This is a workflow issue and already seems to have a report. I am closing this 
as third party. Please don't create issues related to workflow or one of the

[issue36539] Distutils VC 6.0 Errors When Using mingw-w64 GCC

[Dan Yeaw]

Dan Yeaw  added the comment:

lazka: Thanks for you response. You are correct, the issue was that I had a pip 
installed version of setuptools somehow. It sounds like you think that all 
issues should go downstream to fixing them in the MINGW-packages. I am OK with 
this, it just seams like there are many many issues with Python in MSYS2. 
Basics like virtualenvs aren't currently working at all. I will start 
submitting the issues I am having there with proposed fixes, and then we can 
push them upstream if we think there are things that the core Python team can 
help out with.

[issue36537] except statement block incorrectly assumes end of scope(?).

[Saim Raza]

Saim Raza  added the comment:

https://docs.python.org/3/reference/compound_stmts.html#the-try-statement says

=
except E as N:
foo
=

is converted to the following statement:

=
except E as N:
try:
foo
finally:
del N
=

In the examples in this thread, foo is 'import pdb; pdb.set_trace()'. So, I was 
expecting 'del N' to be executed only after executing foo. This implies that 
err should have been available in the scope.

Further, isn't the code execution supposed to be stopped at the set_trace() 
line and not on the next line. Should it at least respect the scope 
(indentation) and not execute the '--Return--' line event until the user 
actually executes the next line (x=1 in your example)?

[issue33775] argparse: the word 'default' (in help) is not marked as translatable

[paul j3]

paul j3  added the comment:

I haven't paid much attention to the localization issues in `argparse`.  

The issue is with the help modification done by the:

class ArgumentDefaultsHelpFormatter

help += ' (default: %(default)s)'

This formatter is a convenience, not something critical.  The programmer could 
always include that 'default' string in the help line with their preferred 
terminology.  They don't have to use this formatter to show the default values 
in their help lines.

_() is used mostly for error messages with the format 

msg = _('message %(value)s')
raise Error( msg % args)

So the following change might work:

help += _(' (default: %(default)s)')

But I'm not in a position to test it or evaluate its usefulness.

[issue36517] typing.NamedTuple does not support mixins

[Ivan Levkivskyi]

Ivan Levkivskyi  added the comment:

Hm, it looks like we can support this. I however don't think the proposed 
"patch" is the right way to fix it, since this makes the implementation with 
and without a mixin quite different.

Also I am not sure I will have time to work on this in the nearest month.

[issue36546] Add quantiles() to the statistics module

[Raymond Hettinger]

New submission from Raymond Hettinger :

It is a common and useful data analysis technique to examine quartiles, 
deciles, and percentiles. It is especially helpful for comparing distinct 
datasets (heights of boys versus heights of girls) or for comparing against a 
reference distribution (empirical data versus a normal distribution for 
example).

--- sample session ---

>>> from statistics import NormalDist, quantiles
>>> from pylab import plot

# SAT exam scores
>>> sat = NormalDist(1060, 195)
>>> list(map(round, quantiles(sat, n=4)))   # quartiles
[928, 1060, 1192]
>>> list(map(round, quantiles(sat, n=10)))  # deciles
[810, 896, 958, 1011, 1060, 1109, 1162, 1224, 1310]

# Summarize a dataset
>>> data = [110, 96, 155, 87, 98, 82, 156, 88, 172, 102, 91, 184, 105, 114, 104]
>>> quantiles(data, n=2)# median
[104.0]
>>> quantiles(data, n=4)# quartiles
[91.0, 104.0, 155.0]
>>> quantiles(data, n=10)   # deciles
[85.0, 88.6, 95.0, 99.6, 104.0, 108.0, 122.2, 155.8, 176.8]


# Assess when data is normally distributed by comparing quantiles
>>> reference_dist = NormalDist.from_samples(data)
>>> quantiles(reference_dist, n=4)
[93.81594518619364, 116.27, 138.71738814713967]

# Make a QQ plot to visualize how well the data matches a normal distribution
# plot(quantiles(data, n=7), quantiles(reference_dist, n=7))

[issue33775] argparse: the word 'default' (in help) is not marked as translatable

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

@paul.j3 I assume this is an easy issue of wrapping "default" with _() at [0]. 
There doesn't seem to be any tests for localization in argparse.

[issue36537] except statement block incorrectly assumes end of scope(?).

[Xavier de Gaye]

Xavier de Gaye  added the comment:

This is not a bug.
On the first pdb session from the OP:

True
--Return--
> (5)()->None
-> import pdb; pdb.set_trace()
(Pdb) print("err" in locals())
False  <-- BUG??

