--- title: "April, 2019" date: 2019-04-01T09:00:43+03:00 author: "Alan Orth" categories: ["Notes"] --- ## 2019-04-01 - Meeting with AgroKnow to discuss CGSpace, ILRI data, AReS, GARDIAN, etc - They asked if we had plans to enable RDF support in CGSpace - There have been 4,400 more downloads of the CTA Spore publication from those strange Amazon IP addresses today - I suspected that some might not be successful, because the stats show less, but today they were all HTTP 200! ``` # cat /var/log/nginx/access.log /var/log/nginx/access.log.1 | grep 'Spore-192-EN-web.pdf' | grep -E '(18.196.196.108|18.195.78.144|18.195.218.6)' | awk '{print $9}' | sort | uniq -c | sort -n | tail -n 5 4432 200 ``` - In the last two weeks there have been 47,000 downloads of this *same exact PDF* by these three IP addresses - Apply country and region corrections and deletions on DSpace Test and CGSpace: ``` $ ./fix-metadata-values.py -i /tmp/2019-02-21-fix-9-countries.csv -db dspace -u dspace -p 'fuuu' -f cg.coverage.country -m 228 -t ACTION -d $ ./fix-metadata-values.py -i /tmp/2019-02-21-fix-4-regions.csv -db dspace -u dspace -p 'fuuu' -f cg.coverage.region -m 231 -t action -d $ ./delete-metadata-values.py -i /tmp/2019-02-21-delete-2-countries.csv -db dspace -u dspace -p 'fuuu' -m 228 -f cg.coverage.country -d $ ./delete-metadata-values.py -i /tmp/2019-02-21-delete-1-region.csv -db dspace -u dspace -p 'fuuu' -m 231 -f cg.coverage.region -d ``` ## 2019-04-02 - CTA says the Amazon IPs are AWS gateways for real user traffic - I was trying to add Felix Shaw's account back to the Administrators group on DSpace Test, but I couldn't find his name in the user search of the groups page - If I searched for "Felix" or "Shaw" I saw other matches, included one for his personal email address! - I ended up finding him via searching for his email address ## 2019-04-03 - Maria from Bioversity emailed me a list of new ORCID identifiers for their researchers so I will add them to our controlled vocabulary - First I need to extract the ones that are unique from their list compared to our existing one: ``` $ cat dspace/config/controlled-vocabularies/cg-creator-id.xml /tmp/bioversity.txt | grep -oE '[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{4}' | sort -u > /tmp/2019-04-03-orcid-ids.txt ``` - We currently have 1177 unique ORCID identifiers, and this brings our total to 1237! - Next I will resolve all their names using my `resolve-orcids.py` script: ``` $ ./resolve-orcids.py -i /tmp/2019-04-03-orcid-ids.txt -o 2019-04-03-orcid-ids.txt -d ``` - After that I added the XML formatting, formatted the file with tidy, and sorted the names in vim - One user's name has changed so I will update those using my `fix-metadata-values.py` script: ``` $ ./fix-metadata-values.py -i 2019-04-03-update-orcids.csv -db dspace -u dspace -p 'fuuu' -f cg.creator.id -m 240 -t correct -d ``` - I created a pull request and merged the changes to the `5_x-prod` branch ([#417](https://github.com/ilri/DSpace/pull/417)) - A few days ago I noticed some weird update process for the statistics-2018 Solr core and I see it's still going: ``` 2019-04-03 16:34:02,262 INFO org.dspace.statistics.SolrLogger @ Updating : 1754500/21701 docs in http://localhost:8081/solr//statistics-2018 ``` - Interestingly, there are 5666 occurences, and they are mostly for the 2018 core: ``` $ grep 'org.dspace.statistics.SolrLogger @ Updating' /home/cgspace.cgiar.org/log/dspace.log.2019-04-03 | awk '{print $11}' | sort | uniq -c 1 3 http://localhost:8081/solr//statistics-2017 5662 http://localhost:8081/solr//statistics-2018 ``` - I will have to keep an eye on it because nothing should be updating 2018 stats in 2019... ## 2019-04-05 - Uptime Robot reported that CGSpace (linode18) went down tonight - I see there are lots of PostgreSQL connections: ``` $ psql -c 'select * from pg_stat_activity' | grep -o -E '(dspaceWeb|dspaceApi|dspaceCli)' | sort | uniq -c 5 dspaceApi 10 dspaceCli 250 dspaceWeb ``` - I still see those weird messages about updating the statistics-2018 Solr core: ``` 2019-04-05 21:06:53,770 INFO org.dspace.statistics.SolrLogger @ Updating : 2444600/21697 docs in http://localhost:8081/solr//statistics-2018 ``` - Looking at `iostat 1 10` I also see some CPU steal has come back, and I can confirm it by looking at the Munin graphs: ![CPU usage week](/cgspace-notes/2019/04/cpu-week.png) - The other thing visible there is that the past few days the load has spiked to 500% and I don't think it's a coincidence that the Solr updating thing is happening... - I ran all system updates and rebooted the server - The load was lower on the server after reboot, but Solr didn't come back up properly according to the Solr Admin UI: ``` statistics-2017: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error opening new searcher ``` - I restarted it again and all the Solr cores came up properly... ## 2019-04-06 - Udana asked why item [10568/91278](https://cgspace.cgiar.org/handle/10568/91278) didn't have an Altmetric badge on CGSpace, but on the [WLE website](https://wle.cgiar.org/food-and-agricultural-innovation-pathways-prosperity) it does - I looked and saw that the WLE website is using the Altmetric score associated with the DOI, and that the Handle has no score at all - I tweeted the item and I assume this will link the Handle with the DOI in the system - Twenty minutes later I see the same Altmetric score (9) on CGSpace - Linode sent an alert that there was high CPU usage this morning on CGSpace (linode18) and these were the top IPs in the webserver access logs around the time: ``` # zcat --force /var/log/nginx/{access,error,library-access}.log /var/log/nginx/{access,error,library-access}.log.1 | grep -E "06/Apr/2019:(06|07|08|09)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10 222 18.195.78.144 245 207.46.13.58 303 207.46.13.194 328 66.249.79.33 564 207.46.13.210 566 66.249.79.62 575 40.77.167.66 1803 66.249.79.59 2834 2a01:4f8:140:3192::2 9623 45.5.184.72 # zcat --force /var/log/nginx/{rest,oai}.log /var/log/nginx/{rest,oai}.log.1 | grep -E "06/Apr/2019:(06|07|08|09)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10 31 66.249.79.62 41 207.46.13.210 42 40.77.167.66 54 42.113.50.219 132 66.249.79.59 785 2001:41d0:d:1990:: 1164 45.5.184.72 2014 50.116.102.77 4267 45.5.186.2 4893 205.186.128.185 ``` - `45.5.184.72` is in Colombia so it's probably CIAT, and I see they are indeed trying to get crawl the Discover pages on CIAT's datasets collection: ``` GET /handle/10568/72970/discover?filtertype_0=type&filtertype_1=author&filter_relational_operator_1=contains&filter_relational_operator_0=equals&filter_1=&filter_0=Dataset&filtertype=dateIssued&filter_relational_operator=equals&filter=2014 ``` - Their user agent is the one I added to the badbots list in nginx last week: "GuzzleHttp/6.3.3 curl/7.47.0 PHP/7.0.30-0ubuntu0.16.04.1" - They made 22,000 requests to Discover on this collection today alone (and it's only 11AM): ``` # cat /var/log/nginx/access.log /var/log/nginx/access.log.1 | grep "06/Apr/2019" | grep 45.5.184.72 | grep -oE '/handle/[0-9]+/[0-9]+/discover' | sort | uniq -c 22077 /handle/10568/72970/discover ``` - Yesterday they made 43,000 requests and we actually blocked most of them: ``` # zcat --force /var/log/nginx/access.log /var/log/nginx/access.log.1 /var/log/nginx/access.log.2.gz | grep "05/Apr/2019" | grep 45.5.184.72 | grep -oE '/handle/[0-9]+/[0-9]+/discover' | sort | uniq -c 43631 /handle/10568/72970/discover # zcat --force /var/log/nginx/access.log /var/log/nginx/access.log.1 /var/log/nginx/access.log.2.gz | grep "05/Apr/2019" | grep 45.5.184.72 | grep -E '/handle/[0-9]+/[0-9]+/discover' | awk '{print $9}' | sort | uniq -c 142 200 43489 503 ``` - I need to find a contact at CIAT to tell them to use the REST API rather than crawling Discover - Maria from Bioversity recommended that we use the phrase "AGROVOC subject" instead of "Subject" in Listings and Reports - I made a pull request to update this and merged it to the `5_x-prod` branch ([#418](https://github.com/ilri/DSpace/pull/418)) ## 2019-04-07 - Looking into the impact of harvesters like `45.5.184.72`, I see in Solr that this user is not categorized as a bot so it definitely impacts the usage stats by some tens of thousands *per day* - Last week CTA switched their frontend code to use HEAD requests instead of GET requests for bitstreams - I am trying to see if these are registered as downloads in Solr or not - I see 96,925 downloads from their AWS gateway IPs in 2019-03: ``` $ http --print b 'http://localhost:8081/solr/statistics/select?q=type%3A0+AND+(ip%3A18.196.196.108+OR+ip%3A18.195.78.144+OR+ip%3A18.195.218.6)&fq=statistics_type%3Aview&fq=bundleName%3AORIGINAL&fq=dateYearMonth%3A2019-03&rows=0&wt=json&indent=true' { "response": { "docs": [], "numFound": 96925, "start": 0 }, "responseHeader": { "QTime": 1, "params": { "fq": [ "statistics_type:view", "bundleName:ORIGINAL", "dateYearMonth:2019-03" ], "indent": "true", "q": "type:0 AND (ip:18.196.196.108 OR ip:18.195.78.144 OR ip:18.195.218.6)", "rows": "0", "wt": "json" }, "status": 0 } } ``` - Strangely I don't see many hits in 2019-04: ``` $ http --print b 'http://localhost:8081/solr/statistics/select?q=type%3A0+AND+(ip%3A18.196.196.108+OR+ip%3A18.195.78.144+OR+ip%3A18.195.218.6)&fq=statistics_type%3Aview&fq=bundleName%3AORIGINAL&fq=dateYearMonth%3A2019-04&rows=0&wt=json&indent=true' { "response": { "docs": [], "numFound": 38, "start": 0 }, "responseHeader": { "QTime": 1, "params": { "fq": [ "statistics_type:view", "bundleName:ORIGINAL", "dateYearMonth:2019-04" ], "indent": "true", "q": "type:0 AND (ip:18.196.196.108 OR ip:18.195.78.144 OR ip:18.195.218.6)", "rows": "0", "wt": "json" }, "status": 0 } } ``` - Making some tests on GET vs HEAD requests on the [CTA Spore 192 item](https://dspacetest.cgiar.org/handle/10568/100289) on DSpace Test: ``` $ http --print Hh GET https://dspacetest.cgiar.org/bitstream/handle/10568/100289/Spore-192-EN-web.pdf GET /bitstream/handle/10568/100289/Spore-192-EN-web.pdf HTTP/1.1 Accept: */* Accept-Encoding: gzip, deflate Connection: keep-alive Host: dspacetest.cgiar.org User-Agent: HTTPie/1.0.2 HTTP/1.1 200 OK Connection: keep-alive Content-Language: en-US Content-Length: 2069158 Content-Type: application/pdf;charset=ISO-8859-1 Date: Sun, 07 Apr 2019 08:38:34 GMT Expires: Sun, 07 Apr 2019 09:38:34 GMT Last-Modified: Thu, 14 Mar 2019 11:20:05 GMT Server: nginx Set-Cookie: JSESSIONID=21A492CC31CA8845278DFA078BD2D9ED; Path=/; Secure; HttpOnly Vary: User-Agent X-Cocoon-Version: 2.2.0 X-Content-Type-Options: nosniff X-Frame-Options: SAMEORIGIN X-Robots-Tag: none X-XSS-Protection: 1; mode=block $ http --print Hh HEAD https://dspacetest.cgiar.org/bitstream/handle/10568/100289/Spore-192-EN-web.pdf HEAD /bitstream/handle/10568/100289/Spore-192-EN-web.pdf HTTP/1.1 Accept: */* Accept-Encoding: gzip, deflate Connection: keep-alive Host: dspacetest.cgiar.org User-Agent: HTTPie/1.0.2 HTTP/1.1 200 OK Connection: keep-alive Content-Language: en-US Content-Length: 2069158 Content-Type: application/pdf;charset=ISO-8859-1 Date: Sun, 07 Apr 2019 08:39:01 GMT Expires: Sun, 07 Apr 2019 09:39:01 GMT Last-Modified: Thu, 14 Mar 2019 11:20:05 GMT Server: nginx Set-Cookie: JSESSIONID=36C8502257CC6C72FD3BC9EBF91C4A0E; Path=/; Secure; HttpOnly Vary: User-Agent X-Cocoon-Version: 2.2.0 X-Content-Type-Options: nosniff X-Frame-Options: SAMEORIGIN X-Robots-Tag: none X-XSS-Protection: 1; mode=block ``` - And from the server side, the nginx logs show: ``` 78.x.x.x - - [07/Apr/2019:01:38:35 -0700] "GET /bitstream/handle/10568/100289/Spore-192-EN-web.pdf HTTP/1.1" 200 68078 "-" "HTTPie/1.0.2" 78.x.x.x - - [07/Apr/2019:01:39:01 -0700] "HEAD /bitstream/handle/10568/100289/Spore-192-EN-web.pdf HTTP/1.1" 200 0 "-" "HTTPie/1.0.2" ``` - So definitely the *size* of the transfer is more efficient with a HEAD, but I need to wait to see if these requests show up in Solr - After twenty minutes of waiting I still don't see any new requests in the statistics core, but when I try the requests from the command line again I see the following in the DSpace log: ``` 2019-04-07 02:05:30,966 INFO org.dspace.usage.LoggerUsageEventListener @ anonymous:session_id=EF2DB6E4F69926C5555B3492BB0071A8:ip_addr=78.x.x.x:view_bitstream:bitstream_id=165818 2019-04-07 02:05:39,265 INFO org.dspace.usage.LoggerUsageEventListener @ anonymous:session_id=B6381FC590A5160D84930102D068C7A3:ip_addr=78.x.x.x:view_bitstream:bitstream_id=165818 ``` - So my inclination is that both HEAD and GET requests are registered as views as far as Solr and DSpace are concerned - Strangely, the statistics Solr core says it hasn't been modified in 24 hours, so I tried to start the "optimize" process from the Admin UI and I see this in the Solr log: ``` 2019-04-07 02:08:44,186 INFO org.apache.solr.update.UpdateHandler @ start commit{,optimize=true,openSearcher=true,waitSearcher=true,expungeDeletes=false,softCommit=false,prepareCommit=false} ``` - Ugh, even after optimizing there are no Solr results for requests from my IP, and actually I only see 18 results from 2019-04 so far and none of them are `statistics_type:view`... very weird - I don't even see many hits for days after 2019-03-17, when I migrated the server to Ubuntu 18.04 and copied the statistics core from CGSpace (linode18) - I will try to re-deploy the `5_x-dev` branch and test again - According to the [DSpace 5.x Solr documentation](https://wiki.lyrasis.org/display/DSDOC5x/SOLR+Statistics) the default commit time is after 15 minutes or 10,000 documents (see `solrconfig.xml`) - I looped some GET and HEAD requests to a bitstream on my local instance and after some time I see that they *do* register as downloads (even though they are internal): ``` $ http --print b 'http://localhost:8080/solr/statistics/select?q=type%3A0+AND+time%3A2019-04-07*&fq=statistics_type%3Aview&fq=isInternal%3Atrue&rows=0&wt=json&indent=true' { "response": { "docs": [], "numFound": 909, "start": 0 }, "responseHeader": { "QTime": 0, "params": { "fq": [ "statistics_type:view", "isInternal:true" ], "indent": "true", "q": "type:0 AND time:2019-04-07*", "rows": "0", "wt": "json" }, "status": 0 } } ``` - I confirmed the same on CGSpace itself after making one HEAD request - So I'm pretty sure it's something about DSpace Test using the CGSpace statistics core, and not that I deployed Solr 4.10.4 there last week - I deployed Solr 4.10.4 locally and ran a bunch of requests for bitstreams and they do show up in the Solr statistics log, so the issue must be with re-using the existing Solr core from CGSpace - Now this gets more frustrating: I did the same GET and HEAD tests on a local Ubuntu 16.04 VM with Solr 4.10.2 and 4.10.4 and the statistics are recorded - This leads me to believe there is something specifically wrong with DSpace Test (linode19) - The only thing I can think of is that the JVM is using G1GC instead of ConcMarkSweepGC - Holy shit, all this is actually because of the GeoIP1 deprecation and a missing `GeoLiteCity.dat` - For some reason the missing GeoIP data causes stats to not be recorded whatsoever and there is no error! - See: [DS-3986](https://jira.duraspace.org/browse/DS-3986) - See: [DS-4020](https://jira.duraspace.org/browse/DS-4020) - See: [DS-3832](https://jira.duraspace.org/browse/DS-3832) - DSpace 5.10 upgraded to use GeoIP2, but we are on 5.8 so I just copied the missing database file from another server because it has been *removed* from MaxMind's server as of 2018-04-01 - Now I made 100 requests and I see them in the Solr statistics... fuck my life for wasting five hours debugging this - UptimeRobot said CGSpace went down and up a few times tonight, and my first instict was to check `iostat 1 10` and I saw that CPU steal is around 10–30 percent right now... - The load average is super high right now, as I've noticed the last few times UptimeRobot said that CGSpace went down: ``` $ cat /proc/loadavg 10.70 9.17 8.85 18/633 4198 ``` - According to the server logs there is actually not much going on right now: ``` # zcat --force /var/log/nginx/{access,library-access}.log /var/log/nginx/{access,library-access}.log.1 | grep -E "07/Apr/2019:(18|19|20)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10 118 18.195.78.144 128 207.46.13.219 129 167.114.64.100 159 207.46.13.129 179 207.46.13.33 188 2408:8214:7a00:868f:7c1e:e0f3:20c6:c142 195 66.249.79.59 363 40.77.167.21 740 2a01:4f8:140:3192::2 4823 45.5.184.72 # zcat --force /var/log/nginx/{rest,oai}.log /var/log/nginx/{rest,oai}.log.1 | grep -E "07/Apr/2019:(18|19|20)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10 3 66.249.79.62 3 66.249.83.196 4 207.46.13.86 5 82.145.222.150 6 2a01:4f9:2b:1263::2 6 41.204.190.40 7 35.174.176.49 10 40.77.167.21 11 194.246.119.6 11 66.249.79.59 ``` - `45.5.184.72` is CIAT, who I already blocked and am waiting to hear from - `2a01:4f8:140:3192::2` is BLEXbot, which should be handled by the Tomcat Crawler Session Manager Valve - `2408:8214:7a00:868f:7c1e:e0f3:20c6:c142` is some stupid Chinese bot making malicious POST requests - There are free database connections in the pool: ``` $ psql -c 'select * from pg_stat_activity' | grep -o -E '(dspaceWeb|dspaceApi|dspaceCli)' | sort | uniq -c 5 dspaceApi 7 dspaceCli 23 dspaceWeb ``` - It seems that the issue with CGSpace being "down" is actually because of CPU steal again!!! - I opened a ticket with support and asked them to migrate the VM to a less busy host ## 2019-04-08 - Start checking IITA's last round of batch uploads from [March on DSpace Test](https://dspacetest.cgiar.org/handle/10568/100333) (20193rd.xls) - Lots of problems with affiliations, I had to correct about sixty of them - I used lein to host the latest CSV of our affiliations for OpenRefine to reconcile against: ``` $ lein run ~/src/git/DSpace/2019-02-22-affiliations.csv name id ``` - After matching the values and creating some new matches I had trouble remembering how to copy the reconciled values to a new column - The matched values can be accessed with `cell.recon.match.name`, but some of the new values don't appear, perhaps because I edited the original cell values? - I ended up using this GREL