| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As we want to add an "informational" channel to the `Python Help: Available` category, we need to make sure that the Help Channel System ignores that channel. To do that, I've added an `is_excluded_channel` staticmethod that returns `True` if a channel is not a TextChannel or if it's in a special EXCLUDED_CHANNELS constant. This method is then used in the method that yields help channels from a category and in the `on_message` event listener that determines if a channel should be moved from `Available` to `Occupied`.

This is accomplished by using the "bulk channels update" endpoint of the Discord API. ----------- The Problem ----------- Discord's positioning system is not that easy to work with for developers: Instead of having separate pools of position integers for each category, all text channels are considered to be part of the same "position pool" (or "bucket" in discord.py terms). This also means that changing the position integer of one channel may cause the position integer of another to change, regardless of if the channels share a category or even of if they are close to each other in the guild. As clients receive the position update for each channel as separate CHANNEL UPDATE events, this means that moving one channel may cause other channels to (temporarily) jump around as the client receives the EVENTS from the API. As some position changes affect all the channels in the guild, this will also trigger a nice "channel wave" rolling down the channel list from time to time. For our use case, this was exacerbated by the way `discord.py` handles position changes: It will enumerate the entire, sorted channel list whenever a position change occurs and send a "bulk request" with updated position integers for the entire guild to Discord. This was the reason that all of the sorting methods we've tried resulted in a lot of those "wave" glitches as clients would get a lot of CHANNEL UPDATE events. In addition, the way `discord.py` inserted channels into the payload also meant that our "high integer" methods did not work reliably. ------------ The Solution ------------ Fortunately, there is a solution that will work well most of the time: Making a `bulk channels update` request with only channels of the category we're currently interested in. By providing the current position of the channels that are already in the category, combined with the correct position of the channel moving into the category, we effectively "lock in" the existing channels at the location they already have. The new channel is simply moved into the right position in relation to the existing channels. This means that effectively, we only communicate one channel position change to Discord, making sure that as few channels as possible actually change their formal "position int". From there on, there are two options: 1. Keep the existing channels in place, add the new channel at the bottom (new highest int) 2. Keep the existing channels in place, add the new channel at the top (new lowest int) Both methods work, but option two has a flaw: The position int will get smaller and smaller, until it reaches `0`. Since negative position integers are not allowed, the entire category now has to be shifted upwards to make room for new top channels. This comes at the cost of a "wave" glitch within the category. My initial instinct was to solve this by giving the channels in the category a "really high" straight of position ints, but as Discord recalculates the ints from time to time anyway, this does not work. That's why I opted for the `bottom sort` option, which does not suffer from that issue. I've also asked the question of `top` vs `bottom` in #admins, without the context above, and the preferred method seemed to be `bottom` in any case. ----------- Limitations ----------- While Discord doesn't care that much about duplicates or neatly ascending integers, some channel move actions will inevitably result in a recalculation of the positions ints. This means that "wave" glitches may still happen from time to time, but they should be infrequent. (They also happen if you drag channels in your client; it seems to be a fundamental part of how positioning works.) I think this is something we'll have to live with. Another thing that I suspect may happen is that during times of API lag in the middle of help channel rush hour, some CHANNEL UPDATE events belonging to previous channel moves will not be received/processed yet by the time we make the next move. As we rely on cached position integers, this could mean that from time to time a channel is inserted near the bottom but not at the bottom. As Discord sends these CHANNEL UPDATE replies as individual events in an asynchronous manner instead of as a single response to our `bulk channels update` request, there's nothing much we can do about this. However, I have yet to observe this, so maybe it will never happen.
