putlog "badwhois v$bwhois(version) loaded.." |
It's work Great, but not work with [nick...]
ex:
BOT on #chan1 have blacklist for #chan2
when nick on #chan2 join #chan1 he will get banned and kick
but when nick change nick to [nick] BOT not respon
and then when [nick] change nick to nick again BOT never respond anymore
Any can solve this? thx.

I hav'nt looked through that script yet, but generally;
If a script starts behaving oddly or stop responding when you use a nick with [] in the name, unload that script instantly as there is a great chance the script has a remote code exploit within it (just try using the nick [die]).
I'd strongly suggest you stop using this script until anyone can confirm it does not suffer from such an exploit.

| There are no [split] commands that would make the script tcl-special-char safe, so yeah, it's gonna choke on {} [] " \ and other such chars in names. |

[split] is a prerequisite for not choking on special chars
safety - or rather script security - is another matter which requires awareness of double evaluation

Safety and security are 2 different things in software engineering as I've read and learned; safety is about the safety of the surrounding environment (harm) while security is about the software being able to protect itself from accidental or deliberate intrusion.

yes, remove it as it's obsolete. it should be removed from TCL Archive as well (if it's there). I no longer have nor the time nor the mood on continuing this... so I'll just hang around from time to time (as if someone would care, anyway).

I care! if you leave, there will be no oldtimers left anymore (except slennox that is) which would be sad
