[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 documentation should be changed, or the behavior should be changed to match. Related to this: neither the "Format Specification Mini-Language" documentation nor the string.Formatter docs seem to say anything about the effect that a unicode format string should have on the return value (in particular, should it cause the return value to be unicode or not): http://docs.python.org/library/string.html#formatspec http://docs.python.org/library/string.html#string-formatting See also issue 15276 (int formatting), issue 15951 (empty format string), and issue 7300 (unicode arguments). ---------- assignee: docs@python components: Documentation messages: 170575 nosy: cjerdonek, docs@python priority: normal severity: normal status: open title: format(value) and value.__format__() behave differently with unicode format type: behavior versions: Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue15952> _______________________________________

May 17, 2020

New submission from anatoly techtonik: zipfile doesn't restore file attributes when extracting. Documentation should at least contain example how to do this manually, because the ony way to do this - through ZipInfo.external_attr is too cryptic. ---------- assignee: docs@python components: Documentation messages: 191447 nosy: docs@python, techtonik priority: normal severity: normal status: open title: ZipInfo.external_attr are not documented versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4, Python 3.5 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue18262> _______________________________________

[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. ---------- assignee: docs@python components: Documentation files: cleanup_tutorial_codes.patch keywords: patch messages: 130225 nosy: docs@python, naoki priority: normal severity: normal status: open title: Cleanup sample codes in tutorial. versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3 Added file: http://bugs.python.org/file21027/cleanup_tutorial_codes.patch _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11425> _______________________________________

[issue21596] asyncio.wait fails when futures list is empty
by Sebastian Kreft May 4, 2020

May 4, 2020

New submission from Sebastian Kreft: Passing an empty list/set of futures to asyncio.wait raises an Exception, which is a little annoying in some use cases. Probably this was the intended behavior as I see there's a test case for that. If such, then I would propose to document that behavior. ---------- assignee: docs@python components: Documentation messages: 219290 nosy: Sebastian.Kreft.Deezer, docs@python priority: normal severity: normal status: open title: asyncio.wait fails when futures list is empty versions: Python 3.4 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue21596> _______________________________________

[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 inherited from. Such table (at least Class Hierarchy view screenshot from Eclipse) should be available in reference for descendant classes. ---------- assignee: docs@python components: Documentation messages: 107321 nosy: docs@python, techtonik priority: normal severity: normal status: open title: *HTTPServer need a summary page with API inheritance table versions: Python 2.7, Python 3.1, Python 3.2 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue8940> _______________________________________

[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 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> _______________________________________

[issue14759] Berkeley DB License conditions are onerous (and poorly documented)
by Jeff Laing April 26, 2020

April 26, 2020

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. I had thought this would be under the standard Berkeley license, but Oracle have added their own zinger. * 3. Redistributions in any form must be accompanied by information on * how to obtain complete source code for the DB software and any * accompanying software that uses the DB software. The source code * must either be included in the distribution or be available for no * more than the cost of distribution plus a nominal fee, and must be * freely redistributable under reasonable conditions. So, my application, which embeds Python (rather than running it as python.exe) and includes the standard runtime library, must distribute my source code. This page: http://mail.python.org/pipermail/python-dev/2008-September/082316.html suggests that this is not the case for regular Python, but it makes no statement about "embedding". Sadly the Oracle page it links to suggesting this is not an issue, does not exist. The general "License" page on the Python websites makes no reference whatsoever to Berkeley DB license obligations. I note that there are other modules mentioned on the Licenses webpage that are not in the LICENSES.txt file, and vice versa. I have no idea whether this is deliberate, or an oversight. ---------- assignee: docs@python components: Documentation messages: 160238 nosy: Jeff.Laing, docs@python priority: normal severity: normal status: open title: Berkeley DB License conditions are onerous (and poorly documented) type: enhancement versions: Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue14759> _______________________________________

[issue17904] bytes should be listed as built-in function for 2.7

April 26, 2020

New submission from Florent Xicluna: Looking into the summary table, there's no information about the `bytes` built-in alias for `str`: http://docs.python.org/2/library/functions.html IMHO it should appear in this table (as str, unicode, bytearray) with the appropriate `.. versionadded:`. ---------- assignee: docs@python components: Documentation messages: 188349 nosy: docs@python, flox priority: normal severity: normal status: open title: bytes should be listed as built-in function for 2.7 type: behavior versions: Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue17904> _______________________________________

[issue21760] inspect documentation describes module type inaccurately
by Eric Snow April 11, 2020

April 11, 2020

New submission from Eric Snow: In the documentation for the inspect module, the module type is described with just 2 of its potential 7 attributes. The language reference[2] and importlib docs[3] both provide an accurate list of module attributes. Furthermore, the description for __file__ should be fixed. It should be clear that __file__ reflects the location from which the module was loaded, that location is not necessarily a filename, and the attribute may not exist if the module was not loaded from a specific location (e.g. builtin and frozen modules). The same goes for __cached__ [1] https://docs.python.org/dev/library/inspect.html#types-and-members [2] https://docs.python.org/3/reference/import.html#import-related-module-attri… [3] https://docs.python.org/3/library/importlib.html#importlib.machinery.Module… ---------- assignee: docs@python components: Documentation messages: 220576 nosy: docs@python, eric.snow priority: normal severity: normal stage: needs patch status: open title: inspect documentation describes module type inaccurately versions: Python 3.4, Python 3.5 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue21760> _______________________________________
