Switch default version string back to the `-non-git` prefix to indicate
an indev version.
Additionally fix the formatting of the 1.3 header in the changelog.
Dunst does not neccessarily need systemd. Dunst gets started primarily
via DBus. The systemd service is useful on systemd init based systems,
but won't have any impact on non-systemd systems.
To make systemd a soft dependency is neccessary, as pkg-config now also
queries the systemd.pc file, which won't exist on non systemd systems.
Setting PREFIX to a location different to /usr, the install routine
fails to install the systemd and dbus service files. These are
installed, but in the PREFIX directory and not /usr. DBus and systemd
usually only read their files from /usr/ and ignore files in /usr/local.
Now by default, we're asking pkg-config, where to install it. Mostly,
this will be /usr and this conflicts the FHS. But it's the user's intent
to install dunst and (possibly) override the package manager's files
belonging to dunst.
At the current point, even DBus ignores the PREFIX and installs its
systemd service file to the location specified by pkg-config.
When receiving a PropertyChange XEvent, it's mostly because the focus of
another window changed to another window. This isn't actually neccessary
for dunst. We need the event only, to know, when the screens have
switched.
As redrawing the screen became more expensive with the drop of GTK3, we
have to ignore this event and only really redraw the window, when the
focus has moved to another screen.
As per discussion in #334 drop dependency on gtk3 and instead depend
only on gdk-pixbuf2 for icon loading.
The only gtk3 function used was gdk_cairo_set_source_pixbuf in order to
convert the loaded pixbufs into cairo surfaces for us to render. In
order to drop the dependency this step was bypassed by using pixbufs
export to png capability and importing it into cairo via a pngstream.
When the DBus name lost function is called, either the whole DBus
connection is lost, or another rivaling FDN daemon acquired the name.
Without enough experience, this is impossible to trace back and examine
further.
To make it easier for new users, dunst prints out the PID of the
process, which currently acquired the FDN DBus name.
Indentation in travis.yml was inconsistent, update it to consistently
use 2 spaces.
I considered using 4 spaces to be more consistent with the rest of the
project but it looks too spaced out and doesn't suit YAML in my opinion.
The hints given via DBus are not constants. Therefore the color fields
have to get freed during notification cleanup. As it's not possible to
disinguish, which field is constant, we have to duplicate the settings
on assignment.
While the notification spec allows tags like <a href="...">...</a> and
<img src="..." alt="...">, pango cannot parse these tags and therefore
these tags should be removed before passed to pango.
Also the method notification_extract_markup_urls is not needed anymore,
as markup_strip_a can return URLs optionally.
This implies, that URL replacement is now indicated via show_indicators
for URLs and the dmenu string is in the format of
'[text between a tags] URL\n'. This is similarly handled for images,
too.
The signal_notification_closed function is called even when a
notification has been pulled from history and re-emits the
NotificationClosed signal, this can confuse clients since multiple such
signals are not accounted for in the spec.
