## 2016-05-01

- Since yesterday there have been 10,000 REST errors and the site has been unstable again
- I have blocked access to the API now
- There are 3,000 IPs accessing the REST API in a 24-hour period!

```
# awk '{print $1}' /var/log/nginx/rest.log  | uniq | wc -l
3168
```

- The two most often requesters are in Ethiopia and Colombia: 213.55.99.121 and 181.118.144.29
- 100% of the requests coming from Ethiopia are like this and result in an HTTP 500:

```
GET /rest/handle/10568/NaN?expand=parentCommunityList,metadata HTTP/1.1
```

- For now I'll block just the Ethiopian IP
- The owner of that application has said that the `NaN` (not a number) is an error in his code and he'll fix it

- Update nginx to 1.10.x branch on CGSpace
- Fix a reference to `dc.type.output` in Discovery that I had missed when we migrated to `dc.type` last month ([#223](https://github.com/ilri/DSpace/pull/223))

- DSpace Test is down, `catalina.out` has lots of messages about heap space from some time yesterday (!)
- It looks like Sisay was doing some batch imports
- Hmm, also disk space is full
- I decided to blow away the solr indexes, since they are 50GB and we don't really need all the Atmire stuff there right now
- I will re-generate the Discovery indexes after re-deploying
- Testing `renew-letsencrypt.sh` script for nginx

```
#!/usr/bin/env bash

readonly SERVICE_BIN=/usr/sbin/service
readonly LETSENCRYPT_BIN=/opt/letsencrypt/letsencrypt-auto

# stop nginx so LE can listen on port 443
$SERVICE_BIN nginx stop

$LETSENCRYPT_BIN renew -nvv --standalone --standalone-supported-challenges tls-sni-01 > /var/log/letsencrypt/renew.log 2>&1

LE_RESULT=$?

$SERVICE_BIN nginx start

if [[ "$LE_RESULT" != 0 ]]; then
    echo 'Automated renewal failed:'

    cat /var/log/letsencrypt/renew.log

    exit 1
fi
```

- Seems to work well

## 2016-05-10

- Start looking at more metadata migrations
- There are lots of fields in `dcterms` namespace that look interesting, like:
  - dcterms.type
  - dcterms.spatial
- Not sure what `dcterms` is...
- Looks like these were [added in DSpace 4](https://wiki.duraspace.org/display/DSDOC5x/Metadata+and+Bitstream+Format+Registries#MetadataandBitstreamFormatRegistries-DublinCoreTermsRegistry(DCTERMS)) to allow for future work to make DSpace more flexible
- CGSpace's `dc` registry has 96 items, and the default DSpace one has 73.

## 2016-05-11

- Identify and propose the next phase of CGSpace fields to migrate:
  - dc.title.jtitle      → cg.title.journal
  - dc.identifier.status → cg.identifier.status
  - dc.river.basin       → cg.river.basin
  - dc.Species           → cg.species
  - dc.targetaudience    → cg.targetaudience
  - dc.fulltextstatus    → cg.fulltextstatus
  - dc.editon            → cg.edition
  - dc.isijournal        → cg.isijournal

- Start a test rebase of the `5_x-prod` branch on top of the `dspace-5.5` tag
- There were a handful of conflicts that I didn't understand
- After completing the rebase I tried to build with the module versions Atmire had indicated as being 5.5 ready but I got this error:

```
[ERROR] Failed to execute goal on project additions: Could not resolve dependencies for project org.dspace.modules:additions:jar:5.5: Could not find artifact com.atmire:atmire-metadata-quality-api:jar:5.5-2.10.1-0 in sonatype-releases (https://oss.sonatype.org/content/repositories/releases/) -> [Help 1]
```

- I've sent them a question about it
- A user mentioned having problems with uploading a 33 MB PDF
- I told her I would increase the limit temporarily tomorrow morning
