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.

The previous commit made the hierarchy do a re-layout when the context changes.
However, widgets could change their appearance depending on the context without
changing their layout. Thus, the previous commit is not enough.
This commit also makes the drawable redraw everything when the context changes.

When the context for widget changes (e.g. we are on a new different screen or
have a different DPI value), widgets might change their appearance even though
they didn't emit widget::layout_changed. Thus, update the hierarchy in these
cases.

The magnifier layout wants to ignore floating clients. Before 82342f0 this was
done by calling awful.client.floating.get(focus). If "focus" was nil, this might
have checked the floating status of a wrong client (if some other client was
focused, and the code in magnifier set focus=nil before). This issue can easily
be missed and might exist since forever. After 82342f, floating status is
checked via "focus.floating" and this now causes an "attempt to index nil value"
error instead. Much easier to notice.
Fix this by adding the missing nil check and while touching the code, merge this
with the previous "if" and correct another error (the wrong thing happened if we
had #cls=0).

A client is supposed to go to a screen when:
* It has been started using `awful.spawn` with explicit instructions [1]
* An `awful.rules` rule **or any of its callbacks** set the screen [2]
* When something handle `request::screen` and/or `request::tag` in some
custom ways. [3]
* Some clients can request a screen and mean it (like MythTV/Kodi/XBMC and
some multi-window DAW) [4]
A client is supposed to go to the focused screen when none of the above are
true [5].
Other constraints:
* The screen need to be set only once, anything will will emit
`property::screen` many time and cause side effects.
* There has to be a single entry point to the algorithm, no multiple
"manage" handler.
* Awesome internals must use the `request::` signal API and not force
their decision outside of request handlers.
* Restarting Awesome must not change the client screen
Commit 2178744 fix use case number [1] and [2]. It actually fix [4] too, but
it is an accident and I am not sure we care about [4] anyway. Use case [1]
and [2], however, are very important.
Fix#1091
The geometry storage has been moved into awful.placement. This
code was never executed as data[] was never populated.
There is some behavior that is indeed lost, but it is unlikely
someone will ever notice (it has been broken for 6 months).
The previous code attempted to handle scrren changes while
maximized. The new code organization shift this responsability
to awful.placement. However, it doesn't yet fully implement the
previous logic.
Awesome 3.5.9 accepts `_active`/`_inactive` names for `beautiful`
minimize keys (such as "titlebar_minimize_button_focus_inactive").
Some themes rely on those, meaning that when they loaded under
the current Git, the minimize button went missing. This adds a
fallback, to improve compatibility with the existing themes.
This commit remove the `awful.tag` "manage" hook. The relevant
code has been moved to ewmh.lua request::tag handler. The handler
is called either by a volontary screen change or by a forced one.
It also require the awful.rules to be executed. This is done by
default and the user would have to explicitly disable that
behavior. From now on, disabling the rules require the user to
handle tag selection.
Fixes#1028#1052
There was still a problem that caused the "old" tags to be
inserted in the wrong position when "saved" from a screen being
removed.
Also, this use a :get_tags(true) to save an uneeded sorting pass.
The index was updated on an unordered table. As the elements
order did not match the relative indices once they have been
changed, further calls to set_index produced garbage.
The default taglist didn't notice because it use screen.tags
table index instead of the tag index. A debug using
echo 'for _,t in ipairs(mouse.screen.tags) do
print("INDEX:", _, t.index, t.name) end' | awesome-client
Would have shown two or more elements with the same index. To
debug issues related to tag indices, this bash script can be
enabled:
while true; do
echo 'for _,t in ipairs(mouse.screen.tags) do
assert( _==t.index) end' | awesome-client
sleep 0.5
done
This commit add the last placement function imported from the
Radical module.
It allows to place a wibox/client next to another object. It tries
to find the best fit. It also support wibox widgets.
This is intended for tooltips and menus, but can also be used in
`awful.rules` to place the new client as close as possible to the
focused one without overlap.
This reverts commit facf676b13.
Using capi.client.focus.screen to decide which screen is focused breaks
a multiscreen setup. At least makes it extremely annoying to use.
In particular, if you have a focused client on screen 1, move the mouse
to screen 2 and launch a new client, the new client appears in screen 1,
since screen.focused reports that current focused screen is 1, not 2
because of the focused client.
Close#1035Fix#1029
The deprecation wrapper that we still have for this function didn't return
anything. However, awful.util.pread() used to return strings. This breaks
script.
Work around this by returning an empty string. That way code will still break,
but at least it should not error out.

