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: Keepalive s2s connections ... Introduction ============ This module periodically sends [XEP-0199] ping requests to remote servers to keep your connection alive. Configuration ============= Simply add the module to the `modules_enabled` list like any other module. By default, all current s2s connections will be pinged periodically. To ping only a subset of servers, list these in `keepalive_servers`. The ping interval can be set using `keepalive_interval`. If no response to the ping has been received in about 10 minutes (or `keepalive_timeout` seconds) the s2s connections are closed. ``` lua modules_enabled = { ... "s2s_keepalive" } keepalive_servers = { "conference.prosody.im"; "rooms.swift.im" } keepalive_interval = 90 -- (in seconds, default is 60 ) keepalive_timeout = 300 -- (in seconds, default is 593 ) ``` Compatibility ============= ------- ----------------------- 0.11 Works 0.10 Works 0.9 Works ------- -----------------------
