The code in drawin_moveresize() tries to be clever and only updates the drawing
state of the drawable when it is resized, not when it is moved around. This used
to be necessary because once upon a time, drawin_update_drawing() threw away all
of the drawing state and thus forcing a repaint. These days it just calls
drawable_set_geometry() as well and that function special-cases moves.
So this old code in drawin_moveresize() is no longer necessary and actually
caused problems.
These problems occurred because drawin_update_drawing() is being clever and
doesn't do anything for .visible = false drawins, because their drawing state
will be updated once they become visible. However, not skipping
drawable_set_geometry() means that this broke, because drawin_map() thought that
the drawing state was up to date while in reality it wasn't.

The screen_output_t* that is passed to screen_output_wipe() points into the
middle of the output array table and is a pointer that we never allocated.
Instead, what we want to free here is the name of the output.
Thanks to luzie for reporting this.

The only caller for drawin_unref_simplified() is in ARRAY_FUNCS() and here it is
only used in the implementation of drawin_array_wipe(). However, this function
is unused and thus we don't need drawin_unref_simplified() either.

This makes the screen objects use our existing infrastructure for implementing
classes and objects with lua instead of hand-rolling an own version.
This results in some small API change: Screen objects no longer have an
add_signal() function and instead this function exists on the parent screen
class.

Previously we would get a short black flicker when a client closes. This
happened because first the client's window would get hidden and only a short
moment later would awesome react to this and close its own window. In the mean
time, the X server filled the frame window with its background-pixel which was
black.
Just removing the background-pixel means we get the default value which is None.
This means that the content will be left untouched and the client's window will
be visible for a moment longer.

The X11 server tells us about things that need to be redrawn via expose events.
When we get such an expose event before lua drew the drawable, we just fill the
exposed area with old data (which is black for newly-created drawables).
Fix this by tracking if we have any usable data in a drawable's double buffering
pixmap. This flag is unset whenever we throw away the old content (e.g. due to a
resize) and is set when lua gave us some new content to display.

Previously, ownership of the pixmaps that we are using for double buffering was
a little weird. The pixmap belonged to the drawin/titlebar, but the
corresponding cairo surface was owned by the drawable. Clean this up by moving
the pixmap to the drawable.
This cleans up lots of ugly code and also fixes a crash: When a drawable was
garbage collected before its drawin, drawin_wipe() would crash accessing the
drawable. This was needed to make it forget about the cairo surface we gave to
it for the pixmap that is being destroyed.
By moving the pixmap to the drawable, this whole issues goes away.

Whenever a titlebar of a client needed to be refreshed, all (possibly) four
titlebars would get completely refreshed. So if someone actually added more than
one titlebar to a client, awesome would copy each titlebar's content to the
window four times. Fix this by introducing more fine-grined functions for
uploads.
This also makes awesome only update the affected area when it gets an expose
event for a titlebar instead of all four titlebars completely.

Before this commit, we always threw away the drawin's cairo surface whenever it
was made visible and thus forced a redraw.
This commit changes this so that we only force a redraw if the drawin was
resized why it wasn't visible. To remember when this happens, we free the
drawin's cairo surface without allocating a new one when the drawin is resized
while not being visible. Thus, we then only have to allocate a new surface if
the drawin doesn't have one when it is being made visible.

This allow to spawn something, then apply some properties or rules when
the client show up ("manage").
This commit add:
* "startup_id" property for all clients object (immutable, can be nil)
* Second return value to awful.util.spawn() with the startup_id
* Update the documentation
Example:
local wait_for_it = {}
local pid,snid = awful.util.spawn("urxvtc")
wait_for_it[snid] = {ontop=true,sticky=false,
tag = awful.tag.gettags(mouse.screen)[1] }
client.connect_signal("manage", function (c, startup)
if c.startup_id and wait_for_it[c.startup_id] then
for k,v in pairs(wait_for_it[c.startup_id]) do
c[k] = v
end
if wait_for_it[c.startup_id].tag then
c:tags({wait_for_it[c.startup_id].tag})
end
end

Instead of having the C code mess with which tags are selected, we now emit a
signal on the tag that says that something requested it to be selected. Lua can

This commits adds awesome.register_xproperty(). This allows lua code to register
arbitrary X11 properties with awesome which will then watch these properties.
Whenever such a property is changed on a client or drawin, we will emit the
xproperty::name signal.
This also adds window:get_xproperty(name) and window:set_xproperty(name, value)
which allows to mess with properties.

