ParallelSSH
Add debian packaging files
This PR is a follow up of https://github.com/ParallelSSH/ssh2-python/pull/190 in an attempt to package all the parallel-ssh ecosystem to debian, the end goal being to have a python3-parallel-ssh package. I've already started working on parallel-ssh so it's coming next.
I had to disable two tests tests/test_channel.py:test_write_stdin and tests/test_sftp.py:test_mkdir in order to make it build locally, otherwise I had these errors:
_________________________ ChannelTest.test_write_stdin _________________________
self = <tests.test_channel.ChannelTest testMethod=test_write_stdin>
def test_write_stdin(self):
self._auth()
_in = u'writing to stdin'
chan = self.session.channel_new()
chan.open_session()
chan.request_exec('cat')
chan.write(_in + '\n')
self.assertEqual(chan.send_eof(), 0)
size, data = chan.read()
self.assertTrue(size > 0)
lines = [line.decode('utf-8') for line in data.splitlines()]
self.assertListEqual([_in], lines)
chan.close()

I don't know much about libssh but reading a closed channel might be the issue. And

I doubt '~' expansion works in a build environment
This builds fine locally, the steps are as follow (on a debian machine with buildessentials and debhelper installed, and maybe more):
# We copy the debian folder but we want to build with the 1.0.0 tree
git clone https://github.com/SCOTT-HAMILTON/ssh-python
mv ssh-python/debian .
rm -rf ssh-python
# we get the 1.0.0 tree
wget https://github.com/ParallelSSH/ssh-python/archive/refs/tags/1.0.0.tar.gz
tar -xf 1.0.0.tar.gz
mv ssh-python-1.0.0/ python3-ssh-1.0.0
mv debian python3-ssh-1.0.0
# we make the tar file
tar -czf python3-ssh_1.0.0.orig.tar.gz python3-ssh-1.0.0
# we install the build deps
cd python3-ssh-1.0.0
sudo mk-build-deps --install debian/control
rm -f python3-ssh-build-deps_1.0.0-1_all.deb
# and we finally build
debuild -us -uc
This works for me locally on ZorinOS 16.2. It also builds fine on OBS with debian testing and ubuntu 22.04 https://build.opensuse.org/package/show/home:ScottHamilton/python3-ssh.
PS:
I've noticed that the tests don't buid locally if the working directory is under /tmp. Maybe this is why the OBS build is failing, very strange ? Here is the error that I get for almost all the tests:

E ssh.exceptions.AuthenticationDenied: b"Access denied for 'publickey'. Authentication that can continue: publickey,password,keyboard-interactive"

Seems like an auth error.
