[issue32758] Stack overflow when parse long expression to AST

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

A consequence of this is that ast.literal_eval() can crash.

>>> import ast
>>> ast.literal_eval("+0"*20)
Segmentation fault (core dumped)

It should be documented that ast.literal_eval() is not safe.

[issue32893] ast.literal_eval() shouldn't accept booleans as numbers in AST

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

The definition of "Python literal structures" is not specified, but it is 
implied that ast.literal_eval() should accept signed numbers and 
tuple/list/set/dict displays consisting of "Python literal structures".

ast.literal_eval() accepts unary minus for supporting negative numbers. In 
Python 2 "-42" was parsed as a single AST node Num(42), but in Python 3 it is 
parsed as UnaryOp(USub(), Num(42)). ast.literal_eval() accepts binary plus and 
minus for supporting complex numbers (there are oddities in this). The support 
of unary plus was added somewhere for unknown reason (see 884c71cd8dc6, no 
issue number), but it doesn't harm.

Below in the documentation: "It is not capable of evaluating arbitrarily 
complex expressions, for example involving operators or indexing." Arbitrarily 
complex expressions involving addition and subtraction (like "2017-10-10") was 
supported in Python 3 (but not in Python 2), but it was fixed in 3.7 (see 
issue31778). It doesn't support other operations or operations with non-numeric 
literals. It is oversight that UnaryOp(USub(), Constant(True)) is still 
accepted.

[issue32820] Add __format__ method to ipaddress

[Nick Coghlan]

Nick Coghlan  added the comment:

I think supporting "s" makes sense, as we're going to need to treat the empty 
format string as implying "s" for backwards compatibility reasons:

>>> f"{v4}"
'1.2.3.4'

Right now, attempting to format that field without `!s` will give you a 
TypeError, but as Eric O notes, once IP addresses support __format__, we're 
going to have to choose between:

- raise an exception if formatting directions are given without a numeric 
typecode
- ignore the formatting in that case (which is what the current PR does)
- handle it the same way "!s" would (and also allow "s" as an explicit type 
code)

The last option sounds the most desirable to me, as that way we can just say 
"'s' is the default IP addressing formatting typecode" (similar to the way 'd' 
is the default for integers, and 'g' is the default for floating point numbers).

I *don't* think we should allow combining the numeric typecode with the string 
type code, though. The numeric types don't allow that, and f-strings already 
support nesting if you want to combine string formatting with numeric 
formatting:

>>> f"{f'{42**100:g}':>20s}"
'2.11314e+162'

[issue32931] Python 3.70b1 specifies non-existent compiler gcc++

[Marc Culler]

New submission from Marc Culler :

Compiling an external module in the 3.7.0b1 prerelease on macOS High Sierra 
failed for me because a compiler named "gcc++" was not found.  As far as I can 
tell there is no such compiler in the current XCode release.  I don't know if 
there ever was one.  The culprit file is:

/Library/Frameworks/Python.framework//Versions/3.7/lib/python3.7/_sysconfigdata_m_darwin_darwin.py

The following patch fixed the problem for me:

38c38
<  'CXX': 'gcc++',
---
>  'CXX': 'g++',
484c484
<  'LDCXXSHARED': 'gcc++ -bundle -undefined dynamic_lookup',

[issue28134] socket.socket(fileno=fd) does not work as documented

[YoSTEALTH]

YoSTEALTH  added the comment:

Christian thank you for your reply, i really appreciate it.

Lets analyze this a bit:
- Technically speaking i can "return client" directly and it would NOT close 
the socket.
- Shouldn't "inside" having reference to same fd mean +1 to reference count. 
Considering its a new object?
id(client): 140340037397192
id(inside): 140340010863560

I could understand making a duplicate of the fd if it were being passed across 
thread/process but in its original thread making a duplicate! This behavior is 
extremely odd.

I fell like everyone that uses socket(fileno) will run into days wasted and 
frustration just to figure out these solutions.

