## 2021-12-01
- Atmire merged some changes I had submitted to the COUNTER-Robots project
- I updated our local spider user agents and then re-ran the list with my `check-spider-hits.sh` script on CGSpace:
```console
$ ./ilri/check-spider-hits.sh -f /tmp/agents -p
Purging 1989 hits from The Knowledge AI in statistics
Purging 1235 hits from MaCoCu in statistics
Purging 455 hits from WhatsApp in statistics
Total number of bot hits purged: 3679
```

## 2021-12-02
- Francesca from Alliance asked me for help with approving a submission that gets stuck
- I looked at the PostgreSQL activity and the locks are back up like they were earlier this week
```console
$ psql -c "SELECT application_name FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid" | sort | uniq -c | sort -n
1
1 ------------------
1 (1437 rows)
1 application_name
9 psql
1428 dspaceWeb
```
- Munin shows the same:
![PostgreSQL locks week](/cgspace-notes/2021/12/postgres_locks_ALL-week.png)
- Last month I enabled the `log_lock_waits` in PostgreSQL so I checked the log and was surprised to find only a few since I restarted PostgreSQL three days ago:
```console
# grep -E '^2021-(11-29|11-30|12-01|12-02)' /var/log/postgresql/postgresql-10-main.log | grep -c 'still waiting for'
15
```
- I think you could analyze the locks for the `dspaceWeb` user (XMLUI) and find out what queries were locking... but it's so much information and I don't know where to start
- For now I just restarted PostgreSQL...
- Francesca was able to do her submission immediately...
- On a related note, I want to enable the `pg_stat_statement` feature to see which queries get run the most, so I created the extension on the CGSpace database
- I was doing some research on PostgreSQL locks and found some interesting things to consider
- The default `lock_timeout` is 0, aka disabled
- The default `statement_timeout` is 0, aka disabled
- It seems to be recommended to start by setting `statement_timeout` first, rule of thumb [ten times longer than your longest query](https://github.com/jberkus/annotated.conf/blob/master/postgresql.10.simple.conf#L211)
- Mark Wood mentioned the `checker` cron job that apparently runs in one transaction and might be an issue
- I definitely saw it holding a bunch of locks for ~30 minutes during the first part of its execution, then it dropped them and did some other less-intensive things without locks
- Bizuwork was still not receiving emails even after we fixed the SMTP access on CGSpace
- After some troubleshooting it turns out that the emails from CGSpace were going in her Junk!
## 2021-12-03
- I see GARDIAN is now using a "GARDIAN" user agent finally
- I will add them to our local spider agent override in DSpace so that the hits don't get counted in Solr
## 2021-12-05
- Proof fifty records Abenet sent me from Africa Rice Center ("AfricaRice 1st batch Import")
- Fixed forty-six incorrect collections
- Cleaned up and normalize affiliations
- Cleaned up dates (extra `*` character in all?)
- Cleaned up citation format
- Fixed some encoding issues in abstracts
- Removed empty columns
- Removed one duplicate: Enhancing Rice Productivity and Soil Nitrogen Using Dual-Purpose Cowpea-NERICA® Rice Sequence in Degraded Savanna
- Added volume and issue metadata by extracting it from the citations
- All PDFs hosted on davidpublishing.com are dead...
- All DOIs linking to African Journal of Agricultural Research are dead...
- Fixed a handful of items marked as "Open Access" that are actually closed
- Added many missing ISSNs
- Added many missing countries/regions
- Fixed invalid AGROVOC terms and added some more based on article subjects
- I also made some minor changes to the [CSV Metadata Quality Checker](https://github.com/ilri/csv-metadata-quality)
- Added the ability to check if the item's title exists in the citation
- Updated to only run the mojibake check if we're not running in unsafe mode (so we don't print the same warning during both the check and fix steps)
- I ran the re-harvesting on AReS
