[issue39606] Regression: it should be possible to close async iterators multiple times

2020-02-10 Thread Nathaniel Smith



New submission from Nathaniel Smith :

In bpo-39386, the 'aclose' method for async generators was fixed so that the 
following broken code would correctly raise an error:

# -- bad code --
async def agen_fn():
yield

async def do_bad_thing():
agen = agen_fn()
aclose_coro = agen.aclose()
await aclose_coro
# Should raise RuntimeError:
await aclose_coro

asyncio.run(do_bad_thing())

# -

However, the merged fix also broke the following correct code, which should 
*not* raise an error:

# -- good code --
async def agen_fn():
yield

async def do_good_thing():
agen = agen_fn()
await agen.aclose()
# Should *not* raise an error, but currently does in Python dev branches:
await agen.aclose()

asyncio.run(do_good_thing())

# 

It's not supported to iterate the same coroutine object twice. However, making 
two *independent* calls to aclose should return two independent coroutine 
objects, and it should be legal to iterate over each object once.

This can also occur even if there's only a single call to 'aclose'. For 
example, this is the recommended idiom for making sure that an async generator 
correctly closes all its resources:

# -- good code --
async def agen_fn():
yield

async def careful_loop():
agen = agen_fn()
try:
async for _ in agen:
pass
finally:
await agen.aclose()

asyncio.run(careful_loop())

# ---

On released Python, the code above runs correctly. On the latest Python dev 
branches, it raises a RuntimeError.

So basically the problem is that the fix for bpo-39386 is storing the "was 
aclose iterated?" state on the async generator object, but in fact it needs to 
be stored on the aclose coroutine object.

You can see from Karthikeyan's post how it's supposed to work, and how it does 
work in his example. It may be that something else is overwriting the prompt in 
your environment - we can't tell without knowing what's in your .bashrc, 
.profile etc.

[issue39605] Fix some casts to not cast away const

2020-02-10 Thread Andy Lester



New submission from Andy Lester :

gcc -Wcast-qual turns up a number of instances of casting away constness of 
pointers.  Some of these can be safely modified, by either:

* Adding the const to the type cast, as in:

-return _PyUnicode_FromUCS1((unsigned char*)s, size);
+return _PyUnicode_FromUCS1((const unsigned char*)s, size);

* Removing the cast entirely, because it's not necessary (but probably was at 
one time), as in:

-PyDTrace_FUNCTION_ENTRY((char *)filename, (char *)funcname, lineno);
+PyDTrace_FUNCTION_ENTRY(filename, funcname, lineno);

These changes will not change code, but they will make it much easier to check 
for errors in consts.

[issue38324] [Windows] test_locale and test__locale failures on Windows

2020-02-10 Thread Eryk Sun


Eryk Sun  added the comment:

> On Windows 10 (version 1903), ANSI code page 1252, OEM code page 437, 
> LC_CTYPE locale "French_France.1252"

The CRT default locale (i.e. the empty locale "") uses the user locale, which 
is the "Format" value on the Region->Formats tab. It does not use the system 
locale from the Region->Administrative tab. 

The default locale normally uses the user locale's ANSI codepage, as returned 
by GetLocaleInfoEx(LOCALE_NAME_USER_DEFAULT, LOCALE_IDEFAULTANSICODEPAGE, ...). 
But if the active codepage of the process is UTF-8, then GetACP(), GetOEMCP(), 
and setlocale(LC_CTYPE, "") all use UTF-8 (i.e. CP_UTF8, i.e. 65001). The 
active codepage can be set to UTF-8 either at the system-locale level or in the 
application-manifest. For example, with the active codepage setting in the 
manifest:

C:\>python.utf8.exe -q

>>> from locale import setlocale, LC_CTYPE
>>> setlocale(LC_CTYPE, "")
'English_Canada.utf8'

>>> kernel32 = ctypes.WinDLL('kernel32', use_last_error=True)
>>> kernel32.GetACP()
65001
>>> kernel32.GetOEMCP()
65001

