look at the git history.
Currently, we generate `Conflicts` for ursine RPMs conflicting with
modular RPMs only when Ursa Prime is used for the base module. This
commit changes it, so these Conflicts are generated everytime.
The reason is that modular RPMs should always be preferred in the
buildroot over the ursine RPMs no matter what is their NVR. So far,
this has been guarded on Koji side by using external repos, but
we need to move away from external repo or at least use "bare"
merge mode which basically means we won't get this feature for free
from Koji.
The reason why we need to move away from external repos or use "bare"
merge mode is that without this, the Koji removes RPMs sharing the same
name but different version/release from the buildroot and only keeps
the latest one. This is an issue in situation when you need two
versions of single RPM in a buildroot comming from two modules.
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.

Currently, we are using just `conf.arches` and `conf.base_module_arches`
to define the list of arches for which the RPMs in a submitted module are
built. This is not enough, because RCM needs to generate modules based
on the base modules which should use different arches.
This commit changes the MBS to take the list of arches from the buildrequired
module build. It checks the buildrequires for "privileged" module or base
module and if it finds such module, it queries the Koji to find out the list
of arches to set for the module.
The "privileged" module is a module which can override base module arches
or disttag. Previously, these modules have been defined by
`allowed_disttag_marking_module_names` config option. In this commit,
this has been renamed to `allowed_privileged_module_names`.
The list of arches are stored per module build in new table represented
by ModuleArch class and are m:n mapped to ModuleBuild.
This also moves the methods load_mmd and load_mmd_file to
module_build_service.utils.general.
This also removes some MSE unit tests with a mix of positive and
negative streams since this is not supported in libmodulemd v2. The
user will be presented with a syntax error if they try to submit
such a modulemd file.
This commit introduces new to_text_type helper method and calls it
for return value of all mmd.dumps() calls. That way, we always
end up with proper unicode string represntation on both python
major versions.
This commit also adds unicode character to description of all
the yaml files we use in the tests so we can be sure MBS can
handle unicode characters properly.
This might be temporary fix, depending on the result of discussion
at https://github.com/fedora-modularity/libmodulemd/issues/184.
