Releases: paritytech/jsonrpsee
v0.20.4
v0.24.3
[v0.24.3] - 2024-08-14
This is a small release that adds two new APIs to inject data via the extensions to the RpcModule/Methods
and it only impacts users that are using RpcModule directly via Methods::call/subscribe/raw_json_request
(e.g., unit testing) and not the server itself.
[Added]
- feat(server): add
Methods::extensions/extensions_mut
(#1440)
Full Changelog: v0.24.2...v0.24.3
v0.24.2
[v0.24.2] - 2024-08-02
Another small release that fixes:
- Notifications without params were not handled correctly in the client, which been has been fixed.
- Improve compile times and reduce code-generation in the proc macro crate.
[Fixed]
Thanks to the external contributor @DaniPopes who contributed to this release.

v0.24.1
[v0.24.1] - 2024-07-30
This is a small release that forces jsonrpsee rustls
to use the crypto backend ring which may panic if both ring
and aws-lc
features are enabled. See rustls/rustls#1877 for further information.
This has no impact on the default configuration of jsonrpsee which was already using ring
as the default.
[Changed]
- chore(deps): update gloo-net requirement from 0.5.0 to 0.6.0 (#1428)
[Fixed]
- fix: Explicitly set rustls provider before using rustls (#1424)
Full Changelog: v0.24.0...v0.24.1
v0.24.0
[v0.24.0] - 2024-07-05
A breaking release that mainly changes:
tls
feature for the client has been divided intotls
andtls-platform-verifier
where thetls
feature
will only includerustls
and no specific certificate store but the default one is stilltls-rustls-platform-verifier
.
This is useful if one wants to avoid bring on openssl dependencies.- Remove dependencies
anyhow
andbeef
from the codebase.
[Changed]
v0.23.2
[v0.23.2] - 2024-06-26
This a small patch release that fixes a couple of bugs and adds a couple of new APIs.
The bug fixes are:
- The
server::ws::on_connect
was not working properly due to a merge nit when upgrading to hyper v1.0
This impacts only users that are using the low-level API and not the server itself. WsTransport::build_with_stream
shouldn't not resolve the socket addresses and it's fixed now, see #1411 for further info.
This impacts users that are injecting their own TcpStream directly into theWsTransport
.
[Added]
- server: add
RpcModule::remove
(#1416) - server: add
capacity and max_capacity
to the subscription API (#1414) - server: add
PendingSubscriptionSink::method_name
(#1413)
[Fixed]
- server: make
ws::on_connect
work again (#1418) - client:
WsTransport::build_with_stream
don't resolve sockaddrs (#1412)
Full Changelog: v0.23.1...v0.23.2
v0.23.1
[v0.23.1] - 2024-06-10
This is a patch release that injects the ConnectionId in
the extensions when using a RpcModule without a server. This impacts
users that are using RpcModule directly (e.g., unit testing) and not the
server itself.
[Changed]
- types: remove anyhow dependency (#1398)
[Fixed]
- rpc module: inject ConnectionId in extensions (#1399)
Full Changelog: v0.23.0...v0.23.1
v0.23.0
[v0.23.0] - 2024-06-07
This is a new breaking release, and let's go through the changes.
hyper v1.0
jsonrpsee has been upgraded to use hyper v1.0 and this mainly impacts users that are using
the low-level API and rely on the hyper::service::make_service_fn
which has been removed, and from now on you need to manage the socket yourself.
The hyper::service::make_service_fn
can be replaced by the following example template:
async fn start_server() {
let listener = tokio::net::TcpListener::bind("127.0.0.1:0").await.unwrap();
loop {
let sock = tokio::select! {
res = listener.accept() => {
match res {
Ok((stream, _remote_addr)) => stream,
Err(e) => {
tracing::error!("failed to accept v4 connection: {:?}", e);
continue;
}
}
}
_ = per_conn.stop_handle.clone().shutdown() => break,
};
let svc = tower::service_fn(move |req: hyper::Request<hyper::body::Incoming>| {
let mut jsonrpsee_svc = svc_builder
.set_rpc_middleware(rpc_middleware)
.build(methods, stop_handle);
// https://github.com/rust-lang/rust/issues/102211 the error type can't be inferred
// to be `Box<dyn std::error::Error + Send + Sync>` so we need to convert it to a concrete type
// as workaround.
jsonrpsee_svc
.call(req)
.await
.map_err(|e| anyhow::anyhow!("{:?}", e))
});
tokio::spawn(jsonrpsee::server::serve_with_graceful_shutdown(
sock,
svc,
stop_handle.clone().shutdown(),
));
}
}
Also, be aware that tower::service_fn
and hyper::service::service_fn
are different and it's recommended to use tower::service_fn
from now.
Extensions
Because it was not possible/easy to share state between RPC middleware layers
jsonrpsee has added Extensions
to the Request and Response.
To allow users to inject arbitrary data that can be accessed in the RPC middleware
and RPC handlers.
Please be careful when injecting large amounts of data into the extensions because
It's cloned for each RPC call, which can increase memory usage significantly.
The connection ID from the jsonrpsee-server is injected in the extensions by default.
and it is possible to fetch it as follows:
struct LogConnectionId<S>(S);
impl<'a, S: RpcServiceT<'a>> RpcServiceT<'a> for LogConnectionId<S> {
type Future = S::Future;
fn call(&self, request: jsonrpsee::types::Request<'a>) -> Self::Future {
let conn_id = request.extensions().get::<ConnectionId>().unwrap();
tracing::info!("Connection ID {}", conn_id.0);
self.0.call(request)
}
}
In addition the Extensions
is not added in the proc-macro API by default and
one has to enable with_extensions
attr for that to be available:
#[rpc(client, server)]
pub trait Rpc {
// legacy
#[method(name = "foo"])
async fn async_method(&self) -> u16>;
// with extensions
#[method(name = "with_ext", with_extensions)]
async fn f(&self) -> bool;
}
impl RpcServer for () {
async fn async_method(&self) -> u16 {
12
}
// NOTE: ext is injected just after self in the API
async fn f(&self, ext: &Extensions: b: String) -> {
ext.get::<u32>().is_ok()
}
}
client - TLS certificate store changed
The default TLS certificate store has been changed to
rustls-platform-verifier
to decide the best certificate
store for each platform.
In addition it's now possible to inject a custom certificate store
if one wants need some special certificate store.
client - Subscription API modified
The subscription API has been modified:
- The error type has been changed to
serde_json::Error
to indicate that error can only occur if the decoding of T fails. - It has been some confusion when the subscription is closed which can occur if the client "lagged" or the connection is closed.
Now it's possible to callSubscription::close_reason
after the subscription closed (i.e. has return None) to know why.
If one wants to replace old messages in case of lagging it is recommended to write your own adaptor on top of the subscription:
fn drop_oldest_when_lagging<T: Clone + DeserializeOwned + Send + Sync + 'static>(
mut sub: Subscription<T>,
buffer_size: usize,
) -> impl Stream<Item = Result<T, BroadcastStreamRecvError>> {
let (tx, rx) = tokio::sync::broadcast::channel(buffer_size);
tokio::spawn(async move {
// Poll the subscription which ignores errors
while let Some(n) = sub.next().await {
let msg = match n {
Ok(msg) => msg,
Err(e) => {
tracing::error!("Failed to decode the subscription message: {e}");
continue;
}
};
// Only fails if the receiver has been dropped
if tx.send(msg).is_err() {
return;
}
}
});
BroadcastStream::new(rx)
}

cancel-safe.
