The search response from mocks/dnfjson is a map of responses indexed by the
comma-separated list of packages and globs being requested. Add support
for this.
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 cases are directly copied (or lightly adapted) from
rpmmd_mock/fixtures.
The purpose of the mocks/dnfjson package is to create files with data
for testing the dnfjson package without the need to call the dnf-json
script. Each public function creates a file with test responses in the
same format as the dnf-json script's responses (either valid results or
errors). The dnfjson.Solver can be configured to call the new
./cmd/mock-dnf-json program with the test data file as an argument and a
valid dnf-json request for input. The mock-dnf-json checks the input
request for unknown fields before responding with the contents of the
file.
Each test case file contains two responses, one for each command
supported by dnf-json: "depsolve" and "dump". mock-dnf-json responds
with the appropriate data based on the command in the request. This is
necessary for tests that require both commands in the same call, e.g.,
tests of the weldr API's moduleInfoHandler() which fetches a package
list and then needs to depsolve a subset of those packages.
There are also cases when we want one of the two responses to be an
error. The mock-dnf-json program will return with an error code if it
can successfully unmarshal the intended response into the dnfjson.Error
type.
