[issue44356] Abstract enum mixins not allowed

[Jordan Ephron]

New submission from Jordan Ephron :

Prior to 3.8 it was possible to create "abstract" enums (without members) and 
mix them together. To motivate with an example, perhaps we're modeling an API 
and want to be robust in the face of inconsistent casing


class CaseInsensitiveStrEnum(str, Enum):
@classmethod
def _missing_(cls, value):
for member in cls._member_map_.values():
if member._value_.lower() == value.lower():
return member
return super()._missing_(value)


and perhaps we also want to be robust in response to extensibility


class LenientStrEnum(str, Enum):
@classmethod
def _missing_(cls, value):
logger.warning(
f"[{cls.__name__}] encountered an unknown value!\n"
f"Luckily I'm a LenientStrEnum, so I won't crash just yet.\n"
f"You might want to add a new case though.\n"
f"Value was: '{value}'"
)
return UnexpectedStr(value)


but we also want to model some known good set of values, so mixing together the 
abstract enums we'd get something like


class JobStatus(CaseInsensitiveStrEnum, LenientStrEnum):
ACTIVE = "active"
PENDING = "pending"
TERMINATED = "terminated"

However, due to the resolution of https://bugs.python.org/issue39587 this no 
longer works, instead producing:

TypeError: 'JobStatus': too many data types: [, ]


The relevant change is

https://github.com/ethanfurman/cpython/commit/bff01f3a3aac0c15fe8fbe8b2f561f7927d117a1

I believe that if we made `data_types` a set rather than a list then the 
example would become valid once again.

[issue39345] Py_Initialize Hangs on Windows 10

[Duane Griffin]

Duane Griffin  added the comment:

I can reproduce this on Windows 10 with Python 3.9. See attached source. At 
least for us, it is hanging when one thread is doing a read on the file 
descriptor while a second calls Py_Initialize (or just dup directly).

The windows kernel call stack shows the dup call is waiting on a critical 
section, while the thread reading from stdin is waiting in ReadFile. I can get 
a full stack trace from WinDbg if it is helpful, but hopefully the attached 
code should be enough to reproduce the problem at will for anyone interested.

If stdin is receiving input, or is closed, then the read call will complete and 
unblock dup in due course. However if not then it will hang indefinitely.

If we can fix this to work reliably in Python that would be great. Otherwise, 
or in the meantime, we could just add a note to the documentation. We are going 
to try and work-around it by using a different file descriptor instead of 
stdin. Other applications might be able to avoid IO using stdin until after 
python is initialised.

[issue38323] asyncio: MultiLoopWatcher has a race condition (test_asyncio: test_close_kill_running() hangs on AMD64 RHEL7 Refleaks 3.x)

[Yury Selivanov]

Yury Selivanov  added the comment:

>  MultiLoopChildWatcher must ensures that the event loop is awaken when it

> _UnixSelectorEventLoop.add_signal_handler(). Maybe MultiLoopChildWatcher 
> could reuse this function, rather than calling directly signal.signal().

I think this is a good idea. MultiLoopChildWatcher could use setwakeupfd with 
some no-op callback just to wakeup the loop.

[issue40468] IDLE: configdialog tab rearrange

[Terry J. Reedy]

Terry J. Reedy  added the comment:

PR-26618 wraps the extension functions in a new class, ExtPage, and then moves 
the new class after GenPage.

I verified that replacing the indent slider with a spinbox results in the 
dialog being shorter by the full height of the helplist frame.  I will do that 
(or use a plain entry box) when I move it Window Preferences, after splitting 
GenPage.

[issue44355] Allow spaces in format strings

[Steven D'Aprano]

New submission from Steven D'Aprano :

Format strings should allow spaces around keys and indices. This might be as 
simple as running str.strip() on the contents of curly braces?

