SPP controller 'spp.py' is monolithic and has got to be large. It is
hard to be maintained because several classes are included in the file
and global variables are shared among its instances.
This seriese of update is to move classes and methods in spp.py to
'controller/' as separated files for maintainability. It also includes
additional commands.
Yasufumi Ogawa (13):
spp: move controller to sub directory
controller: move connection threads
controller: aggregate logger to spp_common.py
controller: add load command
controller: move common methods to shell_lib
controller: add filter for py to compl_common
controller: refactor shell.py
controller: change logger output to logfile
controller: add do_topo to shell.py
controller: add topo.py
controller: add topo_subgraph command
controller: add cat and less command
controller: create log directory

SPP controller 'spp.py' is monolithic and has got to be large. It is
hard to be maintained because several classes are included in the file
and global variables are shared among its instances.
To improve maintainability, 'spp.py' is divided into main and class
files. Global variables are also moved to shared file 'spp_common.py'.
This update is halfway for refactoring and classes are going to be
more fine-grained.

From: ogawa.yasufumi @ 2018-03-06 10:50 UTC (permalink / raw)
To: ferruh.yigit, spp; +Cc: Yasufumi Ogawa
From: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>
There are three classes in 'spp.py' for managing connection as threads.
This update is for separating them from main file to improve
maintainability.

Load command is for loading a command plugin. It enables users to
activate a command after SPP controller is launched. Plugin files
are included in 'src/controller/command/'.
This update also includes a sample command 'hello'. It says hello
message with given name.
spp > load hello
spp > hello alice
Hello, alice!

From: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>
Change loading command plugin from usign setattr() to directly assigning
it to Shell class. It is because Shell object provides completion and
showing help only for class methods and does not for methods added with
setattr() mehtod.
This update also includes misc refactoring of whole of shell.py.

'topo' is an experimental command for SPP controller to outptu topology
of network configuration. It enables to display a graphical image of
network configuration on terminal, or browser for which websocket
server is running with.
'topo' command supports four types of output. For multiple output
support, it uses graphviz, imagemagick and other external tools.
* terminal (but very few terminals supporting to display images)
* browser (websocket server is required)
* image file (jpg, png, bmp)
* text (dot, json, yaml)
Here is a list of required tools for 'topo'. Notice that SPP controller
and 'topo' command support MacOS on a remote host.
* graphviz
* imagemagick
* libsixel-bin (for Ubuntu) and terminal app supporting img2sixel
* iTerm2 and imgcat (for MacOS)
For terminal, only few terminal applications are supported. You can use
mlterm or xterm for which 'img2sixel' supports on linux
or iTerm on MacOS. If you use iTerm2, you have to get a shell script
'imgcat' from [1] and save it as
'spp/src/controller/3rd_party/imgcat.sh'.
[1] https://iterm2.com/documentation-images.html
For browser support, you are required to install websocket libraries and
use 'spp_ws' tool. 'spp_ws' is not released yet, but soon.
There are some example usecases.
(1) Display on terminal or browser.
spp > topo term
spp > topo http
(2) Output to a file.
spp > topo myconfig.jpg
spp > topo myconfig dot
This update is only for 'shell.py' and requires a module file 'topo.py'
in which methods for 'topo' command are implemented.

'topo_subgraph' is for defining subgraph of resources in a network
topology generated by 'topo'. Typically it is used for grouping vhost
interfaces of each of VMs or containers to be more understandable the
generated network topology.
Usage: topo_subgraph [VERB] [LABEL] [SUBGRAPH]
VERB: 'add' or 'del'
If you assign vhost1 and vhost2 to VM1, define subgraph as following.
spp > topo_subgraph add VM1 vhost1,vhost2
Or delete defined subgraph.
spp > topo_subgraph del VM1
To show all of defined subgraphs, simply run without arguments.
spp > topo_subgraph
