Flent v0.14.0.
This release adds mixins for capturing qdisc stats and CPU usage, adds some convenience functions to the GUI and fixes a bunch of bugs, most notably making the GUI work on Windows.
- Batch mode: Try to estimate the total runtime of a batch and print it before executing the batch itself.
- GUI: Add support for pinning a metadata item open when flipping between tabs, and support adding columns to the open files view from the metadata view. Both functions are available from the context menu when right-clicking in the metadata view.
- Add test mixins to a bunch of tests making it possible to simultaneously capture qdisc stats and/or CPU stats of one or more hosts while the test is run. This works by setting the test parameters qdisc_stats_hosts, qdisc_stats_interfaces and cpu_stats_hosts to comma-separated lists of hosts and interface names. The functionality relies on the tc_iterator and stats_iterator helper scripts.
- Add a C implementation of the tc_iterator helper script that works on OpenWrt and also gives higher polling accuracy than the shell script.
- Add a kill_timeout setting for runners in test definitions which will forcibly kill a subprocess after an interval (if it hasn't exited already).
- Add the tcp_upload_1000 test for seriously overloading things. On most systems, increasing the ulimit is necessary to run this test.
- Support globbing selectors in plot configuration when specifying datasets for a plot.
- Record number of failed runners (non-0 exit status) as a metadata key.
- GUI: Fix bugs in plot blitting on older matplotlibs, fix test running without a pre-set HOST, fix bugs in draw cache handling, and restore the GUI to a working state on Windows.
- Various bugfixes.
