I wrote a script to query Sherpa's API for our ISSNs: sherpa-issn-lookup.py
- I'm curious to see how the results compare with the results from Crossref yesterday
AReS Explorer was down since this morning, I didn't see anything in the systemd journal
- I simply took everything down with docker-compose and then back up, and then it was OK
- Perhaps one of the containers crashed, I should have looked closer but I was in a hurry

2021-04-03

Biruk from ICT contacted me to say that some CGSpace users still can't log in
- I guess the CGSpace LDAP bind account is really still locked after last week's reset
- He fixed the account and then I was finally able to bind and query:

$ ldapsearch -x -H ldaps://AZCGNEROOT2.CGIARAD.ORG:636/ -b "dc=cgiarad,dc=org" -D "cgspace-account" -W "(sAMAccountName=otheraccounttoquery)"

Check the index aliases on AReS Explorer to make sure they are sane before starting a new harvest:

$ curl -s 'http://localhost:9200/_alias/' | python -m json.tool | less

Then set the openrxv-items-final index to read-only so we can make a backup:

$ curl -X PUT "localhost:9200/openrxv-items-final/_settings" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": true}}' 
{"acknowledged":true}%
$ curl -s -X POST http://localhost:9200/openrxv-items-final/_clone/openrxv-items-final-backup
{"acknowledged":true,"shards_acknowledged":true,"index":"openrxv-items-final-backup"}%
$ curl -X PUT "localhost:9200/openrxv-items-final/_settings" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": false}}'

Then start a harvesting on AReS Explorer
Help Enrico get some 2020 statistics for the Roots, Tubers and Bananas (RTB) community on CGSpace
- He was hitting a bug on AReS and also he only needed stats for 2020, and AReS currently only gives all-time stats
I cleaned up about 230 ISSNs on CGSpace in OpenRefine
- I had exported them last week, then filtered for anything not looking like an ISSN with this GREL: isNotNull(value.match(/^\p{Alnum}{4}-\p{Alnum}{4}$/))
- Then I applied them on CGSpace with the fix-metadata-values.py script:

$ ./ilri/fix-metadata-values.py -i /tmp/2021-04-01-ISSNs.csv -db dspace -u dspace -p 'fuuu' -f cg.issn -t 'correct' -m 253

For now I only fixed obvious errors like "1234-5678." and "e-ISSN: 1234-5678" etc, but there are still lots of invalid ones which need more manual work:
- Too few characters
- Too many characters
- ISBNs
Create the CGSpace community and collection structure for the new Accelerating Impacts of CGIAR Climate Research for Africa (AICCRA) and assign all workflow steps

2021-04-05

The AReS Explorer harvesting from yesterday finished, and the results look OK, but actually the Elasticsearch indexes are messed up again:

$ curl -s 'http://localhost:9200/_alias/' | python -m json.tool
{
    "openrxv-items-final": {
        "aliases": {}
    },
    "openrxv-items-temp": {
        "aliases": {
            "openrxv-items": {}
        }
    },
...
}

openrxv-items should be an alias of openrxv-items-final, not openrxv-temp... I will have to fix that manually
Enrico asked for more information on the RTB stats I gave him yesterday
- I remembered (again) that we can't filter Atmire's CUA stats by date issued
- To show, for example, views/downloads in the year 2020 for RTB issued in 2020, we would need to use the DSpace statistics API and post a list of IDs and a custom date range
- I tried to do that here by exporting the RTB community and extracting the IDs for items issued in 2020:

$ ~/dspace63/bin/dspace metadata-export -i 10568/80100 -f /tmp/rtb.csv
$ csvcut -c 'id,dcterms.issued,dcterms.issued[],dcterms.issued[en_US]' /tmp/rtb.csv | \
  sed '1d' | \
  csvsql --no-header --no-inference --query 'SELECT a AS id,COALESCE(b, "")||COALESCE(c, "")||COALESCE(d, "") AS issued FROM stdin' | \
  csvgrep -c issued -m 2020 | \
  csvcut -c id | \
  sed '1d' | \
  sort | \
  uniq

