them using Windows and renaming some columns there were formatting, encoding, and duplicate metadata value issues</li>
<li>I had to remove some fields from the CSV and rename some back to, ie, <code>dc.subject[en_US]</code> just so DSpace would detect changes properly</li>

<li>After looking at the Tomcat logs, Munin graphs, and PostgreSQL connection stats, it seems there is just a high load</li>
<li>Might be a good time to adjust DSpace&rsquo;s database connection settings, like I first mentioned in April, 2017 after reading the <a href="https://wiki.lyrasis.org/display/cmtygp/DCAT+Meeting+April+2017">2017-04 DCAT comments</a></li>
<li>I&rsquo;ve adjusted the following in CGSpace&rsquo;s config:
<ul>
<li><code>db.maxconnections</code> 30→70 (the default PostgreSQL config allows 100 connections, so DSpace&rsquo;s default of 30 is quite low)</li>
<li><code>db.maxwait</code> 5000→10000</li>
<li><code>db.maxidle</code> 8→20 (DSpace default is -1, unlimited, but we had set it to 8 earlier)</li>
</ul>
</li>
<li>We will need to adjust this again (as well as the <code>pg_hba.conf</code> settings) when we deploy tsega&rsquo;s REST API</li>
<li>Whip up a test for Marianne of WLE to be able to show both their Phase I and II research themes in the CGSpace item submission form:</li>

<li>It works but is still very rough and we haven&rsquo;t thought out the whole lifecycle yet</li>
</ul>
<p><img src="/cgspace-notes/2017/07/lead-author-test.png" alt="Testing lead author in submission form"></p>
<ul>
<li>I assume that &ldquo;lead author&rdquo; would actually be the first question on the item submission form</li>
<li>We also need to check to see which ORCID authority core this uses, because it seems to be using an entirely new one rather than the one for <code>dc.contributor.author</code> (which makes sense of course, but fuck, all the author problems aren&rsquo;t bad enough?!)</li>
<li>Also would need to edit XMLUI item displays to incorporate this into authors list</li>
<li>And fuck, then anyone consuming our data via REST / OAI will not notice that we have an author outside of <code>dc.contributor.authors</code>&hellip; ugh</li>
<li>What if we modify the item submission form to use <a href="https://wiki.lyrasis.org/display/DSDOC5x/Submission+User+Interface#SubmissionUserInterface-ItemtypeBasedMetadataCollection"><code>type-bind</code> fields to show/hide certain fields depending on the type</a>?</li>
</ul>
<h2 id="2017-07-05">2017-07-05</h2>
<ul>
<li>Adjust WLE Research Theme to include both Phase I and II on the submission form according to editor feedback (<a href="https://github.com/ilri/DSpace/pull/330">#330</a>)</li>
<li>Generate list of fields in the current CGSpace <code>cg</code> scheme so we can record them properly in the metadata registry:</li>
</ul>
<pre tabindex="0"><code>$ psql dspace -x -c &#39;select element, qualifier, scope_note from metadatafieldregistry where metadata_schema_id=2 order by element, qualifier;&#39; | sed -r &#39;s:^-\[ RECORD (.*) \]-+$:&lt;/dc-type&gt;\n&lt;dc-type&gt;\n&lt;schema&gt;cg&lt;/schema&gt;:;s:([^ ]*) +\| (.*): &lt;\1&gt;\2&lt;/\1&gt;:;s:^$:&lt;/dc-type&gt;:;1s:&lt;/dc-type&gt;\n::&#39; &gt; cg-types.xml

<li>CGSpace was unavailable briefly, and I saw this error in the DSpace log file:</li>
</ul>
<pre tabindex="0"><code>2017-07-05 13:05:36,452 ERROR org.dspace.storage.rdbms.DatabaseManager @ SQL connection Error -

</code></pre><ul>
<li>Looking at the <code>pg_stat_activity</code> table I saw there were indeed 98 active connections to PostgreSQL, and at this time the limit is 100, so that makes sense</li>
<li>Tsega restarted Tomcat and it&rsquo;s working now</li>
<li>Abenet said she was generating a report with Atmire&rsquo;s CUA module, so it could be due to that?</li>
<li>Looking in the logs I see this random error again that I should report to DSpace:</li>

<li>Sisay tried to help by making a <a href="https://github.com/ilri/DSpace/pull/331">pull request for the RTB flagships</a> but there are formatting errors, unrelated changes, and the flagship names are not in the style I requested</li>
<li>Abenet talked to CIP and they said they are actually ok with using collection names rather than adding a new metadata field</li>
</ul>
<h2 id="2017-07-13">2017-07-13</h2>
<ul>
<li>Remove <code>UKaid</code> from the controlled vocabulary for <code>dc.description.sponsorship</code>, as <code>Department for International Development, United Kingdom</code> is the correct form and it is already present (<a href="https://github.com/ilri/DSpace/pull/334">#334</a>)</li>

<li>Linode shut down our seventeen (17) VMs due to nonpayment of the July 1st invoice</li>
<li>It took me a few hours to find the ICT/Finance contacts to pay the bill and boot all the servers back up</li>
<li>Since the server was down anyways, I decided to run all system updates and re-deploy CGSpace so that the latest changes to <code>input-forms.xml</code> and the sponsors controlled vocabulary</li>

<li>Talk to Tsega and Danny about exporting/injesting the blog posts from Drupal into DSpace?</li>
<li>Followup meeting on August 8/9?</li>
<li>Sent Abenet the 2415 records from CGIAR Library&rsquo;s Historical Archive (10947/1) after cleaning up the author authorities and HTML entities in <code>dc.contributor.author</code> and <code>dc.description.abstract</code> using OpenRefine:

