[issue35107] untokenize() fails on tokenize output when a newline is missing

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

I am surprised, that removing the newline character adds a token:

>>> pprint.pprint(list(tokenize.generate_tokens(io.StringIO('#\n').readline)))
[TokenInfo(type=55 (COMMENT), string='#', start=(1, 0), end=(1, 1), line='#\n'),
 TokenInfo(type=56 (NL), string='\n', start=(1, 1), end=(1, 2), line='#\n'),
 TokenInfo(type=0 (ENDMARKER), string='', start=(2, 0), end=(2, 0), line='')]
>>> pprint.pprint(list(tokenize.generate_tokens(io.StringIO('#').readline)))
[TokenInfo(type=55 (COMMENT), string='#', start=(1, 0), end=(1, 1), line='#'),
 TokenInfo(type=56 (NL), string='', start=(1, 1), end=(1, 1), line='#'),

[issue35108] inspect.getmembers passes exceptions from object's properties through

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

Sorry I misread your title stating it's about object getattr for a property has 
to execute the underlying code it seems as explained in 
https://stackoverflow.com/a/30143990/2610955 . I don't know if there is a way 
through which an attribute access in case of property can be verified without 
executing it. In case of catching the exception and returning the attributes 
that don't raise exception since it depends on the runtime execution of the 
property where the exception might occur at one point in time and doesn't occur 
in another point of time causing confusion during debugging.

[issue32972] unittest.TestCase coroutine support

[Dave Shawley]

Dave Shawley  added the comment:

Hi all, I took a slightly different direction for adding async/await support to 
the unittest library.  I summarized the approach that I took in a message to 
python-ideas 
(https://mail.python.org/pipermail/python-ideas/2018-October/054331.html) and a 
branch is available for preview in my fork of cpython 
(https://github.com/dave-shawley/cpython/pull/1).

My question is whether I should reboot this bpo with my PR or create a new one 
since the implementation is different than what was already discussed?

[issue35081] Rename Include/internals/ to Include/pycore/

[STINNER Victor]

STINNER Victor  added the comment:

My changes move Py_BUILD_CORE to Include/internal/. I'm not sure of the effect 
on the backward compatibility.

Since Python 3.7, many "Py_BUILD_CORE" functions rely on Include/internal/, 
like PyThreadState_GET() which uses _PyRuntime.gilstate.tstate_current.

On my Fedora 28, the python3-devel package doesn't proide Include/internal/ 
headers, only Include/*.h in /usr/include/python3.7m/. It seems like 
Include/internal/ is not usable by 3rd party modules on Fedora at least.

I understand that even if a 3rd party C extension used the Py_BUILD_CORE API, 
Python 3.7 already broke these extensions.

I don't want C extensions to use Py_BUILD_CORE: Py_BUILD_CORE API is really 
designed to only be used inside Python. If this API is used outside Python, we 
cannot modify the API anymore since it would break extensions. But I want to 
make sure that we can break this API for different reasons.

In Python 3.7, pyatomic.h is included by Python.h. In Python 3.7.0, pyatomic.h 
content wasn't surrounded by Py_BUILD_CORE and this header file caused multiple 
compilation issues: see bpo-23644 and bpo-25150. The content is now restricted 
to Py_BUILD_CORE since Python 3.7.1. It allows us to more easily change the 
implementation.

[issue35115] UUID objects can't be casted by `hex()`

[fcurella]

New submission from fcurella :

Casting a UUID to an `int` or to a string works as expected:

```
import uuid

value = uuid.UUID()
str(value)
int(value)
```

but casting to an `hex()` raises an exception:

```
import uuid

value = uuid.UUID()

# uuid instances already have the correct value stored in the `.hex` attribute
value.hex

# this raises `TypeError: 'UUID' object cannot be interpreted as an integer`
hex(value)

# this behaves correctly
hex(value.int)

```

Adding support for `hex()` should be simple enough as adding the following to 
the UUID class in 
https://github.com/python/cpython/blob/54752533b2ed1c898ffe5ec2e795c6910ee46a39/Lib/uuid.py#L69:

```
def __index__(self):
return self.int
```

[issue26175] Fully implement IOBase abstract on SpooledTemporaryFile

[nubirstein]

nubirstein  added the comment:

My last comment meant to land somewhere else, but nonetheless it is related to 
this topic, so:

SpooledTemporaryFile class from lib/tempfile.py still does not implement 
seekable() method. It could be like this (just two lines of code and my 
Flask.Request tests with sending files started again to work on 3.7:

def seekable(self):
return self._file.seekable()

Is it possible to add this method?

