Current wine versions (with yabridge) do not provide SKIP_TASKBAR atom
so current implementation does not work at all for yabridge.
Reason SKIP_TASKBAR check was introduced because there was a edge case
with PixelComposer which spawned as popup instead of top level window.
That app spawns now normally as toplevel with both old and current wine
versions so removing the SKIP_TASKBAR check makes yabridge popups work
for any wine version.
Note:
After extensive testing wine-staging and non staging verisons they
report atoms very differenly:
wine-staging 9.21 reports all atoms in NET_WM_STATE while non stage and
anything above that report only single atom there or non at all
* Detect WM_HINTS popup (yabridge popups fix)
Many windows popups have:
WM_HINTS(WM_HINTS) Client accepts input or input focus: False
Which is a good indicator window SHOULD be a popup.
This is true for example on yabridge plugins and some other apps.
However toplevel windows have this property True. In order to
differentiate them we check if there are no decorations on the window
(client) and this property is False.
Its applied ONLY to _NET_WM_WINDOW_TYPE_NORMAL windows since its most
generic one that comes up.
This was tested across many apps: Reaper, Ardour, Godot, MaterialMaker,
PixelOver, PixelComposer, Steam, Steam games (both windowed and
fullscreen), Fusion 9, Unity and others I have.
There are no regression seen in any of tested apps and fixes yabridge
popups.
Additionally check if MOTIF has functions that should not be in popup
Combine wmhint popup check with skip_taskbar.
wmhint is only considered to be a popup if application has skip_taskbar
atom.
Fixed edgecases so far:
BattleNet spawning as popupp
PixelComposer spawning as popup
Notably, `xcb` 1.7.0 made `XidNew::new` no longer unsafe, so remove all
of the unsafe blocks wrapping `XidNew::new` calls. Most of these were
for creating fake windows in the unit tests, but a few were in `xstate`.
Ardour uses UTILITY atom all over the place for toplevel windows:
Plugins, Dialogs etc
However it does not provide any MOTIF_HINTS at all.
WeChat however uses them for popups and also provides MOTIF_HINTS with
flags 0x2 indicating that only decorations are active. MaterialMaker
also follows what WeChat is doing for right click menus.
This fix assigns UTILITY as popup ONLY if MOTIF_HINTS are provided and
functions are not active.
Couple of apps like Godot mark their windows
(_NET_WM_WINDOW_TYPE_UTILITY) with override_redirect which makes them
popup by default. Potentionally is_popup can be overriden in case MOTIF
functions exists with so no_function_motif would be false.
This fix prefers override_redirect in case that scenario comes up.
Closes#294
Some wine apps expect WM_STATE to be updated when mapping/unmapping
windows. Unless handled properly wine app would timeout while waiting
for update state
Fixes#302
`wl_clip_persist` hands satellite a `WritePipe` with the `O_NONBLOCK`
flag, which prevented more than 64 KiB (the Linux pipe capacity since
2.6.11) of selection data to be transferred. Since my research concluded
having `O_NONBLOCK` on Wayland's pipe transfer ends was probably valid,
I implemented basic handling for such a scenario.
I previously considered just using `fcntl` to remove the `O_NONBLOCK`
flag, but decided that was way too hacky, as it would not resolve the
underlying problem (which could easily be triggered by the receiving
program resetting `O_NONBLOCK` during the `write_all`.
The previous method of converting X selections had some flaws, including
one where XWayland would fail to send the necessary PropertyNotify
events if multiple INCR requests were sent to the same selection at
once. By using `write_to` to create a FIFO queue and `next_conversion`
to advance the queue, we can guarantee only one request is being
converted at a time, working around this issue.
Both PRIMARY and CLIPBOARD were using the same target atoms for their
property. When both are simultaneously requested (the behavior of
`wl-clip-persist --clipboard both`), the first would delete the property
the second was prepared to write data to, resulting in getting the
GetProperty reply containing the failure data.
This commit distinguishes `target` as the atom of a mime type contained
within `TARGETS`, and `property` as the atom which contains both data of
`target` and which selection requested it.
