@lbolla Could you please take a quick look at this PR ? This simple export would be really useful for https://github.com/DataDog/nikos that makes use of aptly for downloading kernel to compile eBPF programs. Thanks a lot !

@lebauce, could you please update the commit description with what you are solving specifically? I am interested in use-cases for this. Ideally, this would close a bug describing your problem.

EDIT: This is probably bold, but please consider How to Write a Git Commit Message.

@r4co0n Thanks for taking a look at it.

My goal is to have the full download URL of a package. My library works this way:

I have a deb.RemoteRepo. On this repo, I call

• Fetch
• DownloadPackageIndexes
• I apply a filter using ApplyFilter
• FinalizeDownload
• RefList (I cannot call PackageList as repo.packageList is cleared here : https://github.com/aptly-dev/aptly/blob/master/deb/remote.go#L657)
• NewPackageListFromRefList with the PackageRefList from the previous step

I now have a PackageList. When iterating on this package list, the Packages in it only have the field Filename and Checksums set. Both PoolPath and downloadPath are empty.

So when I call repo.PackageURL, I have an incorrect URL. Something like http://us.archive.ubuntu.com/ubuntu/linux-headers-5.4.0-42_5.4.0-42.46_all.deb instead of http://us.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-headers-5.4.0-42_5.4.0-42.46_all.deb (missing the pool part).

I tried different approaches but none worked : after FinalizeDownload, I can't restore downloadPath (I can use Package.PoolDirectory and RemoteRepo.PackageURL but the component is lost).

Exporting the package list allows using Packages with the downloadPath field set

Thanks!

Thank you @lbolla and @r4co0n !
