When minimizing a client, we temporarily ignore events for the client window (so
that we don't get the UnmapNotify event that we are causing for the unmap) and
for the root window (I don't actually know why, no "harmful" events should be
caused...).
However, we weren't ignoring events on the frame window itself. This commit
fixes that oversight.
The problem here is that the pointer could be inside the window that is being
minimized. When we then unmap said window, the pointer will now be inside of the
frame window and the X11 server will thus generate an EnterNotify. When we
handle this event later on, we emit mouse::enter on the client and e.g. the
default config then focuses this client, which undoes the minimization.
This fixes a regression introduced in commit 3aeac3870c and fixes#92.

This fix two things:
(1) Clients asking to be urgent while focussed, this have been reported
a few time for urxvt and I usually link a patch that fix this. This may
not be considered a bug by some, but I think it is.
(2) Add the ability to stop noisy clients from setting the urgent state
themselves.
Because ICCCM pretty much mandates that minimized (aka "iconic") clients are
unmapped. In detail: To go back to normal state, the client should map its
window and for this to work, the window needs to be unmapped.

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

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

uploads.
This also makes awesome only update the affected area when it gets an expose

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.

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

This moves the loading of the rc.lua and managing of pre-existing clients to
after we ungrab the server during startup. To make sure we have no races with
clients which start up parallel to awesome, we do the QueryTree for all the
clients that we have to manage before the ungrab, but start managing the clients
only after the ungrab.
This means that we have already selected our event mask on the root window in
scan() and thus received an UnmapNotify event when we reparent windows into a
frame window. This has the effect that we immediately unmanage the client again,
whoops.
To fix this, we grab the server again and remove our event mask on the root
window again while we reparent.

pulseaudio wants to talk to the X server, but is being ignored because we have

When one sets a client to fullscreen, this is what currently happens:
- lua code: c.fullscreen = true
- The C code emits request::fullscreen without having touched the client's
fullscreen property yet (c.fullscreen is still false)
- awful.ewmh changes the client's geometry to fullscreen via c:geometry()
- This causes property::geometry to be emitted
- awful.layout reacts on this and causes the screen to be re-arranged, undoing
the fullscreen geometry set in awful.ewmh
- The C code for c.fullscreen = true continues and actually changes the client's
fullscreen flag
The result of this is that we get a client which thinks it is fullscreen'd
without actually being that.
Fix this by first changing the client's fullscreen property and then emitting
request::fullscreen. Same thing for maximized_{vertical,horizontal}.