The SelectionClear event was previously calling `handle_new_owner`,
which relies on `SelectionClear` being sent only after a
`SetSelectionOwner` event. Even so, the
`XFixes::SelectionEvent::SetSelectionOwner` event already handles this
(and more obviously so). The result was that whenever Wayland owned the
X selection and X took it back, `handle_new_owner` would be called
twice, as would all of the machinery involved in acquiring a selection.
This behavior manifests as a bug if Wayland quickly reclaims ownership
of the selection, which can cause the selection event to be cancelled
before getting the SelectionNotify response is received, resulting in an
empty Wayland selection.
The clipboard and primary selections previously used the same atom to
store TARGETS when queried for them by `handle_target_list`. When a
program requests both selections simultaneously, problems such as one
selection using the target list of the other, then deleting it and
requiring the second target to get the selection targets again could
occur. This was observed when using `wl-clip-persist` and could result
in selection desyncs.
This change gives a unique atom to each primary and clipboard selection
targets so they no longer compete over the same property. It also adds
updates to the `copy_from_x11` intergration to test for this issue.
The catch-all case of `handle_client_message` now logs the atom's name
instead of its opaque atom id.
`get_atom_name` now warns there was an error and returns a filler name.
Since most the use of `get_atom_name` is in logging, this makes those
logs easier to read.
The integration tests now use `formatted_timed_builder` logger
constructor, which should unify the look of logs between the integration
tests and the main binary.
LuckShiba's commit was not formatted with `rustfmt`, so I took the
opportunity to do some additional refactors.
Some bulky match constructions in xstate/selection were made more
compact as well.
Brought to my attention by #252, several `unwrap`s exist on code whose
failure does not justify the termination of the program, so I took some
time to replace them with proper error handling.
The request for TARGETS in `handle_selection_request` used `unwrap`.
Since the code for a failure of responsing to `SelectionRequest` exists,
it simply uses that.
`handle_target_list` now early returns if receiving the
`GetProperty` request fails.
`handle_new_owner` does not update the timestamp for the last selection
on failure.
`set_owner` now returns a `bool` to indicate whether the
`SetSelectionOwner` and `GetSelectionOwner` requests succeeded and
whether they transferred ownership successfully or not. The call spots
have also been modified to not change the `selection_state` if this call
fails.
Due to an oversight, if `XState` had both a valid primary selection
and a valid clipboard selection, `handle_selection_property_change`
would early return after `check_for_incr` determines the primary selection
existed but was not the recipient of the `PropertyNotifyEvent`, preventing
INCR events from ever reaching the clipboard. An addtion to the
`incr_copy_from_x11` integration test validates this fix.
Also fixed was a missing check in `WaylandSelection`'s `check_for_incr`
to confirm the property requesting more data is indeed the property the
selection is responsible for. I could not figure out how to write an
integration for this mistake, but it is obvious enough in hindsight.
Since the range end was always encoded in the data length, calculating
the end of the selection is a bit cleaner and removes a potentially
confusing slice operation on a slice.
Resolve Clippy's `too_many_arguments` lint on
`handle_selection_request` by removing the `success` and `refuse`
parameters and returning a bool indicating which needs to be run.
Use the helper functions defined last commit to simplify
`incr_copy_from_x11`
Reduce the `match` statement checking if the target is the TARGET
atom to an if statement. Although using `match` statements as
`if`/`else if`/`else` chains occur elsewhere, this one is both only 2
cases, and already of particular relevance to the current work.
Refactor `paste_impl` to be much easier to read. I did this code algebra
way back while investigating #142, but since I never figured that out,
the change has just been sitting in my stash.
refactor: simplify paste_data logic, some unnests
Since the connection handshake establishes the most data a request can
send, if the data length exceeds that limit, we can follow ICCCM 2.7.2
sending the INCR property and continuing to send data via PropertyNotify
events.
To test the changes, we create `XState::set_max_req_bytes` to forcefully
trigger the INCR mechanism in integration test runs with a constant,
substantially less amount of data.
Also includes some light refactoring of the popup flow in general
and trimming down some unused code.
I suspect this may cause some windows to unexpectedly become popups when they
otherwise shouldn't, but that's a bridge we'll cross when we get there.
Fixes#110 and #112.
Satellite will now force Xwayland to always render with the native
display resolution, and just scale surface sizes accordingly. As a result,
applications won't really respect DPI, but this can be adjusted through
the same means as with normal X11.
Part of #28.
