Stumbled into bug in Make group process

Stumbled into bug in Make group process

[Harry Putnam]

Running CVS 5.8.4  several weeks old
fsf emacs-20.5

While making groups in gnus I've stumbled onto a small bug or at least
something that seems it should behave differently:

To reproduce try this:

In group buffer use `G f' (nndoc) to make a spool style group of a
spool file.  In my case I used /var/spool/mail/reader 

Access the group then `M P a' to process mark it all.
Then `B c' to copy messages to a new gnus-owned nnfolder group.

That is: Answer the gnus prompt as to group name with:

nnfolder:NEWGROUP

Then press "F".. Gnus displays an inaccessable  *"nnml"* group
(nnml:NEWGROUP).

To get the nnfolder group I requested to display I had to:

`G m' NEWGROUP <RET>
Backend? nnfolder <RET>

And "nnfolder:NEWGROUP" is displayed.

I'm unable to reproduce this.  Gnus creates an nnfolder group when I
do this...

It does here too... but diplays a fictitious nnml group of the same
name, instead of displaying the nnfolder group.  The nnfolder group is
in fact created, but will only display by 'G m' NEWGROUP <RET> nnfolder <RET>.

I have (setq gnus-secondary-select-methods '((nnml "")))

Will that cause  the above reported behavior?  Should that be a list
that includes "nnfolder".... what is the syntax?

What other setting may affect this?

I have two more nnml servers that are only declared in Server Buffer
not in .gnus.

So in .gnus  I have  nnml ""

in Server buffer:

nnml ""
nnml "mail2"
nnml "n2m"

This sounds like you have an nnml server and a nnfolder server that
share the same active file, which is broken.

How can you copy messages to an nnfolder server that doesn't exist?
Hm.  Or does the server buffer contain more servers than you show here?

Yes...

     {nnfolder:archive} (opened)
     {nnml:mail2} (opened)
     {nnml:n2m} (opened)
     {nndir:~/spool/backup/} (opened)
     {nndir:~/spool/ping/} (opened)
     {nndraft:} (opened)
     {nnml:} (opened)
     {nntp:enews.newsguy.com} (opened)

Kai, as you often do, you've nailed the mistake I was making:  I do
have an nnfolder server as posted in reply to your question:

     {nnfolder:archive} (opened)
     {nnml:mail2} (opened)
     {nnml:n2m} (opened)
     {nndir:~/spool/backup/} (opened)
     {nndir:~/spool/ping/} (opened)
     {nndraft:} (opened)
     {nnml:} (opened)
     {nntp:enews.newsguy.com} (opened)

My mistake was copying mail to an (as yet unformed) group called
nnfolder:NEWGROUP.

I should have been sending to the proper server by copying to:
nnfolder+archive:NEWGROUP.

That works as expected.
Sorry about the static bandwidth...

Good guess... that was it.  Also my nnfolder server is nnfolder+archive:

So I was sending to a non-existent nnfolder server called nnfolder:NEWGROUP

Instead of nnfolder+archive:NEWGROUP.  Thanks for the tips.  The later
keeps the active files in order.

I wouldn't say it's a mistake.  IMVHO, Gnus should prevent you from
copying to a non-existing server.

It's nice that Gnus creates non-existing groups for you, but I think
this is not necessary for non-existing servers.

Lars?

Yes, I agree that that's a bug.
