@nowster@fedi.nowster.me.uk Welcome to #snac 😉

@justine@snac.smithies.me.uk I notice that the current version of #pachli doesn't stop requesting the timeline when it refreshes. What I'll miss when I eventually migrate will be following hashtags.

@nowster @justine Thanks for the test account.
There are at least two #snac bugs.
I've filed one of them at https://codeberg.org/grunfink/snac2/issues/241 (this also found a Pachli bug where errors during login weren't showing the underlying login error; I've fixed that now, thanks).
The other is the existing https://codeberg.org/grunfink/snac2/issues/164 -- snac doesn't implement https://docs.joinmastodon.org/api/guidelines/#pagination so Mastodon clients can't iterate through timelines to load them a page at a time.

Hi, #snac author here. Thanks for reporting on the 'bot' account bug, I have to take a look at it.
Regarding the other issue, snac do support Mastodon API pagination. Many apps do this correctly, like Tusky, Fedilab or semaphore.social, so you can travel the full timeline. Other ones only request the first page, I don't know why.

Hi, #snac author here again. I've installed Pachli and I'm experimenting the same issue than @nowster@fedi.nowster.me.uk: it keeps requesting the first page over and over again, with no max_id nor since_id fields to paginate, only a limit field of 40.

@grunfink @nowster @justine The link header is not being sent by snac.
I have a test account with 4 statuses in the home timeline.
/api/v1/timelines/home returns all 4 statuses and no link header in the response.
/api/v1/timelines/home?limit=1 returns an array of 1 status, as expected, but is also missing the link header, so can't be paginated.

@grunfink @nowster @justine The Mastodon docs are a bit ambiguous about this. Arguably, if the link header is missing a client could assume it could behave as though it did exist, with the IDs of the first and last items in the returned page.
That might be what snac is doing. For interoperability purposes it's probably better to always return the link header.

Hi. I've just implemented the link header and Pachli seems to page correctly and not get stuck requesting the first page.
This will probably also improve snac behaviour with other apps.

Many apps work ok without the Link header kludge, they just keep track of the last seen post Id, and when they need more posts to be shown, they just use a max_id argument for the next page.
As you say, the Mastodon documentation is a bit ambiguous.
Anyway, I'll work on implementing it. Thanks for the conversation.
