Package: libmail-box-perl
Version: 2.055-1
Severity: important
Under certain conditions (see below), Mail::Box creates a folder lock
file called -- in the current directory. This is not only completely
useless, but it also fails to remove it if the current working dir is
changed between folder open and close (since it tries to remove "./--").
I'm aware that the documentation says that you _must_ specify a lockfile
name. However, if I do not give a full pathname, it is still interpreted
relative to the current dir, resulting in a "cannot unlink" message when
the folder is closed.
How to reproduce:=20
my $mgr =3D Mail::Box::Manager->new;
my $folder =3D $mgr->open(folder =3D> $filename,
access =3D> "rw",
lock_file =3D> "mylock",
lock_type =3D> "Multi");
Suggestions:=20
a) produce an error during folder open if the lock file name is
still "--" to protect against the missing lock_file option.
b) convert the name into a full path before creating the lock file.

This looks like the documented behavior - What I get from running your
example on a maildir is:
No locking possible for maildir folders. at /home/gwolf/cvs/pkg-perl/packages/libmail-box-perl/trunk/lib//Mail/Box/Manager.pm line 253
(in cleanup) Can't call method "unlock" on an undefined value at /home/gwolf/cvs/pkg-perl/packages/libmail-box-perl/trunk/lib//Mail/Box.pm line 366.
But if I am working on a mbox folder, I get no error messages. Now, as
explained in the Mail::Box::Maildir man page, maildir does not provide
any locking mechanisms:
lock_file L<Mail::Box> <not used>
lock_timeout L<Mail::Box> <not used>
lock_type L<Mail::Box> C<'NONE'> (constant)
lock_wait L<Mail::Box> <not used>
locker L<Mail::Box> undef
...I am closing this bug, as it is just acting as documented. If I
misunderstood it, feel free to re-open it.
