CHANGELOG.md

@@ -7,10 +7,16 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 ### Removed
 - **Breaking**: Removed 1.0+ deprecated configurations `Pleroma.Upload, :strip_exif` and `:instance, :dedupe_media`
 - **Breaking**: OStatus protocol support
+- **Breaking**: MDII uploader
+- **Breaking**: Using third party engines for user recommendation
 
 ### Changed
+- **Breaking:** Pleroma won't start if it detects unapplied migrations
+- **Breaking:** attachments are removed along with statuses. Does not affect duplicate files and attachments without status.
 - **Breaking:** Elixir >=1.8 is now required (was >= 1.7)
 - **Breaking:** attachment links (`config :pleroma, :instance, no_attachment_links` and `config :pleroma, Pleroma.Upload, link_name`) disabled by default
+- **Breaking:** OAuth: defaulted `[:auth, :enforce_oauth_admin_scope_usage]` setting to `true` which demands `admin` OAuth scope to perform admin actions (in addition to `is_admin` flag on User); make sure to use bundled or newer versions of AdminFE & PleromaFE to access admin / moderator features.
+- **Breaking:** Dynamic configuration has been rearchitected. The `:pleroma, :instance, dynamic_configuration` setting has been replaced with `config :pleroma, configurable_from_database`. Please backup your configuration to a file and run the migration task to ensure consistency with the new schema.
 - Replaced [pleroma_job_queue](https://git.pleroma.social/pleroma/pleroma_job_queue) and `Pleroma.Web.Federator.RetryQueue` with [Oban](https://github.com/sorentwo/oban) (see [`docs/config.md`](docs/config.md) on migrating customized worker / retry settings)
 - Introduced [quantum](https://github.com/quantum-elixir/quantum-core) job scheduler
 - Enabled `:instance, extended_nickname_format` in the default config

 - Store status data inside Flag activity
 - Deprecated (reorganized as `UserRelationship` entity) User fields with user AP IDs (`blocks`, `mutes`, `muted_reblogs`, `muted_notifications`, `subscribers`).
 - Rate limiter is now disabled for localhost/socket (unless remoteip plug is enabled)
+- Logger: default log level changed from `warn` to `info`.
+- Config mix task `migrate_to_db` truncates `config` table before migrating the config file.

 - Admin API: Render whole status in grouped reports
 - Mastodon API: User timelines will now respect blocks, unless you are getting the user timeline of somebody you blocked (which would be empty otherwise).
+- Mastodon API: Favoriting / Repeating a post multiple times will now return the identical response every time. Before, executing that action twice would return an error ("already favorited") on the second try.

 - Mix task to list all users (`mix pleroma.user list`)
+- Mix task to send a test email (`mix pleroma.email test`)
 - Support for `X-Forwarded-For` and similar HTTP headers which used by reverse proxies to pass a real user IP address to the backend. Must not be enabled unless your instance is behind at least one reverse proxy (such as Nginx, Apache HTTPD or Varnish Cache).
 - MRF: New module which handles incoming posts based on their age. By default, all incoming posts that are older than 2 days will be unlisted and not shown to their followers.
 - User notification settings: Add `privacy_option` option.
+- Support for custom Elixir modules (such as MRF policies)
 - User settings: Add _This account is a_ option.

-Updating config settings only works with `:pleroma => :instance => :dynamic_configuration` setting to `true`.
+**Only works when configuration from database is enabled.**
-Module name can be passed as string, which starts with `Pleroma`, e.g. `"Pleroma.Upload"`.
-Atom keys and values can be passed with `:` in the beginning, e.g. `":upload"`.
-Tuples can be passed as `{"tuple": ["first_val", Pleroma.Module, []]}`.
-`{"tuple": ["some_string", "Pleroma.Some.Module", []]}` will be converted to `{"some_string", Pleroma.Some.Module, []}`.
-Keywords can be passed as lists with 2 child tuples, e.g.
-`[{"tuple": ["first_val", Pleroma.Module]}, {"tuple": ["second_val", true]}]`.
 
-If value contains list of settings `[subkey: val1, subkey2: val2, subkey3: val3]`, it's possible to remove only subkeys instead of all settings passing `subkeys` parameter. E.g.:
+Some modifications are necessary to save the config settings correctly:
-{"group": "pleroma", "key": "some_key", "delete": "true", "subkeys": [":subkey", ":subkey3"]}.
 
