  • 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 “,” at the end of their names:

    dspacetest=# update metadatavalue set text_value = regexp_replace(text_value, '(^.+?),$', '\1') where metadata_field_id=3 and resource_type_id=2 and text_value ~ '^.+?,$';
    UPDATE 95
    dspacetest=# select text_value from  metadatavalue where metadata_field_id=3 and resource_type_id=2 and text_value ~ '^.+?,$';
    text_value
    ------------
    (0 rows)
    
  • In this case the select query was showing 95 results before the update

  • Since yesterday there have been 10,000 REST errors and the site has been unstable again
  • I have blocked access to the API now
  • There are 3,000 IPs accessing the REST API in a 24-hour period!

    # awk '{print $1}' /var/log/nginx/rest.log  | uniq | wc -l

  • 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’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’re paying for on S3
  • Also, I noticed the checker log has some errors we should pay attention to:

  • Looking at issues with author authorities on CGSpace
  • For some reason we still have the index-lucene-update cron job active on CGSpace, but I’m pretty sure we don’t need it as of the latest few versions of Atmire’s Listings and Reports module
  • 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

  • Looking at some DAGRIS data for Abenet Yabowork
  • Lots of issues with spaces, newlines, etc causing the import to fail
  • I noticed we have a very interesting list of countries on CGSpace:

CGSpace country list

  • Not only are there 49,000 countries, we have some blanks (25)…
  • Also, lots of things like “COTE D`LVOIRE” and “COTE D IVOIRE”

  • Move ILRI collection 10568/12503 from 10568/27869 to 10568/27629 using the move_collections.sh script I wrote last year.
  • I realized it is only necessary to clear the Cocoon cache after moving collections—rather than reindexing—as no metadata has changed, and therefore no search or browse indexes need to be updated.
  • Update GitHub wiki for documentation of maintenance tasks.

  • Replace lzop with xz in log compression cron jobs on DSpace Test—it uses less space:

    # cd /home/dspacetest.cgiar.org/log
    # ls -lh dspace.log.2015-11-18*
    -rw-rw-r-- 1 tomcat7 tomcat7 2.0M Nov 18 23:59 dspace.log.2015-11-18
    -rw-rw-r-- 1 tomcat7 tomcat7 387K Nov 18 23:59 dspace.log.2015-11-18.lzo

  • CGSpace went down
  • Looks like DSpace exhausted its PostgreSQL connection pool
  • Last week I had increased the limit from 30 to 60, which seemed to help, but now there are many more idle connections:

    $ psql -c 'SELECT * from pg_stat_activity;' | grep idle | grep -c cgspace
