Re: [Python-Dev] Speeding up CPython 5-10%

2016-05-17 Thread zreed
In the project https://github.com/zachariahreed/byteasm I mentioned on
the list earlier this month, I have a pass that to computes stack usage
for a given sequence of bytecodes. It seems to be a fair bit more
agressive than cpython. Maybe it's more generally useful. It's pure
python rather than C though.

[Python-Dev] Python2.7.11+ as in Debian testing and Ubuntu 16.04 LTS crashes with segfault

2016-05-17 Thread Dr . Ján Jockusch
Hello Python Developers,

I would like to draw your attention to a segmentation fault bug which
concerns the packaged versions of Python 2.7.11 as seen in Ubuntu's
latest 16.04 release and in Debian testing.


I have reported this bug in Ubuntu's tracker here:

https://bugs.launchpad.net/ubuntu/+source/python2.7/+bug/1580577


The report contains a script which can reproduce the error for both
distributions' python2.7 packages.

The plain python.org version 2.7.11 does not exhibit this problem.



Matthias Klose, Debian maintainer for the package, has asked me to
report this problem upstream, because otherwise we will invariably run
into this regression in 2.7.12.

I'd like to help in tracking down this bug, please advise.


Thank you,

- Ján Jockusch

Please file the bug on bugs.python.org so we don't lose track of this.

[Python-Dev] Python 3.6.0a1 is now available

2016-05-17 Thread Ned Deily
On behalf of the Python development community and the Python 3.6 release
team, I'm happy to announce the availability of Python 3.6.0a1.
3.6.0a1 is the first of four planned alpha releases of Python 3.6,
the next major release of Python.  During the alpha phase, Python 3.6
remains under heavy development: additional features will be added
and existing features may be modified or deleted.  Please keep in mind
that this is a preview release and its use is not recommended for
production environments.

You can find Python 3.6.0a1 here:

https://www.python.org/downloads/release/python-360a1/ 

The next release of Python 3.6 will be 3.6.0a2, currently scheduled for
2016-06-13.

Enjoy!

--Ned
