On KDE Plasma, wl-paste hangs when the clipboard is empty #149

Closed Zesko closed 9 months ago

Zesko commented 2 years ago

Description of the problem or steps to reproduce

  1. Use KDE Plasma Wayland instead X11
  2. Install micro and wl-clipboard instead xclip.
  3. Cleanup Klipper (KDE System Tray Clipboard) that will be empty.
  4. Try to open micro in Konsole (KDE default terminal)

Result: Micro can not be opened in Konsole when using wl-clipboard because wl-paste is empty or no wl-paste. Micro waits until copy any text from other application, then it will be opened.

Specifications

$ wl-copy --version
wl-clipboard 2.1.0

$ micro --version
Version: 2.0.11
Commit hash: 225927b9
Compiled on August 09, 2022

OS: Manjaro KDE Wayland (Latest version, testing branch) Terminal: konsole (KDE default terminal)

YaLTeR commented 2 years ago

Hm, how's this a wl-clipboard issue? I'm pretty sure wl-paste doesn't hang when the clipboard is empty.

Zesko commented 2 years ago

I see micro probably has this issue. Thanks!

Zesko commented 1 year ago

I'm pretty sure wl-paste doesn't hang when the clipboard is empty.

But I can reproduce this issue: wl-paste hangs in Konsole on KDE when the clipboard is empty.

Steps to reproduce the behavior:

  1. Use KDE Wayland on VM
  2. Uninstall xclip
  3. Open a terminal e.g. Konsole
  4. Cleanup Klipper (KDE System Tray Clipboard) instead wl-copy --clear (<-- This causes the issue of wl-paste later)
  5. Run wl-paste, but it hangs and waiting for wl-copy any text
Zesko commented 1 year ago

I checked wl-clipboard-rs that has no issue. wl-past does not hang when the clipboard is empty.

bugaevc commented 1 year ago

Hi! 🙂

Please try to reproduce this with WAYLAND_DEBUG=1 and show me the logs. As in, run this:

$ WAYLAND_DEBUG=1 wl-paste

with wl-paste from wl-clipboard proper and from wl-clipboard-rs. Maybe that would shed some light at what the difference in behavior is.

Zesko commented 1 year ago

Use wl-paste that hangs when Klipper (the clipboard) is empty on KDE Wayland.

bugaevc commented 1 year ago

So KWin is not sending out a selection when we create a data device?

bugaevc commented 1 year ago

Please show me how the same looks with wl-clipboard-rs, too. Surely it also uses wlr-data-control in a very similar way.

I have no idea, but the selection has nothing to do with this issue, I guess.

Yes, sure. wl-clipboard-rs version 0.7.0.

wl-paste does not hang and is closed when the clipboard is empty. this is the expected behavior

bugaevc commented 1 year ago

Hmm, so wl-clipboard-rs is doing a sync, and if no selection event is received, it immediately says that the clipboard is empty. Which is probably fine as a workaround, but the protocol is rather clear that the compositor is supposed to send a selection(nil) event immediately:

https://github.com/bugaevc/wl-clipboard/blob/d83a629822d83b73ffa0f2a6e1c82b1caab30b8d/src/protocol/wlr-data-control-unstable-v1.xml#L128-L129

Could you please report this to KWin? Feel free to link back to this comment as an explanation of what KWin does wrong.

Zesko commented 1 year ago

I see that wl-copy --clear does not work on KDE Wayland.

$ wl-copy test
$ wl-paste
test
$ wl-copy --clear
$ wl-paste
test

Gnome Wayland has no issue with that.

Did you reproduce this issue on KDE Wayland?

I am using: kwin_wayland 5.27.2 KDE Plasma 5.27.2 KDE Framework 5.103.0 Qt 5.15.8 Wayland

https://bugs.kde.org/show_bug.cgi?id=445751

That... seems unlikely to be related.

Also, I'm not claiming that KWin and wl-clipboard don't work together — they do, and I do test wl-clipboard under KDE all the time. But apparently things became more broken while I was away.

What I am saying though, is that they're supposed to send a selection() event immediately after a client creates a data device, which, according to your logs, they don't. If there's nothing copied, they should still send a selection(nil). This is the same issue as https://github.com/bugaevc/wl-clipboard/issues/158.

I'll look into the --clear issue, but it's likely another instance of Klipper trying to preserve clipboard contents when it should not. It's likely not their fault either — unfortunately the data-control protocol does not make it clear why the clipboard contents has disappeared (has the owning client died? was there an explicit set_selection(nil)?).

bugaevc commented 1 year ago

I can reproduce both of there. The --clear issue is indeed KDE itself (Klipper?) taking over the selection after wl-copy --clear clears it successfully (look for application/x-kde-onlyReplaceEmpty). They should not, but they can't because the protocol doesn't differentiate between the two cases.

And they don't send selection(nil) upon creating the data device indeed, so that's definitely something they should fix.

Also, wl-copy dies from a SIGPIPE once the destination is no longer interested in our clipboard contents (perhaps they only want the first few bytes to sniff the type better?), we should definitely fix that.

bugaevc commented 1 year ago

The SIGPIPE "crash" should have been taken care of by https://github.com/bugaevc/wl-clipboard/commit/3b8c9a091a43840e6aa1a844c6859c823e137e26

martin-kokos commented 1 year ago

I also encounter this problem (when password manager KeePassXC clears the clipboard some time after copying a password from it). This causes a program that tries to grab the contents via wl-paste (tmux) wait for content aka. hang.

... and just hangs there. wl-clipboard 2.1.0

bugaevc commented 1 year ago

This also looks like a bug in whatever software actually owns the clipboard contents at the moment. KWin is correctly passing us the offer (zwlr_data_control_offer_v1@4278190080), and wl-paste is correctly calling receive("text/plain;charset=utf-8") on it (and "text/plain;charset=utf-8" was indeed among the offered types). Then it waits to receive the data, but never does.

You're going to have to debug who owns the clipboard contents at the moment, I'm afraid.

I've just realized, I am running KeepassXC in QT xcb mode (due to a bug), so in Xwayaland, if that is relevant.

I'm on kde using wayland and not using the klipper/clipboard manager. Here wl-paste only hangs if the Xwayland clipboards are empty.

wl-paste returns Nothing is copied if I clear the wayland clipboard by copying text (in a native wayland program, e.g. kwrite) and then close the program (confirmed by clipboard status in qdbus org.kde.KWin /KWin org.kde.KWin.showDebugConsole).

but wl-paste hangs if I copy text from a Xwayland program, then clear the X clipboards with xsel -bc; xsel -pc; xsel -sc

Trying again with version 1:2.2.1-1 on arch linux & kde it seems fixed
