There are no Python3 bindings for Samba. Porting will be a large effort, and as
upstream we don't want to maintain support for two Python versions. 

What do you need the Python3 bindings for? Perhaps there are alternatives.

I was looking what is keeping Python2 on the Ubuntu desktop. For the samba
bindings this is system-config-printer depending on gvfs-backends, depending on
samba-libs.

I think getting rid of the Python dependency in samba-libs is a much
easier to achieve goal here.

AFAICT The only reason that samba-libs depends on python is because
libsamba-net can do provisioning of a local DC (requires the 'samba'
package to be installed) by invoking the provision script using Python.

So if we could move that functionality out to a separate library that
is not included with samba-libs, we could drop the dependency on
python2 in samba-libs.

right, that would get rid off python libs and python-talloc.  However there is
another path in that nautilus-share depends on samba-common | samba-common-bin,
which depend on python-samba.

What does it need that dependency for? I would imagine it just uses
libsmbclient.

it doesn't use libsmbclient, it uses the

  net usershare

and

  testparm -s --parameter-name='usershare allow guests

commands.

Now, with:

Description: Nautilus extension to share folder using Samba
 Nautilus Share allows you to quickly share a folder from
 the GNOME Nautilus file manager without requiring root access.

it requires samba to work, so the package installs samba before running
anything. I still have to find out why it needs to run these two commands before
installing samba anyway.

Ah, of course. Why does it not have a hard dependency on Samba
in that case? It seems like sharing folders over SMB is impossible
without the server.

To reduce the size of the dependencies pulled in by default on the desktop
before these are needed.  This is a desktop sharing mechanism that's made
available by default, but we don't want the samba server installed (and
therefore enabled) by default on the desktop.

Please don't block fixing this python2 dependency of samba-libs on
fixing the other python2 issues in samba-common and samba-common-bin.
there are other packages (e.g. mpd) that Depend: samba-libs and do not
have this additional dependency.

Fixing the dependency of samba-libs on python-talloc in its own right
would be a win for minimal systems that run mpd but don't want to carry
around an unnecessary python interpreter.

Thanks for maintaining samba in debian!

Subject: python3 work ongoing in upstream

Date: Sun, 15 Oct 2017 18:27:24 +1300

Work is ongoing to make Samba use python3, but upstream still needs
much more work, and a more diverse set of contributors.  

Currently Red Hat is doing most of the work and I'm doing most of the
review, this needs to be broadened.  It is much more than 'just'
building the packages for python3, we use the C bindings extensively. 

Sorry,

Even this is a significant amount of work.  The challenge with
splitting up samba-libs is that there are a lot of libraries which
depend on each other.  Early Samba4 packages did split things into one
package per library, but it became unmanagable. 

One possible approach would be to create a samba-base-libs which
contains the things libsmbclient depends on, which hopefully does not
include python-talloc. 

The alternate, removing just the python dependency from samba-libs
would require more work I think, plus removing or re-structuring the
code in source4/libnet/provision.c that calls into python (rather than
python calling Samba, which is otherwise the pattern). 

I hope this helps.  I do need to make clear that we need significant
help if you wish to see progress here, plus work may be needed upstream
to change the libraries the build system produces.  On the hopeful
side, upstream Samba did merge patches to allow a build without linking
to python recently. 

Thanks!
