FrozenStorage - content-addressable storage +10. Root-Level Concurrent Modifications - different nodes modifying different root fields simultaneously + +## Architecture + +The app state (`ComprehensiveCrdtApp`) contains all CRDT types and storage types as root-level fields. This design allows testing root-level concurrent modifications where: +- Node 1 modifies `root_counter` +- Node 2 modifies `root_map` +- Node 1 modifies `root_set` + +All concurrently, triggering `merge_root_state` to merge all fields correctly. diff --git a/apps/comprehensive-crdt-test/build.rs b/apps/comprehensive-crdt-test/build.rs new file mode 100644 index 000000000..070defd55 --- /dev/null +++ b/apps/comprehensive-crdt-test/build.rs @@ -0,0 +1,38 @@ +use std::fs; +use std::path::Path; + +use calimero_wasm_abi::emitter::emit_manifest; + +fn main() { + println!("cargo:rerun-if-changed=src/lib.rs"); + + // Parse the source code + let src_path = Path::new("src/lib.rs"); + let src_content = fs::read_to_string(src_path).expect("Failed to read src/lib.rs"); + + // Generate ABI manifest using the emitter + let manifest = emit_manifest(&src_content).expect("Failed to emit ABI manifest"); + + // Serialize the manifest to JSON + let json = serde_json::to_string_pretty(&manifest).expect("Failed to serialize manifest"); + + // Write the ABI JSON to the res directory + let res_dir = Path::new("res"); + if !res_dir.exists() { + fs::create_dir_all(res_dir).expect("Failed to create res directory"); + } + + let abi_path = res_dir.join("abi.json"); + fs::write(&abi_path, json).expect("Failed to write ABI JSON"); + + // Extract and write the state schema + if let Ok(mut state_schema) = manifest.extract_state_schema() { + state_schema.schema_version = "wasm-abi/1".to_owned(); + + let state_schema_json = + serde_json::to_string_pretty(&state_schema).expect("Failed to serialize state schema"); + let state_schema_path = res_dir.join("state-schema.json"); + fs::write(&state_schema_path, state_schema_json) + .expect("Failed to write state schema JSON"); + } +} diff --git a/apps/comprehensive-crdt-test/build.sh b/apps/comprehensive-crdt-test/build.sh new file mode 100755 index 000000000..e64365291 --- /dev/null +++ b/apps/comprehensive-crdt-test/build.sh @@ -0,0 +1,19 @@ +#!/bin/bash +set -e + +# Add wasm32 target if not already present +rustup target add wasm32-unknown-unknown || true + +# Build the app +cargo build -p comprehensive-crdt-test --target wasm32-unknown-unknown --release + +# Copy WASM file to res directory +mkdir -p res +cp target/wasm32-unknown-unknown/release/comprehensive_crdt_test.wasm res/comprehensive_crdt_test.wasm + +# Optimize WASM if wasm-opt is available +if command -v wasm-opt &> /dev/null; then + wasm-opt -O2 res/comprehensive_crdt_test.wasm -o res/comprehensive_crdt_test.wasm || true +fi + +echo "Build complete: res/comprehensive_crdt_test.wasm" diff --git a/apps/comprehensive-crdt-test/src/lib.rs b/apps/comprehensive-crdt-test/src/lib.rs new file mode 100644 index 000000000..d390e5c0e --- /dev/null +++ b/apps/comprehensive-crdt-test/src/lib.rs @@ -0,0 +1,419 @@ +//!
