This removes the libcough which was a temporary layer atop the libpneum to make it synchronous. Now Lua API only requres luajit, and has no dependencies on compiling any C. Also comment out a couple of debug print functions. Change-Id: I35fd1c8088c6fd1b10b9e4d903ad241ab32fd91a Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

This is the experimental version of Lua API, aimed for the luajit use.

|
|
Please take a look and send the feedback to ayourtch@gmail.com.

|
|
|
To run the examples here:
|
|
|
|
1) install luajit - "sudo apt-get install luajit" on ubuntu
|
|
|
|
2) "make build-vpp-api" in the top VPP directory
|
|
|
|
3) "make run" in a separate terminal window
|
|
This ensures you have an instance of VPP running
|
|
|
|
4) sudo luajit examples/example-cli.lua
|
|
|
|
This will result in something like this:

5) You can also run the performance test bench:
|
|
|
|
$ sudo luajit bench.lua
|
|
10001 iterations, average speed 5624LL per second
|
|
10001 iterations, average speed 6650LL per second
|
|
10001 iterations, average speed 6053LL per second
|
|
10001 iterations, average speed 7056LL per second
|
|
10001 iterations, average speed 6388LL per second
|
|
10001 iterations, average speed 5849LL per second
|
|
10001 iterations, average speed 6321LL per second
|
|
10001 iterations, average speed 6368LL per second
|
|
10001 iterations, average speed 5958LL per second
|
|
10001 iterations, average speed 6482LL per second
|
|
Average tps across the tests: 6274LL
|
|
|
|
Note: the above is run in an lxd container running inside 2-core
|
|
xhyve VM on a Macbook Pro, so I would not take the performance numbers for granted :)

|
The "examples" directory contains a few naive examples, as well as a couple of more
|
|
advanced ones - a tab-completing CLI for VPP that can call both the APIs and CLI,
|
|
and also a small test utility which I use for automating some small tests using
|
|
VPP.
