Instead of keeping Runtime and manually spawn a task on `drop` this task is spawned at start and will wait to be triggered.
The `drop` methods then wait for completion, UNLESS they are in a async context, then they MUST NOT BLOCK (deadlock potential), so they defer it to the Runtime and HOPE for the runtime to exist long enough.
This get rid of the weird `block_in_place` which is only accessable with `rt-multi-threaded` and has some disadvantages.
We also wont requiere the runtime to be active all the time. Though its needed for a clean shutdown
- now last digit version is compatible 0.6.0 will connect to 0.6.1
- the TCP DATA Frames no longer contain START field, as it's not needed
- the TCP OPENSTREAM Frames will now contain the BANDWIDTH field
- MID is not Protocol internal
Update network
- update API with Bandwidth
Update veloren
- introduce better runtime and `async` things that are IO bound.
- Remove `uvth` and instead use `tokio::runtime::Runtime::spawn_blocking`
- remove futures_execute from client and server use tokio::runtime::Runtime instead
- give threads a Name
- completly switch to Bytes, even in api. speed up TCP by fak 2
- improve benchmarks
- speed up mpsc metrics
- gracefully handle shutdown by interpreting Ok(0) as tokio::tcpstream closed now.
- fix hotloop in participants by adding `Some(n)` to fix endless handing.
- fix closing bug by closing streams after `recv_mgr` is shutdown even if now shutdown is triggered locally.
- fix prometheus
- no longer throw when a `Stream` is dropped while participant still receives a msg for it.
- fix the bandwith handling, TCP network send speed is up to 1.5GiB/s while recv is 150MiB/s
- add documentation
- tmp require rt-multi-threaded in client for tokio, to not fail cargo check
this is prob stable, i tested over 1 hour.
after that some optimisations in priomgr.
and impl. propper bandwith.
Speed is up to 2GB/s write and 150MB/s recv on a single core
sync add documentation
- better logging in network
- we now notify the send of what happened in recv in participant.
- works with veloren master servers
- works in singleplayer, using a actual mid.
- add `mpsc` in whole stack incl tests
- speed up internal read/write with `Bytes` crate
- use `prometheus-hyper` for metrics
- use a metrics cache
switch to `tokio` and `async_channel` crate.
I wanted to do tokio first, but it doesnt feature Sender::close(), thus i included async_channel
Got rid of `futures` and only need `futures_core` and `futures_util`.
Tokio does not support `Stream` and `StreamExt` so for now i need to use `tokio-stream`, i think this will go in `std` in the future
Created `b2b_close_stream_opened_sender_r` as the shutdown procedure does not need a copy of a Sender, it just need to stop it.
Various adjustments, e.g. for `select!` which now requieres a `&mut` for oneshots.
Future things to do:
- Use some better signalling than oneshot<()> in some cases.
- Use a Watch for the Prio propergation (impl. it ofc)
- Use Bounded Channels in order to improve performance
- adjust tests coding
bring tests to work
Refactor the `send_raw` and `recv_raw` completly. We now expost `Message` which has a public `serialize` and `deseialize` fn for the first time.
This makes using the `raw` methods of a stream much easier and is a requierement for using "copy_less" sending to multiple streams
