From 9b8d688657f7044ad27ff81f7eb7d50f7f593ed6 Mon Sep 17 00:00:00 2001 From: Akarys42 Date: Fri, 25 Oct 2019 12:10:26 +0200 Subject: Autodelete offensive messages after one week. If the filter cog filter a message that's considered as offensive (filter["offensive_msg"] is True), the cog create a new offensive message object in the bot db with a delete_date of one week after it was sent. A background task run every day, pull up a list of message to delete, find them back, and delete them. --- bot/cogs/filtering.py | 89 +++++++++++++++++++++++++++++++++++++++++++++------ 1 file changed, 79 insertions(+), 10 deletions(-) diff --git a/bot/cogs/filtering.py b/bot/cogs/filtering.py index 1d1d74e74..d1d28ac10 100644 --- a/bot/cogs/filtering.py +++ b/bot/cogs/filtering.py @@ -1,12 +1,15 @@ +import asyncio +import datetime import logging import re from typing import Optional, Union import discord.errors from dateutil.relativedelta import relativedelta -from discord import Colour, DMChannel, Member, Message, TextChannel +from discord import Colour, DMChannel, Member, Message, NotFound, TextChannel from discord.ext.commands import Bot, Cog +from bot.api import ResponseCodeError from bot.cogs.moderation import ModLog from bot.constants import ( Channels, Colours, DEBUG_MODE, @@ -16,13 +19,13 @@ from bot.constants import ( log = logging.getLogger(__name__) INVITE_RE = re.compile( - r"(?:discord(?:[\.,]|dot)gg|" # Could be discord.gg/ - r"discord(?:[\.,]|dot)com(?:\/|slash)invite|" # or discord.com/invite/ + r"(?:discord(?:[\.,]|dot)gg|" # Could be discord.gg/ + r"discord(?:[\.,]|dot)com(?:\/|slash)invite|" # or discord.com/invite/ r"discordapp(?:[\.,]|dot)com(?:\/|slash)invite|" # or discordapp.com/invite/ - r"discord(?:[\.,]|dot)me|" # or discord.me - r"discord(?:[\.,]|dot)io" # or discord.io. - r")(?:[\/]|slash)" # / or 'slash' - r"([a-zA-Z0-9]+)", # the invite code itself + r"discord(?:[\.,]|dot)me|" # or discord.me + r"discord(?:[\.,]|dot)io" # or discord.io. + r")(?:[\/]|slash)" # / or 'slash' + r"([a-zA-Z0-9]+)", # the invite code itself flags=re.IGNORECASE ) @@ -36,6 +39,8 @@ TOKEN_WATCHLIST_PATTERNS = [ re.compile(fr'{expression}', flags=re.IGNORECASE) for expression in Filter.token_watchlist ] +OFFENSIVE_MSG_DELETE_TIME = datetime.timedelta(days=7) # Time before an offensive msg is deleted. + class Filtering(Cog): """Filtering out invites, blacklisting domains, and warning us of certain regular expressions.""" @@ -54,7 +59,8 @@ class Filtering(Cog): "notification_msg": ( "Your post has been removed for abusing Unicode character rendering (aka Zalgo text).

Instead, they just contain the actual value added or removed. The code was incorrectly trying to access old and new values for the iterable changes. The iterable changes are only useful for the role diff, but they aren't even needed for that. The role diff calculation has been refactored to always get the diff rather than doing it only if it sees there has been a change to the `_roles` attribute. To be clear, `_roles` only has IDs, which is why its diff isn't that useful anyway. To use it, the code would have to get the Role objects, which is basically what the `roles` property already does. `_cs_roles` seems to be some Role object cache, but its reliability is unclear. --- bot/cogs/moderation/modlog.py | 42 ++++++++++++++++++++---------------------- 1 file changed, 20 insertions(+), 22 deletions(-) diff --git a/bot/cogs/moderation/modlog.py b/bot/cogs/moderation/modlog.py index 41472c64c..02396e1c5 100644 --- a/bot/cogs/moderation/modlog.py +++ b/bot/cogs/moderation/modlog.py @@ -452,6 +452,21 @@ class ModLog(Cog, name="ModLog"): channel_id=Channels.mod_log ) + @staticmethod + def get_role_diff(before: t.List[discord.Role], after: t.List[discord.Role]) -> t.List[str]: + """Return a list of strings describing the roles added and removed.""" + changes = [] + before_roles = set(before) + after_roles = set(after) + + for role in (before_roles -

