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: - 'Stage-Merged' - 'Type-Storage' - ArchiveStorage summary: 'Simple memory-only storage module' ... Introduction ============ This module acts as a normal storage module for Prosody, but saves all data in memory only. All data is lost when the server stops. This makes it useful for testing, or certain specialized applications. Details ======= Because the accounts store will always begin empty, it is mostly useful combined with an authentication plugin which doesn't use Prosody's storage API, or with [mod\_auth\_any](mod_auth_any.html), or you can create user accounts manually each time the server starts. Compatibility ============= ----- ------- 0.9 Works ----- -------