-Compile time settings (need instance reboot):
+- strings which start with `Pleroma.`, `Phoenix.`, `Tesla.` or strings like `Oban`, `Ueberauth` will be converted to modules;
-- all settings by this keys:
+```
+"Pleroma.Upload" -> Pleroma.Upload
+"Oban" -> Oban
+```
+- strings starting with `:` will be converted to atoms;
+```
+":pleroma" -> :pleroma
+```
+- objects with `tuple` key and array value will be converted to tuples;
+```

+- arrays with *tuple objects* will be converted to keywords;
+```
+[{"tuple": [":key1", "value"]}, {"tuple": [":key2", "value"]}] -> [key1: "value", key2: "value"]
+```
+
+Most of the settings will be applied in `runtime`, this means that you don't need to restart the instance. But some settings are applied in `compile time` and require a reboot of the instance, such as:
+- all settings inside these keys:
   - `:hackney_pools`
   - `:chat`
-  - `Pleroma.Web.Endpoint`
+- partially settings inside these keys:
-  - `Pleroma.Repo`

+# Configuring instance
+You can configure your instance from admin interface. You need account with admin rights and little change in config file, which will allow settings configuration from database.
+
+```elixir
+config :pleroma, configurable_from_database: true
+```
+
+## How it works
+Settings are stored in database and are applied in `runtime` after each change. Most of the settings take effect immediately, except some, which need instance reboot. These settings are needed in `compile time`, that's why settings are duplicated to the file.
+
+File with duplicated settings is located in `config/{env}.exported_from_db.exs` if pleroma is runned from source. For prod env it will be `config/prod.exported_from_db.exs`.
+
+For releases: `/etc/pleroma/prod.exported_from_db.secret.exs` or `PLEROMA_CONFIG_PATH/prod.exported_from_db.exs`.
+
+## How to set it up
+You need to migrate your existing settings to the database. This task will migrate only added by user settings.
+For example you add settings to `prod.secret.exs` file, only these settings will be migrated to database. For release it will be `/etc/pleroma/config.exs` or `PLEROMA_CONFIG_PATH`.
+You can do this with mix task (all config files will remain untouched):
+
+```sh tab="OTP"
+ ./bin/pleroma_ctl config migrate_to_db
+```
+
+```sh tab="From Source"
+mix pleroma.config migrate_to_db
+```
+
+Now you can change settings in admin interface. After each save, settings from database are duplicated to the `config/{env}.exported_from_db.exs` file.
+
+<span style="color:red">**ATTENTION**</span>
+
+**<span style="color:red">Be careful while changing the settings. Every inaccurate configuration change can break the federation or the instance load.</span>**

+- partially settings inside these keys:
+  - `:seconds_valid` in `Pleroma.Captcha`
+  - `:proxy_remote` in `Pleroma.Upload`
+  - `:upload_limit` in `:instance`
+
+## How to dump settings from database to file

+*Adding `-d` flag will delete migrated settings from database table.*
+
+```sh tab="OTP"
+ ./bin/pleroma_ctl config migrate_from_db [-d]
+```
+
+```sh tab="From Source"
+mix pleroma.config migrate_from_db [-d]
+```
+
+
+## How to completely remove it
+
+1. Truncate or delete all values from `config` table
+```sql
+TRUNCATE TABLE config;
+```
+2. Delete `config/{env}.exported_from_db.exs`.
+
+For `prod` env:
+```bash
+cd /opt/pleroma
+cp config/prod.exported_from_db.exs config/exported_from_db.back
+rm -rf config/prod.exported_from_db.exs
+```
+*If you don't want to backup settings, you can skip step with `cp` command.*
+
+3. Set configurable_from_database to `false`.
+```elixir