The DurationDelta converter will allow the Slowmode cog to use a formatted timestamp instead of an integer representing seconds. I created a new converter because the Duration converter returned a datetime.datetime object, instead of a time delta. Joe mentioned that I could just subtract the datetime.datetime object from datetime.utcnow(), but there is a small delay between conversion and when the function is actually executed. This caused something like `!slowmode set #python-general 5s` to set the slowmode delay to 4 seconds instead of 5. Now, with this new converter, the set command can be invoked using a formatted timestamp like so: `!slowmode set #python-general 4h23M19s`. This would set the slowmode delay in #python-general to 4 hours, 23 minutes, and 19 seconds. Of course that delay would be quite overkill for #python-general, but that's just for the sake of this example. --- bot/cogs/slowmode.py | 31 +++++++++++++++++++++---------- bot/converters.py | 22 ++++++++++++++++++---- 2 files changed, 39 insertions(+), 14 deletions(-) diff --git a/bot/cogs/slowmode.py b/bot/cogs/slowmode.py index 7bbd61623..898f4bf52 100644 --- a/bot/cogs/slowmode.py +++ b/bot/cogs/slowmode.py @@ -1,11 +1,15 @@ import logging +from datetime import datetime +from dateutil.relativedelta import relativedelta from discord import TextChannel from discord.ext.commands import Cog, Context, group from bot.bot import Bot from bot.constants import Emojis, MODERATION_ROLES +from bot.converters import DurationDelta from bot.decorators import with_role +from bot.utils import time log = logging.getLogger(__name__) @@ -24,28 +28,35 @@ class Slowmode(Cog): @slowmode_group.command(name='get', aliases=['g']) async def get_slowmode(self, ctx: Context, channel: TextChannel) -> None: """Get the slowmode delay for a given text channel.""" - slowmode_delay = channel.slowmode_delay - await ctx.send(f'The slowmode delay for {channel.mention} is {slowmode_delay} seconds.') + delay = relativedelta(seconds=channel.slowmode_delay) + await ctx.send(f'The slowmode delay for {channel.mention} is {time.humanize_delta(delay, precision=3)}.') @slowmode_group.command(name='set', aliases=['s']) @with_role(*MODERATION_ROLES) - async def set_slowmode(self, ctx: Context, channel: TextChannel, seconds: int) -> None: + async def set_slowmode(self, ctx: Context, channel: TextChannel, delay: DurationDelta) -> None: """Set the slowmode delay for a given text channel.""" - if 0 <= seconds <= 21600: - await channel.edit(slowmode_delay=seconds) + # Convert `dateutil.relativedelta.relativedelta` to `datetime.timedelta` + # Must do this to get the delta in a particular unit of time + utcnow = datetime.utcnow() + slowmode_delay = (utcnow + delay - utcnow).seconds + + humanized_delay = time.humanize_delta(delay, precision=3) + + if 0 <= slowmode_delay <= 21600: + await channel.edit(slowmode_delay=slowmode_delay) await ctx.send( - f'{Emojis.check_mark} The slowmode delay for {channel.mention} is now {seconds} seconds.' + f'{Emojis.check_mark} The slowmode delay for {channel.mention} is now {humanized_delay}.' ) - log.info(f'{ctx.author} set the slowmode delay for #{channel} to {seconds} seconds.') + log.info(f'{ctx.author} set the slowmode delay for #{channel} to {humanized_delay}.') else: await ctx.send( - f'{Emojis.cross_mark} The slowmode delay must be between 0 and 21600 seconds.' + f'{Emojis.cross_mark} The slowmode delay must be between 0 and 6 hours.' ) log.info( - f'{ctx.author} tried to set the slowmode delay of #{channel} to {seconds} seconds, ' - 'which is not between 0 and 21600 seconds.' + f'{ctx.author} tried to set the slowmode delay of #{channel} to {humanized_delay}, ' + 'which is not between 0 and 6 hours.' ) @slowmode_group.command(name='reset', aliases=['r']) diff --git a/bot/converters.py b/bot/converters.py index 4deb59f87..65963f513 100644 --- a/bot/converters.py +++ b/bot/converters.py @@ -181,8 +181,8 @@ class TagContentConverter(Converter): return tag_content -class Duration(Converter): - """Convert duration strings into UTC datetime.datetime objects.""" +class DurationDelta(Converter): + """Convert duration strings into dateutil.relativedelta.relativedelta objects.""" duration_parser = re.compile( r"((?P\d+?) ?(years|year|Y|y) ?)?" @@ -194,9 +194,9 @@ class Duration(Converter): r"((?P\d+?) ?(seconds|second|S|s))?" ) - async def convert(self, ctx: Context, duration: str) -> datetime: + async def convert(self, ctx: Context, duration: str) -> relativedelta: """ - Converts a `duration` string to a datetime object that's `duration` in the future. + Converts a `duration` string to a relativedelta object.

