Including changes to mnexec -c to reduce the number of
close() system calls, which may help with performance in
containers on Ubuntu 22.04.
Note that systemd-udevd also seems to be a cause of performance issues
and should probably be disabled while running Mininet.
Adding dbeug logging to test_simpleperf because it is failing
intermittently. (Note with packet loss it can fail, but this
is not how we should be testing it.)
Support for Ubuntu 22.04 and 20.04.
- Update Mininet version
- Install pexpect with pip to support python 3 and 2
- Update code-check workflow
- refactor to enable testing python 2 on ubuntu 22.04
- update to actions/checkout@v3 (@v2 is deprecated)
errata:
mountCgroups has not actually been renamed, but has been
changed to use cgroupfs-mount and to return the cgroups version.
Ubuntu 20.04 fixes:
- fixes sshd test
- speeds up examples/{treeping64,tree1024}.py
- debugging hacks/output for testLinkChange
- removes cfs from examples/popen.py
- improves nat in nodelib (netplan fixes?)
- makes some tests executable
- waits for switches to connect in tests to
avoid race conditions
-- adds mn -w option and wait CLI command
Changes:
- REMOVES default "-v" argument for Controller()
and adds verbose(=False) option; avoiding logging
makes it faster
- CHANGES waitConnected to wait for 5 seconds
as documented; we may wish to implement an argument
to -w to set this timeout
Issues?
- There may still be an issue with the ovs-netplan-clean
service causing the boot to hang ;-(
