Add dc.type to the output options for Atmire's Listings and Reports module (#286)

2016-11-02

Migrate DSpace Test to DSpace 5.5 (notes)
Run all updates on DSpace Test and reboot the server
Looks like the OAI bug from DSpace 5.1 that caused validation at Base Search to fail is now fixed and DSpace Test passes validation! (#63)
Indexing Discovery on DSpace Test took 332 minutes, which is like five times as long as it usually takes
At the end it appeared to finish correctly but there were lots of errors right after it finished:

DSpace is still up, and a few minutes later I see the default DSpace indexer is still running
Sure enough, looking back before the first one finished, I see output from both indexers interleaved in the log:

I will raise a ticket with Atmire to ask them

After re-deploying and re-indexing I didn't see the same issue, and the indexing completed in 85 minutes, which is about how long it is supposed to take

2016-11-07

Horrible one liner to get Linode ID from certain Ansible host vars:

$ grep -A 3 contact_info * | grep -E "(Orth|Sisay|Peter|Daniel|Tsega)" | awk -F'-' '{print $1}' | grep linode | uniq | xargs grep linode_id

I noticed some weird CRPs in the database, and they don't show up in Discovery for some reason, perhaps the :
I'll export these and fix them in batch:

dspace=# \copy (select distinct text_value, count(*) from metadatavalue where metadata_field_id=230 group by text_value order by count desc) to /tmp/crp.csv with csv;
COPY 22

Test running the replacements:

$ ./fix-metadata-values.py -i /tmp/CRPs.csv -f cg.contributor.crp -t correct -m 230 -d dspace -u dspace -p 'fuuu'

Add AMR to ILRI subjects and remove one duplicate instance of IITA in author affiliations controlled vocabulary (#288)

2016-11-08

Atmire's Listings and Reports module seems to be broken on DSpace 5.5

I've filed a ticket with Atmire
Thinking about batch updates for ORCIDs and authors
Playing with SolrClient in Python to query Solr
All records in the authority core are either authority_type:orcid or authority_type:person
There is a deleted field and all items seem to be false, but might be important sanity check to remember
The way to go is probably to have a CSV of author names and authority IDs, then to batch update them in PostgreSQL
Dump of the top ~200 authors in CGSpace:

dspace=# \copy (select distinct text_value, count(*) from metadatavalue where metadata_field_id=3 group by text_value order by count desc limit 210) to /tmp/210-authors.csv with csv;

2016-11-09

CGSpace crashed so I quickly ran system updates, applied one or two of the waiting changes from the 5_x-prod branch, and rebooted the server
The error was Timeout waiting for idle object but I haven't looked into the Tomcat logs to see what happened
Also, I ran the corrections for CRPs from earlier this week

2016-11-10

Helping Megan Zandstra and CIAT with some questions about the REST API
Playing with find-by-metadata-field, this works:

$ curl -s -H "accept: application/json" -H "Content-Type: application/json" -X POST "http://localhost:8080/rest/items/find-by-metadata-field" -d '{"key": "cg.subject.ilri","value": "SEEDS"}'

But the results are deceiving because metadata fields can have text languages and your query must match exactly!

dspace=# select distinct text_value, text_lang from metadatavalue where resource_type_id=2 and metadata_field_id=203 and text_value='SEEDS';
 text_value | text_lang
------------+-----------
 SEEDS      |
 SEEDS      |
 SEEDS      | en_US
(3 rows)

So basically, the text language here could be null, blank, or en_US
To query metadata with these properties, you can do:

$ curl -s -H "accept: application/json" -H "Content-Type: application/json" -X POST "http://localhost:8080/rest/items/find-by-metadata-field" -d '{"key": "cg.subject.ilri","value": "SEEDS"}' | jq length
55
$ curl -s -H "accept: application/json" -H "Content-Type: application/json" -X POST "http://localhost:8080/rest/items/find-by-metadata-field" -d '{"key": "cg.subject.ilri","value": "SEEDS", "language":""}' | jq length
34
$ curl -s -H "accept: application/json" -H "Content-Type: application/json" -X POST "http://localhost:8080/rest/items/find-by-metadata-field" -d '{"key": "cg.subject.ilri","value": "SEEDS", "language":"en_US"}' | jq length

The results (55+34=89) don't seem to match those from the database:

dspace=# select count(text_value) from metadatavalue where resource_type_id=2 and metadata_field_id=203 and text_value='SEEDS' and text_lang is null;
 count
-------
    15
dspace=# select count(text_value) from metadatavalue where resource_type_id=2 and metadata_field_id=203 and text_value='SEEDS' and text_lang='';
 count
-------
     4
dspace=# select count(text_value) from metadatavalue where resource_type_id=2 and metadata_field_id=203 and text_value='SEEDS' and text_lang='en_US';
 count
-------
    66

