[PATCH] Python2 to Python3 conversion
by Jozef Urbanovsky 03 Sep '18

03 Sep '18

Main changes: ================================================ - Print function - PEP 3105[1] - Design of dictionaries, their iteration and respective built-in functions - PEP 469[2], PEP 3106[3] - Division operator - PEP 238[4] - Interrupts of system calls - PEP 475[5] - Socket.accept and interrupts - Docs Python3 Socket[6] - Universal newlines - PEP 278[7], PEP 3116[8], Docs Python3 Subprocess[9] - Binary data and strings - Docs Python3 porting[10] - Shebangs modified to environmental variable of python3 - Fixed library imports to reflect their respective changes in transition to python3 - multiprocessing - xmlrpc - urllib - thread - pickle InterfaceManager.py ================================================ - Byte string and unicode/ascii string conflict, fixed by mostly using a byte string through the project NetTestSlave.py ================================================ - signum 2 (SIGINT) - modified behavior since python 3.5 - Due to changes in interrupting system call, signal receiving and handling required changes to main slave loop - Structure of raising, catching and handling interrupt was changed, to reflect behavior of python 3.5 and higher - Method run is no longer ended by parameter "finished", but rather exception breaks the endless loop SecureSocket.py ================================================ - Byte string and unicode/ascii string conflict, fixed by using bytes internally and sending messages encoded to ascii - Fixed multiple issues regarding changes to standard python functions, such as encoding to hex, ordinal value of characters, length of different types NetTestCommand.py ================================================ - name_start_char is using unicode string, therefore each unicode has to be escaped twice ExecCmd.py ================================================ - Popen universal newlines - Abstraction to be able to read newlines regardless of system used and its basic encoding XmlParser.py ================================================ - etree.tostring function behavior changed to generate byte string by default - Unicode encoding is required, as specified by parameter NmConfigDevice.py ================================================ - Conversion of bytes array to integer value was changed, ord no longer returns plain integer value - Need to convert bytes array to integer - int.from_bytes - Reverse conversion does not need to account for bytes array, therefore it is redundant to convert IP twice ShellProcess.py ================================================ - Decoding file stream, to use unicode string instead of byte string, as built-in function read returns byte string by default in python3 Netperf.py ================================================ - Changed evaluation of results to account for changes made to base types in python3 - Dictionary comparision with integer by their respective lengths and values Machine.py ================================================ - List comprehension functionality in python3 was changed - New function to parse queried addresses from slaves - modified code from next branch - get_ip_addr returns a dictionary or IP address objects - fixed to return only IP address portion by getting addr attribute from dictionary ================================================ [1] -

[PATCH-next 00/40] porting of OvS DPDK PvP recipe
by olichtne＠redhat.com 23 Aug '18

