This allows users to check whether or not the permissions for a Guild Channel are synced with the permissions for its category. Discord automatically syncs the permissions when the overwrites are equal so just checking if the two overwrites are equal will determine if they are synced.
rename reverse -> oldest_first, which is more obvious what it does.
Then, honor it entirely - if you specify no `after` endpoint, we default
to the beginning of message history, similar to how `before` defaults to
the end of message history.
This is a breaking change, and will change the behavior of any iterator
that previously would have been returning messages in a weird order for
limits over 100
`for msg in history(reversed=True, limit=300)` would return the newest
300 messages, in a messed up order (100..0, 200..100, 300..200).
`for msg in history(oldest_first=True, limit=300)` will now return the
oldest 300 messages in order. And so on.
`for msg in history(after=msg)` is unchanged, this previously would
return the oldest 100 messages after `msg`, oldest->newest order, and
still will.
Use bare raise statement when reraising the exception that occured, and
remove unused exception variables. Also remove a pointless exception
handler in discord.opus.
Introduce a new internal type, SnowflakeList, which has better memory
footprint over a regular list or set of roles. It is suspected that
there will be a 9x reduction of memory for every Emoji instance and a
48 byte saving per Member instance. However, these savings will
probably only be evident on larger bots.
As a consequence of this change, Member.roles is now computed lazily.
Currently I am not sure if I want to do the initial sorting on the
SnowflakeList for Member, as this comes with a O(n log n) cost when
creating a Member for little purpose since SnowflakeList.has is not
overly relied on. If CPU time becomes an issue this might change.
This adds the following APIs:
* Guild.get_role
This removes the following APIs:
* Guild.role_hierarchy
To compensate for the removed APIs, Guild.roles is now a sorted list
based on hierarchy. The first element will always be the @everyone
role.
This speeds up access at the cost of some memory, theoretically.
This adds:
* CategoryChannel, which represents a category
* Guild.by_category() which traverses the channels grouping by category
* Guild.categories to get a list of categories
* abc.GuildChannel.category to get the category a channel belongs to
* sync_permissions keyword argument to abc.GuildChannel.edit to sync
permissions with a pre-existing or new category
* category keyword argument to abc.GuildChannel.edit to move a channel
to a category
In Discord, if the @everyone role has an explicit allow but a later
role has an explicit deny, the permission is denied rather than allowed
despite the fact that on Discord, allows have a higher priority than
denies.
This is because the @everyone role is supposed to be the first role to
be applied, while the rest could be applied in an aggregate fashion.
Fixes#630.
