描述

Shared Clipboard --> Cannot copy and paste from one Guest to another Guest.

It only works the first time. Then it stops working.

Both guests here are Fedora 18.

Host is Fedora 18.

If you want to copy a second time, you need to first paste it to the host, and then copy again from the host, and paste it to the second guest.

It would be great if you could try to debug this a bit. We have guidelines on a wiki page<1>. Feel free to point out any possible improvements to the debugging guidelines!

[user9@localhost ~]$ ps -Af | grep VBoxClient
user9     2267  2215  0 00:35 pts/0    00:00:00 grep --color=auto VBoxClient

The "--clipboard" is not there?

VBoxClient is at the end of the line? Shouldn't it be before "--color=auto"? 

[user9@localhost ~]$ VBOX_RELEASE_LOG_DEST=file=/tmp/clipboard.log VBOX_RELEASE_LOG=+all.e.l.f VBoxClient -d --clipboard
bash: VBoxClient: command not found...
[user9@localhost ~]$

Then it says command not found?

That looks to me as though you are executing those commands on the host, or on a guest without Additions installed.

yes I executed those commands on the host.

I will try again on the guests in a couple of days.

sorry about that.

  1. Copy "testcopy1" from first guest.
  2. Pastes "testcopy1" to second guest. (Correct)
  1. Copy "testcopy2" from first guest.
  2. Pastes "testcopy1" to second guest. (Wrong. It should paste "testcopy2" not "testcopy1")

Note this is same for Windows guests also (not just linux guests).

I messed up.

I put 

[user@localhost ~]$ VBOX_RELEASE_LOG=+shared_clipboard.e.l.f

instead of 

[user@localhost ~]$ VBOX_RELEASE_LOG=+shared_clipboard.e.l.f VirtualBox

Attaching new log files (Run2).

How nice. When we announce new clipboard data, the X toolkit checkes whether we already own the clipboard and suppresses the announcement if we do. Would you care to give this build a try? It is trunk (4.2.51) as I saw from the log that you were already running that.

Thank you for the updated build.

Your fix works. You probably have to press copy twice the first time, but after that copy and paste works fine. So thank you.

Since I have debugged this this far, would you be interested to elaborate about that "press copy twice the first time"? And thanks for confirming that the fix works otherwise.

  1. Press copy "testCopy1Run3" in First Guest.
  2. Nothing pastes to Second Guest. (Wrong) (clipboard is empty for Second Guest?)
  3. Pastes "testCopy1Run3" to Host. (Correct)
  1. Press copy again on "testCopy1Run3" in First Guest.
  2. Pastes "testCopy1Run3" to Second Guest. (Correct)
  1. Press copy on "testCopy2Run3" in First Guest.
  2. Pastes "testCopy2Run3" to Second Guest. (Correct)

Interesting. Would you be able to get log files for that? Thank you.

I posted the log files before the last comment :)

Excuse me, I did not see them. Thank you, I will take a look!

comment:15 11 年 前 由 Michael Thayer 編輯

Please give this build a try. It seems that the Xt toolkit does not cope well with several operations on the clipboard in parallel, and now the other virtual machine is sending out two "new data" announcements on those occasions when the toolkit doesn't suppress the announcement. I could prevent that of course, but I preferred to keep the code simple. Which revealed this problem.

It works perfectly with the latest test build (4.2.51-86055). Thank you. Much appreciated.
