 Changelog
 =========
 
-Version 2.0.0
--------------
-
-### Major Features
-
-- Replaced Hotpatch with save patching.  Removed the Hotpatch scenario and
-  the depency on it for getting code into the game.  Added a save patcher than
-  runs before starting up Factorio that patches in lua modules based on the
-  event_loader lib into the savegame.  Regular freeplay games can now be
-  used with Clusterio and will be compatible without having to convert them
-  to Hotpatch.
-- Daemonized slaves.  Slaves now have the ability to run multiple Factorio
-  instances, starting and stopping them individually.  To manage this the
-  local command line interface has been replaced with a remote interface on
-  the master server that can be accessed through the clusterctl cli tool.
-- Rewritten the communication between slaves and the master from scratch.  The
-  new system is based on a WebSocket connection between the slaves and the
-  master server and provides efficient validated bi-directonal communication.
-- Rewritten the plugin system from scratch.  Plugins now inherit from
-  a base class and use the same WebSocket connection Clusterio uses to
-  communicate.
-- New configuration system with support for initializing configs when needed,
-  modifying config entries using built-in commands, and updating instance
-  configuration remotely.
-
-### Features
-
-- Added export of pollution statitics.
-- Reconnection logic that esures no data is dropped talking to the master
-  server provided the session can be resumed.
-- Added support for having multiple Factorio installs and selecting which
-  version to use on a per instance basis.
-- Added config to specify which path the master interface is accessed under,
-  allowing it to be proxied behind web-server.
-- Added WebSocket usage statistics.
-- Added commands sent statistic.
-
-### Changes
-
-- Fixed sslCert and sslPrivKey entries being ignored in the config.
-- Changed ssl key creation to be done at startup instead of on npm install.
-- Added error handling during master startup.
-- Factorio game and rcon port now defaults to a random port above 49151.
-- Removed unimplemented mods update command.
-- Fixed rcon password being generated with Math.random().
-- Added plugins directory to the views path.  This makes it possible for
-  plugins to render their own ejs views or pages in their own folders by
-  using paths of the format "pluginName/path/to/page-or-view".
-- Replaced the per instance copy of the shared Factorio mods with
-  symlinks.  On Windows hard links are used instead due to the
-  privileges requirements of symlinks.
-- Changed the per instance scenario folder to be linked instead of
-  copied on instance creation.
-- Instance id is no longer derived from the rcon password, instead it's
-  generated upon instance creation and stored in the instance config.
-- The game port, RCON port and RCON password instance config entries are are
-  now null by default, indicating that a random one will be generated every
-  time the instance is started.
-- Removed the broken client download command as this would download
-  pre-releases.
-- Moved the item database and HTTP definitions for /api/place, /api/remove,
-  /api/inventory, /api/inventoryAsObject and the web interface view for the
-  storage page into the clusterioMod plugin.  If you disable this plugin
-  then these things will not be available.
-- Removed undocumented --port and --rcon-port arguments to client.
-- Removed undocumented FACTORIOPORT and RCONPORT enviroment variable
-  handling in client.
-- Removed redundant call to /api/slaves in globalChat plugin.
-- Removed broken serverManager plugin.
-- Removed factorio_version from config.  The version installed is auto
-  detected and used instead.
-- Removed the playerManager specific command CLI tools/delete_player.js.
-- Creating an instance, assigning it to a slave, creating a save for an
-  instance and starting an instance is now four separate commands.
-- Removed oddball limits to slaves.json size.
-- Moved slave specific and instance specific configuration into their own
-  configuration files.
-- Removed unused binary option from plugin config.
-- Removed info and shout command from globalChat plugin
-- Removed mirrorAllChat and enableCrossServerShout configuration options for
-  globalChat plugin.
-- Removed UPSdisplay plugin.  UPS statistics is exported by the statistics
-  exporter plugin.
-- Master server now defaults to hosting on https on port 8443.
-- Renamed client to slave.
-
-### Breaking Changes
-
-- lib/authenticate no longer requires config to be passed to it.  Breaks
-  playerManager.
-- The masterIP and masterPort config entries has been merged into masterURL.
-  Breaks discordChat, playerManager, serverSelect, trainTeleports and
-  clusterioModel.
-- Instance names can no longer be invalid Windows file names.
-- Removed config management from the command line and the server manager.
-- Moved ejs templates into views folder and changed their extension to
-  .ejs.  Breaks playerManager.
-- Mods are no longer copied from the per instance instanceMods directory.
-  If you need per instance mods you can now place them directly in the mods
-  directory inside the instance folder.
-- Hotpatch scenarios and code loading is no longer compatible with Clusterio.
-  Breaks playerManager, serverSelect, and tranTeleports.
-- Removed getLua and getCommand from lib/clusterTools.  If you need to run
-  more than the most trivial of code in commands use the save patcher and
-  add in a remote interface.
-- Removed mod uploading and distributing from the HTTP interface.  Breaks
-  the old unmaintained and no longer needed factorioClusterioClient.
-- Removed the remoteCommands plugin and the old runCommand interface.  Breaks
-  playerManager and external tools sending commands.
-- Removed broken serverManager plugin.
-- Removed fields info, time, rconPort, rconPassword, serverPort, unique,
-  mods, instanceName, playerCount, mac, and meta from the slaves in the
-  slave database.
-- Removed getInstanceName and lib/clusterTools.  Breaks playerManager,
-  and discordChat.
-- Removed the /api/rconPasswords, and /api/slaves endpoints.  Breaks web
-  interface, trainTeleports, and discordChat.
-- Removed the /api/getSlaveMeta and /api/editSlaveMeta endpoints.  Breaks
-  researchSync, and UPSdisplay.
-- Removed the hello event from the socket connection handshake.  Breaks
-  playerManager, trainTeleports, serverSelect, and discordChat
-- Changed the format of database/slaves.json.
-- Removed the output file subscription system.  Breaks inventoryImports,
-  playerManager, trainTeleports, serverSelect and researchSync.
-- Removed the factorioOutput hook from instance plugins.  The onOutput
-  hook provides parsed output instead.
-- Removed the onLoadFinish hook from master plugins.
-- Moved plugins from the sharedPlugins directory to plugins directory.
-- Implemented a new plugin system that replaces the old.  Breaks all plugins.
-- Removed express metric http_request_duration_milliseconds metric.
-- Removed socket.io metrics socket_io_connected, socket_io_connect_total,
-  socket_io_disconnect_total, socket_io_events_received_total,
-  socket_io_events_sent_total, socket_io_recieve_bytes, and
-  socket_io_transmit_bytes,
-- Removed clusterio_connected_instaces_gauge and added
-  clusterio_master_connected_clients_count in its place.
-- Renamed clusterio_player_count_gauge to
-  clusterio_statistics_exporter_instance_player_count

-  always allowed with the move to master managing slaves/instances.
-- Removed `--databaseDirectory`, `--masterPort`, and `--sslPort` command line
-  arguments from the master server.

