Federate content of a searched post or comment

[Fmstrat]

Requirements

• Is this a feature request? For questions or discussions use https://lemmy.ml/c/lemmy_support or the matrix chat.
• Did you check to see if this issue already exists?
• Is this only a feature request? Do not put multiple feature requests in one issue.
• Is this a backend issue? Use the lemmy-ui repo for UI / frontend issues.
• Do you agree to follow the rules in our Code of Conduct?

Is your proposal related to a problem?

Assumptions:

• I am browsing the web and come across a comment on a post on an instance that I would like to participate in
• My home instance may or may not be federated with this instance yet
• No user on my home instance is subscribed to the community
• Due to the above, the post does not exist on my instance

Action: Search post

• I search for the post on my home instance by putting in the URL of https://other.instance/post/1234
• The post and community are federated to my instance during the search, and the result pops up
• However, no comments or votes come over, so I am unable to respond to the initial comment

Describe the solution you'd like.

When searching for a post on another instance, that post should begin federating and backfill content. Preferably new content specific to that post would also federate if a user on the local instance interacts with it (comment/vote/save).

Describe alternatives you've considered.

Searching every individual comment fedilink, which is not really feasible.

Additional context

Apologies if this has come up before, I swear I saw something similar but less detailed a loooong time ago, but could not find it anywhere. I also don't think it was exactly this.

lemmy-ui changed comment links to include the post id. The old links (https://other.instance/comment/0987) still work.

Edit: The fedilink (next to comment direct link) still has the old format.

I'm not sure I know what you mean by "next to comment direct link" as I only see the one link, but searching for https://other.instance/comment/0987 does not work either. Content is not federated post search, and the comment is not pulled into the local server.

Edit: I have updated the report yo include that format as well.

Edit2: Found what you meant by Fedilink, but it too fails (same format as updated report).

@matc-pub Actually, that part may be a bug.

• Top-level comments from users on the same I instance as the post federate when you search the comment fedilink.
• No comments federate from users on another instance
• Lower level comments do not federate when searched, at least if the parent comment is not from the original instance

For instance, if I search a post that was made on lemm.ee it federates to my server. If I search a comment that was made on that post by a user on lemmy.world, it doesnt federate. It doesnt matter if you search the UI comment link or the fedilink.

I wonder if the local server doesn't think a parent exists because of the mismatch in host, even though that's valid.

Annnnd that may have been a one-off federation issue. Using the fedilink works every other time. Ugh, inconsistencies will be the death of me.

I am updating the above feature request to focus only on federating the content once a user has interacted.
