mod_cloud_notify_encrypted: Ensure body substring remains valid UTF-8
The `body:sub()` call risks splitting the string in the middle of a
multi-byte UTF-8 sequence. This should have been caught by util.stanza
validation, but that would have caused some havoc, at the very least causing
the notification to not be sent.
There have been no reports of this happening. Likely because this module
isn't widely deployed among users with languages that use many longer UTF-8
sequences.
The util.encodings.utf8.valid() function is O(n) where only the last
sequence really needs to be checked, but it's in C and expected to be fast.

--- labels: - 'Type-Auth' - 'Stage-Stable' summary: SQL Database authentication module ... Introduction ============ Allow client authentication to be handled by an SQL database query. Unlike mod\_storage\_sql (which is supplied with Prosody) this module allows for custom schemas (though currently it is required to edit the source). Configuration ============= As with all auth modules, there is no need to add this to modules\_enabled. Simply add in the global section, or for the relevant hosts: authentication = "sql" This module reuses the database configuration of [mod\_storage\_sql](http://prosody.im/doc/modules/mod_storage_sql) (the 'sql' option), which you can set even if you are not using SQL as Prosody's primary storage backend. The query is currently hardcoded in the module, so you will need to edit the module to change it. The default query is compatible with jabberd2 DB schema. Compatibility ============= ----- ------- 0.8 Works ----- -------
