In the configuration script:
https://hg.python.org/cpython/file/47b2d1ff9743/configure.ac#l963

There is a special treatment done for FreeBSD, which is not needed, FreeBSD is perfectly fine with multiple digit in soversion.

This command was added by the changeset 6fc10306bf31.

[bapt]

Adding a patch on configure.ac (I bet configure should not be patched but regenerated)

Considering the comment here: http://bugs.python.org/issue1044395#msg47064 about ldconfig(1) the output of ldconfig(1) is buggy in that regard, and the ports tree does not depends on that anymore so it will perfectly accept the 2 digit name.

There are no known other things depending on that buggy output

koobs set versions: + Python 2.7, Python 3.4, Python 3.5

Do you seriously consider to modify Python 2.7 and 3.4? Can it break the backward compatibility?

I don't know how the SOVERSION thing is used.

Provide more information:
Here is a description of the problem with the FreeBSD ldconfig(1) problem and why it was a problem with libpython.so.*

https://wiki.freebsd.org/ports/fix_lib_depends

Here is the commit that adds the new methode for ports to lookup for libraries installed (not using ldconfig(1):
https://svnweb.freebsd.org/ports?view=revision&revision=322328
here is the commit that removes the ancient method:

I do not think it is worth changing python 2.7 or python 3.4 given the fact that the .so.1 symlink is not created (which imho it should be a good idea to create but let's go step by step)

Let's just do it for next python

[koobs]

@Haypo, yes, absolutely and no

We will backport to security-only branches ourselves.

[vstinner]

Oh, I expected such change to break backward compatibility. If it doesn't,
it's fine.

Koobs, would you like to commit the patch?

[koobs]

@Haypo, if you could take care of the change in default, 3.4 and 2.7, we can backport the rest downstream. Thank you :)

@bapt, can you create a separate issue to cover the "create foo.so.X' symlink" request, so python@ (freebsd team) can work to patch locally with an upstream reference

Issue bpo-23817: FreeBSD now uses "1.0" the the SOVERSION as other operating

[vstinner]

Let's just do it for next python

Ok.

I don't understand the purpose of SOVERSION, nor why it is an issue to not use dots on FreeBSD. So I don't want to change it in minor Python relases (2.7.x, 3.4.y).
