We have many places where we are sending an XCB request and expect an
answer where the protocol guarantees that no error can occur and we are
sure to get an answer. However, for example if the X11 server crashes,
these places can still fail. This commit tries to handle failures at all
these places.
I went through the code and tried to add missing error checking (well,
NULL-pointer-checking) to all affected places.
In most cases these errors are just silently ignored. The exception is
in screen querying during startup. If, for example, querying RandR info
fails, we will fall back to Xinerama or zaphod mode. This is serious
enough that it warrants a warning. In most cases, we should exit shortly
afterwards anyway, because, as explained above, these requests should
only fail when our connection to the X11 server breaks.

The code in luaA_client_swap() is incorrect, because
luaA_object_emit_signal() already pops the arguments to the signal.
Still, the code here tried to remove the arguments from the Lua stack
again, thereby corrupting the stack (removing more items than there are
in the stack).
Normally, popping more things from the stack than it has entries
silently corrupts the Lua stack. Apparently this doesn't necessarily
cause any immediate issues, because this code has been broken since nine
months and no one noticed. This mistakes was introduced in commit
55190646.
This issue was only noticed by accident. Thus, this commit also adds a
small integration test that exercises this bug. This test catches the
issue, but only on Travis, because there we are building our own version
of Lua 5.3 and that one has assertions enabled.

Daniel sees a short flicker of his wallpaper when he closes a client.
This happens because the window is destroyed immediately, but other
clients are re-arranged only shortly later. In the mean time, the X
server updates the display and repaints the root window (= wallpaper
becomes visible).
Work around this by delaying the destruction of frame windows to the end
of the current main loop iteration. This means that we first update the
position of all other windows and later destroy the window that was
actually closed.

This adds a tparam alias "@screen" for "@tparam screen" (when used to
document e.g. arguments for callbacks), and "@screen_or_idx" when a
function accepts a "screen" or "number".
There are some situations where we do things that can make the mouse pointer
enter another window. We do not want to react to these "self inflicted" mouse
enter and leave events, because they aren't "real" (= generated by the user).
Before this commit, this is done by going through all windows and toggling the
"please send us enter and leave events"-bit on them. This becomes slower when
many windows are visible and floods the server with requests.
This commit changes this to a constant-time logic. Each event contains the
sequence number of the last request that the X11 server handled. Thus, we just
remember the right sequence numbers and ignore any events that comes in whose
sequence number falls into the ignored range.
In detail, we keep a list of "begin" and "end" sequence numbers and ignore any
enter and leave events that fall in this range. If we get any event with a
sequence number higher than "end", we remove this pair from the list, since it
is no longer needed.
To generate these pairs, we use a GrabServer request in
client_ignore_enterleave_events(). This gives us a sequence number and makes
sure that nothing else besides us can cause events. The server is ours! In
client_restore_enterleave_events(), we first do a NoOperation request to
generate the sequence number for the end of the pair and then do UngrabServer.
Any event that is generated after UngrabServer will have at least the sequence
number of the UngrabServer request and thus no longer fails between begin and
end.

Commit 7dad0b3b87 made awesome only ask for mouse events on the actual
client window. Obviously, this means that we no longer get reports for clicks on
the titlebar. Whoops.
Fix this by asking for mouse events on *both* the actual client window and the
frame window. The passive grab on the actual client window is actually unneeded,
but we keep it so that the fix that was done by the above commit is still
present (xev will no longer report leave/enter events just for a mouse click).
Since we now get mouse events inside of a client reported twice, the event
handling code in event.c has to be fixed to handle both cases. E.g. x/y are
relative to the top-left corner of the window and thus needs to be fixed for
titlebar size; the second click has to be ignored.