A default locale name can also specify the codepage to use. It could be UTF-8, 
a particular codepage, ".ACP" (ANSI), or ".OCP" (OEM). "ACP" and "OCP" have to 
be in upper case. For example:

>>> setlocale(LC_CTYPE, '.utf8')
'English_Canada.utf8'
>>> setlocale(LC_CTYPE, '.437')
'English_Canada.437'

>>> setlocale(LC_CTYPE, ".ACP")
'English_Canada.1252'
>>> setlocale(LC_CTYPE, ".OCP")
'English_Canada.850'

Otherwise, if you provide a known locale -- using full names, or three-letter 
abbreviations, or from the small set of locale aliases, then setlocale queries 
any missing values from the NLS database. 

One snag in the road is the set of Unicode-only locales, such as "Hindi_India". 
Querying the ANSI and OEM codepages for a Unicode-only locale respectively 
returns CP_ACP (0) and CP_OEMCP (1). It used to be that the CRT would end up 
using the system locale for these cases. But recently ucrt has switched to 
using UTF-8 for these cases. For example:

>>> setlocale(LC_CTYPE, "Hindi_India")
'Hindi_India.utf8'

That brings us to the case of modern Windows BCP-47 locale names, which usually 
lack an implicit encoding. For example:

>>> setlocale(LC_CTYPE, "hi_IN")
'hi_IN'

The current CRT codepage can be queried via __lc_codepage_func:

>>> import ctypes; ucrt = ctypes.CDLL('ucrtbase', use_errno=True)
>>> ucrt.___lc_codepage_func()
65001

With the exception of Unicode-only locales, using a modern name without an 
encoding defaults to the named locale's ANSI codepage. For example:

>>> setlocale(LC_CTYPE, "en_CA")
'en_CA'
>>> ucrt.___lc_codepage_func()
1252

The only encoding allowed in BCP-47 locale names is ".utf8" or ".utf-8" (case 
insensitive):

>>> setlocale(LC_CTYPE, "fr_FR.utf8")
'fr_FR.utf8'
>>> setlocale(LC_CTYPE, "fr_FR.UTF-8")
'fr_FR.UTF-8'

No other encoding is allowed with this form. For example:

>>> try: setlocale(LC_CTYPE, "fr_FR.ACP")
... except Exception as e: print(e)
...
unsupported locale setting
>>> try: setlocale(LC_CTYPE, "fr_FR.1252")
... except Exception as e: print(e)
...
unsupported locale setting

As to the "tr_TR" locale bug, the Windows implementation is broken due to 
assumptions that POSIX locale names are directly supported. A significant 
redesign is required to connect the dots.

>>> from locale import getlocale
>>> setlocale(LC_CTYPE, 'tr_TR')
'tr_TR'
>>> ucrt.___lc_codepage_func()
1254

>>> getlocale(LC_CTYPE)
('tr_TR', 'ISO8859-9')

Codepage 1254 is similar to ISO8859-9, except, in typical fashion, Microsoft 
assigned most of the upper control range 0x80-0x9F to an assortment of 
characters it deemed useful, such as the Euro symbol "€". The exact codepage 
needs to be queried via __lc_codepage_func() and returned as ('tr_TR', 
'cp1254'). 

Conversely, setlocale() needs to know that this BCP-47 name does not support an 
explicit encoding, unless it's "utf8". If the given codepage, or an associated 
alias, doesn't match the locale's ANSI codepage, then the locale name has to be 
expanded to the full name "Turkish_Turkey". The long name allows specifying an 
arbitrary codepage. 

For example, say we have ('tr_TR', 'ISO8859-7'), i.e. Greek with Turkish locale 
rules. This transforms to the closest approximation ('tr_TR', '1253'). When 
setlocale queries the OS, it will find that the ANSI codepage is actually 1254, 
so it cannot use "tr_TR" or "tr-TR". It needs to expand to the long form:

>>> setlocale(LC_CTYPE, 'Turkish_Turkey.1253')
'Turkish_Turkey.1253'

[issue39601] brace escapes are not working in formatted string literal format specifications

2020-02-10 Thread Chris Wilcox



Chris Wilcox  added the comment:

Double curly braces do not indicate to not process the inner content. They 
indicate to include a literal curly brace. That said, I think there may be 
something not quite correct.

