[issue45606] pathlib.Path.glob() does not list dangling symlink when pattern is the exact filenane

[Andrei Kulakov]

Andrei Kulakov  added the comment:

By the way note that path.glob('**/my_symlink') also does return the dangling 
symlink match. And glob.glob('my_symlink') also returns a dangling symlink.

[issue45606] pathlib.Path.glob() does not list dangling symlink when pattern is the exact filenane

[Andrei Kulakov]

Andrei Kulakov  added the comment:

The issue is that _PreciseSelector follows the symlink when it checks if a path 
exists before yielding it as a result.

I've put up a PR with a fix; I've also added a *follow_symlinks* arg to 
`exists()` method because it seems more logical to be able to test if a path 
exists via the same method rather than having to also remember and to check for 
it being a symlink.

I will add docs and news a bit later today or tomorrow.

[issue45852] statistics.mode test doesn't test what it claims to

[Stefan Pochmann]

New submission from Stefan Pochmann :

This test:

def test_counter_data(self):
# Test that a Counter is treated like any other iterable.
data = collections.Counter([1, 1, 1, 2])
# Since the keys of the counter are treated as data points, not the
# counts, this should return the first mode encountered, 1
self.assertEqual(self.func(data), 1)

If the mode() code *were* wrong this way (used Counter(data) instead of 
Counter(iter(data))), then the test wouldn't detect it, as mode() would still 
return 1. The test data should be [1, 2, 2, 2] instead, in which case such 
wrong mode() would return 2.

It used to be correct but wasn't adjusted correctly when mode() switched from 
raising an error for multiple modes to returning the first. The old code was:

def test_counter_data(self):
# Test that a Counter is treated like any other iterable.
data = collections.Counter([1, 1, 1, 2])
# Since the keys of the counter are treated as data points, not the
# counts, this should raise.
self.assertRaises(statistics.StatisticsError, self.func, data)

[issue45851] statistics.multimode is inefficient (time and space) (mode somewhat, too)

[Stefan Pochmann]

New submission from Stefan Pochmann :

The current implementation is:

def multimode(data):
counts = Counter(iter(data)).most_common()
maxcount, mode_items = next(groupby(counts, key=itemgetter(1)), (0, []))
return list(map(itemgetter(0), mode_items))

The most_common() does a complete sort of Counter item tuples, taking O(n log 
n) time and quite big O(n) extra space (mostly for all those tuples).

When Raymond Hettinger suggested it in 
https://bugs.python.org/issue35892#msg336338 he said it should have "running 
speed that is optimal for the desired result". But then he detailed that with 
"Slow O(n log n), loads all data in memory, full sort".

Which seems like a mistake, as that's not optimal. It's easy to do in O(n) time 
and O(1) extra memory (in addition to the Counter and result, I mean):

def multimode(data):
counts = Counter(iter(data))
if not counts:
return []
maxcount = max(counts.values())
return [value for value, count in counts.items() if count == maxcount]

If there are only very few *different* values then the time/space after 
creating the Counter is insignificant compared to the Counter creation. But if 
there are many different values, it can be significant.

statistics.mode takes O(n) time and O(1) space, which is optimal, but I found 
an apparently faster way anyway (code at end).

For example for data = random.choices(range(n), k=n):

   | multimode |   mode
 n | current  proposal | current  proposal
---+---+--
 1 |131%70%|125%   58%
10 |144%73%|119%   53%
   100 |126%71%|108%   29%
 1,000 |123%65%| 62%   22%
10,000 |172%55%| 53%   18%
   100,000 |164%44%| 55%   20%
 1,000,000 | 85%20%| 22%4%
10,000,000 | 56%12%| 11%4%

All four start with Counter(iter(data)), so I took that as baseline and the 
above results show relative additional times. For example 55% means if Counter 
construction alone took 10 seconds, the function took 15.5 seconds.

An extreme case, data = list(range(n)):

   | multimode|   mode
 n | current proposal | current proposal
---+--+-
 1 |   128%   67% |   124%   56%
10 |   187%   93% |   141%   52%
   100 |   316%  149% |   181%   45%
 1,000 |   380%  174% |   213%   46%
10,000 |   349%  111% |   146%   30%
   100,000 |   397%  128% |   159%   34%
 1,000,000 |   336%   95% |   112%   24%
10,000,000 |   349%   97% |   109%   23%

I also tried a bunch of other cases, didn't find one where my versions weren't 
quite a bit faster.

