Stein c2b748e793 Remove dmenumon variable
Reasoning: Since 2011 dmenu has been capable of working out which
monitor currently has focus in a Xinerama setup, making the use
of the -m flag more or less redundant.

This is easily demonstrated by using dmenu in any other window
manager.

There used to be a nodmenu patch that provided these changes:
https://git.suckless.org/sites/commit/ed68e3629de4ef2ca2d3f8893a79fb570b4c0cbc.html

but this was removed on the basis that it was very easy to work
out and apply manually if needed.

The proposal here is to remove this dependency from dwm. The
mechanism of the dmenumon variable could be provided via a patch
if need be.

The edge case scenario that dmenu does not handle on its own, and
the effect of removing this mechanism, is that if the user trigger
focusmon via keybindings to change focus to another monitor that
has no clients, then dmenu will open on the monitor containing the
window with input focus (or the monitor with the mouse cursor if
no windows have input focus).

If this edge case is important to cover then this can be addressed
by setting input focus to selmon->barwin in the focus function if
there is no client to give focus to (rather than giving focus back
to the root window).

Stein 5799dd1fca Remove blw variable in favour of calculating the value when needed
The purpose and reasoning behind the bar layout width (blw) variable
in dwm the way it is today may not be immediately obvious.

The use of the variable makes more sense when looking at commit
2ce37bc from 2009 where blw was initialised in the setup function
and it represented the maximum of all available layout symbols.

	for(blw = i = 0; LENGTH(layouts) > 1 && i < LENGTH(layouts); i++) {
		w = TEXTW(layouts[i].symbol);
		blw = MAX(blw, w);
	}

As such the layout symbol back then was fixed in size and both drawbar
and buttonpress depended on this variable.

The the way the blw variable is set today in drawbar means that it
merely caches the size of the layout symbol for the last bar drawn.

While unlikely to happen in practice it is possible that the last bar
drawn is not that of the currently selected monitor, which can result
in misaligned button clicks if there is a difference in layout symbol
width between monitors.

Stein 44adafe006 Make floating windows spawn within the monitor's window area
This is a follow-up on this thread:
https://lists.suckless.org/hackers/2208/18462.html

The orginal code had constraints such that if a window's starting
attributes (position and size) were to place the window outside of
the edges of the monitor, then the window would be moved into view
at the closest monitor edge.

There was an exception to this where if a top bar is used then the
window should not obscure the bar if present, which meant to place
the window within the window area instead.

The proposed change here makes it the general rule that floating
windows should spawn within the window area rather than within the
monitor area. This makes it simple and consistent with no
exceptions and it makes the intention of the code clear.

This has the benefit of making the behaviour consistent regardless
of whether the user is using a top bar or a bottom bar.

Additionally this will have an effect on patches that modify the
size of the window area. For example if the insets patch is used to
reserve space on the left hand side of the monitor for a dock or a
vertical bar then new floating clients will not obscure that area.

Stein a859676ead Simplify client y-offset correction
The reasoning behind the original line may be lost to time as
it does not make much sense checking the position on the x-axis
to determine how to position the client on the y-axis.

In the context of multi-monitor setups the monitor y position
(m->my) may be greater than 0 (say 500), in which case the window
could be placed out of view if:
   - the window attributes have a 0 value for the y position and
   - we end up using the y position of bh (e.g. 22)

If the aim is to avoid a new floating client covering the bar then
restricting y position to be at least that of the window area
(m->wy) should cover the two cases of using a top bar and using a
bottom bar.

NRK 5e76e7e21d code-style: simplify some checks
main change here is making the `zoom()` logic saner. the rest of the
changes are just small stuff which accumulated on my local branch.

pop() must not be called with NULL. and `zoom()` achieves this, but in a
very (unnecessarily) complicated way:

if c == NULL then nexttiled() will return NULL as well, so we enter this
branch:

	if (c == nexttiled(selmon->clients))

in here the !c check fails and the function returns before calling pop()

		if (!c || !(c = nexttiled(c->next)))
			return;

however, none of this was needed. we can simply return early if c was NULL.
Also `c` is set to `selmon->sel` so we can use `c` in the first check
instead which makes things shorter.

Stein 786f6e2a6f unmanage: stop listening for events for unmanaged windows
This is in particular to avoid flickering in dwm (and high CPU usage)
when hovering the mouse over a tabbed window that was previously
managed by dwm.

Consider the following two scenarios:

1)

We start tabbed (window 0xc000003), tabbed is managed by the
window manager.
We start st being embedded into tabbed.

$ st -w 0xc000003

What happens here is that:
   - tabbed gets a MapRequest for the st window
   - tabbed reparents the st window
   - tabbed will receive X events for the window

The window manager will have no awareness of the st window and the
X server will not send X events to the window manager relating to
the st window.

There is no flickering or any other issues relating to focus.

2)

We start tabbed (window 0xc000003), tabbed is managed by the
window manager.
We start st as normal (window 0xd400005).

What happens here is that:
   - the window manager gets a MapRequest for the st window
   - dwm manages the st window as a normal client
   - dwm will receive X events for the window

Now we use xdotool to trigger a reparenting of the st window into
tabbed.

$ xdotool windowreparent 0xd400005 0xc000003

What happens here is that:
   - tabbed gets a MapRequest for the st window
   - tabbed reparents the st window
   - the window manager gets an UnmapNotify
   - the window manager no longer manages the st window
   - both the window manager and tabbed will receive X events
     for the st window

In dwm move the mouse cursor over the tabbed window.

