From 76e299fd433db7d32532faa03d7bf7a1d0477d2a Mon Sep 17 00:00:00 2001 From: quantumshiro Date: Mon, 16 Jun 2025 04:06:45 +0900 Subject: [PATCH 1/5] feat: Add Transaction Monitor and Multi-Node Simulation Scripts - Implemented a Transaction Monitor in Rust to observe transaction flow between nodes. - Created a multi-node simulation script to manage multiple node instances for testing. - Developed a simulation manager script for easy command execution of various simulation scenarios. - Added a simulation API for handling transaction requests and node status checks. - Enhanced logging and output for better monitoring and debugging during simulations. --- Cargo.lock | 55 ++++ Cargo.toml | 9 + config/docker-node.toml | 57 ++++ docker-compose.yml | 184 ++++++++++++ docs/MULTI_NODE_SIMULATION.md | 216 ++++++++++++++ examples/multi_node_simulation.rs | 454 ++++++++++++++++++++++++++++++ examples/transaction_monitor.rs | 266 +++++++++++++++++ scripts/multi_node_simulation.sh | 249 ++++++++++++++++ scripts/simulate.sh | 382 +++++++++++++++++++++++++ src/command/cli.rs | 126 +++++++-- src/webserver/mod.rs | 2 + src/webserver/simulation_api.rs | 123 ++++++++ 12 files changed, 2106 insertions(+), 17 deletions(-) create mode 100644 config/docker-node.toml create mode 100644 docker-compose.yml create mode 100644 docs/MULTI_NODE_SIMULATION.md create mode 100644 examples/multi_node_simulation.rs create mode 100644 examples/transaction_monitor.rs create mode 100755 scripts/multi_node_simulation.sh create mode 100755 scripts/simulate.sh create mode 100644 src/webserver/simulation_api.rs diff --git a/Cargo.lock b/Cargo.lock index 6cee8f2..788c8b8 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -277,6 +277,21 @@ version = "0.2.21" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "683d7910e743518b0e34f1186f92494becacb047c7b6bf616c96772180fef923" +[[package]] +name = "android-tzdata" +version = "0.1.1" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "e999941b234f3131b00bc13c22d06e8c5ff726d1b6318ac7eb276997bbb4fef0" + +[[package]] +name = "android_system_properties" +version = "0.1.5" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "819e7219dbd41043ac279b19830f2efc897156490d7fd6ea916720117ee66311" +dependencies = [ + "libc", +] + [[package]] name = "anes" version = "0.1.6" @@ -751,6 +766,21 @@ dependencies = [ "zeroize", ] +[[package]] +name = "chrono" +version = "0.4.41" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "c469d952047f47f91b68d1cba3f10d63c11d73e4636f24f08daf0278abf01c4d" +dependencies = [ + "android-tzdata", + "iana-time-zone", + "js-sys", + "num-traits", + "serde", + "wasm-bindgen", + "windows-link", +] + [[package]] name = "ciborium" version = "0.2.2" @@ -2006,6 +2036,30 @@ dependencies = [ "windows-registry", ] +[[package]] +name = "iana-time-zone" +version = "0.1.63" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "b0c919e5debc312ad217002b8048a17b7d83f80703865bbfcfebb0458b0b27d8" +dependencies = [ + "android_system_properties", + "core-foundation-sys", + "iana-time-zone-haiku", + "js-sys", + "log", + "wasm-bindgen", + "windows-core", +] + +[[package]] +name = "iana-time-zone-haiku" +version = "0.1.2" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "f31827a206f56af32e590ba56d5d2d085f558508192593743f16b2306495269f" +dependencies = [ + "cc", +] + [[package]] name = "icu_collections" version = "2.0.0" @@ -2827,6 +2881,7 @@ dependencies = [ "bitvec", "blake3", "chacha20poly1305", + "chrono", "clap 2.34.0", "criterion", "dashmap", diff --git a/Cargo.toml b/Cargo.toml index 37d4528..e6de7c2 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -23,6 +23,14 @@ path = "examples/modular_architecture_simple.rs" name = "diamond_io_demo" path = "examples/diamond_io_demo.rs" +[[example]] +name = "multi_node_simulation" +path = "examples/multi_node_simulation.rs" + +[[example]] +name = "transaction_monitor" +path = "examples/transaction_monitor.rs" + [dependencies] # Cryptography -