So, querying from the API I get 55 + 34 = 89 results, but the database actually only has 85...
And the find-by-metadata-field endpoint doesn't seem to have a way to get all items with the field, or a wildcard value
I'll ask a question on the dspace-tech mailing list
And speaking of text_lang, this is interesting:

dspacetest=# select distinct text_lang from metadatavalue where resource_type_id=2;
 text_lang
-----------

 ethnob
 en
 spa
 EN
 es
 frn
 en_
 en_US

 EN_US
 eng
 en_U
 fr
(14 rows)

Generate a list of all these so I can maybe fix them in batch:

dspace=# \copy (select distinct text_lang, count(*) from metadatavalue where resource_type_id=2 group by text_lang order by count desc) to /tmp/text-langs.csv with csv;
COPY 14

Perhaps we need to fix them all in batch, or experiment with fixing only certain metadatavalues:

dspace=# update metadatavalue set text_lang='en_US' where resource_type_id=2 and metadata_field_id=203 and text_value='SEEDS';
UPDATE 85

The fix-metadata.py script I have is meant for specific metadata values, so if I want to update some text_lang values I should just do it directly in the database
For example, on a limited set:

dspace=# update metadatavalue set text_lang=NULL where resource_type_id=2 and metadata_field_id=203 and text_value='LIVESTOCK' and text_lang='';
UPDATE 420

And assuming I want to do it for all fields:

dspacetest=# update metadatavalue set text_lang=NULL where resource_type_id=2 and text_lang='';
UPDATE 183726

After that restarted Tomcat and PostgreSQL (because I'm superstitious about caches) and now I see the following in REST API query:

$ curl -s -H "accept: application/json" -H "Content-Type: application/json" -X POST "http://localhost:8080/rest/items/find-by-metadata-field" -d '{"key": "cg.subject.ilri","value": "SEEDS"}' | jq length
71
$ curl -s -H "accept: application/json" -H "Content-Type: application/json" -X POST "http://localhost:8080/rest/items/find-by-metadata-field" -d '{"key": "cg.subject.ilri","value": "SEEDS", "language":""}' | jq length
0
$ curl -s -H "accept: application/json" -H "Content-Type: application/json" -X POST "http://localhost:8080/rest/items/find-by-metadata-field" -d '{"key": "cg.subject.ilri","value": "SEEDS", "language":"en_US"}' | jq length

Not sure what's going on, but Discovery shows 83 values, and database shows 85, so I'm going to reindex Discovery just in case

I applied Atmire's suggestions to fix Listings and Reports for DSpace 5.5 and now it works
There were some issues with the dspace/modules/jspui/pom.xml, which is annoying because all I did was rebase our working 5.1 code on top of 5.5, meaning Atmire's installation procedure must have changed
So there is apparently this Tomcat native way to limit web crawlers to one session: Crawler Session Manager
After adding that to server.xml bots matching the pattern in the configuration will all use ONE session, just like normal users:

$ http --print h https://dspacetest.cgiar.org 'User-Agent:Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)'
HTTP/1.1 200 OK

The first one gets a session, and any after that — within 60 seconds — will be internally mapped to the same session by Tomcat
This means that when Google or Baidu slam you with tens of concurrent connections they will all map to ONE internal session, which saves RAM!

2016-11-15

The Tomcat JVM heap looks really good after applying the Crawler Session Manager fix on DSpace Test last night:

Seems the default regex doesn't catch Baidu, though:

$ http --print h https://dspacetest.cgiar.org 'User-Agent:Mozilla/5.0 (compatible; Baiduspider/2.0; +http://www.baidu.com/search/spider.html)'

Adding Baiduspider to the list of user agents seems to work, and the final configuration should be:

<!-- Crawler Session Manager Valve helps mitigate damage done by web crawlers -->
<Valve className="org.apache.catalina.valves.CrawlerSessionManagerValve"
       crawlerUserAgents=".*[bB]ot.*|.*Yahoo! Slurp.*|.*Feedfetcher-Google.*|.*Baiduspider.*" />

Looking at the bots that were active yesterday it seems the above regex should be sufficient:

$ grep -o -E 'Mozilla/5\.0 \(compatible;.*\"' /var/log/nginx/access.log | sort | uniq
Mozilla/5.0 (compatible; Baiduspider/2.0; +http://www.baidu.com/search/spider.html)" "-"

Mozilla/5.0 (compatible; YandexBot/3.0; +http://yandex.com/bots)" "-"
Mozilla/5.0 (compatible; YandexImages/3.0; +http://yandex.com/bots)" "-"

Neat maven trick to exclude some modules from being built:

$ mvn -U -Dmirage2.on=true -Dmirage2.deps.included=false -Denv=localhost -P \!dspace-lni,\!dspace-rdf,\!dspace-sword,\!dspace-swordv2 clean package

We absolutely don't use those modules, so we shouldn't build them in the first place

Generate a list of journal titles for Peter and Abenet to look through so we can make a controlled vocabulary out of them:

dspace=# \copy (select distinct text_value, count(*) from metadatavalue where resource_type_id=2 and metadata_field_id=55 group by text_value order by count desc) to /tmp/journal-titles.csv with csv;
COPY 2515