[issue35114] ssl.RAND_status docs describe it as returning True/False; actually returns 1/0

[Josh Rosenberg]

New submission from Josh Rosenberg :

The ssl.RAND_status online docs say (with code format on True/False):

"Return True if the SSL pseudo-random number generator has been seeded with 
‘enough’ randomness, and False otherwise."

This is incorrect; the function actually returns 1 or 0 (and the docstring 
agrees).

Fix can be one of:

1. Update docs to be less specific about the return type (use true/false, not 
True/False)
2. Update docs to match docstring (which specifically says 1/0, not True/False)
3. Update implementation and docstring to actually return True/False (replacing 
PyLong_FromLong with PyBool_FromLong and changing docstring to use True/False 
to match online docs)

#3 involves a small amount of code churn, but it also means we're not 
needlessly replicating a C API's use of int return values when the function is 
logically bool (there is no error status for the C API AFAICT, so it's not like 
returning int gains us anything on flexibility). bool would be mathematically 
equivalent to the original 1/0 return value in the rare cases someone uses it 
mathematically.

[issue35113] inspect.getsource returns incorrect source for classes when class definition is part of multiline strings

[Karthikeyan Singaravelan]

New submission from Karthikeyan Singaravelan :

inspect.getsource uses inspect.findsource that uses a regex to check for class 
declaration and starts matching against the regex from the start of the 
program. When there is a match it checks for the first character to be 'c' to 
return the line number from which getblock is used to get the class definition. 
If there are multiple matches and there is no line with 'c' as the first 
character in the line then they are sorted based on the number of whitespaces 
preceding class keyword. This poses the following problem :

1. When a class definition like string occurs as part of a multiline string 
before the actual definition then this causes the function to return the 
multiline string instead of actual definition. This occurs both while using the 
multiline string also as comment and also using them in variable definition in 
other places.

2. When the class is defined inside another class and there is a similar 
multiline string inside another class which is indented along the same 
indentation level of the class then they are sorted by whitespace where they 
are equal and then followed by line number. Since the class definition occurs 
after the multiline string it causes the multiline string to be taken up as the 
source of the class.

This was last changed in 89f507fe8c4 (Dec 2006) which is also a merge commit. I 
searched for issues and relevant test cases but I couldn't find any in the test 
suite or issue tracker regarding the same. Hence I am filing a new issue.

[issue35112] SpooledTemporaryFile and seekable() method

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

The related issue already implements seekable and other methods for IOBase. As 
I can see from the open PR there are PR comments with respect to tests and docs 
that need to be acted upon as per reviewer's comments. With respect to this 
issue I propose closing this as a duplicate with issue26175 as superseder to 
continue your discussion there where it might be useful. 

Thanks!

[issue19376] document that strptime() does not support the Feb 29 if the format does not contain the year

[Paul Ganssle]

Paul Ganssle  added the comment:

@Victor: You mean a PR to fix the *issue* or a PR to add this to the docs?

The current behavior is pretty counter-intuitive, particularly because it also 
fails because of the (relatively) little-known fact that 1900 happens to not be 
a leap year because it is evenly divisible by 100 but not by 400.

I think it's pretty simple for end-users to work around this:

def strptime_smarter(dtstr, fmt):
try:
return datetime.strptime(dtstr, fmt)
except ValueError:
tt = time.strptime(dtstr, fmt)
if tt[0:3] == (1900, 2, 29):
return datetime(1904, *tt[1:6])
raise


But this is largely a problem that arises because we don't have any concept of 
a "partial datetime", see this dateutil issue: 
https://github.com/dateutil/dateutil/issues/449

What users want when they do `datetime.strptime("Feb 29", "%b %d")` is 
something like `(None, 2, 29)`, but we're both specifying an arbitrary default 
year *and* enforcing that the final date be legal. I think the best solution 
would be to change the default year to 2000 for *all* dates, but for historical 
reasons that is just not feasible. :(

Another option is that we could allow specifying a "default date" from which 
missing values would be drawn. We have done this in dateutil.parser.parse: 
https://dateutil.readthedocs.io/en/stable/parser.html#dateutil.parser.parse

The biggest problem in dateutil is that the default value for "default date" is 
the *current date*, which causes many problems with reproducibility. For 
`datetime.strptime`, the default value would be `datetime(1900, 1, 1)`, which 
has none of those same problems.

