Following typescript shows a minor bug in maildirmake. When trying to
create a new maildir with quota, maildirmake hangs without error
message. Creating without quota and establishing the quota immediately
afterwards works fine.

root@pop3:~# maildirmake -q 1000S test
^C

Hello, Courier users

Today the above problem was reported (Debian bug #214911) and I verified it
with maildirmake from Courier 0.42.2.

strace shows maildirmake running in a loop (below is one sample pass):

time([1065701758])                      = 1065701758
getpid()                                = 27705
stat64(0x804e2b0, 0xbffff4bc)           = -1 ENOENT (No such file or directory)
open("./test/tmp/1065701758.27705_NeWmAiLdIrSiZe.coldhand", O_RDWR|O_NONBLOCK|O_APPEND|O_CREAT, 0644) = -1 ENOENT (No such file or directory)
rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0
rt_sigaction(SIGCHLD, NULL, {SIG_DFL}, 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
nanosleep({3, 0}, {3, 0})               = 0

Can someone please tell me how to fix this problem ?

Bye

Hi,

I still experience this in current Courier, 0.60.0-2. I actually think the
problem is a bit wider: maildirmake also hangs on a Maildir that doesn't
have the 'tmp' subdir.

I have a script that uses maildirmake and it keeps hanging forever on a
damaged Maildir that somehow lost tmp/. It should rather generate a proper
error message instead, or restore tmp/.

I think the issue in the original report is most probably the same: the
quota function is tried before the tmp/ subdir is created.


cheers,
Thijs

Hi,

This is a minor bug report but an reasonable one to be fixed.

As reported originally by Alexander Koch in 2003:

| root@pop3:~#

It's annoying since it hangs without any error message.

I checked this issue with the latest maildrop 2.9.3 package, this is
true.  Checking the current source tree, "maildirmake -q 1000S test" is
not checking the existence of maildir and doing the same as
"maildirquota  -q 1000S test"... No wonder.

Why not check the existence of the maildir first and if it doesn't
exist, let's create it before setting the quota.
