bug#72254: 29.4; Cannot yank media when image come from Gnome-shell screenshot

[Sébastien Gendre]

[-- Attachment #1: Type: text/plain, Size: 2192 bytes --]

Hello,

I got a bug when I try to yank a screenshot made with Gnome-shell into
an org-mode buffer.

From the reply I get on the Org-mode mailing list, the bug come from
Emacs itself.


What I do:

* From the system menu of Gnome-shell, I choose the action to take a
  screenshot

* I took a screenshot from a selected zone, confirm the screenshot and
  got a notification message telling me "You can past the screenshot
  from the clipboard"

* On an Org-mode document, I place the point where I want to past the
  screenshot and call the Emacs function "yank-media"


What I get:

* In the mini-buffer, I get the error message:
  "Wrong type argument: sequencep, image/png"

* If I go into the "*Messages*" buffer, the full error message is:
  "seq-do: Wrong type argument: sequencep, image/png"

* If I enable debug-on-error, here is the full backtrace:

Debugger entered--Lisp error: (wrong-type-argument sequencep image/png)
  mapc(#f(compiled-function (elt) #<bytecode 0x1ebc9d0d6093f55d>) image/png)
  seq-do(#f(compiled-function (elt) #<bytecode 0x1ebc9d0d6093f55d>) image/png)

  execute-extended-command(nil "yank-media" "yank")
  funcall-interactively(execute-extended-command nil "yank-media" "yank")
  command-execute(execute-extended-command)


What I expected:

* The image present in the clipboard is attached to the org-mode heading
  and a link to this attachment is created under the point


Versions:

* Org-mode: 9.7.2

* Emacs: 29.4

* Gnome-shell: 46.3.1


Best regards

If instead of running `yank-media' at this point, what happens if you
evaluate:

   (gui-get-selection 'CLIPBOARD 'TARGETS)

following patch and see if it improves things?

How did you evaluate the `cl-defmethod'? I tested with 'C-x C-e' after
the form.

Maybe visiting yank-media.el and doing 'M-x eval-buffer' will help.

Yes, itʼs still using the old `gui-get-selection'.

Maye you need to rebuild emacs with the patch.

Thatʼs exactly what I do, so I donʼt understand why itʼs not working
for you. What about if you replace the body of the `cl-defmethod' with
something like

(message "Hello world!")

and evaluate it, does that make any difference?

OK. Weʼll work on that later if we have to.

Hearing that OP uses GNOME, are we sure OP is not running the PGTK port?
If that is the case, AFAIU context will not be x?

FWIW, I tried copying an image to clipboard and the gui-get-selection
above returns [TARGETS image/png] in a PGTK build of the emacs-30
branch.

Try this `cl-defmethod' instead.

Po Lu, is this the right level to fix this? Or should we handle
'CLIPBOARD + 'TARGETS specially in `pgtk-get-selection-internal'? (And
maybe we should add "&optional time_stamp terminal" to the
`cl-defmethods' in pgtk-win.el)

I would prefer to treat this as a bug in GTK by installing a workaround,
perhaps in the spirit of:

That works for me (once I remove the '&' from `val' in the make_vector
call) on Fedora 40 with a pgtk emacs.

An x11 emacs on the same system doesnʼt need a similar fix. I guess
this is the GTK folks removing 'legacy' stuff.

Right.  Has anyone anything further to say before this is installed?

Not me. I assume youʼre putting it in emacs-30?

I donʼt see this change on the emacs-30 branch, is anything more needed?

Thanks

No, the patch was lost among the host of matters I had to attend to.
Eli, is this still OK for emacs-30?

It looks like the change will affect any selections from the
clipboard?  If so, it's a bit scary to install it so late.  Can we
change the patch such that it affects only media selections?

It only affects pgtk builds, and only when emacs requests the list of
supported formats for yanking, which only `yank-media' does.

How do you see that it affects only PGTK?

But if these two conditions are the only cases where this method will
be used, I guess we can install it on the emacs-39 branch after all.
Although the problem is hardly urgent.

The change is to `pgtk-get-selection-internal', which only exists in
pgtk builds.

Itʼs an annoying issue, since org-mode has gone to the trouble of
implementing support for `yank-media' it would be nice if it worked
everywhere (and some distributions have started shipping pgtk-emacs as
their default emacs)

Well, that's easy: for it only modifies pgtkselect.c.

OK.

I think we (implicitly or otherwise) promised the OP that this would be
addressed in Emacs 30.

I guess I looked at the wrong patch, then: it was for x-win.el.

That was my original debugging patch which showed that the reporter
was using pgtk, since it didnʼt do anything ☺️

I was preparing to install this patch when I noticed that commits for
the pretest had been created but that the pretest had yet to be
released.  Perhaps this should be postponed till Andrea puts the tarball
out, am I correct?

That's up to Andrea (CC'ed), it depends on where did he pause the
make-tarball procedure.

I suggest bugfixing on the branch happens indipendently of the release
process, I'm not bothered if commits are installed (worst case they will
not be included in the pretest).