I came up with an example based on the example in the format specifiers section 
of the PEP.

>From the PEP.
```
>>> width = 10
>>> precision = 4
>>> value = decimal.Decimal('12.34567')
>>> f'result: {value:{width}.{precision}}'
'result:  12.35'
```
The template in this instance is "10.4"

If we leave the sample the same, but don't wrap width or precision in single 
curly braces,
```
>>> f'result: {value:width.precision}'
```
I would expect the template "width.precision".

Further, I would expect
```
>>> f'result: {value:{{width}}.{{precision}}}'
```
to have a template of "{width}.{precision}". This is not the case.


Here is some code that should demonstrate this.
```
class Decimal:
def __init__(self, value):
pass
def __format__(self, template):
return template
width = 10
precision = 4
value = Decimal('12.34567')
print("Expect Template to be '10.4' (TRUE)")
print(f'result0: {value:{width}.{precision}}')
print("Expect Template to be 'width.precision' (TRUE)")
print(f'result1: {value:width.precision}')
print("Expect Template to be '{width}.{precision}' (FALSE)")
print(f'result2: {value:{{width}}.{{precision}}}') # ACTUAL: {10}.{4}
```

Terry J. Reedy  added the comment:

Cheryl, it appears that only 'weight' words are deleted.  For a given family, 
Tk only has a (user) settable 'bold', so other weight options must be 'baked 
in' to the family.  Perhaps X11 allows more weight settings within a family, 
even if not exposed in Tk.

[issue39600] idle_test: test_fontlist_key() fails if two font families have the same name



Terry J. Reedy  added the comment:

font.names() lists 'symbolic' family names guaranteed to exist.  
'TkDefaultFont' is the default Text widget font on a particular OS.  IDLE 
replaces that with 'TkFixedFont', which is translated to the actual family name 
on each OS: Courier on Windows (ugh) and something like Monaco on macOS.

Thank you for the additional information.  For *nix users, removing the useless 
duplicates should be an improvement.  (This is aside from the test issue, which 
could have been fixed otherwise: perhaps by inserting 'TestFont' at the top of 
the list and making other adjustments.)

Here's the example I ran, that indeed fails in Python 3.8 and Python 3.9 (with 
different errors) and works in Python 3.7. 

from unittest.mock import MagicMock


class CustomMock(MagicMock):
def __init__(self):
super().__init__(__something__='something')


mock = CustomMock()
MagicMock(mock)


In Python 3.8 the error is TypeError: __init__() got an unexpected keyword 
argument '_new_parent'. 

In Python 3.9 the error is TypeError: __init__() got an unexpected keyword 
argument 'name'.

STINNER Victor  added the comment:

I "fixed" the issue by skipping broken tests. If anyone wants to fix the 
underlying issue: go ahead and open an issue, it would be way better with a PR 
to fix these tests!

In the meanwhile, skipping broken tests help to detect regressions (new issues).

[issue39530] Documentation about comparisons between numeric types is misleading

2020-02-10 Thread Katherine Michel


Katherine Michel  added the comment:

I'm at the sprints at PyCascades and was looking for an issue to work on and 
came across this and wanted to know more about it. As I was doing some 
research, I found the terms "narrower" and "wider" to seem ambiguous. I'm 
assuming "narrower" to mean that an integer has a more precise value and 
"wider" to mean that a float has a less precise/wider range of possible values, 
but unless I'm missing something, it isn't clear. I think the first paragraph 
should be revised to make the meaning more explicit. Happy to assist (with some 
input), if applicable.

