class UpstreamRequirement(object):
family: str
class PythonPackageRequirement(UpstreamRequirement):
package: str
SetupPy.get_build_requirements() yields some PythonPackageRequirement objects
apt_resolver.install([PythonPackageRequirement(...)]) then:
* needs to translate to apt package name
Once we find errors during build, buildlog consultant extracts them ("MissingPythonPackage", "configure.ac needs updating").
fix_build then takes the problem found and converts it to an action:
* modifying some of the source files
* resolving requirements
Resolving requirements dependencies means creating e.g. a PythonPackageRequirement() object and feeding it to resolver.install()
we have specific handlers for each kind of thingy
resolver.install() needs to translate the upstream information to an apt name or a cpan name or update dependencies or raise an exception or..
MissingPythonPackage() -> PythonPackageRequirement()
PythonPackageRequirement() can either:
* directly provide apt names, if they are known
* look up apt names
We specifically want to support multiple resolvers. In some cases a resolver can't deal with a particular kind of requirement.
Who is responsible for taking a PythonPackageRequirement and translating it to an apt package name?
1) PythonPackageRequirement itself? That would mean knowledge about package naming etc, is with the requirement object, which seems wrong.
2) PythonPackageRequirement.apt_name(apt_archive) - i.e. find the package name given an archive object of some sort
3) The apt resolver has a list of callbacks to map requirements to apt package names
