mod_invites_register_api: Use set_password() for password resets
Previously the code relied on the (weird) behaviour of create_user(), which
would update the password for a user account if it already existed. This has
several issues, and we plan to deprecate this behaviour of create_user().
The larger issue is that this route does not trigger the user-password-changed
event, which can be a security problem. For example, it did not disconnect
existing user sessions (this occurs in mod_c2s in response to the event).
Switching to set_password() is the right thing to do

--- labels: - 'Stage-Stable' summary: Log warning when event handlers take too long ... Introduction ============ Most activities in Prosody take place within our built-in events framework, for example stanza processing and HTTP request handling, authentication, etc. Modules are able to execute code when an event occurs, and they should return as quickly as possible. Poor performance (e.g. slow or laggy server) can be caused by event handlers that are slow to respond. This module is able to monitor how long each event takes to be processed, and logs a warning if an event takes above a certain amount of time, including providing any details about the event such as the user or stanza that triggered it. The aim is to help debug why a server may not be as responsive as it should be, and ultimately which module is to blame for that. Configuration ====================== There is a single configuration option: ``` -- Set the number of seconds an event may take before -- logging a warning (fractional values are ok) log_slow_events_threshold = 0.5 ``` Metrics ======= In addition to the log messages, a new 'slow_events' metric will be exported to your configured stats backend (if any). Compatibility ------------- ------- -------------- trunk Works 0.10 Works 0.9 Doesn't work 0.8 Doesn't work ------- --------------
