I'm trying an email setup that involves pointing Gnus as a maildir tree
and having mbsync run from cron and, well, sync with an IMAP server.
Sometimes, if I open a mail group in Gnus, read a message, and before
leaving that mail group, go read that message on another client, the
cron job will change the message-file's flags behind Gnus's back,
causing Gnus to raise an error when I try to leave the group,
complaining that a message file it thought existed no longer exists
(because it's been renamed).
Can Gnus cope better with other programs modifying messages concurrently?

Just to clarify -- these problems are with nnmaildir and not nnimap?

And three days after that I renamed this bug to
retitle 25126 nndir reacts poorly to email flags being changed behind its back
which must be wrong. I mean, it's either nnmaildir or nnimap.
So I have to ask again -- what Gnus backend is this about, and what are
the error messages?

The example in the OP is about nnmaildir.
I don't think the details are relevant, but it happens to be being
synced from imap by an external process. For example, a maildir file
might change name from "stuff:2,S" to "stuff:2,RS" if you reply to the
message via an imap client. Or it could have been moved to a different
folder, or deleted altogether. It's not obvious to me what Gnus could do
in this situation.
I imagine you could reproduce it by visiting a Maildir with Gnus, then
renaming one of the files externally.
I imagine none of the Gnus backends (except imap) are prepared for files
to be renamed by other processes while Gnus is running?

Ah, thanks for the explanation.

I don't have any maildir dirs, which probably explains why all the
nnmaildir bug reports are languishing. Could you pack up a simple one
and mail it to me as a tar file?

Hm... it depends. I mean, ideally a `g' should feed Gnus any changed
information, but it might require that the backend in question implement
the "extended" interface that nnimap uses.

I will send you my spam folder off-list, you lucky person.
BTW, if you have imap, you can have maildir fairly easily with eg
http://www.offlineimap.org
http://isync.sourceforge.net/

I won't keep on with this, but the gnus-mock package in ELPA will give
you a clean, reproducible Gnus installation with a maildir server that
you can use for testing. I promise I'll shut up about it after this :)