-
-
-Version 1.2.4
--------------
-
-- Removed broken remote combinator signaling.
-- Fixed research sync endlessly updating already researched technologies
-- Removed obsolete item/fluid statistics from clusterioMod
-- Removed per mod upload logging when config.uploadModsToMaster disabled
-- Fixed bcrypt failing to install on windows due to the new version not
-  having Windows binaries.
-
-
-Version 1.2.3
--------------
-
-- Disabled uploading mods to the master server by default as this is mostly
-  just a waste of bandwidth with the mod portal being integrated into the
-  game now.
-- Fixed researchSync breaking with heavily modded games due to the tech tree
-  exceeding the default 100kb limit on JSON payloads.
-- Fixed the command inventoryImport sends referencing player instead of
-  character, and trying to count the non-existant quick bar slots.
-- Fixed inventoryImport never receiving the script output after the default
-  mode for reading script output changed to tail mode.
-- Fixed desync caused by the mods and loaded mods arrays in Hotpatch getting
-  out of sync when plugins update their scenario mod code.  To fix existing
-  games you will need copy lib/scenarios/Hotpatch/hotpatch/mod-tools.lua
-  over the existing mod-tools.lua in the save's hotpatch folder.
-- Updated the Windows install instructions.
-
-
-Version 1.2.2
--------------
-
-- Fixed possible crash with modded technologies named the same as a built-in
-  Object prototype property in researchSync.
-- Fixed progress of a current infinite tech carrying over to the next one
-  when researching it and another node completes it in researchSync.
-- Fixed progress of a previous infinite tech from another node being applied
-  to the current one in researchSync.
-- Fixed crash in researchSync when modded technologies are present only on some
-  nodes.
-- Fixed install failing due to bcrypt version less than 3 not being supported
-  on node v10.
-- Reordered install instructions to avoid problem with npm creating files owned
-  by root in the home directory.
-- Swapped curl out with wget in the install instructions as the latter comes
-  pre-installed on Ubuntu.
-
-### Breaking Changes
-
-- Node.js versions below 10 are no longer supported.

-need an authentication token from the master server.  This token is
-written to secret-api-token.txt on the master server when it is started
-up.
-
-To set up the configuration for a new local slave run the following.
-
-    node slave config set slave.name "Local"
-    node slave config set slave.master_token "<token>"
-
-This will write a new `config-slave.json` file in the current directory
-(you can change the location with the `--config` option) with the name
-and token provided.  If you are connecting to a remote master server you
-will also need to set the `slave.master_url` option to that url.
-
-You can list the config of a slave with the `node slave config list`
-command.  Use `node slave config --help` for more information.
-
-Once the config is set up run the slave with
-
-    node slave run
-
-
-### Instances
-
-Instances are created, managed and started from the master server.  For
-now the only interface available is the `clusterctl` command line tool
-included in Clusterio.  You can run this tool from any slave, or the
-master server without having to set up a config, if you want to manage
-the cluster from somewhere else you will need to set the
-`control.master_url` and `control.master_token` options with the  `node
-clusterctl control-config set` command:
-
-The basic operations to start a new instance is the following
-
-    node clusterctl create-instance --name "My instance"
-    node clusterctl assign-instance --instance "My instance" --slave "Local"
-    node clusterctl create-save --instance "My instance"
-    node clusterctl start-instance --instance "My instance"
-
-The first line creates the instance configuration on the master server.
-The second assigns the instance to a slave which creates the instance
-directory and files needed to run the instance on the given slave.  The
-third line creates a new savegame for the instance.  You could also
-upload your own save to the instance directory instead.  And finally the
-fourth line starts the instance.
-
-There are many more commands available with clusterctl.  See
-`node clusterctl --help` for a full list of them.
+2. Drop it into ./factorio/mods
 
+3. Run factorio and connect to slave as a normal MP game. You will find the port number to connect to at http://[masterAddress]:8080

+**To create a new instance/start it**
+
+    node client.js start [instanceName]
+
+**Other instance management tools:**
+```
+node client.js delete [instanceName]
+node client.js list
+```
+**To update clusterio to the latest version:**
+
+1. Download the latest zip version of factorio for your platform manually from factorio.com. Place it in the project root folder and call it "factorio" (folder name is specified in config.json)
+
+2. Grab the latest version of the repo
+
+```
+git pull
+
+npm install --only=production
+```
+
+3. Download the latest version of the factorioClusterioMod from its github repo
+```
+node client.js manage shared mods add clusterio

-Communication Layer
-===================
-
-<sub>This document describes the communication layer in Clusterio and
-unless you're developing Clusterio it's probably not going to be very
-useful for you.</sub>
-
-Communication is facilitated by the lib/link library and is based on
-three core abstractions: links, connectors and messages.  Links
-represents one side of a two way communication pipe, connectors deal
-with connecting and establishing communication, and messages are the
-content sent over the link.
-
-
-Link
-----
-
-The Link class represents one side of a two way communication channel
-where the actual communication is done by a connector associated with
-the link.  The link also knows what the endpoint types it's connected to
-are via the source and target attributes.
-
-The endpoint types currently implemented are master, slave, instance,
-and control.  Although slave and instances run in the same Node.js
-program they use virtual links to communicate between them in order to
-simplify the communication architecture.
-
-Upon creation the link will register with the connector in order to
-receive and process messages from it.  The messages received are
-validated using the validator registered for the type of the message.  A
-message for which there is no validator for is considered an error.
-
-
-Connector
----------
-
-The connector used with a link is responsible for establishing and/or
-maintain the connection that messages are sent over.  Reconnect logic is
-expected to be implemented in the connector, though this has not yet
-been done.
-
-There's also the virtual connector which lets two links in the same
-program be connected to each other without having to establish a
-network connection.
-
-
-Message
--------
-
-There's two types of messages currently implemented apart from the
-Link builtin close message and that's Request and Event.  The builtin
-messages are defined in [lib/link/messages.js](../lib/link/messages.js)
-and are attached to links via the attachAllMessages function, which is
-usally called in the Link subclass constructor.
-
-The messages define which links they are valid on and only attaches
-handlers for those links.  There's also a forwarding mechanism for when
-a request or event is to be forwarded another hop.

-Configuration System
-====================
-
-<sub>This document describes the implementation and inner working of the
-configuration system in Clusterio, and unless you're developing
-Clusterio it's probably not going to be very useful for you.</sub>
-
-Clusterio uses a group based configuration system to manage settings for
-the master server, instances, slaves, and the clusterctl utility.
-Plugins get their own config group for the master server and instances
-which they can add their own fields to.  The fields are defined early in
-the startup, and the groups and their fields for disabled plugins will
-still be created.
-
-The built-in config groups and their fields are defined in
-[/lib/config/definitions.js](lib/config/definitions.js) while plugins
-can add their own config groups to the `MasterConfigGroup` and
-`InstanceConfigGroup` properties of the `info.js` export using
-subclasses of `PluginConfigGroup`.  The plugin group has the enabled
-field pre-defined on it, and it's used to enable/disable plugins.
-
-
-Defing Fields
--------------
-
-Fields are defined using the `define` class method on group classes
-after the groupName have been set and before the class has been
-finalized.  The `define` method takes an object as argument with the
-following properties:
-
-**type**:
-    The type of config value this field will support.  The supported
-    values are boolean, string, number, and object, and if an attept is
-    made to set the field to a value that is not of the right type it
-    will be reject unless it's a string that can be converted to the
-    right type.
-
-**name**:
-    Name of the configuration field, this is the primary way the field
-    is accessed, both in code and on the command line.  As such it
-    should follow the lower\_case\_underscore style and not contain any
-    spaces or dots.
-
-**title** (optional):
-    Text used to identify the config field in user interfaces.
-
-**description** (optional):
-    Text used to describe the config field in user interfaces.
-
-**enum** (optional):
-    Array of acceptable values this field can have.  Attempts to set a
-    value not in this array will be rejected, which makes it useful for
-    making enumareted list of choices.
-
-**optional** (optional):
-    True if this field can be set to null.  Defaults to false.
-
-**initial_value** (optional if optional is true):
-    Value this config field should take in a newly initialized config.
-    This can also be an async function returning the value to use.
-
-If the value for a field stored in on disk somehow ends up being invalid
-the field will take on the initial\_value instead when the config is
-loaded.
-
-
-Accessing Fields
-----------------
-
-On the Config instance there's two ways to access fields:  through the
-set and get methods using dot notation.  E.g.:
-
-    let value = configInstance.get("group.field");
-
-Or by getting the group first and then calling set or get on that.
-E.g.:
-
-    let value = configInstance.group("group").get("field")
-
-The set method takes an extra argument, which is the value to set the
-field to.  If the value is not valid this will throw an InvalidValue
-exception, if the group or field doesn't exist it will throw an
-InvalidField exception.
-
-
-Config Lifecycle
-----------------
-
-Values for all config fields are created when the config is initialized,
-as well as for any fields with missing values when a config is loaded.
-Once a field has a value it is never automatically removed, even if the
-field or group it was part of no longer exists.  This ensures that
-plugin configuration is not lost should the server be started up without
-the plugins that defined the configuration installed.
-
-For instance configs, they are kept on the master server and serialized
-and sent over to the relevant slaves on startup.  This makes it possible
-to edit instance configs when the slave the instance is on is offline.
-A copy is also stored in the instance directory on the slave, and this
-config will be deliverd to the master server on slave startup, which
-enables instances to be copied between clusters as long as their IDs are
-unique.

