The plan is to move all of the per-event checks into the
pdu_event_allowed function.
TODO: split the `visibility_filter` function into it's own commit. I
think this one was inherited from an earlier conduwuit commit.
As far as I can tell, 'filter.limit' and the 'limit' query parameter are
completely redundant. I've moved the 'take(limit)' call until after
filtering, to ensure that we can return up to 'limit' events even when
some are rejected by the filter. In a future commit, I will add a global
limit on loaded events to avoid DoS.
I really doubt anybody is sending /message requests with a filter that
rejects the entire request, but it's the first step in the filter
implementation.
Unfortunately we need to pull tracing-opentelemetry from git because
there hasn't been a release including the dependency bump on the other
opentelemetry crates.
This allows us to use the `ruma_route` convenience function even when we
need to add our own hacks into the responses, thus making us less
reliant on Ruma.
This change is fully automated, except the `rustfmt.toml` changes and
a few clippy directives to allow specific functions with too many lines
because they are longer now.
