charset=UTF-8 Content-Transfer-Encoding: 8bit * Moving rpc sidecar to event sidecar workspace. Both og those servers will work on one binary * Updating schemars version because the old one is having bugs (if there is a name collision for components schema only one will be saved) * Copying casper_types to this project. The reason is that casper_types in release <= 4.0.1 depends on old schemars * Copying casper_types for 2.0 release to this project. The reason is that rpc sidecar has to use the new types definitions, but for now they are not released (and it's not clear if they will be released prior to node 2.0 release). * Changing RpcError implementation to fix tests. Some alignments of codestyle to make clippy happy. * Moving casper-types dependencies to workspace level * Sync changes from node branch * Update the schema file * Delete protocol.md * Move a DbId fix * Change error message * Changes to versioning * Sync changes to types * Switch to having a single binary * Moving config files, fixing compilation issues * bump 'juliet' to '0.2.1' * Sync casper-types changes * Changing RPC sidecar config so that the rpc_server.node_client.exponential_backoff will take a new parameter called max_attempts. I tcan be either "infinite" or a positive, non-zero number. * Storing ApiVersion in event_log table. Removing is_big_integer_id config from DDLConfiguration because it's no longer needed (new version of sea_query handles the situation of defining big_integer and autoincrement) * Revert "Storing ApiVersion in event_log table. Removing is_big_integer_id con…" * Update for node review changes (#15) * Update for node changes * Fix lints * Cleanup * Cover all values in tag roundtrip tests * Moving admin server out from the sse sidecar. They are spinned up separately from sse events server. Also the database initialization happens separetely. Is sse events server is defined a storage definition is required. If rest api server is defined a storage definition is required. * Fix GlobalStateRequest::random * Changes explicit BoxFuture casting to calling 'boxed()' method --------- Co-authored-by: Jakub

+[![License](https://img.shields.io/badge/license-Apache-blue)](https://github.com/CasperLabs/casper-node/blob/master/LICENSE) + +## Synopsis + +The sidecar is a process that runs alongside the Casper node and exposes a JSON-RPC interface for interacting with the node. The RPC protocol allows for basic operations like querying global state, sending transactions and deploys etc. All of the RPC methods are documented [here](https://docs.casper.network/developers/json-rpc/). + +## Protocol +The sidecar maintains a TCP connection with the node and communicates using a custom binary protocol built on top of [Juliet](https://github.com/casper-network/juliet). The protocol uses a request-response model where the sidecar sends simple self-contained requests and the node responds to them. The requests can be split into these main categories: +- read requests + - queries for transient in-memory information like the + current block height, peer list, component status etc. + - queries for database items, with both the database and the key + always being explicitly specified by the sidecar +- execute transaction requests + - request to submit a transaction for execution + - request to speculatively execute a transaction + +The node does not interpret the data it sends where it's not necessary. For example, most database items are sent as opaque byte arrays and the sidecar is responsible for interpreting them. This leaves the sidecar in control of the data it receives and allows it to be more flexible in how it handles it. + +## License + +Licensed under the [Apache License Version 2.0](https://github.com/casper-network/casper-node/blob/master/LICENSE). diff --git a/rpc_sidecar/build.rs b/rpc_sidecar/build.rs new file mode 100644 index 00000000..820ad1ce --- /dev/null +++ b/rpc_sidecar/build.rs @@ -0,0 +1,16 @@ +use std::env; + +use vergen::EmitBuilder; + +fn main() { + if let Err(error) = EmitBuilder::builder().fail_on_error().git_sha(true).emit() { + println!("cargo:warning={}", error); + println!("cargo:warning=casper-rpc-sidecar build version will not include git short hash"); + } + + // Make the build profile available to rustc at compile time. + println!( + "cargo:rustc-env=SIDECAR_BUILD_PROFILE={}", + env::var("PROFILE").unwrap() + ); +} diff --git a/rpc_sidecar/src/config.rs b/rpc_sidecar/src/config.rs new file mode 100644 index 00000000..41cffd1a --- /dev/null +++ b/rpc_sidecar/src/config.rs @@ -0,0 +1,363 @@ +use std::{ + convert::{TryFrom, TryInto}, + net::{IpAddr, Ipv4Addr, SocketAddr}, +}; + +use datasize::DataSize; +use serde::Deserialize; +use thiserror::Error; + +use crate::SpeculativeExecConfig; + +/// Default binding address for the JSON-RPC HTTP server. +/// +/// Uses a fixed port per node, but binds on any interface. +const DEFAULT_ADDRESS: &str = "0.0.0.0:0"; +/// Default rate limit in qps. +const DEFAULT_QPS_LIMIT: u64 = 100; +/// Default max body bytes.

