Package: python-apt
Version: 0.7.13.3
Severity: wishlist

Currently both, the highlevel apt module as well as  apt_pkg, provide
very basic access to the "update" requirement.

apt.py only has a single method, update, that just updates your
database.
res = self._cache.Update(fetchProgress, self._list, pulseInterval)

apt_pkg also have something very similar.

There doesn't seem to be a good way to fiddle with the cache like it can
be done for cache.Packages.

My ultimate goal is to have a replacement for the following in python-apt:
`apt-get -qq --print-uris update`


Regards,
Ritesh

Use apt_pkg.SourceList / apt_pkg.GetPkgSourceList() objects, load the list
using read_main_list() / ReadMainList()  and then use get_indexes/GetIndexes()
on a fetcher. This can be very easily translated from DoUpdate in APT's
cmdline/apt-get.cc and results in:

Using python-apt >= 0.7:
    acquire = apt_pkg.GetAcquire()
    slist = apt_pkg.GetPkgSourceList()
    # Read the list
    slist.ReadMainList()
    # Add all indexes to the fetcher.
    slist.GetIndexes(acquire, True)

    for item in acquire.Items:
        print item.DescURI

Using python-apt 0.8:
    acquire = apt_pkg.Acquire()
    slist = apt_pkg.SourceList()
    # Read the list
    slist.read_main_list()
    # Add all indexes to the fetcher.
    slist.get_indexes(acquire, True)

    for item in acquire.items:
        print item.desc_uri


Closing the bug.
