mod_muc_rtbl: also filter messages This was a bit tricky because we don't want to run the JIDs through SHA256 on each message. Took a while to come up with this simple plan of just caching the SHA256 of the JIDs on the occupants. This will leave some dirt in the occupants after unloading the module, but that should be ok; once they cycle the room, the hashes will be gone. This is direly needed, otherwise, there is a tight race between the moderation activities and the actors joining the room.

description: HTTP File Upload
labels: 'Stage-Alpha'

Introduction
============

This module implements [XEP-0363], versions 0.2 and 0.3, which let
clients upload files over HTTP.

Configuration
=============

mod\_http\_upload relies on Prosodys HTTP server and mod\_http for
serving HTTP requests. See [Prosodys HTTP server documentation][doc:http]
for information about how to configure ports, HTTP Host names etc.

The module can be added as a new Component definition:

``` {.lua}
Component "upload.example.org" "http_upload"
```

It should **not** be added to modules_enabled.

## Discoverability

Prosody makes subdomains of your VirtualHosts easily discoverable by
clients. To make the component discoverable by other hosts where the
component is **not a subdomain** of the VirtualHost, you can use
[`disco_items`][doc:modules:mod_disco#configuration].

``` {.lua}
VirtualHost "foo.example.org"
disco_items = {
    { "upload.example.com" },
}
```

## Access

You may want to give upload access to additional entities such as components
by using the `http_upload_access` config option.

``` {.lua}
http_upload_access = {"gateway.example.com"};
```

Limits
------

### Max size

A maximum file size can be set by:

``` {.lua}
http_upload_file_size_limit = 123 -- bytes
```

Default is 1MB (1024\*1024).

This can not be set over the value of `http_max_content_size` (default 10M).
Consider [mod_http_upload_external] instead of attempting to increase
this limit.

### Max age

Files can be set to be deleted after some time:

``` lua
http_upload_expire_after = 60 * 60 * 24 * 7 -- a week in seconds
```

Expired files are deleted when a new upload slot is requested,

A command exists to invoke expiry:

```
prosodyctl mod_http_upload expire [list of users or hosts]
```

### User quota

A total maximum size of all uploaded files per user can be set by:

``` lua
http_upload_quota = 1234 -- bytes
```

A request for a slot that would take an user over quota is denied.

Path
----

By default, uploaded files are put in a sub-directory of the default
Prosody storage path (usually `/var/lib/prosody`). This can be changed:

``` {.lua}
http_upload_path = "/path/to/uploaded/files"
```

Compatibility
=============

Works with Prosody 0.11.x and later.

In Prosody 0.12 and later, consider switching to [mod_http_file_share](https://prosody.im/doc/modules/mod_http_file_share)
which is distributed with Prosody. You can migrate existing files using
[mod_migrate_http_upload](https://modules.prosody.im/mod_migrate_http_upload.html).