There are two checksums in the registry, one for the execution results and the other for the approvals of all deploys in the block. -* Add new `StoredValue::Unbonding` variant to support redelegating. -* Add a new type `WithdrawPurses` which is meant to represent `UnbondingPurses` as they exist in current live networks. - -### Changed -* Extend `UnbondingPurse` to take a new field `new_validator` which represents the validator to whom tokens will be re-delegated. -* Increase `DICTIONARY_ITEM_KEY_MAX_LENGTH` to 128. -* Change prefix of formatted string representation of `ContractPackageHash` from "contract-package-wasm" to "contract-package-". Parsing from the old format is still supported. -* Apply `#[non_exhaustive]` to error enums. -* Change Debug output of `DeployHash` to hex-encoded string rather than a list of integers. - -### Fixed -* Fix some integer casts, where failure is now detected and reported via new error variant `NotRepresentable`. - - - -## 2.0.0 - -### Fixed -* Republish v1.6.0 as v2.0.0 due to missed breaking change in API (addition of new variant to `Key`). - - - -## 1.6.0 [YANKED] - -### Added -* Extend asymmetric key functionality, available via feature `std` (moved from `casper-nodes` crate). -* Provide `Timestamp` and `TimeDiff` types for time operations, with extended functionality available via feature `std` (moved from `casper-nodes` crate). -* Provide test-only functionality, in particular a seedable RNG `TestRng` which outputs its seed on test failure. Available via a new feature `testing`. -* Add new `Key::EraSummary` key variant under which the era summary info is written on each switch block execution. - -### Deprecated -* Deprecate `gens` feature: its functionality is included in the new `testing` feature. - - - -## 1.5.0 - -### Added -* Provide types and functionality to support improved access control inside execution engine. -* Provide `CLTyped` impl for `ContractPackage` to allow it to be passed into contracts. - -### Fixed -* Limit parsing of CLTyped objects to a maximum of 50 types deep. - - - -## 1.4.6 - 2021-12-29 - -### Changed -* Disable checksummed-hex encoding, but leave checksummed-hex decoding in place. - - - -## 1.4.5 - 2021-12-06 - -### Added -* Add function to `auction::MintProvider` trait to support minting into an existing purse. - -### Changed -* Change checksummed hex implementation to use 32 byte rather than 64 byte blake2b digests. - - - -## [1.4.4] - 2021-11-18 - -### Fixed -* Revert the accidental change to the `std` feature causing a broken build when this feature is enabled. - - - -## [1.4.3] - 2021-11-17 [YANKED] - - - -## [1.4.2] - 2021-11-13 [YANKED] - -### Added -* Add checksummed hex encoding following a scheme similar to [EIP-55](https://eips.ethereum.org/EIPS/eip-55). - - - -## [1.4.1] - 2021-10-23 - -No changes. - - - -## [1.4.0] - 2021-10-21 [YANKED] - -### Added -* Add `json-schema` feature, disabled by default, to enable many types to be used to produce JSON-schema data. -* Add implicit `datasize` feature, disabled by default, to enable many types to derive the `DataSize` trait. -* Add `StoredValue` types to this crate. - -### Changed -* Support building and testing using stable Rust. -* Allow longer hex string to be presented in `json` files. Current maximum is increased from 100 to 150 characters. -* Improve documentation and `Debug` impls for `ApiError`. - -### Deprecated -* Feature `std` is deprecated as it is now a no-op, since there is no benefit to linking the std lib via this crate. - - - -## [1.3.0] - 2021-07-19 - -### Changed -* Restrict summarization when JSON pretty-printing to contiguous long hex strings. -* Update pinned version of Rust to `nightly-2021-06-17`. - -### Removed -* Remove ability to clone `SecretKey`s. -

Instead we wrap the sse events in an envelope which looks like: (#252) ``` { "header": { "api_version": "2.0.0", "network_name": "casper" }, "payload": {(...)} } ``` Events in endpoints that return lists (like signatures for block) will also have each individual element of the list wrapped in such envelope. In the above the header fields: * "api_version" is the api version which was reported in the ApiVersion message for the node that we fetched the event from. * "network_name" is the "chainspec_name" field that was returned in the "/status" endpoint for the node that we fetched the event from.

If configuration for all components is either missing or has `enable_server = false`, sidecar exits since it has nothing to do. Also did some refactoring of initialization code.

