DNF5 x DNF4 differences

Changes on the API:

PackageSet::operator[]

It was removed due to insufficient O(n^2) performance. Use PackageSet iterator to access the data instead.

Package::get_epoch()

The return type was changed from unsigned long to std::string.

DNF: Package.size, libdnf: dnf_package_get_size()

The return value was ambiguous, returning either package or install size. Use Package::get_package_size() and Package::get_install_size() instead.

dnf_sack_set_installonly, dnf_sack_get_installonly, dnf_sack_set_installonly_limit, dnf_sack_get_installonly_limit

The functions were dropped as unneeded. The installonly packages are taken directly from main Conf in Base.

Query::filter() - HY_PKG_UPGRADES_BY_PRIORITY, HY_PKG_OBSOLETES_BY_PRIORITY, HY_PKG_LATEST_PER_ARCH_BY_PRIORITY

The priority filter was separated into a standalone method. Combine query.filter_priority() with query.filter_latest_evr() or another filter to achieve the original functionality.

Query::filter() - HY_PKG_LATEST

The filter was replaced with filter_latest_evr() which has the same behavior as HY_PKG_LATEST_PER_ARCH

Changes on the command line:

Commands cannot have optional subcommands and optional arguments. Is some cases subcommand can have the same string as an argument. It means there is a difficulty to find advisory for package with the name list, info, or summary. dnf history info <transaction ID> -> dnf history --info <transaction ID> dnf updateinfo info -> dnf updateinfo --info

Options that cannot be applied to all command or can be applied but without any effect should be removed from general options and implemented only for related commands --best, --nobest are only related several transaction commands

Renaming boolean options to format --<option>, and --no-<option> --nobest -> --no-best. Proposing to keep --nobest as a deprecated option.

Upgrade command

  • New dnf5 option --minimal (upgrade-minimal command still exists as a compatibility alias for upgrade --minimal).

Repoquery command

  • Dropped: -a/--all, --alldeps, --nevra options, their behavior is and has been the default for both dnf4 and dnf5. The options are no longer needed.
  • Dopped: --nvr, --envra options. They are no longer supported.
