class rpmdeplint.DependencyAnalyzer(repos, packages, arch=None)

An object which checks packages against provided repos for dependency satisfiability.

Construct an instance for a particular set of packages you want to test, with the repos you want to test against. Then call the individual checking methods to perform each check.

Parameters:

• repos – An iterable of rpmdeplint.repodata.Repo instances
• packages – An iterable of RPM package paths to be tested

solvables = None

List of solv.Solvable to be tested (corresponding to packages parameter)

repos_by_name = None

Mapping of {repo name: rpmdeplint.repodata.Repo}

try_to_install_all()

Try to solve the goal of installing each of the packages under test, starting from an empty package set.

Returns:Tuple of (bool ok?, DependencySet)

find_repoclosure_problems()

Checks for any package in the repos which would have unsatisfied dependencies, if the packages under test were added to the repos.

This applies some extra constraints to prevent the solver from finding a solution which involves downgrading or installing an older package, which is technically a valid solution but is not expected if the packages are supposed to be updates.

Returns:List of str problem descriptions if any problems were found

find_conflicts()

Find undeclared file conflicts in the packages under test.

Returns:List of str describing each conflict found (or empty list if no conflicts were found)

find_upgrade_problems()

Checks for any package in the repos which would upgrade or obsolete the packages under test.

Returns:List of str describing each upgrade problem found (or empty list if no problems were found)

class rpmdeplint.DependencySet

Contains dependency information from trying to install the packages under test.

overall_problems

List of str dependency problems found (if any)

packages_with_problems

List of solv.Solvable which had dependency problems

package_dependencies

Dict in the form {package: {‘dependencies’: list of packages, ‘problems’: list of problems}}

class rpmdeplint.repodata.Repo(repo_name, baseurl=None, metalink=None)

Represents a Yum (“repomd”) package repository to test dependencies against.

Parameters:

• repo_name – Name of the repository, for example “fedora-updates” (used in problems and error messages)
• baseurl – URL or filesystem path to the base of the repository (there should be a repodata subdirectory under this)
• metalink – URL to a Metalink file describing mirrors where the repository can be found

Exactly one of the baseurl or metalink parameters must be supplied.

classmethod from_yum_config()

Yields Repo instances loaded from the system-wide Yum configuration in /etc/yum.conf and /etc/yum.repos.d/.
