When calling join with e.g. arguments (nil, {"a"}), then everything past
the nil was ignored, because the code internally used ipairs() to
iterate over the arguments and this stops at the first nil it
encounters.
Fix this by using select() to iterate over the arguments.
This also adds a unit test for this problem.

In the earlier revision of the keygrabber PR, there was a `release_key`
and it was suggested to rename it `stop_key`. However its sibling
`release_event` wasn't, so it is now confusing.
The commit adds a mild deprecation codepath to avoid breaking configs
based on git-master. However it isn't a "long term" deprecation notice
and the code can probably be removed in 5.0 without further delay.
Previously, the layout list was global. However it wasn't covering all
possible use cases and make using `awful.widget.layoutlist` hard since
a layout could be excluded from the `awful.layout.layouts` but still
used for a tag (by setting it explicitly).
Until now there wasn't much documentation available about how to use
these properties. With the new work on `awful.spawn` that rely more and
more on `awful.rules` integration, it is worth fixing.
This commit add a new documentation section and a future commit will
aggregate them to generate an index.
When mangling notifications via naughty.config.notify_callback it is
advised (1) to return nil to reject a notification. The underlaying dbus
library tries to access a field of that notification table and fails.

The toggle/show/hide function were incompatible with the current
`rc.lua` is `titlebars_enabled` was removed from the rules because
they were never created. This has always been the case but the
introduction os `request::titlebars` in Awesome 4.0 allows to solve
this longstanding issue. However until now it didn't.
Fix#2419
If the history file (or its parents) can't be created, running a command
will fail entirely. Since saving command history is not an integral part
of running a command, it would be nicer if it carried on, just without
saving history. This is what shells usually do.
This patch removes assertions in the history saving function and
instead adds an early return, so if the history isn't saved the command
invocation simply carries on.

This commit adds a way to leverage the xproperty and startup_id APIs
to persist an execution token across restarts. It allows to use
`awful.rules` on clients that were executed by a previous Awesome
instance.
The main limitations of these methods is the lack of entropy used to
build the token. If the command is the same in multiple
`awful.spawn.once`, then it will not work as expected. To mitigate this
issue, the system try to concatenate the `awful.rules` table after the
command and hash the resulting string. Given rules are a table, it can
have loops and/or issues with keys ordering. The hash function sort and
limite recursion to prevent a stack overflow. Another issue is the
unreliability of startup notifications.
`pairs` order isn't defined and `{...}` will always be ordered.
There is no reason to have random behavior where it can be
predicted at no additional cost.
The awful.placement.no_offscreen function did not work properly when
composed with other placement functions; in particular, the default
configuration (awful.placement.no_overlap+awful.placement.no_offscreen)
was broken. The compose function sets args.pretend=true and puts the
result of the previous placement function into args.override_geometry
before calling the next placement function, but no_offscreen did not use
args.override_geometry, therefore the result of the previous placement
function was discarded.
All other placement functions use `geometry_common(c, args)` to get the
current client geometry; `area_common(c)` should be used only when
getting geometry of other clients.
This change also fixes the problem with margin handling (adding margins
should not affect the window size, only the window position should
change); the test output which was adjusted in commit 0275d3537d
is adjusted again to account for this change.

The awful.placement.no_overlap function was adding the window border
width to the client width and height (this is performed in
area_common(), which is called by geometry_common()), but did not
reverse this operation by calling remove_border() before returning the
final geometry; because of this, using no_overlap resulted in increasing
the window width and height by 2*border_width.
The bug was probably introduced in commit ebcc19844e (before
that commit no_overlap changed the window position directly instead of
relying on the new placement infrastructure), but was not noticed
because of other problems (e.g., in the default configuration the result
of no_overlap was overridden by the buggy no_offscreen).

The current taglist/tasklist allow filter function to remove elements
from the list. However they don't allow sorting or additional entries
to be listed.
This commit introduced such a concept. It will later be used by the
layoutlist where it becomes more relevant since layouts are used created
"objects".
This property is based on Motif WM hints and checks if the client
requests that it is not decorated with a titlebar.

When an icon is sent over dbus, we turn this into a cairo ImageSurface.
This is done by turning the actual icon data into a string and using
cairo.ImageSurface.create_for_data() to create a surface for this data.
However, this function only creates an ImageSurface that refers to this
data. It does not copy the data. Thus, when the Lua GC later frees the
string, we have a cairo surface that refers to already-freed data.
Fix this by duplicating the cairo surface, which makes cairo create a
copy of the data. Then, we finish the original surface. While doing
this, the string is kept alive in a local variable.

When a tag is specified by name, awful.rules only searched for the tag
on the client's screen. This commit extends the search to all screens,
but only if no specific screen was specified for the new client by some
rule.

The typo was introduced in commit a1941efc9.
Its effect should be minimal: :item_enter() itself does not care about
the 'mouse' option, but it forwards to :exec(). Here, an action is
invoked either if it was not caused by the mouse, or if it was caused by
the mouse and either auto_expand is enabled (which is the default), or
the item-to-be-executed is actually the active item.
In other words, it is quite non-trivial to come up with a case where
this typo made a difference. But of course that's no reason to leave the
typo in.

The old keygrabber API wasn't doing what the users want from a
keygrabber module. With tons of boilerplate code, everything could
be done, but it wasn't trivial.
This commit add a default grabber function that implements the
keybinding API already used by `awful.key` and `awful.prompt`.
It also add syntax candy left and right to make the module "feel"
like a native CAPI object.
Nothing is perfect and some parts, like adding root keybindings, are not
vevy pleasing. However it fulfill its goal when it comes to make
previously non-trivial use case very easy to implement and deploy.
This code was attached to mouse::enter in `rc.lua` instead of being part
of the unified request::activate architecture.
There is currently no way to detach this focus filter because it is
generally correct.
There is currently no centralized way to manage active keybindings so
the description data case be used to fill part of that role until an
official API is added.
Layouts work with the client's geometry in "space on screen that is
assigned to this client". This means that the geometry should include
decoration (titlebar and borders) and useless gaps.
Everything else (especially the C code) works with client's geometry in
"space that the client can draw on". This means that the titlebar,
borders and the useless gaps are not included into this size.
Thus, when applying size hints, the tile layout has to convert between
these two representations. Otherwise, size hints are applied incorrectly
and to a wrong geometry.

I do not know how a GDataInputStream / GBufferedInputStream decides
about the size of its internal buffer when reading input by line, but in
issue #2288, an example where the output of date (about 30 bytes) was
read ten times per second caused ten megabytes of memory usage for this
internal buffer. Try to save some memory by explicitly shrinking the
buffer size when we are done reading from the stream.

In #2112 the way of loading category icons was changed to use
utils.lookup_icon. However this function does not look in the
categories paths where the categories icons are located, and
so the category icons are no longer being displayed.
This change makes errors messages show up in the replies, too.
Before (notice how the third command does not generate output):
$ awesome-client 'return 42' ; awesome-client 'sdfsdf' ; awesome-client 'error("foo")'
double 42
string "[string "sdfsdf"]:1: syntax error near <eof>"
After:
$ awesome-client 'return 42' ; awesome-client 'sdfsdf' ; awesome-client 'error("foo")'
double 42
string "[string "sdfsdf"]:1: syntax error near <eof>"
string "Error during execution: [string "error("foo")"]:1: foo"

For "stuff around screen's 'removed' signal", it might make sense to
temporarily set a tags screen to nil. The idea is that it will only
later be assigned to a new screen, not immediately.
However, currently a tag with screen nil causes quite some problems in
the set_screen() function. This commit works around this with a generous
amount of "wrap this in if".
