我们从Python开源项目中，提取了以下9个代码示例，用于说明如何使用pyinotify.IN_ATTRIB。
def inotify_code_changed(): """ Checks for changed code using inotify. After being called it blocks until a change event has been fired. """ class EventHandler(pyinotify.ProcessEvent): modified_code = None def process_default(self, event): if event.path.endswith('.mo'): EventHandler.modified_code = I18N_MODIFIED else: EventHandler.modified_code = FILE_MODIFIED wm = pyinotify.WatchManager() notifier = pyinotify.Notifier(wm, EventHandler()) def update_watch(sender=None, **kwargs): if sender and getattr(sender, 'handles_files', False): # No need to update watches when request serves files. # (sender is supposed to be a django.core.handlers.BaseHandler subclass) return mask = ( pyinotify.IN_MODIFY | pyinotify.IN_DELETE | pyinotify.IN_ATTRIB | pyinotify.IN_MOVED_FROM | pyinotify.IN_MOVED_TO | pyinotify.IN_CREATE | pyinotify.IN_DELETE_SELF | pyinotify.IN_MOVE_SELF ) for path in gen_filenames(only_new=True): wm.add_watch(path, mask) # New modules may get imported when a request is processed. request_finished.connect(update_watch) # Block until an event happens. update_watch() notifier.check_events(timeout=None) notifier.read_events() notifier.process_events() notifier.stop() # If we are here the code must have changed. return EventHandler.modified_code

Also # it's quite buggy and the API is a mess.
