Fix super() typo
Clean up - TCReapply still broken!
Remove shared reconnectms, improve self.started
We still need to set it in batchShutdown()
Refactor for compatibility with isOldOVS() == True
First crack at setting controller backoff in single command
Add OVSBatch class (experimental)
This implements batch startup for OVS switches.
Return correct success condition in cgroupDel
Without this, we end up retrying until we fail, insteadof returning immediately on success!
Call delete() in link.stop() ; warn on exited node.cmd()
We should think a bit about the semantics that we want here.The comments say "stop and clean up link" so perhaps that'swhat we want. However, we could also imagine stop stoppingforwarding on the link (and possibly allowing restarts)....
Pass code check
Add stp param to OVS and connected() to OVSBridge
This allows --switch ovsbr,stp=True to work correctly
Merge del-br into cmd, and add reconnectms param
With newer versions of OVS, this allows us to set up a switchwith a single OVS command (if reconnectms is zero.) If reconnectmsis specified, then it slows things down slightly (but not much.)
Stub out RemoteOVSSwitch.batchShutdown()
Eventually we should implement true batch shutdown.In the mean time, we just ignore it. Note there's no goodway that I know of for a subclass to remove a superclassmethod, so we changed the protocol a bit to require a return...
use isinstance( intf, OVSIntf )
Add OVSLink/--link ovs, which uses OVS patch links when possible
Revert to using OVS default OpenFlow versions.
It makes sense to follow Open vSwitch's lead here.OVS 2.3 enables OpenFlow 1.0 through 1.3 by default.OVS 2.0 has incomplete support for 1.3, but you can enableit with protocols=OpenFlow13
Set OVSSwitch default protocols to OpenFlow10,OpenFlow13
For OVS versions 1.9 or earlier, this setting is ignored.
Fix code minor code check errors
Correctly set controller backoff for OVS.
Also report connected in standalone/bridge mode
Spacing tweaks for pep8 checker
Restore missing space in RT_GROUP_SCHED message
warn -> debug in connected; change IVS class comment
Maybe this is better - maybe not. ;-p
More pylint changes
Fixing pylint errors
Remove trailing whitespace. ;-/
Set default route in one cmd line to avoid dc'ing root NS
Usually you won't want to create a node in the root namespace,and usually you won't want to use the Mininet API to set your(real) default route, but if you do then you will probably wantto use a single command line to avoid disconnecting an SSH...
Merge pull request #450 from mininet/sw-cmd
adding deleteIntfs option to switches and corresponding CLI command
Remove unused imports
Fix typo. ;-p
type( foo ) is bar -> isinstance( foo, bar )
use isinstance( obj, basestring) to allow unicode strings
IVSSwitch: turn off verbose logging by default
Most users don't need this much logging and it slows down the switch.
Don't blow away parameters that aren't specified in node.config()
Merge pull request #432 from mininet/devel/fallback
Fall back to OVSBridge if no controller is available for default switch
Raise exception if DefaultController cannot find a controller
Return controller correctly.
Don't check rt_runtime_us for CFS scheduler
Reorganize CFS and RT default/error conditions.
Move RT check into its own method, and save value.
Merge pull request #419 from cdburkard/patches/rt_failure_output
fix silent failures when rt cannot be assigned - will follow up on this
Merge branch 'fallback' of https://github.com/thinred/mininet into thinred-fallback
Conflicts: bin/mn mininet/node.py
Update module comment.
fix silent failures when rt cannot be assigned
unmount private directories after use
merge HostWithPrivateDirs into Host
Wait for controller shutdown.
Unfortunately, this can slow things down a bit - perhaps100-200 ms in the case of ovs-controller, but I am hoping thatit may help slightly with #399.
Merge pull request #391 from cdburkard/patches/fix_popen
workaround: attach to cgroup first, then mount namespace
add Ryu controller to mininet

Merge pull request #374 from cdburkard/patches/rt
check if RT_GROUP_SCHED is enabled in kernel
Cluster edition prototype: remote nodes and links.
We add a new experimental feature to allow Mininet to run acrossa cluster of machines. This is currently implemented via a setmix-in classes that provide remote nodes that are implementedvia a connection to a remote shell, and remote links which are...
wall clock time makes rt quota independent of nprocs

improve startup performance, largely by removing unnecessary ifconfigs
Merge pull request #353 from mininet/devel/nat
Adding NAT class to NodeLib
Merge pull request #356 from cdburkard/patches/stop_controller
fix for controller shutdown - send SIGHUP rather than SIGKILL
added controller.stop() back in
kill all child processes to avoid race condition and no controller shutdown

Conflicts: mininet/net.py mininet/node.py
removed more unnecessary ifconfigs
switched back to node.cmd for OVS commands. this is faster..
added some documentation
fixed issue with regex matching
adding old changes
few small fixes to syntax errors
removed many of the commands being run to maximize startup performance
Reverting the disable signals change
Merge branch 'master' into devel/pty
Add parameter to set protocol list in OVSSwitch. Allows setting OpenFlow version. s2 = net.addSwitch( 's2', protocols='OpenFlow13' )

restructured defaultController into a function
fixed command parameter
added default controller class

conforming to mininet style
Possibly faster check for sentinel.
Don't set self.waiting twice
Avoid overhead of another process (env) in startShell()
Attach a pty to each node's bash process
This should enable node commands that are expecting a tty tobehave better.
Whitespace changes in OVSSwitch.
