- Update [dspace-statistics-api](https://github.com/ilri/dspace-statistics-api) for DSpace 6+ UUIDs
- Tag version 1.2.0 on GitHub
- Test migrating legacy Solr statistics to UUIDs with the as-of-yet unreleased [SolrUpgradePre6xStatistics.java](https://github.com/DSpace/DSpace/commit/184f2b2153479045fba6239342c63e7f8564b8b6#diff-0350ce2e13b28d5d61252b7a8f50a059)
- You need to download this into the DSpace 6.x source and compile it
- I found a very [interesting comment on the Solr 8.1 guide](https://lucene.apache.org/solr/guide/8_1/solr-system-requirements.html#lucene-solr-prior-to-7-0) about Java compatibility:
> Lucene/Solr 7.0 was the first version that successfully passed our tests using Java 9 and higher. You should avoid Java 9 or later for Lucene/Solr 6.x or earlier.

- I want to try to consolidate our yearly Solr statistics cores back into one `statistics` core using the solr-import-export-json tool
- I will try it on DSpace test, doing one year at a time:
```
$ ./run.sh -s http://localhost:8081/solr/statistics-2010 -a export -o /tmp/statistics-2010.json -k uid
$ ./run.sh -s http://localhost:8081/solr/statistics -a import -o /tmp/statistics-2010.json -k uid
- Peter noticed that the Solr stats were not showing anything before 2020
- I had to restart Tomcat three times before all cores loaded properly...

- Fix some logic issues in the nginx config
- Use generic blocking of `[Bb]ot` and `[Cc]rawl` and `[Ss]pider` in the "badbots" rate limiting logic instead of trying to list them all one by one (bots should not be trying to index dynamic pages *no matter what* so we punish hard here)
- We were not properly forwarding the remote IP address to Tomcat in all nginx location blocks, which led some locations to log a hit from 127.0.0.1 (because we need to explicitly add the global proxy params when setting other headers in location blocks)
- Unfortunately this affected the REST API and there are a few hundred thousand requests from this user agent:
```
Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13 (.NET CLR 3.5.30729)
- It is making 10,000 to 40,000 requests to XMLUI per day...
```

```
- I will purge those hits too!
```
$ curl -s "http://localhost:8081/solr/statistics/update?softCommit=true" -H "Content-Type: text/xml" --data-binary '<delete><query>userAgent:"Mozilla/5.0 ((Windows; U; Windows NT 6.1; fr; rv:1.9.2) Gecko/20100115 Firefox/3.6)"</query></delete>'
```
- Shit, and something happened and a few thousand hits from user agents with "Bot" in their user agent got through
- I need to re-run the `check-bot-hits.sh` script with the standard COUNTER-Robots list again, but add my own versions of a few because the script/Solr doesn't support case-insensitive regular expressions:
```
