Part of the reason for adding headless support in vmon is to
facilitate embedded use cases. These are often incompatible with
anti-tivoization aspects of gplv3.
I am the copyright holder of all this stuff so it's entirely fine
to switch to gplv2. Phil Freeman contributed one trivial patch
(4183fbd), regardless I checked if he had any objections to the
gplv2 switch and he had none.
So here we go, gplv2 all the things.

Just expanding the heuristic to everything >= fullscreen instead
of precisely fullscreen. The specific impetus for this was
fullscreen games, but from a security standpoint it makes sense
to manage everything larger as well.
|
|
Now vwm ignores override_redirect for fullscreen windows.
|
|
Preparatory commit for applying a heuristic to honoring
override_redirect.
The X11 specification more or less requires honoring this window
flag, but it's really a disaster to blindly do so.
This function will be used to evaluate override_redirect wherever
it's currently being directly used to determine wether a window
should be managed or not.
As-implemented it only ignores override_redirect when the window
dimensions match its screen dimensions (fullscreen windows). In
the future this might get loosened up a bit to encompass windows
covering more than something unexpectedly large for a
tooltip/popup, like 50% of the screen, since valid
override_redirect uses should arguably be limited to small
windows.

Currently only vmon wires this up to --name, but vwm could get
the window title of the window being overlayed and pass that in
if set...

This is unfortunately a bit of a large commit, but it's at least
pretty much all on-topic for the generalized "contexts" feature.
Rather than waste time trying to split this further into smaller
commits, I'm just landing it as-is, now that I've lived with the
interaction model long enough to not completely hate it.
I fully expect to revisit this in the future. One TODO item in
particular I'd like to note is "sending" windows to contexts
always creates a new virtual desktop for the sent window in the
destination context. What should really happen is the
destination context should be checked for an empty desktop, and a
new desktop created only when there isn't an empty one to be
reused for receiving the sent window. Note this only affects
non-migrate sends, as migrates (modified by Shift) explicitly use
the existing focused desktop at the destination context.
See the README for more information on how contexts work and
what's different about the interaction model. It's fairly
minimal, most of what you already know how to do should keep
working as-is. The only oddity would be Mos1-s no longer
"shelves" windows, it's now a modifier to turn "migrates" into
"sends", and by itself is a noop now.
Colors used for contexts haven't been refined and are enumerated
in src/context_colors.def.

Some programs call XSetInputFocus(), so we should select
FocusChangeEvent and handle FocusIn events, calling vwm_win_set_focus()
when appropriate.
It's rare, but SDL2 programs in particular seem to do this and vwm gets
in a pretty annoying state when it does occur. This change should
improve the situation.

vmon introduces a non-overlay usage, monitors is correct but ambiguous,
graphs is also amiguous, charts is short and distinctive.
renaming of the files comes in a separate, future commit.

In the course of applying the new style over the rest of the code I
decided it's obnoxiouos and prefer the old way of indenting the cases
one level from the switch. I know it wastes horizontal space and can
see the value of flattening the cases with the switch, but once you
start having variables at the start of the switch body, and blocked
cases, it just starts becoming quite unattractive without the indentation.

This member reflects if the window is mapped from the client's perspective,
not necessarily if the window is currently mapped (since vwm maps and unmaps
windows the client has mapped in the course of providing virtual desktops)
Changing the name for better clarity, since it's a bit ambiguous as-is.
|

It's far too obnoxious to use without this enabled.
Some spurious cleanups in the surrounding code landed here as well.
|
|
No functional changes here.

I'm no longer fond of combining one-line conditional statements on
the same line as their conditional expression.

- Move vmon_proc_t under vwm_overlay_t.
- Privatize vwm_overlay_t.
- Update xwindow.c to dynamically create and destroy overlays.
- Cease supplying vwm_t to vwm_overlays_create(), now just
pass in the bare vwm_xserver_t.
- Update all vwm_overlay_* functions to operate on vwm_overlays_t and
vwm_overlay_t. Only vwm_overlays_create() receives the xserver,
which it then embeds within the returned vwm_overlay_t.
- Eliminate _xwin_ flavors of overlay functions, largely mechanical
rename eliminating the _xwin_ from the names during the previous
pass of switching from vwm_t & vwm_xwindow_t to vwm_overlays_t &
vwm_overlay_t parameters.
- Change vwm_overlay_compose() to store damage in supplied pointer,
the caller is expected to make use of the damage information now
because the overlay code doesn't know about the window its coordinate
space.

Eliminate some initialization cruft.

In preparation for vwm_overlays_* encapsulation of overlay global state
and general cleanup therein.

Long overdue house cleaning.
The addition of compositing/monitoring overlays in vwm3 pushed vwm well past
what is a reasonable size for a simple thousand line file. This is a first
step towards restoring sanity in the code, but no behavioral differences are
intended, this is mostly just shuffling around and organizing code.
I expect some performance regressions initially, follow-on commits will make
more improvements to that end as the dust settles.
