Fedora 31 System-Wide Change proposal: Set skip_if_unavailable default to false
https://fedoraproject.org/wiki/Changes/Set_skip_if_unavailable_default_to...
== 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(a)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