<li>Help Sisay with some transforms to add descriptions to the <code>filename</code> column of some CIAT Presentations he&rsquo;s working on in OpenRefine</li>
<li>Marianne emailed a few days ago to ask why &ldquo;Integrating Ecosystem Solutions&rdquo; was not in the list of WLE Phase I Research Themes on the input form</li>
<li>I told her that I only added the themes that I saw in the <a href="https://cgspace.cgiar.org/handle/10568/34508">WLE Phase I Research Themes</a> community</li>
<li>Then Mia from WLE also emailed to ask where some WLE focal regions went, and I said I didn&rsquo;t understand what she was talking about, as all we did in our previous work was rename the old &ldquo;Research Themes&rdquo; subcommunity to &ldquo;WLE Phase I Research Themes&rdquo; and add a new subcommunity for &ldquo;WLE Phase II Research Themes&rdquo;.</li>

<li>Discuss updates to the Phase II CCAFS project tags with Andrea from Macaroni Bros</li>
<li>I will do the renaming and untagging of items in CGSpace database, and he will update his webservice with the latest project tags and I will get the XML from here for our <code>input-forms.xml</code>: <a href="https://ccafs.cgiar.org/export/ccafsproject">https://ccafs.cgiar.org/export/ccafsproject</a></li>

Linode sent an alert that CGSpace (linode18) was using 350% CPU for the past two hours
I looked in the Activity pane of the Admin Control Panel and it seems that Google, Baidu, Yahoo, and Bing are all crawling with massive numbers of bots concurrently (~100 total, mostly Baidu and Google)
The good thing is that, according to dspace.log.2017-08-01, they are all using the same Tomcat session
This means our Tomcat Crawler Session Valve is working
But many of the bots are browsing dynamic URLs like:
/handle/10568/3353/discover
/handle/10568/16510/browse
The robots.txt only blocks the top-level /discover and /browse URLs&hellip; we will need to find a way to forbid them from accessing these!
Relevant issue from DSpace Jira (semi resolved in DSpace 6.0): https://jira.duraspace.org/browse/DS-2962
It turns out that we&rsquo;re already adding the X-Robots-Tag &quot;none&quot; HTTP header, but this only forbids the search engine from indexing the page, not crawling it!
Also, the bot has to successfully browse the page first so it can receive the HTTP header&hellip;
We might actually have to block these requests with HTTP 403 depending on the user agent
Abenet pointed out that the CGIAR Library Historical Archive collection I sent July 20th only had ~100 entries, instead of 2415
This was due to newline characters in the dc.description.abstract column, which caused OpenRefine to choke when exporting the CSV
I exported a new CSV from the collection on DSpace Test and then manually removed the characters in vim using g/^$/d
Then I cleaned up the author authorities and HTML characters in OpenRefine and sent the file back to Abenet

<li>Magdalena from CCAFS asked if there was a way to get the top ten items published in 2016 (note: not the top items in 2016!)</li>
<li>I think Atmire&rsquo;s Content and Usage Analysis module should be able to do this but I will have to look at the configuration and maybe email Atmire if I can&rsquo;t figure it out</li>
<li>I had a look at the moduel configuration and couldn&rsquo;t figure out a way to do this, so I <a href="https://tracker.atmire.com/tickets-cgiar-ilri/view-tickets">opened a ticket on the Atmire tracker</a></li>
<li>Atmire responded about the <a href="https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=500">missing workflow statistics issue</a> a few weeks ago but I didn&rsquo;t see it for some reason</li>

<li>Usman from CIFOR emailed to ask about the status of our OAI tests for harvesting their DSpace repository</li>
<li>I told him that the OAI appears to not be harvesting properly after the first sync, and that the control panel shows an &ldquo;Internal error&rdquo; for that collection:</li>
</ul>
<p><img src="/cgspace-notes/2017/08/cifor-oai-harvesting.png" alt="CIFOR OAI harvesting"></p>
<ul>
<li>I don&rsquo;t see anything related in our logs, so I asked him to check for our server&rsquo;s IP in their logs</li>
<li>Also, in the mean time I stopped the harvesting process, reset the status, and restarted the process via the Admin control panel (note: I didn&rsquo;t reset the collection, just the harvester status!)</li>

<ul>
<li>Apply Abenet&rsquo;s corrections for the CGIAR Library&rsquo;s Consortium subcommunity (697 records)</li>
<li>I had to fix a few small things, like moving the <code>dc.title</code> column away from the beginning of the row, delete blank spaces in the abstract in vim using <code>:g/^$/d</code>, add the <code>dc.subject[en_US]</code> column back, as she had deleted it and DSpace didn&rsquo;t detect the changes made there (we needed to blank the values instead)</li>

<ul>
<li>We had to import the PostgreSQL dump to the PostgreSQL container using: <code>pg_restore -U postgres -d dspace blah.dump</code></li>
<li>Otherwise, when using <code>-O</code> it messes up the permissions on the schema and DSpace can&rsquo;t read it</li>

<li>Apply last updates to the CGIAR Library&rsquo;s Fund community (812 items)</li>
<li>Had to do some quality checks and column renames before importing, as either Sisay or Abenet renamed a few columns and the metadata importer wanted to remove/add new metadata for title, abstract, etc.</li>
<li>Also I applied the HTML entities unescape transform on the abstract column in Open Refine</li>
<li>I need to get an author list from the database for only the CGIAR Library community to send to Peter</li>

<ul>
<li>CGSpace had load issues and was throwing errors related to PostgreSQL</li>
<li>I told Tsega to reduce the max connections from 70 to 40 because actually each web application gets that limit and so for xmlui, oai, jspui, rest, etc it could be 70 x 4 = 280 connections depending on the load, and the PostgreSQL config itself is only 100!</li>
<li>I learned this on a recent discussion on the DSpace wiki</li>
<li>I need to either look into setting up a database pool through JNDI or increase the PostgreSQL max connections</li>
<li>Also, I need to find out where the load is coming from (rest?) and possibly block bots from accessing dynamic pages like Browse and Discover instead of just sending an X-Robots-Tag HTTP header</li>
<li>I noticed that Google has bitstreams from the <code>rest</code> interface in the search index. I need to ask on the dspace-tech mailing list to see what other people are doing about this, and maybe start issuing an <code>X-Robots-Tag: none</code> there!</li>

