wlroots implements this behavior with its key press tracking but
continues to forward the events to the compositor. Matching the wlroots
behavior here seems like the best way to avoid strange edge cases and
this is unlikely to ever be an annoying limit in practice.
Also take this oppurtunity to finally refactor away the hasMapping()
function in a way that doesn't sacrifice correctness even when hitting
this 32 key press limit.
It didn't occur to me that this is a completely valid case when a key
release event is received even though there was no press event known
to river.
(I've also just had this same crash on something else, but i don't
understand what the cause could be.)
The old eat/pass-on point of view was good when there was only the
focused client to send the key to. But where does the input method
stand? Instead, we now want to know where the key goes, treating river
and clients all equally.
Thanks to ifreund for pointing me to std.BoundedArray which simplifies
some of the logic.
Currently configure timeouts hit the "client is buggy and initiated size
change while tiled or fullscreen" code path even if the client is not in
fact buggy. This causes state to get out of sync between river and the
client, and is highly visible as the borders drawn by river no longer
align with the buffer dimensions committed by the client.
This commit fixes this by tracking acks/commits in response to
configures even after a timeout and properly integrating them with the
transaction system.
There are some cases in which a view can end up with a size/position
that places some part of it outside its output. For example, a window
with a large minimum size in a tiled layout that is placed near the
right or bottom edge of the output may extend past the output bounds.
The problem with this is that part of the view outside the output bounds
may be rendered on another output where it does not belong in a multi-
monitor setup.
To fix this, clip the surfaces of the view and the borders to the output
bounds.
Focus may not actually change here so seat.focus() may not automatically
warp the cursor. Nevertheless, a cursor warp seems to be what users
expect with `set-cursor-warp on-focus` configured, especially in
combination with focus-follows-cursor.
To see why this is needed, compare the following flows:
- user: press key 'j' with Super already pressed
- Keyboard: handle mapping, focusing next view
- Seat: send wl_keyboard.enter with keys Super and 'j'
- Keyboard: eat key 'j'
versus:
- user: press key 'j' with Super already pressed
- Keyboard: eat key 'j'
- Keyboard: handle mapping, focusing next view
- Seat: send wl_keyboard.enter with key Super.
The necessity of this was already mentioned in 1e3b8ed1; however,
without a comment in code, it was removed in 393bfb42 as superfluous.
Hopefully, the newly added comment will prevent such mistakes in the
future.
Fixes https://github.com/riverwm/river/issues/978
As noticed by leon-p, last refactorings made river send a release event
to the client even if the press event has been eaten. In addition, the
introduction of input method support means that we need to remember
*why* we've eaten the key.
Also make KeycodeSet more strict: i am not aware of any case when a
keyboard could have the same key pressed twice (specifically, keyboard
groups have this handled in wlroots), so make the behavior follow a
smaller set of possible scenarios.
It's unclear if this is technically a violation of the protocol or not,
but it makes little sense to do this and many clients in the wild crash
if wl_keyboard.enter is sent before wl_keyboard.keymap.
If our current approch without xkbcommon translation does not match any
mapping on a key event attempt to match the translated keysym as well.
This makes e.g. the keypad number keys (e.g. KP_1) work intuitively as
they may require translation with numlock active.
The reason we stopped doing this in I7c02ebcbc was due to layout where
e.g. Super+Shift+Space is translated as Space with the Shift modifier
consumed, thereby conflicting with a separate mapping for Super+Space.
This should not be a issue anymore though as we now only run a maximum
of one mapping per key event and we attemt to match mappings without
xkbcommon translation before attempting with translation.
It seems to be a bit too early to drop support for this legacy protocol.
Xwayland apparently still relies on it for hardware acceleration as do
fairly recent mesa versions still in widespread use.
When `focus-follows-cursor` is set and the cursor moves onto an output
where no views are present on the currently visible tags, focus the
output itself instead of an individual view.
This is useful e.g. when you want to spawn a terminal on your empty
monitor or switch it to a different tag. Previously such changes would
happen to the monitor on which you previous focus was, despite the
cursor being somewhere else.
wlroots will now load xcursor themes at the correct scale automatically
based on the scale of the outputs where ther cursors are displayed.
Also make the error handling a bit more robust.
Previously new keyboards would not be added to already existing
keyboard groups on (re-)connect. Only during the creation of
the groups themselves were devices added to them. This meant
that only keyboards connected during startup - before the init
is executed - would work with groups in a typical river session.
This code could allows the view to be focused and urgent at the
same time if the request to activate the view is received just after
the pending focus has been set but before the transaction completes.
This commit leverages the new wlr_scene helper to send custom feedback
per surface rather than using the same default feedback for every
surface. This should allow direct scanout to work more reliably with
multiple outputs for example.
wl_drm is a legacy interface superseded by the linux-dmabuf
protocol. All clients should migrate.
This commit drops support for the protocol which should help find
whatever problematic clients are left in the wild.
If it turns out that this is too soon we can easily keep supporting
wl_drm for a little while longer as wlroots has not yet dropped support
for it.
The protocol states that we must send enter and leave to all text input
objects if the client has created multiple.
Only one text input is allowed to be activated by the client per seat
however.