Pdb has stopped on a '--Return--' line event, so we are already outside the 
scope of the except clause and the 'err' local variable cannot be accessed 
outside the except block. The following code snippet shows that pdb stops at 
the line following the set_trace() call:

==
def foo():
try:
1/0
except Exception as err:
import pdb; pdb.set_trace()
x= 1

foo()
==

And the corresponding pdb session:

$ python foo.py
> /path/to/foo.py(6)foo()
-> x= 1
(Pdb) err
*** NameError: name 'err' is not defined
(Pdb)

[issue36529] Python from WindowsStore: can't install package using "-m pip"

[Steve Dower]

Steve Dower  added the comment:

Yeah, right now you need to also pass --local when you use -m (the bundled 
pip.exe does this automatically). Your user account does not have permission to 
install into the global site directory.

Once we update the bundled pip I can add a site-specific configuration file to 
handle both cases transparently (I had to enable it in pip first before we 
could make CPython handle it).

[issue36543] Remove old-deprecated ElementTree features (part 2)

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

The proposed PR removes old-deprecated ElementTree features.

* Methods Element.getchildren(), Element.getiterator() and 
ElementTree.getiterator() deprecated in 2.7 and 3.2. They were deprecated in 
the documentation only, and started to emit a warning in 3.8. Use list(elem) or 
iteration instead of getchildren(), methods iter() instead of getiterator().

* The xml.etree.cElementTree module deprecated in 3.3. It was deprecated 
documentation only because adding a runtime warning will cause more harm than 
removing it because of the common idiom of using it since Python 2:

try:
import xml.etree.cElementTree as ET
except ImportError:
import xml.etree.ElementTree as ET

TODO: Add a What's New entry after the start of developing 3.9.

[issue36542] Allow to overwrite the signature for Python functions

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

Currently __text_signature__ can be used for specifying signature of functions 
implemented in C. It is ignored for functions implemented in Python. The 
proposed PR allows to override the real signature of Python functions by 
setting the __text_signature__ attribute. This is needed to restore useful 
signatures in functions that use the *args hack to implement positional-only 
parameters. See the discussion for PR 12637.

[issue36533] logging regression with threading + fork are mixed in 3.7.1rc2 (deadlock potential)

[Gregory P. Smith]

Gregory P. Smith  added the comment:

Here's a PR that goes the re-initialization route rather than attempting to 
acquire/release anything other than the single module _lock.

[issue36538] _thread.interrupt_main() no longer interrupts Lock.wait

[Eryk Sun]

Eryk Sun  added the comment:

Windows doesn't implement POSIX signals in the kernel, so 
_thread.interrupt_main (i.e. PyErr_SetInterrupt) can be useful as an 
abstraction. 

Currently PyErr_SetInterrupt (Modules/signalmodule.c) doesn't set our SIGINT 
event in Windows. It was suggested in issue 29926 to replace the trip_signal 
call with raise(SIGINT). That works for Windows -- as long as we're not 
concerned about emulating Ctrl+C exactly as if the user typed it in the console 
(if we're attached to a console). In POSIX, raise(SIGINT) won't interrupt the 
main thread if it's in a blocking system call, since it targets pthread_self(), 
so PyErr_SetInterrupt can instead call kill(getpid(), SIGINT), as you suggest, 
or pthread_kill(main_thread, SIGINT). 

3.8 adds signal.raise_signal (see issue 35568), so it's possible to implement 
this in pure Python. Either way, it would be nice to keep it as a 
cross-platform function, and hopefully make it public and documented.

Another option would be to enhance our Windows implementation of os.kill to 
more closely match POSIX kill(), such that os.kill(os.getpid(), signal.SIGINT) 
is implemented as raise(SIGINT). That would be a breaking change since 
currently it calls TerminateProcess (an abrupt termination like POSIX SIGKILL).

[issue36440] more helpful diagnostics for parser module

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Since the parser module did not work in 3.7, I think this will not harm. But in 
general new features (including changes in error messages) are added only in 
the developed version.

[issue36532] Example of logging.formatter with new str.format style

[spaceman_spiff]

spaceman_spiff  added the comment:

I was under the impression that this was all it takes to use loggers with the 
normal string.format syntax.
e.g.:
   log.info('{}', 'Test')
Turns out when I tested it I used f-strings in the first parameters - so I got 
it wrong.
Imho this can be closed and the pr rejected.
Sorry for wasting your time :)

[issue36539] Distutils VC 6.0 Errors When Using mingw-w64 GCC

[Christoph Reiter]

Christoph Reiter  added the comment:

MSYS2 patches setuptools to work with GCC and the MSYS2 Python, so you can't 
use setuptools as is from pip.

See 
https://github.com/msys2/MINGW-packages/tree/master/mingw-w64-python-setuptools 
for the current set of patches.