-You are probably reading this because you want to contribute code to
-Clusterio.  Great!  We need people like you.  Though we have some
-conventions and workflows that we kindly ask you to follow.

-
-
-Workflow
---------
-
-While we don't require you to follow this workflow, it makes things much
-simpler for both you and us if you choose to do so.  Especially when it
-comes to making the commit history reflect what happened and not be a
-giant ball of mess.  GitHub's git workflow is less than ideal for
-dealing with small feature-branches so you might see things being done
-here a little diffrent than the usual.
-
-It is recommended that you use the command line git version for doing
-the operations described here.  GUI wrappers tend to have different
-ideas of what is what and you might find it difficult to make it do the
-things described here.  For doing the actual commits though, your
-faviorit git GUI should work just fine.
-
-If you pressed the fork button on GitHub and used `git clone` _on your
-own fork_ you can skip to the next paragraph.  Otherwise you will have
-to click the fork button and clone your fork.  If you already cloned the
-main GitHub repository you can change your clone to point at your own
-fork using the `git remote` command, but it's probably easier to delete
-your local clone and clone it again.
-
-To keep your local repository up to to date with the main repository add
-the main repository as a remote.
-
-    git remote add upstream https://github.com/clusterio/factorioClusterio
-
-After this running `git fetch upstream` will get the updated branches
-from the main repository.  Do not run `git pull upstream` it will mess
-thing up!
-
-
-### Starting a Feature Branch
-
-Development is done exclusively in feature branches.  This means the
-first thing to do before starting any development at all is to make a
-new branch starting from the master or 1.2.x branch of the main
-repository.  To do this check out that branch from the main repository
-(substitute master for 1.2.x if you're working on that branch.)
-
-    git fetch upstream
-    git checkout upstream/master
-
-This will give a warning about detached HEAD which means you did it
-correctly.  Now you can make a feature branch based on this with.
-
-    git checkout -b my-feature-branch
-
-The name of the branch is not important, as long as it's not a name
-you've used before.  But it's nice to have its name be somewhat
-descriptive of what it implements.
-
-
-### Submitting a Pull Request
-
-Once you've commited changes to your feature branch that you want to
-have included into the main repository push it to you fork with
-
-    git push origin my-feature-branch
-
-and make a pull request through the GitHub web interface.  You can also
-pass the `--set-upstream` (or `-u`) flag to make `git push` do the same
-thing for this branch.  After your feature branch have been merged you
-should consider it final.  If there are more changes you want to have
-merged or mistakes you need to fix you must start a new feature branch
-and submit a new pull request
-
-
-### Editing your Feature Branch
-
-Until your feature branch is merged you can edit it as you see fit by
-using the rebase tool.  If your feature branch has been merged however
-it's final and you will have to start a new feature branch and submit
-that in a new pull request.  The base usage of rebase assuming you are
-checked out on your feature branch is the following command (substitute
-master with 1.2.x if your feature branch is based on that)
-
-    git rebase -i upstream/master
-
-This will open up an editor with the commits of your feature branch and
-let you reorder, edit, and remove commits as you see fit.
-
-If the main repository has been updated and you have fetched down those
-updates with `git fetch upstream` this will also move your feature
-branch so that it is based on the latest commit from the main
-repository.
-
-If you have already pushed your feature branch to your fork a simple
-`git push origin my-feature-branch` will no longer work as the histories
-are different, instead you will have to run
-
-    git push origin +my-feature-branch
-
-The + sign signifies a force push and should be used with care.  If you
-have a pull request that has not yet been merged submitted for this
-feature branch this will update the pull request too.
-
-
-### Resolving Merge Conflicts
-
-The best way to resolve merge conflicts in feature braches is to rebase
-it on top of the updated upstream.  Run the following commands
-(substitute master with 1.2.x if your feature branch is based on that)
-
-    git fetch upstream
-    git rebase upstream/master
-
-This will stop on the commit(s) that caused the merge conflict and let
-you resolve them manually before continuing.  Once you're done force
-push your updated feature branch with
-
-    git push origin +my-feature-branch
-
-
-### Updating Your GitHub Fork
-
-No.  This is pointless busywork that accomplishes nothing.  Fetch the
-main repository directly as described above and base your feature
-branches on the refs from it.  GitHub has no interface or functionality
-for keeping the branches in your fork up to date with the branches in
-the main repository and there is no point in doing this for our feature
-branch based workflow.
-
-
-Changelog
----------
-
-There's a [Changelog](../CHANGELOG.md) in the root of the project.  If
-you make changes that are visible to users of this project you should
-add an entry to the changelog describing what has changed.  The format
-of this log should be self explanatory, please follow it carefully.
-
-
-Supported Node.js and Factorio Versions
----------------------------------------
-
-Clusterio run on Node.js v12 and up, v11.13.0+ and v10.16.0+, make sure
-to check that the Node builtin API's and npm packages you use are
-supported on these versions.  The Travis CI tests are runned on whatever
-version of Node.js v10 is the default, which at the time of writing is
-v10.18.0.
-
-For Factorio Clusterio 2.0 aims to support version 0.17.69 and up,
-including the latest experimental release.  It's recommended that you
-use the lua API reference for 0.17.69, as there's no information on what
-version Factorio API's were introduced in.  The Travis CI tests are
-runned against latest experimental release.
-
-
-Code Style
-----------
-
-The style of the code is a bit of a mixed bag at the moment.  But there
-are at least a few things that have been agreed upon.
-
-
-### Strings
-
-JavaScript and Lua code should use double quoted strings (`"string"`)
-for all strings with the only exception that strings that contain double
-quotes may use single quotes (i.e., `'String with "quotes"'`.)  For
-JavaScript template literals may also be used where appropriate.
-
-There are places in the codebase that are using `'single'` quoted
-strings.  Should you be modifying such code use double quotes on new and
-modified lines and leave the rest untouched.
-
-
-### Indenting
-
-JavaScript code should be indented with tabs.  There are places in the
-codebase that are mixing tabs and spaces or uses only spaces for
-indents.  Should you be modifiying such code that is mixing spaces and
-tabs as indending you should update the indenting to use tabs _on the
-code you change_ while leaving the rest of the code untouched.
-
-Lua code should be indented with 4 spaces.
-
-
-### Line Length
-
-Lines are limited to 120 characters where tabs count as 4 characters.
-If the argument list for a function or expressino for compound statement
-gets very long break them out on their own line(s).  For example:
-
-    function foo(
-        really, long, argument, list,
-        over, multiple, lines
-    ) {
-        if (
-            really && long && expression
-            || over && multiple && lines
-        ) {
-            // code
-        }
-    })

