我们从Python开源项目中,提取了以下2个代码示例,用于说明如何使用struct._clearcache()。
def dash_R_cleanup(fs, ps, pic, zdc, abcs): import gc, copy_reg import _strptime, linecache dircache = test_support.import_module('dircache', deprecated=True) import urlparse, urllib, urllib2, mimetypes, doctest import struct, filecmp from distutils.dir_util import _path_created # Clear the warnings registry, so they can be displayed again for mod in sys.modules.values(): if hasattr(mod, '__warningregistry__'): del mod.__warningregistry__ # Restore some original values. warnings.filters[:] = fs copy_reg.dispatch_table.clear() copy_reg.dispatch_table.update(ps) sys.path_importer_cache.clear() sys.path_importer_cache.update(pic) try: import zipimport except ImportError: pass # Run unmodified on platforms without zipimport support else: zipimport._zip_directory_cache.clear() zipimport._zip_directory_cache.update(zdc) # clear type cache sys._clear_type_cache() # Clear ABC registries, restoring previously saved ABC registries. for abc, registry in abcs.items(): abc._abc_registry = registry.copy() abc._abc_cache.clear() abc._abc_negative_cache.clear() # Clear assorted module caches. _path_created.clear() re.purge() _strptime._regex_cache.clear() urlparse.clear_cache() urllib.urlcleanup() urllib2.install_opener(None) dircache.reset() linecache.clearcache() mimetypes._default_mime_types() filecmp._cache.clear() struct._clearcache() doctest.master = None try: import ctypes except ImportError: # Don't worry about resetting the cache if ctypes is not supported pass else: ctypes._reset_cache() # Collect cyclic trash. gc.collect()
