before, cache would clone the underlying object every time it was
accessed. this was definitely incredibly wasteful! now it clones the
Arc, which is super cheap. the extra work necessary while fetching
things is most likely more than compensated by saved clones every time
we render stuff. there is some dumb arc creation here and there (like
for the debug page), but it's mostly my lazyness, they can probably go
and should not be that much of a big deal anyway.
TLDR things were already fast but should be EVEN FASTER!!!
it shows it in quite a jank way: inside the "audience" collections you
find your id as only item. it's weird af but technically valid ap i
think? will probably be replaced with a local api extension as soon as i
read about those
use audience for followers, generator for following and replies for
total statuses count. restored followers, following and outbox as bare
links. silly AP!!!
basically relays send us a lot of announce activities to share posts
but we don't care about those activities: it's db bloat and it increases
the shares count. keep a table keeping track of followed relays and
lazily skip activities by them, just fetch. IMPORTANT relays are only
loaded at startup, so if you subscribe to a new relay restart your
server once it accepts!!!
i think because the db would end up locked, added brackets to be sure to
drop the streaming reference. also it could crash when updating records
not found, just spit a warn
note that won't reset everything to 0, just force set every post which
has a count != 0
also this is kind of a bad way to do it. at least we stream objects, but
we could have it happen all inside our db with SELECT, DISTINCT and SUM,
i just don't know how to represent it in sea_orm. an intermediate
optimization may be selecting only certain columns but it's relevant
almost only for replies
it's done with anonymous inline collections, which hold a "totalItems"
field. for replies it's perfect, for likes it's stretched ("audience",
used as a Collection) and for shares it's really stretched ("generator",
used as a Collection). also using audience and generator as collections
seems weird because they should be objects but collections are objects
so it should be fine? i haven't seen these fields used anyway so it
should be safe to "claim" it for ourselves?
for example, pleroma servers objects under /notice/abcd... but the
object id itself is different, under /objects/<uuid>. when fetching
pleroma redirects, but we get unreliable behavior. redirect so that we
can force clients to use the proper id
basically now object.as_actor() or object.as_collection() returns an
option which is full with a self ref only if the type is correct, so
that we can assume flexible json behavior from anything implementing our
apb traits, and we don't need to rely anymore on knowing the underlying
type
also little import refactor
this happens because we're paginating with just an offset, meaning that
when new activities get inserted that offset "gets shifted forward" and
we receive again some activities we saw already. this should get fixed
for good on the backend, but for now discarding them here makes it
usable
