[issue40377] APPDATA location in Microsoft Store version
New submission from Stephan Troyer : In Microsoft Store apps, access to %APPDATA% and %LOCALAPPDATA% gets transparently redirected to an app specific location (such as %LOCALAPPDATA%\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\). This is perfect for saving settings etc. of Python scripts and packages, however that doesn't work, when the unredirected paths are returned by a sandboxed Python script and consumed by a 3rd party tool. One example for the issue created by that is Jupyter, which saves its kernel settings to %appdata% and returns that path when using the command `jupyter kernelspec list`. However other applications which rely on that output can't access the resulting paths (since their file access doesn't get redirected). Would it make sense to add some API for accessing the UWP APIs ApplicationData.Current.LocalFolder and ApplicationData.Current.RoamingFolder, which provide a folder path, which doesn't get redirected?

[issue35621] asyncio.create_subprocess_exec() only works with main event loop
New submission from Stephan Hohe :
`asyncio.create_subprocess_exec()` accepts a `loop` parameter, but doesn't use
it to watch the child process. Instead uses
`get_event_loop_policy().get_child_watcher()`, which doesn't doesn't know about
`loop` but tries to use the current default event loop.
This fails if there is no current event loop or if that loop isn't running:
```
import asyncio
async def action(loop):
proc = await asyncio.create_subprocess_exec('echo', loop=loop)
await proc.wait()
loop = asyncio.new_event_loop()
loop.run_until_complete(action(loop))
loop.close()
```
This crashes because the main event loop never was created:
Traceback (most recent call last):
File "sample.py", line 8, in
loop.run_until_complete(action(loop))
File "/home/sth/devel/cpython.vanilla/Lib/asyncio/base_events.py", line 589,
in run_until_complete
return future.result()
File "sample.py", line 4, in action
proc = await asyncio.create_subprocess_exec('echo', loop=loop)
File "/home/sth/devel/cpython.vanilla/Lib/asyncio/subprocess.py", line 213,
in create_subprocess_exec
transport, protocol = await loop.subprocess_exec(
File "/home/sth/devel/cpython.vanilla/Lib/asyncio/base_events.py", line 1542,
in subprocess_exec
transport = await self._make_subprocess_transport(
File "/home/sth/devel/cpython.vanilla/Lib/asyncio/unix_events.py", line 193,
in _make_subprocess_transport
watcher.add_child_handler(transp.get_pid(),
File "/home/sth/devel/cpython.vanilla/Lib/asyncio/unix_events.py", line 924,
in add_child_handler
raise RuntimeError(
RuntimeError: Cannot add child handler, the child watcher does not have a loop
attached
If we do have a current event loop, for example by calling
`asyncio.get_event_loop()` before creating out own loop, then we don't get an
error, but the program hangs indefinitely since that loop isn't running.
Expected behavior would be that the loop given to create_subprocess_exec() is
used to watch the child process.

[issue24379] Add operator.subscript as a convenience for creating slices
Stephan Hoyer added the comment: Raymond, Tal and Guido -- do any of you work routinely with multi-dimensional arrays? In my experience as someone who uses Python everyday for numerical computing (and has been doing so for many years), the need for an operator like this comes up with some regularity. With multi-dimensional indexing, this allows lets you cut down quite a bit on boilerplate, e.g., compare subscript[:, 0, ::-1] vs (slice(None), 0, slice(None, None, -1)) It's absolutely true that subscript is an easy four line recipe, and indeed a form of this recipe is already included in both NumPy and pandas. But I think this is a case where the lack of a common idiom is actively harmful. I do multi-dimensional indexing in using at least four different libraries (pandas, xarray, numpy and tensorflow), and it feels wrong to use a utility from numpy/pandas for other projects. I could write my own version of operator.subscript in each project (and yes, I've done so before), but for any individual use case it's less hassle to write things out the long way. In practice, the preferred way to write such long expressions seems to be to redundantly repeat indexing operations, e.g., x[:, 0, ::-1] y[:, 0, ::-1] rather than index = subscript[:, 0, ::-1] x[index] y[index] This is definitely non-ideal from a readability perspective. It's no longer immediately clear that these arrays are being indexed in the same way, and any changes would need to be applied twice. -- nosy: +Stephan Hoyer ___ Python tracker <https://bugs.python.org/issue24379> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue30676] Potential for GIL deadlock on Windows in threadmodule acquire_lock
New submission from Stephan R.A. Deibel: In acquire_timed in _threadmodule.c (used to implement threading lock acquire()) there is an optimization from https://github.com/python/cpython/commit/e75ff35af2b6c85d48c68b95f295aeac7396b162 that says it first tries non-blocking lock w/o releasing the GIL. However, it seems that this call can block on Windows. The call to PyThread_acquire_lock_timed(lock, 0, 0) (w/o releasing GIL) on Windows calls EnterNonRecursiveMutex which in turn, in the _PY_USE_CV_LOCKS impl, immediately calls PyMUTEX_LOCK as if it's not going to block. However, various implementations of this seem like they can block. Specifically, the impls of PyMUTEX_LOCK that end up using AcquireSRWLockExclusive and EnterCriticalSection both block. The only case that is correct (does not block) is when !_PY_USE_CV_LOCKS where EnterNonRecursiveMutex() instead calls WaitForSingleObjectEx() with the zero timeout. This seems like an incorrect potential for GIL deadlock, because the thread blocks without releasing GIL. Shouldn't it ultimately be using TryAcquireSRWLockExclusive and TryEnterCriticalSection in these two cases? This seems like an issue on Windows only. The pthreads implementations look like they correctly handle timeout of 0 sent to PyThread_acquire_lock_timed(). -- components: Library (Lib), Windows messages: 296088 nosy: paul.moore, sdeibel, steve.dower, tim.golden, zach.ware priority: normal severity: normal status: open title: Potential for GIL deadlock on Windows in threadmodule acquire_lock type: behavior versions: Python 3.4, Python 3.5, Python 3.6 ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30676> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Our actual use case for NumPy involved writing a mixin that look more like this, that expects a specified method to implement arithmetic, i.e., class NDArrayOperatorsMixin: def __add__(self, other): return self._calculate(np.add, self, other) def __radd__(self, other): return self._calculate(np.add, other, self) ... # repeat for all special methods class A(NDArrayOperatorsMixin): def _calculate(self, op, *args): if not all(isinstance(arg, A) for arg in args): return NotImplemented ... # implement calculation class B(A): def _calculate(self, op, *args): ... # something different In A() + B(), B never gets the chance to override A's implementation of __add__ via _calculate, because it overrode a different method (_calculate) which happens to contain the *implementation* for __radd__, but not __radd__ itself.

