pause and resume of proxy with inactivity timeout causes proxy to be immediately deleted after successful resume #101
Description
example case in testing backend support for pause and resume on snowpark container services service suspend resume.
if i have a inactivity timeout set in shiny proxy for say 5 minutes.
i pause my app/proxy. service in spcs suspends
go back to app screen or admin screen.
watch inactivity timeout exceed 5 minutes.
app remains in paused state not deleted as expected.
open the app again, it resumes as expected.
immediately app is deleted due to inactivity.
heartbeat-rate: 10000
heartbeat-timeout: 300000
suggested fix.
ProxyService.java
import eu.openanalytics.containerproxy.service.heartbeat.HeartbeatService;
@Inject
@Lazy
private HeartbeatService heartbeatService;
public Command resumeProxy(Authentication user, Proxy proxy, Map<String, String> parameters) {
...
Proxy result = startOrResumeProxy(user, parameterizedProxy, null);
if (result != null) {
slog.info(result, "Proxy resumed");
applicationEventPublisher.publishEvent(new ProxyResumeEvent(result));
// Reset heartbeat so inactivity timer does not immediately stop the proxy after resume
heartbeatService.heartbeatReceived(HeartbeatService.HeartbeatSource.INTERNAL, result, null);
// final check to see if the app was stopped
cleanupIfPendingAppWasStopped(result);
}
...
}

Hi, thanks for opening this issue. I'll have to look into this. I think for now you workaround is okay.
