[issue10048] urllib.request documentation confusing
by Antoine Pitrou April 26, 2019

April 26, 2019

New submission from Antoine Pitrou <pitrou(a)free.fr>: The urllib.request documentation intermingles old 2.x urllib (FancyURLopener, etc.) with urllib2-inherited (*Handler, build_opener, etc.) primitives without making any distinction. This makes it rather confusing for the reader to figure out which ones to use. Ideally, the use of the old primitives should also be discouraged. ---------- assignee: docs@python components: Documentation messages: 118179 nosy: docs@python, orsenthil, pitrou priority: normal severity: normal stage: needs patch status: open title: urllib.request documentation confusing versions: Python 3.1, Python 3.2 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue10048> _______________________________________

[issue11352] Buf in cgi module doc
by Pierre Quentel Feb. 24, 2019

Feb. 24, 2019

New submission from Pierre Quentel <pierre.quentel(a)gmail.com>: Hi, I wrote a patch for the cgi module in version 3.2rc1 (#4953). Small changes should be done to the documentation of this module to reflect the changes in the module API : - in section "20.2.2. Using the cgi module" original text : "If a field represents an uploaded file, accessing the value via the value attribute or the getvalue() method reads the entire file in memory as a string. This may not be what you want. You can test for an uploaded file by testing either the filename attribute or the file attribute. You can then read the data at leisure from the file attribute:" proposed new text (for files, value is bytes, not string, and the read() method on file also returns bytes) : "If a field represents an uploaded file, accessing the value via the value attribute or the getvalue() method reads the entire file in memory as bytes. This may not be what you want. You can test for an uploaded file by testing either the filename attribute or the file attribute. You can then read the data at leisure from the file attribute (the read() and readline() methods will return bytes) :" - version 3.2 introduced a parameter "encoding" for the FieldStorage constructor, used to decode the bytes received on the HTTP connection for fields other than files. This encoding must the one defined in the HTML document holding the form submitted to the CGI script ; it is usually defined by a meta tag : <meta http-equiv="Content-type" content="text/html;charset=latin-1"> or by the Content-Type header for this document I'm not sure where this should be mentioned in the module documentation. Maybe in "20.2.9. Common problems and solutions" for the moment. But there are plans (#11066) to introduce another interface to change the encoding of sys.stdout in the CGI script itself, so another option would be to open a specific section about encodings Hope it's clear enough Pierre ---------- assignee: docs@python components: Documentation messages: 129691 nosy: docs@python, quentel priority: normal severity: normal status: open title: Buf in cgi module doc type: behavior versions: Python 3.2 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11352> _______________________________________

[issue9842] Document ... used in recursive repr of containers

New submission from Éric Araujo <merwok(a)netwok.org>: Built-in containers like dict use an ellipsis to represent a recursive item. In the symbols index, “...” only links to the secondary prompt; I think it should also link to a paragraph explaining the display of recursive containers. ---------- assignee: docs@python components: Documentation keywords: easy messages: 116256 nosy: docs@python, eric.araujo priority: normal severity: normal stage: needs patch status: open title: Document ... used in recursive repr of containers versions: Python 2.7, Python 3.1, Python 3.2 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue9842> _______________________________________

[issue11233] clarifying Availability: Unix
by Sandro Tosi Oct. 15, 2018

Oct. 15, 2018

New submission from Sandro Tosi <sandro.tosi(a)gmail.com>: Hi, following up http://mail.python.org/pipermail/docs/2011-February/003083.html we have a chat on #python-dev on the topic, the situation is - all started with os.lchmod() and as.lchflags() methods not available on a Debian system - that's because POSIX does not require those functions and then Linux systems don't provide them - so we then thought about clarifying, only for those 2 methods, that they might not be available with a format like "availability: some unix systems" - then we noticed that on top of os doc there's a notice "An “Availability: Unix” note means that this function is commonly found on Unix systems. It does not make any claims about its existence on a specific operating system." and so we thought about linking every 'Availability: Unix' to that note - or transform that not in a footnote and link every 'Availability: Unix' for functions that might not be present to that footnote. It's enough for the conversation dump: ideas/suggestions? :) ---------- assignee: docs@python components: Documentation messages: 128746 nosy: docs@python, sandro.tosi priority: normal severity: normal status: open title: clarifying Availability: Unix _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11233> _______________________________________

