- Continue working on porting CGSpace’s DSpace 5 code to DSpace 6.3 that I started yesterday
- Sign up for an account with MaxMind so I can get the GeoLite2-City.mmdb database
- I still need to wire up the API credentials and cron job into the Ansible infrastructure playbooks
- Fix some minor issues in the config and XMLUI themes, like removing Atmire stuff
- The code finally builds and runs with a fresh install
- Now we don’t specify the build environment because site modification are in
local.cfg, so we just build like this:
$ schedtool -D -e ionice -c2 -n7 nice -n19 mvn -U -Dmirage2.on=true -Dmirage2.deps.included=false clean package
- And it seems that we need to enabled
pg_crypto now (used for UUIDs):
$ psql -h localhost -U postgres dspace63
dspace63=# CREATE EXTENSION pgcrypto;
CREATE EXTENSION pgcrypto;
- I tried importing a PostgreSQL snapshot from CGSpace and had errors due to missing Atmire database migrations
- If I try to run
dspace database migrate I get the IDs of the migrations that are missing
- I delete them manually in psql:
dspace63=# DELETE FROM schema_version WHERE version IN ('5.0.2015.01.27', '5.6.2015.12.03.2', '5.6.2016.08.08', '5.0.2017.04.28', '5.0.2017.09.25', '5.8.2015.12.03.3');
- Then I ran
dspace database migrate and got an error:
$ ~/dspace63/bin/dspace database migrate
Database URL: jdbc:postgresql://localhost:5432/dspace63?ApplicationName=dspaceCli
Migrating database to latest version... (Check dspace logs for details)

- I think I might need to update the sequences first… nope
- Perhaps it’s due to some missing bitstream IDs and I need to run
dspace cleanup on CGSpace and take a new PostgreSQL dump… nope
- A thread on the dspace-tech mailing list regarding this migration noticed that his database had some views created that were using the
resource_id column
- Our database had the same issue, where the
eperson_metadata view was created by something (Atmire module?) but has no references in the vanilla DSpace code, so I dropped it and tried the migration again:
dspace63=# DROP VIEW eperson_metadata;
DROP VIEW
- After that the migration was successful and DSpace starts up successfully and begins indexing
- xmlui, solr, jspui, rest, and oai are working (rest was redirecting to HTTPS, so I set the Tomcat connector to
secure="true" and it fixed it on localhost, but caused other issues so I disabled it for now)
- I started diffing our themes against the Mirage 2 reference theme to capture the latest changes
2020-02-03
- Update DSpace mimetype fallback images from KDE Breeze Icons project
- Issues remaining in the DSpace 6 port of our CGSpace 5.x code:
- There are lots of errors in the DSpace log, which might explain some of the issues with recent submissions / Solr:
2020-02-03 10:27:14,485 ERROR org.dspace.browse.ItemCountDAOSolr @ caught exception:
org.dspace.discovery.SearchServiceException: Invalid UUID string: 1
2020-02-03 13:20:20,475 ERROR org.dspace.app.xmlui.aspect.discovery.AbstractRecentSubmissionTransformer @ Caught SearchServiceException while retrieving recent submission for: home page
org.dspace.discovery.SearchServiceException: Invalid UUID string: 111210
- If I look in Solr’s search core I do actually see items with integers for their resource ID, which I think are all supposed to be UUIDs now…
- I dropped all the documents in the search core:
$ http --print b 'http://localhost:8080/solr/search/update?stream.body=<delete><query>*:*</query></delete>&commit=true'
- Still didn’t work, so I’m going to try a clean database import and migration:
$ createdb -h localhost -U postgres -O dspacetest --encoding=UNICODE dspace63
$ psql -h localhost -U postgres -c 'alter user dspacetest superuser;'
$ pg_restore -h localhost -U postgres -d dspace63 -O --role=dspacetest -h localhost dspace_2020-01-27.backup
$ psql -h localhost -U postgres -c 'alter user dspacetest nosuperuser;'
$ psql -h localhost -U postgres dspace63
dspace63=# CREATE EXTENSION pgcrypto;
dspace63=# DELETE FROM schema_version WHERE version IN ('5.0.2015.01.27', '5.6.2015.12.03.2', '5.6.2016.08.08', '5.0.2017.04.28', '5.0.2017.09.25', '5.8.2015.12.03.3');
dspace63=# DROP VIEW eperson_metadata;
dspace63=# \q
$ psql -h localhost -U postgres -f ~/src/git/DSpace/dspace/etc/postgres/update-sequences.sql dspace63
$ ~/dspace63/bin/dspace database migrate
- I notice that the indexing doesn’t work correctly if I start it manually with
dspace index-discovery -b (search.resourceid becomes an integer!)
