# Getops 2.3b

# $Id: getops.tcl,v 1.18 2003/03/26 00:19:30 wcc Exp $

# This script is used for bots to request and give ops to each other.
# For this to work, you'll need:

# - Bots must be linked in a botnet
# - Every bot that should be ops on your channels must load this script
# - Add all bots you wanna op with this one using the .+bot nick address
#   command. The "nick" should be exactly the botnet-nick of the other bot
# - Add the hostmasks that uniquely identify this bot on IRC
# - Add a global or channel +o flag on all bots to be opped
# - Do exactly the same on all other bots

# The security of this relies on the fact that the bot which wants to have
# ops must be 1) linked to the current botnet (which requires a password),
# 2) have an entry with +o on the bot that he wants ops from and 3) must match
# the hostmask that is stored on each bots userfile (so it is good to keep the
# hostmasks up-to-date).

# 2.3c by PPSlim <ppslim@ntlworld.com>
#  - Small fix on timer hanlding.
#    Not list formatted, allowing command parsing of channel name

# 2.3b by gregul <unknown>
#  - small fix in getbot

# 2.3a by guppy <guppy@eggheads.org>
#  - fix for bind need

# 2.3 by guppy <guppy@eggheads.org>
#  - minor cleanup to use some 1.6 tcl functions
#  - use bind need over need-op, need-invite, etc ...

# 2.2g by poptix <poptix@poptix.net>
#  - Fabian's 2.2e broke the script, fixed.

# 2.2f by Eule <eule@berlin.snafu.de>
#  - removed key work-around added in 2.2d as eggdrop now handles this
#    correctly.

# 2.2e by Fabian <fknittel@gmx.de>
#  - added support for !channels (so-called ID-channels), using chandname2name
#    functions. This makes it eggdrop 1.5+ specific.

# 2.2d by brainsick <brnsck@mail.earthlink.net>
#  - Undernet now handles keys differently.  It no longer gives the key on a
#    join, but instead gives it on an op, but eggdrop doesn't check for this.
#    getops-2.2d should now handle this correctly.  (This should be the final
#    fix to the key problems.)

# 2.2c by Progfou (Jean Christophe ANDRE <progfou@rumiko.info.unicaen.fr>)
#  - changed "Requested" to "Requesting" as it was a little confusing
#  - corrected the "I am not on chan..." problem with key request
#    (thanks to Kram |FL| and Gael for reporting it)
#  - removed more unnecessary check

# 2.2b by Progfou (Jean Christophe ANDRE <progfou@rumiko.info.unicaen.fr>)
#  - removed global +o in unknown bot test
#  - removed unnecessary checks due to previous unknown bot test

# 2.2a by Progfou (Jean Christophe ANDRE <progfou@rumiko.info.unicaen.fr>)
#  - removed Polish language!

# 2.2 by Cron (Arkadiusz Miskiewicz <misiek@zsz2.starachowice.pl>)
#  - works good (tested on eggdrop 1.3.11)
#  - asks from unknown (and bots without +bo) are ignored
#  - all messages in Polish language
#  - better response from script to users
#  - fixed several bugs

# 2.1 by Ernst
# - asks for ops right after joining the channel: no wait anymore
# - sets "need-op/need-invite/etc" config right after joining dynamic channels
# - fixed "You aren't +o" being replied when other bot isn't even on channel
# - better response from bots, in case something went wrong
#   (for example if bot is not recognized (hostmask) when asking for ops)
# - removed several no-more-used variables
# - added the information and description above

# 2.0.1 by beldin (1.3.x ONLY version)
# - actually, iso needed to be modded for 1.3 :P, and validchan is builtin
#   and I'll tidy a couple of functions up to

# 2.0 by DarkDruid
# - It'll work with dynamic channels(dan is a dork for making it not..)
# - It will also only ask one bot at a time for ops so there won't be any more
#   annoying mode floods, and it's more secure that way
# - I also took that annoying wallop and resynch stuff out :P
# - And I guess this will with with 1.3.x too

# Previously by The_O, dtM.