[issue11015] Bring test.support docs up to date
by Nick Coghlan Feb. 11, 2018

Feb. 11, 2018

New submission from Nick Coghlan <ncoghlan(a)gmail.com>: The test.support docs are there to help CPython devs with writing good unit tests more easily. There are a few additions we've made in recent years that haven't made it into the .rst file, so it is easy to miss useful tools if you don't go looking through the module source code. There are some other helper modules (such as test.script_helper) that could also stand to be made easier to find. Fixing this is just a matter of doing a pass through test.support and the test directory looking for things that might be worth mentioning in the test package docs. ---------- assignee: docs@python keywords: easy messages: 127086 nosy: docs@python, ncoghlan priority: normal severity: normal stage: needs patch status: open title: Bring test.support docs up to date type: behavior _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11015> _______________________________________

[issue8722] Documentation for __getattr__
by Paul Davis Feb. 5, 2018

Feb. 5, 2018

New submission from Paul Davis <paul.joseph.davis(a)gmail.com>: The docs for __getattr__ in the object model section could be more specific on the behavior when a @property raises an AttributeError and there is a custom __getattr__ defined. Specifically, it wasn't exactly clear that __getattr__ would be invoked after a @property was found and evaluated. The attached script demonstrates the issue on OS X 10.6, Python 2.6.1 I'm thinking something along the lines of: If the attribute search encounters an AttributeError (perhaps due to a @property raising the error) the search is considered a failure and __getattr__ is invoked. ---------- assignee: docs@python components: Documentation files: example.py messages: 105790 nosy: Paul.Davis, docs@python priority: normal severity: normal status: open title: Documentation for __getattr__ type: feature request versions: Python 2.6 Added file: http://bugs.python.org/file17349/example.py _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue8722> _______________________________________

New submission from Alan Isaac <alan.isaac(a)gmail.com>: In PEP 227 missing text is marked with XXX. Most of this is just calls for examples and elaboration. However under the Implementation section XXX marks a substantive question about the documentation.

[issue11260] smtpd-as-a-script feature should be documented and should use argparse
by Xavier Morel Jan. 10, 2018

Jan. 10, 2018

New submission from Xavier Morel <xavier.morel(a)masklinn.net>: argparse has been merged to the standard library in 3.2, and (tell me if I'm wrong) would therefore be the "best-practices" way to parse command-line arguments. Numerous stdlib modules can be used as scripts, but they tend to have ad-hoc documentation (if they are at all documented) and arguments parsing (using any of the 4 available methods in Python: straight from sys.argv, getopt, optparse and argparse). I picked smtpd as a first shot since it does something useful (SMTP proxy) and has a pretty good (if ad-hoc) command-line documentation. smtpd is currently using getopt for its options parsing and the argument parsing is very cleanly factored: the port only had to replace the implementation of the `parseargs` function (and add and remove some helpers). * The port keeps the existing arguments semantics (including the mandatory host:port syntax for the local and remote specs if overridden) * The port tries to maintain the old error messages, but due to the way argparse works (or the way I used it for the specs) the parity is not perfect when providing incorrect specs * The CLI help uses argparse's formatting, and the documentation for the local and remote specs was set on these arguments rather than as an epilog. The version string was also removed from the help screen * Because they are set by argparse's arguments validation, the status codes on incorrect arguments are slightly different: - running smtpd.py as a regular user without the `--nosetuid` flag still exits with status 1 - providing incorrect spec formats (missing or non-int port) or providing too many positional arguments (3 or more) now exits with status 2 (formerly 1) ---------- assignee: docs@python components: Documentation, Library (Lib) files: smtpd-to-argparse.diff keywords: patch messages: 128917 nosy: barry, docs@python, xmorel priority: normal severity: normal status: open title: smtpd-as-a-script feature should be documented and should use argparse versions: Python 3.3 Added file: http://bugs.python.org/file20812/smtpd-to-argparse.diff _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11260> _______________________________________

[issue11253] autodocument first appearance of ctypes.wintypes constants
by anatoly techtonik Nov. 8, 2017

Nov. 8, 2017

New submission from anatoly techtonik <techtonik(a)gmail.com>: I've just noticed that my application is incompatible with Python 2.5, because ctypes.wintypes is missing SHORT constants. However, I can't find the information when these symbols were introduced first. To prevent such confusion in future it would be nice to extract symbol information for each Python release and automatically include the version of the first appearance in documentation. ---------- assignee: docs@python components: Documentation messages: 128893 nosy: docs@python, techtonik priority: normal severity: normal status: open title: autodocument first appearance of ctypes.wintypes constants versions: Python 2.5, Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11253> _______________________________________

[issue11230] "Full unicode import system" not in 3.2
by John July 19, 2017

July 19, 2017

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> _______________________________________
