10:15 <narodnik> in this example: https://emersion.fr/blog/2020/wayland-clipboard-drag-and-drop/

10:15 <narodnik> data_source_handle_cancelled(data, source) calls wl_data_source_destroy(source)

10:15 <narodnik> but i'm getting a segfault there. is this code correct?

10:28 <narodnik> my version looks more like: https://agorism.dev/uploads/handle_cancel.rs.txt since i'm working with raw C ffi in rust

10:28 <narodnik> it crashes on this line: let version = (display.client.wl_proxy_get_version)(proxy);

12:27 <wlb> weston Issue #979 closed \o/ (Weston 14 will affect the performance of glmark https://gitlab.freedesktop.org/wayland/weston/-/issues/979)

12:49 <throwthecheese> Anyone have any knowledge on wlroots? I'm trying to compile laikawm and the process would always get stuck with an error about the enum zwlr_layer_surface_v1_keyboard_interactivity not being declared although said enum is provided by the wlroots headers

12:53 <throwthecheese> I would like to know if the usage of zwlr_layer_surface_v1_keyboard interactivity has changed as to require redefinition in recent versions

13:33 <Consolatis> throwthecheese: suggest to ask in #wlroots at libera IRC

13:37 <Consolatis> narodnik: the protocol states: > The client should clean up and destroy this data source.

13:38 <Consolatis> so calling wl_data_source_destroy(source) in the handler sounds like the correct thing to do

13:55 <narodnik> thanks, idk why it segfaults for me...

13:59 <kennylevinsen> throwthecheese: laikawm's last commit was 5 years ago, so it probably assumes wlroots 0.8 or something. There will be a *lot* of breaking changes between that and the current 0.18.2, and it probably assumes other old dependencies as well (despite not being explicit about them). You'll either need to use old deps or port it to newer deps.

15:12 <narodnik> for some reason when I free wl_data_source inside data_source_handle_cancelled() I'm getting a segfault

15:13 <narodnik> wl_proxy_marshal_flags(source, WL_DATA_SOURCE_DESTROY, NULL 3, WL_MARSHAL_FLAG_DESTROY);

15:13 <narodnik> i'm freeing it like this, which matches what wl_data_source_destroy(source) does

15:15 <narodnik> and if i try to do: wl_proxy_get_version(source) then i also get a segfault. so it seems the source was already freed somewhere else?

15:16 <narodnik> am i missing anything?

15:22 <davidre> try run with something sanitiizer or valgrind?

18:10 <any1> emersion: I have a display that gives me an EDID with 3 preferred resolutions. Is that normal?

18:38 <emersion> hm, that doesn't seem normal

18:39 <emersion> would need to check the specs again

18:46 <zamundaaa[m]> FWIW with my display, the kernel tells me it has two preferred modes as well

18:47 <zamundaaa[m]> One it infers from the normal EDID stuff, the other from a DisplayID extension block

18:48 <any1> My EDID has 3 blocks and the third one has two modes, both marked as "preferred". One is at 60Hz and the other at 30Hz, same resolution. :p

18:50 <any1> Skimming the spec, it looks to me like it's just not specified

18:53 <any1> Anyway, thanks for you input!

21:13 <outfoxxed[m]> I'm trying to create a wl_buffer using zwp_linux_dmabuf, however I'm kind of lost. I've got my tranches from get_default_feedback but I don't know how to actually create the dmabuf to use in zwp_linux_buffer_params. I've looked at a couple clients using xf86drm.h and gbm.h, but haven't found any documentation for the process, which I'd like to read instead of blindly copying. Anyone have information on it?

21:19 <soreau> there's https://wayland.app/protocols/linux-dmabuf-v1 and https://docs.kernel.org/driver-api/dma-buf.html but they don't seem to reveal where the dmabuf fd and other parameters come from

21:19 <soreau> in wlroots, there are four allocators, gbm, shm, dumb and udmabuf

21:20 <soreau> you can find these here https://gitlab.freedesktop.org/wlroots/wlroots/-/tree/master/render/allocator

21:30 <outfoxxed[m]> The kernel page seems to link to a different API than the one that seems to be commonly used by applications and wlr. Wlr itself seems to have code that does it, along with xdpw which can be copied, but I was hoping for some explanation of what it actually does, or docs for libdrm / libgbm that I haven't been able to find