So I remember in the future, this basically does the following:
- Use csvcut to extract the id and all date issued columns from the CSV
- Use sed to remove the header so we can refer to the columns using default a, b, c instead of their real names (which are tricky to match due to special characters)
- Use csvsql to concatenate the various date issued columns (coalescing where null)
- Use csvgrep to filter items by date issued in 2020
- Use csvcut to extract the id column
- Use sed to delete the header row
- Use sort and uniq to filter out any duplicate IDs (there were three)
Then I have a list of 296 IDs for RTB items issued in 2020
I constructed a JSON file to post to the DSpace Statistics API:

{
  "limit": 100,
  "page": 0,
  "dateFrom": "2020-01-01T00:00:00Z",
  "dateTo": "2020-12-31T00:00:00Z",
  "items": [
"00358715-b70c-4fdd-aa55-730e05ba739e",
"004b54bb-f16f-4cec-9fbc-ab6c6345c43d",
"02fb7630-d71a-449e-b65d-32b4ea7d6904",
...
  ]
}

Then I submitted the file three times (changing the page parameter):

$ curl -s -d @/tmp/2020-items.txt https://cgspace.cgiar.org/rest/statistics/items | json_pp > /tmp/page1.json
$ curl -s -d @/tmp/2020-items.txt https://cgspace.cgiar.org/rest/statistics/items | json_pp > /tmp/page2.json
$ curl -s -d @/tmp/2020-items.txt https://cgspace.cgiar.org/rest/statistics/items | json_pp > /tmp/page3.json

Then I extracted the views and downloads in the most ridiculous way:

$ grep views /tmp/page*.json | grep -o -E '[0-9]+$' | sed 's/,//' | xargs | sed -e 's/ /+/g' | bc
30364
$ grep downloads /tmp/page*.json | grep -o -E '[0-9]+,' | sed 's/,//' | xargs | sed -e 's/ /+/g' | bc
9100

For curiousity I did the same exercise for items issued in 2019 and got the following:
- Views: 30721
- Downloads: 10205

2021-04-06

Margarita from CCAFS was having problems deleting an item from CGSpace again
- The error was "Authorization denied for action OBSOLETE (DELETE) on BITSTREAM:bd157345-448e ..."
- This is the same issue as last month
Create a new collection on CGSpace for a new CIP project at Mishel Portilla's request
I got a notice that CGSpace was down
- I didn't see anything strange at first, but there are an insane amount of database connections:

$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
12413

The system journal shows thousands of these messages in the system journal, this is the first one:

Apr 06 07:52:13 linode18 tomcat7[556]: Apr 06, 2021 7:52:13 AM org.apache.tomcat.jdbc.pool.ConnectionPool abandon

Around that time in the dspace log I see nothing unusual, but maybe these?

2021-04-06 07:52:29,409 INFO  com.atmire.dspace.cua.CUASolrLoggerServiceImpl @ Updating : 200/127 docs in http://localhost:8081/solr/statistics

(BTW what is the deal with the "200/127"? I should send a comment to Atmire)
- I file a ticket with Atmire: https://tracker.atmire.com/tickets-cgiar-ilri/view-tickets
I restarted the PostgreSQL and Tomcat services and now I see less connections, but still WAY high:

$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
3640
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
2968
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
13

After ten minutes or so it went back down...
And now it's back up in the thousands... I am seeing a lot of stuff in dspace log like this:

I sent some notes and a log to Atmire on our existing issue about the database stuff
- Also I asked them about the possibility of doing a formal review of Hibernate
Falcon 3.0.0 was released so I updated the 3.0.0 branch for dspace-statistics-api and merged it to v6_x
- I also fixed one minor (unrelated) bug in the tests
- Then I deployed the new version on DSpace Test
I had a meeting with Peter and Abenet about CGSpace TODOs
CGSpace went down again and the PostgreSQL locks are through the roof:

$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
12154

I don't see any activity on REST API, but in the last four hours there have been 3,500 DSpace sessions:

# grep -a -E '2021-04-06 (13|14|15|16|17):' /home/cgspace.cgiar.org/log/dspace.log.2021-04-06 | grep -o -E 'session_id=[A-Z0-9]{32}' | sort | uniq | wc -l
3547

I looked at the same time of day for the past few weeks and it seems to be a normal number of sessions:

# for file in /home/cgspace.cgiar.org/log/dspace.log.2021-0{3,4}-*; do grep -a -E "2021-0(3|4)-[0-9]{2} (13|14|15|16|17):" "$file" | grep -o -E 'session_id=[A-Z0-9]{32}' | sort | uniq | wc -l; done

What about total number of sessions per day?

