      libnm-core: reorder code in settings · 19141ef7
      Thomas Haller authored
      Order the code in our common way. No other changes.
      
      - ensure to include the main header first (directly after
        "nm-default.h").
      
      - reorder function definitions: get_property(), set_property(),
        *_init(), *_new(), finalize(), *_class_init().

      Thomas Haller authored
      Unify the coding style for class-init functions in libnm-core.
      
      Also make use of obj_properties, NM_GOBJECT_PROPERTIES_DEFINE(), and

      libnm: rework setting metadata for property handling · 37938043
      Thomas Haller authored
      NMSetting internally already tracked a list of all proper GObject properties
      and D-Bus-only properties.
      
      Rework the tracking of the list, so that:
      
      - instead of attaching the data to the GType of the setting via
        g_type_set_qdata(), it is tracked in a static array indexed by
        NMMetaSettingType. This allows to find the setting-data by simple
        pointer arithmetic, instead of taking a look and iterating (like
        g_type_set_qdata() does).
      
        Note, that this is still thread safe, because the static table entry is
        initialized in the class-init function with _nm_setting_class_commit().
        And it only accessed by following a NMSettingClass instance, thus
        the class constructor already ran (maybe not for all setting classes,
        but for the particular one that we look up).
      
        I think this makes initialization of the metadata simpler to
        understand.
        Previously, in a first phase each class would attach the metadata
        to the GType as setting_property_overrides_quark(). Then during
        nm_setting_class_ensure_properties() it would merge them and
        set as setting_properties_quark(). Now, during the first phase,
        we only incrementally build a properties_override GArray, which
        we finally hand over during nm_setting_class_commit().
      
      - sort the property infos by name and do binary search.
      
      Also expose this meta data types as internal API in nm-setting-private.h.
      While not accessed yet, it can prove beneficial, to have direct (internal)
      access to these structures.
      
      Also, rename NMSettingProperty to NMSettInfoProperty to use a distinct
      naming scheme. We already have 40+ subclasses of NMSetting that are called
      NMSetting*. Likewise, NMMetaSetting* is heavily used already. So, choose a
      new, distinct name.

      libnm: use NMMetaSettingInfo for tracking setting priority · 9c47e2ce
      Thomas Haller authored
      Previously, each (non abstract) NMSetting class had to register
      its name and priority via _nm_register_setting().
      
      Note, that libnm-core.la already links against "nm-meta-setting.c",
      which also redundantly keeps track of the settings name and gtype
      as well.
      
      Re-use NMMetaSettingInfo also in libnm-core.la, to track this meta
      data.
      
      The goal is to get rid of private data structures that track
      meta data about NMSetting classes. In this case, "registered_settings"
      hash. Instead, we should have one place where all this meta data
      is tracked. This was, it is also accessible as internal API,
      which can be useful (for keyfile).
      
      Note that NMSettingClass has some overlap with NMMetaSettingInfo.
      One difference is, that NMMetaSettingInfo is const, while NMSettingClass
      is only initialized during the class_init() method. Appart from that,
      it's mostly a matter of taste, whether we attach meta data to
      NMSettingClass, to NMMetaSettingInfo, or to a static-array indexed
      by NMMetaSettingType.
      
      Note, that previously, _nm_register_setting() was private API. That
      means, no user could subclass a functioning NMSetting instance. The same
      is still true: NMMetaSettingInfo is internal API and users cannot access
      it to create their own NMSetting subclasses. But that is almost desired.
      libnm is not designed, to be extensible via subclassing, nor is it
      clear why that would be a useful thing to do. One day, we should remove
      the NMSetting and NMSettingClass definitions from public headers. Their
      only use is subclassing the types, which however does not work.
      
      While libnm-core was linking already against nm-meta-setting.c,
      nm_meta_setting_infos was unreferenced. So, this change increases
      the binary size of libnm and NetworkManager (1032 bytes). Note however
      that roughly the same information was previously allocated at runtime.

      libnm/trivial: cleanup variable names in settings' class-init functions · 23adc373
      Thomas Haller authored
      - Don't use @parent_class name. This local variable (and @object_class) is
        the class instance up-cast to the pointer types of the parents. The point
        here is not that it is the direct parent. The point is, that it's the
        NMSettingClass type.
        Also, it can only be used inconsistently, in face of NMSettingIP4Config,
        who's parent type is NMSettingIPConfig. Clearly, inside
        nm-setting-ip4-config.c we wouldn't want to use the "parent_class"
        name. Consistently rename @parent_class to @setting_class.
      
      - Also rename the pointer to the own class to @klass. "setting_class" is also the
        wrong name for that, because the right name would be something like
        "setting_6lowpan_class".
        However, "klass" is preferred over the latter, because we commonly create new
        GObject implementations by copying an existing one. Generic names like "klass"
        and "self" inside a type implementation make that simpler.
      
      - drop useless comments like
      
           /* virtual functions */
           /* Properties */
      
        It's better to logically and visually structure the code, and avoid trival
        remarks about that. They only end up being used inconsistently. If you
        even need a stronger visual separator, then an 80 char /****/ line
        should be preferred.

      libnm: avoid constructor function for registering NMSetting types · fa9fe466
      Thomas Haller authored
      constructor functions are ugly, because code is running before
      main() starts. Instead, as the registration code for NMSetting types
      is insid the GType constructor, we just need to ensure at the
      right place, that the GType was created.
      
      The right place here is _register_settings_ensure_inited(), because
      that is called before we need the registration information.
