[Dovecot] stats plugin + UID command continuation

When using the stats plugin for dovecot-2.0, UID commands that "continue" cause infinite recursion and crash. For example, "A22 UID FETCH 151 BODY[]" when the body is 3MB or so always crashes. For smaller messages, this command logs the duration twice. Here is a patch to fix it: --- stats-plugin.c.orig 2010-10-26 20:18:13.000000000 -0500 +++ stats-plugin.c 2010-10-26 20:19:10.000000000 -0500 @@ -197,6 +197,9 @@ commands = array_get_modifiable(&imap_commands, &count); for (i = 0; i < count; i++) { + if (strcasecmp(commands[i].name, "UID") == 0) + continue; + hash_table_insert(orig_cmds, (char *)commands[i].name, commands[i].func); commands[i].func = stats_command;