My mode() version:

from operator import indexOf
from itertools import islice

def mode(data):
counts = Counter(iter(data))
if not counts:
raise StatisticsError('no mode for empty data') from None
maxcount = max(counts.values())
index = indexOf(counts.values(), maxcount)
return next(islice(counts, index, None))

[issue45813] Importing asyncio after deleting a coroutine object and before cleaning it up leads to crashing on Python3.11

[Terry J. Reedy]

Terry J. Reedy  added the comment:

No crash on Windows running in CommandPrompt (using -i to ensure that python 
survives running the test code):

C:\Users\Terry>py -3.10 -i f:/dev/tem/tem.py
f:\dev\tem\tem.py:5: RuntimeWarning: coroutine 'f' was never awaited
  del f
RuntimeWarning: Enable tracemalloc to get the object allocation traceback
>>> quit()

C:\Users\Terry>py -3.11 -i f:/dev/tem/tem.py
f:\dev\tem\tem.py:5: RuntimeWarning: coroutine 'f' was never awaited
  del f
RuntimeWarning: Enable tracemalloc to get the object allocation traceback
>>> quit()

Running in IDLE, I only see the first warning.  (IDLE bug?  python behavior 
difference?  Don't know yet.)  On 3.11, the remote process crashes and IDLE's 
Shell does an unrequested restart.

Looks like the fix for those errors is to specify the arguments to the linker 
in PCbuild/pyproject.props

 /OPT:REF,NOICF 
/CGTHREADS:1 /PDBTHREADS:1 %(AdditionalOptions)

I don't particularly know what a good number of threads is for this. One seems 
safe, but maybe we can get faster builds with more?

[issue45506] Out of source tree builds failing on main - test_importlib others unreliable

[Steve Dower]

Steve Dower  added the comment:

Hijacking this issue number for a related test failure I found: if you "make 
install" Python and then run the test_embed tests from the build directory, 
some will successfully find the stdlib under PREFIX and fail because they 
expect to never find it.

PR incoming.

[issue45849] Embedded python doesn't recognize exit()

[Steve Dower]

Steve Dower  added the comment:

This is expected. The top-level exit() command only exists when the site module 
is imported, which is not the default for embedded Python (you should specify 
all the import paths explicitly, since they're going to be in your app rather 
than found by searching the disk).

You probably want to use sys.exit() in your script.

[issue44556] ctypes unittest crashes with libffi 3.4.2

[Eli Rykoff]

Eli Rykoff  added the comment:

To add a bit more color, I don't think you can explicitly set 
LIBFFI_INCLUDE_DIR, it's set by the configure script explicitly.  The problem 
is that some time between python 3.9 and 3.10 the configure script has (at 
least in our system) failed to figure out the $PKG_CONFIG variable correctly.  
It should be set to the executable with the full path name, as is done with 
3.9, but now it is set to just the executable name.  When that happens the 
library location check fails.

[issue44556] ctypes unittest crashes with libffi 3.4.2

[jakirkham]

jakirkham  added the comment:

We ran into the same issue in conda-forge ( 
https://github.com/conda-forge/python-feedstock/issues/522 ).

The problem is Apple also supplies their own `libffi`. However if the build 
scripts in CPython fail to find the user provided `libffi`, they end up pulling 
the headers from Apple's `libffi`, but the linker will link to the user 
provided `libffi`. IOW mashing these two incompatible `libffi`'s together. As 
result one gets crashes like the one illustrated in this bug.

In conda-forge, we are resolving this by forcing our `pkg-config` to be used to 
ensure we pick up the headers from our `libffi` as well as the libraries. Other 
users may be able to workaround this issue by explicitly setting 
`LIBFFI_INCLUDE_DIR`.

That said, it would be preferable to have a clear way to specify the `libffi` 
used and ensure that Apple's one doesn't get accidentally pulled in. If this 
exists and we are just missing these details, some pointers to this effect 
would be very helpful.

[issue45805] CO_FUTURE_ANNOTATIONS flag is not documented or in inspect

[Éric Araujo]

Éric Araujo  added the comment:

No worry about posting multiple messages.

I think the flag is documented through the __future__ module.
Future imports are both special-cased by the compiler to enable custom 
behaviour, but also real, regular imports!

