Description Jonathan Haas 2019-10-08 17:56:55 UTC
Description of problem:

There is a drag & drop regression in mutter 3.34, see referenced Gitlab bug.

Version-Release number of selected component (if applicable):
mutter-3.34.0-5.fc31.x86_64

How reproducible:
Always

Steps to Reproduce:
Follow the steps in Gitlab, or follow the following steps:
1. Open Gimp And Nautilus
2. Open "Open File" dialog in Gimp
3. Drag image from file dialog to Nautilus

Actual results:
File is successfully moved/copied in Xorg session, but it fails in Wayland session

Expected results:
Works in both sessions

Additional info:
After bisecting the code, Sergio Costas found that the bug was inserted in the commit 634f512b :

Nov 22, 2018 15:56:24 CET
wayland: Integrate with MetaSelection
Make MetaWaylandDataDevice use MetaSelection and MetaSelectionSource to
handle primary/clipboard/dnd.
!320 (merged)

This may be related with 1669730 but according to the Gitlab issue seems to be a new issue in Gnome 3.34.

Comment 1 Jonathan Haas 2019-10-08 19:20:23 UTC
Reason for blocker request: Drag & drop is basic functionality of the desktop, also receiving dropped files is probably basic functionality of nautilus.

Comment 2 Adam Williamson 2019-10-08 21:45:33 UTC
at least +1 FE for me.

Comment 3 Chris Murphy 2019-10-09 04:13:12 UTC
I'm inclined toward +1 blocker. I agree drag and drop in a GUI is basic functionality, and also Wayland is the default protocol/compositor being used on Workstation. And also it's a regression.

But for sure +1 FE.

Comment 4 Kamil Páral 2019-10-09 13:09:21 UTC
I can confirm the problem. Under Wayland, Nautilus doesn't accept drag&dropped files.

Comment 5 Kamil Páral 2019-10-10 16:28:01 UTC
-1 blocker +1 FE. I think that dragging files is an extremely uncommon operation, and this bug is the first time I realized that it's even possible. If somebody can demonstrate a common real-world usage, I can be convinced.

Comment 6 Kevin Fenzi 2019-10-10 17:32:32 UTC
-1 blocker, +1 FE (I am with Kamil here)

Comment 7 Mohan Boddu 2019-10-10 17:33:48 UTC
I dont use drag and drop at all now, but I remember trying it while I started playing with computers.

Based on my usage now I would say +1 FE but I can see new people (like I was) might see it as an issue.

Comment 8 Adam Williamson 2019-10-10 17:34:06 UTC
That's at least +4 FE, so marking accepted FE for now.

Comment 9 Michael Catanzaro 2019-10-10 19:09:28 UTC
This should probably be considered alongside the two clipboard FE bugs, bug #1751646 and bug #1758873, since it's going to be the same underlying clipboard manager issue for all three. (Clipboard and drag-and-drop internally both use much of the same data transfer code.)

Comment 10 raster 2019-10-12 10:44:31 UTC
I can confirm that, with the code in MASTER, the drag and drop between nemo and nautilus, and between my test app and nautilus, does work fine. Thanks!!!!!!

Hi.

gnome-shell-3.34.1-4.fc31, mutter-3.34.1-12.fc31 has problem with drag & drop under Wayland. This don't work from Nautilus to Gimp, Chrome, etc.

Comment 18 Simone Marchioni 2020-01-03 11:32:31 UTC
Hi,

don't know if it's related to this bug, but drag & drop doesn't work from Nautilus to Thunderbird either.
Fedora 31 with latest updates installed as of 3/1/2020.

Relevant versions:

gnome-shell-3.34.2-1.fc31.x86_64
mutter-3.34.2-1.fc31.x86_64
thunderbird-68.3.1-1.fc31.x86_64

Try to drag a file to a Thunderbird message: the file is not being attached. In the past it worked flawlessly.

Comment 19 makal 2020-04-19 15:49:31 UTC
Hi,

Don't work between file-roller and Nautilus too.