expression to copy all values to a new column: ``` if(cell.recon.matched, cell.recon.match.name, value) ``` - See the [OpenRefine variables documentation](https://github.com/OpenRefine/OpenRefine/wiki/Variables#recon) for more notes about the `recon` object - I also noticed a handful of errors in our current list of affiliations so I corrected them: ``` $ ./fix-metadata-values.py -i 2019-04-08-fix-13-affiliations.csv -db dspace -u dspace -p 'fuuu' -f cg.contributor.affiliation -m 211 -t correct -d ``` - We should create a new list of affiliations to update our controlled vocabulary again - I dumped a list of the top 1500 affiliations: ``` dspace=# \COPY (SELECT DISTINCT text_value, count(*) FROM metadatavalue WHERE metadata_field_id = 211 AND resource_type_id = 2 GROUP BY text_value ORDER BY count DESC LIMIT 1500) to /tmp/2019-04-08-top-1500-affiliations.csv WITH CSV HEADER; COPY 1500 ``` - Fix a few more messed up affiliations that have return characters in them (use Ctrl-V Ctrl-M to re-create control character): ``` dspace=# UPDATE metadatavalue SET text_value='International Institute for Environment and Development' WHERE resource_type_id = 2 AND metadata_field_id = 211 AND text_value LIKE 'International Institute^M%'; dspace=# UPDATE metadatavalue SET text_value='Kenya Agriculture and Livestock Research Organization' WHERE resource_type_id = 2 AND metadata_field_id = 211 AND text_value LIKE 'Kenya Agricultural and Livestock Research^M%'; ``` - I noticed a bunch of subjects and affiliations that use stylized apostrophes so I will export those and then batch update them: ``` dspace=# \COPY (SELECT DISTINCT text_value FROM metadatavalue WHERE resource_type_id = 2 AND metadata_field_id = 211 AND text_value LIKE '%’%') to /tmp/2019-04-08-affiliations-apostrophes.csv WITH CSV HEADER; COPY 60 dspace=# \COPY (SELECT DISTINCT text_value FROM metadatavalue WHERE resource_type_id = 2 AND metadata_field_id = 57 AND text_value LIKE '%’%') to /tmp/2019-04-08-subject-apostrophes.csv WITH CSV HEADER; COPY 20 ``` - I cleaned them up in OpenRefine and then applied the fixes on CGSpace and DSpace Test: ``` $ ./fix-metadata-values.py -i /tmp/2019-04-08-fix-60-affiliations-apostrophes.csv -db dspace -u dspace -p 'fuuu' -f cg.contributor.affiliation -m 211 -t correct -d $ ./fix-metadata-values.py -i /tmp/2019-04-08-fix-20-subject-apostrophes.csv -db dspace -u dspace -p 'fuuu' -f dc.subject -m 57 -t correct -d ``` - UptimeRobot said that CGSpace (linode18) went down tonight - The load average is at `9.42, 8.87, 7.87` - I looked at PostgreSQL and see shitloads of connections there: ``` $ psql -c 'select * from pg_stat_activity' | grep -o -E '(dspaceWeb|dspaceApi|dspaceCli)' | sort | uniq -c 5 dspaceApi 7 dspaceCli 250 dspaceWeb ``` - On a related note I see connection pool errors in the DSpace log: ``` 2019-04-08 19:01:10,472 ERROR org.dspace.storage.rdbms.DatabaseManager @ SQL connection Error - org.apache.tomcat.jdbc.pool.PoolExhaustedException: [http-bio-127.0.0.1-8443-exec-319] Timeout: Pool empty. Unable to fetch a connection in 5 seconds, none available[size:250; busy:250; idle:0; lastwait:5000]. ``` - But still I see 10 to 30% CPU steal in `iostat` that is also reflected in the Munin graphs: ![CPU usage week](/cgspace-notes/2019/04/cpu-week2.png) - Linode Support still didn't respond to my ticket from yesterday, so I attached a new output of `iostat 1 10` and asked them to move the VM to a less busy host - The web server logs are not very busy: ``` # zcat --force /var/log/nginx/{access,library-access}.log /var/log/nginx/{access,library-access}.log.1 | grep -E "08/Apr/2019:(17|18|19)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10 124 40.77.167.135 135 95.108.181.88 139 157.55.39.206 190 66.249.79.133 202 45.5.186.2 284 207.46.13.95 359 18.196.196.108 457 157.55.39.164 457 40.77.167.132 3822 45.5.184.72 # zcat --force /var/log/nginx/{rest,oai}.log /var/log/nginx/{rest,oai}.log.1 | grep -E "08/Apr/2019:(17|18|19)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10 5 129.0.79.206 5 41.205.240.21 7 207.46.13.95 7 66.249.79.133 7 66.249.79.135 7 95.108.181.88 8 40.77.167.111 19 157.55.39.164 20 40.77.167.132 370 51.254.16.223 ``` ## 2019-04-09 - Linode sent an alert that CGSpace (linode18) was 440% CPU for the last two hours this morning - Here are the top IPs in the web server logs around that time: ``` # zcat --force /var/log/nginx/{rest,oai}.log /var/log/nginx/{rest,oai}.log.1 | grep -E "09/Apr/2019:(06|07|08)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10 18 66.249.79.139 21 157.55.39.160 29 66.249.79.137 38 66.249.79.135 50 34.200.212.137 54 66.249.79.133 100 102.128.190.18 1166 45.5.184.72 4251 45.5.186.2 4895 205.186.128.185 # zcat --force /var/log/nginx/{access,library-access}.log /var/log/nginx/{access,library-access}.log.1 | grep -E "09/Apr/2019:(06|07|08)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10 200 144.48.242.108 202 207.46.13.185 206 18.194.46.84 239 66.249.79.139 246 18.196.196.108 274 31.6.77.23 289 66.249.79.137 312 157.55.39.160 441 66.249.79.135 856 66.249.79.133 ``` - `45.5.186.2` is at CIAT in Colombia and I see they are mostly making requests to the REST API, but also to XMLUI with the following user agent: ``` Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Safari/537.36 ``` - Database connection usage looks fine: ``` $ psql -c 'select * from pg_stat_activity' | grep -o -E '(dspaceWeb|dspaceApi|dspaceCli)' | sort | uniq -c 5 dspaceApi 7 dspaceCli 11 dspaceWeb ``` - Ironically I do still see some 2 to 10% of CPU steal in `iostat 1 10` - Leroy from CIAT contacted me to say he knows the team who is making all those requests to CGSpace - I told them how to use the REST API to get the CIAT Datasets collection and enumerate its items - In other news, Linode staff identified a noisy neighbor sharing our host and migrated it elsewhere last night ## 2019-04-10 - Abenet pointed out a possibility of validating funders against the [CrossRef API](https://support.crossref.org/hc/en-us/articles/215788143-Funder-data-via-the-API) - Note