This function checks if a given cairo context has an empty clip. It was
written with the assumption that cairo_clip_extents() produces the x, y,
width, height of the clip extents. However, that function actually
produces x1, y1, x2, y2, where (x1, y1) and (x2, y2) are the corners of
the rectangles.
Due to the way the function is written, it will return non-zero numbers
when there is a translation (cr:translate()). Thus, this function worked
basically never.
Fix this by checking if both points have the same X- or Y-coordinate.

With draw_empty=false, :fit() can return 0,0. Then, when :layout() is
called, it will compute negative widths and heights. This can then cause
lots of problems later on.
Avoid this by having :layout() return nothing instead of producing
negative sizes.

This commit also fixes a large number of issues found while

- Add examples for the apidoc
It makes some code easier to write. It is mostly useful when the margins
are exposed through another widget. In that case it avoids having to
proxy 5 different property or re-invent the wheel there.
Previously, the border "support" was limited to shapes and would not
move the content by the offset of the border. Borders are now better
supported and thus renamed from `shape_border_width` to `border_width.
In the end, shrinking the widget by the border size is too common to
ignore. It should have been the default all along, just like the clip.
* Fixed input_passthrough property not being set
In the table of properties supplied to the `wibox` function, you couldn't set the `input_passthrough` property. You could only set it after the wibox was created like this: `my_shlick_wibox.input_passthrough = true`. This commit fixes that and now you can set it in both ways.
Commit ba75da7976 worked around a bug in LGI. However, it did so by
just dropping the code that set the foreground color. Instead, it should
have changed the code so that cr:set_source() is only called if the
background container has a foreground color configured instead of "just
always".

cairo_get_source() is not bound correctly, leading to use-after-free

Work around this by preserving the current source in a different way.
Instead of using cairo_get_source() and later cairo_set_source(), this
commit wraps everything that changes the current source between
cairo_save() and cairo_restore(). Thus, cairo saves the current source
for us without us having to grab an explicit reference.

Previously, the background container "just" used the shape and drew a
line around it. This means that half the line will be inside of the
shape and half of it will be outside. Thus, this hides the actual shape
that is used.
This commit changes that so that the line is added outside of the shape.
It does this via some tricks:
- In :before_draw_children(), :push_group() is used to redirect drawing
of the child widget to a temporary surface.
- In :after_draw_children(), the border is added to this group.
+ For this, another temporary surface is created. It will be used as a
mask.
+ The inside of the shape on this mask is cleared, everything else is
filled. Thus, the mask now contains everything "not content".
+ Everything inside the mask is filled with the background color.
- Also in :after_draw_children(), the group is drawn to the actual
target surface.
+ Again, this needs a mask.
+ This time, we draw the shape to the mask with twice the border width.
Thus, half of this line will be outside of the shape.
+ Then, the shape itself is also filled so that the mask contains the
shape and the border.
+ This mask is then used to copy the right parts of the temporary
surface were the child widget and border was drawn to the actual
target surface that will be visible on screen.
This approach has some upsides. Because we no longer have "half the
border" above content, colors with some transparency work fine for the
border. Also, this should avoid issues with anti-aliasing, because e.g.
the border is not just drawn with the border width, but also further out
to everything else so that the background cannot "bleed through".

Before this commit, it was added by `wibox.widget.base` if
`:setup()` is used. However it doesn't work for the `awful.popup`
because of the extra indirection.
This commit stops the monkey-patching and make sure the function
always exists. This doesn't prevent it from not working and in
the long run this should still be moved into the hierarchy.
However for now it makes the situation a lot more consistent and is a
quick band-aid without too much controversy.
Mitigate #2181
It is not possible to distribute 100px to three widgets equally. The
current version of wibox.layout.flex tries to do that anyway, by giving
each widget 33px and leaving one pixel outside of any widget. Thus, if
the widgets e.g. have a common background, this leads to a one pixel gap
in the background.
This patch changes the flex layout so that the extra pixel is assigned
to some widget instead. It does so by basically keeping a sum of
space_per_item for the widgets that was assigned so far. This sum is
rounded and when this leads to rounding, the corresponding child widget
gets an extra pixel.
More precisely, this tracks a pos as before. Widgets get their position
still assigned based on rounding pos. However, this now also remembers
this rounded position for the next iteration of the loop. This allows to
assign the size of widgets based on the difference between the current
and last rounded position.

also contains the actual format string so that all the information is

Since beautiful.xresources.get_dpi(s) allows nil as argument to query

Once upon a time, beautiful.xresources.get_dpi was added to query
Xft.dpi. That made sense since this queried an xresources property. Over
time, other, non-xresources-based ways to query DPI were added to this
function. Now, it makes no more sense to have this function here.
Also, recently it became possible to add new properties to C objects
from Lua code. Thus, we no longer need to have a get_dpi() function
somewhere, but can add s.dpi directly.
Thus, this commit adds s.dpi and makes everything use it. No functional
changes are intended.

