[issue35676] class TestCase: docs are not correct
by אורי רודברג 25 Apr '21

25 Apr '21

New submission from אורי רודברג <uri(a)speedy.net>: I think some functions of `class TestCase` are not documented correctly in the docs. For example in https://docs.python.org/3.5/library/unittest.html and also https://docs.python.org/3.6/library/unittest.html and https://docs.python.org/3.7/library/unittest.html. Some of the functions which are not documented correctly: assertListEqual assertSetEqual assertDictEqual assertIsNone And many other functions. You can see some more details on https://github.com/python/typeshed/issues/2716. ---------- assignee: docs@python components: Documentation messages: 333137 nosy: docs@python, אורי רודברג priority: normal severity: normal status: open title: class TestCase: docs are not correct versions: Python 3.5, Python 3.6, Python 3.7 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue35676> _______________________________________

[issue16386] imp.find_module does not specify registry key it searches on windows
by Jan Duzinkiewicz 24 Apr '21

24 Apr '21

New submission from Jan Duzinkiewicz: quote from http://docs.python.org/3/library/imp.html#imp.find_module: "...on some systems some other places are looked in as well (on Windows, it looks in the registry which may point to a specific file)." I actually didn't know the registry key is listed in "using Python on Window" guide until I grepped for PythonCore (which kind of requires to know the key already) - so I'm submitting a patch that cross references find_module docs and using Python on Windows guide. ---------- assignee: docs@python components: Documentation files: import_nt_reg.patch keywords: patch messages: 174508 nosy: dhgmgn, docs@python priority: normal severity: normal status: open title: imp.find_module does not specify registry key it searches on windows versions: Python 2.7, Python 3.3 Added file: http://bugs.python.org/file27843/import_nt_reg.patch _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue16386> _______________________________________

[issue35114] ssl.RAND_status docs describe it as returning True/False; actually returns 1/0
by Josh Rosenberg 23 Apr '21

23 Apr '21

New submission from Josh Rosenberg <shadowranger+python(a)gmail.com>: The ssl.RAND_status online docs say (with code format on True/False): "Return True if the SSL pseudo-random number generator has been seeded with ‘enough’ randomness, and False otherwise." This is incorrect; the function actually returns 1 or 0 (and the docstring agrees). Fix can be one of: 1. Update docs to be less specific about the return type (use true/false, not True/False) 2. Update docs to match docstring (which specifically says 1/0, not True/False) 3. Update implementation and docstring to actually return True/False (replacing PyLong_FromLong with PyBool_FromLong and changing docstring to use True/False to match online docs) #3 involves a small amount of code churn, but it also means we're not needlessly replicating a C API's use of int return values when the function is logically bool (there is no error status for the C API AFAICT, so it's not like returning int gains us anything on flexibility). bool would be mathematically equivalent to the original 1/0 return value in the rare cases someone uses it mathematically. ---------- assignee: docs@python components: Documentation, SSL messages: 328917 nosy: docs@python, josh.r priority: low severity: normal status: open title: ssl.RAND_status docs describe it as returning True/False; actually returns 1/0 type: behavior _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue35114> _______________________________________

[issue32133] documentation: numbers module nitpick
by abcdef 23 Apr '21

23 Apr '21

New submission from abcdef <x(a)mailinator.com>: Documentation of the numbers module: https://docs.python.org/3/library/numbers.html states "None of the types defined in this module can be instantiated." This is true for Complex, Real, Rational, Integral but not for Number: >>> numbers.Number() <numbers.Number object at 0x7fcccc71f3c0> >>> numbers.Real() Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: Can't instantiate abstract class Real... Since Number doesn't have any abstract methods, the correct fix seems to be changing the documentation. I would try to convey something like this: "The types defined in this module can be used for subclassing and checking whether a specific class is in the numeric hierarchy; they are not used directly for instantiation. For this, you can use types such as `complex` or `fractions.Fraction`". ---------- assignee: docs@python components: Documentation messages: 306970 nosy: abcdef, docs@python priority: normal severity: normal status: open title: documentation: numbers module nitpick type: enhancement versions: Python 2.7, Python 3.6 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue32133> _______________________________________

[issue21352] improve indexing
by bob gailer 23 Apr '21

23 Apr '21

New submission from bob gailer: Inconsistencies / confusion with documentation Index Tab. Example (line numbers added for comments that follow): 1 max 2 built-in function 3 max (datetime.date attribute) 4 (datetime.datetime attribute) 5 (datetime.time attribute) 6 max() built-in function 7 (decimal.Context method) 8 (decimal.Decimal method) 9 (in module audioloop) The following all lead to confusion and frustration: Having 3 rows (1, 3, 6)that begin with max. Having an entry (1) that does nothing when double-clicked. double-clicking (2) takes us to a reference rather than a definition. RECOMMENDATION: change to: max() built-in function (sequence operation) (decimal.Context method) (decimal.Decimal method) max (datetime.date attribute) (datetime.datetime attribute) (datetime.time attribute) where double-clicking the first line goes to the max() definition in 2. Built-in Functions These comments apply, with a number of variations, to most built-in functions index entries. ---------- assignee: docs@python components: Documentation messages: 217170 nosy: bgailer, docs@python priority: normal severity: normal status: open title: improve indexing type: enhancement versions: 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/issue21352> _______________________________________

