pyqt application performing updates -


i have pyqt application ready release. it's first attempt on gui thing bare me. works pretty , have 1 more thing wrap up. love software updates itself:

  • check url new version;
  • new version found;
  • notify user of updates (click) → update.

the problem don't know how perform update. check, find new version, download , must close application , execute installer of new version. if close can't execute else, if execute installer can't close application.

based on user choices program downloads , installs third party software needs same thing: close before install program, restart after install program.

after downloading installer newer version, can use atexit.register() os.exec*() run installer, e.g. atexit.register(os.execl, "installer.exe", "installer.exe"). make installer start when application exit. application exit after os.exec*() call, no race condition occur.