-Factorio Mods
--------------
-
-Factorio mods that do not interact with Clusterio should not have any
-conciderations that need to be taken into account for them to work with
-Clusterio.
-
-
-Factorio Scenarios
-------------------
-
-Clusterio patches saves and because of this scenarios have a few
-limitations and must explicitly mark themselves as compatible with
-Clusterio to work.  The main limitation is that the
-[event_handler](https://github.com/wube/factorio-data/blob/master/core/lualib/event_handler.lua)
-lib must be used, and control.lua cannot contain any code other than
-calls to event_handler loading the relevant libs of the scenario.
-This is because the control.lua file will be overwritten by the save
-patcher.  Scenarios also cannot use the event registring functions
-exposed by `script` such as `script.on_event` or `script.on_nth_tick` as
-using these will overwrite the handlers registered by the
-event_handler lib.
-
-A breif description of the usage of the event_handler library is
-provided in the [event_handler interface](#event_handler-interface)
-section.
-
-Once a scenario is made using the event_handler it should have a
-control.lua file that looks something like this:
-
-```lua
--- control.lua
-local event_handler = require("event_handler")
-event_handler.add_lib(require("module_foo"))
-event_handler.add_lib(require("module_bar"))
-```
-
-To make Clusterio recognize and correctly handle this scenario it
-needs to include a clusterio.json file with following content:
-
-```json
-{
-    "scenario": {
-        "name": "example-scenario",
-        "modules": [
-            "module_foo",
-            "module_bar"
-        ]
-    }
-}
-```
-
-This tells Clusterio that it should load both module_foo and module_bar
-by passing the result of requiring them to the  `add_lib` function when
-writing a new control.lua file to the save.
-
-
-### event_handler interface
-
-<sub>**Note:** At the time of writing the event_handler lib has been
-a part of Factorio since at least 0.17.4, and was moved from base to
-core in 0.17.63 but is still not documented anywhere.  A brief
-description is provided here for this reason.</sub>
-
-The event_handler lib provides a simple interface for registring
-multiple callbacks to the same events without having to be concerned
-with callback chaining or overwriting callbacks defined elsewhere.  It
-works by taking over the task of registring the actual callbacks with
-Factorio, providing its own interface for the rest of the code to use.
-
-The sole function of interest exported by event_handler is `add_lib`
-which accepts a table with event handler callbacks definitions that it
-will register.  The following entries are recognized by `add_lib`, all
-of which are optional:
-
-- `on_init`:
-    Callback called when the callback of `script.on_init` is invoked.
-- `on_load`:
-    Callback called when the callback of `script.on_load` is invoked.
-- `on_configuration_changed`:
-    Callback called when the callback of
-    `script.on_configuration_changed` is invoked.
-- `events`:
-    Table mapping event ids as defined in `defines.events` to callbacks.
-    For example the table `{ [defines.events.on_player_died] = foo }`
-    will call bar with the usual `event` table as argument every time a
-    player dies.
-- `on_nth_tick`:
-    Table mapping the nth tick number to a callback.  For example the
-    table `{ [30] = bar }` will call bar every 30th tick.
-- `add_remote_interface`:
-    Callback called before on_init/on_load callbacks<sup>[1]</sup>.  It
-    has no special meaning and receives no arguments but should be used
-    for registring remote interfaces.
-- `add_commands`:
-    Callback called before on_init/on_load callbacks<sup>[1]</sup>.  It
-    has no special meaning and receives no arguments but should be used
-    for registring commands.
-
-<sub>1: Before 0.17.69 these callbacks were called after
-on_init/on_load.</sub>
-
-The usual way to use `add_lib` is to define the table of events to
-register in a separate file and return it, then load it in control.lua
-via `require` before passing it to `add_lib`.  For example a module
-could be defined as
-
-```lua
--- example.lua
-local function my_handler(event)
-    local name = game.player[event.player_index].name
-    game.print("It appears that " .. name .. " has died")
-end
-
-return {
-    on_init = function() game.print("example_lib init") end,
-    events = {
-        [defines.events.on_player_died] = my_handler,
-    },
-}
-```
-
-And then in control.lua the following used to load it with `add_lib`:
-
-```lua
--- control.lua
-local event_handler = require("event_handler")
-event_handler.add_lib(require("example"))
-```
-
-Because the event_handler lib registers events itself you may not use
-`script.on_load` or `script.on_init` at all in your code and any usage
-of `script.on_configuration_changed`, `script.on_nth_tick` and/or
-`script.on_event` will cause the corresponding events registered with
-event_handler to break and should therefore not be used.
-
-There's also the `add_libraries` function exported by event_handler,
-which accepts a table and calls `add_lib` for each value in the table.
-
-
-Communicating with Clusterio
-----------------------------
-
-There's a poorly to virtuarly undocumented HTTP interface that can be
-used to communicate with Clusterio to do things like get the status of
-instances, grab items from the store, run commands on instances, etc,
-etc.  For now you can read the source code, and maybe ask on the Discord
-for some pointers if you get stuck.
-
-
-Clusterio Modules
------------------
-
-Modules are primarily used by plugins to inject code into Factorio games
-with the save patcher, though it's also possible to make stand alone
-modules that are loaded into the game if you don't need the capabilites
-of the plugin system.  The save patcher puts modules into the `modules`
-folder of the Factorio save and adds code to `control.lua` to load the
-module according to the `load` and `require` options to the module.json
-file.
-
-Stand alone modules are placed into the modules folder of Clusterio,
-plugin modules are located in the module folder of the plugin.  In
-either case a `module.json` file is required and has the following
-structure:
-
-```json
-{
-    "name": "my_module",
-    "version": "1.2.0",
-    "dependencies": {
-        "clusterio": "*",
-        "foo": ">=0.4.2"
-    },
-    "require": ["bar.lua"],
-    "load": ["foo.lua"]
-}
-```
-
-The following entries are supported in the module.json file:
-
-- `name`:
-    Name of the module, must match the folder the module is located in
-    for stand alone modules or the name of the plugin the module is
-    located in.
-- `version`:
-    Version of the module.  Must be compatible with [Semantic Versioning
-    2.0.0](https://semver.org/).  In plugin modules this defaults to the
-    version of the plugin otherwise it's required.
-- `dependencies`:
-    Optional mapping of modules this module depends on and their
