mod_http_muc_log: Fix exception on lack of trailing slash in room path A request to /room leads to the match call returning nil which in turn calls nodeprep(nil). In Prosody 0.11.x this does nothing and simply returns the nil, while in 0.12 it is an error. Now it redirects to the calendar view at /room/ - even for non-existant rooms. Discovered at a deployment with http_paths = { muc_log = "/" } and requests to /robots.txt and similar, which now result in a uses redirect before returning 404.

summary: prosodyctl cross storage driver migration tool
...

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

This module adds a command to `prosodyctl` for copying data between
storage drivers.

Usage
=====

    prosodyctl mod_migrate example.com <source-store>[-<store-type>] <target-driver> [users]*

`<source-store>` would be e.g. `accounts` or `private`. To migrate
archives, the optional suffix `<store-type>` would be set to `archive`,
so e.g. `archive2-archive` or `muc_log-archive`. Multiple stores can be
given if separated by commas.

`<target-driver>` is the storage driver to copy data to, sans the
`mod_storage_` prefix.

`mod_migrate` tries to request a list of users from `usermanager`, but
this does not always work. If so, you can supply usernames as arguments
after the target driver.

The process is something like this:

1.  Decide on the future configuration and add for example SQL
    connection details to your prosody config, but don't change the
    `store` option yet.
2.  With Prosody shut down, run
    `prosodyctl mod_migrate example.com accounts sql`
3.  Repeat for each store, substituting 'accounts'. E.g. vcards,
    private...
4.  Change the [`storage` configuration](https://prosody.im/doc/storage)
    to use the new driver.
5.  Start prosody again.

Examples
========

``` sh
prosodyctl mod_migrate example.com accounts,roster,private,vcard sql
```

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

Should work with 0.8 and later.