When doing w.shape_bounding = foo on a wibox, the code would first read
shape_bounding from the underlying drawin. This would create a
(possibly) huge cairo image surface that just waits to be collected by
the garbage collector, resulting in increased memory usage.
Fix this by checking the force_forward table first. This tables contains
the names of shape properties. Thus, the evaluation of this statement

This commit changes the systray widget, wibox.drawable and the C code to
fix the following bug: When the systray widget is removed from a
drawable without being moved somewhere else, the systray stayed visible.
This was because the systray is not drawn by awesome, but only placed.
When the widget is no longer "drawn", it stays wherever it was placed
last.
This change works by detecting the situation when the systray is
removed. Then, the C code is specifically told to remove the systray
window from the drawable.
Note that this is only a partial fix. This change works correctly when
the widget is removed completely, because it is no longer placed by its
parent widget. However, for example, when you do
wibox.widget.systray().visible = false, the effect is just that the
systray widget gets size 0x0. This is not really visible, but as far as
this change is concerned, the widget is still part of the drawable.

Up to now, a drawable always figured out the screen that it is on by
looking at its position. This causes memleak-like problems with wibars:
A wibar has a screen assigned, but its underlying drawable will end up
referring to another screen. Via this, we were managing to build a long
reference chain of screens and drawable that meant that none of the fake
screens that our test suite added could be garbage collected.
To fix this, add wibox.drawable._force_screen(s). After this function is
called, the normal screen detection based on the position is skipped and
instead the given screen is always used. This breaks the above reference
chain and things become garbage-collectable.
Also, this chains the drawable to the life time of the screen: When the
screen becomes invalid (.valid == false), the drawable will stop
redrawing.

Previously, the API to set the data that should be displayed was
:set_data(t) where t is a table. This table has the labels to use as its
keys and the numbers as its values. With this API, it was not possible
to influence the order in which the "pie pieces" were drawn.
This commit adds and uses a new API called :set_data_list(t). Here, t is
a table with integer keys and tables as values, thus one can iterate
over this with ipairs() and the order is well-defined. The tables used
as values contain the label as their first entry and the number as their
second entry.

Instead of matrix_to_device and matrix_to_parent, this now provides the
full hierarchy instance managing the current widget.
In addition to x, y, width and height (which are an over-approximation
of the widget's extents on the drawable), this now also provides
widget_width and widget_height in the widget's local coordinate system.
These last two values are exact.
For example, the tooltip needs x/y/width/height while a widget that
wants to figure out which point on it was hit with a mouse press will
need widget_width and widget_height (together with the position argument
that is passed in with mouse::press).
I don't know how to document the return type of this function properly.

enough.

LGI does not protect against use-after-free issues that can occur due to
using an object after finalisation. This manifests itself as occasional
crashes on Travis in cairo_region_union_rectangle() (AFAIK no one ran
into this issue in real-world usage).
Since visible drawables are always strongly reachable, the issue can
only occur with invisible drawables. The previous commit made sure that
those are fully repainted when they become visible, so we can just
ignore redraws for those and fix the crash issue.

Instead of tracking all drawables that are alive, the code now only
tracks visible drawables. When a drawable is made visible it is
completely repainted. This should not cause a difference when a wibox is
initially made visible, because it has to be redrawn anyway. However,
this introduces a full repaint when a wibox is hidden and then made
visible again.
Thanks to this change, we can stop using weak tables. Visible drawables
cannot be collected and so we can keep a strong reference to them. This
allows us to get rid of the weak tables which solves various problems
involving finalizers and using objects after finalisation.

This restore a feature that was available in Awesome 2.1-3.2.
The reason margin is implemented rather than use a container is to
be able to make the background smaller than the bar.
The current progressbar code dates from a time when Awesome had
a very limited drawing API. This commit first re-write the
algorithm to remove the workaround used to draw the border using
full rectangles only. It then add support for outer and inner
shapes with their respective border settings.
This commit also add clip support. This is enabled by default, but
could be disabled to have the bar taller than the background.
Twice now we had problems with the garbage collector which caused signals
established via weak_connect_signal() not to be disconnected when we wanted them
to be disconnected. The effect was that we tried to redraw a drawable after it
was garbage collected which caused errors.
Instead of playing whack-a-mole with all the various ways that might make us
redraw a drawable after GC, let's just fix all of these issues by explicitly
checking for this case and turning it into a no-op.

The previous commit made wibox.drawable turn a "normal redraw" into a complete
repaint when it was moved to another screen. However, nothing happened until
that normal redraw.
This commit triggers a normal redraw when we are (possibly) moved to another
screen. More precise, this means that whenever a screen appears, disappears or
changes its geometry and when the drawable is moved, we trigger a normal redraw.
This redraw will likely do nothing, because no relayout is pending and no part
of the surface needs a redraw, so it is cheap.
However, if the drawable really ends up on another screen, then the code from
the previous commits makes us do a full relayout and redraw.
This commit likely fixes the current instability of test-screen-changes.lua. See
https://github.com/awesomeWM/awesome/issues/982#issuecomment-231712056.
As explained there, the test fails because the fake screen that it created is
still referenced, so cannot be garbage collected, but the test doesn't succeed
unless the screen is garbage collected. So something is still referencing the
screen that was removed. This something can be a client's titlebar, because the
underlying drawable still has a context member referring to the old screen.
This commit should fix that problem, because we now trigger a redraw which will
compute a new context and thus the reference to the old screen is released.