-    version.  In the example `>=0.4.2` means that the foo module must be
-    at least version 0.4.2.  See the [Ranges
-    syntax](https://www.npmjs.com/package/semver#ranges) of the
-    node-semver package for a full description of what operators are
-    supported.  The events for dependencies is invoked before the events
-    of the dependent, and starting an instance will fail if the
-    dependencies cannot be satisfied.  If not specified it will default
-    to depending on `clusterio`.  Make sure to add `clusterio` to your
-    dependencies if you add other dependencies and depend on the Lua API.
-- `require`:
-    Lua files to require in `control.lua`.  This should only really be
-    needed if you want to make a global function available for use in
-    Lua commands.  The paths are relative to the module's own folder and
-    should be specified using forward slashes as directory sepparators
-    if it's located in a sub directory in the module.
-- `load`:
-    Lua files to load with the `event_handler` lib, the result of
-    requiring the file will be passed to the `add_lib` function of the
-    `event_handler` lib in `control.lua`.  See the section on the
-    [event_handler interface](#event_handler-interface) for a detailed
-    description on how the `event_handler` lib works.  The paths are
-    relative to the module's own folder and should be specified using
-    forward slashes as directory sepparators if it's located in a sub
-    directory in the module.
-
-It's recommended to use the new style of defining modules in Lua, as
-well as avoid the use of global variables as much as possible.  This
-means always declearing your top level variables and functions local and
-exporting only the things you need in other files.  You can require
-other files in your module by prefixing your require paths with
-`modules/your_module_name/`.  It's also possible to require files from
-other modules this way too.
-
-The global variables and data stored in the global table is shared by
-all Clusterio modules as well as the scenario, so it's important that
-you use unique names.  It's recommended to prefix the global variables
-and data in the global table that your module has with the name of your
-module.
-
-Because modules can be patched into an existing game you cannot rely on
-the `on_init` callback to be called in Clusterio Modules.  Nor can you
-rely on the `on_configuration_changed` callback, as this is not called
-when level code changes.  The Clusterio Lua API provides the custom
-`on_server_startup` event that can be used as a substitute, see the next
-section.
-
-
-Clusterio Lua API
------------------
-
-Clusterio provides a save patched module as well as a regular Factorio
-mod for interfacing with Clusterio.  This includes tools sending data to
-plugins, script events to listen for, and an item serialization module.
-
-
-### clusterio_api library
-
-**require path**  
-From a module  
-`local clusterio_api = require("modules/clusterio/api")`  
-From a mod  
-`local clusterio_api = require("__clusterio_lib__/api")`
-
-Provides the main interface to Clusterio from within the game.  When
-using the mod version you must call `init` before it'll function
-properly.
-
-#### init
-
-<sub>Mod version only</sub>
-
-Initialize the API.  This should be called from both the `on_init` and
-`on_load` events in your mod, and before this is called certain features
-will not be available, most notably the events table.
-
-#### clusterio_api.events
-
-Table of events raised by clusterio.  If the game is started outside of
-Clusterio then none of these events will be raised.
-
-In the mod version this table does not exist before the `init` function
-is called.
-
-##### on_instance_updated
-
-Raised after the name and id of an instance has been updated.  This may
-occur even if the id and name didn't change.
-
-Event data:
-- `instance_id`: The id of the instance.
-- `instance_name`: the name of the instance.
-
-##### on_server_startup
-
-Raised when Clusterio is starting up the server.  It can be used to
-initialize clusterio related features in a mod, and as a stand-in for
-the `on_init` and `on_configuration_changed` event for modules.  It is
-invoked on the first tick the server runs after the save has been
-patched, before most other events.
-
-Use this event to initialize and and/or migrate the data structures
-you need.  Keep in mind that both mods and Clusterio modules can switch
-from any version to any version so it should be able to handle both
-forwards and backwards migrations gracefully.
-
-#### clusterio_api.send_json(channel, data)
-
-Send json data to Clusterio over the given channel.  The `data` argument
-should be table that can be serialized with `game.table_to_json`.
-Clusterio plugins can listen to channels and will receive an event with
-the data sent here.  See the [Communicating with Factorio
-section](writing-plugins.md#communicating-with-factorio) in the Writing
-Plugins document for more information.
-
-If the game is started outside of Clusterio the data will be sent, but
-since there's no code following stdout to pick it up it will be lost.
-
-**Note**: Payloads greater than 4 MB will cause stuttering in the game.
-
-**Note**: This is not a binary safe way of sending data.  Strings
-embedded into the tables sent must be valid UTF-8 text.
-
-Parameters:
-- `channel`: string identifying which channel to send it on.
-- `data`: table that can be converted to JSON with game.table_to_json
-
-
-### serialize library
-
-**require path**  
-From a module  
-`local serialize = require("modules/clusterio/serialize")`  
-From a mod  
-`local serialize = require("__clusterio_lib__/serialize")`
-
-Serializes inventories and item stacks into a table that in turn can be
-converted into JSON with `game.table_to_json`.  Properly handles the
-extra data for most items.
-
-#### serialize.serialize_equipment_grid(LuaEquipmentGrid)
-
-Returns a table containing a serialized representation of the equipment
-grid passed.
-
-#### serialize.deserialize_equipment_grid(LuaEquipmentGrid, serialized_grid)
-
-Deserialize a previously serialized equipment grid into the target
-LuaEquipmentGrid.  Overwrites all content in the target.
-
-#### serialize.serialize_item_stack(LuaItemStack, destination_table)
-
-Serialize the LuaItemStack passed into the target destination_table.
-The destination_table should be a new empty table.
-
-#### serialize.deserialize_item_stack(LuaItemStack, serialized_stack)
-
-Deserialize a previously serialized item stack into the target
-LuaItemStack.  Overwrites the content of the item stack.
-
-#### serialize.serialize_inventory(LuaInventory)
-
-Returns a table containing a serialized representation of the inventory
-passed.
-
-#### serialize.deserialize_inventory(LuaInventory, serialized_inventory)
-
-Deserialize a previously serialized inventory into the target
-LuaInventory.  Overwrites slots that has content in the serialized
-inventory.
-

