Features:
- Debug-only tracking of objects by type. See
get_driver_allocs_by_object_type et al.
- Debug-only Breadcrumb info for debugging GPU crashes and device lost
- Performance report per frame from get_perf_report
- Some VMA calls had to be modified in order to insert the necessary
memory callbacks
Functionality marked as "debug-only" is only available in debug or dev
builds.
Misc fixes:
- Early break optimization in RenderingDevice::uniform_set_create
============================
The work was performed by collaboration of TheForge and Google. I am
merely splitting it up into smaller PRs and cleaning it up.
On Windows this allows to avoid having to change the owner of the window
after it has been created, which in rare circumstances may cause the
window to bug out.
Allocated XImages are improperly free'd with XFree.
The X11 documentation says that XImage should use
XDestroyImage to free both the image structure and
the data pointed to by the image structure.
Also fix a potential use-after-free bug.
- Make warnings print only once per session.
- Tweak the message to be less confusing, and mention that the issue
most likely stems from a graphics driver limitation.
Input events go to the tooltip because it's added to `popup_list` in
DisplayServer `popup_open`. I think there's no harm in tooltips being omitted
from the list, so this commit blocks non-popup windows from being added if they
have `FLAG_NO_FOCUS` and `FLAG_MOUSE_PASSTHROUGH`.
I'm not happy with this way of detecting tooltips. It'll also catch other
windows where this behavior may or may not be wanted.
I thought about adding `FLAG_TOOLTIP`, but went with the smaller change for
now.
Fixes#79500.
usleep(3) was declared obsolete in POSIX.1-2001 and removed in POSIX.1-2008.
nanosleep(2) was recommended to be used instead.
`OS::delay_usec()` internally uses `nanosleep()`.
This also uses large number separators for improved readability.
This is a workaround for the most critical portion of the WM focus bug
described in #68305. On some specific X11 WM configurations, the
editor's main window and any popups it creates will fight for focus,
which causes a total system lockup due to mouse and keyboard input being
stolen as well. Getting out of this infinite loop requires force
restarting the system.
It can be tested with the following shell script:
```bash
!#/bin/sh
godot4 &
sleep 30
pkill -x godot4
```
The workaround identified in #68305 is to remove the call to
XSetInputFocus in the ConfigureNotify event handler, so I have removed
the conditional block that calls this as well as the setup code above it
since there is no need to allocate the memory for the variables if they
won't be used in that call anymore.
This is just a hack and is not a complete fix for #68305. Multiple
developers are collaborating on a proper fix in the discussion in that
issue, but time is a valuable resource that no one has enough of, so I
am committing this workaround as a stop-gap to prevent the most critical
problem while we work on a full solution for the underlying cause.
This adds a new enum `KeyLocation` and associated property
`InputEventKey.location`, which indicates the left/right location of key
events which may come from one of two physical keys, eg. Shift, Ctrl.
It also adds simulation of missing Shift KEYUP events for Windows.
When multiple Shifts are held down at the same time, Windows natively
only sends a KEYUP for the last one to be released.