Aside from indentation and newlines, in most other contexts whitespace is 
insignificant. E.g. in subscripting `seq[ index ]`. But format strings treat 
spaces as part of the index or key, which is surprising.

f-strings, on the other hand, already allow spaces around expressions and keys:

>>> name = 'Brian'
>>> f'{ name.upper() }'
'BRIAN'


Examples:

'{ }'.format(30)
Expect to get '30'
but get KeyError: ' '


'{ 0 }'.format(30)
Expect to get '30'
but get KeyError: ' 0 '

'{ x }'.format(x=30)
Expect to get '30'
but get KeyError: ' x '

[issue44350] IDLE: support Command-click on window title on macOS

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Documented as macOS specific at https://www.tcl.tk/man/tcl8.6/TkCmd/wm.htm.  
But I would not know about C-click from "Specifies the path of the file 
referenced as the window proxy icon (which can be dragged and dropped in lieu 
of the file's finder icon). "

IDLE document windows already have the absolute path in the title.  There is 
only an issue if it is too long for the space, such as when editing installed 
idlelib test files.  I don't know what will happen if/when you use tabbed 
windows.

In the meanwhile, it would be easy to add
if long and sys.platform == 'darwin':
# Only valid as long as 'long' is absolute path.
self.top.wm_attributes("-titlepath", long)
to the end of editor.EditorWindow.saved_change_hook.

Ned or Ronald, is this worth it?  Is there any downside to this?

[issue44354] ssl deprecation warnings erganomics

[Thomas Grainger]

New submission from Thomas Grainger :

The ssl module OP_NO_* deprecation warning message is slightly wrong: The error 
message prints out "is deprecated is deprecated" because of an earlier format 
template

There's a colon in the warning message `ssl module:` and that makes it 
difficult to use in simplefilter

The NPN deprecation warnning raises a UserWarning instead of DeprecationWarning

see also UserWarning: ssl module: NPN is deprecated, use ALPN instead

[issue44246] 3.10 beta 1: breaking change in importlib.metadata entry points

[Jason R. Coombs]

Jason R. Coombs  added the comment:

As mentioned in msg394775, I'd like to decouple the performance concerns from 
the original incompatibility. I recognize that performance regressions are in 
their own way a form of incompatibility, but there have been a lot of changes 
to entry points with respect to performance, both prior to beta 1 and in beta 
2, including changes that intentionally traded performance for correctness 
(https://github.com/python/importlib_metadata/pull/281).

To that end, I've filed https://github.com/python/importlib_metadata/issues/324 
to track the concerns.

[issue44352] Native Windows Python builds running on Europe/Moscow TZ report wrong time from datetime.datetime.now when there is TZ environment variable also set to Europe/Moscow

[Mike Kaganski]

New submission from Mike Kaganski :

On a Windows 10 system, which TZ is set to Moscow (UTC+3), I use a native 
Windows Python build (as opposed to e.g. one from Cygwin). Specifically, I 
tested both custom Python build created by LibreOffice project, as well as the 
Python by Python Software Foundation available from MS Store [1].

1. Open command prompt on Windows (cmd.exe).
2. Execute 'set TZ=Europe/Moscow'
3. Execute 'python'
4. In the Python prompt, execute 'import datetime'
5. Execute 'datetime.datetime.now()'

The result of this is a time that is two hours off, e.g.

> datetime.datetime(2021, 6, 8, 19, 59, 21, 925240)

instead of proper

> datetime.datetime(2021, 6, 8, 21, 59, 21, 925240)

which appears when step #2 is skipped.
Possibly Python takes both system time zone information *and* the environment 
variable into account when calculating the time. I suppose it should only 
consider one or the other, not both.

Note that the problem does not happen with Cygwin's Python, which works fine 
with the same TZ environment variable value.

For a real-life problem that results from this, see case at [2], where unit 
test is failing only from 00:00 till 02:00 on my local system, obviously 
telling me that I should sleep at that time, not try to run unit tests :-)

[issue44349] Edge case in pegen's error displaying with non-utf8 lines

[Ammar Askar]

New submission from Ammar Askar :

The AST currently stores column offsets for characters as byte-offsets. 
However, when displaying errors, these byte-offsets must be turned into 
character-offsets so that the characters line up properly with the characters 
on the line when printed. This is done with the function 
`byte_offset_to_character_offset` 
(https://github.com/python/cpython/blob/fdc7e52f5f1853e350407c472ae031339ac7f60c/Parser/pegen.c#L142-L161)
 which assumes that the line is UTF8 encoded.

However, consider a file like this:

  '¢¢¢¢¢¢' + f(4, 'Hi' for x in range(1)) # This line has a SyntaxError

This prints

  File "test-normal.py", line 1
'¢¢¢¢¢¢' + f(4, 'Hi' for x in range(1)) # This line has a SyntaxError
  ^^
  SyntaxError: Generator expression must be parenthesized

as expected.