>>> from __future__ import annotations
>>> annotations
_Feature((3, 7, 0, 'beta', 1), (3, 10, 0, 'alpha', 0), 16777216)
>>> hex(annotations.compiler_flag)
'0x100'

[issue45356] Calling `help` executes @classmethod @property decorated methods

[Alex Waygood]

Alex Waygood  added the comment:

It makes me sad that the stdlib will no longer provide a way to compose 
classmethods with other descriptors. However, I agree that deprecating 
classmethod  chaining is probably the correct course of action, given the 
complications this feature has caused, and the backwards-compatibility issues 
it raises.

This is probably a conversation for another BPO issue or the python-ideas 
mailing list, but I hope some consideration can be given in the future as to 
whether a new classmethod-like feature could possibly be added to functools 
that would enable this kind of decorator chaining without the same 
code-breakage concerns that this feature has had.

[issue45356] Calling `help` executes @classmethod @property decorated methods

[Raymond Hettinger]

Raymond Hettinger  added the comment:

I propose deprecating classmethod chaining.  It has become clear that it 
doesn't really do what people wanted and can't easily be made to work.

By even suggesting that some stateful decorators are composable, we've ventured 
onto thin ice.  Wrapping property in a classmethod doesn't produce something 
that behaves like a real property.  Mixing staticmethod and property doesn't 
work at all.  Putting abstractmethod in the mix doesn't work well either.  The 
ecosystem of code inspection tools, like help() in this issue, is wholly 
unprepared for recognizing and working around these combinations.  The latest 
"fix" for classmethod chaining looks weird and worriesome as well:  
self.f.__get__(cls, cls).

Classmethod chaining is relatively new, so we will affect very little code by 
deprecating it.  Any of the possible use cases can be served in other ways like 
the wrapt package or by explicit code in __getattribute__.

[issue45356] Calling `help` executes @classmethod @property decorated methods

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Also see:  https://bugs.python.org/issue42073

The classmethod pass through broke some existing code and the "fix" for it 
looks dubious:

if hasattr(type(self.f), '__get__'):
return self.f.__get__(cls, cls)

[issue45847] Port module setup to PY_STDLIB_MOD() macro and addext()

[Christian Heimes]

New submission from Christian Heimes :

bpo-45573 added the PY_STDLIB_MOD() autoconf macro, Modules/Setup.stdlib.in 
template, and setup.py helper method addext().

The macro sets up

* MODULE_{NAME}_TRUE/FALSE conditional
* MODULE_{NAME} variable with values yes, disabled, missing, or n/a
* MODULE_{NAME}_CFLAGS
* MODULE_{NAME}_LDFLAGS

Additionally there is a MODULE_{NAME}_DEPS variable with dependency information.

The Modules/Setup.stdlib.in template and addext() method consume the variables 
and set up extension compilation and linking. There is no need to look for 
headers or libraries in setup.py any more.

Let's port all modules to the new approach.

[issue45846] Incorrect name capitalisation in faq/programming

[JMcB]

New submission from JMcB :

At 
https://docs.python.org/3/faq/programming.html#how-can-i-have-modules-that-mutually-import-each-other
 it says:
van Rossum doesn’t like this approach much because the imports appear in a 
strange place, but it does work.
The V should be capitalised.

[issue6669] TarFile.getmembers fails at struct.unpack: unpack requires a string argument of length 4

[STINNER Victor]

STINNER Victor  added the comment:

File "/home/apy/ActivePython-2.6/lib/python2.6/gzip.py", line 24, in 
read32
return struct.unpack("
Date:   Tue Jan 22 17:01:59 2013 +0200

Issue #1159051: GzipFile now raises EOFError when reading a corrupted file
with truncated header or footer.
Added tests for reading truncated gzip and bzip2 files.

---


  File "/home/apy/ActivePython-2.6/lib/python2.6/tarfile.py", line 
2307, in next
self.fileobj.seek(self.offset)
  File "/home/apy/ActivePython-2.6/lib/python2.6/gzip.py", line 382, in 
seek
self.read(1024)

Moreover, gzip.GzipFile().seek() no longer calls self.read(1024):

commit 2dbc6e6bce0a29757acddd8000d55f7c844295a2
Author: Antoine Pitrou 
Date:   Sat Apr 11 00:31:01 2015 +0200

Issue #23529: Limit the size of decompressed data when reading from
GzipFile, BZ2File or LZMAFile.  This defeats denial of service attacks
using compressed bombs (i.e. compressed payloads which decompress to a huge
size).

Patch by Martin Panter and Nikolaus Rath.

IMO it's no longer possible to reproduce the gzip.error on 
gzip.GzipFile.seek(), so I close the issue as out of date.
