All notable changes to this project will be documented in this file.
The format is based on Keep a Changelog and this project adheres to Semantic Versioning.
- Added --ecn server option to ship ECN bits (currently IPv6 only)
- Add oneway test packets from client to server (needs external clock sync
between client and server machines,
--tripm
flag) - At the server the output file could be saved
- Improve Windows time support by using
QueryPerformanceCounter
andGetSystemTimePreciseAsFileTime
. Time precision on Windows 10 can now reach 100ns. - Add syslog support for the server (
--syslog
flag). - Add a SmokePing probe, available from SmokePing 2.7.2. It's possible to copy the code into older versions.
- Update OM2P build to use the new MIPS softfloat support in Go 1.10.
- Re-write git history with new email address.
- Re-licensed to GPLv2.
- Stop disabling GC on client and remove
--gc
flag from server as disabling GC no longer offers a demonstrable performance benefit. See The Journey of Go's Garbage Collector.
- Fix potential client race at startup.
- Fix issue on platforms with timer resolution not accurate enough to measure server processing time (closes #13).
- Change handled interrupt signals to only
os.Interrupt
andsyscall.SIGTERM
to fix Plan 9 build. - Various documentation fixes.
- Server fills are now supported, and may be restricted on the server. See
--sfill
for the client and--allow-fills
on the server. As an example, one can doirtt client --fill=rand --sfill=rand -l 172 server
for random payloads in both directions. The server default is--allow-fills=rand
so that arbitrary data cannot be relayed between two hosts.server_fill
now appears underparams
in the JSON. - Version information has been added to the JSON output.
- Due to adoption of the pflag package, all long
options now start with -- and must use = with values (e.g.
--fill=rand
). After the subcommand, flags and arguments may now appear in any order. irtt client
syntax changes:-rs
is renamed to--stats
-strictparams
is removed and is now the default.--loose
may be used instead to accept and use server restricted parameters, with a warning.-ts
is renamed to--tstamp
-qq
is renamed to-Q
-fillall
is removed and is now the default.--fill-one
may be used as a small optimization, but should rarely be needed.
irtt server
syntax changes:-nodscp
is renamed to--no-dscp
-setsrcip
is renamed to--set-src-ip
- The communication protocol has changed, so clients and servers must both be updated.
- The handshake now includes a protocol version, which may change independently of the release version, and must match exactly between the client and server or the client will refuse to connect.
- The default server minimum interval is now
10ms
. - The default client duration has been changed from
1h
to1m
. - Some author info was changed in the commit history, so the rewritten history must be fetched in all forks and any changes rebased.
- Initial, untagged development release.
