When certain "interesting" things happen during the lifetime of the process, gevent will "publish" an event (an object). That event is delivered to interested "subscribers" (functions that take one parameter, the event object). Higher level frameworks may take this foundation and build richer models on it. :mod:`zope.event` will be used to provide the functionality of `notify` and `subscribers`. See :mod:`zope.event.classhandler` for a simple class-based approach to subscribing to a filtered list of events, and see `zope.component `_ for a much higher-level, flexible system. If you are using one of these systems, you generally will not want to directly modify `subscribers`. .. versionadded:: 1.3b1 .. versionchanged:: 23.7.0 Now uses :mod:`importlib.metadata` instead of :mod:`pkg_resources` to locate entry points. )absolute_import)division)print_function) subscribersIEventLoopBlockedEventLoopBlockedIMemoryUsageThresholdExceededMemoryUsageThresholdExceededIMemoryUsageUnderThresholdMemoryUsageUnderThresholdIPeriodicMonitorThread"IPeriodicMonitorThreadStartedEvent!PeriodicMonitorThreadStartedEventIGeventPatchEventGeventPatchEventIGeventWillPatchEvent DoNotPatchGeventWillPatchEventIGeventDidPatchEventIGeventWillPatchModuleEventGeventWillPatchModuleEventIGeventDidPatchModuleEventGeventDidPatchModuleEventIGeventWillPatchAllEventGeventWillPatchAllEvent"IGeventDidPatchBuiltinModulesEvent!GeventDidPatchBuiltinModulesEventIGeventDidPatchAllEventGeventDidPatchAllEventN) Interface) Attribute) implementer)r)notifycCst|ddlm}ddl}|jdddkr|j|jd}n|}|}tdd||jdD}|D] }| }||q5dS) Nr)metadata) )groupcss|]}|VqdSN).0epr)r)W/var/www/html/backend_erp/backend_erp_env/lib/python3.10/site-packages/gevent/events.py s  z/notify_and_call_entry_points..r)) r" importlibr#sys version_info entry_pointsENTRY_POINT_NAMEsetgetload)eventr#r/r1ep_dict__traceback_info__plugin subscriberr)r)r,notify_and_call_entry_pointsis    r;c@eZdZdZddZdS)r zY The contract for the periodic monitoring thread that is started by the hub. cCdS)a8 Schedule the *function* to be called approximately every *period* fractional seconds.
