Package retention policy with the ProGet SDK

[Guest]

I am working on a task to create an extension/plugin that does the following:

When a new package is added:

• Identifies prior instances of the package being added
• retain the most recent and “n” number of instances
• removes all other packages

Do you think this can be done using ProGet SDK?

If you so could please direct me on how to write this?

Product: ProGet
Version: 3.1.2

Something like this should work:

sealed class FilteredPackageStore : DirectoryPackageStore
{
    private const int PackagesCount = 5;

    public override Stream Create(string packageId, SemanticVersion packageVersion, bool allowOverwrite)
    {
        var packagesToDelete = StoredProcs.Packages_GetPackages(this.FeedId, "Y")
            .Execute()
            .Where(p => p.Package_Id.Equals(packageId, StringComparison.OrdinalIgnoreCase))
            .OrderByDescending(p => p.Published_Date)
            .Skip(PackagesCount);

        foreach (var package in packagesToDelete)
            this.Delete(package.Package_Id, new SemanticVersion(package.Version_Text));

        return base.Create(packageId, packageVersion, allowOverwrite);
    }
}
