Everything that needs the lua_State should create a local variable like this:
lua_State *L = globalconf_get_lua_State();
This ensures that the compiler warns if there are two variables with name "L" in
scope. The idea here is that it should become harder to accidentally use the
global lua state instead of the state of the current state.
While writing this commit, I found another place that gets its wrong: Reading
client.focus from a coroutine was broken, since it was returning the result on
the main thread instead of the current one.

tag_client() said that it refers to the tag ontop of the lua stack. However, it
implicitly used globalconf.L as its stack. So if you tagged a client with a tag
from a coroutine, thinks would Go Wrong (tm). Fix this by adding an explicit
lua_State* argument.
Signed-off-by: Uli Schlachter <psychon@znc.in>
A stack index without the corresponding lua_State pointer is useless, because it
could reference another coroutine than the main thread and thus just assuming
globalconf.L is wrong. Fix this by also passing around the corresponding
lua_State pointer.
This improves the result for the following test:
coroutine.resume(coroutine.create(function()
drawin({}).visible = true
end))

Every .c file has to include the corresponding .h file first to make sure the

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.

We now handle all "important" EWMH messages in lua and lua can decide to do

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.

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

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.

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.

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.

Fullscreen clients shouldn't be decorated, thus hide titlebars on those.

The code was sending out ConfigureNotify events which contained the size of the

This commit makes it possible to add titlebars to a client. These titlebars are
drawables.
The drawin's input handling is moved to the drawable. This allows it to use the
same code for drawin and titlebar input handling, although there are lots of
differences between the two on the C side.
On the lua side, a new wibox.drawable module is created which handles all the
drawable-specific magic and which can also be used for titlebars.

When something gives the input focus to the client which already has the input
focus, bad things can happen. Normally, you'd expect nothing to happen in this
case, but X11 is not that simple.
When updating the input focus and the focused client has the nofocus hint set,
we are actually taking away the focus from this client.
Hopefully this fixes FS#973.
