Hello,
I have an issue with debug logging when using a custom plugin for Dovecot. In my plugin, I create a child event of the session's user event:
struct event *plugin_event = event_create(list->ns->user->event);
event_set_name(plugin_event, "oidc_shared_mailboxes_plugin");
event_set_min_log_level(plugin_event, LOG_TYPE_WARNING);
event_set_append_log_prefix(plugin_event, "oidc-shared-mailboxes-plugin: ");

I then use passthrough events like the following:
e_debug(event_create_passthrough(data->event)->event(), "Modified mailbox_list_iter_init was called.");
e_warning(event_create_passthrough(event)->event(), "Did not find required key 'roles' in the JWT body.");

e_warning and e_error work fine.
If I understand the documentation for the unified event filtering (https://doc.dovecot.org/configuration_manual/event_filter/#unified-filter-la...) correctly, I should be able to enable debug logging for with log_debug = event="oidc_shared_mailboxes_plugin". However, this setting has no influence on the logging behavior. The setting I have to set for the debug logging to work is mail_debug = yes (I do not have to set log_debug at all).
Is this intended behavior or am I doing something wrong?
Best regards,

Here is the output of dovecot -n (I removed the passdb, userdb, namespace, service, and managesieve settings as they cluttered the output):

Hi!
Usually this is used like this:
const struct event_category cat_oidc = {
.name = "oidc"
};
struct event *plugin_event = event_create(list->ns->user->event);
event_add_category(plugin_event, &cat_oid);
event_set_append_log_prefix(plugin_event, "oidc-shared-mailboxes-plugin: ")
...
e_debug(plugin_event, "foo");
e_warning(plugin_event, "bar");
now you can do
log_debug = category=oidc