Still, adding such a parameter to `datetime.strptime` seems like a lot of 
effort to go through to just to make it *easier* for people to work around this 
bug in `strptime`, particularly since in this case you can *kinda* do the same 
thing with:

strptime('1904 ' + dtstr, '%Y %b %d')

Long-winded carping on about datetime issues aside, I think my final vote is 
for leaving the behavior as-is and documenting it. Looking at the 
documentation, the only documentation I see for what happens when you don't 
have %Y, %m or %d is:

For time objects, the format codes for year, month, and day should not be 
used,
as time objects have no such values. If they’re used anyway, 1900 is 
substituted
for the year, and 1 for the month and day.

This only makes sense in the context of `strftime`. I think for starters we 
should document the behavior of strptime when no year, month or day are 
specified. As part of that documentation, we can add a footnote about Feb 29th.

I can make a PR for this, but as Tal mentions, I think this is a good issue for 
a first-time contributor, so I'd like to give someone else an opportunity to 
take a crack at this.

[issue35107] untokenize() fails on tokenize output when a newline is missing

[Terry J. Reedy]

Terry J. Reedy  added the comment:

It seems to me a bug that if '\n' is not present, tokenize adds both NL and 
NEWLINE tokens, instead of just one of them.  Moreover, both tuples of the 
double correction look wrong.

If '\n' is present,
  TokenInfo(type=56 (NL), string='\n', start=(1, 1), end=(1, 2), line='#\n')
looks correct.

If NL represents a real character, the length 0 string='' in the generated
  TokenInfo(type=56 (NL), string='', start=(1, 1), end=(1, 1), line='#'),
seems wrong.  I suspect that the idea was to mis-represent NL to avoid '\n' 
being added by untokenize.  In
  TokenInfo(type=4 (NEWLINE), string='', start=(1, 1), end=(1, 2), line='')
string='' is mismatched by length = 2-1 = 1.  I am inclined to think that the 
following would be the correct added token, which should untokenize correctly
  TokenInfo(type=4 (NEWLINE), string='', start=(1, 1), end=(1, 1), line='')

ast.dump(ast.parse(s)) returns 'Module(body=[])' for both versions of 's', so 
no help there.

[issue35115] UUID objects can't be casted by `hex()`

[fcurella]

fcurella  added the comment:

I must admit I was surprised to find out that `hex()` uses `__index__` (which 
is supposed to return an integer) and not something like a `__hex__` method 
returning the hex.

Maybe we should change the behaviour of `hex()` instead? (in a 
backward-compatible way, of course)

IMHO implementing "__index__" for UUID would not the correct solution. That 
method is meant be used by integer-like objects. One of the side effects of 
implementing "__index__" is that indexing lists with UUID instances would start 
to work, which is IMHO not correct.

it works in Python 3 but not 2, and this effects behaviour and performance...

[issue35115] UUID objects can't be casted by `hex()`

[Mark Dickinson]

Mark Dickinson  added the comment:

Agreed that UUID should not implement `__index__`. I wouldn't expect to be able 
to use a UUID as a list index, for example.

This is marked as "behavior", but I have a hard time seeing this as a bug. It's 
not even a usability bug, given how easy it is to get the hex value of a UUID 
with `.hex`.

Maybe the UUID class should grow a `__format__` implementation that respects 
the `x` format specifier?

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Note that str() for UUIDs already returns the hexadecimal representation, just 
with minuses.

I don't see large usability difference between 'uuid={:x}'.format(u) and 
'uuid={.hex}'.format(u). And in many case 'uuid={}'.format(u) is appropriate as 
well.

