Re: [Jython-dev] funding jython development

[Jeff A. <ja...@fa...>]

Hi Albert, thanks for your interest.

1. I'm an active developer, and a few others, either submitting code 
(https://hg.python.org/jython/) or answering on issues or the web site. 
It is fair to say momentum is low, but 2.7.2b looks within reach and I'd 
really like to get the fix you mention out there. (I was on the verge of 
re-assessing our "blockers".) When that is out for evaluation, by good 
folk like you, I intend to revivify Jython 3.

2. We are a Python Software Foundation project and grateful for the 
continuing support we get in terms of infrastructure. No money changes 
hands AFAIK: I'm not sure we would know what to do with actual funding. 
(The PSF might.) We are all volunteers: I am working entirely in my own 
time. Contributors in the past sometimes had employer support/time. New 
contributors would be a help, and we try to be supportive when someone 
drops in.

3. I don't properly understand your question 3. (So simple answer "No 
and er ... ".) I understand RPython to be a restricted dialect 
underlying the PyPy implementation, but have not delved further. What do 
you mean by "JVM backend" here? We make Java bytecode, but it depends on 
the Jython runtime. I believe there was a compiler to Java source once, 
but support stopped before I joined the project. I have a lot of 
alternative ideas for the Jython 3 runtime (we can do much better), but 
I also see value in continuity.