When we're using the !reply command, using a regular UserConverter is somewhat problematic. For example, if I wanted to send the message "lemon loves you", then I'd try to write `!reply lemon loves you` - however, the optional User converter would then try to convert `lemon` into a User, which it would successfully do since there's like 60 lemons on our server. As a result, the message "loves you" would be sent to a user called lemon.. god knows which one. To solve this bit of ambiguity, I introduce a new converter which only converts user mentions or user IDs into User, not strings that may be intended as part of the message you are sending. https://github.com/python-discord/bot/issues/1041 --- bot/cogs/dm_relay.py | 3 ++- bot/converters.py | 22 ++++++++++++++++++++++ 2 files changed, 24 insertions(+), 1 deletion(-) diff --git a/bot/cogs/dm_relay.py b/bot/cogs/dm_relay.py index 0c3eddf42..c5a3dba22 100644 --- a/bot/cogs/dm_relay.py +++ b/bot/cogs/dm_relay.py @@ -8,6 +8,7 @@ from discord.ext.commands import Cog from bot import constants from bot.bot import Bot +from bot.converters import UserMentionOrID from bot.utils import RedisCache from bot.utils.checks import in_whitelist_check, with_role_check from bot.utils.messages import send_attachments @@ -29,7 +30,7 @@ class DMRelay(Cog): self.bot.loop.create_task(self.fetch_webhook()) @commands.command(aliases=("reply",)) - async def send_dm(self, ctx: commands.Context, member: Optional[discord.Member], *, message: str) -> None: + async def send_dm(self, ctx: commands.Context, member: Optional[UserMentionOrID], *, message: str) -> None: """ Allows you to send a DM to a user from the bot. diff --git a/bot/converters.py b/bot/converters.py index 898822165..7c62f92dd 100644 --- a/bot/converters.py +++ b/bot/converters.py @@ -330,6 +330,28 @@ def proxy_user(user_id: str) -> discord.Object: return user +class UserMentionOrID(UserConverter): + """ + Converts to a `discord.User`, but only if a mention or userID is provided. + + Unlike the default `UserConverter`, it does allow conversion from name, or name#descrim. + + This is useful in cases where that lookup strategy would lead to ambiguity. + """ + + async def convert(self, ctx: Context, argument: str) -> discord.User: + """Convert the `arg` to a `discord.User`.""" + print(argument) + match = self._get_id_match(argument) or re.match(r'<@!?([0-9]+)>$', argument) + + print(match) + + if match is not None: + return await super().convert(ctx, argument) + else: + raise BadArgument(f"`{argument}` is not a User mention or a User ID.") + + class FetchedUser(UserConverter): """ Converts to a `discord.User` or, if it fails, a `discord.Object`. -- cgit v1.2.3 From 80c1dbb240b744ceed5d1ea56c44c91d0014c304 Mon Sep 17 00:00:00 2001 From: Leon Sandøy Date: Wed, 15 Jul 2020 10:44:11 +0200 Subject: How did that except except block get in?

They do this to allow multiple instances of a cog to be used. If the Command class doesn't inherently support the `root_aliases` kwarg, it won't end up being copied when a command gets copied. `Command.__original_kwargs__` could be updated to include the new kwarg. However, updating it and adding the attribute to the command wouldn't be as elegant as passing a `Command` subclass as a `cls` attribute to the `commands.command` decorator.

As that happens frequently with the burst_shared filter, it means that our bot joins in and starts spamming the channel with error messages. Another issue is that burst_shared may cause our bot to send a lot of DMs to a lot of different members. This caused our bot to get a DM ban from Discord after a recent `everyone` ping incident. I've decided to disable the `burst_shared` filter by commenting out the relevant lines but leave the code in place otherwise. This means we still have the implementation handy in case we want to re-enable it on short notice.
