bot: rate limit effects are no longer logged

[dgw]

The old code path for calling plugin callables (bot.call()) had some nice logging that kicked in if a rate limit was applied:

sopel/sopel/bot.py

Lines 728 to 756 in da05822

	if not trigger.admin and not func.unblockable:
	if func in self._times[nick]:
	usertimediff = current_time - self._times[nick][func]
	if func.user_rate > 0 and usertimediff < func.user_rate:
	LOGGER.info(
	"%s prevented from using %s in %s due to user limit: %d < %d",
	trigger.nick, func.__name__, trigger.sender, usertimediff,
	func.user_rate
	)
	return
	if func in self._times[self.nick]:
	globaltimediff = current_time - self._times[self.nick][func]
	if func.global_rate > 0 and globaltimediff < func.global_rate:
	LOGGER.info(
	"%s prevented from using %s in %s due to global limit: %d < %d",
	trigger.nick, func.__name__, trigger.sender, globaltimediff,
	func.global_rate
	)
	return
	if not trigger.is_privmsg and func in self._times[trigger.sender]:
	chantimediff = current_time - self._times[trigger.sender][func]
	if func.channel_rate > 0 and chantimediff < func.channel_rate:
	LOGGER.info(
	"%s prevented from using %s in %s due to channel limit: %d < %d",
	trigger.nick, func.__name__, trigger.sender, chantimediff,
	func.channel_rate
	)
	return

This code path still gets used by coretasks.handle_url_callbacks(), but that's the only remaining use of this method that I could find.

It would be helpful for future debugging, I think, if the bot.call_rule() code path had something like this. Right now it just sends a notice if the rate limit has a message, else it just silently returns without doing anything:

sopel/sopel/bot.py

Lines 666 to 670 in da05822

	limited, limit_msg = self.rate_limit_info(rule, trigger)
	if limit_msg:
	sopel.notice(limit_msg, destination=nick)
	if limited:
	return

Would be nice to have in the logs (INFO or DEBUG, either works) which rate limit was applied, in case there's some confusion during plugin dev.
