== iperf 3.?.? ????-??-?? ==
|
|
|
|
* User-visible changes
|
|
|
|
* The iperf3 project has been moved to GitHub, and various URLs in
|
|
documentation files have been changed to point there.
|
|
|
|
* Setting CPU affinity now works on FreeBSD.
|
|
|
|
* iperf3 now builds on Linux systems that do not support
|
|
TCP_CONGESTION. Most notably this allows iperf3 to work on CentOS
|
|
5.
|
|
|
|
* Selection of TCP congestion now works on FreeBSD, and is now
|
|
called --congestion (the old --linux-congestion option works
|
|
but is now deprecated).
|
|
|
|
* An abort on MacOS 10.9 has been fixed (issue #135).
|
|
|
|
* Added -I flag for the server to write a PID file, mostly useful for
|
|
daemon mode (issue #120).
|
|
|
|
* A bug that could break some TCP tests on FreeBSD has been fixed.
|
|
|
|
* TCP snd_cwnd output is now printed by default on Linux (issue #99).
|
|
|
|
* SCTP support has been added (with the --sctp flag), on Linux and
|
|
FreeBSD (issue #131).
|
|
|
|
* In JSON output, the --title string no longer has a colon and two
|
|
spaces appended (issue #139).
|
|
|
|
* A buffer for holding formatted numeric values is now
|
|
properly-sized so that output is not truncated (issue #142).
|
|
|
|
* A --logfile argument can now force all output to go to a file,
|
|
rather than to a file. This is especially useful when running an
|
|
iperf3 server in daemon mode (issue #119).
|
|
|
|
* Summary structures in the JSON output are now included, even if
|
|
there is only one stream. This change makes consuming the JSON
|
|
output easier and more consistent (issue #151).
|
|
|
|
* A possible buffer overflow in iperf_error.c has been fixed (issue
|
|
#155).
|
|
|
|
* A timing issue which caused measurement intervals to be wrong
|
|
with TCP tests on lossy networks has been fixed (issue #125).
|
|
|
|
* Newer versions of autoconf / automake / libtool are now used by
|
|
default (issue #161).
|
|
|
|
* The maximum test running time is now one day, up from one hour
|
|
(issue #166).
|
|
|
|
* JSON output now indicates whether the test was run in --reverse
|
|
mode (issue #167).
|
|
|
|
* It is now possible to get (most of) the server-side output at
|
|
the client by using the --get-server-output flag (issue #160).
|
|
|
|
* Various problems with the -B option have been fixed (issue #193).
|
|
|
|
* Various compatibility fixes for Android (issue #184, issue #185),
|
|
OpenBSD (issue #196), Solaris (#177, issue #180).
|
|
|
|
* A server bug where new connections from clients could disrupt
|
|
running tests has been fixed (issue #202).
|
|
|
|
* Rates now consistently use 1000-based prefixes (K, M, G), where
|
|
sizes of objects now consistently use 1024-based prefixes (issue #173).
|
|
|
|
* UDP tests with unlimited bandwidth are now supported (issue #170).
|
|
|
|
* Developer-visible changes
|
|
|
|
* Some memory leaks have been fixed.
|
|
|
|
* A -d flag enables debugging output.
|
|
|
|
* A .gitignore file has been added.
|
|
|
|
* libtoolize is now invoked correctly from the bootstrap.sh script.
|
|
|
|
* The test unit format can now be set from the API (issue #144).
|
|
|
|
* libiperf is now built by default as both shared and static
|
|
libraries (issue #146, issue #152).
|
|
|
|
* Consumers of libiperf can now get the JSON output for a
|
|
just-completed test (issue #147).
|
|
|
|
* Detection of various optional features has been improved to check
|
|
for the presence or absence of platform functionality, not the name
|
|
of platforms.
|
|
|
|
* In the JSON output, the "connection" structures are now stored as
|
|
an array in the "start" block, instead of overwriting each other.
|
|
While technically an incompatible API change, the former behavior
|
|
generated unusable JSON.
|
|
|
