Subject: 31.0.50; can't paste images with yank-media
Date: Wed, 19 Feb 2025 14:44:05 +0000

[Message part 1 (text/plain, inline)]

I was previously using Emacs that I built from commit b568ff418ce. Now I've tried to use the latest one, and I can't paste images using yank-media after using this command 'grim -g "$(slurp)" - | wl-copy'. If I go back to the b568ff418ce commit, then everything works fine.

I have instances of Emacs opened right now, and evaluating (gui-get-selection 'CLIPBOARD 'TARGETS) on the one built from the b568ff418ce commit returns '[image/png]' and i can paste the image. The one built from the latest commit returns '[]'.

In GNU Emacs 31.0.50 (build 3, x86_64-pc-linux-gnu, GTK+ Version

Visuwesh, could you please see if you can reproduce, and if so, try to
find the offending change?  This is before I installed your yank-media
changes.

This commit was pushed after Po Lu's fix for bug#72254 so it is not a
regression from that fix.

What version of Org do you have loaded?  A recent workaround for
bug#72254 was pushed for Emacs≤29 to the bugfix branch (I think?).  It
shouldn't be enabled when you run the master branch but I might have
messed up the logic of the test.  To be sure this isn't the case, can
you tell what

    (pgtk-get-selection-internal 'CLIPBOARD 'TARGETS)

returns?  If it returns the same thing, then we can rule out this
possibility.  You can skip this if you're using the version that ships
with Emacs.

The only commit that touched src/pgtkselect.c after b568ff418ce is
Paul's commit intended to pacify GCC warnings.  It seems to have changed
a function that is used by pgtk-get-selection-internal, could you please
check if reverting ff65cc9944dc0b37986d512ee8b9817c6913db36 fixes the
issue?

Thanks for reminding me, Eli.  I neglected to allot time to look at this
bug when I came across it earlier.

It would be nice if someone could check if they can reproduce the bug on
Wayland in a pgtk build.  I am still on Xorg.

Reverting the commit fixes the issue.

Paul, can you please take a look at this bug report?  Your recent commit

    commit ff65cc9944dc0b37986d512ee8b9817c6913db36
    Author: Paul Eggert <eggert <at> cs.ucla.edu>
    Date:   Sun Jan 26 22:15:49 2025 -0800

        Pacify GCC in pgtkselect malloc alignment

        * src/pgtkselect.c (pgtk_size_for_format): Remove.
        (pgtk_get_window_property): Third arg is now void **, not unsigned
        char **.  Omit last arg.  All callers changed.  Simplify
        allocation to pacify GCC 14.2.1 complaint about malloc size
        mismatching size of array: there’s no need for an extra byte when
        converting from ldata to idata.
        (selection_data_to_lisp_data): Third arg is now void const *,
        not unsigned char const *.  All callers changed.
        Omit unnecessary casts.  Make some locals more local.

seems to have introduced a regression.  Details of reproduction are in
OP.

Thanks for reporting that, and for reporting that reverting fixes the 
problem. For now I've reverted, to fix the immediate problem. I may try 
to come up with a better (less intrusive) way to pacify GCC.

I did that and installed the attached into the master branch; please 
give it a try.

It sounds like you still have a problem with current master. Do you have 
the same problem with (say) commit 
b06364f1b667e7960d1724293398179f280e910b? If so, the problem is surely 
independent of Bug#76414.

I'll cc this email to the bug-report address so that it gets to the 
person who posted the bug.
