Hi,

Very often, when saving a new message to an nnml-group, that has
accented characters (for example "stéphane"), and then entering that
group, the summary buffer does not show this new message.

Only after several (gnus-group-get-new-news) and switching back and
forth to other groups, after a while the new message shows up.

How could this be solved (and/or debugged) please?

TIA for any hints,
-- 
           Peter

Can you tell us your Gnus version? Things have changed fairly
dramatically in this area over the past couple of years. Your agent and
cache settings will be relevant, too.

Thanks,
Eric

It's in the headers:
User-Agent: Gnus/5.13 (Gnus v5.13) Emacs/27.2 (gnu/linux)

Concerning agent and cache, this is the only thing, that I've
customized:

--8<---------------cut here---------------start------------->8---
nnmail-message-id-cache-file is a variable defined in ‘nnmail.el’.
Its value is "~peter/.emacs.d/nnmail-cache"
Original value was "~/.nnmail-cache"
The file name of the nnmail Message-ID cache.

I don't think there will be a whole lot you can do -- in mid-2019 I made
some fairly large changes to Gnus to use decoded group names everywhere,
and in the process fixed several bugs related to non-ascii group name. I
don't think any of that is available in Emacs 27. It's possible if we
found the exact bug that the fix could be added to 27, but I don't even
think there will be any more releases of 27 anyway (?, not sure). Your
best bet may be to wait until Emacs 28 is released.

In the mean time, can you look at the active file for this server and
see how the group name is encoded there?

Ok, then I'll wait for version 28. Do you know, when it's going to be
released?

It's UTF-8. And now I notice, that there are several lines for the same
group, if its name has accented characters. For example:

--8<---------------cut here---------------start------------->8---
stéphane 277 1 y
stéphane 280 1 y
stéphane 281 1 y
stéphane 282 1 y
stéphane 284 1 y
stéphane 285 1 y
--8<---------------cut here---------------end--------------->8---

I sure don't! Much less do I know when the various platforms will update
their packages. I sort of get the sense that it might be released within
the next year?

Well that's interesting! I wonder how that happened. That's definitely a
clue to what's going on, though again I'm not optimistic about getting a
fix to you. If you just delete all the extra lines (leaving the one with
the highest active number) does it fix the behavior you're seeing?

I've tried with one example: yes, it seems to fix it.

Which doesn't mean that the problem won't come back again, but at least
narrows the scope of the bug. Thanks for confirming that.

I still think it's unlikely that I'll be able to get a fix to you, but
I'll look into this over the next few weeks, and who knows. In the
meantime, thanks for the bug report :)

Hello Eric,

Now I use Emacs from git-master. Still the same problem.

Here some details for the group "céline":

- There is this line in ~/Mail/active: "céline 153 1 y"
- Then I reply to a message in this group with "Gcc: céline"
- This appears in the *Messages*:
  Sending...
  Sending via mail...
  Wrote /home/peter/Mail/c\303\251line/154  (2 non-printable characters)
  Sending...done
- When entering the group "céline", the new message is hidden.
- There are now 2 lines in the active file:
  céline 154 1 y
  céline 153 1 y

I guess, that this should be reproducible with any nnml group with
accented characters in the group name.

TIA for any help,
-- 
           Peter

And here a related problem:

When using "S D r" (gnus-summary-resend-message), a local copy of the
message is written to the group.

I'm guessing that there's something particular to archive group writing,
since this doesn't happen with regular nnml groups with non-ascii names.
Are you using "Céline" as your archive group, or your Gcc header for
this particular set of messages? And you're in this group when you hit
"S D r" as above, right?

Okay, I was able to reproduce this problem when archiving messages to a
group with a non-ascii name. Give me a few days and I ought have this
fixed.

Thanks,
Eric

That was much easier than I thought, I'd simply missed a group-name
encoding call when I was yanking all this stuff out a year or so ago.

If you'd like, please test the attached diff to make sure it works,
though I'm fairly sure this is it.

Eric

Hello Eric,

Thank you! This fixes apparently the first issue. But not the second
with the resending. Here the *Messages*:

Resending message to XXX...
Sending via mail...
Wrote /home/peter/Mail/c\303\251line/123
Resending message to XXX...done

Kind regards,

Yes! There were two more instances of group name encoding in that file.
I've removed both of them, will test a bit, and then push this fix later
today.

Thanks for reporting,
Eric