The default config creates the same set of tags for all screens ("1" to "9"). An
awful.rules-rule with e.g. screen = 2, tag = "3" should obviously tag matching
clients with tag "3" of the second screen.
However, the implementation used the first matching tag in the list of all tags
and thus the client ended up tagged with tag "3" from screen 1. Fix this by
calling find_by_name() with the screen that the client is assigned to.
The existing implementation of awful.rules guarantees that any
"screen"-properties are applied before the code touched by this commit is run,
thus this should always work.
This commit does not add a test catching this because we are currently quite bad
at testing multi-screen scenarios and I don't want to invent the necessary
machinery right now.

Commit 0318c6132840413b1f added an image for the minimize button which was
missing before. However, only the default theme and xresources where fixed to
contain the path to the image.
This commit adds the path to all themes.
Also, minimized clients aren't visible, just as closed (=killed) clients aren't
visible. Thus, we don't need an "active" version of this image.
This commit makes us handle the image for the minimize button just like we
handle the close button: There is no difference between "active" and "inactive"
and the file path in the theme doesn't get any path suffix.

The actual bg is drawn either with fake transparency over the wallpaper (this
uses operator OVER) or for true transparency with operator SOURCE. The bgimage
should be drawn ontop of this without erasing the background and thus needs
operator OVER.
However, before this commit the bgimage was drawn in the same way as the bg and
thus inherited its SOURCE operator if a compositor is running. Fix this by
restoring the default operator (OVER) and also e.g. the default source before
drawing the bgimage.

All other shape did it. While it usually have no side effects,
as seen in #920 screenshot from @actionless, there is instances
where this produce a invalid rectangle.
If:
1) An app is open in a tag
2) A new tag is created
3) The app is closed in the first tag
4) The first tag is deleted
5) The new tag is deleted
Then this history would try to restore an inactive tag without
a screen. Bad things will then happen.
Reported on IRC. I am not sure why swap() is not enough, but the
old code removed before the mouse refactor did this, so apparently
it is necessary.
The fix has been reported to work by spyroboy on IRC, thanks!
First some reminder on how client geometries works (in X11, awesome just copied
that!):
- The position (x,y) defines where the border of the client begins
- This means that the content starts at (x+border_width,y+border_width)
- However, the size is the size of the client without border
- Thus, the client covers the rectangle from (x,y) to (x+2*bw,y+2*bw)
The client snapping code got this wrong. It only deals with rectangles and thus
for things to work as expected, the width/height have to be increased by two
times the border width. When snapping a client against other visible clients,
the geometry of the client to snap against wasn't calculated correctly.
This was apparently noticed at one point and worked around by decreasing the
position by two times the border width. While this is terribly wrong, it
actually makes things work correctly when snapping to the right or bottom edge
of a client, but breaks for the other edges.
Fix this by just calculating things correctly.
This is based on a patch from jk411.

The requirement to call add_signal() was added to catch typos. However, this
requirement became increasingly annoying with property::<name> signals and e.g.
gears.object allowing arbitrary properties to be changed.
All of this ended up in a single commit because tests/examples fails if I first
let add_signal() emit a deprecation warning.

There was already a bug, as self.active_child.visible
was used instead of self.active_child.wibox.visible
This caused some confusion that this attribute was a widget.
It wasn't.
It was set as `module` instead of `class` because ldoc was confused
set shown the methods as functions and functions as methods.
This commit set the explicit section so ldoc don't gress (wrongly)
local functions and metatable based constructors are not
documented unless an explicit @function is added.
Also add missing return values and fix formatting.
The behavior was changed during the rewrite. This was a mistake
as it was assumed (wrongly) that nobody used this function with
wiboxes other than "wibars" (awful.wibox).
Fixes#917
Since the screen removal patchset, the tags properties were
cleaned too early. This caused code connecting to "property::activated"
to be called with the tag already partially deleted. For code depending
on those properties, such as radical.impl.taglist, this caused errors.
Apparently, there is such thing as not leaking enough...
Also try to clear the widgets from mywibox. This seem to help.
Time will tell.
Fixes#914, unfixes #808
Similar systems already exist un luaobject, wibox and the declarative
widget system. This close the gap and also bring the property based
syntax to wibox and other gears.object users.
While this need to be enabled explicitly for legacy reasons, it
doesn't break the API.
Once widespread, this implementation will replace the one found
in wibox.widget.base_widget.
