示例1: _exit_function
# 需要导入模块: from multiprocessing import process [as 别名]
# 或者: from multiprocessing.process import active_children [as 别名]
def _exit_function(info=info, debug=debug, _run_finalizers=_run_finalizers,
active_children=active_children,
current_process=current_process):
# We hold on to references to functions in the arglist due to the
# situation described below, where this function is called after this
# module's globals are destroyed.
global _exiting
if not _exiting:
_exiting = True
info('process shutting down')
debug('running all "atexit" finalizers with priority >= 0')
_run_finalizers(0)
if current_process() is not None:
# We check if the current process is None here because if
# it's None, any call to ``active_children()`` will raise
# an AttributeError (active_children winds up trying to
# get attributes from util._current_process). One
# situation where this can happen is if someone has
# manipulated sys.modules, causing this module to be
# garbage collected. The destructor for the module type
# then replaces all values in the module dict with None.
# For instance, after setuptools runs a test it replaces
# sys.modules with a copy created earlier. See issues
# #9775 and #15881. Also related: #4106, #9205, and
# #9207.

# 或者: from multiprocessing.process import active_children [as 别名]

# module's globals are destroyed.

if current_process() is not None:
# NB: we check if the current process is None here because if
# it's None, any call to ``active_children()`` will throw an
# AttributeError (active_children winds up trying to get
# attributes from util._current_process). This happens in a
# variety of shutdown circumstances that are not well-understood
# because module-scope variables are not apparently supposed to
# be destroyed until after this function is called. However,
# they are indeed destroyed before this function is called. See
# issues 9775 and 15881. Also related: 4106, 9205, and 9207.
