When an imagebox was drawn with width or height zero, it tried to calculate the
needed scale factor for making the image fit. Sadly, this would be a division by
zero aka infinite in this case.
Fix this by just not drawing anything if there is no space available.

Since commit 5b4666432f, we use set_text() instead of set_markup()
on the tooltip's textbox. This means it is no longer possible to use pango
markup in the tooltip which was not intended.
Fix this (properly) by introducing a :set_markup() function on tooltips (and use
it in the timer function to restore the old behavior).

This inlines the set_defaults() function into its only caller and makes us less
stupid with the font property.

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.

This makes gears.color() cache patterns in a weak table and returns that cached
pattern when we get called with the same argument again.
To benchmark this change, the following code was used:
local time = require("socket").gettime
function benchmark(func)
local begin = time()
local iter = 0
while time() - begin < 1 do
func()
iter = iter + 1
end
return iter
end
for _, arg in pairs({
"#00aa00",
"solid:#00aa00",
"radial:50,50,10:55,55,30:0,#ff0000:0.5,#00ff00:1,#0000ff",
"linear:1,2:3,4:0,#000000:1,#ffffff",
"png:/home/psychon/Wallpaper/Bars.png",
{ type = "solid", color = "#00aa00" },
{ type = "radial", from = { 50, 50, 10 }, to = { 55, 55, 30 }, stops = { { 0, "#ff0000" }, { 0.5, "#00ff00" }, { 1, "#0000ff" } } },
{ type = "linear", from = { 1, 2 }, to = { 3, 4 }, stops = { { 0, "#000000" }, { 1, "#ffffff" } } },
{ type = "png", file = "/home/psychon/Wallpaper/Bars.png" },
}) do
collectgarbage("collect")
print(benchmark(function() gears.color.create_pattern(arg) end), arg)
end
Before this change (larger numbers are better, this measures how many times we
can create the given pattern per second):
29525 #00aa00
29344 solid:#00aa00
3446 radial:50,50,10:55,55,30:0,#ff0000:0.5,#00ff00:1,#0000ff

3868 table: 0x1bb6830
5339 table: 0x1bb6c60
32772 table: 0x1bb6fe0
After this change:
126188 #00aa00
125962 solid:#00aa00
125125 radial:50,50,10:55,55,30:0,#ff0000:0.5,#00ff00:1,#0000ff

125249 table: 0x12326d0
125468 table: 0x1232b00
113711 table: 0x1232e80
As you see, this makes some cases about 35 times faster (although I have to
admit that something like this can be expected from such a synthetic benchmark).

Instead of loading files from disk every time we need them, add a cache to
gears.surface as a weak table that maps strings to cairo surfaces.
If this cache should be avoided, there is a new gears.surface.load_uncached()
function which works just like gears.surface.load() worked before.

The bugs this fix are:
* Invalid request using nil as screen
* Stop messing indexes in the old screen
* Prevent c.screen <-> t.screen mismatch
* Prevent no tags being selected in the old screen
When a screen doesn't have any tags selected, then just tag the new client with
all of the screen's tags. That way, we don't lose clients.
Also, if we failed at coming up with tags for a client, don't completely untag
it. This means that it can keep its old tags if it had any.

This reverts commit bbe86e4e25. That commit caused
unintuitive, special behavior. Instead, when someone wants us to set a screen,
we really should do so.
This commit partly reverts commit b4c83d0e70.
Because the C code emits property::screen before manage, this caused
awful.tag.withcurrent() to run on a client before it really was being managed.
This then tagged the client. Because of this tag changes, awful.layout reacted
and ran the layout code. Because c.type wasn't set up at this point yet, the
client wasn't considered to be floating yet. This caused the client's geometry
to change and thus its floating geometry was messed up.

The current premise is that c.screen should be the same as
awful.tag.getscreen(t).
The addition in `ewmh.tag` appears to be the important part here,
changing the order in awful.rules.execute is (maybe) only for
consistency across the codebase.
By default, tag.history.restore switches between the previous history
states, which is not what should get done when deleting a tag.
Without this, deleting multiple tags in a row, will jump back to the
first/fallback tag, instead of the older history entries.
This expands the tilde in the path to beautiful.init and changes the
expansion in theme values to only match '^~/': tilde expansion is only
meant to be expanded at the beginning.
The latter is not really tested.

awful.tag.getscreen(t).

Previously, odd things could happen if a widget was getting fitted into a
negative width or, even worse, width being NaN (not a number)!
This can e.g. happen due to a margin layout which doesn't get enough space to
even draw the margin that it is supposed to add.
Fix this by enforcing a minimum value of 0 for the width and height that a
widget gets fitted into.

Given an imagebox i with i.resize_forbidden = false and a valid image set, the
call t:fit(0, 0) would return two times "not a number".
This is because the code first does some calculations to get the input image
into the available space and then tried to do some calculations needed for
scaling images up.
The first calculation already gave us h == 0 == w, the second calculation would
then calculate 0/0. This results in NaNs.
This was only noticed because NaN is not a valid table index in lua.
Fix this by returning 0,0 if we have an image of width or height 0 after the
first calculation. Since 0x0 images are valid in cairo, this also fixes the same
bug with such images.

There is a strong hint that you are doing something wrong: You call
client.emit_signal(some_signal, c). Chances are high that this signal is
supposed to be emitted on the client object 'c' instead of the underlying client
class.
This applies to awful.rules' usage of this signal.

Before commit 1b2826 in lgi, the get_rgba() function on cairo SolidPatterns was
specified like this:
get_rgba = { ret = cairo.Status,
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' } },
The above commit fixed this (without saying so) and the code became:
get_rgba = { ret = cairo.Status,
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' } },
The prototype for the corresponding cairo function is:
cairo_public cairo_status_t
cairo_pattern_get_rgba (cairo_pattern_t *pattern,
double *red, double *green,
double *blue, double *alpha);
As you see, this functions gets four double* as arguments and it will save its
result via those pointers. Old versions of lgi call this function with too few
arguments and this will cause a segmentation fault when cairo dereferences an
invalid pointer.

If a client gets moved to a screen without any selected tags, that client
disappears and it is non-trivial to get it back. Since this is unexpected and
annoying, make movetoscreen do nothing if the target screen has no tags
selected.

This allows to apply properties and callbacks to a client like
awful.rules.apply would do, without the matching part.
This is useful with the new startup notifications, and lets you apply
the same properties and callbacks from e.g. a manage signal handler.
If a drawable has an opaque background, we don't need pseudo transparency and
thus its content don't change when it is moved. However, when we need pseudo
transparency, then we have to redraw the drawable to apply the new background.
Previously we just always did the redraw. This commit adds a helper function
gears.color.create_opaque_pattern() that analyzes a cairo pattern for
transparency. We use this new function to only redraw-on-move when there is
actual pseudo transparency in effect. Otherwise, this redraw can be skipped.

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)