However if we use a custom source encoding line:

  # -*- coding: cp437 -*-
  '¢¢¢¢¢¢' + f(4, 'Hi' for x in range(1)) # This line has a SyntaxError

it ends up printing out

  File "C:\Users\ammar\junk\test-utf16.py", line 2
'¢¢' + f(4, 'Hi' for x in range(1)) # This line has a SyntaxError
  ^^
  SyntaxError: Generator expression must be parenthesized

where the carets/offsets are misaligned with the actual characters. This is 
because the string "¢" has the display width of 2 characters and encodes to 2 
bytes in cp437 but when interpreted as utf-8 is the single character "¢" with a 
display width of 1.

Note that this edge case is relatively hard to trigger because ordinarily what 
will happen here is that the call to PyErr_ProgramTextObject will fail because 
it tries to decode the line as utf-8: 
https://github.com/python/cpython/blob/ae3c66acb89a6104fcd0eea760f80a0287327cc4/Python/errors.c#L1693-L1696
 after which the error handling logic uses the tokenizer's internal buffer 
which has a proper utf-8 string.
So this bug requires the input to be valid as both utf-8 and the source 
encoding.

[issue44348] test_exceptions.ExceptionTests.test_recursion_in_except_handler stack overflow on Windows debug builds

[Steve Dower]

Steve Dower  added the comment:

> Decrease the global recursion limit only for windows debug.

This is already what we do, so if someone has increased stack usage, they 
should also decrease the value here.

Hopefully the non-debug value doesn't have to be reduced. In that case, it's 
worth looking at the stack allocations to reduce it (e.g. I once fixed this by 
moving a rarely used buffer into a dynamic allocation rather than a local, 
which saved about 1KB/frame).

[issue44344] Documentation for pow() should include the possibility of complex numbers as a return type

[Mark Dickinson]

Mark Dickinson  added the comment:

[Dennis]

> I think the relevant property is that the exponent is not an integer

Yep: the delegation to complex pow kicks in after handling infinities and nans, 
and only for strictly negative base (-0.0 doesn't count as negative for this 
purpose) and non-integral exponent.

Here's the relevant code: 
https://github.com/python/cpython/blob/257e400a19b34c7da6e2aa500d80b54e4c4dbf6f/Objects/floatobject.c#L773-L782

To avoid confusion, we should probably not mention fractions like `1/3` and 
`4/3` as example exponents in the documentation, since those hit the 
What-You-See-Is-Not-What-You-Get nature of binary floating-point. 
Mathematically, `z^(1/3)` is a very different thing from 
`z^(6004799503160661/18014398509481984)` for a negative real number `z`, and 
the latter is what's _actually_ being computed with `z**(1/3)`. The advantage 
of the principal branch approach is that it's continuous in the exponent, so 
that `z^(1/3)` and `z^(6004799503160661/18014398509481984)` only differ by a

[issue44310] Document that lru_cache uses hard references

[Henk-Jaap Wagenaar]

Henk-Jaap Wagenaar  added the comment:

Reading this bug thread last week made me realize we had made the following 
error in our code:


class SomethingView():
@functools.lru_cache()
def get_object(self):
return self._object


Now, as this class was instantiated for every (particular kind of) request to a 
webserver and this method called (a few times), the lru_cache just kept filling 
up and up. We had been having a memory leak we couldn't track down, and this 
was it.

I think this is an easy mistake to make and it was rooted, not so much in hard 
references though (without that though, it would have not leaked memory) but 
because of the fact the cache lives on the class and not the object.

[issue44246] 3.10 beta 1: breaking change in importlib.metadata entry points

[Anthony Sottile]

Anthony Sottile  added the comment:

here's the performance regressions, they affect any callers of 
`distributions()` and are even worse on callers of the new apis.

