Banned Names list ignored

i’ve been digging into the array that is being saved for the banned names in my network settings page. the serialized array being saved into the wp_sitemeta table contains only a single string value like this:

a:1:{i:0;s:50:”www web root admin main invite administrator files test1 test2 test3″;}

when it is saved this way it does not work. any of the banned names can be registered. but then when i manually go into the db and edit the array to contain multiple string values (like below) the banned names function works.

a:11:{i:0;s:3:”www”;i:1;s:3:”web”;i:2;s:4:”root”;i:3;s:4:”admin”;i:4;s:4:”main”;i:5;s:6:”invite”;i:6;s:13:”administrator”;i:7;s:5:”files”;i:8;s:5:”test1″;i:9;s:5:”test2″;i:10;s:5:”test3″;}

i have not dug into the code yet to isolate where this happens. this is also a widely used function and i haven’t seen the topic being raised elsewhere. i don’t know how it could be just me though. this is a test install of multisite. i have zero plugins & themes installed. i am running PHP version 5.2.9 and MySQL version 5.0.96-community.

if anyone has some insight i would greatly appreciate it. the last ticket i see in trac related to illegal_names & serializing was 4 months ago.

the next thing i’ll do is see if i can duplicate this in another multisite install. if someone is game to take a gander at their wp_sitemeta table and look at the illegal_names value and see what the array looks like, then test registering a banned name on it too, that would be great.

thanks

no, its an empty install for testing. no plugins installed nor activated. i also have a fresh xampp install doing the same thing.

thanks. i’ll submit a trac ticket this evening. 🙂 marking this resolved for now. will see what comes from trac.
