MAR-140: Updated developement requirements:

- Fixed to more specific versions due to older release needs.

MAR-139: Updated documentation and release notes:

- Document the new xmpp_prosody_package parameter.
- Add the breaking change informaiton in release notes (although most
likely nothing will be really broken).

MAR-139: Switch to using Prosody stable branch nightlies:

- Introduced additional parameter for specifying name of Prosody
package to install.
- Updated tests.

MAR-138: Updated documentation and release notes:

- Document the new xmpp_prosody_package parameter.

package to install.
- Updated tests.

MAR-134: Updated requirements:

- Remove workaround for broken pytest.
- Updated all requirements.

MAR-134: Fix Ansible warning about use of apt and with_items:

- The apt module can accept list of names already, and with_items is
considered to be deprecated in this regard (otherwise it would
end-up running one apt command per item).
- Changed multiple roles where apt was used together along with_items.

MAR-134: Make sure the Python setuptools are available for virtualenv use:

- Must be present for pipreqcheck virtual environments to get setup
correctly.
- Should be a good idea to include it in the default web server config
too.

- Updated command for getting the SSH key fingerprints to use the dig
tool.

MAR-132: Fix the handler that recreates the GnuPG keyring for duplicity:

- In Debian Stretch it can happen that a file (the GnuPG Unix socket)
dissappears in middle of removing the directory, causing
failures. Switch to using the "rm" command instead.

MAR-132: Pin packages as part of wsgi_website role test to ensure reproducability:

- Provide explicit list of packages being deployed. This should ensure
we can always reproduce the tests without being affected by new
releases of packages.

Debian 8 and 9).
- Deploy UTF-8 configuration in alternate locations depending on what
distro is being used.
- Force set-up of root password on Debian Stretch (default is to use
the unix_socket authentication).

MAR-132: Workarounds for wsgi_website Python virtual environment in Debian Stretch:

- Manually install setuptools in Python virtual environment on Debian
Stretch, otherwise the pkg-resources==0.0.0 package will mess with
pip freeze etc.
- Add back installation of futures package, even on Python 3 (since it
does not cause any harm).
- A small cleanup of how requirements are treated will be done in
separate ticket.

- Updated Molecule test preparation playbook to account for a number
of differences between Jessie and Stretch (mainly related to mailing
functionality).
- Renamed a couple of variables in test for sending out mails to make
it clearer what is being looked up as part of regex matching.

release they are ran against.

tests do not work with /bin/ss).

- Install more up-to-date version of pip. This fixes some issues
related to pip freeze detecting argparse and wsgiref in virtualenv
as separate packages.

Debian-specific behaviour. More details at:
- https://github.com/pypa/pip/issues/4022

- https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=871790

user (otherwise Ansible fails to template the file due to
permissions restrictions).

MAR-132: Added support for Debian 9 (Stretch) to php_website role:

- Implemented the necessary changes related to differences between PHP
versions and related paths (PHP 5 vs PHP 7).
- Set the shell for application system account explicitly (workaround
for Debian bug 865762 in Stretch).
- Updated Molecule tests to cover Debian 9.
- Updated Molecule test preparation playbook to account for a number
of differences between Jessie and Stretch (mainly related to mailing
functionality).
- Use more specific host groups in tests.
- Renamed a couple of variables in test for sending out mails to make
it clearer what is being looked up as part of regex matching.
- Updated Molecule tests where certain paths depend on what Debian
release they are ran against.
- Split-up Jessie-specific tests into separate file.

MAR-132: Added support for Debian 9 (Stretch) to web_server role:

client machine.

mandatory parameters (to be used with Stretch machine).
- Fixed invalid specification for hosts on top of which the
connectivity test should be run.
- Updated a couple of task names (avoiding to reference PHP 5).
- Updated documentation.

MAR-132: Added support for Debian 9 (Stretch) to mail_server role:

- Updated Molecule configuration to include set-up of additional
instances for testing.
- Updated configuration for test instances.
- Use separate clients in testing of Jessie/Stretch instances.
- Duplicate private keys/certificates for testing of mandatory
parameters on Debian 9.
- Refactored testing of mail deliveries (via swaks) to use
test-generated message ID - improves reliability and solves some
incompatibilities between swaks version in Jessie and Stretch.
- Updated tests for TLS testing to take into account newer OpenSSL
error/output messages. A bit of an ugly hack at the moment, but
beats duplicating tests for now.

- Do not use the ldap_entries option of the ldap_server role.
- Invoke the ldap_entry and ldap_attr modules directly.

MAR-132: Added support to xmpp_server role for Debian 9 (Stretch):

- Updated tests to include Debian 9 in testing. Existing private keys
are reused where possible (since most of the naming is identical
between the machines with jessie/stretch).
- Updated invocation of sendxmpp in tests as workaround for
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=854210.
- Updated testing of imported keys to accomodate differences between
gpg/gpg2 (used by apt-key in Jessie/Stretch).

tests, and make sure the netstat utility is available.

for connectivity tests).

for checking.

expire.
- Include information on whether the certificates has already expired.

MAR-129: Updated testsite configuration and playbooks:

- Specify path to inventory file in testsite Ansible configuration.

state: append does not work with stock ldap_entry - which is now
used instead of m_ldap_entry).
