nnfolder has me baffled

nnfolder has me baffled

[Randal L. Schwartz]

OK... I have nearly all the default settings, and decided to start
using nnfolder:'s to hold some of my older mail (fewer inodes).  I've
never used that nnfolder:archive thing, but it's still hanging around.

As far as I can see, there's a nnfolder-directory set to ~/Mail (the
default), except sometimes it gets set to ~/Mail/archive.  When I look
at the nnfolder:archive server, I see this:

(nnfolder "archive"
	  (nnfolder-directory "~/Mail/archive")
	  (nnfolder-active-file "~/Mail/archive/active")
	  (nnfolder-get-new-mail nil)
	  (nnfolder-inhibit-expiry t))

But before I've examined that, nnfolder-directory is ~/Mail.

So, I tried G-M'ing a group with "arch.todo" "nnfolder".  It created a
directory ~/Mail/arch/todo (note, NOT under ~/Mail/archive), which
nnml on next invocation decided was an nnml group.  It also took about
three or four tries to get everyone to agree that the folder wasn't
there again.

Help!  What am I doing wrong?  I'm missing something very simple, I'm
sure.  But it doesn't look like it works "out of the box".

You should use "nnfolder:archive" instead of "nnfolder".

And what piece of documentation would tell me that, and why doesn't
the other work?  If it's as broken as my short experiment showed, it
should be red-flagged in the docs.  Or just fixed.

"nnfolder" means the method of (nnfolder ""), while "nnfolder:archive"
is used for (nnfolder "archive").

That misses the issue again.

When I create a new NNML group, I type:

        G M
        random.group <RET>
        nnml <RET>

When I created this NNFOLDER group, I typed:

        G M
        random.group <RET>
        nnfolder <RET>

And nnfolder put it in the same directory space as the nnml groups,
and they both started duking it out.

It *doesn't* work out of the box.  Or if that's not the way I should
have used it, it *wasn't* red flagged as "you can't use THIS until
you set THAT and THAT OTHER THING".

I'm not an idiot.  But I broke things by trying to follow directions.
If you say the directions are in there, please point to them.

You should use seperate directories for the different backends. I've found out
the hard way too, a year back, and I don't think the docs tell you this. So,
you'll have to set

(setq nnfolder-directory "/home/name/Mail/nnfolder")
(setq nnml-directory "/home/name/Mail/nnml")

Is this a bug-report/feature-request on the manual?  If not, then can
it please be one?

I think the sections that show how to add a new mail backend should
"strongly recommend" specifying a directory (that's different from any
other directory).

How hard would it be to write code that checked for different backends
using the same directory, and throw an error if that happens?  (What I
mean is, somebody with more time than me please do it!)

Hm?  If you type `rm foo', do you expect the system to delete the file
`foo.c' instead?

When Gnus asks you for a server, and you enter the server name, why
should it choose a different server than the one you entered?

No, I expect it to delete "foo".

I did a G M of "arch.todo" and "nnfolder".  I expected this to create
an nnfolder thing "somewhere".  As it turns out, it creates it in the
same directory as my "nnml" did, and they can't tell from each other
who owns the directory.

Apparently the value for nnfolder-directory "out of the box" is the
same as the value for nnml-directory "out of the box", so the two
servers fight over the same named files and directories.  If it breaks
things, then it should either be disabled, or red-flagged.  I'm no
dummy, and I ended up creating some nasty overlaps.  How in the world
do you expect a *beginner* to get this?

How would it have occured to me to use "arch.todo" and "archive"
instead of "nnfolder", when I see "nnfolder" in the list of backends
for mail in the manual, and not "archive"?

Ah.  Right.  This is a problem.  I have tried to get the Powers That
Be to change the directories, but they raise the (valid) point that
this would stop existing Gnus installations from running.  Which is
bad.

Lars' suggestion was to have `server creation' wizards which
automatically offer different directories (or active files, at least)
as a default.

PS: Since `Lars' is pronounced like `lush' (I gather), does that mean
    I should have written "Lars's"?

Re: nnfolder has me baffled

[David S. Goldberg]

There was a thread about using multiple mail backends and multiple
servers of the same type within the last couple of months.  I thought
the general consensus was that having the default values of
nn*-directory etc was a bad thing precisely because of this problem.
I'm not sure there was consensus on what to do about it.

This is the right thing for Gnus to do, since it has two servers,
`nnfolder+archive' and `nnfolder', and you chose the second one.

This is because two of your backends (nnml and nnfolder) share the
same active file, and each gets confused by the other's groups.

You may wish to frob your nnfolder server to have a different active
file.  It might be best to locate your nnfolder server in a different
directory altogether, though I'm not sure if this is necessary.  (I
avoid multiple servers using the same directory :-)
