[issue17387] Error in C API documentation of PySequenceMethods
by Alex Orange May 31, 2020

May 31, 2020

New submission from Alex Orange: The documentation at http://docs.python.org/2/c-api/typeobj.html#PySequenceMethods is missing sq_slice between sq_item and sq_ass_item. This will mess up anyone trying to use anything after sq_item (that isn't using designated initializers). ---------- assignee: docs@python components: Documentation messages: 183779 nosy: Alex.Orange, docs@python priority: normal severity: normal status: open title: Error in C API documentation of PySequenceMethods versions: … [View More]

[issue15952] format(value) and value.__format__() behave differently with unicode format
by Chris Jerdonek May 31, 2020

May 31, 2020

New submission from Chris Jerdonek: format(value) and value.__format__() behave differently even though the documentation says otherwise: "Note: format(value, format_spec) merely calls value.__format__(format_spec)." (from http://docs.python.org/library/functions.html?#format ) The difference happens when the format string is unicode. For example: >>> format(10, u'n') u'10' >>> (10).__format__(u'n') # parentheses needed to prevent SyntaxError '10' So either the … [View More]

[issue11425] Cleanup sample codes in tutorial.
by INADA Naoki May 14, 2020

May 14, 2020

New submission from INADA Naoki <songofacandy(a)gmail.com>: * Insert spaces around operators and after commas. * Split one liner blocks (ex. def foo(x, y): return x + y) to multi-line blocks. * Insert empty line after def block for scripts (not interactive mode). * Use new-style raise (s/ralse KeyboardInterrupt/raise KeyboardInterrupt()/) * Use x ** 3 instead of x * x * x. Attached patch is for Python 2.6. I'll make same changes for Python 3.1 if this patch is accepted. ---------- … [View More]

[issue8940] *HTTPServer need a summary page with API inheritance table
by anatoly techtonik April 27, 2020

April 27, 2020

New submission from anatoly techtonik <techtonik(a)gmail.com>: The abundance of methods and hierarchy depth of various servers from "Internet Protocols and Support" section makes it extremely hard to navigate information. You need a strong OOP background to be able to use this doc effectively, as examples are not intuitive otherwise. Usually you need a decent IDE (such as Eclipse) to get a picture of class hierarchy and a table of all available methods with a mark where they were … [View More]

[issue14418] Document differences in SocketServer between Python 2.6 and 2.7
by Geoffrey Bache April 27, 2020

April 27, 2020

New submission from Geoffrey Bache <gjb1002(a)users.sourceforge.net>: Here I'm referring to the section about RequestHandler objects under the SocketServer page. http://docs.python.org/release/2.7.2/library/socketserver.html#requesthandl… This appears to be the same in Python 2.6 and Python 2.7. But the objects don't behave the same, in two respects: 1) For finish() "If setup() or handle() raise an exception, this function will not be called." This is true in Python 2.6. It appears … [View More]to no longer be true in Python 2.7, where finish() is called in a "finally" clause. 2) For handle(). "The default implementation does nothing". This is true up to a point, but using the default implementation has different effects. Specifically, if I try to read from a socket when the server has not written anything, I get an exception in Python 2.6 and an empty string in Python 2.7. Consider this code: ## server.py from SocketServer import TCPServer, StreamRequestHandler import sys, socket server = TCPServer((socket.gethostname(), 0), StreamRequestHandler) host, port = server.socket.getsockname() address = host + ":" + str(port) print "Started server at", address sys.stdout.flush() server.serve_forever() ## client.py import sys, socket servAddr = sys.argv[1] host, port = servAddr.split(":") serverAddress = (host, int(port)) sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.connect(serverAddress) sock.sendall("Some Message") sock.shutdown(1) response = sock.makefile().read() print "Got reply:", response sock.close() and compare the following: $ python2.7 server.py & Started server at 127.0.1.1:42759 $ python2.7 client.py 127.0.1.1:42759 Got reply: $ python2.6 server.py & Started server at 127.0.1.1:42758 $ python client.py 127.0.1.1:42758 Traceback (most recent call last): File "client.py", line 12, in <module> response = sock.makefile().read() File "/usr/lib/python2.7/socket.py", line 351, in read data = self._sock.recv(rbufsize) socket.error: [Errno 104] Connection reset by peer (doesn't matter which Python runs the client in the last case) I am unsure whether this is a bug in Python 2.6, or really what the reasoning behind the behaviour difference is, but I think this change in behaviour is worth a small note in the documentation (how it will behave if you try to read when nothing has been written) ---------- assignee: docs@python components: Documentation messages: 156869 nosy: docs@python, gjb1002 priority: normal severity: normal status: open title: Document differences in SocketServer between Python 2.6 and 2.7 versions: Python 2.6, Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue14418> _______________________________________ [View Less]

[issue14759] Berkeley DB License conditions are onerous (and poorly documented)

New submission from Jeff Laing <jefflaing(a)gmail.com>: As part of an audit of license compliance, I was looking at the terms in the LICENSE.txt that describe the Berkeley DB product.

[issue17422] language reference should specify restrictions on class namespace
by Eric Snow March 10, 2020

March 10, 2020

New submission from Eric Snow: (related to PEP 422 and issue #17044) The execution namespace from a class definition is passed as the third argument to the metaclass (see builtin___build_class__() in Python/bltinmodule.c). When applicable, which is almost always, the subsequent call to type.__new__() copies that namespace into a new dict which is in turn exposed via the class's __dict__. This matters in the case where a metaclass with __prepare__() gets used (or the PEP 422 equivalent). … [View More]
