[Python-Dev] [RELEASE] Python 3.4.2 is now available

2014-10-08 Thread Larry Hastings 



On behalf of the Python development community and the Python 3.4 release 
team, I'm pleased to announce the availability of Python 3.4.2. Python 
3.4.2 has many bugfixes and other small improvements over 3.4.1.  One 
new feature for Mac OS X users: the OS X installers are now distributed 
as signed installer package files compatible with the OS X Gatekeeper 
security feature.


You can download it here:

   https://www.python.org/download/releases/3.4.2


May the road rise up to meet you,

[Python-Dev] shebang policy, and pip

2014-10-08 Thread Christian Tismer 

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA512

Howdy,

this question is a bit about general policy which is not yet
covered in the python recommendations:

I see projects which do check-ins like "get rid of shebang lines"
and they remove those lines from non-script sources.

It is not always clear to me what to do, so I tend to leave those
lines in per default, in order not to waste time thinking about it,
but well, today I was confronted with that.

Digging a bit deeper shows the following:

python docs:
No mention of shebang, but for Windows.
https://docs.python.org/3/search.html?q=shebang&check_keywords=yes&area=default
https://docs.python.org/3/using/windows.html?highlight=shebang

Google's python style guide also says when a shebang is needed, but
does not forbid it.

Pep 394 explains how to use shebang, but still nothing about not using it.
http://legacy.python.org/dev/peps/pep-0394/

So is there anything officially preferred, and should that go into pep 8?


Special case with pip
- --

I was looking through my installed packages and wondered quite
much about pip:

Pip has a shebang in the __init__ file, but no shebang in the
__main__ file.

I guess this is wrong and should be in the executable file,
which is __main__ .

cheers - Chris

This page  redirect me to
https://www.python.org/download/releases/3.4.1 Maybe some web servers
of the CDN don't contain the latest version. I guess that the issue
will quickly disappears.

Further if you navigate from 3.4.1 to 3.4.2 it says "Python 3.4.2rc1 was 
released on October 8th, 2014.".  The download itself is correct.


Thanks as always to everybody who has contributed, another great piece 
of work.

Some editors can use shebang lines to control syntax highlighting or linting
(mine for example will lint different for python2 vs python3 shebangs).

*puts on pip developer hat*

I’m guessing that comes from when pip used to be a single file and from before
we dropped support for Pythons that didn’t support python -m. It’s probably
nonsense cruft that’s just been left over and hadn’t been managed to be deleted
now.

2014-10-08 Thread Geoffrey Spear 
It looks like the Download dropdown on python.org has a blank button
(when accessed from Windows) has an empty button that's supposed to be
for the 3.4.2 release by just links back to the current page; the 2.7
button is working fine.

Sure. Though it doesn’t resolve it to determine what that would actually 
execute,
it just uses the name of the python in the shebang as heuristics.

Interesting use case, of course! At first sight, at least ;-)

But it becomes relatively awkward when virtualenv is used:
There is no textual distinction between python 2 and 3, and
the text editor would have to do more analysis to get things
right than to guess from the shebang line.

Which then makes it useless, and the editor would need to grab
the real python interpreter to find things out.

Does it support shebang lines like:

#!/usr/bin/env python

Some editors can also use `# -*- foo -*-` comments to set up editing modes and
there are other ways to specify which version linters to use.

I generally avoid shebangs where they aren't needed, and between entry points
and -m they rarely are these days.  I find most uses are in smaller one-off
scripts and such.
