Description Dave Malcolm 2009-11-13 00:04:28 UTC
I'm working on adding a python 3 stack to Fedora 13, parallel-installable with
the main python 2 stack:
https://fedoraproject.org/wiki/Features/Python3F13

There are two approaches I'm experimenting with to packaging modules for python
3:
  (a) create an separate specfile/srpm for the python 3 version
  (b) extend an existing specfile so that it emits a python3- subpackage as
part of the build.

See: https://fedoraproject.org/wiki/PackagingDrafts/Python3

I'm working towards getting sphinx working on Python 3.

I experimented and was able to use python-jinja2.spec to create a python3-jinja2.spec that builds, using 2to3 at the end of the %prep phase, with some other fixups; it should be parallel-installable with the python 2 python-jinja2.  

I haven't properly tested it yet, though.

Do you know what upstream's plans are for python 3 support?  

I saw this:
http://groups.google.com/group/pocoo-libs/browse_thread/thread/efda29f8bddba84f/56aae1cd46bdadba?lnk=gst&q=python+3#56aae1cd46bdadba "Jinja2 for Python 3"
> I'm happy to accept a Jinja2 python3 port assuming it works in a way

> Maintaining two completely independent versions at the same time is

If I sent a patch that added a python3-jinja2 subpackage to the python-jinja2 build, would that be acceptable by you?

Thanks!

Comment 2 Bug Zapper 2009-11-16 15:29:59 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

Yes.

Reading http://groups.google.com/group/pocoo-libs/browse_thread/thread/468e2869a79a0737/1ec201d986cd843d, I think running 2to3 might not be enough.

Will have a look though.

Comment 4 Thomas Moschny 2010-02-06 12:34:57 UTC
Just to let you know that I'm working on a specfile that will produce a python3-jinja2 subpackage.

Just talked to upstream, and they will be releasing a new version which should have the 2to3 call in the setup.py within the next few days.

Comment 5 Thomas Moschny 2010-02-10 18:41:55 UTC
Ok, so here's what it currently looks like:
http://thm.fedorapeople.org/python-jinja2/python-jinja2.spec

Comments welcome.

Guess it doesn't make sense to commit that to rawhide yet, as long as bug 537266 blocks us?

Comment 7 Thomas Moschny 2010-07-13 22:32:04 UTC
Finally built python-jinja2-2.5-1 for rawhide, including a python3 subpackage. Please test. 

If it works well, we might consider issuing an F13 update as well. Therefore, not yet closing this bug.

Comment 8 Thomas Moschny 2010-08-19 00:53:05 UTC
Ok, seems there's not much interest in an F13 package.