-
-* Enable and start postgresql server:
-
-```shell
-sudo systemctl enable --now postgresql-11.service
-```
-
-### Install PleromaBE
-
-* Add a new system user for the Pleroma service:
-
-```shell
-sudo useradd -r -s /bin/false -m -d /var/lib/pleroma -U pleroma
-```
-
-**Note**: To execute a single command as the Pleroma system user, use `sudo -Hu pleroma command`. You can also switch to a shell by using `sudo -Hu pleroma $SHELL`. If you don’t have and want `sudo` on your system, you can use `su` as root user (UID 0) for a single command by using `su -l pleroma -s $SHELL -c 'command'` and `su -l pleroma -s $SHELL` for starting a shell.
-
-* Git clone the PleromaBE repository and make the Pleroma user the owner of the directory:
-
-```shell
-sudo mkdir -p /opt/pleroma
-sudo chown -R pleroma:pleroma /opt/pleroma
-sudo -Hu pleroma git clone -b stable https://git.pleroma.social/pleroma/pleroma /opt/pleroma
-```
-
-* Change to the new directory:
-
-```shell
-cd /opt/pleroma
-```
-
-* Install the dependencies for Pleroma and answer with `yes` if it asks you to install `Hex`:
-
-```shell
-sudo -Hu pleroma mix deps.get
-```
-
-* Generate the configuration: `sudo -Hu pleroma mix pleroma.instance gen`
-  * Answer with `yes` if it asks you to install `rebar3`.
-  * This may take some time, because parts of pleroma get compiled first.
-  * After that it will ask you a few questions about your instance and generates a configuration file in `config/generated_config.exs`.
-
-* Check the configuration and if all looks right, rename it, so Pleroma will load it (`prod.secret.exs` for productive instance, `dev.secret.exs` for development instances):
-
-```shell
-mv config/{generated_config.exs,prod.secret.exs}
-```
-
-* The previous command creates also the file `config/setup_db.psql`, with which you can create the database:
-
-```shell
-sudo -Hu postgres psql -f config/setup_db.psql
-```
-
-* Now run the database migration:
-
-```shell
-sudo -Hu pleroma MIX_ENV=prod mix ecto.migrate
-```
-
-* Now you can start Pleroma already
-
-```shell
-sudo -Hu pleroma MIX_ENV=prod mix phx.server
-```
-
-### Finalize installation
-
-If you want to open your newly installed instance to the world, you should run nginx or some other webserver/proxy in front of Pleroma and you should consider to create a systemd service file for Pleroma.
-
-#### Nginx
-
-* Install nginx, if not already done:
-
-```shell
-sudo yum install nginx
-```
-
-* Setup your SSL cert, using your method of choice or certbot. If using certbot, first install it:
-
-```shell
-sudo yum install certbot-nginx
-```
-
-and then set it up:
-
-```shell
-sudo mkdir -p /var/lib/letsencrypt/
-sudo certbot certonly --email <your@emailaddress> -d <yourdomain> --standalone
-```
-
-If that doesn’t work, make sure, that nginx is not already running. If it still doesn’t work, try setting up nginx first (change ssl “on” to “off” and try again).
-
----
-
-* Copy the example nginx configuration to the nginx folder
-
-```shell
-sudo cp /opt/pleroma/installation/pleroma.nginx /etc/nginx/conf.d/pleroma.conf
-```
-
-* Before starting nginx edit the configuration and change it to your needs (e.g. change servername, change cert paths)
-* Enable and start nginx:
-
-```shell
-sudo systemctl enable --now nginx
-```
-
-If you need to renew the certificate in the future, uncomment the relevant location block in the nginx config and run:
-
-```shell
-sudo certbot certonly --email <your@emailaddress> -d <yourdomain> --webroot -w /var/lib/letsencrypt/
-```
-
-#### Other webserver/proxies
-
-You can find example configurations for them in `/opt/pleroma/installation/`.
-
-#### Systemd service
-
-* Copy example service file
-
-```shell
-sudo cp /opt/pleroma/installation/pleroma.service /etc/systemd/system/pleroma.service
-```
-
-* Edit the service file and make sure that all paths fit your installation
-* Enable and start `pleroma.service`:
-
-```shell
-sudo systemctl enable --now pleroma.service
-```
-
-#### Create your first user
-
-If your instance is up and running, you can create your first user with administrative rights with the following task:
-
-```shell
-sudo -Hu pleroma MIX_ENV=prod mix pleroma.user new <username> <your@emailaddress> --admin
-```