<li>Thinking about resource limits for PostgreSQL again after last week&rsquo;s CGSpace crash and related to a recently discussion I had in the comments of the <a href="https://wiki.lyrasis.org/display/cmtygp/DCAT+Meeting+April+2017">April, 2017 DCAT meeting notes</a></li>
<li>In that thread Chris Wilper suggests a new default of 35 max connections for <code>db.maxconnections</code> (from the current default of 30), knowing that <em>each DSpace web application</em> gets to use up to this many on its own</li>
<li>It would be good to approximate what the theoretical maximum number of connections on a busy server would be, perhaps by looking to see which apps use SQL:</li>
</ul>
<pre tabindex="0"><code>$ grep -rsI SQLException dspace-jspui | wc -l
473
$ grep -rsI SQLException dspace-oai | wc -l
63
$ grep -rsI SQLException dspace-rest | wc -l
139
$ grep -rsI SQLException dspace-solr | wc -l
0
$ grep -rsI SQLException dspace-xmlui | wc -l
866
</code></pre><ul>
<li>Of those five applications we&rsquo;re running, only <code>solr</code> appears not to use the database directly</li>
<li>And JSPUI is only used internally (so it doesn&rsquo;t really count), leaving us with OAI, REST, and XMLUI</li>
<li>Assuming each takes a theoretical maximum of 35 connections during a heavy load (35 * 3 = 105), that would put the connections well above PostgreSQL&rsquo;s default max of 100 connections (remember a handful of connections are reserved for the PostgreSQL super user, see <code>superuser_reserved_connections</code>)</li>
<li>So we should adjust PostgreSQL&rsquo;s max connections to be DSpace&rsquo;s <code>db.maxconnections</code> * 3 + 3</li>
<li>This would allow each application to use up to <code>db.maxconnections</code> and not to go over the system&rsquo;s PostgreSQL limit</li>
<li>Perhaps since CGSpace is a busy site with lots of resources we could actually use something like 40 for <code>db.maxconnections</code></li>
<li>Also worth looking into is to set up a database pool using JNDI, as apparently DSpace&rsquo;s <code>db.poolname</code> hasn&rsquo;t been used since around DSpace 1.7 (according to Chris Wilper&rsquo;s comments in the thread)</li>
<li>Need to go check the PostgreSQL connection stats in Munin on CGSpace from the past week to get an idea if 40 is appropriate</li>
<li>Looks like connections hover around 50:</li>
</ul>
<p><img src="/cgspace-notes/2017/08/postgresql-connections-cgspace.png" alt="PostgreSQL connections 2017-08"></p>
<ul>
<li>Unfortunately I don&rsquo;t have the breakdown of which DSpace apps are making those connections (I&rsquo;ll assume XMLUI)</li>
<li>So I guess a limit of 30 (DSpace default) is too low, but 70 causes problems when the load increases and the system&rsquo;s PostgreSQL <code>max_connections</code> is too low</li>
<li>For now I think maybe setting DSpace&rsquo;s <code>db.maxconnections</code> to 40 and adjusting the system&rsquo;s <code>max_connections</code> might be a good starting point: 40 * 3 + 3 = 123</li>

<li>Metadata fields like <code>dc.contributor.author</code>, <code>dc.publisher</code>, <code>dc.type</code>, and a few others had somehow been duplicated along the line</li>
<li>Also, a few dozen <code>dc.description.abstract</code> fields still had various HTML tags and entities in them</li>

<li>Wow, I just wrote this baller regex facet to find duplicate authors:</li>
</ul>
<pre tabindex="0"><code>isNotNull(value.match(/(CGIAR .+?)\|\|\1/))
</code></pre><ul>
<li>This would be true if the authors were like <code>CGIAR System Management Office||CGIAR System Management Office</code>, which some of the CGIAR Library&rsquo;s were</li>
<li>Unfortunately when you fix these in OpenRefine and then submit the metadata to DSpace it doesn&rsquo;t detect any changes, so you have to edit them all manually via DSpace&rsquo;s &ldquo;Edit Item&rdquo;</li>
<li>Ooh! And an even more interesting regex would match <em>any</em> duplicated author:</li>
</ul>
<pre tabindex="0"><code>isNotNull(value.match(/(.+?)\|\|\1/))
</code></pre><ul>
<li>Which means it can also be used to find items with duplicate <code>dc.subject</code> fields&hellip;</li>
<li>Finally sent Peter the final dump of the CGIAR System Organization community so he can have a last look at it</li>
<li>Post a message to the dspace-tech mailing list to ask about querying the AGROVOC API from the submission form</li>
<li>Abenet was asking if there was some way to hide certain internal items from the &ldquo;ILRI Research Outputs&rdquo; RSS feed (which is the top-level ILRI community feed), because Shirley was complaining</li>
<li>I think we could use <code>harvest.includerestricted.rss = false</code> but the items might need to be 100% restricted, not just the metadata</li>
<li>Adjust Ansible postgres role to use <code>max_connections</code> from a template variable and deploy a new limit of 123 on CGSpace</li>

<li>We tested the option for limiting restricted items from the RSS feeds on DSpace Test</li>

<li>He linked to some examples from DSpace-CRIS that use this functionality: <a href="https://github.com/4Science/DSpace/blob/dspace-5_x_x-cris/dspace-api/src/main/java/org/dspace/content/authority/VIAFAuthority.java">VIAFAuthority</a></li>
<li>I wired it up to the <code>dc.subject</code> field of the submission interface using the &ldquo;lookup&rdquo; type and it works!</li>

<li>I notice that in many WLE collections Marianne Gadeberg is in the edit or approval steps, but she is also in the groups for those steps.</li>
<li>I think we need to have a process to go back and check / fix some of these scenarios—to remove her user from the step and instead add her to the group—because we have way too many authorizations and in late 2016 we had <a href="https://github.com/ilri/rmg-ansible-public/commit/358b5ea43f9e5820986f897c9d560937c702ac6e">performance issues with Solr</a> because of this</li>
<li>I asked Sisay about this and hinted that he should go back and fix these things, but let&rsquo;s see what he says</li>