[issue39601] brace escapes are not working in formatted string literal format specifications

2020-02-10 Thread JitterMan



JitterMan  added the comment:

My expectation is that doubling up the braces acts to escape them, meaning that 
characters between the braces is treated as simple text and passed to the 
__format__ method as is. The only processing that should occur on the format 
specification is to convert the double braces to single braces. The fact that 
an error occurs saying that 'v' is not defined before the __format__ method is 
ever called indicates that the contents of the braces are being evaluated as an 
expression, which fails because v is not defined in the outer scope.  Thus the 
f-string seems to be ignoring the escaping of the braces, but it only does so 
in the format specifier.

[issue38324] [Windows] test_locale and test__locale failures on Windows



STINNER Victor  added the comment:

>>> loc=locale.getlocale(locale.LC_CTYPE) 
>>> loc
('tr_TR', 'ISO8859-9')

getlocale() has issues on Unix, but worse issues on Windows. See:

* bpo-12726
* bpo-20087
* bpo-20088
* bpo-23425
* bpo-33934
* bpo-38805

I never use getlocale() and I never understood the purpose of this function. I 
use locale.setlocale(loc) (same than locale.setlocale(loc, None)) to *get* a 
locale: the result can be passed to locale.setlocale(loc, result) with no 
problem.

[issue30155] Add ability to get tzinfo from a datetime instance in C API

2020-02-10 Thread Paul Ganssle

Paul Ganssle added the comment:

So this bug is asking for two things:

1. An official accessor for the `tzinfo` component of an existing datetime,
which I think is very reasonable in light of the fact that there are official
accessors for all the other components of a datetime.

2. An official constructor for a timezone-aware datetime, which I think
basically exists in the form of
PyDatetime_CAPI->PyDateTimeAPI->DateTime_FromDateAndTime /
->DateTime_FromDateAndTimeAndFold, and we just need to document it. I think
this is basically a separate issue, and I have opened #39604 to track it.

I'm going to rename this bug to focus only on issue #1. I think we can accept a
PR adding two new macros. I would suggest calling them:

- PyDateTime_DATE_GET_TZINFO
- PyDateTime_TIME_GET_TZINFO

Please make sure to add tests to any PR you make. See the CapiTest case
(https://github.com/python/cpython/blob/d68e0a8a165761604e820c8cb4f20abc735e717f/Lib/test/datetimetester.py#L5914)
for examples. You may want to look at the git blame for a few of those tests
to see the PRs that they were added in, since part of the tests are defined in
a C file.

(As an aside: I don't love that the accessor methods are not available on the
struct, since all the "macro-only" code needs to be re-implemented in all
other-language bindings. Since the accessors are already all macro-only,
though, might as well keep with the tradition for now :P)

[issue34592] cdll.LoadLibrary allows None as an argument

2020-02-10 Thread Malcolm Smith



Malcolm Smith  added the comment:

This isn't documented, but CDLL(None) is translated to dlopen(NULL), which 
"causes a search for a symbol in the main program, followed by all shared 
libraries loaded at program startup, and then all shared libraries loaded by 
dlopen() with the flag RTLD_GLOBAL" (https://linux.die.net/man/3/dlopen).

This is sometimes useful because it lets you look up a symbol in an 
already-loaded library without needing to give the library's name. For example:

>>> import ctypes
>>> dll = ctypes.CDLL(None)
>>> dll.printf
<_FuncPtr object at 0x7f3427d547c0>
>>> dll.PyObject_Str
<_FuncPtr object at 0x7f3427d54880>

[issue39604] Document PyDateTimeAPI / PyDateTime_CAPI struct

2020-02-10 Thread Paul Ganssle



New submission from Paul Ganssle :

The entire public interface documented for the datetime C API is various C 
macros (see: https://docs.python.org/3/c-api/datetime.html) which are wrappers 
around function calls to the PyDateTimeAPI / PyDatetime_CAPI struct, but the 
struct itself is undocumented. 

