[gnu.emacs.bug] rmail bug with labels

rig@THEORY.LCS.MIT.EDU (10/14/88)

rmail-next-labeled-message and rmail-previous-labeled-message aren't
working.  They claim not to be able to find any message with the
appropriate label.

I did 'emacs -q' and then I did what the dribble file below shows.
(How can you read these things?)

(rmail "~/emacs/rmail-bug.rmail")
afoo

That is, I did '(rmail "~/emacs/rmail-bug.rmail")'.  Then I did 'a'
and 'foo
the file.  Then I did p to move to the previous message.  Next, I did
'C-M-n' and 'foo
that happened was that I got the message (below the mode line) "No
following message with labels foo".  The rest of the dribble file is
just my exiting from emacs.

Interestingly, in another test, I found that 'C-M-l' followed by
'foo

The version of emacs I am running is
    GNU Emacs 18.50.8 of Sat Mar 26 1988 on allspice (berkeley-unix)
 I notice though that it says allspice which is presumably where the
code was copied from, but if this is supposed to be saying where it
is really running, it is on theory.  The same comment applies to the
last message I sent to bug-gnu-emacs@prep.

Another bug with rmail: 

Somehow, in version 18.50.6 running on a sun 3/75 a full disk seems to cause
rmail to lose incoming mail.  

I looked at the code for the get-new-mail function and it looks like it does
the "right thing" in terms of dealing with full disks, in that it tries to
catch errors during the saving of the emacs buffer.  My guess is that this
problem may be specific to nfs, in that it seems possible that the save
function can complete even though the actual writing of the file did not
happen (e.g. in the case where the disk is full).

Are others aware of this problem?  I would guess that it must affect other
things besides rmail, too.  Anyone have any suggestions for fixing it?

Thanks,

Hmm ... strange. I've not lost mail on full disk errors - and it happens to me
frequently (same version of emacs, too.).

Perhaps you have been lucky or your NFS configuration is different.  I
received two other confirmations of this happening from other people. 

In any case, be careful.
