[issue24654] PEP 492 - example benchmark doesn't work (TypeError)
Yury Selivanov added the comment:
Fixed in https://hg.python.org/peps/rev/7ad183c1d9be
I'll quote the commit message here:
pep-492: Update benchmark code
Since coroutines now have a distinct type, they do not support
iteration. Instead of doing 'list(o)', we now do 'o.send(None)'
until StopIteration.
Note, that the updated timings are due to the difference of
doing a loop in Python vs doing it in C ('list()' vs 'while True').
Marcin and Terry, thanks for reporting this!

[issue24654] PEP 492 - example benchmark doesn't work (TypeError)
Stefan Behnel added the comment: Thanks for updating the micro-benchmark. Just FYI (and sorry for hijacking this ticket), I ran it through Cython. Here are the numbers: Cython 0.23 (latest master) binary(21) * 3: total 1.609s abinary(21) * 3: total 1.514s CPython 3.5 (latest branch) binary(21) * 3: total 4.653s abinary(21) * 3: total 4.750s The low factor between the two shows (IMO) that using a type slot function for await was a very good idea. Streamlining FetchStopIteration might bring another bit. I also tried the same thing with alternating recursively between the Python and Cython implementation by changing it to l = await cy_abinary(n - 1) r = await py_abinary(n - 1) binary(21) * 3: total 3.835s abinary(21) * 3: total 3.952s So even the slow fallback paths seem pretty efficient on both sides. -- nosy: +scoder ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24654 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue24659] dict() built-in fails on iterators with a keys attribute
Christian Barcenas added the comment:
Should have clarified that the specific issue that is outlined in #5945 is that
PyMapping_Check returns 1 on sequences (e.g. lists), which would mean something
like x = [('one', 1), ('two', 2)]; dict(x) would fail in 3.x because x would be
incorrectly evaluated as a mapping rather than as an iterable.

[issue24659] dict() built-in fails on iterators with a keys attribute
New submission from Christian Barcenas:
I noticed an inconsistency today between the dict() documentation vs.
implementation.
The documentation for the dict() built-in [1] states that the function accepts
an optional positional argument that is either a mapping object [2] or an
iterable object [3].
Consider the following:
import collections.abc
class MyIterable(object):
def __init__(self):
self._data = [('one', 1), ('two', 2)]
def __iter__(self):
return iter(self._data)
class MyIterableWithKeysMethod(MyIterable):
def keys(self):
return And now for something completely different
class MyIterableWithKeysAttribute(MyIterable):
keys = It's just a flesh wound!
assert issubclass(MyIterable, collections.abc.Iterable)
assert issubclass(MyIterableWithKeysMethod, collections.abc.Iterable)
assert issubclass(MyIterableWithKeysAttribute, collections.abc.Iterable)
assert not issubclass(MyIterable, collections.abc.Mapping)
assert not issubclass(MyIterableWithKeysMethod, collections.abc.Mapping)
assert not issubclass(MyIterableWithKeysAttribute, collections.abc.Mapping)
# OK
assert dict(MyIterable()) == {'one': 1, 'two': 2}
# Traceback (most recent call last):
# File stdin, line 1, in module
# TypeError: 'MyIterableWithKeysMethod' object is not subscriptable
assert dict(MyIterableWithKeysMethod()) == {'one': 1, 'two': 2}
# Traceback (most recent call last):
# File stdin, line 1, in module
# TypeError: attribute of type 'str' is not callable
assert dict(MyIterableWithKeysAttribute()) == {'one': 1, 'two': 2}
The last two assertions should not fail, and it appears that the offending code
can be found in Objects/dictobject.c's dict_update_common:
else if (arg != NULL) {
_Py_IDENTIFIER(keys);
if (_PyObject_HasAttrId(arg, PyId_keys))
result = PyDict_Merge(self, arg, 1);
else
result = PyDict_MergeFromSeq2(self, arg, 1);
}
PyDict_Merge is used to merge key-value pairs if the optional parameter is a
mapping, and PyDict_MergeFromSeq2 is used if the parameter is an iterable.
My immediate thought was to substitute the _PyObject_HasAttrId call with
PyMapping_Check which I believe would work in 2.7, but due to #5945 I don't
think this fix would work in 3.x.
Thoughts?

[issue24659] dict() built-in fails on iterators with a keys attribute
Martin Panter added the comment: It is at least an omission from the documentation. The glossary https://docs.python.org/dev/glossary.html#term-mapping refers to the Mapping ABC. From Christian’s point of view, the quack of an iterator with just a “keys” attribute sounds more like an iterator than a mapping. I think the documentation for the dict() constructor should say how to ensure the iterable and mapping modes are triggered. Perhaps dict.update() should also, because it appears to also treat non-dict() “mappings” differently to plain iterators. -- nosy: +vadmium ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24659 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Josh Rosenberg added the comment: Neither of those example should work (and neither do on my 3.4.0 installation). Heaps must have sortable components; you could only include callables (which are not sortable) in the tuples being sorted if you guarantee that some element(s) before the callable will ensure the elements are ordered without falling back on comparing the callable members. This isn't a bug; heapq.heapify() *should* fail in this case, and in any case where sorted() would fail due to uncomparable objects. -- nosy: +josh.r ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24660 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

