bug#20810: 25.0.50; tabulated-list is broken

[Michael Albinus]

Try "M-x buffer-menu". It results in an error message. Bisecting shows,
that this error was introduced by

Bisecting: 0 revisions left to test after this (roughly 1 step)
[c205098b6a8bd3b13256803f86f6863558a7a34e] * lisp/emacs-lisp/tabulated-list.el: New optional print method

Other packages using tabulated-list are broken as well, for example debbugs-gnu.

bug#20810: 25.0.50; tabulated-list is broken

[Artur Malabarba]

I can't reproduce that. Could you try emacs -Q?

Also, what's the error message? And could you try debug-on-error?

Hmm, I did a "git pull" and recompiled everything, and the problem is
gone for me with the `buffer-menu' command. But it still remains for
`debbugs-gnu'.

The second argument s2 of `debbugs-gnu-sort-id' is (nil nil), which
doesn't look like a valid sort item. Does `tabulated-list-print' calls the
sort function with possibly incorrect items? Or is there an incompatible
change? etc/NEWS mentions a change of `tabulated-list-print', but I don't
see how it is related to the problem.

Best regards, Michael.

Ok, I confirm I have it for debbugs as well.

Indeed.

Answer to both of these should be "no", but clearly at least one
isn't. :-) I'm looking into it.

As part of that change, the sorting logic got refactored a bit, so I
probably messed it up. It doesn't really have anything to do with the
new printing method that's actually announced in the news.

bug#20810: 25.0.50; tabulated-list is broken

[Artur Malabarba]

Ok I've spotted the problem. The logic I implemented assumed that the
`tabulated-list-printer' function (which is used to print each entry)
would always leave point after the printed content, which is not what
debbugs does. Debbugs uses this to also print some content at the top
and bottom of the buffer the first time it is called

I'll find a better way to write this.

Indeed. Thanks!