- If I induce an indexing by touching
dspace/solr/search/conf/reindex.flag the search.resourceid are all UUIDs…
- Speaking of database stuff, there was a performance-related update for the indexes that we used in DSpace 5
- We might want to apply it in DSpace 6, as it was never merged to 6.x, but it helped with the performance of
/submissions in XMLUI for us in 2018-03
2020-02-04
- The indexing issue I was having yesterday seems to only present itself the first time a new installation is running DSpace 6
- Once the indexing induced by touching
dspace/solr/search/conf/reindex.flag has finished, subsequent manual invocations of dspace index-discovery -b work as expected
- Nevertheless, I sent a message to the dspace-tech mailing list describing the issue to see if anyone has any comments
- I am seeing that the number of important commits on the unreleased DSpace 6.4 are really numerous and it might be better for us to target that version
- I did a simple test and it’s easy to rebase my current 6.3 branch on top of the upstream
dspace-6_x branch:
$ git checkout -b 6_x-dev64 6_x-dev
$ git rebase -i upstream/dspace-6_x
- I finally understand why our themes show all the “Browse by” buttons on community and collection pages in DSpace 6.x
- The code in
./dspace-xmlui/src/main/java/org/dspace/app/xmlui/aspect/browseArtifacts/CommunityBrowse.java iterates over all the browse indexes and prints them when it is called
- The XMLUI theme code in
dspace/modules/xmlui-mirage2/src/main/webapp/themes/0_CGIAR/xsl/preprocess/browse.xsl calls the template because the id of the div matches “aspect.browseArtifacts.CommunityBrowse.list.community-browse”
- I checked the DRI of a community page on my local 6.x and DSpace Test 5.x by appending
?XML to the URL and I see the ID is missing on DSpace 5.x
- The issue is the same with the ordering of the “My Account” link, but in Navigation.java
- I tried modifying
preprocess/browse.xsl but it always ends up printing some default list of browse by links…
- I’m starting to wonder if Atmire’s modules somehow override this, as I don’t see how
CommunityBrowse.java can behave like ours on DSpace 5.x unless they have overridden it (as the open source code is the same in 5.x and 6.x)
- At least the “account” link in the sidebar is overridden in our 5.x branch because Atmire copied a modified
Navigation.java to the local xmlui modules folder… so that explains that (and it’s easy to replicate in 6.x)
2020-02-05
- UptimeRobot told me that AReS Explorer crashed last night, so I logged into it, ran all updates, and rebooted it
- Testing Discovery indexing speed on my local DSpace 6.3:
$ time schedtool -D -e ~/dspace63/bin/dspace index-discovery -b
schedtool -D -e ~/dspace63/bin/dspace index-discovery -b 3771.78s user 93.63s system 41% cpu 2:34:19.53 total

schedtool -D -e ~/dspace63/bin/dspace index-discovery -b 3334.19s user 86.54s system 35% cpu 2:41:56.73 total
- DSpace 5.8 was taking about 1 hour (or less on this laptop), so this is 2-3 times longer!
$ time schedtool -D -e ~/dspace/bin/dspace index-discovery -b

- Checking out the DSpace 6.x REST API query client
- There is a tutorial that explains how it works and I see it is very powerful because you can export a CSV of results in order to fix and re-upload them with batch import!
- Custom queries can be added in
dspace-rest/src/main/webapp/static/reports/restQueryReport.js
- I noticed two new bots in the logs with the following user agents:
Jersey/2.6 (HttpUrlConnection 1.8.0_152)magpie-crawler/1.1 (U; Linux amd64; en-GB; +http://www.brandwatch.net)
- I filed an issue to add Jersey to the COUNTER-Robots list
- Peter noticed that the statlets on community, collection, and item pages aren’t working on CGSpace
- I thought it might be related to the fact that the yearly sharding didn’t complete successfully this year so the
statistics-2019 core is empty
- I removed the
statistics-2019 core and had to restart Tomcat like six times before all cores would load properly (ugh!!!!)