When we receive a _NET_ACTIVE_WINDOW request on the root window, we used to just
focus and raise the window. This didn't do much for clients which are on
non-selected tags.
Thus, this commit makes awesome emit request::activate on the client instead.
This is used in awful.ewmh to implement the old behavior again, but with
additionally marking the client as urgent if it isn't visible.
People who don't like this behavior can use client.disconnect_signal to disable
this behavior again. To make this really possible, awful.ewmh becomes a
"non-nil" module.

A drawin's and a client's bounding and clip shape can now be queried and is
returned as a cairo surface. Also, a client window's shape (e.g. xeyes setting
its own shape) can be queried via c.shape_client_bounding and
c.shape_client_clip. All of these properties now emit signals when changed.
(This also silently fixes a bug in luaA_drawin_set_shape_bounding() which forgot
to include the drawin's border in its size calculation)

This reverts commit c3bca6ac34.
This caused problems where clients would always spawn on the top-left screen and
couldn't be moved around. This was because lua placed them on the other screen,
but when the titlebar got added, their top-left corner was moved over again.
This kind of forces every client to have a window gravity of "static".
This fixes most of the problem of clients moving around across restarts due to
the titlebar. What is left is that they move due to the border width which
should be handled in another patch. Also, another patch should make this honor
the client's actual window gravity.

Thanks to Michael Stapelberg, there is now a xcb-only port of libXcursor which
does everything we need. This patch switches awesome over to that new library.
Since the only reason for using XOpenDisplay() instead of xcb_connect() was so
that we can use libXcursor, we can get back to that older state again. This
means that this effectively reverts the following commits:
531f8b415c "Added initial support for Xlib cursor themes"
77243cd09a "Add x11-xcb to the pkg-config checks"
779d43fc46 "Don't let Xlib own the event queue"

We no longer have to turn the client's content into an image buffer "by hand".
Instead, we can just use cairo for the job.
Even more exciting, we don't need to turn this into an image buffer at all. We
can just directly return a cairo xcb surface for the client window. Depending on
how lua will use this surface, this could make it possible to avoid having to
create the image buffer at all!

The size saved in c->geometry also includes the titlebars. Thus, for getting the
window content, we have to subtract this from the size.
Before this, the call to xcb_image_get() was failing with a BadMatch error,
because we were asking for an area that is outside of the actual client's
window's geometry.

I noticed high CPU usage while using asunder. The reason was that asunder
re-sets its window name every 0.1 seconds (and awesome's drawing code is way too
slow).
A semi-fix for this is to ignore string property changes if the old and new
value for the property are equal.

Having this in lua means that size hints are only applied after the client got

When property::surface is emitted, the drawable didn't know its geometry yet,
which had weird side effects. Fix this by changing the C API a little. The
function drawable_set_surface() now no longer allows a NULL surface as its
argument.
The required changes for the titlebar code also means that we no longer throw
away the double-buffering surface when a client is moved.

This commit ports awesome from libev to the glib main loop. This means that
awesome has fewer dependencies, because we were already depending on glib before
and now no longer need glib.
However, the main reason for this change is that, thanks to lgi, we have glib
bindings for lua. This means that lua code can add all kinds of event sources to
the main loop (timeouts, fd watchers, SIGCHLD watchers, ....). Yay

The code assumed that a window gets resized when it enters/leaves the fullscreen
mode. This was needed because the code for resizing a window hides and shows the
titlebars.
However, it is possible for a window to enter/leave fullscreen mode without
getting resized, because it already has the correct geometry. In this case,
titlebars were not handled correctly.
This commit fixes that by forcing a resize to the current geometry when the
fullscreen flag is toggled.
