Delete branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Description
I am using GET /_matrix/client/v3/sync to sync filtered by a certain user and using
since
to fetch latest state. I also set timeout to 30 seconds and repeat after it expires.Example
/_matrix/client/v3/sync?filter=sofW&since=425298&timeout=30000
When a message event is actually sent to an encrypted room where user is member of, instead of this message event being delivered with the current open sync GET request, it immediately returns with an empty timeline
and I have to repeat the exact same sync request to get the new timeline.
I checked documentation and I made an assumption that the
full_state
is maybe not respected cause of this:and therefore I tried to explicitly set it to false (
full_state=false
) but no difference.Is there a reason for that? To me it seems more like a bug rather than intended behavior.
System Configuration
Version: v0.6.0
Conduit Version:
Database backend (default is sqlite): sqlite
Yes I am aware of this /sync behavior. It is a bit weird and slightly less efficient and we should improve it in the future. Is it a problem for you in practice?
thank you Timo for the quick response. It has a latency impact and since we are trying to achieve max performance and min latency (we are considering using the messenger as means of exchanging messages in an automated way also between machines), it adds an overhead.
I would try to fork and figure it out but I have 0 rust knowledge :P
Do you maybe have an estimate?