-Clusterio Plugins
------------------
-
-The plugin interface is undergoing a major rewrite, and will be
-documented once that is done.  See

-Save Patching
--------------
-
-In order to efficiently get data in and out of running Factorio servers
-and to provide custom interfaces Clusterio uses save
-patching<sup>[1]</sup> to add code to the game.  The save patching is
-based on the built in
-[event_handler](https://github.com/wube/factorio-data/blob/master/core/lualib/event_handler.lua)
-library to Factorio and requires scenarios to be coded specifically for
-it.  Mods on the other hand work without modifications.
-
-<sub>1: Before version 2.0 of Clusterio this was done at runtime
-with a patcher called Hotpatch, but due to the difficulty in supporting
-run time patching and the lack of documentation it was replace it with
-save patching instead.</sub>

-WebSocket protocol
-==================
-
-<sub>This document describes the protocol used between the master and
-slaves, and unless you're developing Clusterio it's probably not going
-to be very useful for you.</sub>
-
-The protocol is built on WebSocket and uses JSON encoded text messages
-to communicate to and from the master server.  These messages contain
-a JSON encoded object with the following three properties:
-
-- seq - integer|null - The sequence number of the message
-- type - string - The type of message
-- data - object - Message data
-
-For the handshake and heartbeats the seq property is null.
-
-
-Handshake
----------
-
-Upon connecting to the WebSocket endpoint the server will respond with a
-`hello` message containing the master server version as the data.  The
-client is then expected to send either `register_*` or a `resume`
-message to set up the connection with the master.  The exact flow is
-described below.
-
-
-### Client connection flow
-
-For a client making a new connecting to the master server the first
-course of action after obtaining a token is to connect with WebSocket to
-the /api/socket endpoint and wait for the server hello.  After the
-hello, the client sends a register\_\* message corresponding to the type
-of the client.  If successful the server will reply with a ready message
-and the connection has been established.  See the flowchart below.
-
-![Client connection flowchart](assets/connection_flow.svg)
-
-If for any reason the connection is closed or lost during the connection
-attempt the process is started over after a random delay, with the
-exception of the connection being closed with a 4003 code which means
-authentication failed and the client should stop trying to connect.  The
-wait for hello and wait for ready states should also have a timeout,
-after which the connection is closed if the hello/reply wasn't received
-in time.
-
-
-### Client reconnection flow
-
-If the connection is lost after the client has received the ready
-message from the server it should attempt a reconnect instead.  This is
-very similar to a new connection, but instead of a register\_\* messsage
-the client sends a resume message and the server replies with a continue
-message if resuming the session was successful.  This continue message
-has sequence number of the last message the master received and the
-client is expected to imediately send all messages from its send buffer
-that occured after the sequence number given.
-
-The server will respond with an invalidate message if resuming the
-session is not possible.  In this case the client should continue from
-the new session state of the connection flow (see the previous section).
-
-![Client reconnection flowchart](assets/reconnection_flow.svg)
-
-Like the connection flow the process starts over after a delay if the
-connection is closed or lost.  The same exception for connection closed
-with 4003 applies as with the connection flow.  Additionally after an
-invalidate message has been received and the connection flow fails, it
-should start over from the connection flow.
-
-
-### Server connection flow
-
-From the master server side new connections and reconnection attempts
-start out the same, a new connection has been made and the server sends
-the hello messoge to the client.  If a vaild register\_\* message is
-received a new connection is set up for the client and the ready message
-is sent in reply.  If a valid resume message is received and the session
-that's attempted to be resumed is active it'll signal that the session
-is resumed with a continue message and the client upon receiving the
-continue message should send the messages from its send buffer from
-after the last\_seq given in the continue message.
-
-If the session token used to resume is not valid it'll send an invalidate
-message and expect the client to continue with a registr\_\* message.  If an
-invalid or unexpected message is received during the handshake the connection
-is closed.  See the flowchart below.
-
-![Client connection flowchart](assets/server_flow.svg)
-
-For authentication failure the connection is closed with code 4003,
-which the connection client should interpret as connecting will never
-succeed and stop trying to reconnect.
-
-
-### Connection tracking and heartbeats
-
-Once connected as indicated by the ready and continue messages from the
-master server the client must start sending heartbeats at the interval
-given in the ready/continue message, and storing messages sent over the
-link in a sending side buffer.  The heartbeats sent must have the seq of
-the last received message on the link and acts as an ack for received
-messages.  The master server also sends heartbeats in the same manner
-and the client should remove messages up to and including the sequence
-number received in the heartbeat from its send buffer.
-
-
-Handshake messages
-------------------
-
-### `hello`
-
-Sent by the master server when the WebSocket connection has been opened.
-
-- version - string - The version of the master, e.g. "2.0.0".
-
-### `register_slave`
-
-Slave handshake for establishing a new connection session.
-
-- token - string - Authentication token.
-- agent - string - Human readable string of the software connecting.
-- version - string - The protocol version of the slave, e.g. "2.0.0".
-- name - string - Name of the slave.
-- id - integer - ID of the slave.
-
-### `register_control`
-
-Control handshake for enstablishing a new connection session.
-
-- token - string - Authentication token.

-- last_seq - integer|null - Last message seq received by the client.
-
-### `invalidate`
-

-
-
-Example handshake
------------------
-
-Server hello after opening the WebSocket.
-
-```json
-{
-    "seq": null,
-    "type": "hello",
-    "data": {
-        "version": "2.0.0"

-        "version": "2.0.0",
-        "name": "Foo",
-        "id": 123

-        "session_token": "xyz.azy.bzy",
-        "heartbeat_interval": 45
-    }
-}
-```
-
-
-Events
-------
-
-Events are messages send in one direction over the link, that the
-receiver is expected to act upon, but not make any replies (for that
-there's [Requests](#requests).  By convention message types ending in
-`*_event` are events.  The data payload of an event consists solely of
-event specific properties.
-
-See [lib/link/messages.js](/lib/link/messages.js) for the recognized
-events and their contents.
-
-
-Requests
---------
-
-Requests are messages which expects a response in return.  They function
-a lot like HTTP requests except that both parties of a connection can
-inniate a request that is expected to be responded to.  By convention
-message types ending in `*_request` are requests, and is expected to be
-replied to with a corresponding `*_response` message.  If an error
-occured while processing the request an error response containing an
-error property in the data payload is sent instead.
-
-See [lib/link/messages.js](/lib/link/messages.js) for the recognized
-requests and their contents.
-
-### `*_response`
-
-- seq - integer - The seq number of the request message.
-- additional properties may be present depending on the type of request.
-
-### `*_response` error
-
-- seq - integer - The seq number of the request message.
-- error - string - Human readable text message describing the error.
-
-
-Graceful shutdown
------------------
-
-To ensure no data is lost when closing the link it's important to
-send connection shutdown request and wait for it to complete before
-closing the WebSocket.  Either party of the link can send this request
-and the party sending the request should be the one that initates the
-close of the WebSocket.
-
-### `connection_shutdown_request`
-
-Request graceful shutdown of the connection.  The receiving party should
-stop tasks that send events and requests over the link and wait for
-pending requests it has over the link to complete, but it should not
-stop responding to requests sent to it.  Only after this process is done
-should the response be sent.
-
-### `connection_shutdown_response`
-
-Signals the shutdown is complete and that the connection can be closed.
-The party that initiatied the shutdown request may still send other
-requests/events over the link to finish its part of the shutdown.
-
-If the error response variant is received it should be logged if
-possible and treated as a success.

-Writing Plugins
-===============

-Plugins for Clusterio are classes written in JavaScript that run under
-Node.js.  The plugin classes have pre-defined hooks that are called