# for file in /home/cgspace.cgiar.org/log/dspace.log.2021-0{3,4}-*; do echo "$file:"; grep -a -o -E 'session_id=[A-Z0-9]{32}' "$file" | sort | uniq | wc -l; done

So it's not the number of sessions... it's something with the workload...
I had to step away for an hour or so and when I came back the site was still down and there were still 12,000 locks
- I restarted postgresql and tomcat7...
The locks in PostgreSQL shot up again...

$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
3447
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
3527
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
4582

I don't know what the hell is going on, but the PostgreSQL connections and locks are way higher than ever before:

Otherwise, the number of DSpace sessions is completely normal:

While looking at the nginx logs I see that MEL is trying to log into CGSpace's REST API and delete items:

34.209.213.122 - - [06/Apr/2021:03:50:46 +0200] "POST /rest/login HTTP/1.1" 401 727 "-" "MEL"

I see a few of these per day going back several months
- I sent a message to Salem and Enrico to ask if they know
Also annoying, I see tons of what look like penetration testing requests from Qualys:

I deleted the ilri/AReS repository on GitHub since we haven't updated it in two years
- All development is happening in https://github.com/ilri/openRXV now
10PM and the server is down again, with locks through the roof:

$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
12198

I see that there are tons of PostgreSQL connections getting abandoned today, compared to very few in the past few weeks:

$ journalctl -u tomcat7 --since=today | grep -c 'ConnectionPool abandon'
1838
$ journalctl -u tomcat7 --since=2021-03-20 --until=2021-04-05 | grep -c 'ConnectionPool abandon'
3

I even restarted the server and connections were low for a few minutes until they shot back up:

$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
13
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
8651
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
8940
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
10504

I had to go to bed and I bet it will crash and be down for hours until I wake up...
What the hell is this user agent?

CGSpace was still down from last night of course, with tons of database locks:

$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
12168

I restarted the server again and the locks came back
Atmire responded to the message from yesterday
- The noticed something in the logs about emails failing to be sent
- There appears to be an issue sending mails on workflow tasks when a user in that group has an invalid email address:

The issue is not the named user above, but a member of the group...
And the group does have users with invalid email addresses (probably accounts created automatically after authenticating with LDAP):

I extracted all the group IDs from recent logs that had users with invalid email addresses:

$ grep -a -E 'email user group_id=\b[0-9a-f]{8}\b-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-\b[0-9a-f]{12}\b' /home/cgspace.cgiar.org/log/dspace.log.* | grep -o -E '\b[0-9a-f]{8}\b-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-\b[0-9a-f]{12}\b' | sort | uniq

I can't believe it but the server has been down for twelve hours or so
- The locks have not changed since I went to bed last night:

$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
12070

I restarted PostgreSQL and Tomcat and the locks go straight back up!

$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
13
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l

Atmire managed to get CGSpace back up by killing all the PostgreSQL connections yesterday
- I don't know how they did it...
- They also think it's weird that restarting PostgreSQL didn't kill the connections
- They asked some more questions, like for example if there were also issues on DSpace Test
- Strangely enough, I checked DSpace Test and notice a clear spike in PostgreSQL locks on the morning of April 6th as well!

I definitely need to look into that!

2021-04-11

I am trying to resolve the AReS Elasticsearch index issues that happened last week
- I decided to back up the openrxv-items index to openrxv-items-backup and then delete all the others:

$ curl -X PUT "localhost:9200/openrxv-items/_settings" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": true}}'
$ curl -s -X POST http://localhost:9200/openrxv-items-temp/_clone/openrxv-items-backup
$ curl -X PUT "localhost:9200/openrxv-items/_settings" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": false}}'
$ curl -XDELETE 'http://localhost:9200/openrxv-items-temp'
$ curl -XDELETE 'http://localhost:9200/openrxv-items-final'

Then I updated all Docker containers and rebooted the server (linode20) so that the correct indexes would be created again:

$ docker images | grep -v ^REPO | sed 's/ \+/:/g' | cut -d: -f1,2 | xargs -L1 docker pull

Then I realized I have to clone the backup index directly to openrxv-items-final, and re-create the openrxv-items alias:

