[issue11230] "Full unicode import system" not in 3.2

by John

New submission from John <jh45dev(a)gmail.com>: A few months ago I read that in 3.2 it will be possible to import modules that are located on paths containing any unicode character. (more precisely, with chars not in the local code page) After an hour or two trying to get this to work in 3.2rc3, I went looking for clues, and found these 2 messages in which Victor Stinner says this feature is delayed until Python 3.3: http://bugs.python.org/issue3080#msg126514 http://bugs.python.org/issue10828#msg125787 Could you please make it clear in documentation and web pages, that this feature is not working yet. The Python 3.2 download page includes this: "countless fixes regarding bytes/string issues; among them full support for a bytes environment (filenames, environment variables)" and I guessed this must cover importing from any unicode path, as there was no mention that such importing had been abandoned for this version. -- jh ---------- assignee: docs@python components: Documentation messages: 128711 nosy: docs@python, jh45 priority: normal severity: normal status: open title: "Full unicode import system" not in 3.2 versions: Python 3.2 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11230> _______________________________________

[issue10438] list an example for calling static methods from WITHIN classes

by Ian

New submission from Ian <ifreecarve(a)gmail.com>: Concerning this section of the docs: http://docs.python.org/library/functions.html#staticmethod There is no example for calling a static method from another static method within the same class. As I discovered later, it's simple: C.f() -- from inside the class or outside it. A total newbie will accept this and move on... but in other programming languages, it's frowned upon to the class name from within the class. For example, in PHP you use the "self::" prefix and Java you don't need a prefix at all. So, even though I had it right the first time, it didn't SEEM right... so I went on a wild goose chase, for nothing. Googling "java call static method" will get you java documentation that lists both cases, as does "c++ call static method" and "php call static method". I feel that by adding "Note: you must also use the C.f() syntax when calling from within the class", the documentation will be more complete. ---------- assignee: docs@python components: Documentation messages: 121314 nosy: docs@python, ifreecarve priority: normal severity: normal status: open title: list an example for calling static methods from WITHIN classes type: feature request _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue10438> _______________________________________

[issue11681] -b option undocumented

by Éric Araujo

New submission from Éric Araujo <merwok(a)netwok.org>: Python 2 has a -b command-line option which is undocumented. It is used by the warnings machinery to decide to warn about (-b) or raise an error (-bb) if someone uses str(bytes) or str(buffer) (explanation courtesy of grep and Python/pythonrun.c). ---------- assignee: docs@python components: Documentation keywords: easy messages: 132195 nosy: docs@python, eric.araujo priority: normal severity: normal stage: needs patch status: open title: -b option undocumented versions: Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11681> _______________________________________

[issue11726] linecache becomes specific to Python scripts in Python 3

by STINNER Victor

New submission from STINNER Victor <victor.stinner(a)haypocalc.com>: linecache document doesn't tell that the module reads the #coding:xxx cookie to get the encoding of the Python file. linecache reads this cookie since 41665 (May 09 2007). "The linecache module allows one to get any line from any file, ..." => "any file"! And the example uses /etc/passwd which is not a Python file. Not only it reads the #coding:xxx cookie, but updatecache() tries also a PEP 302 loader to read the file. linecache should be marked as very specific to Python scripts, or it should be patched to become more generic (don't read the cookie / use loader by default). Note: the locale encoding may change between to calls to the linecache module. ---------- assignee: docs@python components: Documentation, Library (Lib) messages: 132641 nosy: docs@python, haypo priority: normal severity: normal status: open title: linecache becomes specific to Python scripts in Python 3 versions: Python 3.1, Python 3.2, Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11726> _______________________________________

[issue11670] configparser read_file now iterates over f, docs still say it calls readline

by Larry Hastings

New submission from Larry Hastings <larry(a)hastings.org>: The documentation for configparser.RawConfigParser.read_file() states: "Read and parse configuration data from the file or file-like object in f (only the readline() method is used)." This was true in Python 3.1 and before. However in 3.2 the implementation of read_file changed. It no longer calls readline(). Instead, it iterates over the file object. Whoever made this change neglected to * fix the docs, or apparently * tell anybody. I've got the commit bit, so I'd be happy to fix this. I'd like to add it to the What's New In Python 3.2 as well; there's a section about configparser changes that would be perfect. Is it permissible to change the What's New document ex post facto like this? (Adding rhettinger so he can answer this.) ---------- assignee: docs@python components: Documentation messages: 132075 nosy: docs@python, larry, rhettinger priority: low severity: normal stage: needs patch status: open title: configparser read_file now iterates over f, docs still say it calls readline type: behavior versions: Python 3.2 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11670> _______________________________________

[issue10415] readline.insert_text documentation incomplete

by Justin Lebar

New submission from Justin Lebar <justin.lebar(a)gmail.com>: The readline documentation currently says: > readline.insert_text(string) > Insert text into the command line. But as far as I can tell, readline.insert_text() does something only when called from startup_hook or pre_input_hook. Here's an example of someone using the module in a way that works: http://swapoff.org/svn/cly/tags/0.7/cly/interactive.py ---------- assignee: docs@python components: Documentation messages: 121178 nosy: Justin.Lebar, docs@python priority: normal severity: normal status: open title: readline.insert_text documentation incomplete versions: Python 3.1 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue10415> _______________________________________

[issue9911] doc copyedits

by DSM

New submission from DSM <dsm001(a)users.sourceforge.net>: Various typo fixes for the docs. As usual, I left historical documents alone (except for 3.1 whatsnew: fixed the spelling of Jack Diederich's name). Fixing ~30 means I probably introduced ~3 problems of my own, but that should still be a net win..

[issue11643] Use |version| instead of X.Y in the doc

by Éric Araujo
