The code made some half-hearted attemps to handle a MBS verbose query
missing the modulemd data, but it didn't do anything logically
consistent - fix it to consistently ignore such modules.
Code in MBSResolver.resolve_requires() to compute filtered_rpms()
assumed the response from MBS has a "rpms" key with binary RPMS
from the build, but this was never implemented.
If allow_only_compatible_base_modules=True, then it's an error if the
module buildrequires a non-xyz base module stream. Give an error message
that says how to override the base module in the modulemd file.
Overriding the platform stream with, e.g, platform:el8.3.1
is necessary to correctly pick up the right build dependencies for some
configurations. Match the fedpkg/rhpkg module-build way of doing this by adding
--buildrequires and --requires options to build_module_locally.
Fix some oddities in the DBResolver implementation of
get_compatible_base_module_modulemds() and make the MBSResolver version -
which was previously just buggy - match that. (Tests for the MBSResolver
version are added in a subsequent commit.)
* If an empty virtual_streams argument was passed in, *all* streams
were considered compatible. Throw an exception in this case - it
should be considered an error.
* If stream_version_lte=True, but the stream from the base module
wasn't in the form FOOx.y.z, then throw an exception. This was
previously treated like stream_version_lte=False, which is just
a recipe for confusion and mistakes.
test_get_reusable_module_use_latest_build() is rewritten to
comprehensively test all possibilities, including the case that changed
above.
test_add_default_modules_compatible_platforms() is changed to run
under allow_only_compatible_base_modules=False, since it expected
Fedora-style virtual streams (versions not in FOOx.y.z form, all
share the same stream), which doesn't make sense with
allow_only_compatible_base_modules=True.
The default LocalBuildConfiguration builds against Fedora - which has
ALLOW_ONLY_COMPATIBLE_BASE_MODULES = False on the server side. Match that
to avoid warnings that f33 isn't in <stream>x.y.z form.
config.allow_compatible_base_modules=False does different things for
build-requires selection and for module reuse. Clarify this in the config
key documentation.
(This config key is really: True: "do what RHEL expects"
False: "do what Fedora expects")
No implementations of MBS are using Greenwave, and there are no current plans
to do so. Koji Resolver will be sufficient for any usecase dependent on gating.
There is a need to rebuild the module builds done in CentOS 9 Stream
internally in MBS to include them in RHEL. This is currenly a hard task,
because the RPM components included in a module are usually
taken from HEAD of the branch defined by their `ref` value.
For the rebuild task, it means we would have to ensure that the HEAD
of all RPM components points to right commit hash right before we start
rebuilding CentOS 9 Stream module in internal MBS. This is very hard
and fragile thing to do, especially if there are two different modules
using the RPM component from the same branch. This is prone to race
condition and makes the rebuilds quite complex and in some cases
not possible to do without force pushes to RPM component repositories
which is not acceptable by internal dist-git policy.
This commit fixes it by allowing overriding the commit hash while
submitting the module build. This helps in the mentioned situation,
because we can keep internal RPM components branches in 1:1 sync with
CentOS 9 Stream branches and HEAD can always point to the same commit
in both internal and CentOS 9 Stream repositories.
When the module rebuild is submitted in internal MBS,
we can use this new feature to override the `ref` for each RPM component
so it points to particular commit and the requirement for HEAD to point
to this commit is no longer there.
The `ref` is overriden only internally in MBS (but it is recorded in logs
and in XMD section), so the input modulemd file is not altered. This is
the same logic as used for other overrides (`buildrequire_overrides` or
`side_tag`).
This does not bring any security problem, because it is already possible
to use commit hash in `ref`, so the package maintainer can already change
the commit hash to any particular commit by using this `ref` value.

This works around a case where tagging messages are missed for a build
with high reuse. In such a case, we can start out in the final batch,
but have incorrect tag state for reused components from previous
batches.
This will enable building modules from the new libmodulemd v3 format.
This format fixes major issue with modularity which enables clear
upgrade paths for multicontext modules.

This is a fix and feature in one. This patch enables to use static
contexts instead of module stream expansion. This fixes the issue with
upgrade path issue in dnf.

Since ComponentBuildTrace(s) get created with db_session.commit() call,
is is not possible to commit more items in bulk if they already have been flushed.
Current unit-tests' setup can be significantly sped up if items can be quickly
flushed on the fly and bulk-commited only once at the end. Moreover in general it
seems more appropriate/safer to handle this in before_flush as any implicit
or accidental flush could cause new build traces not to be created at all. As flush
is implicitly called before every commit anyway, this change shouldn't pose any harm.
