Wed Mar 11 10:40:53 UTC 2026 - Martin Hauke <mardnh@gmx.de>
- Update to version 0.9.3:
* Fix server random payload on single-port TCP reverse (#34).
* Fix QUIC dual-stack, add server --bind, server random payloads.
-------------------------------------------------------------------
Sat Mar 7 09:48:56 UTC 2026 - Martin Hauke <mardnh@gmx.de>
- Update to version 0.9.2:
Changed
* Random payloads by default (issue #34) — TCP/UDP client-sent
payloads now use random bytes by default to avoid silently
inflated results on WAN-optimized or compressing paths.
--random remains as an explicit no-op for clarity, and new
--zeros forces zero-filled payloads for compression/dedup
testing. Reverse mode sender remains server-side zeros until
protocol negotiation is added.
Fixed
* MPTCP namespace test realism (issue #32) — test-mptcp-ns.sh now
combines netem shaping with fq_codel on the shaped transit
links, matching common Linux defaults more closely and reducing
false-positive high-stream failures caused by shallow unfair
queues in the test harness.
-------------------------------------------------------------------
Fri Mar 6 20:12:50 UTC 2026 - Martin Hauke <mardnh@gmx.de>
- Update to version 0.9.1:
Added
* MPTCP support (--mptcp) — Multi-Path TCP on Linux 5.6+
* Kernel TCP pacing via SO_MAX_PACING_RATE
Changed
* Library API — create_tcp_listener(), connect_tcp(),
and connect_tcp_with_bind() now take a mptcp: bool parameter.
Pass false to preserve existing behavior.
Fixed
* High stream-count teardown hardening (issue #32) — client now
stops local data streams at local duration expiry instead of
waiting for server Result, scales stream join timeout with
stream count (max(2s, streams*50ms)), and TCP receivers drain
briefly after cancel to reduce reset-on-close bursts at
high -P.
* Best-effort send shutdown — send_data() shutdown no longer
propagates errors during normal teardown races.
* Kernel pacing rate width — SO_MAX_PACING_RATE now uses
native c_ulong instead of u32, removing an unintended ~34 Gbps
ceiling on 64-bit Linux.
* JoinHandle panic with many parallel streams (issue #24).
* Final summary showing 0 retransmits/RTT/cwnd (issue #26).
* Broken pipe / connection reset at teardown (issue #25).
* MPTCP label in server log — server displays "MPTCP" instead of
"TCP" when client uses --mptcp.
-------------------------------------------------------------------
Fri Feb 13 08:20:00 UTC 2026 - Martin Hauke <mardnh@gmx.de>
- Update to version 0.8.0:
* Add QUIC --cport dual-stack IPv6 integration test.
* Validate UDP data_ports length before spawning streams.
* Add --cport flag for client source port pinning (issue #16).
-------------------------------------------------------------------
Thu Feb 12 19:39:58 UTC 2026 - Martin Hauke <mardnh@gmx.de>
- Update to version 0.7.1
Fixed
* Server TUI '-0.0 Mbps' after test ends: (issue #20) - IEEE 754
negative zero now normalized via precision-aware
'normalize_for_display()' helper across all throughput display
paths.
* TCP RTT/retransmits not updating live (issue #13) -
per-interval retransmits now computed from TCP_INFO deltas
instead of a dead atomic counter; client stores socket fds for
local TCP_INFO polling so sender-side metrics (upload/bidir)
update live; download mode correctly uses server-reported
metrics
* Plain-text zero retransmits dropped - 'rtx: 0' was omitted in
plain/JSON/CSV interval output when all streams reported zero
retransmits; now preserved
* 'mbps_to_human()' unit-switch boundary - '999.95 Mbps'
displayed as '1000.0 Mbps' instead of '1.00 Gbps'; unit branch
now uses rounded value
Changed
* Consolidated throughput formatting - server TUI now uses shared
'mbps_to_human()' instead of inline formatting; Gbps display
hanges from 1 to 2 decimal places for consistency.
