After a depsolve, each package inherits the `IgnoreSSL` value from its
repository configuration.
This information is not yet used. It will be used to expose this
information to osbuild's org.osbuild.curl stage.
The test data is updated to match the new behaviour:
The test repository config specifies `IgnoreSSL=true` and the packages
in the response inherit the value.
The repository checksums in the response from dnf-json aren't used
anywhere. Since we're making changes to dnf-json and depsolving, now is
a good opportunity to drop them completely.
Move package set chain collation to the distro package and add
repositories to the package sets while returning the package sets from
their source, i.e., the ImageType.PackageSets() method.
This also removes the concept of "base repositories". There are no
longer repositories that are added implicitly to all package sets but
instead each package set needs to specify *all* the repositories it will
be depsolved against.
This paves the way for the requirement we have for building RHEL 7
images with a RHEL 8 build root. The build root package set has to be
depsolved against RHEL 8 repositories without any "base repos" included.
This is now possible since package sets and repositories are explicitly
associated from the start and there is no implicit global repository
set.
The change requires adding a list of PackageSet names to the core
rpmmd.RepoConfig. In the cloud API, repositories that are limited to
specific package sets already contain the correct package set names and
these are now copied to the internal RepoConfig when converting types in
genRepoConfig().
The user-specified repositories are only associated with the payload
package sets like before.
On systems where `dnf` and the Python module aren't available, skip the
unit tests that call into the `dnf-json` script.
A test flag, `-force-dnf` is added to avoid this check and run the tests
unconditionally. This is useful for cases where the sniff check might
fail for wrong reasons or, more importantly, for cases where we want to
be sure the tests are ran and consider a missing `dnf` module to be an
error state (e.g., in CI).
Attach the repository configurations that are specific to a package set
directly on the PackageSet object. This simplifies the Depsolve()
signature and avoids requiring a `nil` when no additional repositories
are required. More importantly, it makes associating repositories to
package sets explicit, no longer relying on matching array indices or
map keys.
Defined a Hash() method on rpmmd.RepoConfig that calculates a SHA-256 ID
for a repository based on its configuration. Identical configurations
should produce the same ID. The Name and ImageTypeTags of a repository
aren't taken into account. These attributes affect a repository's
functional configuration.
This ID lets us change the way we handle repository configurations in a
few places:
- Preparing the depsolve job arguments is simpler since we have
predictable IDs for the repository configurations. We don't need to
rely on the index of a RepoConfig in a list to identify or access it,
which prevented us from building a list of all repository
configurations, since we needed them to be placed in the list in a
certain order.
- Associating packages from the depsolve result with the repository
configuration (in depsToRPMMD) no longer relies on an ID string
converted from and back to an integer index. Repositories define
their own IDs.
- Tests are a bit messier now but the changes simplify the main code, so
it's an acceptable trade-off.
- Fixtures need to change based on the repository configuration for
the test.
- We need to calculate the ID for the repository configuration for
the temporary file server URL.
Remove the single Depsolve function from the dnfjson package and the
depsolve command from the dnf-json tool. The new ChainDepsolve
functions and chain-depsolve command can handle single depsolves in the
same way so there's no need to keep (and have to maintain) two versions
of very similar code.
The ChainDepsolve function (in Go) and chain-depsolve command (in
Python) have been renamed to plain Depsolve and depsolve respectively,
since they are now general purpose depsolve functions.
The rpmrepo mock contains code to be used for testing depsolving. It
creates a file server that serves the metadata in test/data/testrepo and
can be used as a repository for depsolve tests.
The dnfjson tests perform a single depsolve with an expected response.
The chain depsolve tests perform multiple depsolves that should produce
the same expected response:
- Single transaction using the ChainDepsove() function
- Two transactions for the same packages split in two with no extra
repositories
- Two transactions for the same packages split in two with the main
repository redefined
