    Don't override a Skip selection
    Introduce SolverTasks::taskSkip, and generate it when the user chooses
    to Skip a package that the solver wants to install.  Implement it by
    sending a SOLVER_LOCK command on the package name.;h=70baff902374e45554f0e8370e4c74660731bf61

    Fix the functionality of taskKeep
    A taskKeep is generated whenever the user wants to keep an installed
    version that's different from the default_version, where the latter is
    whatever the solver has chosen.  We need to make sure that
    default_version is set appropriately wherever it is needed.;h=993d4137439152f91ab0438c7a66d54adbbeef41

    Extend the SolvableVersion member functions to the empty package
    Currently some of these functions cause crashes when the package is
    empty because the libsolv function pool_id2solvable unconditionally

    Take command line package/category install/uninstall into account
    Rather than overwriting the packagedb changes made from processing command
    line options in ChooserPage::OnInit(), use the 'initial' flag to
    changeTrust() in createListview() to take them into consideration.

    Use solver for initial pick list when upgrading
    Use the solver to determine initial pick list for Curr or Test, rather than
    directly picking packages. Thus the solver's initial solution in the pending
    view should be the first thing the user sees.
    Note: Keep is magical, and the package db pick list gets reset by
    ChooserPage::keepClicked(), rather than going through changeTrust().
    We don't unify these two paths, because the trust level passed to
    changeTrust() gets recorded in PickView::defTrust and used by the line
    picker in some mysterious way, and seems to only be expected to be
    TRUST_CURR or TRUST_TEST.  There's probably a subtle bug here, in that the
    line picker might behave differently depending on if Curr or Test was
    selected before Keep.
    Drop passing upgrade flag to solver run after the user has made their
    selections: the picker selection now reflects what the user is asking for.;h=ef5e8b956636271a6a817d9052b239500bf3c77a

    Make removeEmptyCategories() explicit, rather than a side effect of defaultTrust()
    It's unclear that this can ever do anything.  The list of categories is
    built as we see packages in those categories, so I don't know how we can

    Handle 'Source:' lines in setup.ini
    This is somewhat awkward:
    Storing the source package by Id rather than by name is looking a bit like a
    premature optimization, but being to able to refer to source packages by Id
    is very handy.
    If the src pkg isn't seen until after the pkg, we don't know what it's Id
    will be.  So we have to go back and fixup the Ids after we've seen all

    transaction list to reflect the package database.  Use it if the user
    refuses the default problem solutions.  Reinstate warning that this

    Improve the reading of installed.db
    When creating a packageversion for a package listed in installed.db,
    use the information for the installed version rather than the
    "current" version.  Add a new function packagedb::findBinaryVersion to

    from the prior reading of setup.ini.
    Improve detection of installed test releases.  An installed test
    release might not appear in setup.ini because it is no longer
    available (e.g., it might have been replaced by a newer test release).

    Download/checksum/install/uninstall what transaction wants
    Some of this goes rather around the houses to avoid lots of churm: In lots
    of cases, we're looking up packagemeta for a given packageversion just so we
    can use the pacakgemeta to access the name, which we could do via
    packageversion just as easily.
    We do actually need packagmeta for a couple of things: To note the package
    as installed/uninstalled, and to note postinstalls scripts.
    If IncludeSource is on source packages installs will have been added to the
    task list in post-processing, so we don't need to handle that specially
    Source packages to be installed are kept in a separate queue as they are
    installed differently to binary packages (root is /usr/src, install isn't
    recorded, etc.);h=aa7b995f5be09d8efad6ced1ab7a6894b5204e83

    Change to using a libsolv pool for storing package information
    Add class SolverVersion, a wrapper around a Solvable Id. The interface is
    similar to class packageversion, the name change is just to make sure I've
    got everything.
    Place test packages into separate repos.
    Expressing that curr: packages are preferred to prev: ones when that is not
    the version number ordering should be done with epoch numbers.
    Wire up various bits of data in packageversion to Solvable attributes,
    including sourcepackage, stability, archive (packagesource) and depends.
    Store sourcePackage() by the id rather than name, for much faster lookup.
    SolverVersions for the same package can be ordered and compared by evr.
    Factor out packagedb:addBinary() and also use it in IniDBBuilder, rather
    that inlining the process of adding a package there. Add an analagous
    packagedb:addSource() to do the same thing for source packages.
    Change to reading installed.db after setup.ini's have been read, so we can
    supplement the installed.db packages with information from setup.ini.
    Make packagemeta::add_version() check for successful insertion of version.
    Record the version at a stability level. The last version wins in setting

    Hoist pick() up to packagemeta
    We are always writing packagemeta.desired.pick(bool, packagemeta).  This
    kind of suggests something not quite right.
    The pick flag means install/reinstall, so despite being stored per
    packageversion, is only significant to download/install for the desired
    There's a slight wrinkle in that we want to also set/clear this flag for the
    source packageversion.  We can't change this to point to packagemeta rather
    than packageversion, as that may not be the same for all versions, so
    instead just track this flag separately as srcpicked.
    Note that there is still a complicated mapping between the state of desired
    and pick and the action represented in the UI:
    desired == empty, installed == desired : skip
    desired == empty, installed != desired : uninstall
    desired == installed, pick == true     : reinstall
    desired == installed, pick == false    : keep
    desired != installed, pick == true     : upgrade

    Rather that doing implicitly the first time a packagedb is constructed, do
    it explicitly at a certain point in time that is early enough.;h=fccc06f0c4b4b7465c7c80a30f65b0099531a176

    Opaque how PackageDepends is stored
    We want to be more opaque about how the PackageDepends for a packageversion
    is stored, so rather than exposing a pointer to a PackageDepends object
    inside class packageversion, access it by value.
    This also makes us be more explicit about set/get of package depends()
    Fix some iterations to deal with depends() returning a value rather than a
    Also adjust dumpPackageDepends() appropriately
    Also remove useless debug showing the dependency list before we build it.