<li>Looking at the logs I see we have been having hundreds or thousands of these errors a few times per week in 2017-07 and almost every day in 2017-08</li>
<li>It seems that I changed the <code>db.maxconnections</code> setting from 70 to 40 around 2017-08-14, but Macaroni Bros also reduced their hourly hammering of the REST API then</li>
<li>Nevertheless, it seems like a connection limit is not enough and that I should increase it (as well as the system&rsquo;s PostgreSQL <code>max_connections</code>)</li>

<li>Create pull request for Phase I and II changes to CCAFS Project Tags: <a href="https://github.com/ilri/DSpace/pull/336">#336</a></li>
<li>We&rsquo;ve been discussing with Macaroni Bros and CCAFS for the past month or so and the list of tags was recently finalized</li>
<li>There will need to be some metadata updates — though if I recall correctly it is only about seven records — for that as well, I had made some notes about it in <a href="/cgspace-notes/2017-07">2017-07</a>, but I&rsquo;ve asked for more clarification from Lili just in case</li>
<li>Looking at the DSpace logs to see if we&rsquo;ve had a change in the &ldquo;Cannot get a connection&rdquo; errors since last month when we adjusted the <code>db.maxconnections</code> parameter on CGSpace:</li>

<li>Also, since last month (2017-08) Macaroni Bros no longer runs their REST API scraper every hour, so I&rsquo;m sure that helped</li>
<li>There are still some errors, though, so maybe I should bump the connection limit up a bit</li>
<li>I remember seeing that Munin shows that the average number of connections is 50 (which is probably mostly from the XMLUI) and we&rsquo;re currently allowing 40 connections per app, so maybe it would be good to bump that value up to 50 or 60 along with the system&rsquo;s PostgreSQL <code>max_connections</code> (formula should be: webapps * 60 + 3, or 3 * 60 + 3 = 183 in our case)</li>
<li>I updated both CGSpace and DSpace Test to use these new settings (60 connections per web app and 183 for system PostgreSQL limit)</li>
<li>I&rsquo;m expecting to see 0 connection errors for the next few months</li>

<li>I was testing the <a href="https://wiki.lyrasis.org/display/DSDOC5x/AIP+Backup+and+Restore#AIPBackupandRestore-AIPConfigurationsToImproveIngestionSpeedwhileValidating">METS XSD caching during AIP ingest</a> but it doesn&rsquo;t seem to help actually</li>
<li>The import process takes the same amount of time with and without the caching</li>
<li>Also, I captured TCP packets destined for port 80 and both imports only captured ONE packet (an update check from some component in Java):</li>
</ul>
<pre tabindex="0"><code>$ sudo tcpdump -i en0 -w without-cached-xsd.dump dst port 80 and &#39;tcp[32:4] = 0x47455420&#39;
</code></pre><ul>
<li>Great TCP dump guide here: <a href="https://danielmiessler.com/study/tcpdump">https://danielmiessler.com/study/tcpdump</a></li>
<li>The last part of that command filters for HTTP GET requests, of which there should have been many to fetch all the XSD files for validation</li>
<li>I sent a message to the mailing list to see if anyone knows more about this</li>
<li>In looking at the tcpdump results I notice that there is an update check to the ehcache server on <em>every</em> iteration of the ingest loop, for example:</li>
</ul>
<pre tabindex="0"><code>09:39:36.008956 IP 192.168.8.124.50515 &gt; 157.189.192.67.http: Flags [P.], seq 1736833672:1736834103, ack 147469926, win 4120, options [nop,nop,TS val 1175113331 ecr 550028064], length 431: HTTP: GET /kit/reflector?kitID=ehcache.default&amp;pageID=update.properties&amp;id=2130706433&amp;os-name=Mac+OS+X&amp;jvm-name=Java+HotSpot%28TM%29+64-Bit+Server+VM&amp;jvm-version=1.8.0_144&amp;platform=x86_64&amp;tc-version=UNKNOWN&amp;tc-product=Ehcache+Core+1.7.2&amp;source=Ehcache+Core&amp;uptime-secs=0&amp;patch=UNKNOWN HTTP/1.1

<li>Turns out this is a known issue and Ehcache has refused to make it opt-in: <a href="https://jira.terracotta.org/jira/browse/EHC-461">https://jira.terracotta.org/jira/browse/EHC-461</a></li>
<li>But we can disable it by adding an <code>updateCheck=&quot;false&quot;</code> attribute to the main <code>&lt;ehcache &gt;</code> tag in <code>dspace-services/src/main/resources/caching/ehcache-config.xml</code></li>
<li>After re-compiling and re-deploying DSpace I no longer see those update checks during item submission</li>
<li>I had a Skype call with Bram Luyten from Atmire to discuss various issues related to ORCID in DSpace
<ul>
<li>First, ORCID is deprecating their version 1 API (which DSpace uses) and in version 2 API they have removed the ability to search for users by name</li>
<li>The logic is that searching by name actually isn&rsquo;t very useful because ORCID is essentially a global phonebook and there are tons of legitimately duplicate and ambiguous names</li>
<li>Atmire&rsquo;s proposed integration would work by having users lookup and add authors to the authority core directly using their ORCID ID itself (this would happen during the item submission process or perhaps as a standalone / batch process, for example to populate the authority core with a list of known ORCIDs)</li>
<li>Once the association between name and ORCID is made in the authority then it can be autocompleted in the lookup field</li>
<li>Ideally there could also be a user interface for cleanup and merging of authorities</li>
<li>He will prepare a quote for us with keeping in mind that this could be useful to contribute back to the community for a 5.x release</li>
<li>As far as exposing ORCIDs as flat metadata along side all other metadata, he says this should be possible and will work on a quote for us</li>

