MAR-192: Fix incorrect prompt for wsgi_website virtual environments:

- Ensure that the virtualenv indicator string ends with a whitespace.
- The virtualenv prompt parameter behaves slightly different between
the versions of Debian 11 Bullseye and Debian 12 Bookworm - the
former being a bit more user-friendly.
- Recreate virtual environment if the prompt does not match-up.

MAR-154: Improve incorrect Python version handling in virtual environments:

- This should be helpful when performing distribution upgrades as
well (since it should be able to automatically detect a mismatch
now).

MAR-154: Drop suppor for Python 2.7 from the wsgi_website role:

- Mostly a matter of dropping the Python version parameter, and
updating some package versioning to account for Python 3 only.

MAR-191: Drop support for Debian 11 Buster from the wsgi_website role:

- Get rid of the workaround that used to cause issues in some of the
previous versions of Debian while at it. This should no longer pose
an issue.

MAR-151: Added support for Debian 10 Buster to wsgi_website role:

- Updated role reference documentaiton.
- Updated role meta information.
- Updated tests.
- Replace the installation of libmariadbclient-dev-compat library with
atftp - the actual package is differently named under Debian Stretch
and Debian Buster (which would complicate the test without any
benefits).
- Drop the fix for root mail alias in Vagrant image - seems it's no
longer a problem.
- Split-up the test for web application user since it's not possible
to keep it all under one parametrised test due to differences in
assigned system UID numbers for Debian Stretch and Debian Buster.
- Make the test for web application user less dependant on what the
actual UID number is in case of default value. By default user
should be created as system user, which means its UID number should
be less than 1000.

MAR-163: Reformat multiple skip-QA directives and remove some unnecessary ones:

- Update codes used to identify the disabled QA checks.
- Switch to using new syntax that disables only a specific QA check
instead of all of them on a single task.
- Drop disabling QA checks related to octal file permissions (this was
most likely bug in older versions of ansible-lint).

MAR-163: Reformat skip-QA directives for ANSIBLE0012 (Commands should not change things if nothing needs doing):

- Update codes used to identify the disabled QA checks.
- Switch to using new syntax that disables only a specific QA check
instead of all of them on a single task.
- Drop disabling QA checks on two command tasks, since they actually
use the "creates" directive (therefore passing the QA check).

MAR-177: Do not pin pip/setuptools to specific versions when setting up Python virtual environment:

- Provided more details for the pkg-resources workaround.
- Skip installing latest version of pip - it will get installed
automatically via the virtualenv command already.
- Do not pin the setuptools package when installing.
- Updated release notes.

MAR-159: Drop the use futures_version and gunicorn_version parameters from the wsgi_website role:

- Remove related tasks, Gunicorn/Futures should instead be installed
via the requirements file instead.
- Restructure tasks, moving them from the requirements.yml into
main.yml.
- Small typo fix for one of the variables.

MAR-148: Fixed Ansible warnings for wsgi_website role:

- Use the length filter for conditionals that involve lists.

MAR-148: Fixing linting errors:

- Do not compare against booleans when value is already boolean in
"when" conditions.
- Do not compare variables to empty strings in "when" conditions. This
change currently works only for complex variables (stuff can break
badly in case of simple variables in current default Ansible
configuration).

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-135: Switch to using run_handlers instead of handlers as variable:

- Updated all roles to now depend on run_handlers being set to True in
order to force execution of handlers.

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.

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

- 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).
- 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.
- Remove the /bin/ss utility instead of renaming it (testinfra socket
tests do not work with /bin/ss).

MAR-132: Fix virtual environment set-up in wsgi_website role:

- 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.
- Remove the pkg-resources package from virtualenv. Workaround for
Debian-specific behaviour. More details at:
- https://github.com/pypa/pip/issues/4022
- https://bugs.launchpad.net/ubuntu/+source/python-pip/+bug/1635463
- https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=871790
- Deploy Gunicorn requirements file without switching to website admin
user (otherwise Ansible fails to template the file due to
permissions restrictions).
- Updated test for checking packages installed in the virtualenv.

MAR-131: Added support for specifying Python version in wsgi_website role:

- Introduced additional role parameter for specifying the Python
version.
- Updated tests to verify new functionality.
- Fixed existing tests to account for differences between Python 2 and
Python 3 - including changes to WSGI test applications.
- Updated documentation, documenting new parameter and fixing one
minor typo.
- Updated release notes.
- Bumped default version of Gunicorn/futures used.

MAR-129: Fixed installation of packages in virtualenv for wsgi_website role:

- Make sure packages are only installed if they are defined.

MAR-129: Updated wsgi_website role for Ansible 2.5.x and new Molecule:

- Include top-level linting configuration in test configuration file.
- Fixed linting errors.
- Updated Ansible deprecation warnings related to use of
state=installed with apt module.
- Updated how hosts are being referenced in tests.
- Rename the 'ss' utility in order to properly test socket
connectivity as a workaround for Testinfra bug.

MAR-122: Fixed handling of complex package versions for pip with Ansible 2.x:

- Use list for installing specific version of pip in the "pipreqcheck" virtual
environment in common role.
- Removed superficious (and incorrect) definition for application admin username
in wsgi_website role.
- Updated test playbook for wsgi_website role to test the fix.
- Switched to passing-in package list for installing packages in virtual
environment instead of using "with_items" in wsgi_website role.

MAR-118: Replaced handler with parametrised name in wsgi_website:

- Updated wsgi_website role.
- Replaced handler with parametrised name used for restarting a single service
with a generic handler that will restart zero or more services.
- Updated test site roles to introduce explicit handler in them.
- Updated usage instructions to include set-up of explicit handler for
restarting the Wiki service.

MAR-114: Updated task syntax for web server/application roles:

- Updated web_server, php_website, and wsgi_website roles.
- Added and removed quoting where it makes sense.
- Switched to using expanded syntax (instead of one-liners).
- Updated ordering of arguments in task definitions.

MAR-114: Moved set_fact for wsgi_website and php_website roles:

- Moved set_fact for setting application admin, user, and home directory into
defaults/main.yml.
- Updated test playbook for wsgi_website to fixate the ptpython and dnspython
versions (including their dependencies).
- Updated tests for wsgi_website to use new fixated versions for ptpython,
dnspython, and their dependencies.

MAR-33: Implemented tests for the wsgi_website role:

- Updated test playbook to have better coverage of functionality.
- Fixed some additional permission mode issues (leading zero).
- Use expanded syntax for deploying TLS material in order to avoid mangling of
TABs.
- Implemented proper WSGI applications in order to test everything.
- Implemented tests covering mandatory parameters, optional parameters, and the
use of WSGI requirements/Paster.

MAR-33: Added initial scaffolding for wsgi_website tests:

- Added Molecule configuration file.
- Implemented test playbook that sets-up three separate instances of WSGI
website in order to test all variations of parameters.
- Added name for the set_fact task.
- Fixed linting errors related to mode that lacks leading zero.
- Added skip_ansible_lint tag for command that creates the Python virtual
environment.
- Added missing become keyword wherever become_user is specified.
- Fixed invalid parameter name for specifying if HTTPS should be enforced or
not.
- Added small initial sample WSGI apps that get deployed.
- Added static/media sample files.
- Added TLS material.
- Added initial dummy test file.
