On Continuous Integration

[felix91gr]

@vknabel had a really great idea about how to add CI such that we could test the projects both periodically and before merging a PR, to see that they worked on both Darwin and Linux.

These are the benefits:

• This helps us maintain our goal of listing cross-platform libraries.
• This helps a contributor (and us!) know what might be missing in a newly added project, instantly and with extensive feedback.

And this is (more or less) the idea as I can recall it:

• Parse the document for links, and check if the repo has the structure of a Swift SPM project. If not, whatevs.
• If yes, then download it and run swift test. Collect the results (passed/total and console output) into a list.
• Display the results in the PR.

This would be enhanced by tools such as that described by #31

A draft of the current approach is located here:

The problem is using danger swift: I could not get it running https://travis-ci.org/vknabel/awesome-system-swift/builds/370196293

(Sorry if my writing has been sloppy, when I wrote these issues I was very tired)

Do you think it's possible to do this? Tell me where can I help you :)

No worries :)

I got Danger-Swift to work for now.
Though I use NSURLConnection.sendSynchronousRequest in order to download the pr-diffs.
Sadly it is not available on linux. Can you have a look on this?

Awesome!

And,

Can you have a look on this?

Sure :) I have to leave for class soon, but I'll be back later. I'll check it out then!

That function seems to be deprecated, take a look at this.

I'm going to check out what the Web projects like Vapor and Kitura do. In the case there's nothing Swift-based we could use (which I don't believe is likely), we at least have the CCUrl wrapper that IBM made as a last resort.

[felix91gr]

Huh. Seems like the entire NSURLConnection API is getting slowly deprecated. The replacement for it is based around URLSession, which in the corelibs-foundation repo seems to be mostly complete (open and then Ctrl + F: "urlsession" for the details). Do you think we could use that instead?

[felix91gr]

As an alternative, I've found Vapor's HTTPRequest. Since Vapor's API is 100% implememted, that's a solid option if the corelibs-foundation alternative can't be used.

[vknabel]

Thanks a lot. I used URLSession and semaphores to get the synchronous behavior.

My testing PR did actually pass. 🎉
Now I need to start playing around and improve some parts (compile errors should fail, but missing tests should just warn)