[issue32930] [help][webbrowser always opens new tab. I want to open in the same tab]

[Tommy]

New submission from Tommy :

Dear manager,

I'm just starting python and trying to make simple web application.
As above title, I just want to open webbrowser at first and then just change 
web-address in the same tab, but whenever I try webbrowser.open, it always open 
new tab or new window.
When I checked webbrowser-control options on python help page, it says 
webbrowser.open's 2nd argument can control window opening. but it did not work 
well in my tries. following is my test code.

#1st try
import webbrowser
url = 'www.google.com'
webbrowser.open(url, new=0) # this open new explorer window.

#wait

#2nd try
webbrowser.open(url, new=0) # this open new explorer window again.

In my test, I test 2nd argument from 0 to 2, but there seems no change.
always opens new tab.

Is there any way to change address and open in the current opened browser 
window?

best Regards,
Tommy

[issue32893] ast.literal_eval() shouldn't accept booleans as numbers in AST

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Whoops, my previous response was wrong as written because I wrongly thought 
that if literal_eval accepts number_literal + imaginary_literal, it would also 
accept number_literal + number_literal. I am replacing it with the following.

The ast.literal_eval doc says 
"The string or node provided may only consist of the following Python literal 
structures: strings, bytes, numbers, tuples, lists, dicts, sets, booleans, and 
None."

Since 'True', '(True,)', '[True]', '{True:True}', '+1', '-1' and '1+1j' are 
accepted as 'literal structures', it seems arbitrary that at least '+True' and 
'True+1j' are not.  ('+1', '1+1j' and especially '-1' seem to violate the 
limitations to 'literal', 'container', and 'no operator', but that is a 
different issue.)

I strongly agree that the acceptable string inputs and acceptable AST inputs 
should match.  The question is which version of the domain should be changed.  
I would at least mildly prefer that the issue be "ast.literal_eval should 
consistly treat False and True the same as 0 and 1.", which means expanding the 
string version.  As Raymond said, this is the general rule in Python.  What is 
the benefit of having a different rule for this one function?

[issue32929] Change dataclasses hashing to use unsafe_hash boolean (default to False)

[Eric V. Smith]

New submission from Eric V. Smith :

See https://mail.python.org/pipermail/python-dev/2018-February/152150.html for 
a discussion.

This will remove the @dataclass hash= tri-state parameter, and replace it with 
an unsafe_hash= boolean-only parameter.

>From that thread:

"""
I propose that with @dataclass(unsafe_hash=False) (the default), a __hash__
method is added when the following conditions are true:

- frozen=True (not the default)
- compare=True (the default)
- no __hash__ method is defined in the class

If we instead use @dataclass(unsafe_hash=True), a __hash__ will be added
regardless of the other flags, but if a __hash__ method is present, an
exception is raised.

Other values (e.g. unsafe_hash=None) are illegal for this flag.

[issue28134] socket.socket(fileno=fd) does not work as documented

[Christian Heimes]

Christian Heimes  added the comment:

The problem is fixed and your example behaves as expected.

The laddr string is the result of inside.getsockname() and raddr string is the 
result of inside.getpeername(). In your example, inside and client share the 
same file descriptor. When the function exits client goes out of scope, the 
reference count of client drops to 0, the object gets deallocated and Python 
closes the shared file descriptor. In outside, the shared fd is gone and 
outside.getsockname() and outside.getpeername() fail. Basically the outside 
socket is dead because its fd has been closed.

You have to duplicate the fd or detach the socket to keep the fd open.

[issue32893] ast.literal_eval() shouldn't accept booleans as numbers in AST

[Terry J. Reedy]

Terry J. Reedy  added the comment:

It is true that 'True' and 'False' are not literally literals.  But as pre- and 
fixedly bound names, they function for Bool the same as 0 and 1 do for int.

Besides this, ast.literal_eval is not now limited to literal evaluation, but 
does compile-time computation of some constant expressions, in particular even 
nested tuples like '(1, (2, (3, (4,5' or '(False, (True, False))' and even 
some expressions yielding mutable objects, like '[1,2]' (see below).  
'safe_eval' might be a better name now.

