Deleting the .nnmaildir directories while Gnus is running would cause
problems.  Exit Gnus, then delete the "nov" and "num" directories in
all of your .nnmaildir directories.  (You can keep the "marks"
directories so you don't lose read/replied/etc. information.  The
problem is likely to be in "nov" or "num" anyway.)  Then start Gnus
again and see if anything still goes wrong.

Also note that deleting the "num" directories will make nnmaildir
reassign article number starting from 1.  This can cause problems if
you use the cache or agent, since they identify articles by number.
But if you've already caused damage by deleting the directories while
Gnus was running, then deleting the "num" directories again probably
won't do any more harm.

too late, i already deleted the whole .nnmaildir directories. alas, if
i knew,  i would have  kept the marks  directories, but, it  went this
way.

well,  after deleting  all .nnmaildir  dirs,  i still  got some  other
messages when  restarting gnus. i cannot  tell if it's  related to the
next problem:

if new  messages arrive while  a group is  visited, i cannot  see them
pressing / N  on the right summary; they appear as  already read, so i
can see them by pressing / O, but this is of course a problem.

if i close all groups and  then launch getmail, everything seems to go
fine.


my .gnus  configuration is  quite minimal, and  the only  reference to
nnmaildir is:

,----
| (setq gnus-select-method
|       '(nnmaildir "localhost"
|                   (directory "~/maildir")
|                   (expire-age never)))
`----


should i change anything?

thanks

You should still do what I described above.  That will ensure that the
damage won't grow any further.

It's probably because you deleted them while Gnus was running.  That
can cause damage that will persist to future Gnus sessions.

That looks ok.

i did, and it *almost*  worked: it solved all synchronization problems
but for the inbox folder: new messages to inbox folder still appear as
read, and sometimes they don't even appear; restarting gnus makes them
new again.


the inbox folder is just a  maildir folder as all other ones; the only
special thing i can  think of is the fact that i  often move or delete
messages from  there, so that the  apparent number of  messages is far
bigger than the real one. i could move all the messages to a temporary
folder and  then back again, to  change the article numbers,  but in a
couple of days they would be messed again anyway.


what can be the cause of this sync problem with inbox?

thanks

i tried the  above. i was not  able to move or delete  a message, that
is: i deleted it, but it was still there.

i closed gnus, and checked the  inbox maildir (with mutt and also with
find ~/maildir/inbox): it was empty.

i restarted gnus: the message was there.

i closed gnus, deleted .nov  and .num, restarted gnus. the message was
there.

so  i  unsubscribed inbox,  killed  inbox,  closed  gnus and  manually
deleted inbox.

i then restarted gnus, and inbox was gone.

then  i created  inbox  and the  subdirs  cur new  tmp, started  gnus,
pressed  F to find  the inbox  group, but  it didn't  find it  (it had
always worked for new groups before).


now i'm close to surrender.


the gnus info manual says that  one can copy an entire maildir tree to
another computer, and magically use that maildir tree in a new gnus.


of course, i have just one computer, so i'm tempted to delete ~/.newsrc*
and ~/News, try again, and if  it still doesn't work, pass to mutt and
try again gnus in a year or two.


can anybody save me? thanks

nnmaildir problems after upgrading to emacs 22.1.1

[Pietro Giorgianni]

[-- Attachment #1.1: Type: text/plain, Size: 5282 bytes --]

hi,

i use the  nnmaildir backend. mail is fetched  and splitted by getmail
and mailfilter.

everything worked fine, i  was using debian emacs-snapshot (22.0.95 or
the like) and No Gnus v0.7 (from cvs, updated to some months ago).

yesterday i installed debian emacs22 (22.1.1), which brings gnus 5.11.

when  i  first  runned  gnus  after  upgrading,  i  had  errors  about
.nnmaildir directories. i deleted some of them, and then i was able to
run gnus, but,  if i select a message from, say,  inbox, and move them
to another folder, i got the error.

if i  delete the  .nnmaildir directory, quit  gnus, exit  emacs, start
emacs again, run gnus, it then works (simply restarting gnus doesn't),
but it's annoying having to  loose all information about read, replied
etc. messages.

of course this happens just the first time i use a folder with the new
version.

here is the backtrace i receive.  i have replaced some parts with ...,
to eliminate unprintable chars and also personal data.


is this incompatibility documented somewhere?

is  it ok to  simply delete  the .nnmaildir  directories, or  should i
expect problems in the future?