Unfortunately (or fortunately, depending on how you think the C API should 
look), pretty much everyone has to know the implementation details of the C API 
struct anyway. Bindings in other languages usually can't use the C preprocessor 
macros and have to directly use the C API struct so projects like PyPy, PyO3 
and Cython are using it. The struct also can do things that the macros can't 
do: consider bug #30155 which is looking for a way to create a datetime object 
with a tzinfo (which is possible using the C struct).

I think we can should go ahead and make the `PyDateTimeAPI` struct "public" and 
document the functions on it. This may be a bit tougher than one would hope 
because the overlap between the macros and the struct functions isn't 100%, but 
it's pretty close, so I would think we'd want to document the two ways to do 
things rather close to one another.

nosy-ing Victor on here in case he has any strong opinions about whether these 
kinds of struct should be exposed as part of the official public interface.

[issue39278] add docstrings to functions in pdb module

2020-02-10 Thread Ognyan Moore



Ognyan Moore  added the comment:

Stumbled across this issue, is there a list of methods/functions that need 
docstrings or should we aim to add docstrings to all methods in pdb.py?

[issue39600] idle_test: test_fontlist_key() fails if two font families have the same name

The test failure comes from our build system where very few fonts are limited. 
For example, you can imagine that only a few variants of Cantarell are 
installed.

Sorry, I forgot to mention that the test failure and the list of strings come 
from two different machines.

The list comes from my laptop where I have many fonts installed.

[issue39600] idle_test: test_fontlist_key() fails if two font families have the same name



STINNER Victor  added the comment:

In LibreOffice, I see 4 flavors of "Cantarell" with different *weight* :

Cantarell
Cantarell Extra Bold
Cantarell Light
Cantarell Thin

whereas tkinter.font.families(frame) returns 4 times the same string: 
"Cantarell". The C function of Tk is TkpGetFontFamilies().

The X11 implementation uses XListFonts() which returns a string like 
"-foundry-family-weight-slant-(...)" but the function only returns the "family" 
substring: it ignores the foundy and the weight for example. So it's not 
surprising to get duplicates. Example: 
"-adobe-helvetica-bold-o-normal--11-80-100-100-p-60-iso8859-1" becomes 
"helvetica".

There is also a Xft implementation which uses XftListFonts(). Then it uses 
XftPatternGetString() to get a font family.

I see no logic in Tcl to exclude duplicated family names of different weights.

--

>>> tkinter.font.names(frame)
('TkCaptionFont', 'TkSmallCaptionFont', 'TkTooltipFont', 'TkFixedFont', 
'TkHeadingFont', 'TkMenuFont', 'TkIconFont', 'TkTextFont', 'TkDefaultFont')

That's something different that I would call unrelated ;-)

[issue39600] idle_test: test_fontlist_key() fails if two font families have the same name



Terry J. Reedy  added the comment:

Serhiy, do you know anything about the tkinter.font.families() tuple having 
duplicate names?  It strikes me as an OS or tk error.

On Windows, the tuple has groups of related names with a base name, such as 
'Segoe UI' both alone and with suffixes, such as 'light', 'black', and 
'symbol'.  I wonder if on Fedora 31 the duplicates are related names with the 
suffixes somehow left off.  Cheryl, do you see any of the above duplicated 
names de-duplicated on Ubuntu with suffixes?

Whether the duplicates are true duplicates, (same family repeated) or mistakes 
(related families missing suffixes), they should be useless to the user.  
Clicking or scrolling through the duplicates should not change the font sample 
as 'Font(family=dupname)' will not change.

Victor, your example does not create a Listbox, so that cannot be the issue.  
The only change to ConfigDialog when testing is that it is not made modal.  
What puzzles me is that test_fontlist_key starts by explicitly activating the 
first font on the list, so that the first test on the Fedora machine should be 
'Android Emoji' != 'Abyssinica SIL'.  Perhaps there is a bug in the tk on that 
machine.

Carol Willing merged the PR before I could review and edit.  I will add a 
follow-up after getting backport to work.
