This merges the configuration from conf/config.py to
module_build_service/config.py. This also greatly simplifies the logic
in `init_config`. Additionally, `init_config` is no longer aware of
Flask. This will allow us to eventually break up the configuration
between the API and the backend.
Some of the config vars have default values, it is unncessary to keep
them in settings.
Note: Some vars are still in conf/config.py even they have the default
values, like the '*_url' vars, they're kept there just as placeholder
and reminder for changing while deploying the service.
Revert the changes in a207d97 and 9a2efb3, at this moment, some code
relies on both settings from frontend and backend, and it's inconvenient
to run unittests with config split up to frontend only and backend
only.
It turns out we still have some backend code relies on the flask app,
so revert the change to init_config, and make minor change to create
config object for frontend and backend with the same function.
1. init_web_config: create Config object for frontend, load
configuration from `web_config.py`.
2. init_backend_config: create Config for backend, load configuration
from `backend_config.py`.
And two new classes inherit from `Config` in config.py:
1. WebConfig: representing the orchestrator frontend web configuration
2. BackendConfig: representing the orchestrator backend workers
configuration
Before calling init_{web,backend}_config, check sys.argv, if
"fedmsg-hub*", "celery" or "build_module_locally" is present, it's
running as backend.
This patch allows to schedule tasks and launch workers with basic
config. To launch a worker:
celery -A module_build_service.celery_app -l info

look at the git history.
This patch separates the use of database session in different MBS components
and do not mix them together.
In general, MBS components could be separated as the REST API (implemented
based on Flask) and non-REST API including the backend build workflow
(implemented as a fedmsg consumer on top of fedmsg-hub and running
independently) and library shared by them. As a result, there are two kind of
database session used in MBS, one is created and managed by Flask-SQLAlchemy,
and another one is created from SQLAclhemy Session API directly. The goal of
this patch is to make ensure session object is used properly in the right
place.
All the changes follow these rules:
* REST API related code uses the session object db.session created and
managed by Flask-SQLAlchemy.
* Non-REST API related code uses the session object created with SQLAlchemy
Session API. Function make_db_session does that.
* Shared code does not created a new session object as much as possible.
Instead, it accepts an argument db_session.
The first two rules are applicable to tests as well.
Major changes:
* Switch tests back to run with a file-based SQLite database.
* make_session is renamed to make_db_session and SQLAlchemy connection pool
options are applied for PostgreSQL backend.
* Frontend Flask related code uses db.session
* Shared code by REST API and backend build workflow accepts SQLAlchemy session
object as an argument. For example, resolver class is constructed with a
database session, and some functions accepts an argument for database session.
* Build workflow related code use session object returned from make_db_session
and ensure db.session is not used.
* Only tests for views use db.session, and other tests use db_session fixture
to access database.
* All argument name session, that is for database access, are renamed to
db_session.
* Functions model_tests_init_data, reuse_component_init_data and
reuse_shared_userspace_init_data, which creates fixture data for
tests, are converted into pytest fixtures from original function
called inside setup_method or a test method. The reason of this
conversion is to use fixture ``db_session`` rather than create a
new one. That would also benefit the whole test suite to reduce the
number of SQLAlchemy session objects.

This patch introduces a new environment variable in order to allow running
tests with different database backend. This is useful particularly for running
tests inside container. With this change, it is possible run tests in following
combinations:
* Python 2 and SQLite
* Python 3 and SQLite
* Python 2 and PostgreSQL
* Python 3 and PostgreSQL
Package python-psycopg2 is installed in both Dockerfile-tests and
Dockerfile-tests-py3 in case of running tests with PostgreSQL.
A new script contrib/run-unittests.sh is added to make it easy to run tests. An
example:
contrib/run-unittests.sh --py3 --with-pgsql
that runs tests with Python 3 and PostgreSQL.

A base module's stream (the platform for RHEL) could have Z-stream suffix, e.g.
el8.0.0.z, this patch handles this Z-stream suffix and other potential streams
by returning the stream version as a float with configured suffix value. For
example, el8.1.0.z would be parsed as 080100.1. Note that, the 0.1 is totally
configured in config and it actually could be any value according to concrete
cases in practice.
Config STREAM_SUFFIXES is enabled in TestConfiguration so that tests depending
on the return value from ModuleBuild.get_stream_version are covered.
Part fixture of test TestMMDResolver.test_solve_virtual_streams is updated by
adding Z-stream suffix to platform:el8.2.0 in order to ensure this patch does
not break the MMD resolver.

This is needed for offline local builds to build a component which is
stored on local git repository.
This PR also adds OfflineLocalBuildConfiguration configuration class
for offline local builds to set the RESOLVER.
There are following changes introduced in this commit:
- The `koji_tag` of module builds imported from the local repositories
is now in `repofile:///etc/yum.repos.d/some.repo` format to store the
repository from which the module was imported to local MBS DB.
- The `koji_tag` of fake base module is set to empty `repofile://`
and in `MockModuleBuilder` the `conf.base_module_repofiles` list
is used as source for the repositories defining platform. We can't
simply use single repository, because there might be fedora.repo
and fedora-update.repo and so on.
- The list of default .repo files for platform are passed using the
`-r` switch in `build_module_locally` `mbs-manager` command.
- The LocalResolver (subclass of DBResolver) is added which is used
to resolve the build dependencies when building modules offline
locally.
- The `MockModuleBuilder` enables the buildrequired modules and
repositories from which they come in the mock config.
With this commit, it is possible to build testmodule locally
without any external infra.
When using a single Kerberos cache that is shared among threads,
Koji logins start failing because the cache gets corrupt. This uses
the Linux kernel keyring to store a Kerberos cache per MBS thread.

Fixes#832.
The slow tests there are hobbled by this `retry(...)` decorator with hardcoded
timeouts. We want those to be relatively long in prod and relatively short in
test and dev.
We used to do x509 authn a long time ago. We have since stopped doing
that, but we kept all of thise confusing SSL/TLS support stuff.
This removes all that, and fixes#685.
