Hi,
On behalf of RPM and DNF teams, I would like to highlight changes that
have appeared in our packages in 2020. Thanks everyone for your bug
reports and patches!
RPM
---
$ rpm --eval '%[0 < 1 ? "true" : "false"]'
* Support for complex expressions and conditionals with short-circuit
logic etc in macros via %[...] and %{expr:...}
$ rpm --eval '%[v"1.10" > v"1.2"]'
* Rpm versions as native objects in expressions, eg v"3.1-1"
$ rpmbuild
* Parametric macro dependency generators offer a lightning fast way
to generate dependencies where applicable
* Meta dependencies, eg Requires(meta) allow specifying dependencies
without introducing ordering constraints
* Dependency generation based on MIME types
$ rpm --rebuilddb
* New sqlite3 backend
* More robust than the Berkley DB backend
* SQLite3 has also a more permissive license than the latest BDB
* NDB backend promoted to stable
* Support for migration (reading) from BDB databases without linking
to BDB
DNF
---
$ dnf needs-restarting
* Introduced the needs-restarting.d drop-in directory
$ dnf reposync
* Fixed modularity issues, able to sync modular repos correctly
$ dnf groups-manager
* yum-groups-manager is back
* Upstream only, to be released in Fedora soon
* https://github.com/rpm-software-management/dnf-plugins-core/pull/412
$ dnf module switch-to
* Switches the module stream and also performs distro-sync on the new
stream content
$ dnf history store/replay
* New commands for storing a transaction and replaying it on another
system
$ dnf system-upgrade
* The code was refactored to use the store/replay feature in the
background
* Landing in Fedora now
$ dnf system-upgrade
* Comps groups are upgraded during the system upgrades
$ dnf offline-upgrade
$ dnf offline-distrosync
* New commands to upgrade your system on reboot
MICRODNF
--------
$ microdnf module <enable|reset|disable>
* New commands for managing modules
$ microdnf --config
* Microdnf reads values from dnf.conf
* It is possible to specify a path to the config
$ microdnf --refresh
* Force repodata refresh
* Microdnf also honors the metadata_expire configuration option
LIBDNF
------
* Many changes to make the DNF features available in microdnf and
PackageKit (and Gnome Software)
DNF 5
-----
* The goal is to remove redundant code and make sure all tools built
on top libdnf work the same (DNF currently uses a different code path
than microdnf and PackageKit)
* We're behind the plan because we spent the time fixing DNF 4 stack
instead (modularity, new features, crashes, etc.)
* There's a COPR repo with unstable nightlies:
* dnf copr enable rpmsoftwaremanagement/dnf5-unstable
* dnf install microdnf5
* dnf install python3-libdnf5 perl5-libdnf ruby-libdnf
* WARNING: Here be dragons! The software is not ready for general
use yet.
* The next steps are: finish the core functionality, stabilize the
API and make the package available in Fedora in parallel with the DNF 4
stack
