Applying continuous integration to Epiphany / Parallella sof

[snim2]

Continuous integration is popular and there are several free tools for performing CI on Free software.

I have put together a proof-of-concept for travis-ci, a popular, cloud-hosted CI tool. This uses my Docker image (see the other thread) and builds the "hello world" app from the official Epiphany examples repository.

You can find my Travis config here:



And the current status of that project can be seen on Travis here:



At the moment this is quite basic, it only builds a project it doesn't perform any testing or simulation. If anyone has any clever ideas for enhancements I'd love to hear them!

Cheers,

Hi snim2,

I have make this testing on RPi. Maybe it also works on Parallella.
Run RPi Raspbian by Docker on X86 Linux, not QEMU ~~~

sudo apt-get install qemu-user-static
sudo docker run -it --rm -v /usr/bin/qemu-arm-static:/usr/bin/qemu-arm-static philipz/rpi-raspbian bash

Hi Philip,

I've never used qemu before so I'm not sure what your screenshot shows. Are you running a RPi emulator inside a Docker container? That sounds extremely cool for testing RPi code automatically. Do you know if anyone has attempted a qemu for the Parallella?

Cheers,

Sarah

Hi Sarah,

This is very cool! Making the cross compilation and installation easier is definitely a priority!

As a heads up, we are working on a fresh start to the Parallella (and Epiphany) SDKs. We really want this to be a broad community effort from day one. I would love to see your docker build flow as part of this new "PAL" SDK under development. Of course you could continue to keep it separate, but I think it will be more efficient for all if it's an integrated part. (also, want it to be known that the door is open and everyone is welcome into this new project:-)

This sounds extremely cool. I had seen the pal repository but it wasn't clear to me that it was intended to be a replacement SDK. I'll certainly have a closer look.

At the moment my travis recipe can cross-compile a C program for the Epiphany / Parallella, but it can't unit test or emulate the resulting executables. If you have any thoughts on that I'd be very interested to hear them.

Cheers,

Sarah

Sarah,
What about the "e-run" functional simulator? It only runs Epiphany programs, but it might be a start..

That sounds like a plan, although even with -D -v there isn't a huge amount to see.

Some of the examples in the "examples" repo don't build on my Docker environment and they all have slightly different build recipes. Many have separate build and run shell scripts but some have Makefiles, etc. I think it would be useful to tidy this up and make sure every example is consistent and still works with the current SDK.

I don't have time to do that right now, but maybe in a few weeks time I could have a go. Is there any issue with licensing or is the whole repo under the GPL?

Thanks,

Sarah

[aolofsson]

Agree on the examples part. This definitely needs clean up...

The PAL repo is Apache 2.0...so this might be a reason to keep them apart?

Andreas

Oh sure, I wasn't suggesting merging those repos.

I have other deadlines this week but expect to be pretty active after that. I'll see if I can fit in some time to look at the examples repo.

BTW why are the epiphany-examples and parallella-examples repositories separate?

Cheers,

Sarah
