mod_rest: Catch and log errors in callback promise chain From the code it looks like it should be possible to reply to an error stanza, but it did not. Turns out I was saved by my local developer mode module which throws errors if an attempt is made to create an errror reply to an error stanza. However nothing collects this error from the promise, so all I got was confusion.

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, use
[`disco_items`][doc:modules:mod_disco#configuration].

``` {.lua}
VirtualHost "foo.example.org"
disco_items = {
    { "upload.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 0.9.x and later.
