Allow an option to refresh cache before checking

[Vadim Peretokin]

Please add an option "?refresh=yes" to apturl, such that it refreshes the cache before checking if the package exists.

This scenario is necessary when the repository is frequently updated with new programs and the web interface relies on apt links for package installation.

[Vadim Peretokin (vperetokin)]

Here's a patch.

In Parser.py, change the AptUrl class to be:

class AptUrl(object):
    " a class that contains the parsed data from a apt url "
    def __init__(self):
        self.package = None
        self.schema = None
        self.keyfile = None
        self.minver = None
        self.repo_url = None
        self.refresh = None
        self.dist = '/'
        self.section = []

And in apturl, change code starting from 266 to be:

        # FIXME: ask before adding stuff to the sources.list
        # check if we need to fiddle with the sources.list
        if apturl.section and apturl.repo_url is None:
            ret = enable_section(apturl, cache)
            if ret != RESULT_OK:
                error(_("Enabling '%s' failed") % ",".join(apturl.section))
                continue
            cache = apt.Cache()
        # FIXME2: this has security implications, not enabled
        #elif apturl.repo_url is not None:
        # if not enable_repo(apturl):
        # error(_("Enabling '%s' failed") % apturl.repo_url)
        # continue
        # run_update(dia)
        elif apturl.refresh is not None:
         run_update(dia)

Has this bugfix made it into Jaunty through the regular updates or does one need to add some repository to pick this up ?

I have a Jaunty virtual machine with the latest updates I think. When installing the Jaunty version of GNUmed (0.3.9), adding the GNUmed PPA and trying to install GNUmed 0.6.0 from the PPA through

http://wiki.gnumed.de/bin/view/Gnumed/InstallerGuideHomeShort#ubuntu

it complains that gnumed-client is installed already.

Thanks,
Sebastian
