[Sugar-devel] [PATCH] Added Protected-Activities-Support to sugar (SL#2087)

Excerpts from Kandarp Kaushik's message of Wed Sep 08 19:13:38 +0200 2010:

s/at the list view palette/in the Home View/

The Home View might support additional layouts in the future that show
the erase option as well.

[data/sugar.schemas.in]

Dito.

[src/jarabe/desktop/activitieslist.py]
> +        self._add_erase_option( registry, activity_info )

Please remove the extra spaces after / before parentheses. pylint would
have told you this.

> +        if not activity_info.is_user_activity():
> +            return
> +        if registry.is_activity_protected(self._bundle_id):
> +            return

A newline at this point (i.e. after the last guard) would improve
readability IMO.

[src/jarabe/model/bundleregistry.py]
> +        try:
> +            self._protected_activities = client.get_list('/desktop/sugar/protected_activities',

Line too long (80 chars is the limit). Just put the string literal on the
next line, indented by four additional spaces. If it fits, merge in the
remaining part.

> +                gconf.VALUE_STRING)
> +        except Exception:
> +            self._protected_activities = []

Please only catch specific exceptions, otherwise you might hide some
failures / bugs.

Have we reached consensus on the design, BTW? The patch still hides
the erase option instead of deactivating it.
