[issue21925] ResouceWarning sometimes doesn't display

It seems that ResouceWarning about unclosed file handles with '-W all' option

Is this behaviour normal?

[issue20330] PEP 342 is outdated

2014-01-21 Thread Masami HIRATA 

New submission from Masami HIRATA:

Although PEP 342 says foo(yield 42) is legal, Lib/test/test_grammar.py says:
# Requires parentheses as call argument
def g(): f((yield 1))
check_syntax_error(self, def g(): f(yield 1))

BTW, It seems that foo(yield 42) written in ECMAScript 6 is OK.

[issue17708] sys.flags.hash_randomization doesn't return correct value

2013-04-13 Thread Masami HIRATA 

Masami HIRATA added the comment:

It seems there is a misunderstanding on my part.

Python v3.3.1 documentation says,
sys.flags The struct sequence flags exposes the status of command line flags. 
The attributes are read only.

I think that sys.flags.hash_randomization should be always 1 on Python v3.3.1

because the documentation says,
-R 
Kept for compatibility. On Python 3.3 and greater, hash randomization is turned 
on by default.

We should add 'randomization' and 'seed' attribute to sys.hash_info, I think.

[issue16557] PEP 380 isn't reflected in the Functional Programming HOWTO

2012-11-26 Thread Masami HIRATA 

New submission from Masami HIRATA:

Although PEP 380 says:
 2. In a generator, the statement ::
 
 return value
 
 is semantically equivalent to ::
 
 raise StopIteration(value)

Functional Programming HOWTO (Doc/howto/functional.rst) says:
 ``return`` with a value, such as ``return 5``, is a syntax error inside a 
 generator function.

'cp932' is the same as 'mbcs' in the Japanese environment.
