I am trying to create a plugin that adds a new IMAP capability. So far I have this:
const char *foo_plugin_version = DOVECOT_ABI_VERSION;
static struct module *foo_module; static imap_client_created_func_t *next_hook_client_created;
static void foo_client_created(struct client **client) { str_append((*client)->capability_string, " XFOO");
if (next_hook_client_created != NULL) {
next_hook_client_created(client);
}}
void foo_plugin_init(struct module *module) { i_info(“init”); foo_module = module; next_hook_client_created = imap_client_created_hook_set(foo_client_created); }
void foo_plugin_deinit(void) { i_info(“deinit”); imap_client_created_hook_set(next_hook_client_created); }
const char foo_plugin_binary_dependency[] = "imap”;
On Fedora 20, with the dovecot and dovecot-devel packages installed, I compile this with:
cc -Wall -shared -fPIC -DHAVE_CONFIG_H -I/usr/include/dovecot -o lib20_foo_plugin.so foo-plugin.c
And then install with:
sudo cp lib20_foo_plugin.so /usr/lib64/dovecot/
(I also have mail_plugin_dir = /usr/lib64/dovecot in 10-mail.conf)
I enable this plugin in /etc/dovecot/conf.d/20-imap.conf with:
protocol imap { mail_plugins = $mail_plugins foo }
But … nothing happens. No warnings, no errors, no crashes.
How do I debug this? Am I missing something obvious?
Does the naming of the plugin matter?