[issue19023] ctypes docs: Unimplemented and undocumented features
by Sye van der Veen 20 Apr '21

20 Apr '21

New submission from Sye van der Veen: In the ctypes documentation, there's mention of a BigEndianUnion/LittleEndianUnion that isn't actually implemented, and the "Arrays and pointers" section just reads "Not yet written". The attached patch adds the (Big|Little)EndianUnion classes (with tests), finishes the Array/_Pointer class docs (and adds missing cases to the tests), and makes some stylistic improvements to docs. The patch was made against default, but it's quite likely it could be back-ported all the way to Python 3.1. ---------- assignee: docs@python components: Documentation, Tests, ctypes hgrepos: 209 messages: 197764 nosy: docs@python, syeberman priority: normal severity: normal status: open title: ctypes docs: Unimplemented and undocumented features type: enhancement _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue19023> _______________________________________

[issue36868] New behavior of OpenSSL hostname verification not exposed, incorrectly documented
by Josh Rosenberg 17 Apr '21

17 Apr '21

New submission from Josh Rosenberg <shadowranger+python(a)gmail.com>: The What's New in 3.7 docs mention the change from #31399 to use OpenSSL's built-in hostname verification ( https://docs.python.org/3/whatsnew/3.7.html#ssl ), but aside from that, information about the change is largely undiscoverable and/or wrong. Specific problems: 1. The What's New docs repeatedly mention SSLContext.host_flags as the means of modifying behavior. The actual property is underscore prefixed though, as SSLContext._host_flags. Since SSLContext supports the creation of arbitrary names via __dict__, assigning to context.host_flags silently "works", it just fails to *do* anything (nothing ever reads it). 2. None of the flags are documented anywhere; the only way to discover them is to import _ssl (they're not exposed on ssl itself, just the internal C extension), then scan through the exposed names (they're all prefixed with HOSTFLAG_ AFAICT) 3. All of the flags are raw numeric values, but it seems like they should be IntEnums, like the other flags exposed by SSL (among other things, it would make it much easier to interpret the default _host_flags (currently it's just 4, when it could display as <HostFlags.HOSTFLAG_NO_PARTIAL_WILDCARDS: 4>) 4. Nothing about this change, _host_flags/host_flags, or the values of the flags themselves is mentioned on the ssl docs at all. 5. This unintentionally made a behavioral change (one that bit me, and may bite other folks using docker swarm, NETBIOS hostnames, etc.). Python's match_hostname implementation was fine with host names containing underscores (e.g. if the cert was wildcarded to *.example.com, it would match a_b_c.example.com just fine); they're not technically legal by the strict reading of the specs for host names (they're apparently legal for domain names, but not host names, which differ in ways I don't fully understand), but stuff like docker swarm names their services that way automatically, most (all?) browsers support visiting them, etc. It looks like OpenSSL (at least the 1.1.0g my Python 3.7.2 was built against) treats underscores as unmatchable, so any attempt to connect to such a host name in Python 3.7.2 dies with a SSLCertVerificationError, claiming a "Hostname mismatch, certificate is not valid for 'name_with_underscores.example.com'." I discovered all this because 3.7 broke some scripts I use to connect to docker swarm services. Before I realized the issue was underscores, I was trying to figure out how to tweak the host name checks (assuming maybe something was broken with wildcard matching), and stumbled across all the other issues with the docs, the lack of flag definition exposure, etc. For the record, I think it's reasonable to require legal host names (it was easy enough to fix for my case; I just updated our docker DNS server to provide aliases using only hyphens and changed the script to use the alias host names), but it would be nice if it was explicitly documented, and ideally, that Python itself recognize that underscores won't work and explicitly raise an exception saying why, rather than letting OpenSSL perform the rejection with a (to someone who doesn't know about the underscore issue) confusing error message. ---------- assignee: docs@python components: Documentation, Extension Modules, Library (Lib), SSL keywords: 3.6regression messages: 341990 nosy: christian.heimes, docs@python, josh.r, vstinner priority: normal severity: normal status: open title: New behavior of OpenSSL hostname verification not exposed, incorrectly documented type: behavior versions: Python 3.7, Python 3.8 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue36868> _______________________________________
