bug#34974: 27.0.50; Moving article error with duplicate suppression disabled

[Basil L. Contovounesios]

With gnus-suppress-duplicates left at its default value of nil, trying
to move an article with 'B m <group>' gives me the following backtrace:

Debugger entered--Lisp error: (wrong-type-argument hash-table-p nil)
  remhash("<redacted-message-id>" nil)
  gnus-dup-unsuppress-article(1988)
  gnus-summary-move-article(nil)
  funcall-interactively(gnus-summary-move-article nil)
  call-interactively(gnus-summary-move-article nil nil)
  command-execute(gnus-summary-move-article)

I'm no expert, and I haven't tried reproducing this with a minimal
config, but I think gnus-summary-move-article should not call
gnus-dup-unsuppress-article when gnus-suppress-duplicates is nil, right?

This issue seems to have been uncovered by the switch to hash-tables in
bug#33653.  Previously, gnus-dup-unsuppress-article called unintern,
which would not complain when its second argument gnus-dup-hashtb was
nil, even though it probably should have.

Patch to follow.

Thanks,

Sorry, this is a duplicate of bug#34973, which was reported first and
where I've now sent my suggested patch.

I was going to merge the two bug reports, but then I read that the
debbugs 'merge' command requires reports to be assigned to the same
package.

This report was created by the gnus-bug command, which assigned it to
both packages emacs and gnus and version 5.13, whereas the other report
was presumably created by report-emacs-bug and assigned to the emacs
package, version 27.0.50.

So, which package+version combination should Gnus bugs be assigned to?
How should these two reports be merged?  Does merging keep all parties
CCed, or do they have to be CCed anew?

Thanks,

Bah, and I'd sent in the "merge" command moments before. Trying too hard
to be helpful.

I see that Glenn reassigned bug#34973 to both packages emacs and gnus
before merging these two reports, thanks Glenn!

The suggested fix has been merged[1][2], so I'm closing this report.

Thanks, Basil!

It looks like the only other call to `gnus-dup-unsuppress-articles' is
wrapped in a check for `gnus-suppress-duplicates' -- I suppose it would
be enough just to wrap this one as well?

That is what the proposed patch[1] does.  Is it okay to push this to
master?

[1]: https://debbugs.gnu.org/34973#8

As I mention there, though, I'm not sure such a guard is sufficient in
the case that gnus-suppress-duplicates is enabled at a later stage, but
I will investigate and report this as a separate bug if needed.

Thanks,

Thanks for looking into this so quickly and working on Gnus in general!
And good luck with the rest of the fallout. ;)