<li>Michael Marus is the contact for their prefix but he has left CGIAR, but as I actually have access to the CGIAR Library server I think I can just generate a new <code>sitebndl.zip</code> file from their server and send it to Handle.net</li>

<li>CGSpace was very slow and Uptime Robot even said it was down at one time</li>
<li>I didn&rsquo;t see any abnormally high usage in the REST or OAI logs, but looking at Munin I see the average JVM usage was at 4.9GB and the heap is only 5GB (5120M), so I think it&rsquo;s just normal growing pains</li>

<li>More work on the CGIAR Library migration test run locally, as I was having problem with importing the last fourteen items from the CGIAR System Management Office community</li>
<li>The problem was that we remapped the items to new collections after the initial import, so the items were using the 10947 prefix but the community and collection was using 10568</li>
<li>I ended up having to read the <a href="https://wiki.lyrasis.org/display/DSDOC5x/AIP+Backup+and+Restore#AIPBackupandRestore-ForceReplaceMode">AIP Backup and Restore</a> closely a few times and then explicitly preserve handles and ignore parents:</li>

<li>Also, this was in replace mode (-r) rather than submit mode (-s), because submit mode always generated a new handle even if I told it not to!</li>
<li>I decided to start the import process in the evening rather than waiting for the morning, and right as the first community was finished importing I started seeing <code>Timeout waiting for idle object</code> errors</li>
<li>I had to cancel the import, clean up a bunch of database entries, increase the PostgreSQL <code>max_connections</code> as a precaution, restart PostgreSQL and Tomcat, and then finally completed the import</li>

<li>Start investigating other platforms for CGSpace due to linear instance pricing on Linode</li>
<li>We need to figure out how much memory is used by applications, caches, etc, and how much disk space the asset store needs</li>
<li>First, here&rsquo;s the last week of memory usage on CGSpace and DSpace Test:</li>
</ul>
<p><img src="/cgspace-notes/2017/09/cgspace-memory-week.png" alt="CGSpace memory week">
<img src="/cgspace-notes/2017/09/dspace-test-memory-week.png" alt="DSpace Test memory week"></p>
<ul>
<li>8GB of RAM seems to be good for DSpace Test for now, with Tomcat&rsquo;s JVM heap taking 3GB, caches and buffers taking 3–4GB, and then ~1GB unused</li>
<li>24GB of RAM is <em>way</em> too much for CGSpace, with Tomcat&rsquo;s JVM heap taking 5.5GB and caches and buffers happily using 14GB or so</li>
<li>As far as disk space, the CGSpace assetstore currently uses 51GB and Solr cores use 86GB (mostly in the statistics core)</li>
<li>DSpace Test currently doesn&rsquo;t even have enough space to store a full copy of CGSpace, as its Linode instance only has 96GB of disk space</li>
<li>I&rsquo;ve heard Google Cloud is nice (cheap and performant) but it&rsquo;s definitely more complicated than Linode and instances aren&rsquo;t <em>that</em> much cheaper to make it worth it</li>
<li>Here are some theoretical instances on Google Cloud:
<ul>
<li>DSpace Test, <code>n1-standard-2 </code> with 2 vCPUs, 7.5GB RAM, 300GB persistent SSD: $99/month</li>
<li>CGSpace, <code>n1-standard-4 </code> with 4 vCPUs, 15GB RAM, 300GB persistent SSD: $148/month</li>
</ul>
</li>
<li>Looking at <a href="https://www.linode.com/pricing#all">Linode&rsquo;s instance pricing</a>, for DSpace Test it seems we could use the same 8GB instance for $40/month, and then add <a href="https://www.linode.com/docs/platform/how-to-use-block-storage-with-your-linode">block storage</a> of ~300GB for $30 (block storage is currently in beta and priced at $0.10/GiB)</li>
<li>For CGSpace we could use the cheaper 12GB instance for $80 and then add block storage of 500GB for $50</li>
<li>I&rsquo;ve sent Peter a message about moving DSpace Test to the New Jersey data center so we can test the block storage beta</li>
<li>Create pull request for adding ISI Journal to search filters (<a href="https://github.com/ilri/DSpace/pull/341">#341</a>)</li>
<li>Peter asked if we could map all the items of type <code>Journal Article</code> in <a href="https://cgspace.cgiar.org/handle/10568/2703">ILRI Archive</a> to <a href="https://cgspace.cgiar.org/handle/10568/3">ILRI articles in journals and newsletters</a></li>
<li>It is easy to do via CSV using OpenRefine but I noticed that on CGSpace ~1,000 of the expected 2,500 are already mapped, while on DSpace Test they were not</li>
<li>I&rsquo;ve asked Peter if he knows what&rsquo;s going on (or who mapped them)</li>
<li>Turns out he had already mapped some, but requested that I finish the rest</li>
<li>With this GREL in OpenRefine I can find items that are mapped, ie they have <code>10568/3||</code> or <code>10568/3$</code> in their <code>collection</code> field:</li>

<li>Peter Ballantyne said he was having problems logging into CGSpace with &ldquo;both&rdquo; of his accounts (CGIAR LDAP and personal, apparently)</li>

<li>I thought maybe his account had expired (seeing as it&rsquo;s was the first of the month) but he says he was finally able to log in today</li>

<li>For what it&rsquo;s worth, there are no errors on any other recent days, so it must have been some network issue on Linode or CGNET&rsquo;s LDAP server</li>
<li>Linode emailed to say that linode578611 (DSpace Test) needs to migrate to a new host for a security update so I initiated the migration immediately rather than waiting for the scheduled time in two weeks</li>

<li>Twice in the last twenty-four hours Linode has alerted about high CPU usage on CGSpace (linode2533629)</li>
<li>Communicate with Sam from the CGIAR System Organization about some broken links coming from their CGIAR Library domain to CGSpace</li>