 # Switching a from-source install to OTP releases
+
 ## What are OTP releases?
 OTP releases are as close as you can get to binary releases with Erlang/Elixir. The release is self-contained, and provides everything needed to boot it, it is easily administered via the provided shell script to open up a remote console, start/stop/restart the release, start in the background, send remote commands, and more.
-### Can I still run the develop branch if I decide to use them?
-Yes, we produce builds for every commit in `develop`. However `develop` is considered unstable, please don't use it in production because of faster access to new features, unless you need them as an app developer.
-## Why would one want to switch?
-Benefits of OTP releases over from-source installs include:
-* **Less space used.** OTP releases come without source code, build tools, have docs and debug symbols stripped from the compiled bytecode and do not cointain tests, docs, revision history.
-* **Minimal system dependencies.** Excluding the database and reverse proxy, only `curl`, `unzip` and `ncurses` are needed to download and run the release. Because Erlang runtime and Elixir are shipped with Pleroma, one can use the latest BEAM optimizations and Pleroma features, without having to worry about outdated system repos or a missing `erlang-*` package.
-* **Potentially less bugs and better performance.** This extends on the previous point, because we have control over exactly what gets shipped, we can tweak the VM arguments and forget about weird bugs due to Erlang/Elixir version mismatches.
-* **Faster and less bug-prone mix tasks.** On a from-source install one has to wait untill a new Pleroma node is started for each mix task and they execute outside of the instance context (for example if a user was deleted via a mix task, the instance will have no knowledge of that and continue to display status count and follows before the cache expires). Mix tasks in OTP releases are executed by calling into a running instance via RPC, which solves both of these problems.
 
-### Sounds great, how do I switch?
-Currently we support Linux machines with GNU (e.g. Debian, Ubuntu) or musl (e.g. Alpine) libc and `x86_64`, `aarch64` or `armv7l` CPUs. If you are unsure, check the [Detecting flavour](otp_en.md#detecting-flavour) section in OTP install guide. If your platform is supported, proceed with the guide, if not check the [My platform is not supported](#my-platform-is-not-supported) section.
-### I don't think it is worth the effort, can I stay on a from-source install?
-Yes, currently there are no plans to deprecate them.
-
-### My platform is not supported
-If you think your platform is a popular choice for running Pleroma instances, or has the potential to become one, you can [file an issue on our Gitlab](https://git.pleroma.social/pleroma/pleroma/issues/new). If not, guides on how to build and update releases by yourself will be available soon.
 ## Pre-requisites
 You will be running commands as root. If you aren't root already, please elevate your priviledges by executing `sudo su`/`su`.
 
 The system needs to have `curl` and `unzip` installed for downloading and unpacking release builds.

 ## Moving content out of the application directory
 When using OTP releases the application directory changes with every version so it would be a bother to keep content there (and also dangerous unless `--no-rm` option is used when updating). Fortunately almost all paths in Pleroma are configurable, so it is possible to move them out of there.
 
 Pleroma should be stopped before proceeding.

 Pleroma is a federated social networking platform, compatible with GNU social, Mastodon and other OStatus and ActivityPub implementations. It is free software licensed under the AGPLv3.
 It actually consists of two components: a backend, named simply Pleroma, and a user-facing frontend, named Pleroma-FE. It also includes the Mastodon frontend, if that's your thing.
 It's part of what we call the fediverse, a federated network of instances which speak common protocols and can communicate with each other.
-One account on a instance is enough to talk to the entire fediverse!
+One account on an instance is enough to talk to the entire fediverse!
 
 ## How can I use it?
 
-Pleroma instances are already widely deployed, a list can be found here:
+Pleroma instances are already widely deployed, a list can be found at <http://distsn.org/pleroma-instances.html>. Information on all existing fediverse instances can be found at <https://fediverse.network/>.
-http://distsn.org/pleroma-instances.html
 
 If you don't feel like joining an existing instance, but instead prefer to deploy your own instance, that's easy too!
-Installation instructions can be found here:
+Installation instructions can be found in the installation section of these docs.
-[main Pleroma wiki](/)
 
 ## I got an account, now what?
-Great! Now you can explore the fediverse!
+Great! Now you can explore the fediverse! Open the login page for your Pleroma instance (e.g. <https://pleroma.soykaf.com>) and login with your username and password. (If you don't have an account yet, click on Register)
-- Open the login page for your Pleroma instance (for ex. https://pleroma.soykaf.com) and login with your username and password.
-(If you don't have one yet, click on Register) :slightly_smiling_face:
 
 At this point you will have two columns in front of you.
 
 ### Left column
-- first block: here you can see your avatar, your nickname a bio, and statistics (Statuses, Following, Followers).
+
-Under that you have a text form which allows you to post new statuses. The icon on the left is for uploading media files and attach them to your post. The number under the text form is a character counter, every instance can have a different character limit (the default is 5000).
+- first block: here you can see your avatar, your nickname and statistics (Statuses, Following, Followers). Clicking your profile pic will open your profile.
-If you want to mention someone, type @ + name of the person. A drop-down menu will help you in finding the right person. :slight_smile:
+Under that you have a text form which allows you to post new statuses. The number on the bottom of the text form is a character counter, every instance can have a different character limit (the default is 5000).
+If you want to mention someone, type @ + name of the person. A drop-down menu will help you in finding the right person.
+Under the text form there are also several visibility options and there is the option to use rich text.
+Under that the icon on the left is for uploading media files and attach them to your post. There is also an emoji-picker and an option to post a poll.
 To post your status, simply press Submit.
+On the top right you will also see a wrench icon. This opens your personal settings.
 
