2. Tests failed: reason and relevant logs

2.1 python-v0.x x rust-v0.56 (tcp, noise, yamux)

Reason: Rust listener closes the connection with KeepAliveTimeout during the first upload. Python dialer then hits Stream is closed / StreamReset while sending.

Relevant log excerpts:

python-v0_x_x_rust-v0_56__tcp__noise__yamux__listener  | Connection closed with 12D3KooW...: Some(KeepAliveTimeout)

---

2.2 python-v0.x x rust-v0.56 (tcp, noise, mplex)

Reason: All 10 upload iterations complete; then Rust listener closes with KeepAliveTimeout before the download phase. Python dialer then fails the first download with Expected to receive 1073741824 bytes, but received 0.

Relevant log excerpts:

python-v0_x_x_rust-v0_56__tcp__noise__mplex__dialer    | Upload iteration 10/10: 9.05 Gbps
python-v0_x_x_rust-v0_56__tcp__noise__mplex__listener  | Connection closed with 12D3KooW...: Some(KeepAliveTimeout)

...
python-v0_x_x_rust-v0_56__tcp__noise__mplex__dialer    |     | ValueError: Expected to receive 1073741824 bytes, but received 0

---

2.3 python-v0.x x rust-v0.56 (tcp, tls, yamux)

Reason: Same as 2.1 — Rust KeepAliveTimeout, then Python Stream is closed / StreamReset during upload.

Relevant log excerpts:

python-v0_x_x_rust-v0_56__tcp__tls__yamux__listener  | Connection closed with 12D3KooW...: Some(KeepAliveTimeout)
python-v0_x_x_rust-v0_56__tcp__tls__yamux__dialer    | Error sending 262000/1073741824 bytes to 12D3KooW...:

---

2.4 python-v0.x x rust-v0.56 (ws, noise, yamux)

Reason: Same as 2.1 — Rust KeepAliveTimeout, then Python Stream is closed / StreamReset during upload.

Relevant log excerpts:

python-v0_x_x_rust-v0_56__ws__noise__yamux__listener  | Connection closed with 12D3KooW...: Some(KeepAliveTimeout)
python-v0_x_x_rust-v0_56__ws__noise__yamux__dialer    | Error sending 262000/1073741824 bytes to 12D3KooW...:

---

2.5 python-v0.x x rust-v0.56 (ws, noise, mplex)

Reason: Same pattern as 2.2 — uploads complete, Rust closes with KeepAliveTimeout, then Python fails download with Expected to receive 1073741824 bytes, but received 0.

Relevant log excerpts:

python-v0_x_x_rust-v0_56__ws__noise__mplex__listener  | Connection closed with 12D3KooW...: Some(KeepAliveTimeout)
python-v0_x_x_rust-v0_56__ws__noise__mplex__dialer    | Error sending 0/0 bytes to 12D3KooW...: Expected to receive 1073741824 bytes, but received 0
...
python-v0_x_x_rust-v0_56__ws__noise__mplex__dialer    |     | ValueError: Expected to receive 1073741824 bytes, but received 0

---

2.6 python-v0.x x rust-v0.56 (ws, tls, yamux)

Reason: Same as 2.1 — Rust KeepAliveTimeout, then Python Stream is closed / StreamReset during upload.

Relevant log excerpts:

python-v0_x_x_rust-v0_56__ws__tls__yamux__listener  | Connection closed with 12D3KooW...: Some(KeepAliveTimeout)
python-v0_x_x_rust-v0_56__ws__tls__yamux__dialer    | Error sending 262000/1073741824 bytes to 12D3KooW...:

python-v0_x_x_rust-v0_56__ws__tls__yamux__dialer    |     | libp2p.network.stream.exceptions.StreamReset

---

2.7 python-v0.x x rust-v0.56 (quic-v1)

Reason: Python dialer opens a stream but Rust does not support the protocol Python uses for the initial handshake: protocol not supported: /ipfs/id/1.0.0, response='na'. The stream is then reset; Python later gets cannot call write() after reset() during upload.

Relevant log excerpts:

python-v0_x_x_rust-v0_56__quic-v1__dialer    | Failed to open stream to peer 12D3KooWCpCxeT1MCET8yQVSQKVCV7HBFmR32zkJs9rk8vhyA43a:

---

2.8 python-v0.x x python-v0.x (tcp, noise, yamux)

Reason: Test timed out after 300s. Python yamux throughput is low (~0.19 Gbps); 20 × 1 GB iterations exceed the runner timeout.

Relevant log excerpts:

[2026-02-01 04:25:08] ERROR:   ✗ Test timed out after 300s
[2026-02-01 04:25:08] ERROR: Test timed out after 300 seconds

---

2.9 python-v0.x x python-v0.x (tcp, tls, yamux)

Reason: Same as 2.8 — Test timed out after 300s (Python yamux slow, 20 × 1 GB exceeds 300s).

Relevant log excerpts:

[2026-02-01 04:30:58] ERROR:   ✗ Test timed out after 300s
[2026-02-01 04:30:58] ERROR: Test timed out after 300 seconds

---

2.10 python-v0.x x python-v0.x (ws, noise, yamux)

Reason: Same as 2.8 — Test timed out after 300s.

Relevant log excerpts:

[2026-02-01 04:37:33] ERROR:   ✗ Test timed out after 300s
[2026-02-01 04:37:33] ERROR: Test timed out after 300 seconds

---

2.11 python-v0.x x python-v0.x (ws, tls, yamux)

Reason: Same as 2.8 — Test timed out after 300s.

Relevant log excerpts:

[2026-02-01 04:44:31] ERROR:   ✗ Test timed out after 300s
[2026-02-01 04:44:31] ERROR: Test timed out after 300 seconds

---

2.12 python-v0.x x python-v0.x (quic-v1)

Reason: Listener (py-libp2p) cannot send on the peer-initiated stream: Cannot send data on unknown peer-initiated stream. Upload phase completes (10/10); first download fails because the listener never sent the response, so the dialer gets Expected to receive 1073741824 bytes, but received 0.

Relevant log excerpts:

python-v0_x_x_python-v0_x__quic-v1__listener  | Error writing to stream 4: Cannot send data on unknown peer-initiated stream
python-v0_x_x_python-v0_x__quic-v1__listener  | Stream 4 error: Cannot send data on unknown peer-initiated stream
python-v0_x_x_python-v0_x__quic-v1__dialer    | Upload iteration 1/10: 2.50 Gbps
...
python-v0_x_x_python-v0_x__quic-v1__dialer    | Error sending 0/0 bytes to 12D3KooW...: Expected to receive 1073741824 bytes, but received 0
...