$ curl -XDELETE 'http://localhost:9200/openrxv-items-final'
$ curl -X PUT "localhost:9200/openrxv-items-backup/_settings" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": true}}'
$ curl -s -X POST http://localhost:9200/openrxv-items-backup/_clone/openrxv-items-final
$ curl -s -X POST 'http://localhost:9200/_aliases' -H 'Content-Type: application/json' -d'{"actions" : [{"add" : { "index" : "openrxv-items-final", "alias" : "openrxv-items"}}]}'

Now I see both openrxv-items-final and openrxv-items have the current number of items:

$ curl -s 'http://localhost:9200/openrxv-items/_count?q=*&pretty'     
{
  "count" : 103373,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  }
}
$ curl -s 'http://localhost:9200/openrxv-items-final/_count?q=*&pretty'
{
  "count" : 103373,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  }
}

Then I started a fresh harvesting in the AReS Explorer admin dashboard

2021-04-12

The harvesting on AReS finished last night, but the indexes got messed up again
- I will have to fix them manually next time...

2021-04-13

Looking into the logs on 2021-04-06 on CGSpace and DSpace Test to see if there is anything specific that stands out about the activty on those days that would cause the PostgreSQL issues
- Digging into the Munin graphs for the last week I found a few other things happening on that morning:

13,000 requests in the last two months from a user with user agent SomeRandomText, for example:

84.33.2.97 - - [06/Apr/2021:06:25:13 +0200] "GET /bitstream/handle/10568/77776/CROP%20SCIENCE.jpg.jpg HTTP/1.1" 404 10890 "-" "SomeRandomText"

I purged them:

$ ./ilri/check-spider-hits.sh -f /tmp/agents.txt -p
Purging 13159 hits from SomeRandomText in statistics

Total number of bot hits purged: 13159

I noticed there were 78 items submitted in the hour before CGSpace crashed:

# grep -a -E '2021-04-06 0(6|7):' /home/cgspace.cgiar.org/log/dspace.log.2021-04-06 | grep -c -a add_item 
78

Of those 78, 77 of them were from Udana
Compared to other mornings (0 to 9 AM) this month that seems to be pretty high:

# for num in {01..13}; do grep -a -E "2021-04-$num 0" /home/cgspace.cgiar.org/log/dspace.log.2021-04-$num | grep -c -a
 add_item; done

2021-04-15

Release v1.4.2 of the DSpace Statistics API on GitHub: https://github.com/ilri/dspace-statistics-api/releases/tag/v1.4.2
- This has been running on DSpace Test for the last week or so, and mostly contains the Falcon 3.0.0 changes
Re-sync DSpace Test with data from CGSpace
- Run system updates on DSpace Test (linode26) and reboot the server
Update the PostgreSQL JDBC driver on DSpace Test (linode26) to 42.2.19
- It has been a few months since we updated this, and there have been a few releases since 42.2.14 that we are currently using
Create a test account for Rafael from Bioversity-CIAT to submit some items to DSpace Test:

$ dspace user -a -m tip-submit@cgiar.org -g CIAT -s Submit -p 'fuuuuuuuu'

I added the account to the Alliance Admins account, which is should allow him to submit to any Alliance collection
- According to my notes from [2020-10]({{< relref "2020-10.md" >}}) the account must be in the admin group in order to submit via the REST API

2021-04-18

Update all containers on AReS (linode20):

$ docker images | grep -v ^REPO | sed 's/ \+/:/g' | cut -d: -f1,2 | xargs -L1 docker pull

Then run all system updates and reboot the server
I learned a new command for Elasticsearch:

$ curl http://localhost:9200/_cat/indices

Somehow the openrxv-items-final index only has a few items and the majority are in openrxv-items-temp, via the openrxv-items alias (which is in the temp index):

$ curl -s 'http://localhost:9200/openrxv-items/_count?q=*&pretty' 
{
  "count" : 103585,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  }
}

I found a cool tool to help with exporting and restoring Elasticsearch indexes:

$ elasticdump --input=http://localhost:9200/openrxv-items --output=/home/aorth/openrxv-items_mapping.json --type=mapping
$ elasticdump --input=http://localhost:9200/openrxv-items --output=/home/aorth/openrxv-items_data.json --limit=1000 --type=data
...
Sun, 18 Apr 2021 06:27:07 GMT | Total Writes: 103585
Sun, 18 Apr 2021 06:27:07 GMT | dump complete

