This should in theory prevent Nimble Kick from triggering a stack
overflow when the event loop timer procs before `IPlugView::attached()`
gets called and the plugin hasn't been registered yet. I haven't seen
any other VST3 plugins trigger a race condition here.
In some cases we would treat dead processes as not running (we could
also get EAVAIL instead of EINVAL, so it's better to just check the one
thing we should treat as a success instead).
I've seen this happen once or twice. Earlier on (in #40) we could get
away with just reparenting the window another time. But here both
reparents succeed, and the issue still happens. But a reparent notify
for `parent_window` did appear on system affected by this issue, which
is very odd. Hopefully this will help.
We should of course not expect all global memory to be a HDROP, oops.
Apparently REAKTOR sometimes uses the drag-and-drop system for its own
internal data.
Specially for @AVLinux. We currently don't build a 32-bit version of
yabridgectl though, so you'd still need that if you want to use yabridge
on an _actual_ 32-bit system.
When the user has some sort of hardening going on, we might not be able
to read the Wine process's memory. In that case this check would return
`false` even though the process is still running. To combat this, we
should explicitly check for `EINVAL` which is returned when the file
doesn't exist at all or when it's a broken 'symlink' (even though it
isn't really a symlink).
This is the same way (minus the mapping check part) that `xprop` and
`xwininfo` filter windows when clicking on them. REAPER's toplevel
window apparently doesn't process any keyboard input when the mouse
cursor is located outside of that window.
This should fix#118 without breaking our _other_ workaround from
yabridge 3.4.0 to fix the issue where a plugin would freeze if it would
try to resize itself while at the same time it sent parameter changes
from the audio thread. (and both of these issues of course are caused by
the same JUCE bug)
This is super difficult to trigger on purpose, but I did run into it at
least once just now so it seems like a good idea to at least make sure
that this doesn't happen.
REAPER initializes the plugin's editor first before reparenting the
parent window to the FX window, so our `topmost_window` didn't actually
refer to the FX window.