What happens now is that:
   - dwm will receive a FocusIn event for the tabbed window
   - dwm will set input focus for the tabbed window
   - tabbed will receive a FocusIn event for the main window
   - tabbed will give focus to the window on the currently selected
     tab
   - which again triggers a FocusIn event which dwm receives
   - dwm determines that the window that the FocusIn event is for
     (0xd400005) is not the currently selected client (tabbed)
   - dwm sets input focus for the tabbed window
   - this causes an infinite loop as long as the mouse cursor hovers
     the tabbed window, resulting in flickering and high CPU usage

The fix here is to tell the X server that we are no longer interested
in receiving events for this window when the window manager stops
managing the window.

Chris Down 8b48e30973 manage: Make sure c->isfixed is applied before floating checks
Commit 8806b6e237 ("manage: propertynotify: Reduce cost of unused size
hints") mistakenly removed an early size hints update that's needed to
populate c->isfixed for floating checks at manage() time. This resulted
in fixed (size hint min dimensions == max dimensions) subset of windows
not floating when they should.

Chris Down 8806b6e237 manage: propertynotify: Reduce cost of unused size hints
This patch defers all size hint calculations until they are actually
needed, drastically reducing the number of calls to updatesizehints(),
which can be expensive when called repeatedly (as it currently is during
resizes).

In my unscientific testing this reduces calls to updatesizehints() by
over 90% during a typical work session. There are no functional changes
for users other than an increase in responsiveness after resizes and
a reduction in CPU time.

In slower environments or X servers, this patch also offers an
improvement in responsiveness that is often tangible after resizing a
client that changes hints during resizes.

There are two main motivations to defer this work to the time of hint
application:

1. Some clients, especially terminals using incremental size hints,
   resend XA_WM_NORMAL_HINTS events on resize to avoid fighting with the
   WM or mouse resizing. For example, some terminals like urxvt clear
   PBaseSize and PResizeInc during XResizeWindow and restore them
   afterwards.

   For this reason, after the resize is concluded, we typically receive
   a backlogged XA_WM_NORMAL_HINTS message for each update period with
   movement, which is useless. In some cases one may get hundreds or
   thousands of XA_WM_NORMAL_HINTS messages on large resizes, and
   currently all of these result in a separate updatesizehints() call,
   of which all but the final one are immediately outdated.

   (We can't just blindly discard these messages during resizes like we
   do for EnterNotify, because some of them might actually be for other
   windows, and may not be XA_WM_NORMAL_HINTS events.)

2. For users which use resizehints=0 most of these updates are unused
   anyway -- in the normal case where the client is not floating these
   values won't be used, so there's no need to calculate them up front.

A synthetic test using the mouse to resize a floating terminal window
from roughly 256x256 to 1024x1024 and back again shows that the number
of calls to updatesizehints() goes from over 500 before this patch (one
for each update interval with movement) to 2 after this patch (one for
each hint application), with no change in user visible behaviour.

This also reduces the delay before dwm is ready to process new events
again after a large resize on such a client, as it avoids the thundering
herd of updatesizehints() calls when hundreds of backlogged
XA_WM_NORMAL_HINTS messages appear at once after a resize is finished.

Miles Alan bece862a0f manage: For isfloating/oldstate check/set, ensure trans client actually exists
In certain instances trans may be set to a window that doesn't actually
map to a client via wintoclient; in this case it doesn't make sense
to set isfloating/oldstate since trans is essentially invalid in that
case / correlates to the above condition check where trans is set /
XGetTransientForHint is called.

Chris Down 8657affa2a drawbar: Don't expend effort drawing bar if it is occluded
I noticed that a non-trivial amount of dwm's work on my machine was from
drw_text, which seemed weird, because I have the bar disabled and we
only use drw_text as part of bar drawing.

Looking more closely, I realised that while we use m->showbar when
updating the monitor bar margins, but don't skip actually drawing the
bar if it is hidden. This patch skips drawing it entirely if that is the
case.

On my machine, this takes 10% of dwm's on-CPU time, primarily from
restack() and focus().

When the bar is toggled on again, the X server will generate an Expose
event, and we'll redraw the bar as normal as part of expose().

Chris Down 67d76bdc68 Do not allow focus to drift from fullscreen client via focusstack()
It generally doesn't make much sense to allow focusstack() to navigate
away from the selected fullscreen client, as you can't even see which
client you're selecting behind it.

I have had this up for a while on the wiki as a separate patch[0], but
it seems reasonable to avoid this behaviour in dwm mainline, since I'm
struggling to think of any reason to navigate away from a fullscreen
client other than a mistake.

bakkeby f09418bbb6 dwm crashes when opening 50+ clients (tile layout)
Many users new to dwm find themselves caught out by being kicked out to the login manager (dwm crashing) when they open 50+ clients for demonstration purposes. The number of clients reported varies depending on the resolution of the monitor.

The cause of this is due to how the default tile layout calculates the height of the next client based on the position of the previous client. Because clients have a minimum size the (ty) position can exceed that of the window height, resulting in (m->wh - ty) becoming negative. The negative height stored as an unsigned int results in a very large height ultimately resulting in dwm crashing.

This patch adds safeguards to prevent the ty and my positions from exceeding that of the window height.

Chris Down a8e9513783 setmfact: Unify bounds for compile-time and runtime mfact
There are two places that mfact can be set:

- In the mfact global, which is defined at compile time and passed
  into m->mfact during monitor setup. No bounds checks are performed,
  but the comment alongside it says that valid values are [0.05..0.95]:

      static const float mfact = 0.55; /* factor of master area size [0.05..0.95] */

- By setmfact, which adjusts m->mfact at runtime. It also does some
  minimum and maximum bounds checks, allowing [0.1..0.9]. Values outside
  of that range are ignored, and mfact is not adjusted.

These different thresholds mean that one cannot setmfact 0.95 or 0.05,
despite the comment above that lists the legal range for mfact.

Clarify this by enforcing the same bounds in setmfact at runtime as
those listed for mfact at compile time.
