To happen, both of these races have to be lost by client3
* client2 have to take more time to `:kill()` than client3 take
to be spawned.
* client4 have to start faster than client3
It is very unlikely to happen on normal systems, but on server it
happens. Some factor that may or may not be involved
* The scheduler assigned client2 on a very busy CPU and client 3
on a CPU still busy while some other CPUs are idle
* Linux is bad at scheduling hyper-threading
* The system is NUMA and the memory bandwidth is lacking on a core
* There is some "Z" memory compression or drive based swap
* Extreme bad luck
Fix#2424
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).
The commit also re-work the build target so if the file are deleted,
then they are created again. Using `file(COPY ...)` and
`file(MAKE_DIRECTORY ...)` as done previously caused some file to be out
of date or not being regenerated at all.
This commit also fixes some broken target that depended on `file(` and
`configure_file` CMake command not being part of any target.
Fix#2342
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.
