README

Hiatus, Unsupported Versions, Rate Limiting & Self Hosting

The creator of this bot is on an extended break, with no ETA to return to this project.

The below instructions are kept as a guide for existing installs. The share community version of the bot is rate limited. It sometimes works and sometimes doesn't.

Using the shared community version of this bot is no longer supported and not recommended.

Self-Hosting the bot (via Azure, AWS, Oracle Cloud, Docker instances) is provided via the Discord as a best effort process, but the underlying code is no longer being actively maintained. This message will be removed when this is no longer the case

AutoDelete

retention policies for 'gamers'

AutoDelete is a Discord bot that will automatically delete messages from a designated channel.

Messages are deleted on a "rolling" basis -- if you set a 24-hour live time, each message will be deleted 24 hours after it is posted (as opposed to all messages being deleted every 24 hours).

If you have an urgent message about the operation of the bot, say @AutoDelete adminhelp ... your message here ... and I'll get back to you as soon as I see it.

Add it to your server here: https://autodelete.riking.org/discord_auto_delete/oauth/start

Support me on Patreon if you enjoy the bot or to help keep it running! https://www.patreon.com/riking

Announcements server: https://discord.gg/FUGn8yE

Usage

Create a new "purged" channel where messages will automatically be deleted. Someone with MANAGE_MESSAGES permission (usually an admin) needs to say @AutoDelete start 100 24h to start the bot and tell it which channel you are using.

The 100 in the start command is the maximum number of live messages in the channel before the oldest is deleted. The 24h is a duration after which every message will be deleted. Acceptable units are h for hours, m for minutes, s for seconds. Warning: Durations of a day or longer still need to be specified in hours.

Make sure to mention the bot user and not the role alias!

A "voice-text" channel might want a shorter duration, e.g. 30m or 10m, when you just want "immediate" chat with no memory.

The bot must have permission to read (obviously) and send messages in the channel you are using, in addition to the Manage Messages permission. If the bot is missing permissions, it will disable itself and attempt to tell you, though this usually won't work when it can't send messages.

To turn off the bot, use @AutoDelete set 0 to turn off auto-deletion.

For a quick reminder of these rules, just say @AutoDelete help.

If you need extra help, say @AutoDelete adminhelp ... message ... to send a message to the support guild.

Deployment

Custom

See the docs directory for setup scripts and the configuration files that run the official bot instance.

Docker

How to build the docker containers:

docker build -t myimages/autodelete:tag .

Pre-built docker containers have been uploaded by the community to https://hub.docker.com/ if you wish to use them. These image owners should also be contactable over the support Discord server.

Required Mounts:

/path/to/storage/config.yml:/autodelete/config.yml
/path/to/storage/data/:/autodelete/data/

Example:

docker run -d -p 2202:2202/tcp \
 --name Autodelete \
 -v /opt/AutoDelete/config.yml:/autodelete/config.yml \
 -v /opt/AutoDelete/data/:/autodelete/data/ \
 --restart=always \
 myimages/autodelete:tag

Policy

The following two sections apply only to the hosted, community instance that can be invited to your server at the link above, as well as the help server and this GitHub repository.

Any changes to the following policies will be announced on the support server in the #announce channel.

Privacy

The following section is a DRAFT and may be incomplete and is subject to change, though the information present is correct to the best of my knowledge.

No message content is ever retained, except in the case when a message "@-mentions" the bot, where it may be retained to provide support or improve the bot. The "adminhelp" command transmits the provided message content to a channel in Discord and is subject to Discord's retention policies. Deleting a command invocation via the Discord interface has no effect on how long the bot's information about the invocation is stored.

The "community instance" of the bot will retain operational usage data, including data that identifies a particular guild or channel ID and/or with high-resolution timestamps. The full form of this data will be retained for 45 days (cite), and aggregated or summarized forms will be retained for up to 1.5 years. Usage data will not be used for commercial purposes except for the purpose of encouraging people to financially support the bot in a non-automated manner (in particular, usage data will not be sold or provided to any third party).

In order to faciliate product support, and response and detection of violations of the Acceptable Use Policy, an automated scan of your Guild structure will be performed and a report produced, with a focus on users and roles carrying the Manage Messages permission and channels where the bot is or was active. These reports may be shared with a limited audience to the extent necessary to identify or cure violations of the Acceptable Use Policy.

Contact Riking via the announcements server if you would like to request a copy of this data under the GDPR or equivalent consumer rights legislation.