EWMH specifies that
If _NET_WM_WINDOW_TYPE is not set, then managed windows with WM_TRANSIENT_FOR
set MUST be taken as [_NET_WM_WINDOW_TYPE_DIALOG].
We implement this by forcing a window's type to be "dialog" when it has a
WM_TRANSIENT_FOR property. For windows that have a _NET_WM_WINDOW_TYPE property,
this type change is then later undone. However, when a window changes its
WM_TRANSIENT_FOR property during runtime, then we would set its type to "dialog"
unconditionally.
This commit fixes this by explicitly tracking if we found a _NET_WM_WINDOW_TYPE
property on the window and only applying the fallback if we did not find such a
property.

Since commit 102063dbbd, awesome is a reparenting WM. That means that we put our
own frame windows around child windows. This means that we have the option of
grabbing input events on the frame window or the child window. This commit chose
the frame window for this.
For keyboard events, this decision was already reverted in 532ec0cd90. This
commit does the same thing for mouse events.
This fixes the spurious leave/enter events that were visible on mouse clicks.
They occurred because the click activated a passive grab (all mouse events now
"belonged" to awesome). This passive grab caused the X server to inform clients
that they "lost" the mouse pointer (with the detail field set to "a grab
activated").

We once had the problem that with the nvidia blob, the X11 server told us that
"yes, I do support RandR; there is just a single big screen" even though there
were multiple screens and they could be queried for via Xinerama. To work around
this, we started to ignore RandR if it only provided information about a single
screen.
Our long-term goal is to stop restarting on RandR screen changes. Thus, even if
only a single screen is defined during startup, we should still use RandR later
when another screen is added. This means that we cannot just ignore RandR if it
only mentions a single screen.
This commit copies what GTK+ does: If there is an output named "default", then
some compatibility layer is assumed and we ignore RandR.
I have no way to test if this really does the right thing.

Some words about X11 event handling: Every X11 client can select input on any
window. For this, inside the X11 server each window has for each client a
bitmask for the kind of events that this client is interested in. When a mouse
button is pressed inside of a window, a corresponding event is generated for
that window and sent to all X11 clients which asked for
XCB_EVENT_MASK_BUTTON_PRESS. When no client is interested in this event, the
event is propagated to the parent window and the same procedure is done again
here. This continues up until the root window is reached.
Some words about the event masks that awesome uses: For clients, we ask for
button press events on the frame window that we reparent the client window into
so that we get any kind of press on the titlebar (and also events inside of the
client window if the client itself doesn't care for click events?). We are also
interested in button presses / releases on the root window. However, before this
commit, we didn't actually ask for button events on drawins (e.g. the wibox).
This worked fine, because no one asked for these events and the event propagated
to the root window where it was then sent to awesome.
However, newer Qt versions do something weird and the above broke. I don't
actually know what is going on. I know about the above propagation rules, but
looking at protocol traces of what Qt does, awesome should still get the button
events. During startup, Qt asks for button events on its own windows. After a
hotplug event, it asks the same again, but now also includes the root window.
So... how can Qt asking for button events on the root window cause awesome not
to get them? I have no idea.
(And yes, I guess that Qt asking for mouse events on the root window is a bug,
but I have no idea how exactly this happens nor about any other side effects of
it).
This commit makes us ask for button events on our drawins so that the server
will send them to us. This is the right thing to do anyway and it was reported
to have some positive effects.

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.

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))

This fixes the following code:
local d = drawin({})
d.visible = true
The drawin now has a cairo surface assigned
d.visible = false
d.width = 1234
d.visible = true
The width change while the drawin was not visible would not get propagated to
the drawable because of the code that this patch removes. The expectation was
that drawin_map() would update the drawable later.
However, because the drawin was already visible, its drawable also already has
a surface assigned. Thus, drawin_map() wouldn't update the drawable either.
Fix this by just removing this optimizations.

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.

Every .c file has to include the corresponding .h file first to make sure the
headers are self-contained. Additionally, this moves some unneeded includes
around.

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.

We now handle all "important" EWMH messages in lua and lua can decide to do
different things than the current obvious one.
Consistency!

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
end)