process. This reduces the load on the node process by allowing subscribers to monitor the event stream through the Sidecar while the node focuses entirely on the blockchain. Users needing access to the JSON-RPC will still need to query the node directly. +The Casper Event Sidecar is an application that runs in tandem with the node process. It's main purpose is to: +* offload the node from broadcasting SSE events to multiple clients +* provide client features that aren't part of the nodes' functionality, nor should they be While the primary use case for the Sidecar application is running alongside the node on the same machine, it can be run remotely if necessary. ### System Components & Architecture -![Sidecar Diagram](/images/SidecarDiagram.png) - -Casper Nodes offer a Node Event Stream API returning Server-Sent Events (SSEs) that hold JSON-encoded data. The SSE Sidecar uses this API to achieve the following goals: - -* Build a sidecar middleware service that reads the Event Stream of all connected nodes, acting as a passthrough and replicating the SSE interface of the connected nodes and their filters (i.e., `/main`, `/deploys`, and `/sigs` with support for the use of the `?start_from=` query to allow clients to get previously sent events from the Sidecar's buffer). - -* Provide a new RESTful endpoint that is discoverable to node operators. See the [usage instructions](USAGE.md) for details. - -The SSE Sidecar uses one ring buffer for outbound events, providing some robustness against unintended subscriber disconnects. If a disconnected subscriber re-subscribes before the buffer moves past their last received event, there will be no gap in the event history if they use the `start_from` URL query. +Casper Sidecar has three main functionalities: +* Providing a SSE server with a firehose `/events` endpoint that streams all events from the connected nodes. Sidecar also stores observed events in storage. +* Providing a REST API server that allows clients to query events in storage. +* Be a JSON RPC bridge between end users and a Casper node's binary RPC port. + +The system has the following components and external dependencies: +```mermaid + graph LR; + subgraph CASPER-SIDECAR + SSE_SERVER["SSE server"] + RPC_API_SERVER["RPC API server (json)"] + REST_API["Rest API server"] + ADMIN_API["Admin API server"] + end + CONFIG{{"Config file (toml)"}} + CONFIG --> CASPER-SIDECAR + STORAGE[(Storage)] + NODE_SSE(("Casper Node SSE port")) + NODE_BINARY(("Casper Node binary port")) + RPC_API_SERVER --> NODE_BINARY + SSE_SERVER --> NODE_SSE + SSE_SERVER --> STORAGE + STORAGE --> REST_API +``` + +#### SSE Server + +Diving into the SSE Server, we see the following components: +```mermaid + graph TD; + CLIENT{Client} + CLIENT --> SSE_SERVER_API + STORAGE[("Storage")] + CONFIG{{"Config file (toml)"}} + MAIN --1.reads--> CONFIG + NODE_SSE{Node SSE port} + SSE_LISTENER --2--> STORAGE + NODE_SSE --1--> SSE_LISTENER + subgraph "Casper sidecar" + MAIN[main.rs] + MAIN --2.spawns---> SSE-SERVER + subgraph SSE-SERVER + SSE_SERVER_API["SSE API"] + RING_BUFFER["Events buffer"] + SSE_SERVER_API --> RING_BUFFER + SSE_LISTENER --3--> RING_BUFFER + subgraph "For connection in connections" + SSE_LISTENER["SSE Listener"] + end + end + end +``` + +Given the flow above, the SSE Listener processes events in this order: +1.

The RPC protocol allows for basic operations like querying global state, sending transactions and deploys, etc. All of the RPC methods are documented [here](https://docs.casper.network/developers/json-rpc/). ## Protocol The sidecar maintains a TCP connection with the node and communicates using a custom binary protocol built on top of [Juliet](https://github.com/casper-network/juliet). The protocol uses a request-response model where the sidecar sends simple self-contained requests and the node responds to them.

The SSE Sidecar uses this API to achieve the following goals: - -* Build a sidecar middleware service that reads the Event Stream of all connected nodes, acting as a passthrough and replicating the SSE interface of the connected nodes and their filters (i.e., `/main`, `/deploys`, and `/sigs` with support for the use of the `?start_from=` query to allow clients to get previously sent events from the Sidecar's buffer). - -* Provide a new RESTful endpoint that is discoverable to node operators. - -The SSE Sidecar uses one ring buffer for outbound events, providing some robustness against unintended subscriber disconnects. If a disconnected subscriber re-subscribes before the buffer moves past their last received event, there will be no gap in the event history if they use the `start_from` URL query. - - -## Configuration +## Sidecar Configuration on the Node The file `/etc/casper-sidecar/config.toml` holds a default configuration.

From now the [sse_server] config section has a disable_event_persistence property. If set to true, Sidecar will not store events to database. [storage.sqlite_config] and [storage.postgresql_config] are optional. Also [storage.sqlite_config] and [storage.postgresql_config] have enabled property. If set to false, Sidecar will treat them as if they are not defined at all.

It allows subscribers to monitor a node's event stream, query stored events, and query the node's JSON RPC API, thus receiving faster responses and reducing the load placed on the node. Its primary purpose is to: -* Offload the node from broadcasting SSE events to multiple clients. -* Provide client features that aren't part of the nodes' functionality, nor should they be. +- Offload the node from broadcasting SSE events to multiple clients. +- Provide client features that aren't part of the nodes' functionality, nor should they be. While the primary use case for the Sidecar application is running alongside the node on the same machine, it can be run remotely if necessary. ## System Components and Architecture The Casper Sidecar provides the following functionalities: -* A server-sent events (SSE) server with an `/events` endpoint that streams all the events received from all connected nodes. The Sidecar also stores these events. -* A REST API server that allows clients to query stored events. -* A JSON RPC bridge between end users and a Casper node's binary port. -* Legacy emulation for clients using older versions of the SSE API. + +- A server-sent events (SSE) server with an `/events` endpoint that streams all the events received from all connected nodes.