The benefit of compressing 'True+True' to 2 at compile time is the same as 
compressing '1+1' to 2. Given what literal_eval actually is now, it is 
surprising and to me confusing that this is rejected, while a tuple with 
booleans is accepted (as it should be!).  It is also a bug relative to the doc:

"The string or node provided may only consist of the following Python literal 
structures: strings, bytes, numbers, tuples, lists, dicts, sets, *booleans*, 
and None." [*s added]

So I think this issue should be flipped to "ast.literal_eval should 
consistently accept False and True" and marked as a bugfix.

I am using 3.7.0b1 i don't think this issue is fixed!

# simple mockup:
# --
def accept(sock):
client, addr = sock.accept()
inside = socket(fileno=client.fileno())
print(inside)
# <__main__.Socket fd=5, family=AddressFamily.AF_INET, 
type=SocketKind.SOCK_STREAM, proto=6, laddr=('127.0.0.1', 8000), 
raddr=('127.0.0.1', 42532)>
return inside

outside = accept(sock)
print(outside)
# <__main__.Socket fd=5, family=AddressFamily.AF_INET, 
type=SocketKind.SOCK_STREAM, proto=6>


So the "laddr" and "raddr" goes missing the second its out of the function???

This has wasted days of my time, to even get to this point of figuring out 
whats going on wasn't easy! extremely frustrating.

[issue32875] Add __exit__() method to event loops

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Enhancements only go in future releases not yet in beta.

Do loops already have an __enter__ method, also required for with?  What would 
you have the close method do?  Preemptorially cancel all tasks and close the 
loop?  With statement are usually for ensuring deterministic cleanup after the 
last substatement, such as closing a file.  Can you give a short usage example?

[issue32867] argparse assertion failure with multiline metavars

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I don't understand the -h (display help part) but pasting code into repository 
3.8 IDLE editor and running, I get same traceback.

Never having used argparse, I don't know if a multiline metavar is expected to 
work.  Assuming so, can you suggest a fix?

[issue32927] Add typeshed documentation for unittest.TestCase._feedErrorsToResult and ._outcome

[Victor Engmark]

New submission from Victor Engmark :

Until and unless #32926 is fixed it would be good to be able to type inspect 
code which uses the currently least hacky way to inspect the result of the 
current test [1]. This requires the use of TestCase._feedErrorsToResult and 
TestCase._outcome.

[issue32926] Add public TestCase method/property to get result of current test

[Victor Engmark]

New submission from Victor Engmark :

The community has come up with multiple hacks [1] to be able to inspect the 
current test result in tearDown (to collect more expensive diagnostics only 
when the test fails). It would be great to have a documented and simple way to 
check whether the test currently in play was successful. To be clear, 
TestCase.wasSuccessful() is not useful in this case, since it only reports 
whether all tests run so far were successful.

[issue32925] AST optimizer: Change a list into tuple in iterations and containment tests

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

Currently a list of constants is replaced with constant tuple in `x in [1, 2]` 
and `for x in [1, 2]`. The resulted AST is the same as for `x in (1, 2)` and 
`for x in (1, 2)`.

The proposed simple PR extends this optimization to lists containing 
non-constants. `x in [a, b]` will be changed into `x in (a, b)` and `for x in 
[a, b]` will be changed into `for x in (a, b)`. Since creating a tuple is 
faster than creating a list the latter form is a tiny bit faster.

$ ./python -m timeit -s 'a, b = 1, 2' -- 'for x in [a, b]: pass'
500 loops, best of 5: 93.6 nsec per loop

$ ./python -m timeit -s 'a, b = 1, 2' -- 'for x in (a, b): pass'
500 loops, best of 5: 74.3 nsec per loop

./python -m timeit -s 'a, b = 1, 2' -- '1 in [a, b]'
500 loops, best of 5: 58.9 nsec per loop

$ ./python -m timeit -s 'a, b = 1, 2' -- '1 in (a, b)'
1000 loops, best of 5: 39.3 nsec per loop

[issue32820] Add __format__ method to ipaddress

[Eric Osborne]

Eric Osborne  added the comment:

I dunno, I think this might be useful.  A binary representation is itself a
string, and takes formatting as such (ditto for hex, as hex(int()) returns
a string:

In [20]: a
Out[20]: IPv4Address('1.2.3.4')

In [92]: f'{a}'
Out[92]: '1.2.3.4'

In [21]: int(a)
Out[21]: 16909060

In [22]: f'{bin(int(a)):42s}'
Out[22]: '0b1001000110100   '

In [24]: f'{a:b}'
Out[24]: '0001001000110100'

In [25]: f'{a:b42s}'
Out[25]: '1.2.3.4'

That last one should return '1001000110100'.  I was
worried about going down a really deep rabbit hole trying to support a lot
of string format stuff with no use case, but there's not much more which
could be done which makes any sense.  's' seems reasonable.

