[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). The language reference[1] should note that the object returned by __prepare__() is copied into a new dict when the class is finally created via the metaclass.

[issue13077] Unclear behavior of daemon threads on main thread exit
by etuardu March 9, 2020

March 9, 2020

New submission from etuardu <edonan(a)gmail.com>: The definition of daemon thread in the current documentation reads: «A thread can be flagged as a "daemon thread". The significance of this flag is that the entire Python program exits when only daemon threads are left. [...]» (http://docs.python.org/library/threading.html#thread-objects) I think it's not very clear from this that daemon threads themselves terminate when the program (main thread plus other non-daemon threads) terminates. I think this have to be said more explicitly. I'd propose a change with something like: «A thread can be flagged as a "daemon thread", which means it will get shut down when the overall program terminates. The entire Python program exits when only daemon threads are left.» ---------- assignee: docs@python components: Documentation messages: 144691 nosy: docs@python, etuardu priority: normal severity: normal status: open title: Unclear behavior of daemon threads on main thread exit type: behavior versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue13077> _______________________________________

[issue8824] Improve documentation of exec
by Terry J. Reedy Feb. 28, 2020

Feb. 28, 2020

New submission from Terry J. Reedy <tjreedy(a)udel.edu>: This doc improvement suggestion is inspired by #991196 (and subsequent duplicates) and the current discussion on py-dev in the thread 'variable name resolution in exec is incorrect' (which is not a correct claim). I believe there is consensus that the doc for exec needs improving. My suggestion (which others may amend) is that the following paragraph (from the 3.x builtin functions exec entry) "In all cases, if the optional parts are omitted, the code is executed in the current scope. If only globals is provided, it must be a dictionary, which will be used for both the global and the local variables. If globals and locals are given, they are used for the global and local variables, respectively. If provided, locals can be any mapping object." have these two sentences added: "If only globals is provided or if onedict is provided as both globals and locals, the code is executed in a new top-level scope. If different objects are given as globals and locals, the code is executed as if it were in a class statement in a new top-level scope." ---------- assignee: docs@python components: Documentation messages: 106552 nosy: docs@python, tjreedy priority: normal severity: normal status: open title: Improve documentation of exec versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue8824> _______________________________________

[issue15474] Differentiate decorator and decorator factory in docs
by Éric Araujo Feb. 27, 2020

Feb. 27, 2020

New submission from Éric Araujo <merwok(a)netwok.org>: Some of the confusion encountered when writing decorators arise from the difference between a decorator (@something) and a decorator factory (@something(args)). It would help to adopt this clearer terminology in our docs: a decorator takes the decorated function as argument and does its business, a decorator factory takes some arguments and returns a decorator which wraps the decorated function. (I think it was Nick who suggested this in a recent-ish mailing list thread.) ---------- assignee: docs@python components: Documentation messages: 166600 nosy: docs@python, eric.araujo, ncoghlan priority: normal severity: normal status: open title: Differentiate decorator and decorator factory in docs versions: Python 2.7, Python 3.2, Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue15474> _______________________________________

[issue23164] "pydoc filter" documentation restrictive
by Eric O. LEBIGOT Feb. 26, 2020

Feb. 26, 2020

New submission from Eric O. LEBIGOT: The pydoc documentation for filter reads: filter(function or None, sequence) -> list, tuple, or string Return those items of sequence for which function(item) is true. If function is None, return the items that are true. If sequence is a tuple or string, return the same type, else return a list. It would be nicer to know (e.g. when offline and with no local access to the HTML documentation) that filter() can actually be used more generally with an iterable: filter(function or None, **iterable**) -> list, tuple, or string Return those items of **iterable** for which… ---------- assignee: docs@python components: Documentation messages: 233416 nosy: docs@python, lebigot priority: normal severity: normal status: open title: "pydoc filter" documentation restrictive type: enhancement versions: Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue23164> _______________________________________
