BUG: panic when using fs:posix as dict for acl_shared_dict
Hi,
I'm using Dovecot 2.2.33.2 on a RHEL 7, new installation. When I use
fs:posix as dict for acl_shared_dict, like in Dovecot wiki
(https://wiki.dovecot.org/SharedMailboxes/ClusterSetup), doveadm-server
crash with error:
# doveadm acl set -u USERNAME FOLDER user=DEST_USERNAME lookup read
write-seen
doveadm(USERNAME): Panic: file dict-fs.c: line 127
(fs_dict_iterate_init): assertion failed: ((flags &
DICT_ITERATE_FLAG_RECURSE) == 0)
doveadm(USERNAME): Error: Raw backtrace:

Aborted
Attached coredump and configuration.
I'm not a programmer, but seems that assert is raised by
'fs_dict_iterate_init' function inside
'src/lib-dict-extra/dict-fs.c':
static struct dict_iterate_context *
fs_dict_iterate_init(struct dict *_dict, const char *const *paths,
enum dict_iterate_flags flags)
{
...
/* these flags are not supported for now */
i_assert((flags & DICT_ITERATE_FLAG_RECURSE) == 0);
...
because it is called by 'acl_lookup_dict_iterate_read' function in file
'src/plugins/acl/acl-lookup-dict.c'
static void acl_lookup_dict_iterate_read(struct acl_lookup_dict_iter *iter)
{
...
dict_iter = dict_iterate_init(iter->dict->dict, prefix,
DICT_ITERATE_FLAG_RECURSE);
...
with DICT_ITERATE_FLAG_RECURSE set.
Same problem also with Dovecot 2.3.0.
Thanks,
Marco