that if you use HTTPS and specify a contact address in the API request you have less likelihood of being blocked ``` $ http 'https://api.crossref.org/funders?query=mercator&mailto=me@cgiar.org' ``` - Otherwise, they provide the funder data in [CSV and RDF format](https://www.crossref.org/services/funder-registry/) - I did a quick test with the recent IITA records against reconcile-csv in OpenRefine and it matched a few, but the ones that didn't match will need a human to go and do some manual checking and informed decision making... - If I want to write a script for this I could use the Python [habanero library](https://habanero.readthedocs.io/en/latest/modules/crossref.html): ``` from habanero import Crossref cr = Crossref(mailto="me@cgiar.org") x = cr.funders(query = "mercator") ``` ## 2019-04-11 - Continue proofing IITA's last round of batch uploads from [March on DSpace Test](https://dspacetest.cgiar.org/handle/10568/100333) (20193rd.xls) - One misspelled country - Three incorrect regions - Potential duplicates (same DOI, similar title, same authors): - [10568/100580](https://dspacetest.cgiar.org/handle/10568/100580) and [10568/100579](https://dspacetest.cgiar.org/handle/10568/100579) - [10568/100444](https://dspacetest.cgiar.org/handle/10568/100444) and [10568/100423](https://dspacetest.cgiar.org/handle/10568/100423) - Two DOIs with incorrect URL formatting - Two misspelled IITA subjects - Two authors with smart quotes - Lots of issues with sponsors - One misspelled "Peer review" - One invalid ISBN that I fixed by Googling the title - Lots of issues with sponsors (German Aid Agency, Swiss Aid Agency, Italian Aid Agency, Dutch Aid Agency, etc) - I validated all the AGROVOC subjects against our latest list with reconcile-csv - About 720 of the 900 terms were matched, then I checked and fixed or deleted the rest manually - I captured a few general corrections and deletions for AGROVOC subjects while looking at IITA's records, so I applied them to DSpace Test and CGSpace: ``` $ ./fix-metadata-values.py -i /tmp/2019-04-11-fix-14-subjects.csv -db dspace -u dspace -p 'fuuu' -f dc.subject -m 57 -t correct -d $ ./delete-metadata-values.py -i /tmp/2019-04-11-delete-6-subjects.csv -db dspace -u dspace -p 'fuuu' -m 57 -f dc.subject -d ``` - Answer more questions about DOIs and Altmetric scores from WLE - Answer more questions about DOIs and Altmetric scores from IWMI - They can't seem to understand the Altmetric + Twitter flow for associating Handles and DOIs - To make things worse, many of their items DON'T have DOIs, so when Altmetric harvests them of course there is no link! - Then, a bunch of their items don't have scores because they never tweeted them! - They added a DOI to this old item [10567/97087](https://cgspace.cgiar.org/handle/10568/97087) this morning and wonder why Altmetric's score hasn't linked with the DOI magically - We should check in a week to see if Altmetric will make the association after one week when they harvest again ## 2019-04-13 - I copied the `statistics` and `statistics-2018` Solr cores from CGSpace to my local machine and watched the Java process in VisualVM while indexing item views and downloads with my [dspace-statistics-api](https://github.com/ilri/dspace-statistics-api): ![Java GC during Solr indexing with CMS](/cgspace-notes/2019/04/visualvm-solr-indexing.png) - It took about eight minutes to index 784 pages of item views and 268 of downloads, and you can see a clear "sawtooth" pattern in the garbage collection - I am curious if the GC pattern would be different if I switched from the `-XX:+UseConcMarkSweepGC` to G1GC - I switched to G1GC and restarted Tomcat but for some reason I couldn't see the Tomcat PID in VisualVM... - Anyways, the indexing process took much longer, perhaps twice as long! - I tried again with the GC tuning settings from the Solr 4.10.4 release: ![Java GC during Solr indexing Solr 4.10.4 settings](/cgspace-notes/2019/04/visualvm-solr-indexing-solr-settings.png) ## 2019-04-14 - Change DSpace Test (linode19) to use the Java GC tuning from the Solr 4.10.4 startup script: ``` GC_TUNE="-XX:NewRatio=3 \ -XX:SurvivorRatio=4 \ -XX:TargetSurvivorRatio=90 \ -XX:MaxTenuringThreshold=8 \ -XX:+UseConcMarkSweepGC \ -XX:+UseParNewGC \ -XX:ConcGCThreads=4 -XX:ParallelGCThreads=4 \ -XX:+CMSScavengeBeforeRemark \ -XX:PretenureSizeThreshold=64m \ -XX:+UseCMSInitiatingOccupancyOnly \ -XX:CMSInitiatingOccupancyFraction=50 \ -XX:CMSMaxAbortablePrecleanTime=6000 \ -XX:+CMSParallelRemarkEnabled \ -XX:+ParallelRefProcEnabled" ``` - I need to remember to check the Munin JVM graphs in a few days - It might be placebo, but the site *does* feel snappier... ## 2019-04-15 - Rework the dspace-statistics-api to use the vanilla Python requests library instead of Solr client - [Tag version 1.0.0](https://github.com/ilri/dspace-statistics-api/releases/tag/v1.0.0) and deploy it on DSpace Test - Pretty annoying to see CGSpace (linode18) with 20–50% CPU steal according to `iostat 1 10`, though I haven't had any Linode alerts in a few days - Abenet sent me a list of ILRI items that don't have CRPs added to them - The spreadsheet only had Handles (no IDs), so I'm experimenting with using Python in OpenRefine to get the IDs - I cloned the handle column and then did a transform to get the IDs from the CGSpace REST API: ``` import json import re import urllib import urllib2 handle = re.findall('[0-9]+/[0-9]+', value) url = 'https://cgspace.cgiar.org/rest/handle/' + handle[0] req = urllib2.Request(url) req.add_header('User-agent', 'Alan Python bot') res = urllib2.urlopen(req) data = json.load(res) item_id = data['id'] return item_id ``` - Luckily none of the items already had CRPs, so I didn't have to worry about them getting removed - It would have been much trickier if I had to get the CRPs for the items first, then add the CRPs... - I ran a full Discovery indexing on CGSpace because I didn't do it after all the metadata updates last week: ``` $ time schedtool -B -e ionice -c2 -n7 nice -n19 dspace index-discovery -b real 82m45.324s user 7m33.446s sys 2m13.463s ``` ## 2019-04-16 - Export IITA's community from CGSpace because they want to experiment with importing it into their internal DSpace for some testing or something ## 2019-04-17 - Reading an interesting [blog post about Solr caching](https://teaspoon-consulting.com/articles/solr-cache-tuning.html) - Did some tests of the dspace-statistics-api on my local DSpace instance with 28 million documents in a sharded statistics core (`statistics` and `statistics-2018`) and monitored the memory usage of Tomcat in VisualVM - 4GB heap, CMS GC, 512 filter cache, 512 query cache, with 28 million documents in two shards - Run 1: - Time: 3.11s user 0.44s system 0% cpu 13:45.07 total - Tomcat (not Solr) max JVM heap usage: 2.04 GiB -

