This is specific to GitHub. Please turn this into an interface (e.g. with only the Clone function) such that we can determine which one to use based on the URL or whatever parameter we get.

I did something different, ie added CloneOptions with the provider as an option. Please let me know if that looks good

I could not make integration tests for the private repository work. With some cursory investigation, I found out that it's probably the GITHUB_TOKEN that allows the CI runner to download private repos, which is not something the git CLI will support. Manually tested however |

To create an integration test for cloning private repositories, we can create a new deco account on github, and add that to our test infra. WDYT? |

It assumes it's always github but it can be GitLab for example or any other provider, right?

Yes, we can add support for gitlab as a followup. gitlab also support zip downloads, and for other providers like bitbucket we can defer to the CLI

I would call it "downloadRepo" or something like this, because clone assumes we do the git operation while we don't
| zipDst := filepath.Join(tmpDir, opts.RepositoryName+".zip") | ||
|
|
||
| // Download public repository from github as a ZIP file | ||
| err := download(ctx, opts.zipUrl(), zipDst) |

Shall we have a timeout for download operation?

This would work only for Github, right?

Yes, gitlab has a different format for zip URLs

Why do we support only Github?

Just as a starting point, followups coming soon :)

But design of this code is very tightly coupled with Github specific implementation. If we plan to support other providers, shall we abstract this with some type Provider interface? You could have some implementation specific logic like zipUrl and etc in the implementation of this interface, so later when you decide to add GitLab support you will just need to extend and modify the code

I left some inline suggestion on how to make it more flexible and rely less on implementation details

Add
type provider interface {
repoUrl() string,
zipUrl() string,
destination() string
}
| TargetDir string | ||
| } | ||

replace with

I had a discussion with @pietern and based on feedback from @lennartkats-db we decided to not support ZIP downloads right out of the gate. Lets start with git CLI by default, and switch over to supporting ZIP downloads if there's a need based on customer feedback. This PR is being closed in favour of #544 |
