API does not include Builds for sources that were copied from a prior release

Isn't that sort of right though? It wasn't build in lucid.

Or to put it another way, isn't it nice to see that it was copied from the previous series rather than build in it?

sigh s/build/built/

It would be good to discuss your use cases in this scenario so I can get a better idea of what you're trying to do :)

My use-case is "download the build for Lucid's 'foo' package":

def get_build_url(pkg, release):
    series = ubuntu.getSeries(name_or_version=release)
    source = archive.getPublishedSources(status='Published', distro_series=series, pocket='Release', exact_match=True, source_name=pkg)
    for build in source_item.getBuilds():
        if build.arch_tag == arch:
            return build.build_log_url

This ends up not working, and instead I need to walk all publications in order to find the first time there is actually a build record:

    for src in archive.getPublishedSources(status='Published', exact_match=True, source_name=source.source_package_name):
        if src.source_package_version == source_item.source_package_version:
            for build in src.getBuilds():
                if build.arch_tag == arch:
                    return build.build_log_url

I guess this might be "by design", but that means that when prior releases vanish, so do the build records? Anyway, it's just wishlist really, since I can work around it; I was just hoping to speed up the queries.

Ok

IBuild has a distroseries property internally that's not exported on the API, so we'll do that so that builds can be distinguished from the current series

Then, we can provide a way of getting a build for a source regardless of the current series.