- After that the statlets were working properly…
- Run all system updates on DSpace Test (linode19) and restart it
2020-02-06
- I sent a mail to the dspace-tech mailing list asking about slow Discovery indexing speed in DSpace 6
- I destroyed my PostgreSQL 9.6 containers and re-created them using PostgreSQL 10 to see if there are any speedups with DSpace 6.x:
$ podman pull postgres:10-alpine
$ podman run --name dspacedb10 -v dspacedb_data:/var/lib/postgresql/data -e POSTGRES_PASSWORD=postgres -p 5432:5432 -d postgres:10-alpine
$ createuser -h localhost -U postgres --pwprompt dspacetest
$ createdb -h localhost -U postgres -O dspacetest --encoding=UNICODE dspacetest
$ createdb -h localhost -U postgres -O dspacetest --encoding=UNICODE dspace63
$ psql -h localhost -U postgres -c 'alter user dspacetest superuser;'
$ pg_restore -h localhost -U postgres -d dspacetest -O --role=dspacetest -h localhost ~/Downloads/cgspace_2020-02-06.backup
$ pg_restore -h localhost -U postgres -d dspace63 -O --role=dspacetest -h localhost ~/Downloads/cgspace_2020-02-06.backup

dspace63=# DELETE FROM schema_version WHERE version IN ('5.0.2015.01.27', '5.6.2015.12.03.2', '5.6.2016.08.08', '5.0.2017.04.28', '5.0.2017.09.25', '5.8.2015.12.03.3');
dspace63=# DROP VIEW eperson_metadata;
dspace63=# \q
- I purged ~33,000 hits from the “Jersey/2.6” bot in CGSpace’s statistics using my
check-spider-hits.sh script:
$ ./check-spider-hits.sh -d -p -f /tmp/jersey -s statistics -u http://localhost:8081/solr
$ for year in 2018 2017 2016 2015; do ./check-spider-hits.sh -d -p -f /tmp/jersey -s "statistics-${year}" -u http://localhost:8081/solr; done
- I noticed another user agen in the logs that we should add to the list:
ReactorNetty/0.9.2.RELEASE
$ ./run.sh -s http://localhost:8081/solr/statistics -a export -o /tmp/statistics-2019-01.json -f 'dateYearMonth:2019-01' -k uid
$ ls -lh /tmp/statistics-2019-01.json
-rw-rw-r-- 1 aorth aorth 3.7G Feb 6 09:26 /tmp/statistics-2019-01.json
- Then I tested importing this by creating a new core in my development environment:
$ curl 'http://localhost:8080/solr/admin/cores?action=CREATE&name=statistics-2019&instanceDir=/home/aorth/dspace/solr/statistics&dataDir=/home/aorth/dspace/solr/statistics-2019/data'
$ ./run.sh -s http://localhost:8080/solr/statistics-2019 -a import -o ~/Downloads/statistics-2019-01.json -k uid
- This imports the records into the core, but DSpace can’t see them, and when I restart Tomcat the core is not seen by Solr…
- I got the core to load by adding it to
dspace/solr/solr.xml manually, ie:
<cores adminPath="/admin/cores">
...
<core name="statistics" instanceDir="statistics" />
<core name="statistics-2019" instanceDir="statistics">
<property name="dataDir" value="/home/aorth/dspace/solr/statistics-2019/data" />
</core>
...
</cores>
- But I don’t like having to do that… why doesn’t it load automatically?
- I sent a mail to the dspace-tech mailing list to ask about it
- Just for fun I tried to load these stats into a Solr 7.7.2 instance using the DSpace 7 solr config:
- First, create a Solr statistics core using the DSpace 7 config:
$ ./bin/solr create_core -c statistics -d ~/src/git/DSpace/dspace/solr/statistics/conf -p 8983
- Then try to import the stats, skipping a shitload of fields that are apparently added to our Solr statistics by Atmire modules:
$ ./run.sh -s http://localhost:8983/solr/statistics -a import -o ~/Downloads/statistics-2019-01.json -k uid -S author_mtdt,author_mtdt_search,iso_mtdt_search,iso_mtdt,subject_mtdt,subject_mtdt_search,containerCollection,containerCommunity,containerItem,countryCode_ngram,countryCode_search,cua_version,dateYear,dateYearMonth,geoipcountrycode,ip_ngram,ip_search,isArchived,isInternal,isWithdrawn,containerBitstream,file_id,referrer_ngram,referrer_search,userAgent_ngram,userAgent_search,version_id,complete_query,complete_query_search,filterquery,ngram_query_search,ngram_simplequery_search,simple_query,simple_query_search,range,rangeDescription,rangeDescription_ngram,rangeDescription_search,range_ngram,range_search,actingGroupId,actorMemberGroupId,bitstreamCount,solr_update_time_stamp,bitstreamId
- OK that imported! I wonder if it works… maybe I’ll try another day
2020-02-07
- I did some investigation into DSpace indexing performance using flame graphs
$ cd ~/src/git/perf-map-agent
$ cmake .
