We really need to rename this option to something more comprehensible. It is only used for two actions in the SSSD code: 1) When sending a heartbeat ping to the monitor's child processes, if the child does not respond with it's pong within the sbus_timeout, it is considered to be hung. 2) When the monitor wants to order a child to shutdown (when the SSSD is shutting down, or when config changes are pushed live (future feature), this timeout is used to determine whether the child has received the shutdown command. So perhaps we should change the name to something like heartbeat_timeout and set the default to an explicit value. Opinions? A bit of history: Originally, we had intended this to be the default timeout for all inter-process communication in the SSSD, so that's why it was named sbus_timeout. As development progressed, we started deciding that nearly every separate call needed its own timeout value, and this setting became increasingly less usefully defined. _______________________________________________ sssd-devel mailing list sssd-devel@lists.fedorahosted.org https://fedorahosted.org/mailman/listinfo/sssd-devel - -- Stephen Gallagher RHCE 804006346421761 Delivering value year after year.
