[Python-Dev] Have problem when building python3.5.1 rpm with default SPEC file

2017-01-19 Thread Dahui Jiang 
Hi all:
I'm try to build a python rpm from source python3.5.1, and I use the spec file 
in the source tree.
But the building is not success as print the following error:
***
running build
running build_ext
error: [Errno 2] No such file or directory: 'Modules/Setup'
error: Bad exit status from /var/tmp/rpm-tmp.DDm3jI (%build)


RPM build errors:
Bad exit status from /var/tmp/rpm-tmp.DDm3jI (%build)


Regards
Dahui

Hello,

This is a distro specific issue so this list might not be the best for 
resolving that, you should contact your distro's package maintainers of python.

For Fedora 25 we currently ship Python 3.5.2, which builds fine with this SPEC 
file [0], so maybe you could give this a try.

[Python-Dev] FunctionDef.returns - explicit 'None' return type hint

2017-01-19 Thread Valentin Iovene via Python-Dev 
With a ast.FunctionDef ast.AST node, is it possible to make the
difference between this function

def hello_world():
print('hello world')

and this one

def hello_world() -> None:
print('hello world')

?

In both cases, the FunctionDef node has its 'returns' (return type
hint) attribute set to None.

>>> t = compile('def f(): pass', '', 'exec', ast.PyCF_ONLY_AST)
>>> print(t.body[0].returns)
None
>>> t = compile('def f() -> None: pass', '', 'exec', ast.PyCF_ONLY_AST)
>>> print(t.body[0].returns)

>>>  print(t.body[0].returns.value)