a call to distributions() is about 3x slower than in 3.9

here is the setup I am using:

virtualenv venv39 -ppython3.9
venv39/bin/pip install flake8 pytest twine pre-commit
virtualenv venv310 -ppython3.10
venv310/bin/pip install flake8 pytest twine pre-commit

to test just the `distributions()` call I'm using the following:

```console
$ venv39/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import 
entry_points' 'entry_points()'
20 loops, best of 20: 12.5 msec per loop
$ venv310/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import 
entry_points' 'entry_points()'
20 loops, best of 20: 36.7 msec per loop
```

this is a less-extreme example, many applications have more dependencies 
installed -- but even in this case this is adding ~24ms startup to any 
application using `entry_points()` -- and it gets worse

the return value of `entry_points()` alone isn't all that useful, next an 
application needs to retrieve its entry points.  let's start for the somewhat 
normal case of retrieving a single category of entry points:

```console
$ venv39/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import 
entry_points' 'entry_points()["flake8.extension"]'
20 loops, best of 20: 12.7 msec per loop
$ venv310/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import 
entry_points' 'entry_points(name="flake8.extension")'
20 loops, best of 20: 37.1 msec per loop
$ venv310/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import 
entry_points' 'entry_points().select(group="flake8.extension")'
20 loops, best of 20: 37.1 msec per loop
```

again, 3x slower and very real time to the end user (~24-25ms)

now let's show an example usage that something like flake8 uses where multiple 
groups are requested (this is common for apps and plugin systems which provide 
multiple distinct functionalities)

```console
$ venv39/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import 
entry_points' 'eps = entry_points(); eps["flake8.extension"]; 
eps["flake8.report"]'
 
20 loops, best of 20: 12.6 msec per loop
$ venv310/bin/python -m timeit -n 20 -r 20 -s 'from importlib.metadata import 
entry_points' 'eps = entry_points(); eps.select(group="flake8.extension"); 
eps.select(group="flake8.report")'
20 loops, best of 20: 38.2 msec per loop
```

also slower, but an additional ms per call to `.select(...)`


and it only gets worse with more and more packages installed

here's the versions I'm using to ensure they are up to date:

```console
$ venv39/bin/python --version --version
Python 3.9.5 (default, May 19 2021, 11:32:47) 
[GCC 9.3.0]
$ venv310/bin/python --version --version
Python 3.10.0b2 (default, Jun  2 2021, 00:22:18) [GCC 9.3.0]
```

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

That won't fix half of the Windows failures because the stack overflow you are 
seeing are for C to C calls if I am not mistaken. This happens on very deep 
calls when converting Python objects to C objects. There are no Python frames 
involved in that case IIRC.

Mark Shannon  added the comment:

Pablo,

Is there a bpo issue for the buildbot failures on Windows?
The failures I've been seeing are C stack overflows.

Long term, I expect to fix it by decoupling the C and Python stacks.
In the short term I have a couple of changes that might get it working again

ِAbdulrahman ِShawa  added the comment:

hello guys 
I am facing problem with my sqlite3 database when i make changes it saves the 
changes for almost 13 hours and then retakes back all the changes that i made, 
i am using two threads in my code and i am not committing the data but i set 
the isolation mode to None,
i was using the same queries with mysql database with setting autocommit to on 
and it was working fine what could be the problem in your opinion?
we searched and ask a lot about this issue but nothing was helpful.

[issue43693] Logically merge cell and locals array. They are already contiguous in memory

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

The problem seems to be that The problem is that PyFrame_LocalsToFast(frame, 
1); calls into PyFrame_LocalsToFast where co->co_nlocals has a value of 3, and 
this causes co->co_cell2arg[i - co->co_nlocals]; to access outside the bounds 
of the array.

As this change is affecting all tests (there are many tests in the test suite 
that fail with a buffer overflow in the ASAN builds) I opened PR 26597 to 
revert commit commit631f9938b1604d4f893417ec339b9e0fa9196fb1. As always, 
please, recommit commit631f9938b1604d4f893417ec339b9e0fa9196fb1 once this 
issues are fixed.

To reproduce these failures locally you can:

$ export ASAN_OPTIONS=detect_leaks=0:allocator_may_return_null=1:handle_segv=0
$ ./configure --with-address-sanitizer --without-pymalloc
$ make -j -s
$ ./python -m test test_sys_settrac

Eric, I saw thay you ran the buildbots on your PR (thanks a lot), but something 
has gone wrong in some of them and they didn't run correctly. For example:

https://buildbot.python.org/all/#/builders/581/builds/58

I'm investigating why that this. Meanwhile, could you take a look? We have 
already some problems on windows and we don't want more stuff to pile up.
