Doc Type: Bug Fix
Doc Text:
Previously, clipboard images were truncated when copying from the SPICE client to guest, as clipboard data size was incorrectly calculated as a text string. Data size is now calculated according to its type so that copying and pasting images between client and guest works as expected.

Description Christophe Fergeau 2014-11-06 11:02:15 UTC
mingw-spice-gtk build for 3.5 has http://cgit.freedesktop.org/spice/spice-gtk/commit/?id=a8f2e2d9906f9908ab6cae0b9c36d99e5b49d05d in order to fix bug #1090122. This caused a regression with image c&p fixed by http://cgit.freedesktop.org/spice/spice-gtk/commit/?id=43e3f6ea012236b1c3759a48b24026bdeff5d7e0

+++ This bug was initially created as a clone of Bug #1154719 +++

Description of problem:
When I build spice-gtk from upstream and use it in smoketest, copy/paste of images from client to guest fail with being unable to copy the images. 

The same tests pass from guest to client.

Version-Release number of selected component (if applicable):
Built spice-gtk from latest upstream => spice-gtk 0.25.48-af73-dirty

How reproducible:

Steps to Reproduce:
1. Open guest with virt-viewer and spice-gtk (built from upstream) by LD_LIBRARY_PATH=/usr/local/lib virt-viewer spice://localhost?port=5901
2. Copy any image from client
3. Open http://ie.microsoft.com/testdrive/browser/Editing_Paste_Image/
4. Try pasting image using <Ctrl+v>
5. Image will not get copied
6. Try copying any image from guest
7. Open same webpage in client
8. Try pasting image using <Ctrl+v>. Image will get pasted. 

Actual results:
Images gets copied from guest to client but not client to guest. 

Expected results:
Image should get copied in both directions.

I checked the commits and narrowed the failure to this commit. Copy-Paste images from client to guest fails after this commit and passes before this commit. 

commit a8f2e2d9906f9908ab6cae0b9c36d99e5b49d05d

    Ensure '\0' is not part of text clipboard data
    On Windows, with some versions of gtk+, GtkSelectionData::length
    will include the final '\0'.
    When a string with this trailing '\0' is pasted in some linux
    applications, it will be pasted as <NIL> or as an invisible character,
    which is unwanted.
    This commit ensures the length we send to the agent does not
    include any trailing '\0'.

> When I build spice-gtk from upstream

Just a note for future bugs, bugs in the upstream codebase should be filed on https://bugs.freedesktop.org/
Bugs in the Fedora component are for bugs you hit when using the fedora packages.

Thanks a lot for bisecting it down to the faulty commit, this is really helpful in fixing it!

Fixed upstream in http://cgit.freedesktop.org/spice/spice-gtk/commit/?id=43e3f6ea012236b1c3759a48b24026bdeff5d7e0 (and previous commit), will be in upcoming 0.26 release.

Comment 2 Vaclav Ehrlich 2014-11-11 11:04:17 UTC
Client Win7/32 mingw-virt-viewer-0.6.0-2.el6_5
Guest Win7/64 (Guest tools 3.5-5), RHEL6.6-64 (spice-vdagent-0.14-4)

Copy from client to guest is not working (Win7's Paint shows message 'The information on the Clipboard cant' be inserted into Paint')

Copy in opposite direction works like a charm.

Comment 4 Christophe Fergeau 2015-06-05 10:27:19 UTC
Will be resolved by the rebase.

Comment 5 Uri Lublin 2015-06-15 23:10:40 UTC
Rebase built -- mingw-spice-gtk-0.26-1.el7ev.
I put -4 in built-in field which is part of mingw-virt-viewer-2.0-2.el7ev
which is a part of rhevm-spice-client 3.6-2 build
