"allow-duplicate-queries" seems to work partially

[stalkerGH]

Hi wiktorn.

I'm fighting with Overpass API local installation from your Docker image. After long debugging I realized that the package I'm using in R falis (probably) because of duplicate queries in dispatcher. I stopped and removed Docker container, then pulled most current image using docker pull wiktorn/overpass-api:latest. I checked files in Docker Desktop and they seem to contain the fixes you have made from PR rom @lukey78.

Then I started docker by this command:

docker run \
      -e OVERPASS_META=no \
      -e OVERPASS_MODE=init \
      -e OVERPASS_PLANET_URL=http://download.geofabrik.de/europe/poland-latest.osm.bz2 \
      -e OVERPASS_DIFF_URL=http://download.openstreetmap.fr/replication/europe/poland/minute/ \
      -e OVERPASS_RULES_LOAD=10 \
      -e OVERPASS_UPDATE_SLEEP=3600 \
      -e OVERPASS_USE_AREAS=true\
      -e OVERPASS_ALLOW_DUPLICATE_QUERIES=yes \
      -v /home/stalker/.docker/overpassAPI-poland:/db \
     -p 8888:80 \
     -i -t \
     --name overpass_poland \
     wiktorn/overpass-api

But I see in log:

127.0.0.1 - - [19/Dec/2023:12:49:58 +0000] "GET /api/interpreter?data=[out:json];node(1);out; HTTP/1.1" 200 296 "-" "curl/7.74.0"

So is the shuffling working? If I understand what docker-healthcheck.sh does, every time node number should be different.

If I paste http://127.0.0.1:8888/api/interpreter?data=%5Bout:json%5D;node(1);out; to browser address bar and press ENTER, I got error message:

Error: runtime error: open64: 0 Success /osm3s_osm_base Dispatcher_Client::request_read_and_idx::duplicate_query

But if I change node(1) to random number, eg. node(9359), I got:

{ "version": 0.6, "generator": "Overpass API 0.7.61 980f0092", "osm3s": { "timestamp_osm_base": "2023-12-19T08:21:45Z", "copyright": "The data included in this document is from www.openstreetmap.org. The data is made available under ODbL." }, "elements": [

] }

What I'm doing wrong then?

@stalkerGH Strange - for me the problem stopped, but I have not yet switched to the new official image. Can you try with my fork on Dockerhub my pull request was based on?

jhassler/overpass-api:0.7.61.8

I can maybe look into that on the weekend.

Hi. Thanks for reply. I'll try and give feedback.

[stalkerGH]

@lukey78 I'm puzzled. Should I add OVERPASS_HEALTHCHECK to Docker call...?

EDIT: I didn't understand how the docker-healtcheck.sh script works but everything is clear now. If I have the OVERPASS_ALLOW_DUPLICATE_QUERIES=yes option in the Docker call, then the script will query node(1) all the time. If I set OVERPASS_ALLOW_DUPLICATE_QUERIES=no, then the node number is randomized.

Thank you :)

My problem is solved so I close ithe issue.

I have just tried this as well and can confirm that duplicate queries work using jhassler/overpass-api:0.7.61.8, but not using the wiktorn/overpass-api:latest. I think there is an issue with the new official image perhaps?

[wiktorn]

I did investigate that and I think I found the culprit.

wiktorn/overpass-api:latest is the same as wiktorn/overpass-api:0.7.61, and wiktorn/overpass-api:0.7.61.6

This version of Overpass might have a bug handing this argument. I guess that specifying explicitly wiktorn/overpass-api:0.7.61.8 should fix that.

@mmd-osm looking in Overpass releases I do see that osm-3s_v0.7.61.tar.gz has timestamp similar to osm-3s_v0.7.61.6.tar.gz. Is there a reason why it was not updated or this was just a omission during the release of 0.7.61.7 and 0.7.61.8?
