MBS will iterate through all the builds in buildrequires to determine
the expected list of arches on the associated Koji tag. In some cases,
these builds do not have a Koji tag. They should be skipped for this
operation.

Please note that this patch does not change the use of database session
in MBS. So, in the frontend, the database session is still managed by
Flask-SQLAlchemy, that is the db.session. And the backend, running event
handlers, has its own database session created from SQLAclehmy session
API directly.
This patch aims to reduce the number of scoped_session created when call
original function make_db_session. For technical detailed information,
please refer to SQLAlchemy documentation Contextual/Thread-local
Sessions.
As a result, a global scoped_session is accessible from the
code running inside backend, both the event handlers and functions
called from handlers. The library code shared by frontend and backend,
like resolvers, has no change.
Similarly, db.session is only used to recreate database for every test.

This also removes the outdated comments around authorship of each
file. If there is still interest in this information, one can just
look at the git history.
PR #1331 made the assumption that the Ursa Major ursine RPMs were at
xmd["mbs"]["ursine_rpms"], but they are actually at
xmd["mbs"]["buildrequires"]["platform"]["ursine_rpms"]. This commit
handles the ursine RPMs generated by handle_collisions_with_base_module_rpms
separately since the base module the RPMs came from are not tracked in
that function.
Some code create a dict in this way:
some_var = {}
some_var["a"] = 100
some_var["b"] = 200
Using dict literal could make these lines a little bit simpler.

When recover_orphaned_artifact is called for module-build-macros
and the module-build-macros is not tagged in the -build Koji tag,
then the tag_artifacts() is called to tag it there.
This is correct, but the issue is that module-build-macros need
to be added to "build" and "srpm-build" Koji tag groups, otherwise
it is not installed in the buildroot by default.
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 fixes module builds which sets the `buildopts` for something else
than the RPM whitelist.
Before this commit, when `buildopts` was set, the RPM whitelist was
always taken from the buildopts even if it was not defined there.
This resulted in empty `rpm_whitelist` and therefore no pkglist set
in Koji tag.
In this commit, MBS uses whitelist from `buildopts` only if it is
really set by the module maintainer.
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.
Previously MockModuleBuilder was checking the module state to see if
it should run a final createrepo, but since eafa93037f, finalize() is
called before changing the module state; add an explicit boolean to
GenericBuilder.finalize() to avoid worrying about ordering.
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.
The Koji tag extra options used to be hard-coded and to change them,
we had to release new MBS version.
We do not change them often, but right now fedora-infra is requesting
to use new `mock.new_chroot` option and we need to release new MBS
because of that.
This commit makes such changes easier in the future.
Currently, the Koji tags have properly set the scrmod- prefix, but
the build target still sets module- prefix even for scratch builds.
In this commit, build target has the scrmod- prefix too.
- Keep scratch module builds in the 'done' state.
- Make koji tagging for scratch modules unique so the same
commit can be resubmitted.
- Use alternate prefix for scratch module build components so they can
be identified later.
- Prevent scratch build components from being reused.
- Assorted code and comment cleanup.

Fedora 30 now includes rpm-4.14.2.1-4.fc30 with support for

This commit includes the backport of the changes to `krb_login` in
https://pagure.io/koji/pull-request/1187. This change is required
for our separate threads to use a separate Kerberos context per thread.
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.
See https://web.mit.edu/kerberos/krb5-1.12/doc/basic/ccache_def.html
MBS calls some read-only Koji APIs which does not require to log into a

session and use anonymous session properly to call those read-only APIs.

For some modules, modularity-wg wants to be able to ship the "-devel" modules containing
the RPMs which are normally filtered out from the module.
This PR generates second Koji CG module with -devel suffix in a name with final modulemd
files containing the filtered out RPMs.