<li>We&rsquo;ll need to check for browse links and handle them properly, including swapping the <code>subject</code> parameter for <code>systemsubject</code> (which doesn&rsquo;t exist in Discovery yet, but we&rsquo;ll need to add it) as we have moved their poorly curated subjects from <code>dc.subject</code> to <code>cg.subject.system</code></li>
<li>The second link was a direct link to a bitstream which has broken due to the sequence being updated, so I told him he should link to the handle of the item instead</li>
<li>Help Sisay proof sixty-two IITA records on DSpace Test</li>
<li>Lots of inconsistencies and errors in subjects, dc.format.extent, regions, countries</li>

<li>Working on the nginx redirects for CGIAR Library</li>
<li>We should start using 301 redirects and also allow for <code>/sitemap</code> to work on the library.cgiar.org domain so the CGIAR System Organization people can update their Google Search Console and allow Google to find their content in a structured way</li>
<li>Remove eleven occurrences of <code>ACP</code> in IITA&rsquo;s <code>cg.coverage.region</code> using the Atmire batch edit module from Discovery</li>
<li>Need to investigate how we can verify the library.cgiar.org using the HTML or DNS methods</li>
<li>Run corrections on 143 ILRI Archive items that had two <code>dc.identifier.uri</code> values (Handle) that Peter had pointed out earlier this week</li>
<li>I used OpenRefine to isolate them and then fixed and re-imported them into CGSpace</li>
<li>I manually checked a dozen of them and it appeared that the correct handle was always the second one, so I just deleted the first one</li>

<ul>
<li>I&rsquo;ll post it to the Yammer group to see what people think</li>
<li>I figured out at way to do the HTML verification for Google Search console for library.cgiar.org</li>
<li>We can drop the HTML file in their XMLUI theme folder and it will get copied to the webapps directory during build/install</li>
<li>Then we add an nginx alias for that URL in the library.cgiar.org vhost</li>
<li>This method is kinda a hack but at least we can put all the pieces into git to be reproducible</li>
<li>I will tell Tunji to send me the verification file</li>

<ul>
<li>Deploy logic to allow verification of the library.cgiar.org domain in the Google Search Console (<a href="https://github.com/ilri/DSpace/pull/343">#343</a>)</li>
<li>After verifying both the HTTP and HTTPS domains and submitting a sitemap it will be interesting to see how the stats in the console as well as the search results change (currently 28,500 results):</li>

<li>I tried to submit a &ldquo;Change of Address&rdquo; request in the Google Search Console but I need to be an owner on CGSpace&rsquo;s console (currently I&rsquo;m just a user) in order to do that</li>

<li>Peter added me as an owner on the CGSpace property on Google Search Console and I tried to submit a &ldquo;Change of Address&rdquo; request for the CGIAR Library but got an error:</li>
</ul>
<p><img src="/cgspace-notes/2017/10/search-console-change-address-error.png" alt="Change of Address error"></p>
<ul>
<li>We are sending top-level CGIAR Library traffic to their specific community hierarchy in CGSpace so this type of change of address won&rsquo;t work—we&rsquo;ll just need to wait for Google to slowly index everything and take note of the HTTP 301 redirects</li>
<li>Also the Google Search Console doesn&rsquo;t work very well with Google Analytics being blocked, so I had to turn off my ad blocker to get the &ldquo;Change of Address&rdquo; tool to work!</li>
</ul>
<h2 id="2017-10-12">2017-10-12</h2>
<ul>
<li>Finally finish (I think) working on the myriad nginx redirects for all the CGIAR Library browse stuff—it ended up getting pretty complicated!</li>
<li>I still need to commit the DSpace changes (add browse index, XMLUI strings, Discovery index, etc), but I should be able to deploy that on CGSpace soon</li>

<li>Run system updates on DSpace Test and reboot server</li>

<ul>
<li>In the last 24 hours we&rsquo;ve gotten a few alerts from Linode that there was high CPU and outgoing traffic on CGSpace</li>
<li>Uptime Robot even noticed CGSpace go &ldquo;down&rdquo; for a few minutes</li>
<li>In other news, I was trying to look at a question about stats raised by Magdalena and then CGSpace went down due to SQL connection pool</li>
<li>Looking at the PostgreSQL activity I see there are 93 connections, but after a minute or two they went down and CGSpace came back up</li>
<li>Annnd I reloaded the Atmire Usage Stats module and the connections shot back up and CGSpace went down again</li>
<li>Still not sure where the load is coming from right now, but it&rsquo;s clear why there were so many alerts yesterday on the 25th!</li>

<li>I still have no idea what was causing the load to go up today</li>

<li>I think it might have been an issue with the statistics not being fresh</li>
<li>I added the admin group for the systems organization to the admin role of the top-level community of CGSpace because I guess Sisay had forgotten</li>
<li>Magdalena asked if there was a way to reuse data in item submissions where items have a lot of similar data</li>
<li>I told her about the possibility to use per-collection item templates, and asked if her items in question were all from a single collection</li>
<li>We&rsquo;ve never used it but it could be worth looking at</li>

<ul>
<li>Linode alerted about high CPU usage again on CGSpace around 2AM and 4AM</li>
<li>I&rsquo;m still not sure why this started causing alerts so repeatadely the past week</li>
<li>I don&rsquo;t see any tell tale signs in the REST or OAI logs, so trying to do rudimentary analysis in DSpace logs:</li>

<li>So there were 2049 unique sessions during the hour of 2AM</li>
<li>Looking at my notes, the number of unique sessions was about the same during the same hour on other days when there were no alerts</li>
<li>I think I&rsquo;ll need to enable access logging in nginx to figure out what&rsquo;s going on</li>
<li>After enabling logging on requests to XMLUI on <code>/</code> I see some new bot I&rsquo;ve never seen before:</li>

<li>CORE seems to be some bot that is &ldquo;Aggregating the world’s open access research papers&rdquo;</li>