-Plugin Structure
-----------------
-
-The basic file structure of a plugin is the following.
-
-    plugin_name/
-      +- info.js
-      +- package.json
-      +- master.js
-      +- instance.js
-      +- test/
-      |  +- plugin.js
-      +- module/
-         +- module.json
-         +- plugin.lua
-
-The most important file is the `info.js` file.  Without it the plugin
-will not recognized by Clusterio.  Here's an example of it:
-
-    const link = require('lib/link'); // For messages
-
-    module.exports = {
-        name: "foo_frobber",
-        title: "Foo Frobber",
-        description: "Does advance frobnication",
-        version: "0.8.1",
-        instanceEntrypoint: "instance",
-        masterEntrypoint: "master",
-        messages: {
-            /* See below */
-        },
-    };
-
-The following properties are recognized:
-
-**name**:
-    Internal name of the plugin.  Must be the same as the plugin's
-    directory name
-
-**title**:
-    Name of the plugin as shown to users.  Currently not used.
-
-**description**:
-    Brief description of what the plugin does.  Currently not used.
-
-**version**:
-    Semver compatible version string of the plugin.  Currently only
-    servers as the default for the Clusterio module embedded in the
-    plugin, if any.
-
-**instanceEntrypoint**:
-    Path to a Node.js module relative to the plugin directory which
-    contains the InstancePlugin class definition for this plugin.  This
-    is an optional paramater.  A plugin can be for instances only but
-    for it to be able to send any messages to other instances it will
-    still have to be loaded on the master server.
-
-**InstanceConfigGroup**:
-    Subclass of `PluginConfigGroup` to defining the per instance
-    configuration fields for this plugin.  See [Plugin
-    Configuration](#plugin-configuration)
-
-**masterEntrypoint**:
-    Path to a Node.js module relative to the plugin directory which
-    contains the MasterPlugin class definiton for this plugin.  This is
-    an optional parameter.  A plugin can be made that only runs on the
-    master server.
-
-**MasterConfigGroup**:
-    Subclass of `PluginConfigGroup` to defining the master server
-    configuration fields for this plugin.  See [Plugin
-    Configuration](#plugin-configuration)
-
-**messages**:
-    Object with link messages definitions for this plugin.  See guide
-    for [defining link messages](#defining-link-messages) below.
-
-The optional module folder contains a Clusterio module that will be
-patched into the save when the plugin is enabled.  See the section on
-[Clusterio Modules](developing-for-clusterio.md) in the Developing for
-Clusterio document.  The only restriction imposed on modules embedded
-into plugins is that they must be named the same as the plugin.
-
-While there is no standard for how to organize a plugin it's recommended
-to put the MasterPlugin class definition into master.js and the
-InstancePlugin class definition into instance.js.  You can put them into
-whatever file you want (even the same one for both)
-
-For both instanceEntrypoint and masterEntrypoint the path should not end
-with .js and it should use forward slashes for directory sepparators if
-any.
-
-
-Defining the plugin class
--------------------------
-
-The plugin class should derive from its respective base class defined in
-`lib/plugin`.  For example to define a MasterPlugin class the following
-code can be used:
-
-    const plugin = require('lib/plugin');
-
-    class MasterPlugin extends plugin.BaseMasterPlugin {
-        async init() {
-            this.foo = 42;
-            await this.startFrobnication();
-        }
-
-        // ...
-    }
-
-    module.exports = {
-        MasterPlugin,
-    }
-
-For the instance plugin it's exactly the same except "Master" is
-replaced with "Instance".  The available hooks that you can override is
-documented on the base class [in lib/plugin.js](../lib/plugin.js).
-
-It's best to avoid defining a constructor, but if you insist on defining
-one forward all arguments to be the base class.  E.g.:
-
-        constructor(...args) {
-            super(...args);
-
-            // Code here
-        }
-
-The arguments passed may change, and attempting to modify them will
-result in unpredicatable behaviour.  The async init method always called
-immediatly after the constructor so there's little reason to do this.
-
-
-Defining Configuration
-----------------------
-
-Clusterio provides a configuration system that handles storing,
-distributing, editing and validating config fields for you.  You can
-take advantage of it by subclassing `PluginConfigGroup`, setting the
-`groupName` to your plugin name, defining fields on it, finalizing it,
-and passing it as either `MasterConfigGroup` or `InstanceConfigGroup` in
-the `info.js` export.  For example in info.js:
-
-    const config = require("lib/config");
-
-    class MasterConfigGroup extends config.PluginConfigGroup { }
-    MasterConfigGroup.groupName = "foo_frobber";
-    MasterConfigGroup.define({
-        name: "level",
-        description: "Level of frobnication done",
-        type: "number",
-        initial_value: 2,
-    });
-    MasterConfigGroup.finalize();
-
-    module.exports = {
-        ...
-        MasterConfigGroup: MasterConfigGroup,
-    };
-
-Code inside the `MasterPlugin` class will then be able to access the
-level config field through the `Config` object at `this.master.config`,
-for example in the MasterPluginClass:
-
-    async init() {
-        let level = this.master.config.get("foo_frobber.level");
-        console.log("I got a frobnication level of", level);
-    }
-
-The same applies for instance configs, replace "master" with "instance"
-where appropriate.  See [Configuration System](configuration-system.md)
-for more details on how this system works.
-
-
-Communicating with Factorio
----------------------------
-
-For pushing data into Factorio there's RCON which lets you send
-arbitrary Lua command to invoke whatever code you want in the game.
-This is done by calling sendRcon method on the instance's server object.
-For example:
-
-    async onStart() {
-        let response = await this.instance.server.sendRcon(
-            "/sc rcon.print('data')"
-        );
-
-        // Do stuff with response.
-    }
-
-
-Because data into Factorio is streamed at a rate of 3-6 kB/s by default
-it is recommended to avoid sending large commands as much as possible,
-and to strip down the data on the ones you send to only what's strictly
-necessary.  You can have lua code injected into the game via the module
-system and call that from RCON to avoid having to send code through the
-commands.
-
-For getting data out from Factorio there's both RCON and the `send_json`
-API of the Clusterio module.  Returning data via RCON is prefered if the
-action is initiated from the Node.js side.  The `send_json` API allows
-sending JSON payloads on channels that plugins can listen to.  From a
-plugin you listen for an event named ipc-channel_name in order to get
-data sent by `send_json`.  For example in the plugin code:
-
-    async init() {
-        this.instance.server.on('ipc-my_plugin_foo', content =>
-            this.handleFoo(content).catch(err => console.log(
-                "Error handling foo:", foo
-            ))
-        );
-    }
-
-    async handleFoo(content) {
-        // Do stuff with content
-    }
-
-And then in the module for the plugin:
-
-    local clusterio_api = require('modules/clusterio/api')
-
-    -- inside some event handler
-    clusterio_api.send_json('my_plugin_foo', { data = 123 })
-
-It's recommended to either use the plugin name as the channel name or to
-prefix the channel name with the name of the plugin if you need multiple
-channels.  It's also important to catch any errors that might occur as
-they will otherwise be propogated to the instance code and kill the
-server.
-
-Data out from Factorio does not have the same limits as data into
-Factorio, RCON responses can be in 100kB range without causing issues,
-and payloads to the `send_json` API can be in the 4MB range provided the
-server has a fast enough storage system.
-
-**Note:** both `send_json` and RCON can operate out of order.  For
-`send_json` it's possible that payloads greater than 4kB are received
-after payloads that was sent at a later point in time.  For RCON,
-commands longer than 50 characters may end up being executed after
-shorter commands sent after it.