This is how function objects, lambda objects, bound class methods, etc, are meant to work. Python doesn’t implement ordering comparisons for them. This is kind of explained at https://docs.python.org/dev/reference/expressions.html#comparisons. See Issue 12067 if you want to help improve this section of the documentation. If you don’t care about the order, perhaps you could ensure the first item in each tuple is unique, or add a dummy item in the middle that ensures the tuples have a definite order: (0, 0, lambda x: 42) (0, 1, lambda x: 56) True -- nosy: +vadmium resolution: - not a bug status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24660 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10716] Modernize pydoc to use better HTML and separate CSS
Frédéric Jolliton added the comment: Oh god. The HTML produced by pydoc is awful. This is absolutely nothing modern about it. The code itself hurts my brain. It feels very old (14 years old..), and the HTML production is overly complex, and hard to check regarding correct quoting/escaping. Generating modern HTML5/CSS would mean: - Using h1, h2, for section title, - Forget about br (this element should never be used nowadays), - Forget about hr (let the CSS decide when to insert a visual separator after/before a given element), - Don't use code for block of code. This is an inline element. Use pre class=code for example. - Don't use table all over the place for formatting everything (use li for the list of modules for instance), - Drop these useless dd/dd (empty!) - No need to replace \n by br, or to replace space by nbsp;. The formatting can be achieved by white-space: pre in CSS. - a name=.. or a id=.. could be replaced by span id=.. class=.. to distinguish them from hyperlinks. - the table docclass could be a serie of h2 (or h3) title followed by the content of the section. The table seems useless because there are no particular requirement for an alignment. - and so on, and so on, .. Actually, I think this need a complete rewrite. This is a useful tool to have included with Python, but this need a serious refresh. To me, a modern documentation is something like this (from the Rust documentation): https://doc.rust-lang.org/std/option/enum.Option.html https://doc.rust-lang.org/std/option/index.html (Look at the generated HTML too.

Christian Barcenas added the comment: I'm aware of duck typing but I don't think this is the right place for it. (Although ABCs are ostensibly a kind of duck typing, as they do not require implementing classes to inherit from the ABC.) As Martin noticed, the glossary directly defines a mapping as a class that implements the Mapping ABC, and likewise the definition of an iterable under the glossary would satisfy the Iterable ABC. I think this is not just a documentation issue: the quack of a mapping has been well-defined and consistent since Python 2.7. Same for iterables. (It is worth noting that 2.6's definition of mapping was indeed just any object with a __getitem__ method https://docs.python.org/2.7/glossary.html#term-mapping) I think the documentation for the dict() constructor should say how to ensure the iterable and mapping modes are triggered.

[issue24666] Buffered I/O does not take file position into account when reading blocks
New submission from Eric Pruitt: When buffering data from a file, the buffered I/O does not take into account the current file descriptor position. In the following example, I open a file and seek forward 1,000 bytes: f = open(test-file, rb) f.seek(1000) 1000 f.readline() The filesystem on which test-file resides has a block size of 4,096 bytes, so on the backend, I would expect Python to read 3,096 bytes so the next read will be aligned with the filesystem blocks. What actually happens is that Python reads a 4,096 bytes. This is the output from an strace attached to the interpreter above: Process 16543 attached lseek(4, 0, SEEK_CUR) = 0 lseek(4, 1000, SEEK_SET)= 1000 read(4, \000\000\000\000\000\000\000\000\000\000..., 4096) = 4096 -- components: IO messages: 246931 nosy: ericpruitt priority: normal severity: normal status: open title: Buffered I/O does not take file position into account when reading blocks type: behavior versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24666 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue8450] httplib: false BadStatusLine() raised
Martin Panter added the comment:
Issue 3566 has added a new exception subclass, RemoteDisconnected, in 3.5.
People are still complaining about the old BadStatusLine exception in Python 2
though. See Issue 23054.
Python 2 could still get better documentation of the BadStatusLine exception.
Currently it gives the impression that it only happens when the “strict”
parameter is True, and a status line was received that was not understood.
The exception message could also be improved. Due to Issue 7427, there is a
special case to make the message literally two quote signs (''), representing
an empty string. Perhaps messages like “End of stream signalled”, “No status
line”, or “Empty status line” would be clearer.

[issue24659] dict() built-in fails on iterators with a keys attribute
Raymond Hettinger added the comment:
I'm aware of duck typing but I don't think this
is the right place for it.
The code for dicts is very old, stable, and unlikely to change. Also, the
logic of checking for .keys() is immortalized in the
collections.abc.MutableMapping update() method.
For the most part, consumers of iterables, sequences, and mappings are allowed
to use duct-typing (this is a feature of the language, not a bug).
The docs can be improved in a number of places. For example the docstring on
the dict constructor is out of sync with the dict.update() method:
print(dict.__doc__)
dict() - new empty dictionary
dict(mapping) - new dictionary initialized from a mapping object's
(key, value) pairs
dict(iterable) - new dictionary initialized as if via:
d = {}
for k, v in iterable:
d[k] = v
dict(**kwargs) - new dictionary initialized with the name=value pairs
in the keyword argument list. For example: dict(one=1, two=2)
print(dict.update.__doc__)
D.update([E, ]**F) - None. Update D from dict/iterable E and F.
If E is present and has a .keys() method, then does: for k in E: D[k] =
E[k]
If E is present and lacks a .keys() method, then does: for k, v in E: D[k]
= v
In either case, this is followed by: for k in F: D[k] = F[k]
In addition, the glossary entries for iterable, sequence, and mapping need to
be improved to distinguish between their somewhat vague use in a general sense
versus the specific meaning of isinstance(obj, Mapping). Unless the docs
specify a check for the latter, they almost always do some form of duck-typing
or a check for concrete built-in class or subclass.
Terms like mapping and sequence are often used somewhat generally both
inside and outside the Python world. Sometimes mapping is used in the
mathematic sense (pairing each member of the domain with each member of the
range), http://www.icoachmath.com/math_dictionary/mapping.html, and sometimes
in the sense of a subset of dict capabilities (i.e. has __getitem__ and keys).
The docs for PyMapping_Check() need to be updated to indicate the known
limitations of the check and to disambiguate it from isinstance(obj, Mapping).