<li>I will check the logs in a few days to see if they are harvesting us regularly, then add their bot&rsquo;s user agent to the Tomcat Crawler Session Valve</li>
<li>After browsing the CORE site it seems that the CGIAR Library is somehow a member of CORE, so they have probably only been harvesting CGSpace since we did the migration, as library.cgiar.org directs to us now</li>
<li>For now I will just contact them to have them update their contact info in the bot&rsquo;s user agent, but eventually I think I&rsquo;ll tell them to swap out the CGIAR Library entry for CGSpace</li>

<li>Actually, according to the Tomcat docs, we could use an IP with <code>crawlerIps</code>: <a href="https://tomcat.apache.org/tomcat-7.0-doc/config/valve.html#Crawler_Session_Manager_Valve">https://tomcat.apache.org/tomcat-7.0-doc/config/valve.html#Crawler_Session_Manager_Valve</a></li>
<li>Ah, wait, it looks like <code>crawlerIps</code> only came in 2017-06, so probably isn&rsquo;t in Ubuntu 16.04&rsquo;s 7.0.68 build!</li>
<li>That would explain the errors I was getting when trying to set it:</li>
</ul>
<pre tabindex="0"><code>WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Valve} Setting property &#39;crawlerIps&#39; to &#39;190\.19\.92\.5|104\.196\.152\.243&#39; did not find a matching property.
</code></pre><ul>
<li>As for now, it actually seems the CORE bot coming from 137.108.70.6 and 137.108.70.7 is only using a few sessions per day, which is good:</li>
</ul>

<li>Very nice, Linode alerted that CGSpace had high CPU usage at 2AM again</li>
<li>Ask on the dspace-tech mailing list if it&rsquo;s possible to use an existing item as a template for a new item</li>
<li>To follow up on the CORE bot traffic, there were almost 300,000 request yesterday:</li>
</ul>
<pre tabindex="0"><code># grep &#34;CORE/0.6&#34; /var/log/nginx/access.log.1 | awk &#39;{print $1}&#39; | sort -n | uniq -c | sort -h

139253 137.108.70.7
</code></pre><ul>
<li>I&rsquo;ve emailed the CORE people to ask if they can update the repository information from CGIAR Library to CGSpace</li>
<li>Also, I asked if they could perhaps use the <code>sitemap.xml</code>, OAI-PMH, or REST APIs to index us more efficiently, because they mostly seem to be crawling the nearly endless Discovery facets</li>
<li>I added <a href="https://goaccess.io/">GoAccess</a> to the list of package to install in the DSpace role of the <a href="https://github.com/ilri/rmg-ansible-public">Ansible infrastructure scripts</a></li>
<li>It makes it very easy to analyze nginx logs from the command line, to see where traffic is coming from:</li>
</ul>
<pre tabindex="0"><code># goaccess /var/log/nginx/access.log --log-format=COMBINED
</code></pre><ul>
<li>According to Uptime Robot CGSpace went down and up a few times</li>
<li>I had a look at goaccess and I saw that CORE was actively indexing</li>
<li>Also, PostgreSQL connections were at 91 (with the max being 60 per web app, hmmm)</li>
<li>I&rsquo;m really starting to get annoyed with these guys, and thinking about blocking their IP address for a few days to see if CGSpace becomes more stable</li>
<li>Actually, come to think of it, they aren&rsquo;t even obeying <code>robots.txt</code>, because we actually disallow <code>/discover</code> and <code>/search-filter</code> URLs but they are hitting those massively:</li>
</ul>
<pre tabindex="0"><code># grep &#34;CORE/0.6&#34; /var/log/nginx/access.log | grep -o -E &#34;GET /(discover|search-filter)&#34; | sort -n | uniq -c | sort -rn
158058 GET /discover
14260 GET /search-filter
</code></pre><ul>
<li>I tested a URL of pattern <code>/discover</code> in Google&rsquo;s webmaster tools and it was indeed identified as blocked</li>
<li>I will send feedback to the CORE bot team</li>
</ul>

<li>Sisay re-uploaded the CIAT records that I had already corrected earlier this week, erasing all my corrections</li>

<li>Run system updates on DSpace Test and reboot the server</li>
<li>Magdalena had written to say that two of their Phase II project tags were missing on CGSpace, so I added them (<a href="https://github.com/ilri/DSpace/pull/346">#346</a>)</li>
<li>I figured out a way to use nginx&rsquo;s map function to assign a &ldquo;bot&rdquo; user agent to misbehaving clients who don&rsquo;t define a user agent</li>
<li>Most bots are automatically lumped into one generic session by <a href="https://tomcat.apache.org/tomcat-7.0-doc/config/valve.html#Crawler_Session_Manager_Valve">Tomcat&rsquo;s Crawler Session Manager Valve</a> but this only works if their user agent matches a pre-defined regular expression like <code>.*[bB]ot.*</code></li>
<li>Some clients send thousands of requests without a user agent which ends up creating thousands of Tomcat sessions, wasting precious memory, CPU, and database resources in the process</li>
<li>Basically, we modify the nginx config to add a mapping with a modified user agent <code>$ua</code>:</li>
</ul>
<pre tabindex="0"><code>map $remote_addr $ua {
# 2017-11-08 Random Chinese host grabbing 20,000 PDFs
124.17.34.59 &#39;ChineseBot&#39;;
default $http_user_agent;
}
</code></pre><ul>
<li>If the client&rsquo;s address matches then the user agent is set, otherwise the default <code>$http_user_agent</code> variable is used</li>
<li>Then, in the server&rsquo;s <code>/</code> block we pass this header to Tomcat:</li>
</ul>
<pre tabindex="0"><code>proxy_pass http://tomcat_http;
proxy_set_header User-Agent $ua;
</code></pre><ul>
<li>Note to self: the <code>$ua</code> variable won&rsquo;t show up in nginx access logs because the default <code>combined</code> log format doesn&rsquo;t show it, so don&rsquo;t run around pulling your hair out wondering with the modified user agents aren&rsquo;t showing in the logs!</li>
<li>If a client matching one of these IPs connects without a session, it will be assigned one by the Crawler Session Manager Valve</li>
<li>You can verify by cross referencing nginx&rsquo;s <code>access.log</code> and DSpace&rsquo;s <code>dspace.log.2017-11-08</code>, for example</li>
<li>I will deploy this on CGSpace later this week</li>
<li>I am interested to check how this affects the number of sessions used by the CIAT and Chinese bots (see above on <a href="#2017-11-07">2017-11-07</a> for example)</li>
<li>I merged the clickable thumbnails code to <code>5_x-prod</code> (<a href="https://github.com/ilri/DSpace/pull/347">#347</a>) and will deploy it later along with the new bot mapping stuff (and re-run the Asible <code>nginx</code> and <code>tomcat</code> tags)</li>

