It's seems right that we should have a local community to help us all with PieFed

How come this Lemmy community only shows the last 15 posts / 10 months worth of posts on Piefed?

This community or this community (from the same Lemmy instance) too are clipped, but they both show a year's worth.

Does it have something to do with the date at which the first PieFed user join them?

I know Lemmy instances only start mirroring a community hosted on another instance when someone on that instance joins it. But after that someone joined and the instance is done mirroring the community, the whole of it is browseable.

If I had to guess, I'd say Piefed instances only mirror the 15 last posts after the first user joins, or a years's worth, whichever applies. Correct?

And if so, does this also apply to native Piefed communities? In other words, does Piefied "disappear" older posts in Piefed communities?

@rimu@piefed.social might be able to answer better and more specifically since he is the admin for piefed.social, but here is some info on what might be happening.

Federation in piefed works the same as it does in lemmy...in that piefed won't get posts for a community unless a local user is subscribed to it (lemmy provides the most recent 20 posts to an instance when the first subscriber joins). So, until a user from piefed.social subscribed to those communities, then no posts would show up. As a corollary to this, if there is one local subscriber that then unsubscribes, posts will stop federating over. So, that can cause things like gaps in federation.

As for automatic deletion of older posts...this is something that a piefed admin can do on a community by community basis. When it is turned on for a community, that retention policy is listed in the community sidebar. For instance, if you look at the sidebar of !anime@ani.social, you will see that posts are retained on piefed.social for 365 days.

The communities you have listed don't have a retention policy in the sidebar, so I don't believe this is the issue. Most likely it is due to federation not starting until a certain point.

I know that rimu was actively working on an archiving feature for piefed, but I think this feature isn't live yet. The archiving would basically "archive" old posts in object storage instead of deleting them. So, if somebody does try to load up an old post, it might take a hair longer to load as it is unarchived, but it wouldn't be deleted and inaccessible.

Okay then it's fine. I was afraid it was a compulsory thing. I wouldn't consider importing my Lemmy communities on Piefed if it forgot old post.

Pulling in those 50 posts works most of the time but sometimes, for unknown reasons, it fails and only some posts get mirrored.

Okay. Well I was just curious. I suppose all the posts will show up after I migrate the communities over here.

Thanks!

Community migration doesn't backfill like this. Instead, it simply reassigns all the posts that the instance has in the old community to the newly migrated community. So, if there are important posts/comments that aren't federated over yet, you should force that federation before going through the migration.

To force federation of a post/comment in piefed, go to the community on its home instance and locate the post/comment that you want to bring into piefed. Copy the canonical link from that post comment. This is the link that the little fediverse icon points to (it's a little version of this logo):

Then, go over to the community on piefed, and near the bottom of the sidebar, there is a link to "Retrieve a post from the original server". Click that and paste in that canonical link you grabbed. Piefed should go out and pull over the post/comment that the link points to. One thing to note is that you can't pull a comment that is a reply to another comment without first pulling what it is in reply to.

Some posts seem to not be retrievable, yet they exist when you follow the canonical links and the Lemmy instances aren't blocvked.

This one for instance:

https://pawb.social/comment/13985010

Any idea why?

[–] wjs018@piefed.social 2 points 5 days ago (1 children)

That case would be because piefed.social is defederated from pawb.social, preventing the federation.

Right okay I undertand. Thanks!