$ make
$ ./bin/create-links-in ~/.local/bin
$ export FLAMEGRAPH_DIR=/home/aorth/src/git/FlameGraph
$ export JAVA_HOME=/usr/lib/jvm/java-8-openjdk
$ export JAVA_OPTS="-XX:+PreserveFramePointer"
$ ~/dspace63/bin/dspace index-discovery -b &
# pid of tomcat java process
$ perf-java-flames 4478
# pid of java indexing process
$ perf-java-flames 11359
- All Java processes need to have
-XX:+PreserveFramePointer if you want to trace their methods
- I did the same tests against DSpace 5.8 and 6.4-SNAPSHOT’s CLI indexing process and Tomcat process
- For what it’s worth, it appears all the Hibernate stuff is in the CLI processes, so we don’t need to trace the Tomcat process
- Here is the flame graph for DSpace 5.8’s
dspace index-discovery -b java process:
- Here is the flame graph for DSpace 6.4-SNAPSHOT’s
dspace index-discovery -b java process:
- If the width of the stacks indicates time, then it’s clear that Hibernate takes longer…
- Apparently there is a “flame diff” tool, I wonder if we can use that to compare!
2020-02-09
- This weekend I did a lot more testing of indexing performance with our DSpace 5.8 branch, vanilla DSpace 5.10, and vanilla DSpace 6.4-SNAPSHOT:
# CGSpace 5.8
schedtool -D -e ~/dspace/bin/dspace index-discovery -b 385.72s user 131.16s system 19% cpu 43:21.18 total

schedtool -D -e ~/dspace63/bin/dspace index-discovery -b 5112.96s user 127.80s system 40% cpu 3:21:0.0 total
- I generated better flame graphs for the DSpace indexing process by using
perf-record-stack and filtering out the java process:
$ export JAVA_HOME=/usr/lib/jvm/java-8-openjdk
$ export PERF_RECORD_SECONDS=60
$ export JAVA_OPTS="-XX:+PreserveFramePointer"
$ time schedtool -D -e ~/dspace/bin/dspace index-discovery -b &
# process id of java indexing process (not Tomcat)
$ perf-java-record-stack 169639
$ sudo perf script -i /tmp/perf-169639.data > out.dspace510-1
$ cat out.dspace510-1 | ../FlameGraph/stackcollapse-perf.pl | grep -E '^java' | ../FlameGraph/flamegraph.pl --color=java --hash > out.dspace510-1.svg
- All data recorded on my laptop with the same kernel, same boot, etc.
- CGSpace 5.8 (with Atmire patches):
- Vanilla DSpace 6.4-SNAPSHOT:
- I sent my feedback to the dspace-tech mailing list so someone can hopefully comment.
- Last week Peter asked Sisay to upload some items to CGSpace in the GENNOVATE collection (part of Gender CRP)
2020-02-10
2020-02-11
- Maria from Bioversity asked me to add some ORCID iDs to our controlled vocabulary so I combined them with our existing ones and updated the names from the ORCID API:
$ cat ~/src/git/DSpace/dspace/config/controlled-vocabularies/cg-creator-id.xml /tmp/bioversity-orcid-ids.txt | grep -oE '[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{4}' | sort | uniq > /tmp/2020-02-11-combined-orcids.txt
$ ./resolve-orcids.py -i /tmp/2020-02-11-combined-orcids.txt -o /tmp/2020-02-11-combined-names.txt -d
# sort names, copy to cg-creator-id.xml, add XML formatting, and then format with tidy (preserving accents)
$ tidy -xml -utf8 -iq -m -w 0 dspace/config/controlled-vocabularies/cg-creator-id.xml
- Then I noticed some author names had changed, so I captured the old and new names in a CSV file and fixed them using
fix-metadata-values.py:
$ ./fix-metadata-values.py -i 2020-02-11-correct-orcid-ids.csv -db dspace -u dspace -p 'fuuu' -f cg.creator.id -t correct -m 240 -d
- On a hunch I decided to try to add these ORCID iDs to existing items that might not have them yet
- I checked the database for likely matches to the author name and then created a CSV with the author names and ORCID iDs:
dc.contributor.author,cg.creator.id
"Staver, Charles",charles staver: 0000-0002-4532-6077
