The BG_RECENT_SOURCE (user_data) call was done before it was checked if is was
cancelled. At this point user_data is pointing to an object that has been deleted.
Fixes#729
Monitors may not always have a mode. This means we cannot look up the
mode on the fly, but instead need to have a heuristic to select a mode
if there is none.
Everything was in place already for this, except that one location was
still doing a fresh lookup, possibly causing a crash.
Fixes: #675
localed will not update the LC_* variables if they are not given. This
means that should the user switch the formats away from LANG and then
back, they will not be reset appropriately.
Simply always setting the variables even if the match will fix this.
Instead of using @borders for drag handles, we use @theme_fg_color at 40% opacity. Because these are widgets intended to be interacted with by users instead of drawing borders, we should use a semantically appropriate color which updates according to whether a user has a dark theme selected or not. This ensures that the drag handles contrast with the background no matter what stylesheet the user is using.
This improves the contrast of these widgets in the light theme from 1.7:1 to 2.9:1, which is still rather low, but greatly improves the usability of these widgets without having too large an impact on the look of the widgets in-situ. The contrast ratio is unchanged in the HighContrast style (4.0:1).
This also improves the situation if we eventually adopt a dark style preference for users, and improves the portability of the application.
For the "development" profile, lets use the Nightly variant, to
visually indicate to users that they are running an unstable
version of the application.
Since 4.10, Samba supports python3. Therefore we updated "Samba"
here. That required us to bundle lmdb since it is a samba build
dependency. See
https://wiki.samba.org/index.php/Samba_4.10_Features_added/changed
We also disable pam and json to speedup the build and require
less bundled dependencies.
intltool has been removed from the SDK and the release-team has
advised users to bundle it in their Flatpaks until the dependencies
get ported away from it. See
https://mail.gnome.org/archives/desktop-devel-list/2019-August/msg00000.html
This patch also ships with some polkit changes to make it suitable
for use within Flatpak. These changes were copied from gnome-builder.
