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.

--- summary: Collect statistics on rate of log messages ... Introduction ============ If you ever wanted to collect statistics on the number of log messages, this is the module for you! Setup ===== After [installing the module](https://prosody.im/doc/installing_modules) and adding it to modules\_enabled as most other modules, you also need to add it to your logging config: ``` {.lua} log = { -- your other log sinks info = "/var/log/prosody/prosody.log" -- add this: { to = "measure" }; } ``` Then log messages will be counted by [statsmanager](https://prosody.im/doc/developers/core/statsmanager). Compatibility ============= Reqires Prosody 0.10 or above.