The biggest takeaway I have is that this workload benefits from a larger `filterCache` (for Solr fq parameter), but barely uses the `queryResultCache` (for Solr q parameter) at all - The number of hits goes up and the time taken decreases when we increase the `filterCache`, and total JVM heap memory doesn't seem to increase much at all - I guess the `queryResultCache` size is always 2 because I'm only doing two queries: `type:0` and `type:2` (downloads and views, respectively) - Here is the general pattern of running three sequential indexing runs as seen in VisualVM while monitoring the Tomcat process: ![VisualVM Tomcat 4096 filterCache](/cgspace-notes/2019/04/visualvm-solr-indexing-4096-filterCache.png) - I ran one test with a `filterCache` of 16384 to try to see if I could make the Tomcat JVM memory balloon, but actually it *drastically* increased the performance and memory usage of the dspace-statistics-api indexer - 4GB heap, CMS GC, 16384 filter cache, 512 query cache, with 28 million documents in two shards - Run 1: - Time: 2.85s user 0.42s system 2% cpu 2:28.92 total - Tomcat max JVM heap usage: 1.90 GiB - `filterCache` size: 14851, `cumulative_lookups`: 2354237, `cumulative_hits`: 2331186, `cumulative_hitratio`: 0.99 - Run 2: - Time: 2.90s user 0.37s system 2% cpu 2:23.50 total - Tomcat max JVM heap usage: 1.27 GiB - `filterCache` size: 15834, `cumulative_lookups`: 4708476, `cumulative_hits`: 4664762, `cumulative_hitratio`: 0.99 - Run 3: - Time: 2.93s user 0.39s system 2% cpu 2:26.17 total - Tomcat max JVM heap usage: 1.05 GiB - `filterCache` size: 15248, `cumulative_lookups`: 7062715, `cumulative_hits`: 6998267, `cumulative_hitratio`: 0.99 - The JVM garbage collection graph is MUCH flatter, and memory usage is much lower (not to mention a drop in GC-related CPU usage)! ![VisualVM Tomcat 16384 filterCache](/cgspace-notes/2019/04/visualvm-solr-indexing-16384-filterCache.png) - I will deploy this `filterCache` setting on DSpace Test (linode19) - Run all system updates on DSpace Test (linode19) and reboot it - Lots of CPU steal going on still on CGSpace (linode18): ![CPU usage week](/cgspace-notes/2019/04/cpu-week3.png) ## 2019-04-18 - I've been trying to copy the `statistics-2018` Solr core from CGSpace to DSpace Test since yesterday, but the network speed is like 20KiB/sec - I opened a support ticket to ask Linode to investigate - They asked me to send an `mtr` report from Fremont to Frankfurt and vice versa - Deploy Tomcat 7.0.94 on DSpace Test (linode19) - Also, I realized that the CMS GC changes I deployed a few days ago were ignored by Tomcat because of something with how Ansible formatted the options string - I needed to use the "folded" YAML variable format `>-` (with the dash so it doesn't add a return at the end) - UptimeRobot says that CGSpace went "down" this afternoon, but I looked at the CPU steal with `iostat 1 10` and it's in the 50s and 60s - The munin graph shows a lot of CPU steal (red) currently (and over all during the week): ![CPU usage week](/cgspace-notes/2019/04/cpu-week4.png) - I opened a ticket with Linode to migrate us somewhere - They agreed to migrate us to a quieter host ## 2019-04-20 - Linode agreed to move CGSpace (linode18) to a new machine shortly after I filed my ticket about CPU steal two days ago and now the load is much more sane: ![CPU usage week](/cgspace-notes/2019/04/cpu-week5.png) - For future reference, Linode mentioned that they consider CPU steal above 8% to be significant - Regarding the other Linode issue about speed, I did a test with `iperf` between linode18 and linode19: ``` # iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ [ 4] local 45.79.x.x port 5001 connected with 139.162.x.x port 51378 ------------------------------------------------------------ Client connecting to 139.162.x.x, TCP port 5001 TCP window size: 85.0 KByte (default) ------------------------------------------------------------ [ 5] local 45.79.x.x port 36440 connected with 139.162.x.x port 5001 [ ID] Interval Transfer Bandwidth [ 5] 0.0-10.2 sec 172 MBytes 142 Mbits/sec [ 4] 0.0-10.5 sec 202 MBytes 162 Mbits/sec ``` - Even with the software firewalls disabled the rsync speed was low, so it's not a rate limiting issue - I also tried to download a file over HTTPS from CGSpace to DSpace Test, but it was capped at 20KiB/sec - I updated the Linode issue with this information - I'm going to try to switch the kernel to the latest upstream (5.0.8) instead of Linode's latest x86_64 - Nope, still 20KiB/sec ## 2019-04-21 - Deploy Solr 4.10.4 on CGSpace (linode18) - Deploy Tomcat 7.0.94 on CGSpace - Deploy dspace-statistics-api v1.0.0 on CGSpace - Linode support replicated the results I had from the network speed testing and said they don't know why it's so slow - They offered to live migrate the instance to another host to see if that helps ## 2019-04-22 - Abenet pointed out [an item](https://hdl.handle.net/10568/97912) that doesn't have an Altmetric score on CGSpace, but has a score of 343 in the CGSpace Altmetric dashboard - I tweeted the Handle to see if it will pick it up... - Like clockwork, after fifteen minutes there was a donut showing on CGSpace - I want to get rid of this annoying warning that is constantly in our DSpace logs: ``` 2019-04-08 19:02:31,770 