<li>Uptime Robot noticed that CGSpace went down and up a few times last night, for a few minutes each time</li>
|
|
<li>I didn’t get any load alerts from Linode and the REST and XMLUI logs don’t show anything out of the ordinary</li>
|
|
<li>The nginx logs show HTTP 200s until <code>02/Jan/2018:11:27:17 +0000</code> when Uptime Robot got an HTTP 500</li>
|
|
<li>In dspace.log around that time I see many errors like “Client closed the connection before file download was complete”</li>
|
|
<li>And just before that I see this:</li>
|
|
</ul>
|

|
|
<pre><code>Caused by: org.apache.tomcat.jdbc.pool.PoolExhaustedException: [http-bio-127.0.0.1-8443-exec-980] Timeout: Pool empty. Unable to fetch a connection in 5 seconds, none available[size:50; busy:50; idle:0; lastwait:5000].

<li>Ah hah! So the pool was actually empty!</li>

<li>I need to increase that, let’s try to bump it up from 50 to 75</li>
|
|
<li>After that one client got an HTTP 499 but then the rest were HTTP 200, so I don’t know what the hell Uptime Robot saw</li>

<li>I notice this error quite a few times in dspace.log:</li>

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

2017-06-01 After discussion with WLE and CGSpace content people, we decided to just add one metadata field for the WLE Research Themes The cg.identifier.wletheme field will be used for both Phase I and Phase II Research Themes Then we’ll create a new sub-community for Phase II and create collections for the research themes there The current “Research Themes” community will be renamed to “WLE Phase I Research Themes” Tagged all items in the current Phase I collections with their appropriate themes Create pull request to add Phase II research themes to the submission form: #328 Add cg.

2017-05-01 ICARDA apparently started working on CG Core on their MEL repository They have done a few cg.* fields, but not very consistent and even copy some of CGSpace items: https://mel.cgiar.org/xmlui/handle/20.500.11766/6911?show=full https://cgspace.cgiar.org/handle/10568/73683 2017-05-02 Atmire got back about the Workflow Statistics issue, and apparently it’s a bug in the CUA module so they will send us a pull request 2017-05-04 Sync DSpace Test with database and assetstore from CGSpace Re-deploy DSpace Test with Atmire’s CUA patch for workflow statistics, run system updates, and restart the server Now I can see the workflow statistics and am able to select users, but everything returns 0 items Megan says there are still some mapped items are not appearing since last week, so I forced a full index-discovery -b Need to remember to check if the collection has more items (currently 39 on CGSpace, but 118 on the freshly reindexed DSPace Test) tomorrow: https://cgspace.