<li>I have been looking for a reason to ban Baidu and this is definitely a good one</li>

<li>I think we just need start increasing the number of allowed PostgreSQL connections instead of fighting this, as it&rsquo;s the most common source of crashes we have</li>
<li>I will bump DSpace&rsquo;s <code>db.maxconnections</code> from 60 to 90, and PostgreSQL&rsquo;s <code>max_connections</code> from 183 to 273 (which is using my loose formula of 90 * webapps + 3)</li>
<li>I really need to figure out how to get DSpace to use a PostgreSQL connection pool</li>

<li>Linode alerted about high CPU usage on CGSpace again around 6 to 8 AM</li>
<li>Then Uptime Robot said CGSpace was down a few minutes later, but it resolved itself I think (or Tsega restarted Tomcat, I don&rsquo;t know)</li>

<li>Linode alerted that CGSpace&rsquo;s load was 255.5% from 8 to 10 AM again</li>

<ul>
<li>The results look fantastic! So the <code>random_page_cost</code> tweak is massively important for informing the PostgreSQL scheduler that there is no &ldquo;cost&rdquo; to accessing random pages, as we&rsquo;re on an SSD!</li>
<li>I guess we could probably even reduce the PostgreSQL connections in DSpace / PostgreSQL after using this</li>
<li>Run system updates on DSpace Test (linode02) and reboot it</li>
<li>I&rsquo;m going to enable the PostgreSQL <code>random_page_cost</code> tweak on CGSpace</li>

<li>Reboot DSpace Test to get new Linode Linux kernel</li>
<li>Looking at CCAFS bulk import for Magdalena Haman (she originally sent them in November but some of the thumbnails were missing and dates were messed up so she resent them now)</li>
<li>A few issues with the data and thumbnails:
<ul>
<li>Her thumbnail files all use capital JPG so I had to rename them to lowercase: <code>rename -fc *.JPG</code></li>
<li>thumbnail20.jpg is 1.7MB so I have to resize it</li>
<li>I also had to add the .jpg to the thumbnail string in the CSV</li>
<li>The thumbnail11.jpg is missing</li>
<li>The dates are in super long ISO8601 format (from Excel?) like <code>2016-02-07T00:00:00Z</code> so I converted them to simpler forms in GREL: <code>value.toString(&quot;yyyy-MM-dd&quot;)</code></li>
<li>I trimmed the whitespaces in a few fields but it wasn&rsquo;t many</li>
<li>Rename her thumbnail column to filename, and format it so SAFBuilder adds the files to the thumbnail bundle with this GREL in OpenRefine: <code>value + &quot;__bundle:THUMBNAIL&quot;</code></li>
<li>Rename dc.identifier.status and dc.identifier.url columns to cg.identifier.status and cg.identifier.url</li>
<li>Item 4 has weird characters in citation, ie: Nagoya et de Trait</li>
<li>Some author names need normalization, ie: <code>Aggarwal, Pramod</code> and <code>Aggarwal, Pramod K.</code></li>
<li>Something weird going on with duplicate authors that have the same text value, like <code>Berto, Jayson C.</code> and <code>Balmeo, Katherine P.</code></li>
<li>I will send her feedback on some author names like UNEP and ICRISAT and ask her for the missing thumbnail11.jpg</li>
</ul>
</li>
<li>I did a test import of the data locally after building with SAFBuilder but for some reason I had to specify the collection (even though the collections were specified in the <code>collection</code> field)</li>

<li>Briefly had PostgreSQL connection issues on CGSpace for the millionth time</li>

<ul>
<li>And I only now just realized that DSpace&rsquo;s <code>db.maxidle</code> parameter is not seconds, but number of idle connections to allow.</li>
<li>So theoretically, because each webapp has its own pool, this could be 20 per app—so no wonder we have 50 idle connections!</li>

<li>If I add the db values back to dspace.cfg the <code>dspace database info</code> command succeeds but the log still shows errors retrieving the JNDI connection</li>
<li>Perhaps something to report to the dspace-tech mailing list when I finally send my comments</li>
<li>Oh cool! <code>select * from pg_stat_activity</code> shows &ldquo;PostgreSQL JDBC Driver&rdquo; for the application name! That&rsquo;s how you know it&rsquo;s working!</li>
<li>If you monitor the <code>pg_stat_activity</code> while you run <code>dspace database info</code> you can see that it doesn&rsquo;t use the JNDI and creates ~9 extra PostgreSQL connections!</li>
<li>And in the middle of all of this Linode sends an alert that CGSpace has high CPU usage from 2 to 4 PM</li>

<li>The database connection pooling is definitely better!</li>

<ul>
<li>Now there is only one set of idle connections shared among all the web applications, instead of 10+ per application</li>
<li>There are short bursts of connections up to 10, but it generally stays around 5</li>
<li>Test and import 13 records to CGSpace for Abenet:</li>

<li>The fucking database went from 47 to 72 to 121 connections while I was importing so it stalled.</li>
<li>Since I had to restart Tomcat anyways, I decided to just deploy the new JNDI connection pooling stuff on CGSpace</li>
<li>There was an initial connection storm of 50 PostgreSQL connections, but then it settled down to 7</li>
<li>After that CGSpace came up fine and I was able to import the 13 items just fine:</li>
