Current status of Unladen-Swallow

[Swapnil Talekar]

Hello,

I wanted to know about the current status of Unladen-Swallow project. The project page describes milestones only till 2009. 

Also, has the PEP 3146 been accepted by BDFL and the python community and what is the timeline for the merging of 

Unladen-Swallow with the Python 3k branch?

Thanks,

Swapnil

Hi Swapnil,

I've been busy with other work for Google, but I'm hoping to get some
time to push further on the upstream migration of Unladen Swallow into
CPython. We're still targeting CPython 3.3, though we may not get into
the cycle as early as we would have liked.

Thanks,
Collin Winter

Please please please do not let us get swamped. It is a really
exciting development. I use python a lot and would like to see it gain
momentum against competitors like scala or even c++.

Hey, I thought Unladen Swallow is dead.
Sure seems close to this.
It's really cool project, why is it so 'abandoned' right now? :<

Hi Arek,

Jeffrey and I have been pulled on to other projects of higher
importance to Google. Unfortunately, no-one from the Python
open-source community has been interested in picking up the merger
work, and since none of the original team is still full-time on the
project, it's moving very slowly. Finishing up the merger into the
py3k-jit branch is a high priority for me this quarter, but what
happens then is an open question.

Does that mean there is no longer a commitment to merging the JIT into
Python 3.2 -- or are you saying that WILL be done this quarter?

Really sorry to hear there isn't more interest from Google or others
in pushing this forward!

Thanks,
Gary

I need to get the code from the Unladen Swallow repository moved into
the python.org svn repo's py3k-jit branch. There are still a number of
issues that need work before final merger into Python 3.x is approved;
the final merger is contingent on resolving the remaining issues in
PEP 3146. The Python community will need to help resolve these
problems.

Thanks,
Collin Winter

That hasn't been on the table for quite some time. The deadline for
new features in 3.2 is some time in the next few weeks.

I think it's very unfortunate that Google does not seem to be committed
on getting the JIT into Python trunk. I think most of the python-dev
community does not believe it's worth the effort, especially as Google
did not seem to have picked up U-S for internal use (Youtube?).

Although my free time diminished quite a bit, I'm still willing to
commit time to U-S and/or jit-3k, but it seems a bit pointless if I'm
the only one working on that. Especially since I'm locked to python2.x
for the time being (maybe I should work on Numpy/Scipy instead?)

You might want to check out PyPy. They seem to be gaining momentum and
just released 1.4. Their JIT is getting great performance, sometimes
close to C++ speed.

This is sad.

Just to remind everyone who wishes to see Unladen merged into Python
3, help is needed (and welcomed!) to see it happening. You can see the
todo list at http://svn.python.org/view/python/branches/py3k-jit/JIT_TODO.txt?view=markup
and see if you can help write patches to merge the changes from
Unladen into Python itself or the Unladen branch of Python 3.

Yes, submit them to bugs.python.org.

Depends on which version. The released stuff that Collin and friends
did is still there. But the merging work is being done in the py3k-jit
branch at svn.python.org.

That I have no idea, but you can always ask for help.