 - second block: Here you can switch between the different timelines:
    - Timeline: all the people that you follow
-  - Mentions: all the statutes where you are mentioned
+   - Interactions: here you can switch between different timelines where there was interaction with your account. There is Mentions, Repeats and Favorites, and New follows
+   - Direct Messages: these are the Direct Messages sent to you
    - Public Timeline: all the statutes from the local instance
-  - The Whole Known Network: everything, local and remote!
+   - The Whole Known Network: all public posts the instance knows about, both local and remote!
-
+   - About: This isn't a Timeline but shows relevant info about the instance. You can find a list of the moderators and admins, Terms of Service, MRF policies and enabled features.
-- third block: this is the Chat block, where you communicate with people on the same instance in realtime. It is local-only, for now, but we're planning to make it extendable to the entire fediverse! :sweat_smile:
+- Optional third block: This is the Instance panel that can be activated, but is deactivated by default. It's fully customisable and by default has links to the pleroma-fe and Mastodon-fe.
-
 - fourth block: This is the Notifications block, here you will get notified whenever somebody mentions you, follows you, repeats or favorites one of your statuses.
 
 ### Right column
-This is where the interesting stuff happens! :slight_smile:
+This is where the interesting stuff happens!
 Depending on the timeline you will see different statuses, but each status has a standard structure:
-- Icon + name + link to profile. An optional left-arrow if it's a reply to another status (hovering will reveal the replied-to status).
-- A + button on the right allows you to Expand/Collapse an entire discussion thread. It also updates in realtime!
-- A binocular icon allows you to open the status on the instance where it's originating from.
-- The text of the status, including mentions. If you click on a mention, it will automatically open the profile page of that person.
-- Four buttons (left to right): Reply, Repeat, Favorite, Delete.
 
-## Mastodon interface
+- Profile pic, name and link to profile. An optional left-arrow if it's a reply to another status (hovering will reveal the replied-to status). Clicking on the profile pic will uncollapse the user's profile.
-If the Pleroma interface isn't your thing, or you're just trying something new but you want to keep using the familiar Mastodon interface, we got that too! :smile:
+- A `+` button on the right allows you to Expand/Collapse an entire discussion thread. It also updates in realtime!
-Just add a "/web" after your instance url (for ex. https://pleroma.soycaf.com/web) and you'll end on the Mastodon web interface, but with a Pleroma backend! MAGIC! :fireworks:
+- An arrow icon allows you to open the status on the instance where it's originating from.
-For more information on the Mastodon interface, please look here:
+- The text of the status, including mentions and attachements. If you click on a mention, it will automatically open the profile page of that person.
-https://github.com/tootsuite/documentation/blob/master/Using-Mastodon/User-guide.md
+- Three buttons (left to right): Reply, Repeat, Favorite. There is also a forth button, this is a dropdown menu for simple moderation like muting the conversation or, if you have moderation rights, delete the status from the server.
+
+### Top right
+
+- The magnifier icon opens the search screen where you can search for statuses, people and hashtags. It's also possible to import statusses from remote servers by pasting the url to the post in the search field.
+- The gear icon gives you general settings
+- If you have admin rights, you'll see an icon that opens the admin interface
+- The last icon is to log out
+
+### Bottom right
+On the bottom right you have a chatbox. Here you can communicate with people on the same instance in realtime. It is local-only, for now, but there are plans to make it extendable to the entire fediverse!
+
+### Mastodon interface
+If the Pleroma interface isn't your thing, or you're just trying something new but you want to keep using the familiar Mastodon interface, we got that too!
+Just add a "/web" after your instance url (e.g. <https://pleroma.soycaf.com/web>) and you'll end on the Mastodon web interface, but with a Pleroma backend! MAGIC!
+The Mastodon interface is from the Glitch-soc fork. For more information on the Mastodon interface you can check the [Mastodon](https://docs.joinmastodon.org/) and [Glitch-soc](https://glitch-soc.github.io/docs/) documentation.
 
 Remember, what you see is only the frontend part of Mastodon, the backend is still Pleroma.
