</div></div>We will need to kill Python 2.6 at some point. It probably won't be<br>
this year, but it eventually has to happen. We should focus on<br>
discussing when it will happen and how we'll handle it. We will<br>
probably keep Python 2.6 in one catalog release, and kill it in<br>
another. Users who want to stick with 2.6 will have the option of<br>
staying with an old catalog as long as they want.<br></blockquote><div><br></div><div style>Yes that's something we could say.</div><div style>We could also let users keep the old version of the package even if they are using a more recent catalog.</div>
<div style><br></div><div style>Thanks to having renamed libraries package based on their soname, that's something that is possible for libraries and I personnally think it's a good thing.</div><div style>For example, if someone compiled a binary against libssl0.9.8, they will not be forced to stick to an old catalog just because of that binary (a binary that might not even be recompiled against libssl1.0.0).</div>
<div style>They will be able to move on to a more recent catalog while keeping the obsolete libssl0.9.8 package installed.</div><div style><br></div><div style>I would think we could apply the same logic to python packages.</div>

</div>Python 3 is not backward compatible, so modules will live in a<br>
different place. The main question is whether we will make the module<br>
installation path specific to the minor version, or only to the major<br>
version. In other words, will it be /opt/csw/lib/python3.3 or<br>
something like /opt/csw/share/python3. Debian is doing the latter. We<br>
haven't really thought about Python 3 handling yet.<br></blockquote><div><br></div><div><br></div><div style>Ok, maybe we should try to include python 3 in the reflection to be sure it doesn't bring some new problem. This way we could define a consistent policy for Python.</div>
<div style><br></div><div style>If I understand well, we will prefix all python 3 modules with CSWpy33- our CSWpy3- ?</div><div style><br></div><div style>It seems for python 3, they tried to define a stable ABI / API subset: <a href="http://www.python.org/dev/peps/pep-0384/">http://www.python.org/dev/peps/pep-0384/</a><br>