23 Aug '18

From: Ondrej Lichtner <olichtne(a)redhat.com> What follows is a big patch set that is the result of my work to port the phase3/ovs_dpdk_pvp recipe to python. The recipe should be ported in almost complete support of everything that the old recipe did (except for result evaluation) and includes a significant refactoring of the code. Instead of working with a hackish ssh tunnel to manipulate the guest the patch set also introduces a new feature allowing the tester to connect to a LNST Slave during test execution. This significantly improves working with the guest since we can now safely wrap the testpmd process into a test module and have a comfortable interface for it. This removes the python paramiko library dependency of the recipe. Another significant improvement is a better way to wrap the TRex generator into test modules that avoids the use of a tmux session we've used previously this means that the recipe no longer has this dependency. Finally the patchset also includes a new feature of being able to synchronize and use arbitrary classes in the lnst.RecipeCommon package into any slave. This gives the tester a very nice interface to use for extending the slave functionality. In the OvS_DPDK_PvP recipe this is used to interface with libvirt on the slave machine. This means that the controller can now run on any machine and be able to work with libvirt on any other slave instead of the confusing forced binding we've had before. On top of these new features, the patch set also includes other smaller features, a lot of bug fixes and refactoring of some classes. -Ondrej Ondrej Lichtner (40): lnst.Common.DeviceError: define the DeviceReadOnly exception lnst.Devices.RemoteDevice: add caching capability lnst.Slave.NetTestSlave: refactor names of dev_*attr methods lnst.Device.Device: improve cleanup data storage lnst.Device.Device: raise DeviceDeleted exception on netlink updates lnst.Device.Device: add bus_info property lnst.Slave.Job: catch all exceptions from Test Modules lnst.Slave.Job: cleanup kill only running jobs move lnst.Common.TestModule to lnst.Tests.BaseTestModule, add wait_for_interrupt lnst.Common.Parameters: allow deletions for the Parameters class lnst.Controller.MachineMapper: sort interfaces in machine descriptions lnst.Controller.Machine: add mapped boolean lnst.Controller.MessageDispatcher: refactor wait_* methods lnst.Controller.Machine: expose init_connection as public method lnst.Controller.SlavePoolManager: enable machines without interfaces lnst.Controller.Machine: split set_recipe into prepare_machine and start_recipe lnst.Controller.Machine: move VirtualDevice cleanup to Controller lnst.Controller.Machine: refactor sending classes to Slaves lnst.Slave.NetTestSlave: track dynamic classes by module name as well lnst.Slave.NetTestSlave: create the dynamic RecipeCommon module lnst.Slave.NetTestSlave: support objects from dynamically received classes add lnst.Controller.SlaveObject add lnst.Controller.RecipeControl lnst.Controller.Host: expose the map_device api to the tester lnst.Controller.Requirements: add RecipeParam class lnst.Controller.RunSummaryFormatter: change format for list items lnst.Controller.Machine: small refactoring lnst.Slave.InterfaceManager: fix deleted device handling lnst.RecipeCommon.PerfResult: fix standard deviation calculation lnst.RecipeCommon.PerfResult: override std_deviation of PerfInterval and add string descrition lnst.RecipeCommon.Ping: add parameters to PingConf lnst.RecipeCommon.Perf: minor refactoring setup.py: use setuptools instead of distutils and improve package management add lnst.RecipeCommon.LibvirtControl add lnst.Tests.TRex add lnst.Tests.TestPMD add lnst.RecipeCommon.TRexMeasurementTool add lnst.Recipes.ENRT.OvS_DPDK_PvP lnst.Recipes.ENRT.BaseEnrtRecipe: fix indentation lnst.Slave.InterfaceManager: disable bulk mode after device creation lnst/Common/DeviceError.py | 3 + lnst/Common/Parameters.py | 3 + lnst/Controller/Controller.py | 41 +- lnst/Controller/Host.py | 8 +- lnst/Controller/Job.py | 2 +- lnst/Controller/Machine.py | 159 +++---- lnst/Controller/MachineMapper.py | 2 +- lnst/Controller/MessageDispatcher.py | 116 +++-- lnst/Controller/Recipe.py | 13 +- lnst/Controller/RecipeControl.py | 64 +++ lnst/Controller/Requirements.py | 47 ++- lnst/Controller/RunSummaryFormatter.py | 14 +- lnst/Controller/SlaveObject.py | 41 ++ lnst/Controller/SlavePoolManager.py | 7 +- lnst/Controller/__init__.py | 2 +- lnst/Devices/Device.py | 48 ++- lnst/Devices/RemoteDevice.py | 36 +- lnst/RecipeCommon/LibvirtControl.py | 41 ++ lnst/RecipeCommon/Perf.py | 90 ++-- lnst/RecipeCommon/PerfResult.py | 10 +- lnst/RecipeCommon/Ping.py | 35 +- lnst/RecipeCommon/TRexMeasurementTool.py | 87 ++++ lnst/Recipes/ENRT/BaseEnrtRecipe.py | 14 +- lnst/Recipes/ENRT/OvS_DPDK_PvP.py | 399 ++++++++++++++++++ lnst/Slave/InterfaceManager.py | 14 +- lnst/Slave/Job.py | 6 +- lnst/Slave/NetTestSlave.py | 81 +++- .../TestModule.py => Tests/BaseTestModule.py} | 20 + lnst/Tests/Iperf.py | 2 +- lnst/Tests/Netperf.py | 3 +- lnst/Tests/Ping.py | 2 +- lnst/Tests/TRex.py | 159 +++++++ lnst/Tests/TestPMD.py | 47 +++ setup.py | 6 +- 34 files changed, 1356 insertions(+), 266 deletions(-) create mode 100644 lnst/Controller/RecipeControl.py create mode 100644 lnst/Controller/SlaveObject.py create mode 100644 lnst/RecipeCommon/LibvirtControl.py create mode 100644 lnst/RecipeCommon/TRexMeasurementTool.py create mode 100644 lnst/Recipes/ENRT/OvS_DPDK_PvP.py rename lnst/{Common/TestModule.py => Tests/BaseTestModule.py} (85%) create mode 100644 lnst/Tests/TRex.py create mode 100644 lnst/Tests/TestPMD.py -- 2.17.0
