Hi Aki,
I'm not sure if this bug was worked on? Sadly I ran into it too
recently, on version 2.3.4.1.

Hi!
Thank you for reporting this issue. We'll look into it. Maybe you can
use sqlite3 instead as workaround?

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

DICT_ITERATE_FLAG_RECURSE) == 0)

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
