This patch drops message objects, defined by class BaseMessage and its
subclasses, and pass event info arguments to event handler directly.
Different event handler requires different arguments to handle a kind of
specific event. The event info is parsed from the raw message received
from message bus.

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This also removes the outdated comments around authorship of each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.
* xmd/mbs is always set if it is not present in xmd, so move the code on
the top of function. This change is also helpful for accessing keys
under xmd/mbs.
* By setting xmd/mbs in the beginning, code is simplified to get
disttag_marking and virtual_streams. The result is much straightforwar
for getting a default value for them.
* Move disttag_marking validation code next to the line getting
disttag_marking from xmd/mbs. As a result, the code structure is
easier to read as getting disttag_marking and validate it, getting
virtual_streams and validate.
* Rewrite the part of code for check_buildrequires. Always set
xmd/mbs/buildrequires if it is not present and check_buildrequires is
set to True, as it is required by
ModuleBuild.get_buildrequired_base_modules.
* Using in operator instead of dict.get to check if key koji_tag exists.
Using dict.get would be ambiguous because even if koji_tag exists
under xmd/mbs, but due to its value is set to None occasionally, there
is still a message logged to tell koji_tag is not set.
* Rwrite all lines of code for updating virtual streams. A new method
update_virtual_streams is added to ModuleBuild. This also fixes
FACTORY-4561.
* Tests are added for the rewrite of virtual streams update.

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.

To do this, we need to use the same database session in import_mmd as in
ModuleBuild.get_buildrequired_base_modules, otherwise, the returned
ModuleBuild objects are in a detached state.
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.
Currently, the PLATFORM_ID is parsed from the `/etc/os-release`. This
is good default value, but sometimes you want to build module locally
against the different platform stream.
For example building on platform:f29 against the platform:f30 modules. In
that case, we need to be able to override the host PLATFORM_ID and
set it manually chosen value.
When importing modules for offline local builds from local repositories,
the XMD section does not have to be set at all - it gets removed during
the compose and is also MBS specific.
We need to be able to import such MMDs using the `import_mmd` method
in order to make --offline local builds working.
This commit adds new `check_buildrequires` bool kwarg in `import_mmd`
method to disable `xmd["buildrequires"]` checks to fix this.
These module builds will basically act as metadata-only module builds.
This will be more useful as additional features stem from these types
of builds.
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.
This is the first PR in many for Offline local builds. This PR:
- Adds --offline flag to build_module_locally mbs-manager command to enable
offline local builds.
- If this flag is used, new `import_builds_from_local_dnf_repos` method is
called which uses DNF API to get all the available installable modulemd
files and imports each module into MBS local SQLite database.
- It also adds fake "platform:stream" module based on the /etc/os-release,
so the buildrequirements of the imported modules are satisfied.
The idea here is that in upcoming commits, I will create LocalResolver
which will be similar to DBResolver with some extra rules to resolve
local module builds. This new LocalResolver will still be based on
the models.ModuleBuild methods and therefore we need the modules
imported in database.
When importing a base module, we must ensure the value that will be
used in the RPM disttags doesn't contain a dash since a dash isn't
allowed in the release field of the NVR.
MBS uses the base module's stream that was buildrequired by the module
in the RPM disttags for that module build. The stream name may not be
ideal for all situations, so now this is customizable by setting the
xmd['mbs']['disttag_marking'] in the base module's modulemd.
- 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.

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.
We always set the "context" to DEFAULT_MODULE_CONTEXT from the historical
reasons - the context was not stored in the database before and we stored
just the build_context/runtime_context. But this is no longer true for
some time.
In this commit, the context is respected and stored in the database when
importing module using the `import_mmd` method. If the context is not set
in the imported MMD, the DEFAULT_MODULE_CONTEXT is used.
Future use cases will require the ability to find compatible module builds
to buildrequire based on the base module the module used to build. This
commit adds an association table that will contain module build IDs
and the base module they buildrequire.
Addresses FACTORY-3353
During I'm reading through the code base to learn MBS, I found out some
typos and minor issues in some other docstrings, and I also found some
docstrings with extra informative description could make it easier to
understand the code.

1. Changed ModuleBuild's context property to db column, it's
non-nullable and default value is '00000000' to keep it consistent
with previous behaviour.
2. Changed ModuleBuild.contexts_from_mmd to return a tuple of
(ref_build_context, build_context, runtime_context, context).
3. Updated tests affected by this change.
koji now supports tags with max length of 256, we can use
more informative tag name instead of the hash one.
The new format of koji tag name is:
module-<name>-<stream>-<version>-<context>
However when the generated tag's length > (256 - len('build')), we
fallback to the old way of name in hash format (module-<hash>).
In this change, koji tag is always generated from MBS itself, even
with pdc resolver.
