[issue21596] asyncio.wait fails when futures list is empty
by Sebastian Kreft 04 May '20

04 May '20

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> _______________________________________

[issue33649] asyncio docs overhaul
by Yury Selivanov 04 May '20

04 May '20

New submission from Yury Selivanov <yselivanov(a)gmail.com>: An overhaul of asyncio documentation is long overdue. Here's the structure for it that I have in mind: - Introduction (what is asyncio and async/await) - A quick tutorial (show how to use asyncio.run() and basic functions like asyncio.sleep() and teach that asyncio programs are all about async/await and *not* about callbacks or event loops) - High-level APIs (Tasks, Streams, Subprocesses, few other functions) - Low-level APIs - Preface (talk a bit about everything: what's an event loop, what is a Future and a Transport) - Futures - Event loop APIs - Transports and Protocols (when to use and when not to use them) - Tutorials - High-level networking server - HTTP application - Low-level protocol implementation using Transports - etc ---------- assignee: docs@python components: Documentation, asyncio messages: 317709 nosy: akuchling, asvetlov, docs@python, yselivanov priority: normal severity: normal status: open title: asyncio docs overhaul type: enhancement versions: Python 3.7, Python 3.8 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue33649> _______________________________________

[issue8940] *HTTPServer need a summary page with API inheritance table
by anatoly techtonik 27 Apr '20

27 Apr '20

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 27 Apr '20

27 Apr '20

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> _______________________________________

[issue26665] pip is not bootstrapped by default
by Axel Luttgens 27 Apr '20

27 Apr '20

New submission from Axel Luttgens: Relevant page: https://docs.python.org/2/library/ensurepip.html One may read: In most cases, end users of Python shouldn’t need to invoke this module directly (as pip should be bootstrapped by default), but it may be needed if installing pip was skipped when installing Python (or when creating a virtual environment) or after explicitly uninstalling pip. As far as I correctly read the configure file that comes with the 2.7.11 tarball, the default is to behave as if --with-ensurepip=no had been passed. As a result, that sentence fragment: (as pip should be bootstrapped by default) may appear somewhat ambiguous for those compiling Python themselves. Perhaps could this one avoid some head scratching: (as packagers are expected to have bootstrapped pip) HTH, Axel ---------- assignee: docs@python components: Documentation messages: 262610 nosy: Axel, docs@python priority: normal severity: normal status: open title: pip is not bootstrapped by default type: enhancement versions: Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue26665> _______________________________________

[issue30882] Built-in list disappeared from Python 2.7 intersphinx inventory
by Christoph Deil 27 Apr '20

27 Apr '20

New submission from Christoph Deil: We have a project where we sub-class `list`. Since recently our docs build is failing because the intersphinx inventory entry for `list` on Python 2.7 doesn't exist any more. I think this is a regression, because Python 2.7 is supposed to be stable and other functions and classes here are still there, just "list" is missing: https://docs.python.org/2.7/library/functions.html#func-list Just in case someone else sees this issue, the Sphinx warning looks like this: ``` docs/api/pyregion.ShapeList.rst:7: WARNING: py:class reference target not found: list ``` if you have something like ``` class ShapeList(list): """My list sub-class""" ``` ---------- assignee: docs@python components: Documentation messages: 297993 nosy: Christoph.Deil, docs@python priority: normal severity: normal status: open title: Built-in list disappeared from Python 2.7 intersphinx inventory versions: Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue30882> _______________________________________

[issue14759] Berkeley DB License conditions are onerous (and poorly documented)
by Jeff Laing 27 Apr '20

27 Apr '20

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> _______________________________________

[issue22863] https://docs.python.org/ should make a true 2.7.8 version available
by Marc-Andre Lemburg 27 Apr '20

27 Apr '20

New submission from Marc-Andre Lemburg: The documentation shown for Python 2.7.8 currently includes 2.7.9 parts, e.g. for the ssl modules (https://docs.python.org/2.7/library/ssl.html). Since there were so many changes to the ssl module for 2.7.9 which are not available in 2.7.8, I think it would be good to be able to not only select "2.7.8" from the doc version drop-down, but to also really get that particular version of the documentation, and provide a separate "2.7.9" snapshop as well. I tried https://docs.python.org/2.7.8/library/ssl.html, but that doesn't seem to exist. PS: I'm not sure whether this is the right tracker to report this. Feel free to move it elsewhere. ---------- assignee: docs@python components: Documentation messages: 231113 nosy: docs@python, lemburg priority: normal severity: normal status: open title: https://docs.python.org/ should make a true 2.7.8 version available versions: Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue22863> _______________________________________