Send a message to users of the CGSpace REST API to notify them of upcoming upgrade so they can test their apps against DSpace Test
Test an update old, non-HTTPS links to the CCAFS website in CGSpace metadata:

dspacetest=# update metadatavalue set text_value = regexp_replace(text_value, 'http://ccafs.cgiar.org','https://ccafs.cgiar.org') where resource_type_id=2 and text_value like '%http://ccafs.cgiar.org%';
UPDATE 164
dspace=# update metadatavalue set text_value = regexp_replace(text_value, 'http://ccafs.cgiar.org','https://ccafs.cgiar.org') where resource_type_id=2 and text_value like '%http://ccafs.cgiar.org%';
UPDATE 7

Had to run it twice to get all (not sure about "global" regex in PostgreSQL)
Run the updates on CGSpace as well
Run through some collections and manually regenerate some PDF thumbnails for items from before 2016 on DSpace Test to compare with CGSpace
I'm debating forcing the re-generation of ALL thumbnails, since some come from DSpace 3 and 4 when the thumbnailing wasn't as good
The results were very good, I think that after we upgrade to 5.5 I will do it, perhaps one community / collection at a time:

$ [dspace]/bin/dspace filter-media -f -i 10568/67156 -p "ImageMagick PDF Thumbnail"

In related news, I'm looking at thumbnails of thumbnails (the ones we uploaded manually before, and now DSpace's media filter has made thumbnails of THEM):

dspace=# select text_value from metadatavalue where text_value like '%.jpg.jpg';

I'm not sure if there's anything we can do, actually, because we would have to remove those from the thumbnail bundles, and replace them with the regular JPGs from the content bundle, and then remove them from the assetstore...

Enable Tomcat Crawler Session Manager on CGSpace

2016-11-21

More work on Ansible playbooks for PostgreSQL 9.3→9.5 and Java 7→8 work
CGSpace virtual managers meeting
I need to look into making the item thumbnail clickable
Macaroni Bros said they tested the DSpace Test (DSpace 5.5) REST API for CCAFS and WLE sites and it works as expected

2016-11-23

Upgrade Java from 7 to 8 on CGSpace
I had started planning the inplace PostgreSQL 9.3→9.5 upgrade but decided that I will have to pg_dump and pg_restore when I move to the new server soon anyways, so there's no need to upgrade the database right now
Chat with Carlos about CGCore and the CGSpace metadata registry
Dump CGSpace metadata field registry for Carlos: https://gist.github.com/alanorth/8cbd0bb2704d4bbec78025b4742f8e70
Send some feedback to Carlos on CG Core so they can better understand how DSpace/CGSpace uses metadata

Play with Creative Commons stuff in DSpace submission step
It seems to work but it doesn't let you choose a version of CC (like 4.0), and we would need to customize the XMLUI item display so it doesn't display the gross CC badges

2016-11-24

Bizuwork was testing DSpace Test on DSPace 5.5 and noticed that the Listings and Reports module seems to be case sensitive, whereas CGSpace's Listings and Reports isn't (ie, a search for "orth, alan" vs "Orth, Alan" returns the same results on CGSpace, but different on DSpace Test)
I have raised a ticket with Atmire
Looks like this issue is actually the new Listings and Reports module honoring the Solr search queries more correctly

2016-11-27

Run system updates on DSpace Test and reboot the server
Deploy DSpace 5.5 on CGSpace:
- maven package
- stop tomcat
- backup postgresql
- run Atmire 5.5 schema deletions
- delete the deployed spring folder
- ant update
- run system updates
- reboot server
Need to do updates for ansible infrastructure role defaults, and switch the GitHub branch to the new 5.5 one
Testing DSpace 5.5 on CGSpace, it seems CUA's export as XLS works for Usage statistics, but not Content statistics
I will raise a bug with Atmire

One user says they are still getting a blank page when he logs in (just CGSpace header, but no community list)
Looking at the Catlina logs I see there is some super long-running indexing process going on:

Wow, Bram from Atmire pointed out this solution for using multiple handles with one DSpace instance: https://wiki.lyrasis.org/display/DSDOC5x/Installing+DSpace?focusedCommentId=78163296#comment-78163296
We might be able to migrate the CGIAR Library now, as they had wanted to keep their handles

At about the same time in the solr log I see a super long query:

Which, according to some old threads on DSpace Tech, means that the user has a lot of permissions (from groups or on the individual eperson) which increases the Solr query size / query URL
It might be fixed by increasing the Tomcat maxHttpHeaderSize, which is 8192 (or 8KB) by default
I've increased the maxHttpHeaderSize to 16384 on DSpace Test and the user said he is now able to see the communities on the homepage
I will make the changes on CGSpace soon
A few users are reporting having issues with their workflows, they get the following message: "You are not allowed to perform this task"
Might be the same as DS-2920 on the bug tracker

2016-11-30

The maxHttpHeaderSize fix worked on CGSpace (user is able to see the community list on the homepage)
The "take task" cache fix worked on DSpace Test but it's not an official patch, so I'll have to report the bug to DSpace people and try to get advice
More work on the KM4Dev Journal article