The settings for a channel are kept on disk with the channel ID, guild ID, pinned message IDs, pin version timestamp, and time / count settings together. In the case that a channel is removed from the bot, either through set 0 or kicking the bot from the server, these settings are deleted. Backup or archival copies of the settings may be retained indefinitely but will not be used except for the purposes of disaster recovery.

Acceptable Use

The bot may not be used to perform or to assist with any of the following actions:

  • improperly use support channels to make false reports;
  • engage in conduct that is fraudulent or illegal;
  • generally, to cover up, hide, or perform any violation of the Discord Terms of Service;
  • to cause the bot to violate the Discord Terms of Service if it would not have violated those terms without your actions;
  • strain the technical infrastructure of the bot with an unreasonable volume or rate of requests, or requests designed to create an unreasonable load, except with explicit permission to conduct a specific technical or security test;
  • any use of the bot in a role where malfunction, improper operation, or normal operation of the bot could cause damages that exceed the greater of (a) $100 US Dollars or (b) the amount you have paid to the Operator of the bot;

Violations of the Acceptable Use Policy may be dealt with in one or more of the following manners:

  • An informal warning from the Operator, sent via the help server, via Discord DM, or from the bot's account through Discord.
  • A formal warning from the Operator, sent from the bot's account through Discord.
  • Removal of service from your guild, with or without warning.
  • Refusal of service to any guilds a particular user operates or has moderation capabilities on.
  • Referral of incident details to Discord, law enforcement, or other competent authorities.
  • Cooperating with investigations by Discord, law enforcement, or other competent authorities.

While the above list of remedies is generally ordered by severity, the Operator has no obligation to respect the ordering of the list, to enact any specific remedy, or to take action against any specific violation. Lack of action in response to a violation is not a waiver against future remedial action (in particular, note limited investigational capacity).

If you cannot comply with the Acceptable Use Policy, you must download the code of the bot and run it on your own infrastructure, accepting all responsibility for your actions.

Limitation of Liability

Under no circumstance will Operators's total liability arising from your use of the service exceed the greater of (a) the amount of fees Operator received from you or (b) $100 US dollars. This includes consequential, incidential, special, punitive, or indirect damages, based on any legal theory, even if the side liable is advised that the other may suffer damages, and even if You paid no fees at all. Some jurisdictions do not allow the exclusion of implied warranties or limitation of liability for incidental or consequential damages. In these jurisdictions, Operator's liability will be limited to the greatest extent permitted by law.

The service is provided to you without obligation of payment, and it is your responsibility to take actions to account for potentially harmful actions it may perform.

type LoadQOS 

type LoadQOS int8

Quality of service for the load queues. Lower numbers are higher priority.

The reuse of the reap queue for backlog load ordering is a hack - this should really be an ordered list of FIFO queues - but it's easier to just reuse the code. Plus, we get "wait until timestamp" for QOSLoadError for "free". 

const (
	QOSInteractive         LoadQOS = iota // Modify command
	QOSNewMessage                         // Saw message in channel
	QOSInitNoPins                         // Bot start events
	QOSLargeDelete                        // Deleted >25 messages
	QOSSingleMessageDelete                // Saw extremely old messages
	QOSInitWithPins                       // Start event with LPTS
	QOSLoadError                          // Previous attempt error

	QOSInvalid
	QOSInit = QOSInitWithPins
)

func (q LoadQOS) Upgrade(to LoadQOS) LoadQOS

type ManagedChannel 

type ManagedChannel struct {
	ChannelID   string
	ChannelName string
	GuildID     string

	// Messages posted to the channel get deleted after
	MessageLiveTime time.Duration
	MaxMessages     int
	KeepMessages    []string
	// if lower than CriticalMsgSequence, need to send one
	LastSentUpdate int
	IsDonor        bool
	// contains filtered or unexported fields
}

A ManagedChannel holds all the AutoDelete-related state for a Discord channel.

func (*ManagedChannel) AddMessage 

func (c *ManagedChannel) AddMessage(m *discordgo.Message)

func (*ManagedChannel) Disable 

func (c *ManagedChannel) Disable()

Remove this channel from all relevant datastructures.

Must be called with no locks held. Takes Bot, self, and reapq locks. Can be called on a fake ManagedChannel instance (e.g. (&ManagedChannel{ChannelID: ...}).Disable()), so the only member assumed valid is bot and ChannelID.

func (*ManagedChannel) String 

func (c *ManagedChannel) String() string

func (*ManagedChannel) UpdatePins
