Some checks failed
Build Release Binaries / build-amd64 (push) Failing after 3m53s
Last bisection step. cpp/cpp_smoke.cpp reduced to a single extern 'C'
function that returns 42. No #include, no std::atomic, no std::mutex,
no std::thread. Only C++ things remaining are:
- cc::Build::new().cpp(true) in build.rs (C++ mode compile)
- cpp_link_stdlib('c++_shared') emitting -lc++_shared
If this still crashes with the same __init_tcb+4 / pthread_create
stack, we've conclusively proven the trigger is NOT any C++ code
that ends up in the final .so (everything gets dead-stripped
anyway because Rust never references wzp_cpp_hello). The trigger
must be either:
a) cargo:rustc-link-lib=c++_shared (adds NEEDED entry for
libc++_shared.so in the .so's dynamic table, causing the
dynamic linker to load libc++_shared.so at dlopen() time
alongside our .so), or
b) Some interaction between cpp(true) mode and the rest of the
build pipeline (toolchain flags, symbol visibility, etc.)
After this build we stop and write an incident report for the
WarzonePhone Tauri Android rewrite bisection so far.

WarzonePhone
Custom lossy VoIP protocol built in Rust. E2E encrypted, FEC-protected, adaptive quality, designed for hostile network conditions.
Quick Start
# Build
cargo build --release
# Run relay
./target/release/wzp-relay --listen 0.0.0.0:4433
# Send a test tone
./target/release/wzp-client --send-tone 5 relay-addr:4433
# Web bridge (browser calls)
./target/release/wzp-web --port 8080 --relay 127.0.0.1:4433 --tls
# Open https://localhost:8080/room-name in two browser tabs
Architecture
See docs/ARCHITECTURE.md for the full system architecture with Mermaid diagrams covering:
- System overview and data flow
- Crate dependency graph (8 crates)
- Wire formats (MediaHeader, MiniHeader, TrunkFrame, SignalMessage)
- Cryptographic handshake (X25519 + Ed25519 + ChaCha20-Poly1305)
- Identity model (BIP39 seed, featherChat compatible)
- Quality profiles (GOOD/DEGRADED/CATASTROPHIC)
- FEC protection (RaptorQ with interleaving)
- Adaptive jitter buffer (NetEq-inspired)
- Telemetry stack (Prometheus + Grafana)
- Deployment topology
Features
- 3 quality tiers: Opus 24k (28.8 kbps) / Opus 6k (9 kbps) / Codec2 1200 (2.4 kbps)
- RaptorQ FEC: Recovers from 20-100% packet loss depending on tier
- E2E encryption: ChaCha20-Poly1305 with X25519 key exchange
- Adaptive jitter buffer: EMA-based playout delay tracking
- Silence suppression: VAD + comfort noise (~50% bandwidth savings)
- ML noise removal: RNNoise (nnnoiseless pure Rust port)
- Mini-frames: 67% header compression for steady-state packets
- Trunking: Multiplex sessions into batched datagrams
- featherChat integration: Shared BIP39 identity, token auth, call signaling
- Prometheus metrics: Relay, web bridge, inter-relay probes
- Grafana dashboard: Pre-built JSON with 18 panels
