Bug was caused to the shallow copy not copying over the VoiceState
information embedded into the copy. This would mean that when the event
is called, before and after voice state information is essentially
equivalent.
The solution to fix this is to also copy the VoiceState objects.
The way the command cooldown works is using a windowed way of doing it.
That is, if we have a cooldown of 2 commands every 30 seconds then if we
do a single command, we have 30 seconds to do the second command or else
we will get rate limited. This more or less matches the common
expectations on how cooldowns should be.
These cooldowns can be bucketed up to a single dimension of depth for
a per-user, per-guild, or per-channel basis. Of course, a global bucket
is also provided. These cannot be mixed, e.g. no per-channel per-user
cooldowns.
When a command cooldown is triggered, the error handlers will receive a
an exception of type CommandOnCooldown with proper information regarding
the cooldown such as retry_after and the bucket information itself.
This is for exceptions that are inherently based on user errors and not
permission based. e.g. passing incorrect number of arguments, too many
arguments, or an invalid argument. CommandNotFound is not classified
under this since it isn't inherently a user input error in all cases.
Some invalid commands can simply be due to an odd bot prefix. It would
also diminish the usefulness of the new parent class if CommandNotFound
was included.
This change allows users to more easily create their own formatters
without having to reinvent the pagination logic themselves. Hopefully
this makes it less of a pain for people to create custom help pages.
This was a two-fold problem. The first of which involved the overwriting
of members during a GUILD_SYNC. Since we are requesting a chunk anyway,
we have all the member references we need without actually chunking. The
second problem came from the order. We were doing a GUILD_SYNC and then
doing the chunking requests. We should do the GUILD_SYNC after the
chunking in order to just update presences.
