As you may have noticed, the crawler at https://lemmyverse.net isn't picking up anything from instances on versions 0.19.4 or 0.19.5.

The Issue itself is easily fixed, and there's already a PR for it from lemm.ee's admin, but there's been no response from the lemmyverse developer.

Does anyway have any other ways of contacting him?
If this continues (I realise 2 weeks isn't that long), is anyone interested in forking the code and hosting it on a new domain?

Thanks.

When I've mentioned this issue to admins at lemmy.ca and endlesstalk.org (relevant posts here and here), they've suggested it's a misconfiguration. When I said the same to lemmy.world admins (relevant comment here), they also suggested it was misconfig. I mentioned it again recently on the LW channel, and it was only then was Lemmy itself proposed as a problem. It happens on plenty of servers, but not all of them, so I don't know where the fault lies.

A bug report for software I don't run, and so can't reproduce would be closed anyway. I think 'steps to reproduce' is pretty much the first line in a bug report.

If I ran a server that used someone else's software to allow users to download a file, and someone told me that every 2nd byte needed to be discarded, I like to think I'd investigate and contact the software vendors if required. I wouldn't tell the user that it's something they should be doing. I feel like I'm the user in this scenario.

They'll all POST requests. I trimmed it out of the log for space, but the first 6 requests on the video looked like (nginx shows the data amount for GET, but not POST):

ip.address - - [07/Apr/2024:23:18:44 +0000] "POST /inbox HTTP/1.1" 200 0 "-" "Lemmy/0.19.3; +https://lemmy.world"
ip.address- - [07/Apr/2024:23:18:44 +0000] "POST /inbox HTTP/1.1" 200 0 "-" "Lemmy/0.19.3; +https://lemmy.world"
ip.address - - [07/Apr/2024:23:19:14 +0000] "POST /inbox HTTP/1.1" 200 0 "-" "Lemmy/0.19.3; +https://lemmy.world"
ip.address - - [07/Apr/2024:23:19:14 +0000] "POST /inbox HTTP/1.1" 200 0 "-" "Lemmy/0.19.3; +https://lemmy.world"
ip.address - - [07/Apr/2024:23:19:44 +0000] "POST /inbox HTTP/1.1" 200 0 "-" "Lemmy/0.19.3; +https://lemmy.world"
ip.address - - [07/Apr/2024:23:19:44 +0000] "POST /inbox HTTP/1.1" 200 0 "-" "Lemmy/0.19.3; +https://lemmy.world"

If I was running Lemmy, every second line would say 400, from it rejecting it as a duplicate. In terms of bandwidth, every line represents a full JSON, so I guess it's about 2K minimum for the standard cruft, plus however much for the actual contents of comment (the comment replying to this would've been 8K)

My server just took the requests and dumped the bodies out to a file, and then a script was outputting the object.id, object.type and object.actor into /tmp/demo.txt (which is another confirmation that they were POST requests, of course)

I can't re-produce anything, because I don't run Lemmy on my server. It's possible to infer that's it's related to the software (because LW didn't do this when it was on 0.18.5). However, it's not something that, for example, lemmy.ml does. An admin on LW matrix chat suggested that it's likely a combination of instance configuration and software changes, but a bug report from me (who has no idea how LW is set up) wouldn't be much use.

I'd gently suggest that, if LW admins think it's a configuration problem, they should talk to other Lemmy admins, and if they think Lemmy itself plays a role, they should talk to the devs. I could be wrong, but this has been happening for a while now, and I don't get the sense that anyone is talking to anyone about it.

I realise this is a known issue and that lemmy.world isn't the only instance that does this. Also, I'm aware that there are other things affecting federation. But I'm seeing some things not federate, and can't help thinking that things would be going smoother if all the output from the biggest lemmy instance wasn't 50% spam.

Hopefully this doesn't seem like I'm shit-stirring, or trying to make the Issue I'm interested in more important than other Issues. It's something I mention occasionally, but it might be a bit abstract if you're not the admin of another instance.

The red terminal is a tail -f of the nginx log on my server. The green terminal is outputting some details from the ActivityPub JSON containing the Announce. You should be able to see the correlation between the lines in the nginx log, and lines from the activity, and that everything is duplicated.

This was generated by me commenting on an old post, using content that spawns an answer from a couple of bots, and then me upvoting the response. (so CREATE, CREATE, LIKE, is being announced as CREATE, CREATE, CREATE, CREATE, LIKE, LIKE). If you scale that up to every activity by every user, you'll appreciate that LW is creating a lot of work for anyone else in the Fediverse, just to filter out the duplicates.

For anyone unaware, a community's outbox typically contains the last 50 or so Post Announcements - it is retrieved when you are the first person to find a community on a remote instance. It also seems to be fetched whenever an community on a remote instance realizes it's out of sync with the community on its host instance.

Compare:

curl --header 'accept: application/json' https://lemmy.world/c/memes | jq -r .outbox           
=> https://lemmy.world/c/memes/outbox                
curl --header 'accept: application/json' https://lemmy.world/c/memes/outbox | jq .       
{
  "error": "unknown",
  "message": "Record not found"
}

with

curl --header 'accept: application/json' https://lemmy.world/c/linuxmemes | jq -r .outbox      
=> https://lemmy.world/c/linuxmemes/outbox          
curl --header 'accept: application/json' https://lemmy.world/c/linuxmemes/outbox | jq .orderedItems[0]   
{   
    "id": "https://lemmy.world/activities/announce/create/0223f939-aafc-4215-9c20-a3460c967f63" 
    ... (the rest of the most recent post from linux memes)
}

(I came across this randomly, so I don't know if 'memes' is the only community missing an outbox. Others I've tried have been OK though)

Hi

Pls check how much traffic you're now sending out for every activity - my server is recording that everything from lemmy.world is being 4 times (e.g. 1 Upvote is sent 4 times to every instance that has a subscriber. Those instances will reject 3 of them for being dupes, but it's still a lot to be sending out).

lemmy.ca had a problem where they were sending everything 3 times, and it was because they were running 3 containers, and they all had the same index number, so maybe it's that.

Thanks.

Hello again,

February's finally over, so 4 Frame memes are old news. Now, for March, memes with rhymes in them are what's required to get Featured in the Community.

This one will be stickied until a new meme with (ideally terrible) rhymes in and [ILPM] somewhere in the title is submitted, and then the new post will be stickied instead (it's a manual affair atm, so it won't be instant)

Thanks!

Shift ends in 10 minutes? Whatever it is, it's been the next shift's problem for 50 minutes already.

They've already replied with the reasons, but - for future reference - if you want to see specifics of things like this, a censure is often posted to https://fediseer.com. .world's censure of .nl is here

Yes, you're right. This is the format I was looking for.

Metric stormtroopers are about a meter off-target, but Imperial ones are only about a yard, so they're a minor improvement.

A repost, huh? Well I'll repost a repost inside your repost!