[issue30140] Binary arithmetic does not always call subclasses first
Stephan Hoyer added the comment: Posted to python-ideas: https://mail.python.org/pipermail/python-ideas/2017-April/045451.html Mark -- just out of curiosity, could you point me to where this logic is implemented in CPython's source?

[issue30140] Binary arithmetic does not always call subclasses first
New submission from Stephan Hoyer:
We are writing a system for overloading NumPy operations (see PR [1] and design
doc [2]) that is designed to copy and extend Python's system for overloading
binary operators.
The reference documentation on binary arithmetic [3] states:
> Note: If the right operand's type is a subclass of the left operand’s type
> and that subclass provides the reflected method for the operation, this
> method will be called before the left operand’s non-reflected method. This
> behavior allows subclasses to override their ancestors’ operations.
However, this isn't actually done if the right operand merely inherits from the
left operand's type. In practice, CPython requires that the right operand
defines a different method before it defers to it. Note that the behavior is
different for comparisons, which defer to subclasses regardless of whether they
implement a new method [4].
I think this behavior is a mistake and should be corrected. It is just as
useful to write generic binary arithmetic methods that are well defined on
subclasses as generic comparison operations. In fact, this is exactly the
design pattern we propose for objects implementing special operators like NumPy
arrays (see NDArrayOperatorsMixin in [1] and [2]).
Here is a simple example, of a well-behaved that implements addition by
wrapping its value and returns NotImplemented when the other operand has the
wrong type:
class A:
def __init__(self, value):
self.value = value
def __add__(self, other):
if not isinstance(other, A):
return NotImplemented
return type(self)(self.value + other.value)
__radd__ = __add__
def __repr__(self):
return f'{type(self).__name__}({self.value!r})'
class B(A):
pass
class C(A):
def __add__(self, other):
if not isinstance(other, A):
return NotImplemented
return type(self)(self.value + other.value)
__radd__ = __add__
A does not defer to B:
>>> A(1) + B(1)
A(2)
But it does defer to C, which defines new methods (literally copied/pasted) for
__add__/__radd__:
>>> A(1) + C(1)
C(2)
With the current behavior, special operator implementations need to explicitly
account for the possibility that they are being called from a subclass by
returning NotImplemented. My guess is that this is rarely done, which means
that most of these methods are broken when used with subclasses, or subclasses
needlessly reimplement these methods.
Can we fix this logic for Python 3.7?

Stephan R.A. Deibel sdei...@wingware.com added the comment: Ah, thanks, there it is... I thought this must be dealt with somewhere but couldn't find it. Maybe should add something to the 'exec' statement docs http://docs.python.org/py3k/library/functions.html#exec to reference this (from a usability-of-docs standpoint). BTW, my code already sends the namespaces to exec (from current stack frame; it's part of a debugger) and probably would break other cases to alter this.

[issue9925] Idle doesn't launch
New submission from Stephan Bellegy stephan.bell...@gmail.com: Environment is Win7, 32bits. User has Admin rights. I haven't coded in Python at the office for a while and had a little script to write. Thus, I decided to upgrade from 2.6 to 2.7 (that is : 2.6 was already there and functionnal as far as I remind it and was the first install of Python on the new PC) 2.7 installation run without problems nor warnings, as usual. But then Idle didn't launch. No message. No Python process running in the background. So I launched it via a shell and grabbed an error message : IOError: [Errno 13] Permission denied: 'C:\\Users\\Foobar\\.idlerc\\recent-files.lst' Then I googled and found http://bugs.python.org/issue1743 Deleting ~\.idlerc\ did the trick and now Idle runs fine. So the bug 1743 isn't clearly solved and this is what I suspect : My Windows is localized in French. From the DOS Shell, the User Dir is C:\Users\FOOBAR but Windows Explorer displays in its address bar : C:\Utilisateurs\FOOBAR Maybe the problem comes from here ? -- components: IDLE, Installation messages: 117184 nosy: Stephan.Bellegy priority: normal severity: normal status: open title: Idle doesn't launch versions: Python 2.6, Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9925 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue2198] code_hash() can be the same for different code objects
New submission from Stephan R.A. Deibel: The algorithm in code_hash() in codeobject.c can return the same hash value for different code objects. Presumably distinct code objects should be very unlikely to have the same hash value. This bug affected our debugger before we worked around it, and it could affect other things like profilers.
