importlib.find_loader

by Thomas Heller

In Python3.3, I thought that every loaded module has a __loader__ attribute. Apparently this is not the case for a few builtin modules: Python 3.3.0 (v3.3.0:bd8afb90ebf2, Sep 29 2012, 10:57:17) [MSC v.1600 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import importlib >>> >>> def bug(): ... for name in list(sys.modules.keys()): ... try: ... importlib.find_loader(name) ... except Exception as details: ... print(name, type(details), details) ... >>> bug() _frozen_importlib <class 'AttributeError'> 'module' object has no attribute '__loader__' builtins <class 'AttributeError'> 'module' object has no attribute '__loader__' signal <class 'AttributeError'> 'module' object has no attribute '__loader__' importlib._bootstrap <class 'AttributeError'> 'module' object has no attribute '__loader__' >>> However, the importlib docs talk about a ValueError instead of the AttributeError that I see above: > Find the loader for a module, optionally within the specified path. > If the module is in sys.modules, then sys.modules[name].__loader__ > is returned (unless the loader would be None, in which case > ValueError is raised). Is this a bug? Thomas

issue17097:baseManager serve_client() not check EINTR when recv request

by Royce Lv

Hi All, We create our customised manager which will fork child process with baseManager. Because we registered SIGCHLD to reap the zombie for manager, we found this causes baseManager raise RemoteError when called twice.(Test script attached.) After look at baseManager.py we found recv() in handling the request has been interrupted by comming SIGCHLD, not retry recv(), but raise to client side directly. try: methodname = obj = None request = recv()<------------------this line been interrupted by SIGCHLD ident, methodname, args, kwds = request obj, exposed, gettypeid = id_to_obj[ident] if methodname not in exposed: raise AttributeError( 'method %r of %r object is not in exposed=%r' % (methodname, type(obj), exposed) ) function = getattr(obj, methodname) try: res = function(*args, **kwds) except Exception, e: msg = ('#ERROR', e) else: typeid = gettypeid and gettypeid.get(methodname, None) if typeid: rident, rexposed = self.create(conn, typeid, res) token = Token(typeid, self.address, rident) msg = ('#PROXY', (rexposed, token)) else: msg = ('#RETURN', res) except AttributeError: if methodname is None: msg = ('#TRACEBACK', format_exc()) else: try: fallback_func = self.fallback_mapping[methodname] result = fallback_func( self, conn, ident, obj, *args, **kwds ) msg = ('#RETURN', result) except Exception: msg = ('#TRACEBACK', format_exc()) except EOFError: util.debug('got EOF -- exiting thread serving %r', threading.current_thread().name) sys.exit(0) except Exception:<------does not handle IOError,INTR here should retry recv() msg = ('#TRACEBACK', format_exc()) REF: http://bugs.python.org/issue17097
