The event loop cycles too often to use verto_run_once() as a way to deal with marking activity. So revert to using verto_run() and set the termination handler once for now. Signed-off-by: Simo Sorce <[email protected]>
Refactor init functions and move them in the appropriate file. Signed-off-by: Simo Sorce <[email protected]>
These are functions that are used to manage the proxy own main process after initialization. Store in their own file so the scope is clear. Signed-off-by: Simo Sorce <[email protected]>
Self termination need to happen only when gssproxy is idle for a certina amount of time. However due to non material activity the gssproxy performs through the verto event handler we need to actively measure ideling rather than depend on things like verto_idle. Ad an accounting function to our socket handler. This now allows us to collect some interesting statistics as well as reset the idle handler when there is actual activity ongoing. We reset the handler only upon receiving data from a client, as that indicates a requested activity. Writes happen only as reposnses and are considered part of a single activity event together with the read that caused the idel handler reset. Signed-off-by: Simo Sorce <[email protected]>
Currently just checks that initialization and self termination actually happened. Signed-off-by: Simo Sorce <[email protected]>

Manual testing works + added basic testing for self termination in userproxytest.c |

Self termination was not happening if the timeout was larger than about 1 minute, due to the event loop self management which makes it return to the calling function regularly.
In order to ignore unimportnat events that wake up the event loop it means we cannot measure idleness from the event loop general activity but we need to do so via measuring actual significant events.
Actual activity happens when clients make requests, so use the socket reader events as signal to reset the idler event.
While there also gather some statistics that can be printed ad debug level 1 (INFO).
