Move away from Travis-CI

[hugsy]

Possible alternatives:

• https://codeship.com
• https://drone.io ($$$ - no free offer)
• https://wercker.com (down it seems)
• https://www.gocd.org (In-House but would allows deploying agents on Qemu VMs)

Why the move away from Travis? Have you considered Circle CI?

[hugsy]

Because it's poorly suited for testing gef on multiple architecture and uses super old packages. Not sure I see the difference between CircleCI and TravisCI, can you test on non x86 architectures ? Or at least deploy easily VMs that do?

[cclauss]

If you can put onto https://hub.docker.com a Docker image that houses the environment that you want then both Travis CI and Circle CI can mount it and run the tests inside of it. Pre-built images can have ready-to-run GDB linked into the Python of your pleasure and they will load in seconds. Circle CI might be a bit faster and more modern than Travis CI but both are approx equally capable.

• https://docs.travis-ci.com/user/reference/overview Linux and Mac on x86

[hugsy]

I don't see pros for changing from Travis-CI to Circle-CI to make tests easier (looks 100% the same). And I don't see how Docker would help in any way. Can you clarify that?

[cclauss]

Docker can help because we can:

• build the GDB linked to Python 2 in a Docker image once and test with it 1000 times
• build the GDB linked to Python 3 in a Docker image once and test with it 1000 times
• test start up time takes seconds, not minutes

[hugsy]

I should have been clearer: how would Docker help for testing on non-x86 arch? Which is the whole point of moving away from Travis-CI in the 1st place.

[cclauss]

Would running VMware inside of a Docker container help to simulate non-x86 environments?

• https://hub.docker.com/u/vmware

[hugsy]

AFAIK VMware doesn't do full virtualization, so no. Some examples would be Qemu or Bochs. I've got the Qemu images that I'm already using to test new releases, but I do that manually, and it's very tedious (which explans the will to have it tested via a CI service provider).

[Grazfather]

I am a fan of circle, but probably just because I've used it before.

One issue is that they run everything with docker, and I am not sure if they run them privileged. Without that, ptrace won't work.

[hugsy]

Did you test it for gef ?

[Grazfather]

I pushed a config to dev, and to master on my fork, which is setup for circle. See https://circleci.com/gh/Grazfather/gef/21. The failure is because of a real failure!

Could you please try this out and see if you like it? you'd have to merge this into master, and you'd have to setup a circleci integration/webhook.

Can be closed with #324

[Grazfather]

Done!
