Note: maybe upgrading tokio helps against the connection issues, there is some mio related stuff: https://github.com/tokio-rs/tokio/releases/tag/tokio-1.18.0
Note: quick also still has the old read, but its more complicated, thus i only want to change it if its tested
We calculate a max bandwidth, but due to framing the packages, i think its possible for the current_bytes to get a few bytes over the actuall planed bandwidth. which prob isn't that bad/unfair
for that we need to create a socket2 socket and set_only_v6 to true.
We need to privude set_nonblocking for tokio to work and we need to set reuseaddr for it to work on linux systems
cannot update the following dependencies:
- vek: Sharps SIMD isnt upstream
- tracing-subscriber: MakeWriter was adjusted and i was to lazy to fiddle with lifetimes,
- refinery, rustsql: we have a custom refinery version which is incompatible with newer rustsql
- equi + egui_winit + egui_wgpu_backend: i tried it in this commit but it turned out that they dependo n wgpu which we cant update
- wgpu: cant update due new version doesnt support DX11
Got quinn updated which now require some dependencies to be explicit.
Increase the timeouts from 1000 -> 3000 ms if there are some internal messages send (e.g. network_a closed, send on stream_a)
Increase the timeouts from 1000 -> 5000 ms if there is actuall networking involed (e.g. stream_a send, stream_b recv)
The security model has been updated to reflect this change (for example,
moderators cannot revert a ban by an administrator). Ban history is
also now recorded in the ban file, and much more information about the
ban is stored (whitelists and administrators also have extra
information).
To support the new information without losing important information,
this commit also introduces a new migration path for editable settings
(both from legacy to the new format, and between versions). Examples
of how to do this correctly, and migrate to new versions of a settings
file, are in the settings/ subdirectory.
As part of this effort, editable settings have been revamped to
guarantee atomic saves (due to the increased amount of information in
each file), some latent bugs in networking were fixed, and server-cli
has been updated to go through StructOpt for both calls through TUI
and argv, greatly simplifying parsing logic.
When local SendProtocol is opening a Stream, it will send a empty message to QuicDrain which will then know that its time to open a quic stream.
It will open a QuicStream and send its SID over to remote.
The RecvStream will be send to local QuicSink
RemoteRecv will notice a new BiStream was opened and read its Sid. It will now start listening on it. while remote main will get the information that a stream was opened and will notice the frontend.
in participant remote Recv is synced with remote send (without triggering a empty message!).
RemoteRecv Sink will send the sendstream to RemoteSend Drain and it will be used when a first message is send on this stream.
- locally we open a stream, our local Drain is sending OpenStream
- remote Sink will know this and notify remote Drain
- remote side sends a message
- local sink does not know about the Stream. as there is (and CANT) be a wat to notify local Sink from local Drain (it could introduce race conditions).
One of the possible solutions was, that the remote drain will copy the OpenStream Msg ON the Quic::stream before first data is send. This would work but is complicated.
Instead we now just mark such streams as "potentially open" and we listen for the first DataHeader to get it's SID.
add support for unreliable messages in quic protocol, benchmarks
If its Closed it looks like the TCP connection got dropped/cut off (e.g. OS, Wifi).
If its Violated we for sure know the cause is the messages send/recv in a wrong way
Its available to `api` and `metrics` and can be used to slow down msg send in veloren.
It uses a tokio::watch for now, as i plan to have a watch job in the scheduler that recalculates prio on change.
Also cleaning up participant metrics after a disconnect
