== Summary == Dnf team wants to change a default setting for the repo option `skip_if_unavailable` to `FALSE`.

== Owner == * Name: [[User:jmracek| Jaroslav Mracek]] * Email: jmracek@redhat.com

== Detailed Description ==

Dnf team wants to change a default setting for the repo option `skip_if_unavailable` to `FALSE`. The option is responsible for behavior when metadata of a repository is unavailable. When it is set to false, it will stop on the first unavailable repository with raising an error. The default behavior could be overwritten by a configuration of each repository or in dnf by configuration in /etc/dnf/dnf.conf.

The behavior is not new, because it was used already by YUM, and the behavior is really essential because all Fedora ropos are already shipped with `skip_if_unavailable=FALSE`.

The change will be applied in libdnf library, and the changed behavior will be visible for all direct and indirect users of the library: dnf, microdnf, PackageKit, ... .

== Benefit to Fedora ==

It should provide a better security because some Important updates from third-party repositories could be present in temporary unavailable repository, but user can easily overlook it during `dnf update` because the issue is reported as a warning.

== Scope == * Proposal owners: ** Backport the following upstream pull requests into the DNF stack on Fedora: https://github.com/rpm-software-management/libdnf/pull/701 * Other developers: N/A * Release engineering: [https://pagure.io/releng/issue/8307 #8307] * Policies and guidelines: N/A * Trademark approval: not needed for this Change

== How To Test == Edit .repo file in /etc/yum.repos.d/* and set an url that is not accessible.

Case 1: No skip_if_unavailable in the repo file, in /etc/dnf/dnf.conf or overwritten from commandline using `--setopt`. Any command that requires available repositories like `dnf repoquery` will fail due to an error `Error: Failed to synchronize cache for repo '<repo_ID>'`

Case 2: Set skip_if_unavailable=true in the repo file. Any command that requires available repositories like `dnf repoquery` will not fail due to missing metadata of the `<repo_id>`

== User Experience ==

Broken repositories are recognized early, enabling the users to act upon them by double-checking their repository configuration or filing bugs, instead of assuming no upgrades are available.

== Dependencies == Depend packages - dnf, microdnf, PackageKit

There are no changes on which completion of this change depends.

== Contingency Plan == * Contingency mechanism: (What to do? Who will do it?) The change requires a merge and a release of the pull-request https://github.com/rpm-software-management/libdnf/pull/701

* Contingency deadline: Should be delivered before 2019-07-24. * Blocks release? No * Blocks product? No