-
-Defining Link Messages
-----------------------
-
-You will most likely have to communicate with the master or other
-instances in your plugin for it to do anything useful.  For this there's
-a WebSocket communication channel established between the slaves and the
-master server that plugins can define their own messages to send over
-it.  This channel is bi-directional and all messages send over it are
-validated with a JSON schema (see [this guide][guide] for an
-introduction to writing JSON schema.)
-
-[guide]: https://json-schema.org/learn/getting-started-step-by-step.html
-
-There are currently two kinds of messages that can be defined.  Events
-and requests.  Events are simple one way notifications that invoke a
-handler on target it's sent to.  Requests are pairs of request and
-response messages where the request is sent to the target and the
-response is the reply back from the target.  The requests are similar to
-HTTP requests only that both parties of a link may innitiate one.
-
-
-### Defining Events
-
-Events are defined as properties of the messages object exported by
-`info.js` that map to instances of the `Event` class from `lib/link`.
-The name of the property correspond to the handler invoked on the plugin
-class.  The Event constructor takes an object of properties that define
-the event, for example the following could be defined in `info.js`:
-
-    messages: {
-        startFrobnication: new link.Event({
-            type: 'foo_frobber:start_frobnication',
-            links: ['master-slave', 'slave-instance'],
-            forwardTo: 'instance',
-            eventProperties: {
-                "frobnication_type": { type: "string" },
-            },
-        }),
-    },
-
-This specifies an event that can be sent from the master to a slave,
-and from a slave to an instance.  And that the event must contain the
-property `frobnication_type` with a string value in the data payload.
-It will also be forwarded by slaves to a specific instance.
-
-The following properties are recognized by the Event constructor:
-
-**type**:
-    The message type sent over the wire.  This can be any string but
-    it must be unique across all plugins and it's recommended that it is
-    of format `plugin_name:message_name`.  The suffix `_event` will be
-    appened to the type.
-
-**links**:
-    An array of strings describing which links this event can be sent
-    over.  Direction matters, `'master-slave'` means the event can be
-    sent from the master to slave, but can't be sent back the other way
-    unless `'slave-master'` is also present in the links array.
-
-**forwardTo**:
-    Target to forward event to.  Can be either `'master'` to indicate a
-    slave should forward it to the master server or `'instance'` to
-    indicate it should be forwarded to the instances specified by the
-    `instance_id` event property.  This works by using a default handler
-    for the event at the links that forward it.
-
-**broadcastTo**:
-    Target to broadcast this message towards.  Currently only
-    `'instance'` is supported and means the event will be broadcast to
-    all instances downstream of the target it's sent to, but not back
-    from where it came from.  This means that sending an event to a
-    slave from an instance will cause it to be broadcast to all
-    instances of that slave except for the instance it came from.
-
-**eventProperties**:
-    Object with properties mapping to a JSON schema of that property
-    that specifies what's valid to send in the event.  This is
-    equivalent to using the `properties` keyword in JSON schema except
-    that the properties specified are implicitly required and additional
-    properties are not allowed.  See [this guide][guide] for an
-    introduction to writing JSON schemas
-
-The forwardTo and broadcastTo can be combined such that specifying
-`'master'` as the forwardTo value and `'instance'` as the broadcastTo
-value will cause the event to be broadcast to all instances in the
-cluster.  For this to work you will need to specify instance-slave,
-slave-master and master-slave, slave-instance as the links.
-
-Keep in mind when forwarding events that if the target an event is being
-forwarded to is not online the event will be dropped.  If you need a
-confirmation that the message was received use a request.
-
-
-### Definining Requests
-
-Requests are defined as properties of the messages object exported by
-`info.js` that map to instances of the `Request` class from `lib/link`.
-The name of the property correspond to the handler invoked on the plugin
-class.  The Request constructor takes an object of properties that define
-the event, for example the following could be defined in `info.js`:
-
-    messages: {
-        reportFrobnication: new link.Request({
-            type: 'foo_frobber:report_frobnication',
-            links: ['master-slave', 'slave-instance'],
-            forwardTo: 'instance',
-            requestProperties: {
-                "verbosity": { type: "integer" },
-            },
-            responseProperties: {
-                "report": {
-                    type: "array",
-                    items: { type: "string" },
-                },
-            },
-        }),
-    },
-
-This specifies a request that can be sent from the master to a slave,
-and from a slave to an instance.  The request data must contain the
-property `verbosity` with an integer number as the value as well as the
-`instance_id` property (implied by `forwardTo: 'instance'`), and the
-response sent must contain a `report` property mapping to an array of
-strings.  When received by a slave it will also be forwarded to the
-instance specified by `instance_id`.
-
-The following properties are recognized by the Request constructor:
-
-**type**:
-    The message type sent over the wire.  This can be any string but
-    it must be unique across all plugins and it's recommended that it is
-    of format `plugin_name:message_name`.  The suffix `_request` will be
-    appened to the type for the request message sent, and the suffix
-    `_response` will be appended to the type for the response.
-
-**links**:
-    An array of strings describing which links this request can be sent
-    over.  Direction matters, `'master-slave'` means the request can be
-    sent from the master to slave and the slave can reply to the master,
-    but the slave can't sent a request to the master unless
-    `'slave-master'` is also present in the links array.
-
-**forwardTo**:
-    Target to forward request to.  Can be either `'master'` to indicate
-    a slave should forward it to the master server when receiving it
-    from an instance or `'instance'` to indicate it should be forwarded
-    to the instances specified by the `instance_id` request property.
-    This works by using a default handler for the request at the links
-    that forward it.
-
-**requestProperties**:
-    Object with properties mapping to a JSON schema of that property
-    that specifies what's valid to send in the request.  This is
-    equivalent to using the `properties` keyword in JSON schema except
-    that the properties specified are implicitly required and additional
-    properties are not allowed.  See [this guide][guide] for an
-    introduction to writing JSON schemas
-
-**responseProperties**:
-    Same as the requestProperties only for the response sent back by the
-    target.
-
-
-Sending Link Messages
----------------------
-
-Link messages are sent by calling the `.send()` method on the
-Event/Request instance with the link you want to send it over and the
-data to send.  For instance plugins the link is the instance itself
-which is accessible through the `.instance` property on the plugin.  The
-`.info` property of the plugin class exposes the data exported from the
-plugin's `info.js` module.  In other words:
-
-    // In an InstancePlugin class
-    async frobnicate() {
-        this.info.messages.exampleEvent.send(this.instance, { foo: "bar" });
-    }
-
-For the Request class the send method is async and returns the response
-data received from the target it was sent to, or throws an error if the
-request failed.
-
-
-Collecting Statistics
----------------------
-
-Clusterio comes with it's own Prometheus client implementation, one part
-due to Not Invented Here and another part due to collectors in
-prom-client being difficult to get to work nicely with collecting data
-from plugins optionally loaded at runtime on different computers.
-
-In its simplest form collecting data from a plugins consists of defining
-the metric and updating it somewhere in the plugin code.  For example:
-
-    const { Counter } = require('lib/prometheus');
-
-    const fooMetric = new Counter(
-        'clusterio_foo_frobber_foo_metric', "Measures the level of foo",
-    );
-
-    // Somewhere in the master plugin code
-    fooMetric.inc();
-
-This works for master plugins, and the metric will be automatically
-available through the /metric HTTP endpoint.  It's recommended that
-plugin metrics follow `clusterio_<plugin_name>_<metric_name>` as the
-naming scheme.
-
-For metrics that are per-instance you must define an `instance_id` label and
-set it accordingly, for example:
-
-    const { Counter } = require('lib/prometheus');
-
-    const barMetric = new Gauge(
-        'clusterio_foo_frobber_bar_metric', "Bar instance level",
-        { labels: ['instance_id'] }
-    );
-
-    // Somewhere in the instance plugin code
-    barMetric.labels(String(this.instance.config.get("instance.id"))).set(someValue);
-
-Metrics are automatically registered to the default registry, and this
-default registry is automatically polled by the master server on slaves.
-This means that it's important that you place the definition of the
-metric at module level so that it's not created more than once over the
-lifetime of a slave.  Since the metrics remember their values and would
-continue to be exported after an instance is shutdown there's code at
-instance shutdown that removes all the values where the `instance_id`
-label matches the id of the instance shut down.
-
-For statistics you need to update on collection there's an `onMetrics`
-hook on both master and instance plugins that is runned before the
-metrics in the default registry is collected.
