mod_muc_markers: Prevent any markers from reaching the archive, even if untracked Original intention was to leave alone things that this module isn't handling. However markers in archives are just problematic without more advanced logic about what is markable and what is not. It also requires a more advanced query in mod_muc_rai to determine the latest markable message instead of the latest archived message. I'd rather keep the "is archivable" and "is markable" definition the same for simplicity. I don't want to introduce yet another set of rules for no reason. No markers in MAM.

# Introduction

This module externalizes MUC authorization via HTTP.  
Whenever a user wants to join a MUC, an HTTP GET request is made to `authorization_url`
with the user bare jid (`userJID`) and the MUC jid (`mucJID`) as GET parameters.  
Example:  
`https://www.prosody.im/users/can-join/?userJID=romeo@example.com&mucJID=teaparty@chat.example.com`

This allows an external service to decide whether a user is authorized to join a MUC or not.  

When a user is authorized to join a MUC, this module expects the following JSON payload:
```
{
    allowed: true,
    error: "",
}
```
Otherwise, either the user not being authorized or some failure in the external service:
```
{
    allowed: false,
    error: "Some error message to be displayed in this module's logs",
}
```

# Configuring

## Enabling

``` {.lua}
Component "rooms.example.net" "muc"

modules_enabled = {
    "muc_http_auth";
}

```


## Settings

|Name |Description |Default |
|-----|------------|--------|
|muc_http_auth_url| URL of the external HTTP service to which send `userJID` and `mucJID` in a GET request | "" |
|muc_http_auth_enabled_for| List of MUC names (node part) to enable this module for | nil |
|muc_http_auth_disabled_for| List of MUC names (node part) to disable this module for | nil |
|muc_http_auth_insecure| Disable certificate verification for request. Only intended for development of the external service. | false |
|muc_http_auth_authorization_header| Value of the Authorization header if requested by the external HTTP service. Example: `Basic dXNlcm5hbWU6cGFzc3dvcmQ=`| nil |


This module can be enabled/disabled for specific rooms. Only one of the following settings must be set.
```
-- muc_http_auth_enabled_for = {"teaparty"}
-- muc_http_auth_disabled_for = {"teaparty"}
```
If none is set, all rooms in the MUC component will have this module enabled.

Note: Use the node part of the MUC jid for these lists. Example:  

Wrong:
`muc_http_auth_enabled_for = {"teaparty@rooms.example.net"}`

Correct:
`muc_http_auth_enabled_for = {"teaparty"}`
