// Thread management and startup/shutdown: |
|
// |
|
// The network-processing threads are all part of a thread group |
|
// created by AppInit() or the Qt main() function. |
|
// |
|
// A clean exit happens when StartShutdown() or the SIGTERM |
|
// signal handler sets fRequestShutdown, which triggers |
|
// the DetectShutdownThread(), which interrupts the main thread group. |
|
// DetectShutdownThread() then exits, which causes AppInit() to |
|
// continue (it .joins the shutdown thread). |
|
// Shutdown() is then |
|
// called to clean up database connections, and stop other |
|
// threads that should only be stopped after the main network-processing |
|
// threads have exited. |
|
// |
|
// Note that if running -daemon the parent process returns from AppInit2 |
|
// before adding any threads to the threadGroup, so .join_all() returns |
|
// immediately and the parent exits from main(). |
|
// |
|
// Shutdown for Qt is very similar, only it uses a QTimer to detect |
|
// fRequestShutdown getting set, and then does the normal Qt |
|
// shutdown thing. |