WARN org.dspace.xoai.services.impl.xoai.DSpaceRepositoryConfiguration @ { OAI 2.0 :: DSpace } Not able to retrieve the dspace.oai.url property from oai.cfg. Falling back to request address ``` - Apparently it happens once per request, which can be at least 1,500 times per day according to the DSpace logs on CGSpace (linode18): ``` $ grep -c 'Falling back to request address' dspace.log.2019-04-20 dspace.log.2019-04-20:1515 ``` - I will fix it in `dspace/config/modules/oai.cfg` - Linode says that it is likely that the host CGSpace (linode18) is on is showing signs of hardware failure and they recommended that I migrate the VM to a new host - I told them to migrate it at 04:00:00AM Frankfurt time, when nobody in East Africa, Europe, or South America should be using the server ## 2019-04-23 - One blog post says that there is [no overprovisioning in Azure](https://kvaes.wordpress.com/2017/07/01/what-azure-virtual-machine-size-should-i-pick/):
In Azure, with one exception being the A0, there is no overprovisioning… Each physical cores is only supporting one virtual core.
- Perhaps that's why the [Azure pricing](https://azure.microsoft.com/en-us/pricing/details/virtual-machines/linux/) is so expensive! - Add a privacy page to CGSpace - The work was mostly similar to the About page at `/page/about`, but in addition to adding i18n strings etc, I had to add the logic for the trail to `dspace-xmlui-mirage2/src/main/webapp/xsl/preprocess/general.xsl` ## 2019-04-24 - Linode migrated CGSpace (linode18) to a new host, but I am still getting poor performance when copying data to DSpace Test (linode19) - I asked them if we can migrate DSpace Test to a new host - They migrated DSpace Test to a new host and the rsync speed from Frankfurt was still capped at 20KiB/sec... - I booted DSpace Test to a rescue CD and tried the rsync from CGSpace there too, but it was still capped at 20KiB/sec... - I copied the 18GB `statistics-2018` Solr core from Frankfurt to a Linode in London at 15MiB/sec, then from the London one to DSpace Test in Fremont at 15MiB/sec... so WTF us up with Frankfurt→Fremont?! - Finally upload the 218 IITA items from March to CGSpace - Abenet and I had to do a little bit more work to correct the metadata of one item that appeared to be a duplicate, but really just had the wrong DOI - While I was uploading the IITA records I noticed that twenty of the records Sisay uploaded in 2018-09 had double Handles (`dc.identifier.uri`) - According to my notes in 2018-09 I had noticed this when he uploaded the records and told him to remove them, but he didn't... - I exported the IITA community as a CSV then used `csvcut` to extract the two URI columns and identify and fix the records: ``` $ csvcut -c id,dc.identifier.uri,'dc.identifier.uri[]' ~/Downloads/2019-04-24-IITA.csv > /tmp/iita.csv ``` - Carlos Tejo from the Land Portal had been emailing me this week to ask about the old REST API that Tsega was building in 2017 - I told him we never finished it, and that he should try to use the `/items/find-by-metadata-field` endpoint, with the caveat that you need to match the language attribute exactly (ie "en", "en_US", null, etc) - I asked him how many terms they are interested in, as we could probably make it easier by normalizing the language attributes of these fields (it would help us anyways) - He says he's getting HTTP 401 errors when trying to search for CPWF subject terms, which I can reproduce: ``` $ curl -f -H "accept: application/json" -H "Content-Type: application/json" -X POST "https://dspacetest.cgiar.org/rest/items/find-by-metadata-field" -d '{"key":"cg.subject.cpwf", "value":"WATER MANAGEMENT","language": "en_US"}' curl: (22) The requested URL returned error: 401 ``` - Note that curl only shows the HTTP 401 error if you use `-f` (fail), and only then if you *don't* include `-s` - I see there are about 1,000 items using CPWF subject "WATER MANAGEMENT" in the database, so there should definitely be results - The breakdown of `text_lang` fields used in those items is 942: ``` dspace=# SELECT COUNT(text_value) FROM metadatavalue WHERE resource_type_id=2 AND metadata_field_id=208 AND text_value='WATER MANAGEMENT' AND text_lang='en_US'; count ------- 376 (1 row) dspace=# SELECT COUNT(text_value) FROM metadatavalue WHERE resource_type_id=2 AND metadata_field_id=208 AND text_value='WATER MANAGEMENT' AND text_lang=''; count ------- 149 (1 row) dspace=# SELECT COUNT(text_value) FROM metadatavalue WHERE resource_type_id=2 AND metadata_field_id=208 AND text_value='WATER MANAGEMENT' AND text_lang IS NULL; count ------- 417 (1 row) ``` - I see that the HTTP 401 issue seems to be a bug due to an item that the user doesn't have permission to access... from the DSpace log: ``` 2019-04-24 08:11:51,129 INFO org.dspace.rest.ItemsResource @ Looking for item with metadata(key=cg.subject.cpwf,value=WATER MANAGEMENT, language=en_US). 2019-04-24 08:11:51,231 INFO org.dspace.usage.LoggerUsageEventListener @ anonymous::view_item:handle=10568/72448 2019-04-24 08:11:51,238 INFO org.dspace.usage.LoggerUsageEventListener @ anonymous::view_item:handle=10568/72491 2019-04-24 08:11:51,243 INFO org.dspace.usage.LoggerUsageEventListener @ anonymous::view_item:handle=10568/75703 2019-04-24 08:11:51,252 ERROR org.dspace.rest.ItemsResource @ User(anonymous) has not permission to read item! ``` - Nevertheless, if I request using the `null` language I get 1020 results, plus 179 for a blank language attribute: ``` $ curl -s -H "Content-Type: application/json" -X POST "https://dspacetest.cgiar.org/rest/items/find-by-metadata-field" -d '{"key":"cg.subject.cpwf", "value":"WATER MANAGEMENT","language": null}' | jq length 1020 $ curl -s -H "Content-Type: application/json" -X POST "https://dspacetest.cgiar.org/rest/items/find-by-metadata-field" -d '{"key":"cg.subject.cpwf", "value":"WATER MANAGEMENT","language": ""}' | jq length 179 ``` - This is weird because I see 942–1156 items with "WATER MANAGEMENT" (depending on wildcard matching for errors in subject spelling): ``` dspace=# SELECT