qemu 6 & 7.1 crash at qemu_xkeymap_mapping_table(), (built with gtk) #13

Closed khallebal closed 1 year ago

khallebal commented 2 years ago

From what i have understood of the trace is that qemu searchs for a (X)server X11;quartz,win32 or broadway and doesn't find any? is this a good assumption? Anyway the trace report is include.

It has nothing to do with Xlibe, sorry for the noise.

khallebal commented 2 years ago

Can't close this thing?

waddlesplash commented 2 years ago

It likely does have to do with Xlibe. QEMU probably expects to be able to get a full keymap, which Xlibe doesn't provide, and it doesn't expect this to fail (which is reasonable, Xlibe isn't really "within specifications" in doing this.) Whether we can or should do something about it is another matter.

khallebal commented 2 years ago

Ah okay i didn't know that, but still that doesn't explain the crash at start up, it should just go through the checks and then issue the warning at the end of the gd_get_keymap() function and return NULL, why does it [crash?.] I wonder how @X547 dealt with this keymap issue in wayland?

waddlesplash commented 1 year ago

Wayland uses real keymaps. Since GTK now uses the Wayland layer instead of Xlibe, I think we can close this.

khallebal commented 1 year ago

No problem, you have more important things to do.
