[Jordi Mallach]

Hello, I got the following report against 0.6.90. Seems something we
want to see fixed in 0.7.

Package: mailutils
Version: 1:0.6.90-3
Severity: grave

I lost 20 hours of mail because of a disk full and a bug in movemail... :-(

I use Emacs/gnus to read my mail and I get it through ssh on a server that
launches /usr/bin/movemail.mailutils to get my mail from the local
/var/mail/keryell

Since ssh could also fail, I use movemail to move my mail first to an
archive directory and I use the whole in a more general 2-phase commit
scheme from Emacs with (file :prescript ... :postscript ... ).
Unfortunately, it appears that if the destination directory is full,
movemail creates a 0-sized destination file and keeps a 0-sized source
file... :-(

I used to use the movemail given from Emacs but since Emacs may not be
installed on the server, I've switched to movemail.mailutils.

To test the issue again in a simpler case, I used the RAM-disk I have on my
computer in /dev/shm.

# Full up the destination :
cp /dev/zero /dev/shm
df /dev/shm

So now I have lost the content of /var/mail/keryell...

I've try to investigate this issue but movemail.mailutils is far more
complex than the Emacs version with its object oriented paradigm to deal
all kind of formats...:-/

I've tried to recompile it from an apt-get source with -g option to track
down the bug with a debugger but the compilation fails :
make[3]: entrant dans le répertoire « 
/users/lit/keryell/tmp/mailutils-0.6.90/imap4d »
if gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../lib -I../include -I../mailbox 
-I../include/mailutils/gnu     -DSYSCONFDIR=\"/usr/local/etc\"  -g -O2 -MT 
fetch.o -MD -MP -MF ".deps/fetch.Tpo" -c -o fetch.o fetch.c; \
        then mv -f ".deps/fetch.Tpo" ".deps/fetch.Po"; else rm -f 
".deps/fetch.Tpo"; exit 1; fi
fetch.c:67: error: array type has incomplete element type
make[3]: *** [fetch.o] Erreur 1


Right now, I'm back on /usr/lib/xemacs-21.4.17/i386-debian-linux/movemail
on the server. :-)

By reading the Emacs version of movemail, it looks like this version is
more correct and the hard core test looks fine :

/usr/lib/emacs/22.0.50/i486-linux-gnu/movemail /var/mail/keryell 
/dev/shm/keryell
movemail: No space left on device for /dev/shm/keryell


Thank you for your time.