My current code supports [b, x, n] integer presentation types.  I need to
add [X], that's just an oversight.  Supporting [b, x, X, n] means that an
IP address is considered an integer, and should get the subset of integer
presentations which make sense. Not the full set - neither octal nor
character are good fits.  But support for some sort of alignment padding
seems reasonable.  Consider:

In [61]: f'{42:30}'
Out[61]: '42'

In [62]: f'{int(a):30}'
Out[62]: '  16909060'

In [63]: f'{a:30}'
Out[63]: '1.2.3.4'

In [66]: f'{a:42b}'
Out[66]: '0001001000110100'

Those last two seem odd.  I think f'{a:30}' should return the same thing as
this:

In [69]: f'{str(a):30}'
Out[69]: '1.2.3.4   '

and f'{a:42b'} should return the same thing as this:

In [77]: f'{bin(int(a)):42}'
Out[77]: '0b1001000110100   '

This also means supporting [>,<,^] alignment.  And, of course, ignoring any
length spec too short, as is done with regular integer formatting:

In [86]: b
Out[86]: 16909060

In [87]: f'{b:6}'
Out[87]: '16909060'

Thoughts?

[issue32915] Running Python 2 with -3 flag doesn't complain about cmp/__cmp__

[Raymond Hettinger]

Raymond Hettinger  added the comment:

The stated goal of -3 is "warn about Python 3.x incompatibilities that 2to3 
cannot trivially fix", so this use case seems like a good match.

On the other hand, adding this to -3 would be somewhat noisy since __cmp__ is 
pervasive in 2.7.

I'm willing to give it another go. Do you want to open a PR to turn it back on

[issue25427] Remove the pyvenv script in Python 3.8

[Brett Cannon]

Brett Cannon  added the comment:

Oh, I haven't forgotten. :) This issue is the only one I have assigned to 
myself and been looking forward to ripping it out for over 2 years (might not 
get to it until the sprints at PyCon US, but I will definitely be ripping it 
out).

[issue32924] Python 3.7 docs in docs.p.o points to GitHub's master branch

[Mariatta Wijaya]

New submission from Mariatta Wijaya :

When viewing Python 3.7 docs in docs.python.org, the show source link is 
pointing to the master branch on GitHub. It should point to the 3.7 branch.

I'm working on a fix, however this is something to we should remember doing 
when we go to 3.9+. 

Adding Python 3.8 and 3.9's release manager :)

[issue32923] Typo in documentation of unittest: whilst instead of while

[Mariatta Wijaya]

Mariatta Wijaya  added the comment:

`while` and `whilst` are both valid english words, however I can understand if 
readers who don't primarily speak english can get confused.

I'll be open to change that to `while` just to make it friendlier to 
international readers.

[Steve Dower]

Steve Dower  added the comment:

The sources are just the original sources, so they could be useful on other 
platforms too.

The build on cpython-bin-deps is obviously only useful on Windows.

[issue32923] Typo in documentation of unittest: whilst instead of while

[Тимофей Хирьянов]

New submission from Тимофей Хирьянов :

Typo is on the https://docs.python.org/3/library/unittest.html page.

At bottom of the page you can see text: "unittest.removeHandler(function=None)
When called without arguments this function removes the control-c handler if it 
has been installed. This function can also be used as a test decorator to 
temporarily remove the handler whilst the test is being executed:"

Typo is: ST instead of E in the word "whilst".

New submission from Josh Friend :

Armin Rigo from the PyPy project pointed this out to me: 
https://bitbucket.org/pypy/pypy/issues/2755/dbmopen-expects-a-str-for-filename-throws

This could probably lead to some weird behavior given the right filename