[issue35081] Rename Include/internals/ to Include/pycore/

[STINNER Victor]

STINNER Victor  added the comment:

Include/internal/pystate.h uses #include "pystate.h" to include 
Include/pystate.h, but it tries to include itself (Include/internal/pystate.h) 
which does nothing because of "#ifndef Py_INTERNAL_PYSTATE_H #define 
Py_INTERNAL_PYSTATE_H ... #endif".

Remove the #ifndef #define to see the bug:

[issue35109] Doctest in CI uses python binary built from master causing DeprecationWarnings

I agree with the same. Maybe I am running doctest wrong locally? I use make 
venv and make doctest. Sorry for the confusion on this.

[issue35109] Doctest in CI uses python binary built from master causing DeprecationWarnings

[Julien Palard]

Julien Palard  added the comment:

> Maybe I am running doctest wrong locally?

Dunno. IIRC we had problems running doctest with a Python 3.7 on the 3.8 
branch, which make sense.

Anyway, if it works today, the first developper writing doctest about a 3.8 
feature will cause a doctest failure so no we can't use 3.7 to test 3.8.

[STINNER Victor]

STINNER Victor  added the comment:

I suggest to not add the new parameter to 3.4 and 3.5 branches, even if it's a 
security fix. The fix requires to *use* the parameter, and I don't expect 
applications on Python 3.4 and 3.5 to be modified to use it.

[issue35034] Add closing and iteration to threading.Queue

[Vladimir Filipović]

Vladimir Filipović  added the comment:

Hi Raymond!

I've posted to python-ideas: 
https://mail.python.org/pipermail/python-ideas/2018-October/054238.html

The amount of attention it got was modest, so I couldn't exactly say the 
community has thoroughly vetted and enthusiastically endorsed this proposal :)

But all responses were in the narrow range of neutral to MILDLY positive.
There weren't any objections at all to either the idea or the code. Nor did 
anybody question whether a feature of this kind should be added at all.

I don't think I could realistically expect much more support than that for a 
change this minor. (Well, it would have been better if at least one person'd 
had an (uncontested) strongly positive response.)

Some problems with other kinds of implementations were brought up, but this one 
isn't vulnerable to them. I believe I've also addressed all your comments from 
this BPO issue in the opening post there.

An older discussion was linked, which had also shown tacit consensus that this 
type of feature in general would be welcome.

I suppose it's time to decide if that level of response is enough.

[issue35109] Doctest in CI uses python binary built from master causing DeprecationWarnings

[Julien Palard]

Julien Palard  added the comment:

> I propose using stable version of Python like python 3.7

If we do so, we won't be able to write doctest about new features (existing in 
3.8, not existing in 3.7), which is worse than having warnings.

I think the right move is to do some PR on remote projects (like babel) to fix 
the warning, future-proofing them from having a real issue in 3.8.

[issue35109] Doctest in CI uses python binary built from master causing DeprecationWarnings

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

I have an open PR for babel https://github.com/python-babel/babel/pull/608 . 
The problem is merging them and cutting a new release depends on the 
maintainers availability. Once it's fixed we have to make sure dependencies of 
babel like sphinx use the latest version and also make a release if needed. I 
agree it has to be fixed on those projects but coordinating release across 
various projects depends on the maintainers availability and shouldn't end up 
as a blocker for CPython's development here and in future with these type of 
deprecation warnings. I suggested using a stable version because when ran 
locally make venv for doctest uses python3 as binary name and on CI it uses 
python built from master branch that might cause confusion. Also it's not 
necessarily CPython's responsibility to make sure all our external projects 
work well on development branch.

We can keep this as an open issue while the warnings are fixed in the projects 
and also use this for reference when the collections import related code has to 
be removed.

Agreed that we need to run on the master branch binary for 3.8 only features 
like PEP 572 which is a language level change. Sorry, I forgot about that 
scenario. I guess it's then the right way to fix the dependencies upstream so 
that they work properly on development branch going forward.

[issue35117] set.discard should return True or False based on if element existed.

[Windson Yang]

Windson Yang  added the comment:

I guess we can implement using ref_count? However, I agreed 

"The use of variables that haven't been defined or set (implicitly or 
explicitly) is almost always a bad thing in any language since it indicates 
that the logic of the program hasn't been thought through properly, and is 
likely to result in unpredictable behavior."