COUNT(text_value) FROM metadatavalue WHERE resource_type_id=2 AND metadata_field_id=208 AND text_value='WATER MANAGEMENT'; count ------- 942 (1 row) dspace=# SELECT COUNT(text_value) FROM metadatavalue WHERE resource_type_id=2 AND metadata_field_id=208 AND text_value LIKE '%WATER MANAGEMENT%'; count ------- 1156 (1 row) ``` - I sent a message to the dspace-tech mailing list to ask for help ## 2019-04-25 - Peter pointed out that we need to remove Delicious and Google+ from our social sharing links - Also, it would be nice if we could include the item title in the shared link - I created an issue on GitHub to track this ([#419](https://github.com/ilri/DSpace/issues/419)) - I tested the REST API after logging in with my super admin account and I was able to get results for the problematic query: ``` $ curl -f -H "Content-Type: application/json" -X POST "https://dspacetest.cgiar.org/rest/login" -d '{"email":"example@me.com","password":"fuuuuu"}' $ curl -f -H "Content-Type: application/json" -H "rest-dspace-token: b43d41a6-5ac1-455d-b49a-616b8debc25b" -X GET "https://dspacetest.cgiar.org/rest/status" $ curl -f -H "rest-dspace-token: b43d41a6-5ac1-455d-b49a-616b8debc25b" -H "Content-Type: application/json" -X POST "https://dspacetest.cgiar.org/rest/items/find-by-metadata-field" -d '{"key":"cg.subject.cpwf", "value":"WATER MANAGEMENT","language": "en_US"}' ``` - I created a normal user for Carlos to try as an unprivileged user: ``` $ dspace user --add --givenname Carlos --surname Tejo --email blah@blah.com --password 'ddmmdd' ``` - But still I get the HTTP 401 and I have no idea which item is causing it - I enabled more verbose logging in `ItemsResource.java` and now I can at least see the item ID that causes the failure... - The item is not even in the archive, but somehow it is discoverable ``` dspace=# SELECT * FROM item WHERE item_id=74648; item_id | submitter_id | in_archive | withdrawn | last_modified | owning_collection | discoverable ---------+--------------+------------+-----------+----------------------------+-------------------+-------------- 74648 | 113 | f | f | 2016-03-30 09:00:52.131+00 | | t (1 row) ``` - I tried to delete the item in the web interface, and it seems successful, but I can still access the item in the admin interface, and nothing changes in PostgreSQL - Meet with CodeObia to see progress on AReS version 2 - Marissa Van Epp asked me to add a few new metadata values to their Phase II Project Tags field (cg.identifier.ccafsprojectpii) - I created a [pull request](https://github.com/ilri/DSpace/pull/420) for it and will do it the next time I run updates on CGSpace - Communicate with Carlos Tejo from the Land Portal about the `/items/find-by-metadata-value` endpoint - Run all system updates on DSpace Test (linode19) and reboot it ## 2019-04-26 - Export a list of authors for Peter to look through: ``` dspace=# \copy (select distinct text_value, count(*) as count from metadatavalue where metadata_field_id = (select metadata_field_id from metadatafieldregistry where element = 'contributor' and qualifier = 'author') AND resource_type_id = 2 group by text_value order by count desc) to /tmp/2019-04-26-all-authors.csv with csv header; COPY 65752 ``` ## 2019-04-28 - Still trying to figure out the issue with the items that cause the REST API's `/items/find-by-metadata-value` endpoint to throw an exception - I made the item private in the UI and then I see in the UI and PostgreSQL that it is no longer discoverable: ``` dspace=# SELECT * FROM item WHERE item_id=74648; item_id | submitter_id | in_archive | withdrawn | last_modified | owning_collection | discoverable ---------+--------------+------------+-----------+----------------------------+-------------------+-------------- 74648 | 113 | f | f | 2019-04-28 08:48:52.114-07 | | f (1 row) ``` - And I tried the `curl` command from above again, but I still get the HTTP 401 and and the same error in the DSpace log: ``` 2019-04-28 08:53:07,170 ERROR org.dspace.rest.ItemsResource @ User(anonymous) has not permission to read item(id=74648)! ``` - I even tried to "expunge" the item using an [action in CSV](https://wiki.lyrasis.org/display/DSDOC5x/Batch+Metadata+Editing#BatchMetadataEditing-Performing'actions'onitems), and it said "EXPUNGED!" but the item is still there... ## 2019-04-30 - Send mail to the dspace-tech mailing list to ask about the item expunge issue - Delete and re-create Podman container for dspacedb after pulling a new PostgreSQL container: ``` $ podman run --name dspacedb -v dspacedb_data:/var/lib/postgresql/data -e POSTGRES_PASSWORD=postgres -p 5432:5432 -d postgres:9.6-alpine ``` - Carlos from LandPortal asked if I could export CGSpace in a machine-readable format so I think I'll try to do a CSV - In order to make it easier for him to understand the CSV I will normalize the text languages (minus the provenance field) on my local development instance before exporting: ``` dspace=# SELECT DISTINCT text_lang, count(*) FROM metadatavalue WHERE resource_type_id = 2 AND metadata_field_id != 28 GROUP BY text_lang; text_lang | count -----------+--------- | 358647 * | 11 E. | 1 en | 1635 en_US | 602312 es | 12 es_ES | 2 ethnob | 1 fr | 2 spa | 2 | 1074345 (11 rows) dspace=# UPDATE metadatavalue SET text_lang='en_US' WHERE resource_type_id=2 AND metadata_field_id != 28 AND text_lang IN ('ethnob', 'en', '*', 'E.', ''); UPDATE 360295 dspace=# UPDATE metadatavalue SET text_lang='en_US' WHERE resource_type_id=2 AND metadata_field_id != 28 AND text_lang IS NULL; UPDATE 1074345 dspace=# UPDATE metadatavalue SET text_lang='es_ES' WHERE resource_type_id=2 AND metadata_field_id != 28 AND text_lang IN ('es', 'spa'); UPDATE 14 ``` - Then I exported the whole repository as CSV, imported it into OpenRefine, removed a few unneeded columns, exported it, zipped it down to 36MB, and emailed a link to Carlos - In other news, while I was looking through the CSV in OpenRefine I saw lots of weird values in some fields... we should check, for example: - issue dates - items missing handles - authorship types