It took only two or three minutes to export everything...
I did a test to restore the index:

$ elasticdump --input=/home/aorth/openrxv-items_mapping.json --output=http://localhost:9200/openrxv-items-test --type=mapping
$ elasticdump --input=/home/aorth/openrxv-items_data.json --output=http://localhost:9200/openrxv-items-test --limit 1000 --type=data

So that's pretty cool!
I deleted the openrxv-items-final index and openrxv-items-temp indexes and then restored the mappings to openrxv-items-final, added the openrxv-items alias, and started restoring the data to openrxv-items with elasticdump:

$ curl -XDELETE 'http://localhost:9200/openrxv-items-final'
$ elasticdump --input=/home/aorth/openrxv-items_mapping.json --output=http://localhost:9200/openrxv-items-final --type=mapping
$ curl -s -X POST 'http://localhost:9200/_aliases' -H 'Content-Type: application/json' -d'{"actions" : [{"add" : { "index" : "openrxv-items-final", "alias" : "openrxv-items"}}]}'
$ elasticdump --input=/home/aorth/openrxv-items_data.json --output=http://localhost:9200/openrxv-items --limit 1000 --type=data

AReS seems to be working fine аfter that, so I created the openrxv-items-temp index and then started a fresh harvest on AReS Explorer:

$ curl -X PUT "localhost:9200/openrxv-items-temp"

Run system updates on CGSpace (linode18) and run the latest Ansible infrastructure playbook to update the DSpace Statistics API, PostgreSQL JDBC driver, etc, and then reboot the system
I wasted a bit of time trying to get TSLint and then ESLint running for OpenRXV on GitHub Actions

2021-04-19

The AReS harvesting last night seems to have completed successfully, but the number of results is strange:

$ curl -s http://localhost:9200/_cat/indices | grep openrxv-items
yellow open openrxv-items-temp       kNUlupUyS_i7vlBGiuVxwg 1 1 103741 105553 483.6mb 483.6mb
yellow open openrxv-items-final      HFc3uytTRq2GPpn13vkbmg 1 1    970      0   2.3mb   2.3mb

The indices endpoint doesn't include the openrxv-items alias, but it is currently in the openrxv-items-temp index so the number of items is the same:

$ curl -s 'http://localhost:9200/openrxv-items/_count?q=*&pretty'     
{
  "count" : 103741,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  }
}

A user was having problems resetting their password on CGSpace, with some message about SMTP etc
- I checked and we are indeed locked out of our mailbox:

$ dspace test-email
...

I decided to switch back to the G1GC garbage collector on DSpace Test

Send Abdullah feedback on the filter on click pull request for OpenRXV
- I see it adds a new "allow filter on click" checkbox in the layout settings, but it doesn't modify the filters
- Also, it seems to have broken the existing clicking of the countries on the map
Atmire recently sent feedback about the CUA duplicates processor
- Last month when I ran it it got stuck on the storage reports, apparently, so I will try again (with a fresh Solr statistics core from production) and skip the storage reports (-g):

$ export JAVA_OPTS='-Dfile.encoding=UTF-8 -Xmx2048m'
$ cp atmire-cua-update.xml-20210124-132112.old /home/dspacetest.cgiar.org/config/spring/api/atmire-cua-update.xml
$ chrt -b 0 dspace dsrun com.atmire.statistics.util.update.atomic.AtomicStatisticsUpdateCLI -r 100 -c statistics -t 12 -g

The first run processed 1,439 docs, the second run processed 0 docs
- I'm not sure if that means that it worked? I sent feedback to Atmire

The indexes on AReS are messed up again
- I made a backup of the indexes, then deleted the openrxv-items-final and openrxv-items-temp indexes, re-created the openrxv-items alias, and restored the data into openrxv-items:

$ elasticdump --input=http://localhost:9200/openrxv-items --output=/home/aorth/openrxv-items_mapping.json --type=mapping
$ elasticdump --input=http://localhost:9200/openrxv-items --output=/home/aorth/openrxv-items_data.json --limit=1000 --type=data
$ curl -XDELETE 'http://localhost:9200/openrxv-items-temp'
$ curl -XDELETE 'http://localhost:9200/openrxv-items-final'
$ elasticdump --input=/home/aorth/openrxv-items_mapping.json --output=http://localhost:9200/openrxv-items-final --type=mapping
$ curl -s -X POST 'http://localhost:9200/_aliases' -H 'Content-Type: application/json' -d'{"actions" : [{"add" : { "index" : "openrxv-items-final", "alias" : "openrxv-items"}}]}'
$ elasticdump --input=/home/aorth/openrxv-items_data.json --output=http://localhost:9200/openrxv-items --limit 1000 --type=data

Then I started a fresh AReS harvest

2021-04-26

The AReS harvest last night seems to have finished successfully and the number of items looks good:

$ curl -s http://localhost:9200/_cat/indices | grep openrxv-items
yellow open openrxv-items-temp       H-CGsyyLTaqAj6-nKXZ-7w 1 1      0 0    283b    283b
yellow open openrxv-items-final      ul3SKsa7Q9Cd_K7qokBY_w 1 1 103951 0   254mb   254mb

And the aliases seem correct for once:

$ curl -s 'http://localhost:9200/_alias/' | python -m json.tool
...
    "openrxv-items-final": {
        "aliases": {
            "openrxv-items": {}
        }
    },
    "openrxv-items-temp": {
        "aliases": {}
    },
...

That's 250 new items in the index since the last harvest!
Re-create my local Artifactory container because I'm getting errors starting it and it has been a few months since it was updated:

$ podman rm artifactory
$ podman pull docker.bintray.io/jfrog/artifactory-oss:latest
$ podman create --ulimit nofile=32000:32000 --name artifactory -v artifactory_data:/var/opt/jfrog/artifactory -p 8081-8082:8081-8082 docker.bintray.io/jfrog/artifactory-oss
$ podman start artifactory

Start testing DSpace 7.0 Beta 5 so I can evaluate if it solves some of the problems we are having on DSpace 6, and if it's missing things like multiple handle resolvers, etc
- I see it needs Java JDK 11, Tomcat 9, Solr 8, and PostgreSQL 11
- Also, according to the installation notes I see you can install the old DSpace 6 REST API, so that's potentially useful for us
- I see that all web applications on the backend are now rolled into just one "server" application
- The build process took 11 minutes the first time (due to downloading the world with Maven) and ~2 minutes the second time
- The local.cfg content and syntax is very similar DSpace 6
I got the basic fresh_install up and running
- Then I tried to import a DSpace 6 database from production
I tried to delete all the Atmire SQL migrations:

localhost/dspace7b5= > DELETE FROM schema_version WHERE description LIKE '%Atmire%' OR description LIKE '%CUA%' OR description LIKE '%cua%';

But I got an error when running dspace database migrate:

I deleted those migrations:

localhost/dspace7b5= > DELETE FROM schema_version WHERE version IN ('5.0.2017.09.25', '6.0.2017.01.30', '6.0.2017.09.25');

Then when I ran the migration again it failed for a new reason, related to the configurable workflow:

Database URL: jdbc:postgresql://localhost:5432/dspace7b5
Migrating database to latest version... (Check dspace logs for details)
Migration exception:

The DSpace 7 upgrade docs say I need to apply these previously optional migrations:

$ ~/dspace7b5/bin/dspace database migrate ignored

Now I see all migrations have completed and DSpace actually starts up fine!
I will try to do a full re-index to see how long it takes:

$ time ~/dspace7b5/bin/dspace index-discovery -b
...
~/dspace7b5/bin/dspace index-discovery -b  25156.71s user 64.22s system 97% cpu 7:11:09.94 total

Not good, that shit took almost seven hours!

Peter sent me a list of 500+ DOIs from CGSpace with no Altmetric score
- I used csvgrep (with Windows encoding!) to extract those without our handle and save the DOIs to a text file, then got their handles with my doi-to-handle.py script:

$ csvgrep -e 'windows-1252' -c 'Handle.net IDs' -i -m '10568/' ~/Downloads/Altmetric\ -\ Research\ Outputs\ -\ CGSpace\ -\ 2021-04-26.csv | csvcut -c DOI | sed '1d' > /tmp/dois.txt
$ ./ilri/doi-to-handle.py -i /tmp/dois.txt -o /tmp/handles.csv -db dspace63 -u dspace -p 'fuuu' -d

He will Tweet them...
