During build svg images of the calendar widget are generated, which

By honouring the environment variable SOURCE_DATE_EPOCH, which is

This still runs all the tests in the configure phase, since the tests
report back what output file (png/svg/none) will be generated.. :/
This could be improved by having this table in CMakeLists directly, or
by having a callback into the tests that only reports back that
information. The latter would still execute all the tests (via a Lua
process).

This adds a C program which tests if the window manager handles
gravities correctly. This program is loosely based on metacity's
test-gravity.c, but completely rewritten and this version does automatic
tests instead of allowing the user to perform testing by hand.
By having this as a self-contained C program, it is possible to compare
awesome's behaviour with the behaviour of other WMs.
In my testing, only metacity and awesome pass this test. This is not
that much of a big surprise since awesome was fixed in

metacity's test-gravity.c. However, I am surprised that e.g. Fluxbox

There are some cases where a client's floating state "silently" changes.
For example, a fullscreen client will be considered floating. However,
even though c.floating changes its value in this case, we did not emit
the property::floating signal.
Fix this by explicitly tracking the "implicitly floating" state. When
some property that influences this "implicitly floating" state changes,
we update it and if a client which was not explicitly assigned a
floating state observes a change in this value, property::floating is
emitted.
This was tested by running a terminal and two xeyes in a tag with a
tiling layout where awful.ewmh was patched so that clients do not change
their geometry when fullscreening or maximizing. It was observable that
after this patch e.g. the titlebar and the tasklist update to show the
floating state of the client which became implicitly floating due to
being maximized.

For a while now we had our code coverage tools tell us that the coverage
for one line of code fluctuated. Sometimes it was being executed and
other times it was not. This is useless noise.
I think what is happening here is that the coverage depends on the order
of iteration over a table. Either the tooltip that is being created was
first made visible and then it text changed, or things happened in the
opposite order.
Fix this by doing this by explicitly changing the tooltip's text while
it is surely visible.

tests/run.sh waits for awesome to exit via tail's "--pid" option. This

When the keyboard layout is modified via xmodmap, each single "change"
(line of input to xmodmap) causes an "the keyboard configuration
changed"-event to be sent. Awesome reacted to each of these events by
reloading the keyboard layout. Thus, awesome reloaded the keyboard
layout a lot and appeared to freeze.
Fix this by asynchronously update the keyboard state: When such an event
comes in, instead of reloading things immediately, we set a flag which
makes us update the state at the end of the main loop iteration. This
means that many events still cause only a single (or at least few)
re-quering of the layout. Thus, a lot of time is saved.
This commit removes the argument to the (undocumented!) signal
xkb::group_changed. Previously, the argument was the active group
number. Since this argument was unused and I'm lazy, I just removed it.
The alternative would be that it might be visible to Lua that some "the
active group changed"-events are dropped.

This commit add an option to shim the whole wibox module when

In theory, most of that code is already covered by the

This makes the coverage builds about twice as fast. This is
necessary because there is a large number of timeouts due to
limited resources on the Travis build system.
And stop listening to property::geometry, it's no longer needed.

X11 does not allow to resize a window to size 0x0. Also, there are some
possibilities of integer overflows in our case. We tried to handle this
already, but there was a loop-hole: If the too-small-value is only

Fix this by applying size hints before checking if the resulting size is

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

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.

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

The default config had tables like mywibox and mywibox[s] was the wibox
that is visible on screen s. When a screen is removed, nothing cleans up
these tables and so the screen and the wibox could not be garbage
collected. The same applies to the layoutbox, taglist etc.
This commit removes the global mywibox table and instead saves it as a
property on the screen. This way, the screen is not explicitly
referenced and when it is removed, the screen, its wibox and all of its
widgets become unreachable and can be garbage collected.

The new client is hopefully faster. Why, you ask?
Instead of spawning a new Lua process each time a test asks for a new window,
there is a "daemon process" which gets commands to open new windows from its
standard input. That way, Lua doesn't have to load LGI all the time and lots of
pointless work is skipped. The daemon process exits when its stdin is closed and
thus should automatically exit when awesome exits.

Before this commit: When we are GC'ing an object, we clear its metatable, since
otherwise crashes could occur in various places. This means that if someone
tries to use such an object, they get an unhelpful error message like "attempt
to index userdata object" and they don't understand what the problem is. Also,
this means that foo.valid does not actually work after GC.
This commit changes this behaviour. Instead of setting an empty metatable, we
now create a metatable with an __index and __newindex method. These metamethods
produce better error messages that they sat the underlying object was already
garbage collected. Better yet, the __index metamethod makes foo.valid be false
instead of causing an error, so that the existing machinery for detecting
invalid objects continues to work.
This commit also adds a functional test that verifies this behaviour.

This commit make sure of that by disabling the default normal source
